HEAT INSULATING AIRTIGHT STRUCTURE OF ROOF, AND STRUCTURE OF HEAT INSULATING MATERIAL

摘要

PURPOSE: To improve working efficiency, shorten the construction period, and enhance the interior airtightness by nipping a plate heat insulating material or heat insulating material worked into plate between girders built vertically to the interior side surface of the gradient roof of a wooden building. ;CONSTITUTION: A plate heat insulating material 1 is inserted between girders 12, 12 built vertically to the interior ridge-side side surface and eaves-side side surface of the roof rafter 5 of a gradient roof. The insertion is performed by inserting the ridge-side end part of the heat insulating material 1 to the contact of the eaves-side side surface of the girder 12 with the roof rafter 5, and using this as a supporting point to push up the eaves-side end part. When the length between the girders 12, 12 is shorter than a schedule, the protruding part is moved to the lower part of the girder 12 and fixed. When longer than the schedule, a cushioning material is put between them to lower the ridge-side supporting point, and the eaves-side end part is pushed up and fixed. Further, the heat insulating material 1 is set slightly longer to utilize the elastic force of the heat insulating material 1 body, or a packing material is put between the butting surfaces of the heat insulating material l and the girder 12. The heat insulating material 1 is pushed up from under, and a pr is added to the butting surfaces to enhance airtight performance.;COPYRIGHT: (C)1995,JPO
