本発明は、ガラス繊維強化プラスチツク製（以

などを構築する水槽の構築方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing an aquarium, such as an elevated aquarium, using a glass fiber reinforced plastic (hereinafter referred to as FRP) tank.

い。 For example, the method for constructing an elevated water tank is to assemble a formwork for a concrete tower on the roof of a building, go through processes such as concrete pouring, curing, and demolding, and then build a waterproof tank A1 and its protective mortar layer on the inside of the building. The method of applying A 2 to create water tank B (see Figure 1) has been widely used in the past, but the construction period is long because the waterproofing work must be carried out after the concrete has been cured and removed from the mold. Moreover, the waterproof layer a1 is easily affected by cracks in the concrete, making it difficult to maintain waterproof performance over many years. Furthermore, since the work is carried out at heights, it is not desirable from the viewpoint of safety management to have workers of different types involved in the waterproofing work.
このため、近年では、第２図に示すように、コ

FRPタンクｃ自体の防水性能が高いので、実際

クｃの周囲に所謂六面点検を行なうための空間
（これは作業者が入れるよう450mm以上の幅を必要
としている。）ｄを形成することが法的に義務づ
けられている。 For this reason, in recent years, factory-produced FRP has been installed inside concrete towers, as shown in Figure 2.
A method of installing a tank c to form an elevated water tank has come to be adopted. If you use this method,
Since the FRP tank c itself has high waterproof performance, there are almost no water leakage accidents in practice, but there is a space (450mm or more ) It is legally required to form d.
このため、タンク容積の割に搭屋が大きくなつ
て、コンクリート、鉄筋、仮設材等の使用量が増
加するばかりでなく、水圧に対する必要強度を
FRPタンクｃ自体が負担するので、FRPタンク
ｃとして厚肉のものが要求され、補強材の使用量
も多くなるのである。 For this reason, the tower becomes large in proportion to the tank volume, which not only increases the amount of concrete, reinforcing steel, temporary materials, etc. used, but also increases the necessary strength to withstand water pressure.
Since the FRP tank c itself bears the burden, a thick FRP tank c is required and a large amount of reinforcing material is used.
また、工期の面についても、搭屋のコンクリー
ト打設、養生、脱型等の後、FRPタンクｃを設
置するため、先の方法と大差がない。 In addition, in terms of construction period, there is no major difference from the previous method, as the FRP tank c is installed after concrete pouring, curing, demolding, etc. of the tower.

する点に特徴がある。 The present invention proposes a highly workable method for constructing a water tank that can eliminate these conventional drawbacks and also allow easy and quick installation of a formwork separator to an FRP tank. A metal object having a locking hole is fixed on the outer surface in advance, and a locking part that can be inserted and locked into the locking hole of the metal object is formed at one end of the separator, and the tank is installed at the aquarium construction site. After installing the separator on the outer surface of the tank, the separator is provided protrudingly in a state where the locking part is locked in the locking hole of the hardware, and the separator allows the tank and the outer surface assembled on the outside thereof to be The unique feature is that the water tank is constructed by pouring concrete while regulating the distance from the formwork.
以下、本発明の実施例を第３図以降の図面に基
づいて説明する。 Hereinafter, embodiments of the present invention will be described based on the drawings from FIG. 3 onwards.

空間である。 Figure 3 shows an elevated water tank constructed by the method of the present invention, in which 1 is a reinforced concrete tower which is an example of the frame, and 2 is also used as the inner formwork and waterproof layer.
The FRP tank 3 is a space that serves as a machine room for elevators, etc.
上記の高架水槽は次のようにして構築されたも

おく。 That is, as shown in FIGS. 4 and 5, a metal fitting 12 having a locking hole 11 consisting of a large diameter hole and a small diameter hole is provided on the outer surface of the side plate 2b of the FRP tank 2.
While the separator 4 is fixed in advance by a means such as the FRP lining 13, a flange-like locking member is provided at one end of the separator 4 and has a diameter smaller than the large-diameter hole portion of the locking hole 11 and larger than the small-diameter hole portion. A portion 4a is formed in advance.

端太である。 After the FRP tank 2 is delivered to the site and installed at the aquarium construction site, the separator 4 is attached to the FRP tank.
The locking portion 4a is attached to the outer surface of the tank 2 by the metal fitting 1.
FRP tank 2 is inserted into the locking hole 11 of 2 from the large diameter hole and protruded to be locked to the edge of the small diameter hole, and the separator 4 is used to fabricate a tower assembled on the outside of the FRP tank 2. The above-mentioned elevated water tank is constructed by pouring concrete 6 with the intervals between the outer forms 5 regulated and dismantling the outer forms 5 after the concrete 6 has hardened. 7 in FIG. 4 is a shaft made of steel pipe.

立てて構築されるものである。 The bottom plate 2a of the FRP tank 2 is formed to protrude laterally over a suitable length l (approximately 30 mm) than the side plates 2b. This serves to prevent the FRP tank 2 from floating during concrete placement. In addition, 8 in FIG. 3 is a manhole provided in the top plate portion 9 of the elevated water tank, and 10 is a mortar layer for waterproofing. The top plate portion 9 is constructed by assembling an inner formwork (not shown) in the same manner as in the conventional method shown in FIG.

ート６を打設する点に特徴がある。 FIG. 6 shows another embodiment, in which the outer surface of the FRP tank 2 is made of urethane foam, polystyrene foam, etc., which also serves as a heat insulating layer to prevent condensation and a layer to absorb the difference in expansion and contraction due to temperature changes between the concrete 6 and the FRP tank 2. The concrete 6 is characterized in that the concrete 6 is poured with the thin film 14 attached thereto.
尚、上記の実施例では、高架水槽を例にとつて
説明したが、本発明方法は受水槽にも適用可能で
ある。 In addition, although the above-mentioned embodiment was explained by taking an elevated water tank as an example, the method of the present invention is also applicable to a water receiving tank.
本発明は、上述した構成よりなるため、次の効

ータを取り付けることができる。 A metal object having a locking hole is fixed to the outer surface of the FRP tank in advance, and a locking part that can be inserted and locked into the locking hole of the metal object is formed at one end of the separator. After installation at the water tank construction site, the separator is protruded from the outer surface of the tank with the locking part locked in the locking hole of the metal fittings, so the FRP tank cannot be transported or brought to the site. The separator does not get in the way,
However, when protruding the separator on the outer surface of the FRP tank, it is easy and quick to install the separator by simply inserting and locking the locking part at one end of the separator into the locking hole of the metal fitting. A separator can be attached.

て済む。 Since the ready-made FRP tank will be used as both the inner formwork and the waterproof layer inside the tank, there is no need to assemble the inner formwork along the tank's inner surface shape or waterproof the tank's inner surface, reducing the construction period. Moreover, since the strength of the FRP tank and the surrounding concrete part resists water pressure, it is possible to make the FRP tank thinner and reduce the amount of reinforcing material. The concrete portion of the building is smaller, and the amount of concrete, reinforcing steel, temporary materials, etc. used can be reduced.
