Definitions

  • the invention relates to a reservoir carried out as a non-removable construction, especially swimming pool, with a bottom and side-walls and provided with wallparts of plastic material with vertical ribs.
  • a first difficulty is, that the side-wall parts of such a reservoir will be exposed to difficultly predictable pressure forces, especially if the reservoir is placed in the soil. This holds more when the reservoir is placed in the open air in which case variation of the surface-level of underground-water, settling of the ground and such like cause very strongly variable pressures on the wall.
  • the reservoir may be as well empty as filled, which for instance with a swimming pool, even if winter-conditions are not considered, regularly will be the case in view of cleaning purposes.
  • each wall-element is capable to resist its own pressure-load, also because with the design of the construction it is difiicult to consider the length of the side-walls.
  • the invention provides a solution, enabling this purpose and maintaining a light construction.
  • at least the wall-parts which form the side-walls and are made out of synthetic material, are anchored at their lower sides and provided with a stiffness decreasing form bottom to top, the relatively large stiffness at the lower side being obtaining by means of ribs having at their lower side a greater height than at the upper side, the parts of the ribs having the higher height being part of the anchorage.
  • the relatively higher rib parts at the lower side of the side-walls not only provide a greater bending-resistance to the side-wall parts at the location, where they are exposed to the largest bending momentum, but they provide at the same time the rigidness of the connection between the side-wall parts and the construction, to which they are anchored.
  • the side-wall parts are supported by separate manufactured foundation-elements which extend at the side opposed to the reservoir beyond the ribs of the side-wall parts. Since the foundation-elements extend outside the reservoir these extensions will be loaded by a considerable groundweight, by reason of which in a relatively simple way it is secured that the variable ground pressure can be resisted. Moreover it is possible to obtain the result, that only once concrete has to be poured, in the wall parts are connected to the foundation elements by means of concrete. On the contrary if a bottom of concrete is made, this has first to be poured and to harden out at least in a considerable degree, after which the side-wall parts can be adjusted and fixed by means of complementary poured concrete.
  • An embodiment of the invention for transferring the overturning forces exerted on the side-wall element to the foundation exists in tension struts between the extensions of the foundation elements and the ribs.
  • This construction has the advantage, that the foundation elements can be carried out relatively light-weighted, but the separate anchorage, which has to be corrosion-resistant to underground water in some instances may be an undesired element.
  • the side-wall parts have been inserted in a groove in the foundation elements which allows adjustment in horizontal and vertical direction as well as adaptation of the angle between the foundation element and the wall part.
  • the possibility of adjustment of the sidewall parts is especially important, when the foundation elements, at least locally, have an orientation differing from the horizontal position, e.g., at the end of a tilting bottom, as occurs in many cases with swimming pools.
  • the obtained groove can be filled with concrete and it is possible to apply in the longitudinal direction of it a reinforcing connecting the different foundation elements solidly with each other.
  • the foundation elements are provided with a standing wall, that in combination with a side-wall part forms a gutter, that is filled with concrete.
  • the foundation elements cannot shift in a horizontal direction under influence of the wateror ground-pressure.
  • the lower side of the foundation elements is provided with recesses.
  • the invention also includes a wall element adapted for the manufacturing of a reservoir according to the invention.
  • FIG. 1 shows a cross-section over the line II of FIG. 3 through a side-wall element with an anchorageconstruction
  • FIG. 2 shows a cross-section through the same element over the line II- -II of FIG. 3;
  • FIG. 3 shows a part of two adjacent side-wall parts
  • FIG. 4 shows a cross-section through a side-wall element with anchorage analogous to FIG. 2 of another embodiment of the invention
  • FIG. 5 shows a side elevation of the construction according to FIG. 4;
  • FIG. 6 shows a detail of the connection of the bottom plates to each other.
  • FIG. 7 shows a cross-section analogous to FIG. 4 through still another embodiment of the invention.
  • side-wall parts of the reservoir mean the parts that constitute the vertical of nearly vertical delimitation. Preferably these parts have been mounted along the complete circumference of the reservoir, but this is not essentially for applying the invention.
  • a reservoir-bottom has been indicated of preferably reinforced concrete.
  • ribs 6 have been connected to the shell-part.
  • These ribs consist e.g. of a core 7 of form-resistant foam-plastic on which a skin 8 of plastic has been applied, preferably glass-fiber reinforced polyester.
  • the shell-part 3 consists of this plastic and the skin of the ribs form together with the shell-part 3 a unitary construction.
