Description

Technical Field

[0001] This utility model relates to the field of precast concrete curbstone technology, specifically to a high-performance precast concrete curbstone. Background Technology

[0002] Curbstones are a crucial road infrastructure, referring to stone objects located at the edge of roads. Their function is to separate roads from sidewalks and protect the underlying structures, drainage systems, and power lines. In the process of urbanization, with the gradual improvement of transportation infrastructure, the primary function of curbstones is to separate roads from sidewalks, preventing water accumulation and traffic accidents. Currently, the common construction method for curbstones involves constructing the base layer after the road structure layer is completed. The base layer has pre-reserved installation positions for the curbstones. After the base layer is finished, grooves are cut to install the curbstones. After installation, backing concrete is poured on the outside of the curbstones, thus securing them to both sides of the road.

[0003] Existing technologies, such as the prefabricated assembly drainage structure for municipal roads disclosed in CN110863407A, achieve the functions of water collection, drainage, and curbstone installation by setting functional parts such as flow channels, spigots, sockets, water inlets, and curbstone pre-reserved grooves on the main body of the structure. However, the shortcomings of this structure are that its integration is too high and there are too many functional parts. When producing this structure, the requirements for molds and production processes are high, which will inevitably increase the production cost. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-performance precast concrete curbstone, which can reduce the production requirements and production costs of curbstone, and at the same time facilitate the subsequent construction and assembly of curbstone.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance precast concrete curbstone, wherein the precast concrete component is specifically a precast concrete curbstone, including a top seat and a base. The lower end of the top seat is provided with an upper groove; the lower end of the top seat body is also provided with a connector, and the top seat body is fixedly mounted on the base through the connector; the upper end of the base is provided with a lower groove that cooperates with the upper groove to form a flow channel; the top seat is also provided with a water inlet communicating with the flow channel.

[0006] Preferably, the upper end of the base is provided with a mounting groove; after installation, the connector is located in the mounting groove, and the lower end face of the top seat body abuts against the upper end face of the base; at least part of the dimensions of the connector are adapted to the dimensions of the mounting groove.

[0007] Preferably, the connector includes a limiting seat; the limiting seat is fixedly disposed at the lower end of the top seat body; the periphery of the limiting seat is in seamless contact with the inner wall of the mounting groove.

[0008] Preferably, the connector further includes a plurality of threaded steel bars fixedly disposed at the lower end of the limiting seat; the plurality of threaded steel bars are distributed along the length direction of the limiting seat.

[0009] Preferably, the water inlet has a teardrop-shaped structure that is narrow at the top and wide at the bottom.

[0010] Preferably, there are several water inlets; the several water inlets are distributed along the length direction of the top seat body.

[0011] Preferably, the left end of the base is provided with a plug protruding from the base body; the right end of the base is provided with a receiving groove that can be inserted and matched with the plug; both the plug and the receiving groove correspond to the lower groove.

[0012] Preferably, both the insert and the receiving groove are U-shaped structures.

[0014] Preferably, the lower end of the base is provided with a serrated groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by producing and matching top seats and bases separately to form a curbstone, the assembled curbstone can form an integrated structure.

[0021] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0022] See Figure 1-4 In one embodiment of this utility model, a high-performance precast concrete curbstone is provided. The precast concrete component is specifically a precast concrete curbstone. A single curbstone includes two parts: a top seat 1 and a base 2. The top seat 1 can be installed on the base 2. This curbstone not only ensures the traffic safety of pedestrians and vehicles, keeps the road edge neat, and prevents soil erosion, but also has the functions of water collection and drainage. During production, the top seat 1 and the base 2 are precast using different molds. The simple structure not only facilitates production but also reduces production costs.

[0023] Specifically, the top seat 1 has a rectangular parallelepiped structure, with a downward-facing upper groove 11 at its lower end. The upper groove 11 has a U-shaped structure. The front end of the top seat 1 has two water inlets 12 distributed along the length of the top seat 1, and both water inlets 12 are connected to the upper groove 11. The lower end of the top seat 1 has two strip-shaped limiting seats 13, which are symmetrically arranged on both sides of the upper groove 11. Each limiting seat 13 has several threaded steel bars 14 along its length, and the threaded steel bars 14 are perpendicular to the lower end face of the top seat 1.

[0024] In one embodiment, the number of inlets 12 is not limited to the two mentioned above, and can be increased or decreased according to actual conditions.

[0025] The base 2 has a rectangular parallelepiped structure with a downward-facing lower groove 21 at its upper end and an upper groove 21 in a U-shape. Two mounting slots 24 are located on either side of the lower groove 21 at the upper end of the base 2. When the top seat 1 is installed on the base 2, the upper groove 11 and lower groove 21 form a complete flow channel. At this time, two limiting seats 13 are correspondingly positioned within the mounting slots 24, with the outer periphery of the limiting seats 13 seamlessly connected to the inner wall of the mounting slots 24. It can be understood that the cooperation between the limiting seats 13 and the mounting slots 24 serves a positioning function, facilitating the installation of the top seat 1 on the base 2 and improving construction efficiency. Additionally, a threaded steel bar 14 is located within the mounting slots 24. During construction, an appropriate amount of fine aggregate concrete is first poured into the mounting slots 24. After curing, due to the action of the threaded steel bar 14, the top seat 1 and the base 2 are integrated to form a curbstone.

[0026] In one embodiment, in order to allow water inside the channel to seep down through the gaps between the curb stones, the left end of the base 2 is provided with an insert 23 protruding from the body of the base 2; the right end of the base 2 is provided with a receiving groove 22 that can be inserted and matched with the insert 23; both the insert 23 and the receiving groove 22 correspond to the lower groove 21, and therefore, both the insert 23 and the receiving groove 22 are U-shaped.

[0027] In the typical process of curbstone construction, the curbstone trench is first excavated, and then a sand cushion layer and fine stone concrete are laid at the bottom of the trench. After the concrete is poured, the surface of the cured concrete is roughened to improve the stability of the curbstone foundation. This process is relatively complicated. Therefore, in one embodiment, in order to improve the contact surface between the curbstone and the concrete foundation, a serrated groove 25 is provided at the lower end of the base 2.

[0028] In one embodiment, the inlet 12 is a teardrop-shaped structure that is narrow at the top and wide at the bottom. The advantage of this structure is that when water flows into the channel from the inlet 12, the water flow at the bottom is large but the height is low, while the water flow at the top is high but the flow rate is small. Overall, this makes the scouring force of the water flowing into the channel on the inner wall of the channel smaller, which can improve the erosion resistance of the curb.

[0029] This technical solution uses separately produced and compatible top and base components to assemble a curbstone, which can form an integrated structure. This curbstone not only ensures the traffic safety of pedestrians and vehicles, keeps the road edge neat, and prevents soil erosion, but also has the functions of water collection and drainage. Prefabricating the top and base components using different molds not only facilitates production but also reduces production costs.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
