Description
Technical Field
The utility model relates to a device for connecting reinforcing steel bars in a building structure.
Background
The mechanical connection mode of the reinforcing steel bars in the existing building structure mainly comprises cold extrusion connection and threaded connection.
The cold extrusion connection is to adopt a steel sleeve with high ductility and moderate strength, and the steel sleeve is subjected to plastic deformation by extruding the outer circle of the steel sleeve, so that the inner hole of the steel sleeve tightly grips the ribbed steel bar, and the connection of the two ribbed steel bars is realized.
The threaded connection comprises conical threaded connection, upsetting straight threaded connection and rolling straight threaded connection, two steel bars which are connected are processed through special equipment, a steel bar thread head with corresponding threads is manufactured at the end parts of the two steel bars, and the two steel bars are connected through a connecting sleeve with corresponding internal threads, so that the steel bar connection is realized. When in connection, the connecting sleeve is screwed into one steel bar wire head, and then the other steel bar is screwed into the sleeve and screwed, so that the force is transferred to the connection of the two steel bars, and at least one steel bar needs to rotate or axially move in the connection process, so that the existing steel bar connection mode is only suitable for the connection of a single steel bar.
With the development of the building industry, the building construction technology is continuously improved, and reinforcement part construction is gradually adopted in the building construction, namely, before reinforcement connection construction, a plurality of reinforcements are manufactured into an integral reinforcement mesh and reinforcement cage, and then reinforcement part integral connection is carried out. In the connection construction of the steel bar parts, the steel bars can only move along the axial direction and cannot rotate or move locally. Therefore, the existing reinforcement bar connection method cannot be used for realizing the integral connection of reinforcement bar parts. If the assembly type construction technology is being greatly popularized at present, the exposed steel bars of the components cannot rotate, so that the existing steel bar mechanical connection technology cannot realize steel bar connection, the steel bar connection between the components in the assembly type construction can only be realized by using a grouting sleeve, the construction cost of the grouting sleeve is high, the construction process is complicated, the construction quality is directly influenced by the engineering quality, and the steel bar connection quality is difficult to ensure.
