Description

Field of technology to which the invention relates The claimed invention relates to the field of road or municipal construction, and concerns the design of a support device, the upper part of which is designed to accommodate curb blocks, stones or other decorative elements, mounted with the possibility of their subsequent quick replacement. With the help of such supporting devices, joined at the ends, fencing strips, dividing or decorative strips are formed. The claimed technical solution can be used in the creation of border barriers for roads, sidewalks, lawns, flower beds, patios, garden paths, sports and other grounds, performing the function of strengthening the edges of the fabric of these structures and providing the possibility of their decorative design, while the supporting device for border elements can simultaneously carry out the function of draining water runoff from roads, sidewalks and other objects bordered with the help of the inventive device, and also serve as structures for laying cables and other communication lines.

State of the art

To improve the stability and strengthening of sidewalks and similar structures, curb blocks, either made from natural stone such as granite or concrete curbs made from compressed concrete, are used as edge elements. In order for the curb fence to be fixed in relation to the ground, and also to prevent displacement of its component parts in relation to each other, these blocks are fixed with concrete. In such fences it is impossible to replace a specific damaged block, and, as a rule, repairs are carried out either by completely replacing the curb structure or a significant section of it.

Technical solutions are aimed at solving this problem, in which curb fences are made of two parts, of which the lower part of the structure is fixed with concrete in the ground, and the upper part, which performs dividing and decorative functions, is installed on top and fixed using a quick-release connection.

The design of a curb fence is known (see description of patent SU No. 1318625, publ. 06.23.87), in which the curb stone is made of a lower part buried in the ground and an upper part located above ground level, which forms the actual curb. These lower and upper elements are connected by an anchor adjustable in length, passed through coaxial holes made in the stone elements. If the upper part is damaged, it is replaced with a new one, while the lower part remains intact and the remaining elements of the curb structure are not damaged, i.e. The above invention solves the problem of maintainability.

The disadvantage of this solution is that the fastening element is visible on the surface of the upper element, which is undesirable for a product that performs a decorative function.

There is a known solution for a device intended for edging the edges of a sports field (see the description of the patent document DE 2430000 (A1), published on September 11, 1975), characterized by the presence of a decorative strip with a rectangular cross-section, connected to the supporting part by means of snap elements. The supporting part is made in the form of pipe sections spaced along the edges of this platform, buried in the ground and concreted, to the upper ends of which a U-shaped profile is bolted. The bottom part of this profile has protrusions that increase the rigidity of the profile and provide a gap for ventilation between the bottom part of this U-shaped profile and the decorative strip, which reduces the risk of destruction of the decorative strip. Since the bolts connecting the U-shaped profile with the pipe sections are covered with a decorative strip, such a connection does not deteriorate the appearance of the fence as a whole, as this is the case in the design of the previous analogue. However, such a solution is inferior in performance to a border fence formed from individual blocks, since if the decorative strip is damaged, it needs to be replaced in a significant area of the described edging of the edges of the site.

A known curb fence is formed from blocks mounted on wide concrete supports (see description of patent document KR 20090105377, published 10/07/2009). These supports have a U-shaped notch on the outer surface to accept the curb block. The part of the support buried in the ground is made shaped, with X-shaped longitudinal sections, while through holes are formed in the body of the support, which can form channels running along the curb, used for laying, for example, cables, as well as for forming a drainage system for drainage .

The disadvantage of the above-described technical solution is that a curb fence of this design will only be reliably installed with a very massive support and made of concrete. But even with a large mass, due to the fact that the support is buried in the ground to a height less than the height of the curb block, there is a high risk that, for example, rain flows will weaken the adhesion of the support to the ground, and this can lead to the destruction of the curb in in general.

As a prototype of the proposed solution, the design of a support device for curb elements, namely a profile for edging lawns, disclosed in the description of patent application DE 102020120556 (A1), publ. 02/10/2022, characterized by a number of design features similar to the essential features of the proposed technical solution. The specified prototype is characterized by the presence of a supporting part that ensures fixation of the profile in the ground, i.e. which is the base, and a receiving part located orthogonally with respect to this base, made in the form of a gutter, the cross section of which corresponds to the shape of the curb block placed in it. There are holes in the bottom of the gutter to drain water. These design features are common to the design features of the proposed device.

