THE TECHNICAL FIELD

This group of inventions refers in particular to a method of manufacture of a concrete platform on which establish bulky structure, such as a turbine, generator and etc. to concrete platform and to the fitting.

BACKGROUND OF THE INVENTION

As a rule, known concrete platform on which establish bulky design, vibrates in the process, for example, turbine, generator etc, made of a large volume of non-reinforced concrete and rebar.

Cross etc. part of the base plate in such a concrete platform on which establish bulky design, performed with larger cross-sectional area (for example, with a minimum width of 2 m, and a height not less than 2 m) compared to a cross-beam used for structures such as houses, etc. for the ability to keep a large load. For attaching the above heavy construction to the part of the base plate to use a lot of metal embedded in this part of the base plate which may include plates, bolts, anchor blocks etc.

At the time of manufacture (hereinafter «constructions») of a concrete platform, as stated above, in the place of operation the scaffolding, which consistently give fresh concrete, in other words, the fresh concrete is poured.

Known formwork consists of a casing, which is removed after the pouring of concrete (for example, see the patent literature (PL) 1)and the second formwork, which is part of the concrete platform, leave (see for example, patent literature 2).

For example, when a concrete platform constructed using the formwork, described in PL 1 to create the reinforced concrete sleepers, which has a large cross-sectional area of a part of the base plate, the first on-site service scaffolding, pillars supporting formwork, scaffolding, etc, and then fill in with fresh concrete. After the creation of the reinforced concrete cross-beam formwork, support, platforms, etc. removed.

For example, when a concrete platform constructed using the formwork, described in PL 2, in other words, steel formwork, intended for creation of the reinforced concrete cross-beams with a large cross section for part of the base plate, as in the case of DPS 1, the fresh concrete is poured after the first will be installed at the place of operation steel formwork, support, supporting formwork, scaffolding etc

Although after that, these supports, platforms, etc. is removed, the steel formwork not removed, it is part of a concrete platform.

THE ESSENCE OF THE INVENTION

Technical problems

However, as the method described in the above SQ 1, requires formwork and support, scaffolding etc, then there is a problem, which is that the longer the time to create necessary to construct a concrete platform. In particular, the problems that lie in the fact that you install in place formwork and its supports, and then delete them, increases production time. At the same time, since the built-in support plate metal parts must be installed with a given accuracy, the problem arises of additional increase in terms of production.

On the other hand, since the method described in PL 2, used steel formwork made at the factory, you can get a reduction in production time at the place of construction of a concrete platform.

However, when using steel formwork, because steel formwork deformed during pouring of fresh concrete require the installation of additional supports to maintain steel formwork. Consequently, in this case, you first need to install the separate support, and then delete them, which leads to increased time of manufacture.

Because the formwork made of steel, it should be performed at the factory with the need to transport it in a container, respectively, compared with the usual wooden casings increases the cost of transportation and etc.

The data of the invention, a solution of the aforementioned problems, the purpose of this invention is to provide a method to manufacture the concrete platform, which can reduce production time and prevent the increase of costs of the construction, as well as the concrete platform and fastener.

(Solution)

To implement the above mentioned objective of the present invention provides the following solutions.

In accordance with the first aspect of this invention is proposed the method of manufacturing of concrete platform on which to install the object, which contains the create phase formwork with a pair of concrete side walls and the concrete base resting connecting this pair of side panels stage formwork on the set of supports and stage of pouring concrete into a mould, installed on multiple supports.

In accordance with the method of manufacture of a concrete platform on the first aspect of this invention stage of manufacturing of formwork and stage of construction of many bearings can run at the same time, thus, the formwork can be performed at a different location from the location of many supports, in other words, different than that of the construction of a concrete platform. Thus, you can get a reduction of the time of manufacture, i.e. the terms of construction of a concrete platform.

In addition, because the formwork made of concrete, that it need not be removed after the pouring of concrete formwork and, accordingly, production time can be reduced.

On the other hand, when used formwork made of steel plates, then you need to organization of welding works, the formwork at the plant to ensure the accuracy of the sizes. In contrast, if used formwork made of concrete, it eliminates the need for the organization of welding etc. as the formwork can be made in the form of a whole part. So, the location for the manufacturing of formwork is not limited to the plant, the formwork can be made of a suitable location located close to the place of the building, the possible reduction of costs connected with the transportation of formwork.

