Construction method for connecting wallboards by reversely inserting single-end cold rolling head grouting sleeve

Abstract

The invention discloses a construction method for connecting wallboards by reversely inserting a single-end cold rolling head grouting sleeve. The construction method changes a traditional wallboard connecting construction method. The method comprises the steps of firstly respectively cold rolling a single-end cold rolling head at the bottom end of a grouting sleeve on a stressed rib at the upperend part of a plane truss of a lower wallboard by adopting a hydraulic machine, respectively installing an upper wallboard in place, then grouting the grouting sleeve with ready-mixed slurry from theupper opening of the grouting sleeve into the sleeve, inserting the stressed connecting rib head exposed and extending out of the bottom of the upper wallboard into the grouting sleeve after the grouting is full, and correcting the fixed position of the upper wallboard until the bottom of the upper wallboard is placed at the upper opening of the grouting sleeve at the top of the lower wallboard. According to the method, the grouting sleeve is prefabricated in the lower wallboard and fixed on the stressed steel bar head at the top of the plane truss by cold rolling to ensure that the stressed steel bars at the upper layer and the lower layer are communicated and reliable through the stress connection of the grouting sleeve, and the connection requirement of an assembled building structure is met; the method is convenient to assemble and construct, and the quality is visual and reliable.

Description

technical field [0001] The invention belongs to the technical field of construction, and more specifically relates to a construction method for connecting wallboards by using a single-end cold rolling head grouting sleeve reverse insertion method. Background technique [0002] The inventor found through research that the current prefabricated buildings have no control over the grouting quality of the original grouting sleeve, and the connection is unreliable. Under the situation of being questioned by the industry, how to invent a grouting sleeve using a single-ended cold rolling head The construction method of plug-in connection wallboard improves these problems, has become a problem to be solved urgently by those skilled in the art. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a construction method using a single-end cold rolling head grouting sleeve reverse insertion method to connect ...
