The present invention relates in General to insulating formwork for concreting the walls of the building structure, and more particularly to a mold formed by the side walls of foamed polystyrene, between which are formed channels, and in which is placed the concrete in the form of liquid cement grout, causing it to become part of the permanent wall structure.

For several decades it is known the use of insulating formwork for concreting of the walls of building structures as a means of eliminating the use of metal or wooden formwork for erecting concrete walls of the buildings on the construction site. Although metal or wooden formwork are reliable tools for the manufacture of wall constructions, they have a disadvantage in that the formwork cumbersome and inconvenient for use, and must be removed after sufficient hardening of the concrete, it is necessary to provide the possibility of their removal until they become permanently part of the wall structure. It is a labour intensive process and, in particular, leads to the fact that a significant part of the cost of labour on the construction site due to the installation of formwork for concrete placement.

Currently known insulating concrete formwork straw is positive structures used foamed polystyrene, and these designs fall into two main categories: block type and a sheet type. In the construction of a block of type using a molded building block elements of foamed polystyrene, which place with the formation of the building blocks to obtain concrete walls. Design of block type easy to use, but for their Assembly on the construction site requires significant effort. Blocks typically include internal clamps or brackets that are designed to increase strength and connections between the blocks. One of the principal disadvantages of block type lies in the fact that they are difficult to perform the openings for Windows or doors, and this limits their practical application for erection of major wall structures, such as garages. One example of the construction block of the type disclosed in U.S. patent No. 5465542, and this design differs from the usual block designs the fact that in the considered blocks have built-in mounting rails for fixing decorative wall coverings.

In the construction of sheet-type use two molded sheet of expanded polystyrene, one sheet on each side of the formwork. Usually the sheets are held at a distance by a set of clamps or brackets that need to recognize is taken at the construction site and are bulky, and also require a large number of working operations. Developed numerous methods of sealing joints between sheet structures, but they also demand more labor. Not exist leaf design that makes it easy to place Windows or doors, which again leads to an increase in work at the construction site. Another main drawback of these two competitive designs stems from the fact that they cement can not be fixed without additional reinforcement (external formwork or support forests), necessary to prevent breakthrough of the cement through the casing during its installation. An example of a design sheet of the type disclosed in U.S. patent No. 3788020, and in one embodiment, it includes a pair of spaced apart for a distance of panels connected to each other fireproof stretch marks.

Although known insulating concrete formwork design have many disadvantages, they gained recognition in the industry because they contribute to energy saving and comfort in the building. To use competitive construction convince their energy efficiency. In addition, building codes and regulations require insulation basement and Foundation walls. Therefore, in practice, insulating concrete formwork constructions are OS the fight recognised as designs for the construction of the basement and Foundation walls, despite the fact that they do not create savings in labor costs compared to conventional construction methods. However, their recognition by major contractors or developers still significantly limited.

The present invention is the creation of insulating concrete formwork building construction that requires significantly less labor on the construction site, and provided design, which is easy to run Windows and doors.

According to the first variant implementation of the present invention is designed insulating formwork for concreting of the walls of building structures comprising spaced, elongated side walls of foamed polystyrene having opposite inner surface formed with spaced along the length of the vertically directed ribs which terminate essentially flat surfaces adjacent each other to form forms for concrete walls.

Located at a distance of ribs form channels for the placement of concrete casting. It is preferable to form the polystyrene side walls by cutting a single sheet of foamed polystyrene into two generally equal parts. Preferably, the top and bottom edges of the side walls have upper and lower ends, to the which are located at a distance from the edges of the side walls, for education between the side walls of the upper and lower zones for the reception of concrete, is in communication with the channels between the ribs. For the formation of the openings for Windows and doors edges of the side walls are torn areas to accommodate the locking elements, which are located between the side walls, while the locking elements are made in the form of an aperture of the desired window or door.

According to the second variant of implementation of the present invention is designed insulating formwork for concreting of the walls of building structures comprising spaced, elongated side walls of foamed polystyrene with a spacer elements located between the side walls. Each dividing element comprises upper and lower surface and two flat sides, one of which is attached to one side wall and the other attached to the second side wall. Separation elements spaced distances along the length of throughout the side walls, so that between the separating elements are formed channels. The upper and lower surfaces of the separating elements are arranged at a distance from the upper and lower edges of the side walls for education between the side walls of the upper and lower zones for the reception of concrete, which communicate with the channels between the separation ale is nami. For the formation of the openings for Windows and doors separating the elements cut out and attach to the first side wall so that the bearing surface is obtained in the form of the desired window or door. In the bearing surface enter the latch and attach the second side wall.

