Description of the Related Art In recent years, most of exterior structures such as a horizontal roof and a horizontal exterior wall have a support member such as rafters arranged on a building frame at predetermined intervals, and a heat insulating board or the like is provided between the support members. Many are laid and an exterior material is constructed on the support member. Each part is different from the one by the former field molding,
Standardized and factory-produced, the heat insulation and strength performance are stabilized and the workability is excellent. However, if the building is not a small building like a wooden house,
Since the support member is made of metal from the viewpoint of strength performance, there is a problem that the portion where the metal rafter is laid becomes a thermal bridge on a heat insulating structure. In order to solve this problem, as shown in Japanese Utility Model Publication No. 1-2711, there is a method of inserting a heat insulating material into a lower opening space of a supporting member (metal rafter) to solve a thermal bridge problem. is there.
However, even in such a configuration, since the inside and outside of the metal rafter and the heat insulating material layer are thermally connected to each other by the side portions of the metal rafter, the drastic thermal bridge problem has been solved. Absent.

として高い効率を得られる。As a result, the rafter 1 itself between the backup materials 8 having high heat insulation has a combined structure in consideration of heat insulation, so that a thermal bridge effect does not occur and the heat insulation as a whole is excellent. . In addition, although the low-density backup material 8 is used, each leg 8c rests on the surface of the base material 6, and the entire surface plate 9c of the roofing shingle 9 is a step-like portion 8a.
Can be supported and backed up by this stepped part 8a
And the tunnel-like portion 8b in a back-to-back configuration is present in the structure, and its existence is secured by the legs 8c mounted on the surface of the field material 6, so that the tunnel-like portion 8b is integrally formed. There is some manufacturing advantage, and the structural weight of the backup material 8 itself can be greatly reduced. Since the continuous space S composed of the tunnel-like portions 8b of each backup material 8 communicates between the ridge side and the eave side, high efficiency can be obtained as a heat insulating space and a space for preventing internal dew condensation.

材の取り付け強度が高い。A. According to claim 1, the first member and the second member made of metal are:
Since the third member made of resin is interposed so as not to make direct contact, it is possible to almost completely eliminate the thermal bridge problem in the conventional heat insulating structure. Since the cross-sectional strength is low when the component members are in individual states, the bending process can be easily performed. Since the first and second members as the strength members are arranged vertically and integrated by the third member, the same strength as that of the conventional rafter can be obtained. B. According to claim 2, each constituent member can be firmly integrated. Since the engagement relationship between the hook-shaped engaging portion and the engaged portion is strong, the hook-shaped engaging portion does not come off even if subjected to a twisting action or the like. C. According to the third aspect, the workability is improved and the strength performance is also improved. D. According to claim 4, when assuming fixing by a fixing tool such as a screw, if the holding portion is of an integrated type, the screw may break when subjected to strong lateral vibration, but if the holding portion is a separate type, the screw may be broken. Since the danger is mitigated, seismic performance against earthquakes and the like is improved. E. FIG. According to claim 5, the heat-insulating support member between the heat-insulating materials is insulated by the action of the third resin member, similarly to the heat-insulating material interposed between the skeleton and the exterior material.
Since the first and second metal members as the vertical strength members of the heat insulating support member are separated by the third resin member so as not to come into direct contact with each other, the problem of the thermal bridge in the conventional exterior heat insulating structure can be solved. It can be almost completely eliminated.
Since the cross-sectional strength of each component of the heat-insulating support member is low in each state, the bending process can be easily performed. The heat-insulating support member interposed between the skeleton and the exterior member has metal first and second members as strength members arranged vertically and integrated with a third member, so that a conventional support member is used. And the strength of attaching the exterior material to the skeleton is high.
