Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an assembled pool for swimming in which a plurality of side plates and bottom plates are joined together and an overflow groove is formed on the inner peripheral surface.

F. R. Assembled swimming pools, in which side panels and bottom panels made of P (reinforced plastic) are pre-produced in a factory and assembled by sequentially joining the required number of side panels and bottom panels at the installation site, are conventionally used in small pools. Or, since it was considered as a simple pool, structures such as overflow grooves were not adopted.

However, even in this type of pool, it is possible to construct a larger pool by increasing the number of side plates and bottom plates, and thus the need for an overflow groove has been met. The overflow groove allows debris, hair, and other floating objects floating on the water surface of the pool to overflow, and
It is desirable that the pool be provided continuously around the entire circumference of the pool, as it provides a place for swimmers to throw away their grandchildren and saliva, and also has the effect of erasing the waves generated while swimming. Moreover, the side plate is F. R.
Since it is molded from P, it is desirable that the overflow groove is also formed integrally with this side plate and simultaneously molded. However, since the corners of this type of pool are formed into curved surfaces for strength and aesthetic reasons, it is not possible to make the draft angle of the product mold zero when forming an overflow groove along the curved surface. There was an inconsistency that made it difficult to integrally form a smooth overflow groove.

This invention was made based on these circumstances,
The purpose of this is to create an assembled pool with an overflow groove that allows a smooth-shaped overflow groove to be integrally formed on the side plate at that position even if the corner is formed into a curved surface. This is what we are trying to provide.

That is, the present invention divides a side plate located at a corner at an angular position that is half the bending angle of the corner, so that these divided pieces abut each other, and each of these divided pieces The overflow groove in the side plate is uniformly continuous across the straight section of the inner surface of the side panel, and the curved section connected to the straight section of the bracket is continuous with the straight section of the side panel. It is characterized in that the same cross-sectional shape as the cross-sectional shape of the part is shifted in parallel along the above-mentioned curve, and the cutting slope is zero.

An embodiment of the present invention will be described below with reference to the drawings.

R. A side wall portion 3 formed of P (reinforced plastic) and a core material 5a such as a foamed urethane resin extending horizontally from the lower edge of the side wall portion 3 are formed of F. R. It has a bottom wall portion 4 covered with P5b. Further, in the bottom plate 2, like the bottom wall portion 4 of the side plate 1, a core material 5a such as foamed urethane resin is used. R. It is coated with P5b. As shown in FIG. 3, a butt joint flange 6 is integrally formed on the edge of the bottom wall 3 of the side plate 1, and a lap joint flange 6 is formed on the periphery of the bottom wall 4. Portions 7a and 7b are formed.

The lap joint flange of the bottom wall portion 4 is connected to the adjacent side plate 1,
As shown in FIG. 6, one of the flange portions 7a is configured to be on the lower side, and the other flange portion 7b is on the upper side, so that they cannot overlap each other vertically. It is now possible to do so. Flange portions 8a and 8b (only one is shown) are provided on the periphery of the bottom plate 2 to be overlap-joined to the lower and upper flange portions 7a and 7b for overlap-joint of the bottom wall portion 4 of the side plate 1, respectively.

In this way, in the assembled pool, a flange-shaped coping 17 extending outward horizontally is provided at the upper end of each side plate 1.
are integrally formed, and these copings 17 are connected to each side plate 1.
When assembled as shown in Figure 1, it forms a continuous deck that extends all around the open green of the pool.

An overflow groove 18 is formed at a position below the coping 17.

This overflow groove 18 is formed integrally with each side plate 1..., and when these side plates 1... are connected to each other, it is configured continuously over the entire circumference of the inner surface of the pool. . This overflow groove 18 is formed as shown in detail in FIG. In other words, the overflow groove 18 has the entrance part 19 on the inner surface of the side plate 1, and the inner part 20 thereof is inclined outwardly and downwardly. The groove side surfaces 21a and 21b are formed parallel to each other so that the closing middle of the entrance portion 19 and the groove width 12 of the inner portion 20 are the same. In this embodiment, the overflow groove 18 has the above-mentioned inclination angle 8 at an angle of 45 degrees with respect to the vertical line H-H'. Further, the lower opening green 19a in the opening □ portion 19 of the overflow groove 18 is slightly protruded inward compared to the upper lip edge 19b.In other words, the upper closing green 19b is sunk deeper than the inner surface of the side plate 1. It is formed.
Further, a step portion 22 is formed at the lower part of the upper entrance edge 19b, which is smaller but deeper than the upper closing green 19b.
Note that a step portion 23 for indicating the lowest water level is provided below the lower closing edge 19a. A reinforcing member 24 is provided on the back side of such side plates 1 .

