Title:
SEMIDOUBLE AIR FILM STRUCTURE
Document Type and Number:
Japanese Patent JP3704671
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enhance rigidity and stability of a roof by doubling a film roof supported by a cable truss, arranging an air chamber independent of the interior of a house between them, and increasing pressure of the air chamber at strong wind time or the like.
SOLUTION: A cable truss is formed of upper and lower cables and a brace cable or the like, and this cable truss is stretched on a dome shape over compression rings 7 of an upper part of an outer wall 1. Next, an outer film 3a is fixed to an upper chord member of the cable truss, and an inner film 3b is fixed to a lower chord member, and an air chamber 8 independent of an indoor space 6 is arranged between them. At ordinary time, communicating holes 10 are opened, and the interior 6 of a house and the air chamber 8 are held in common in the same pressure condition, and at strong wind time and snowfall time or the like, the communicating holes 10 are cut off, and are made independent from each other, and only pressure of the air chamber 8 is increased, and rigidity and stability of a film roof 4 are improved. Therefore, control to adjust indoor pressure is simplified, and size reduction in an air blowing pressurizing device or the like is attained, and initial cost and running cost can be reduced.
