Definitions

  • the invention relates to a silo, in particular for grain storage, consisting of at least one cell, each cell being formed from wall elements and having peripheral supports which are cast with a potting material.
  • Silos of the type mentioned are known.
  • the individual cells are defined by wall elements, as described below with reference to FIGS. 1 and 2.
  • the wall elements can have, for example, a trapezoidal cross section, on the end faces of which end plates are welded.
  • the end plates have such a shape that an octagonal support is created by inserting four such end plates, for example.
  • the joints of the end plates are each offset from the adjacent end plate.
  • the cavity of a U St Tze thus formed is filled with concrete example.
  • the invention has for its object to provide a silo of the type mentioned, in which no flat iron must be welded in the area of the silo locks to absorb tensile and compressive forces.
  • the wall elements have anchoring elements on their end faces, wherein the end faces can be formed by end plates welded to the wall elements in accordance with the previously known silos.
  • the anchoring elements protrude from the end faces and are aligned approximately with the center of the respective support.
  • the anchoring elements can be formed by head bolts, T-beams or similarly shaped elements which, after the supports have been filled with a material such as concrete, are present in a bond with the concrete.
  • the anchoring elements are welded to the end faces of the wall elements; the anchoring elements are provided U about the height of the wall elements in distance from one another several times, and can have, if necessary, different lengths.
  • T-shaped anchoring elements e.g. T-beams, flat bars or the like can be used as anchoring elements if the silo in question is mainly exposed to compressive forces.
  • anchoring elements are provided offset with respect to the center line of the end plates.
  • the anchoring elements are provided on the side of the center line either on the middle section or on the side sections of the end plates or between the middle section and the side sections of the end plates.
  • the anchoring elements of an end plate are divided into two or at least two groups, the one group of anchoring elements being offset vertically with respect to the other group.
  • the attachment of the anchoring elements to the side sections of the end plates, ie directly next to the, is particularly advantageous the parts of the support locks carrying side sections, since in this embodiment the forces generated in the support lock area are transmitted to the anchoring elements in the shortest possible way and are thus introduced into the support.
  • FIG. 1 shows a schematic sectional view of a support 1 of known silos.
  • the support is formed by wall elements 2, 3, 4 and 5, on the end faces of which end plates 6, 7, 8, 9 are welded.
  • the end plates 6 to 9 preferably have the shape shown in FIG. 1, which is explained with reference to the end plate 6.
  • From each base 6a are two sections 6b that run obliquely to the base 6a and 6c are provided which are inclined at an obtuse angle with respect to the base 6 ⁇ .
  • the end plate is bent inwards and forms a hook-shaped bent end section at 6d, while section 6b is bent inwards at its end and then bent back to a hook-shaped section 6e. From Fig. 1 it can thus be seen that the hook-shaped end section 6e of an end plate 6 forms a silo lock together with the end 7d of the end plate 7, the end 7d engaging in the hook-shaped section 6e.
  • FIG. 2a shows a view of a cell along a section 2a-2a in FIG. 2b, two supports 1 and 1 'being indicated.
  • each cell 1 not only consists of four wall elements 2, 3, 4 and 5 with the associated, for example welded-on end plates 6, 7, 8, 9, but that several wall elements are provided one above the other, for example wall elements 10 , 11, 12, etc., which form the supports 1 and 1 'through their end plates.
  • a silo or the cells of the silo and thus the Silostutzen result from the fitting together of four wall elements according to FIG. 1 and by the U lying arrangement berrent- several wall elements according to Figure 2a, said wall elements 10,11,12 for example, the Wall 14 shown in Fig. 2b.
  • a silo can consist of any number of cells, as indicated by Fig. 2b, which illustrates only a part of a silo with square cells.
  • Each wall element 2 to 5 or 10 to 12 has an essentially trapezoidal profile and can contain at least one stiffening rib which is welded into the respective wall element.
  • the stiffening ribs are indicated in Fig. 2a with 15, 16 and 17.
