Anti-pulling connecting piece for wood structure building and mounting method of anti-pulling connecting piece

LIU YUFENG / JIN JINGYU / PAN JINLONG

The invention discloses an anti-pulling connecting piece for a wood structure building and a mounting method of the anti-pulling connecting piece. The connecting piece comprises an anchor bolt, and abelt wing, a bottom plate and an adjusting base plate are sequentially arranged on the anchor bolt from bottom to top along the axis of the anchor bolt, wherein a plurality of round holes are formed in the belt wing, and a conversion device for offsetting lateral force is arranged in the bottom plate. According to the anti-pulling connecting piece for the wood structure building and the mounting method of the anti-pulling connecting piece, the conversion device is arranged in the bottom plate, the conversion device takes the lateral force acting on a wall, namely the lateral force borne by thetop of the anchor bolt, as a reference point, and when it is detected that the lateral force exists in one direction, the upward abutting force is generated on the opposite side with the axis of theanchor bolt as the symmetry center, so that the lateral force is balanced; and the belt wing directly acts on the bottom of the wooden wall, and the connecting piece is not eccentric when stressed, sothat the pulling resistance of the anchor bolt and the connecting piece is improved, and the service life of the connecting piece is prolonged.

本发明公开了一种木结构建筑用抗拔连接件及其安装方法，包括锚栓，所述锚栓上沿其轴线从下往上依次设置有带翼、底板和调整垫板，所述带翼上设置有多组圆孔，所述底板内设置有抵消侧向力的转换装置，此木结构建筑用抗拔连接件及其安装方法，通过在底板内设置转换装置，转换装置通过作用在墙体上的侧向力即锚栓顶部受到的侧向力作为依据点，在检测到一个方向有侧向力时，通过在以锚栓轴线为对称中心的相反的一侧产生向上的抵触力，从而对侧向力进行平衡，且带翼直接作用于木墙体的底部，连接件受力不产生偏心，提高了锚栓以及连接件的抗拔性，且延长其使用寿命。
