Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a prefabricated modular curbstone. Background Technology

[0002] Curbstones are boundary stones placed between carriageways, sidewalks, green belts, and other structures in road engineering. They are used to clearly define road boundaries, separate traffic spaces, and also serve drainage, aesthetic, and protective functions. Based on their relative height to the road surface, curbstones typically come in two forms: flat curbstones and upright curbstones. Flat curbstones (or simply flat stones) are boundary stones whose top surface is basically flush with or slightly higher than the road surface, and are commonly used at entrances and exits, accessible pathways, and locations where convenient vehicle passage is required. Upright curbstones, on the other hand, are boundary stones whose top surface is higher than the road surface, typically 10–15 cm high. They are used to separate carriageways from sidewalks, green belts, and other areas, effectively preventing vehicles from driving off the road.

[0003] The common traditional method for installing curb stones involves laying flat curb stones and upright curb stones separately and installing them horizontally. While this method is simple in structure, it often suffers from low construction efficiency and difficulty in ensuring installation accuracy in practice.

[0004] Existing technology (such as Chinese patent application CN110424226A) proposes an overall elongated curbstone structure comprising a left portion, a lower portion, and a right portion connected to each other, forming a groove along the length of the three portions. The groove is located in the middle and is used to accommodate the curbstone. In this structure, the left portion is higher than the right portion, the inner surface of the left portion serves as a backrest for the curbstone, and the upper surface of the right portion is used to cast a square strip stone. The right portion, the square strip stone, and the curbstone simultaneously serve as side molds for the road asphalt.

[0005] However, the existing technology still has shortcomings: the groove formed by the curbstone increases the manufacturing and installation steps, which is not conducive to improving construction efficiency; at the same time, the right side of the flat stone also requires separate components such as the pressure strip stone, resulting in a large number of parts and further increasing construction complexity; in addition, existing curbstones usually do not have a dedicated handling and connection structure, requiring overall lifting or handling during laying, which is not only inefficient and time-consuming, but also poses safety hazards during handling. In summary, the technical problems of complex construction procedures and low construction efficiency still exist.

[0006] Therefore, this utility model provides a prefabricated modular curbstone, which can simplify the construction process, reduce the installation difficulty, thereby shorten the construction time and improve the construction efficiency. Utility Model Content

A first drain outlet is provided on the second sub-side, and a second drain outlet is provided on the second contact surface. Both the first and second drain outlets are connected to pipes inside the curbstone, forming a drainage channel that runs through the curbstone.

[0012] Preferably, the drainage channel is a horizontal channel that passes through the curb stone, or a channel that is inclined from the first drainage outlet to the second drainage outlet.

[0013] Preferably, there are three curb stones, and the curb stone located next to the manhole cover is provided with the first drain outlet and the second drain outlet.

[0022] Please see Figures 1 to 10 As shown, this utility model provides a prefabricated modular curbstone, comprising: a flat stone 1, the flat stone 1 including a first flat stone part 11 and a second flat stone part 12, the first top surface 111 of the first flat stone part 11 being higher than the second top surface 121 of the second flat stone part 12, the first flat stone part 11 and the second flat stone part 12 forming an L-shape, the flat stone 1 being used for paving on the ground; at least one upright curbstone 2, the upright curbstone 2 being disposed on the second top surface 121 of the second flat stone part 12; wherein, both opposite sides of the flat stone 1 are provided with a transport connection structure 13.

[0023] This utility model's curbstone adopts an L-shaped structure, instead of the groove-type accommodating form of existing technologies. Through a reasonable modular combination method, it simplifies the construction process, reduces installation difficulty, and shortens construction time. It also has advantages such as convenient installation, time and labor saving, structural stability, and high construction precision. Furthermore, it eliminates the need for separate pressure strips, reducing the number of components and making the construction process simpler and further improving construction efficiency. In addition, the two opposite sides of the flat stone are equipped with handling connection structures, allowing for manual handling or mechanical hoisting, which not only improves construction efficiency but also enhances the convenience and safety of handling.

