Avalanche barrier

¹ ^ The innovation concerns an avalanche barrier.

There are avalanche barriers known from avalanche arresting devices consist, which are formed from a wire rope network, these. = wire rope network from a large-meshed net consists of strong ropes, which should also catch large boulders and ice, and one above it laid fine-meshed, thin-wire net, which prevents the flow of loose snow avalanches or small pieces of debris should prevent. These networks are often like that

difficult that they can hardly be without a motor vehicle by human strength alone Can be brought to their place of installation and thus the actual purpose, which is why one snow fences trains from nets, namely the lightness and easy portability, thwart.

Change snow fences, e.g. walls of drifting snow or snow bridges consisting of beam gratings that are fixed
are anchored in the ground. Beam gratings only provide the avalanche with one that is perpendicular to the direction of movement

Area, whereby even with small deviations the Baikendo

rust to this vertical the avalanche can slide on the grating and thus the effect of the fence is canceled will. Beam gratings of this type must, in order to develop their effect, therefore over a large width of an endangered area

Slopes are led,

DE- ^ PS 21 36 469 is a snow avalanche weekly fence known, which consists of tubular posts and flexible catching devices of light weight * This fence must also have a extend the great breadth of a slope to take effect. This creates a passage for animals and also for Made difficult or impossible for people. The fence is relatively expensive to manufacture.

In contrast, the innovation has the task of an avalanche barrier element to create that is easy to manufacture, transport and assemble and with which a Lawi "L5 protection system is to be implemented for animals and Memschen does not represent a significant obstacle to passage.

This task is renewed according to an avalanche barrier element with two perpendicular or against the 2Q vertical inclined plates released from a rigid Consist of material and which are arranged at an angle to each other.

Compared to the large-area contiguous avalanche fences of the prior art, the avalanche barrier element according to the invention offers the advantage that avalanches made of snow or rubble are broken up, slowed down and finally stopped. Particularly effective is an arrangement of the renewal contemporary Lawinenverbauelemente in combination "with each other _n. The avalanche barriers do not block any passages on the slope, but leave openings free so that animals and people can pass the secured area relatively unhindered. The individual Lawinenverbauelemente can be arranged so that they have little barren does not interfere with the _"K landscape and nature.

Behind the individual elements can easily be afforested with trees, since the elements have a good Provide protection. The parts of the avalanche barrier elements are preferably hot-dip galvanized and can then be used for the purpose of Landscape protection and rust protection can be painted as desired. Individual elements are better blown free by the wind as large cohesive structures, like large fences.

_n The plates of the avalanche barrier element advantageously have openings to allow small amounts of snow or rubble to slip through. This reduces the surface loading of the panels. the

υ. both panels can be put together from a single piece

Metal or plastic that is bent to the 15th

to achieve angled arrangement of the two plates. In this way, an avalanche barrier element according to the invention particularly easy to manufacture.

If other material, e.g. wood, is used

"20th

or if the transport or other circumstances require it, the two panels can also be manufactured separately and at the installation site using known X <- connection types such as screws, rivets, welding or gluing

be connected to each other. You can do the one on top of the other

butting edges of the panels also perform so that the panels can be hooked together and thus none further connecting elements such as screws, rivets or the like are required.

30th

The avalanche barrier element is advantageously in the ground anchored. This anchoring is often sufficient in places where experience has shown that avalanches are only just beginning to emerge are understood. An avalanche barrier then prevents the initial movement of a mass of snow or debris, which avalanche formation is prevented.

A self-built one is often built on the slope side dormant wedge of earth and rubble, which already when walking away from Earth mass causes a division and so the element in front protects against great forces.

Depending on the situation, a new avalanche protection element Anchoring devices on / to be able to catch avalanches that have already occurred »As an anchoring device are suitable e.g. B. chains, ropes or rods that - if arranged at occupied heights, the elements hold and at the same time cause a division in the horizontal plane. Because such avalanches

can apply a surface pressure of up to 40 t / m ² , a simple fastening in the ground is often no longer sufficient for a safe catching of the avalanche. Another advantage of the guy racks is; that they cut up and split avalanches in motion and thus further reduce the possible pressure on the avalanche barrier.
20th

Another advantageous option for stabilizing and securely erecting an avalanche barrier is offered a support that supports the avalanche barrier element on the side facing away from the avalanche in relation to the ground.

