Definitions
- the invention relates to a method and system for producing spatial Supporting structures for the bracing of loose material according to the generic term of claims 1, 6 and 7.
- Spatial supporting structures made of wire mesh mats serve different purposes Purposes. They are used, among other things, as stiffeners for slope fixings and dam constructions known for different uses.
- a The field of application is the bracing of noise barriers Loose material, e.g. B. rolling and / or granular earth or stone masses, for. B. on Roadsides to be heaped up.
- the supporting structure consists in the Rule of at least two parallel rows, one after the other Wire mesh mats that are connected at their ends. If parallel rows of such a scaffold the long sides of the dam form, they are often connected to each other for stiffening purposes.
- tie rods are drawn in, which are replaced by wire mesh mats can be on the wire mesh mats forming the longitudinal rows are attached and usually parallel to those of these wire mesh mats crossing mats are arranged.
- Wire mesh mats which essentially consist of intersecting longitudinal and Cross wires exist, which are spot welded together.
- the Longitudinal bars are used to join together wire mesh mats. she are for this purpose with protruding, pre-bent, hairpin-like Provide ends, which is a cross bar of the following wire mesh mat reach around.
- This allows several wire mesh mats to be placed in flat packages transport and deliver. On the spot, the packages become accordion-like out pulled each other until one aligned arrangement of the wire mesh mats arises.
- the support structures of this type require cross-bracing from tie rods, which in cross bars the wire mesh will be hooked in, the parallel Form the longitudinal walls of the supporting structure.
- a known wire mesh mat for the pit expansion of a new purpose fed This wire drafting mat is so far limited to their use in line expansion and specially designed for it. It says namely the pledging of the default in the foreground.
- the task has the exposed mountain range between successive To cover track expansion frames and so people and material against stone fall from the To protect the mountains, the pre-pledge is done by cantilever wire warp mats, which first the Support from a second one that was set later Removal frame is missing.
- this mat with its connections another advantageous area of application opened, namely that of the beginning spatial structures and thus results in one one or more directions of the structure rigid connection aligned with each other Wire mesh mats that match the pressure of those in the Structure inserted mass resists and also both the assembly of the structure and its Stability rationalized and guaranteed.
- a strictly rectangular arrangement of the rows of mats in the spatial supporting structure is for the Invention, however not a requirement.
- the features of the claim 2 can be both rectangular and below other angles of mutually arranged directions of the supporting structure with the wire mesh mats used deal with. This is a consequence of the described Formation of the connection of the longitudinal wires, which is only rigid in one direction and thereby creates the possibility with a angled wire mesh mat or wire mesh mat row the direction of the structure as a whole or in at least one of its directions to change.
- the structure has in the longitudinal direction vertical walls 4a and 4 of the dam from aligned wire mesh mats 2 and 3, the longitudinal walls being constructed identically and to are arranged parallel to each other.
- Distances are transverse wire mesh mats 4 arranged that follow a direction of the structure, which is perpendicular to the longitudinal direction crosses. For example, the intersections are at 6 to 8 in Fig. 4 entered.
- Cassettes 9 which after erection of the structure be filled with rolling masses.
- the Longitudinal rod ends of the mats 2, 3 are in the figures 1 to 3 drawn more precisely. It can be assumed that in these mats the longitudinal bars to the mat level are arranged in mirror symmetry, d. H. on the side 18 there are longitudinal rod ends with a connecting part to be described below, while on the opposite side 19 the other cooperating with this and also Connection part described below available is.
- This longitudinal rod 15 of the mat 2 has one end (Fig. 3), a hairpin 20. This follows an arc 21 with which she bent back on herself is and corresponds approximately to a semicircle; to the Arch 21 connects a straight length 22. At the opposite since 19 is the longitudinal bar end on the other hand, a loop 23, which is used for the longitudinal bar 14 is drawn. This loop also has an arch 24 and an adjoining end length of 25. You is however on one side, namely in Fig. 3 the drawing level opposite the mat level cranked outwards and in the perineum. This Bend 14a covers both of those following the arch Longitudinal bar sections 26 and 25. Die Length 25 is also after the opposite Angled side of the mat with its free end 27.
