Description

Technical Field

[0001] The utility model relates to the field of assembled roads, in particular to a prefabricated assembled urban road pavement structure. Background Art

[0002] Prefabricated road pavement structure is a modern pavement construction technology that prefabricates various pavement components (such as concrete slabs, asphalt mixture slabs, etc.) in the factory and then transports them to the construction site for assembly and laying. Compared with traditional on-site pouring, this construction method has the advantages of fast construction speed, easy quality control, and low environmental impact. It is especially suitable for urban expressways, main roads, airport runways, and maintenance projects that require rapid restoration of traffic;

[0003] Traditional spliced ​​pavements have gaps due to the joints not being tight enough, which in turn causes the gaps to become larger and larger during driving due to the insufficient strength of the joints, thus putting some vehicles driving on it in danger. Utility Model Content

[0024] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0025] See also Figure 1-6The utility model provides an embodiment: a prefabricated assembled urban road pavement structure, including a steel film frame 10, wherein the bottom of the steel film frame 10 is evenly spaced and provided with rectangular protrusions 25, and the upper end surface of the rectangular protrusions 25 is installed with a steel mesh 11. When concrete is poured inside the steel film frame 10, the steel mesh 11 can strengthen the pavement structure, and the left end surface of the steel film frame 10 is provided with a side splicing part 12, and the side The front and rear ends of the splicing part 12 are respectively fixedly connected with the outer column part 13, and the upper end surface of the side splicing part 12 is slidably installed with two trapezoidal locking blocks 17, and each of the trapezoidal locking blocks 17 is respectively fixedly installed with a latch column 18 on the end surface away from the center line direction of the steel film frame 10, and the right end surface of the steel film frame 10 is provided with a splicing end 22, and a card slot 21 is provided between the front and rear end surfaces of the splicing end 22 and the edge of the steel film frame 10, and each of the outer column parts 13 and the inner cavity side wall of the card slot 21 are connected. The latch column 18 can slide through the latch hole 19, and the upper end surface of the splicing end 22 is provided with a locking groove 23, and the bottom of the locking groove 23 is provided with two through grooves 26, and a J-shaped locking block 24 is slidably installed in each through groove 26. When splicing two pavement structures, the slot 21 on one pavement structure is aligned with the outer column 13 on the other pavement structure, and then the two pavement structures are buckled together, and the outer column 13 is pressed into the slot 21, at this time, the bottom of the J-shaped locking block 24 slides into the upper end surface of the side splicing part 12 in the other pavement structure, and abuts against the corresponding trapezoidal locking block 17. At this time, the two J-shaped locking blocks 24 are slid to both sides, thereby abutting against the trapezoidal locking block 17 on the other pavement structure to slide away from the center line direction of the steel membrane frame 10, so that the pin column 18 slides through the locking hole 19 and locks the outer column part 13 in the slot 21.

[0026] It is worth mentioning that in order to facilitate the disassembly of the two spliced ​​pavement structures and to improve the stability during splicing, in the present embodiment, a protrusion 20 is provided on the end face of the trapezoidal locking block 17 close to the steel film frame 10, and two long slide grooves 16 are provided on the left end face of the steel film frame 10. Each of the protrusions 20 is slidably embedded in the corresponding long slide groove 16, and a return spring is connected between the end face of each protrusion 20 away from the center line direction of the steel film frame 10 and the corresponding side wall of the long slide groove 16, so that the stability of the trapezoidal locking block 17 during the sliding process is greatly improved. At the same time, when disassembly is required, after the two J-shaped locking blocks 24 are slid apart, the two trapezoidal locking blocks 17 will automatically reset, and then disassembly can be carried out, which is very convenient.

[0027] It should be noted that in order to further improve the stability during the splicing process, in the present embodiment, a locking plate slot 14 is provided on the upper end surface of the steel film frame 10 on one side of the side splicing portion 12, and a locking plate block 15 is slidably installed in the locking plate slot 14. When splicing, after the two J-shaped locking blocks 24 slide to both sides, the locking plate block 15 is pulled out and stuck in the locking slot 23, and the two ends are respectively abutted against the J-shaped locking blocks 24.

[0028] In addition, in one embodiment, the bottom end surface of the steel film frame 10 is provided with a concave cavity at the position of each of the rectangular raised portions 25, so as to reduce the erosion effect of rainwater to a certain extent.

[0029] In specific implementation, when two pavement structures are spliced, the slot 21 on one pavement structure is aligned with the outer column 13 on the other pavement structure, and then the two pavement structures are buckled together, and the outer column 13 is pressed into the slot 21. At this time, the bottom of the J-shaped locking block 24 slides into the upper end surface of the side splicing part 12 in the other pavement structure, and abuts against the corresponding trapezoidal locking block 17. At this time, the two J-shaped locking blocks 24 are slid to both sides, thereby abutting against the trapezoidal locking block 17 on the other pavement structure away from the center of the steel membrane frame 10. Slide on one side in the linear direction so that the latch column 18 slides through the locking hole 19, locks the outer column part 13 in the card slot 21, and then pulls out the locking piece block 15 and jams it in the locking slot 23, with both ends respectively abutting against the J-shaped locking blocks 24, so that by jamming the outer column part 13 into the other spliced ​​card slot 21, and pushing the top J-shaped locking block 24 to insert the latch column 18 into the locking hole 19 for locking, not only the splicing is made tighter, but also the connection strength of the splicing is greatly improved compared with the traditional splicing pavement structure, and it is also more convenient to disassemble.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
