Embodiment Construction

[0018] This embodiment is a method for strengthening the wall formwork behind the adjacent wall of the nuclear island factory building. The following steps are used to strengthen the wall formwork. The wall formwork is mainly composed of wood I-beams 8 and glued panels 9, and has upper and lower I-beams. Middle and lower main keels 12, 15, 16:

[0019] Step 1. Construct the steel frame - see figure 1 , after the construction of the first adjacent wall 1 is completed and the caulking material 4 is installed, the internal steel frame of the subsequent wall 2 is bound. The internal reinforcement frame consists of two groups of vertical structural reinforcements 7 respectively located on both sides of the follow-up wall, two groups of horizontal structural reinforcements 5 arranged up and down that intersect with the outer sides of the two groups of vertical structural reinforcements, and two sets of hooks and pulls respectively. The outside of the set of vertical structural stee...

Abstract

The invention relates to a method for reinforcing a rear wall body formwork of adjacent walls of a plant, which belongs to the technical field of building construction. The method includes steps of constructing a reinforcement structure; mounting formwork pulling connector; supporting the outer portion of a formwork; and the like. After the method is adopted, the wall body formwork forms an integral stressed structure with sufficient strength, rigidity and stability, mold expansion can be effectively avoided, and follow-up wall body construction quality and schedule are ensured.

Description

technical field [0001] The invention relates to a method for reinforcing a wall formwork, in particular to a method for reinforcing a wall formwork behind an adjacent wall in a nuclear island powerhouse, and belongs to the technical field of building construction. Background technique [0002] According to the applicant's understanding, the nuclear island plant is often divided into several plant areas according to the design function, and the direct structural connection between each plant area is not allowed, and settlement joints or expansion joints need to be set. During building construction, when the construction of the first adjacent wall is completed and the next adjacent wall needs to be built, the problem of supporting the wall formwork behind the adjacent wall must be encountered. Because the formwork here is difficult to establish a reliable force-bearing support point, it is prone to formwork expansion during wall pouring, so that the construction progress and q...
