Description

Field of technology

[0001] The claimed invention relates to the field of road or municipal construction, and concerns the construction of a support device, the upper part of which is designed with the possibility of placing curb blocks, stone or other decorative elements, assembled with the possibility of their subsequent quick replacement. With the help of such support devices, joined at the ends, enclosure strips are formed, either separating or decorative strips. The claimed technical solution may find application in creating curb enclosures for roads, sidewalks, lawns, flowerbeds, patios, garden paths, sports and other areas, performing the function of strengthening the edge of the canvas of these structures and providing the possibility of their decorative design, while the support device for curb elements can simultaneously perform the function of draining water flows from roads, sidewalks and other objects enclosed with the help of the claimed device, and also serve as structures for laying cables and other communication lines.Prior art

[0002] To improve stability and strengthen sidewalks and similar structures as edge elements, curb blocks are used, either made from natural stone, such as granite, or concrete curb stones made from compressed concrete. In order for the curb enclosure to be secured in relation to the ground, and also to exclude displacement of its component parts in relation to each other, these blocks are fixed with concrete. In such enclosures it is impossible to replace a specific damaged block, and, as a rule, repair is carried out either by complete replacement of the curb structure, or a significant section of it.

[0003] Technical solutions are directed at solving this problem, in which curb enclosures are made of components from two parts, of which the lower part of the structure is fixed by means of concrete in the ground, and the upper part, performing separating and decorative functions, is installed on top and fixed by means of a quick-release connection.

[0004] A known construction of curb enclosure is known (see description of patent SU No.1318625, publ. 23.06.87), in which the curb stone is made from a lower part embedded in the ground and an upper part located above ground level, which actually forms the curb. These lower and upper elements are connected by a length-adjustable anchor passed through coaxial holes made in the stone elements. When the upper part is damaged, it is replaced with a new one, while the lower part remains untouched and the remaining elements of the curb structure are not damaged, i.e. the above-mentioned invention solves the problem of repair suitability.

[0005] The disadvantage of such a solution is that a fastening element is visible on the surface of the upper element, which is undesirable for a product performing a decorative function.

[0006] A known solution of a device intended for edging sports platforms is known (see description of patent document DE 2430000(A1), publ. 11.09.1975), characterized by the presence of a decorative strip with a rectangular cross-section, connected to the support part by means of interlocking elements. The support part is made in the form of recesses along the edges of this platform, deepened into the ground and concreted pipe sections, to the upper ends of which a U-shaped profile is attached by bolted connection. On the bottom part of this profile, projections are made that increase the rigidity of the profile and provide a ventilation gap 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 by the decorative strip, such a connection does not impair the overall appearance of the enclosure, as this takes place in the construction of the preceding analog. However, such a solution in terms of operational qualities is inferior to curb enclosure formed from separate blocks, since when the decorative strip is damaged, its replacement is necessary on a significant section of the described platform edging.

[0007] A known curb enclosure is known, formed from blocks installed on wide concreted supports (see description of patent document KR 20090105377, publ. 07.10.2009). These supports have a U-shaped recess on the outer surface for receiving the curb block. The part deepened into the ground is made figured, with X-shaped longitudinal sections, while through holes are formed in the body of the support, which can form channels running along the curb enclosure, used for laying, for example, cables, and also for forming a drainage system for water drainage.

[0008] The disadvantage of the above-characterized technical solution is that the curb enclosure of such construction will be reliably installed only with a very massive support and its execution in concrete. But even with a large mass, due to the fact that the support is deepened into the ground to a height less than the height of the curb block, there is a high risk that, for example, rainwater flows will weaken the adhesion of the support to the ground, and this may lead to destruction of the curb enclosure as a whole.

[0009] As a prototype of the claimed solution, the construction of a support device for curb elements is adopted, namely a profile for edging lawns, disclosed in the description of patent application DE 102020120556 (A1), publ. 10.02.2022, characterized by a number of design features similar to the essential features of the claimed technical solution. The specified prototype is characterized by the presence of a support part providing fixation of the profile in the ground, i.e. serving as a foundation, and a receiving part arranged orthogonally relative to this foundation in the form of a groove, the cross-section of which corresponds to the form of the curb block placed in it. In the bottom part of the groove, holes are made for water drainage. These design features are common with the design features of the claimed device.

