Definitions

  • This invention provides a process of constructing a swimming pool basin. This invention also provides a swimming pool obtained by said process. The invention also provides pre-fabricated wall elements for constructing a swimming pool basin.
  • the sidewalls of a swimming pool basin typically consist of concrete and are constructed using formwork.
  • Polypropylene is another material known to be used in sidewalls of swimming pool basins. Neither concrete nor polypropylene can provide a satisfactory heat-insulation, resulting in high costs for keeping swimming pool water at a temperature above ambient temperature. Further, the construction of concrete sidewalls of a swimming pool basin is time consuming and requires many working steps like constructing the formwork, pouring concrete in the formwork, and demounting the formwork etc.
  • ICFs In the construction of residential buildings, insulated concrete forms or ICFs have recently been introduced.
  • walls are constructed from panels made of expanded polystyrene and concrete. The panels are erected at a distance that corresponds to the thickness of the wall. Ties between the panels keep the panels at a fixed distance. Concrete is then poured in between the panels, whereby the panels are used as formwork. As a result, walls having a 3-layer structure and good heat insulation properties are obtained.
  • ICF systems are commercially available e.g. the Quad-Lock-System (www.quadlock.com).
  • the known ICF system is, however, has disadvantages and is not suited for constructing swimming pools.
  • Second, known ICF systems are designed for the static circumstances of buildings, where walls have to stand a high pressure from upper building parts. Therefore, walls have to be very strong and concrete consumption is still high.
  • Third, heat insulation of known ICF systems may be satisfactory for buildings where heat is mainly transported to and from walls by air. In a swimming pool, however, heat is transported to the walls by water which has a much higher heat conductivity and heat capacity than air. Therefore, the insulation properties of known ICF systems is not satisfactory for a swimming pool.
  • This object has been achieved by a process of constructing a swimming pool basin, comprising:
  • a site for said swimming pool is prepared. If the swimming pool basin to be constructed is at least partially below the ground surface, said preparing may comprise making an excavation. For an above-ground swimming pool basin, said preparing may be planing or laveling the ground. If the depth of the swimming pool basin is not constant but varies along a length of the basin, said site for said swimming pool basin may be inclined accordingly. If desired, the surface of said prepared site may be tamped and provided with stoning to provide a suitable base for said swimming pool basin.
  • said pre-structure is constructed by erecting on said site a plurality of said pre-fabricated wall elements of foamed plastic.
  • said wall elements are placed on blocks like concrete blocks 82 (Fig. 9) for elevating the wall element 5 to 20 cm, preferably 10 to 15 cm, above the surface of said site.
  • Said blocks are preferably placed at a location where neighboring wall element abut each other such that one block supports the ends of two wall elements.
  • Said wall elements are placed adjacent to each other, preferably such that an even surface at the inner side of said swimming pool basin is created.
  • said wall elements preferably have means for establishing a form-fit like protrusions 26 and 56 that can establish a form-fit together with recesses 24 or 54 of a neighboring wall element.
  • Said wall elements are pre-fabricated and are made of foamed plastic.
  • the foamed plastic should be watertight.
  • said wall elements typically have peripheral portions, namely an inner wall portion 20 and an outer wall portion 16.
  • Said wall elements have a middle portion 18 where said pillar-shaped passages 12 and intervening foamed plastid portions 14 are found and may alternate.
  • the peripheral portions typically have a thickness of 3 to 8 cm, preferably 4 to 6 cm.
  • the middle portion typically has a thickness of 12 to 20 cm, preferably 14 to 17 cm (cf. Fig. 2). Most preferred dimensions of wall elements and pillar-shaped passages are given in the figures.
  • the configuration and material of said wall elements is chosen such that the wall elements provides sufficient mechanical stability to said pre-structure during the process of pouring concrete into said pillar-shaped passages. Further, the pillar-shaped passages of the wall elements are dimensioned such that the concrete pillars are of sufficient stability for the particular basin to be constructed (see below).
