<p>PURPOSE:To make it possible to carry out roof truss work and roof surface installation work simply and safely for constructing a roof section of a building in a panel method. CONSTITUTION:A roof truss construction has a floor section 18 and four side walls 20, and a roof truss unit 12 is such that the upper ends of the side walls 20 form an angle of inclination corresponding to the pitch of a roof of the central part of a hipped roof and that it is installed on the upper part of an external wall 10 of a building by means of a beam 14. With the roof truss unit 12 as the center of roof truss construction, a roof panel is built between the upper end part of the side walls 20 mentioned above and the external wall 10 and is installed. According to the constitution, the roof is simply constructed. In addition, the roof truss unit 12 can be also formed at a plant in advance, so that roof truss work in a construction site is further simplified, and the floor section 18 can be used for a scaffold, so that it can be contributed to ensure safety for wok in a high place.</p> |
