Description

Technical Field

[0001] This utility model relates to the technical field of pedestrian pavement bricks, and in particular to a high-efficiency and durable pavement brick. Background Technology

[0002] As is well known, paving bricks are commonly used on urban sidewalks to facilitate pedestrian traffic and beautify the cityscape. Existing sidewalk paving bricks are typically solid square bricks with a small area. Therefore, during the paving process, the subgrade is first compacted, followed by a subbase layer, usually made of crushed stone or lime-soil, and then a mortar bonding layer. Only then can the solid square bricks be laid. This ensures that all the solid square bricks are laid at the same height, maintaining a flat and stable overall surface and preventing unevenness caused by environmental factors such as temperature and humidity. When laying the bricks, manual compaction with a rubber mallet is required, a very time-consuming and labor-intensive process. After compaction, the gaps between the bricks need to be filled, another time-consuming and labor-intensive task. Existing construction methods typically employ these steps to ensure... The stability and smoothness of the road surface are crucial; however, the construction period from start to finish is long and the steps are complex. Construction is greatly affected by weather changes; for example, rain or snow during the laying of the subbase can severely impact the paving quality and increase project costs. Existing concrete paving bricks are typically poured and manufactured in the open air on-site. In actual construction, environmental factors such as temperature and humidity have a significant impact, making it impossible to guarantee the optimal state of the concrete materials. Under unfavorable environmental conditions, the pouring quality of the paving bricks will be severely affected. Currently, there is no effective solution to this problem in the industry. Furthermore, when solid bricks are laid in low-temperature areas, cement slurry is prone to failure to cure, and the paved surface may crack, requiring additional insulation measures, further increasing construction costs. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency and durable paving brick that features a short construction cycle, rapid road surface paving, improved road stability and smoothness, good durability, resistance to harsh environments, factory manufacturing to ensure casting quality, relatively low project costs, frost heave resistance, extended service life, minimal environmental impact, wide application scenarios, and meets the needs of modern civilized construction.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and durable paving brick, characterized in that it includes a top surface, a bottom surface, and side surfaces, which constitute the external structure of the paving brick and form an internal cavity structure. Multiple sets of support columns are arranged within the cavity, connecting and supporting the top and bottom surfaces. Support blocks are provided at the top and bottom connections of the support columns. The top surface, bottom surface, side surfaces, and support columns are integrally cast concrete structures. The remaining portion of the cavity is filled with a filling material, which serves as a mold for casting. Reinforcing mesh is filled into both the top and bottom surfaces. The multiple sets of support columns are arranged in a staggered pattern both horizontally and vertically between the top and bottom surfaces, collectively forming a honeycomb structure.

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

[0008] In a preferred embodiment of this invention, the multiple sets of support columns are evenly distributed within the cavity.

[0009] In a preferred embodiment of this invention, the support block and the support column are integrally cast and molded, with the diameter of the end of the support block furthest from the support column being larger than the diameter of the end of the support block closest to the support column.

[0010] (III) Beneficial Effects

[0011] Compared with existing technologies, this utility model provides a high-efficiency and durable paving brick with the following advantages: This utility model uses a precast square paving brick made by integral concrete casting. The interior of this square paving brick is not solid concrete, but rather uses multiple sets of concrete support columns and support blocks to connect the bottom and top surfaces, supporting the top surface and dispersing stress. The remaining part in the middle is filled material, which serves as a mold during the casting process. After casting, it occupies the space between the top and bottom surfaces of the paving brick, providing support. This ensures the overall stability of the paving brick while making it lighter and saving production costs. The multiple sets of support columns are distributed horizontally and vertically between the top and bottom surfaces, forming an overall honeycomb structure. The honeycomb structure can significantly improve the overall structural strength by dispersing loads through geometric shape while reducing material usage. The synergistic effect of each unit enables the structure to withstand multi-directional loads, uniformly distribute stress, reduce local stress concentration, and prevent structural instability. When paving bricks are used for a long time or when the top surface of the paving bricks is damaged by external forces, the honeycomb distribution structure can effectively prevent the extension of cracks, making the overall structural integrity of the paving bricks higher and less prone to large-area fractures. When paving bricks are damaged locally, the honeycomb distribution structure of multiple sets of support columns effectively prevents the spread of damage, reduces losses, and facilitates subsequent repairs, reducing repair costs. (Reinforcing steel) The mesh is pre-installed in the casting mold and embedded inside the top and bottom surfaces after casting, improving the compressive strength of the top and bottom surfaces. The filler is a lightweight water-repellent material, such as polystyrene board or polyurethane foam. It serves as the mold for the precast casting process of the paving brick body. After casting, the paving brick body remains and occupies the cavity structure, supporting the top surface of the paving brick. The lightweight water-repellent material has excellent water-repellent properties, effectively reducing the overall moisture content of the paving brick. In cold regions, it prevents frost heave caused by water freezing, thus protecting the material structure of the paving brick from frost damage. The support blocks on multiple sets of support columns further optimize the internal support structure of the paving brick, improving the support effect of the support columns. This invention improves the compressive strength of the top surface and extends the service life of the paving bricks. The paving bricks of this invention have a larger area and a stable structure. They do not require a subbase or bonding layer on the roadbed and can be laid directly on the roadbed. Compared with the method of splicing and combining multiple sets of smaller square bricks, the integration is high and the unevenness of the road surface is less likely to occur. Due to the lightweight structure, relatively large paving bricks can be produced, and the road surface can be laid 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 dimensional prefabrication accuracy is high, the construction quality can be guaranteed, the 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.

