Problems solved by technology

When the relevant provisions of these codes are applied to the H-shaped steel connection joints, if the section height of the H-shaped steel beam is less than 250mm, the web height of the H-shaped steel will be difficult to meet all the structural requirements of high-strength bolts.
In engineering practice, in order to avoid the above situation, the cross-sectional height of the H-shaped steel beam is often not less than 250mm, or if the cross-sectional height of the H-shaped steel beam is less than 250mm, only on-site welding can be used to connect the nodes, which will bring construction period Shortcomings such as length and quality are difficult to guarantee. In the prior art, the cross-sectional size of H-shaped steel beams is determined by the structure of the end connection nodes rather than the strength and stiffness of the members. H-shaped steel beams cause unnecessary waste and also hinder the engineering application of H-shaped steel beams with small cross-sectional heights

Abstract

The invention discloses an H-shaped steel beam connecting node, which comprises a main beam and a secondary beam. Protruding gusset plates of a web plate of the main beam and a web plate of the secondary beam are connected through a high strength bolt; an upper flange or a lower flange of the secondary beam is retracted, and the exposed part of the web plate of the retracted secondary beam is connected with a first steel plate; and the first steel plate is on the same plane with the web plate of the secondary beam, and is used as a node area with the exposed part of the web plate of the secondary beam and connected with the protruding gusset plates of web plate of the main beam through the high strength bolt. In the H-shaped steel beam connecting node provided by the invention, because the height of the node area of the web plate of the H-shaped steel beam is enlarged, the H-shaped steel beam with a small section is possibly connected by adopting the high strength bolt, the disadvantages brought by on-site welding and connecting modes are avoided, and the problem that the H-shaped steel beam with the small section cannot be applied due to the structure of the main beam and secondary beam connecting node so as to cause waste is solved.
