Assemblable aquaboard made of fiber-reinforced plastic (FRP)

An assembleable aquaboard made of fiber-reinforced plastic (FRP), comprising,

• a first plate comprising a first T-shaped slot on the top surface and a second T-shaped slot on the right-side surface, where the first plate is rectangular;
• a second plate comprising a third T-shaped slot on the top surface and a fourth T-shaped slot on the left-side surface, wherein the second plate is rectangular;
• a third plate disposed on the front side of the first plate and comprising a fifth T-shaped slot on the top surface and a sixth T-shaped slot on the right-side surface, wherein the third plate has an arc-shaped surface on the left side of the third plate;
• a fourth plate disposed on the front side of the second plate and comprising a seventh T-shaped slot on the top surface and an eighth T-shaped slot on the left side surface, wherein the fourth plate has an arc-shaped surface on the right side of the fourth plate;
• a first T-shaped connector disposed in the first T-shaped slot and the fifth T-shaped slot to connect the first plate and the third plate;
• a second T-shaped connector disposed in the third T-shaped slot and the seventh T-shaped slot to connect the second plate and the fourth plate;
• and
• a first I-beam connector disposed in the second T-shaped slot, the fourth T-shaped slot, the sixth T-shaped slot and the eighth T-shaped slot to connect the first plate, the second, the third plate and the fourth plate to form the assembleable aquaboard,
• wherein the first plate, the second plate, the third plate, the fourth plate, the first T-shaped connector, the second T-shaped connector and the first I-beam connector are made of FRP and each of the first plate, the second plate, the third plate and the fourth plate has the same or substantially the same thickness.
