Construction method of outer wall board provided with precast window frames for fabricated concrete structure building

Abstract

The invention discloses a construction method of an outer wall board provided with precast window frames for a fabricated concrete structure building. The construction method comprises the following steps that door windows are manufactured according to the size of a member drawing; door window openings and door window opening fixing moulds are precast; the moulds are assembled and fixed on a mouldtable, the interiors of the moulds are brushed with isolating agents, and the door window frames are mounted according to the drawing; seams between the window frames and seams between the window frames and the moulds are filled with foaming agents in a foaming mode; concrete is poured, and after curing, off-line mounting of door window sashes and hardware is conducted; and wood boxes for protecting finished products are removed, and construction is finished. Mounting is conducted in advance before structural top sealing or completing of most of the workload, thus the construction progress isaccelerated, and construction safety is improved.

Description

technical field [0001] The invention generally relates to the construction field, in particular to a construction method for an exterior wall panel provided with a prefabricated window frame for a prefabricated concrete structure building. Background technique [0002] The doors and windows installed on the external wall panels of the existing prefabricated concrete structure buildings adopt the openings of the doors and windows reserved on the prefabricated wall panels, and then the door and window frames are installed before the main structure is completed and the rough decoration is completed. Foam caulking and plastering on the inside and outside around the opening. [0003] The problems and shortcomings of the existing technology are that the door and window frame is installed after leaving a hole in the process, resulting in a gap between the frame and the structure. Although it has been plastered with a foaming agent, it is very easy to operate due to the manual opera...

AI Technical Summary

Problems solved by technology

[0003] The problems and shortcomings of the existing technology are that the door and window frames are installed after leaving holes in the process, resulting in gaps between the frame and the structure. Although it has been plastered with a foaming agent, it is very easy to install because it is manually operated by on-site workers. There are hidden dangers of leakage or quality problems, and installation will affect the construction progress of subsequent processes after the structure is capped or most of the work is completed

The current construction projects are more or less lagging behind the progress of door and window installation

And the installation at heights will greatly increase the risk of safety