[0024] In one embodiment, the flat stone 1 includes a first flat stone portion 11 and a second flat stone portion 12. For example... Figure 3 and Figure 4 As shown, the first flat stone part 11 includes a first top surface 111, a second side surface 112, a first mating surface 113, and a first bottom surface 114; the second flat stone part 12 includes a second top surface 121, a second side surface 122, and a second bottom surface 123; wherein the first bottom surface 114 and the second bottom surface 123 are located on the same plane.

[0025] Furthermore, the second top surface 121 includes a first sub-top surface 1211 and a second sub-top surface 1212. The first sub-top surface 1211 is fitted to the third bottom surface 24 of the curbstone 2, so that the curbstone 2 is securely installed on the first sub-top surface 1211 of the second top surface 121 and covers the first sub-top surface 1211.

[0026] In one feasible way, such as Figure 4 As shown, the width of the second top surface 121 is W1, and the width of the third bottom surface 24 of the curbstone 2 is W2. Specifically, the ratio of W2 / W1 can be set to 1 / 2, for example, W2 is 125mm and W1 is 250mm. By setting the width of the curbstone 2 and the width of the second top surface 121 of the flat stone 1 in a half-proportion, it can be ensured that symmetrical support areas are left on both sides when the curbstone 2 is installed, thereby improving the balance of force and stability, and avoiding tilting or loosening due to offset; at the same time, this proportional relationship facilitates modular design and standardized production, further improving the convenience and adaptability of construction and installation.

[0027] like Figures 1 to 4 As shown, the curbstone 2 includes a third top surface 21, a first contact surface 22 adjacent to the first flat stone portion 11, a third bottom surface 24 that is in contact with the second top surface 121 and is disposed opposite to the third top surface 21, a second contact surface 23 disposed opposite to the first contact surface 22, and a fifth side surface 26 and a sixth side surface (not shown in the figure) disposed opposite to each other.

[0028] Furthermore, a portion of the first contact surface 22 is fitted to the first mating surface 113 of the first flat stone portion 11, that is, the first contact surface 22 includes a second sub-side surface 222 and a first sub-side surface 221 fitted to the first mating surface 113 of the first flat stone portion 11.

[0029] The second sub-side surface 222 extends from the first top surface 111 of the flat stone 1 in a direction away from the bottom surface 24, forming the upper side surface of the edging stone 2.

[0030] In one embodiment, such as Figure 10 As shown, a first drainage outlet 25 is provided on the second sub-side 222. The first drainage outlet 25 is connected to a pipe (not shown in the figure) inside the curbstone 2, forming a drainage channel penetrating the curbstone 2. The drainage channel is connected to the sewer of the manhole cover 4 installed on the sidewalk 3. When it rains, rainwater from the asphalt pavement 5 can flow through the first drainage outlet 25, through the pipe inside the curbstone 2, to the sewer. This has the advantages of enabling rapid drainage of road surface water and preventing water accumulation at the junction of the curbstone and the sidewalk, thereby improving drainage efficiency and road safety. Compared with the existing technology where the curbstone does not integrate a drainage channel and relies on a separate rainwater inlet or ditch for drainage, this application effectively reduces construction complexity and maintenance costs by pre-setting a drainage channel in the curbstone.

[0031] In another embodiment, a third drain outlet can be provided at one end of the first top surface 111 of the first flat stone part 11 of the flat stone 1, near the first contact surface 22 of the edging stone 25. A fifth drain outlet can be provided on the first sub-side surface 221 of the first contact surface 22 of the edging stone 2, i.e., the sub-side surface that is in contact with the first mating surface 113 of the flat stone 1. At the same time, a fourth drain outlet communicating with the third and fifth drain outlets is also provided on the first mating surface 113, so as to form a drainage channel within the flat stone 1 and the edging stone 2. When it rains, rainwater flows through the third, fourth, and first drain outlets, sequentially through the internal pipes of the flat stone 1 and the internal pipes of the edging stone 2, and then into the sewer. This has the advantages of achieving integrated drainage between the flat stone and the edging stone, improving the continuity and smoothness of the drainage path, avoiding local water accumulation or leakage, and reducing the construction workload of separately digging ditches, while improving the overall integrity and durability of the modular structure.

[0032] Furthermore, the first drainage outlet 25 can be square in shape, which has the advantages of easy processing, smooth drainage and high compatibility with modular splicing structure; of course, it can also be circular, elliptical, long strip or other polygonal structure to adapt to different drainage needs and construction environment, and there is no restriction here.

