Abstract

The invention discloses an ellipsoid type reinforcing steel bar connecting piece. The ellipsoid type reinforcing steel bar connecting piece comprises a lock head and a lock body, the lock head comprises an upper sleeve, a bolt hole is formed in the upper portion of the upper sleeve, an empty groove is formed in the upper sleeve, the diameter of an upper ellipsoidal empty groove is slightly largerthan the diameter of a middle cylindrical empty groove, two semicircular steel discs are arranged on the periphery of the middle cylindrical empty groove, springs are arranged at the outer side ends of the semicircular steel discs, and circular steel discs are connected with the upper sleeve through the springs. The lock body comprises a lower sleeve and a cylinder body, a bolt hole is formed in the lower sleeve, and the cylinder body is composed of an upper ellipsoidal cylinder body, a middle cylindrical cylinder body and a lower cylinder body. The diameter of the upper ellipsoidal cylinder body is slightly larger than the diameter of the middle cylindrical cylinder body, and the cylinder body is matched with the shape of the empty groove. The construction is easy to operate, the connection between reinforcing steel bars is realized by using the counter-acting force and locking and fastening force between the lock body and the lock head and the connection of the bolt holes and threaded reinforcing steel bars, and connection fastness is improved.

Description

technical field

[0001] The invention relates to a steel bar connector, in particular to an ellipsoidal steel bar connector inside two structures of an assembled concrete structure. Background technique

[0002] There are many ways to connect prefabricated components, but it is mainly through the connection of steel bars in prefabricated components to realize the assembly connection between components. Reinforcement overlap obviously cannot meet the needs of prefabricated component assembly. For the welded connection of steel bars, the welding process also requires a large manual operation gap between the components, and the welding time is long, and the support of the components is very difficult, and the firmness of the joint depends largely on the firmness of the welding. Therefore, mechanical connection has become the only solution. At present, mechanical connection in cast-in-place concrete is mainly straight thread connection, cold extrusion connection, and taper threa...
