Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of curbstone joint processing, in particular to a pavement block joint connection structure. Background Art
[0002] As a typical mineral resource, stone is scarce, environmentally friendly, natural and high-quality. It is a special material for large-scale public construction projects and medium- and high-end buildings around the world. After cutting, grinding, shaping and other processes, stone can be made into various types of paving blocks such as curbstones, roadside stones, and road leveling stones, which are laid on the road to guide the travel of vehicles and people on the road.
[0003] After the pavement stone blocks in the prior art are laid on the pavement, it is usually necessary to perform a grouting treatment on the pavement stones (i.e., the laying blocks), that is, to use cement mortar to fill the gaps between two adjacent pavement stones, thereby reinforcing the connection between the two adjacent pavement stones, preventing wind and rain from invading the gaps, and making the pavement cleaner, neater, and more beautiful. However, due to the narrow and deep gaps between the pavement stones, it is difficult to fill the gaps between the stones with cement mortar. Moreover, during the mortar injection process, the mortar is easy to escape and adhere to the surface of the stone. If it is not cleaned in time, the solidified mortar will remain on the outer surface of the stone, greatly reducing the aesthetics of the pavement. In addition, after the mortar is solidified and formed between two adjacent pavement stones, it will expand and contract due to the influence of temperature. Especially in hot weather, the solidified mortar expands, which easily causes the pavement stones to arch outward, further causing the connection between the stones to loosen and affecting the aesthetics of the pavement.
[0004] Therefore, it is necessary to improve the pavement stone joint connection structure in the prior art. Utility Model Content
[0005] The utility model aims to overcome the defects in the prior art and provide a pavement block joint connection structure which is convenient for construction, ensures aesthetics and avoids loosening of stone connections due to thermal expansion and contraction.

[0034] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0035] First embodiment
[0036] like Figure 1-Figure 4 As shown, the pavement block joint connection structure of the first embodiment of the utility model comprises:
[0037] At least two paving blocks 100, each paving block 100 is paved on the road surface along its length direction and a connecting gap is provided between two adjacent paving blocks 100;
[0038] The sheet component 200 is accommodated in the connection gap, and the two sides of the sheet component 200 are respectively fitted with two adjacent paving blocks 100. The sheet component 200 includes an elastic connection sheet 300 whose thickness direction is consistent with the thickness direction of the connection gap.
[0039] Specifically, in this embodiment, the paving blocks 100 are long strips, and there are three of them. Accordingly, there are two sheet assemblies 200. The paving blocks 100 are curbstones (of course, the paving blocks 100 can also be curbstones, flat stones, and other stones that can be laid on the road surface and used to guide vehicles and people to travel). When the paving blocks 100 are laid on the road surface, the bottom surface fits the road surface, and the front surface faces the center of the road surface; the sheet assembly 200 of two adjacent paving blocks 100 is composed of a single elastic connecting sheet 300, and the connecting sheet 300 is sandwiched between the two adjacent paving blocks 100, so that the two surfaces of the connecting sheet 300 along its own thickness direction are tightly fitted with the end faces of the two adjacent paving blocks 100, and two of the side edges of the circumferential outer edge of the connecting sheet 300 are respectively located on the plane where the bottom surface and the back surface of the paving block 100 are located.
[0040] In the pavement block joint connection structure, the sheet assembly 200 composed of the connecting sheet 300 is clamped between two adjacent paving blocks 100, and the two side surfaces of the circumferential outer edge of the sheet assembly 200 are respectively flush with the back and bottom surfaces of the paving blocks 100 to achieve the grouting effect, thereby preventing wind and rain from invading the connection gap between the two adjacent paving blocks 100. In addition, the connecting sheet 300 is an elastic body that can undergo elastic deformation itself, thereby ensuring that the two surfaces of the connecting sheet 300 along its own thickness direction are respectively flush with the two adjacent paving blocks 100. 00 fits tightly, even if the width of the connection gap between two adjacent paving blocks 100 changes due to thermal expansion and contraction, the connecting sheet 300 can also elastically deform according to the width of the connection gap and adjust its own thickness to be consistent with the width of the connection gap, thereby ensuring that the connecting sheet 300 is tightly clamped between the two paving blocks 100 and avoiding the paving blocks 100 from being squeezed and arched outward after contacting each other, thus solving the problem of jointing during construction and ensuring the overall aesthetics of the pavement block joint connection structure.
