Description

Technical Field

[0001] The utility model relates to the technical field of large-span steel beams, in particular to a large-span H-shaped steel beam structure. Background Art

[0002] H-shaped steel, also known as steel beam, is a long steel bar with an H-shaped cross section. H-shaped steel is divided into ordinary H-shaped steel and light H-shaped steel. It is a steel with an H-shaped cross section. It belongs to the economical section steel and is rolled on a four-roll universal rolling mill, so it is also called "universal H-shaped steel". In order to meet the needs of the project, measures are often needed to achieve the large span construction of H-shaped steel beams.

[0003] For example, a reinforced steel connection structure disclosed in the authorization announcement number CN219547997U includes a steel beam, a steel column, and a connection structure installed between the steel beam and the steel column, wherein the connection structure includes a support cross block and a support vertical block, wherein the support cross block and the support vertical block are hinged, and the outer walls of the support cross block and the support vertical block that are away from each other are respectively fixedly connected to the steel beam and the steel column by bolts. This reinforced steel connection structure is achieved by setting the support cross block and the support vertical block to be hinged, and then adjusting the support cross block and the support vertical block according to the angle between the steel beam and the steel column and placing them at the connection between the steel beam and the steel column. At this time, the support cross block and the support vertical block are penetrated by bolts and fixed to the steel beam and the steel column, so that the connection between the steel beam and the steel column can be completed at different angles. However, the utility model lacks corner protection mechanisms and reinforcement measures at the connection, which is not convenient for ensuring the connection stability of the H-shaped steel beam. For this reason, we propose a large-span H-shaped steel beam structure, which adds reinforcement measures and corner protection mechanisms at the connection of the H-shaped steel beam, improves the stability and durability of the structure, and thus improves the practicality of the structure.
