Description

Technical Field

[0001] The present invention relates to the technical field of pedestrian paving bricks, and particularly to a highly efficient and durable paving brick. Background Art

[0002] As is well known, currently on urban sidewalks, in order to facilitate pedestrian passage and beautify the city appearance, paving bricks are usually laid. The existing pedestrian road paving bricks are usually solid square bricks with a small area. Therefore, during the paving process, first the roadbed of the ground is compacted, and then a cushion layer is laid, usually using crushed stones or lime soil. After laying a mortar bonding layer, the solid square bricks can be laid. Only in this way can it be ensured that the laid solid square bricks maintain the same height, and the overall road surface remains flat and stable, preventing the road surface from being uneven due to the influence of environmental temperature, humidity and other factors. When laying the square bricks, it is necessary to manually use a rubber hammer to tamp them, which is very time-consuming and laborious. After tamping, it is also necessary to fill the gaps between the square bricks, which is also time-consuming and laborious; the existing construction plan usually adopts the above steps to ensure the stability and flatness of the road surface. However, from the start of construction to completion, the required construction period is very long, the steps are relatively cumbersome, and the construction operations are greatly affected by weather changes. For example, in case of rain or snow during the laying of the cushion layer, the laying quality will be seriously affected, and the project cost is high; the existing concrete paving bricks are usually cast and made outdoors on site. During the actual construction process, the influence factors of the environment are relatively large, such as temperature, humidity and other factors. Therefore, it is impossible to ensure the best state of the concrete material. Under unfavorable environmental conditions, the pouring quality of the paving bricks will be seriously affected; currently, there is still no effective solution to this problem in this industry, and when the solid square bricks are laid in areas with relatively low temperatures, it is easy to occur that the cement slurry is difficult to solidify and the laid road surface cracks, etc., and additional heat preservation measures need to be added, further increasing the construction cost. Summary of the Invention

[0003] (1) Technical Problems to be Solved

[0005] (2) Technical Solutions

[0006] To achieve the above object, the present invention provides the following technical solution: A highly efficient and durable road brick, characterized in that it includes a top surface, a bottom surface and a side surface. The top surface, the bottom surface and the side surface constitute the external structure of the road brick, and a cavity structure is formed inside. A plurality of support columns are arranged in the cavity. The plurality of support columns connect and support the top surface and the bottom surface. Support blocks are provided at the connection parts of the top of the plurality of support columns with the top surface and the connection parts of the bottom with the bottom surface. The top surface, the bottom surface, the side surface and the plurality of support columns are integrally cast in concrete. The remaining part of the cavity is provided with a filler, and the filler serves as a part of the mold for casting and molding; steel wire meshes are filled and arranged in both the top surface and the bottom surface; the plurality of support columns are arranged in a staggered manner both horizontally and vertically between the top surface and the bottom surface, and the plurality of support columns together form a honeycomb structure.

[0007] Preferably, the filler is a lightweight water-repellent material, such as polystyrene board, polyurethane foam board, etc. The filler serves as a mold in the process of prefabricating and casting the road brick body, and remains in the cavity structure after the road brick body is cast and molded.

[0008] Preferably, the plurality of support columns are evenly distributed in the cavity.

[0009] Preferably, the support block and the support column are integrally cast and molded. The diameter of the end of the support block away from the support column is larger than the diameter of the end of the support block close to the support column.

