Abstract

The invention concerns a paving stone made in particular of concrete, with an outer, preferably hexagonal, profile whose lateral faces (2, 102, 203) face each other when the stone is laid on the road surface or the like and in the laid position can brace each other at least in sections. The lateral faces (2, 102, 203) of the hexagonal stone (1, 101, 201) are each provided with a bracing pattern (3, 103, 104, 215) which ensures that a reliable seal is created in the region of the gap between hexagonal stones (1, 101, 201). Recess cuts (105, 106) and/or a horizontal peripheral groove (205) can in addition be provided in the lateral faces (2, 102, 203), thereby improving the stability of the join and the tightness of the join against penetrating contaminants in the gap region.

Description

BACKGROUND OF THE INVENTION The present invention relates to paving stones of concrete, in particular for paving traffic surfaces. Preferably, the paving stone has an outer contour forming a hexagon. The sidewalls facing each other in their position on the foundation are provided with support profiles. The support profile extends vertically over at least a portion of the height of a given side surface, and the support profile has at least one profile tooth on each side surface and a complementary receiving space in a cross section. The profile teeth of the adjacent paving stones extend into the receiving spaces of the adjacent paving stones.

A hexagonal paving stone is known from US-A-5,267,810. The sidewalls of this paving stone are provided with support profiles. In combination placement, only sand is introduced into the gap between adjacent paving stones, so that under heavy loads, adverse movement of the stones is possible and harmful substances can penetrate into the subsoil.

German patent application DE-A-33 03 225 discloses a hexagonal paving stone with cams on adjacent surfaces. The cams form an increased permeability gap in the supine position. As a result, the pavement as a whole is unstable at loading and, through the gap, both surface water and harmful substances can penetrate into the subsoil.

It is an object of the present invention to provide a concrete paving stone of the kind described above, which is highly load-bearing and, at the same time, reliably seals in a closed position.

Starting from the concrete paving stone of the kind described above, this object is solved by the sidewalls of the paving stone being provided with at least one circumferential groove for receiving sealing material or a sealing connecting body extending outwardly on the side surface.

The paving stone according to the invention is thus provided with grooves horizontally encircling its sidewalls, which are positioned between adjacent sidewall portions in a deposited position of a plurality of paving stones so that sealing material can be inserted into these spacious extensions of the laying gap and .

At the same time, the groove forming the receiving chamber is lowered so horizontally with respect to the upper side of the paving stones that forms the traffic surface, that, for example, displacements at the edge of the stones or injuries caused by objects penetrating the sealant contained therein is protected in each case by providing reliable sealing of the soil against unintentional seepage, such as oil or the like.

The grooves forming the chambers have any cross-sectional shape. The cost of producing paving stone may be low, especially for trapezoidal or rectangular shapes. Then the paving stones can be produced, for example, by simple casting. The vertical height of the groove in the sidewall, the dimensions of the groove, and the number of grooves in one sidewall may also vary greatly. Thus, paving stones of various construction shapes can be made available and processed into an optically demanding paving position in accordance with the specific requirements of the customers for tight sealing of the pavement.

In a preferred embodiment of the invention, the sealing material, which is formed, for example, by a flexible or plastically deformable plastic strip, can be inserted into a receiving chamber forming a hollow space when the stone is laid. Due to the resilient properties of the sealant, its sealing effect is maintained even under heavy loads on the road surface, as sealing damage in the installation position is ruled out even with a small vertical displacement of stones or invading foreign matter.

A further embodiment of the above-described hexagonal paving stones is provided with sealing joints integrated in the cast stone body, which, when deposited in a plurality of stones, form protruding parts in the vicinity of the side walls. These protrusions extend into the deposition gap, where they can be joined together to form a liquid barrier safety zone.

In combination with the paving stone formed according to the invention, by means of a suitable overlay, the overlapping of the side surfaces avoids the occurrence of point overloads on the upper side of the paving stones, especially when braking and accelerating vehicles. By distributing the pressure on the surface over a plurality of hexagonal stones that are mutually leaning against the profile teeth, it is sufficiently safe to prevent adverse displacements in the laying plane of the stone. This ensures reliable sealing of the traffic surface against uncontrolled infiltrations into the covered soil.

In a preferred embodiment of the invention, the length of the profile teeth is shorter than the height of the hexagonal stones, so that in the laying position of the paving stones, a trough is formed in sections between the overlapping side surfaces. This allows for a reliable and uniformly sealed deposit and is well sealed, for example with jointing compound.

