The INVENTION

Technical issues

However, since the method described in the above PL 1 requires formwork, support, scaffolding, and so on, there is a problem, which is that the extended development time required to build a concrete platform. In particular, the problems lie in the fact that you install in place of the formwork and its supports, and then delete them, thus increasing production time. At the same time, as embedded in the support plate metal parts must be installed with precision, there is the additional problem of increasing the production time.

On the other hand, as in the method described in PL 2, used steel formwork, prefabricated, it is possible to get faster manufacturing on-site facilities concrete platform.

However, when using steel formwork, as the steel casing is deformed during pouring of fresh concrete, the need to install additional supports to maintain the steel formwork. Consequently, in this case, you first need to install a separate support, and then to remove them, which leads to an increase in the time the technology is increasing.

Since this casing is made of steel, it should be performed at the factory with the need of transportation in the container, respectively, when compared with conventional wooden formwork increases the cost of transportation, etc.

This invention offers a solution to the above problems, the aim of this invention is the provision of a method of manufacturing a concrete platform, which is able to reduce the production time and to prevent the increase of costs of the construction, and the concrete platform and the connecting part.

(Solution)

To implement the above objectives of this invention offers the following solutions.

In accordance with the first aspect of the present invention, a method for producing a concrete platform, which must be installed object, comprising the step of creating a casing with a pair of concrete side walls and a concrete bottom panel connecting the specified pair of side walls, the stage of the formwork on the set of supports and a step of pouring concrete into the formwork installed on many supports.

In accordance with the method of manufacturing a concrete platform according to the first aspect of the present invention the stage of manufacture of formwork and construction of a variety of supports can be performed simultaneously, indicated the data formwork can be executed on the spot, other than the location of many poles, in other words, differs from the construction of a concrete platform. Thus, it is possible to obtain a reduction of production time, i.e. terms of construction of concrete platforms.

In addition, because the specified formwork is made of concrete, it need not be removed after pouring concrete into the formwork and, accordingly, the production time can be shortened.

On the other hand, when used as a formwork made of steel plates, it is necessary to complete the organization of the welding operations, and perform the formwork at the factory to ensure dimensional accuracy. In contrast, if you use the formwork is made of concrete, it eliminates the need for welding, etc. as this casing may be made in the form of a part. Thus, the location for the manufacture of formwork is not limited to the plant, the formwork can be made at a suitable location, located close to the building, this may reduce the costs associated with the transportation of formwork.

In addition, as concrete pouring perform after installation of casing with a pair of lateral sides and the bottom panel on the columns, the formwork can be used crane smaller R is smera compared with the method, in which the formwork, which is filled with concrete, set on the columns, or the way in which part of the concrete base plate, from which must be removed formwork after concrete pouring, set up on the columns.

In accordance with the method of manufacturing a concrete platform according to the first aspect of the present invention during installation of the casing at the many columns, it can be installed on the columns after the coupling piece connecting each of the upper edge parts of the pair of side walls of the casing through its location on the upper edge portion attached to a pair of side walls.

In accordance with the specified design by connecting each of the upper edge parts of the pair of side walls connecting piece, part of the cross-section of the casing forms a box-like structure, respectively, it is possible to prevent the lowering of the rigidity of the cross section of the casing, due to the expansion of the gap between the edge parts of the side walls (upper edges). Therefore, prevents deformation of the formwork during concrete pouring, it does not require the installation of bearings supporting the formwork.

On the other hand, if you are using steel formwork, to avoid decreasing the hardness of the cross-section of the casing at the joined parts between b the lateral walls and bottom panels can be executed elements the stiffness to maintain the relative positions. However, the stiffening elements, since the internal cross-sectional area (inner space) of the casing is reduced, the space available for placement of rebar (the inner space of the casing) will be limited.

In this case, in the space of the casing, designed for placing reinforcing bars, reinforcing bars cannot be placed in the lower panel, in which the current on her bending stress is large. Accordingly, this may reduce the strength of the support plate. In the case of concrete formwork, which has a greater thickness compared to steel formwork, the impact is particularly strong. This problem can be solved by connecting each of the upper edges of the pair of side walls using the proposed connection details.

In the method of manufacturing a concrete platform according to the first aspect of the present invention, the fastening part, which is partially embedded in concrete poured into the formwork so as to secure the supported object may be aligned with the connecting element with positioning.

