<p>PURPOSE:To secure such a roof truss that is able to firmly hold a roof panel by connecting a column setting part for a body beam of a house body part to an attached beam of a house annex part with a joint beam, and supporting the roof panel with a pier member erected on this joint beam and a trussed girder set up between a mounting bracket installed in a column and a body beam. CONSTITUTION:This is a roof truss 1 which adjoins a house body part A and forms a house annex part B lower in story than the house body part A. A setting part of a column 4 of a body beam 12 set up in the house body part A and erecting this column 4 is connected to an attached beam 30 of the house annex part B in parallel with this body beam 12 with a joint beam 2. Then, a pier member 3 is erected in the joint beam 2, installing a mounting bracket 5 in the column 4, and further a trussed girder 6 parallel with the joint beam 2 is set up between the body beam 12 and the attached beam 30, and a roof panel P1 is supported by the pier member 3, the mounting bracket 5 and the trussed girder 6. With this constitution, each column 4 of the joint beam 2 and the house body part A is effectively utilized and thereby the roof panel P1 is firmly supportable.</p> |
