が高くつくことになる。[1. Background of the invention] Great for gymnasiums, music halls, leisure centers, etc. 6. For buildings that require internal space, large roofs with trussed steel frames are used. However, as the scale increases, construction requires a large number of very large lifting machines such as tower cranes, and work at high places is not efficient and can be dangerous. Therefore, equipment for safety measures is also important, and the overall construction cost will be high.

タワークレーン等が必要となる。In addition, methods have been adopted in which roof trusses are made into units and hoisted up to reduce work at heights, but if a temporary support stand is provided for each joint, the number of man-hours required for assembling and dismantling temporary equipment is reduced. Moreover, since the internal working space is limited, an external space for lifting the truss unit from the outside and a tower crane or the like with the corresponding lifting height and lifting capacity are required.
