摘要

PPROBLEM TO BE SOLVED: To provide a pipe greenhouse with a ventilation window serving as both of reinforcement and a lining foundation. PSOLUTION: The pipe greenhouse with a ventilation window comprises dual structured arch pipes. Outer arch pipes and inner arch pipes are also thrusted into a foundation to which two pipes are firmly fixed and which is laid under the ground, and fixed using metal fittings. The right and left outer arch pipes are joined to each other at their upper parts. The inner arch pipes cross each other, the crossover parts are each fixed using metal fittings, and the right and left tip parts are fixed to the positions lower than the joining parts of the opposite outer arch pipes at regular intervals. The right and left lower parts of the curved parts of the outer and inner arch pipes are fixed to each other using metal fittings. The outer arch pipes are joined so as to fix the tip part of one side pipe to the lower part of the opposite pipe at the regular interval from the tip part of the opposite pipe. A ventilation window frame is mounted at the tip part of the outer arch pipe. PCOPYRIGHT: (C)2004,JPO
