Description

Technical Field

[0001] The present invention relates to the technical field related to municipal roads, and in particular to a paving stone for municipal roads. Background Art

[0002] Paving stones are widely used in road construction. They are divided into natural stones and artificial stones. This type of stone is used in landscape projects such as garden floors and square walkways, and is also used in the construction of curbstones on urban main roads. For example, a splicable paving stone with announcement number CN221320548U relates to the field of paving stone technology, including a paving stone body and a drainage mechanism. One side of the paving stone body is connected to spaced-apart plugs, and the other side of the paving stone body is provided with spaced-apart slots. The splicable paving stone can align the No. 1 splicing block on one side of the paving stone body with the No. 1 splicing groove on the side of the other paving stone body when laying the paving stone. Then, the No. 1 splicing block is slid into the No. 1 splicing groove from left to right, while driving the No. 2 splicing block to slide into the No. 2 splicing groove. This allows the two paving stone bodies to be spliced ​​together on one side. Then, the insert block on one side of the paving stone body is inserted into the slot on the side of the other paving stone body to splice the paving stone bodies again. The setting of the splicing mechanism improves the splicing efficiency, makes the gaps between the paving stones substantially the same in size, and improves the paving effect of the paving stone.

[0003] For example, there is an outdoor quick-install ecological paving stone with the announcement number CN222205899U. This outdoor quick-install ecological paving stone includes a paving stone base and a quick-install connector. The side of the paving stone base is provided with a connecting groove adapted to the quick-install connector. The bottom surface of each side of the bottom surface of the paving stone base has an inward-contracted chamfer. The quick-install connector includes a first connector and a second connector. The first connector and the second connector are detachably connected. When the two paving stone bases are spliced, the first connector is inserted into the connecting grooves of the two paving stones at the same time, and the second connector touches the chamfers of the two paving stone bases. Outdoor quick-install ecological paving stones can realize the rapid installation of multiple paving stone bases through quick-install connectors, improve the flexibility of paving, adapt to the installation requirements of different road environments, are not easy to loosen after being fixed, and improve the installation firmness. However, the above-mentioned paving stones still have the following disadvantages during actual use:

[0004] 1. When laying traditional paving stones, adjacent paving stones are bonded together using concrete. This makes splicing inconvenient and requires a long time for the concrete to dry, which can easily cause adjacent paving stones to shift. Furthermore, the gaps between paving stones vary in size after laying, affecting the overall aesthetics. Furthermore, when the paving stones need repair, a large amount of concrete adheres to the removed paving stones, making it difficult to clean and affecting subsequent recycling.

[0005] 2. When the paving stones are used in rainy days, rainwater will remain on the surface of the paving stones. The uneven road surface will cause water to accumulate and is difficult to drain quickly, which will affect vehicles and pedestrians.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original paving stones. Summary of the Invention

[0007] The purpose of the present invention is to provide a paving stone for municipal roads to solve the problem raised in the above background technology that traditional paving stones are not convenient to lay and water easily accumulates on the surface of the paving stones.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a paving stone for municipal roads, comprising a paving stone body and a panel disposed therein, wherein a fixing groove is defined within the paving stone body, the edge of the panel is in contact with the inner wall of the fixing groove, and the inner bottom surface of the fixing groove is inclined, overlapping strips are fixed to both sides of the paving stone body, and drainage ports are defined at both ends of the bottom of the paving stone body;

[0009] The panel further comprises a drainage mechanism, which is arranged inside the panel and is used to accelerate the drainage of rainwater on the panel to prevent water accumulation;

[0010] The guiding mechanism is arranged inside the floor paving stone body. The guiding mechanism and the locking mechanism are connected to each other, and the locking mechanism is used to lock two adjacent floor paving stone bodies after they are spliced ​​together.

[0011] Preferably, the guiding mechanism includes an adjusting rod that passes through the inside of the paving stone body, the rotation range of the adjusting rod is 0-90°, and a sleeve plate is fixed on the top of the adjusting rod, and the sleeve plate is hollow inside. At the same time, two connecting plates are symmetrically arranged inside the sleeve plate. The adjusting rod can be rotated through the sleeve plate, and the adjusting rod can drive the connecting plate to rotate.