This reinforcing member 24 has a reinforcing plate 25 such as a plywood board arranged from the bottom surface of the tip of the coping 17 to the outer surface of the inner part 20 of the overflow groove 18, and also extends from the outer circumferential position of the inner part 20 of the overflow groove 18 to the outer surface of the inner part 20 of the overflow groove 18. Similarly, a reinforcing plate 26 such as a plywood board is disposed below the lower closing edge 19a, and these reinforcing plates 25,
26, the lower surface of the coping 17, and the outer surface of the side wall 3. R. It is coated and fixed with P.
The coping 17, the bottom wall portion 3, and the reinforcing plates 25 and 26 form a box shape with a space inside. Further, on the back side of the side plate 1, a plurality of reinforcing ribs 28 are formed vertically at predetermined intervals. In a pool made of such side plates 1 and bottom plate 2 made of silk, the inner surfaces of the corner portions are formed into curved surfaces, as shown in FIGS. 8 and below.

The side plates 1 at such corner portions are divided at a position half the bending angle 8 of the corner portion, and are butted against each other at these cut surfaces as shown in FIG. It is joined. By the way, although the overflow groove 18 is formed continuously in the corner portion, the overflow groove 18 in this portion is formed as follows.

That is, as shown in FIG. 10, the portion indicated by L is a portion where the inner surface of the side plate 1 extends linearly, and within the range of this straight portion L, the overflow groove 18
is formed with a cross-sectional shape as shown in FIG. 7, which matches the product die cutting direction as shown by the arrow direction in FIG. In the range L, they are continuous and have the same shape. In the part S, where the inner surface of the end continuous with the straight part L is curved, the cross-sectional shape along the die cutting direction has the same shape as shown in FIG. 7, and the opening of the opening 19 Over the range of the curve length of the lower end green 19a, that is, S,
They are formed so as to be sequentially shifted parallel to the die cutting direction along this curve. In the case of this embodiment, the trajectory of the center point P of the closed upper end green 19b shown in FIG. It has been moved to Therefore, in Figure 10,
The cross-sectional shape shown by x--x along the die cutting direction shown by the arrow matches the cross-sectional shape shown in FIG. (However, coping 1
(width of the overflow groove 18 varies) In addition, beyond the range S2 in which the cross-sectional shape is sequentially shifted along the inner curve, in a range T indicated by a substantially triangular shape, the outermost point of the deepest part of the overflow groove 18 That is, the locus of the point shown by m in FIG. 7 is formed in the shape of an arc whose radius is the line P-Q. However, the Q point is the end position of the range S2 of the curved part on the P-P line (shown in FIG. 10) of the locus of the center point P of the upper edge 19b of the opening shown in FIG. 7, and the end position of the layer S2 on the m line. This is the point where the line connecting them passes on the m line. In other words, it shows the boundary point of a point that bends in an arc shape from the parallel moved part. Further, the intersection point n between the groove side surface 21a of the overflow groove 18 and the horizontal tangent to the curved surface at the deepest portion is formed in a substantially straight line. Therefore, in the above-mentioned approximately triangular range T, as shown in FIG. 11, the middle garden 3 at the back of the overflow groove 18 is formed wider on the lower surface side than 12 in FIG. 7. . In the figure, 29 is a lifting step, 30 is a handrail, 31 is a skimmer, 32 is a circulation pump, 33 is a sand filter, 34 is a discharge pipe, 35 is a suction pipe, 3
6 is a hair catcher, 37 is a drain pipe, 38 is a drain port, 39 is a drain pipe, 40' is an overflow drain pipe, 41... is a resistor, 42... is a supporting member.

However, in the case of an assembled pool with such a structure,
A plurality of side panels 1... and a predetermined number of bottom panels 2 are pre-produced in a factory and completed by assembling them at the installation site, so the time required for construction is extremely short compared to a concrete pool. It's short.

The pool assembled as shown in Fig. 1 can not only be used by being buried in the ground, thereby adding pressure resistance to the ground, but also can be installed semi-embedded in the ground. Also, no matter the size of the pool, only one side plate
. . and the number of bottom plates 2 can be changed by appropriately selecting the number. However, in the joining structure of the side plates 1... and the bottom plate 2, the side walls 3 of the side plates 1... are butt-jointed to each other, so the assembly positions of the side plates 1... can be determined with high precision. Furthermore, since the bottom wall portion 4 and the bottom plate 2 are overlapped and bonded to each other, errors in the position of the bottom plate 2 can be easily absorbed by this overlapped bonding, and therefore, assembly can be easily performed.

In addition, since the bottom wall portion 4 of the side plate 1 and the bottom plate 2 have a core village 5a made of foamed urethane resin or the like in a sandwich structure, they have sufficient strength even when the user stands on them. It also has high water pressure resistance. Since such an assembled pool has an overflow groove 18 formed all around the inner circumferential surface, it has a good wave-dissipating effect and is sanitary because lacquer and saliva from swimming can be disposed of.