- the mats 2, 3 aligned with one another are like follows one after the other: First the mat 2 with those connected to the bows 21 of her hairpins 20, straight lengths through the loops inserted behind the crossbar 28 until the length 22 is fixed behind the cross bar 28. For this, the Mat 2 pushed up so that the length 22 in the loop 23 shows. The mat 2 is preferred until the inside of the arch 21 of the root 29 of the Loop attachment is present. This pushes it Length 22 in front of the arch 24 and the cross bar 28. Die connection made in this way is in the direction of cranking rigid, because the arch 21 is in the root 29 and the length 22 and the one belonging to it and parallel to it longitudinal bar on the cross bar 28th support.
- the crossbar 32 is first from the outside, i. H. of the back of the mat 3 pushed into the bend, until it is arranged approximately next to the cross bar 28 is ( Figures 2 and 3).
- the connection described can now be produced in the same way as the Connection explained above with reference to FIG. 3 has been. This is because the crossbar 32 has a smaller cross section than that Cross bar 28 and the two arches 25, 26 of the bend 14a of the sling 23 are selected such that except for the straight end length 22 of each hairpin 20 Cross bar 32 fits into the curve of the bend if the hairpin is inserted.
- This expanded The area of the loop is indicated by hatching in Fig. 1 indicated.
- the crossings are this way simultaneously with the connection of the following wire mesh mats in the longitudinal directions of the structure assembled.
- the direction of installation of the mats is taken 2, 3 from left to right, you will find them Hairpin ends of the first installed mats 3 am Beginning of the series.
- the direction 4 and 4a vertical rows can also be used with a Mat 35 (Fig. 7) can be started, as described above Mats 2, 3 corresponds.
- the hairpins are then not in the loops as shown in FIG. 3 arranged, but their length 22 are after their assembly between the welded Cross bar 28 and the loop bow 24 being the Hairpin bows 21 which include loop bows 24.
- This arrangement permits the right-angled arrangement the mats with a positive connection in the direction of Perineal pressure from the inside out.
- the arrangement described can also be the other Realize the dam to cross direction of the dam one parallel to the starting row Mount row of mats.
- this mat can be a Be mat 4, as shown in Fig. 3 on both Ends form-fitting at their crossing points with rows 4a and 4.
- a mat 4 is installed at the end of the dam, for example only loop ends stand for the form closure a mat of the longitudinal row is available. In in these cases, the mat 4 must be secured, which nevertheless the form closure in the Creates loops.
- a Mat that are used like mats 2, 3 is trained. However, this mat then stands over the last transverse row of the dam to the outside in front. To avoid this, it can be used as a backup used mat against the installation direction of the Mats in rows 4a and 4 can be assembled until the security mat of the last mat 2 in the Row 4a or 4 is on the outside.
- the straight lengths 22 of the hairpins 20 of the security mat against the installation direction of the mats 2, 3 then in the slings are pushed in until they cross the bars 28 and 32 in the slings and hairpin bows 21 of the bend 14a.
- the use of wire mesh mats 2, 3 in the embodiment 4 together with mats 35 7, the transverse direction of the rows 5 and 9th run has the advantage that one can Transverse stiffening of the dam only a mat 35 too need to assemble, which forms the gradation 36.
- the Longitudinal bars 37 to 42 have the length of the lower one Dam width B and correspond in number the longitudinal bars 10 to 15 of the mat 3.
- the longitudinal bars 43 to 46 are shortened, but arranged so that they are on a mat side 48th as shown at 30 and 31 in Fig. 8 and from 3 can be seen ending at a cross bar 49. It then there is a width b of level 36, the the degree of shortening of the longitudinal bars 43 to 46 depends on the longitudinal bars 37 to 42.
- the lower longitudinal bars 57 are the upper Longitudinal mat 53 and the upper longitudinal bar 58 of the lower embankment mat 54 each with a cross bar 59 to 60 of the mats 53 to 54 in broken Representation shown.
- the comb-like element 56 has a plurality of cross bars 61 in parallel Arrangement on. They are kept relatively short. Their ends are through on a longitudinal rod 62 Spot weld 63 attached and point just below their welds 63 bend, whose apex 64 has a short end 65 with the longitudinal bar 62 and a longer end 66 connects to each other.
- the comb-like element 67 shown in FIG. 11 largely corresponds to element 56. Its shorter Bars 68 are, however, in place of the unwinds provided with hairpin-shaped ends 69 which the Hairpins 20 in the exemplary embodiment in FIG. 3 correspond. With these elements 67 can the ends of the dam form-fitting in the way connect as is in connection with FIG. 3 has been described.
