Description

The invention relates to a laying plate according to the preamble of the claim 1, as used to support or cover the floor outdoors.

Thus, EP 0 576 939 B1 discloses a laying grid plate with a circumferential one Outer frame, on its side surfaces coupling means for connection two adjacent grid plates are provided. Here are as coupling devices on each outer side of the receiving frame T-shaped hook parts provided, while on the opposite side to the underside of the plate open passage is provided, the hook part in one of the behind engaged The inside of the wall snaps into place. These laying grid plates can be used for parking lots, paddocks or other usable areas and remain at least for a long time sunk in the ground and are not suitable For a quick to set, clean tread, which also easy to keep clean and even after a rain is quickly dry again, to be used.

From the brochure "ECORASTER" of the company purus Arzberg GmbH, 95659 Arzberg, is also a laying plate known with the same coupling system as described above, only that here additionally provided in the walls of expansion bends are the dimensional changes due to temperature variations absorb elastically. As these grid plates do not have a closed surface either they are also not as a clean cover z. B. for a fairground suitable.

The object of the invention is to provide a laying plate o. Genus and a laying plate arrangement which makes it possible to quickly get a clean floor cover to provide a safe appearance on this allows.

This object is achieved by a laying plate having the features of claim 1 solved. Advantageous embodiments are characterized in the subclaims.

Accordingly, the laying plate has a substantially closed at its top Cover plate, which with at least one linearly extending wave structure is provided in the longitudinal and transverse directions, wherein the wave structures in their longitudinal extent with their ends in each case to an expansion arc section the outer frame are brought close and to these on the entire arc length are spaced over a transverse slot. By the arrangement of itself crossing wave structures and their respective free outlet in the direction of the Expansion bends of the outer walls is a corresponding compliance of the cover plate ensured. In addition, the wave structures simultaneously form an effective Slip obstacle. Through the slits at the end of the waves can be cleaning or rainwater quickly drain from the plate surface into the ground. Through this However, openings can easily evaporate even moisture underneath, so that it can be said here that the underground is also after Can sufficiently "breathe" edition of the installation panels of the invention.

This "breathing" is promoted according to the invention by the fact that at the crossing points the longitudinal and transverse wave structures in each case a vertical breakthrough is present, preferably with a diameter approximately equal to the distance between two wave mountains.

It is advantageous if a wave structure consists of several waves, which extend over the entire length of the wall-expansion arc, wherein preferably three troughs are provided with intermediate two wave crests. As a result, the entire length of the expansion arch remains actively compliant, and this compliance is transmitted to its cover plate in the same way by the wave structure designed for approximately arc length. In addition, by the downwardly elastically freely yielding wave structures a pleasant, soft pedaling feeling is possible, the one on natural soil, for. B. a meadow is similar.
By the wave structures, the cover plate is divided into a plurality of uniform rectangular fields, preferably in square fields. However, in order to give the overall slab sufficient elasticity despite elastic wave structures, supporting wall rectangles are provided on the underside of the slab fields. In this case, at least one of the walls of the Stützrechtecke a straight portion of the outer frame at the outer frame directly adjacent fields. In the inner fields, which are surrounded around with wave structures and thus have a very elastic suspension, the support rectangles are designed larger and their walls brought close to the wave structures to give these fields the necessary slip resistance.

It can thus be seen that the supporting rectangles of the individual tread fields with each other not so in the inner fields or just over the arched ones Dehnwände of the outer frame communicate with each other, so that in each Direction a corresponding compliance of the entire plate is present.

To increase the impact resistance of the plate fields still is advantageous if the Plates on their underside additionally with diagonal, transverse or longitudinal ribs or abutments are provided. These ribs or supports prevent one Central bending of the fields within their support frame, so they too do not break higher center load.

It is advantageous if by the wave structures z. B. a plate in six, nine twelve or more fields is divided, wherein z. B. by a square shape with z. B. nine fields an optimal Verlegerasterung is obtained. then in an advantageous manner Way even additional plate dimensions of z. B. 330 x 330 x 30 mm or 330 x 330 x 50 mm for a nine-field plate and as plastic polyethylene - in more advantageous As a recycled plastic - selected, then according to the invention a very Stable and at the same time low-cost installation plate achieved, which also from the material Her some slip resistance provides. By additional arrangement on the fields of nubs - longitudinal and cross knobs - such. B. in sheet metal cover plates known arrangement or other corrugations, will be a maximum Tread and slip resistance generated by nubs, waves and material.