Moreover, since the overflow groove 18 is formed by opening its opening 19 into the inner circumferential surface of the pool and by slanting the inner part 20 outward and downward, a mold (not shown) that matches the inner surface of the side plate 1 is formed. ) in the direction of the arrow in Figure 7.
Yes, mold cutting can be done with a draft angle of zero. Therefore, the overflow groove 18 can be molded at the same time as the side plate 1, and can be formed integrally with the side plate 1, making manufacturing easy. Further, in the case of the above embodiment, the inclination angle 8 of the overflow register 18 is set to 45o, and with this angle, the angle Q of the lower closing edge 19a of the entrance part 19 does not become too small, and the strength is improved. Furthermore, the depth of the groove in the inner part 20 is also optimum, and the overflow water flowing in this groove 18 can be effectively guided. Further, the lower closing green 19a serves as a clue for a swimmer to grab from underwater, but if the angle of inclination 8 is 450 or more, it will not be possible to get a good hook. Furthermore, since the upper entrance edge 19b of the overflow groove 18 is recessed further than the lower closing edge 19a, the closing part 19
does not look too large from inside the pool, giving it a good appearance, and when the mold is pulled out, the upper opening green 19b separates from the mold faster than the lower closing edge 19a, so the pulling stroke of the mold is small. Corner,
Die cutting work becomes easier. Further, the formation of the step portion 22 at the lower part of the upper entrance edge 19b also facilitates the die-cutting operation for the same reason as above. On the other hand, a swimmer will ride on the copin 17 formed at the upper end of the side plate 1 having such an overflow groove 18 formed therein, and this load will be applied as a large bending load to each bent part of the overflow groove 18. However, on the back side of this side plate 1 there is a lip 28...
In addition, a reinforcing member 24 is particularly provided on the back side of the overflow groove 18, and since the reinforcing member 24 supports the load, the force applied to each bent part of the overflow groove 18 is reduced, preventing deformation. Prevent damage. Particularly in the case of this embodiment, the above-mentioned load first acts on one of the reinforcing plates 25, and the force of the bracket is transmitted through the other reinforcing plate 26 and acts on the bottom wall, so the other reinforcing plate 26 not only reinforces the coping 17, but also acts on the bottom wall. The protruding tip of the overflow register 18 can be firmly supported and mechanical strength can be effectively increased. Further, the reinforcing plates 25 and 26 can be made of inexpensive plate materials such as plywood, so they are not expensive. Furthermore, since such a reinforcing member 24 is attached when the side plate 1 is formed, the coping 1 extending horizontally outward is
This also prevents the hardening distortion of the coping 17, thereby maintaining the shape of the coping 17 with high precision. However, as shown in FIG. 10, the die-cutting direction of the pieces located at the corners of the side plates 1 is along the direction of the arrow, and in this case, the die-cutting direction is within the range of the straight line portion L. In addition, in the range of the curved part S2, the cross-sectional shape that matches the die cutting direction is shifted in parallel along the inner surface, so that the closing direction corresponds to the above die cutting direction.

Furthermore, since the end surface RR of the approximately triangular area forms an angle of, for example, 45 degrees with the die cutting direction, there are few obstacles to die cutting in this area. Therefore, even if the mold is pulled out in the direction of the arrow shown in FIGS. 7 and 10, the draft angle becomes zero, so the shape of the overflow groove 18 is not deformed by the mold, and on the contrary, In other words, since the shape is such that it does not interfere with the drawing out of the mold, even if the corner portion is formed into a curved surface, the overflow groove 18 can be molded integrally and simultaneously. In addition, since the groove width at the deep end of the overflow register 18' in the approximately triangular portion T is increased, the flow path area increases, and flow resistance generally increases at the bent portion of the flow path. However, in the above method, the flow path area is increased to make the flow smoother and overflow water can be removed reliably. In this case, in this portion T, the die cutting is performed at an angle of 45o with the divided end surface RR, so that the die cutting is possible even if the width of the groove is increased. As explained above, in the present invention, a side plate located at a corner portion whose inner surface is a curved surface is divided at an angle half the bending angle of the corner portion, and is butt-joined to each other. The overflow groove has a cross-sectional shape that continues linearly along the straight portion at least in the portion with a straight inner surface, and a cross-sectional shape that matches the cross-sectional shape of the straight portion in the portion with a curved inner surface. Since it is constructed by sequentially shifting parallel to the curve, the overflow groove provided in the curved surface part ends in the direction that coincides with the die cutting direction, so the gap removal slope during die cutting becomes almost zero. Smooth mold cutting is possible, and as a result, even if the side plate has a curved surface, the overflow groove can be molded integrally and simultaneously, and the cross-sectional shape of the overflow groove is almost the same and smoothly continues. It turns out.

This reduces the number of molding steps and improves production efficiency.
