Abstract
Description
Technical Field
[0001] The utility model belongs to the field of road engineering, and in particular relates to a curbstone cushion component. Background Art
[0002] During the current road construction process, curbstones are usually directly laid on a cushion layer of lime soil or cement. Among them, the support stability provided by the lime soil cushion layer is insufficient; and the cement cushion layer usually needs to be poured on site, and the cement curing time is unstable due to weather factors such as temperature and precipitation, resulting in a long construction period for curbstone paving, complex procedures, and high costs. The existing curbstone cushion layer usually lacks support on the side close to the green belt, which can easily cause the curbstone to tilt and fall during the paving process or during service. Furthermore, the existing curbstone cushion layer is also prone to settlement, causing the curbstone to sink or tilt. Therefore, providing a convenient and reliable curbstone cushion layer is of positive significance for improving the quality of curbstone paving and reducing the cost of road maintenance. Utility Model Content
[0003] The utility model aims to provide a curbstone cushion component to improve the efficiency of curbstone paving construction.
[0004] According to an embodiment of the utility model, there is provided a curbstone cushion layer assembly, which includes a main frame, wherein the main frame includes a bottom support body and a side support wall, wherein the bottom support body and the side support wall are perpendicular to each other and are arranged in an L shape; the bottom support body includes a plurality of support frames, wherein the support frames are configured as a cylindrical structure, and the wall of the support frame extends along the thickness direction of the bottom support body; the bottom support body provides bottom support for the curbstone, and the side support wall provides lateral support for the curbstone.
[0005] The main body of the cushion component adopts a frame structure with simple structure and light weight. It can be pre-manufactured in batches using lightweight materials such as engineering plastics, and directly laid on the edge of the roadbed at the construction site, effectively improving construction efficiency; the bottom support frame is filled with sand, gravel and other building materials to enhance the supporting strength of the frame and make the cushion more stable; the bottom support body can provide leveling for the curbstones, side leveling stones or drainage ditches, thereby improving paving efficiency; the side support wall can provide lateral support for the curbstones to prevent the curbstones from falling to the outer side of the road.
[0006] Furthermore, in some embodiments, the bottom support body has a length direction, and the support frame is arranged along the length direction. The support frame is arranged along the length direction, which can provide relatively uniform support in the length direction of the curbstone and improve the support effect of the bottom support body.
[0007] Furthermore, in some embodiments, along the length direction, the length of each support frame does not exceed 1 / 3 of the length of the curbstone. The size of the support frame can be flexibly designed according to the size of the curbstone to be paved. If the length of the support frame does not exceed 1 / 3 of the curbstone, the curbstone will be supported by at least two walls of the support frame in any way of paving, further improving the support effect and structural strength.
[0008] Furthermore, in some embodiments, the main frame also includes a bottom plate, and the bottom plate is configured as a perforated plate. The through holes on the perforated plate can allow water to penetrate; when the support frame is filled with sand, the perforated plate can also allow the sand to flow out. If hollowing occurs under the cushion layer, the flowing sand can play a filling role, improve the stability of the cushion layer, and alleviate the settlement phenomenon.
[0009] Furthermore, in some embodiments, the curbstone cushion assembly further comprises a transverse cover plate, which covers the upper opening of the support frame. The transverse cover plate can improve the structural strength of the support frame, improve the compression resistance, and prevent soil from entering during construction.
[0010] Furthermore, in some embodiments, the transverse cover plate further comprises an extension portion, which extends in a direction away from the side support wall. The extension portion can extend the width of the bottom support body to facilitate leveling for the side flat stones or drainage ditches paved with the curbstones.
[0011] Further, in some embodiments, the extension portion has the same thickness as the bottom support body.
[0012] Furthermore, in some embodiments, a reinforcement structure is provided on the side of the side support wall away from the bottom support body. The reinforcement structure can improve the strength of the side support wall and provide better lateral support for the curbstone.
[0013] Furthermore, in some embodiments, the reinforcement structure is configured as a raised reinforcement rib or reinforcement frame. The gap between the reinforcement ribs and the inside of the reinforcement frame can also be filled with sand or gravel to further improve the stability of the side wall and the supporting effect.
[0014] Furthermore, in some embodiments, the top of the reinforcement structure is configured as an inclined surface and covered with an inclined cover plate. The inclined surface is consistent with the conventional curbstone foundation structure, and the inclined cover plate can enhance the strength of the reinforcement structure and prevent soil from entering.

DETAILED DESCRIPTION
[0021] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

The phrase appearing in various locations in the specification does not necessarily refer to the same embodiment, nor is it limited to mutually exclusive independent or alternative embodiments. Those skilled in the art should be able to understand that the embodiments herein may be combined with other embodiments without causing structural conflicts.