According to the third variant of implementation of the developed insulating concrete wall construction, including formwork, which is molded in a single piece to obtain a construction somewhat similar to the design of the first and second embodiments, when they are collected. However, due to the fact that the Assembly of the formwork is not required, this option is even more economical labor costs.

Plastic protective layer can be applied on the outer surface of one or both side walls of the present invention, which eliminates the need for a finishing layer and creates a barrier to moisture, rodents and many insects. This is particularly advisable when the casing is used on the soil Foundation. Preferably, this plastic protective layer was made from a sheet of a copolymer of Acrylonitrile, butadiene and styrene thickness of about 1/16 inch.

The above and other advantages of the present invention will become apparent from the following description. In the description made ssy is key to the accompanying drawings, which are part thereof, and in which is shown for illustration only, without limiting them to specific embodiments of the invention.

The proposed national improvements is consistent insulating formwork for concreting of the walls of building structures, which is better to use in construction as a means for fast and efficient construction of private foundations, basements and ground concrete walls in a manner that excluded significant work on the construction site, and dramatically reduces the time of construction and completion on the construction site. The design of the present invention provides greater flexibility than is available currently in the insulating formwork for concrete structures based on blocks or sheets, and applicable for interior and exterior basement, ground and multi-storey buildings.

Figure 1 shows the first preferred implementation of the insulating formwork for concrete walls of the building structure, generally designated position 10. Specialists in the art should understand that in the shown embodiment, only one section of the whole structure, all of the sections are structurally identical, except for those sections, which may be a door or window. Structure 10 forms a casing which is mounted on the upper part of the base plate 11 of the conventional type and includes a pair of elongated side walls 12 and 13 of foamed polystyrene. Located at a distance of steel corners of the 14 attached to the plate 11 at the base of each of the side walls 12 and 13 to hold them in place relative to the plate 11.

As shown in figures 2 and 3, the side wall 16 can be used as the side wall 13 and side wall 14. Side wall 16 has an outer surface 17 (shown only in figure 3) and the inner surface 18, provided with spaced along the length pointing straight edges 19, which protrude outwards from the inner surface 18. As shown in figure 2, the ribs 19 are top and bottom ends 20 and 21 respectively, which are related to the distance from the top and bottom edges 22 and 23 respectively of the side wall 16. As best shown in figure 3, each of the ribs 19 are formed at least three sides, i.e. with two inclined side portions 24 which terminate at the outer flat surface 25 forming channels 26 between the ribs 19, which form a mirror image of the ribs 19 so that the two side walls 16 can be cut hot wire from a single sheet of foamed polystyrene, as well as to provide increased structural strength 10. Preferably, the side edges 27 and 28 of the side wall 16 is formed as mutually conjugate with the adjacent side wall 16. Lateral edge 27 has a narrow ledge 29 and the lateral edge 29 has a shelf 30, the size of which is usually equal to the amount of protrusion 29. In addition, it is preferable that the outer surface 17 of the side wall had a lot fo the data vertically, located in the grooves Breslin 31, which after the design of insulating concrete wall is completed, can be used for attaching finishing materials to the side wall 16.

Figure 4 shows the side walls 12 and 13, spaced relation to each other so that the flat surface 25 of their ribs 19 are adjacent to each other, performing the function of the spacers between the side walls. In this case, the channels 26 between the ribs 19 to form a closed space for placement of concrete, which have a hexagonal shape. In this form reduces the compression of the ribs 19, when the compressive force is applied to the side walls 12 and 13, due to the reduced width of the dividers in the middle between them. In addition, as shown only in figure 5, due to the fact that the upper ends 20 and the lower ends of the ribs 21 is related to the distance from the top and bottom edges 22 and 23 respectively of the side walls, are formed upper and lower zones 32 and 33, respectively, for the reception of concrete, which communicate with the channels 26 between the ribs 19.

