Abstract

FIELD: building, particularly for multilayer wall erection.

SUBSTANCE: method involves erecting building frame; installing outer and inner walls, wherein outer wall is formed of curtain facade wall panels; inserting heat-insulation means in air space between the walls. At first outer facade panels are hung over the full building facade with the use of lugs connected to vertical frame supports and mounting hooks fastened to the panels. Then as inner wall is erected space between inner and outer walls is filled with heat insulation.

EFFECT: possibility to isolate building interior from direct climate action and to perform finishing works in the building, namely masonry works, heat-insulation forming at any season, reduced speed and increased reliability of building assemblage, improved ability to compensate thermal deformations caused by varying outdoor temperature.

Description

The invention relates to the construction, namely, the technology of construction of a multilayer wall of buildings.

In connection with the increasing requirements for energy saving, the problem of heat conservation by buildings can be solved only with the use of multilayer walling with effective insulation.

Known three-layer reinforced concrete panel, including the outer and inner concrete layers with insulation placed between them [1].

The main disadvantage of the known panel, from which multi-layer walls of buildings are erected, is that with significant fluctuations in the temperature of the outside air, typical for regions with sharply continental climate, significant deformation of the outer layer and the creation of emergency situations are possible.

There is a method of erecting the outer wall of a multi-story building, including installing the outer and inner walls separated by an air gap, connecting them together and placing insulation between them, and the outer wall within each floor is installed on a reinforced concrete frame rigidly fixed to the supporting structures of the building after fixing a given butt gap with the following outer wall, and the floor-mounted installation of the outer wall, mainly of concrete panels, is performed prior to installation inside her prototype -. [2]

The main disadvantages of this method of construction of the outer wall are:

1. The complexity and complexity of installation associated with a large number of technological operations.

2. The ability to install the outer wall without first installing the inner wall only within the same floor.

3. The appearance of significant temperature stresses in the elements of the reinforced concrete frame.

4. Additional heat loss through the reinforced concrete frame and through metal bonds.

5. Limit the scope of multilayer walling in load-bearing and self-supporting walls and the inability to use in non-bearing (curtain) walls.

A known method of erecting an inner wall of small piece materials (eg, blocks or bricks) [3]. The technical task of the new method of erecting a multi-layer wall of a building is to reduce the complexity of the work, eliminate the causes of temperature stresses in the structures of the outer wall, create favorable conditions for construction in the winter.

The proposed method of erecting a multi-layer wall of a building differs from [2] in that the external hinged (non-supporting) wall in the form of a reinforced concrete rectangular panel is hung over the entire facade of the building using mounting hooks on the eyes installed on the supporting structures of the building, then the inner wall is constructed of lightweight masonry using small-sized materials (blocks or bricks) and as masonry is completed, the space between the inner and outer walls of the insulation is filled.

Introduced in the claims, such an essential feature, as the fact that, first of all, on the entire facade, the entire height of the building, including the multi-story building, hang external hinged (non-bearing) panels on reinforced concrete or metal structures of the building frame, allows after filling the window and exterior door openings to isolate the interior of the building from the direct impact of climatic factors, to conduct internal work on the laying of internal walls, laying or pouring thermal insulation at any time of the year.

An essential sign that the outer panels are hung only with the help of the existing hooks on the eyes mounted on the vertical supports of the frame provides a quick and reliable installation of facade panels.

An essential sign that the outer panels are freely hung on steel eyes allows you to compensate for thermal deformations of structures with fluctuations in the temperature of the outside air and to eliminate damage to the joints.

The method of erecting a multilayer wall is illustrated by drawings, where Fig. 1 shows a general view of a building under construction, and Fig. 2 is a fragment of a multilayer wall of a building during installation.

Symbols adopted in the drawings: 1, 2 - building frame; 2 - vertical supports; 3 - front panels; 4 - eyes; 5 - mounting hooks; 6 - masonry of small-piece materials (blocks or bricks); 7 - insulation.

The method is as follows: after the construction of the building frame 1, 2 of reinforced concrete or metal structures on the vertical supports 2 of the frame, rectangular façade panels 3 are hung using eyes 4 located on the vertical supports 2 and mounting hooks with a downward bend 5. During installation use hoisting construction equipment: various types of cranes, etc. Then, masonry is made from small pieces of materials (blocks or bricks) from the inside of the building 6. The space formed between the facade panels 3 and masonry 6 is filled with insulation 7. The length of the mounting hooks is taken depending on the thickness of the insulation, which is established according to the results of the heat engineering calculation. Facade panels can be either solid or with window or door openings. The height of the panels 3 is taken, as a rule, equal to the height of the floor, and the width equal to the distance between the vertical supports of the frame 2.

The advantages of the method are:

- elimination of the possibility of additional stresses with changes in the temperature of the outside air;

- providing conditions for the construction of the building at any time of the year:

- the ability to install external panels throughout the facade of a multi-storey building before installing the inner wall and thermal insulation without the use of additional scaffolding and scaffolding;

- installation or pouring of insulation into the space between the inner and outer walls from the side of the room without installation from the outer side of scaffolding and scaffolding;

- use of the hinged front panel only as a building envelope for insulation.
