    Description: The invention relates to a load-bearing stop device, comprising a central weight base, in particular a multi-arm extension arm, with an attachment point for a safety rope to be fastened thereto.
    Such known in the art, load-bearing stop devices are intended to protect persons who work on roofs and other elevated areas, from falling and prevent the fall in the event of a fall or intercept. For roofs that are only entered for installation purposes or for the purpose of roof greening measures, permanent railing or other fixing points penetrating the roof surface and its insulation layers are dispensed with.
    The load-bearing stop device provides a deadweight fixed attachment point at which persons with personal protection equipment (PPE) secure against falling directly or are mounted on the so-called anchor devices, such as steel or fiber rope systems, in turn, persons with PSA secure against falling. In Germany and Europe, the requirements for such attachment points are specified, for example, in EN 795.
    The weight base of the particular used on flat roofs with up to 5 ° tilt stop device is usually multi-armed, formed with intersecting struts or beams, being provided in the crossing region of the boom of the vertically upwardly projecting attachment point for the safety rope and base weights either to the Ends of the cross-arms or between the cross-struts are arranged. For example, concrete slabs, gravel, gravel or the like are used as basis weights.
    The use of various weight materials is also dependent on whether the load-bearing stop device used temporarily, so each time built to carry out work and then degraded again, or permanently arranged on the roof remains. The roof skin always remains undamaged in both cases.
    Within the prescribed security specifications, some, i. limited shift of the load-bearing stop device in the event of a fall permissible. This sliding movement may even be desirable because it dampens the camber and thereby reduces the load on the individual parts of the stop device, on the safety rope and the falling person.
    The load occurring in the event of a load, so in a crash energy is absorbed by the load-bearing stop device, which prevents the crash only on the then onset sliding movement and the associated friction. Due to the vertically upwardly extending stop point for the safety rope, there is an increased risk of tipping the stop device in this sliding movement, which can ultimately lead to a crash of the person secured to it.
    The invention is therefore an object of the invention to improve a generic load-bearing stop device in terms of reliability and effectiveness in catching a fall, without increasing the demands on the roof surface or skin.
    This object is achieved in that the attachment point is connected via an energy dissipation element with the weight base. In the event of a fall of a person who is connected to the attachment point via a safety rope, the falling energy or fall force occurring is absorbed by the energy dissipation element. As a result, the energy dissipation element deforms and dampens the crash due to the energy absorption during deformation.
    According to a preferred embodiment of the invention, the energy dissipation element consists of several Z-shaped angled, at their upper horizontal webs about a the arrival point providing central plate star-shaped interconnected boom struts. In the event of a fall, the trapped over the anchorage point and the central plate falling energy or fall force in the star-shaped interconnected Z-shaped cantilever struts is derived. Along with this, the cantilever struts are progressively transferred from their vertical starting position into an inclined, possibly horizontal restraint position oriented in extension in the direction of fall, whereby the falling energy occurring during the fall is considerably reduced.
    At the same time with the flipping or deformation of the boom struts lowering the abutment point height is achieved and thus advantageously reduces the occurring in the event of a crash tipping moment associated with the Z-shaped boom struts weight base.
    Further, by the flipping of the boom struts and the associated energy reduction required for the retention frictional forces which occur in the controlled sliding movement of the load-bearing stop device in the event of a fall between the weight socket and the sensitive roof skin, reduced.
    A further embodiment of the invention provides that the lower horizontal webs of adjacent boom struts are connected to each other via foot struts. By means of the foot braces is achieved while maintaining the squareness of a quadratic dimensional stability of preferably four interconnected via the central plate, Z-shaped angled anchor struts.
    The invention advantageously provides that a first pair of mutually parallel Fußstreben introduced at the longitudinal ends, keyhole-shaped contour cutouts, while the longitudinal ends of the second pair of mutually parallel Fußstreben are formed with engaging in the keyhole-shaped contour cuts, complementary bearing eyes. The foot braces can thus be connected in a simple manner via a positive plug-in system. As a result, a certain concentric displaceability of the bearing eyes within the contour cutouts is made possible, so that the foot struts can be aligned in a horizontal plane exactly at right angles to each other. Furthermore, it is made possible by the positive connection that the Z-arms of the energy-absorbing element can be freely arranged at an angle to each other. Thus, spatial conditions of the footprint can be optimally utilized on site and at the same time defined load distributions can be achieved.
    The connection of the foot braces with the lower horizontal webs of the boom struts by means of threaded bolts, which inserted through aligned, provided in the bearing eyes and in the contour cutouts in the lower horizontal webs and the underlying weight socket holes and screwed into a thread of the holes of the weight socket become.
