Definitions

  • the invention relates to an assembly support for inserting the lower spherical cap of a metallic ball container into a concrete bed, between which and the spherical cap a removable support ring for the sole cap and removable supports for the ring zones of the spherical cap connected to the sole cap or to the ring zones already connected to the sole cap attached ring zone sections are provided.
  • Spherical pressure vessels such as those used in reactor construction, are usually stored in a concrete bed, through which the loads that occur are transferred.
  • the lower spherical cap of the ball container is first built up in zones on a mounting frame on the concrete bed, after which water is let into the concrete bed, so that the floating spherical cap after removal of the mounting frame by letting the water out on spacers provided in the concrete bed can be lowered.
  • the remaining space between the spherical cap and the concrete bed is then poured with concrete in order to ensure that the spherical cap lies firmly on the concrete bed.
  • the assembly frame generally consists of a support ring for the individual ring zones resulting from the construction of the calotte from individual sheets, the sole cap first being placed on a support ring, while the sheets of the subsequent ring zones are attached to the successively assembled and through the assembly steps truss-like stiffeners are supported to form closed rings.
  • the disadvantage of these known assembly scaffolds is first of all that the comparatively large amount of material required due to the framework-like stiffeners, which naturally has a significant influence on the workload for the scaffold erection.
  • the introduction and removal of equipment or the removal of the inner support rings before the floating process is made considerably more difficult by the supports connected to form rings.
  • the invention is therefore based on the object to avoid these deficiencies and to improve an assembly support of the type described in such a way that not only the workload for scaffolding erection and dismantling is considerably reduced due to comparatively simple, little material use of supports, but also that Occurrence of additional constraining forces can be avoided.
  • the invention solves the problem in that the supports consist of individual, distributed over the circumference, radially aligned with respect to the center of the ball container pendulum supports and that at least three additional, evenly distributed over the circumference are provided for the uppermost ring zone of the calotte are supported only in the direction of the respective vertical plane through the center of the spherical container on the uppermost ring zone and on the concrete bed.
  • the provision of the individual pendulum supports also offers the advantage of a low use of material and good accessibility, because there is no need for the reinforcing rings.
  • the additional supports evenly distributed over the circumference, in the area of the uppermost ring zone of the spherical cap ensure that the torque loads that occur are removed when the supporting ring for the sole cap of the spherical cap is removed, because these supports are pivotally supported only in the direction of the respective vertical plane through the center of the ball container .
  • the spherical cap resting only on the pendulum supports could turn around a vertical axis through the center of the ball if these additional supports were not provided. Since the torques that occur about such a vertical axis are comparatively low, three or four of these additional supports, which can only be pivoted in the direction of the respective vertical plane through the center of the ball container, are generally sufficient to dissipate these loads.
  • Torques around a vertical axis are absorbed by the center of the spherical container with simple constructional means can be, the supports pivotable exclusively in the direction of the associated vertical plane through the center of the ball container each consist of two support arms which are arranged at a mutual distance in the direction of their pivot axes and are connected to one another in a torsionally rigid manner. Due to their mutual distance in the direction of their swivel axes, the torsionally rigid support arms form an effective support of the spherical cap against a rotational movement about the vertical axis through the center of the ball container, without preventing thermal expansion or the like, because these supports are related to a horizontal tangent the spherical cap can be swiveled.
  • the possible swivel axis is also specified by the distance.
  • a corresponding support against the calotte on the one hand and the concrete bed on the other hand is essential for the function of these additional supports.
  • the two support arms have pivotable support plates at their ends for support on the concrete bed or on the spherical cap of the ball container, good force introduction can be ensured without impairing the pivotability.
  • the support plates must be connected to the calotte in a manner that prevents them from sliding. This requirement can be met with simple means in that the support plates are held so that they cannot move between dome-fixed stops.
  • the lower cap 2 of a spherical container to be inserted into a concrete bed 1 is composed of a sole cap 3 and supporting rings 4, 5 and 6 attached to it.
