  • silos of this type out of roof and floor units interconnected by a cylindrical side wall unit with the silo container'including in addition to the latter units a pair of connecting rings which serve to connect the side wall of the silo to the roof and floor units thereof with the components of the silo being clampedto these connecting rings.
  • silo constructions of the above type considerable difflculties are involved because of their relatively complex structure and the relatively large costs involved in transporting the relatively bulky components required for the silo. These components are assembled at the location where the silo is set up for use.
  • the silo includes a silo container made up of roof and floor means and a flexible foldable tubular side wall means extending between and connected with the roof and floor means.
  • Upper and lower connecting ring means serve to connect the side wall means respectively to the roof means and floor means.
  • a supporting framework is situated in the interior of the silo container and includes a central supporting column extending upwardly from the floor means and carrying the roof means.
  • This roof means is in the form of a supporting structure which is radially arranged around the supporting column and which carries the upper connecting ring means.
  • FIG. I is a schematic sectional elevation of one embodiment of a silo according to the invention, the plane of FIG. 1 containing the central axis of the silo;
  • FIG. 2 is a schematic vertical section elevation of another embodiment of a silo according to the invention with the plane of FIG. 2 also containing the central axis of the silo;
  • FIG. 3 is a schematic sectional plan view taken along line Ill-III of FIGS. 1 and 2 in the direction of the arrows.
  • the silo illustrated therein includes a steel supporting framework to which the outer silo container or cell is connected.
  • the floor means 3 thereof is first mounted in its position of use, and then the central supporting column 30 of the supporting framework is fixed to the floor means 3 extending upwardly therefrom.
  • This central supporting column 30 is braced with respect to a lower connecting ring means 5 by way of a plurality of elongated bracing means 32.
  • the plurality of elongated bracing means 32 may be in the form of suitable guide cables or elongated bars or bracing rods.
  • the supporting column 30 fixedly car-' ries adjacent its upper end aplurality of connecting lugs 33 which are fixed to and extend radially from the supporting column 30 while the connecting ring means 5 also fixedly carries a plurality of lugs 33, these lugs 33 being connected to the floor means 3 as well as to the lower connectingring means 5.
  • the plurality of elongated bracing means 32 are connected at their upper ends to the lugs 33 which are fixed to the upper region of the column 30 while at their lower ends the plurality .of bracing means 32 are respectively connected with the lugs 33each of which is connected in part to the ring means and in part to the floor means 3.
  • the column 33 is mounted on the floor means 3, followed by mounting of the roof means 1 on the top end of the column 30, as described above, the foldable tubular or cylindrical side wall 2 of the silo container is unfolded after being connected with the upper connecting ring means 4 which is carried by the roof means I at the outer periphery of the latter, so that during this unfolding of the tubular side wall 2 of the silo container it will extend .down to the lower connecting ring means 5, being clamped against the lower ring means 5 by way of a lower clamping ring 35.
  • the lower end of the cylindrical wall 2 is hemmed so as to surround a ring 19 which is situated directly beneath the lower horizontal flange of the clamping ring 35 while the vertical flange of the latter engages the exterior surface of the side wall 2 with the latter situated between the vertical flange of the clamping ring 35 and the connecting ring 5 in the form of a relatively short cylindrical wall, and this cylindrical or vertical flange of the clamping ring 35 is located directly over the ring 19.
  • Suitable bolts 16 are provided for pulling the clamping ring 35 downwardly, these bolts being connected to the horizontal circular flange of the clamping ring 35 as well as to the horizontal circular flange of the connecting ring 5, so
  • the roof means 1 of the silo is primarily made up of a supporting structure similar to that of a spoked sheel.
  • the supporting structure 40 of the roof means 1 is arranged radially around the column 30 and carries at its outer periphery the connecting ring means 4.
  • This supporting structure 40 of the silo roof means is covered by a woven fabric sheet material, for example, which is provided with a plastic coating, this sheet material being, for example, a Trevira woven fabric.
  • the side wall means 2 of the silo container is made up of a cylindrical, tubular woven sheet material which is seamless and which is also coated in a manner similar to the woven fabric sheet material of the silo roof means.
  • the fabric sheet material of the cylindrical side wall means 2 renders the latter flexible and foldable as well as lacking the rigidity to be self-sustaining.
  • the side wall means 2 is clamped by a suitable clamping structure to the upper connecting ring means 4.