In a further embodiment of the invention, the paving stone is provided with recesses in the support profile. In this way, a combination of paving stones is formed with interlocking side surfaces. Thus, loads, such as horizontal and / or vertical shear or torque, caused by motor vehicle braking and acceleration movements on the upper side of the paving stones can be carried by the pavement joining of the paving stones such that the individual paving stones are overloaded.

The pressure is formed by a series of predominantly hexagonal stones - and by means of a plurality of profile teeth with bevels on it.

- by dividing the paving stone, adverse displacements in the pavement placement plane can be safely ruled out even under increased load, avoiding gap formation caused by the displacement of individual paving stones, thereby preventing the ingress of harmful substances such as oil or the like into the covered soil can be inhibited.

Figure 1 is a plan view of the paving stone 1 according to the invention formed as a hexagonal stone. The regular hexagonal shape of the paving stone 1 has side surfaces 2 of the same length B. The leaning side surfaces 2 of this hexagonal paving stone 1 in the combined position (Fig. 5, Fig. 6) are provided with a support profile 3, which advantageously enhances the stability of the paved pavement.

In the preferred embodiment, the trapezoidal profile teeth 4, 4 'are formed on each of the side surfaces 2 as a support profile 3 on the hexagonal paving stone 1. Between these profile teeth 4, 4 ', a receiving space 5 is omitted.

In the laying position (Fig. 5, Fig. 6), the vertical toothed profile teeth 4,4 'are evenly distributed over a given side surface 2 such that there are two profile teeth 4,4' on the side surfaces 2 to which two 5,5 ' a receiving space is assigned.

The hexagonal paving stone 1 can be laid into the composite pavement in any position of rotation about its center axis 6 in height. For this purpose, each side surface 2 is preferably provided with a first profiled tooth 4 starting directly from one of its vertices 8, and a second profiled teeth 4 'clockwise thereafter. The profile teeth 4, 4 'have the same distance' A '. However, the profile teeth can also be arranged mirror-like. The profile teeth 4 and 4 'are then positioned counterclockwise starting from the tip 8.

The section of Figure 2 illustrates that the longitudinal extent of the profile teeth 4, 4 'is equal to the height H of the hexagonal paving stone 1. Instead, the hexagonal paving stone 1 is, as in Figures 3 and 4

In a second embodiment according to US 220 681 B1, it may be provided with profile teeth 14, 14 'which terminate below the upper surface 9 of the hexagonal paving stone 1 which serves as a useful surface. Thus, the profile teeth 14,14 'have a height H' greater than the height H 'of the side surfaces 2,2', which, when connected (Figs. 9, 10), allows the profile teeth 14, 14 'to be covered by The page has only a regular hexagonal basic shape.

Fig. 2 shows that the profile teeth 4, 4 'have a chamfer 10 at the transition to the upper side 9 of the hexagonal paving stone. The transition portion of the side surfaces 2, 2 'at the receiving member 5, 5' may also be provided in a convenient configuration with a chamfer 10 '. According to Fig. 4, a slope 11 is formed on the upper side of the profile teeth 4,4 'in height H', which in the combined position (Fig. 6) forms a trough 12 on the bottom side.

In the laying position shown in Fig. 5, the upper side 9 of the leaning hexagonal paving stones 1 forms a substantially flat usable surface, which only creates a gap 13 at the upper edge 10.

7 and 8 illustrate possible variants of the paving stone 1 described above. Accordingly, it is possible to increase the paving stone 1 by constructing the support profile 3 and its regular arrangement, i.e. forming the paving stone Γ and 1 ”according to Figures 7 and 8, respectively. It can be triangular and any rectangular or polygonal shape.

Fig. 9 and Fig. 10 are sectional views of each of the corresponding pair of profile teeth 4,4 'and 14,14', respectively! positions, different configurations of both the gap 13 and the trough 12. The laying trough 12 can be closed with a sealing material in the installation position of the paving stones so that a reliable sealing is achieved by the uniform joint clearance distance (e.g. 10-15 mm) between the stones and is not significantly affected by heavy loads on the upper side 9.

11-22. Figures 1 to 5 show, by way of example, further embodiments of the hexagonal paving stone 1. These figures show the various geometric outlines of the profile teeth 4, 4 'and 14,14'. Also not shown is a possible triangular outline of the profile teeth 4, 4 'and 14, 14'. 17-22. The outline of the embodiments of Figures 1 to 4 is provided on the respective side surfaces 2 only with one or both profile teeth 14 and a receiving space 5.

