Description

The technical field to which the utility model relates.

The utility model relates to underground and ground construction, in particular, to blocks for fixed formwork and can be used in the construction of water-sound-thermal insulation of foundations and walls of civil and industrial buildings and structures.

State of the art

There is a known method of erecting frameless buildings using sliding formwork, which provides for continuous concreting of walls in a system of synchronously moving vertical formwork panels (see T.G. Maklakova, S.N.Nanasova, “Construction of civil buildings.” - M .: Publishing House of the Building Association Universities 2002).

The disadvantages of this method are the danger of “tearing off” the concrete when lifting the formwork (especially concrete on porous aggregates), as well as the low quality of the surfaces of the structure after the formwork, which entails certain costs for the elimination of defects in concrete.

A formwork panel is known, which is a geometric body with side walls and a bottom equipped with stiffeners and provided with holes, while a diaphragm made of elastic porous material with volumetric ornament elements is glued to the bottom of the panel, and the bottom panel is provided with a pallet, the tightness of which is ensured by a gasket, and a fitting for supplying compressed air through the openings in the bottom, entering the gap between the bottom and the lower surface of the diaphragm, and creating excessive pressure in this gap.

In the formwork panel, a diaphragm made of elastic porous material with volumetric ornamental elements is made with through micro-holes communicating with the pallet and glued over the entire surface of the bottom of the formwork panel, and compressed air supplied through the nozzle enters the gap between the diaphragm and concrete, creating excessive pressure in it ( see Pat. RU No. 2296842, IPC E04G 9/10, B28B 7/12, publ. 10.04.2007).

The disadvantage of this formwork panel is the high complexity of its manufacture.

The closest in technical essence and the achieved positive effect and adopted by the author for the prototype is a block for fixed formwork, containing two opposed front and inner plates made of porous insulating material with a facing layer on the outside, fastened with jumpers and forming a space for each other installation of reinforcement and filling with a flowable material capable of solidification, while the plates are made in the form of a rectangular parallelepiped, as the material of the cladding layer on the outer side of the facade plate used material intended for external decoration and not requiring additional processing, as the material of the cladding layer on the outer side of the internal plate used material intended for interior decoration, and the jumpers are made in the form of a parallelepiped of porous heat-insulating material and mounted with a protrusion from the upper and end side surfaces of the plates and their corresponding recesses from the side of the lower counter The front end faces of the slabs.

At least one additional layer is placed in the block for fixed formwork between the plate and the facing layer.

In the block for fixed formwork on the outer side of the inner plate, channels for the installation of utilities are made (see Pat. RU No. 2305158, IPC EV04/86, EV 1/16, publ. August 27, 2007).

The disadvantage of this unit is the complexity of its manufacture, high labor costs.

Utility Model Disclosure

The objective of the proposed utility model is the development of a block for fixed formwork, which has a simplification of manufacturing, high reliability, low cost, saving construction materials.

The technical result that can be obtained using the proposed utility model is to simplify manufacturing, high reliability, low cost of the unit and saving building materials.

The technical result is achieved using a block for fixed formwork, containing two opposite located front and inner plates, fastened with jumpers and forming a space between themselves for mounting reinforcement and filling with material capable of hardening, while the material intended for the facade plate is used for external decoration and not requiring additional processing, and as a material for the outer side of the inner plate used material intended for interior finishes, while the inner sides of the front and inner slabs are provided with transverse stiffeners symmetrically located against each other, while the stiffeners are made integrally with the front and inner plates, and the jumpers are made of welded metal mesh, which is rigidly fixed in the body of the front and inner plates by establishing separate end parts of the mesh in

the internal cavity of the plates while fixing it in the transverse stiffeners.

Thus, the supply of the inner sides of the front and inner slabs of the block for permanent formwork with transverse stiffeners symmetrically located against each other, and the implementation of the lintel from a welded metal mesh, which is rigidly fixed in the body of the facade and inner plates by introducing separate end parts of the mesh into the inner cavity plates with its simultaneous fixing in transverse stiffeners create high reliability during the construction of the foundation, walls, partitions with the possibility of use in the seismic oopasnyh areas with simultaneous cost savings on materials and workmanship.

Utility Model Implementation

The block for fixed formwork consists of two opposite front and inner plates 1, 2, while the inner sides of the front and inner plates 1, 2 are equipped with transverse stiffeners 3, symmetrically located against each other, and plates 1, 2 are fastened with jumpers made of welded metal mesh 4, which is rigidly fixed in the body of the facade and inner plates 1, 2, by introducing the divided end parts 5 of the grid 4 into the inner cavity of the plates 1, 2 with its simultaneous fixing in the transverse ribs 3

rigidity, which creates high reliability in the construction of the foundation, walls, partitions, and the institution of the divided end parts 5 of the grid 4 into the internal cavity of the plates 1, 2, is carried out to the estimated length (see Concrete and reinforced concrete structures. Basic provisions SNiP 52-01 - 2003 Instead of SNiP 2.03.01 - 84), (see Technical Certificate on the suitability of products for use in construction on the territory of the Russian Federation No. TS - 07 - 1694 - 07. Polystyrene foam blocks of fixed formwork. LLC Polystyrene - Stroy, Russia, 620025 , Yekaterinburg, travel Gornistov, 8), and the space between the facade and inner plates 1, 2 serves for mounting reinforcement (not shown in Fig.) And filling with material (not shown in Fig.) Capable of hardening, while as a material for the outer side of the facade plates 1 use a material intended for external decoration and not requiring additional processing, and as a material for the outer side of the inner plate 2 use a material intended for internal decoration.

Block for fixed formwork is operated as follows. In a pre-sized mold with transverse stiffeners 3 provided for the front and inner plates 1, 2, a metal welded mesh 4 is installed by creating separate end parts 5 of the mesh 4 by the calculated length while fixing it in the longitudinal stiffening ribs 3, the thickness being the dimensions, color, texture of the monolithic facade or inner plates 1, 2 and, accordingly, the number of stiffeners 3, as well as the diameter of the welded metal mesh 4 with a cell, depends on the wall thickness and the type of aggregate. For example, in the presented drawings, the block size is 1000 * 500 * 420 mm of a rectangular shape, the thickness of the front and inner slabs is 25 mm, and the mesh f2 with a cell is 50 * 25 mm, then fill in the formed space of the form with various fillers,

capable of hardening, which rigidly fix the welded metal mesh 4 in the body of the facade and inner plates 1, 2 with simultaneous filling and pinching of the mesh 4 in the transverse ribs 3 stiffness.

Blocks arrive at the construction site in finished form. The walls are erected by installing hollow blocks one above the other, connecting with the adhesive and connecting the welded metal mesh 4. Into the space between the front and inner plates 1, 2, fittings are installed and engineering communications are installed, after which the space between the plates 1, 2 fill with a filler capable of solidification, and repeat the process until the design height of the wall is reached.