[0025] In the description herein, "plurality" means at least two.
[0026] At present, in the process of road construction, curbstones are usually laid directly on the soil roadbed or cement cushion layer to isolate the road from the outer areas of the road, such as sidewalks or green belts. However, the soil roadbed has poor supporting effect. Under long-term service conditions, it is easy to form cavities or settlement under the curbstones due to factors such as precipitation, causing the curbstones to fall or collapse, affecting the paving effect. The cement cushion layer usually needs to be poured on site, and the curbstones can be laid after the cement cushion layer is fully solidified. Under humid, cold or rainy weather conditions, the cement cushion layer is difficult to solidify quickly, which can easily cause delays in the progress of the project; further, the pouring of the cement cushion layer itself is large in amount, complicated in process, and high in cost, which also increases the cost of curbstone paving construction and is inefficient.
[0027] In order to solve the above problems, an embodiment of the utility model provides a curbstone cushioning assembly, which can realize the rapid laying of curbstones at a relatively low cost.
[0028] In one embodiment, the structure of the curbstone cushion assembly is as follows: Figure 1 As shown, it includes a main frame 1, the main frame 1 includes a bottom support body 11 and a side support wall 12, the bottom support body 11 and the side support wall 12 are perpendicular to each other and are arranged in an L shape, the bottom support body 11 extends in the horizontal direction, and the side support wall 12 extends in the vertical direction. Among them, the bottom support body 11 includes four support frames 111, each support frame 111 is configured as a cylindrical structure extending along the thickness direction of the bottom support body 11 (i.e., the height direction when the curbstone is laid), and the support frame wall body 112 extending in the vertical direction surrounds the rectangular cylindrical wall of the support frame 111; each support frame 111 extends along the length direction of the bottom support body 11 (i.e., the length direction when the curbstone is laid). When the curbstone is laid, the bottom support frame 11 provides the lower support of the curbstone, and the side support wall 12 provides the lateral support of the curbstone from the outside of the roadbed to prevent the curbstone from falling to the outside. When paving the curbstone, sand or gravel may be filled in the support frame 111 to increase the structural stability of the main frame 1 . The sand filling may also enhance the support strength of the main frame 1 .
[0029] In some embodiments, the support frame 111 in the bottom support body 11 may also be arranged in other forms, such as a 2×4 array, to increase the distribution density of the support frame wall 112 per unit area and further improve the support strength.
[0030] A reinforcement frame 121 as a reinforcement structure is provided on the side of the side support wall 12 facing away from the bottom support body 11 (i.e., the side facing the outside of the roadbed when the curbstone is laid). The reinforcement frame 121 is also configured as a cylindrical structure extending in the vertical direction and is surrounded by a rib plate 122 and an outer wall plate 123. The reinforcement frame 121 can improve the strength of the side support wall 12 and improve the lateral support strength for the curbstone. In some embodiments, the reinforcement frame 121 can also be filled with sand or gravel to improve the stability and support strength of the side support wall.
[0031] In some embodiments, the outer wall plate 123 may also be omitted, and only the rib plate 122 serves to strengthen the side support wall.
[0032] In a preferred embodiment, a bottom plate 13 is also provided at the bottom of the main frame 1, and the bottom plate 13 is configured as a perforated plate. The bottom plate 13 extends at the bottom of the main frame 1 to form the bottom wall of the support frame 111 and the reinforcement frame 121. The perforated plate structure of the bottom plate 13 allows water to penetrate, avoiding water accumulation inside the curbstone cushion layer assembly; at the same time, when the support frame 111 and the reinforcement frame 121 are filled with sand, once hollows appear under the bottom plate 13, the sand can flow out through the plate holes to fill and compensate for the hollows, thereby improving the stability of the cushion layer, alleviating or avoiding the tilting or settlement of the curbstone caused by hollows, and improving the quality of curbstone paving.
[0033] In a preferred embodiment, if Figure 3 As shown, the curbstone cushion assembly also includes a transverse cover plate 2, which includes a transverse sealing plate 21. The lower surface of the transverse sealing plate 21 is provided with raised ribs 22, which are surrounded by a frame shape and can be inserted into the support frame 111 to be fixed. Sockets 23 are provided between the ribs 22 for clamping with the support frame wall 112. During the paving of the curbstone, after the main frame 1 is installed in place and the support frame 111 is filled with sand, the transverse cover plate 2 is covered on the upper end of the bottom support body 11 to form a seal for each support frame 111 to prevent soil or other debris from falling in; the transverse cover plate 2 can also form a relatively uniform support for the curbstone.
