<p>&lt;P&gt;PROBLEM TO BE SOLVED: To exert efficient latent heat storage effect and keep airtight performance of an air duct for a long time by using a hollow section of a precast combined hollow floor structure as the air duct. Ž&lt;P&gt;SOLUTION: The combined hollow floor structure (1) comprises upper and lower flange concrete (2, 3) and a bent steel plate (4) of a folded plate shape. A ridge top (41) and a valley bottom (42) of a bent plate are embedded in the upper and lower flange concrete and integrated with the concrete. The air ducts (11, 13, 17) are formed by the ridge top or the valley bottom of the bent plate and the flange concrete. The latent heat storage material (10) is housed in a hollow space adjacent to the air duct. Ž&lt;P&gt;COPYRIGHT: (C)2009,JPO&amp;INPIT Ž</p> |
