[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-5 The utility model provides a spliced ​​concrete pavement panel, comprising a pavement panel body 1, a strip splicing body 3 arranged on one side of the pavement panel body 1 and a long splicing groove 6 arranged on the other side of the pavement panel body 1. The strip splicing body 3 matches the long splicing groove 6, so that between two adjacent pavement panel bodies 1, the long splicing groove 6 of one pavement panel body 1 can be spliced ​​with the strip splicing body 3 of another pavement panel body 1 by plugging, snapping or disassembling the connection, so that multiple pavement panel bodies 1 are spliced ​​and paved in sequence to form a road surface; the structure is simple and the operation is convenient, so that the overall paving efficiency can be improved while ensuring the paving effect.

[0029] Furthermore, a fastener 2 is provided on the strip splicing body 3 so that the strip splicing body 3 can be detachably connected to the long splicing groove 6 through the fastener 2. The connection is stable and reliable, avoiding the road surface gap being too large to affect the use and ensuring the use requirements.

[0030] Specifically, an embedded groove 10 is opened on the strip-shaped splicing body 3, so that the bottom of the fastener 2 passes through the embedded groove 10 and extends to the bottom of the strip-shaped splicing body 3, and the top of the fastener 2 is located in the embedded groove 10, ensuring the flatness of the surface of the road panel body 1 and avoiding protrusions that affect the use of the road surface. At the same time, it can also protect the fastener 2 and increase its service life.

[0031] Correspondingly, a fastening hole 8 is opened at the bottom of the long splicing groove 6 , and the fastening hole 8 matches the bottom of the fastener 2 . During the splicing process, the bottom of the fastener 2 passes through the strip splicing body 3 and extends into the corresponding fastening hole 8 .

[0032] Preferably, the number of fasteners 2 is at least two. When the number of fasteners 2 is two or more, all fasteners 2 are arranged in sequence at equal intervals along the length direction of the strip splicing body 3; similarly, the number of fastening holes 8 on the long splicing groove 6 is consistent with the number of fasteners 2, and the two are arranged in a one-to-one correspondence to ensure efficient splicing.

[0033] Further explanation: in order to avoid vertical deviation of the road panel body 1 after splicing, it is preferred to provide a clip structure at the bottom of the fastener 2. The fastener 2 utilizes the clip structure to engage with the fastening hole 8 to improve the splicing reliability of the road panel body 1.

[0034] Preferably, the clamping structure includes a clamping member 11, a limit block 15, an intermediate baffle and an elastic telescopic member 14; a limit cavity 12 is opened at the bottom of the fastener 2, and the number of the clamping members 11, the number of the limit blocks 15 and the number of the elastic telescopic members 14 are all two. The intermediate baffle is connected to the middle position of the limit cavity 12, and the two limit blocks 15 are located on opposite sides of the intermediate baffle. The limit blocks 15 are also slidably connected to the limit cavity 12, and the two elastic telescopic members 14 are respectively connected between the limit blocks 15 and the intermediate baffle. One end of the clamping member 11 is connected to the limit block 15, and the other end of the clamping member 11 passes through the limit cavity 12 and extends to the outside of the fastener 2.

[0035] In actual use, the clamping member 11 is squeezed from the outside to push the limit block 15 to compress the elastic telescopic member 14, so that the corresponding end of the clamping member 11 is close to the middle baffle, which facilitates the fastener 2 to extend into the fastening hole 8 for clamping.

[0036] Correspondingly, a fixing groove 13 is opened in the fastening hole 8, and the fixing groove 13 matches the fixing member 11, so that after the fixing member 11 extends downward to the position of the fixing groove 13, the fixing member 11 is connected with the fixing groove 13 under the action of the elastic telescopic member 14, further improving the reliability and stability of the connection between the two road panel bodies 1.

[0037] Preferably, an auxiliary mounting hole 4 is provided on the top of the fastener 2 for inserting the fastener 2 into the fastening hole 8 .

[0038] Further explanation, a dovetail splicing block 5 and a dovetail splicing groove 7 are also provided on the road panel body 1. The dovetail splicing block 5 and the dovetail splicing groove 7 match each other, so that the two road panel bodies 1 can be connected by the dovetail splicing block 5 on one road panel body 1 and the dovetail splicing groove 7 on the other road panel body 1.

[0039] The dovetail splicing block 5 and the dovetail splicing groove 7 are both located between the strip splicing body 3 and the long splicing groove 6, thereby enabling the pavement panel body 1 to be spliced ​​with pavement panel bodies 1 at different positions in the front, back, left and right directions.

[0040] The dovetail splicing block 5 can also be optionally arranged on the same side of the strip splicing body 3, and the dovetail splicing groove 7 is located on the same side of the long splicing groove 6, thereby further ensuring the splicing reliability of the opposite sides of the road panel body 1.

[0041] Preferably, the number of dovetail splicing blocks 5 is two, and the two dovetail splicing blocks 5 are located on opposite sides of the strip splicing body 3; similarly, the number of dovetail splicing grooves 7 is also two, and the two dovetail splicing grooves 7 are located on opposite sides of the long splicing groove 6, and the dovetail splicing blocks 5 and the dovetail splicing grooves 7 are arranged in a one-to-one correspondence.

[0042] After the splicing is completed, the gap between the dovetail splicing block 5 and the dovetail splicing groove 7 and the gap between the strip splicing body 3 and the long splicing groove 6 can be filled with asphalt filler to reduce the thermal expansion and contraction caused by weather and improve the splicing stability.

[0043] Furthermore, an anti-cracking layer 9 is laid on the upper end surface of the splicing position of the dovetail splicing block 5 and the dovetail splicing groove 7, and the upper end surface of the splicing position of the strip splicing body 3 and the long splicing groove 6, so that the splicing position of the two road panel bodies 1 is more stable and the cracking phenomenon on the surface of the road panel body 1 and the splicing structure is greatly reduced.

[0044] Working process:

[0045] Place adjacent road panel bodies 1 close to each other, use the dovetail splicing blocks 5 and the dovetail splicing grooves 7 of matching size to form a dovetail structure splicing connection, then the strip splicing body 3 is overlapped with the matching long splicing groove 6 to form an auxiliary splicing, and the force generated by the contact makes the spliced ​​and assembled road surface have good integrity.

[0046] Then fill the gaps at the splicing positions with asphalt filler. Filling the gaps with asphalt can reduce thermal expansion and contraction caused by weather conditions and improve splicing stability.

[0047] After applying force to the auxiliary installation hole 4 to rotate the fastener 2 into the embedded groove 10 and the fastening hole 8, the connected clamping member 11 is automatically plugged into the matching clamping groove 13.

[0048] After cleaning the surface of the road panel body 1, an anti-cracking layer 9 is pasted on the upper surface of the splicing position of adjacent road panel bodies 1 to make the splicing of the two road panel bodies 1 more stable.
