Description

Technical Field

[0001] The utility model relates to the technical field related to construction, and more specifically to a formwork frame for high-altitude large cantilevered components near the sea. Background Art

[0002] With the increase of super high-rise buildings in the construction market, landmark buildings are increasingly favored by urban development. Often, through the creative design of architectural shapes, buildings become the image spirit and landmark of a certain area, resulting in many large cantilever components, and most of the cantilever lengths are greater than 5m. For on-site construction, structural safety and quality are crucial during the pouring process. There are two existing technologies:

[0003] One is to use ground-type scaffolding for support, and set up scaffolding from the ground to the cantilever structure floor. The foundation needs to be hardened, and the scaffolding is reinforced with anchor points at each floor to ensure the safety and quality of cantilever structure construction; the other is ordinary I-beam cantilever, and cantilever I-beams need to be set up from at least 2 floors below the cantilever structure to share the load and provide an operating surface to ensure construction quality and safety.

[0004] Although the above two methods can provide certain guarantees for construction safety and quality, during the construction process, a large amount of materials are used, the stability of the internal frame is poor, and there are major safety and quality risks. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model aims to provide a formwork support frame for large cantilevered components at high altitude near the sea.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0009] As a further description of the above technical solution: a safety wire rope is fixedly connected to a cantilever beam above the cantilever beam connected to the I-beam cantilever beam main beam, and the other end of the safety wire rope is connected to the I-beam cantilever beam main beam.

[0010] As a further description of the above technical solution: the lower support rod is a 22a I-beam with left and right openings, and the stiffening rib is a 10# channel steel.
