Description

Connecting structure of steel beam and steel bar

Technical Field

The invention relates to the field of steel structures, in particular to a connecting structure of a steel beam and a steel bar.

Background

With the acceleration of urbanization process, the shapes and functions of building engineering are increasingly diversified and complicated. When common girder steel is connected with the reinforcing bar, beat the hole earlier on the web of girder steel usually, then pass the hole with the reinforcing bar, again with reinforcing bar and girder steel welding together, the web of girder steel will beat the hole, this intensity requirement to the girder steel is higher, the hole that the reinforcing bar passed the girder steel welds together again, the later stage of being inconvenient demolish, influence work efficiency.

In the prior art, some improvements are made to the above problems, for example, the invention patent with the chinese patent No. 201220682244.9 provides a connection structure of a reinforced concrete beam and a steel beam combination for foundation pit support, which includes a reinforced concrete beam and a steel beam, and is characterized in that a pre-embedded nut is arranged in the reinforced concrete beam, one end of the nut is connected with a pre-embedded bolt or a steel bar, and the other end of the nut is tightly attached to the steel beam and is connected with the steel beam through a detachable screw rod. This technical scheme, although subsequent demolish of being convenient for, the position of pre-buried nut is fixed, and the installation in-process of being not convenient for makes appropriate adjustment according to actual need, and accommodation is little, reduces work efficiency.

To this end, chinese patent application No. 201610186578X, granted publication No. CN105804327B discloses that the following problems existing in the above-mentioned published technologies can be effectively overcome: the connecting block in the technology is clamped on a flange plate of a steel beam through two sliding grooves on the connecting block, the steel beam and the connecting block are fixed in an attempt of tightening a locking screw mode, and because the connecting block is of an integral structure, the two sliding grooves on the connecting block have inevitable errors in the manufacturing process, the matching between the sliding grooves and the flange plate has errors, the phenomenon of over-positioning in the process is caused, the fixing is not firm, and safety accidents are caused.
