Definitions
- the invention has for its object to provide an avalanche barrier element which has a support structure for the network which the assembly and the preparatory work for the installation in the
- an umbrella-like element which normally requires a single anchor point.
- Said umbrella-like element consists of a strut which is anchored directly or indirectly to the ground with the mountain-side end while the valley-side end carries a holder to which, in a common plane perpendicular to the strut, at least three beams which converge to the holder are fastened; practice has shown that an X-shaped arrangement of four carriers is particularly advantageous.
- the girders are articulated to the valley-side end of the strut, while the opposite ends are connected to the mountain-side end of the same strut and also to one another by means of wire cables in such a way that, in the case of four girders, a square (square, Rectangle, trapezoid) is formed by forming the diagonals; with a different number of carriers, the rope forms the corresponding circumference.
- the structure rests on the floor with three supports, namely with the end of the strut on the mountain side, which is also attached to the ground by means of anchoring, and with the ends of two of the beams arranged radially, which rest directly or by means of suitably dimensioned and possibly with a joint and / or with a compensation element for the floor irregularity provided support.
- the umbrella-like elements according to the invention can be assembled among themselves according to different geometric principles in order to form coherent barriers which run in different ways; to form barriers that are permeable to game, for example, without affecting the avalanche barriers or the snow through the
- the number of anchorages required to create an avalanche barrier corresponds to the number of structural units which form and are the avalanche barrier when using several umbrella-like elements according to the invention, in terms of the number of anchorages for conventional avalanche barriers with nets, reduced by a third. This means that the time spent on the site and the work involved in realizing and preparing the anchorages are kept to a minimum.
- the umbrella-like elements according to the invention are composed of profiles, pipes, ropes and known fasteners and connecting elements, whereby simple cutting, drilling and welding work is required, which is why the manufacture and assembly does not require specialized specialists and does not take long times, it can be metallic and non-metallic material are used.
- the technical features of the umbrella-like elements according to the invention enable the pre-assembly in the valley and the helicopter transport to the high ground, where, apart from the preparation of the anchorages, only the coupling of the elements themselves takes place.
- the outer ends of the beams arranged in a radial manner are connected to one another by means of a wire rope, in such a way that they also prevent spreading.
- the net can be attached directly to this circumferential wire rope and at the same time assembled with it.
- the invention does not rule out that the wire ropes which run from the outer ends of the girders to the
- Anchorage point of the strut converge all or in part at another location, between the two ends of the strut. Furthermore, the invention does not rule out that the plane in which the beams lie with the horizontal plane and / or with the vertical plane in which the strut lies forms an angle other than the right one in order to obtain force components which result from the load on the strut result in moving snow mass and act on the structure in such a way that it is prevented from being lifted and / or a lateral discharge or partial overflow of the snow mass is achieved, and an excessive load on the structure is thereby prevented.
- the anchoring of all or part of the wire cables converging from the outer support ends to the mountain-side strut end can be of an unyielding type or by the use of known elements such as springs, slide clamps, etc., so that a gradual yielding is exceeded when a certain load is exceeded takes place and so the cross section which is exposed to the effect of the snow masses is reduced.
- the same elements can also be used if the same wire ropes are attached or retained at any point on the longitudinal extension of the strut.
- the same elements can also be used if the same wire ropes are attached or retained at any point on the longitudinal extension of the strut.
- a valley-side bracing of individual avalanche barriers or, preferably, several avalanche barriers (e.g. three elements) to a common anchor point is not excluded. In this latter case, it is also possible to use part of the anchorages of the next barrier on the valley side for the bracing.
- Fig. 1 shows a perspective view of some umbrella-like avalanche barriers with a straight strut, which are anchored without alignment and mutual chaining.
- FIG. 2 shows a perspective view of the detail of the anchoring of an umbrella-like avalanche sheeting element according to the invention with the wire cables converging from the outer support ends to the anchoring end of the strut.
- Fig. 3 shows a perspective view of the valley end of the strut of the umbrella-like avalanche barrier element with the fastening element for the X-shaped carrier.
