Installation method for assembly type building

Abstract

The invention discloses an installation method for an assembly type building. The installation method comprises the steps that 1, embedded parts, foundation bolts and connecting ribs are installed according to the drawing position height, and concrete is poured after reinforcement; 2, first-floor vertical component prefabricated wallboards and prefabricated columns are installed; 3, first-floor horizontal components are installed; 4, upper-layer prefabricated wallboards and prefabricated constructional columns are installed; and 5, the concrete is poured, and sequential cycle operation is conducted till the top of the structure is sealed. The installation method for the assembly type building has the beneficial effects that construction is rapid, safe and reliable, the quality is ensued, the efficiency is high, the construction period is greatly shortened, materials and artificial electricity cost are reduced through factory prefabrication, precise installing can be conducted, potential safety hazards are reduced, the pollution of sewage, waste, garbage, dust, noise, transportation which are produced by building site construction to the air environment is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a method for installing a prefabricated building. Background technique [0002] At present, the existing prefabricated buildings have the problems of poor structural integrity, heavy weight, low earthquake resistance, and high cost. The specific problems are as follows: [0003] (1) The wall panel is connected by steel sleeve grouting or bolted connection and welding (the embedded steel plate of the wall panel is welded and connected with the embedded structural parts), which has low connection strength and poor overall connectivity (the horizontal seam at the bottom of the wall panel cannot be connected) )The problem; [0004] (2) The floor slab is assembled by double pouring of laminated slabs, resulting in increased thickness and weight; [0005] (3) Wall panels are not installed with positioning devices, resulting in slow installation and construction efficiency; [0006...

AI Technical Summary

Problems solved by technology

[0002] At present, the existing prefabricated buildings have problems of poor structural integrity, heavy self-weight, low earthquake resistance, and high cost. The specific problems are as follows:

[0003] (1) The wall panel is connected by steel sleeve grouting or bolted connection and welding (the embedded steel plate of the wall panel is welded and connected with the embedded structural parts), which has low connection strength and poor overall connectivity (the horizontal seam at the bottom of the wall panel cannot be connected) )The problem;

[0004] (2) The floor slab is assembled by double pouring of laminated slabs, resulting in increased thickness and weight;

[0005] (3) Wall panels are not installed with positioning devices, resulting in slow installation and construction efficiency;

[0006] (4) Sleeve connection, secondary pouring of laminated slabs and concrete for the outer protective layer of wall panels not only increase the self-weight of the building itself but also increase the cost, and also reduce the earthquake resistance level, so it is necessary to improve the installation method of the existing prefabricated building

[0011] The above connection methods have the following disadvantages: ① few connection points and low connection strength; ② the connection joints of the upper and lower wall panels cannot be effectively combined, and the structural integrity and seismic performance are poor; ③ easy to seep water; The tube is difficult and the efficiency is low);

This process can save cast-in-place slab templates, but this connection method has the following problems: ①The cost of materials increases (the thickness of the laminated slab is generally greater than the thickness of the cast-in-place slab by ≥ 20%); ②The labor cost increases; ③The hoisting and transportation costs increase; ④ Hidden dangers in quality, cracking, hollowing, and poor bonding integrity caused by secondary pouring
