Knowledge points about wheel-buckle scaffolding: Wheel-buckle scaffolding is a new type of convenient support scaffolding. It is somewhat similar to a bowl-buckle scaffolding but is better than a bowl-buckle scaffolding. Its main features are:
1. It has reliable two-way self-locking ability;
2. No moving parts;
3. Transportation, storage, erection, and dismantling are convenient and fast;
4. Reasonable force performance;
5. Can be adjusted freely;
6. Product standardized packaging;
7. Reasonable assembly, its safety, and stability are better than the bowl-buckle type and better than the portal type scaffolding;
8. Practice has shown that as a single-span, multi-span continuous beam, and frame structure house formwork support system with a beam span of less than 15m and a clearance height of less than 12m, its stability and safety are better than that of bowl-buckle scaffolding, and better than that of bowl-buckle scaffolding. Portal scaffolding.
Construction points:
1. A special construction plan for the support system should be designed in the early stage, and the general contractor should lay out the lines and position the support system horizontally and vertically to ensure the later setting of scissor braces and integral connecting rods to ensure its overall stability and resistance to overturning.
2. The installation foundation of wheel-buckle scaffolding must be compacted and leveled and concrete hardening measures must be taken.
3. Wheel-buckle scaffolding should use the elevation range of beams, slabs, and base plates at the same elevation. When using a single-component support frame with a large height and span, check the tension of the crossbar and the axial pressure (critical force) of the vertical bar to ensure The stability and safety of the frame.
4. After the erection of the frame is completed, sufficient scissor braces should be added, and sufficient horizontal tie rods should be added at a distance of 300-500mm between the top bracket and the frame crossbar to ensure that the overall stability is reliably guaranteed;
5. At present, the Ministry of Construction of our country has not issued industry standards and specifications for wheel-clamp scaffolding, but it has begun to be widely used on construction sites. Of course, we hope that relevant departments will formulate corresponding specifications so that wheel-clamp scaffolding can be used correctly in projects. reliable basis.
