Side wall open-hole anchoring bidirectional off-position rod piece connector

Abstract

The invention relates to a side wall open-hole anchoring bidirectional off-position rod piece connector. The side wall open-hole anchoring bidirectional off-position rod piece connector comprises first elastic combination nuts, a first anchoring sleeve, a middle connecting sleeve, second elastic combination nuts, a second anchoring sleeve, a first pressure-bearing nut assembly and a second pressure-bearing nut assembly; the first elastic combination nuts and the second elastic combination nuts include a plurality of pieces of threaded clamping pieces in elastic reset parts, and the first anchoring sleeve and the second anchoring sleeve include open-hole anchor cups; the first pressure-bearing nut assembly and the second pressure-bearing nut assembly include pressure-bearing nuts and guide-out screwing combination pieces, and a plurality of window holes are formed in the side walls of first open-hole anchor cups and second open-hole anchor cups; the first elastic combination nuts and the second elastic combination nuts are oppositely arranged in the window holes of the side walls, and the first anchoring sleeve is connected with the second anchoring sleeve through the middle connecting sleeve, and the first anchoring sleeve and the second anchoring sleeve are anchored by the middle connecting sleeve; and the pressure-bearing nuts tightly press the anchoring sleeve to provide thecompressive capacity of rod pieces. According to the side wall open-hole anchoring bidirectional off-position rod piece connector, the size is small, the material consumption is less, the construction speed is fast, the detection and the inspection are convenient, and the acceptance criteria is clear.

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 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 tightene...

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.
