The invention provides an improved prefabricated residential threaded connection sleeve device, comprising an outer sleeve; the top end of the inner cavity of the outer sleeve is connected with a steel bar connecting head through threads, and a rotatable wrench sleeve is arranged in the middle of the inner cavity. The bottom end of the inner cavity is connected with a support sleeve by a thread; a blind hole is provided in the top center of the steel bar connection head, and the inner wall of the blind hole is provided with an inner thread which is adapted to the steel wire head of the upper steel bar; the inner cavity of the wrench sleeve is movably arranged There is a corresponding reinforcing bar connecting nut, and the inner thread of the reinforcing bar connecting nut is matched with the reinforcing bar wire head of the lower reinforcing bar; the top end of the wrench sleeve is provided with a circle of teeth along its circumferential direction, and the cylinder wall of the outer sleeve is provided with a circle of teeth. And corresponding to the position of the teeth of the ring, a side hole is opened, a sleeve is fixedly arranged in the side hole, a driving rod is rotatably arranged in the sleeve, and the driving part of the driving rod is meshed with the teeth on the wrench sleeve. . The invention well realizes the mechanical connection of the prefabricated house.
Description
technical field [0001] The invention belongs to the technical field of sleeve connection for construction, and in particular relates to an improved assembled housing threaded connection sleeve device. Background technique [0002] At present, prefabricated houses are constructed using prefabricated parts. The upper and lower steel bars of the prefabricated part are mainly connected by grouting sleeves. There are many installation procedures for the grouting sleeve, the grouting should not be controlled, the installation efficiency is low, and it is easily affected by the level and responsibility of the grouting workers. At the same time, the quality of the grouting material and external conditions such as weather will affect the quality of the sleeve connection. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an improved threaded connection sleeve device for prefabricated houses in view of the deficiencies of th...
