(Prior Art) Various assembled pools in which a plurality of plastic segments are connected to form an aquarium have been known, and several means for joining the segments are also known. Among these, as shown in FIG. 6, a groove 2 is formed along the joint edge 5 of each segment a,
The joint flanges 3, 3 are butted together with the rubber packing 11 interposed therebetween, and tightened with bolts 9 and nuts 8'. A sealing material 12 such as silicone sealant is poured and solidified along the butted upper edges, and then the adjacent There is a method in which the cover rail 10 is placed over the mating grooves 2, 2, and silicone sealant 12', 12' is further poured and solidified along both side edges.

(Problem that the invention aims to solve) However, although this conventional product has the advantage of being able to be bolted from above during assembly,
It connects two thin plates called joint flange plates, and there are two spaces called grooves, and the cover rail has to cover the two grooves, resulting in a large area and weak strength. . Furthermore, conventional products
Although it has a great sealing effect that prevents water, mud, dirt, etc. from flowing into the groove, the silicone sealant mentioned above has solidified, so it cannot be disassembled after assembly, disassembled and stored, which is the main purpose of this type of pool.

A large number of holes 7, 7' are bored through the shaft of the bolt 9, and a bolt shaft receiving hole 7'' is formed at the rear of each nut 8'. The cover rail 10 is made of FRP and has a tape-like waterproof sealing material 19 coated with adhesive only on one side, and further covers the groove 2 and the upper edge of the waterproof sealing material 19. A downward fitting flange plate 20 is integrally formed in the middle of the lower surface, and a downwardly widening fitting flange plate 21 is integrally formed at one end.
The length of the cover rail 10 in the longitudinal direction is formed to be 1/2 the length of the joint edge 5 (as shown in the first figure). , one pair each. In addition, in the figure, 22 is a washer, 23 is foamed urethane as a reinforcing filler, 23' is a reinforcing beam material, 24, 25
26 is a sanitary segment incorporating a shower, a foot washing area, etc., and a watertight plug and a drain hole drilled into the horizontal bottom wall 13.

Next, the method of assembling the embodiment of this invention will be described. First, one side of the waterproof sealing material 19 is adhered over the entire length of the outward facing surface of the thick wall 6, that is, the joint edge 5', and the adjacent segments are joined. The collar plate 3 is brought into contact with the other surface of the waterproof sealing material 19. After drilling a hole in the waterproof sealing material 19 with a drill at the position where the bolt 9 will pass, pass the shaft of the bolt 9 through each hole 4, 7, 7' via a washer 22, and then into the screw hole 8 of the nut 8'. Tighten.
At this time, since the nut 8' is fixed within the thick wall 6, only the bolt 9 is screwed. After that, one pair of cover rails 10, 1
0 facing each other, and are fitted into the groove 2 by 1/2 of the total length, and the fitting flange plates 21, 20 are locked to each protrusion 15 and bolt head 9'. Connect other segments in the same way.

Next, to explain the usage condition of the embodiment of this invention, when the water tank 1 is filled with water and is in use, pressure is applied to the cover rail 10 from above, so that each protrusion 15 and the bolt head are Each fitting collar plate 21, 20 is securely locked to 9', and the cover rails 10, 10 extend over the entire length of the joint edge, and the cover rail 10 is made of plastic and the fitting collar plate 2
1 has a diverging shape, so when it is fitted into the concave groove 2, its elasticity pushes the groove wall 2' and presses the fitting flange plate 20 against the joining flange plate 3, fixing it and preventing it from coming off. In addition, to drain the water in tank 1,
Normally, this is done by removing the watertight plug 25 from the drainage hole 24 drilled into the bottom wall 13 itself. However, in this embodiment, since the joint portion of the cover rail 10 is not completely sealed, a small amount of water, mud, dirt, etc. may flow into the groove 2. At this time, the cover rail 10 is removed, the watertight plug 17 is removed, and the water is discharged from the discharge hole 16.

(Effect of the invention) In this way, this invention forms the horizontal edge of each horizontal bottom wall and the inverted U-shaped edge of the circumferential wall that is continuous with this horizontal edge as a joint edge, and connects the intermediate segment. A concave groove is integrally formed over the entire length of one joining edge of the right end segment and the joining edge of the right end segment, and the other joining edge of the middle segment and the joining edge of the left end segment are integrally formed. Since a thick wall is formed over the entire length of the groove, by connecting this groove and the thick wall, there is only one groove at each connection part, and therefore the width of the cover rail that shields the groove is The width of the conventional product is only half that of the conventional product, and the width of the cover rail, which is particularly weak in strength, is halved, and the other half has a thick wall that is strong, so the overall structure is extremely strong and robust, and the thickness is also reduced. Since the steel plate is buried within the wall along its entire length, its strength is increased.

This design also eliminates the need to harden both side edges of the cover rail and the upper edge of the rubber seal with a sealant such as silicone sealant, and integrally forms a downward fitting flange plate midway through the lower surface of the cover rail and at one end, making it easy to fit. By attaching and detaching the flange plate to the groove, assembly, disassembly, disassembly and storage, and reassembly can be carried out extremely easily.

Furthermore, since this invention does not seal the cover rail as in the conventional case, it is not possible to achieve perfect watertightness between the cover rail and the segment. By using this cover rail, the fitting collar plate formed on the cover rail is formed at such a height that its lower edge engages with the head of the bolt and the protrusion protruding from the groove wall. The cover rails are closed, and even if a swimmer stands on the cover rail, they will not tilt or fall and create a gap, and they will fit together stably, and the cover rail is made of plastic.
Since one of the fitting flange plates is formed in a widening shape, it has an elastic effect, and since it spans the entire length of the joint edge, it has a considerable watertight effect, preventing water, mud, dirt, etc. from entering the groove. is small.

In particular, the joint flange plate that forms the groove is tightened with bolts and nuts through a waterproof sealing material, and a watertight plug is fitted into the discharge hole provided in the bottom plate of the groove, so it is very convenient for swimming pools. There is no water leakage outside, and the water resistance is sufficient, and water, mud, dirt, etc. that have entered the groove can be drained out by removing the watertight plug as necessary, keeping the inside of the pool sanitary. It is something that can be done. In other words, if the cover rail itself is completely sealed, the workability of assembly and disassembly will be poor, so even if it is not completely sealed, the cover rail can be installed fairly reliably, and the workability of assembly and disassembly is improved. A small amount of leaked water is stored in a groove to prevent water from leaking out of the pool, and can also be drained if necessary. In addition, since adhesive is applied to one side of the waterproof sealing material interposed between the joint flange plate and the thick wall, the waterproof sealing material will be stuck to the thick wall, so it will not shift when inserting the bolt. Without,
Bolts can be inserted quickly, connections can be made reliably, and work efficiency is high.

Furthermore, since the connecting nuts are fixed to the iron plate buried in the thick wall, it is sufficient to thread the bolts from above, and the strength is reduced by making both the connecting parts grooved like in the conventional example. The thick wall increases the strength and allows easy work from above.
