It helps improve the heat-insulation, increase its lifetime, and reduce the consumption of materials and labour. The wall consists of a hollow construction body (1) with profiled inside surface (2), which is made of concrete cast on the spot. The body (1) comprises a front partition (3) and an intermediate partition (4) forming a front cavity (6), as well as a transverse partition (7), an inner partition (8) and a lateral partition (9) forming respectively an inner left cavity (11) and an inner right cavity (12). In the front cavity (6), along the whole volume thereof, there is built-in a heat-insulation pack (13), while in the inner left cavity (11) and in the inner right cavity (12) there is built-in heat-insulation material (16) of mineral wool.

Description

Regional technology

The utility model relates to a wall for the construction of buildings, in particular an exterior wall for the construction of residential, office and industrial buildings.

BACKGROUND OF THE INVENTION

An external wall is known for constructing buildings that are made of bricks or aerated concrete blocks or panels, as well as cast concrete in place and others, with a layer of plaster (exterior plaster) on the outer surface of the wall. A fixed thermal insulation package is attached to the outer wall, which consists of foam boards, which are located on the outer surface of the wall from which the building is constructed. On the outer surface of the foam boards there is an intermediate layer, in which is embedded a fabric of glass fibers, formed in the form of a mesh, and in the slit spaces between the fibers there is a plaster. The intermediate layer is made of polyvinyl chloride, which contains quartz flour as a filler material. An outer layer of plaster (outer plaster) is formed on the outer surface of the intermediate layer, which consists of a mineral aggregate dispersed in a binder [1].

The technical nature of the utility model

The composite wall for the construction of buildings includes a construction body connected to a fixed thermal insulation package, the construction body being constructed of cast concrete in place.

According to a useful model, the construction body is shaped as a hollow with a profile inner surface and contains a front and intermediate barrier / part /, between whose inner surfaces is formed a front cavity / air chamber /, and between the transverse, internal and lateral barriers, as well as the intermediate barrier , the inner left and inner right cavities are formed respectively. The entire cavity has a thermal insulation package in its entire cavity, in which the contact surfaces with the hollow building body are formed respectively by recesses and projections facing each other both vertically and horizontally, which are shaped like a swallow tail, through which a fixed connection is made between the building block and the thermal insulation package. Thermal insulation material is incorporated in the inner left and inner right cavities.

The technical nature is further clarified by another embodiment, in which the swallow tails formed in the contact surface between the building body and the thermal insulation package are at least one in a vertical and horizontal direction.

In another embodiment, the thermal insulation package and the thermal insulation material are made of polystyrene or mineral wool.

In a further embodiment, the thermal insulation package comprises, in the range of the contours, a heat-reflecting layer made of organosilicon material.

The advantages of the utility model are that it improves the degree of thermal insulation and increases its life, since the thermal insulation package is built into the building body and the adhesion / connection / between them is made with a swallow tail, while at the same time the heat reflecting layer does not allow to go through the wall inside and out. In addition, the materials and labor involved in its construction are reduced due to the fact that the construction body and the thermal insulation package are built simultaneously with the construction of the building and due to the presence of the shaped voids, as well as the possibility to use a construction body of precisely defined dimensions.

Explanation of the annexed figures

Figure 1 is a longitudinal section (horizontal) of the composite wall for the construction of buildings.

Examples of implementation of the utility model

The composite wall for the construction of buildings consists of a construction body 1, shaped as a hollow with a profile inner surface 2, which is made of concrete or mortar (cast concrete in place). The construction body 1 comprises a front 3 and an intermediate partition 4, between whose inner surfaces 5 is a front cavity 6 (intermediate chamber). In addition, it also contains a transverse 7, an inner 8 and a lateral septum 9, whose inner surfaces and the outer surface 10 of the intermediate septum 4 form an inner left 11 and an inner right cavity / chamber / 12. In the front cavity 6, its entire volume is a built-in thermal insulation package 13, made of styrofoam, in which the contact surfaces 14 with the hollow building body 1 contain respectively recesses and projections facing each other, both horizontally and vertically, in the form of a swallow tail in a single number in the front 3 and 4. The inner left cavity 11 and the inner right cavity 12 are provided with thermal insulation material 16 made of mineral wool or the inner left 11 and the inner right cavity 12 are designed as airbags 17.

In a further embodiment, the construction body 1 is made of lightweight concrete with lightweight additive materials or foam concrete or other similar materials.

Using the utility model

The composite wall is constructed as follows: After reinforcement and concreting of the columns along the entire height of the wall, it is constructed pre-prepared blocks on site or in the production base by forming concrete, which is pre-placed in a shuttering form with integrated thermal insulation. package 13. The construction body 1, which is formed by a formwork form, is constructed of concrete or mortar or concrete with lightweight additive materials which are simultaneously molded with the respective insulation package 13 with the corresponding and concrete form with strictly defined dimensions.
