PURPOSE: A stone corbel support device for a building is provided to facilitate to bore an insulation material by rotating a saw blade part and to stably support stone corbels by widely being in contact with the stone corbels through a plane contact part. CONSTITUTION: A stone corbel support device for a building comprises a supporter(101), a saw blade part(106), and a saw blade part detaching unit. The supporter is formed with an inner screw part(103) in the inner circumference of an inner insertion pipe(102). The tip end of an outer insertion pipe(104) is formed with a plane contact part(105). The plane contact part is formed with a plurality of saw blade parts for boring an insulation material through the rotation of the supporter. The saw blade part detaching unit comprises a safety groove(107) and a detaching groove(108). The saw blade part is opened by the pushing force of the outer insertion pipe and is embedded into the insulation material by the cutout of the detaching groove. |