[0041] A further improvement is that the sheet assembly 200 and two adjacent paving blocks 100 are enclosed to form a splicing groove 400, and the splicing groove 400 includes a first groove 401 and a second groove 402 that are connected, the groove opening of the first groove 401 is opposite to the plane where the bottom surface of the paving block 100 is located, and the groove opening of the second groove 402 is opposite to the plane where the back surface of the paving block 100 is located; the two ends of the splicing groove 400 extend to the plane where the back surface and the bottom surface of the paving block 100 are located respectively; the groove depth of the splicing groove 400 is 2-3mm.
[0042] Specifically, in this embodiment, after the paving block 100 is laid on the road surface, the bottom and top surfaces of the paving block 100 are parallel to the road surface, the front and back surfaces are perpendicular to the road surface, and the width of the bottom surface is greater than the width of the top surface. The cross-sectional shape of the connecting sheet 300 along its own thickness direction is similar to the cross-sectional shape of the paving block 100, so that the sheet component 200 (that is, a single connecting sheet 300) and the two paving blocks 100 adjacent to the sheet component 200 form a splicing groove 400, which is composed of a first groove 401, a third groove 403 and a second groove 402 that are connected in sequence, wherein the first groove 401 extends in a direction parallel to the road surface, the notch of the first groove 401 faces away from the road surface, and the second groove 402 extends in a direction perpendicular to the road surface. The second groove 402 extends in the same direction, the notch of the second groove 402 is opposite to the plane of the back side of the paving block 100, the third groove 403 extends in the direction inclined to the road surface, the notch of the third groove 403 is opposite to the intersection of the back side and the bottom side of the paving block 100, and the two ends of the splicing groove 400 extend to the plane of the back side of the paving block 100 and the road surface respectively (specifically, the first groove 401 extends to the plane of the back side of the paving block 100, and the second groove 402 extends to the road surface), the groove width of the splicing groove 400 is consistent with the thickness of the connecting sheet 300 and the distance between two adjacent paving blocks 100, and the preferred range is 2-10mm, and the groove depth of the splicing groove 400 is 2-3mm, which ensures the aesthetics of the pavement block joint connection structure.
[0043] It should be noted that, in order to ensure the aesthetics of the pavement block joint connection structure, the depth of the joint groove 400 can also be controlled within 5 mm or less.
[0044] A further improvement is that the connecting sheet 300 is an EVA sheet. EVA is a plastic material, and its chemical name is ethylene-vinyl acetate copolymer. It is a common material widely used in life and is inexpensive. Therefore, the use of EVA sheets can reduce costs. The finished product made of EVA has excellent properties such as good softness, shock resistance, anti-slip, and strong pressure resistance. EVA material has strong softness, chemical corrosion resistance, and good elasticity. To be more specific, EVA sheets are also water-resistant, corrosion-resistant, easy to process, shock-proof and heat-insulating. EVA sheets have a closed cell structure, are non-absorbent, moisture-proof, and have good water resistance. They are resistant to corrosion from seawater, grease, acid, alkali and other chemicals, are antibacterial, non-toxic, odorless, pollution-free, and have no joints. They are also easy to process by hot pressing, cutting, gluing, and bonding. In addition, EVA sheets have high resilience and tensile strength, high toughness, and good shockproof and cushioning properties. Furthermore, EVA sheets also have heat insulation, excellent heat preservation and cold-proof and low-temperature properties, and can withstand severe cold and exposure. Therefore, they are particularly suitable for outdoor use, ensuring the long-term and stable use of the pavement block joint connection structure outdoors.
[0045] A further improvement is that the connecting sheet 300 is fixedly connected to one of the paving blocks 100 ; specifically, the connecting sheet 300 is adhesively connected to the paving block 100 .
[0046] In this embodiment, the connecting sheet 300 and the paving block 100 can be directly connected to the paving block 100 by structural adhesive, so as to realize a quick and fixed connection between the connecting sheet 300 and the paving block 100. During construction, it is only necessary to lay each paving block 100 on the road surface in turn, so that each connecting sheet 300 is clamped and fixed between two adjacent paving blocks 100, thereby avoiding the connection sheet 300 from being separated from between two adjacent paving blocks 100. Of course, the connecting sheet 300 can also be fixedly connected to the paving block 100 by other means.
[0047] A further improvement is that the width of the connecting gap is greater than or equal to 2 mm.
[0048] By controlling the width of the connecting gap, that is, the gap between two adjacent paving blocks 100 to be above 2 mm, it is ensured that there is enough space between two adjacent paving blocks 100, which facilitates the fixed installation of the connecting sheet 300 and facilitates the thermal expansion and contraction of the connecting sheet 300, while ensuring the aesthetics of the pavement block joint connection structure.
