In addition, also corresponding offering can be for passing bolt T-connecting piece, H shape girder steel be fixedly connected on the hand hole in the outside of square steel tube post on square steel tube post jamb described in the utility model and the outer tube tube wall, described hand hole position be provided with install be used to after T-connecting piece and the H shape girder steel to seal, steel plate that repair welding is used.
The beneficial effects of the utility model
1. the utility model adopts the high-strength bolt type of attachment, reduces even avoid the weld job of job site, has significantly reduced the quality accident that causes because of weld defect, the fire that reduces or avoided causing because of welding spark.Simultaneously, owing to adopt bolt to connect, speed of application also has raising by a relatively large margin.
2. because T-connecting piece is provided with floor, can resist shearing force, can not need between the web of H shape girder steel and the square steel tube to connect.In addition, above-mentioned T-connecting piece is compared with existing angle steel or L shaped angle steel, and the energy force rate opposing vertical forces of opposing horizontal pull, pressure is bigger, and the sled power that produces in the T-connecting piece end is compared and can be reduced.
Since the square steel tube post before transporting the job site to, node region has only added an outer tube, compares with traditional joint form, transports more convenient.
4. the connected node of the utility model square steel tube post and H shape girder steel, because node region is not provided with internal partition, therefore, for need also being very useful in the situation of steel duct concreting.
