PURPOSE:To provide a sufficient engagingly-stopping strength by forming an internal angle joiner by the combination of a receiving member provided with two projected pieces on L-shaped nailing parts and having a female type engaging groove with a T-shaped covering member having a male type inserting piece. CONSTITUTION:An internal angle joiner is formed by a receiving member and a covering member. The receiving member is provided with a female side, namely an insert-engaging groove 1 and nailing parts 2, while the covering member is formed by a male side, namely an insert-engaging piece 7 and decorative surfaces 6. The receiving member is nailed directly to an internal angle part, and the end part of a panel for building construction is adapted to abut on the receiving member to be fixed outside the insert-engaging groove 1. The male type insert-engaging piece 7 of the covering member is then inserted into the female side insert-engaging groove 1, and the male type insert-engaging piece 7 is engaged with the insert-engaging groove by providing number of engagingly-locking projection on it by a cut and raised piece 8. Thus, the engaging-stopping is performed through the notching, and thus the covering member is easily inserted, but hard to be disengaged. |
