Friction type double-thread connecting assembly and fabricated building
The invention discloses a friction-type double-thread connecting assembly and a fabricated building, relates to the field of prefabricated concrete pile connecting components, and aims to solve the problem that an existing connecting structure is insufficient in tension and ductility. The friction-type double-thread connecting assembly is characterized in that a middle nut and a combined nut are mounted in a sleeve, the middle nut is fixed to the inner wall of an opening of the sleeve, and the combined nut is fixed to the inner wall of the opening of the sleeve; the inner wall of the middle nut is in a circular truncated cone shape, the narrow end of the middle nut is located at the opening, the outer walls of the combined nuts abut against the inner wall of the middle nut and can slide relatively, the at least two combined nuts are evenly distributed on the inner surface of the middle nut, and a gap is formed between every two adjacent combined nuts. Threads are arranged on the inner wall of the combined nut and matched with external threads of the threaded friction rod, and an elastic piece is arranged in the sleeve and used for abutting against the combined nut. According to the scheme, the large meshing force can be formed, the connecting strength and the tensile force are improved, meanwhile, ductile failure can be achieved under the displacement condition, the building safety is guaranteed, and the requirement for building engineering assembly is met.
本发明公开了一种摩擦型双螺纹连接组件及装配式建筑，涉及预制混凝土桩连接构件领域，旨在解决目前的连接结构受拉和延性不足的问题，其技术方案要点：套筒内安装有中间螺母以及组合螺母，中间螺母固定在套筒开口处的内壁，中间螺母内壁呈圆台状设置且较窄的一端位于开口处，组合螺母外壁抵触在中间螺母的内壁且能够发生相对滑动，组合螺母设置有至少两个且均匀分布在中间螺母的内表面，相邻组合螺母之间有间隙，组合螺母的内壁有螺纹且与螺纹摩擦杆的外螺纹适配，套筒内设置有弹性件用于抵触组合螺母。本发明的方案能够形成较大的咬合力，提高连接强度和受拉力，同时在发生位移情况下可以延性破坏，保证建筑安全，满足建筑工程组装的需要。
