Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to an anti-dumping scaffold for bridge, road and building construction and a construction method. Background Art

[0002] Anti-dumping scaffolding plays a vital role in bridge, road and building construction. Its main functions are reflected in the following aspects: 1) Providing stable support: The construction of bridges and roads often involves high-altitude operations, and a stable support structure is required to ensure the safe construction. The anti-dumping scaffolding provides a stable working platform for construction workers through its sturdy structure and connection method, effectively preventing the risk of scaffolding collapse caused by construction vibration, wind and other factors. 2) Ensure construction safety: In bridge and road construction, the safety of workers is of vital importance. The anti-dumping scaffolding effectively prevents the risk of workers falling from heights through its design, such as adding guardrails and anti-slip devices. At the same time, it can also provide a certain amount of buffering and support when workers fall, reducing the degree of injury. 3) Improve construction efficiency: The construction of anti-dumping scaffolding provides construction workers with a more convenient and efficient working environment. Workers can carry out various construction operations on the scaffolding, such as installing formwork, pouring concrete, etc., without frequent movement or adjustment of positions, thereby greatly improving construction efficiency. 4) Prevent scaffolding from tipping over: Especially in bridge construction, due to the high height of the scaffolding, once it tips over, it will pose a great threat to the construction workers and on-site equipment. Anti-tipping scaffolding effectively improves the overall stability of the scaffolding by adding anti-tipping devices and strengthening connections, and prevents the risk of the scaffolding tipping over due to external forces.

[0003] The patent specification with the publication number CN116816054B discloses an anti-dumping scaffold and construction method for bridge, road and building construction, the scaffold includes two supporting frames and a manned frame, the manned frame is fixedly mounted on the top end of the two supporting frames, a guardrail is fixedly mounted on the top end of the manned frame, three standing boards are arranged inside the manned frame, and a limit frame used in conjunction with the three standing boards is arranged inside the manned frame. The present invention is provided with an anti-dumping mechanism, which can not only adaptively adjust the center of gravity of the scaffold according to the combat position of the workers during the use of the scaffold, ensure the stability of the scaffold, and improve the safety of the use of the scaffold, but also eliminate the height difference between the standing boards during the use of the scaffold, and prevent the workers from being tripped by the height difference between the standing boards when moving on the scaffold.

[0004] This anti-dumping scaffolding was found to have some shortcomings during use. First, the design of its anti-dumping mechanism was not reasonable enough, and the anti-dumping effect needed to be improved. Second, the height of its guardrail and the height of the standing board could not be quickly adjusted according to actual needs. Third, its base could not take into account both the convenience of movement and the stability of support. Therefore, it needs to be optimized and improved. Summary of the invention
