Definitions
- the invention relates to a safety net according to the preamble of claim 1.
- EP 1 516 964 B1 describes a safety net, the net body of which consists of interlocking rings along its upper and lower longitudinal sides, each on an upper one extending between at least four supports and four floor elements or lower suspension cables is held displaceably.
- the two carrying ropes are slidably guided in their longitudinal direction at the upper and lower ends of the supports and in rope guide elements of the floor elements with which the support posts are anchored in the slope or on the rock and braced laterally.
- a running rope is provided which runs past the respective support, one end of which is attached to one side of the support and the other end to the other side of the support and is held displaceably on the running ropes in the support area.
- the invention is based on the object of creating a safety net in order to obtain an improved load distribution compared to the prior art as well as a more favorable flow of forces through the net body and a more uniform deformation structure in the event of a rockfall event.
- a preferred further embodiment of the invention is dealt with in claim 2.
- FIG. 1 a shows, in a schematic representation, the course of the rope of the safety net described in EP 1 516 964 only in the area of the upper longitudinal side of the net body in the unloaded state;
- FIG. 2a shows a schematic representation of the course of the rope of a safety net in accordance with ETA 14/0362 only in the area of the upper longitudinal side of the net body in the unloaded state
- FIG. 2b shows the course of the rope of a safety net according to FIG. 2a in the loaded state
- FIG. 3a shows a schematic representation of the course of the rope of the safety net according to the invention only in the area of the upper longitudinal side of the net body in the unloaded state
- FIG. 3b shows the course of the rope of the safety net according to the invention according to FIG. 3a in the loaded state.
- FIG. 4 shows schematically in an enlarged representation the course of the rope of the safety net according to the invention according to FIG. 3 in the unloaded state.
- the support cable a runs through all cable guide elements b. Additional running ropes c are clamped with their ends at points d on both sides of the rope guide element b on the supporting rope a.
- the net body is displaceable along the support cable a and the running cables c.
- Figure lb illustrates the safety net according to EP 1 516964 B1 in the loaded state.
- Figure 2a shows the course of the rope of another known safety net according to ETA 14/0362 in the unloaded state.
- the laterally tensioned support cable a shown in full lines runs through all cable guide elements bl to b4.
- the laterally tensioned support cable d shown in dashed lines runs through only the two outer cable guide elements bl and b4 and is guided past the two middle cable guide elements b2 and b3.
- Both suspension cables a and b are connected by means of connecting elements e.
- FIGS. 3 a, 3 b and 4 show a schematic representation of the course of the rope in the area of the upper and lower longitudinal sides of a net body, not shown, of the safety net according to the invention.
- the invention also includes safety nets with two or four inner supports.
- the safety net according to the invention contains, as shown, two outer supports la and ld and two inner supports lb and lc.
- Upper cable guide elements 2a, 2b, 2c and 2d are provided on the outer and inner supports la, lb, lc, ld.
- the upper primary suspension cable 3, shown in full lines and tensioned at the side end, runs through the two outer, upper cable guide elements 2a and 2d as well as the inner, upper cable guide element 2b.
- the upper secondary support cable 4 shown in dashed lines and tensioned at the side at the end, runs through the two outer cable guide elements 2a and 2d as well as the inner cable guide element 2c.
- a traction cable 7 and at least one central primary carrying cable 13 and at least one associated central secondary carrying cable 14 are provided.
- the middle primary and secondary suspension cables 13 and 14 are laterally braced at the ends.
- Middle rope guide elements 15 are attached to the tension elements 7.
- the middle primary suspension ropes 13 and the middle secondary suspension ropes 14 each alternately pass through adjacent middle rope guide elements 15 in the longitudinal direction of the network or are guided past them.
- the upper and lower primary and secondary suspension cables 3, 4 and 3 ‘, 4‘ are connected to one another by means of connecting elements 5 located between the outer and inner supports la, lb, lc, ld.
- suspension rope also includes several “suspension rope strands” containing individual suspension ropes.
