PURPOSE: To joint adjacent roof boards to a long through-clip and to increase joint strength of a joint section by improving the through-clip in fitting roofer joint construction formed by fitting and loading a cap to the joint section with pressure. ;CONSTITUTION: A through-clip 3 is constituted of a pair of right and left arms 11 and a clamping section 12 provided in the shape of an upward projection between the lower ends of the arms 11 and is formed in the shape of a gutter. A coupling section 13 is provided to the upper end of each of the arms 11 so that it is extended outward. A coupling section 8 of a roofer 4 is interlocked with the coupling section 13 to joint. The clamping section 12 is formed of a pair of leg walls 15 continued to the arms 11 and a seat wall 16 and is formed in the shape of an equal leg trapezoid. Accordingly, the leg walls 15 and arms 11 are internally inclined by clamping the seat wall 16 with a clamping device 18. Coupling sections 8 and 13 connected with the internally inclined operation are pulled near and are operated, and coupling strength is increased.;COPYRIGHT: (C)1995,JPO
