[0038] When installing panels across high-speed bridges, they are usually positioned using pre-buried steel bars. During the actual installation process, the shaking of the panels makes it difficult to position them, requiring installers to make repeated adjustments. However, since the bridge panels are heavy and inconvenient to adjust, it is difficult to position the entire panel.

[0039] The main purpose of the utility model is to provide a bridge deck assembly and a high-speed bridge, aiming at least to solve the technical problem that the bridge deck is difficult to position in the related art.

[0040] See also Figure 1 and Figure 2In one embodiment of the utility model, a bridge panel assembly 100 includes a plurality of panel bodies and a positioning structure 3, wherein the plurality of panel bodies include at least a first panel body 1 and a second panel body 2 distributed along the length direction, and the positioning structure 3 includes a positioning shaft 31 and a positioning hole 32, wherein the positioning shaft 31 and the positioning hole 32 are respectively arranged at opposite ends of the first panel body 1 and the second panel body 2, and the outer diameter of the positioning shaft 31 gradually decreases in the direction approaching the other second panel body 2, and the positioning hole 32 and the positioning shaft 31 are adapted to each other.

[0041] In the technical solution of the present utility model, the positioning shaft 31 and the positioning hole 32 are respectively arranged at the opposite ends of the first panel body 1 and the second panel body 2, and the outer diameter of the positioning shaft 31 gradually decreases in the direction approaching the other second panel body 2, and the positioning hole 32 and the positioning shaft 31 are adapted to each other; in this way, since the outer diameter of the positioning shaft 31 gradually decreases, the positioning shaft 31 as a whole is conical, and the positioning hole 32 as a whole is adapted to the positioning shaft 31, usually in a conical shape, that is, the inner diameter at the opening of the positioning hole 32 is larger than the outer diameter of the end of the positioning shaft 31 away from the first panel body 1, so it can be easily aligned, that is, the second panel body 2 can be sleeved on the positioning shaft 31 through the positioning hole 32, and in the process of the second panel body 2 gradually approaching, the tapered positioning shaft 31 and the positioning hole 32 cooperate to play a guiding role until the first panel body 1 and the second panel body 2 are completely positioned, so that the installation between the panels of the bridge is more convenient and quick.

[0042] Even if the inner diameter of the opening of the positioning hole 32 is larger than the outer diameter of the end of the positioning shaft 31, there is still a situation where the second panel body 2 is not aligned at one time. During the docking process, the second panel body 2 may cause its side to collide with the positioning shaft 31 when shaking, thereby causing damage to the positioning shaft 31. Therefore, in the embodiment of the present utility model, please refer to Figure 2 The positioning shaft 31 is rotatably arranged along the axis extending in the thickness direction at the end of the first panel body 1; with such arrangement, when the side of the second panel body 2 collides with the positioning shaft 31, the positioning shaft 31 will rotate accordingly instead of rigidly colliding with the second panel body 2, thereby reducing the possibility of damage to the positioning shaft 31. In the subsequent adjustment process, the rotating positioning shaft 31 can be reset.

[0043] To facilitate the resetting of the positioning shaft 31, in an embodiment of the utility model, a torsion spring 34 is arranged at the rotational connection between the positioning shaft 31 and the first panel body 1; with such arrangement, after the positioning shaft 31 is collided and rotated, a part of the kinetic energy will be converted into the elastic potential energy of the torsion spring 34, and after the second panel body 2 is separated from the positioning shaft 31, the elastic potential energy stored in the torsion spring 34 drives the positioning shaft 31 to rotate to reset. In this way, there is no need to manually reset the positioning shaft 31, which reduces labor and improves the installation efficiency of the first panel body 1 and the second panel body 2.

[0044] Since the positioning shaft 31 needs to be rotatably connected to the first panel body 1, there must be a rotating connection structure between the two that affects the splicing of the first panel body 1 and the second panel body 2, resulting in a larger distance between the two when they are completely spliced; in order to ensure that the rotation of the positioning shaft 31 does not affect the distance between the first panel body 1 and the second panel body 2, in an embodiment of the utility model, the positioning structure 3 also includes a hinge seat 33 fixedly installed on one end of the first panel body 1 facing the second panel body 2, the positioning shaft 31 rotates on the hinge seat 33, and the end of the second panel body 2 facing the first panel body 1 is provided with a receiving groove 21 that is compatible with the hinge seat 33; in this way, the hinge seat 33 is hidden by the receiving groove 21 on the second panel body 2, so that it will not interfere with the installation of the first panel body 1 and the second panel body 2; the present design is not limited to this. In another embodiment, the receiving groove 21 can be set at one end of the first panel body 1 facing the second panel body 2, and the hinge seat 33 is directly installed in the receiving groove 21 on the first panel body 1.

