Keel components and construction methods used in in-situ foam concrete for filling walls in the building insulation reverse method

Abstract

The present invention relates to a keel assembly in the reverse construction method for building heat preservation and a construction method for pouring foam concrete on-site for filling walls in the inverse construction method for building heat preservation. The construction method includes three steps of processing thermal insulation prefabricated panels, installing thermal insulation prefabricated panels, and cast-in-place construction; the present invention adds supporting devices for keel assemblies and free internal templates, and utilizes the advantages of little shrinkage of foamed concrete during solidification and drying to make pouring The body remains tightly bonded and fully supported at all times; the use of the non-demolition formwork can effectively avoid the defects of premature demolition and easy cracking, and the pouring body is self-cured in the mold, saving water resources, and maintaining the density of the pouring body itself, balanced stress, The molecular structure is stable and does not affect the follow-up process, saving cost and time; the organic combination of building energy saving and building structure complements each other's advantages, reduces overall cost, improves overall quality, and reduces unnecessary waste.

Description

technical field [0001] The invention relates to a keel component and a construction method used in the poured-in-place foam concrete for filling walls in the building insulation reverse method, and belongs to the technical field of building construction methods. Background technique [0002] At present, the existing filling wall construction methods, except that the shear wall part already uses the outer thermal insulation prefabricated slab, and the concrete is cast in place at the same time as the beams and columns, other types of blocks (including self-insulation blocks) are basically used. and aerated block) masonry is completed, and the block masonry filling wall has the following defects: [0003] 1. Poor security [0004] 1. Pressed hollow brick series, because of its high density and heavy weight, the strength is weakened after being hollowed out, and the solidification strength and water resistance of the cement are weakened due to the low-moisture blank necessary ...

AI Technical Summary

Problems solved by technology

[0017] The purpose of the present invention is to solve the problems of poor safety of existing block masonry filling walls, cumbersome construction technology, long construction period, large block production equipment, long production cycle, and easy generation of construction waste, and to provide an overall safe The keel components and construction methods used in the in-situ foam concrete for filling walls are high, the process is simplified, the construction period is short, the production equipment is simple, there is no construction waste, and the production cycle is short.
