Description:
GRASS PAVER PANELS

TECHNICAL FIELD

The claimed embodiments of the grass paver panels refer to industrial and civil construction and relate to the assembled grass pavers designed for strengthening of earth fills, sport venues, sidewalks, drive ways, etc. These modifications of grass paver panels allow staking of the panels to reduce size of the products during storage, transportation and cut down the transportation expenses.

BACKGROUND ART

A variety of grass paver panels is known. Grass paver is known from No. CH686296 (IPC E01C9/00; E01C9/02, publ. 29.02.1996) made of plastic and consisting of hexahedral prismatic cells with holes and bases with holes in the center of honeycomb structure node points. The disadvantage of such solution is absence of possibility of compact stocking of such paver, which increases net volume of the assembly of such products and, as a result, makes it impossible to reduce the volume during transportation, thus affecting increase of transportation expenses.

Grass paver is known according to US patent No. 6779946 (IPC E03F1/005, publ. 31.08.2000) having a porous structure in the plan and consisting of quadrihedral cells with plane edges and provided with panel joining fasteners around the perimeter. Fasteners for joining of adjacent panels are provided on side face of the panel in the form of longitudinal vertical notches with profile in the form of dovetail and projections corresponding thereto. Half of the cells arranged chequerwise in the panel have no floor and all side edges have holes. Design of this panel allows good growth of roots in horizontal direction and worsens growth thereof in vertical direction. The disadvantage of such solution is absence of possibility of compact stocking of such paver, which increases net volume of the assembly of such products and, as a result, makes it impossible to reduce the volume during transportation, thus affecting increase of transportation expenses. Design of the grass paver panel (patent No. 2280118; IPC E01C5/00; E01C5/20, publ. 20.07.2006) is taken as the closest prior art to the claimed variants of the panels. The panel has a cellular structure in the plan consisting of quadrihedral cells, wherein each edge of the cells has a shape of space harmonic in the plan with a length equal to or divisible by the harmonic half cycle and with a zero amplitude in the joining rib of adjacent cells, and provided with panel joining fasteners and support points around the perimeter, cell edges projecting around the perimeter are connected to one another radially by pairs, support surfaces of the panel are designed in the form of discs with centers compatible with the centers of connection ribs of adjacent cells, and panel joining fasteners are arranged on the cell edges projecting around the perimeter next but one with offset in relation to one another on the opposite side faces of the panel, on which limiting projections of longitudinal and transverse movement under the projecting edges of adjacent cells of adjacent panels are arranged. Design of this panel ensures increase of operational performance of the panel, in particular, increase of durability thereof and ease of assembly of extended reinforced ground coats.

Disadvantage of this grass paver panel may include impossibility of compact stocking during storage and transportation thereof, since it does not provide staking of the panels to their full height structurally. In addition, design of this panel does not allow good growth of roots in horizontal direction, since edges of the structure cells are solid preventing growths of plants in intercellular horizontal direction.

DISCLOSURE OF INVENTION

Technical result of the claimed grass paver panel is a possibility of reduction of the product assembly volume during stocking thereof cutting down the transportation expenses. Technical result may also include provision of packing stiffness of the products on a pallet decreasing defects during storage and transportation thereof. Also, additionally, technical result is an assurance of roots growth in horizontal direction.

Technical result is achieved by the fact that panel according to the first embodiment has a cellular structure, consists of the cells with coupled edges and is equipped with support points made on the lower end face of the panel. New feature in the grass paver panel design is the fact that the apertures with a width exceeding the edge thickness are made in the middle part of the cell edges or on the top, wherein support points in the plan have a profile that may be fitted in the internal profile of the cells.

It is advisable to arrange the apertures on the cell edges to a height from 1/5 to 4/5 of the cell edge height. Preferably, they are arranged to a height of 1/2 of the cell edge height. Height of apertures of less than 1/5 of the cell edge height insignificantly reduces the product stocking volume and height of apertures of more than 4/5 of the cell edge height, in case of insufficient thickness thereof, may reduce stiffness of the panels during formation of grass paver therefrom.

Preferably, apertures are arranged in the bottom in order to ensure root growth in horizontal direction and maintenance of strength of the grass paver on the top during use. Provision of relieving points in the area of aperture floor, for example, in the form of discs, ensures stiffness of packing of the panels on a pallet and protects them against possible damage during storage and transportation, as well as increases reliability of panel fastening in the ground during use.

At the same time, the grass paver panel may consist of quadrihedral cells, for example, may be of square or rectangular shape in the plan. As a special case, each panel cell edge may have a space harmonic shape in the plan with a length equal to or divisible by the harmonic half cycle and zero amplitude in the joining rib of adjacent cells. Support points arranged in the joining area of the adjacent cell edges may have random shape and sizes including: disc, square, hexagon, ellipse, and other profiles, provided that they may be fitted in the internal profile of the cells. Support points for such panels may be, for example, in the form of discs with the centers attached to the centers of joining ribs of adjacent cell edges.

The grass paver panel may also consist of hexahedral cells, for example, in the form of honeycombs. Support points, just like for quadrihedral cells may have random shape and sizes including: disc, square, hexagon, ellipse, and other profiles, provided that they may be fitted in the internal profile of the cells. As a special case, support points may be in the form of discs with the centers attached to the centers of joining ribs of adjacent cell edges. Support points may also be in the form of elliptic plates arranged on the edges parallel to the end surface of the panel with larger axis extended along the lower end surface of the edge, wherein the apertures are provided on the edges free from support points on the bottom and top.

The grass paver panel may consist of cylindrical cells joined by centerline planes with straight-line edges.