[0010] However, in the known solution adopted as a prototype, the foundation of the profile is made in the form of a vertically oriented and extended lengthwise parallelepiped, in the volume of which longitudinal and parallel to each other channels are made, which can be used for laying communications, for example, cables. The specified foundation in the form of a narrow parallelepiped supports the groove with curb blocks along the entire length of the groove, but only in its central part, i.e. the peripheral sections of the groove have no support. Uneven distribution of load from the weight of the curb stone during operation of the construction may lead to distortion of the vertical position of the parallelepiped, and, consequently, when connecting the profile with curb blocks into a complete curb enclosure there is a risk that the upper surfaces of the curb blocks will be at different levels, either with an inclination, which significantly reduces the decorative properties of the enclosure.Essence of the invention

[0011] The technical result of the claimed invention is to increase the stability and durability 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 cost.

[0012] The specified technical result is achieved due to the fact that in the device serving as a support for curb elements, containing a groove with openings for water drainage, and a foundation recessed into the ground adjacent to its outer bottom surface, supporting the groove longitudinally along its entire length, according to the claimed invention the specified foundation is made in the form of a pair of vertically oriented panels, spaced across the width of the groove and rigidly connected between each other. To the greatest degree the technical result is achieved when the panels are spaced from each other at a distance of not less than half the width of the groove, with each panel offset from the longitudinal axis of symmetry of the groove by not less than % of its width.

[0013] As connections of the vertical panels, rod elements may be used, discretely connecting the surfaces of these panels facing each other. However, a preferred variant for implementing rigid connections between panels are longitudinal planks, either 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, secured by longitudinal edges on the mentioned surfaces. In this case the foundation construction is more stable, and the spaces between the planks (plates) form longitudinal channels for placing communications.

[0014] In one of the variants of implementation of the claimed device, the plates between panels are placed in relation to them at an angle and made in pairs crossing each other. In another variant the plates are placed between panels orthogonally to their surfaces and parallel between each other.

[0015] It is preferable to make the device with projections on the bottom of the groove, by means of which a gap will be formed between the bottom of the groove and the lower surface of the curb elements (curb blocks), which positively affects water drainage, i.e. will provide the possibility of water exit and exclusion of its accumulation under the curb stone, which could lead to its destruction, and also provide ventilation of the surfaces of the blocks, which positively affects their durability.

[0016] When implementing the device it is desirable that the projections on the bottom of the groove be as if a continuation of the vertical panels. In this case an additional technical result appears, consisting in the fact that the gravity force caused by the weight of the curb blocks will act directly on the vertical panels, i.e. the load on the bottom of the groove will be minimal, which contributes to optimal uniform distribution of the load and positively affects the preservation of the integrity of the construction and its durability.

[0017] The claimed device can be used with any curb blocks, stones or other decorative elements of various forms. Such application conditions the execution of the groove with different cross-sectional sections. In particular, the groove can be made with a rectangular cross-sectional section, or with a V-shaped cross-sectional section, or with a U-shaped cross-sectional section, or with an obtuse-angled cross-sectional section.

[0018] A constructive feature of the claimed device in its specific implementation is the execution of part of the bottom of the groove with some thickening. Such execution is relevant, primarily for devices with rectangular cross-sectional section and with execution of thickening in the zone between the projections.

[0019] The claimed solution allows the use of different variants of execution of openings in the groove, which can be in its bottom part, or in the side walls, can be of different forms, for example, in the form of slots in the side walls of the groove.

[0020] Depending on the characteristics of the ground in which the claimed support devices for curb elements are installed, these devices may be equipped with additional elements that increase the stability of the claimed device with support plates or similar support elements, in particular with T-shaped or 11-shaped cross-section. It is possible to implement the device with fastening elements that penetrate either the support plate or the vertical panels, and strengthen the connection of the device foundation with concrete when it is installed on a concrete-gravel cushion. For the same purpose, on the inner surface of each panel, along its lower edge, a narrow longitudinal groove is made, increasing the contact area of the device foundation with the medium fixing it in an immovable state.Brief description of the drawings

Best variants for implementing the invention

[0022] The device presented in the above-listed figures, which is a support for curb elements, contains a groove 1 and a foundation 2 recessed into the ground. The groove 1, depending on the type and form of curb elements installed in its volume, may be made of various forms, for example, with a rectangular, or with V-shaped, or with U-shaped, or with obtuse-angled cross-section. In the presented drawings the groove is made with a rectangular cross-section, intended for curb blocks in the form of rectangular parallelepipeds (Fig. 2).