[0012] Preferably, the connecting plate and the sleeve plate are slidably connected, and the length and width of the sleeve plate are equal to the length and width of the through groove, and the length and width of the connecting plate are equal to the length and width of the connecting groove. At the same time, the through groove and the connecting groove are both opened at the center of the panel. The sleeve plate can pass through the through groove to realize the laying of the panel. After the sleeve plate is rotated, the connecting plate inside it is slid out to make contact with the connecting groove.

[0013] Preferably, a connecting disk is fixed to the bottom of the adjusting rod, and a limiting groove is provided inside the connecting disk, and the limiting groove is an arc-shaped structure. The limiting groove is eccentrically arranged on the connecting disk. At the same time, the inside of the limiting groove is slidably connected to one end of the guide rod, and the other end of the guide rod slides through the floor paving stone body. When the connecting disk rotates, it can be guided by the limiting groove to push the guide rod and the limiting rod to move synchronously.

[0014] Preferably, the locking mechanism includes a limiting rod fixed on the guide rod, and the limiting rod is comb-shaped, and the limiting rod slides through the side of the paving stone body and is connected to the overlapping strip, and the locking mechanism also includes a limiting column fixed to the lower end face of the overlapping strip, and a fixing hole is reserved inside the limiting column. After the limiting rod moves, it passes through the connecting hole and the limiting hole to realize the locking of adjacent paving stones.

[0015] Preferably, a limiting hole is provided on the overlapping strip on the right side of the floor paving stone body, and a connecting hole is provided on the side of the limiting hole, and the central axes of the connecting hole and the fixing hole are on the same horizontal line. At the same time, the limiting columns and the limiting holes are distributed at equal intervals, and the two are connected by snapping. When the two floor paving stones are spliced ​​together, preliminary locking can be achieved by snapping the limiting columns and the limiting holes.

[0016] Preferably, the drainage mechanism includes liquid inlet holes opened on the panel, and the liquid inlet holes are evenly distributed, and the inner diameter of the liquid inlet holes decreases from top to bottom, and a block is provided at the upper end of the inner part of the liquid inlet holes. The accumulated water on the panel can flow to the interior of the floor paving stones through the liquid inlet holes and then be discharged.

[0017] Preferably, the block is a truncated cone structure, and water-swelling waterstop strips are embedded in the side of the block, and the water-swelling waterstop strips are distributed at equal angles. At the same time, the water-swelling waterstop strips are flush with the outer wall of the block. When the water-swelling waterstop strips come into contact with water, they can expand, so that a gap is generated between the block and the liquid inlet hole.

[0018] Preferably, the lower end surface of the block is fixedly connected to one end of the connecting rope, and the other end of the connecting rope is fixed to the inner wall of the liquid inlet hole, and the connecting rope is an elastic rope. When the water stop strip expands when exposed to water, it drives the block position to rise and pulls the connecting rope to extend. Since the connecting rope is elastic, it is convenient to pull the block back to its original position later.

[0019] Compared with the prior art, the present invention has the following advantages: adjacent paving stones for municipal roads can be quickly spliced ​​and locked together without the need for additional concrete bonding, so that the paving stones can be reused after removal, and the aesthetics of the paved surface are improved. At the same time, rainwater on the surface of the paving stones can be quickly drained to prevent water accumulation. The specific contents are as follows:

[0020] 1. Insert the limiting column into the limiting hole to achieve the initial splicing of the two paving stones. After paving is completed, rotate the sleeve 90°, drive the connecting plate to rotate synchronously through the adjusting rod, and then drive the guide rod to slide in the paving stone body through the guidance of the limiting groove. After sliding, push the limiting rod through the connecting hole and the fixing hole to further lock the adjacent paving stone bodies.

[0021] Furthermore, the cover plate can be passed through the through groove before rotation, and overlapped on the connecting groove after rotation, so that the panel and the paving stone body are locked. Then, the connecting plate in the cover plate is slid out, and the integrity of the panel surface is ensured by the cover plate and the connecting plate;

[0022] 2. When rainwater flows to the block, it can contact the water-expanding waterstop strip, causing it to expand. After the expansion, the block rises a certain distance, so that a gap is formed between the block and the liquid inlet hole. The accumulated water on the panel flows through the liquid inlet hole to the fixed groove of the paving stone body and then is discharged. This can prevent water from accumulating on the paving stone body.

