Technical Field

[0001] The present invention relates to the field of steel bridge deck paving, and particularly relates to a steel bridge deck paving structure and a paving method thereof. Background Art

[0002] The steel bridge deck paving is on a steel plate with large and complex deformations. The vibration, deformation, etc. of the steel plate itself will directly affect the working condition of the paving; due to being exposed on the sea with a more complex environmental climate, the steel plate has a relatively large thermal conductivity, so that the extreme temperature received by the paving layer is much higher than that of the paving layer of a general road surface. Therefore, there are great differences between the steel bridge deck paving and the general road paving. The conventional road surface structure cannot meet its requirements. Especially when the steel bridge deck vibrates and deforms, the paving efficiency and effect are greatly reduced. Summary of the Invention

The squeezing lock rod is a bent rod inserted into the arc-shaped connecting groove.

[0008] Preferably, there are anti-slip grooves on the surfaces of the squeezing lock rods. The anti-slip grooves are annular grooves recessed inward from the surfaces of the squeezing lock rods. The anti-slip grooves are distributed at intervals in the extending direction of the squeezing lock rods.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] As Figures 1 to 8As shown in the figure, a steel bridge deck paving structure includes a paving single block 1, which is a rectangular panel. There are an embedding groove and a connecting part 2 on the paving single block 1. The connecting part 2 includes a protruding rod and a filling ball. The protruding rod is a cylindrical rod that horizontally protrudes outward from the side surface of the paving single block 1, and the filling ball is a spherical block connected to the outer end of the protruding rod. The embedding groove includes a bottom profile groove 3, a surrounding groove 4, and a radiation cavity 5. The bottom profile groove 3 is a groove extending upward from the bottom surface of the paving single block 1, and the bottom profile groove 3 is consistent with the profile of the connecting part 2 to enable the connecting part 2 to enter. The surrounding groove 4 is a spherical cavity groove, and the radiation cavity 5 is a frustum groove that extends from the wall surface of the surrounding groove 4 toward the side surface of the paving single block 1 and has a gradually increasing diameter. The upper end of the profile groove 3 communicates with the lower ends of the surrounding groove 4 and the radiation cavity 5. When laying the paving single block 1 on the steel bridge deck, adjacent paving single blocks 1 are connected through the connecting part 2 and the embedding groove, that is, the connecting part 2 is pushed into the surrounding groove 4 and the radiation cavity 5 from the profile groove 3. In this way, adjacent paving single blocks 1 are connected, and the surrounding groove 4 and the radiation cavity 5 enable multi-angle rotation between the connected paving single blocks 1 to cooperate with the vibration, deformation, etc. of the steel bridge itself.

[0033] There are rough lines on the surface of the surrounding groove 4. The rough lines are staggered concave strips that are recessed inward from the surface of the surrounding groove 4. The surface of the surrounding groove 4 increases the roughness through the rough lines. After contacting the filling ball, it can prevent easy rotation due to overly smooth contact. When the paving single block 1 is squeezed or affected by external forces and rotates relative to each other, it plays a buffering and resisting effect.

[0034] It also includes a locking part to prevent the connecting part 2 from exiting the embedding groove.

[0035] The locking part includes an arc-shaped connecting groove and a squeezing lock rod 6. The arc-shaped connecting groove is an arc-shaped through groove that extends from the wall surface of the surrounding groove 4 toward the inner side of the paving single block 1 to the inner surface of the profile groove 3. The squeezing lock rod 6 is a bent rod inserted into the arc-shaped connecting groove. In the initial state, the upper end of the squeezing lock rod 6 protrudes from the upper opening of the arc-shaped connecting groove until it is contacted and squeezed by the filling ball and moves toward the lower opening of the arc-shaped connecting groove. When the filling ball completely enters the surrounding groove 4, the lower end of the squeezing lock rod 6 protrudes from the lower opening of the arc-shaped connecting groove and abuts against the lower side of the filling ball, thereby preventing the filling ball from detaching from the surrounding groove 4 and achieving self-locking. Specifically, if it is necessary to replace the paving single block 1, the squeezing lock rods 6 of the paving single block 1 where it is located and the squeezing lock rods 6 of the adjacent paving single blocks 1 can be cut off, the paving single block 1 to be replaced can be taken out, the cut-off squeezing lock rods 6 of the adjacent paving single blocks 1 can be taken out, new squeezing lock rods 6 can be inserted, and then the new paving single block 1 can be embedded directly between the two adjacent paving single blocks 1.

[0036] There is an anti-skid groove 9 on the surface of the push-pull lock rod 6. The anti-skid groove 9 is an annular groove that is recessed inward from the surface of the push-pull lock rod 6. The anti-skid groove 9 is spaced apart in the extension direction of the push-pull lock rod 6. The anti-skid groove 9 can not only increase the friction between the push-pull lock rod 6 and the surface of the arc-shaped connecting groove, and prevent the push-pull lock rod 6 from slipping out of the connecting opening of the contour groove 3 of the arc-shaped connecting groove during the paving process, but also prevent the push-pull lock rod 6 from slipping and causing dangerous accidents when the push-pull lock rod 6 is cut when the paving single block 1 is removed or replaced, that is, when the cutting point is positioned at the anti-skid groove 9, the cutting process of the push-pull lock rod 6 can be ensured to be stable.

[0037] The end of the push-pull lock rod 6 is provided with a concave veneer, and the concave veneer is a spherical surface that is concave inward from the end of the push-pull lock rod 6.

[0038] The paving block 1 has an angle bearing surface, which is an arc-shaped convex surface that bends and extends from the edges of the sides of the paving block 1 to the upper surface, the bottom surface and the side surface. The angle bearing surface is like a rounded corner, which can prevent the edges of the paving block 1 from seriously interfering when rotating, and has a certain extrusion margin.

[0039] There are also seepage grooves 7 on the surface of the paving block 1, which are grooves extending from the middle of the upper surface of the paving block 1 to the sides and gradually increasing in depth, and the seepage grooves 7 are distributed at intervals. The seepage grooves 7 help drain water and prevent water from accumulating on the surface of the paving block 1 and causing slipping.

[0040] There is also a slot inter-plate 8 in the seepage groove 7, which is a hollow plate connecting the two side walls of the seepage groove 7. The hollow holes of the slot inter-plate 8 are circular holes, which not only increase the support strength between the seepage grooves 7, but also play a certain supporting role in the later paving of the surface of the single block 1 with asphalt.

[0041] like Figure 9 As shown, a paving method for a steel bridge deck paving structure includes the following steps: S1, grinding and cleaning the steel bridge deck, and placing the paving blocks on the steel bridge deck in sequence; S2, pushing the connecting portion of the paving block to be paved from the contour groove of another paving block into the surrounding groove and the radiation cavity; S3, lifting one side of the embedded groove of the paving block just paved, and connecting the paving blocks to be connected according to step S2; S4, spraying the completed paving blocks to complete the paving.
