Moving drivepipe neat-joint assembling rod piece connecting device

Abstract

The invention discloses a moving drivepipe neat-joint assembling rod piece connecting device. The moving drivepipe neat-joint assembling rod piece connecting device comprises a connecting shaft, an inner drivepipe, an outer drivepipe, a first end anchor plate, a second end anchor plate, a spherical gasket, a second connecting drivepipe, a middle anchor plate, a first nut, an elastomer supporting piece, an elastomer and a fixing pin. The inner divepipe, the spherical gasket, the outer drivepipe, the first end anchor plate, themiddle anchor plate and the second end anchor plate form a first anchoring sleeve, the first nut, the elastomer supporting piece, the elastomer and the fixing pin form an elastic mechanism which pushes the first anchoring sleeve, the connecting shaft is connected withthe second connecting sleeve and the first anchoring sleeve, the second connecting drivepipe is connected with a first rod piece, and the first anchoring sleeve is connected with a second rod piece. According to the moving drivepipe neat-joint assembling rod piece connecting device, the butt-joint of the nest joint in the rod pieces of the assembling structure is achieved, inspection and examination are convenient, and the acceptance standard is clear.

Description

technical field [0001] The invention relates to the technical field of connection of structures, in particular to a connector for moving sleeves and splicing rods. 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 reali...

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.

[0005] In particular, all current prefabricated assembly structures have two male and female joints for connecting rods, and the rods of the male and female joints protrude from the prefabricated components, which brings great inconvenience to transportation and installation.
