[0030] [First Embodiment]

[0031] Reference Figure 1-4 The image shown is a prefabricated steel frame bridge structure disclosed in this embodiment, as follows: Figure 1 As shown, the bridge includes a bridge deck 1, the bottom of which is connected to a support column 2 via a combination device 4. Corresponding connecting devices 3 are provided on both sides of the bridge deck 1. By providing connecting devices and combination devices, the bridge deck and support columns can be quickly disassembled and recycled in the later stages, reducing material waste caused by building temporary bridges and improving the practicality and installation flexibility of the steel frame bridge.

[0032] like Figure 2-3As shown, the connecting device 3 in this embodiment includes a slot 31 on one side of the bridge plate 1. A perforated rod 34 is fixedly connected to the side of the bridge plate 1 away from the slot 31, and the slot 31 and the perforated rod 34 are correspondingly inserted and engaged. An extension plate 36 is fixed to the top of the side of the bridge plate 1 near the perforated rod 34, and a storage groove 35 is provided on the top of the side of the bridge plate 1 away from the extension plate 36. The extension plate 36 is inserted and engaged with the storage groove 35. By setting up the connecting device, the bridge plate 1 can be manually moved closer to another bridge plate 1, and the perforated rod 34 and the extension plate 36 can be moved synchronously by the bridge plate 1. When the perforated rod 34 moves to the position of being inserted into the slot 31 on the other bridge plate 1, the extension plate 36 is inserted into the storage groove 35 to fill the gap between the two bridge plates. This allows the inner wall of the perforated rod to be inserted and fitted with the inner wall of the slot. Thus, different numbers of bridge plates can be used to splice bridges of different lengths, improving the applicability range. At the same time, the bridge plates can be quickly disassembled and recycled later, further reducing costs.

[0033] To further improve the connection stability between adjacent bridge plates 1, a circular groove 39 is provided on one side of the bridge plate 1. A threaded hole 32 is provided on the bridge plate 1 corresponding to the circular groove 39. The threaded hole 32 is connected to the slot 31. An installation groove is provided inside the multi-hole rod 34 corresponding to the threaded hole 32. The bolt 33 passes through the circular groove 39 and the threaded hole 32 in sequence and enters the installation groove. By rotating the bolt 33 with a tool, the bolt 33 is rotated into the threaded hole and the position inside the multi-hole rod to fix the position of the multi-hole rod, so as to complete the rapid assembly of the two bridge plates. The inner diameter of the circular groove 39 is matched with the outer diameter of the nut of the bolt 33 to effectively limit the axial insertion position of the bolt 33.

[0034] A filling plate 37 is fixed to the top of the extension plate 36. A first rectangular groove 38 is provided on the top of the side of the bridge plate 1 away from the extension plate 36. The filling plate 37 can be inserted into the interior of the first rectangular groove 38 and engage with it. By setting the filling plate, the filling plate can enter the interior of the first rectangular groove to fill the height difference between the extension plate and the bridge plate, thereby improving the smoothness of the bridge surface at the top of the bridge plate 1 and improving the walking stability and safety factor.

[0035] To further improve the connection strength, a reinforcing block 313 is fixedly connected to the bottom of the extension plate 36. The reinforcing block 313 is fixedly connected to the bridge plate 1. A second rectangular groove 311 is provided on the side of the bridge plate 1 away from the extension plate 36. The second rectangular groove 311 is adapted to the reinforcing block 313. By setting the reinforcing block, the reinforcing block can provide auxiliary support for the extension plate and improve the connection strength between the extension plate and the bridge plate. As a preferred embodiment, the cross section of the reinforcing block 313 in this embodiment is set as a triangle, and the cross section of the second rectangular groove 311 is set as a rectangle adapted to the reinforcing block 313. Those skilled in the art can also set the cross section of the reinforcing block 313 and the cross section of the second rectangular groove 311 to other mutually matching shapes according to actual needs.