  • a preferred material for said wall elments is extended polystyrene (EPS), notably closed cell EPS.
  • EPS polystyrene
  • the density of the EPS is preferably at least 20 kg/m 3 , more preferably at least 25 kg/m 3 most preferably at least 30 kg/m 3 .
  • Each wall element is preferably made by foaming in a mold, whereby the shape and all surface features can be easily obtained.
  • each wall element is preferably constructed as a single piece. Methods of creating bodies of any shape e.g. by forming in a mold are known in the art (see Ullman's Encyclopedia of Industrial Chemistry (2003) Vol. 14, 553-555 and references cited
  • the wall elements of the invention have a length that corresponds essentially to the predetermined depth of said swimming pool basin. Thus, it is not necessary to place several wall elements on top of each other for reaching the predetermined height of a sidewall of the basin.
  • the invention is not limited and may be in the range of 0.5 to 3 m, preferably 1.0 to 2.0 m.
  • the other lengths of said wall element like that becoming the length in horizontal direction when said wall elements are erected may vary and may be adjusted to the overall size and shape of the pre-structure. In the case of a linear wall element, this length may be in the range of 1 to 3 m, preferably 1.5 to 2.5 m.
  • Said wall elements provide said pre-structure with pillar-shaped passages extending from top to bottom through said pre-structure.
  • Said pillar-shaped passages are filled with concrete after said pre-structure has been constructed and thus provide, after setting of the concrete, concrete pillars that provide strength to the swimming pool basin.
  • Neighboring wall elements may have recesses at the faces where neighboring wall elements abut each other when erected adjacent to each other, whereby a pillar-shaped passage may be formed by two wall elements.
  • each wall element has at least one pillar-shaped passage in said wall element (cf. Fig. 2).
  • a wall element may have several (i.e.
  • pillar-shaped passages depending on the length of said wall element (in horizontal direction after erecting the wall element).
  • Several pillar-shaped passages in the pre-structure or in a wall element are spaced by intervening foamed plastic material (cf. protions 14 in Fig. 2).
  • said pillar-shaped passages After erecting the wall element, said pillar-shaped passages extend from top to bottom, essentially in vertical direction.
  • Said pillar-shaped passages extend completely through said wall element and are open at both ends for allowing pouring in of concrete at the top and enabling a contact of poured concrete with base material at the bottom.
  • the cross-sectional shape and size of said pillar-shaped passages have to be determined such that the purpose of providing sufficient strength to the swimming pool basin can be attained.
  • An architect or civil engineer can determine the size and shape of, preferably steel reinforced, concrete pillars required for a particular swimming pool basin using his general knowledge.
  • the concrete pillars are adapted for withstanding the hydrostatic pressure of water in said basin.
  • the lower the cross-sectional areas (viewed as in Fig.
  • the cross-sectional area of the pillar-shaped passages (in the top view of Fig. 2) in the middle portion of said wall element is 40 to 80%, more preferably 50 to 70%, and most preferably 55 to 65%, whereby the remainder of the cross-sectional area is occupied by the intervening foamed plastic portion 14.
  • the horizontal cross-section (seen in the view of Fig. 2) of the pillar-shaped passages may be angular or elliptical (e.g. circular).
  • Preferred angular cross-sections are trapezium-like (as shown in Fig. 2) or rectangular.
  • the length of the edges of the square may be in the range of 10 to 20 cm.
  • the most preferred cross-sectional shape of the pillar-shaped passages is trapezoid as shown in Fig. 2. In this case, the trapezoid side having the larger dimension is oriented to the inside of the swimming pool basin, since this results in high stability for withstanding the hydrostatic pressure exerted on the wall by swimming pool water.
  • Said wall elements preferably have a U-shaped recess like recess 28 of Fig. 3 along the top side of said wall elements, said recess extending along the top side of said pre-structure.
