Description

Technical Field

[0001] This utility model relates to the field of curbstone technology, and in particular to a high-quality, transparent, horizontal curbstone. Background Technology

[0002] Curbstones, also known as kerb stones, are strip-shaped structures placed along the edge of a road to define road boundaries, protect the road structure, guide traffic flow, and assist in drainage. Common curbstone materials include cement concrete and natural stone, and they can be categorized by function and appearance into flat curbstones, upright curbstones, and beveled curbstones.

[0003] High-grade permeable natural sand curbstone is a new type of curbstone. It uses natural sand of quartz or granite texture as the main aggregate, combined with auxiliary aggregates such as waste ceramic particles, and adds various functional additives. It employs a double-layer structure design: the outer layer is aesthetically pleasing and permeable, while the bottom layer provides strength support. The overall porosity is controlled at 15%-25%, achieving highly efficient permeability. Combining durability with aesthetics and environmental friendliness, it effectively reduces road surface water accumulation, meets the needs of use in complex environments, and has significant application value and promising prospects in urban road construction.

[0004] When high-quality permeable sandstone curb stones are installed along the roadside, multiple stones need to be arranged in a row. Adjacent stones are fixed together by pouring cement mortar. However, with wind and rain, the cement mortar is prone to cracking, causing the connection between the stones to loosen and reducing the stability of the connection. In addition, the top edge of the high-quality permeable sandstone curb stones lacks impact-resistant cushioning, and is often prone to chipping due to accidental bumps, affecting the aesthetics. Therefore, in view of the above situation, there is an urgent need to develop a high-quality permeable sandstone curb stone that is stably connected and has good impact-resistant performance to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] The purpose of this invention is to provide a high-quality translucent horizontal edge stone to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-grade permeable granite curbstone includes a surface layer, a base layer, a shock-absorbing strip, an anti-freeze layer, and connecting rods. The surface layer is fixed to the outside of the base layer. The surface layer is composed of modified epoxy resin and granite particles. After shrinkage and solidification, the modified epoxy resin maintains very fine pores, allowing water to flow through them, thus giving the surface layer excellent permeability. The top of the surface layer has an arched dome, higher in the middle and lower on both sides, so that water flowing from the top of the surface layer slides to the sides, reducing water accumulation. The base layer is made of cast concrete. An antifreeze layer made of foamed concrete is fixed to the bottom of the base layer. The base layer has multiple first permeable holes, and the antifreeze layer has multiple second permeable holes. The first and second permeable holes are aligned. An anti-collision buffer strip made of EVA foam is fixed to each of the two top sides of the fabric layer. EVA foam has good elastic cushioning performance. Two elastic baffles made of spring steel are fixed to both ends of the connecting rod. The base layer has slots for inserting the connecting rod at both ends.

[0008] Preferably, the bottom of the base layer is provided with a trapezoidal base, which increases the contact area between the base layer 2 and the ground to improve the stability of the installation.

[0009] Preferably, the length of the connecting rod is more than 5 mm longer than twice the depth of the slot. When the connecting rod connects two base layers, after the connecting rod is fully inserted into each of the two base layers, there is still a 5 mm gap between the two base layers. This gap is used to pour cement mortar so that the connection between the two base layers is more stable.

[0010] Preferably, the slot includes an inlet slot and a locking slot. The inlet slot has a chamfer at its entrance, and the locking slot is wider than the inlet slot. When the connecting rod is inserted into the inlet slot, the elastic baffle is first compressed. After the elastic baffle is fully inserted into the locking slot, it expands outward by its own elasticity, locking itself into the locking slot, thereby making the connecting rod stably connected to the base layer.

[0011] Preferably, the width of the inlet groove is 6-8 mm larger than the width of the connecting rod.

[0012] Preferably, the anti-collision buffer strip has a honeycomb structure. The hollow structure of the honeycomb and the buffer material can effectively absorb impact energy. When subjected to external impact, it can effectively absorb the impact force and improve the protective performance.

[0013] Preferably, the outer surfaces of the connecting rod and the elastic baffle are coated with anti-rust paint.