[0012] The paving bricks of this application are precast and cast in a factory workshop. The advantage of this method is that the environmental factors in the workshop, such as temperature and humidity, can be adjusted according to the needs of the workers, so that the material properties of the concrete can be optimized, thereby ensuring the casting quality of the paving bricks and extending their service life. This avoids the quality defects of the paving bricks caused by environmental factors when casting on the construction site. Attached Figure Description

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6This utility model provides a technical solution: a high-efficiency and durable paving brick, characterized in that it includes a top surface 1, a bottom surface 2, and side surfaces 3, which constitute the external structure of the paving brick and form an internal cavity structure. Multiple sets of support columns 4 are arranged within the cavity, connecting and supporting the top surface 1 and the bottom surface 2. Support blocks 5 are provided at the connection points between the top and top surface 1 and the bottom and bottom surfaces 2 of the multiple sets of support columns 4. The top surface 1, bottom surface 2, side surfaces 3, and multiple sets of support columns 4 are integrally cast concrete structures. The remaining portion of the cavity is filled with a filler 6, which serves as a mold for casting. Steel mesh 7 is filled into both the top surface 1 and the bottom surface 2. The multiple sets of support columns 4 are arranged alternately horizontally and vertically between the top surface 1 and the bottom surface 2, forming a honeycomb structure.

[0022] Specifically, the reinforcing mesh 7 and the filler 6 are placed inside the concrete casting mold, with the filler 6 positioned between two sets of reinforcing mesh 7. Concrete is then poured into the paving brick mold for shaping. Both the filler 6 and the reinforcing mesh 7 are encased in concrete. Because the filler 6 is located inside the paving brick, and the paving brick is not solid concrete, it is relatively lightweight, allowing for the production of relatively large square bricks. The entire prefabrication process for paving bricks is carried out in the factory workshop. This has the advantage of allowing for adaptive adjustments to environmental factors within the workshop, such as temperature and humidity, to meet the material performance requirements of the concrete, optimizing its material properties and thus ensuring the quality of the paving brick casting and extending its service life. This avoids the need for on-site adjustments. Environmental factors during the pouring process can lead to quality defects in the paving bricks. When laying them on-site, only the roadbed needs to be compacted and leveled before the prefabricated bricks can be laid directly. Due to the large area and simple construction steps, rapid laying can be achieved. Multiple sets of support columns 4 and support blocks 5 provide stable support for the top surface 1, dispersing stress. Steel mesh 7 enhances the compressive strength of the top surface 1 and bottom surface 2, thereby increasing the load-bearing capacity of the top surface 1. The filler is a lightweight water-repellent material, such as polystyrene board or polyurethane foam. This lightweight water-repellent material has excellent water-repellent properties, effectively reducing the overall moisture content of the paving bricks. In cold regions, it prevents damage caused by water freezing. The frost heave phenomenon is mitigated, thus protecting the material structure of the paving bricks from frost damage. The filler 6 has thermal insulation properties, providing insulation for the roadbed and preventing cracking due to low temperatures. No separate insulation layer or subbase is needed, saving paving costs and significantly shortening the construction cycle. Compared to paving methods that combine multiple smaller square bricks, this method offers a high degree of integration. The filler 6 acts as a mold during paving brick casting, occupying the space between the top surface 1 and bottom surface 2 of the paving brick after casting, providing support. This ensures the overall stability of the paving bricks while being lighter and saving production costs. Multiple support columns 4 are distributed horizontally and vertically between the top surface 1 and bottom surface 2, forming a honeycomb structure. The honeycomb structure can significantly improve the overall structural strength by dispersing loads through geometric shape while reducing material usage. The synergistic effect of each unit enables the structure to withstand multi-directional loads, evenly distribute stress, reduce local stress concentration, and avoid structural instability. When paving bricks are used for a long time or when the top surface of the paving bricks is cracked due to external forces, the honeycomb distribution structure can effectively prevent the extension of cracks, making the overall structural integrity of the paving bricks higher and less prone to large-area cracking. When the paving bricks are damaged locally, the honeycomb distribution structure of multiple sets of support columns can effectively prevent the spread of damage, reduce losses, and facilitate subsequent repairs, reducing repair costs.Due to its lightweight structure, it can produce relatively large paving bricks, enabling faster road paving. The gaps between the bricks are small, reducing construction difficulty and shortening the construction period. The on-site construction area is small, and the high dimensional precision of the prefabrication ensures construction quality. Utilizing economies of scale, the project cost is low, and it is easy to achieve and maintain a clean and orderly modern construction site.