In accordance with this construction, since the location of the mounting parts is supported by the connecting piece, it is possible to easily and Technoservice mounting part without using a separate massive plates and temporary supporting elements, supporting the specified base plate. In addition, the production time can be reduced compared with the method in which the fixing part is fitted directly in the mold with the regulation of their provisions.

In this case, the fastening part may be, for example, a metal piece used to attach heavy design, mounted on a concrete platform, and may also contain a built-in metal parts and so on, for example, the anchor bolt.

In the method of manufacturing a concrete platform according to the first aspect of this invention, the connecting part can be removed from parts of the upper edges of the pair of side walls after the step of pouring concrete.

In accordance with this design it is possible to use the specified connection piece again.

Concrete platform in accordance with the second aspect of the present invention is manufactured by the method for producing a concrete platform according commissioned by the invention.

In accordance with a concrete platform according to the second aspect of the present invention in the manufacture of formwork from concrete is not required to remove the formwork, it is possible to reduce the production time compared with a case that uses a formwork made of wood, etc.

In addition, when using a casing of steel required is to arrange the welding operation, and to complete the fabrication of the casing at the factory to ensure dimensional accuracy. In contrast, when using formwork from concrete is not required to organize welding, etc. Therefore, the location for the manufacture of formwork is not limited to the plant so that the formwork can be made in a suitable location, located close to the place of erection of a structure, this may reduce the costs associated with the transportation of formwork.

The coupling piece in accordance with a third aspect of the present invention is the connecting piece used in the method of manufacturing a concrete platform according to this invention, moreover, the item includes an elongated portion with a length essentially the same as the distance between the pair of side walls of the casing, the locking part that attaches the fastener to an elongated portion, and the protruding portion containing a regulating portion which provides movement of the fasteners along the upper surface of the support plate, performed by pouring concrete into the formwork.

In accordance with a third aspect of the present invention the connecting part includes an elongated portion, thereby reducing weight. Thus, the connecting part can be easily PR is krepline to the formwork and disconnected from it. In addition, when using the regulatory parts of the provisions of the fasteners can be adjusted two-dimensionally along the upper surface of the support plate, in other words, in the horizontal plane.

In accordance with the fourth aspect of the present invention proposed a concrete platform that contains at the upper part of the support plate with the casing and fill the part, made in the casing, and the mounting part, and: the casing has a U-shaped cross section and consists of a pair of concrete side walls and a concrete bottom panel, which connects a pair of concrete side walls, the casing is designed so that it is removable attached the connecting part so that the upper edges of the concrete side walls connected to the specified connection detail used for coupling the upper edge parts of the concrete side walls for forming loaded part by pouring concrete into the formwork, and has reinforcing elements passing linearly in the longitudinal direction in the concrete side walls and a concrete bottom.

In accordance with a concrete platform according to the fourth aspect of the present invention completed the construction in which the reinforcing elements are arranged in the side walls and the bottom of the casing, the side walls connect the tive connecting piece. Thus, it is possible to prevent decrease of the rigidity of the formwork. In addition, since the formwork can be performed in a location separate from the rack platform, it is possible to shorten the manufacturing of concrete platforms.

Concrete platform in accordance with the fourth aspect of the present invention preferably contains an elongated item, the length of which is essentially equal to the distance between a pair of side walls of the casing, and which has a first regulating portion, which provides the introduction of the mounting part in an elongated part, and protruding parts, each of which is provided with a second regulating part to ensure that the movement of the fixing part along the upper surface of the base plate, made by pouring concrete into the formwork.

In accordance with this design it is possible to obtain weight reduction fittings, with easier adjustment of the mounting part (built-in metal).

In accordance with the fifth aspect of the present invention proposed formwork used in concrete platform, and a concrete platform, has formwork and loaded part, made in the formwork, the formwork has a U-shaped cross-section and is a pair of concrete side walls and a concrete bottom panel connecting the pair of side walls, and decking done is on so there is a removable attached the connecting part so that the upper edges of the concrete side walls connected to the specified connection detail used for coupling the upper edge parts of the concrete side walls for forming the loaded part by pouring concrete into the formwork, and has reinforcing elements passing linearly in the longitudinal direction in the concrete side walls and a concrete bottom panel, while the connecting part includes an elongated portion, whose length essentially equal to the distance between a pair of concrete side walls of the casing, and a regulating portion, providing the movement of the fixing part along the upper surface of the concrete base plate.

