To improve the executability without damaging tiles by providing a circular guide having a specified value of diameter and to be fitted in a joint part of tile panels in both sides of a nailing part of a nailing machine, and providing a buffer material in a root part thereof.
Circular guides 8 are provided in both sides of a nailing part 10 provided at a tip 7 of a nailing machine, and diameter thereof is set at 4-15 mm in consideration of the tile dimensional accuracy. Driving is performed by the compressed air, and a nail is driven through the center of the nailing part 10. A space between a right and a left guides of the guide 8 is set at 18 mm, guide length is set at 4 mm, and guide diameter is set at 5 mm, and the guide is fitted without generating a contact with a joint bottom of a lateral joint part of tiles 2, and a rubber member 9 having a thickness at 1 mm is provided as a buffer material in a direct contact part with the tile so that the nail can be forced fed into the joint bottom of the tile panels without damaging the finishing tiles. With this structure, the nail can be securely driven to the joint bottom by one drive, and generation of damage of the tiles can be prevented, and generation of crack of the tile can be prevented by the buffer material.
