Plate-shaped element for a route

The invention relates to a plate-shaped element for a driveway, in particular a steel driveway, each element having a substantially rectangular driving plane Forms on its upper surface and on its two, to the longitudinal direction of the road transverse end areas fastening devices for a connection with an adjacent one Has element.

The starting point is the well-known flat steel road, which is an aid to the traffic at construction sites of roads, which must be closed due to renovations, next to the Redirect construction site. The plate-shaped elements of a flat steel road are 2.40 meters long, 12.25 meters wide and 30 meters high (see Lueger, Lexikon der Technik, Volume 11, 4th edition, keyword "Stahlflachstraße"), and thus only can be laid by machine. This alone makes assembly and disassembly difficult, but assembly and disassembly are also necessary made more difficult by the fact that the individual plate-shaped elements are connected to one another by additional connecting parts.

Compared to other methods of creating a route, however, the flat steel road has the advantage that the individual The subsurface bearing plate-shaped elements, hereinafter referred to as coarse subgrade, requires relatively little preparation and that a route can be created in a relatively short time, at least in a shorter time than for other methods is required to create a driveway, for example a concrete or asphalt road.

Furthermore, track plates for impassable terrain, such as deserts, are known which, like the elements of the flat steel road, are known Ground them on the existing floor without major preparations and form a stable, non-slip surface, can roll on the exn vehicle tires .; The advantage of this known, plate-shaped elements is that they are individually are manageable, so can be laid by hand. However, it is disadvantageous that they are individually and without connection to one another be relocated, whereby the. There is a risk that individual elements move transversely or in the longitudinal direction. Furthermore problems arise at the transition points on rough, bumpy subgrade between adjacent track plates, since the adjacent, transverse end regions are not connected to one another are, their position to each other is only due to the coincidental course of the rough subgrade, so that joints, tilting the elements and also damage to the tires of the vehicle rolling on the track plates are to be feared.

Based on the known, plate-shaped elements for a Fanrstrasse, the invention is based on the problem of the disadvantages to avoid this known, plate-shaped elements and to create plate-shaped elements that quickly and without additional auxiliary and connecting means can be laid, one Form a chain-like, coherent composite and are easy to manufacture.

This task is based on the known, plate-shaped Element solved in that the one transverse end region each plate-shaped element is connected to it in one piece, Undercut door handle open towards the end area has and that the other, opposite end region is designed as a ratchet hook, which is also one-piece Is part of the element and its pawl tip is transverse to the driving plane runs and points in the direction of the driving plane.

Due to the pawl parts which form the transverse end regions of the elements and are an integral part of the elements, a hinge-like connection is created between adjacent plate-shaped elements that can be easily clicked in and out, without additional connecting parts being necessary for this connection. The latch connection can be designed in this way be that at a certain angular position between two adjacent ones that is too large for practical driving Elements it is possible to put the elements together by inserting an already on the rough subgrade into the latch jaw Elements the latch hook is inserted at an angle from above. The inserted element can then simply be dropped the latch connection remains over a certain angular range, for example -25 °. A mounted A route made up of such plate-shaped elements thus forms a link assembly similar to a chain of a tracked vehicle. Due to the link structure, firstly, individual, plate-shaped elements cannot separate, secondly ensures that the transition between adjacent, plate-shaped elements is always smooth, orderly and flowing, Thirdly, unevenness in the rough subgrade is better compensated for than it is with individual, non-contiguous plate-shaped Elements is possible and fourthly is achieved that loads that are exerted on an individual element, partially be distributed to neighboring elements.

The plate-shaped elements according to the invention for a driveway are particularly suitable for mining. It is well known that large distances (paths) must be covered underground in pits today. For this purpose, one no longer wants to use rail-bound vehicles, but rather trackless vehicles, for example buses for the transport of the miners. According to the prior art, concrete is applied to the rough subgrade of the bottom of a tunnel or a stretch. Such ^

However, concrete roads have proven to be very susceptible to repair, as the mountain works and cracks appear in the concrete pavement.

