Method of filling expansion joints of shear wall with foam boards for fixation

Abstract

The invention discloses a method of filling expansion joints of a shear wall with foam boards for fixation. The method is characterized by comprising the following steps that a, multiple foam board fixing devices are prefabricated; b, the positions of the foam boards and plastic extruding sheets are marked on pulling screw rods; c, steel ring pieces which are welded fixedly are prepared; d, the plastic extruding heat-preservation sheets which are 1,950 mm long and 500 mm high are spliced previously on the front and back sides of the foam boards on the wall which is 1,950 mm long and 1,000 mm high, and the plastic extruding sheets are bonded to the foam boards through double-faced adhesive tape; e, the foam boards which are spliced in advance are hoisted to a mounted floor; f, installationof the first foam board at the bottom is completed; g, the second and third foam boards are installed in sequence; h, a cement support for controlling the thickness of the wall is placed, and wall frameworks on both sides are installed in sequence. The method has the advantages that reinforcing devices are simple in structure and convenient to manufacture, and the problem that the foam boards andthe plastic extruding heat-preservation sheets seriously deviate during pouring is effectively solved and alleviated, and the engineering cost is reduced.

Description

Technical field [0001] The invention relates to a method for fixing a foam board in the construction field, in particular to a method for fixing a foam board filled between expansion joints of a shear wall. Background technique [0002] In the construction of the shear wall structure of high-rise residential buildings, due to the high floors, most of the expansion joints of the shear wall use pre-embedded foam boards and extruded insulation boards as wall templates. This kind of wall formwork system solves the disadvantages that it is difficult to take out the wooden square and formwork after pouring the expansion joints, saves turnover materials, and saves the process of filling insulation materials in the later stage. However, due to the low rigidity of the foam board, the fixing measures for the foam board and the extruded board during the on-site construction are not in place, which is likely to cause serious deviation of the actual shear wall, resulting in the deviation of t...

AI Technical Summary

Problems solved by technology

However, due to the low rigidity of the foam board, the fixing measures for the foam board and the extruded board are not in place during the on-site construction, which is likely to cause serious deviation of the actual shear wall, resulting in the offset of the structural wall axis and the reduction of the local section size of the wall Phenomenon, the quality of structural perception is not ideal, which affects the overall mechanical performance of the structure

[0003] Therefore, there are above-mentioned inconveniences and problems in the known fixing method of filling foam boards between expansion joints of shear walls.
