The invention discloses a building scaffold fastener. The building scaffold fastener structurally comprises a buckle plate, a disengagement preventing device, an occlusion piece and a bolt rod. The building scaffold fastener has the beneficial effects that through cooperation of an arranged air protection structure and a resistance increasing mechanism, when the fastener and a scaffold accidentally disengage, the resistance increasing mechanism and the surface of a scaffold steel pipe are compactly attached through cooperation of upward rushing of airflow, then the contact friction coefficientbetween the resistance increasing mechanism and the surface of the scaffold steel pipe is increased, and the sharp falling speed of the building scaffold fastener is reduced; and through attachment of a grinding ball and an arc plate which are arranged in a matched manner and the surface of the scaffold, in the downward sliding process, a clamping plate conducts falling clamping on the surface ofthe scaffold during sliding, clamping between the clamping plate and the surface of the steel pipe is enhanced, and therefore acute disengagement of the fastener is avoided.
本发明公开了一种建筑脚手架扣件，其结构包括扣板、阻脱装置、咬合件、螺栓杆。有益效果：本发明利用设有的气护结构与加阻机构的配合，在扣件与脚手架发生意外的脱落时，配合气流的上冲使得加阻机构与脚手架钢管表面做紧凑贴合，继而提高二者间的接触摩擦系数，以减缓其急剧下落的速度，本发明配合设有的磨球和弧板与脚手架表面的贴合，在下滑的过程中，使得卡位板对脚手架表面做滑落时的下落卡位，加强与钢管表面的卡位，从而避免扣件出现急性的滑脱。