According to the invention it is now proposed to the rough subgrade To lay the sole of a cleat, the plate-shaped elements according to the invention. The assembly of such a driveway is easier than creating a concrete roadway, a repair is only necessary to a lesser extent, since the invention Driveway can follow ground movements in an articulated manner and is overall much more adaptable than a rigid one Concrete driveway.

In addition, however, the use of the inventive Road intended for other, impassable terrain, for example construction roads to a construction site, which will be later must be removed again. Here, in contrast to others, the driveway according to the invention offers solid ground with the rough subgrade connected solutions, on the one hand, a reusability and, on the other hand, no overburden arises when they are removed.

It has been found to be particularly advantageous if the pawl tip is a few millimeters, in particular less than 10 millimeters, to be arranged below the driving plane of the element. This measure causes the between two adjacent, plate-shaped Elements necessary slot, which forms a transverse groove in the roadway, remains tolerably small, if the angle between two adjacent elements is in one extreme position, namely the angle apex outwards to Driving plane, lies.

The elements are preferably relatively short in the direction of travel, for example their length is 30 to 60 centimeters and their Width in the range of 1 meter. Thereby the individual

Elements, even if they are designed for a load from trucks or buses, are so light that they can be Workers can be comfortably carried and handled. Their weight is typically between 20 and 40 kilograms. In addition, such elements form a relatively short-term, closed chain that can adapt better to the unevenness of a rough subgrade than a relatively large one Elements, although a driving level sufficient for driving purposes is created.

It is particularly advantageous for the elements according to the invention, that individual elements are separated from a longer route formed by many interlocking elements without having to start at one end. It is removed by pulling one out from the side individual element from the link network.

So that the individual elements rest securely and non-slip on the rough subgrade, they have downwards on their underside protruding ribs that can be pressed into the rough subgrade. Preferably these ribs are through the outer surface formed of the pawl parts. This has the advantage that when a load is applied, the pawl parts are loaded directly without that a lever arm occurs. As a result, the jack connection is better maintained than with the Latch parts separate support ribs. Additionally be Stiffening ribs are provided to support the load-bearing capacity of each one Elements with substantial savings in material, so in particular steel, to increase.

A particular advantage of the elements according to the invention is their production from a rolled profile, because this means that the production costs are very low. The aim is to create it and using a rolled profile that is simply cut to length must be to the individual, for example 1 meter

long elements to manufacture. However, certain difficulties arise with the latch jaw. To circumvent these difficulties, it is suggested not to provide the lower arm of the latch jaw on the rolled section and subsequently to arrange the like or by welding. In particular, this lower arm of the ratchet mouth can only extend over a short length, at least not the entire width of the element.

Finally, it has been found to be advantageous to have a route made up of two adjacent sputen in the form of a link chain to create interlocking elements. In principle, it is also possible to have a relatively wide, for example 3 to 4 Meter-wide elements should be used, but these are no longer manageable. Also occur due to the roughness of the rough subgrade Problems caused by tipping and by spans that are too large to be bridged. Have for practical operation therefore elements that are only approx. 1 meter wide and thus only form one wheel track have proven themselves.

Further advantages and features of the invention emerge from the remaining claims and the description that follows of a preferred, but not to be understood as restrictive, exemplary embodiment that is referred to below is explained in more detail on the drawings. In this show:

The plate-shaped element of a driveway shown in FIG. 1 has on its upper side a substantially flat, easy-grip driving level 10 for practical driving, which is a rectangular area. It is in the embodiment shown Diamond-shaped, corrugated, but can also be provided with knobs, warts or a coating to make rubber tires to convey the best possible adhesion. The direction of travel is indicated by the double arrow 11. The element are, even if this is not immediately apparent from FIG. 1, significantly shorter in the direction of travel 11 than in Transverse direction to this, which is referred to as · width.

