Description

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

This is an assembled swimming pool in which the side plates and bottom plates made of F-R-P (reinforced plastic) are pre-produced in a factory, and the required number of side plates and bottom plates are assembled in succession at the installation site. Conventionally, pools were thought of as small or simple pools, so they did not have structures such as overflow grooves.

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 for this reason it is necessary to provide an overflow groove. Additionally, as the depth of the pool increases, steps for lifting and lowering the pool are also required. Since the side plates of the assembled pool are integrally molded using F-R-P, it is desirable that the overflow groove and steps are also formed by simultaneous molding.

In this case, if it is attempted to form the overflow groove and the step separately from each other, there is not enough space for molding, and molding is difficult. In other words, the overflow groove is generally
They are formed near the water surface because they serve functions such as allowing swimmers to throw away phlegm and saliva, guiding waves generated by swimming to prevent reflected waves, and flushing out floating objects on the water surface. Ru. On the other hand, in the case of lifting steps, steps below the water surface are difficult to visually recognize from above the water surface. In addition, if steps are provided above the water surface and far from the water surface, it will give a sense of fear to swimmers trying to enter the pool, and to swimmers trying to get out of the pool, the buoyant force will act from within the pool. Difficult to rise outside the pool. Therefore, it is desirable to provide one step above the water surface but close to the water surface. However, if the overflow groove and the step are both formed separately on the water surface and close to the water surface, there is no molding space, so one or the other will be sacrificed. This invention was made based on these circumstances, and its purpose is to
When forming the step and overflow groove integrally on the side plate made of reinforced plastic such as, by forming the top step to match the lower edge of the opening of the overflow groove, space can be used effectively and the overflow It is an object of the present invention to provide an assembled pool with an overflow groove that is easy to use with both grooves and steps.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Figure 1 shows the state of the assembled swimming pool upon completion of assembly.
As shown in Figure 2, this pool consists of multiple side plates 1 and 1.
. . . and the required number of at least one bottom plate 2 are assembled by joining them together at their adjacent edges. Each side plate 1 above...
. . . includes a side wall portion 3 formed of F-R-P (reinforced plastic) and a core material 5a such as foamed urethane resin extending horizontally from the lower edge of the side wall portion 3 to the body. It has a bottom wall portion 4 covered with F-R-P5b. In addition, in the case of the bottom plate 2, the bottom wall portion 4 of the side plate 1
Similarly, the core material 5a such as foamed urethane resin is
It is coated with P5b. As shown in FIG. 3, a butt joint flange 6 is integrally formed on the edge of the side wall 3 of the side plate 1, and a lap joint flange 6 is formed on the periphery of the bottom wall 4. 7a and 7b are formed. The lap joint flange of the bottom wall portion 4 is located between the adjacent side plates 1 and 1 at one flange portion 7.
As shown in FIG. 6, the flange portion 7a is located on the lower side, and the other flange portion 7b is located on the upper side, so that they can overlap each other vertically. Further, on the periphery of the bottom plate 2, there are provided lower portions of each of the bottom wall portions 4 of the side plate 1 for overlapping and joining. Flange portions 8a and 8b (only one is shown) are formed to be overlapped and joined to the upper flange portions 7a and 7b. Then, as shown in FIG. 5, the adjacent side plates 1, 1 are abutted together after sandwiching a backing 9 of J, such as a sponge, between the butt joint flanges 6, 6, and bolts 10...・・・・・・
and nuts 11... are connected and fixed to each other. Note that 12... are washers, and 13 is putty. In addition, between the bottom wall parts 4 and 4 of the side plates 1 and 1, as shown in FIG.
The upper flange portions 7b for overlapping and joining are overlapped on top of each other, and these are joined and fixed to each other with blind rivets 14.

Note that 15 is a covering material made of F-R-P, and 16 is a gel coat paste coated on this covering material 15. Furthermore, the bottom wall portion 4 of the bottom plate 2 and each side plate 1...
. . . are interconnected in the same manner as the structure shown in FIG. 6 above. In such an assembled pool, a flange-shaped deck 17 extending outward horizontally is integrally formed at the upper end of each side plate 1.
When the side plates 1 are assembled as shown in FIG. 1, these decks 17 are continuous all around the opening edge of the pool.

