Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in the structure of a prefabricated pool.

In general, dirt tends to accumulate near the ends of the short sides of swimming pools. This is used on the long side and on the short side for making turns, resting, or getting in and out of the pool. Therefore, in order to reduce contamination on the short sides, it is preferable that the bottom is not flat, but rather sloped so that it becomes deeper toward the center in the long side direction. In a prefabricated pool, a pool having a predetermined shape and size is formed by connecting segments to each other, but in this case, it is desirable to minimize the number of types of segments from the viewpoint of cost. On the other hand, in order to prevent the above-mentioned stains, it is preferable that the bottom of the pool be sloped into a V-shape that becomes deeper toward the center or an inclined surface that gradually becomes deeper from one side to the other. increases, resulting in a cost disadvantage.

This invention has been made to solve these conventional drawbacks, and provides a prefabricated pool in which there are fewer types of segment shapes and dirt is less likely to accumulate on the short sides of the pool. . That is, the present invention provides a prefabricated pool in which a bottom wall segment and a peripheral wall segment are connected to form a substantially rectangular pool in plan view, and the bottom near both ends in the length direction of the pool is deeper on the center side in the length direction of the pool. The longitudinally central bottom of the pool is defined by at least one horizontal bottom wall segment between the inclined bottom wall segments. The circumferential wall segments near both widthwise ends of the pool are formed to be inclined in accordance with the inclination of each bottom wall segment so that the bottom wall portion thereof is butt-coupled to each of the bottom wall segments. It is something that exists.

Hereinafter, an embodiment in which the present invention is applied to a prefabricated pool made of fiber reinforced plastic (hereinafter referred to as FRP) will be described with reference to the drawings. In Figures 1 and 2, 11, 12, 13, 14, and 16 are side wall segments, and 15, 17 are bottom wall segments, and a large number of these segments are connected to each other to form a prefabricated pool with a rectangular planar shape. has been done. In terms of the side shape of the pool, the length direction of the pool,
In other words, the left-right direction in Figures 1 and 2, which is the direction in which a person swims (hereinafter, this direction is referred to as the length direction)
Segment 15 in area A at the center of is installed horizontally, and area B at both ends (both short sides) in the length direction
The bottom wall segment 17 of the pool is installed so as to be inclined in the length direction with respect to the horizontal plane, and the pool is configured such that the central area A in the longitudinal direction is deep, and the areas B on both end sides become gradually shallower toward the ends. ing.

The bottom of the pool is in the direction perpendicular to the paper in Figure 2.
That is, the pool is formed horizontally in the width direction, so that the bottom surface of the pool is sloped only in the length direction of the pool, and is not sloped in the width direction of the pool. 18 is the stairs for entering and exiting the pool, 19
is a handrail. In addition, the pool has a drainage pipe 51.
are connected to both sides of the bottom, and a drain pipe 52 for discharging overflow water is led from the corner of the pool to a pit 55, and the water in the pit 55 is passed from a pump 54 through a filter 53 to a purified water supply pipe to the side of the pool. 56.

Usually, pools tend to get dirty because people often stay on the short sides, such as when people go in and out or take turns, but in the above configuration, the bottom wall is gradually deepened toward the center. The sediment accumulated at the bottom of the short side ends gradually moves to the center in the length direction of the pool on the sloping bottom surface, and as a result, the vicinity of the lengthwise ends (short side ends) Dirt is reduced. In addition, in prefabricated pools, the number of segments increases or decreases depending on the length of the pool, but if the bottom wall is all sloped so that it gets deeper towards the center, the types of segments will increase depending on the number of segments. . If the central area A is made flat as described above, the segments in this area can be of the same type, and if the length is adjusted in this area, the number of segments will increase. This is extremely advantageous in terms of cost since it is sufficient to use segments of the same shape.