  • the high tensile forces (corresponding to Z ⁇ in Fig.4) out 1 resulting from filling material, flat iron 20, 21, 22, 23 have previously been welded at a distance from one another according to FIG.
  • the flat iron 20 to 23 prevent loosening of the lock socket; for example, the flat iron 22 prevents the end 7d of the end plate 7 from being pulled out of the hook-shaped section 6e of the flat iron 6.
  • the flat iron 20 has the effect that the end plates 6 and 7 are firmly connected to one another in the region of their sections 6b and 6d via the flat iron 20.
  • FIG. 2 c shows a perspective view of a wall element, which is designated by 2. End plates, one of which is designated by 6, are welded onto both sides of the wall element.
  • the wall element has an essentially preferably trapezoidal profile and can be provided with at least one stiffening rib 15 on each side.
  • each support 1 is formed by wall elements 2, 3, 4 and 5, which are provided next to one another; As explained above, a plurality of wall elements are arranged one above the other in each vertical plane.
  • the flat irons 20 to 23 used hitherto are dispensed with.
  • anchoring elements 30, 31, 32 and 33 are used, for example in the form of head bolts, each of which is attached to the associated end plates 6 to 9 are welded.
  • the anchoring elements 30 to 33 After filling the support cavity designated by 34, the anchoring elements 30 to 33 are firmly seated in the concrete of the support cavity 34, not shown, and thus absorb tensile and compressive forces, so that a bursting of the support locks is effectively avoided.
  • the tensile and compressive forces that occur are explained with reference to FIG. 4.
  • the anchoring elements 30 to 33 in the form of head bolts are preferably butt welded to the associated end plates 6 to 9.
  • FIG. 4 shows a sectional view corresponding to FIG. 3 of a silo neck 1, the cavity 34 of which is filled with concrete.
  • the structural design of this support corresponds essentially to FIG. 3, 30 to 33 head bolts being provided as anchoring elements.
  • Fig. 4 illustrates the balance of forces due to forces caused by the filling material that is present in the surrounding cells.
  • wall friction loads P W occur which act along the wall elements 2 to 5.
  • the direction of the wall friction P w is indicated in Fig. 4 with respect to the wall element 2 and thus acts in a direction parallel to the axis of the support on the respective side surfaces of the wall elements 2 to 5.
  • FIG. 4 it can also be seen that the anchoring elements 30 to 33 embedded in concrete initiate the forces transmitted from the wall elements to the support 1 U into the support itself and provide resistance to the tensile forces Z.
  • Z d denotes the resulting tensile forces of the tensile force components Z, while D indicates compressive forces which are introduced into the concrete of the supports and result from the horizontal silo loads P H.
  • a round anchor 35 is provided in the center of each support 1.
  • the round anchor 35 like the anchoring elements, is embedded in the concrete.
  • a base plate for example made of metal, is provided in a known manner at the foot of each support 1, with which the round anchor 35 is firmly connected.
  • FIG. 5 shows a perspective view of a silo support 1 corresponding to FIG. 4 to illustrate the arrangement of the individual anchoring elements. 5, the anchoring elements are indicated by the reference numbers 36 to 49. 5 also shows the manner in which the individual wall elements are pushed into one another via their end plates and thus form the support wall through the end plates.
  • FIG. 6 shows an embodiment modified from FIG. 3, in which 30 to 33 T-beams 50, 51, 52 and 53 are provided as anchoring elements instead of head bolts. Similar to the head bolts 30 to 33, the T-beams 50 to 53 are welded to the surface of the end plates 6 to 9 facing the support cavity. These T-beams can preferably be welded on in such a way that the base or base section of the T-beam lies in the horizontal plane comes, which corresponds to the position of the head bolts 30 to 33 in Fig. 3, which are also substantially in the horizontal plane.
  • T-beams 50 to 53 U-profiles or anchoring elements of other shapes can optionally be used.
  • T-beams or flat irons are sufficient as anchoring elements, since the pressure forces occurring in such silos are adequately absorbed parallel to the nozzle axis.
