Definitions

  • the invention relates to a support structure for substantially cylindrical and relatively thin-walled large containers such as silos, tanks, mixing containers, etc.
  • the container wall is to be made thick-walled when the forces acting on the container wall act unevenly.
  • These problems occur particularly when inside the container Apply forces along power transmission units, for example pipes, to singular points or special points on the container wall and such forces are then no longer effective tangentially, but in particular radially.
  • This risk of deformation also occurs when external forces attack the container wall unevenly. While one can eliminate such externally applied forces by additional supporting structures many times, which is at the respective crossing point of the forces to the vessel wall - are arranged, preparing the modeling Ver danger from the inside by acting forces many problems.
  • the invention / is based on the object of providing a support structure for such large containers which, despite its simple construction and essentially problem-free assembly, prevents the risk of deformation of the large container. ;
  • the invention / is that in the interior of the container at least one triangular support triangle is arranged in the container cross-section perpendicular to the container axis, the ends of which are supported on the inside against the substantially cylindrical container wall and are in particular firmly connected thereto.
  • This "fixed connection” means such a connection between the support triangle and the container wall that the forces transmitted from the support triangle to the container wall are essentially tangential forces within the container wall; the “fixed connection” can theoretically also be understood as a kind of "pivot point", “hinge line” or "pivot point”.
  • the support triangle therefore essentially has the task of converting the forces which occur unevenly within the container and in particular in the radial direction to deform, in particular bulge, of the container into such forces Forces which essentially only extend tangentially in the container wall, ie in the circumferential direction.
  • Such a support triangle is easy to produce, for example by connecting three support struts which form an isosceles triangle and are connected to one another by their ends. The circumscribing point of intersection of these triangular ends corresponds approximately to the circle which is formed by the central plane of the container wall which is circular in cross section, so that when the support triangle is inserted into the container or when the container is pulled onto the support triangle, the container is practically not deformed.
  • the triangular tips offset from one another in the container at an angle of approximately 120 ° prevent the container from denting at the relevant points, ie these triangles form an inward support there. If these triangular tips are not only loosely applied to the inner surface of the container wall, but are also firmly connected to the container wall, an even better transmission of force in the tangential direction of the container wall is achieved.
  • the support structure then represents the device on which the forces occurring unevenly in the interior of the container act; For example, pipes, if they transmit forces, are firmly connected to the support triangle, in particular by welding.
  • At least two support triangles are connected to one another in such a way that their ends are supported on the inside of the container wall - and are firmly connected to it - and that the support triangles are also firmly connected to one another in the vicinity of attack points of forces.
  • the support triangle to absorb those forces which would be transmitted from outside the container to the container wall if there were no support triangle according to the invention / in accordance with the invention.
  • the forces transmitted from the outside to the container wall are transmitted directly from the transfer point in the same direction through the container wall to the support triangle, which can be done, for example, by a force transmission element permanently installed between the relevant point of attack on the container wall and the support triangle.
  • a support triangle 2 is inserted into the container 1, the ends 3 of which are supported evenly over the circumference on the inside of the container wall 1 and are additionally welded on the inside of the container wall 1 a by means of welded connections 4.
  • the container wall 1 a is cylindrical and the cylinder axis corresponds to the container axis B. While the force transmission elements located inside the container, such as pipes, are not shown in this figure, it is clear that outer pipes 9 lead to the container 1 from the outside and are welded to the tank wall 1 a via welded connections.
  • the outer tubes 9, which exert radial forces P on the container wall 1 a are to a certain extent connected to the support triangle 2 for power transmission by means of extensions, ie in the same axial direction as the axes of the outer tubes 9, namely via welded connections 8 .
  • the outer tube 9 shown at the bottom right in FIG. 2 continues through the adjoining tube 7, so that a flow connection between the outer tube 9 through the container wall 1 a and the tube 7 and also via the support strut 2 c into the interior inside of the support triangle 2 is possible
  • the tube 7 shown in FIG. 2 on the left which forms the extension of the outer tube 9, bends downwards when the support strut 2a of the support triangle 2 is reached.
  • axial force P a is also shown schematically. Since such axial forces P a practically do not contribute to a deformation of the container wall 1 a, no special support measures are generally required in this regard.
  • FIG. 3 a combination of two supporting triangles 2, 2 'which are firmly connected to one another is inserted into the container 1.
  • These two support triangles 2, 2 are offset from one another by an angle ⁇ such that their ends 3, at which the support struts are connected to one another by welded joints 5, are separated from one another at a distance A U on the circumference of the container wall 1.
  • the schematically illustrated tube 7 transmits a first radial force P r1 in the direction of the arrow shown to the two supporting triangles 2, 2 ', which at the relevant point of attack of the tube 7 not only via welded connections 8 to the tube 7, but also via welded connections 6 are firmly connected.
  • welded connections 6 are present at the other force application points P r2 'P r3 between the support triangles 2, 2'.
  • welded connections are shown and described in the exemplary embodiments, other power transmission connections can also be used, for example rivets or screw connections, although welded connections have proven to be the most advantageous in most cases because of the rigidity.
  • the support triangle should be arranged in the container such that it transmits the forces essentially tangentially to the container wall;
  • the support triangle represents a force transmission element with an effect that changes the direction of the forces in the sense of reduced wall deformability.
