Title:
DRY CONNECTION PREFABRICATED ASSEMBLY STEEL-CONCRETE COMPOSITE BEAM
Document Type and Number:
WIPO Patent Application WO/2018/196376
Kind Code:
A1
Abstract:
A dry connection prefabricated assembly steel-concrete composite beam, comprising a steel beam (400), a concrete slab (300) composed of steel bars (301) and concrete, a steel plate connector (100) composed of a steel plate (101), shear connection pieces (102) and connection rods (103), and a pair of inter-plate connection pieces respectively composed of an upper connection plate (501), a lower connection plate (502), a horizontal connection plate (503), a triangular reinforcing steel plate (504) and first and second shear connection pieces (505, 507). An upper surface of each horizontal connection plate (503) is vertically connected to the upper connection plate (501) and the first shear connection pieces (505), a lower surface is vertically connected to the lower connection plate (502), the triangular reinforcing steel plate (504) is welded between a lower surface of the horizontal connection plate (503) and a side surface of the lower connection plate, and one side surface of the upper connection plate (501) is horizontally connected to the second shear connection pieces (507). Both ends of the steel bars (301), which are laterally preset within the concrete slab (300), are provided with screw threads, and the screw thread ends of the steel bars respectively pass through bolt holes (509) and work holes (5010) arranged at upper ends of the upper connection plates (501) to be fixedly connected via screw nuts (302). The composite beam reduces on-site workload, and facilitates disassembly.
