"Versugmatte for the expansion of the line in the mining industry"

Lie hiring concerns a Yersugaatte for the route expansion in mining, those of parallel and spaced apart Cross bars and longitudinal bars that old the Queretäben smoldered and at a mutual distance from each other are arranged.

The ends of the cross bars of such mats stand by the oldest the previously known Versugmatten over the respective sugeordered of the two outer longitudinal bars. You will be longitudinal bars generally cut from longer lengths and not processed further for reasons of cost. The sins are therefore soharfkantlg. They form sharp-edged ends of the cross bars a considerable risk of injury, especially underground where the mats are installed.

72056 * 6-3. ».Ti

The innovation is based on the task, this risk of injury to eliminate.

According to a first solution to this problem, the innovation in the case of the warping mat reproduced at the outset that the ends of the cross bars with the inside respectively associated with the cut off both outer longitudinal rods flush.

As a result, the formation can be sharper, protruding beyond the longitudinal bars Edges are avoided.

Another solution to the aforementioned problem is based on a warping mat, which also consists of parallel and spaced-apart cross bars and longitudinal bars which are welded to the cross bars and are arranged at a mutual distance from one another. In this known warping mat, the ends of the cross bars with hairpin-shaped bends as edge protection for the hat _; 3 provided. The hairpin-shaped bends on this hat are in the plane of the mat.

The solution to the problem on which the rise in prices is based is there in this mat training in that the level of

of the crossbar ends at right angles to the mat plane and the hairpin arches the relevant Enclose the ends of the cross bars associated with the two outer longitudinal bars.

This not only provides edge protection but also improves the behavior of the mats under the load of the rock pressure, In the case of extreme rock pressures, such distortion

Batten often so highly stressed that the strengths of the Locking of the cross bars with the longitudinal bars overstrained and the outer longitudinal bars detach from the mat. With the renovation & according to trained Versugmatte The hairpin curvatures of the crossbars increase the strength of the welds on the outer ones Longitudinal bars are attached. Even if there is firmness is exceeded, the mat retains the cohesion of the rods forming it at its outer edges.

The innovation is explained in more detail below with the aid of the drawings explained;

show it

Fig. 1 is a plan view of a warping mat according to the furnace,

2 shows a side view of a second embodiment of the delay mat according to the invention,

FIG. 3 shows a plan view of the object according to FIG. 2 in a representation corresponding to FIG. 1, and FIG

4 is a view of one of the ends of the mat according to FIGS. 2 and 3.

The Versugmatte shown in Fig. 1 is of several parallel longitudinal bars 1, 2 formed, which are arranged at a mutual distance. With the longitudinal bars are transverse bars 3, 4 welded, which are also spaced apart

in an orderly manner. The ends of the longitudinal bars 1, 2 can be hooked into » shaped ends.

You close the ends of the cross bars 3 and 4 with their assigned of the two outer longitudinal bars 1 or 2 flush. In the illustration of FIG. 1, this is the pail in the case of the one arranged above Longitudinal bar 2 and the longitudinal bar 1 arranged at the bottom,

This results in the desired edge protection.

Another solution to this problem is shown in FIGS reproduced. Here, the same reference numerals designate the parts corresponding to FIG. 1. Because the cross bars are designed identically it is sufficient to describe the shape of one of these cross bars.

Each end of such a transverse tab 3 or 4 has a hairpin-shaped bend. The hairpin-shaped bends arranged on the upper of the longitudinal bars in the illustration in FIG. 3 are denoted by 6, while the bends assigned to the lower longitudinal set from 1 are denoted by 7. Each of these bends has a hairpin bow 5 or 5 ', which surrounds the associated longitudinal rod 2 or 1 and the end of which is designated by ^-8 or 8'.

As can be seen, the hairpin surrounds are located at 6 resp. in the plane of the mat.

This ensures that the hairpin arches 5 and 6 are on the outer edges of the mat, where they form an edge protection.

72056 * 6-3.1.72

In addition, the two outer longitudinal bars 1 or 2 are additionally held by the hairpin bows 5 or 5 'assigned to them in each case.

In fig. 2 are hook-shaped ends 9 and 10 of the longitudinal rods 1, 2 reproduced.

Protection claims:

Claims (2)

Protection claims 1. Prosecutions for the expansion of the mining line by parallel and spaced from each other cross bars and consists of longitudinal bars that are connected to the cross bars are welded and arranged at a mutual distance from one another, characterized in, that the ends of the cross bars (3, 4) with them Cut off the respective assigned of the two outer longitudinal bars (1, 2). 2. Warp mat for the expansion of the mining line, made up of parallel and spaced-apart cross bars and laus longitudinal bars that are welded to the transverse bars and spaced from each other are arranged, the ends of the cross bars with hairpin-shaped Bends are provided as edge protection for the mat, characterized by that the level of the hairpin notes (5.5 ') of the Queretabenden (8.8?) Runs at right angles to the mat level and the hairpin arches to the ends in question of the cross bars associated with the two outer longitudinal bars (1, 2).
