A construction method for anti-displacement construction of pre-embedded groove of finished support

Abstract

The invention relates to an anti-displacement construction method for a pre-embedded groove of a finished bracket, comprising: step 1, using an electric drill to install several anchor bolts on the pre-buried groove of the finished bracket to form the first pre-buried groove of the finished bracket; step 2, using a torque The wrench installs the bolts on the embedded groove of the first finished bracket to form the embedded groove of the second finished bracket; Step 3, fix the grouting template, and put the embedded groove of the second finished bracket into the target installation position, so that the second The axis height deviation and position deviation of the embedded groove of the second finished bracket meet the preset conditions, and at the same time, the surface of the embedded groove of the second finished bracket is closely attached to the grouting surface; and the distance between the steel bar is measured, so that the actual distance d meets the preset conditions, and welding is carried out; thereby the verticality of the second finished bracket embedded groove can be accurately controlled, and then the deviation of the finished bracket embedded groove of the present invention can be prevented. Move, improve the efficiency of on-site installation.

Description

technical field [0001] The invention relates to the technical field of infrastructure installation, in particular to a construction method for preventing displacement of a pre-embedded groove of a finished support. Background technique [0002] my country's building construction has achieved rapid development in recent years. Construction units have made a lot of innovations in underground construction methods and construction materials. The use of pre-embedded prefabricated finished product supports and hangers in construction construction is more efficient and in line with the concept of prefabricated engineering. At present, the existing prefabricated finished support and hanger mainly adopts the pre-buried groove of the finished support. During the construction of the pre-embedded groove of the finished support, during the concrete pouring and vibrating process, the pre-embedded support will be offset with the offset of the wall panel reinforcement. [0003] At present,...

AI Technical Summary

Problems solved by technology

[0003] At present, there are already some construction methods that can prevent the deviation of the embedded groove of the finished support, but the verticality and installation position of the embedded groove cannot be precisely controlled, the efficiency of on-site installation is low, and the flatness of the concrete pouring formed components is not high