    The weight base may suitably consist of individual, transportable and befüllba-ren containers. The containers are arranged analogously to the star or cross-shaped connection of the boom struts on the roof or the roof skin. For receiving the lower horizontal webs of the boom struts, the containers are provided on their upper side with guide grooves.
    The containers can be filled, for example, with sand or water, which can be varied on the filled amount of the required coefficient of friction in the event of a fall desired sliding of the containers on the roof skin.
    A further embodiment of the invention provides that the central plate is circumferentially distributed with a plurality of holes for connection to the upper horizontal webs of the boom struts is formed. This supports that the Z-shaped angled cantilever struts can be fastened to one another with a horizontal angle different angle to each other, for example by means of a screw / nut combination on the central plate. Thus, irrespective of structural conditions on the roof surfaces, a flexible and exact positioning of the stop device with respect to the falling edge is guaranteed.
    Further details and features of the invention will become apparent from the claims and the following description of an embodiment of the invention shown in the figures: Figure 1 is a perspective view of a load-bearing stop device in the ready state, comprising as a weight base four star-shaped base weights which are connected to Z-shaped cantilever struts; Fig. 2 is an enlarged partial view of a Z-shaped boom struts at its upper
    Central webs connecting central plate; Fig. 3 is an enlarged partial view of the connection of a lower horizontal web of a Z-shaped boom strut footrests with a basis weight, shown explosively; FIG. 4 shows in detail the finished connection according to FIG. 3; FIG. and [0024] FIG. 5 Z-shaped cantilever struts arranged at different angular distances from one another on the central plate, shown schematically in plan view.
    Fig. 1 shows a load-bearing stop device 1, which is used in particular as fall protection for people on horizontal and up to 5 ° inclined roof surfaces.
    The stop device 1, as a weight base on a total of eight modular composite base or floor weights 2. The basis weights 2 are distributed over a total of four star-shaped rows, i. a row is formed by two base weights 2 lying one behind the other. On its upper side, the base weights 2 are formed with longitudinally extending guide grooves 3 for receiving an energy dissipation element 4.
    The energy dissipation element 4 consists of four Z-shaped angled cantilever struts n, each with an upper, short horizontal bar na and a lower, long horizontal bar nb (see Fig. 5). The respective lower, long horizontal webs nb are arranged in the guide grooves 3 of the base weights 2, while the upper, short horizontal webs are connected to one another in a star-shaped manner via a central plate 5.
    The connection of the formed with a mounting lug as an attachment point 6 for a not shown here safety rope central plate 5 and the upper horizontal webs na, as shown in Fig. 2, via a screw 7th
    As shown in Fig. 5 in more detail, the lower horizontal webs Nb four leg struts 8, 9, 10, 11 connected in such a way that while maintaining the squareness of a square shape stability of the stop device 1 is achieved.
    The foot braces 8 and 10 are provided at their ends with outgoing from their surfaces 12, keyhole-shaped contour cutouts 13, as shown in Fig. 3 and 4 only at one end of the foot brace 8. In contrast, the other two foot braces 9 and 11 are formed at their ends 14 complementary to the contour cutouts 13 bearing eyes 15.
    For a positive connection of the foot braces 8 to 11 is achieved, wherein a concentric displacement of the foot braces 8 to 11 in a horizontal plane is possible, so that the foot braces 8 to 11 can be aligned exactly to each other.
    The attachment of the foot braces 8 to 11 and the horizontal webs nb with each other and simultaneously with the basis weights 2 via a screw 16, wherein the play-free vertical fixation of the foot braces 8 to 11 large-size washers 17 are provided. In order to allow an accurate placement of the stop device with respect to a crash edge on roof surfaces, the cantilever struts can n with their upper horizontal webs na with a horizontal plane different angle to each other at the Central plate 5 are fixed, as shown in phantom in Fig. 5. The central plate 5 is provided circumferentially distributed with a plurality of spaced-apart holes 18.
    In the event of loading or falling, the traction energy introduced by the attachment eyelet 6 and the central plate 5 is taken up by the star-shaped interconnected Z-shaped cantilever struts n. These are progressively transferred from their illustrated, vertical starting position into an inclined, moving towards the base weights 2, possibly horizontal retention position.
    This is advantageously achieved that on the one hand reduce the frictional forces required for the retention process between the base weights 2 and the roof surface or skin and on the other hand by a simultaneous reduction in the height of the attachment eye 6 and the central plate 5 with respect to the roof surface or -haut the tilting moment of the load-bearing stop device 1 is reduced.
