Bidirectional deviation rod piece connector of elastic combined nut

Abstract

The invention discloses a bidirectional deviation rod piece connector of an elastic combined nut. The connector comprises a first elastic combined nut, a first anchoring sleeve, a middle connecting sleeve, a second elastic combined nut, a second anchoring sleeve, a first pressure-bearing nut assembly and a second pressure-bearing nut assembly, the first elastic combined nut and the second elasticcombined nut comprise a plurality of threaded clamping pieces on elastic reset pieces, the first anchoring sleeve and the second anchoring sleeve comprise anchor cups, middle anchor plates, end anchorplates and spherical gaskets, and the first pressure-bearing nut assembly and the second pressure-bearing nut assembly comprise pressure-bearing nuts and leading-out tightening assemblies; the firstanchoring sleeve and the second anchoring sleeve have multidirectional constraint and anchoring effects on the first elastic combined nut and the second elastic combined nut; the middle connecting sleeve is connected with and anchors the first anchoring sleeve and the second anchoring sleeve; and the pressure-bearing nuts compress the anchoring sleeves to provide the compression resistance of a rod piece. The connector is small in size, material-saving, high in construction speed, convenient to detect and inspect and clear in acceptance standard.

Description

technical field [0001] The invention relates to the technical field of connection of structures, in particular to an elastic combined nut anchoring deflection rod connector. Background technique [0002] In engineering construction, it is unavoidable that ordinary steel bars, prestressed steel bars and other rods fixed on two butt joints will deviate within the allowable range. In order to adapt to this butt joint deviation, grouting sleeve connections are mostly used at present , 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 i...

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.
