Background

The disk-buckle type scaffold technology originates from Germany and is a mainstream product in Europe and America, a support frame is divided into upright rods, cross rods and inclined rods, eight holes are formed in a disk, four small holes are special for the cross rods, and four large holes are special for the inclined rods. The connection mode of the cross rod and the inclined rod is a bolt type, so that the rod piece and the vertical rod can be firmly connected. The cross bar and diagonal bar joints are made according to the circular arc of the pipe, and are in whole-surface contact with the vertical steel pipe, after the bolt is knocked down, three-point stress (two points above and below the joint and one point of the bolt to the disc) is formed, so that the structural strength can be firmly fixed, the horizontal force can be transmitted, the cross bar head and the steel pipe body are fixed by full welding, and the force transmission is correct. The inclined rod head is a rotatable joint, and the inclined rod head and the steel pipe body are fixed through rivets. As for the connection mode of the upright rods, the square tube connecting rod is taken as the main part, and the connecting rod is fixed on the upright rod without being combined by other joint components, thereby avoiding the troubles of material loss and arrangement.

The connecting disc on the disc-buckled scaffold is fixed with the steel pipe through welding, and the shear strength of the connecting disc and the steel pipe determines the strength limit of the disc-buckled scaffold when the external force is vertical to the axis of the material. The existing disk-buckled scaffold exerts pressure on pipe fittings at two ends of a connecting disk by using a hydraulic cylinder to observe a test result when the strength limit of the existing disk-buckled scaffold is subjected to shearing action.
