The present invention provides an arrangement for interlocking adjacent shuttering slabs while allowing hinging between them to enable the shuttering to be set up in curved form. Accordingly, there is provided a method of forming a wall of a swimming pool by casting concrete into shuttering assembled on site from modular components, in which the shuttering is built up on site from elements comprising inner and outer slabs 1 or 2 assembled together in a predetermined spaced relationship, and an external face of the shuttering being formed by outer slabs which are of a thermally insulating foamed plastics material, the outer slabs being left in situ after pouring of the concrete, so as to provide a layer of thermally insulating material around the pool, wherein adjacent slabs 1, 2 on the same face of the shuttering are provided with intercalated end zones 3, 4, which are particularly castellations. The intercalated end zones 3, 4 are provided with configurations 9a, 9b to provide a through hole extending through the intercalated zones on both adjacent slabs to receive a hinge pin to secure the adjacent slabs together while allowing pivotal freedom about the hinge pin. The invention also embraces shuttering for use in such a method. <IMAGE>
Description
SPECIFICATION
Siwimming pool construction
This invention relates to the construction of swimming pools, which term may be taken to include spa pools and paddling pools of excavated type.
The now expired patent specifications GB-A1038841, GB-A-1103981 and GB-A-1103511 describe the use of shuttering elements comprising two slabs of concrete joined together in spaced relationship by cast-in tie bars. The shuttering elements are assembled together to form permanent shuttering for concrete to be poured in the construction of monolithic concrete walls for swimming pools. This method of construction has been commercially very successful for a considerable number of years.
The factory-formed shuttering elements are heavy to handle and also are difficult to transport as they are comparatively bulky, in view of the spacing between the slabs.
In order to provide a method of constructing a wall for a swimming pool using shuttering components which are lighter and less bulky to transport, our co-pending application 8432351, published under number 2162560, describes and claims a method of forming a wall of a swimming pool by casting concrete into shuttering assembled on site from modular components, in which the shuttering is built up on site from elements comprising inner and outer slabs assembled together in a predetermined spaced relationship, and an external face of the shuttering being formed by outer slabs which are of a thermally insulating foamed plastics material, the outer slabs being left in situ after pouring of the concrete, so as to provide a layer of thermally insulating material around the pool, while the inner slabs are removed after pouring and setting of the concrete.
In this method, both the inner and the outer slabs are preferably formed of a thermally insulating foamed plastics material, which may be a high density polystyrene.
The slabs of each element are conveniently held together in spaced relationship by 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.
In such an arrangement, in order to provide reasonably sound joints between the respective slabs of adjacent shuttering elements, 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 cooperating 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.
It is an object of the present invention to provide an improved arrangement for interlocking adjacent slabs while allowing hinging relative movement between them to enable the shuttering to be set up in curved form.
In accordance with a first aspect of the invention, there is provided a method of forming a wall of a swimming pool by casting concrete into shuttering assembled on site from modular components, in which the shuttering is built up on site from elements comprising inner and outer slabs assembled together in a predetermined spaced relationship, and an external face of the shuttering being formed by outer slabs which are of a thermally insulating foamed plastics material, the outer slabs being left in situ after pouring of the concrete, so as to provide a layer of thermally insulating material around the pool, wherein adjacent slabs on the same face of the shuttering are provided with intercalated end zones, the intercalated end zones being configured to provide a through hole extending through the intercalated zones on both adjacent slabs to receive a hinge pin to secure the adjacent slabs together while allowing pivotal freedom about the hinge pin.
The intercalated end zones are preferably formed by the slabs having castellated end portions.
Preferably, the castellations are each provided with a recess extending from either the inner or the outer face, the recesses at any one junction being essentially in a common vertical plane and the recesses extending from the outer face overlapping with those extending from the inner face to provide the said through hole. The castellations at a junction may interfit so as to provide abutment between the ends of the slabs, with one face at any zone of abutment being cut away or chamfered to allow limited pivoting.
In a modified form of the invention, each slab is provided with a arrangement of double staggered castellations to interfit with an end of the adjacent slab, with the castellations terminating in a common plane intermediate the thickness of the slab, and the faces of the castellations in the said intermediate plane being formed with configurations to accommodate the hinge pin. Such configurations are preferably grooves co-operating with corresponding grooves on the opposing corresponding face of the adjacent slab to form a part of the through hole for the hinge pin.
