Figure 1 As shown, the bridge includes multiple parallel concrete bridge deck panels 1, each a reinforced concrete slab. Multiple butt joints 2 are provided along the edges of the concrete bridge deck panels 1, arranged equidistantly along their edges. When the multiple concrete bridge deck panels 1 are in place, the butt joints 2 on the adjacent edges of two adjacent panels are aligned. A connecting component 3 is provided between adjacent concrete bridge deck panels 1 to fix the aligned butt joints 2 in place.

[0026] like Figure 1 , 2As shown in Figure 3, the connecting piece 2 is a snap-fit ​​block 21. Multiple mounting slots 11 are provided along the edge of the concrete bridge deck 1, with each mounting slot 11 for a connecting piece 2 to be inserted. The snap-fit ​​block 21 is a C-shaped steel component, comprising an integrally formed bottom plate 211 and a slot plate 212. The bottom plate 211 is an arc-shaped panel, and there are two slot plates 212 located at opposite ends of the bottom plate 211. A connecting groove 22 is formed on the snap-fit ​​block 21 through the slot plates 212 and the bottom plate 211. The surface of the slot plates 212 is perpendicular to the surface of the concrete bridge deck 1, and the opening of the connecting groove 22 is located between the two slot plates 212. The surface of the mounting groove 11 is also arc-shaped, and the side of the bottom plate 211 facing away from the slot plates 212 is in contact with the surface of the mounting groove 11. An embedded steel bar 12 is fixedly connected to the side of the bottom plate 211 away from the opening plate 212. The embedded steel bar 12 passes through the bottom of the installation groove 11 and is welded and fixed to the steel mesh inside the concrete bridge deck 1 (not shown in the figure) to strengthen the connection between the snap-fit ​​block 21 and the concrete bridge deck 1. The side of the opening plate 212 away from the bottom plate 211 is flush with the side wall of the concrete bridge deck 1.

[0027] like Figure 2 and 3 As shown, the connecting component 3 includes a tie block 31. In its vertical projection, the tie block 31 is H-shaped and includes an intermediate body 311 and two abutting pull blocks 312. The two abutting pull blocks 312 are integrally formed at opposite ends of the intermediate body 311. The tie block 31 is placed between two concrete bridge decks 1. The intermediate body 311 spans the openings of two mating grooves 22. A single abutting pull block 312 is located within one mating groove 22. The abutting pull block 312 and the groove plate 212 abut against the side facing the groove bottom plate 211. That is, the relative distance between the two mutually aligned locking blocks 21 is determined, and the distance between the two concrete bridge decks 1 is also determined.

The pair of supporting rollers 32 are rotationally connected with the mounting frame 33, the rotation axis is horizontal and parallel to the arrangement direction of the two slot plates 212 on the same abutting block 21. The pair of supporting rollers 32 are multiple, two of which form a group, and there are four groups which are evenly distributed on both sides of the intermediate body 311, the two groups of supporting rollers 32 on the same side are arranged vertically, the two supporting rollers 32 in a single group are parallel to each other and the wheel surfaces thereof abut against each other, the arrangement direction is perpendicular to the plate surface of the slot plate 212; the wheel surface of a single supporting roller 32 and the plate surface of a slot plate 212 rollingly abut against each other. When the two adjacent concrete bridge deck slabs 1 are placed in position, the distance therebetween is determined by adjusting the pair of supporting rollers 32: in the process of inserting the counter-pulling block 31 from top to bottom between the two abutting blocks 21, the abutting pulling block 312 and the pair of supporting rollers 32 abut against the opposite sides of a slot plate 212 respectively, when the upper surface of the counter-pulling block 31 is flush with the upper surface of the abutting block 21, the slot plate 212 of one abutting block 21, the pair of supporting rollers 32, the other supporting roller 32 in the same group and the slot plate 212 of the other abutting block 21 abut against each other in turn, then the relative distance of the two abutting blocks 21 is determined, and when the relative distances of all the abutting blocks 21 which are aligned with each other are determined, the relative distance of the two adjacent concrete bridge deck slabs 1 is also finally determined.

[0029] As Figure 1 , 3When the distance between the two concrete bridge deck slabs 1 is relatively fixed, the mounting bolt 34 can be loosened to remove the mounting frame 33 and the supporting roller 32. The intermediate body 311 is slidably connected with a retreat-preventing sliding block 35, the sliding direction of the retreat-preventing sliding block 35 is perpendicular to the inserting direction of the abutting block 31 relative to the clamping block 21 and parallel to the axis of the supporting roller 32. The edge of the slot plate 212 is provided with a retreat-preventing slot 23 for the retreat-preventing sliding block 35 to be inserted into, when the upper surface of the abutting block 31 is flush with the upper surface of the clamping block 21, the retreat-preventing sliding block 35 is aligned with the slot of the retreat-preventing slot 23; the intermediate body 311 is provided with an automatic spring 36, one end of the automatic spring 36 is connected with the retreat-preventing sliding block 35 and the other end is connected with the intermediate body 311, in the natural state, the automatic spring 36 can exert a spring force on the retreat-preventing sliding block 35 to make the retreat-preventing sliding block 35 enter the retreat-preventing slot 23. The end of the mounting bolt 34 is fixedly provided with a conical surface body 341, the retreat-preventing sliding block 35 is fixedly connected with a force wedge 351, when the mounting bolt 34 is threadedly connected with the intermediate body 311, the conical surface and the wedge surface of the force wedge 351 abut and the retreat-preventing sliding block 35 is retracted into the intermediate body 311, so that the cooperation between the intermediate body 311 and the slot of the abutting groove 22 is not affected. When the mounting bolt 34 is removed, the retreat-preventing sliding block 35 can be popped out and enter the retreat-preventing slot 23, at this time, due to the limiting effect of the retreat-preventing sliding block 35, the abutting block 31 cannot be pulled out, and the abutting block 31 and the clamping block 21 are relatively fixed.

[0030] As shown in Figure 1 The edges of the two adjacent concrete bridge deck slabs 1 should form a uniform gap of 3 cm, the edges of the concrete bridge deck slab 1 are fixedly bonded with a plurality of elastic pads 4 made of rubber material, at the edge of a single concrete bridge deck slab 1, a single elastic pad 4 is located between the two adjacent clamping blocks 21; after the two concrete bridge deck slabs 1 are arranged relative to each other, the elastic pads 4 at the edges of the two concrete bridge deck slabs 1 abut each other to block most of the gap between the two concrete bridge deck slabs 1, and the elasticity of the elastic pads 4 can make the gap between the two concrete bridge deck slabs 1 have a certain shrinkage deformation ability. The upper surfaces of the clamping block 21 and the abutting block 31 are lower than the upper surface of the concrete bridge deck slab 1, and the elastic cover plate 5 made of rubber material is attached above the clamping block 21 and the abutting block 31 in the mounting groove 11, the upper surface of the elastic cover plate 5 is flush with the upper surface of the concrete bridge deck slab 1, which is used to close the abutting piece 2 and the connecting assembly 3, reduce the influence of external environmental factors on the connecting structure, and improve the stability of the connecting structure.

[0031] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
