1results about How to "Shear resistance" patented technology

This utility model relates to an embedded steel-clad wood-concrete composite beam, belonging to the field of composite beam technology. It includes a concrete slab with a trapezoidal groove extending along its length at the bottom. A wooden beam is positioned below the concrete slab, and the wooden beam has trapezoidal protrusions that mate with the groove, inserted into the groove. Several shear pins are arranged along the length of the wooden beam, fixing it to the upper part. An outer steel beam with a rectangular cavity is positioned below the concrete slab, and the wooden beam is embedded within this cavity. Two sets of barbed bolts are provided on the concrete slab, located on opposite sides of the trapezoidal groove. This utility model utilizes the compressive strength of steel and the tensile strength of wood in synergy, achieving efficient connection through mortise and tenon joints, pins, and bolts, enhancing overall load-bearing capacity and stability. It is suitable for large spans and negative bending moment areas, possessing excellent assembly adaptability and durability.
