The invention relates to the construction, namely the fixed construction formwork, and is intended for the construction of buildings with an attic floor to reduce the cost and accelerate the construction of the building.
When the existence of a great diversity of non-removable formwork using foam for the construction elements of the building, there is a need to develop dinobuton design, allowing to produce elements of the building in the shortest possible time with minimal effort.
The famous "Wall fixed formwork" (patent No. 75861 priority from 13.02.2008)containing a pair of forming surfaces of formwork tiles with embedded elements horizontal communication along the entire formwork contour, and the basis for the formation of the casing includes a pair of formwork and reinforcing tiles and elements of the mortgage, with editions in foamed perlite-concrete solution.
The disadvantage of this permanent formwork are long periods of construction of the building, the required high precision mounting and low maintainability due tiled building design.
Known "Fixed construction formwork" (patent No. 2323308 priority from 24.07.2006), containing soft shell located inside extrusions and filled with a hardening solution.
Fault is m this permanent formwork is the difficulty in mounting and high labor costs in the construction of building elements.
The objective of the invention is to develop a permanent formwork with a simplified design, which is used for construction of buildings with an attic floor.
The technical result of the invention is to reduce installation time, reducing the cost of manufacturing and Assembly work.
The task and the specified technical result is achieved by the fact that non-removable construction formwork contains soft shell, located inside extrusions and filled with a hardening solution, and the soft shell is made in the form of textile sleeves adjacent sleeves sewn to each other with the formation of the cell for a tight location in her guide, made in the form of ribs. While the rib is made or wood, or of plastic, or of metal.
Another option is a fixed construction formwork containing soft shell, located inside extrusions and filled with a hardening solution, and the soft shell is made in the form of textile sleeves adjacent sleeves sewn to each other with the formation of the cell, for dense location in her guide, made in the form of ribs, each rib on both ends equipped with technological hole reference CTE is Zhen, made in the form of a plastic pipe or metal pipe.
The implementation of fixed construction formwork in the form of a woven sleeve, where the neighboring of them flashed with the formation of cells for ribs, made or wood, or of plastic, or of metal, can reduce the cost of construction of the formwork and to simplify the mounting of the casing elements to the process of completing its concrete solution.
And the addition of both extremities of the ribs technological holes rod support in the form of a plastic or metal tube allows for the simplification of the Assembly process of building elements.
The invention is illustrated by drawings, where figure 1 presents the main elements of the fixed casing, and figure 2 is a variant of the ribs.
Fixed construction formwork contains textile sleeve 1 adjacent of which are sewn to each other with the formation of the cell 2, which is the rib 3, and the ribs 3 provided with holes 4, through which will pass the supporting rod 5.
Fixed construction formwork is a textile sleeve 1, which are stitched with each other forming cell 2, while the sleeve 1 can be thus, to achieve a continuous range of thickness in one sleeve 1, thus formed in ACAC is 2, between adjacent sleeves 1, is inserted into the rib 3, which may be made or wood, or of plastic, or of metal. When assembling the formwork due to the support rod 5, the design of stitched sleeve 1 with the ribs 3 is stretched in the horizontal plane to the formation of the wall thickness corresponding to the height of the ribs 3, after which the sleeve 1 are filled with the hardening composition, which, solidify, sformirovyvali bearing wall of the building, the floor slab, Foundation slab, roof and wall partitions, i.e. all elements of the building both vertical and horizontal.