[0010] (III) Beneficial effects

[0011] Compared with the prior art, the present invention provides an efficient and durable paving brick, which has the following beneficial effects: The present invention prefabricates square paving bricks by means of integral concrete pouring. The interior of this square paving brick is not solid concrete, but a plurality of groups of concrete support columns are used to connect the bottom surface and the top surface, so as to support and disperse stress on the top surface. The rest of the middle part is a filler. The filler serves as a mold during the pouring of the paving brick. After pouring and forming, it occupies the space between the top surface and the bottom surface of the paving brick to support the paving brick. While ensuring the overall stability of the paving brick, it is lighter in weight and saves production costs. The plurality of groups of support columns are staggered both horizontally and vertically between the top surface and the bottom surface, and the overall structure is in a honeycomb structure. The honeycomb structure form can reduce the material usage while dispersing the load through geometric shapes, significantly improving the specific strength of the overall structure. The synergistic effect of each unit enables the structure to withstand multi-directional loads, evenly disperse stress, reduce local stress concentration, and avoid structural instability. When the paving brick is used for a long time or the top surface of the paving brick is fractured and damaged due to external forces, the honeycomb distribution structure can effectively block the extension of the crack, making the overall structural integrity of the paving brick higher and not easily causing large-area fractures. When a part of the paving brick is damaged, through the honeycomb distribution structure of the plurality of groups of support columns, the spread of the damaged part is effectively blocked, reducing losses and facilitating subsequent repair, and reducing the repair cost; The steel mesh is preset in the pouring mold and is embedded in the interior of the top surface and the bottom surface after pouring to improve the compressive strength of the top surface and the bottom surface. The filler is a lightweight water-repellent material, such as polystyrene board, polyurethane foam material, etc. As a mold for the prefabrication and pouring process of the paving brick body, after the paving brick body is poured and formed, it remains and occupies the cavity structure to support the top surface of the paving brick. The lightweight water-repellent material has good water-repellent performance, which can effectively reduce the moisture content of the overall paving brick. When applied in cold regions, it can prevent the frost heaving phenomenon caused by the freezing of water, thereby protecting the material structure of the paving brick from frost heaving damage. The support blocks on the plurality of groups of support columns can further optimize the support structure inside the paving brick, improve the support effect of the support columns, thereby improving the compressive performance of the top surface and extending the service life of the paving brick. The paving brick of the present invention has a large area and a stable structure, and there is no need to lay a cushion layer and a bonding layer on the roadbed, and it can be directly laid on the roadbed. Compared with the paving method of splicing and combining a plurality of small-area square bricks, the integration degree is high, and it is not easy to appear uneven road surface; Due to the lightweight structure, paving bricks with a relatively large area can be made, and the paving of the road surface can be completed relatively quickly. The gaps between the square bricks are small, the construction difficulty is low, the construction period is short, the on-site construction area is small, the prefabrication precision of the size is high, the construction quality can be guaranteed, and the engineering cost is low by using economies of scale. It is easy to achieve and maintain a clean and orderly modern civilized construction at the construction site;

[0012] The paving bricks of this application are integrally precast and cast, and the precast environment is inside a factory workshop. The advantage is that the environmental factors inside the workshop can be adjusted adaptively, such as temperature, humidity, etc., so that the material properties of the concrete reach the optimal, thereby ensuring the casting quality of the paving bricks and extending the service life; avoiding quality defects of the paving bricks caused by the influence of environmental factors during casting at the construction site.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-6, the present invention provides a technical solution: a highly efficient and durable paving brick, which is characterized in that it includes a top surface 1, a bottom surface 2 and a side surface 3. The top surface 1, the bottom surface 2 and the side surface 3 constitute the external structure of the paving brick, and a cavity structure is formed inside. A plurality of support columns 4 are arranged in the cavity. The plurality of support columns 4 connect and support the top surface 1 and the bottom surface 2. Support blocks 5 are arranged at the connection parts of the top of the plurality of support columns 4 with the top surface 1 and the connection parts of the bottom with the bottom surface 2. The top surface 1, the bottom surface 2, the side surface 3 and the plurality of support columns 4 are of an integrally cast concrete structure. The remaining part in the cavity is provided with a filler 6, and the filler 6 serves as a part of the casting mold; Reinforcement meshes 7 are filled in both the top surface 1 and the bottom surface 2; The plurality of support columns 4 are arranged in a staggered manner both horizontally and vertically between the top surface 1 and the bottom surface 2, and the plurality of support columns 4 together form a honeycomb structure.

