Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prefabricated swimming pool in which the side walls of the swimming pool are constructed by arranging a plurality of standard sized structural members adjacent to each other.

It is possible to construct a swimming pool by erecting a side wall for the swimming pool in the root cutting during foundation construction, and then installing a flexible waterproof metal sheet to retain water in the swimming pool. Usually done. It is also conventional practice to construct side walls of swimming pools by assembling a number of standardized structural members constructed from sheet metal or other suitable material, such as plastic; for example, in U.S. Pat. Already known from No. 3015191, No. 3059243 and No. 3094709. In the latter case, the upper and lower ends of the thin plates of each structural member are bent horizontally toward the outside of the side wall to form a horizontal flange in order to strengthen the steel of the side wall. When constructing a swimming pool side wall with a curved surface in the latter prefabricated swimming pool, the side wall structure portion of the thin plate of each structural member must be constructed into a curved surface with a desired curvature. In such cases, it is difficult to form horizontal flanges at the upper and lower ends of the thin plate, requiring a relatively large amount of cost and time to manufacture.

It is also conventional to construct a storage tank from a plurality of standardized plates, and such a storage tank is described in US Pat. No. 1,076,382. In this case, the edges of each plate are stepped outwards to form reinforcing flanges. The reinforcing flanges at the edges of adjacent plates are overlapped with each other so that they do not protrude too much into the inner surface of the storage tank,
Such a structure is also shown in US Pat. No. 2,123,035. It is also common practice to construct containers from a plurality of standardized units, in which mutually overlapping edges of mutually adjacent units are provided with recesses for receiving fastening members.

The various conventional examples described above are designed only for special uses, and are difficult to apply directly to prefabricated swimming pools.

This invention was made based on the above circumstances, and an object of the invention is to create a side wall of a swimming pool in which all of the standardized structural members have the same structure, and which have an arbitrary planar shape. Therefore, it is possible to construct a side wall of a swimming pool having a substantially smooth inner surface without creating a portion that protrudes inwardly from the inner surface of the side wall, and is easy to assemble. To provide a prefabricated swimming pool that is easy to clean and has high strength.

To achieve the above objects, in a prefabricated swimming pool according to the invention: each structural member has an integral vertical flange extending generally vertically and projecting outwardly from the side wall; each structural member has a flexible thin plate having one end thereof; each structural member has a substantially vertically extending step stepped outwardly at one end of the thin plate to a depth approximately equal to the thickness of the thin plate; and the other end of the thin plate in the horizontal direction overlaps the inner surface of the stepped portion of one end of the thin plate of an adjacent structural member; and the overlapping region of the other end are both provided with recesses further recessed outward; the stepped portion of one end of the thin plate of each structural member and the overlapping region of the other end, respectively The recess at the other end of the thin plate of the adjacent structural member that overlaps the stepped portion at the one end overlaps the overlapping region of the other end of the thin plate of another adjacent structural member. It is engaged in the horizontal direction with a recess in the stepped portion of one end; and the recess in the overlapping region of the other end of the thin plate of each structural member is engaged with the recess of the thin plate of the adjacent structural member. In the recess of the stepped portion at one end, a headed fastening member is arranged such that the head of the fastening member is disposed within the recess of the overlapping region of the other end located on the inner surface side of the side wall. The overlapping region of the other end of the thin plate of each structural member and the overlapping recess of the stepped portion of one end of the thin plate of the adjacent structural member are thereby interconnected. the member and an adjacent structural member are interconnected; the head of the headed fastener is disposed within a recess in the overlapping region of the other end located on the inner surface side of the side wall; This is characterized in that the inner surfaces of the side walls constituted by a plurality of mutually connected structural members are arranged in the same plane and constitute a smooth continuous surface.

In this case, each structural member is composed of a flexible thin plate, and the flange for reinforcing the side wall component of the thin plate extends approximately vertically and projects outward from the side wall. can be easily bent to a desired curvature to form a swimming pool sidewall with a desired planar shape.

In a prefabricated swimming pool according to the present invention, the thickness of the lamella at the other end of the lamina of each structural member which is not provided with a vertical flange and the thickness of the lamina at one end where the lamina of an adjacent structural member is provided with a vertical flange is also provided. overlaps the inner surface of the stepped portion which is stepped outwardly and extends substantially vertically to a depth substantially equal to the depth of The other end of the lamina of each structural member does not create an inward bulge on the inner surface of the side wall of the swimming pool formed by the plurality of interconnected structural members.

In addition, the above-mentioned recesses further recessed outward are provided in both the stepped portion at one end of the thin plate of each structural member and the overlapping region at the other end, so that the stepped portion at one end of the thin plate of each structural member The respective recesses in the overlapping regions of the ends overlap with the recesses in the other end of the thin plate of the adjacent structural member that overlaps the stepped portion of the one end, and another recess in which the overlapping region of the other end overlaps. The other lamellae of each structural member are engaged in the horizontal direction with a recess in the stepped portion of one end of the lamellae of the adjacent structural member to interconnect the respective structural member and the adjacent structural member. a headed fastening member for interconnecting the overlapping region of the end portions and a stepped portion of one end of the thin plate of an adjacent structural member; It is inserted in the outward direction while being disposed within the recess of the region.

The recesses in the overlapping areas of the other ends of the laminae of the respective structural members engaging each other and the recesses in the stepped portions of one end of the laminae of the adjacent structural members also define the recesses of the swimming pool after assembly. a headed fastening member that does not create an inward bulge on the inner surface of the side wall and is located within a recess in the overlapping region of the other end, the head of which is located on the inner surface side of the side wall; also does not create an inward bulge on the inner surface of the swimming pool side wall after it is assembled.

That is, the stepped portion and the recess make it possible to form a side wall of the swimming pool with a substantially smooth inner surface.

