The unit panel is connected to the upper, lower, left and right by connecting bolts and nuts to each fastening hole of the connecting frame in a state in which the connecting frame of the unit panel formed by the above process is in close contact with each other. After forming and fixing by connecting the reinforcement angle to the unit panels corresponding to each other to withstand the load of the fresh water in the tank, and then the epoxy-based paint liquid or powder coating to prevent the rust of the tank.

However, in the conventional stainless unit panel configured as described above, when the stainless plate is pressed to form an embossing and connecting frame, the bending angle and length of the connecting frame do not match exactly according to the position where the stainless plate is placed on the press. There was a problem of falling precision.

In addition, as shown in Figure 1a, the gasket (G) is inserted between the unit panels (10, 10 ') by fastening the bolt / nut to the fastening hole of the connection frame 11 which is in contact with each other surface. The gap generated between the connection frame 11 and the unit panel 10, 10 'is bent to the outside at the center of the bolt / nut which fixes the unit panels 10 and 10' by the high internal pressure of the tank. There was a problem of water leakage, and the high internal pressure of the water tank is concentrated along the inner surface of the embossing, so that the embossing is deformed and the water tank is severely deformed because the outer surface of the embossing that the shear stress corresponding to the internal pressure acts is tensioned. There was a problem that is broken.

In addition, a separate inner and outer reinforcing brackets 20 and 21 are mounted to support the unit panels 1 and 1 'where the bolts and nuts are fastened to the fastening holes as the connecting frames 11 are in close contact with each other.

Formed and fixed by connecting the reinforcement angle by mounting the inner and outer reinforcement bracket of the stainless unit panel can not directly connect the reinforcement angle to the mutually corresponding unit panels to withstand the load of the fresh water in the tank.

However, the SMC tank constructed as described above is formed by joining glass fibers in order to increase the strength of the thermosetting resin. Therefore, the nonwoven fabric of the glass fiber is thin and the tensile strength of the thermosetting resin is 1/7 of iron, 1/9 of stainless steel, Although it is weak about 1/4 of aluminum, it is suitable for small-capacity tanks.However, in medium and large tanks, the unit panel does not withstand the strength, causing cracks. There was a problem that has been harmful to the human body.

In addition, when the frame is connected closely to each other, bolts / nuts are fastened to the fastening holes to support the fixed unit panel, and when the inner and outer reinforcement brackets are mounted on the stainless unit panel, The same problem was involved.