[0023] Furthermore, when the rain stops, the surface of the paving stone body is dry, and the water stop strip expands when it comes into contact with water and returns to its original position. The elasticity of the connecting rope pulls the block back to its original position, and the liquid inlet hole is re-sealed, which can prevent a large amount of mud and sand from entering the liquid inlet hole during normal use.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1-12 , the present invention provides the following technical solutions:

[0039] Example 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical solution: a paving stone for municipal roads, including a paving stone body 1 and a panel 7 arranged inside the paving stone body. A fixing groove 5 is provided inside the paving stone body 1, and the edge of the panel 7 is in contact with the inner wall of the fixing groove 5, and the inner bottom surface of the fixing groove 5 is arranged as an inclined surface. Both sides of the paving stone body 1 are fixed with overlapping strips 2, and drainage ports 6 are provided at both ends of the bottom of the paving stone body 1; it also includes: a drainage mechanism, which is arranged inside the panel 7, and the drainage mechanism is used to accelerate the discharge of rainwater on the panel 7 to prevent water accumulation; a guiding mechanism, which is arranged inside the paving stone body 1, and the guiding mechanism and the locking mechanism are connected to each other, and the locking mechanism is used to lock two adjacent paving stone bodies 1 after splicing.

[0040] When laying existing paving stones, adjacent paving stones are bonded with concrete, which is not convenient to splice. It takes a long time for the concrete to dry, which easily causes the adjacent paving stones to shift. In addition, the gaps between the paving stones are of different sizes after laying, which affects the overall aesthetics. At the same time, when the paving stones need to be repaired, a large amount of concrete is adhered to the removed paving stones, which is difficult to clean and affects the subsequent recycling. Figures 1-9As shown, the guiding mechanism includes an adjusting rod 9 that passes through the inside of the paving stone body 1, and the rotation range of the adjusting rod 9 is 0-90°, and a sleeve plate 10 is fixed to the top of the adjusting rod 9, and the sleeve plate 10 is set to be hollow inside, and two connecting plates 11 are symmetrically set inside the sleeve plate 10; the connecting plates 11 and the sleeve plate 10 are slidably connected, and the length and width of the sleeve plate 10 are equal to the length and width of the through groove 12, and the length and width of the connecting plate 11 are equal to the length and width of the connecting groove 13, and the through groove 12 and the connecting groove 13 are both opened at the center of the panel 7; a connecting disk 14 is fixed to the bottom of the adjusting rod 9, and a limiting groove 15 is opened inside the connecting disk 14, and the limiting groove 15 is an arc-shaped structure, and the limiting groove 15 is eccentrically set on the connecting disk 14, and the limiting groove 1 5 is slidably connected to one end of the guide rod 16, and the other end of the guide rod 16 slides through the paving stone body 1; the locking mechanism includes a limiting rod 17 fixed on the guide rod 16, and the limiting rod 17 is comb-shaped, and the limiting rod 17 slides through the side of the paving stone body 1 and is connected to the overlapping strip 2, and the locking mechanism also includes a limiting column 3 fixed to the lower end surface of the overlapping strip 2, and a fixing hole 31 is reserved inside the limiting column 3; a limiting hole 4 is provided on the overlapping strip 2 on the right side of the paving stone body 1, and a connecting hole 41 is provided on the side of the limiting hole 4, and the central axes of the connecting hole 41 and the fixing hole 31 are on the same horizontal line, and the limiting column 3 and the limiting hole 4 are evenly spaced, and the two are snap-connected; Figure 1-Figure 3 As shown, when the paving stone bodies 1 are laid, the overlapping strips 2 on the left side of one paving stone body 1 are connected to the overlapping strips 2 on the right side of the other paving stone body 1, and the limiting columns 3 are inserted into the limiting holes 4 to achieve the initial splicing of the two paving stone bodies 1. The two paving stone bodies 1 are locked by plugging the limiting columns 3 and the limiting holes 4 so that the limiting rods 17 can further lock the limiting columns 3. Figure 5-Figure 6 and Figure 8 As shown, the panel 7 is then laid in the fixed groove 5 in the floor paving body 1. At this time, the cover plate 10 can pass through the through groove 12 on the panel 7. After the laying is completed, the cover plate 10 is rotated 90°, and the connecting plate 14 is driven to rotate synchronously by the adjusting rod 9. When the connecting plate 14 rotates, it is guided by the limit groove 15 so that one end of the guide rod 16 slides in the limit groove 15, and the other end slides in the floor paving body 1. After sliding, the limit rod 17 is pushed through the connecting hole 41 on the side of the limit hole 4 and the fixing hole 31 in the limit column 3, so as to further lock the adjacent floor paving body 1. Figure 7 and Figure 9As shown, the sleeve 10 is rotated and overlapped on the connecting groove 13, so that the panel 7 and the floor paving stone body 1 are locked, and then the connecting plate 11 in the sleeve 10 is slid out to make it contact with the connecting groove 13. At this time, all the paving stone bodies 1 are laid, and the stability of the locking of adjacent floor paving stone bodies 1 is guaranteed, and there is no need to use an additional adhesive structure. When the floor paving stone body 1 is subsequently dismantled, it can also be reused. The panel 7 is laid separately from the floor paving stone body 1. On the one hand, it is to facilitate the locking between adjacent floor paving stone bodies 1 and drive the panel 7 to be locked synchronously, eliminating the labor time of waiting for the concrete to dry to achieve stable splicing. On the other hand, the panel 7 is on the outermost surface of the floor paving stone. It is easily damaged by long-term exposure to the sun and rain, as well as the pressure of vehicles and pedestrians. After damage, only the panel 7 needs to be replaced, and there is no need to replace the entire floor paving stone body 1.

