Title:
BOXBOARD PREFABRICATED STEEL STRUCTURE BUILDING UNIT WITH COMBINED BOLTS AND WELDING, AND CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/016412
Kind Code:
A1
Abstract:
Disclosed in the present invention are a boxboard prefabricated steel structure building unit with combined bolts and welding, and a construction method. The building unit comprises a plurality of steel plate walls and steel floor slabs, wherein each steel plate wall is formed by connecting a plurality of wall steel plate blocks, and the plurality of steel plate walls are laterally connected to form a wall structure; stiffening ribs are uniformly arranged on inner sides of the wall steel plate blocks and on bottom sides of the steel floor slabs, and are welded to wall steel plates in a discontinuous welding manner; corner connectors are used for bolt connections between the wall steel plate blocks, between the steel plate walls, and between the steel floor slabs and corresponding steel plate walls; the discontinuous welding is used for repair welding between the corner connectors, between the corner connectors and the wall steel plate blocks, between the corner connectors and the steel plate walls, and between the corner connectors and the steel floor slabs; and door and window openings are reserved in the wall steel plate blocks according to design requirements. The present invention enables a connection using combined bolts and welding, which can effectively reduce the effect of residual stresses generated due to welding on the structural performance, thereby providing relatively enhanced safety.
