Chongqing steel pipe frame construction can be composed of single and double row scaffolding, support frame, support column, material lifting frame, climbing scaffold, cantilever frame and other functions according to specific construction requirements. . It can also be used to construct structures such as facility sheds, sheds, and lighthouses. Particularly suitable for setting up curved scaffolds and heavy-duty support frames.
The common rod is 3130mm long and weighs 17.07kg. The entire assembly and disassembly speed is 3 to 5 times faster than conventional, and the assembly and disassembly is fast and labor-saving. Workers can complete all operations with a hammer, avoiding many inconveniences caused by bolt operation.
The main components are all steel pipes of ordinary fastener-type steel pipe scaffolding, which can be connected with ordinary steel pipes by fasteners, and has high versatility.
The vertical pole connection is a coaxial socket, and the horizontal pole is connected to the vertical pole by a bowl buckle joint. The joint has reliable bending, shear, and torsional mechanical properties. Moreover, the axis of each member intersects at one point, and the nodes are in the plane of the frame. Therefore, the structure is stable and reliable, and the bearing capacity is large. (The bearing capacity of the whole frame is improved, which is about 15% higher than the fastener steel pipe scaffold of the same condition.)
When designing the joint, taking into account the spiral friction of the upper bowl buckle and the effect of self-gravity, the joint has a reliable self-locking ability. The load acting on the horizontal bar is transmitted to the vertical bar through the lower bowl buckle, which has a strong shear resistance. Even if the upper bowl buckle is not compressed, the crossbar joint will not come off and cause an accident. It is also equipped with a net support, cross bars, scaffolding, footboards, and ladders. Cantilever, pole and other pole accessories, reliable use. Working principle of bowl buckle scaffolding
The main component is Φ48 × 3.5, Q235B welded steel pipe. The manufacturing process is simple and the cost is moderate. The existing fastener-type scaffold can be directly processed and transformed. No complicated processing equipment is required.