[0036] A limiting block 312 is fixedly connected to the inner side of the multi-hole rod 34, and a limiting groove 310 is opened on the inner side of the slot 31. The limiting block 312 can be inserted into the limiting groove 310 and engage with it. By setting the limiting block and the limiting groove, the limiting block can be located inside the limiting groove to assist in limiting the multi-hole rod, reducing the situation where the multi-hole rod shakes unexpectedly inside the slot.

[0037] like Figure 3-4 As shown, the combined device 4 in this embodiment includes a rectangular frame 41 fixed to the bottom of the bridge plate 1. A first through hole 42 is provided inside the rectangular frame 41, and a second through hole 44 is provided on the top of the support column 2. The first through hole 42 and the second through hole 44 are positioned correspondingly, and a screw 45 is threaded through them. One end of the screw 45 is fixedly connected to a connecting plate 47, and the outer edge of the other end of the screw 45 is threaded with a nut 46. The outer edges of the connecting plate 47 and the nut 46 are larger than the inner diameter of the first through hole 42. By setting up the combined device, the bridge plate can be moved. 1. This causes the bridge plate to move synchronously with the rectangular frame 41. When the rectangular frame 41 moves to the point where it fits onto the surface of the support column 2, the first through hole and the second through hole coincide. At this time, the moving connecting plate 47 drives the screw 45 to move synchronously. When the screw 45 moves to the position where it is fully inserted and passes through the first and second through holes, the nut 46 is rotated at the outer edge of the other end of the screw 45 until the nut 46 moves axially to the position where it abuts the surface of the rectangular frame. The screw then connects the rectangular frame to the support column, thereby achieving a rapid combination effect between the support column and the bridge plate.

[0038] As a further preferred embodiment, a handle 48 is fixedly connected to one side of the connecting plate 47. The inner side of the handle 48 has multiple anti-slip protrusions. By providing the handle, users can easily move the connecting plate and screw manually, improving the ease of operating the screw. A support plate 43 is fixedly connected to one side of the rectangular frame 41. The support plate 43 is fixedly connected to the bottom of the bridge plate 1. By providing the support plate, the support plate can increase the support range of the rectangular frame on the bridge plate, improving the stability of the bridge plate, and also increasing the connection strength between the rectangular frame and the bridge plate.

[0039] The specific working process of this embodiment is as follows:

[0040] First, move the bridge plate 1, causing the bridge plate 1 to move the rectangular frame 41. When the rectangular frame 41 moves to the position where it is fitted onto the surface of the support column 2, the first through hole 42 and the second through hole 44 coincide. At this time, move the connecting plate 47, causing the connecting plate 47 to move the screw 45. When the screw 45 moves to the position where it is fully inserted and passes through the first through hole 42 and the second through hole 44, rotate the nut 46, causing the nut 46 to move axially along the screw 45. When the nut 46 moves to the position where it abuts the surface of the rectangular frame 41, the rectangular frame 41 is connected and fixed to the support column 2 through the screw 45, thereby achieving the effect of rapid assembly of the support column 2 and the bridge plate 1.

[0041] Then, move the bridge plate 1, causing the perforated rod 34 and the extension plate 36 to move synchronously. When the perforated rod 34 moves to the position of inserting into the slot 31 on the bridge plate 1 connected to the support 2, the extension plate 36 inserts into the receiving slot 35 to fill the gap between the two bridge plates 1, so that the inner wall of the perforated rod 34 fits against the inner wall of the slot 31. Then, by rotating the bolt 33, the bolt 33 is turned into the threaded hole 32 and the position of the perforated rod 34 to fix the position of the perforated rod 34, thus completing the rapid assembly of the two bridge plates 1. This allows the connection spacing between the two bridge plates 1 to be adjusted, and the rapid assembly of the temporary steel frame bridge is completed.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may use the disclosed technical content to make changes or modifications to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the utility model's technical solution, still fall within the protection scope of this utility model's technical solution. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.