[0033] Furthermore, a detachable filter screen or grid structure can be added to the first drainage outlet 25 of the curb stone to intercept fallen leaves, sand and gravel and other debris, prevent the drainage outlet from being blocked, and facilitate later maintenance.

[0034] It is understood that the second contact surface 23 of the curbstone 2, which is opposite to the first contact surface 22, is provided with a second drain outlet (not shown in the figure). This second drain outlet is connected to the first drain outlet 25 of the first contact surface 22, as well as the internal pipes of the curbstone 2, and is also connected to the sewer. Since the second contact surface 23 is fitted against one side of the sidewalk 3, the size of the second drain outlet can be set to be the same as the size of the first drain outlet 25. Of course, they can also be set differently, which is not limited here.

[0035] In one embodiment, the drainage channel is a horizontal channel penetrating the curbstone 2, or a channel inclined from the first drain outlet 25 to the second drain outlet. That is, the drainage channel formed by the pipe inside the curbstone 2, the first drain outlet 25, and the second drain outlet can be a horizontal channel or an inclined channel from the first drain outlet 25 to the second drain outlet.

[0036] It should be noted that when the drainage channel is horizontal, it has the advantages of simple structure, easy processing and installation, and the ability to maintain the overall strength and stability of the curb stone while ensuring drainage capacity. When the drainage channel is inclined, it has the advantages of using the height difference to achieve rapid flow guidance, speeding up the drainage efficiency of accumulated water, reducing the possibility of water stagnation inside the curb stone, and thus further improving drainage performance.

[0037] Furthermore, a plurality of edging stones 2 are provided on the second sub-top surface 1211 of the second top surface 121 of the second flat stone part 12 of the flat stone 1. At least one edging stone 2 includes a first drainage outlet 25 disposed on the first contact surface 22 and a second drainage outlet disposed on the second contact surface 23. Specifically, the first drainage outlet 25 and the second drainage outlet are provided on the edging stone 2 located near the side of the manhole cover 4, such as... Figure 10 As shown, three curb stones 2 can be set. The curb stone 2 located next to the manhole cover 4 can be set with the first drainage outlet 25 and the second drainage outlet. That is, which curb stone 2 is set with the drainage outlet can be determined by the position of the manhole cover 4.

[0038] In a specific scenario, such as Figure 10 As shown, the flat stone 1 is provided with three edging stones 2, and at least one edging stone 2 includes the first drain outlet 25 and the second drain outlet.

[0039] In one embodiment, such as Figures 1 to 9As shown, the transport connection structure 13 includes a transport hole 131 (or transport eye) and a retainer 132. The retainer 132 includes an arc segment 1321 and a straight segment 1322. The straight segment 1322 can be inserted into the transport hole 131 to achieve a detachable connection. Preferably, the straight segment 1322 has threads (not shown in the figure) to achieve reliable fixation through threaded engagement.

[0040] Of course, in other embodiments, the straight segment 1322 can also be connected to the transport hole 131 by means of a snap, pin, or other mechanical connection. The arc segment 1321 is used for transport tools or manual hooking to achieve the fixing and transport of the curbstone.

[0041] This embodiment, through the combined design of the transport hole 131 and the buckle 132, allows the curbstone to be flexibly transported manually or hoisted mechanically according to construction needs. The operation is simple, the structure is sturdy, and the safety and adaptability of the transport are improved. At the same time, the buckle 132 is composed of an arc segment 1321 and a straight segment 1322. The arc segment 1321 is easy to hang and distributes the force evenly, which can effectively avoid local stress damage. The straight segment 1322 cooperates with the transport hole 131 to achieve stable installation and quick disassembly, thus combining the advantages of strength, reliability and reusability.

[0042] The arc segment 1321 can be as follows: Figure 8 and Figure 9 The circular structure shown is a closed structure, which has the advantages of uniform stress distribution, high overall strength, and easy connection in all directions; it can also be an open arc structure, which is non-closed and has the advantages of simple processing, light weight, and easy quick connection and disassembly.

