RU2095533C1 - Method for erection of external wall of building - Google Patents

Abstract

FIELD: construction engineering. SUBSTANCE: this relates to technology of erecting laminated external walls of dwelling and public buildings, including multistory buildings. According to method, external wall of building is made by erecting light-weight walling of small-piece materials isolated by air spacing from internal load-bearing walling. These two components of external wall are interconnected, and warmth-keeping interlayer is installed between them. Masonry within each separate story of building is separated from above-laying masonry by placing reinforced concrete frame of permanent thickness on temporary screeds in upper face of low-laying masonry. Frame is fixed in this position and then it is rigidly secured at opposite side to internal walling. Then wall is erected within next story with subsequent removal of screeds and hermetic sealing of clearance. EFFECT: high efficiency. 4 dwg

Description

 The invention relates to construction, and in particular to a technology for the construction of laminated exterior walls for residential and public buildings.

 The closest technical solution to the proposed one is the method of erecting the outer wall of the building by erecting lightweight masonry separated from the air gap from small pieces and mainly the internal supporting wall, connecting them together and possible installation of insulation between them (see ed. St. USSR N 685780, class E 04 B 2/42, 1979).

 A disadvantage of the known solution is the impossibility of using it for the walls of multi-storey buildings, since the bearing capacity of lightweight masonry from the influence of its own mass is limited to a height of about 2 3 floors.

 The purpose of the invention is the use for walls of a multi-story building.

 This goal is achieved by the fact that in the method of erecting the outer wall of the building by erecting lightweight masonry separated from the air gap from small pieces and mainly the internal bearing wall, connecting them together and installing insulation between them, the masonry within each floor of the building is separated by a gap from the overlying masonry due to the installation on its upper face on temporary beacons of a constant thickness of the reinforced concrete frame on the floor, fixing the frame in this position, then rigidly fastening it with false sides to the inner wall of the frame and the construction of masonry within the next floor, followed by removal of beacons and sealing the gap.

 As an example, consider the options of the proposed method with an internal load-bearing wall of brickwork and concrete panels.

 In FIG. 1 shows a vertical section of a wall with an internal wall of masonry during the construction process; in FIG. 2 the same at the end of the erection to the height of the floor; in FIG. 3 vertical section of the wall with the inner wall of concrete panels during the construction process; in FIG. 4 the same at the end of the erection to the height of the floor.

 On the basement of a multi-storey building, lightweight masonry 1 made of small pieces, for example, of face brick or face stone of 1/2 brick or stone, and the supporting inner wall 2 of brickwork or concrete panels are erected, separated by an air gap. The masonry 1 and the wall 2 are interconnected by bonds 3, for example, metal, and a heater 4 made of an effective material, for example, polystyrene or mineral wool boards, is installed in the space between them. On the upper edge of the lightweight masonry 5 erected to a height of 1 floor to form a gap 6, temporary beacons 7 are laid out on a floor of constant thickness from easily destructible material, for example, polymer or wood. On one side, a reinforced concrete frame 8 with slots 9 in the middle part is installed for passing insulation 4. After fixing the position of the frame on the beacons 7, for example, with the mass of masonry built on it in 1 2 bricks, its opposite side 10 is rigidly fixed to the inner wall 2, for example, monolithic in masonry (see Fig. 1) or welding (see Fig. 3). Then, on the frame 8, masonry 11 is erected to a height of 2 floors and all previous operations are repeated. At the same time, temporary beacons 7 are removed from the gap 6, for example, by heating to soften or by burning, and it is filled with sealant 12, for example, with mastic over a rubber cord or polyurethane foam. To ensure relative equality of the gap 6 on all floors of masonry 2, the thickness of the beacons 7 can be changed floor by floor, taking into account the uneven mutual settlement of lightweight masonry 1 and the inner wall 2.

 The implementation of the proposed method makes it possible to erect the outer walls of multi-storey residential and civil buildings of various structural systems with the required high thermal protection and high-quality facade made of face brick or stone.

Claims (1)

 A method of erecting an exterior wall of a building, including erecting a lightweight masonry separated from the air gap from small pieces and primarily an internal supporting wall, connecting them together and installing insulation between them, characterized in that after erecting the masonry of each floor, beacons of constant thickness are placed on the floor on the floor and reinforced concrete frame with slots in the middle part for the passage of insulation, fix the frame and fasten it to the inner wall, after which the masonry is erected on the frame as follows on the floor and remove the lighthouses, and the clearances formed by them is filled with sealant.