[0022] Specifically, place the steel mesh 7 and the filler 6 in the concrete casting mold. The filler 6 is located between two sets of steel meshes 7. Cast the concrete in the paving brick mold for shaping. Both the filler 6 and the steel mesh 7 are covered by the concrete. Since the filler 6 is located inside the paving brick and the paving brick is not made of solid concrete, it is lighter in weight and square bricks with a relatively large area can be made. The prefabrication process of the paving brick is carried out entirely in the factory workshop. The advantage is that the environmental factors in the workshop, such as temperature and humidity, can be adjusted adaptively to meet the material performance requirements of the concrete, making its material performance reach the optimum, thus ensuring the casting and shaping quality of the paving brick and extending its service life. It avoids quality defects of the paving brick caused by environmental factors during casting at the construction site. When laying at the construction site, only need to tamp and level the roadbed, and then directly lay this prefabricated square brick. Because of its large area and simple construction steps, the rapid laying work can be completed. The top surface 1 is stably supported by multiple sets of support columns 4 and support blocks 5 to disperse stress. The compressive performance of the top surface 1 and the bottom surface 2 is improved by the steel mesh 7, thus improving the bearing capacity of the top surface 1 of the paving brick. The filler is a lightweight water-repellent material, such as polystyrene board, polyurethane foam material, etc. The lightweight water-repellent material has good water-repellent performance and can effectively reduce the overall moisture content of the paving brick. Applied in cold regions, it can prevent frost heaving caused by water freezing, thus ensuring that the material structure of the paving brick is not damaged by frost heaving. The filler 6 has heat preservation performance and can keep the roadbed warm to prevent it from cracking due to low temperature. There is no need to lay a heat preservation layer and a cushion layer separately, so the laying cost is saved and the construction period is greatly shortened. Compared with the laying method of splicing and combining multiple sets of small-area square bricks, the integration degree is high. The filler 6 serves as a mold during the casting of the paving brick and occupies the space between the top surface 1 and the bottom surface 2 of the paving brick after casting and shaping, supporting the paving brick. While ensuring the overall stability of the paving brick, it is lighter and saves production costs. Multiple sets of support columns 4 are staggered horizontally and vertically between the top surface 1 and the bottom surface 2, presenting an overall honeycomb structure. The honeycomb structure form can reduce the material usage while dispersing the load through the geometric shape, significantly improving the specific strength of the overall structure. The synergistic effect of each unit enables the structure to withstand multi-directional loads, evenly disperse stress, reduce local stress concentration, and avoid structural instability. When the paving brick is used for a long time or the top surface of the paving brick is fractured and damaged due to external forces, the honeycomb distribution structure can effectively block the extension of the crack, making the overall structure integration degree of the paving brick higher and not easily causing large-area fracture. When a part of the paving brick is damaged, the honeycomb distribution structure of multiple sets of support columns effectively blocks the spread of the damaged part, reducing the loss and also facilitating its subsequent repair, reducing the repair cost;Due to its lightweight structure, it is possible to produce relatively large-area paving bricks, enabling the paving of the road surface to be completed quickly. The gaps between the square bricks are small, the construction difficulty is low, the construction period is short, the working area on-site is small, the prefabrication precision of the dimensions is high, the construction quality can be guaranteed, and economies of scale are utilized, resulting in low project costs. It is easy to achieve and maintain a clean and orderly modern civilized construction site.

[0023] In the present invention, the filler is a lightweight water-repellent material, such as polystyrene board, polyurethane foam board, etc. The filler serves as a mold during the prefabricated casting process of the paving brick body, and after the paving brick body is cast and formed, it remains in the cavity structure.

[0024] Specifically, as a casting mold, the lightweight water-repellent material has the properties of light weight, water repellency, and heat insulation. After casting, it can be directly embedded in the cavity structure formed by the top surface 1 and the bottom surface 2 of the paving brick without being removed. The lightweight water-repellent material filler 6 provides support for the top surface 1, and due to the good water-repellent performance of the lightweight water-repellent material, it can reduce the overall moisture content of the paving brick, and when applied in cold regions, it can prevent the frost heaving phenomenon caused by the freezing of water, thereby protecting the material structure of the paving brick from frost heaving damage.

[0025] In the present invention, the multiple groups of support columns 4 are evenly distributed from within the cavity.