Further, an overflow groove 18 is formed at a position below the deck 17.

This overflow groove 18 is formed integrally with each side plate 1, so that when these side plates 1,... are connected to each other, it is constructed continuously over the entire circumference of the inner surface of the pool. It's getting old. And this overflow groove 18
is formed as shown in detail in FIG. In other words,
The overflow groove 18 has an opening 19 on the inner surface of the side plate 1.
The inner part 20 thereof is inclined outwardly and downwardly. Then, the groove side surfaces 21a and 21b are adjusted so that the opening end 11 of the opening 19 and the groove width 12 of the inner part 20 are the same.
are formed parallel to each other. Further, the overflow groove 18 of this embodiment is configured such that the above-mentioned inclination angle 0 is at an angle of 45 with respect to the vertical line H--H. Furthermore, the lower opening edge 19a of the opening 19 of the overflow groove 18 is slightly protruded inward compared to the upper opening edge 19b.
In other words, the upper opening edge 19b is formed deeper than the inside of the side plate 1. Further, at the lower part of the upper opening edge 19b, there is a stepped portion 2 which is small but recessed than the upper opening edge 19b.
2 is formed. Note that a step portion 23 for indicating the lowest water level is provided below the lower opening edge 19a. A reinforcing member 24 is provided on the back side of such side plates 1.

This reinforcing member 24 extends from the bottom surface of the tip of the deck 17 to the outer surface of the inner part 20 of the overflow groove 18, and a reinforcing plate 25 such as a plywood board is disposed thereon. Similarly, a reinforcing plate 26 such as a plywood board is disposed below the lower opening edge 19a, and these reinforcing plates 25,
26, the lower surface of the deck 17, and the side wall portion 3
The outer surface is covered and fixed with F.R.P 27, and formed into a box shape with a space inside by the deck 17, side wall portion 3, and reinforcing plates 25 and 26. Further, on the back side of the side plate 1, a plurality of reinforcing ribs 28 are formed vertically with a predetermined gap therebetween. The side plate 1 located near the corner of the pool in such a side plate 1... has a step 2 for lifting and lowering.
9a, 29b, 29c and 29d are provided.

These steps 29a, 29b, 29c, and 29d are the eighth step.
As shown in the figure, they are integrally formed with the side plate 1 and are formed so as not to protrude further inward from the inner surface of the pool, and each upper surface is formed into an uneven surface for anti-slip purposes. Step 2 located at the top
9a, the opening 1 of the overflow groove 18
It is continuously molded integrally with the lower opening edge 19a so as to be flush with the upper surface of the lower opening edge 19a at 9.

In other words, the uppermost step 29a is formed into a planar shape by horizontally extending the upper surface of the lower opening edge 19a of the overflow groove 18 at this position. Therefore, as shown in FIG. 9, the overflow groove 18 at this position is formed to bypass the outer periphery of this step 29a, and the upper opening edge 19b and deck 17 located above this position are This step 2
It escapes outward in response to 9a. A pair of left and right handrails 30, 30 are attached above the step 29a.

