Description

 . SEAMLESS WALL FORMWORK

The utility model relates to construction and can be used as a fixed formwork for the construction of walls. Known reinforcing block for outdoor oten, including plates interconnected by reinforcing frames, see USSR Patent No. 3 "254, KL.E04S 2 / 24.1969).

Also known is the reinforcing block for external walls, containing internal and external panels with a concrete cavity between them, and a reinforcing mesh is installed between the panels (UK patent No. 1360430, class E04C I / I3, 1974).

The disadvantages of these blocks are the low strength of the connection of concrete slabs to each other, poor joining conditions of reinforcement blocks during the installation of the structure, the block is difficult to assemble, which does not provide accurate control of the thickness of the finished reinforcement blocks.

The closest analogue of the utility model is the reinforcement formwork unit, including reinforced concrete formwork slabs interconnected by rod clamps, and a reinforcing cage (see USSR Author's Certificate No. 1017046, Е04С 2 / 26.1981).

The disadvantage of this design is the inconvenience of installing walls of such blocks. At high consumption of metal and concrete, the required thermal insulation is not provided, v to achieve which it is necessary to use special thermal insulation materials. The objective of the proposed utility model is to increase the rigidity of a fixed formwork block for walls and simplify installation.

for walls consisting of parallel plates interconnected by pins with clamps and a reinforcing cage, the plates on the inside have vertical and horizontal recesses and protrusions forming a key connection, while the clamps connect the plates in the zone of vertical protrusions, at the locations of the clamps with the outside sides of plates installed

vertical metal strips, and the reinforcing cage is made of vertical and horizontal bars, - .-- ..- in the center

sections formed by vertical and horizontal recesses. This allows you to get a rigid, solid wall structure from fixed formwork blocks to absorb the pressure of the concrete mixture during concreting.

The implementation of formwork boards made of expanded polystyrene, as well as the execution of grooves and ridges on the ends of the plates, simplifies the installation process, ensures the speed, ease of assembly of the wall formwork while ensuring the rigidity of the blocks connecting to each other, the strength of the joints formed. Convenience of installation is provided due to the low weight of the blocks, the plates of which are made of 7thirol foam. At the same time, expanded polystyrene plates perform the function of a heater in the wall structure of fixed formwork blocks.

To increase the heat-insulating properties of the wall from the shuttering blocks, the fixers are made of a polymer material of increased strength with a fiberglass base. The removal of fixatives from such a material allows avoiding cold bridges and preserving the thermal insulation properties of formwork blocks and their walls,

Figure 1 shows the formwork block, a General view.

The fixed formwork block for the walls consists of parallel plates I, interconnected by clamps 2, a reinforcing cage 3 made of vertical and horizontal bars. Plates I on the inside have vertical and horizontal recesses and protrusions 5, forming a key connection. Vertical and; j. :: /

located

horizontal rods of the reinforcing cage 3 are located but the center, the sections formed by the vertical and horizontal Byemka i i. At the ends of the threads I, grooves 6 and ridges 7 are made. On the outside of the plates I, at the locations of the clips 2, vertical metal strips 8 are installed, which serve to connect the formwork blocks in height and increase the rigidity of the wall structure of such blocks. Plates I from the outside are made with grooves 9 under the plaster 5, ku. Plates I to increase the fire resistance of blocks and walls of them can be made with cladding.

The assembly of the wall from fixed formwork blocks is as follows. Plates made in advance and the reinforcing cage are installed in a vertical position and connected with clamps, with which they regulate the wall thickness depending on the acting loads; after installing the plates at the required distance, the clamps at the ends are fixed. From non-removable formwork blocks made in this way, the wall is assembled to the height of the floor, fastening the blocks in height with metal strips with holes for retainers, which are installed in the area where the vertical protrusions are located. Then the space between the slabs is concreted. Metal strips, vertically installed to the height of the floor are used to increase the strength of the wall formwork when pouring it with concrete. Due to the execution of slabs on the inner side with vertical and horizontal recesses and protrusions forming a key connection, better adhesion of concrete to the slab surface is ensured, which allows slab formwork slabs to absorb the greater pressure of the concrete mixture during concreting, to increase the load-bearing capacity of the wall with a minimum consumption of concrete.

After the concrete reaches the required strength, a uniform construction of the wall formwork is formed, including the stiffness core.: From reinforced concrete and formwork boards made of polystyrene foam, which simultaneously perform the role of thermal insulation.

 G

Execution from the outside with grooves allows plastering of plates without the use of additional devices, for example, metal mesh, which generally simplifies the technological process of wall decoration.

The use of cladding on the outside of the plates will increase the fire resistance of the block and the stack.

This embodiment of the blocks allows them to be assembled to the height of the floor to obtain a rigid construction of wall formwork, simplify installation, reduce the consumption of concrete and metal, heat-insulating materials for wall insulation.
