Description

The proposed utility model relates to the field of construction of walls of buildings and structures for residential, social and domestic and industrial purposes from block building material.

From the prior art, the solution RU 2480566 C2 is known, which discloses a formwork containing external and internal removable formwork panels, between which a heat-insulating layer is installed at a predetermined distance from them, with the formation of a cavity for pouring concrete of the internal and external walls. Sheets of plywood and plastic can be used as formwork panels.

This solution has significant drawbacks, namely, the installed metal spacers are sources of condensation, and after removing the formwork panels, metal spacers remain visible on the outer wall, which in turn prevents the creation of a final texture of the outer wall at the stage of concrete pouring.

The declared utility model is based on the task of eliminating the indicated disadvantages.

The technical result of the claimed utility model is the elimination of condensation from the fastening element in the wall.

This technical result is achieved by the fact that the formwork block containing the inner shuttering board and the outer shuttering board, between which a heat-insulating layer is installed at a given distance, with the formation of cavities for pouring the hardening solution to form the inner and outer walls, while the iron pins, not reaching formwork panels, penetrate the heat-insulating layer and are fixed on it from opposite sides by fixing elements, and from the side directed to the inner formwork panel, each stud includes a plastic dowel, into which a temporary bolt is installed through the internal formwork panel, while the inner and outer formwork panels along the upper side through the threaded lug are connected to each other by an adjusting pin with threads applied to it from opposite sides in different directions.

It is desirable that the inner formwork panel is a sheet of film faced plywood.

It is desirable that the external formwork panel is a sheet of plastic removable formwork.

Optionally, the outer formwork panel has a groove connection along the entire perimeter of the panel for fastening to the adjacent formwork panel.

It is desirable that a reinforcing cage and a reinforcing mesh are installed in the cavities formed for pouring.

In addition to the inner side of the outer formwork panel, cladding inserts can be installed.

Consider the proposed solution in more detail, taking into account the drawings.

The formwork block contains:

1 - Temporary bolt

2 - Internal formwork panel

3 - Plastic dowel

4, 8 - Hardening solution

4.1 - Reinforcement cage

5 - Iron hairpin

6 - Fixing elements

7 - heat-insulating layer

9 - Reinforcing mesh

10 - External formwork panel

The shuttering block comprises an inner shuttering board 2, which is a removable sheet of preferably laminated plywood, and an outer shuttering board 10, which is a sheet of preferably plastic removable casing. The shield 10 has a certain texture on the inside to form a volumetric image and / or texture on the hardening mortar 8. Between these formwork blocks, at a given distance from them, an insulating layer 7 is installed, with the formation of cavities for pouring the hardening solution 4, 8 to form inner and outer walls. The thermal insulation layer can be various options for solid insulation, for example, extruded polystyrene foam and foam; hard mineral wool with a density of more than 35 kg / m³; foam glass; polymer concrete; sandwich panels; insulated wall panels, etc. The size of the formed cavities is selected depending on a number of factors, for example, the thickness of the wall, the size of the insulation, the height of the building, etc. Each of the iron studs 5, before reaching the shuttering boards, penetrates the thermal insulation layer 7 and is fixed on it with opposite sides with locking elements 6. As locking elements 6, for example, washers and nuts are used. The fixing elements 6 move along the hairpin 5 to increase or decrease the thickness of both the inner and outer walls, and the thickness of the heat-insulating layer, under each object, and also fix the reinforcing mesh 9 at the required distance between the insulation 7 and the outer formwork shield 10. Reinforcement frame 4.1 and reinforcing mesh 9 are used to increase the ability of the hardening mortar to accept the “bending” load. As a hardening mortar 4, 8, a concrete mixture, sand-cement, glass-cement, polystyrene-cement, etc. is used.From the side directed to the inner formwork shield 2, each stud 5 is fixed with a plastic dowel 3, into which through the inner formwork shield 2 a temporary bolt 1 is installed. This bolt 1 holds the formwork shield 2, but after the hardening mortar hardens, bolt 1 is removed together with the formwork shield 2. Thus, a cold bridge is excluded, since, firstly, the iron pin 5 does not come out on the surface of the walls (does not reach to the external and internal formwork panels), and secondly, it is closed with a plastic dowel 3, which, by definition, is a good heat insulator. This design prevents condensation from forming. In this case, the inner 2 and outer 10 formwork panels on the upper side through a threaded lug are connected to each other by an adjusting pin with threads applied to it from opposite sides in different directions (Fig. 2). By twisting this adjusting pin, you can adjust the required thickness of the formwork block and thereby adjust and level the thickness of the wall. In this case, optionally, the shuttering board 10 has a groove connection (Fig. 3) for fastening with adjacent shuttering boards 10 by a groove connection along the entire perimeter of the board 10. In this case, as an option, the shuttering boards 10 will be connected to each other with a latch lock (Fig. 4) along the entire perimeter of the shield, from the street side, and will also have corner stops from the street side, to create a downforce against the hardening solution 8 (not shown in the drawing). The use of the specified groove connection, latches-latches, the inner textured outer side of the shuttering board 10, the possibility of using an additional facing liner to the inner side of the outer shuttering board 10, ensure the creation of an exact width and even wall, any finishing texture, without visible seams and holes.

At the same time, since the pin 5 does not go through the formwork block and does not go out to the outer side of the hardening mortar 8, but ends in its thickness, not reaching the formwork panels, it is additionally ensured that a finishing texture of any depth, shapes, images and sizes is created on the outer wall without visible seams and holes.

After the installation and alignment of the formwork block, the hardening mortar 4, 8 is poured into the formed cavities, i.e. a double monolithic pouring into the specified formwork is formed.

In order for the external texture of the hardening solution 8 to turn out strictly in shape, it is necessary to expel all the air from it; for this, a construction vibrator is used, but since the thickness of the layer of the hardening mortar 8 will most likely not exceed 5 cm (more is possible, but impractical) on the formwork panels 10, from the street side there will be round grooves (not shown in the figures) for attaching the construction vibrator. Thus, the vibration of the shield 10 will be carried out and the air formed during the filling will escape. In addition to the inner side of the formwork 10 (on the side of the hardening mortar 8), different facing inserts can be installed, for example, cladding or basement panels, clinker tiles, siding, facade panels, for example, vinyl, plastic inserts for creating texture on the hardening mortar 8 and other facing elements.

The length of the studs that do not reach the edges of the outer and inner walls, as well as the presence of plastic dowels in the proposed formwork block on the studs, in which temporary bolts are installed (after the mortar has dried, the bolt is removed), ensures the elimination of condensation on the wall.
