Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a weightless suspended basket structure based on a double-layer pergola beam. Background Technology

[0002] When a pergola beam structure is installed on the roof, steel pipe and coupler scaffolding is generally used for suspended platform installation. This method has certain safety risks, such as the possibility of the entire structure collapsing if the scaffolding is not erected securely. The roof bears the load of the scaffolding, the suspended platform, and the counterweight load, which may damage the waterproof layer or the floor structure. The scaffolding erection period is long, and the flexibility of construction is poor, which affects the construction efficiency. In addition, the scope of application is limited. For example, it is difficult to erect scaffolding on pitched roofs, irregular roofs, and light wells. Vulnerable roofs such as glass curtain walls and skylights cannot directly support the scaffolding.

[0003] Therefore, there is an urgent need for a suspended platform structure suitable for inclined and straight truss beams, which can enable construction operations on the exterior facade of buildings.

It can also reduce the risk of having to bear the load of scaffolding, suspended platform and counterweight when installing the suspended platform on the roof. It is not necessary to use the method of laying steel beams and backfilling to reinforce the roof according to the roof bearing capacity. (2) Since the suspended platform is directly anchored to the pergola beam, it has better wind resistance and can reduce the risk of swaying caused by wind. (3) Multiple third connecting sleeves 455 are provided. Through multi-point anchoring, the suspended platform structure can bear a larger load. (4) When the upper steel beam 1 is tilted, the bottom of the front support leg of the suspended platform is provided with angle steel 315 welded to the upper steel beam 1, which can prevent the front support leg of the suspended platform from sliding down the upper steel beam 1 under the action of gravity, and can be applied to tilted roofs.