These handrails 30, 30 are made of pipe material bent as shown in FIG. . In this case, fixing grooves 31 into which the ends of the handrails 30, 30 are inserted are integrally formed on both sides of the uppermost step 29a, and the fixing grooves 31 are open on the sides and the overflow groove 18 is inclined. It has an inclination angle that matches. And the mounting hole 3 is on the wall of the fixing groove 31.
2 is formed, and a stator 34 having a nut 33 molded therein is inserted and fixed into this mounting hole 32. Therefore, after the end of the handrail 30 is inserted into the fixing groove 31, a bolt 35 is passed through it, and this bolt 35 is inserted into the stator 3.
One end of this handrail is fixed by screwing it into the nut 33 of No.4. Note that the insertion direction of the bolt 35 is not limited to inserting from above as shown in FIG. 10, but if the bolt 35 is inserted inward from both left and right sides as shown in FIG. Since a large space is secured in this direction, work efficiency is good. Further, a through hole 37 is formed in the deck 17 opposite to such a fixing groove 31, and a fixing pipe 38 extending from the lower surface of the deck 17 to the wall of the overflow J groove 18 is attached to the lower part of the through hole 37. There is. A mounting hole 39 is provided at the outer edge of the deck 17, and a stator 41 having a nut 40 molded therein is mounted in the mounting hole 39. This stator 41
An insertion hole is provided in the wall of the fixed tube 38 opposite to the through hole, and a locking hole is formed at the other end of the handrail 30 opposite to this insertion hole. Therefore, the bolt 42 is inserted through the mounting hole 39 of the deck 17 and screwed into the nut 40, and its tip is inserted into the through hole of the stator 41 and the fixed wall 38.
The other end of the handrail 30 is also fixed by passing through the insertion hole and inserting it into the locking hole of the handrail 30. The other end surface of the handrail 30 is cut at an angle so as to be in line contact with the outer wall of the overflow groove 18. In addition, 43 in the figure
is a skimmer, 44 is a circulation pump, 45 is a sand filter, 46 is a discharge vibe, 47 is a suction vibe, 48 is a hair filter, 49 is a discharge vibe, 50 is a drain port, 51
is a drainage vibe, 52 is an overflow drainage vibe, 53
is a stake, and 54 is a support member.

However, in the case of an assembled pool with such a configuration, a plurality of side plates 1... and a predetermined number of bottom plates 2 are produced in advance at a factory, and these are assembled at the installation site to complete the pool. Therefore, the time required for construction is extremely short.

The pool assembled as shown in Fig. 1 can not only be used by being buried in the ground and have pressure resistance added to the ground, but also can be installed semi-embedded in the ground. Also, regardless of the size of the pool, the side plate 1.
It can be changed by appropriately selecting the number of . . . and the number of bottom plates 2. However, side plate 1... and bottom plate 2
In the case of the joint structure with the side plates 1..., the side wall portions 3 of the side plates 1...
The mutual assembly positions can be ensured with high precision, and since the bottom wall portion 4 and the bottom plate 2 have parts that are overlapped and joined to each other, it is easy to absorb errors in the position of the bottom plate 2, and therefore, it is easy to assemble. I can do it.

In addition, since the bottom wall portion 4 of the side plate 1 and the bottom plate 2 are constructed with a core material 5a such as foamed urethane resin in a sandwich structure, they have sufficient strength even when the user stands on them. It also has high water pressure resistance. In addition, this assembled pool has an overflow groove 18 on the inner circumferential surface near the water surface.
The groove has a good wave-dissipating effect, allows for easy disposal of phlegm and saliva during swimming, is hygienic, and is easy to use as an overflow groove.

Since the overflow groove 18 is continuous over the entire circumference of the inner circumferential surface of the pool, waves generated by swimming flow into the overflow groove 18 no matter which direction they travel.
Since there is no possibility of waves hitting the wall and being reflected, the wave dissipation effect is extremely good, and the overflow groove 18
The water and foreign matter that have flowed into the tank can be efficiently purified or eliminated by guiding them to the skimmer 43 at one location. 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. can be pulled out in the direction of the arrow in Figure 7. 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 θ of the overflow groove 18 is set to 45°, and if this angle is set, the lower opening edge of the opening 19
The angle α of 9a does not become too small, which is advantageous in terms of strength, and the groove depth of the inner part 20 is also optimal, so that this groove 18
The overflow water flowing inside can be effectively guided. The lower opening edge 19a also serves as a grip when a swimmer is grabbed from underwater, but if the angle of inclination θ is 45 or more, it is difficult to get a grip. Furthermore, since the upper opening edge 19b of the overflow groove 18 is recessed deeper than the lower opening edge 19a, the opening 19 does not look large from inside the pool, giving a good appearance, and when removing the mold, the upper opening edge 19b Since it leaves the mold earlier than the lower opening edge 19a, the drawing stroke of the mold can be shortened, and the mold cutting operation becomes easier. Further, forming the step portion 22 at the lower part of the upper opening edge 19b also facilitates the die-cutting operation for the same reason as above. On the other hand, a swimmer will ride on the deck 17 formed at the upper edge of the side plate 1 with 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, not only are ribs 28... formed on the back side of this side plate 1, but also a reinforcing member 24 is provided especially on the back side of the overflow groove 18, and this reinforcing member 24 helps to absorb the load. Because of the support, the force applied to each bent portion of the overflow groove 18 is reduced, thereby preventing deformation and damage.

