DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

This invention relates to a pool or other liquid storage container and method of making the same.
A known type of swimming or ornamental pool has a substantially flat bottom, which may be of free-form shape, made of sheet material, and having secured and sealed about its periphery an extruded metal section formed with a horizontal groove to receive the edge of the pool bottom and also a sealing strip, and also formed with a vertical groove to receive the bottom edge of the wall of the pool. The pool wall consists of a section of pliable sheet material which may be rolled up for delivery to the site, and of which the ends are then secured together to form an endless loop. The bottom edge of the wall section is sealed in the vertical groove of the extrusion about the periphery of the pool bottom by a round-section sealing strip driven between a side of the groove and the inserted part of the wall. The pool bottom is bedded on sand, an extruded stiffening strip is applied about the top of the pool wall, and concrete is poured about the pool wall, within the excavation for the pool.
Pools of this type have been generally satisfactory, being capable of being made in a very wide variety of configurations in plan view. A disadvantage has been found in difficulties experienced in bending to shape the extrusion applied about the periphery of the pool bottom while retaining its cross-sectional configuration undistorted, and particularly in maintaining the sides of both the horizontal and the vertical groove consistently parallel and uniformly spaced.
The present invention has been devised with the general object of providing a pool or other liquid storage container having a similar flexibility of contour, but which is particularly simple and economical to make and install.


BRIEF SUMMARY OF THE INVENTION

Accordingly, the invention resides broadly in a method of making a pool or other liquid storage container including the steps of supporting an endless base strip with its upper edge substantially in a horizontal plane; applying an endless former strip of resiliently deformable material about the base strip, the top of the former strip being above the top of the base strip; applying concrete to embed therein the base and former strips, concrete inwardly of the base strip being substantially level with the top of this strip, concrete outwardly of the former strip being above the level of the base strip; removing the former strip after the concrete has set to form an endless groove of which the base strip forms the inside face; inserting into this groove the bottom part of a container wall consisting of an endless loop of vertical sheet material; and force-fitting a sealing strip of resiliently deformable material into the groove between the base strip and the inserted bottom part of the wall. The invention also resides in a pool or other storage container made according to the method above set out.


BRIEF DESCRIPTION OF THE DRAWINGS

In the drawings:
FIG. 1 is a partly broken-away perspective view of a pool according to the invention;
FIG. 2 is a sectional view to larger scale of a part of the pool during the course of its construction;
FIG. 3 is a sectional view to the same scale as FIG. 2, taken along line 3--3 in FIG. 1;
FIG. 4 is a sectional view, to further enlarged scale, along line 4--4 in FIG. 1, showing the sealed connection of the ends of the pool wall section; and
FIG. 5 is a sectional view showing an alternative sealed connection of the ends of the pool wall section.


DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The pool illustrated is of in-ground type, and an excavation is made somewhat larger than the contour of the pool to be installed, the excavation having a substantially flat level bottom.
An extruded metal base strip, of aluminium for example, has its ends connected to form an endless loop which is shaped to the configuration of the pool to be made and is supported above the excavation bottom by blocks 11 so that it is level. The base strip 10 is disposed verti
