<P>PROBLEM TO BE SOLVED: To provide a junction structure of heat insulation ceiling panels, which can maintain heat insulation of the heat insulation panel with minimum separation of a lower face plate and can maintain airtightness and heat insulation of a junction between the heat insulation panels. <P>SOLUTION: A junction structure of heat insulation ceiling panels allows insulation panels P comprising an insulation core 20 and surface plates 1 and 2 bonded to top and bottom of the core to be joined to each other through an incombustible joint sealant 25. When the lower surface plate 2 of at least one of the heat insulation panels is displaced downward at a junction of the insulation panels, engaging pieces 2A and 2B formed at the lower surface plate are engageable to engaging receiving parts 1A and 1B formed at the upper surface plate 1 of the heat insulation panels, or an engaging piece 2C formed at the lower surface plate 2 of one of the insulation panels P1 is engageable to an engaging projection 2D formed at the other insulation panel P2 or engageable to the joint sealant. <P>COPYRIGHT: (C)2012,JPO&INPIT |