To increase the structural strength of the wall formed with the aid of formwork construction 10, the inside of the channels 26 have rods or reinforcing bars 35 (figures 4, 6 and 7), securing them by means of snap-on rebar centering clamps 36, best shown in figuro, 9 and 10. The clamp 36 is made relatively thin and rectangular in shape with a Central cut out portion 37, which forms two tabs 38 for securing the clamp to the reinforcing rod 35, as shown in Fig.9. Preferably, the clamp 35 is formed from semi-rigid plastic that can be bent to accommodate the rebar 35, but strong enough to hold the rebar in the right place, placed in the center of the channel 26. Through the use of clamps 36 rebar can quickly and effectively be positioned as desired within the channel 26.

The use of side walls 12 and 13 allows you to get strong and durable insulating wall which is formed without Windows and doors. As shown in figures 11 and 12, to create Windows or doors in the structures obtained with the aid of formwork construction 10, the side wall 42 is used in conjunction with the spacer 43. The side wall 42 is different from the side walls 12 and 13 so that the parts of the edges 19 of the side wall 42 removed for the formation of the supporting surface 44 of rectangular shape corresponding to the shape of the window opening, which must be obtained by using the side wall 42. For example, the side wall 42 is designed to form a wall with a window. After the sections of the ribs 19 are removed for the formation of the reference surface is rnost 44, in the side wall 42 installing the latch 43 to prevent inflow of concrete inside remote areas of the ribs 19 and the channels 26 between them. After the formation and solidification structure of the wall you can cut the opening occupied by the latch 43, which is preferably formed of polystyrene.

Therefore, formwork construction 10 of the present invention can be successfully used for fast and efficient education insulating walls. It is preferable to perform basic operations, including the manufacture of formwork design 10, outside of the construction site. For example, the side walls 12 and 13 specific forms that are required for the appropriate Windows or doors, can be easily made by cutting a single sheet of polystyrene using a heated wire. Two side walls formed by cutting, and then, if necessary, stick together with each other throughout the spacers Windows or doors, and the location of doors and Windows represent the side walls. Then assembled formwork delivered to the construction site for use.

The structure 10 can be made moisture-proof, resistant to insects and rodents by layering plastic sheet on the outer surface of the side wall, which should be the outer side of the house. Predpochtitel is but to this layered sheet was made from a copolymer of Acrylonitrile, butadiene and styrene and has a thickness of approximately 1/16 inch. It can also be combined with design outside construction site.

On Fig shows a second preferred implementation of the insulating formwork for concrete walls of the building structure, generally indicated by the position 60. Specialists in the art should understand that in the shown embodiment, only one section of the whole structure, while the sections are structurally identical, except for those that may have a door or window. Design 60 forms a shape which is mounted on the upper part of the base plate 62 of a standard type, and includes a pair of elongated side walls 64 and 66 of foamed polystyrene, each of which has an inner surface 68, 70, the outer surface 72, an upper edge 74, 76 and the lower edge 78, 80, and side edges 82, 84. Posted on length steel corners 86 attached to the plate 62 at the lower ends 78, 80 of the side walls 64 and 66 to hold them in place relative to the plate 62.

As shown in figures 14 and 15, two side walls 64 and 66 separated directed vertically dividing elements 90, which have two flat sides 92 and 94, 96 in mid transverse to the cross section and the upper and lower ends 98 and 100, respectively, which are related to the distance from the top edges 74 and 76 and the lower edges 78 and 80 of the side walls 64 and 66. Each of the dividing element 90 is formed so that the flat sides 92 and 94 is wider than the middle of the 96. When spaced along the length of the spacer elements 90 are attached to the inner surfaces 68 and 70 of the side walls 64 and 66, between the separation elements 90 are formed channels 106. Preferably, these channels 106 had a hexagonal shape. Spacer elements 90, is placed along the side walls 64 and 66 and which is closest to the side edge 82 or 84 of the side wall 64 or 66, made in the form of symmetrical halves of the dividing elements are separated along the vertical axis directed transversely of the planes of the side walls, forming a third flat side 110. One half of the separation element 108 feature so that the third flat surface 110 extends beyond one of the side edges 84 of the side walls 64 and 66, respectively, and the other is located just inside the side edges 82 of the side walls 64 and 66 of the structure 60. As best shown in Fig, when such arrangement is formed layout to match the side walls 64 and 66 adjacent structures 60. In addition, it is preferable that the outer surface 72 of the side wall included many visit the military at a distance, placed in the grooves Breslin 112, which after the design of insulating concrete wall is completed, can be used for attaching finishing materials to the side walls 64 and 66.

