Connection structure of crane girder and bracket

The utility model discloses a connection structure of crane girder and bracket, including crane girder and the bracket of setting on the framed bent post, has arranged pre -buried steel sheet of bracket and the pre -buried steel sheet of crane girder between bracket and the crane girder, arranged a plurality of joint bars on the bracket, the anchor was gone into in the crane girder after the joint bar passed pre -buried steel sheet of bracket and the pre -buried steel sheet of crane girder respectively, the crane girder is cast -in -place continuous crane girder to, the bracket builds after building the completion, the lacing wire has been put to pre -buried steel sheet of crane girder and bracket pre -buried steel backboard face equipartition, all be equipped with the thru hole that the diameter slightly is greater than the joint bar on pre -buried steel sheet of crane girder and the pre -buried steel sheet of bracket. The utility model discloses a set up pre -buried steel sheet and joint bar simultaneously, both avoided the contact surface to take place the possibility that the superpressure was destroyed, again can effective resistance horizontal loading and the horizontal internal force of crane girder. Guaranteed that the bracket is reliable and stable with being connected of crane girder, be favorable to the factory building to stabilize the safe operation.