[0026] Specifically, the multiple groups of support columns 4 are evenly arranged in an array, staggered horizontally and vertically respectively, and the overall forms a honeycomb structure, effectively and evenly dispersing stress, reducing local stress concentration, and avoiding structural instability.

[0027] In the present invention, the support block 5 and the support column 4 are of an integrally cast structure, and the diameter of the end of the support block 5 far from the support column 4 is larger than the diameter of the end of the support block 5 close to the support column 4.

[0028] Specifically, the support block 5 serves as a strengthening structure for the support column 4, which can further increase the contact area between the support column 4 and the top surface 1 and the bottom surface 2, thereby enhancing the bearing capacity of the top surface 1 and the bottom surface 2 and improving the compressive performance of the paving brick.

[0029] When the present invention is in use, the steel mesh 7 and the filler 6 are placed in a concrete casting mold, with the filler 6 located between two groups of steel meshes 7. Concrete is poured into the pavement brick mold for forming. Both the filler 6 and the steel mesh 7 are covered by the concrete. Since the filler 6 is located inside the pavement brick and the pavement brick is not made of solid concrete, it is lighter in weight and square bricks with a relatively large area can be produced. The prefabrication process of the pavement brick is carried out entirely in the factory workshop. The advantage is that the environmental factors in the workshop, such as temperature, humidity, etc., can be adjusted adaptively to meet the material performance requirements of the concrete, making its material performance reach the optimum, thus ensuring the casting and forming quality of the pavement brick and extending its service life. It avoids quality defects of the pavement brick caused by environmental factors during casting at the construction site. When laying at the construction site, only the roadbed needs to be tamped and leveled, and then this prefabricated square brick can be directly laid. Because of its large area and simple construction steps, the rapid laying work can be completed. The top surface 1 is stably supported by multiple groups of support columns 4 and support blocks 5 to disperse stress. The compressive performance of the top surface 1 and the bottom surface 2 is improved by the steel mesh 7, thereby enhancing the bearing capacity of the top surface 1 of the pavement brick. The filler 6 has heat preservation performance and can heat-preserve the roadbed to prevent it from cracking due to low temperature. There is no need to lay a heat preservation layer and a cushion layer separately, so the laying cost is saved and the construction period is greatly shortened. Compared with the laying method of splicing and combining multiple groups of small-area square bricks, the integration degree is high. The filler 6 serves as a mold during the casting of the pavement brick and occupies the space between the top surface 1 and the bottom surface 2 of the pavement brick after casting and forming, supporting the pavement brick. While ensuring the overall stability of the pavement brick, it is lighter and saves production costs. The filler is a lightweight water-repellent material, such as polystyrene board, polyurethane foam board, etc., which has good water-repellent performance and can effectively reduce the overall water content of the pavement brick. When applied in cold regions, it can prevent the frost heaving phenomenon caused by the freezing of water, thus protecting the material structure of the pavement brick from frost heaving damage. Multiple groups of support columns 4 are staggered both horizontally and vertically between the top surface 1 and the bottom surface 2, and the overall structure is in a honeycomb shape. The honeycomb structure can reduce the material consumption while dispersing the load through its geometric shape, significantly enhancing the specific strength of the overall structure. The synergistic effect of each unit enables the structure to withstand multi-directional loads, evenly disperse stress, reduce local stress concentration, and avoid structural instability. When the pavement brick is used for a long time or the top surface of the pavement brick is fractured and damaged due to external forces, the honeycomb distribution structure can effectively block the extension of the crack, making the overall structure integration degree of the pavement brick higher and not easily prone to large-area fracture. When a local part of the pavement brick is damaged, the honeycomb distribution structure of multiple groups of support columns can effectively block the spread of the damaged part, reduce the loss, and also facilitate its subsequent repair, reducing the repair cost.Due to the lightweight structure, it is possible to produce pavement bricks with a relatively large area, complete the paving of the road surface relatively quickly, and the gaps between the square bricks are small, the construction difficulty is low, the construction period is short, the working area for on-site construction is small, the prefabrication precision of the size is high, the construction quality can be guaranteed, economies of scale are utilized, the project cost is low, and it is easy to achieve and maintain a clean and orderly modern civilized construction site.