DESCRIPTION OPTIONS

Below is a description of a platform in accordance with a variant implementation of the present invention with reference to figures 1-9.

Figure 1 is a schematic view explaining the configuration of the platform for a turbo-generator in accordance with this variant implementation of the invention.

Platform (concrete platform) 1 is a facility that installs a turbine (steam or gas turbine) and which is mainly made of concrete and rebar.

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

As shown in figure 1, the platform 1 is mainly made with many columns 2 and base plate 3.

As shown in figure 1, columns 2 are the elements that go up from the ground G and largely completed and the concrete and rebar, providing maintenance support plate 3. As columns 2 can be used a known design without restrictions.

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

Figure 2 is a view in section, taken along the line a-a of explaining the configuration of the support plate shown in figure 1;

As shown in figures 1 and 2, the base plate 3, mainly performed with the casing 4, loaded part 5, built-in metal parts (mounting parts) 6 etc.

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

The casing 4 is mainly made of concrete and rebar, and, as shown in Fig. 2, is integral with the bottom panel 42 and a pair of side walls 41, which pass vertically through both edges of the bottom panel 42. The casing 4 may have, for example, a width equal to not less than 2 m and a height equal to at least 2 m

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

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

The concrete part 41A mainly form the side walls 41 of the pre-filled concrete, which is poured separately from the inner part 51 loaded in part 5.

Strained part 41C are linear reinforcing elements passing in the longitudinal direction of the base plate 3 (the direction perpendicular to the plane of figure 2), this part 41C compress the concrete part 41A in the longitudinal direction, as it is located within parts 41A taut in the above-mentioned longitudinal direction.

This alternative implementation is described for use in the example in which the strained part 41C side walls are located on the upper edge side portions 41A of the side wall (side wall upper edge portion, figure 2).

The bottom panel 42 is planar and forms a bottom surface of the base plate 3 and the lower surface of the casing 4. The bottom panel 42 may be, for example, about 150-200 mm sheet thickness and width not less than 2 m

The bottom panel 42 is mainly carried out from the bottom of the concrete part 42A and the lower nut is other parts of 42V.

The lower concrete portion 42A mainly form the bottom panel 42 of the pre-filled concrete, which is poured separately from the inner part 51 loaded in part 5.

Bottom-stretched part 42V represent linear reinforcing elements passing in the longitudinal direction of the base plate 3, the lower-stretched part 42V compress the lower concrete portion 42 in the longitudinal direction, since they are located inside the lower concrete portion 42A taut in the above-mentioned longitudinal direction.

This alternative implementation is described for use in the example, in which a strained lower part 42 are arranged in a line at equal intervals in the lower concrete portion 42A.

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

This alternative implementation is described for use in the example in which the side walls 41 and bottom 42, forming the casing 4, made in one piece, but this variant execution is not limited to this specific form, and executed separately parts can be connected.

Load the part 5 is located in the casing 4 for the formation of the support plate 3, together with the casing 4 and provides maintenance curb the us or generator, which are mounted on the base plate 3.

Loaded part 5 mainly made with concrete inner section 51 and the reinforcing rods 51.

The inner concrete portion 51, mainly forms the loaded part 5 and, mainly, perceived stress related to compressive force among forces acting on the support plate 3. In addition, the inner concrete portion 51 is performed by pouring concrete into the formwork 4 separately from the concrete parts of the side walls 41A and the lower concrete portion 42A of the casing 4.

Internal reinforcing rods 52 are linear reinforcing elements, which pass through the loading part 5 and, mainly, perceive efforts related to the efforts of tension among the forces acting on the support plate. For internal reinforcing rods 52 may be any known layout without special restrictions.

As shown in figures 1 and 2, the embedded metal parts 6 are partially embedded in the upper surface (surface on the upper side, figure 1) base plate 3 and are used to attach the turbine or generator, which must be installed on the baseplate 3. Examples of embedded metal parts 6 may include anchor bolts, anchor blocks, etc.

Creation platform 1 (technological process) above the design will be considered in the future.

Figure 3 is a view explaining the step of creating the platform shown in figure 1. Figure 4 is a schematic view explaining the constructive position of the columns, shown in figure 1. Figure 5 is a view in sectional view explaining the configuration of the casing shown in figure 1.

As shown in figure 3 and 4, when the platform 1 according to this variant, the step of creating columns 2 (Step S1) and, as shown in figure 3 and 5, the step of creating the formwork 4 (Step S2) is performed at the same time.

