<p><P>PROBLEM TO BE SOLVED: To develop a roof truss construction method for effectively using an attic space in a wooden house at a low cost with high workability. <P>SOLUTION: Roof truss members prepared on the ground are carried onto girders and beams, and installed on the girders according to marks such as dowels provided on the truss members and the girders and temporarily fastened and fixedly joined. Sandwich panel bodies serving as heat insulating materials are fixedly joined to the truss members in the manner of under-roof boards to construct a roof truss of the wooden house. Time and labor for heat insulating construction and eaves soffit decorative finishing can be omitted while forming a structure capable of withstanding load applied to a roof, with both the rigidity of the sandwich panel bodies and the structurally advantageous shape of the truss members. Further, the safety of workers can be improved by reducing processes of high lift work. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