[0034] When the curbstone is laid, the bottom support body 11 provides support and leveling for the curbstone. When the width of the curbstone is greater than the width of the bottom support body 11 or the side flat stone or drainage ditch matching the curbstone also needs to provide leveling, such as Figure 4As shown, the curbstone cushion layer assembly in some embodiments also includes a transverse cover plate 3. The transverse cover plate 3 includes a transverse sealing plate 31, and the lower surface of the transverse sealing plate 31 is provided with raised ribs 32, which are surrounded by a frame shape and can be inserted into the support frame 111 to form a fixation, and a socket 33 is provided between the ribs 32 for clamping with the support frame wall 112; the side of the transverse cover plate 3 away from the side support wall 12 (towards the inner side of the roadbed) is provided with an extension 34, and the extension 34 can further increase the support width of the curbstone cushion layer assembly, so as to level the wide-body curbstone, side flat stone or drainage ditch. The extension 34 is composed of a plurality of extension support frames 341 extending along the length direction of the curbstone, and the extension support frame 341 can also be filled with sand or gravel to improve the support stability and the overall strength of the extension. In different embodiments, the extension support frame 341 can be configured as a horizontally extending cylindrical structure, or as a vertically extending cylindrical structure. In a preferred embodiment, the thickness of the extension portion 34 is consistent with the thickness of the bottom support body, that is, after the transverse cover plate 3 covers the upper end of the bottom support body 11, the bottom of the extension portion 34 is basically aligned with the bottom of the bottom support body 11 and can be arranged on the same plane.
[0035] In a preferred embodiment, the combination Figure 1 The top of the reinforcement frame 121 of the side support wall 12 is configured as an inclined surface, which is consistent with the conventional curbstone foundation structure; a corresponding inclined cover plate 4 is configured on the inclined surface to form a top cover for the reinforcement frame 121, such as Figure 5 As shown. The inclined cover plate 4 includes an inclined sealing plate 41, and a protruding rib 42 is provided at the bottom of the inclined sealing plate 41. The rib 42 is surrounded by a frame shape and can be inserted into the reinforcement frame 121 to be fixed. The rib 42 is relatively inclined relative to the inclined sealing plate 41, and the inclination angle matches the inclination degree of the inclined surface at the top of the reinforcement frame 121. The inclined cover plate 4 can prevent dirt and other debris in the green belt from falling into the reinforcement frame 121 during the construction process and after the paving is completed.
[0036] In different embodiments, according to the different specifications of the curbstone to be laid, the curbstone cushion layer assembly can be manufactured into different sizes. In a preferred embodiment, the length of each support frame 111 does not exceed 1 / 3 of the length of the curbstone, so that at least two sections of support frame walls 112 can form support for the curbstone during the paving process of the curbstone, thereby improving support strength and stability. In one embodiment, the overall length of the curbstone is 75cm, and the length of each support frame 111 is 25cm. In certain embodiments, the curbstone cushion layer assembly is pre-manufactured in batches using lightweight materials such as engineering plastics, so as to transport in batches, quickly pave, and reduce construction costs. In a preferred embodiment, the curbstone cushion layer assembly as a whole is manufactured using recycled plastics.
[0037] In a preferred embodiment, the process of paving a curbstone using the curbstone cushion assembly is as follows:
[0038] Clean the paved area of the curbstones at the edge of the roadbed and level the ground;
[0039] The pre-batch manufactured curbstone cushion components are transported to the construction site and paved. The main frames of adjacent curbstone cushion components are arranged end to end. Triangular gaps are reserved between adjacent main frames 1 at the corners and filled with supporting materials, such as wooden wedges or concrete. The side support walls 12 of the main frames are arranged on the outside of the roadbed to separate the road from the sidewalk or green belt outside. The width of the bottom support body 11 extending to the inside of the roadbed is greater than the width of the curbstone.
[0040] The supporting frame 111 and the reinforcing frame 121 of the main frame 1 are filled with sand, and the transverse cover plate 2 and the inclined cover plate 4 are installed, and the ribs 22 and the ribs 42 are respectively clamped in the supporting frame 111 and the reinforcing frame 121 and fixed.
[0041] The curbstone is laid on the curbstone cushion assembly, the bottom support body 11 provides leveling for the curbstone, and the side support wall provides lateral support for the curbstone to prevent the curbstone from falling outward.
[0042] After the paving of the curbstone is completed, the portion of the bottom support body 11 extending beyond the width of the curbstone toward the inner side of the roadbed is continued to be used to provide leveling for the side leveling stone or the drainage ditch to complete the road construction.
[0043] The purpose of the above embodiments is to further explain the present invention in detail in conjunction with the accompanying drawings so that those skilled in the art can understand the technical concept of the present invention. Within the scope of the present invention, the optimization or equivalent replacement of the structure of the parts involved, and the combination of the implementation methods in different embodiments without conflict of structure and principle, all fall within the protection scope of the present invention.