Also, the grass paver panel may consist of cells with different profile alternating with regular spacing, for example, of alternating cylindrical and rectangular quadrihedral cells.

According to the second embodiment, the grass paver panel having cellular structure in the plan consists of cells with coupled edges and floor; apertures are provided in the middle part of the edges on the top to a height of more than 1/2 of the cell edge height and with a width exceeding the edge thickness. Relieving points may be provided in the area of aperture floor, for example, in the form of discs. The panel floor according to the second implementation may be solid. In this case, it is advisable to provide drain holes in the panel floor.

It is advisable to make the grass paver panels monolithic, for example, by means of casting or stamping.

Essence of the invention is explained by the attached drawings intended only for demonstration of the invention implementation examples. The attached examples do not exhaust the possibility of other embodiments of structural design of the grass paver panel characterized in the claims.

Grass paver panel 1 has a rectangular shape in the plan and consists of polyhedral cells 2. Panels 1 are equipped with fasteners 3 around the perimeter for joining of panels 1. Preferably, panel 1 is made monolithic by means of casting or stamping.

In special case, it may consist of, for example, coupled hexahedral cells 2. Edges 4 of cells 2 may be plane 4i (Fig. 1, Fig. 2) or may have a space harmonic shape in the plan 42 (Fig. 7, Fig. 8) with a length equal to or divisible by the harmonic cycle with zero amplitude in the joining rib of adjacent cells 2. Panel 1 is equipped with support points 5 arranged on the lower end face of edges 4 of panel 1. Apertures 6 with a width exceeding the thickness of edges 4 are provided in the middle part of cell 2 edges 4 on the bottom. Support points may be in the form of discs 5i in the plan with the centers attached to the centers of joining ribs of adjacent cell 2 edges 4. Radius of discs 5i is selected from calculation of possibility of arrangement thereof in the internal profile of cells 2. It is advisable to provide the relieving points 7 in the area of aperture 6 floor, for example, in the form of discs of small diameter.

Panel 1 may consist of coupled hexahedral cells 8. Support points 5 may be in the form of discs 5i with the centers attached to the centers of joining ribs of adjacent cell 8 edges 4. Support points may also be in the form of elliptic plates 52 arranged on the edges 4i parallel to the end surface of the panel with larger axis extended along the lower end surface of the edge 4i

The grass paver panel may consist of cylindrical cells 9 joined by centerline planes with straight-line edges 10. Also, the grass paver panel may consist of alternating cells with different profile, for example, of alternating cylindrical cells 9 and rectangular quadrihedral cells 11.

MODES FOR CARRYING OUT THE INVENTION

Stocking of the grass paver panels may be performed as follows: sequential staking of the panels (mounted on one another). Upper panel b is placed in lower panel l i by moving it in horizontal direction in relation to power panel 11 in such a way that support points 5 of upper panel h is arranged inside cells 2 of lower panel l i. Offset of panels in horizontal direction does not exceed half of cell 2 width.

It is advisable to make apertures 6 in panels 1 in the bottom of edges 4 thereof (Figs. 3, 5, 10, 17, 22). In this case, apertures 6 of edges 4 of upper panel I2 are aligned with edges 4 of lower panel l i and upper panel I2 is moved downwards until edges 4 of lower panel li into relieving points 7 arranged in apertures 6 of upper panel 12. Thus, each following upper panel I2 is placed on the lower panel l i with sequential offset in horizontal direction towards side faces alternatively.

If apertures 6 in panels 1 are provided on the top of edges 4, then edges 4 of upper panel 12 are inserted into apertures 6 of lower panel li and upper panel 12 is moved downwards until its edges 4 into relieving points 7 arranged in apertures 6 of lower panel 11. Thus, each following upper panel I2 is placed on the lower panel li with sequential offset in horizontal direction towards side faces alternatively. In this case, it is advisable to arrange aperture 6 to a maximum height with provision of maintenance of the mechanical properties of the panels required for transportation and use.

Stocking of the grass paver panels 1 may be performed by other methods: by pairwise placement of panels 1 on one another with offset in horizontal direction as in the second embodiment. In this case, requirement to the necessity of arrangement of support points in the plan in the internal profile of cells is in excess.

If apertures 6 in panels 1 are provided on the top of edges 4 thereof and are not equipped with relieving points, then during placement of the panels apertures 6 of both panels li and I2 are aligned and upper panel I2 is moved until the bottom of apertures 6 thereof is in contact with the bottom of apertures 6 of lower panel li (Fig. 12). If apertures 6 are provided with relieving points 7, then they may be designed in the form of support points at both sides of aperture 6 (not shown) in order to ensure mutual passage of edges 4 of interconnected panels l i and I2. In this case, it is advisable to arrange apertures 6 to a height < 1/2 of the edge height. In case of equal sizes of apertures 6, more tight packing is performed for this type of stocking comparing to the method mentioned above.

Arrangement of apertures 6 on panel 1 cell 2 edges 4 with provision of alignment of support points 5 with internal profile of cells 2 of panels 1 during stocking allows compact stocking of the product assembly, therefore, reducing the assembly volume and increasing the product packing stiffness.

Offset of panels 1 in horizontal direction insignificantly increases storage space of the panels that is substantially compensated by reduction of the height of the stoked panels at the same quantity thereof. It leads to sufficient reduction of the product packing volume.

Relieving point 7 arranged in apertures 6 is used for reduction of load on apertures of paver edges and prevents destruction and deformation thereof during stocking, transportation, as well as maintenance of structural integrity of the grass paver during use.