[0049] In this embodiment, the paving block 100 is mainly pavement stone. In order to achieve a good pavement decoration effect, the connecting sheet 300 can select a specific color according to the color of the paving block 100. For example, when the paving block 100 is gray, the connecting sheet 300 can be selected to be the same color as the paving block 100, or to select white, black or other colors different from gray, so that the entire pavement block joint connection structure forms a long strip structure of gray and white or gray and black, thereby ensuring the overall aesthetics and decorative effect.
[0050] In order to facilitate laying and alignment, the sheet assembly 200 is flush with the back and bottom of the laying block 100, that is, the connecting sheet 300 is flush with the back and bottom of the laying block 100. Of course, in actual operation, in order to save raw materials and reduce costs, the connecting sheet 300 can also have a gap with the plane where the back and bottom of the laying block 100 are located.
[0051] Second embodiment
[0052] like Figure 5 As shown, the pavement block joint connection structure of the second embodiment is based on the first embodiment, with the difference that the sheet assembly 200 includes at least two connecting sheets 300 distributed along the width direction of the connecting gap, and in the sheet assembly 200, the connecting sheets 300 located at both ends are fixedly connected to two adjacent paving blocks 100 respectively.
[0053] Specifically, the sheet assembly 200 is composed of two connecting sheets 300 of the same structure, and the two connecting sheets 300 are respectively bonded and fixedly connected to the end faces of the two paving blocks 100 to which the sheet assembly 200 is attached. The sheet assembly 200 is composed of two connecting sheets 300, and the two connecting sheets 300 are respectively bonded and fixedly connected to the end faces of the paving blocks 100 before the paving blocks 100 are laid, so as to ensure that the ends of the paving blocks 100 are prevented from being squeezed and collided during transportation, thereby preventing damage, thereby protecting the paving blocks 100.
[0054] Third embodiment
[0055] like Figure 6-Figure 8 As shown, the pavement block joint connection structure of the third embodiment is based on the second embodiment, and the difference is that matching docking protrusions 500 and docking recesses 600 are provided between two adjacent connecting sheets 300 .
[0056] Specifically, between any two adjacent paving blocks 100, two connecting sheets 300 are provided with two docking protrusions 500 and two docking recesses 600. The docking recesses 600 are docking through holes. When paving the paving blocks 100, in the two adjacent paving blocks 100, the docking protrusions 500 between the two connecting sheets 300 in the sheet assembly 200 are inserted into the docking recesses 600, so that the two adjacent paving blocks 100 can be accurately docked, thereby avoiding position deviation when the paving blocks 100 are laid on the road surface.
[0057] Fourth embodiment
[0058] like Fig. 9 and Fig.10 As shown, the pavement block joint connection structure of the fourth embodiment is based on the third embodiment, and the difference is that the connecting sheet 300 is provided with a material reduction hole 700.
[0059] Specifically, the material reduction hole 700 is a circular through hole and a plurality of material reduction holes 700 are provided. After the material reduction holes 700 are provided on the connection sheet 300, the amount of production materials of the connection sheet 300 can be reduced, thereby reducing the production cost. Moreover, after each laying block 100 is laid, a cavity can be formed at the material reduction hole 700 of the connection sheet 300, so that after the connection sheet 300 is deformed by thermal expansion and contraction and extrusion, the cavity formed by the material reduction hole 700 is deformed, making the connection sheet 300 easier to deform.
[0060] Fifth embodiment
[0061] like Fig.11 and Fig.12As shown, the pavement block joint connection structure of the fifth embodiment is based on the fourth embodiment, and the difference is that the connection sheet 300 is a long strip structure.
[0062] Compared with the fourth embodiment, the connecting sheet 300 of this embodiment is a long strip-shaped structure. Specifically, it is cut into a strip sheet structure with a shape matching the outer shape of the paving block 100, so that two adjacent paving blocks 100 and the connecting sheet 300 therebetween enclose a splicing groove 400, and the two ends of the splicing groove 400 extend to the plane where the back surface and the bottom surface of the paving block 100 are located, respectively. In this way, without affecting the overall outer tube of the pavement block joint connection structure, the amount of production materials of the connecting sheet 300 can be further reduced, thereby reducing production costs, and there is more space between two adjacent paving blocks 100 and the connecting sheet 300, which facilitates the deformation of the connecting sheet 300 due to cold expansion and contraction and extrusion, thereby avoiding the paving block 100 from arching outward.
[0063] In order to facilitate laying, the connecting sheet 300 can be pre-bonded to the end surface of one of the laying blocks 100 .
[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
