Description

Technical Field

[0001] The utility model relates to the technical field of road facilities, in particular to a curbstone. Background Art

[0002] Curbstones are marker stones between the edge of the road and structures such as sidewalks and green belts. They have the function of separating different functional spaces on the road and increasing the stability of the road surface. They are necessary components for road construction. Currently, commonly used curbstones are divided into traditional cement concrete and stone types according to their materials. Traditional concrete curbstones are limited by the material itself, as well as the influence of external environments such as snow-melting agents, freeze-thaw, and rain erosion. They show shortcomings such as poor durability, rough surface, easy to have missing edges, corners, and short service life, which seriously affect the overall landscape of the road, require frequent maintenance, and have high operation and maintenance costs. Although stone curbstones have good mechanical properties and excellent corrosion resistance, they cause great damage to the natural environment during mining and production, and have a high cost.

[0003] Both types of curbstones basically adopt solid structure, with large overall weight, time-consuming and labor-intensive installation, and inconvenient adjustment. Although the hollow structure can reduce the weight of the curbstone, in some cases, the curbstone needs to be divided to meet the installation requirements of different road lengths. There is a large gap at the end of the hollow curbstone after division, which is inconvenient to grout and install with the adjacent curbstone, causing great difficulties in the construction and installation of the curbstone.

[0028] Figure 1 It is a schematic diagram of the overall structure of the curb stone provided by the embodiment of the utility model; Figure 2 is a vertical cross-sectional view of a curbstone provided by an embodiment of the utility model;

[0029] See also Figure 1 and Figure 2 , the utility model embodiment provides a curb stone, such as Figure 1 As shown, the curbstone is a hollow structure for limiting a hollow chamber 20. The hollow chamber 20 extends along the length direction of the curbstone. A movable rib 30 is arranged in the hollow chamber 20. The shape of the movable rib 30 is adapted to the cross-sectional shape of the hollow chamber 20, and the movable rib 30 is arranged parallel to the end wall of the body.

[0030] The curbstone is a rectangular parallelepiped with a curved chamfer on the side close to the road. Figure 1It can be understood that the curb provided by the embodiment of the utility model can effectively reduce the weight of the curb by providing the hollow chamber 20, which is conducive to the extension design of the length of a single curb, and can greatly improve the installation progress in the straight section and the large radius curve section of the road, improve the construction efficiency, and reduce the production cost. In addition, by providing the movable rib 30 in the hollow chamber 20, the problem of weak side wall force of the curb during transportation, stacking and operation can be solved. Compared with the prior art, the curb provided in the embodiment of the utility model has a movable rib 30 in the hollow chamber 20. Thus, when the curb needs to be cut and installed at the end of the road or a small radius curve section, the end after cutting can be sealed by the movable rib 30. In other words, the opening 40 at the end of the curb after segmentation can be sealed by the movable rib 30. Thus, when pouring cement mortar between two adjacent curbs, the movable rib 30 can act as a mold, thereby preventing cement mortar from flowing into the hollow chamber 20, solving the assembly problem between the segmented curb and the adjacent curb, and improving the assembly efficiency.

[0031] The following is a specific example provided by an embodiment of the utility model. During the on-site construction process, a certain gap (approximately less than 1 cm) needs to be left between the curb and the adjacent curb, and cement mortar needs to be poured between the two adjacent curbs, so the two ends of the curb need to be closed. The standard parts of the curb are constants. In actual applications, the length of the road is not an integer multiple of the length of the curb. The end needs to be cut on-site according to the actual length. The cutting surface is only a thin wall, which is not conducive to installation. The installation problem can be solved by setting up movable ribs 30. In addition, the road is not all straight lines. In the curved range, a straight line is used instead of a curve. The smaller the curve radius, the smaller the required straight line length. The standard parts of the curb are relatively long. In order to achieve the installation effect in the small radius curve range, they need to be cut into several sections for installation. As above, movable ribs 30 are set to solve this problem.

[0032] Figure 3 is an inner cross-sectional view of a curbstone provided by an embodiment of the utility model; Figure 4 It is a top sectional view of a curb provided in an embodiment of the utility model.

[0033] See also Figures 1 to 4In an optional embodiment of the utility model, an opening 40 is provided on the bottom wall of the curbstone, and the opening 40 is connected to the hollow chamber 20. It can be understood that the design of the opening 40 can further reduce the weight of the curbstone, making it easier to install and use. In addition, when installing the movable rib 30, the movable rib 30 can be directly embedded into the hollow chamber 20 through the opening 40, which can greatly improve the installation efficiency of the movable rib 30, thereby improving the overall installation efficiency of the curbstone. It can also be understood that, based on the aforementioned embodiment, in this embodiment, by providing the movable rib 30, the contact area between the curbstone and the ground can be increased.

