PURPOSE: To form a high rigidity vertical piping unit from a small quantity of reinforcements by coupling together vertical piping unit bodies arranged in a plurality of layers using vertical members, and furnishing between them a truss-form reinforcement which couples the upper layer pipe with the lower layer pipe.
CONSTITUTION: Vertical piping unit bodies 4 in a plurality of layers are arranged in rows where a plurality of pipes 2 are installed on a plurality of transverse members 1 in raft form, and these vertical piping unit bodies 4 in layers are coupled together by longitudinal members 5. One vertical piping unit 7 consists of vertical piping unit bodies 4 in two layers, and the upper layer pipe and lower layer pipe 2 are coupled together by a truss-form reinforcement 6 so that the side face of the unit 7 is prevented from deformation, The whole unit structure is thereby made rigid to prevent the unit from deflecting, and lifting and hang-down of the unit can be done smoothly.
