Steel bar connection structure of prefabricated parts

Abstract

The invention discloses a steel bar connection structure of prefabricated parts. The steel bar connection structure of the prefabricated parts comprises a first prefabricated concrete member and a second prefabricated concrete member, and a connection box is embedded at the end, adjacent to the second prefabricated concrete member, on the first prefabricated concrete member; the connection box is provided with an opening side, and an opening of the opening side of the connection box is communicated with the surface of one side of the first prefabricated concrete member; the tail end of a first connecting steel bar in the first prefabricated concrete member is fixedly connected to a first side of the connection box, the tail end of a second connecting steel bar in the second prefabricated concrete member penetrates through a lower steel bar inserting hole in the lower bottom of the connection box, and the end of the upper end of the second connecting steel bar is connected and fixed to a nut and a pad sheet through a threaded screw thread. By the adoption of the steel bar connection structure of prefabricated parts, steel bar connection among prefabricated concrete parts becomes very easy, the steel bar butt joint is big in allowable variation, the construction difficulty is low, the steel bar connection is convenient, fast in speed and efficient, the technical problem in the construction industry that steel bar butt joint is difficult for many years is solved, the structure itself is mechanically connected, no aging exists, the structural strength is high, the service life is long, and the construction quality is good.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a steel bar connection structure of prefabricated components. Background technique [0002] In the existing building structure system, most of the connections between building components use sleeves as steel bar connectors, such as mechanical sleeves and grouting sleeves; this kind of sleeve connection makes it difficult for the steel bars protruding from the end of the building components to connect with the sleeves. cylinder alignment, the construction is difficult and the efficiency is low. For example, the grouting sleeve requires high preparation of grout, and the grouting is difficult to put in place, and the grout is prone to aging and crushing after a long time, resulting in loosening of the steel bars, reducing the structural strength and affecting the quality of the building; another example is the mechanical sleeve, where the steel bars pro...
