Description

Technical Field

[0001] The utility model relates to the technical field of connecting devices, in particular to a connecting device for a Bailey beam and an I-beam. Background Art

[0002] In bridge construction, especially in the construction of temporary bridges or piers, the connection between Bailey beams and I-beams is a critical link. These structures are often used to support construction loads, traffic loads, and other possible loads.

[0003] In the process of connecting Bailey beams and I-beams, welding is widely used as a common connection method to ensure the overall stability and bearing capacity of the structure.

[0004] However, during the welding process, a technical difficulty is often encountered: positional offset is prone to occur between the Bailey beam and the I-beam. This offset will prevent the preset welding interface between the two from being accurately aligned, resulting in misalignment of the welded parts. The misalignment of the welded parts not only directly affects the strength and toughness of the welded joint, but may also further weaken the integrity and safety performance of the entire structure, posing a potential threat to the quality of the project. Therefore, taking effective measures to prevent and control positional offset during welding and ensure the precise alignment of the welding parts of the Bailey beam and the I-beam are key links in improving welding quality and structural safety. To this end, a connection device for the Bailey beam and the I-beam is proposed. Utility Model Content

[0031] Example 1

[0032] like Figure 1-4 As shown, the embodiment of the present invention provides a Bailey beam and I-beam connection device, comprising:

[0033] A first rod body (1), wherein a first fixing plate (14) is fixedly connected to the top of the first rod body (1), and a first V-shaped groove (15) is formed on one side of the first fixing plate (14);

[0034] A second rod body (2) is connected to the first rod body (1) via a connecting mechanism (3); a second fixing plate (21) is provided on the top of the second rod body (2); and a second V-shaped groove (22) adapted to the first V-shaped groove (15) is provided on one side of the second fixing plate (21);

[0035] The connecting mechanism (3) is capable of adjusting the distance between the first rod (1) and the second rod (2), and fixing the positions of the first rod (1) and the second rod (2);

[0036] In the above embodiment, when welding the Bailey beam and the I-beam, the connection position of the Bailey beam and the I-beam is first calibrated, then the second rod body 2 is stretched, the positions of the first fixing plate 14 and the second fixing plate 21 are adjusted, and then the first V-groove 15 and the second V-groove 22 are clamped at the connection between the Bailey beam and the I-beam. The positions of the first fixing plate 14 and the second fixing plate 21 are fixed by the connecting mechanism, thereby effectively preventing and controlling the positional deviation of the Bailey beam and the I-beam during the welding process.

[0037] In this embodiment, the number of the first rod body 1 and the second rod body 2 is only one, and the positions of the first fixing plate 14 and the second fixing plate 21 are fixed by bidirectional clamping.

[0038] Example 2

[0039] like Figure 1-4 As shown, the embodiment of the present invention provides a Bailey beam and I-beam connection device. Unlike the first embodiment, the number of the connecting mechanism 3, the second rod body 2 and the slider 13 are two. By rotating the two second rod bodies 2, a triangular distribution is achieved with the first rod body 1 to complete the position fixation of the first fixing plate 14 and the second fixing plate 21. This method has a better fixing effect.

[0040] Specifically, the second fixing plate 21 is rotatably connected to the second rod body 2 so that the second V-shaped groove 22 can be clamped at the connection between the Bailey beam and the I-beam;

[0041] A collar 11 is sleeved on the outer side of the first rod body 1, and a slide groove 12 is opened on the outer side of the collar 11. A slider 13 is slidably connected to the slide groove 12. The connecting mechanism 3 includes a third rod body 31 fixedly connected to the slider 13 and a fourth rod body 34 sliding inside the third rod body 31. The fourth rod body 34 is fixedly connected to the second rod body 2. The position of the connecting mechanism 3 can be adjusted by the slider 13 to achieve the purpose of adjusting the position of the second rod body. In addition, by sliding the fourth rod body 34, the distance between the first rod body 1 and the second rod body 2 can be adjusted.

[0042] Specifically: a blind hole 32 is formed on one side of the third rod 31, and the fourth rod 34 is located inside the blind hole 32. A threaded hole 35 is formed on the outer side of the third rod 31, and a knob 36 is connected to the inner thread of the threaded hole 35. After adjusting the distance between the first rod 1 and the second rod 2, the position of the fourth rod 34 is defined by rotating the knob 36, thereby defining the position of the first rod 1 and the second rod 2.

[0043] Specifically, an elastic member 33 is provided inside the blind hole 32 , and one end of the elastic member 33 is fixed to one end of the fourth rod 34 , so that after the fourth rod 34 is slid, the elastic member 33 can complete the reset of the fourth rod 34 .

[0044] When the utility model is in operation: first, the spacing between the first rod body 1 and the second rod body 2 is adjusted by sliding the fourth rod body 34, and then the first V-groove 15 and the second V-groove 22 are clamped in the connection between the Bailey beam and the I-beam. Under the elastic tension of the elastic member 33, the first V-groove 15 and the second V-groove 22 can be made to stick to the connection between the Bailey beam and the I-beam. Finally, by turning the knob 36, the position of the fourth rod body 34 is defined, thereby defining the position of the first rod body 1 and the second rod body 2, effectively preventing and controlling the positional deviation of the Bailey beam and the I-beam during welding, ensuring the precise alignment of the welding parts of the Bailey beam and the I-beam, and improving the welding quality and structural safety. When disassembling, the first fixing plate 14 and the second fixing plate 21 can be removed by simply turning the knob 36 in the opposite direction.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
