Problems solved by technology

[0004] Because stone is a brittle material, the fireproof panel is prone to deformation, cracking and other conditions under high temperature, which will cause the plate to fall off, and the flame will go up to the upper wall along the broken position and enter the room. The smoke will escape to the upper floor, causing suffocation of personnel. However, the stone curtain wall in the prior art is fixed on the left joist and the right joist by pendants. The fire performance is poor and needs to be improved.

Embodiment

[0044] refer to figure 1 , a dry-hanging stone curtain wall construction method, the specific method is as follows:

[0045] (1) Install the embedded parts in each cast-in-place concrete floor slab according to the design drawings;

[0046] (2) During construction, the mortar on the surface of the steel plate of the embedded parts should be cleaned, and then the embedded parts should be re-checked according to the design drawings;

[0047] (3) Adjust the offset embedded parts;

[0048] 1) When the deviation of embedded parts is 45mm to 150mm, steel plates can be welded and installed on the original embedded parts;

[0049] 2) When the deviation of embedded parts is greater than 150mm, add welding steel plates to the original embedded parts, and then add steel plates to drill holes on the side away from the embedded parts, and fix them with 2 M12 chemical plugs. When installing steel plates, spot welding and positioning Then perform full welding;

[0050] 3) The deviation of ...

Abstract

The invention discloses a construction method of a dry hanging stone curtain wall, relates to the technical field of building construction, and aims to solve the technical problem that, in the prior art, flame and smoke dust easily spread into adjacent floors after a curtain wall is on fire. The key points of the technical scheme are as follows: (1) mounting an embedded part; (2) carrying out paying-off rechecking on the embedded part; (3) adjusting the deviated embedded part; (4) mounting a transverse keel and a vertical keel; (5) mounting a sheet hanging piece; (6) welding reinforcing steelbars and a main body lightning protection connection system; (7) mounting fireproof parts at floor slabs between adjacent floors; and (8) mounting a curtain wall. The construction method has the advantage of delaying the spreading of the fire of the floors to the adjacent floors.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a dry-hanging stone curtain wall. Background technique [0002] The curtain wall is the outer wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called a hanging wall. It is a light-weight wall with decorative effects commonly used in modern large-scale and high-rise buildings. China's stone curtain wall is a big country in the world's production and use. According to incomplete statistics, the annual average domestic stone decorative panels are about 25 million square meters for wall decoration, and about 140 million sets of stone curtain wall pendants are used; in terms of installation methods , usually divided into dry-hanging and wet-pasting, and stone curtain walls generally adopt dry-hanging installation methods, because dry-hanging is slightly more expensive than wet-pasting, but it has ...
