Self-hole-forming and self-tapping shearing force connection piece and construction method thereof

Abstract

The invention discloses a self-hole-forming and self-tapping shearing force connection piece and a construction method thereof. By means of the self-hole-forming and self-tapping shearing force connection piece, a laminated wood beam and a light-weight aggregate concrete flange are combined together. The self-hole-forming and self-tapping shearing force connection piece comprises a drill bit, a chip storage groove, a thread, a limiting joint, a nail rod and a hexagon head. The nail rod comprises a smooth section and a threaded section. The smooth section is poured in the bottom face of the light-weight aggregate concrete flange, and the threaded section is nailed into the top face of the laminated wood beam. The limiting joint capable of controlling the depth by which the shearing force connection piece is embedded in wood at any embedding angle is arranged between the smooth section and the threaded section. The self-hole-forming and self-tapping shearing force connection piece can be applied to floors and roofs of houses, landscape architecture and bridges of garden scenic regions and other structures.

Description

technical field [0001] The invention relates to a building structure component, in particular to a self-opening self-tapping shear connector and a construction method thereof, which can be applied to the interlayer shear connection of wood and concrete, and belongs to the technical field of building structures. Background technique [0002] Compared with other building materials, wood is highly anisotropic, has low bearing capacity, poor fire resistance, and has many natural defects, such as the distribution of wood knots in it greatly reduces the strength of wood, and logs are prone to decay, discoloration and insects. termite. Traditional wooden structures using wood as the only load-bearing material cannot overcome the above disadvantages, resulting in low strength, rigidity and poor fire resistance reliability of wooden structures. When the wood structure building has a deep bay and a large load, it is often necessary to use a structural layout with dense columns and de...

AI Technical Summary

Problems solved by technology

This kind of composite beam is an improvement to traditional wooden beams and reinforced concrete beams, but because a series of transverse grooves need to be made on the wooden beams during the construction process, the effective section of the wooden beams will be greatly weakened and the load capacity of the composite beams will be reduced. capacity, and steel rods still need to be arranged after slotting, the construction is very complicated