As shown in figure 4, at the stage of execution of columns 2 many columns 2 perform on the ground G.

On the other hand, as shown in figure 5, at the stage of execution of the casing 4 casing 4 containing a pair of side walls 41 and bottom 42, forming a U-shape, is made in another place than the place of construction of the platform 1. More specifically, after performing concrete lateral parts 41A of the side walls 41 and the lower concrete portion 42A of the concrete bottom panel 42, the side-stretched part 41C and the strained portion 42 of the bottom panel respectively inserted into the longitudinally stretched. Thus, on the concrete part of the side walls 41A and the lower concrete portion 42A has an impact force of compression in the longitudinal direction.

Thus, for example, even when a portion of the support plate is deformed in a downward direction, and to grow evasee force acts on the casing 4, which forms side surfaces and the bottom surface of the base plate, because the voltage of the pre-compression is applied to the concrete parts of the side walls 41A and the lower concrete portion 42A, eliminates or reduces the effect of tensile strength.

Designed so the casing 4 are transported to the construction site of the columns 2, in other words to place the construction of the platform 1 with the help of a vehicle such as a trailer.

6 is a schematic view explaining the position of the casing mounted on the column, shown in figure 4.

After transportation of the casing 4 to the place of construction of the platform 1 perform the installation phase of the casing 4 on the column 2, as shown in figure 3 and 6 (Step S3).

Fig.7 is a perspective view explaining the configuration of a casing mounted on the column, shown in Fig.6.

As shown in Fig.7, when installing the casing 4 in column 2 on the casing 4 is placed connecting the upper surface part (connecting part). The connecting part 7 is fitted over the upper edge of the side wall 41 of the casing 4 so as to connect the top edges of a pair of side walls 41.

Connection piece 7 has an elongated portion, whose length essentially equal to the distance between a pair of side walls 41 of the casing 4. Connection piece 7 is Ipanema with two slotted holes 71 which are in the longitudinal direction of the workpiece 7 so as to provide alignment in the longitudinal direction.

In addition, the coupling piece 7 at the four corners provided with protruding parts 74, each of which contains a slot 75, passing in the direction of the width of the connecting part 7. Embedded metal parts 6, inserted into the holes 71, attached to the connecting part 7 by nuts 61.

When attaching the connecting part 7 part of the casing 4, having in cross section U-shaped, forms a box-like structure, it is also possible to prevent the lowering of the rigidity in the cross section, due to the expansion of the gap between the edge parts of the side walls (upper edges). Thus, after the lifting of the casing 4 for installation on multiple columns 2 and then filled with concrete to create the inner concrete portion 51, since the gap between the upper edges of the side walls 41 becomes wider, the casing 4 becomes greater resistance to deformation.

Connection piece 7 is attached to the casing 4, for example, by the following method.

First, item 7 is installed over the upper edge parts of the pair of side walls 41. Next, as shown in Fig.7, in the corresponding slotted holes 75 on the protruding parts 74 insert anchor bolts 73. Then anchor bolts 73 are attached to the upper edge parts of the pair of side walls 41.

To both side surface the values (both end surfaces in the longitudinal direction) of the connecting part 7 is attached the side panels 72 by welding or other connecting means. When this is attached only to the upper half of the side panels 72. Accordingly, the lower part of the side panels 72 can hold a pair of side walls 41 on both sides. In this way, the interaction of the side panels 72 and anchor bolts prevents widening of the gap between the upper edges of the side walls 41.

In the case of steel shuttering to prevent reduction of the rigidity of its cross-section, the reinforcing part that supports the relative position of the side wall 41 and the bottom panel 42 may be made at the joints between side walls 41 and the bottom panel 42. However, when elements of the stiffness of the cross-sectional area of the inner part of the casing 4, in other words, the inner concrete portion 51 is reduced, while the space available for placing reinforcing bars 52 will be limited.

In addition, the reinforcing bars 52 will be located near the bottom panel 42 in the inner part 51, where the bending stress is large, accordingly, there is a possibility of reducing the strength of the base plate. In the case of concrete formwork, which has a greater thickness compared to steel formwork, the impact will be particularly strong.

This problem can be solved by connecting the upper edge parts of the pair of side walls with connective on the hoist 7 in accordance with this invention. If the fitting 7 is attached with the installation on top of a pair of side walls 41 in this way, when lifting the casing 4 with a crane and pouring concrete into the formwork 4 for the formation of the inner concrete portion 51 is prevented from extending between the top edge parts of the pair of side walls 41.

