Description

Technical Field

[0001] The utility model relates to the technical field of corrugated steel webs, and specifically relates to a composite corrugated steel web. Background Art

[0002] The corrugated steel web composite ribbed beam is a bridge structure form with a specific structure and construction technology. The corrugated steel web composite ribbed beam mainly consists of a lower flange plate, an upper flange plate, and a corrugated steel web supported between the two. The lower flange plate is provided with a prestressing system, including a middle prestressing structure and two side prestressing structures. The corrugated steel web has a strong shear resistance function, which can effectively improve the overall stability and reliability of the bridge structure. At the same time, its corrugated design also has a certain corrugation effect, which can reduce the sensitivity to geometric initial defects and improve the prestressing efficiency. The corrugated steel web has a strong shear resistance function, which can effectively improve the overall stability and reliability of the bridge structure. At the same time, its corrugated design also has a certain corrugation effect, which can reduce the sensitivity to geometric initial defects and improve the prestressing efficiency. The corrugated steel web composite ribbed beam has been widely used in China, involving the bridge construction in many provinces and cities. Its application scope includes various bridge structure styles such as simply supported beam bridges, continuous rigid frame bridges, continuous bridges, and cable-stayed bridges. The cross-section of the box girder can select different box chamber combination forms, and can increase the span of the corrugated steel web, with a maximum of up to 200 meters.

[0003] Chinese Utility Model Patent CN219218647U discloses an assembled corrugated steel web continuous composite beam, which includes concrete slabs arranged up and down. A plurality of symmetrically arranged corrugated webs are arranged between the concrete slabs. The corrugated webs are divided into upper webs and lower webs according to the structure. Among them: a plurality of docking holes are opened on both the upper web and the lower web, and studs are inserted and fitted in the docking holes. A plurality of positioning columns are fixedly installed on the corrugated web, and docking heads are fixedly installed on the positioning columns. The assembled corrugated steel web continuous composite beam provided by the utility model can fix the upper web and the lower web by adjusting the distance between the upper web and the lower web and cooperating with the studs, so as to adjust the size of the corrugated web to adapt to the bow-shaped composite beam; at the same time, the adjusted corrugated web cooperates with the triangular frame formed by the cross-arranged diagonal bars, which can provide additional buffer support force for the composite beam, thereby increasing the stability of the composite beam.

[0004] However, although the above corrugated steel web composite beam can provide additional buffer support force for the composite beam, thereby increasing the stability of the composite beam, it does not have the locking function of the studs. If the studs become loose, it will affect the firmness of the connection between the upper web and the lower web, thereby affecting the construction safety, having a certain potential safety hazard, and being inconvenient for users to use.
