Definitions
- the present invention relates to an enclosure with a vertical axis forming a reservoir or silo, of the type formed from a casing with a tubular appearance reinforced externally by belts arranged at intervals along the tubular body of the casing.
- Enclosures in particular silos for the storage of bulk materials, of the aforementioned type, are well known to those versed in this art. These enclosures generally have at their lower part a hopper allowing a gravity emptying of the enclosure.
- the first family relates to cylindrical enclosures with interior walls of circular section, the enclosures being hooped by angles.
- the second family of speakers with a vertical axis relates to the polyhedral enclosures made up of flat side walls connected to each other by corner uprights with concave inner section, the whole being fretted by belts made up of tubular profiles with constant quadrangular section to form a rectangular or square frame.
- These speakers an exemplary embodiment of which is provided in patent FR-B-2,701,983, have several drawbacks. Due to the planar configuration of the side walls, these do not participate in the recovery of horizontal forces. Consequently, the thickness of the walls, which is relatively large due to the nature of the products stored, is not used to contribute to the solidity of the assembly.
- Enclosures with a horizontal axis are also known, as illustrated in patent FR-A-2.10.839. These enclosures consist of an ovoid-shaped tank, hoops formed by metal dishes applying to the walls of the tank and a structure of general parallépl top ⁇ dique appearance consisting of upper and lower crosspieces connected together by spars. interrupting the sleepers. These crosspieces adapt like saddles to the curvature of the upper and lower parts of the tank. However, these crosspieces are not connected to each other at each end so that they do not constitute a belt of the enclosure. This results in the impossibility of strengthening the solidity of the entire periphery of the enclosure under the radial forces of the enclosure under load. Consequently, such crosspieces do not constitute the equivalent of a belt. Furthermore, it should be noted that these crosspieces are not produced in the form of a continuous section since they are interrupted by longitudinal members.
- An object of the present invention is to provide an enclosure with a vertical axis having a new architecture which makes it possible to reinforce the solidity of the enclosure under the radial compression forces of the enclosure under load.
- Another object of the present invention is to provide an enclosure whose architecture makes it possible to work the entire wall of the enclosure.
- Another object of the present invention is to provide an enclosure whose design makes it possible to eliminate any dead space between the belt and the interior envelope of the enclosure.
- the subject of the invention is an enclosure with a vertical axis forming a reservoir or silo, of the type formed by a envelope with a tubular appearance reinforced externally by belts arranged at intervals along the tubular body of the envelope, characterized in that each belt externally forms a polygonal frame, which internally has a curved profile, the cross section of the belt decreasing as that one moves away from an angle of the frame to form, inside the frame, a continuous curved template on which are joined in contiguous contact, directly or via a connecting piece, the walls of the tubular casing.
- the invention also relates to a method of manufacturing an enclosure of the aforementioned type.
- Figure 1 shows a perspective view of an enclosure according to the invention
- Figure 2 shows a perspective view of a profile participating in the production of the belt
- FIG. 3 represents a flat blank view from which the profile comes
- Figure 4 shows a top view of a belt in the assembled state of the sections constituting said belt.
- the vertical axis enclosure object of the invention, consists of an envelope 1 with a tubular appearance reinforced externally by belts 2 each forming a closed line around the tubular body of the enclosure and arranged at intervals along the tubular body of the envelope.
- These horizontal reinforcement belts 2, arranged at different heights along the external wall 1A of the enclosure, are joined to the latter to constitute a means for resuming horizontal forces.
- Each belt is externally inscribed in a polygonal 2A frame, preferably quadrangular, and in particular square or rectangular.
- This closed continuous frame, of rectangular or square external profile internally has a curved 2B profile. Indeed, the cross section of the belt
- this frame 2 decreases as one moves away from an angle of the frame in the direction of a perpendicular bisector of this frame to form, inside this frame, a continuous curved template on which will be secured in contiguous contact, directly or by means of a connecting piece (not shown), the walls 1A of the tubular casing 1.
- the interior section of this frame 2A is therefore a generally ovoid-shaped section, as shown in FIG. 4, which will correspond subsequently to the perimeter defined by the walls 1A of the tubular envelope 1.
- These walls 1A will thus have a curved profile allowing them to take up at least part of the horizontal forces and thus participate in the solidity of the enclosure.
- Each frame 2A forming a belt 2 is made up of sectioned sections 2C assembled by miter cutting.
- Each 2C profile generally made of metal, consists of a blank
- FIG. 3 An example of a flat blank 3, from which a profile 2C is produced, is shown in FIG. 3.
- This flat blank 3 has, after cutting, two concave longitudinal edges 3A and two trapezoidal lateral edges 3B.
- the small bases of each trapezium of the lateral edges 3B are interconnected by lines L1, L2 of parallel longitudinal folding originating at each angle of the small base of each trapezoid.
- the profile 2C assumes a shape conforming to that shown in FIG. 2.
- the connecting part between frame 2A and walls 1A of the casing 1 can be made up of a deformable metallic dish having a radius of curvature of shape substantially complementary to the interior profile of frame 2A. This flat is thus applied against the concave longitudinal edges of the profile and closes the latter.
- This plate is joined by welding on the one hand to the profile, in the assembled state or not of the latter, on the other hand to the wall 1A of the envelope 1.
- the walls 1A of the casing 1 are, in their conventional manner, made up of several sheet metal panels joined together by welding at their contiguous edge.
- the belts 2 are secured to the panels by fixing to the external face of the panels.
- the belts are placed at regular intervals, along a template, externally forming a polygonal frame internally having a curved profile, the cross section of each belt decreasing as one moves away from an angle of the frame in the direction of the perpendicular bisector of this frame to form inside the frame a continuous curved template.
- the enclosure entirely prefabricated, is subsequently equipped in its lower part with a hopper.
