A tank made of fiber reinforced resin having excellent corrosion resistance is used. The tank made of fiber reinforced resin is composed of an inner shell that directly contacts the liquid hazardous substance inside and an outer shell that covers the inner shell. Is provided with a gap for detecting the leakage of the fluid, and a leakage sensor is disposed therein. And since these tanks are buried underground and used, they can be thickened to withstand pressures such as earth pressure,
Reinforcing ribs are provided on the inner surface or outer surface of the tank. The reinforcing rib is preferably attached to the inner surface of the tank in order to prevent earth pressure from being applied to the connection between the rib and the tank body in the direction in which the rib is separated.

法及びそれに使用するリブ体を提供することにある。However, simply increasing the thickness of the tank as a means of reinforcing the tank increases the weight of the tank and impairs the light weight characteristic of resin. . Further, after the tank is formed, the reinforcing ribs are formed by overlaying a bar-shaped steel material such as a square bar on the inner surface of the tank with a hand lay of a fiber-reinforced resin to form a reinforcing rib. However, there is a problem in that the weight of the tank increases and the resinification of the entire tank impairs the intended image of the corrosion-resistant product. Further, in this method, since the elastic modulus of the material of the tank (fiber reinforced resin) and the elastic modulus of the rib are different, the external pressure is almost completely received by the rib, and in the worst case, the stress is distorted, and the tank is damaged due to stress concentration. There is a risk. Therefore, it is necessary to reinforce the part in order to allow it, and there is a problem that the cost is increased due to the labor and material cost. In addition, a ring-shaped rib with a part cut out in advance with fiber reinforced resin is molded,
A pair of metal turnbuckle-type fittings are provided at both ends of the tank, which are arranged on the inner surface of the tank.
In the method in which the reinforcing ribs are formed by connecting with a buckle-type connecting device and overlaying the reinforcing ribs with a hand lay of a fiber-reinforced resin, the formation of the reinforcing ribs is easy, but the purpose is to convert the entire tank into resin. There is a problem that the image of the product having corrosion resistance is impaired. The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to make it possible to make the entire tank resinous, and furthermore, it is easy to form the inner surface ribs and to reduce the manufacturing cost. It is an object of the present invention to provide a method for forming an inner surface rib in a fiber reinforced resin tank capable of suppressing an increase, and a rib body used therefor.

As shown in FIG. 5, the rubbing glass 13 is immersed in the resin tank 12 containing a resin obtained by adding a low-shrinkage agent or a filler to a tough thermosetting resin to impregnate the rubbing glass 13 with the resin. This is wound around a rib body forming die 16 between the rib body forming flanges 15 and 15 installed on the mandrel 14. Roving glass 13 impregnated with resin is
The resin is squeezed down through a bent bar (not shown) before being wound into the rib forming mold 16, and after being wound around the forming mold 16, the resin is scraped off with a rubber spatula or the like to make the glass fiber rich. By making the glass fiber rich and reducing the molding shrinkage, the occurrence of cracks during molding can be prevented. The resin is compounded by adding 15 parts of a low-shrinkage agent to 100 parts (parts by weight, the same applies hereinafter) of the iso-unsaturated polyester resin, or
To 10 parts of calcium carbonate. Also,
The bing glass used has 20 pieces with a count of 4500 g / km. Iso-unsaturated polyester resins have toughness, and low shrinkage can be achieved by adding a low-shrinkage agent or calcium carbonate to the resin. This makes it possible to reduce the molding shrinkage and prevent the occurrence of cracks during molding. Next, as shown in FIG. 2B, a film 17 is applied from above the roving glass wound in the mold 15 and then cured. Next, as shown in FIG. 3, after the thermosetting resin is cured, the rib-forming ribs 15 are removed from the mandrel 14, and the ring-shaped rib 1 is taken out. In the drawing, reference numeral 18 denotes a bolt for detaching the rib 15 for forming the rib body.