The element has on its, to the direction of travel 11 transverse End areas 12, 13 each pawl parts 14, 15 which are integral with the element. Here is the right end area 12 is designed as a ratchet hook 14, the hook tip 16 of which is approximately 8 millimeters below the driving plane 10. The latch hook 14 runs across the entire width of the element.

The opposite, left end area 13 is designed as a latch jaw 15 and is also an integral part of the element. This latch jaw 15 consists of an upper, slightly downwardly curved nose 17 and two individual, lower arms 18,19, which protrude at a certain distance from the side edge 20 and have a certain length.

Except for these arms 18, 19, the element shown in FIG. 1 is a rolled profile, the arms 18, 19 are subsequently attached to the lower base 21 welded to a rib 22. The profile shape of this rolled profile is the side surface 23 shown in dashed lines in FIG. 1. Overall after the rolling process and cutting the element to length, all that is necessary is to weld on the arms 18, 19, and then the elements ready for use.

The ratchet rack 15 is open in the direction of travel 11, it is, as the other two figures show more clearly, undercut, the mouth widens inwards starting from the mouth tip. The clear distance between the two is the mouth tip delimiting edges 24, 25 somewhat larger than the distance between the inner bay 26 and the lower end edge 27 of the pawl hook 14, as can be seen from FIG. As a result of this measure, the pawl hook can be in the position shown in FIG. 3 shown relative position of two elements are introduced into the ratchet mouth 15. This introduction is possible in the exemplary embodiment when the driving planes 10 of the two plates are at an angle of 135 ° to each other. Will after latching dropped the inserted element, so enlarged the angle between the two driving planes is 10, at a 180 ° angle the two driving levels 10 are in the same plane. Starting from this 180 ° position, one element can be opposite the other can be pivoted by - 25 ° (in the exemplary embodiment), whereby the articulated pawl connection is maintained, thus a tensile force can be transmitted from one element to the other element.

In Fig. 2, the two extreme positions of a left element are shown on the left, the opposite of a middle element pivoted by + 25 ° and once - 25 ° compared to the 180 ° position is. The plug-in position of the jack connection is shown on the right. Such an angular position, the one 45 "pivoting from the 180 ° position means comes with a practical route, so that an automatic release of adjacent elements is not to be feared. If one would like to make automatic notching even more difficult, can - without departing from the scope of the invention - the Einklinkwinkel can be chosen even larger. In general, the specified angles are only to be regarded as an embodiment.

The element is formed over most of its area by a plate of the same thickness, it is for example 8 millimeters thick. In addition, each element is stiffened in its central area by a reinforcing rib 28.

In practical use, in particular, only the arms 18, 19 and the base 21 rest on a rough subgrade, if this is reasonably level. If the rough subgrade is uneven, the support of the individual elements cannot be predicted. Because of of the link chain-like composite are, however, initiated when the bearing forces are not applied via the base 21 neighboring elements are also loaded and forces are transferred to them.

Just like the hook area, the latch jaw also runs in a transverse direction to travel direction 11 through. This makes it possible to get out a link chain-like composite of several elements any Pull out the element at right angles to the direction of travel. This may be necessary in order to carry out a repair or the like.

Instead of the illustrated, non-continuous arms 18, 19 can continuous arms can also be provided. In a rolling process, either the arms 18, 19 or the Lug 17 initially running away to the side and only later pushed into the position shown. Then later welding work unnecessary.

The element is preferably made of steel, in particular a steel with the following analysis:

0 = 0.13-0.16, Si = 0.30-0.40, Mn = 1.45-1.60, P = max. 0.030, S = 0.030, Al = 0.010-0.045, Cu = max. 0.08, Cr = max. 0.05, Ni = 0.06 max, V = 0.12-0.06, N = 0.014-0.018.

All data are in% by weight.

In addition to the production of the elements from rolled profiles, production from an extruded profile is also particularly cost-effective.
