Problems solved by technology

[0004] For example, the prefabricated steel bar connection structure of the famous Finnish Peikko company pre-embeds an angle steel with an end face, and then fixes one side of the steel bar on the angle steel by welding, and at the same time opens a hole on the end face, and then passes the other side of the steel bar through it. The end face is connected with bolts; although this method also realizes the connection with deviation of the butt joints, the angle steel used takes up a lot of space, the force is not direct enough, and when the number of butt steel bars is large, the installation and installation of the angle steel and bolts are difficult. Tightening is relatively complicated, so it is difficult to promote in a large area, and it is only used in the connection of small square columns in industrial plants.

Abstract

The invention provides an elastic sleeve rod piece connector, which comprises an elastic inner sleeve, an outer sleeve, an outer sleeve end anchor plate, a first flexible tension piece, a pressure bearing nut and a second flexible tension piece. The outer sleeve end anchor plate is arranged at one end of the outer sleeve and connected with one end of the outer sleeve through a thread pair; the outer sleeve end anchor plate is connected with a second rod piece, the elastic inner sleeve is anchored with the outer sleeve, and the elastic inner sleeve is connected with a first rod piece through athread pair; and the first flexible tension piece is arranged on the outer side of the outer sleeve, the end of the first rod piece is provided with the pressure bearing nut, and the second flexible tension piece is arranged on the outer side of the pressure bearing nut. According to the elastic sleeve rod piece connector, the size is small, adopted materials are saved, the construction speed is high, inspection is convenient, and the acceptance standard is definite.

Description

technical field [0001] The invention relates to the technical field of connection of structures, in particular to an elastic sleeve rod connector. Background technique [0002] In engineering construction, it is unavoidable that ordinary steel bars, prestressed steel bars, and other rods fixed on two assembly members have deviations within the allowable range when they are connected. , corrugated pipe reserved hole grouting connection and the use of connection boxes, etc. These connection methods have disadvantages such as complicated construction technology, undetectable quality, difficult to guarantee quality, and long waiting time to reach strength. If direct connection methods such as straight threaded connections are used , the positioning and manufacturing accuracy of the connecting rods are extremely demanding, and the error of half the pitch in the axial direction is an insurmountable obstacle. [0003] The bolt connection must be tightened to realize the complete c...
