Description

Technical Field

[0001] This utility model relates to a concrete curbstone, specifically a lightweight prefabricated fiber-reinforced hollow curbstone. Background Technology

[0002] The rapid pace of urbanization has led to a continuous expansion of urban road construction, making curbs, as a key component of the road system, increasingly important. Curbs not only provide clear road boundaries and ensure the safety of vehicles and pedestrians, but also play a vital role in urban landscaping and are an indispensable part of urban infrastructure construction.

[0003] Currently, the market offers a wide variety of curbstone materials, including granite, natural stone, and concrete curbstone. While granite and natural stone are aesthetically pleasing and durable, their heavy weight and high cost have led to concrete curbstone gradually gaining a larger market share. However, the widely used traditional concrete curbstone often suffers from damage, peeling, cracking, and breakage during long-term service, severely impacting the aesthetics and safety of roads. Its strength and durability are insufficient to meet the dual challenges of high-load modern traffic and complex climate changes, failing to guarantee the long-term stable operation of urban roads.

[0004] Therefore, it is necessary to develop a new type of curbstone to reduce the weight and cost of use of existing curbstones while improving their strength and durability. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength hollow concrete curbstone to solve the problems of existing curbstones being heavy, costly, and lacking in strength and durability.

[0006] To achieve the above objectives, this utility model provides a lightweight prefabricated fiber-reinforced concrete hollow curbstone, comprising: a rectangular strip-shaped body with at least one long side having a chamfer, and at least one cylindrical hollow space provided within the body along the strip direction. The body is cast with self-compacting concrete, and the curbstone has a room-temperature vitrified layer on its outer surface.

[0007] The hollow curbstone using this utility model has the following technical features: Because a room-temperature vitrified layer is provided on the surface of the curbstone, the surface of the curbstone is more beautiful and robust, and the surface is less prone to peeling, cracking, or detachment. Because the hollow space is set along the length of the body, not only is the weight of the curbstone reduced, thus lowering costs, but the hollow structure also facilitates handling and hoisting, making installation simpler and easier. More importantly, after splicing, the curbstone can form internal channels, which can be used for drainage or pipeline installation.

[0008] As a preferred embodiment, for the purpose of facilitating drainage, the hollow space is a quadrangular prism or a cylinder, and the chamfer of the main body is provided with water-permeable holes, which are connected to the hollow space.

[0009] As a preferred option, in order to ensure the aesthetics of hollow curb stones, the curb stones located at the ends have an opening in the hollow space located at the bottom or rear of the curb stone.

[0010] As a preferred embodiment, the hollow space is provided in two parts, one above the other.

[0011] As a preferred embodiment, in order to facilitate the flow of rainwater into the hollow space, the angle of the permeable holes gradually tilts downward from the outside to the inside.

[0012] As a preferred option, in order to further reduce the cost of the curbstone, the room temperature ceramic layer is applied to the front side, top surface and chamfered surface near the drainage hole.

[0013] As a preferred option, in order to facilitate the installation of pipelines in the curbstone, the hollow space is trough-shaped, and the inner wall of the trough is provided with ridges.

[0014] As a preferred option, a support plate is installed at the bottom of the groove of the curbstone to ensure the overall strength of the curbstone. Attached Figure Description

[0019] These include: body 1, room temperature ceramic layer 11, chamfer 2, hollow space 3, edge 31, water-permeable hole 4, and support plate 5. Detailed Implementation

[0020] The following detailed description, in conjunction with the accompanying drawings, illustrates the specific embodiments:

[0021] Example 1

[0022] like Figure 1 and 2As shown, this embodiment provides a lightweight prefabricated fiber-reinforced concrete hollow curbstone, including a rectangular strip-shaped body 1 with at least one long side having a chamfer 2. At least one cylindrical hollow space 3 is provided within the body 1 along the strip direction. In this embodiment, one hollow space 3 is provided. The width of the curbstone body 1 is greater than 22 cm, allowing for installation without a backrest. The curbstone body 1 is cast from self-compacting concrete. A room-temperature vitrified layer 11 is provided on the surface of the curbstone. The concrete used has a grade of C80 or higher, which has high strength, allowing the component to be lighter and thinner while meeting strength requirements. By providing the room-temperature vitrified layer, the surface of the curbstone becomes more robust and less prone to peeling, cracking, flaking, or damage. The room-temperature vitrified layer 11 is provided on the front side, top surface, and chamfered surface near the curbstone body. The room-temperature vitrified layer 11 is achieved by applying a Dolan impregnated enamel material to the surface of the concrete hollow curbstone. Specifically, firstly, the surface of the hollow concrete curbstone is thoroughly cleaned to remove impurities and oil stains, and then a sealing primer is applied to enhance adhesion. Next, it is sanded smooth, and a porcelain-coating primer and topcoat are sprayed onto the front, top, and chamfered surfaces of the hollow curbstone to form a porcelain enamel coating. After construction, timely spray curing is performed to achieve a room-temperature porcelain layer. The hollow space 3, set along the length of the curbstone body 1, is a quadrangular prism or cylinder, which reduces the amount of concrete used and facilitates handling and hoisting. Furthermore, the internal channels formed after the curbstone is assembled can be used as drainage channels. Water-permeable holes 4 are set on the chamfered corners of the curbstone body, communicating with the hollow space. The angle of the water-permeable holes 4 gradually decreases from the outside to the inside to facilitate rainwater inflow. An opening in the hollow space of the inclined curbstone at the end is located at the bottom or rear of the curbstone, allowing water to be easily introduced into the sewer from the rear or bottom.

[0023] Example 2

[0024] like Figure 3 As shown, the hollow curbstone in this embodiment has a basically the same structure as that in embodiment 1. The difference is that the hollow space of the hollow curbstone is groove-shaped, and the inner wall of the groove is provided with ridges 31 to strengthen the strength of the hollow curbstone. At the same time, in order to ensure the overall strength of the curbstone, a support plate 5 is also provided at the bottom of the groove of the curbstone. The support plate 5 is snapped into the groove of the hollow curbstone body 1, thereby forming a detachable hollow space 3. This hollow space 3 is used to arrange pipelines. This detachable structure can keep the lower support plate and pipelines intact when replacing the damaged hollow curbstone, and only the upper groove-shaped curbstone is replaced.

[0025] Example 3

[0026] like Figure 4As shown, the hollow curbstone in this embodiment has a basically the same structure as that in embodiment 1. The difference is that the hollow space of the hollow curbstone is cylindrical, there are two hollow spaces, and they are distributed parallel to the long side of the hollow curbstone. The long side of the hollow curbstone facing the road surface is provided with a rounded chamfer.
