Description

Technical Field

[0002] H-shaped steel beams, consisting of an upper flange, a lower flange, and a web, are widely used in various civil and industrial building structures. During on-site installation of steel structures, excessively long beams require a segmented, spliced ​​structure. To reduce welding work on the construction site, a fully bolted connection method is currently commonly used. This involves pre-setting connection holes in the upper flange, lower flange, and web of the two steel beam sections to be connected, and then bolts and connecting plates are used to connect the two sections. However, in actual construction, this method often results in the steel beams being too long or too short due to insufficient manufacturing precision or thermal expansion and contraction, resulting in misaligned bolt holes and connection failures. Alternatively, on-site hole enlargement is required to complete the connection, which not only slows down construction but also reduces the bearing capacity of the connection, compromising structural safety.