  • This cap 2 rests on an assembly support which has a support ring 7 for the sole cap 3 and a plurality of pendulum supports distributed over the circumference for the ring zones 4, 5 and 6 attached to the sole cap 3.
  • at least three additional supports 9 are provided in the area of the uppermost ring zone 6 of the spherical cap 2, which are distributed evenly over the circumference of this ring 6 and can be pivoted on the concrete bed 2 only in the direction of a vertical plane through the center of the ball container. and are supported on the spherical cap 2.
  • these additional supports 9 consist of two support arms 10, which are arranged at a distance perpendicular to the vertical plane through the center of the sphere and are connected to one another by diagonal struts 11 in a torsionally rigid manner.
  • These two support arms 10 carry pivotable support plates 12 and 13 at their ends, by means of which the supports 9 are supported on the concrete bed 1 and on the calotte 2.
  • the support plates 12 and 13 are each provided with pairs of tabs 14, between which the support arms 10 or the like by means of bolts. are held, which protrude through openings 15 in the tabs 14 with appropriate play. Since the support arms 10 have convex end faces 16 (FIG. 3) and are supported via these end faces 16 on the support plates 12 and 13, the pivotability of the supports 9 is ensured in the extent of the play of the screw bolts in one direction, without the screw bolts with the Load supporting forces.
  • the additional supports 9 can fulfill their task, namely to intercept occurring torques about the vertical axis of the spherical cap 2, a displaceable connection between the supporting plates 13 and the spherical cap 2 must be ensured. 2 stops 17 for the support plates 13 are attached to the ring zone 6 of the spherical cap, the required connection between the supports 9 and the spherical cap 2 can be easily established.
  • the support ring 7 for the sole cap 3 of the calotte 2 is first introduced into the prepared concrete bed 1.
  • This support ring 7 can be adjusted in height with the aid of a hydraulic lifting device 18, which not only permits precise adjustment of the sole cap 3, but also rapid removal of the support ring 7.
  • the sole cap 3 resting on the support ring 7 must be positioned before the sections are attached following ring zone 4 are connected to the support ring 7 so that torques can be absorbed around the center of the ball container via the support ring 7. All resulting forces, whose lines of action go through the center of the ball, as is the case, for example, with the weight load, can be dissipated by the radially aligned pendulum supports.
  • the non-displaceable connection is achieved in the exemplary embodiment by ropes 19 which are tensioned between the lower sole cap 3 and the support ring 7 or the lifting device 18.
  • the ring zone 4 is welded in sections and supported by radial pendulum supports 8, which can be designed very differently, since it is only important to avoid torque transmission.
  • the adjoining ring zone 5 is then built up on this ring zone 4, with again pendulum supports 8 serving to support the mounting of the ring zone.
  • the torque load caused by one-sided attachment of the ring zone sections can be easily removed via the support ring 7 on the concrete bed 1.
  • the uppermost annular zone 6 must additionally be secured with torque-absorbing supports 9 in order to prevent the spherical cap 2 from rotating about its vertical axis when the supporting ring 7 is removed.
  • the pendulum supports 8 can only remove radial forces such as occur due to their own weight or due to wind loads, which has the advantage that no additional constraining forces can occur.
  • the pendulum supports 8 are first in the area of the ring zone 4, provided that these pendulum supports have not already been removed after the ring zone 5 has been attached, and the support ring 7 has to be removed, which can be carried out simply because between the pendulum supports 8 of the upper ring zones 5 and 6 for which there is sufficient space.
  • water can be pumped into the intermediate space 21, which carries the calotte 2 for the removal of the remaining supports 8 and 9. After these supports have been removed, the water pumped into the intermediate space 21 can be drained off via the line 22, the spherical cap 2 sinking into the concrete bed 1.
  • the position of the calotte 2 is determined during the lowering process by the guide blocks 20, which take over the function of the supports 9 with regard to the absorption of a torque load.
  • the spherical cap 2 is lowered until it comes to rest on spacers 23, which determine a pouring gap for a concrete layer, in order to ensure that the spherical cap 2 is properly seated.