In addition, as the concrete pouring perform after the installation of formwork with a couple of sides and bottom of the panel on the columns, for installation of formwork can be used crane size is smaller than the way in which the formwork, which filled up with concrete set on columns, or the manner in which a part of the concrete base plate, from which should be removed formwork after pouring the concrete, installed on the columns.

In accordance with the method of manufacture of a concrete platform on the first aspect of this invention during the installation of formwork on many columns, it can be installed on the column after the connection piece, connecting each of the upper boundary parts pairs of lateral wall formwork by its location in the top marginal parts, attached to a pair of side panels.

In accordance with the design at the expense of connection of each of the upper boundary parts pairs of lateral walls of the connecting piece, part of the cross section of the shuttering forms a box-shaped design accordingly, there is a possibility to prevent the lowering of the rigidity of the cross-section of the formwork, due to the expansion of the gap between the marginal parts of the lateral walls (top). Thus, prevents deformation of the formwork during the pouring of concrete, without having to install the pillars of the formwork.

On the other hand, if you are using steel formwork, to prevent the softening of the cross-section of casing on the connected parts between lateral walls and the lower panels can be made elements of rigidity to maintain the relative provisions. However, when stiffening elements, because the internal cross-sectional area (inner space) formwork decreases, the space available for rebar (internal space of the formwork) will be limited.

In this case, in the space of a casing, intended for placing of reinforcing bars, wire rods cannot be located in the bottom panel, in which the current at her bending stress is great. Accordingly, there could be a decrease of strength of a part of the base plate. In the case of concrete casing that is thick compared with steel formwork, the impact is particularly strong. This problem can be solved by connecting each of the parts of the upper edges of the pair of side panels with the help of the proposed fitting.

A method for the manufacture of a concrete platform on the first aspect of this invention mounting part, which is partly embedded in concrete poured into a mould to fix the supported object can be aligned with the connecting element with the possibility of positioning.

In accordance with this design, since the location of the mounting parts supported the connecting piece, you can easily and accurately align the mounting parts without the use of massive plates and temporary support elements that support the specified mounting plate. In addition, terms of manufacturing can be reduced compared with the way in which the fastening parts have directly in the mold with the regulation of their provisions.

In this case, mounting part can have, for example, the metal part that is used to attach the heavy structure, installed on a concrete platform, and may also contain a built-in metal part and etc., for example, anchor bolt.

A method for the manufacture of a concrete platform on the first aspect of this invention connection piece can be removed from the parts of the upper edges of pairs of lateral walls after the stage of concrete pouring.

In accordance with this design has the ability to use the fitting again.

In accordance with the concrete platform on the second aspect of this invention in the manufacture of concrete formwork is not required to remove a timbering, you can reduce the time of manufacture as compared with the case, which is used formwork made of wood and etc

In addition, when using the formwork made of steel it is necessary to organize the welding works, and perform production casing at our factory for dimensional accuracy. In contrast, when you use the formwork made of concrete are not required to arrange for welding etc. Therefore, the location for the manufacturing of formwork is not limited to the plant, and the formwork can be made in a suitable location located close to the place of erection of a structure, reduction of costs connected with the transportation of formwork.

Connection piece, in accordance with the third aspect of this invention is the connecting piece used in the production of a concrete platform according to the present invention, the indicated component contains an elongated part with length essentially the same as the distance between a pair of lateral walls formwork, specifying the part that attaches the fastener to the elongated part, and which part, containing the regulatory part that provides the movement of the fastener along the top surface of a part of the base plate, performed by pouring concrete into the mould.

In accordance with the third aspect of this invention the fitting contains an elongated part, thereby reducing weight. Thus, the fitting can be easily attached to the formwork and detached from it. In addition, when using regulatory provisions of parts and fasteners can be adjusted in two coordinates along the top surface of a part of the base plate, in other words in the horizontal plane.

In accordance with the fourth aspect of this invention offered a concrete platform, containing the top of a base plate with a timbering, part executed in the mold, and the mounting part, moreover: formwork has a U-shaped in cross-section and consists of a pair of concrete side walls and the concrete bottom panel which connects a pair of concrete side walls, and planking is made in such a manner that it removable way attached connection piece, so that the top edges of the concrete side walls are connected to the specified connection piece, which is designed for connection of the upper boundary parts of the concrete side walls for the formation of part by pouring concrete into the formwork and reinforcement elements, passing linearly in the longitudinal direction in the concrete side walls and a concrete bottom.

