Description

Technical Field

[0001] This utility model relates to the field of municipal pipeline engineering technology, specifically to a composite corrugated steel temporary bridge structure. Background Technology

[0002] In some municipal pipeline projects, excavation of urban roads is required for pipeline laying or replacement. To ensure normal traffic flow during construction, temporary bridges are typically erected over the trenches. A standard temporary bridge consists of a foundation, main beams, secondary beams, and a steel deck for vehicles. The complexity of the temporary bridge structure means that its assembly and dismantling consume considerable construction time, significantly impacting the construction period and project cost.

[0003] In the municipal engineering sector, long-span steel temporary bridges are typically Bailey bridges, which are temporary bridges assembled from Bailey beams. Shorter-span steel temporary bridges use I-beams as the main load-bearing structure, with steel plates fully laid on top of the I-beams to meet passage requirements. Currently, the application of long-span steel temporary bridges is relatively mature, with high acceptance in terms of construction speed and project cost. In the application of short-span steel temporary bridges, due to the complexity of the temporary bridge structure, there is still room for optimization in terms of construction period and cost.

[0004] Therefore, this utility model is proposed. Utility Model Content

[0007] In an optional embodiment, multiple sets of the force-transmitting webs are attached to the roadway steel plate and the arc-shaped corrugated steel plate.

[0008] In an optional embodiment, each set of force-transmitting webs is symmetrically arranged about a symmetrical cross-section passing through the top of the arc-shaped corrugated steel plate.

[0009] In an optional embodiment, one end of the force-transmitting web is connected to the roadway steel plate, and the other end of the force-transmitting web is connected to the top of the corrugated portion of the arc-shaped corrugated steel plate.

[0010] In an optional embodiment, a pre-drilled hole is provided in the roadway steel plate or the force transmission web for filling welding of the roadway steel plate or the force transmission web.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it may be directly or indirectly located on that other component. When a component is referred to as "connected to" another component, it may be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate orientations or positions based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution.

[0021] Please see the appendix Figure 1-4 The purpose of this embodiment is to provide: 1. A composite corrugated steel temporary bridge structure, characterized in that it includes: an arc-shaped corrugated steel plate 4, one end of which is connected to a first support steel plate 7, the other end of which is connected to a second support steel plate 6, and the top end of which is connected to a roadway steel plate 1; a first end steel plate 2 is connected between one end of the roadway steel plate 1 and the first support steel plate 7, and a second end steel plate 3 is connected between the other end of the roadway steel plate 1 and the second support steel plate 6; multiple sets of force-transmitting webs 5 are provided between the arc-shaped corrugated steel plate 4 and the roadway steel plate 1. The first support steel plate 7 and the second support steel plate 6 overlap on a large trench or a small foundation pit, and the roadway steel plate 1 is flush with the surface of the road structure.

[0022] Specifically, multiple sets of force-transmitting webs 5 are attached to the roadway steel plate 1 and the arc-shaped corrugated steel plate 4. Each set of force-transmitting webs 5 is symmetrically arranged about the symmetrical section passing through the top of the arc-shaped corrugated steel plate 4.

[0023] In this embodiment, one end of the force-transmitting web 5 is connected to the roadway steel plate 1, and the other end of the force-transmitting web 5 is connected to the top of the corrugated portion of the arc-shaped corrugated steel plate 4. Pre-drilled holes are provided on the roadway steel plate 1 or the force-transmitting web 5 for filling and welding.

[0024] This utility model uses an arc-shaped corrugated steel plate 4 as a temporary bridge. The temporary bridge consists of a roadway steel plate 1 of a certain thickness and an arc-shaped corrugated steel plate 4. The wave pitch and wave height of the arc-shaped corrugated steel plate 4 can be adjusted according to the different spans of the temporary bridge (e.g., 6 meters, 8 meters, 10 meters, 12 meters) to meet the load-bearing requirements. The width of the arc-shaped corrugated steel plate 4 is determined by its own weight and ease of hoisting. The advantages of the arc-shaped corrugated steel plate 4 are its large section modulus, high stiffness, and ability to be prefabricated in a factory for reuse. Using arc-shaped corrugated steel plate 4 to construct the temporary bridge results in good overall integrity, quick and convenient installation and dismantling, and no adverse impact on the surrounding environment during construction, making it an environmentally friendly construction measure. In particular, the high stiffness of the arc-shaped corrugated steel plate 4 can effectively reduce the height of the temporary bridge, thereby increasing the working space within the trench.