[0043] It should be noted that, in terms of stress distribution: a closed circular structure forms a complete ring under stress, which can evenly distribute tensile, compressive, and torsional forces across the entire circumference, thus avoiding localized stress concentration. Even during long-term repeated handling or hoisting, it is less prone to breakage or damage. In contrast, an open circular arc structure, due to the presence of openings, is more likely to form stress concentration points at the openings under stress, making it more susceptible to deformation, tearing, or breakage over long-term use, resulting in relatively poor durability.

[0044] In terms of handling safety: the closed circular structure is more robust and can be attached to hooks, rings, wire ropes, etc. at any angle. It is stable and not easy to slip off. While the non-closed open arc is convenient to attach, the presence of the opening may lead to the risk of falling off or getting stuck in some situations.

[0045] Therefore, compared with the open arc structure, the closed circular structure has stronger resistance to deformation and durability in the prefabricated modular curbstone of this utility model. It can maintain stability during long-term repeated handling or hoisting and significantly improve the safety of handling operations.

[0046] In one embodiment, the flat stone 1 includes a first side 122 and a second side 112 disposed opposite to each other, and a third side 14 and a fourth side (not shown in the figure) disposed adjacent to the first side 122 and the second side 112; wherein, in this application, the first side 122 and the second side 112 may be in the length direction of the flat stone 1, and the third side 14 and the fourth side are respectively in the width direction, and the third side 14 and the fourth side are disposed opposite to each other; further, the third side 14 and the fourth side may be disposed opposite to each other.

[0047] Specifically, the first side 122 and the second side, and / or the third side and the fourth side are provided with the transport connection structure 13. The number of transport connection structures 13 can be set to at least two. The advantage of setting at least two transport connection structures is that they can form a stable force balance during transport, avoid tilting or shaking caused by single-point force, thereby improving the safety and ease of operation of the transport process.

[0048] The transport connection structure 13 can be located in the middle, at both ends, or at a predetermined uniform interval on the corresponding side, so as to flexibly adapt to different transport requirements.

[0049] In one feasible approach, the transport connection structure 13 can be positioned in the middle to facilitate single-point central attachment; when distributed at both ends or at even intervals, it is beneficial for two or more points to be subjected to force simultaneously, achieving more stable hoisting and transport.

[0050] In another possible implementation, at least two transport holes 1311 are provided on the first side 122 and the second side 112, namely a first transport hole 1311 and a second transport hole 1312, wherein one of the transport holes (i.e., the first transport hole 1311) is located near the third side 14 and a gap is reserved between it and the third side 14, and the other transport hole (i.e., the second transport hole 1312) is located near the fourth side and a gap is reserved between it and the fourth side.

[0051] It should be noted that, as Figure 8 and Figure 9As shown, the transport connection structure 13 includes a transport hole 131 and a buckle 132 which can be set near the two ends of the flat stone 1. This can maintain the symmetry of the force during transport and effectively prevent the flat stone 1 from tilting or rotating laterally, thereby further improving the balance and reliability of the transport process.

[0052] Furthermore, the ratio of the interval distance to the length of the first side surface 122 is 1 / 10, where the length refers to the direction in which the edging stones 2 are placed sequentially along the second top surface 121 of the flat stone 1, i.e. Figure 3 The direction of L1 shown is such that the width is the direction perpendicular to the length from the first top surface 111 to the second top surface 121, i.e. Figure 4 The direction of W1 is shown. (As shown in the image) Figure 3 , Figure 8 and Figure 9 As shown, assuming the length of the first side 122 of the flat stone 1 with the transport connection structure 13 is L1, the flat stone 1 has transport connection structures 13 near both ends, and the reserved interval distance from the first transport hole 1311 of each transport connection structure 13 to the adjacent third side 14 of the flat stone 1 is L2. L2 / L1 can be set to 1 / 10, for example, L1 is set to 2000mm and L2 is set to 200mm. This proportional design in the prefabricated modular curbstone of this utility model has the following advantages: it can ensure that the transport connection structure is in a reasonable position near the end, avoiding insufficient end strength or cracking due to being too close to the edge; it can also ensure that the spacing of the transport connection structure is moderate, improving the overall stress balance and stability, thus taking into account both structural strength and operational convenience in actual construction and transportation, and further improving the safety and reliability of construction.

