Pulling-resistant non-shearing-resistant connecting piece and construction method
The invention discloses a pulling-resistant non-shearing-resistant connecting piece and a construction method, the pulling-resistant non-shearing-resistant connecting piece comprises a toggle pin, a sleeve, an upper gasket and a lower gasket, the toggle pin is sleeved on the sleeve, the upper gasket and the lower gasket are respectively sleeved on two ends of the sleeve, the outer diameter of the middle part of the toggle pin is smaller than the inner diameter of the sleeve, the sleeve comprises a first semicircular pipe and a second semicircular pipe. The first semicircular pipe and the second semicircular pipe are oppositely arranged, the first semicircular pipe and the second semicircular pipe are formed in a spliced mode, flange edges are arranged at the two ends of the first semicircular pipe and the two ends of the second semicircular pipe, and the upper gasket and the lower gasket are located at the inner ends of the flange edges. The outer diameter of the middle of the toggle pin of the connecting piece is smaller than the inner diameter of the sleeve, the toggle pin is changed into the middle reserved space to be combined with the sleeve, concrete interacts with the connecting piece, the sleeve is deformed, the concrete is squeezed into the reserved space, and therefore the anti-pulling strength of a bridge deck slab and a steel beam is enhanced.
本发明公开了一种抗拔不抗剪的连接件及施工方法，包括栓钉、套管、上垫片和下垫片，所述栓钉套接于套管，所述上垫片和下垫片分别套接于套管的两端，所述栓钉的中部的外径小于套管的内径，所述套管包括第一半圆管和第二半圆管，所述第一半圆管和第二半圆管相对设置，且所述第一半圆管和第二半圆管拼接成型，所述第一半圆管和第二半圆管的两端均设有法兰边，所述上垫片和下垫片均位于法兰边的内端。此连接件的栓钉的中部的外径小于套管的内径，将栓钉改为中部预留空间与套管结合，使混凝土与连接件之间相互作用，导致套管变形，让混凝土挤压至预留空间内，从而增强了桥面板与钢梁的抗拔强度。
