Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to an overhead cantilever support formwork platform. Background Technique

[0002] During the construction of the main structure such as office buildings and schools, there are often situations where the main structure of the cantilever roof needs to be constructed. When constructing at the cantilever roof structure, a full hall support formwork frame is generally erected from the ground.

[0003] The following problems exist when erecting a full hall support formwork frame:

[0004] Firstly, the height-width ratio of the ultra-high support formwork frame exceeds the limit, and the wind load is large. Therefore, a large number of connecting wall members need to be added to resist overturning, and the width of the full hall support formwork frame also needs to be increased to meet the height-width ratio requirements;

[0005] Secondly, the engineering quantity of the full hall support formwork frame is large, the self-weight is heavy, and the requirements for the bearing capacity and settlement of the foundation are high. Generally, the foundation also needs to be tamped and hardened;

[0006] Thirdly, when erecting a full hall support formwork frame on backfill soil, it is easy to settle, resulting in downward deflection under the cantilever roof, increasing the quality and safety risks;

[0007] Fourthly, since it is difficult to install a cantilever unloading platform in the area below the cantilever roof structure, the later removal and hoisting of the full hall support formwork frame are difficult, the transfer engineering quantity of the formwork frame materials is large, the construction is difficult, the cost is high, and the safety risks are increased. Content of the Utility Model

[0008] In view of this, the utility model provides an overhead cantilever support formwork platform, which can simplify the installation and disassembly process and reduce the installation and disassembly difficulty; greatly reduce the erection workload and reduce the construction cost.

[0054] The embodiment provides a high-altitude cantilever support formwork platform, in which the cantilever I-beam 1, the diagonal I-beam 2 and the vertical I-beam 3 form a stable triangular system, which can be erected using two adjacent layers of structural beams and slabs.