At the same time, in the known solution adopted as a prototype, the base of the profile is made in the form of a vertically oriented and extended parallelepiped, in the volume of which there are longitudinal and parallel channels that can be used for laying communications, for example, cables. The specified base in the shape of a narrow parallelepiped supports the gutter with curb blocks along the entire length of the gutter, but only in its central part, i.e. the peripheral sections of the gutter are unsupported. Uneven distribution of the load from the weight of the curb stone during the operation of the structure can lead to a skew of the vertical position of the parallelepiped, and, therefore, when connecting the profile with curb blocks into a solid curb fence, there is a risk that the upper surfaces of the curb blocks will be at different levels, or with tilt, which significantly reduces the decorative properties of the fence.

Disclosure of the invention The technical result of the claimed invention is to increase the stability and stability of the position of structural elements during its operation, while the device is characterized by lower material consumption, which leads to a reduction in product costs.

The specified technical result was achieved due to the fact that in a support device for curb elements containing a gutter with holes for water drainage, and a base buried in the ground adjacent to its outer bottom surface, supporting the gutter longitudinally along its entire length, according to the claimed invention, the specified base is made in the form of a pair of vertically oriented panels, spaced across the width of the gutter and rigidly connected to each other. To the greatest extent, the technical result is achieved when the panels are spaced apart from each other at a distance of at least half the width of the gutter, while each panel is spaced from the longitudinal axis of symmetry of the gutter by no less than part of its width.

Rod elements can be used as connections between vertical panels, discretely connecting the surfaces of these panels facing each other. However, the preferred option for implementing rigid connections between the panels are longitudinal strips or plates, the width of which is selected depending on the distance between the surfaces of the vertical panels facing each other and the placement of the corresponding connecting plate fixed with the longitudinal edges on the mentioned surfaces. In this case, the base structure is more stable, and the spaces between the slats (plates) form longitudinal channels for placing communications.

In one of the embodiments of the proposed device, the plates between the panels are placed at an angle relative to them and are made crosswise in pairs. In another embodiment, the plates are placed between the panels orthogonally to their surfaces and parallel to each other.

It is preferable to make a device with protrusions at the bottom of the gutter, through which a gap will be formed between the bottom of the gutter and the lower surface of the curb elements (curb blocks), which will have a positive effect on drainage, i.e. will provide the opportunity for water to escape and prevent its accumulation under the curb stone, which could lead to its destruction, and will also ensure ventilation of the surfaces of the blocks, which has a positive effect on their durability.

When implementing the device, it is desirable that the protrusions at the bottom of the gutter are like a continuation of the vertical panels. In this case, an additional technical result appears, namely that the force of gravity caused by the weight of the curb blocks will act directly on the vertical panels, i.e. the load on the bottom of the gutter will be minimal, which promotes optimal uniform redistribution of the load and will have a positive effect on maintaining the integrity of the structure and its durability.

The inventive device can be used with any curb blocks, stones or other decorative elements of various shapes. This application makes it possible to produce the gutter with a different cross-section. In particular, the gutter can be made with shaped cross section, or with shaped cross-section, or with a U-shaped cross-section, or with shaped cross section.

A design feature of the proposed device in its specific implementation is that part of the bottom of the gutter is made with some thickening. This design is relevant mainly for devices with shaped cross-section and with thickening in the area between the protrusions.

The inventive solution allows the use of various options for making holes in the gutter, which can be in its bottom part, or in the side walls, and can be of various shapes, for example, in the form of slots in the side walls of the gutter.

Depending on the nature of the soil in which the inventive support devices for curb elements are installed, these devices can be equipped with additional support plates or similar support elements that increase the stability of the inventive device, in particular with a T-shaped or U-shaped cross-section. It is possible to make the device with fastening elements that penetrate either the base plate or vertical panels, and strengthen the adhesion of the base of the device to concrete when installed on a concrete-gravel pad. For the same purpose, on the inner surface of each panel, along its lower edge, there is a narrow longitudinal shelf, increasing the contact area of the base of the device with the medium that fixes it in a stationary state.

