Problems solved by technology

[0003] The common practice is prone to deviation or irregularity after demolition, and it is not easy to adjust
The reason is that it is difficult for workers to control the simultaneous feeding of both sides during concrete pouring, and it is impossible to ensure that the vibration is complete at the same time, so the lateral pressure on the door and window opening formwork is different. When the lateral pressure is greater than the supporting force of the steel bar, the formwork will be deformed or deflected. shift
If the amount of deformation is too large, it will affect the installation of doors and windows in the future

Abstract

The invention discloses a process method for reinforcing the door and window of large formwork construction. The process method for reinforcing the door and window of the large formwork construction comprises the following steps: the first step is to weld an angle steel which moves in a horizontal direction on a large formwork on one side of the wall mold; the second step is to weld an adjustablebolt on the angle steel, wherein the adjustable bolt comprises a handle, a screw, a nut and a bolt plug, wherein the nut is fixed on the angle steel, the screw rod is in threaded connection with the nut, the handle and the bolt plug are respectively fixed at the two ends of the screw, and the screw and the bolt plug are rotated with the handle; the third step is to manufacture the door and windowformwork which is reinforced by the supporting angle steel. The process method for reinforcing the door and window of the large formwork construction can weld the angle steel of the adjustable bolt onthe large steel mold on one side of the wall mold, and through adjusting the wall mold, minor adjustments can be made to correct the error of horizontal and vertical parameters caused by external factors.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a process method for reinforcing door and window openings in large formwork construction. Background technique [0002] In today's formwork engineering, large formwork has gradually become the main formwork engineering construction technology. In the process of large formwork construction, the reinforcement of door and window openings is a difficult problem. The commonly used method is: when supporting the door and window openings, set supports around the door and window openings according to the horizontal and vertical dimensions of the openings, set angle steel connections at the four corners and set diagonal braces to ensure the overall shape of the doors and windows; then set the positioning of the fixed door formwork Ribs (the ends are cut with a toothless saw and painted with anti-rust paint), and the positioning ribs are welded to the additional U-shaped irons, and mu...
