CONSTITUTION:Three roof panels 25 to 27 provided with three roof surfaces 33 to 35 are supported by a space support frame 28, forming a roof unit 15. This space support frame 28 is composed of installing two plane erection support frames 37 and 37 in space between two plane side support frames 36 and 36 opposedly set up with each other at both sides. With this constitution, bearing force against snow load and wind load or the like is built up, therefore it is able to be by far stable construction. In addition, it is favorably conformable to a roof part being composed of what plural roof surfaces are complicatedly connected such as a hip roof or the like.</p> |
