REMOVABLE SET ANCHOR BOLT
The present invention relates to a removable set anchor bolt including: a fixing bolt which has a screw thread along an outer circumference, and has a taper part (110) whose diameter increases gradually as going to the end on the bottom, and is installed in a hole of a concrete structure; a sleeve (200) which is formed in a cylinder shape, is inserted into the fixing bolt (100), and comprises an extended part (220) which closely adheres to the inner circumference of the hole of the concrete structure by being spread outward when the extended part is geared to the taper part (110) by providing a number of cutting grooves (210) up and down on the bottom; and an elastic member (300) which supports the bottom of the fixing bolt (100) by being installed on the bottom of the hole of the concrete structure, and is lowered as being compressed when an external force above a fixed intensity is applied up and down. When the top of the fixing bolt (100) is hit by the external force above the fixed intensity in order to remove the fixing bolt (100) from the hole of the concrete structure, the elastic member (300) is compressed and lowered and then the taper part (110) of the fixing bolt (100) is taken out below the extended part (220) of the sleeve (200). Under the state that the taper part (110) of the fixing bolt (100) is taken out below the extended part (220) of the sleeve (200), the fixing bolt (100) is removed from the hole of the concrete structure.
