Abstract

The invention discloses a positioning technology of a prefabricated shear wall bottom reinforcement sleeve in component production, which comprises the following steps: S1, manually mounting a grouting reinforcement sleeve on a reinforcement cage in a prefabricated shear wall in advance, and arranging sleeve end part internal threads at the end part of the inner wall of the bottom of the grouting reinforcement sleeve; and S2, the limiting steel sleeve is welded to the reserved circular hole of the bottom die through the welding technology, and it needs to be guaranteed that the whole limiting steel sleeve is perpendicular to the surface of the bottom die during welding. The inner screw threads are arranged on the inner wall of the steel bar sleeve at the bottom of the prefabricated shear wall, the limiting steel sleeve with the inner screw threads is arranged on the bottom die, then the bottom sleeve of the prefabricated shear wall and the bottom die are temporarily and fixedly connected together through the matched screw rod, the overall action effect is formed, and the steel bar sleeve is accurately positioned; the method is simple in technology, batch production can be achieved, and the problem of accurate positioning of the bottom sleeve during production of the prefabricated shear wall can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a positioning technology of a steel bar sleeve at the bottom of a prefabricated shear wall in component production. Background technique [0002] In the production stage of prefabricated shear wall, the positioning of the grouting steel sleeve at the bottom of the prefabricated shear wall on the bottom mold is a key link in product quality control. At present, in the domestic production process, the positioning of the grouting steel sleeve on the bottom mold is mostly fixed by rubber plugs. The rubber plug is deformed after being used for a long time, and it is not easy to fix the grouting steel sleeve firmly, which will lead to the deviation of the sleeve and the hidden danger of grout leakage. The above situation is unfavorable for the precise positioning of the grouting steel sleeve at the bottom of the prefabricated shear wall, and there are certain quality ris...
