Description

Technical Field

[0001] The utility model relates to the technical field of curb stones, and particularly relates to a curb stone with a UHPC outer shell and a concrete inner core. Background Art

[0002] A curb stone is a stone structure used at the edge of a road, located between the road edge and the road surface. Its main function is to provide boundaries and limits for the road, and at the same time, it also plays a role in protecting the road surface and pedestrians.

[0003] Existing curb stones are usually made by integral casting of concrete or whole stones. Although the curb stones made by integral casting of concrete have relatively low cost, their structural stress performance is poor. Whole stones such as marble have good stress performance, but their prices are expensive. Therefore, in order to comprehensively consider from the aspects of economy and rationality of structural stress, a curb stone with a UHPC outer shell and a concrete inner core is proposed. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a curb stone with a UHPC outer shell and a concrete inner core. The curb stone with a UHPC outer shell and a concrete inner core has a reasonable structural design, good stress performance, less material consumption, low cost, and better comprehensive performance in terms of economy and rationality of structural stress than the integral concrete casting or whole stone type curb stone.

[0005] The technical solution of the utility model is as follows:

[0006] A curb stone with a UHPC outer shell and a concrete inner core, comprising a UHPC outer shell and a concrete inner core. The UHPC outer shell is a "C"-shaped shell composed of a front plate, a top plate and a rear plate, and the concrete inner core is filled in the UHPC outer shell.

[0007] Several rib plates are arranged inside the UHPC outer shell.

[0008] One rib plate is arranged on the inner surface of the top plate, and two rib plates are respectively arranged on the inner surfaces of the front plate and the rear plate.

[0009] The cross-sectional structure of the rib plate is a "T"-shaped structure.

[0010] The length of the curb stone with a UHPC outer shell and a concrete inner core is 1000 mm, the width is 200 mm, and the height is 260 mm.

[0011] The thickness of the front plate, the top plate and the rear plate is 10 mm or 20 mm or 30 mm.

[0012] The horizontal and straight section length of the rib plate is 30 mm, and the width is 10 mm; the vertical section length of the rib plate is 20 mm, and the width is 10 mm.

[0013] The beneficial effects of the present utility model are as follows:

[0014] A UHPC shell and concrete core curbstone disclosed by the present utility model has a reasonable structural design, good mechanical properties, less material consumption, low cost, and better comprehensive performance in terms of economy and rationality of structural stress than integral concrete casting or monolithic stone curbstones.

[0018] The components represented by the reference numerals in the drawings are:

[0019] For the present utility model: 1, front plate; 2, top plate; 3, rear plate; 4, concrete core; 5, rib plate. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] As Figure 1 , the UHPC shell and concrete core curbstone includes a UHPC shell and a concrete core. By setting the shell as a UHPC shell, the overall structural strength is improved, making it have better mechanical properties than ordinary concrete curbstones. At the same time, by making the core an ordinary concrete core, the overall cost is reduced, making it more cost-effective compared to monolithic stones such as marble.

[0021] The UHPC shell is a "C"-shaped shell composed of a front plate 1, a top plate 2, and a rear plate 3, and the concrete core is filled inside the UHPC shell.

[0022] To strengthen the bonding strength between the UHPC shell and the concrete core, several rib plates 5 are provided inside the UHPC shell.

[0023] Specifically, one rib plate 5 is provided on the inner surface of the top plate 2, and two rib plates 5 are respectively provided on the inner surfaces of the front plate 1 and the rear plate 3.

[0024] The cross-sectional structure of the rib plate 5 is a "T"-shaped structure.

[0025] The length of the UHPC shell and concrete core curbstone is 1000 mm, the width is 200 mm, and the height is 260 mm.

[0026] The thickness of the front plate 1, the top plate 2 and the rear plate 3 is 10 mm, 20 mm or 30 mm.

[0027] The length of the horizontal section of the rib plate 5 is 30 mm, and the width is 10 mm; the length of the vertical section of the rib plate 5 is 20 mm, and the width is 10 mm.

[0028] The UHPC shell concrete core curbstone has a reasonable structural design, good mechanical performance, less material, low cost, and better comprehensive performance in economy and structural mechanical rationality than the integral concrete casting or whole stone curbstone.