In particular, in the case of this embodiment, the above load is applied to one of the reinforcing plates 2
5 and this force is transmitted through the other reinforcing plate 26 and acting on the side wall portion, so the other reinforcing plate 26 not only reinforces the deck 17 but also firmly supports the protruding tip of the overflow groove 18 to provide mechanical strength. It can be effectively improved. Further, the reinforcing plates 25 and 26 can be made of inexpensive plate materials such as plywood, so they are not expensive. Furthermore, since the reinforcing member 24 is attached when the side plate 1 is formed, it prevents the deck 17 from extending outward in the horizontal direction from hardening distortion, thereby maintaining the shape of the deck 17 with high precision. It will be done.

On the other hand, lifting steps 29a, 29b, 29c, 29d
Since it is formed integrally with the side plate 1, it is easy to manufacture and assemble, and since it does not protrude inward of the pool, it does not interfere with swimming. Moreover, since the uppermost step 29a is formed to match the lower opening edge 19a of the overflow groove 18, it is easy to use. Since the lower opening edge 19a of the overflow groove 18 is very close to the water surface, providing the step 29a here will help swimmers coming up from the water.
Swimmers can climb up by reducing the force required to get out of the water, where they feel the extreme weight of their bodies from underwater where buoyancy acts, and swimmers who descend by steps feel a sense of fear because they are so close to the surface of the water. Not at all. Also, overflow groove 1
If the lower opening edge 19a of 8 is used as the step 29a, there is no need to specially form another step at another location close to the water surface, and therefore there is no need to secure a space for this special step. . Moreover, overflow groove 18
If the step 29a is formed on the lower opening edge 19a, integral molding is possible, which facilitates molding. Furthermore, since the fixing groove 31 of the handrail 30 is made to coincide with the inclination direction of the overflow groove 18, the molding direction becomes the same, and the fixing groove 31 can be integrally molded.

Since the handrail 30 is fitted into such a fixing groove 31, the positioning of the handrail 30 is ensured, and the weight of the swimmer can be reliably received by the fixing groove 31 via the handrail 30. It is strong. As explained above, this invention is integrally molded with each side plate made of reinforced plastic such as F-R-P, and when these side plates are joined, it is continuous over the entire circumference of the inner circumferential surface of the pool, and the inner surface of each side plate is integrally molded. Since we have formed an overflow groove that has an opening at the bottom and whose inner part slopes downward toward the outside of the pool, the reoverflow groove is formed all around the inner circumference of the pool, which prevents waves generated by swimming from occurring. Even if the swimmer moves in the direction of the swimmer, it will flow into the overflow groove and will not hit the wall and be reflected, so it has a good wave-dissipating effect, and sputum and saliva from swimming can be disposed of into the overflow groove close to the swimmer. The treatment is easy and sanitary, and the water that has flowed into the overflow groove can be guided to one place and purified or removed efficiently.

Moreover, since multiple steps are integrally formed on at least one side plate without protruding into the pool,
The steps do not protrude into the pool and do not interfere with swimming, and the top step is aligned with the lower edge of the opening of the overflow groove, so there is no need for special space for the top step, and the top step does not interfere with swimming. Since the step can be molded integrally with the lower edge of the opening of the overflow groove, molding is facilitated. Furthermore, since the overflow groove is provided at a position close to the water surface, and the uppermost step is formed at the lower edge of the opening of such overflow groove, the uppermost step is located close to the water surface, and therefore, it is difficult for swimmers to ascend and descend. It also has the effect of making it easier to use and easier to use.