A recess in the overlapping region of the other end of the thin plate of each structural member to be mutually engaged and a recess in the stepped portion of one end of the thin plate of the adjacent structural member are used to connect a plurality of structural members to each other by means of a fastening member. It facilitates the assembly of prefabricated swimming pools by allowing multiple structural members to be arranged to form a swimming pool sidewall with a desired planar shape before being joined to the structure. It also contributes to the transmission of force between members and prevents excessive stress from being applied to the fastening members, thereby improving the strength of the prefabricated swimming pool.

In addition to the above-mentioned objects, it is a further object of the present invention to provide a concrete apron support structure of simple construction in a prefabricated swimming pool of the construction as described above, which achieves the above-mentioned objects.

It is characterized by the fact that the concrete reinforcing rods are buried inside the concrete apron.

Here, the vertical flange is used not only as a support member for supporting concrete reinforcing bars for a concrete apron, but also as an apron support member.

In order to achieve further objects of the invention as described above, in a prefabricated swimming pool constructed as described above, the upper surface of the concrete apron is provided with a structure extending in a vertical plane including the vertical flanges of each structural member. It is preferable that a groove is formed.

In a concrete apron where such a groove extends, the vertical plane including the vertical flange is the weakest part of the concrete apron, so if cracks occur in the concrete apron, Even if the crack is located in the weaker part (i.e.,
(the vertical plane comprising the groove and its corresponding vertical flange) and is prevented from advancing into other areas in the apron bounded by the groove.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The plan view of FIG. 1 shows the assembled side wall 2 of the prefabricated swimming pool and the concrete apron 4 extending horizontally outward from the upper edge of the side wall 2. As shown in FIG. 1, the side wall 2 is composed of a continuous linear section and a plurality of curved sections 6 having various curvatures. In this embodiment, the side wall 2 of the swimming pool has a planar shape as shown in FIG. 1, but according to the present invention, the side wall 2 can have any planar shape.

As shown in FIGS. 2 and 3, each of the plurality of standard-sized structural members making up the side wall 2 is formed of metal or other suitably flexible material. It has a flat thin plate 8 that stands up substantially vertically. One horizontal end of the thin plate 8 forms a vertical flange 10 which is bent outward at a substantially right angle to the side wall component of the thin plate 8 and extends substantially vertically. An outer edge portion of the vertical flange 10 extending in a substantially vertical direction is bent substantially parallel to the side wall 2 to form a narrow reinforcing flange 12.

The lamina 8 of each structural member is formed with an outwardly stepped step 14 in the vicinity of the vertical flange 10, as shown in FIG. The stepped portion 14 is continuous from the upper end to the lower end of the thin plate 8 and has a depth approximately equal to the thickness of the thin plate 8.

The other horizontal end portion of the thin plate 8 of another structural member adjacent to the other structural member, where the stepped portion 14 is not formed, overlaps. The stepped portion 14 of the lamella 8 of each structural member and the other end of the lamella 8 of an adjacent structural member overlapping the stepped portion 14 are provided with further outward recesses in the mutually overlapping region. Recesses 16 and 18 are formed. These recesses 16 and 18 are formed by forging such that the recess 16 of the stepped portion 14 of one end of the mutually adjacent structural member contains the recess 1 of the other end.
8 can be tightly fitted together, the plurality of structural members can be assembled in advance to form the side wall 2 of a desired planar shape even before the plurality of structural members are firmly connected to each other by the fastening member 20 described later. I can do it.

In this embodiment, the fastening member 20 is composed of a headed bolt and a nut screwed into the bolt, and the headed bolt has its head attached to the inner surface of the side wall 2, as shown in detail in FIG.

As shown in particular detail in Figure 2, concrete (not shown) for the foundation is poured, and after the earth and sand that had been removed for the installation of the swimming pool has been returned to its predetermined position, the concrete for forming the apron 4 is poured. Concrete is poured. An elastic edging member 28 is then engaged with the upper edges of the structural members, in particular with the upper edges of the lamellas 8 . The edging member 28 has an engagement flange 30 on its upper edge for fixing the edging member 28 to the concrete apron 4 as shown in FIG. Note that the edging member 28 may have a different shape from that illustrated, and may be provided by a different method from that illustrated.

As shown in particular detail in FIG. 2, the upper ends of the vertical flanges 10 of each structural member are embedded in the concrete apron 4 together with concrete reinforcing rods 24.

The upper surface of the apron 4 is formed with a plurality of grooves 32 extending in a vertical plane that includes the vertical flange 10 of each component. The plurality of vertical planes including the plurality of grooves 32 and the plurality of vertical flanges 10 constitute weak parts in the apron 4, and cracks occurring in the apron 4 between two adjacent grooves 32 are When it reaches the groove 32, it will proceed on the groove 32 along the weaker part of the apron 4, and will not proceed in the apron 4 beyond the space between two adjacent grooves 32.

As shown, the inner surface of the side wall 2 of the swimming pool is overlaid with a flexible liner 34 which also covers the concrete bottom wall of the swimming pool. The liner 34 constitutes a water retention member for retaining water in the swimming pool. The liner 34 has a bead 3 as shown in FIG.
6, the bead 36 engages a recess formed in the edging member 28. Further, as shown in FIG. 4, a reinforcing plate 38 made of steel is provided on the edging member 28 adjacent to the bead 36, but the reinforcing plate 38 is irrelevant to the gist of the present invention.

As shown in FIG. 2, the lower ends of a plurality of braces 40 are fixed to the lower ends of each vertical flange 10. As shown in FIG. The brace 40 extends obliquely upward from the side wall 2 in an outwardly inclined state, and its upper end is buried in the apron 4. As shown in the figure, the upper end of each brace 40 also extends from the apron 4.