[0014] The beneficial effects of this utility model are as follows: When using this high-quality natural sand-permeable horizontal curbstone, first, a foundation pit is dug in the ground, then the trapezoidal base and anti-freeze layer are buried in the pit. The trapezoidal base increases the contact area between the base layer and the ground, making it more stable. Then, two adjacent base layers are connected with a connecting rod. When the connecting rod is inserted into the inlet groove, the elastic baffle is first compressed. After the elastic baffle is fully inserted into the locking groove, it expands outwards by its own elasticity, locking itself into the locking groove, thus stably connecting the connecting rod and the base layer together. This operation connects multiple base layers together. Finally, cement mortar is poured into the gap between two adjacent base layers to further stabilize the connection between them. When it rains, rainwater passes through the micropores in the fabric layer and then seeps downwards into the ground through the first and second permeable holes for rapid drainage. The arched top, higher in the middle and lower on both sides, allows water to slide off the top of the fabric layer, further improving drainage performance. The anti-freeze layer is made of foamed concrete, which is lightweight and has thermal insulation properties, reducing heat transfer and mitigating the impact of freeze-thaw cycles on the base layer. The impact-resistant buffer strip is made of EVA foam, which has excellent elastic cushioning properties. The buffer strip has a honeycomb structure; the hollow structure and cushioning material effectively absorb impact energy, enhancing protective performance when subjected to external impacts. In summary, this invention features stable interconnections, good water permeability and drainage, and excellent impact resistance and anti-freeze properties. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] See Figures 1-7In this embodiment of the invention, a high-grade permeable granite curbstone includes a surface layer 1, a base layer 2, an anti-collision buffer strip 3, an anti-freeze layer 4, and a connecting rod 5. The surface layer 1 is fixed to the outside of the base layer 2. The surface layer 1 is composed of modified epoxy resin and granite particles. After shrinkage and solidification, the modified epoxy resin can maintain very fine pores, allowing water to flow through these pores, thus giving the surface layer 1 good permeability. The base layer 2 is made of cast concrete to provide good support for the surface layer 1. A trapezoidal base 201 is provided at the bottom of the base layer 2. The trapezoidal base 201 increases the contact area between the base layer 2 and the ground to improve installation stability. An anti-freeze layer 4, made of foamed concrete, is fixed to the bottom of the base layer 2. Foamed concrete is lightweight and has thermal insulation properties, reducing heat transfer and mitigating the impact of freeze-thaw cycles on the curb. Its numerous closed pores buffer frost heave pressure. During installation, a pit is first dug in the ground, and the trapezoidal base 201 and the anti-freeze layer 4 are buried in the pit. The base layer 2 has multiple first permeable holes 203, and the anti-freeze layer 4 has multiple second permeable holes 401. The first water-permeable hole 203 is aligned with the second water-permeable hole 401 to allow water to flow downwards. A shock-absorbing strip 3 is fixed to each of the two top sides of the fabric layer 1. The shock-absorbing strip 3 is made of EVA foam, which has good elastic cushioning performance. The shock-absorbing strip 3 has a honeycomb structure 301 inside. The hollow structure and cushioning material of the honeycomb structure 301 can effectively absorb impact energy. When subjected to external impact, it can effectively absorb the impact force, improving the protective performance. Two elastic baffles 501 are fixed to both ends of the connecting rod 5. 501 is made of spring steel, giving it good elasticity. The outer surfaces of the connecting rod 5 and the elastic baffle 501 are coated with anti-rust paint, giving it good anti-rust performance. Both ends of the base layer 2 are provided with slots 202 for inserting the connecting rod 5. The length of the connecting rod 5 is more than twice the depth of the slot 202 by 5 mm. When the connecting rod 5 connects the two base layers 2, after the connecting rod 5 is fully inserted into the two base layers 2, there is still a 5 mm gap between the two base layers 2. This gap is used to pour cement mortar so that the connection between the two base layers 2 is more stable.

[0027] The slot 202 includes an inlet slot 2021 and a locking slot 2022. The inlet slot 2021 has a chamfer at the entrance to allow the connecting rod 5 to be inserted. The width of the locking slot 2022 is greater than the width of the inlet slot 2021. The width of the inlet slot 2021 is 6-8 mm larger than the width of the connecting rod 5. When the connecting rod 5 is inserted into the inlet slot 2021, the elastic baffle 501 is first compressed. After the elastic baffle 501 is fully inserted into the locking slot 2022, the elastic baffle 501 expands outward by its own elasticity, locking itself into the locking slot 2022, thereby making the connecting rod 5 stably connected to the base layer 2.

[0028] The top of the fabric layer 1 is provided with an arc-shaped top 101, which is higher in the middle and lower on both sides, so that the water flow at the top of the fabric layer 1 can slide to both sides and reduce the accumulation of water flow.

[0029] Working Principle: This high-quality permeable horizontal curbstone is used by first digging a pit in the ground, then burying the trapezoidal base 201 and the anti-freeze layer 4 inside the pit. The trapezoidal base 201 increases the contact area between the base layer 2 and the ground, making it more stable. Next, two adjacent base layers 2 are connected by a connecting rod 5. When the connecting rod 5 is inserted into the inlet groove 2021, the elastic baffle 501 is first compressed. After the elastic baffle 501 is fully inserted into the clamping groove 2022, it expands outwards due to its own elasticity, locking into the clamping groove 2022, thus stably connecting the connecting rod 5 to the base layer 2. This process connects multiple base layers 2 together. Finally, cement mortar is poured into the gap between two adjacent base layers 2 to ensure the two base layers 2... The connection is more stable. When it rains, rainwater passes through the micropores on the fabric layer 1 and then seeps downwards into the ground through the first permeable hole 203 and the second permeable hole 401 for rapid drainage. The arc-shaped top 101 is higher in the middle and lower on both sides, so that the water at the top of the fabric layer 1 slides to both sides, further improving drainage performance. The anti-freeze layer 4 is made of foamed concrete. Foamed concrete has lightweight and heat insulation properties, which can reduce heat transfer and reduce the impact of freeze-thaw cycles on the base layer 2. The anti-collision buffer strip 3 is made of EVA foam. EVA foam has good elastic buffer performance. The anti-collision buffer strip 3 has a honeycomb structure 301. The hollow structure of the honeycomb structure 301 and the buffer material can effectively absorb impact energy. When subjected to external impact, it can effectively absorb the impact force and improve the protective performance.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