[0041] Example 2: When the existing paving stones are used in rainy days, rainwater will remain on the surface of the paving stones, and the uneven road surface will cause water to accumulate and is difficult to drain quickly, thereby affecting vehicles and pedestrians. Therefore, this embodiment adopts the following technical solutions, such as Figure 4 and Figure 10-12 As shown, the drainage mechanism includes a liquid inlet hole 8 opened on the panel 7, and the liquid inlet holes 8 are evenly distributed, and the inner diameter of the liquid inlet hole 8 decreases from top to bottom, and a block 81 is provided at the upper end of the inner part of the liquid inlet hole 8; the block 81 is a truncated cone structure, and the side of the block 81 is embedded with a water-expanding waterstop 82, and the water-expanding waterstop 82 is distributed at equal angles, and the water-expanding waterstop 82 is flush with the outer wall of the block 81; the lower end face of the block 81 is fixedly connected to one end of a connecting rope 83, and the other end of the connecting rope 83 is fixed to the inner wall of the liquid inlet hole 8, and the connecting rope 83 is an elastic rope; when it rains, rainwater falls on the panel 7 and flows to the position of the block 81, and the rainwater contacts the water-expanding waterstop 82, which can drive it to expand (the water-expanding waterstop 82 is a unique The special new rubber product has the performance of general rubber products and the ability to expand by itself when exposed to water. It is a new type of waterproof material with more reliable water-stopping and waterproofing effects than general rubber. After expansion, it drives the blocking block 81 to rise a certain distance, and drives the connecting rope 83 to extend, so that a gap will be generated between the blocking block 81 and the liquid inlet hole 8. The accumulated water on the panel 7 flows into the fixed groove 5 of the paving stone body 1 through the liquid inlet hole 8, and then is discharged from the drain port 6 along its inclined surface. This can prevent water accumulation on the paving stone body 1 and accelerate the discharge of rainwater. When the rain stops, the surface of the paving stone body 1 is dry, and the water-swelling waterstop strip 82 returns to its original position. The elasticity of the connecting rope 83 pulls the blocking block 81 back to its original position, and the liquid inlet hole 8 is re-sealed. This can prevent a large amount of mud and sand from entering the liquid inlet hole 8 during normal use.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