  • the use of headed bolts as anchoring elements is preferred, since the headed bolts, due to their flange-shaped end which is distant from the respective end plate, result in a firm fit in the later filled concrete mass. This means that the head bolts 30 to 33 sit firmly in the hardened concrete due to their flange-shaped head end and can therefore absorb the tensile forces acting orthogonally to the column axis Z (FIG. 4).
  • T-beams or flat bars are only used if, in particular, compressive forces are to be absorbed parallel to the nozzle axis.
  • FIG. 7 shows a perspective view of a silage neck with the associated wall elements corresponding to the exemplary embodiment according to FIG. 6 and shows the position and arrangement of the T-beams 50 to 53.
  • the T-beams are designated 55 to 62 in FIG. 7.
  • the round anchors 54 are at least provided as an assembly aid.
  • trapezoidal stiffening ribs 63 are provided which, depending on the length of the wall elements, are welded several times and at a distance from one another into the trapezoidal recesses of the wall elements. The bending resistance transverse to the profiling of the wall elements is thus increased by the welded-in stiffening ribs 63 securing the cross-sectional shape of the wall elements, and so on an expansion or enlargement of the folding angle of the wall elements is prevented.
  • FIG. 8 shows a further modified embodiment of a support for the silo according to the invention.
  • the wall elements are not shown, but only the end plates 6 to 9 welded to the wall plates and T-beams 50 to 53 as anchoring elements.
  • a round anchor 54 is provided, which is surrounded by reinforcing bars 65 to 70, which are arranged lying in a circle around the round anchor 54.
  • the reinforcement bars 65 to 70 are surrounded by a reinforcement cage 71 and wired to the same.
  • the cavity defined by the end plates 6 to 9 is provided with concrete filling, i.e. the concrete filling also fills the interior defined by the reinforcement cage 71 with the round anchor 54 and the reinforcement steels.

It is from the top of the U St Tze corresponding to Figures 10a and 10b connect the round armature 54 with the end plates 6 to 9 of the wall elements uppermost U via a connection strut. 72; if necessary, a further connecting strut 73 lying crosswise to the connecting strut 72 can also be provided, which is indicated by dashed lines in FIG. 10b. 10a shows a side sectional view along the line 10 ⁇ -10 ⁇ '.
  • reinforcement elements can be provided on the top of each silo support, which have dimensions such that they can be welded to the round anchor 54 so that the strut 72 and / or 73 can be omitted.
  • each silo can consist of any number of cells, as explained with reference to Figure 2b.
  • four silo sockets are provided per cell, which preferably have the shape of an octagon and are provided with reinforcing elements which extend into the column cavity.
  • the socket cavity of the associated silo socket is each poured with concrete, preferably concrete of grade B 25.
  • the assembly continues, i.e. further wall elements are placed, after which the cavity of the further column cavity is poured out after a further height of, for example, 2.42 m.
  • the mentioned mounting height of 2.42 m results from the stacked wall elements and can therefore be of any other size.
  • the total height of the silos or silo supports can be almost any size.
  • the wall elements preferably consist of sheets with a thickness of 2 to 3 mm, which are folded by cold profiling into sheets with parallel, trapezoidal cross sections in the direction of support. The folding results in a prismatic folding mechanism when transferring the loads of the individual panels of the wall elements.
  • the bending resistance across the profile of the trapezoidal wall elements is increased by welded-in stiffening ribs.
  • the use of a reinforcement cage 71 in the silo nozzle is particularly preferred when the individual silo cells have larger dimensions and thus higher pressure loads occur; the use of a reinforcement cage obviously increases the steel cross-section of the individual supports.
  • this can also be made of high-quality steel, for example St 52.
  • Silos which according to the invention are equipped with anchoring elements within the connecting pieces, can be installed in a significantly shorter amount of time compared to the conventional use of flat irons which are welded onto the support locks, since the wall elements with the end plates are preferably already before assembly or . the assembly of the silo cells are provided with the anchoring elements.
  • anchoring elements of any shape can be used.
