Recombined bamboo-tapping screw wood-concrete shear connector and construction method thereof
The invention discloses a recombined bamboo-tapping screw wood-concrete shear connector and a construction method thereof, and relates to the technical field of novel structures of constructional engineering.The recombined bamboo-tapping screw wood-concrete shear connector comprises a concrete plate and laminated wood, a recombined bamboo plate is arranged between the bottom of the concrete plate and the top of the laminated wood, and a steel pipe sleeve is arranged at the top of the recombined bamboo plate in a penetrating mode; full-thread self-tapping screws are arranged at the four corners of the recombined bamboo board in a penetrating mode. A half-thread self-tapping screw is arranged in the steel pipe sleeve in a penetrating mode. Compared with a traditional wood-concrete structure node connection mode, the node connection mode and the construction mode are innovated, the steel sleeve and the half-thread self-tapping screw are adopted, external impact force can be effectively absorbed, and the protection effect is provided for the self-tapping screw; the inclined full-thread self-tapping screw is adopted, so that the screw can be effectively prevented from being bent and damaged, and meanwhile, higher anti-sliding rigidity is provided; the recombined bamboo board is embedded into the laminated wood, so that the shear bearing capacity of the combined beam can be improved, and cracking of the laminated wood caused by stress concentration can be effectively avoided.
本发明公开了一种重组竹‑自攻螺钉木混抗剪连接件及其施工方法，涉及建筑工程新型结构技术领域，包括混凝土板与胶合木，混凝土板底部与胶合木顶部之间设置有重组竹板，重组竹板顶部穿插设置有钢管套，重组竹板四角均穿插设置有全螺纹自攻螺钉；钢管套内部穿插设置有半螺纹自攻螺钉。本发明从节点连接形式和施工形式创新，与传统木‑混凝土结构节点连接形式相比，采用钢套管和半螺纹自攻螺钉，能够有效吸收外部冲击力并为自攻螺钉提供保护作用；采用倾斜全螺纹自攻螺钉，能够有效避免螺钉发生弯曲破坏，同时提供较高的抗滑移刚度；采用重组竹板嵌入胶合木，不仅能提高组合梁的抗剪承载力，还能有效避免由应力集中而引起的胶合木开裂。
