PROBLEM TO BE SOLVED: To provide a portable fiber-reinforced plastic tank having excellent earthquake resistance, corrosion resistance, and maintainability which is easily assembled, disassembled, and moved. SOLUTION: The plastic tank includes a fiber-reinforced plastic-made container, and a frame which surrounds the container and holds the container. The frame includes a pillar PR1 for side surface in the vertical direction in contact with the outer surface of the container and arranged along the outer surface in order to suppress any outward deformation of the side surface of the container, a beam BM1 (BM2) for side surface for connecting the pillar for side surface so as to surround the container at least in the vicinity of the upper part and in a vicinity of the lower part of the container, outer posts (PR2, PR3) arranged along the outer periphery of the bottom surface to support the bottom surface of the container, an inner post PR4 arranged so as to surround a water discharge port, a beam BM5 for the inner periphery to connect the beam (BM2) for the outer periphery to connect the outer post and the inner post to each other, and connection beams (BM3, BM4) for the connecting the beam for outer periphery and the beam for the inner periphery to each other. At least the connection beams are in contact with the bottom surface of the container. COPYRIGHT: (C)2011,JPO&INPIT |