In accordance with the concrete platform on the fourth aspect of this invention is made design reinforcing elements are located at the sides and bottom panels of the casing, the side walls are connected to the connecting piece. Thus, it is possible to prevent decrease of the rigidity of the formwork. Moreover, since the formwork can be performed in a location separate from the front of the platform, you can reduce the time to manufacture the concrete platform.

The concrete platform in accordance with the fourth aspect of this invention preferably longer contains the item, the length of which is essentially equal to the distance between a pair of lateral wall formwork, and which has the first part of the regulatory which provides introduction of the fastening parts in long detail, and protruding parts, each equipped with the second regulatory part which ensures movement of the fastening parts along the upper surface of the base plate, made by pouring concrete into the mould.

In accordance with this design, you can get the weight reduction of the fitting, it makes it easier for regulation of the position of the fastening parts (built-metal).

In accordance with the fifth aspect of this invention offered formwork used in concrete platform, and the concrete platform, has formwork and part executed formwork, formwork has a U-shaped in cross-section and is a pair of concrete side walls and the concrete bottom of the connecting pair of side panels with formwork made in such a manner that it removable way attached connection piece, so that the top edges of the concrete side walls are connected to the specified connection piece, which is designed for connection of the upper boundary parts of the concrete side walls for the formation of part by pouring concrete into the formwork and reinforcement elements, passing linearly in the longitudinal direction in the concrete side walls and the concrete bottom panel, the fitting contains an elongated part, the length of which is essentially equal to the distance between a pair of concrete side walls of the formwork and regulatory part that provides moving fastening parts along the upper surface of the concrete base plate.

In the mold used in concrete platform in accordance with the fifth aspect of this invention is possible to prevent reduction of rigidity and prevent warping as reinforcing elements are located in the side walls and the bottom of the casing panels and are in connection with the connection plate. Thus there is no need in support, and the construction of a design can be reduced.

(The advantages of this invention)

In accordance with the method of manufacture of a concrete platform, concrete platform and the connecting piece on a given invention is formwork, containing only a pair of concrete side walls and the concrete bottom panel, which connects a pair of side panels, while in the specified formwork after installing it on many columns poured concrete, respectively, the advantages of the invention consist in reducing the production time and in preventing the increase of construction costs.

DESCRIPTION OF EMBODIMENTS

Below is a description of the platform in accordance with the variant of execution of the invention with reference to figure 1-9.

Figure 1 is a schematic view of explaining the configuration of the platform for turbine generators in accordance with this option execution of the present invention.

Platform (concrete platform) 1 is a structure, which is set turbine (steam or gas turbine) and which, in General, is made of concrete and rebar.

In this embodiment, the invention described as used for platform 1 on which establish a turbine generator. However, the specified object, which must be installed on the platform, not limited to a turbine or a generator, it could be another heavy construction, including design, which create a vibration during operation, without restrictions.

As shown in figure 1, platform 1 is mainly performed with numerous columns 2 and base plate 3.

As shown in figure 1, column 2, are the items that are up from the ground G and mostly are made of concrete and rebar to ensure the maintenance of the base plate 3. As columns 2 known designs can be used without restrictions.

As shown in figure 1, part 3 of the base plate is a cross-beam, which is located above the upper ends (the ends of the upper side, figure 1) columns 2, on which establish a turbine generator.

Figure 2 is a cutaway view taken on a line And And explaining the configuration of the base plate, shown in figure 1;

As shown in figures 1 and 2, base plate 3 is most commonly carried out with the formwork 4, part 5, built-in metal parts (fastening parts) 6 etc.

As shown in figure 2, the formwork 4 forms the side surface and the bottom surface of the base plate 3, with part 5, built-in metal part 6 etc. are located in the mold 4. In addition, formwork 4 is made with a U-shaped cross-section, and passes between columns 2.

