Description

Technical Field

[0001] The invention relates to the technical field of building formwork construction, and in particular to a lifting type beam and slab formwork supporting structure and an operating method thereof. Background Art

[0002] When pouring concrete beams and slabs of building structures, it is necessary to set up a support frame and set up a formwork on it to complete the pouring operation. In order to ensure the quality of beam and slab pouring and the safety of the construction process, the formwork support should have a certain strength, rigidity and stability to withstand the load during the construction process. The existing formwork support frame is usually made of steel pipes, which are composed of horizontal, vertical and oblique steel pipes to form a formwork bracket, and the main beam, secondary beam and panel are set up on it to support the pouring and forming of concrete.

[0003] The steel pipe support frame is generally a full-frame support, which occupies all the space under the cast beams and slabs. During the erection of the support, personnel cannot pass through the erection area, which also restricts the transportation and movement of materials and other supplies; the steel pipe support frame is erected and dismantled manually, which consumes a lot of manpower and time, and the high-altitude support is more dangerous. When the casting height of the building structure beams and slabs is high, the full-frame support is erected from the bottom to the designed height, the self-weight of the steel pipe support increases, the load increases, and its overall stability and bearing capacity decrease accordingly. Therefore, the steel pipe support frame cannot meet the higher support height. Summary of the invention
