Technical Field
[0001] This utility model relates to the field of corrugated steel web technology, specifically a corrugated steel web component for bridges. Background Technology
[0002] Corrugated steel webs are a new type of structural material primarily used in bridge and building structures. They replace traditional concrete or flat steel webs with corrugated steel plates, improving shear buckling resistance through the corrugated structure while significantly reducing material usage. Corrugated steel webs offer advantages such as reduced structural weight, improved structural performance, economic efficiency, environmental friendliness, and ease of construction. Compared to traditional concrete webs, they significantly reduce structural weight, avoid the cracking problems common in concrete webs, reduce concrete and steel usage, lower project costs, meet energy conservation and environmental protection requirements, and are easy to construct and maintain. Corrugated steel webs are widely used in bridge engineering, including continuous beam bridges, continuous rigid frame bridges, and cable-stayed bridges.
[0003] In bridge construction, existing corrugated steel sheets require multiple sheets to be spliced together to form a continuous long profile. The splicing is often done by hoisting, which makes it inconvenient to align the fixing holes during connection and fixing. The sheets themselves are heavy, and the swaying of the hoisting ropes during hoisting makes it difficult to align the sheets. Therefore, a corrugated steel web member for bridges is needed to meet people's needs. Utility Model Content
[0004] The purpose of this utility model is to provide a corrugated steel web member for bridges to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated steel web member for bridges, comprising a corrugated plate body and connecting corrugated plates; a centering guide structure is provided on one side of the corrugated plate body and on both sides of the connecting corrugated plates; a first base plate is fixedly installed on the side of the corrugated plate body away from the centering guide structure; and a fixing structure is provided on the centering guide structure. Preferably, the concentric guide structure includes a first concave arc plate, which is fixedly installed on the side of the corrugated plate body away from the first base plate. A second base plate is fixedly installed on the side connecting the corrugated plate, and a second convex arc plate is fixedly installed on the second base plate. A second concave arc plate is fixedly installed on the side of the corrugated plate away from the second convex arc plate.
[0006] Preferably, the first concave arc plate has a first arc groove, and the outer contour of the second convex arc plate is the same as the first arc groove.
[0007] Preferably, the outline dimensions of the first concave arc plate are the same as those of the second concave arc plate, and the outline dimensions of the first arc groove are the same as those of the second arc groove.
[0008] Preferably, there are two first concave arc-shaped plates, and the two first concave arc-shaped plates are respectively installed at the upper and lower ends of the corrugated plate body on the side away from the first base plate.
[0009] Preferably, there are two of each of the second substrate and the second convex arc plate, with the two second convex arc plates installed at the upper and lower ends of the side connecting the corrugated plate, and there are two second concave arc plates, with the two second concave arc plates installed at the upper and lower ends of the side connecting the corrugated plate away from the second convex arc plate.
[0010] Preferably, the fixing structure includes a first fixing ear, which is fixedly installed on the side of the corrugated plate body near the first concave arc plate. The first fixing ear is installed between two first concave arc plates. Second fixing ears are fixedly installed at both ends of the connecting corrugated plate. The second fixing ear on one side is fixedly installed between two second convex arc plates, and the second fixing ear on the other side is fixedly installed between two second concave arc plates.
[0011] Preferably, both the first fixing ear and the second fixing ear have a first fixing hole, a fixing bolt is installed in the first fixing hole, and fixing nuts are threaded on both ends of the fixing bolt.
[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) In this utility model, the board is divided into a corrugated board body and a connecting corrugated board. The corrugated board body is used for fixing at both ends, and the connecting corrugated board is used as a connecting component in the middle. During construction, the connecting corrugated board is lifted up, and the second convex arc plate side of the connecting corrugated board is brought close to the first concave arc plate side. When the connecting corrugated board is moved towards the corrugated board body side, it is only necessary to roughly align the second convex arc plate with the first arc groove on the first concave arc plate. Under the action of the arc surface of the first arc groove, the connecting corrugated board gradually moves closer to the corrugated board body and will automatically align. At this time, the second convex arc plate will automatically fit the arc of the first arc groove and complete the alignment, thereby facilitating the fixing of the board.
