Anti-pulling and non-anti-shearing integrated self-locking type shear nail connecting piece
The invention discloses an anti-pulling and non-anti-shearing integrated self-locking type shear nail connecting piece which comprises a stud, a stud body and a top cap of the stud are sleeved with a self-locking type stud body protection ring and a self-locking type stud cap protection ring respectively, and the upper portion and the lower portion of the self-locking type stud body protection ring are each provided with a hollow protection ring. The upper protection ring and the lower protection ring form an angle of 45 degrees with the stud body of the stud, an opening area is arranged on the side wall of the self-locking type stud body protection ring, and meshing edges are arranged on the two sides of the self-locking type stud body protection ring. On the basis of a traditional stud, the stud body protection ring and the stud cap protection ring are additionally arranged, deformation cavity areas are formed on the peripheries of the stud body and the stud cap at the same time, and after a concrete floor slab is hardened, the cavity areas are formed between the stud and the floor slab so that small-range horizontal dislocation between the floor slab and the stud can be achieved. The hogging moment section local release steel beam and concrete floor combination effect is achieved, and the concrete floor cracking problem is effectively relieved.
本发明公开了一种抗拔不抗剪一体自锁式剪力钉连接件，包括栓钉，所述栓钉的钉身和顶帽外分别套设有自锁式钉身保护环和自锁式钉帽保护环，所述自锁式钉身保护环上下各设置有一个中空的保护环，上下两个保护环均与栓钉的钉身呈45°角，所述自锁式钉身保护环侧壁设有一个开口区，两侧设置咬合边。本发明在传统栓钉基础上通过增加钉身保护环与钉帽保护环，对钉身与钉帽四周同时形成变形空腔区，可实现混凝土楼板硬化后，栓钉与楼板间形成空腔区以实现楼板与栓钉间小范围水平向错动。实现负弯矩区段局部释放钢梁与混凝土楼板组合作用，有效缓解混凝土楼板开裂问题。