- Fig. 4 shows a perspective view of an umbrella-like according to the invention
- Avalanche barrier element with the two wire cables converging from the upper ends of the girders to a point on the longitudinal extension of the strut and with the representation of different, valley-side, additional bracing options or anchoring options.
- Fig. 5 shows a perspective view of an umbrella-like according to the invention
- Avalanche protection element with angled strut and reinforced in the knee is shown.
- Avalanche barriers with a net are drilled on the slope to carry out a series of anchoring in the rock or in loose soil according to the project and with the already known elements, consisting for example of wire rope, eyelet, thimble, etc.
- a connecting element lb is fastened to the thimble la by means of pins lc which receives the fastening end 3a of the strut 3 and the connecting wire cables 7 on a second pin ld, the outer ends 6, 6a of which are attached to the outer ends of the X-shaped means Mount part 5a attached to strut end 3b, support 4 connected.
- the four supports 4 are provided at the end which faces the holding part 5a with plates 4b which have bores 4a; a pin 5c inserted through the bores of these plates and through the bore 5d on each of the flanges of the holding part 5a with a cruciform cross section, welded onto the end 3b of the strut 3, connects the carrier to the end of the strut.
- the mechanical connection between the X-shaped arranged beams 4 and the connecting part 5a is articulated and ensures, due to the play between the assembled elements and between the pin 5c and the corresponding seats, easy play in several directions.
- the ends 6a of the supports 4 directed towards the floor and the upward ends 6 of the supports 4 are connected by means of a single wire rope 8 which is circumferentially connected and at each of the outer ends 6, 6a of the supports 4 by means of a clamp against spreading of the supports is secured.
- the ends 6a of the supports 4 directed against the floor can lie directly on the floor or rest on prepared supports or can be equipped with support elements, with or without a joint and / or elements which enable the compensation of unevenness in the floor.
- the dimensions of these support elements 2 depend on the permissible load on the floor.
- the valley-side part of the structure can additionally be attached to the floor by means of anchoring 12, which lies essentially along the straight line which runs through the support points of the supports 4 and by a binding, which e.g. on the wire rope 8 which connects the outer ends 6a of the carrier, on the ends 6a itself or on the support elements 2 attached to it, are secured.
- anchoring 13, 13a is also possible, which acts on the outer upper ends 6 of the carriers 4, or on the point 5 where the carriers converge; in this case anchoring 12a is required which is at a certain distance from the valley to the straight line which runs through the supports 2.
- the anchor point 12a can be used for several avalanche barriers which form the same barrier and it is also the use of the anchorages 1 of the
- the wire ropes 7 which run from the outer ends 6, 6a of the carrier 4 to the anchoring end of the strut 3 can run all or in part through a binding 3c, which is provided on the longitudinal extension of the strut 3, then run on
- Anchor end 3a of the strut to be attached alternatively, all or part of these wire ropes can be attached to the binding 3c, which allows the wire ropes 7 to slide or give way in the event of maximum stress.
- Said solution is of course also applicable to angled 3d or curved struts 3, which allow a change in the angulation of the plane in which the beams 4 lie with respect to the slope, and thus to the direction of action caused by the movement of the
- the bends 3d can be reinforced 3e and can optionally be provided with fastening elements or bindings for the wire cables 7.
- the angling can also be carried out from a joint, e.g. a hinge joint which can be locked in different angular positions.
- a joint e.g. a hinge joint which can be locked in different angular positions.
- the umbrella-like elements according to the invention can be distributed and anchored so that coherent
- Barriers possibly of aligned and / or interlinked elements, arise that interrupted barriers are formed with different courses or by assembling individual and independent elements according to different geometrical arrangements to form a structure.
- the brackets 11 held by the X-shaped arrangement 4 and by the connecting elements 8 can, together with all other parts of the sheeting element, already be mounted and connected in the valley to the wire cables 7, which converge towards the mountain-side end 3a of the strut 3 limit the work in the field to the anchoring by inserting the pin lc through the thimble la.
