Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular, it is a temporary support structure for the construction of profiled steel sheet floors with adjustable height. Background Technology

[0002] Corrugated steel sheet floors, as a widely used building structure, are commonly found in industrial, commercial, and residential buildings due to their excellent earthquake and wind resistance and high load-bearing capacity. During the construction of such floors, temporary support systems are crucial for ensuring structural stability and construction safety. Traditional methods primarily rely on erecting steel pipe scaffolding or welding prefabricated steel support plates, requiring the installation of corresponding steel pipe scaffolding or the customization of different sized support plates for steel beams of varying dimensions. This approach not only consumes a large amount of steel and involves extensive welding work, resulting in significant turnover losses, but also extends the construction period and increases construction difficulty.

[0003] Therefore, developing a relatively simple, efficient, and adaptable temporary support structure for profiled steel sheet floors has become an urgent issue for those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary support structure for the construction of profiled steel sheet floors with adjustable height, in order to solve the technical problems of traditional temporary support systems that consume a lot of steel and welding work, have significant turnover losses, and also lead to extended construction period and increased construction difficulty.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] An adjustable-height temporary support structure for profiled steel sheet floor construction includes a vertical support, a horizontal steel pipe beam, and a supporting steel pipe. The vertical support is positioned between the upper and lower flanges of the steel structure beam, with its upper end resting on the bottom of the upper flange of the steel structure beam, and a gap remaining between its lower end and the lower flange of the steel structure beam. The vertical support is a tubular structure, with a first adjusting nut connected to its bottom. A downward vertical support is positioned below the first adjusting nut, with its bottom resting on the lower flange of the steel structure beam. On the edge plate, the top of the downward vertical support is inserted into the interior of the upward vertical support; the upper part of the downward vertical support is threadedly connected to the first adjusting nut; the horizontal beam steel pipe is horizontally arranged below the profiled steel sheet floor slab, one end of the horizontal beam steel pipe is connected to the upper part of the upward vertical support, and a supporting steel pipe is provided on the side of the horizontal beam steel pipe away from the upward vertical support; a second adjusting nut is provided at the top of the supporting steel pipe, and a bottom support is provided inside the supporting steel pipe; the upper end of the bottom support extends beyond the top of the supporting steel pipe and is threadedly connected to the second adjusting nut; a support plate is provided at the top of the bottom support;

[0007] An adjustable diagonal brace is provided between the bottom of the supporting steel pipe and the lower part of the vertical support; the length of the adjustable diagonal brace is adjustable, and both ends of the adjustable diagonal brace are detachably connected to the supporting steel pipe and the vertical support respectively.

[0008] Preferably, the outer surface of the vertical support is provided with threads, and a bottom support plate is provided at the lower end of the vertical support.

[0009] Preferably, the vertical support and the crossbeam steel pipe are connected by welding; the crossbeam steel pipe and the support steel pipe are connected by welding.

[0010] Preferably, the adjustable diagonal brace includes a lower diagonal brace steel pipe and an upper diagonal brace screw; a third adjusting nut is provided at the top of the lower diagonal brace steel pipe; the upper diagonal brace screw is inserted into the long part of the lower diagonal brace steel pipe, and the upper diagonal brace screw and the third adjusting nut are threadedly connected; the total length of the lower diagonal brace steel pipe and the upper diagonal brace screw can be adjusted by rotating the upper diagonal brace screw.

[0011] Preferably, the vertical support and the lower diagonal brace steel pipe are connected by a first bolt; the upper diagonal brace screw and the crossbeam steel pipe are connected by a second bolt.

[0012] Preferably, the pallet is made of channel steel; the upper end of the bottom support is inserted into the groove of the channel steel and welded to the pallet.

[0013] Compared with the prior art, the present invention has the following features and beneficial effects.

[0014] 1. The temporary support structure constructed by this utility model has a flexible and adjustable height, making it highly adaptable. By adjusting three adjusting nuts, the height of the vertical support and the height of the bottom support can be precisely adjusted to accurately match the web height of the steel structure beam, thereby lifting and supporting the profiled steel sheet bottom mold at different heights and ensuring the flatness of the floor slab bottom surface. The temporary support structure of this utility model is an adjustable rigid component that is directly and firmly pressed between the upper and lower flange plates of the steel structure beam to form the main load-bearing structure. The channel steel at the top of the bottom support can connect adjacent independent support units laterally into a whole, effectively improving the collaborative working ability and overall stability of the entire temporary support system and resisting local loads or deformations.