Fig is a view in sectional view explaining the configuration of the casing, shown in Fig.6, before pouring the internal concrete.

Next, as shown Fig, inside the casing 4 with an inner reinforcing rods 52 loaded part 5. At the same time, as shown in Fig.7, built-in metal parts 6 are supported in slotted holes 71, is made in the connecting part 7, while the connecting part 7 provides for the positioning of the embedded metal parts 6.

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

As shown in figure 3 and 9, the step of creating the connecting parts 21 perform after installing formwork for columns 2 (Step S4).

The connecting sections 21 connect the column 2 with the casing 4, in other words, the support plate 3, and connect the two end parts of the casing 4 with the upper ends of the columns 2.

More specifically, this design perform the following the way.

First, the casing 4 is placed on two columns with 2 installing it on two columns 2. Then reinforcing rods made inside the casing 4 and the reinforcing rods protruding from the upper ends of the columns 2, connect the reinforcing rods for the education connection. Further, around the space where the reinforcing rods, install the casing 22.

Then, as shown in Fig. 3 perform the step of regulating the provisions of the embedded metal parts 6 (Step S5). For example, as shown in Fig.7, the provisions of parts 6 regulate, thereby moving along the slot 71 of the connecting part 7.

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

In this embodiment, although the illustrated construction, in which the slotted holes 71 are held in the longitudinal direction of the connecting part 7 and the slotted holes 75 are in the direction of the width of the connecting part 7, it is also possible to design, in which the slotted holes 71 are held in the direction of the width of the connecting part 7 and the slotted holes 75 are held in the longitudinal direction and join the compulsory part 7.

After that, as shown in figure 3, the casing 4 pour the concrete for the formation of the inner concrete portion 51 and at the same time the concrete is poured into the casing 22, and then perform the step of hardening concrete (Step S6).

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

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

In accordance with the above construction phase of the development casing 4 and the construction of many columns 2 can be performed simultaneously, the casing 4 may be performed at a location different from the location of many of the supports 2, in other words, differs from the construction of a concrete platform 1. Respectively, can be achieved by reducing construction time, that is, the timing of the creation of the platform 1.

In addition, as the above-mentioned casing 4 is made of concrete, it need not be removed after being filled with concrete and, according to the government, the construction time can be shortened.

In addition, when using a casing made of steel plates, you must follow the organization of welding, and also to produce the formwork at the factory to ensure dimensional accuracy. In contrast, if you use the formwork is made of concrete, it eliminates the need for welding, etc. Thus, the location for the manufacture of formwork is not limited to the plant, the formwork can be made at a suitable location, located close to the construction site, thus possibly reducing the costs associated with the transportation of formwork.

On the other hand, since the concrete is poured to create the inner concrete portion 51 do if you have a pair of lateral sides 41 of the casing 4 and the lower panel 42 is installed on the columns, the formwork can be used crane smaller compared with the case in which the casing 4 is installed on the column 2 after pouring concrete to create the inner concrete portion 51.

By connecting each of the upper edge parts of the pair of side walls 41 of the connecting part 7, part of the cross-section of the casing 4 forms a box-like structure, respectively, it is possible to prevent the ratite lowering of the rigidity of the cross section of the casing 4, due to the expansion of the gap between the edge parts of the side (top) of the wall. Therefore, prevents deformation of the casing 4 during pouring of the concrete to create the inner concrete portion 51, it does not require the installation of bearings supporting the formwork 4.

Because the embedded metal parts 6 are held through slot 71 of the connecting part 7, there is a possibility of easy and high-precision alignment of metal parts 6 without using a separate massive plates and temporary supporting elements, which temporarily support the specified stove top. In addition, the production time can be reduced compared with the way in which embedded metal parts 6 are located directly in the casing 4, while ensuring the regulation of their provisions.

In addition, as shown in Fig.7, the connecting part 7 consists of an elongated part that provides weight reduction. In this connection piece 7 can be easily attached to the casing 4 and is disconnected from it. Additionally, since the connecting part 7 is closely regulated by two coordinates in the plane of the portion which forms the upper surface portion 3 of the base plate after pouring of the concrete, that the provisions of the embedded metal parts 6 can R guluronate two-dimensionally in a horizontal plane by means of the fine adjustment.

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