[0053] It should be noted that the specific ratio of L2 / L1 is not limited to 1 / 10. Those skilled in the art can adjust this ratio according to the actual size of the flat stone and the handling requirements, and all such adjustments are within the protection scope of this utility model.

[0054] In other embodiments, the transport connection structure 13 may also be provided on the first side 122, the second side, the third side 14 and the fourth side, which has the following advantages: it can be attached and transported from any direction, without being restricted by the site, significantly improving the adaptability and flexibility of the prefabricated modular curbstone in different construction scenarios, while improving transport efficiency and construction safety.

[0055] In one embodiment, such as Figure 3 and Figure 4As shown, the length L1 of the second top surface 121 of the flat stone 1 is greater than the length L3 of the third bottom surface 24 of the edging stone 2, and the width W1 of the second top surface 121 of the flat stone 1 is greater than the width W2 of the third bottom surface 24 of the edging stone 2. This arrangement allows for the placement of multiple edging stones on the same flat stone, forming a modular combination structure. Simultaneously, symmetrical clearances are reserved at both ends of the flat stone, improving overall stress balance and edge stability, and facilitating drainage, expansion joint installation, and subsequent maintenance and replacement.

[0056] In one embodiment, such as Figure 10 As shown, the side of the curbstone 2 away from the first contact surface 22 of the flat stone 1 (i.e., the second contact surface 23) can be fitted to one side of the sidewalk 3. At this time, at least part of the bottom surface of the sidewalk 3 is set on the second top surface 121 of the flat stone 1. There is no need to set separate components such as paving stones between the two, which has the advantages of reducing material usage, simplifying structure, and reducing construction procedures and costs. In addition, the height of the sidewalk 3 is set to be the same as the height of the curbstone 2, which has the advantages of ensuring flat paving, uniform appearance, and improving the comfort of the connection between the sidewalk and the roadway.

[0057] In one feasible approach, the prefabricated modular curbstone comprises a flat curbstone 1 and three upright curbstones 2, as follows: Figure 1 and Figure 2 As shown, three edging stones 2 are disposed on the second top surface 121 of a flat stone 1. The third bottom surface 24 of each edging stone 2 is fitted to the second top surface 121 of the flat stone 1, and the first side surface 221 of each edging stone 2 is fitted to the first contact surface 113 of the first flat stone portion 11 of the flat stone 1. Further, as... Figure 3 As shown, the length L3 of each curbstone 2 can be different or the same, for example, all 600mm. The length L1 of the second top surface 121 of the flat stone 1 in the direction in which each curbstone 2 is placed can be 1800mm or greater than 1800mm, for example, 2000mm. When L1 is 1800mm, three curbstones 2 can be placed, which has the advantages of compact structure, precise installation and connection, and high overall stability. When L1 is 2000mm, which is greater than 1800mm, after placing three curbstones 2, there are gaps at both ends, which has the advantages of reserving adjustment space, facilitating adaptation to different construction size errors and later maintenance and replacement. Specifically, when the curbstone length is 600mm and the flat stone length is 2000mm, it has the advantages of uniform module specifications, easy standardized production and transportation, and more flexible installation arrangement.

[0058] In one embodiment, the ratio of the height of the second sub-side surface 222 of the curbstone 2 to the height of the first sub-side surface 221 is 1 / 2. For example... Figure 4As shown, the sum of the height of the second sub-side 222 and the height of the first sub-side 221 is H4, and the height of the first sub-side 221 is H2. For example, if H2 is 120mm and H4 is 180mm, then the height of the second sub-side 222 is 60mm, and the ratio of the two is 1 / 2. This design increases the contact area between the lower part of the curb stone and the flat stone, enhances structural stability, and forms an appropriately protruding edge height at the top. This design ensures protection for vehicles and pedestrians while avoiding collisions or construction inconveniences caused by excessive height.

[0059] It should be noted that the height and width of the curbstone 1 are the same, but its length can be set to be the same or different. When the length is set to be the same, it has the advantages of facilitating standardized production and mass manufacturing, making installation more efficient and faster, and resulting in a neat and consistent overall appearance. When the length is set to be different, it has the advantages of being able to flexibly combine according to actual construction needs, adapting to different road section size changes, and improving adaptability.

