Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building construction, in particular to the outdoor ceiling construction of steel structure, and specifically relates to a steel structure corridor outdoor high-altitude reverse-hung aluminum plate assembly type ceiling system. BACKGROUND

[0002] With the progress of science and technology and the improvement of people's aesthetic, the construction industry has also undergone great changes, and more and more projects are pursuing architectural modeling art and green construction.

[0003] Steel structure is not only a green building material, but also can realize large-span construction, so it has been widely used in various green projects and large-span structure projects. For example, steel structure corridors are often constructed between high-rise buildings now. Such steel structure corridor structure is not only green and environmentally friendly, but also increases the aesthetic of the building structure, and also increases the practicality of the building structure, the variability of form and function, and gives the building structure more possibilities.

[0004] In order to further improve the aesthetic and green environmental protection properties of the steel structure corridor between two high-rise buildings, the construction unit plans to install an aluminum plate ceiling at the bottom of the steel structure corridor. The aluminum plate ceiling is not only light in weight and high in strength, but also a green and environmentally friendly material. However, in the specific construction process, due to the high height, large span and no installation force point of the steel structure corridor, the installation difficulty of the aluminum plate ceiling is greatly increased. Another problem is how to ensure the neatness of the aluminum plate ceiling installed on the steel structure corridor. Due to its high height and large span, the adjustment of the neatness of the ceiling is difficult, so a special hoisting device needs to be designed to solve it.

[0005] In summary, the aluminum plate ceiling installation design of the steel structure corridor indeed increases the aesthetic of the building structure, and is green, environmentally friendly, energy-saving and emission-reducing, but the project indeed brings serious technical challenges to the construction of the construction unit.

A clamping plate is welded and fixed between the lower ends of the two C-type clamps, and four round bolt holes are punched on the clamping plate. The gap between the two C-type clamps and the punched hole on the outer top surface plate are the positions through which the upper section of the adjusting rod passes. The left and right horizontal clamps have the same structure, mainly consisting of two parallel, spaced-apart straight clamps. One end of each straight clamp is welded and fixed to the lower part of the hanging plate. The top surfaces of the two straight clamps are welded together by a top plate, and the bottom surfaces are welded together by a bottom plate with a punched hole in the middle. The gap between the two straight clamps and the punched hole on the bottom plate are the positions through which the lower section of the adjusting rod passes.

5. The outdoor high-altitude inverted aluminum panel prefabricated ceiling system for steel structure corridors according to claim 4, characterized in that: A stiffening plate is provided between the clamping plate between the lower ends of the two C-type cards and the bottom gusset plate between the bottom surfaces of the two C-type cards.

6. The prefabricated suspended ceiling system for outdoor high-altitude steel structure corridors according to claim 4, characterized in that: The C-type card is made of 12# channel steel; the top, side and bottom gusset plates are all made of 8mm thick steel plates with a size of 60*80mm.

7. The outdoor high-altitude inverted aluminum panel prefabricated ceiling system for steel structure corridors according to claim 4, characterized in that: The hanging plate is made of a steel plate that is 950mm long, 200mm wide and 8mm thick, with four long bolt holes punched on its upper part. The positions of the four long bolt holes correspond to the four round bolt holes on the clamp plate.

8. The outdoor high-altitude inverted aluminum panel prefabricated ceiling system for steel structure corridors according to claim 4, characterized in that: The straight card is made of 12# channel steel, and the top and bottom gusset plates are made of 8mm thick steel plates with a size of 60*80mm.

9. The prefabricated suspended ceiling system for outdoor high-altitude steel structure corridors according to claim 4, characterized in that: Both the left and right adjusting rods use 14mm adjusting screws and are 1100mm long.
