technical field

The utility model relates to the technical field of steel structures, in particular to a novel supporting H-shaped steel beam-column structure.

Background technique

H-beam corner braces (horizontal bracing) are provided to prevent buckling and instability of H-beam compression flanges (lower flanges of H-beams) and increase the stability of the compression flanges. The setting is used to ensure the local stability of the compression part of the lower flange of the beam, and the local stability of the upper flange of the beam is ensured by the floor slab connected to it (the upper flange of the H-beam has studs, which are connected with the concrete floor). The slab is cast as a whole), so there is no overall stability problem for the upper flange of the beam.

The existing H-shaped steel beam support structure, including the corner bracing and the haunch, are exposed under the floor slab, which can be seen by almost every household on every floor. To a large extent, the construction cost is increased, so it is very necessary to propose a new type of support H-shaped steel beam-column structure to solve the above problems.