A laying plate assembly using the above-described laying plates is obtained according to the invention, if also strip-shaped coupling adapter are provided, whose length is at least the length of a laying plate or more Aneinandergekoppelter plates is, such. B. the length of two, three or more plates. These adapters have coupling devices on their longitudinal sides on, which correspond to those of the installation plates. However, allow it only the coupling elements of an adapter side a latching coupling with the Plates, while the other side is just a vertical pushing together, without snapping, allow. This is realized by the fact that the one adapter wall Coupling openings are assigned no undercuts or snap-in, so that the inserted coupling hooks of the plates, while clamping, but over their locking lugs can not lock. This allows the plate connection to this Coupling side also by simply moving in the Z direction, without special Effort and danger of destruction and without the use of tools, be made.

In this case, the adapter may have a downwardly open U-section and on its non-slip outer surface anti-slip nubs or corrugations own. Of course, for a good kick this should be slip-resistant Provided adapter surface be no higher than that of the fields and the wave structures of the bonded plates.

The installation plates according to the invention can in a particularly advantageous manner Large panels are pre-assembled, with several, for example, nine or twelve square panels are firmly snap-coupled to a large square. At two adjacent outsides of the large panel, on the two walls with the coupling holes, adapters become vertical via their coupling hooks pushed on and firmly locked. So now these can be provided with adapters Large plates only by vertical sliding, without engaging engagement, with another plate can be put together, and so can quickly and easily a large area will be covered cleanly and attractively. Should the cover be removed again, then do not have to plate by plate with the help of tools but it will be the individual plates or the large plates only posted at the intervening adapters of each other.

As can be seen from Fig. 1, a laying plate 1 according to the invention has a rectangular outer frame 2, the four walls 3 each have two arc sections 4, between which straight wall sections 5 are present. On the inner sides of the straight wall sections 5, each assigned to this, in the X and Y direction extending support walls 6 and 7 are provided, which form together with the associated wall sections 5 Stützrechtecke 8 and 9, whose function will be seen in the further. At the upper portion of the support rectangles 8, 9, diagonal ribs 10 or transverse / longitudinal ribs 11 are provided. In the interior, an inner Stützrechteck 12 is arranged, which is crossed by diagonal ribs 10, which in turn on its underside, except for the support surface vertically downwardly guided supports 13 have.
The laying plate 1 has on its upper side a cover plate 15, which are traversed by longitudinal and transverse wave structures 16 and 17. These wave structures each consist of several waves with wave arcs 18 and wave troughs 19, wherein in this embodiment, two wave crests 19, three wave troughs 18 are assigned. The wave crests and wave troughs 18 and 19 existing wave structures 16, 17 have a width which is approximately equal to the length of the arcuate portions 4 of the outer walls 3. In this case, the respective longitudinal end of a wave structure 16, 17 is brought close to the arc sections 4 and leave only a narrow gap slot 20 free for these. At the intersection between each two intersecting wave structures 16, 17 an opening 21 is provided in each case, which, as is clear from Fig. 3, is circular. Of course, it can also be rectangular.
The wave structures 16, 17 define in the cover plate 15 substantially planar rectangular fields 22, on the upper side of each longitudinal and transverse knobs 23 and 24 are arranged.
It can be seen, in particular in conjunction with FIG. 3, that in each case one rectangular box 22 is assigned a support rectangle 8, 9, 12 or projects on the lower sides thereof. This Stützrechtecke 8, 9, 12 serve to support the rectangular fields 22 on the ground, in addition, the ribs 10, 11 counteract bending or even breaking the rectangular fields under load. It is also interesting that the inner rectangular field, together with its Stützrechteck 12, by the surrounding wave structures 16, 17 "floating" is stored. It can thus at least slightly yield in all directions as a substantially independent box part by the wave or bellows attachment.

On the outside of the outer frame 2 are provided in a known manner as a coupling device, via the two adjacent plates firmly and practically undemountable zusammenkoppelbar, in each case two adjacent walls 3 and always on the straight wall sections 5, from the subsection horizontally protruding hook parts 25 consisting of a narrower longitudinal extension 26 and this transversely and upwardly towering transverse process 27. At the inwardly facing top of the transverse process 27 a hook nose 28 is present.
On the other two walls of the outer frame 5 are below open, also in the straight wall sections 5 downwardly open passages 29 are released, which in each case engage around a longitudinal extension 26 of a hook portion 25 when coupling two adjacent parts. The passages 29 are assigned to the inside of the wall sections 5 undercut stages 30, over which engage the hook noses 28 of the transverse extensions 27 of the hook parts 25 when coupling two installation plates 1.

