CONSTRUCTION METHOD FOR ROOF TRUSS

摘要

PROBLEM TO BE SOLVED: To provide a construction method for a roof truss capable of reducing greatly dangerous work at an elevated place and reducing the time and labor required for the construction by performing assembly work of the roof truss on an inner side more than an external wall line of a building exclusively when the building is constructed at a lot in an area where buildings stand close together. SOLUTION: The roof truss 1 installed above the uppermost story of a building A is assembled on a floor surface 3 of the uppermost story in the direction in which its angle is deviated to any of right and left sides for the mounting direction for the building A so that it is stored on the floor surface 3 of the uppermost story and it can be directly attached to a support member 2 supporting the roof truss 1, is lifted upward and vertically up to a mounting height to the support member 2 while keeping its direction, and is rotated up to the mounting direction to the support member 2 to attach it to the support member 2.
