Scaffolding should be used for construction personnel to work up and down or to protect the outer safety net and its high-altitude installation components, that is, to safely set up the scaffolding. The scaffolding materials generally include bamboo, wood, steel pipe, or other related components. Some projects use scaffolding as templates. Also, scaffolding is widely used in advertising, municipal transportation, roads, bridges, and mines.
Scaffolding is often used in construction. When using scaffolding, there will inevitably be such questions. Let’s take a look at some questions that scaffolding presents in construction. These questions are emergency measures. The scaffold part is deformed due to the settlement of the foundation. On the horizontal cross-section of the double-breasted frame, set up a horoscope or scissor brace, and set up a set of vertical rods every other row until the outer row of the deformation zone. The horoscope or scissor support must be set on a solid and firm foundation. The deflection and deformation of the cantilevered steel beam on which the scaffolding is used exceed the specified value. The anchorage point of the cantilevered steel beam should be reinforced, and the steel beam should be tightened with steel supports and corresponding supports to withstand the roof. There is an open space between the embedded steel ring and the steel beam, and the horse wedge is used to prepare it. The wire ropes hanging from the outer ends of the steel beams are checked one by one, and the scaffolds are all tightened to ensure uniform force. The unloading and tensioning system part of the scaffolding in use are damaged, immediately follow the unloading and tensioning method is drawn up in the original plan to recover it and correct the deformed parts and members. To correct the deformation of the scaffolding outward expansion, first set up the inverted chain according to each bay, tighten the same structure, loosen the rigid pull contact, and tighten the inverted chain inward at each point at the same time, the deformation is corrected, and the rigid pull connection is completed. , And tighten the wire ropes at each unloading point to unwind the chain.
