DRAINING FACILITY DESIGN TABLE

摘要

PPROBLEM TO BE SOLVED: To provide a draining facility design table which facilitates the determination of a type of a drain pipe joint in a draining facility and the determination of the diameter size of a drain down pipe etc. PSOLUTION: The draining facility design table is provided for determining the type of the drain pipe joint, the diameter size of the drain down pipe, and the diameter size of a drain horizontal main pipe, and has: an entry column for each appliance per floor; entry columns for a steady flow rate q of each appliance per floor, a total steady flow rate obtained by summing up the steady flow rates q, and an appliance mean drainage flow rate qd of an appliance representative of the floor; an entry column for a pipe steady flow rate Q that is a steady flow rate of the drain down pipe; an entry column for a load flow rate QL of the drain down pipe determined by a drain down pipe selecting diagram based on the pipe steady flow rate Q and the appliance mean drainage flow rate qd; an entry column for a determined load flow rate QY of the drain horizontal main pipe corresponding to each story of an apartment house; an entry column for the type of the drain pipe joint and the diameter size of the drain down pipe based on the load flow rate QL of the drain down pipe; and an entry column for the diameter size of the drain horizontal main pipe based on the load flow rate QY of the drain horizontal main pipe.
