Solar module installed roof renewal method using portable roll forming machine and roof renewal structure by the method

摘要

The present invention relates to a photovoltaic module installation roof renewal method using a portable roll forming machine, and a roof renewal structure obtained thereby, the method and structure allowing no concern for water leaks, excellent structural safety, a simple construction, and a reduced construction period. According to the present invention, provided are a photovoltaic module installation roof renewal method using a portable roll forming machine, and a roof renewal structure, and the roof renewal method for installing a photovoltaic module on the roof of a building constructed with a roof frame (1) having a repetitively formed crest (2) and root (3) includes the steps of: interposing an insulator (4) at the root (3) of the roof frame (1); producing a photovoltaic module installation roof panel (100) in a length corresponding to the length of the roof at a roof renewal site by using a portable roll foaming machine (10), so as to transport the photovoltaic module installation roof panel (100) onto the roof; installing the photovoltaic module installation roof panel (100) on the roof frame (1) at which the insulator (40) is interposed; fastening a bracket (40) for installing a photovoltaic module (30) on the photovoltaic module installation roof panel (100); and installing the photovoltaic module (30) on the bracket (40).
