The present invention relates to a double floor material for under floor air conditioning which is provided to easily install panels, which are made of different materials such as minerals and concrete shaped steel and whose mounting surfaces are composed of different shapes with each other, only by simply replacing an existing panel with a panel supporting member, which is combined with the upper part of a base, among a plurality of subsidiary members and to simply and securely fixing the panel which is mounted on the upper side, thereby improving sealing efficiency. The double floor material according to the present invention comprises: multiple bases (100) having heads (120) combined therewith to vertically move; panel supporting members (200) combined with the upper parts of the heads (120) respectively; and a panel (300) whose four corners are mounted on the upper surfaces of the panel supporting members (200) respectively; a panel fixing member for fixing the panel (300) on the base (100). Therefore, the double floor material is capable of simply installing and constructing the panels whose mounting surfaces are different from each other by simply replacing an existing supporting panel with the panel supporting members, which are selectively combined with the upper surfaces of the bases, among the subsidiary members, and has the merit of improving sealing efficiency by simply and securely pressing and fixing the panels which are mounted on the upper side thereof. |