In Figures 23a) to 23i, the geometric shape of the profile teeth 4,4 'and 14,14' is essentially the same, but their lengths L and L 'are different, so that the hexagonal paving stones 1 must be laid in a predetermined position (not shown).

24 and 25, the hexagonal paving stone 1 is formed with different sides B 'and B'. By way of example, further possible contour variants are illustrated. However, they do not affect the formation of the profile teeth 4, 4 'and 14, 14' and their joint position when they are laid, but only alter the optical impression of the pavement.

Figures 26a-26c and 27a-ee show, in principle, the various designs of the chamfers 10, 10 'and the slope 11 on the side surface 2 and the profile teeth 4, 4' and 14, 14 ', respectively. 2-4). The embodiment of the slope is denoted by S, the R sign indicating the formation of a beam.

Figure 28 shows a basic outline of a modified paving stone, also a hexagonal paving stone 101. The paving stone 101 has support profiles on its side surfaces 102 having the same edge length B. The paving stone can also be formed with different lengths of edges and / or different number of corners, so that different pavement structures can be formed with different polygonal outlines.

The sidewalls 102, 102 'of the paving stone 101 alternate circumferentially between a groove portion 103 and a gutter portion 104 of FIGS. 3A. Thus, the support profile operating in the laying position (Figures 29, 31) is configured for a multi-hexagonal paving stone 101.

In the paving stone 101 thus formed, the support profile is provided with recesses 105,106 in the groove portion 103 and the gutter portion 104. These allow, with little effort, to improve joint stability in the paving position of paving stones 101 (Fig. 29).

Figures 28 and 30 show a top view of the paving stones 101 and 101 ', respectively, showing that the recesses 105, 106 and 105', 106 'extend vertically (i.e. perpendicular to the plane of the drawing) over the respective side surface 102, 102'. . In a preferred embodiment, and as a support profile, to reduce manufacturing cost, each side surface 102, 102 'has only one groove portion 103 and one single flap portion 104, respectively. However, it is also possible to have multiple support profiles with 105,106 and 105 ', 106' backs.

In order to provide a substantially complete shape in the stable laying position, the groove portions 103 and the eaves portions 104 have a substantially complementary cross-sectional shape at the recesses 105, 106 and allow simple vertical engagement when laying paving stones 101. 28 and 30 show a preferred embodiment in which the flap portions 104 and the groove portions 103 have an acute-angled triangular shape at the recesses 105, 106. A rectangular or arcuate outline of the backs is also possible.

In another embodiment of the paving stone, in the paving stone 10Γ of FIG. 30, the circumferential circumference of the recesses 105 ', 106' is provided with complementary support beams 107, 108, so that both the production and the laying of the paving stone 101 'are simplified.

In another embodiment, the recesses may be formed on the sidewall 102, 102 'only over a period of overlapping length (not shown) such that the paving stones collide in the deposition position rotated by 180 ° at the time of laying. It is also possible, at least at intervals, to form a back incision in a horizontal circle on a given side surface4

EN 220 681 Β1 in inert support profile, not shown, so that after the paving stones are horizontally bonded, stability in the joint laying position is improved and sealing of the road surface can also be improved.

Fig. 32 is an enlarged detail of two paving stones 201, 20 lévő in the deposition position. When viewed in conjunction with the top view of Fig. 34, a polygonal outline of paving stones 201, 201 '(here, a regular hexagon) can be recognized. The two adjacent paving stones 201, 201 'rest on one another with their lateral surface 203 facing each other and perpendicular to the surface 202 of the stones 202 to form a pavement gap 204 to form a common pavement.

In this embodiment, the paving stone 201, 201 'is provided with grooves 205, 205' on the side surfaces 203 (Fig. 32, Fig. 33), so that in a plurality of paving stones 201, 201 '(Fig. 34) on each side surface 203, a receiving chamber 206, 206 'may be formed which is substantially enclosed.

In the preferred embodiment (Fig. 37), an elastic sealant 207 is introduced into the receiving chamber 206, 206 ', which at least partially fills the corresponding receiving chamber 206, 206'. In a preferred embodiment, the sealing material 207 is a cord 208 which is additionally covered with a self-adhesive sealant 209, such as bituminous adhesive or the like, to improve the seal.

