Thin-wall buckling type pulling-resistant non-shearing-resistant stud connecting piece
The invention discloses a thin-wall buckling type pulling-resistant non-shearing-resistant stud connecting piece which comprises a stud, a stud body and a top cap of the stud are sleeved with a cavity protection pipe and a cavity plastic protection sleeve respectively, a nitrile rubber sleeve is arranged between the lower portion of the stud and the cavity protection pipe, and a limiting circular ring is arranged above the nitrile rubber sleeve. On the basis of a traditional stud, a hollow area is formed between the stud and the floor through the connecting piece, the connecting piece is pressed and bent through a thin wall to achieve small-range horizontal dislocation between the concrete floor and the stud, the tensile stress of a hogging moment area of a concrete slab is effectively released, and the cracking problem of the concrete floor is relieved; majority of matched parts are finished products in the market, construction is easy, installation is convenient, and good technical and economic benefits are achieved.
本发明公开了一种薄壁屈曲式抗拔不抗剪栓钉连接件，包括栓钉，所述栓钉的钉身和顶帽外分别套设有空腔保护管和空腔塑料保护套，所述栓钉的下部与空腔保护管之间设置有丁腈橡胶套，所述丁腈橡胶套上方设置有限位圆环。本发明在传统栓钉基础上通过连接件在栓钉与楼板间形成中空区域，连接件通过薄壁受压屈曲实现混凝土楼板与栓钉间小范围水平向错动，有效释放混凝土板负弯矩区的拉应力，缓解混凝土楼板开裂问题；取材方便，大部分配套零件市场上均具有成品，施工简单、安装方便，具有良好的技术经济效益。