In accordance with a second aspect of the invention, there is provided shuttering for a swimming pool construction, the said shuttering being built up on site from elements comprising inner and outer slabs assembled together in a predetermined spaced relationship, and an external face of the shuttering being formed by outer slabs which are of a thermally insulating foamed plastics material, wherein the slabs are provided with castel lated end zones adapted to interfit with the end zones of adjacent similar slabs, the castellations being configured to provide a through hole extending through the castellations on both adjacent slabs to receive a hinge pin to secure the adjacent slabs together while allowing some pivotal freedom about the hinge pin.
Preferably, the castellations are each provided with a recess extending from either the inner or the outer face, the recesses at any one junction being essentially in a common vertical plane and the recesses extending from the outer face overlapping with those extending from the inner face to provide the said through hole.
Preferably also, the castellations at a junction interfit so as to provide abutment between the ends of the slabs, with one face at any zone of abutment being cut away or chamfered to allow limited pivoting.
In accordance with a further aspect of the invention, there is provided 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.
The invention will be further described with reference to the accompanying diagrammatic drawings, in which:
Figure 1 is a partial sectional view showing shuttering of the general type to which the present invention relates;
Figure 2 is an elevation of one shuttering slab in accordance with the invention and part of an adjacent one, shown somewhat spaced for clarity of illustration; and
Figure 3 is a section taken on the line Ill-Ill of figure 2, with the slabs in juxtaposed relationship; and
Figure 4 is a perspective view showing parts of two adjacent slabs in a modified form of shuttering.
Figure 1 shows part of a composite shuttering element comprising a pair of spaced slabs 1 interconnected by tie-bars 11. Each slab is of high density expanded polystyrene for strength and thermal insulation. Fitted over the end of each tie-bar is a disc 12 secured by a holding pin 13. Vertical starter reinforcement bars 14 are supported by the tie bars 12 and horizontal starter reinforcement bars 15 are supported by the bars 14. The tie-bars are shown as having points of weakness 16, so that they may be broken off when the inner slabs are removed after pouring.
This type of shuttering is more fully described in our GB-A-2162560.
Figures 2 and 3 show two adjacent slabs 1 and 2 to form shuttering of this type. It will thus be appreciated that each slab 1 and 2 is one of a pair of slabs held in spaced and parallel relationship by tie bars. At their adjacent edges, the slabs have intercalated castellations 3 and 4 respectively. When the slabs are joined up to form shuttering or formwork, the ridged ends 5 of each castellation abuts the base 6 of the space between the adjacent castellations, so that the ridge 7 forms a pivot axis and the clearances allow limited pivoting to enable the formation of curved walls.
In order to link the adjacent slabs by means of a hinge pin 8-, each castellation 3 and 4 is provided with a vertical recess extending for slightly over one half of the depth of the castellation. The recesses are of two kinds as illustrated, some recesses 9a open upwardly from the plane of figure 2, while the other recesses 9b open in the oposite direction.
It will be seen from figure 3 that the recesses overlap somewhat and the common area, when viewed vertically, forms a suitable housing for the hinge pin 8, which mechanically links the slabs 1 and 2 and allows the required limited pivoting movement.
In the alternative and improved arrangement of figure 4, each slab la and 2a is provided with a double set of castellations 21, 22 which are staggered and interfit with the castellations 22, 21 on the adjacent slab. It will be seen that the thickness of the castellations is approximately half of the thickness of the slab, and that the inner faces of the castellations 21,22 on any slab are all in a common plane intermediate the thickness of the slab, in the example given half way through. Each of the siad inner faces is provided with a substantially semi-circular section groove 24. All the grooves 24 are aligned and co-operate with the grooves in the inner face of the adjacent slab to form a through hole to receive a hinge pin 25 introduced when the slabs 1a, 2a are assembled together to lock the slabs together while allowing relative hinging.
It will also be seen from figure 4 that the slabs la and 2a are provided with longitudinal ribs 26 which are provided to interfit with corresponding grooves in a subjacent or superjacent slab or, as shown in figure 4, in a foundation element 27.
Various modifications may be made within the scope of the invention.