An example of the implementation of the proposed solution

The device shown in the above drawings, which is a support for curb elements, contains a gutter 1 and a base 2 buried in the ground. The gutter 1, depending on the type and shape of the border elements installed in its volume, can be made of various shapes, for example, with shaped, or v-shaped, or U-shaped, or with shaped cross section.

In the presented drawings, the gutter is made with a shaped cross-section intended for curb blocks in the form of rectangular parallelepipeds, which is conventionally shown in Fig. 2.

The base 2 of the device is formed by a pair of vertically oriented panels 3 and 4, spaced across the width of the gutter 1 and interconnected by rigid connections. It has been experimentally established that the device is characterized by the greatest degree of stability when the panels are spaced apart from each other by a distance of at least half the width of the gutter, with each panel spaced from the longitudinal axis of symmetry of the gutter, indicated in Fig. 2 pos. 0, no less than part of the width of this gutter.

In the preferred embodiment of the proposed solution, the rigid connections are made in the form of elongated (longitudinal) plates 5, the length of which corresponds to the size of the vertical panels 3 and 4 at the horizontal level. The longitudinal edges of the plates 5 are fixed on the surfaces of the panels 3 and 4 facing each other. In the space between the panels, the plates 5 can be placed in relation to the surfaces of the panels with an angle and arranged in pairs, and in each pair the plates intersect each other as follows shown in Fig. 1 and fig. 2. A working option is to design a device in which the plates are placed between the panels orthogonally to their surfaces and parallel to each other (see Fig. 5 - Fig. 8, Fig. 10 - Fig. 13). Both in one of the specified designs and in the other, the plates form longitudinal channels 6 in which communication lines can be placed.

In a specific implementation of the proposed device, to improve its performance properties, protrusions 7 are made at the bottom of the gutter 1, thanks to which a gap 8 is created between the bottom of the gutter 1 and the lower surface of the curb element installed in the gutter (conventionally, shown with a dotted line in Fig. 2). Thanks to this gap 8, ventilation of the curb element is ensured, and it also helps to remove water that can enter the volume of the gutter from rain, melting snow, etc. The holes 9 made in the gutter are designed to remove this water. Holes 9 can also be made on the sides of the gutter (see Fig. 12, Fig. 13), however, it is more effective to make these holes in the bottom part.

It is possible to design the device with the panels 3 and 4 spaced apart in such a way that they are in the same vertical planes as the side walls of the gutter 1. This design of the device is shown in Fig. 12 and fig. 13. In this case, the panels are connected to each other by an additional rigid connection in the form of an additional plate connecting the upper edges of the panels and practically adjacent to the lower surface of the bottom part of the gutter.

The implementation of the base 2 with an additional support element 10 ensures the best fastening of the device in relation to the ground, including when concreting the lower part of the base. The additional support element 10 may be in the form of a support plate, as shown in FIG. 7, either in the form of an elongated stand with a T-shaped (see Fig. 10) or U-shaped (see Fig. 11) cross-section. When the element 10 is formed in the form of a base plate, the device can be provided with fastening elements 11 that penetrate this plate, as shown in FIG. 7, increasing the stability of the device and resistance to shearing influences. The same function is performed by rods 12 (see Fig. 8, Fig. 9), passed through holes made in the lower parts of the panels, as well as narrow longitudinal shelves 13 made on the inner surfaces of the panels (see in particular, Fig. 6), providing the best adhesion between the base and the gravel-concrete cushion.

A curb frame mounted using the inventive device is shown in Fig. 14 and fig. 15.

The inventive device can be manufactured using known technologies and equipment. For example, from metal blanks secured to each other by welding or fasteners. However, it is preferable to manufacture the device from plastic materials by extrusion, similar to the manufacture of plastic profiles. The main criteria when choosing plastic are its strength and rigidity, ensuring the possibility of operation under load caused by the weight of curb blocks and stones, i.e. the product should not lose shape under prolonged exposure. Another necessary requirement for the material is its resistance to changes in temperature, humidity and other weather conditions. Such materials are known and widely used in construction.
