Abstract

The invention relates to a self-tightening half grouting sleeve connecting piece mainly applied to connecting of vertical reinforcing steel bars, including connecting of shear walls, frame columns and hanging board lamps. The self-tightening half grouting sleeve connecting piece is composed of a grouting opening (1), a thick liquid discharging opening (2), poking pieces (3), threads (4), a sleeve (5) and reinforcing steel bars (6). The diameter of the sleeve (5) is larger than the diameter of each reinforcing steel bar (6). The threads (4) are arranged on the inner wall of the sleeve (5). The grouting opening (1) is formed in the lower portion of the sleeve (5), the thick liquid discharging opening (2) is formed in the upper portion of the sleeve (5), and the poking pieces (3) are arranged in the position, between the grouting opening (1) and the thick liquid discharging opening (2), of the inner wall of the sleeve (5). The self-tightening half grouting sleeve connecting piece has the effects and advantages that the self gravity of the structure is utilized to conduct structure connecting, so that the structure is firmer; the diameter is increased slightly, so that the error-tolerant rate is increased; and meanwhile, connecting force is increased due to existing of the poking pieces, so that the length of the connecting piece can be reduced properly.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, in particular to a self-tightening semi-grouting sleeve connector. Background technique [0002] In the past few decades, my country's construction industry has flourished, which has greatly promoted the growth of the national economy. Faced with the increase of land transfer fees in our country, the continuous rise of labor prices, and the gradual improvement of people's awareness of energy conservation and environmental protection requirements, the construction industry is facing increasing pressure from international competition. In order to improve the core competitiveness, a new industry model - prefabricated buildings came into being. [0003] Prefabricated concrete structures refer to concrete structures assembled by prefabricated concrete components through reliable connection methods, including assembled integral concrete structures, fully assembled concrete structures, ...
