Description

[0001] The utility model relates to the field of road construction and can be used in the construction and repair of roads and pedestrian sidewalks and in the improvement of adjacent territories.

[0002] A common problem is the erosion of soil along roadsides onto the roadway. Curbs don't always effectively prevent this. On the contrary, over time, erosion in the rock creates a natural channel for soil to wash onto roads and sidewalks. Furthermore, adjacent land is often higher than any existing curbs or kerbs. Excess soil and dirt on public roads not only has aesthetic consequences and creates inconvenience for residents due to dust in the air, but also generates additional costs for utilities, as soil must be collected and removed from city roads.

[0003] Various methods for strengthening and protecting curbs are known from the prior art.

[0004] In particular, a method for curb restoration is known, which includes the following steps: preliminary sealing of cracks and potholes, cleaning and priming of the curb surface, gluing a 2-3 cm thick L-shaped protective strip made of ultra-high-strength cement composite with PVA fiber, followed by joint grouting and sealing.

[0005] A known curbstone overlay, selected as the closest analogue, comprises a molded sheet in the form of an angle having a front and a working surface. The molded sheet has upper, lower, left, and right side edges, wherein the cross-section of the molded sheet is formed to repeat the geometry of the outwardly protruding surface of the curbstone and consists of a horizontal wall, an inclined wall, a front compensator, and a rear compensator, wherein the horizontal wall transitions into the inclined wall, the inclined wall transitions through a bend into the front compensator, and the horizontal wall transitions through a bend into the rear compensator. The working surface is covered with an adhesive layer covered by a protective film that can be removed from the adhesive layer. Russian Patent No. 194029, published November 25, 2019.

[0006] Such solutions are primarily designed for the restoration and protection of existing curbs, restoring their original form and functionality. They also provide an aesthetically pleasing appearance to damaged sections of the road barrier and protect its elements from further deterioration.

[0007] The difference of the declared technical solution, in particular, is the presence of an additional protective barrier located on the edge formed by the upper and back parts of the pad, and forming an obtuse angle with the upper part.

[0008] The objective of the declared technical solution is to improve the protective function of the installed curbstone with the help of a facing overlay by increasing the overall height of the barrier level formed by the curbstone and this overlay.

[0009] The technical result of the claimed solution is to increase the efficiency of the protective function of the curbstone for high-quality isolation of the road surface and sidewalks from the adjacent areas.

[0010] The claimed technical result is achieved due to the fact that the facing overlay for the curb stone contains an upper part for application to the upper edge of the curb stone and a back part for application to the back edge of the curb stone, connected to each other and to a protective barrier located on the edge formed by the upper and back parts of the overlay and forming an obtuse angle with the upper part.

[0011] The protective barrier, located on the edge formed by the top and back of the pad, separates the grass or soil area from the roadway, significantly reducing the amount of dirt, debris, and soil flowing onto the road with meltwater or after rain. Connecting the protective barrier to the top and back of the pad at the junction allows for easy positioning and installation on the curb corner, ensuring maximum protection against particles from the off-road area falling onto the roadway and vice versa, as in this design, the barrier is positioned directly at the level where the curb separates these zones. This prevents the contamination and accumulation of heavy dust and moisture on the curb surface, which would subsequently lead to contamination of the roadway, air pollution, and accelerated deterioration of the curb.

[0012] The protective barrier's placement at the junction of the top and back sections ensures its positioning directly at the dividing line between the lawn and road areas, physically blocking the flow of dirt and meltwater before it reaches the curb. Because the protective barrier is positioned at an obtuse angle to the top (and, correspondingly, at an acute angle to the adjacent surface—lawn or soil, which is, on average, flush with the top of the curb), this design is characterized by sufficient stability. The resulting gently sloping section on the road side is more resistant to sudden impacts—rocks or water ricocheting from cars and flying debris from cleaning equipment. At the same time, the acute angle on the back side is more resistant to gradual soil pressure and reduces the fracture stress of the entire structure, thereby increasing the service life of the barrier and, consequently, the protective function of the pad.In addition, the sharp shape of the corner on the back side more effectively holds the flow of water with dirt, swirling it.

[0013] The preferred angle between the protective barrier and the top is 100-140 degrees. This angle range further enhances the product's protective function. At an angle of less than 100°, the barrier may lose resistance to soil pressure and ricochets, while at an angle of greater than 140°, the barrier may be too flat, reducing its barrier height.

[0014] The connection of the upper and rear parts to each other at a right angle is characterized by maximum stability due to the resulting stiffening rib, corresponding to the rib of the curbstone, eliminating the displacement of the lining relative to the curb with subsequent deformation of its parts, which can lead to a deterioration in the protective function.

