Usually, a metal roof plate is directly fixed to the skeleton member, and the roof is constructed. In this case, since the skeleton members are arranged at a considerable interval, the metal roof with the skeleton member as a base has a structure in which only one thin metal plate defines the inside and outside, there is almost no heat insulation effect, and the strength Even if it is excellent, the roof becomes hot in summer and cold in winter. In addition, when building a metal roof on such a skeletal member, the snow on the roof melts, the water freezes, it becomes a dam state, the water from the snow melts back into this dam and soaks into the back of the ceiling, etc. There is a problem that “smearing” that causes water leakage is likely to occur.
The present invention aims to solve the above problems.

上記目的を達成するため本発明は、同一平面上に所定の間隔を存して配列された複数本の細長い金属製の骨格部材と、前記骨格部材の複数の所定位置に固定配置された吊り子と、帯状の長尺状の平板部の両側部に該平板部に対して直角な立ち上がり部が形成され、該立ち上がり部の上部が水平方向と垂直方向に屈折されて係合部が形成され、前記骨格部材上に複数配列され、互いの隣接する係合部が前記吊り子を介して係合する下地屋根板と、前記下地屋根板の各係合部の上部に載置され、該下地屋根板との間に各立ち上がり部ごとに区画された空気室を形成する1枚又は複数枚の断熱下地板と、前記断熱下地板の上面に配設された金属製の屋根板とを備え、前記空気室の開口端を屋外に対向させ空気室を屋外と連通させたものである。
また本発明は、前記各下地屋根板の各平板部に通気孔を設け、前記空気室と前記下地屋根板の下方側を連通したものである。
また本発明は、前記骨格部材の下方に天井板を配設し、該天井板に通気穴を設け、該通気穴にファンを取り付け、前記空気室内の空気を前記天井板上方の屋根裏に導き、該屋根裏の空気を前記ファンによって室内に導くようにしたものである。
また本発明は、前記各下地屋根板の立ち上がり部に通気孔を設け、空気室間を連通させたものである。
To achieve the above object, the present invention provides a plurality of elongated metal skeleton members arranged at a predetermined interval on the same plane, and a suspension fixedly disposed at a plurality of predetermined positions of the skeleton member. And a rising portion perpendicular to the flat plate portion is formed on both sides of the belt-like long flat plate portion, and the upper portion of the rising portion is refracted in the horizontal direction and the vertical direction to form an engaging portion, A plurality of base frames arranged on the skeleton member, and the adjacent roofs engaged with each other via the suspension, and the base roofs are placed on top of the respective engaging parts of the base roofs. One or a plurality of heat insulating base plates forming an air chamber partitioned for each rising portion between the plate and a metal roof plate disposed on the upper surface of the heat insulating base plate, The open end of the air chamber faces the outside and the air chamber communicates with the outside.