Formwork 4, basically, is made of concrete and rebar, and, as shown in Fig. 2, makes a single whole with the lower panel 42 and a couple of side walls 41, who pass vertically on both edges of the bottom panel 42. Formwork 4 can have, for example, a width equal to not less than 2 m and a height equal to not less than 2 m

The corresponding side walls 41 have a flat shape and form side surface of the base plate 3, and the lateral surface shuttering 4. The side walls 41 can be, for example, about 150-200 mm sheet thickness, and height of not less than 2 m

The side walls 41, mainly are made with parts 41A side walls of concrete and strained parts of 41 In the side walls.

Concrete part 41A mainly form the side walls 41 of pre-cast concrete which is poured separately from the inside of 51 in part 5.

This variant of performance described for use in the example of a tense part of 41C side walls are located on the top edge side of the parts 41A of the side wall (the side of the top marginal parts, figure 2).

Bottom panel 42 is flat and forms the lower surface of the base plate 3, as well as the lower surface shuttering 4. Bottom panel 42 may be, for example, about 150-200 mm sheet metal thickness and width not less than 2 m

Bottom panel 42 mostly achieved with the bottom of the concrete part of 42A and lower strained parts 42V.

Lower reinforced part of the 42A mainly form the bottom panel 42 of pre-cast concrete which is poured separately from the inside of 51 in part 5.

Lower strained part 42V are the line reinforcing elements, passing in the longitudinal direction of the base plate 3, with lower strained part 42V compress the bottom concrete part of the 42A in the longitudinal direction, because they are located in the lower concrete 42A taut in the above longitudinal direction.

This variant of performance described for use in an example in which the lower strained part 42V are located in one line at regular intervals in the lower concrete 42A.

As the tense parts 41C side walls and stretched parts 42V the bottom panel can be used not limited to known elements, such as wire reinforcing bars etc.

This variant of performance described in the application in the example in which the side walls 41 and the bottom panel 42 forming formwork 4, are made in one piece, but this variant of execution is not limited to the specified form, and performed separately parts can be connected.

part 5 is located in the mold 4 for education base plate 3, together with the formwork 4 provides maintenance of the turbine and the generator, which is installed on the base plate 3.

part 5, largely accomplished with internal concrete plot 51 and reinforcing rods 51.

Inside concrete part 51, mainly forms part 5 and, mainly, perceives force relating to effort among the forces acting on the mounting plate 3. Besides, the internal concrete part of the 51 performed by means of pouring concrete into the formwork 4 separate from the concrete parts 41A side walls and the bottom of the concrete part of the 42A formwork 4.

Internal reinforcing rods 52 represent linear reinforcing elements that pass through part 5 and mainly perceive efforts related to the efforts of stretching among the forces acting on the baseplate. For internal reinforcing rods 52 can be any of the known scheme of location without special restrictions.

As shown in figures 1 and 2, built-in metal part 6 partially integrated into the top surface (surface on the top side figure 1) base plate 3 and are used to attach the turbine and the generator, which should be installed on a base plate 3. Examples of built-in metal parts 6 may include anchor bolts, anchor blocks etc.

Stage of creating the platform 1 (technological process) with the above design will be examined further.

Figure 3 presents a view of explaining the stage of creation of the platform, as shown in figure 1. Figure 4 is a schematic view of explaining the constructive position of the columns shown in figure 1. Figure 5 is a cutaway view, explains the configuration of the formwork, shown in figure 1.

As shown in figure 3 and 4, when creating a platform 1 in accordance with this option, the create phase columns 2 (Stage 1) and, as shown in figure 3 and 5, stage of creation of the formwork 4 (Phase S2) carry out simultaneously.

As shown in figure 4, on the stage of implementation of pillars 2 many columns 2 is carried out on the ground G.

On the other hand, as shown in figure 5, at the execution stage formwork 4 formwork 4, containing a couple of side panels 41 and the bottom panel 42, forming a U-shaped in plan, are made in a location other than the place of construction of platform 1. More specifically, after the execution of concrete sidewalls 41A side walls 41 and bottom concrete 42A concrete bottom panel 42, side strained part 41C and strained part 42V bottom panel accordingly build in a longitudinal tension. Thus, the concrete part of the 41A side walls and the bottom of the concrete part of the 42A impact force in the longitudinal direction.

