Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to a temporary supporting structure for corrugated steel plate floor construction. Background Art

[0002] Corrugated steel floor is a common form of building structure. It uses corrugated thin steel plates with concave and convex shapes as lining plates and cast-in-place concrete to support the steel beams to form an integral floor. It is mainly composed of three parts: floor layer, composite plate and steel beam. It is suitable for large space buildings and high-rise buildings. Corrugated steel floor has excellent earthquake resistance, wind resistance, strong bearing capacity and other characteristics. It is widely used in industrial buildings, commercial buildings and residential buildings. In the construction process of corrugated steel floor, temporary support is the key link to ensure structural stability and construction safety. The traditional temporary support method for corrugated steel floor construction mainly adopts steel pipe support or steel pallet support. These methods require a large amount of steel and welding technology, have a long project cycle, and are difficult to construct.