  • Said U-shaped recess is adapted to be filled with concrete for forming an upper horizontal concrete beam resting on said concrete pillars.
  • the upper horizontal concrete beam achieves a solid, stable upper bordering of said basin.
  • the shape of the pre-structure of the invention determines the shape of the swimming pool basin to be constructed.
  • the wall elements of the invention allow to construct a swimming pool basin of any shape desired.
  • the shape of the swimming pool basin may be circular or angular, whereby such shapes may be combined to build irregular shapes of a swimming pool basin.
  • the shape of the wall elements can be adjusted to the shape of said basin.
  • the overall shape of the wall elements may be curved as those shown in Fig. 10.
  • the shape of the basin is angular (preferably rectangular) and the corresponding pre-structure is constructed from wall elements having an overall linear shape.
  • angles in the pre-structure may be formed by linear wall elements abutting each other at the predetermined angle.
  • angles in the pre-structure are constructed using corner wall elements as those shown in Fig. 5.
  • a corner wall element has two legs at the predetermined angle of the corner to be built. Each leg may have one or more pillar-shaped passages according to the invention.
  • step (iii) concrete is poured in step (iii) into the pillar-shaped passages of said pre-structure, thereby forming a plurality of discrete, spaced concrete pillars in said pre-structure.
  • Said concrete pillars provide mechanical stability and said wall elements providing heat-insulation to said basin wall.
  • the pre-structure determines the concrete structure of the sidewalls of said swimming pool basin. Then, concrete is poured in the U-shaped recess of said pre-structure, whereby, after setting, a concrete framework is obtained.
  • steel reinforced concrete should be used in said concrete pillars.
  • steel reinforced concrete is also used for said upper horizontal concrete beam in said U-shaped recession.
  • Reinforced concrete is preferably also used as a stable base under said wall elements.
  • the entire area of said basin should have a base of reinforced concrete.
  • the entire concrete structure of said basin is a structure of reinforced concrete, said structure comprising a reinforced concrete base for said concrete pillars under said wall elements, reinforced concrete pillars, and horizontal beams of reinforced concrete resting on the concrete pillars.
  • Said structure preferably further comprises a base plate of said swimming pool basin made of reinforced concrete.
  • the reinforcing steel used for the various concrete parts should be connected with each other before pouring concrete for achieving a stable structure of reinforced concrete.
  • a preferred process of constructing said swimming pool basin of the invention is as follows. After having prepared the site for said basin, steel mattresses are placed on said site, whereby the area covered with steel mattresses should be larger than the base of said basin (cf. Fig. 10). Next, said pre-structure is constructed from said pre-fabricated wall elements, whereby said wall elements are placed on blocks 82 providing a free space between the ground of said site and the bottom edge of said wall elements. Then, reinforcing steel is applied along the bottom of said wall elements in grooves 22 and 52 of said wall elements, in said pillar-shaped passages, and in said U-shaped recess.
  • the reinforcing steel parts are applied such that the steel parts in the U-shaped recess at the top of the wall elements are connected to a steel mattress at the bottom of said basin via reinforcing steel in said pillar-shaped passages.
  • These steps may be carrried out on a first day of construction.
  • concrete is delivered to the construction site by a concrete truck. Concrete is then poured into the free space under the wall elements for forming a base for said concrete pillars. Then, concrete is poured into said pillar-shaped passages. Next, concrete is poured into said U-shaped recession at the top of said pre-structure.
  • the base plate of the basin is formed by pouring concrete on the steel mattresses inside in the area surrounded by the sidewalls of the basin, whereby the swimming pool basin of the invention is obtained.
  • the concrete work can be accomplished within 3 hours.
  • the swimming pool basin of the invention may be constructed within 2 days.
  • a water inlet, a water outlet, filtering devices, pumps, heating devices of heating swimming pool water may be mounted as desired.
  • the surface of the wall elements or concrete surfaces may then be treated for achieving a more appealing appearance e.g. by painting, coating, tiling of walls or floors etc.
