The buckle scaffold uses discs and pins instead of fasteners. The pole of the buckle type scaffold is equipped with a circular disc, and the pole, crossbar, and diagonal rod connections are all connected by pins, saving the time of fastener connection and making installation and erection very convenient.
Today, I will introduce to you the deformation remediation methods for buckle type scaffolding:
1. Local deformation of scaffolding caused by foundation settlement. During the construction process at the construction site, if the scaffold deforms due to the settlement of the foundation, the foundation under the scaffold needs to be compacted first, and then the cross-section of the double bending frame needs to be erected on the cross-section of the double bending frame. To the outer layer of the deformation zone. Constellation or scissor support must be set on a solid and reliable foundation.
2. The deflection and deformation of the cantilever steel beams used for scaffolding exceed the specified values. The anchorage point behind the cantilever steel beam should be reinforced, and the steel beam should be fastened with steel supports and U-shaped brackets to support the roof. There is a gap between the embedded steel ring and the steel beam, which must be fixed with a wedge. Inspect the steel wire ropes at the outer end of the suspended steel beam one by one and tighten them all to ensure even force distribution.
3. When unloading the buckle type scaffold, if the connection system is partially damaged, it must be immediately restored according to the unloading method determined in the original plan, and the deformed parts and components must be corrected. If the deformation of the scaffold is corrected outward, first set a 5-ton winding chain at each interval, tighten the structure, loosen the rigid tension point, and tighten the winding chain inward at all points until the deformation is corrected and the rigid tension is completed. Connect and tighten the steel wire rope at each unloading point to evenly distribute the force, and then loosen the chain.
Unlike traditional scaffolding, the pole raw material of the buckle type scaffolding adopts Q345b first-class standard steel pipe, which has high load-bearing capacity and stable performance. The hot-dip galvanizing anti-corrosion process slows down the oxidation rate of the steel pipe, making the service life of the product reach more than 20 years. The lap joint and disassembly speed of the buckle type scaffold is quite fast, abandoning traditional bolt fasteners and bowl buckle frames that need to be covered with buckles. This allows the lap joint speed of the buckle frame to reach 8 times that of steel pipe fasteners and more than 3 times that of bowl buckle frames. Due to the connection between the upright and horizontal poles, it can be fastened by the self weight of the horizontal pole plug and the worker's hammer. Although deformation accidents of scaffolding cannot be avoided, buckle scaffolding is safer.
Characteristics of buckle scaffolding
1. Multi functional: According to specific construction requirements, it can form single row, double row scaffolding, support frames, support columns, and other construction equipment with multiple module sizes and loads of 0.5m, and can be arranged in curves.
2. Less structure, easy to build and dismantle: The basic structure and specialized components make the system adaptable to various structural buildings.
3. Economy, saving labor costs: The construction splicing speed is 0.5 times faster than that of bowl buckle scaffolding, reducing labor time and labor remuneration, and reducing transportation costs to lower overall costs.
4. The joint structure is reasonable, easy to operate, lightweight and convenient.
5. High bearing capacity: The axial force transmission of the upright pole enables the scaffold to have high structural strength and overall stability in three-dimensional space. The circular plate has reliable axial shear resistance, and the axes of various members intersect at one point, resulting in an overall stability strength 200% higher than that of bowl buckle scaffolding.
6. High safety: adopting an independent wedge inserted self-locking structure. Due to interlocking and gravity, even if the pin is not tightened, the horizontal bar plug cannot be removed. The plug-in has a self-locking function, which can be locked or removed by pressing the pin. In addition, the contact surface between the fastener and the support is large, which improves the bending strength of the steel pipe and ensures that the support will not tilt when combined.
7. Good comprehensive benefits: standardized component series for easy transportation management. No scattered and easily lost components, low loss, and minimal investment in the later stage.
