Anti-bending and anti-pulling mortise and tenon joint type scaffold node
The invention discloses an anti-bending and anti-pulling mortise and tenon joint type scaffold node which comprises mortise steel casting and tenon steel casting. A circular body is arranged on the mortise steel casting and provided with a big-end-up wedge-shaped mortise. A disc connecting plate is arranged on the tenon steel casting and provided with a big-end-up wedge-shaped tenon. The wedge-shaped tenon is inserted in the wedge-shaped mortise in a matched mode. Necking limiting plates extending into the mortise are arranged on the two sides of a lateral opening of the wedge-shaped mortise respectively. Rib plates extending outwards are arranged on the two sides of the outer end of the wedge-shaped tenon respectively. The rib plates and the necking limiting plates are staggered in an inside-outside mode and meshed in a concave-convex mode. By means of the structure that the rib plates of the tenon and the necking limiting plates of the mortise are staggered in the inside-outside mode and meshed in the concave-convex mode, a scaffold transverse rod is restrained from moving out of the node, the node is high in anti-pulling and anti-bending bearing capacity, the safety coefficient is high, and safety accidents can be effectively reduced.