32-37. In the receiving chambers 206 and 206 'shown in FIGS. FIGS. 20 to 206, the grooves 205 and 205' are configured to form a receiving chamber 206, 206 'which is substantially horizontal in the deposition position of the respective paving stones 201, 201'. The grooves may also be formed in an outline of a meander shape (not shown) and the respective groove sides 211 and / or groove base 212 (Fig. 33) may be profiled such that the receiving chambers have different cross-sectional shapes such as a properly formed sealing material 207. to enable paving stones 201,201 'to be laid quickly without additional aids.

Instead of the single groove 205, 205 'shown in FIGS. In the embodiments of Figures 1 to 4, the respective sidewalls 203 of the paving stones 201, 201 'may have a plurality of parallel grooves (not shown). This allows, with little effort, the sealing material 207 to be positioned at different heights of the side surfaces 203, or multiple receiving chambers can be used as sealing areas at the same time.

In a preferred embodiment, the grooves 205, 205 'are positioned at the same height on each side surface 203 of the adjacent paving stones 201, 201' so that a receiving chamber 206, 206 'is formed sufficiently large on both sides.

In the embodiment of the paving stones 201,201 'shown in Fig. 33, the side surfaces 203' are provided with extensions 214, 214 'extending from the grooves 205, 205' with respect to the upper side surface area 203 ', so that the lower extensions 214, 214' overlapping 202 and forming a superimposed joint portion 204 'near the surface 202 of the paving stones 201,201', the width B of which allows a small amount of retrofitting of the sealing material 207.

The pavement stones 201, 201 'of Fig. 34 have vertical support profiles 215 on the lateral surfaces 203 of each of the paving stones 203, which intersect the groove 205,205' at least at intervals. The support profile 215 is provided with a toothed groove portion 216 and a gutter portion 217 in a complementary and stable supporting engagement with a plurality of paving stones 201, 201 '. By such a design of the support profile 215 and the perforated groove 205, 205 'it is possible to produce, at low cost, a support profile providing a particularly high load-bearing stability of the stones and a laying gap 204 or joint portion 204' protected against infiltrating harmful substances.

Figure 35 and the right of Figure 36 show a possible configuration of the receiving chambers 206 '. Accordingly, only one side, such as the gutter portion 217 of the support profile 215, has a 205 "groove. Such a single-sided arrangement of the receiving chamber 206 'is particularly applicable to the edge portion of a paving not shown. The end stones with the corresponding flat side surfaces and the sandy stones described above are then laid together.

38-41. FIGS. 6A and 6B are cross-sectional views of further embodiments of paving stones 1 and 201 according to the invention that improve the tight sealing of the traffic surface. All of these are provided with a sealing joint body 300 integrated into the stone body, which, for example, is simultaneously poured into it when the concrete stone is produced.

In the embodiment of Fig. 38, the sealing joint body 300 is formed on the rim side as a frame portion 301 surrounding the sidewall 2 of the paving stone 1, the anchoring portions 302 of which are molded to form the paving stone 1. Thus, the frame portion 301 is connected in a form-locking, counter-hook manner to the stone body. In the illustrated deposition position of the two paving stones 1, the respective frame portions 301 are directly adjacent to each other and are connected at the upper part of the laying trough 312 by, for example, glued or welded joint seams 312 'so that the gap 13 is sealed.

39-42. Figures 4 to 5 show further embodiments of the sealing connection body 300. The sealing body 300 is formed, as shown in FIGS. 39 and 40, with a rib profile 314 extending with its free end into the trough 312 or into the receiving chamber 206 by being secured to the stone body by counter-hook portions 302 '. The strip profile bodies 314 are always connected in the deposition position shown in the vicinity of the connecting seams 312 'such that the expanded chamber portions are also sealed. In the embodiment shown in FIG. 41, the frame portion 301 is similarly combined with the receiving chamber 206 of FIG. 40, as in the embodiment of FIG.

In a preferred embodiment, both the frame portion 301 and the strip profile body 314 are comprised of thermoplastic, so that the connection seam 312 'can be formed by a simple heating element in the laying position.

With the hexagonal outline described above, a paving stone is formed which, in particular in a flat laying position, is substantially uniform with each other at 120 °.

EN 220 681 Bl creates a high degree of stability of the leaning stones with its sidewalls. At the same time, the individual stones have increased resistance to breakage and reliable tight sealing at the placement gap.
