[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] See Figure 1 and Figure 2This utility model discloses a Bailey bridge sheet connecting device, including a first connecting rod 1, a second connecting rod 2, and a connector 3 located at the same end of the first connecting rod 1 and the second connecting rod 2. The first connecting rod 1 and the second connecting rod 2 are preferably channel steels, arranged parallel to each other and connected side-by-side. One end of the connector 3 is connected between the first connecting rod 1 and the second connecting rod 2, i.e., the connector 3 is sandwiched between the first connecting rod 1 and the second connecting rod 2. The connector 3 is a male connector for connecting another Bailey bridge sheet connecting device. To connect the first connecting rod 1 and the second connecting rod 2, a connecting block 4 is also provided between them. The connecting block 4 is welded between the first connecting rod 1 and the second connecting rod 2, forming a whole. For ease of positioning and welding, positioning structures 41 are provided on both sides of the connecting block 4, and the positioning structures 41 on both sides of the connecting block 4 are respectively connected to the first connecting rod 1 and the second connecting rod 2. Before welding, the positioning structure 41 is first connected to the first connecting rod 1 and the second connecting rod 2 to form a pre-position, and then welding is performed. This can reduce the probability of the connecting block 4 shifting and improve welding accuracy and quality.

[0021] The beneficial effects of this utility model embodiment are as follows:

[0022] This utility model embodiment of the Bailey panel connecting device includes a first connecting rod 1, a second connecting rod 2, and a connecting block 4. When the connecting block 4 is welded to the first connecting rod 1 and the second connecting rod 2, positioning structures 41 are provided on both sides of the connecting block 4. Using the positioning structures 41, the connecting block 4 can be pre-positioned between the first connecting rod 1 and the second connecting rod 2, thereby achieving a pre-positioning effect. The overall volume of the connecting block 4 is larger than that of existing connecting pieces, which is beneficial for welding and can also avoid displacement through pre-positioning, thereby ensuring the quality of welding and improving the overall strength and quality of the Bailey panel connecting frame.

[0023] The connecting block 4 includes a first folded edge 42 and a second folded edge 43, which are arranged in parallel. During pre-positioning, after the positioning structure 41 is connected, the first folded edge 42 is flush with the upper surfaces of the first connecting rod 1 and the second connecting rod 2, and the second folded edge 43 is flush with the lower surfaces of the first connecting rod 1 and the second connecting rod 2. By controlling the flushing effect of the upper and lower surfaces, the positioning quality can be controlled, and the first folded edge 42 and the second folded edge 43 can be prevented from shifting, thereby ensuring the welding quality. The same side of the first folded edge 42 and the second folded edge 43 abuts against the first connecting rod 1, and the other side of the first folded edge 42 and the second folded edge 43 abuts against the second connecting rod 2 to achieve the positioning effect.

[0024] Furthermore, the connecting block 4 also includes a middle folded edge 44, which is vertically arranged. The first folded edge 42 and the second folded edge 43 are respectively located at the upper and lower ends of the middle folded edge 44. One side of the middle folded edge 44 abuts against the first connecting rod 1, and the other side abuts against the second connecting rod 2. The middle folded edge 44 not only improves the connection strength between the first folded edge 42 and the second folded edge 43, but also connects the first folded edge 42 and the second folded edge 43 into a whole. This facilitates the placement of the connecting block 4 as a whole between the first connecting rod 1 and the second connecting rod 2, saving placement steps and facilitating overall pre-positioning, thus improving the positioning effect. Moreover, compared with a single connecting piece, the connecting block 4 has a larger volume, which is beneficial for installation and welding, and it is not easy to shift after pre-positioning.

[0025] The provision of the intermediate folded edge 44 also facilitates the provision of the positioning structure 41. The first folded edge 42 and the second folded edge 43 are located at the upper and lower parts of the first connecting rod 1 and the second connecting rod 2. The first connecting rod 1 and the second connecting rod 2 are channel steels with flanges at their upper and lower parts. It is not easy to provide positioning holes 412 on the flanges. However, with the provision of the intermediate folded edge 44, the positioning structure 41 is provided on the intermediate folded edge 44. The positioning structure 41 includes positioning posts 411 respectively provided on both sides of the intermediate folded edge 44. The positioning posts 411 on both sides of the intermediate folded edge 44 protrude towards the side where the first connecting rod 1 and the second connecting rod 2 are located. The first connecting rod 1 and the second connecting rod 2 are both provided with positioning holes 412. The positioning holes 412 are located in the middle of the first connecting rod 1 and the second connecting rod 2, avoiding the position of the flanges. The positioning posts 411 can be inserted into the positioning holes 412 to form a pre-position.

[0026] Additionally, the connector 3 includes a hinge portion 31 and a connecting portion 32, wherein the hinge portion 31 extends from the ends of the first connecting rod 1 and the second connecting rod 2, and the hinge portion 31 is used for hinged connection with other Bailey plate connecting devices, while the connecting portion 32 is connected to the first connecting rod 1 and the second connecting rod 2, wherein the two sides of the connecting portion 32 abut against the inner sides of the first connecting rod 1 and the second connecting rod 2 respectively.

[0027] Meanwhile, to facilitate the connection of the connector 3 with the first connecting rod 1 and the second connecting rod 2, a first limiting platform 321 is provided on both sides of the connecting part 32. The first limiting platform 321 protrudes from the surface of the connecting part 32. When the connector 3 is inserted between the first connecting rod 1 and the second connecting rod 2, the first limiting platforms 321 on both sides of the connecting part 32 can abut against the ends of the first connecting rod 1 and the second connecting rod 2 respectively. The first limiting platform 321 forms a limiting relationship with the first connecting rod 1 and the second connecting rod 2, thereby achieving pre-positioning, preventing displacement, and facilitating subsequent welding.

[0028] In addition, see Figure 1 and Figure 3 When connected to the connector 3 of another Bailey plate connecting device, the other end of the Bailey plate connecting device also includes a reinforcing plate 5. The reinforcing plate 5 is respectively disposed at the end of the first connecting rod 1 and the second connecting rod 2 away from the connector 3, and is used to reinforce that end of the first connecting rod 1 and the second connecting rod 2 to improve the strength of the connection. The side of the reinforcing plate 5 can abut against the side of the first connecting rod 1 and the second connecting rod 2.

[0029] When connecting the reinforcing plate 5, both the first connecting rod 1 and the second connecting rod 2 have a plate groove 11 on one side. The reinforcing plate 5 can be inserted into the plate groove 11, and one side of the reinforcing plate 5 can abut against the side wall of the plate groove 11. Then, welding is performed to connect the reinforcing plate 5 with the first connecting rod 1 and the second connecting rod 2 into a whole. To facilitate the welding of the reinforcing plate 5, a second limiting platform 51 is provided on one side of the reinforcing plate 5. The second limiting platform 51 protrudes from the side wall of the reinforcing plate 5. After the reinforcing plate 5 is inserted, the second limiting platform 51 can abut against the ends of the first connecting rod 1 and the second connecting rod 2, thereby forming a pre-position, preventing displacement, and facilitating subsequent welding.

[0030] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications are also considered to be within the protection scope of the present utility model.