[0013] (2) When the center guide structure is aligned, the first fixing holes on the first fixing ear and the second fixing ear will also be aligned. At this time, the fixing bolt is inserted into the first fixing hole and the fixing nuts are tightened at both ends to fix the two plates. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a corrugated steel web member for bridges, including a corrugated plate body 1 and a connecting corrugated plate 4; in order to facilitate the alignment of the fixing holes of the two plates during hoisting, a centering guide structure 2 is provided on one side of the corrugated plate body 1 and both sides of the connecting corrugated plate 4; a first base plate 5 is fixedly installed on the side of the corrugated plate body 1 away from the centering guide structure 2; a fixing structure 3 is provided on the centering guide structure 2; the centering guide structure 2 facilitates alignment during hoisting. To achieve alignment, the centering guide structure 2 includes a first concave arc plate 20, which is fixedly installed on the side of the corrugated plate body 1 away from the first base plate 5. A second base plate 22 is fixedly installed on the side connecting the corrugated plate 4, and a second convex arc plate 23 is fixedly installed on the second base plate 22. A second concave arc plate 24 is fixedly installed on the side connecting the corrugated plate 4 away from the second convex arc plate 23. A first arc groove 21 is formed on the first concave arc plate 20, and the outer contour of the second convex arc plate 23 is the same as that of the first arc groove 21. The contour dimensions of the first concave arc plate 20 and the second concave arc plate 24 are the same. Similarly, the outline dimensions of the first arc groove 21 and the second arc groove 25 are the same. There are two first concave arc plates 20, which are respectively installed at the upper and lower ends of the corrugated plate body 1 on the side away from the first base plate 5. There are two second base plates 22 and two second convex arc plates 23, which are installed at the upper and lower ends of the side connecting the corrugated plate 4. There are two second concave arc plates 24, which are installed at the upper and lower ends of the side connecting the corrugated plate 4 on the side away from the second convex arc plate 23. During construction, the first arc plate 21 on one side of the corrugated plate body 1 is first... The base plate 5 is fixed to the bridge base. During splicing, the connecting corrugated plate 4 is hoisted using hoisting equipment. When moving the connecting corrugated plate 4 towards the corrugated plate body 1, the second convex arc plate 23 side of the connecting corrugated plate 4 is brought closer to the 120 side. Only the second convex arc plate 23 needs to be roughly aligned with the first arc groove 21 on the first concave arc plate 20. Under the action of the arc surface of the first arc groove 21, as the connecting corrugated plate 4 gradually moves closer to the corrugated plate body 1, it will automatically align. At this time, the second convex arc plate 23 will automatically conform to the curvature of the first arc groove 21, completing the alignment and facilitating the fixing of the plate. The same principle applies when fixing multiple connecting corrugated plates 4. The connecting corrugated plates 4 to be spliced are lifted up, and the second convex arc plate 23 of the connecting corrugated plate 4 to be spliced is aligned with the second arc groove 25 of the previous and fixed connecting corrugated plate 4. Using the same method, as the second convex arc plate 23 on the connecting corrugated plate 4 to be spliced gradually approaches the second concave arc plate 24 on the fixed connecting corrugated plate 4, under the guidance of the end face of the second arc groove 25, the protruding arc on the second convex arc plate 23 will automatically align with the second arc groove 25, thereby achieving the function of automatic circle alignment.
[0018] Example 2: As Figure 2To achieve the function of fixing the two plates, the fixing structure 3 includes a first fixing ear 30, which is fixedly installed on the side of the corrugated plate body 1 near the first concave arc plate 20. The first fixing ear 30 is installed between the two first concave arc plates 20. Second fixing ears 31 are fixedly installed at both ends of the connecting corrugated plate 4. One side of the second fixing ear 31 is fixedly installed between the two second convex arc plates 23, and the other side of the second fixing ear 31 is fixedly installed between the two second concave arc plates 24. First fixing holes 32 are opened on both the first fixing ear 30 and the second fixing ear 31, and fixing bolts are installed in the first fixing holes 32. 33. Fixing bolt 33 has fixing nuts 34 threaded on both ends. In order to fix the two plates, when the centering guide structure 2 is aligned, the first fixing holes 32 on the first fixing ear 30 and the second fixing ear 31 will also be aligned. At this time, the fixing bolt 33 is inserted into the first fixing hole 32, and the fixing nuts 34 are tightened at both ends to fix the two plates. It is worth noting that, considering certain processing errors, in order to facilitate the insertion of the fixing bolt 33 into the first fixing hole 32, the diameter of the first fixing hole 32 can be slightly larger than the diameter of the fixing bolt 33. The two adopt a clearance fit. The other features are the same as in embodiment 1.
[0019] The working principle is as follows: During construction, the first base plate 5 on one side of the corrugated plate body 1 is first fixed to the bridge foundation. During splicing, the connecting corrugated plate 4 is hoisted using hoisting equipment. The second convex arc plate 23 side of the connecting corrugated plate 4 is brought closer to the 120 side. When moving the connecting corrugated plate 4 towards the corrugated plate body 1, the second convex arc plate 23 only needs to be roughly aligned with the first arc groove 21 on the first concave arc plate 20. Under the action of the arc surface of the first arc groove 21, the connecting corrugated plate 4 gradually moves closer to the corrugated plate body 1 and automatically aligns. At this time, the second convex arc plate 23 will automatically fit the arc of the first arc groove 21, completing the alignment, thus facilitating the fixing of the plate. The same principle applies when fixing multiple connecting corrugated plates 4 in the future. The connecting corrugated plates 4 to be spliced are hoisted up, and the connecting corrugated plates 4 are then... When the second convex arc plate 23 of the connecting corrugated plate 4 to be spliced is aligned with the second arc groove 25 of the previous and fixed connecting corrugated plate 4, and using the same method as above, the second convex arc plate 23 on the connecting corrugated plate 4 to be spliced gradually moves closer to the second concave arc plate 24 on the fixed connecting corrugated plate 4, under the guidance of the end face of the second arc groove 25, the convex arc on the second convex arc plate 23 will automatically align with the second arc groove 25, thereby realizing the function of automatic circle alignment. In order to fix the two plates, when the centering guide structure 2 is aligned, the first fixing holes 32 on the first fixing ear 30 and the second fixing ear 31 will also be aligned. At this time, the fixing bolt 33 is inserted into the first fixing hole 32, and the fixing nuts 34 are tightened at both ends to fix the two plates.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