[0015] The connection of the upper part with the front part further increases the protective function of the overlay due to the complete overlap of the upper edge and at least part of the front edge of the curb stone, taking into account their adjacent edge, and also further increases the stability and rigidity of the overlay due to the presence of an additional stiffening rib.

[0016] The design of the facing cap, in which the back of the cap is connected with a flat step facing away from the top, ensures simple and secure installation by anchoring the step into the ground. This design allows the flat step to act as a hook, pressed down by a layer of soil, preventing the cap from being removed from the curb by wind, impact, etc., thereby maintaining the cap's protective function under all operating conditions.

[0017] The claimed technical solution is further explained with the help of figures 1, 2, which conventionally show the design options for the facing overlay for the curb stone.

[0018] The numbers on the figures indicate:

[0019] curbstone (1);

[0020] upper part (2);

[0021] back part (3);

[0022] protective barrier (4);

[0023] front part (5);

[0024] flat step (6).

[0025] Next, one of the preferred embodiments of the claimed technical solution is described with reference to the figures.

[0026] The facing overlay for the curbstone (1) (kerb / curb) comprises an upper part (2) for applying to the upper edge of the curbstone (1) and a back part (3) for applying to the back edge of the curbstone (1).

[0027] The upper part (2) and the back part (3) are connected to each other and to the protective barrier (4), located on the edge formed by the upper and back parts (2), (3) of the overlay (at the junction of the parts). The protective barrier (4) forms an obtuse angle with the upper part (2), preferably equal to 100-140 degrees.

[0028] Preferably, the upper part (2) and the back part (3) are connected to each other at a right angle.

[0029] In one embodiment of the overlay, its upper part (2) is connected to the front part (5). The front part (5) of the overlay takes into account the size and shape of the front face of the curbstone (1), including bevels and chamfers.

[0030] The back part (3) can be connected with the bottom side to the flat step (6) facing the opposite side from the top part (2).

[0031] The facing can be made from, but is not limited to, various fiber cement, concrete, ceramic, or plastic materials resistant to the expected load, temperature changes, and weather conditions. For example, low-density polyethylene (HDPE) or suitable grades of polyurethane and polypropylene compounds, as well as mixed polymers made from recycled materials with added PVC, can be used.

[0032] The stated curbstone facing strip (1) can be used as follows.

[0033] The facing strip is installed on the curbstone (1) facing the land / lawn side. The top (2) of the strip is positioned on the upper edge of the curbstone (1), while the back (3) is applied to its back edge, and the protective barrier (4) separates the road area from the lawn along the height of the barrier (4).

[0034] A facing strip with a frontal section (5) and a flat step (6) (Fig. 2) is more resistant to roadway loads and external factors (flying stones, water jets from sprinklers, and sweeper brushes). This design can be used for major repairs of damaged sections of road curbs with minimal labor. If made from the hard materials listed above, it can be set with mortar or adhesive, creating a secure connection.

[0035] A facing overlay in a minimal design, without a front part (5) and a flat step (6) (Fig. 1), can be used in pedestrian areas and private areas, as well as on public roads without increased requirements for stability, for example, private sectors or courtyards of residential complexes where there are no watering machines and traffic speeds are not high.

[0036] Both options can be used without changing the design of the road structure and without damaging the existing road surface and curbstone installed there (1).

[0037] The facing overlay may be provided with holes for permanent fastening to the curb stone (1) with dowels or pins into the soil (in this case, the holes are located in the flat step (6) of the overlay).

[0038] If the material from which the facing plates are to be made and its thickness allow, the facing plates can be installed overlapping, with a slight overlap, which makes the entire chain sequentially connected and helps to increase the stability of each lining in the event of a point impact on one of them or its extrusion. In this case, at the junction (overlap) of the facing plates, at the intersection of the upper and rear sides, close to the base of the protective barrier (4), a cut is made in the next and / or previous plate (preferably in the rear part (3) at the point next to the connection with the protective barrier (4) and the transition to the upper part (2)), into which they are joined; or these "cuts" can be provided during production at the manufacturer's factory according to the order and specifications of the customer. In this way, the lining plates can be connected in series with the locking clutch element.

[0039] It is also possible to install them end-to-end, providing a gap and adding a connecting element to the structure for connecting them to each other (similar to garden borders).

[0040] When using solid materials (concrete, ceramics), installation is carried out end-to-end, ensuring the necessary technical gap.

[0041] In addition to its primary protective function, this curbstone can also serve as a color-coded marker for specific areas, allowing for the complete restoration and augmentation of damaged and sunken road curbs without the need for major reconstruction of all adjacent road elements or resurfacing. It can also serve as a safe barrier and visual zoning element to prevent parking in areas not intended for this purpose.

[0042] The presented figures, description of the design, and use of the facing overlay do not exhaust the possible design variations and do not in any way limit the scope of the claimed technical solution. Other design variations are possible within the scope of the claimed formula.
