Description

Technical Field

[0001] The utility model relates to the technical field of steel structure auxiliary construction, in particular to a telescopic and detachable formwork-free floor slab cantilevered part supporting component. Background Art

[0002] With the continuous development of prefabricated building technology, the formwork-free floor system, as an innovative structural system, has been widely used in construction projects for its advantages of simple construction, material conservation, environmental protection and high efficiency. The system uses corrugated steel plates, steel truss floor decking and other materials as the floor bottom formwork. After pouring, there is no need to remove the bottom formwork, and it directly becomes part of the structure, which greatly simplifies the construction process. Existing, when pouring the cantilevered part of the formwork-free floor, it needs to be supported from the bottom. Traditional support methods include setting up scaffolding or using fixed welded cantilever rods for support. These methods are not only inefficient and labor-intensive, but also the welded cantilever rod support structure cannot be adjusted or disassembled, resulting in material waste and usage limitations.