As shown in figures 15, 16 and 17 to form a window or door in the structures obtained via structure 60, cut out parts of the dividing element 90, and the remaining part is used in conjunction with the latch 122. Surviving separation elements 90 are attached to the first side wall 64, using this method of fastening, as gluing, so that a bearing surface 124 of rectangular shape corresponding to the shape of the window opening. Then in the bearing surface 124 sets the latch 122 and the remaining side wall 66 fasten with separating elements 90, using a similar method of attachment. After the formation and solidification structure of the wall you can cut the opening occupied by the latch 122, which is made from polystyrene, which is preferable.

Preferably, a large part of business operations in the manufacture of formwork structure 60 has run out of the construction site. For example, you can make openings for doors or Windows in the separation elements 90, then dividing elements 90 can be set into position and glued to the first side of the article is the NCA 64, accordingly to accommodate the latch 122 and then to glue the spacer elements 90 to the second side wall 66. The location of doors and Windows indicate on the outside of the side walls and then assembled formwork delivered to the construction site for use.

When concrete is placed in the casing 60, he will fill the channels 106. Due to the fact that the upper ends 98 and the lower ends 100 of the dividing element 90 is related to the distance from the top edges 74, 76 and bottom edges 78, 80 of the side walls 64 and 66, are formed respectively in upper and lower zones 130 and 132 for receiving concrete, communicating with the channels 106.

As previously described and shown in figures 4 to 10, increasing the structural strength of the wall is provided formwork design 60, rods or reinforcing bars located inside the channels 106.

Formwork structure 60 can be made moisture-proof, resistant to insects and rodents by layering sheet 136 of plastic on the outer surface 72 of the side wall 64, which should be the outer side of the house. Preferably, this layered sheet was made from a copolymer of Acrylonitrile, butadiene and styrene and has a thickness of approximately 1/16 inch.

As described above, the casing formed by the structures 10 and 60, is designed to produce in the form of parts and subsequent Assembly, preferably by gluing. However, such manufacturing of these forms is not a feature of the present invention, since it is assumed that the formwork, which is within the scope and essence of the present invention can be formed by molding or by extrusion to obtain made in one piece casing, which does not need to be collected.

In figures 18-20 shows the third preferred implementation of the present invention. On Fig pictured is made in one piece of insulating formwork for concreting of the walls of the building structure indicated by the position 140. Exactly the same as in the first and second embodiments, implementation, design 140 forms a casing which is mounted on the upper part of the base plate 162 of the standard type and includes a pair of elongated side walls 164 and 166 of foamed polystyrene, each of which has an inner surface 168, 170, the outer surface 172, an upper edge 174, 176 and the bottom edge 178, 180 and the side edges 182, 184. Located at a distance of steel corners 186 attached to the plate 162 on the lower edges 178, 180 of the side walls 164, 166 to hold them in place relative to the plate 162.

As shown in figures 18 and 19, two side walls 164 and 166 are separated made in one piece, directed vertically dividing elements 10, which act as spacers between the side walls 164 and 166. Each element 190 has a cross-section of mid-196 (see Fig) and the upper and lower ends 198 and 200, respectively (Fig), which are related to the distance from the top edges 174 and 176 and the lower edges 178 and 180 of the side walls 164 and 166, respectively. In addition, each of the separating elements 190 are designed so that in cross section has a maximum width in the middle of 196. Separation elements 190 spaced distances along the length, so that the separation between elements 190 are formed channels 206 (Fig). Preferably, these channels had a hexagonal shape with a narrow gap between them, which prevents the compression of the casing 160, when the compressive force is applied to any one or both side walls 164 and 166.

When concrete is placed in the design 160, he will fill the channels 206 with the formation of the vertical pillars. The upper and lower ends 198 and 200 respectively dividing elements 190 attributed to the distance from the top edges 174, 176 and bottom edges 178, 180 of the side walls 164 and 166, which are formed respectively in upper and lower zone 230 for receiving concrete, communicating with the channels 206. Preferably, the upper and lower ends 198 and 200, respectively, the separating element 190 includes a transverse channels 234 and 236, the cat is who performs the function of hardening such ends. Therefore, the design 160 forms formwork, which is structurally similar to the casing formed by the structures 10 and 60, except that it does not need to be collected.
