PROBLEM TO BE SOLVED: To dispense with a large-scaled temporary erection to enable construction while using a building to a certain extent, and to keep the external appearance after construction without impairing it. SOLUTION: A reinforcing frame structure 30 transmitting a load to an existing column 20 is installed above an existing attic beam 1. Next, a hoisting means 35 having a load weightometer 36 is installed between the reinforcing frame structure 30 and the attic beam 1. A hanging means 38 is installed between the reinforcing frame structure 30 and the attic beam 1. The attic beam 1 is lifted up by the hoisting means 35. The hoisting load is measured by the weightometer 36. A hoisting force by the hanging means 38 is adjusted so as to be similar to the hoisting load by the hoisting means 35. Next, the hoisting means 35 is removed. Thereby, a large scale temporary installation for the chief wooden construction is unnecessitated and the structure can be constructed while using in an extent and further, it is sufficiently reinforced without damage of the appearance, only by adding the reinforcing frame structure 30 and the hanging means 38 to the roof frame after construction.
