Description

Bend curbstone

Technical Field

The utility model belongs to the municipal facilities field, concretely relates to bend curbstone.

Background

The road edge at the corner of an urban road intersection is often more easily rolled or collided by passing vehicles, and particularly, at some intersections with high traffic flow or poor visibility at night, the probability that the road edge stone at the corner is pressed by the passing vehicles is far higher than that of other road sections. At present, in municipal construction, the tradition uses the bend curbstone in road intersection corner, and the majority forms for the stone strip concatenation that has certain radian, and the vehicle is if pressing the curbstone when turning, falls the curbstone of bend department easily, even with the curbstone take the lane of going on, not only influence the city looks, can bring the potential safety hazard for vehicle, pedestrian in addition.

SUMMERY OF THE UTILITY MODEL

The utility model discloses strip bend curbstone steadiness to traditional use in intersection corner is not strong in present municipal construction, is easily by the problem of the past vehicle overwhelming and taking to the road surface, has provided a technical scheme of bend curbstone as follows:

a curved road edge stone comprises a road edge stone main body. The curbstone main part is the concrete prefabricated part, is the flat construction, and one of them side is the arcwall face, and the distance between arc top and the relative limit is not less than 60 cm. In order to ensure that the road edge stone has higher stability, the road edge stone can be manufactured according to the dimensions of arc radius of 2m-15m, arc length of not less than 100cm and thickness of not less than 20 cm.

As a further optimization, the upper surface of the road edge stone in a strip-shaped area close to the arc-shaped edge can be manufactured into a structure with a step-shaped bulge, so that building materials consistent with the surrounding road surface can be conveniently paved on the curve road edge stone, and the curve road edge stone can be more integrated with the surrounding environment in appearance.

As further optimization, the reinforcing steel bars can be implanted into the main body of the curbstone, the strength of the curbstone can be better improved when the number of the reinforcing steel bars is more than 2, and the curbstone is firmer and more durable.

According to the working experience of daily road construction, a research and development unit calculates the road surface conditions of corners of different road sections, the arc radius of the arc surface of the stone along the curve road is selected within the range of 2-15 m, the paving requirements of intersections with various turning radii can be met, and the requirements on stability can be fully met by the sizes of 20cm in thickness, 100cm in arc length and 60cm in width.

Compared with the prior art, the utility model has the advantages that: this type bend curbstone simple structure easily lays, and the thick flat structure of broad compares in the tradition and uses the arc strip shape curbstone in crossing corner more firm. After the test of vehicle rolling and wheel collision, only partial imprint is left on the surface of the road, and the phenomenon of toppling and inclining does not appear, thereby effectively solving the problem that the stone on the road edge of the curve is easy to topple over.

Drawings

Fig. 1 is a schematic structural diagram of a first embodiment of the present invention;

fig. 2 is a schematic structural diagram of a second embodiment of the present invention.

In each schematic: 1. a curb body; 2. an arc-shaped surface; 3. a stepped projection; 4. and reinforcing the steel bars.

Detailed Description

For a better understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings and specific examples.

Example 1:

the curved road edge stone shown in fig. 1 comprises a road edge stone main body 1, wherein the road edge stone main body 1 is a concrete prefabricated member, is integrally in a flat sector shape and comprises an upper surface, a lower surface and four side surfaces. The outer arc length of the sector is 150cm, the arc radius is 3m, the inner arc length is 120cm, the arc radius is 2.4m, the length of two radial straight sides of the sector is 60cm, the lower surface of the curbstone body 1 is a plane, a strip-shaped area, the upper surface of which is close to the edge of the outer arc surface 2 and is 15cm wide, is of a stepped protruding 3 structure, the thickness of the area is 30cm, and the thickness of other areas is 25 cm. When concrete is used for pouring, three reinforcing steel bars 4 are implanted in the radial direction, and deformed steel bars with the diameter of 10mm and the length of 60cm are selected in the embodiment. When the pavement is paved at the turning of the intersection, three pieces of road edge stones are spliced to form a turning angle, the area of the step-shaped bulge 3 is connected with the road edge stones on the straight roads at two sides, and the floor tiles with the same material as the pavement surface of the sidewalk are paved in other areas.

Example 2:

a curved road-edge stone as shown in fig. 2 comprises a road-edge stone main body 1, wherein the road-edge stone main body 1 is a concrete prefabricated member, is in a flat arch shape as a whole, and comprises an upper surface, a lower surface and two side surfaces. Wherein the upper and lower surfaces are planes, and the side surfaces are an arc-shaped surface 2 and a plane. The arc radius of the arc is 2m, the arc length is 3.1m, the side length of the arc straight line is 2.8m, the distance between the top of the arc edge and the straight line edge is 60cm, and the thickness of the curbstone is 30 cm. When concrete is used for pouring, three reinforcing steel bars 4 are implanted into the interior in the direction perpendicular to the straight line side, in the embodiment, deformed steel bars with the diameter of 10mm are selected, the length of the middle deformed steel bar is 60cm, the lengths of the deformed steel bars on the two sides are 30cm, and grains similar to the pavement floor tile patterns are engraved on the upper surface of the road edge stone. When paving, only need lay this type curbstone at crossing corner and can form the turn angle, lay the construction time, curbstone upper surface and adjacent road surface parallel and level.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