[0023] The foundation 2 of the device is formed by a pair of vertically oriented panels 3 and 4, spaced across the width of groove 1 and connected between each other by rigid connections. It has been experimentally established that the device is characterized by the greatest degree of stability when the panels are spaced from each other at a distance of not less than half the width of groove 1, with each panel 3 offset from the longitudinal axis of symmetry of groove 1, designated by position 0, by not less than ¼ of the width of this groove 1 (Fig. 2).

[0024] In the preferred variant of implementation of the claimed solution, 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 in the horizontal level. The longitudinal edges of the plates 5 are fixed on the surfaces of panels 3 and 4 facing each other. In the space between panels 3 and 4, plates 5 may be placed in relation to the surfaces of the panels at an angle and arranged in pairs, with each pair of plates 5 crossing each other (Fig. 1-2). Also, a working variant is the execution of the device, in the construction of which plates are placed between panels orthogonally to their surfaces and parallel to each other (Fig. 5, 8, 10, 13). As with one indicated execution, so with the other, the plates form longitudinal channels 6, in which communication lines may be placed.

[0025] In the specific implementation of the claimed device, to improve its operational properties, projections 7 are made on the bottom of groove 1, thanks to which a gap 8 is created between the bottom of groove 1 and the lower surface of the curb element installed in the groove, conventionally shown by a dotted line (Fig. 2).

[0026] Thanks to this gap 8, ventilation of the curb element is ensured, and also it facilitates water drainage, which may get into the volume of the groove from rain, melting snow, etc. Openings 9 made in groove 1 are intended for removal of this water. Openings 9 may be made also on the side walls of groove 1 (Fig. 12-13), however more effective is the execution of these openings in the bottom part.

[0027] It is possible to execute the device with spacing of panels 3 and 4 in such a way that they become positioned in the same vertical planes as the side walls of groove 1 (Fig. 12-13). In this case panels 3 and 4 are connected to each other by an additional rigid connection in the form of an additional plate 5, connecting the upper edges of the panels, and practically adjoining to the lower surface of the bottom part of groove 1.

[0028] Execution of foundation 2 with an additional support element 10 provides the best fixation of the device in relation to the ground, including when concreting the lower part of the foundation. The additional support element 10 may be made in the form of a support plate (Fig. 7), or in the form of an elongated support with T-shaped (Fig. 10), or with P-shaped (Fig. 11) cross-section. When executing element 10 in the form of a support plate, the device may be equipped with fastening elements 11 penetrating this plate, increasing the stability of the device and resistance to shifting influences (Fig. 7). The same function is performed by rods 12, passed through openings made in the lower parts of the panels (Fig. 8-9), and also narrow longitudinal grooves 13 made on the inner surfaces of the panels (Fig. 6), providing the best adhesion of the foundation and the gravel-concrete cushion.

[0029] The curb enclosure, assembled using the claimed device, is shown in Fig. 14-15.

[0030] The claimed device may be manufactured by means of known technologies and equipment. For example, from metal blanks, fixed between each other by welding, or by fastening elements. However, preferable is the manufacture of the device from plastic materials by extrusion method by analogy with the manufacture of plastic profiles. The main criteria when choosing the plastic mass are its strength and rigidity indicators, providing the possibility of operation under load caused by the weight of curb blocks and stones, that is the product should not lose form under their long-term influence. Another necessary requirement for the material is its resistance to temperature changes, humidity and other weather conditions. Such materials are known and widely used in construction.

[0031] As is obvious to specialists in this field of technology, this invention can be easily developed in other specific forms, without going beyond the scope of the essence of this useful model.

[0032] Moreover, the present variants of implementation should be considered simply illustrative, and not limiting, wherein the scope of the invention is presented by its formula, and it is assumed that it includes all possible modifications and the field of equivalency of the points of the formula of this invention.
