Point claw type connecting piece for composite thermal insulation wall body, and construction and installation method of point claw type connecting piece

Abstract

The invention discloses a point claw type connecting piece for a composite thermal insulation wall body, and a construction and installation method of the point claw type connecting piece. The point claw type connecting piece comprises a claw disc, a center rod, bolts and chucks, wherein the lower end of the center rod is connected with the claw disc in a detachable way; connecting arms are distributed around the claw plate in an extending way; an end disc is arranged at the end of each connecting arm, and the bolts are respectively arranged on the end discs in a penetrating way; the at leasttwo chucks sleeve a threaded rod of each bolt by means of threads. The point claw type connecting piece can be effectively fixed with reinforcing steel bars, is suitable for multiple reinforcing steelbar distribution situations, and is high in shearing strength, small in heat transfer coefficient, corrosion-resistant, convenient for construction and good in fixing effect. The point claw type connecting piece solves the problems that more connecting pieces are used in the past, the single connecting piece is poor in performance, hot and cold bridges are serious, installation is complicated, fixation is not firm, and the connecting piece easily inclines and offsets in vibrating and pouring processes of concrete; the connection performance of inner and outer concrete slabs of a precast concrete composite insulation wall body is enhanced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a point-claw connector for composite thermal insulation walls and a construction and installation method thereof, which is mainly used for connecting the inner and outer leaf walls of prefabricated concrete composite thermal insulation walls. Background technique [0002] Energy conservation is a basic national policy of our country. Prefabricated buildings emerged as the times require. With the rapid development and promotion of prefabricated buildings, the improvement of building energy conservation has been paid more and more attention. Wall insulation is the most important part of prefabricated building energy conservation. Prefabricated concrete composite thermal insulation wall is a new type of prefabricated thermal insulation wall that integrates load bearing and thermal insulation. The wall is composed of inner and outer leaf concrete wall panels, intermediate i...
