Repair material dispensing jig

Abstract

This invention provides a repair material dispensing jig that ensures ease of use by allowing the repair material to be easily dispensed with less pressure than conventional methods, while also preventing the head component from easily detaching from the nozzle component. [Solution] A repair material dispensing jig 100 comprising a nozzle member 1 which is cylindrical and has a cartridge C containing repair material attached to its base end, and has a through hole whose inner diameter decreases from the base end to the tip, and a head member 2 which is made of a material that is more elastic than the nozzle member, has a through hole in the center, and whose base end is detachably fitted to the outside of the tip of the nozzle member via a locking member 3, wherein the repair material supplied from the cartridge passes through the inside of the nozzle member and is discharged from the tip surface 23a of the head member which is in close contact with the location where a crack has occurred in the structure, wherein the locking member has irregularities formed radially on the inner surface of the head member and / or the outer surface of the nozzle member.

Claims

1. A nozzle member having a cylindrical shape, with a cartridge containing repair material attached to its base end, and a through-hole whose inner diameter decreases from the base end to the tip, It comprises a head member made of a material more elastic than the nozzle member, having a through hole in the center, and whose base end is detachably fitted to the outside of the tip of the nozzle member via a locking member, A repair material dispensing jig in which the repair material supplied from the cartridge passes through the inside of a nozzle member and is discharged from the tip surface of a head member that is in close contact with the location where a crack has occurred in a structure, A repair material dispensing jig wherein the locking member has irregularities formed radially on the inner circumferential surface of the head member and / or the outer circumferential surface of the nozzle member.

2. The repair material dispensing jig according to claim 1, wherein the locking member comprises a convex portion formed on one of the inner circumferential surface of the head member and the outer circumferential surface of the nozzle member, and a recess formed on the other, and the head member is locked to the tip of the nozzle member by the interlocking of the convex portion and the recess.

3. The repair material dispensing jig according to claim 1, wherein the shape of the base end of the head member is such that it fits snugly against the outside of the tip of the nozzle member without any gaps.

4. The repair material dispensing jig according to claim 1, wherein the shape of the nozzle member is a rounded cone shape at the tip.

5. The repair material dispensing jig according to claim 1, wherein the shape of the surface of the head member that contacts the location where a crack has occurred in the structure has a major axis and a minor axis.

6. The repair material dispensing jig according to claim 1, wherein the repair material contains epoxy resin.
