Definitions

  • This invention relates to the construction of swimming pools.
  • tapping pool is intended to comprehend not only pools for swimming in the strict sense of that term, but also paddling pools, Jacuzzis and similar constructions.
  • a method of forming a wall of a swimming pool by casting concrete into shuttering assembled on site from modular components, in which the modular components of the shuttering are built up on site from elements comprising inner and outer slabs assembled together in a predetermined spaced relationship, and in which at least an external face of the shuttering is formed by the outer slabs which are of a thermally insulating foamed plastics material.
  • shuttering assembled on site from modular components for the casting of a swimming pool wall, in which the modular components of the shuttering are built up on site from separable elements comprising inner and outer slabs assembled together in a predetermined spaced relationship, and in which at least an external face of the shuttering is formed by the outer slabs which are of a thermally insulating foamed plastics material.
  • both the inner and the outer slabs are formed of a thermally insulating foamed plastics material, which may be a high density polystyrene.
  • the outer slabs are preferably left in situ after pouring of the concrete, so as to provide a layer of thermally insulating material around the pool.
  • the inner slabs may be removed after pouring and setting of the concrete, and deposited outside the outer slabs prior to back--filling the cavity outside the outer slabs.
  • tie bars which may be of plastics material.
  • the tie bars may each be provided with a frangible zone to enable them to be broken off substantially flush with the exposed concrete face when the inner slabs are removed.
  • the slabs may each have at least one edge , which is normally a generally vertical edge, presenting a longitudinal recess, while the opposite edge is provided with a projection co-operating with the said recess on an adjacent similar slab to allow some angular relative movement without detriment to the effect of the seal between the abutting edges.
  • a wall of a swimming pool when formed by a method according to the invention as set forth above, or when cast in shuttering according to the invention as set forth above.
  • a typical shuttering element is shown as comprising a first slab or block 11 and a second slab or block 12 which are interconnected by tie bars 13.
  • Each of the blocks 11 and 12 is of high density expanded polystyrene to give it substantial strength and also thermal insulation properties.
  • the block 11 is shown as being somewhat shorter than the block 12 and the ends 14 of the blocks are shown as being inclined.
  • the tie bars 13 are of a suitable plastics material and pass through pre-formed passages in the blocks 11 and 12 so as to extend somewhat beyond the outer surface of each of these blocks. Fitted over each of the ends of each tie bar 13 is a disc 15 which is held in place by means of a holding pin passing through an aperture 16 which is provided in each end of each tie bar 13. Only one of the apertures 16 is shown for each tie bar 13 in figure 1.
  • the tie bars 13 are a light interference fit in pre-formed apertures in the blocks 11 and 12 so that the latter remain in position on the tie bars during assembly.
  • Figure 1 also shows how the tie bars 13 can be used for location of vertical reinforcement bars 17 of high tensile steel, and these vertical bars 17 may themselves be used to support horizontal reinforcing bars 18, also of high tensile steel. These reinforcing bars 17 and 18 are in a cavity 19 defined within the shuttering formed by the assembled elements.
  • Figure 1 shows parts of adjacent elements. It will be seen that the block 12 is adjacent a block lla similar to block 11, but reversed, on either side, and the block 11 is itself adjacent to blocks 12a, again similar to the blocks 12 but reversed.
  • the adjacent faces 14 of the blocks 11 and 12a and 12 and 11 a are shown as being spaced, but in practice they will abut quite closely together when the blocks are in alignment, and so will form an effective seal.
  • a suitable adhesive may be applied between the abutting faces 14 to solidify the shuttering.
  • adhesive may be provided between the adjacent horizontal faces of the blocks.
  • the blocks 11 and 12 may each be 1 foot (30 cm) high by approximately 2 feet (60 cm) long by 2.5 inches (6 cm) thick.
  • the spacing between blocks, i.e. the width of the cavity 19 may be 6 inches to 8 inches (15 to 20 cm).
  • the arrangement described above is for forming straight walls. Where a wall has to have a curve, the arrangement is that the longer blocks 12 are arranged around the outside of the curve while the shorter blocks 11 are in the inside.
  • the radius can be varied from the minimum, in which all the inner blocks are short blocks 11, by having some of the blocks on the inner side longer blocks or some of the blocks on the outer side shorter.
  • the concrete is poured into the cavity 19 and vibrated and allowed to set.
  • the blocks on the internal face will be removed so as to present a concrete face for rendering and tiling (or application of other alternative surface finish) on the inner surface of the pool.
  • the outer surface formed by the blocks 11 and 12a will remain in position and since it is formed of thermally insulating material, its presence will reduce the amount of heat lost from the pool into the surrounding ground.
  • the used blocks from the inner face may be disposed of as part of the back-fill material within the excavation outside the blocks 11 and 12a if appropriate. This will tend to assist in thermal insulation, and reduce the amount of soil in-filling which is necessary.
  • the pool is normally constructed by excavating rather more than the total pool area and then building the pool wall slightly inside the outer perimeter of the excavation. Surplus space then has to be back-filled using aggregate or hardcore, and the use of the discarded blocks for this purpose is, therefore, possibly advantageous.
  • the tie bars When the blocks lla and 12 are removed by releasing the locking pins and withdrawing the discs 15 and then pulling the blocks away from the formed wall, the tie bars are left projecting. In order to enable the tie bars to be readily broken off, they are provided with cutaways to provide zones of weakness in the region of the points 21 so that they may be broken off substantially flush with the wall.
  • FIG 2 there is shown an arrangement by which slabs or blocks 22 and 23 are assembled together using H form clips 24 with integral tie bars 25.
  • the clips 24 fit over the upper surfaces of the blocks and receive the lower parts of the superjacent blocks to hold them together.
  • the clips may again be of plastics material, and those for at least the blocks to be removed may be made frangible, by providing weakened zones in order that the clip will not project from the formed concrete wall.
  • the inner wall i.e. the pool side of the shuttering may remain in position, and if this is done, then a lightweight aggregate can be used for this face rather than the plastics material. In such a case, the exposed face of the shuttering would be rendered after pouring and setting of the concrete.
  • the tie bars since no provison has to be made for removal of the protruding part of the tie bar, it may be preferred for the tie bars to be set into blind holes such as 26 on the inner face of a light aggregate slab or block, and use may then be made of a disc and securing pin arrangement at the other end of the tie bar to hold the outer surface thermally insulating plastics block.
  • the individual slabs may be made in large sizes, e.g. approximately 4 feet (120 cm) high by 2 feet (60 cm) long.
  • An arrangement of two elements of large size slabs 31 and 32 is shown in figure 3.
  • the tie bars are shown at 33.
  • the vertical edges 34 and 35 respectively of the slabs are convex and concave respectively, when viewed in horizontal section, so as to present projections and matching recesses to improve the seal between adjacent slabs, and also to enable the slabs to take up different relative angular positions without affecting the seal between them in any adverse way.
  • the building up of arcuate or radiussed walls is thus assisted.