  • the side wall means 2 is formed with a hem or tubular lower periphery in which is located the circular pipe 19 or simply a heavy hemp rope, so that the lower tubular periphery of the side wall means 2 in this way will have in its interior the ring 19 against which the clamping ring 35 is pulled downwardly as described above.
  • the floor means 3 of the silo container has a funnelshaped or tapered construction in the embodiment of FIG. 1 where it is formed by the steel tapered structure 13 which in turn is mounted onthe supporting framework 36 with the lower connecting ring means 5 being fixed to the floor means 3 and the framework 36 at the location where the steel structure 13 and framework 36' are fixed to each other.
  • the floor means formed by the tapered steel structure I3 is formed with a discharge outlet 8 in the form of a central opening at thebottom end of the tapered wall 13, and the discharge outlet 8 is opened and closed by way of a control means 11 in the form of a cylindrical valve member which is capable of being raised from the illustrated closed position to an open position and then again lowered to the illustrated closed position.
  • the column 30 carries in the interior of the funnel-shaped floor means 13 a tapered, frustoconical wall 10 the taper of which is opposite to that of the wall 13, the bottom edge of the wall 10 forming with the inner surface of the wall 13 the annular gap 37 through which the granular contents in the silo flows toward the outlet 8.
  • the control means 11 is in the form of a cylindrical member whose height when its lower edge engages the wall 13 as shown in FIG. 1 is great enough to extend higher than the natural inclination taken by the granularmaterial downwardly beyond the outer peripheral edge of the body 10 which forms the upper edge of the gap 37. Thus, any material flowing down through the gap 37 will engage the valve 11 when the latter is in its closed position shown in FIG. 1.
  • the valve 11 is connected by suitable cables 39, which are guided over suitable guide rollers or pulleys, to the piston rod of a hydraulic valve-actuating means 25 which serves to actuate the control means 11.
  • theillustrated central supporting column 30 is in the form of a pipe or tube having a hollow interior in which the actuating means 25 is accommodated and the cables 39 are of course guided through suitable openings in the wall of the tubular column 30 so as to be connected with the piston rod of the hydraulic means 25.
  • FIG. 2 the embodiment of the invention which is illustrated therein also has a silo container formed by a roof means 1, a sidewall means 2, and a'floor means 3, with the components being interconnected by the upper connecting ring means 4 and the lower connecting ring means 5.
  • the embodiment of FIG. 2 differs from that of FIG. 1 in that the floor means 3 is flat and located directly on the foundation means 31.
  • the column 30 of the inner supporting framework also extends upwardly from and is carried by the floor means 3, this column 30 being braced with respect to the outer ring means 5 which is mounted directly on the floor means 3 in the embodiment of FIG. 2 by way of the inclined bracing means 32 in the manner described above, and also it will be noted that the roof means 1 of FIG.
  • braced by way of the elongated bracing means 34 which extend between the outer peripheral region of the roof means 1 and the inner lugs 33 "which are fixed to and extend radially from the lower end of the column 30 directly next to the floor means 3.
  • FIG. 3 which shows in a plan view the structure either of FIG. 1 or of FIG. 2, the side wall means 2 is of a primarily circular cross section.
  • this cross-sectional configuration is not critical to the invention since any other type of cross section, such as an octagonal cross section, can equally well be used with the structure of the invention.
  • a granular material can be introduced in a well known manner through an opening at the roof means 1, and also with the embodiment of FIG. 2 the contents of the silo can be discharged in any suitable way.
  • a suitable discharge pipe may be embedded in the foundation when extending up to a suitable opening in the floor 3 and having a suitable closure gate or the like so that through the latter it is possible to control the discharge of the contents out of the silo of FIG. 2.
  • the top end of the side wall means 2 may be connected in any suitable way to the connecting ring means 4.
  • the tubular wall 2 may have elongated flexible tapes which extend longitudinally beyond the top edge of the cylindrical woven fabric sheet material 2, and
  • these tapes may be wrapped around and fixed with the ring which forms the connecting ring means 4.
  • This ring is fixed as by welding or any other type of fastening structure to the spokes of the roof structure 40, and the tapes at the top end of the wall 2 are wrapped around the ring 4 between these spokes.
  • the spokes which form the supporting structure 40 are arranged radially around the column 30 and are covered by a suitable sheet material such as a plasticcoated fabric sheet material.