  • a joint 9 of for instance concrete that has been made watertight by means of epoxy resin is applied at the frontside of the shell-part 3 and the sealing of the reservoir can be obtained by means of a strip 9a placed in an angle, on which epoxy resin is spread, its being established that such a layer of glass-fiber with epoxy resin adheres sealingly and permanently to as well the concrete as plastic of the polyester type.
  • a beam 10 of reinforced concrete is poured, the reinforcing elements 11 of which form the connection between the bottom 1 and the beam 10'.
  • the beam 10 may also be provided with longitudinal reinforcements.
  • the rib has at its upper side a relatively small height, which height, however, increases between the points A and B, to remain beyond these again constant and finally to increase again between the points C and D.
  • the height increasing part C-D is located within the concrete beam 10 and by means of this assures a further improvement of the fixation of the sidewall part 2.
  • Adjacent side-wall parts have been connected at their ends by means of angled flanges 12. These flanges have at their innerside V-grooves 12a, in which flexible sealing rods 12b, e.g. of artificial rubber have been applied.
  • flexible sealing rods 12b e.g. of artificial rubber
  • FIG. 4 With the embodiment of FIG. 4 the wall elements 2 have been inserted in a groove 13 of foundation element 14 which in the shown embodiment consists of reinforced concrete and at its lower side is provided with recesses 15 for a better adhesion in horizontal direction to the supporting soil.
  • the foundation elements 14 extend in the direction opposite to the reservoir, consequently in FIG. 4 towards the right, beyond the side-wall parts. On these extending parts soil will rest, by reason of which groundpressure on the side-wall parts working in FIG. 4 in the left direction can be resisted in a considerable degree, if not completely.
  • the groove 13 has at its lower side a curved form, which facilitates the adjustment in different directions of the sidewall parts, As, however, the connection between the side-wall part 2 and the foundation element 14 extend only over a relatively small height of side-wall part 2 the possibility exists, that, with load exerted by the ground pressure in the left direction of FIG. 4, very high tensions in the lower part of side-wall part 2 will be induced.
  • tension struts 16 For absorbing these tensions tension struts 16 have been applied, that at 17 are anchored in the foundation elements 14 and at 18 are connected to a rib of the wall part 2.
  • This connection is more especially visible in FIG. 5 and consists of a fork 19, both legs of which are placed to both sides of rib 6.
  • a hole is drilled in the rib, preferably through predrilled holes in fork 19 and in these holes a pin or bolt 20 is inserted.
  • the whole strut construction 16-20 consists of stainless steel.
  • the bottom is composed of thin plates 21 of plastic material. These are connected to each other by means of a back-plate 22, to which the lower ribs 23 of plates 21 are connected by means of stainless poprivets 24 (hollow rivet that can be inserted from above and fastened by means of a special suitable tool) whereas the whole construction is sealed by a sealing strip 25, as more clearly indicated in FIG. 6. It has been shown that such a construction remains well watertight, also if it is supported by a soil surface which is not completely flat or shows small saggings.
  • the foundation elements 26 consist of a bottom part 27 and-an upright part 28.
  • This upright part is provided at its upper side with a rim 29 extending towards wall part 2 whereas the reinforcing of foundation elerrient 26 locally protrudes from it (at 30).
  • the concrete beam 31 which in other respects mainly corresponds to the concrete beam 10 of FIG. 2, strongly with the foundation elements 27.
  • These foundation elements have advantage, that they can easily be piled in that an element turned over is placed upon an element in the shown orientation, in which case the protruding reinforcing 30 does not hinder the transport.
  • each side panel being made of resilient synthetic plastic material capable of yielding to soil pressures to a substantially greater degree than reinforced concrete;
  • each flange being provided with longitudinally extending recesses which match with recesses in abutting flanges to form channels
  • each of said ribs having a stepped form with the least dimension in the thickness (the dimension in the direction transverse to the plane of the panel) at the upper end of the rib, the greatest thickness at the lower end, and having at least one intermediate portion of intermediate thickness,
  • said concrete footings provided cantilever support for said panels and forming the sole support means for said panels, to allow said panels to yield resiliently toward the interior of the pool in response to soil pressures,
  • a swimming pool according to claim 1 characterized in that the ditference between the greatest thickness and the intermediate thickness of the rib is less than the 20 stiffening ribs are formed of form resistant foam plastic having thereon a skin of glass fiber reinforced polyester.