[0060] like Figure 3 As shown, in one feasible embodiment, the length L3 of the curbstone 1 can be set to 600mm, and the length of the first side 122 of the flat stone 1 can be set to 2000mm. In this case, three curbstones 1 of the same length, for example, each 600mm, can be placed on the second top surface 121, for a total length of 1800mm. With this arrangement, after the three curbstones 1 are placed, reserved gaps are formed at both ends, which has the advantages of facilitating drainage and expansion joint treatment, improving stress balance, and reserving space for maintenance and replacement.

[0061] In one embodiment, the ratio of the width of the third bottom surface 24 of the curbstone 2 to the width of the second top surface 121 is 1 / 2. For example... Figure 4 As shown, the width of the third bottom surface 24 is W2, and the width of the second top surface 121 is W1. W2 / W1 is 1 / 2. For example, W2 is set to 125mm and W1 is set to 250mm. By setting this ratio, symmetrical support areas can be formed on both sides of the bottom of the curbstone 2, which improves the balance of force and the stability of installation, avoids tilting or loosening due to offset, and facilitates modular design and standardized production.

[0062] In one embodiment, the width of the first top surface 111 of the flat stone 1 is greater than the width of the second top surface 121 of the flat stone 1. The second top surface 121 of the flat stone 1 is the surface on which the curb stone 2 is set, while the first top surface 111 is the surface parallel to the asphalt pavement 5. By setting the width of the first top surface 111 to be greater than the width of the second top surface 121 of the flat stone 1, it has the advantages of increasing the contact area with the asphalt pavement, improving overall stability, and avoiding loosening or sinking due to uneven stress.

[0063] Specifically, such as Figure 4 As shown, the width W3 of the first top surface 111 can be set to 350mm, and the width W1 of the second top surface 121 can be set to 250mm. This specific numerical setting has the advantages of reasonable size matching, easy alignment and positioning during construction, and taking into account both structural strength and construction convenience.

[0064] In one embodiment, the flat stone 1 and the curb stone 2 can also be fixed by setting a limiting structure, such as a tenon and groove structure, to prevent the curb stone 2 from shifting laterally during use and improve the stability of the entire curb stone.

[0065] Furthermore, the interior of the flat stone 1 may also be provided with a through-type reserved pipeline channel for laying cables or irrigation water pipes, thereby realizing the integration of functions such as road lighting and greening irrigation.

[0066] It should be noted that the present utility model Figure 3 for Figure 2 The main view of the prefabricated modular curbstone formed by looking from the first side 122 of the flat stone 1 towards the first side 112 of the flat stone 1. Figure 4 For the corresponding Figure 3 The left view; Figure 5 For the corresponding Figure 3 Top view.

[0067] In one embodiment, the flat stone 1 is made of at least one of concrete and granite; the curb stone 2 is made of at least one of concrete and granite. That is, the flat stone 1 and the curb stone 2 can be made of concrete, granite, or a mixture of both.

[0068] In a preferred embodiment, the flat stone 1 and the curb stone 2 are prefabricated using concrete materials, which has the advantages of simple mold-making process, low production cost, and suitability for mass production.

[0069] In another embodiment, the flat stone 1 and the edging stone 2 are made of granite. Compared to concrete, granite is more expensive, but it has the advantages of beautiful natural texture, better hardness and wear resistance, and excellent weather resistance.

[0070] In summary, this utility model provides a prefabricated modular curbstone, comprising: a flat stone, which includes a first flat stone portion and a second flat stone portion, wherein the first top surface of the first flat stone portion is higher than the second top surface of the second flat stone portion, and the first and second flat stone portions together form an L-shaped structure, the flat stone being used for paving on the ground; and at least one upright curbstone, which is disposed on the second top surface of the second flat stone portion; wherein, both opposite sides of the flat stone are provided with a transport connection structure. This utility model, by designing the flat stone as an L-shaped structure and setting an upright curbstone on it, while simultaneously providing transport connection structures on opposite sides of the flat stone, enables the curbstone to be directly installed in a prefabricated manner, avoiding the complex procedures of existing technologies that rely on grooves for containment or multi-component assembly, thereby effectively simplifying the construction process, reducing installation difficulty, shortening construction time, improving construction efficiency, and further enhancing operational safety and adaptability during transport and installation.
