Elastic firing pin alignment assembling type rod piece connector

Abstract

The invention discloses an elastic firing pin alignment assembling type rod piece connector. The connector comprises a connecting shaft, a connecting shaft nut, a fixing pin, an elastomer, an inner sleeve, an outer sleeve, a first end anchor plate, a second end anchor plate, a spherical gasket, a second connecting sleeve, a third end anchor plate, a fourth end anchor plate and a first flexible tension member; the inner sleeve, the spherical gasket, the outer sleeve, the first end anchor plate and the second end anchor plate form a first anchoring sleeve; the second connecting sleeve, the thirdend anchor plate and the fourth end anchor plate form a second anchoring sleeve; the connecting shaft, the connecting shaft nut, the fixing pin and the elastomer form an elastic connecting firing pin, and the elastic firing pin is connected to the first anchoring sleeve and the second anchoring sleeve; the first anchoring sleeve is connected to a rod piece II; and the second anchoring sleeve is connected to a rod piece I. According to the connector, the alignment butt joint of the rod pieces in an assembly structure is realized, the detection and inspection are facilitated, and the acceptancestandard is clear and definite.

Description

technical field [0001] The invention relates to the technical field of connection of structures, in particular to an elastic striker snap-fit ​​bar 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 th...

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.