Thus, for example, even when a part of the base plate is deformed in a downward direction, and tractive force acts on a timbering 4, which forms the lateral surface and lower surface of the base plate, because the pressure of compression pre-applied to the concrete parts of the 41A side walls and the bottom of the concrete part of the 42A, eliminated or reduced the effect of tensile strength.

Done thus formwork 4 transported to the place of construction of columns 2, in other words to the place of construction of platform 1 with the help of a vehicle, such as a trailer.

Figure 6 is a schematic view of explaining the position of the formwork installed on the columns shown in figure 4.

Fig.7 is a view in axonometry, explaining the configuration formwork installed on the columns shown in Fig.6.

As shown in Fig.7, when you install formwork 4 in column 2, the formwork 4 is loaded connecting the upper surface of the item (fitting). Fitting 7 have over parts of the upper edge of the side walls 41 formwork 4 to connect the top marginal parts of pairs of lateral walls 41.

Connection piece, 7 has an elongated part, the length of which is essentially equal to the distance between a pair of lateral walls 41 formwork 4. Connection piece, 7 performed with two 71 holes that take place in the longitudinal direction parts 7 so as to ensure alignment in the longitudinal direction.

In addition, the fitting 7 on the four corners equipped with protruding parts 74, each of which contains a slot of 75, passing in the direction of the width of the fitting 7. Built-in metal part 6, inserted into the holes 71, attach to the fitting 7 nuts 61.

When you attach the fitting 7 part of the casing 4, has a cross-sectional U-shaped forms a box-shaped design, the possibility exists to prevent degradation of stiffness in the cross section due to the expansion of the gap between the marginal parts of the lateral walls (top). Thus, after climbing formwork 4 for installation on many columns 2 and the subsequent placing in it concrete for creating an internal concrete 51, as the gap between the upper edges of the lateral walls of the 41 becomes wider, formwork 4 gets greater resistance to deformation.

Fitting 7 attach to the formwork 4, for example, in the following way.

First item 7 is installed over the top of the boundary of the parts of a pair of lateral walls 41. Next, as shown in Fig.7, in appropriate slotted holes 75 on acting parts 74 insert anchor bolts 73. Then anchor bolts 73 attached to the upper edge parts of pairs of lateral walls 41.

To both sides (both face surfaces in the longitudinal direction) of the fitting 7 attached side panels 72 welding or other connecting way. The attached only part of the upper half of the side panels 72. Accordingly, the lower part of the side panels 72 can hold a pair of lateral walls 41 on both sides. With this method of interaction side panels 72 and anchor bolts prevents the expansion of the gap between the upper edges of the lateral walls of 41.

In the case of steel formwork to prevent softening its cross-section, reinforcing part, to support the relative position of the side walls 41 and the bottom panel 42, may be made at the joints between lateral walls 41 and the bottom panel 42. However, when performing the elements of rigidity of the cross-sectional area of the inner part of the formwork 4, in other words, the internal concrete 51, decreases the space available for accommodation rebar 52 will be limited.

In addition, rebars 52 are located near the bottom panel 42 in the inner part 51, where bending stress is great, there is the possibility of reducing the strength of the base plate. In the case of concrete casing that is thick compared with steel formwork, the impact will be particularly strong.

This problem can be solved by connecting the upper boundary parts pair of side panels with the use of the fitting 7 in accordance with the present invention. If the fitting 7 fastened with installation on top of a pair of lateral walls 41 specified manner, when climbing formwork 4 crane, concrete is poured into a mould 4 for the formation of internal concrete 51 prevented the expansion of the gap between the upper boundary parts of pairs of lateral walls 41.

Fig.8 is a cutaway view, explains the configuration formwork shown in Fig.6, before pouring the internal concrete.

Next, as shown in Fig.8, inside formwork 4 have internal reinforcing rods 52 part 5. Simultaneously, as shown in Fig.7, built-in metal part 6 supported slotted holes 71, made in connecting parts 7, the connection piece, 7 provides positioning of embedded metal parts 6.

Figure 9 is a schematic view of explaining the constructive position of the connecting parts between the columns and formwork.

As shown in figure 3 and 9, stage of creation of connecting parts of the 21 perform after the installation of formwork for columns 2 (Stage S4).

Connecting sections 21 connect column 2, with the formwork 4, in other words, with base plate 3, and connect the two end parts formwork 4 with upper ends of columns 2.