[0034] Continue reading Figures 1 to 4 In an optional embodiment of the utility model, the opening 40 extends along the length direction of the hollow chamber 20. It can be understood that by extending the opening 40, a more flexible installation space can be provided for the movable rib 30. For example, when installing the movable rib 30, it can be directly inserted into the preset position without considering reopening the opening 40 on the bottom wall of the curb. In addition, if the movable rib 30 deviates from the preset position after insertion, it can be flexibly adjusted through the opening 40, which greatly improves the flexibility of the movable rib 30 and increases the convenience of assembly.

[0035] Continue reading Figure 1 In an optional embodiment of the utility model, the length of the curb is a, wherein the value range of a is 1m≤a≤2m, for example, a can be 1.1m, 1.2m, 1.3m, 1.4m, 1.5m, 1.6m, 1.7m, 1.8m, 1.9m or 2.0m, and can be set adaptively according to the actual situation. It can be understood that the curb provided by the embodiment of the utility model, by limiting the length of the curb within the above-mentioned value range, can make the curb have a longer length under the condition of appropriate weight. During assembly and installation, the curb with a longer length can reduce the paving steps of the entire road section, and can greatly improve the paving speed of the entire curb. On the basis of the above-mentioned embodiment, it can also be understood that the length of the curb in this embodiment is relatively long. In the actual transportation and installation process, the movable rib 30 can play a role of reinforcement to avoid the problem of weak side wall stress caused by the curb being too long and hollow inside.

[0036] In an optional embodiment of the utility model, a plurality of movable ribs 30 are provided, and the plurality of movable ribs 30 are arranged at intervals along the length direction of the hollow chamber 20. It can be understood that the interval arrangement of the plurality of movable ribs 30 can improve the stability of the curbstone and avoid the problem of weak side wall force due to the curbstone being too long and hollow inside. It can also be understood that on the basis of the aforementioned embodiment, when the bottom wall of the curbstone is provided with an opening 40, the plurality of curbstones can further increase the contact area between the curbstone and the ground, and improve the stability of the overall structure of the curbstone.

[0037] In an optional embodiment of the utility model, a preset gap is provided between the movable rib 30 and the side wall of the hollow chamber 20, and the preset gap has a value range of 0.5 cm to 1.0 cm. For example, a preset gap of 0.5 cm, a preset gap of 0.7 cm, or a preset gap of 1.0 cm can be set. Specifically, it can be adaptively set according to actual conditions. It can be understood that by setting the preset gap, when installing the movable rib 30, cement mortar can be applied to the side wall of the movable rib 30 first, and then the hollow chamber 20 of the curb can be inserted, which can facilitate the installation of the movable rib 30 and increase the installation and laying speed of the curb.

[0038] In the optional embodiment of the utility model, the curbstone includes an ultra-high performance concrete body 10, and the hollow chamber 20 is arranged in the ultra-high performance concrete body 10, or the curbstone includes a high performance concrete body, and the hollow chamber 20 is arranged in the high performance concrete body. It can be understood that ultra-high performance concrete (Ultra-High Performance Concrete) or high performance concrete (High Performance Concrete) has the characteristics of high strength, high density, high toughness and high durability, and can effectively avoid external environmental influences such as snow melting agents, freeze-thaw, and rain erosion. At the same time, its good mechanical properties can meet the lightweight structural design of the curbstone. Compared with traditional concrete materials, it has the advantages of good durability, resistance to snow melting agents, freeze-thaw and rain erosion, etc. Compared with granite materials, it has the advantages of environmental protection, low carbon and sustainability.

[0039] In an optional embodiment of the utility model, a first threading hole is provided at the end of the body, and the first threading hole is connected to the hollow chamber 20. It can be understood that by providing the first threading hole, the subsequent laying of pipelines and cables can be facilitated, and the function of the curbstone to reserve pipelines can be realized, providing space for the laying of pipelines or cables such as lighting, monitoring, and information, and realizing the intensive arrangement of facilities on the road. At the same time, it can also be used as a reserved space to avoid the need to excavate the road for laying lines later, greatly improving the practicality and versatility of the curbstone. It should be noted that the position and number of the first threading holes can be adaptively set, for example, three, four or five first threading holes are set, and the first threading holes can be set on the upper side, lower side or middle of the end of the body.

[0040] In an optional embodiment of the utility model, the movable rib 30 is provided with a second threading hole corresponding to the first threading hole, and the position and number of the second threading hole correspond to the first threading hole. In an optional embodiment of the utility model, the first threading hole and the second threading hole can be coaxially arranged, so that the threading of pipelines and cables can be facilitated and the installation efficiency of pipelines and cables can be improved. At the same time, the movable rib 30 can also serve as a supporting device to provide certain support and restraint effects on pipelines and cables, so that the combination of pipelines and cables with curbs is more reasonable.

[0041] It should be noted that the technical solutions in various embodiments of the present utility model can be combined with each other, but the basis for the mutual combination is that it can be implemented by ordinary technicians in the field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist, that is, it does not belong to the protection scope of the present utility model.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
