Tangshan Yining Mould Co., Ltd. specializes in the production of disc-type scaffolding, which is a manufacturer of disc buckle scaffolding, production, leasing, sales, design and construction. The button-type scaffolding technology originated in Germany and is the mainstream product in Europe and America. The support frame is divided into vertical poles and crossbars and diagonal poles. There are eight holes on the disc, four small holes are dedicated for the crossbar; four large The hole is dedicated to the slanting rod. The connection method of the cross bar and the diagonal bar is a pin type, which ensures that the rod and the pole are firmly connected. The cross bar and the slant bar joint are specially made according to the circular arc of the pipe, and are in full surface contact with the vertical steel pipe. After the bolt is tightened, the force is applied at three points (the upper and lower points of the joint and the pin to the disc) can be firmly fixed and increased. The structural strength and the horizontal force are transmitted, and the crosshead and the steel pipe body are fixed by full welding, and the force transmission is correct. The slanting head is a rotatable joint, and the slanting head is fixed to the steel pipe body by rivets. As for the connection method of the poles, the square bar connecting rods are mainly used, and the connecting rods are fixed on the poles, and the joints are not used to combine, which can save the trouble of material loss and finishing.