More specifically, this design carry out as follows.

First formwork 4 is loaded into two columns 2 with installing it on the two pillars 2. Then reinforcing rods made inside formwork 4 and reinforcing rods protruding from the upper ends of the columns 2, connect reinforcing rods for the education of the connection. Further, around space, which are reinforcing rods, scaffolding 22.

Then, as shown in Fig. 3, perform step regulation of the provisions of the embedded metal parts 6 (Phase S5). For example, as shown in figure 7, the provisions of subsections (6 govern thereby moving along the slot 71 fitting 7.

In addition, with the weakening of the two anchor bolts 73 can be mixed connective .7 in the direction of its width for precise adjustment. In this case can be made precise adjustment of embedded metal parts 6 two-dimensionally in the horizontal plane.

In this embodiment, despite the fact that shows the design, where the slotted holes 71 pass in the longitudinal direction of the fitting 7, and the slotted holes 75 pass in the direction of the width of the fitting 7, it's also possible design, where the slotted holes 71 pass in the direction of the width of the fitting 7, and the slotted holes 75 are in the longitudinal direction of the fitting 7.

After that, as shown in figure 3, the formwork 4 pour the concrete for the formation of internal concrete 51 and simultaneously also concrete is poured into a mould 22, and then perform a stage of hardening of a concrete Step (S6).

As shown in figure 2, after the pouring of concrete into the formwork 4 to create a concrete 51 inner part of the casing is filled with interior concrete part 51 to create part 5, and lots of metal parts 6 are built into the inner concrete part 51.

Then, during solidification of the cast concrete perform step of removing some scaffolding around the platform 1 (Phase S7), and then remove the fitting 7 with side walls 41, removing anchor bolt 73. Thus, platform 1, as shown in figure 1, is completed.

In accordance with the above design stage of creation of the formwork 4 and stage of construction many columns 2 can run simultaneously, and the formwork 4 can be made at a place other than the location of many of the supports 2, in other words, different than that of the construction of a concrete platform 1. Accordingly, can be achieved reduction of terms of construction, that is, terms of creation of platform 1.

In addition, because the specified formwork 4 is made of concrete, it need not be removed after filling in it concrete and, accordingly, the terms of erection may be reduced.

In addition, when using the formwork made of steel plates, you must perform organization of welding works, as well as produce the formwork at the plant to ensure the accuracy of the sizes. In contrast, if used formwork made of concrete, it eliminates the need for the organization of welding etc. So as a location for manufacturing of formwork is not limited to the plant, the formwork can be made of a suitable location located close to the construction site, the possible reduction of costs connected with the transportation of formwork.

On the other hand, because the concrete pouring for creating an internal concrete 51 do if you have a pair of lateral sides 41 formwork 4 and its bottom panel 42 is installed on the columns, for installation of formwork can be used crane smaller compared to the case in which the formwork 4 is installed on the column 2, after the pouring of concrete for the creation of an internal concrete 51.

By connecting each of the top boundary parts pairs of lateral walls 41 connecting piece 7, part of the cross section of the formwork 4 forms a box-shaped design, and hence there is a possibility to prevent the lowering of the rigidity of the cross-section of formwork 4 due to the expansion of the gap between the marginal parts of the side (top) of the wall. Thus, prevents deformation of the formwork 4 during the pouring of concrete for the creation of an internal concrete 51, without having to install bearings supporting formwork 4.

Because the built-in metal part 6 are held with the slot 71 connecting parts 7, there is a chance of light and high precision alignment metal parts 6 without the use of massive plates and temporary supporting elements, which temporarily support the specified plate on top. In addition, terms of manufacturing can be reduced compared with the way in which built-in metal part 6 is located directly in the mold 4, while providing for the regulation of their provisions.

In addition, as shown in Fig.7, fastener 7 consists of elongated part that provides a reduction in weight. In this connection piece, 7 can be easily attached to the formwork 4 and detached from it. Additionally, because the connection piece 7 is closely regulated by two coordinates in the plane of the section, which forms the upper surface of the part 3 of base plate after pouring the concrete, the provisions of the embedded metal parts 6 can be regulated in two coordinates in the horizontal plane through the specified precisely.

This method of creating a base plate 3 using the above formwork 4 can also be used for the construction of columns 2 without restrictions.