As shown in FIGS. 3 and 4, the side wall segment 13 is formed by integrally forming the side wall 1 and the end bottom walls 3 and 4 with FRP, and the bottom wall 3 has the same slope as the sloped bottom wall segment 17. The bottom wall 4 is formed horizontally in correspondence with a central horizontally arranged bottom wall segment 15 . The inclined bottom wall segment 17 and the horizontal segment 15 may be flat plates made of FRP or the like, and the former is arranged inclined and the latter is arranged horizontally. Further, these peripheral portions may adopt a known shape that allows for a sealing structure with adjacent members, such as by fitting the concave and convex portions.
Further, an overflow groove 20 is integrally formed in the upper part of the side wall 1, and a lattice-shaped lid 2 is attached to the upper surface of the overflow groove 20 to form the edge of the pool.

The side wall segments are connected to each other, the bottom wall segments are connected to each other, and the bottom wall segments and the bottom walls of the side wall segments are connected by abutting their respective side end surfaces using a known connection structure. Furthermore, the butt-joining position of the longitudinal ends of the bottom wall segments is located in the middle of the side wall segments, so that the joining position of the side wall segments and the joining position of the bottom wall segments do not overlap. (so that the bond lines do not intersect in a cross shape). By arranging the connecting portions between the side wall segments and the connecting portions between the bottom wall segments at different positions in this manner, the joining structure can be simplified compared to one in which the connecting portions intersect in a criss-cross pattern. This is because at a cross-shaped intersection, it is necessary to stack four members at the joint in order to ensure a seal at that part, but if the positions of the joints are shifted from each other as shown above, the four members overlap. There is no need for overlapping, the structure is simplified, and the reliability of sealing can be improved.

5 to 7 show side wall segments at the corners, which have a complicated configuration due to the formation of the outlet 21 of the overflow groove 20 and the sloped sides of the overflow groove 20. That is, the corner side wall segment 11 has an outlet 21 formed at the corner, and overflow grooves 20 are formed on both sides thereof in directions perpendicular to each other.
One overflow groove 20 is formed by a bottom wall 24 and sloped walls 25 and 26 parallel to each other, and the other overflow groove is formed by a bottom wall 24 and sloped walls 27 and 28 that are opposite to each other and are formed to open upward.
Further, on the end side of the inclined walls 27 and 28, there is a triangular inclined wall 31 which spreads downward.
32 is formed. The purpose of sloping the overflow groove 20 outward is to reduce the sound of water in the pool as it overflows and flows into the overflow groove. Slanted walls 31, 32
was formed by the adjacent sidewall segment 16
This is to match the position and shape of the overflow groove and the connecting part of the segment 11, and the die cutting of the segment 11 is carried out by moving the die in the direction of the arrow in FIG. At this time, the inclined walls 27 and 28 are made to widen upward so that the other overflow groove can be punched out.
When such a structure is adopted, the corner side wall segments having mutually orthogonal inclined overflow grooves 20 can be integrally formed by molding.

As explained above, in the present invention, the pool is formed so that it becomes gradually deeper in the long side direction from the short side end toward the center, and an area of uniform depth is formed in the center. This prevents contamination on the short sides and allows pools of various lengths to be accommodated without increasing the number of segment shapes. That is, first of all, the ends of the short sides are prevented from getting dirty. Because people stay at the short end while turning, etc., sediment that causes dirt tends to form, and if the bottom of the pool is sloped, this sediment will move deeper. Therefore, if the bottom wall is inclined so that it becomes deeper toward the center, the sediment will also move toward the center, thereby reducing the contamination at the shallow end portions of the short sides. Second, although the length of the pool varies, it can be easily and inexpensively accommodated. In other words, if you tilt the entire pool so that it gets deeper towards the center of its length,
Since the side wall segments (peripheral wall segments) in the width direction of the pool are formed with different shapes (depths), many types of segments are required depending on the length of the pool (number of segments used). Become. However, if a horizontal part is formed in the center and the length of the pool is adjusted by increasing or decreasing the number of segments in the center, the number of types of segments will increase because the segments in the center only need to be of the same shape. There is no need for it, making it easier and cheaper to handle.
