<p>PURPOSE:To make it unnecessary to install a column and the like downward of an intersecting point of ridges and to secure a broad garret space by rigidly connecting beams constituting a ridge with each other at an intersecting point of ridges among bearing frames of a roof unit constituting a hipped roof. CONSTITUTION:In a roof unit B constituted of bearing frames 1, 2 and roof boards, a girder 14 and corner beams 16a, 16a, 16b, 16b of a ridge side roof unit B1 are rigidly connected. According to the constitution, bearing strength at an intersecting point 30 of a girder 10 and a down ridge 20 is secured without providing vertical members such as columns, trussed beams and others. Tie beams 13a, 13a, 13b, 13b and corner beams 16a, 16a, 16b, 16b of the ridge side roof unit B1 are rigidly connected, and tie beams 24a, 24a and corner beams 25a, 25b of an eaves side roof unit B2 are rigidly connected. According to the constitution, bearing strength at a connection 40 of the down ridge 20 is secured without providing the vertical members.</p> |