An avalanche barrier element according to the invention provided with bracing devices can also be used in the most difficult of buildings be set up where previous barriers cannot be installed.

Staggered installation of several avalanche barrier elements in the building results in stools or humps, which makes them special on smooth slopes, a reduction in the creep and sliding pressure of snow and debris is achieved.

The innovation according to the invention can be in any widths, for. B. from 1.0 - 4.0 m width and heights, z. B. manufactured up to 3 m so that a good adaptation to the respective local conditions is possible.

Further advantages, features and possible uses of the present innovation result from the following Description of an embodiment in connection with the drawing. Show in it:

licher way directed uphill. The avalanche barrier

1 consists of two plates 2, 3 made of metal, plastic, wood or some other rigid material.

The plates 2, 3 have openings 4 through which a small amount of snow or debris falls on the avalanche facing away from the side of the plates 2, 3, whereby the pressure on the avalanche barrier element 1 is reduced. The two plates 2, 3 are vertical or they are inclined with respect to the vertical. You're at an angle 6 arranged to each other. This angle 6 opens in the direction from which an avalanche is to be expected. These Arrangement can be achieved in that a plate

2 is screwed together with a plate 3 at an edge 10. Other types of connection, such as welding,

riveting or gluing are also conceivable. Another option is to have a single plate, its total area equal to the sum of the areas of the two panels 2, 3 to bend at the edge 10, so the avalanche barrier element 1 to get. Such an avalanche barrier element 1 is particularly easy to manufacture and the connection of the two flats 2, 3 has a high degree of strength.

On the mountain side of the avalanche barrier element, that is the side on which the angle 6 of the two panels 2, 3 is included, are one or more Abspapnvorrichtungen 5 attached. In the illustrated embodiment, four tensioning devices 5 are shown. The guying devices 5 are arranged in the vicinity of the vertical edges of the avalanche barrier element 1. The guying devices 5 can be designed as chains or ropes. Other devices, such as tension bars, are also possible.

The avalanche barrier element 1 has connecting devices 7 / which with counterparts 8 of a further avalanche ¹ -

construction element 1 can be brought into engagement. This makes it possible to use a system of avalanche barriers, which are connected to one another by means of the connecting devices 7 and the counterparts 8 and braced are to create. This allows the avalanche barriers 1 support and secure each other.

The connecting devices 7 and the bracing devices 5 can have turnbuckles in the usual way.

Fig. 2 shows an avalanche barrier line t 1 from the other side, i.e. facing away from the expected avalanche Page. A support device 9 supports the avalanche barrier element 1 from the side facing away from the avalanche. In In the embodiment shown, only a single support device 9 is shown. However, they are arbitrary many support devices 9 possible. These support devices 9 are attached to the avalanche barrier element, for example by screwing, welding or riveting. It may be useful, the support devices 9 with the Only to wedge avalanche barrier element 1.

Whether a bracing device 5 or a supporting device 9 for fastening and stabilizing the avalanche barrier element is used on the slope depends on the conditions in which the avalanche barrier is used. In principle are both safety devices possible, can also be used together.

-δι surface, but are broken at the outer edges of the avalanche barrier element 1. This alleviates the initial pressure surge on the avalanche barrier element 1. The impacting snow or debris are held in the following by the angled plates 2, 3 of the avalanche barrier element 1, so that an alignment of the avalanche barrier element 1 that is not exactly perpendicular to the direction of movement of the avalanche does not involve the risk of the avalanche slide . The avalanche barrier elements shown in FIG. 3 have
several superimposed plates 2 and 3, the
may be provided with holes 4 if necessary.

If further snow or debris masses follow, a wedge of snow is created above the avalanche barrier element 1 or rubble on which the avalanche splits and divides itself. In the interaction of several avalanche barrier elements 1 can be achieved '.- / ground that the avalanche gradually is braked.

The avalanches are also generally cut up by the connecting devices 7, with which the individual avalanche barrier elements can be connected to one another
and braked.