[0023] In this invention, the filler is a lightweight water-repellent material, such as polystyrene board or polyurethane foam board. The filler serves as a mold for the precast casting process of the paving brick body, and remains in the cavity structure after the paving brick body is cast.

[0024] Specifically, the lightweight water-repellent material, used as a casting mold, has the properties of being lightweight, water-repellent, and heat-insulating. After casting, it can be directly embedded into the cavity structure formed by the top surface 1 and bottom surface 2 of the paving brick without needing to be removed. The lightweight water-repellent material filler 6 provides support for the top surface 1. Furthermore, due to the excellent water-repellent properties of the lightweight water-repellent material, it can reduce the overall moisture content of the paving brick. When applied in extremely cold regions, it can prevent frost heave caused by water freezing, thereby protecting the material structure of the paving brick from frost heave damage.

[0025] In this invention, the multiple sets of support columns 4 are evenly distributed within the cavity.

[0026] Specifically, multiple sets of support columns are evenly arrayed, with horizontal and vertical arrangements interspersed to form a honeycomb structure, which effectively and evenly disperses stress, reduces local stress concentration, and avoids structural instability.

[0027] In this utility model, the support block 5 and the support column 4 are integrally cast and molded structures, and the diameter of the end of the support block 5 away 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, as a reinforcing structure of the support column 4, can further increase the contact area between the support column 4 and the top surface 1 and the bottom surface 2, thereby strengthening the load-bearing capacity of the top surface 1 and the bottom surface 2 and improving the compressive strength of the paving bricks.

[0029] In use, the reinforcing mesh 7 and the filler 6 are placed inside the concrete casting mold, with the filler 6 positioned between two sets of reinforcing mesh 7. Concrete is then poured into the paving brick mold for shaping. Both the filler 6 and the reinforcing mesh 7 are encased in concrete. Because the filler 6 is located inside the paving brick, and the paving brick is not solid concrete, it is relatively lightweight and can be made into square bricks with a relatively large area. The entire prefabrication process of the paving brick is carried out in the factory workshop. The advantage is that the environmental factors in the workshop, such as temperature and humidity, can be adjusted according to adaptability to meet the material performance requirements of the concrete, thereby optimizing its material performance, ensuring the casting quality of the paving brick, and extending its service life. To avoid quality defects in paving bricks caused by environmental factors during on-site pouring, the prefabricated bricks can be laid directly after the roadbed is compacted and leveled. Due to the large area and simple construction steps, rapid paving can be completed. Multiple sets of support columns 4 and support blocks 5 provide stable support for the top surface 1 and distribute stress. The steel mesh 7 improves the compressive strength of the top surface 1 and bottom surface 2, thereby increasing the load-bearing capacity of the top surface 1 of the paving bricks. The filler 6 has thermal insulation properties, which can insulate the roadbed and prevent cracking due to low temperatures. There is no need to lay a separate insulation layer and subbase, thus saving paving costs and greatly shortening the construction period. Compared to paving with multiple smaller square bricks, this method offers a high degree of integration. The filler 6 acts as a mold during the paving brick casting process, occupying the space between the top surface 1 and bottom surface 2 of the paving brick after casting to provide support. This ensures the overall stability of the paving brick while also being lighter and saving production costs. The filler is made of lightweight, water-repellent materials, such as polystyrene board or polyurethane foam board, which have excellent water-repellent properties. This effectively reduces the overall moisture content of the paving brick, preventing frost heave caused by freezing in cold regions, thus protecting the paving brick's material structure from frost damage. Multiple support columns 4 are staggered horizontally and vertically between the top surface 1 and bottom surface 2, forming a honeycomb structure. The honeycomb structure can significantly improve the specific strength of the overall structure by dispersing the load through its geometric shape while reducing the amount of material used. The synergistic effect of each unit enables the structure to withstand multi-directional loads, evenly distribute stress, reduce local stress concentration, and avoid structural instability. When the top surface of the paving brick is cracked due to long-term use or external forces, the honeycomb distribution structure can effectively prevent the extension of cracks, making the overall structural integrity of the paving brick higher and less prone to large-area cracking. When the paving brick is damaged locally, the honeycomb distribution structure of multiple sets of support columns can effectively prevent the spread of damage, reduce losses, and facilitate subsequent repairs, thus reducing repair costs.Due to its lightweight structure, it can produce relatively large paving bricks, enabling faster road paving. The gaps between the bricks are small, reducing construction difficulty and shortening the construction period. The on-site construction area is small, and the high dimensional precision of the prefabrication ensures construction quality. Utilizing economies of scale, the project cost is low, and it is easy to achieve and maintain a clean and orderly modern construction site.