From the section shown in Fig. 2 is in particular the shape of the wave structures 16 and 17 clearly visible, especially like these from troughs 19 and crests 18 are composed, each between the Stützrechtecken 8, 9 and 12 are free to run without any transverse to their longitudinal orientation Wall supports to communicate.

From Fig. 3 is a square installation plate 1, similar to that shown in Fig. 1, in a bottom view, which is coupled to an adapter 32. It can be seen that the adapter 32 has substantially the same coupling device parts as the installation plate 1, namely on the one hand passages 29, engage in the hook parts 25 of the installation plate 1 and on the other hand has hook parts 25, via which the adapter 32 is coupled to the installation plate 1 is. The provided here on the wall 34 here hook parts 25 of the adapter 32 are practically inseparable locked in the installation plate 1, while the bushings 29 of the outer wall 33 of the adapter in a subsequent, not shown here laying plate is pushed vertically, but it does not latch , as on the inside of the wall 33 no undercuts are provided for locking, as can be seen in more detail from Fig. 4 and 5. In addition, it can be seen that the adapter 32 has a downwardly open box shape, which is formed in cross-section substantially U-shaped in the wall, as is also apparent from Fig. 4 and 5 in more detail.
From Fig. 3 is also good to see that the installation plate 1 shown in the drawing is designed square and how at the bottom of the respective support frame 8, 9 are arranged, each straight wall sections 5 of the outer frame 2 assigned. It can be seen the intermediate wave structures 16, 17, each extending between two opposite arc sections 4, to each of which, however, a spacer slot 20 remains open. In addition, it can be seen how the inner rectangular box 12 supporting or supporting the inner rectangular field 22 is surrounded by the intersecting wave structures 16, 17 and openings 21 are provided as in the intersection points of the wave structures. Also here is the arrangement of the diagonal, transverse and longitudinal ribs 10, 11 can be seen and how they are integrated into the total formed by the Stützrechtecke 8, 9 and 12 geometric pattern with and for a secure support of the cover plate 15 and their individual rectangular fields 22 provide.

From Fig. 4 it can be seen how two installation plates 1, 1 'are coupled together via an adapter 32. The cross-sectionally U-shaped adapter 32 engages around the wall portion 5 of the outer frame 2 of the installation plate 1 'on the one hand by the hook portions 25 provided on its left wall 34 and is firmly suspended or latched with its hook nose 28 into the undercut 30 of the wall. This detent is practically no longer solvable, without fear that the hook parts 25 are destroyed.
The here right wall 33 of the adapter 32 is encompassed by the hook portions 25 of the wall portion 5 of the outer frame 2 of the right installation plate 1, wherein it can be seen that the wall 33 is made smooth on its inside, so has no undercut, in which the hook nose 28 of the hook member 25 could snap. Thus, the hook nose 28 is only under elastic pressure on the inside of the wall 33 fixed and can be moved vertically, whereby the connection between the installation plate 1 and the adapter 32 can be quickly and easily solved by vertical displacement of the two parts to each other. At the top of the adapter 32 also has anti-slip nubs 35. Here is also easy to see how the nubs 35 of the adapter 32, the longitudinal and transverse knobs 23 and 24 and the longitudinal and transverse wave structures 16 and 17 of the installation plates 1, the first 'allow safe accessibility of the laid panels.

The removable from Fig. 4 coupling two installation plates 1 and 1 'by a Adapter 32 can be seen particularly well from Fig. 5. Here is the one hand, the solid catch the hook parts 25 of the wall 34 of the adapter 32 in the undercuts 30 of the wall portion 5 of the outer frame 2 of the installation plate 1 'to recognize.

In addition, it can be seen how the hook parts 25 on the wall portion 5 of Outer frame of the installation plate 1 on their noses 28 only smooth, without any Snap on the flat wall 33 of the adapter 32 pending.

Finally, it can be seen from Fig. 6, as nine square installation plates 1 to a large plate 36 fixed, practically unsolvable are plugged together and like two Pages of the resulting large plate 36 a plurality of adapters 32 also snapped firmly are. About the externally apparent bushings 29 of the adapter 32 is this Large plate on the hook parts 25 of an adjacent large plate releasably clamped, so that quickly and easily cover a larger area with the installation panels covered and z. B. after taking place a concert or a festival these plates can be resumed quickly and easily. So it can be from "Quick floor" panels or "event" panels are spoken.