[0045] When the positioning hole 32 and the positioning axis 31 are not aligned, the end of the second panel body 2 facing the first panel body 1 may collide with the end of the positioning axis 31. In order to reduce the possibility of damage to the positioning axis 31 caused by the collision, in an embodiment of the utility model, the positioning axis 31 is retractable in the length direction of the panel body; with this arrangement, after the end of the positioning axis 31 collides, the positioning axis 31 is adaptively retracted to avoid damage caused by rigid collision.

[0046] In order to realize the extension and retraction of the positioning shaft 31, in an embodiment of the utility model, the positioning shaft 31 includes a fixed portion 311 and a sliding portion 312, wherein the fixed portion 311 is arranged on the first panel body 1, and a sliding hole is arranged at one end of the fixed portion 311 away from the first panel body 1, and the sliding portion 312 is slidably installed in the sliding hole along the length direction of the panel body; thus, after the end of the sliding portion 312 away from the first panel body 1 collides with the second panel body 2, the sliding portion 312 slides along the direction of the sliding hole super close to the first panel body 1 to reduce the possibility of damage. The present design is not limited to this, and the part of the positioning shaft 31 close to the end can be set to an elastic material, which itself elastically expands and contracts to buffer during collision.

[0047] In order to facilitate the reset of the sliding part 312 after the movement, please refer to Figure 2 In the present invention, a reset member 313 is provided between the inner wall of the sliding hole and the sliding portion 312, and the reset member 313 is used to provide a driving force for the sliding portion 312 to slide in a direction away from the first panel body 1. The reset member 313 can automatically reset the sliding portion 312 when it is hit and slides, without manual reset.

[0048] The reset member 313 has various forms, such as Figure 1 and Figure 2 As shown, in some embodiments, the reset member 313 may be a spring, and the two ends of the spring are respectively connected to the inner bottom wall of the sliding hole and the end of the sliding portion 312; in other embodiments, the reset member 313 may be a magnetic member of like charges that repel each other.

[0049] It can be understood that when the second panel body 2 is spliced ​​with the first panel body 1 along the length direction, it will rotate in the horizontal direction, and the single positioning axis 31 and the positioning hole 32 cannot limit the rotation of the second panel body 2 relative to the first panel body 1, which may affect the accuracy of the final positioning. Therefore, in this embodiment, the positioning axis 31 is provided in plurality along the width direction of the first panel body 1, and the positioning holes 32 are correspondingly provided in plurality. The rotation of the second panel body 2 is limited by the cooperation of the plurality of positioning axes 31 and the plurality of positioning holes 32, thereby ensuring the accuracy of positioning.

[0050] The utility model also proposes a high-speed bridge 1000, which includes a pier 4, a crossbeam 5 and a bridge deck assembly 100. The specific structure of the bridge deck assembly 100 refers to the above embodiment. Since the high-speed bridge 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. There are at least two piers 4, and the two piers 4 are arranged at intervals. The crossbeam 5 is arranged on the two piers 4, and the bridge deck assembly 100 is arranged on the crossbeam 5.

[0051] In the technical solution of the present utility model, the positioning shaft 31 and the positioning hole 32 are respectively arranged at the opposite ends of the first panel body 1 and the second panel body 2, and the outer diameter of the positioning shaft 31 gradually decreases in the direction close to the other second panel body 2, and the positioning hole 32 and the positioning shaft 31 are adapted; in this way, since the outer diameter of the positioning shaft 31 gradually decreases, the positioning shaft 31 is tapered as a whole, and the positioning hole 32 is adapted to the positioning shaft 31 as a whole, usually in a tapered shape, that is, the inner diameter of the opening of the positioning hole 32 is larger than the outer diameter of the end of the positioning shaft 31 away from the first panel body 1, so it can be easily aligned, that is, the second The panel body 2 is sleeved on the positioning shaft 31 through the positioning hole 32. In the process of the second panel body 2 gradually approaching, the tapered positioning shaft 31 and the positioning hole 32 cooperate with each other to play a guiding role until the first panel body 1 and the second panel body 2 are completely positioned. This arrangement makes the installation of the bridge panels more convenient and quick. When the highway-spanning bridge 1000 is actually constructed, the piers 4 are first built on both sides of the highway, and then the beams 5 are built on the two piers 4. Then, the bridge panel assembly 100 is formed on the beams 5 by splicing the multiple panel bodies. This can realize the construction of a bridge across the highway.

[0052] There are many types of bridges. Further, in this embodiment, the crossbeam 5 includes a steel truss; two bridge deck assemblies 100 are provided, one of which is provided at the upper end of the steel truss and the other is provided at the lower end of the steel truss. In this way, the space can be used more reasonably. The upper bridge deck assembly 100 can be used as a road for vehicles, and the lower bridge deck assembly 100 can be used as a pedestrian road.
