2. Description of the Related Art In order to connect adjacent wall panels to each other, a method is used in which a metal fitting extending over both wall panels is fixed to the back surface of the wall panels. However,
Since the work of fixing the metal fittings is performed by a worker behind the wall panel, that is, the so-called external assembly method, it is not suitable when the space behind the wall panel is small.

Therefore, various internal assembling methods have been performed in which the wall panel is erected from the inside of the unit room and is engaged with an appropriate metal fitting.

[0004]

[Problems to be Solved by the Invention]
It was developed for a frame type panel in which a decorative panel is attached to a metal frame.

By the way, in recent years, the use of a wall panel made of an inexpensive and highly rigid hollow extruded cement board has been considered. The conventional internal assembly method cannot be applied to such a hollow extruded cement board. Therefore, it is expected that the hollow extruded cement board will also be developed with an internal assembling method with good workability.
