A seismic joint support for steel structure engineering

Abstract

This invention provides a seismic joint support for steel structure engineering in the field of seismic joint support technology, comprising: a hanger and a rod. The hanger is fixedly connected to the hanger beam by bolts, and the rod is fixedly connected to the bottom of the steel structure by expansion bolts. The hanger is a C-shaped steel, and inserts are inserted into both sides of the hanger. The top of the insert is threaded with a limit screw, and a limit block is slidably connected inside the insert. One side of the limit block is semi-circular, and the other side is rotatably connected to an adjusting rod threadedly connected to the insert. An adjusting groove is opened at the tail of the adjusting rod. Connecting plates are fixedly connected to both sides of the insert, and fixing bolts are threadedly connected to the connecting plates. Insert plates are provided between the fixing bolts and the connecting plates, and a base is fixedly connected between the insert plates. It can be assembled and used with ordinary supports, avoiding the messy roof of old buildings caused by renovation, increasing the difficulty of maintenance of electromechanical facilities, reducing the number of openings, and preventing the stability of old buildings from being affected.
