Construction method of integrated external wall building system

Abstract

The invention relates to a construction method of an integrated external wall building system. The construction method comprises the following construction steps: 1) precast concrete plates are precast in a factory; 2) proper lifters are selected according to component forms and lifting heights; 3) the precast concrete plates are lifted to a construction position; 4) the precast concrete plates are stopped descending when from a mounting distance by 50 cm to check if the front and reverse surfaces of the concrete cast plates are consistent with a drawing; 5) the positions of the precast concrete plates are primarily fixed according to an anchor bolt embedding position; 6) the anchor bolt embedding position is precisely adjusted according to a control line to overlap with a surveying and setting-out position; 7) the precast concrete plates are in place, and are fixed on columns through fixed nuts; 8) reserved tensioned reinforcements of the precast concrete plates and block external walls are built together; and 9) through seams are formed between the other sides of the columns and the block external walls. The construction method has such advantages as convenient construction, capability of reducing the thickness of column wrapped wallboards and reduction of the beam and column projection risk.

Description

【Technical field】 [0001] The invention relates to a construction method of a building exterior wall, in particular to a construction method of an integrated exterior wall masonry system, and belongs to the technical field of construction engineering. 【Background technique】 [0002] The masonry wall refers to the wall made of bricks or blocks, which is one of the main components of the building and plays the role of enclosure and load bearing. Masonry walls have many advantages such as thermal insulation, heat insulation, and sound insulation. [0003] The steel-concrete partial composite column is a new type of composite member proposed in Europe in the 1980s. The basic type of its section is to fill concrete between the flanges of H-shaped steel members. This composite column has the advantages of large bearing capacity and high rigidity. [0004] When the masonry wall and the steel-concrete composite column are combined to form a new type of masonry exterior wall, there ...

AI Technical Summary

Problems solved by technology

Columns need to be covered with wall panels, which will occupy the building area, and at the same time, the risk of convex beams and convex columns is likely to occur indoors

[0006] 2. The construction is difficult, the precision is poor, the integrity is poor, and cracks are easy to occur

[0007] 3. The construction efficiency of masonry walls and external column masonry in the market is low
