<p>PURPOSE:To facilitate construction, and to improve file resistance and fire protection at joint parts by laying side by side a plurality of concrete panels on a horizontal member, and fitting incombustible material so as to cover the joints between the end parts of the panels. CONSTITUTION:A plurality of concrete panels 2 are laid side by side on a horizontal member 1. And incombustible material 4 is fitted so as to cover the upper surface of joints 3 between the end parts of adjacent concrete panels 2. Thereby the use of mortar can be made unnecessary, so that manhours for the construction can be reduced, and even if a difference in level between concrete panels 2 exists, it can be put out of sight.</p> |
