Abstract

The invention discloses a construction method of a door and window opening. The construction method comprises the following steps that a cross beam support mold and a wall support mold are manufactured; the cross beam support is erected; opening are formed in the two sides of the bottom of the cross beam support mold; the wall support mold is erected before a partition wall is poured, wherein thewall support mold internally comprises a to-be-poured partition wall area and a frame holding column area; second openings are formed in the portions, below the openings in the bottom of the cross beam support mold, on the two sides of the top of the frame holding column area; the wall support mold is erected at the bottom of the cross beam support mold, and foaming glue is injected at the jointsbetween the second openings of the frame holding column area and the openings in the bottom of the beam support mold; concrete is poured in the cross beam support mold, and the cross beam area, the partition wall area and the frame holding column area are integrally formed. By means of integral pouring, the engineering quantity in the independent construction stage is saved, the operation difficulty is lowered, the construction speed is increased, and the construction cost is reduced; the connecting structure of cross beams and frame holding columns is safer and more reliable due to the integrally formed arrangement.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for door and window openings. Background technique [0002] During building construction, it is usually necessary to design and construct door and window openings inside the building. When the door and window openings are set on the wall and the wall openings are larger than 300mm, in order to support various loads from the upper masonry of the door and window openings, and transfer these loads to the walls on both sides of the door and window openings, the door and window openings are often installed. beam. When the wall is turned or a door and window opening is opened on a thin T-shaped wall, in order to facilitate the placement of the door and window frame and ensure the stability of the wall, a frame column must be added to the partition wall on the side of the door and window opening. [0003] In the cast-in-place wall concrete project, ...
