BEAM REINFORCING MEMBER AND ROOF TRUSS STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a roof truss structure wherein a wide attic space can be provided with an easy construction, with less dangerous high-position operation for less labor and time, and a roof is supported more rigidly. SOLUTION: A roof truss structure 31 comprises four purlin beams 15 arranged in square frame to support a top part 2 of a roof 40 by its circumference. A connection beam 16 is provided which inclines in the tilt direction between top parts at four corners of the square-frame like purlin beam 15 and a roof surface 6 while connects to an outside wall 30. A beam reinforcing member 50 is bridged in the tilt direction of the roof surface 6 between the end part of main-house beam 15 of a bent beam 11 and the upper end part of outside wall 30.
