Construction method of floor post-cast strip

Abstract

The invention belongs to the field of building construction, and particularly discloses a construction method of a floor post-cast strip. According to the construction method, secondary concrete chiseling is not needed, and pre-cast concrete slurry can be prevented from permeating into a post-cast strip space. According to the construction method, side formworks mainly made of dense-mesh steel wire meshes serve as supports on the two sides of the post-cast strip space, and before concrete of structures on the two sides of the post-cast strip space is poured, the post-cast strip space is filled with temporary filler, so that the pre-cast concrete slurry can be prevented from permeating into the post-cast strip space, the pollution cleaning work of the slurry to the formworks is reduced, and the side formworks do not need to be detached and supported separately; and in addition, the surfaces of the concrete mainly wrapped by the side formworks made of the dense-mesh steel wire meshes are uneven, secondary concrete chiseling is not needed, and the workload of constructors is reduced.

Description

Technical field[0001]The present invention belongs to the field of construction, and is disclosed in the construction method of a floor rear ladle.Background technique[0002]The floor rear lace is in building construction to prevent the current pouring reinforced concrete structure from generating harmful cracks due to its own shrinkage or settlement unevenness, according to the design or construction specifications, the rear pouring concrete belt in the bottom plate and the floor . The reservoir reservoir is generally not less than 800mm, and the rear reinforcing bar is generally constantly being opened; the concrete on both sides of the lathed tape is poured first. After curling, 42 days of maintenance can be poured.[0003]When construction, the template is required to separate the lassis space, pour the structure on both sides of the rear tape. After the structural strength of the two side is in line with the norm, the side mold of the rear poured tape space is required, and the la...

AI Technical Summary

Problems solved by technology

The problems of this method are: the bottom of the formwork or the joints at the joints are not tight enough to cause local small-scale grout leakage. After the structural concrete is poured, it is difficult to take out the wooden formwork in the steel mesh, and the formed structural concrete needs to be chiseled twice. , causing a lot of construction clean-up and workload
