[0002] When constructing concrete roads, in order to protect the rivers and pipelines in the regular gaps of the road, it is usually necessary to set up Bailey bridges above the rivers and pipelines. The Bailey bridges are usually placed on reinforced concrete beams, resulting in a large gap at the joint between the bridge deck of the Bailey bridge and the pavement of the reinforced concrete road. When heavy vehicles such as concrete vehicles pass through, the joints will cause the road surface and the bridge deck to bear a large impact force, resulting in unreliable connection, and also causing a large vibration effect on the driving of heavy vehicles, affecting the stability of the heavy vehicle's own structure and the cargo loaded inside.

[0016] The utility model is described in detail below in conjunction with the accompanying drawings: According to the following description, the advantages and features of the utility model will be more clearly understood. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0017] Please refer to Figure 1 to Figure 2 The embodiment of the utility model provides a joint structure 400 of a bailey bridge and a concrete road, comprising a bailey bridge 300 and a concrete road 100, wherein a steel plate 410 extending outward and not connected to the concrete road 100 is welded below the bridge deck of the bailey bridge 300 at the joint between the concrete road 100 and the bailey bridge 300, and a filling block 420 placed on the steel plate 410 is arranged at the joint between the concrete road 100 and the bailey bridge 300, wherein the filling block 420 is an integrated structure consisting of a concrete block 421 and a rubber block 422, and the rubber block 403 is located on one side of the concrete road 100.

[0018] The joint structure 400 of the Bailey bridge and concrete road provided by the embodiment of the utility model is arranged at the joint of the Bailey bridge 300 and the concrete road 100, and is composed of a steel plate 410 welded on the Bailey bridge 300 and not connected to the concrete road 100, and a filling block 420 thereon. When a heavy vehicle passes by, the vertical load is borne by the concrete block 402, and the lateral deformation is borne by the rubber block 422, which reduces the impact force on the joint when the heavy vehicle passes by, ensures the reliable connection between the Bailey bridge 300 and the concrete road 100, reduces the impact force on the heavy vehicle's own structure and the cargo loaded therein, improves the stability of the heavy vehicle's driving, and ensures driving safety.

[0019] The rubber block 422 is located on one side of the concrete road 100 , and the concrete block 421 is located on one side of the Bailey bridge 300 . Since the main center of gravity of the filling block 42 is on the concrete block 421 , the positions of the rubber block 422 and the concrete block 421 are not interchangeable.

[0020] In order to improve the service life, the joint structure 400 of the Bailey bridge and concrete road provided by the embodiment of the utility model, the rubber block 422 can be EVA rubber. EVA rubber is a polymer material, which is copolymerized by ethylene (E) and vinyl acetate (VA), so that the joint has flexibility and elasticity, good weather resistance, aging resistance and corrosion resistance, and improves the service life of the joint. The thickness of the EVA rubber sheet must be calculated, and the thickness of the EVA rubber sheet that can be deformed is required to be slightly greater than the reasonable lateral deformation of the Bailey bridge.

[0021] In order to facilitate the construction of road development, the embodiment of the utility model provides a joint structure 400 of a Bailey bridge and a concrete road, wherein the concrete road 100 is a cast-in-place concrete structure.

[0022] In order to improve the structural stability of the Bailey bridge 300 and protect the rivers, pipelines, etc. below it, the embodiment of the utility model provides a Bailey bridge and concrete road joint structure 400, wherein the Bailey bridge 300 is arranged on a structural beam 200. In order to improve the supporting strength, the structural beam 200 may be a reinforced concrete structure.

[0023] In the joint structure 400 of the Bailey bridge and concrete road provided by the embodiment of the utility model, the concrete block 402 is slightly higher than the rubber block 422. The concrete block 402 is slightly higher than the rubber block 422, which can improve the structural strength of the joint and meet the bearing capacity requirements of vehicle traffic. At the same time, the rubber block 422 is not easily worn out by friction of heavy vehicles, thereby improving its service life.

[0024] The construction method of the Bailey bridge and concrete road joint structure 400 provided in the embodiment of the utility model may include the following steps:

[0025] The first step is to construct the access road according to the design requirements, including concrete road and Bailey bridge.

[0026] The second step is to measure the actual seam position, width, depth and other data.

[0027] The third step is to support the formwork of the concrete block and cover it with EVA rubber blocks to ensure that the concrete block has the appropriate width and depth to fit into the joint position, and that the EVA rubber block has sufficient width to allow the Bailey bridge to deform laterally.

[0028] The fourth step is to weld the steel plate 410 under the deck of the Bailey bridge for placing the concrete block 421 and the rubber block 422. The weld of the steel plate 410 is required to be continuous and full, and the weld strength must be calculated to be able to resist the impact of the vehicle.

[0029] The fifth step is to place the integrated structure composite plate composed of concrete blocks and rubber blocks manufactured in the third step on the steel plate 410 at the joint.

[0030] This construction method is based on the fact that Bailey bridges and concrete pavements are prone to have large joints, which affects vehicle traffic. After the bridge deck is installed, the joint structure 400 is constructed to fill the gap at the joint without destroying the freedom of the Bailey bridge. It has the advantages of simple operation, safety and reliability.

[0031] The present utility model is not limited to the above-mentioned specific implementation modes. Obviously, the above-mentioned embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the described embodiments of the present utility model belong to the scope of protection of the present utility model. Those skilled in the art can make other levels of modifications and changes to the present utility model. In this way, if these modifications and changes of the present utility model fall within the scope of the claims of the present utility model, the present utility model is also intended to include these changes and changes.
