Description

A support tool for post-cast belt or slab back-up

technical field

The utility model relates to the technical field of building construction auxiliary equipment, in particular to a support tool for post-cast belt or floor slab back-to-top.

Background technique

The existing basement subsidence poured belt support system generally uses steel pipe scaffolding for support. When installing or dismantling the steel pipe scaffolding, a large number of screws and steel pipes need to be processed one by one. A lot of time not only requires a large labor cost, but also increases the labor intensity of the workers and delays the progress of the project. At the same time, the independent support frame of the post-cast belt needs to be kept until the main building structure is capped. The occupation period is long, and a large number of support frames are used as supports. The construction unit needs to pay a large rental fee, and the cost is relatively large. And the length of the support structure is not easy to adjust. In addition, the post-cast belt formwork support system can only be dismantled after 28 days of post-cast concrete curing. The dismantling is done in order from top to bottom, which takes a long time, wastes manpower and material costs, and is difficult in daily management, and the support materials are easily damaged. Formwork, bottom support, top support and other materials are easily deformed and corroded, resulting in loosening of the formwork support system of the post-casting tape.

Therefore, it is of great practical significance to develop a support tool for post-casting belts with simple structure, convenient operation, good adaptability and high operating efficiency.
