[0002]

2. Description of the Related Art Such a roof material mounting structure includes:
2. Description of the Related Art Conventionally, a ridge side end of a metal roofing material is locked by a metal fitting (for example, a hanger) for mounting on a ground surface side, and the metal roofing material is fixed one by one, or a ridge side of a metal roofing material. The part where the molded part and the eave-side molded part of the metal roofing material adjacent to the ridge side are engaged with each other is locked by a special hook attached to the ground surface side, and the metal roofing material is fixedly attached. (See, for example, JP-A-63-22952).

[0003]

However, in the above-mentioned conventional roofing member mounting structure, when the roofing is completed and all the metal roofing members are once mounted on the ground, the solar cell is mounted. When a defect occurs in a part or a connection portion of the solar cell and it is necessary to partially remove a metal roof material corresponding to the failure occurrence portion, it is difficult to partially remove the metal roof material. There was a problem of becoming. In addition, there is a problem that a laborious operation is required, for example, a metal roof material must be attached using a special tool. In addition, there is a problem that the allowable dimensional error in the roof inclination direction at the time of mounting the metal roofing material is limited. The present invention has been made in view of such a situation, and an object of the present invention is to provide means capable of resolving the above-mentioned various problems in the conventional roofing material mounting structure at once.

[0004]

The roof structure according to the present invention has a characteristic structure (hereinafter referred to as the structure of the present invention) in which a metal roof material having a solar cell adhered to a surface side is mounted on a ground. Mounting structure for a roofing material, wherein the metal roofing material has a falling portion formed by bending an eaves-side end downward and a rising portion formed by bending a ridge-side end upwards; On the other hand, an elastic fitting having a displacement portion capable of being elastically displaced up and down in the vicinity of the back surface of the metal roofing material in the mounting posture can be detachably attached with screws that can be operated from the outside of the roof, and the metal roofing material can be placed. At the same time, a fixing part capable of fixing the rising part and the falling part is attached to the ground, and a locking part capable of locking the displacement part by climbing over the elastic displacement of the displacement part is provided on the fixing part. , Sideways The draining board which can be drained by receiving water leakage from their clearance with possible placing the ends of the metal roofing material adjacent lies in that is configured to be freely carried by said fixed bracket.

[0005]

According to the structure of the present invention having the above-mentioned characteristic configuration, the metal roofing material with the falling part to which the elastic fitting having the displacement part is attached is slid onto the fixing fitting and the draining plate. , By pushing from the outside of the roof,
An elastic displacement can be generated in the displacement portion, and the displacement portion can be caused to go over the locking portion of the fixing bracket based on the elastic displacement. Then, based on the overcoming, the displacement portion is locked by the locking portion of the fixing bracket, so that the metal roofing material can be easily attached and fixed to the ground. Further, since the metal roofing material is mounted and fixed on the ground surface only by the locking by the locking portion in a state where the metal roofing material is placed on the fixing bracket and the drain board, the metal roofing material is fixed. The permissible dimensional error at the time of installation of the vehicle has flexibility in the roof inclination direction. Moreover, since the elastic fitting is detachably attached to the falling portion with screws that can be operated from the outside of the roof, once all the metal roofing materials are once attached to the ground, some of the metal roofing materials are removed. When it is necessary to remove (for example, when a defect occurs in some solar cells or their connection parts and it becomes necessary to partially remove the metal roofing material corresponding to the defective part), By removing the screw from the outside of the roof, the locked state by the locking portion is released, and the part of the metal roofing material can be easily removed.

[0006]

Accordingly, the above-mentioned various problems in the conventional roof material mounting structure, that is, the conventional problem that it takes time to mount the metal roof material, and the allowable dimensional error in the roof inclination direction when mounting the metal roof material. And the conventional problem that it is difficult to partially remove a metal roofing material after roofing is difficult. In addition, in addition to having the above-mentioned characteristic configuration, when the vertical mounting position of the screw with respect to the falling portion is set to a position below and close to the locking portion in a state where the displacement portion gets over, the fixing is performed. The locking of the metal roofing material with respect to the locking portion of the metal fitting is performed not only between the displacement part of the elastic fitting attached to the metal roofing material (more specifically, the displacing part in the overriding state) but also the elastic fitting. Since the metal roofing material is also generated between the screw attached to the falling part for mounting, even when a lifting pressure generated intensely at the time of a typhoon or the like acts on the metal roofing material, the metal roofing material is fixed to the metal roofing material. There is an advantage that detachment from the metal fittings 5 is suppressed, and the durability is improved.
