Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an anti-leakage structure at a connection of a steel-concrete structure. Background Art
[0002] Roof waterproofing is a key and challenging aspect of building waterproofing. In concrete structures, all structural components are cast together on-site, creating no gaps or cracks, and thus preventing leakage. However, where vertical steel components protrude from the roof, such as in elevators and stairwells, a structural gap exists between the floor decking and the vertical steel components, creating a significant risk of leakage and potentially creating hidden dangers. Summary of the Invention
[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide an anti-leakage structure for the connection of steel-concrete structures, which has a simple structure and is convenient and quick to construct. It can effectively prevent leakage through multiple lines of defense and can be widely used in the anti-leakage node structure of the vertical steel structure components at the roof of prefabricated steel structure buildings.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0005] A leakage-proof structure at the connection of a steel-concrete structure includes a steel pipe column, concrete in the column, a steel beam, a floor decking plate, a truss steel bar, a floor surface layer and a roof building surface layer. The steel beam is fixedly installed on the circumference of the steel pipe column, the floor decking plate is fixedly installed on the steel beam, the truss steel bar is placed on the floor decking plate, concrete is poured on the truss steel bar to form a floor surface layer, and a roof building surface layer is arranged above the floor surface layer; it also includes a roof concrete flange and a waterstop steel plate; the roof concrete flange is arranged around the circumference of the steel pipe column, the roof concrete flange is located above the floor surface layer and the upper end of the roof concrete flange is higher than the roof building surface layer; the waterstop steel plate is located in the roof concrete flange, and the waterstop steel plate is welded to the steel pipe column and the truss steel bar.
[0006] Wherein, the waterstop steel plate includes a horizontal waterstop steel plate and a vertical waterstop steel plate which are vertically arranged, and the horizontal waterstop steel plate and the vertical waterstop steel plate are welded to each other.
[0007] Wherein, the gap between the horizontal water-stop steel plate and the vertical water-stop steel plate is fully welded and sealed.
[0008] Wherein, the roof concrete flange is fitted with the steel pipe column.
[0009] Wherein, support angle steels are fixed between adjacent steel beams, and the floor deck is located above the support angle steels.
[0010] In summary, the anti-leakage structure at the connection of this type of steel-concrete structure has a simple structure and is convenient and quick to construct. It can effectively prevent leakage through multiple lines of defense and can be widely used in the anti-leakage node structure of the vertical steel structure components at the roof of prefabricated steel structure buildings.
[0011] The roof is covered with concrete and water-stop steel plates, forming a multi-layer waterproofing structure. This effectively seals the gaps between the floor slab and the vertical steel structure components, effectively preventing water leakage and improving construction efficiency and reducing construction costs. Furthermore, this method is simple to operate and easy to master, making it highly valuable for widespread application. BRIEF DESCRIPTION OF THE DRAWINGS
