[Conventional technology]

Conventionally, as a roof like the one mentioned above,
As shown in Publication No. 70507, a plurality of metal rafters are supported and fixed on the main building material, a base material is laid between these rafters, and metal roof plates are horizontally roofed on the base material. It has been known.

In addition, as shown in Utility Model Application Publication No. 56-129433,
A base material for roof tiles is known in which a heat insulating layer having a continuous right triangular upper surface is provided on a substrate.

[Problem that the invention attempts to solve]

In the conventional roof as mentioned above, the base material is a single layer, so the heat insulation and soundproofing properties are insufficient.
If you try to use a layered base material, it will be difficult to position the rafters and the base material, and the base material and the metal roof shingles, and it will also be difficult to connect adjacent roof shingles in the direction of the eaves on the heat insulation material of the base material. Therefore, if the heat insulating material is made of foamed polystyrene or the like, it is likely to be damaged and the selection of the material is difficult.

The present invention aims to solve the above-mentioned problems and provide a roof that has sufficient heat insulation and sound insulation properties and is easy to construct.

[Means for solving problems]

The roof according to the present invention has a main building material, metal rafters in which fixing pieces protruding from the top surface are arranged at predetermined mutual intervals in the longitudinal direction, and a right triangular cross section along the eaves direction, and has heat insulation and sound insulation properties. A plurality of back-up materials made of this material are lined up in the eave ridge direction at predetermined mutual intervals that match the mutual spacing of the fixing pieces, and are fixed to the base material such as a wood wool board on the upper surface, and are secured to the eave side and ridge side edges. and a bent part is formed near the ridge side locking part of the face plate part provided between the locking parts, and an eave ridge between the eave side locking part of the face plate part and the bent part. A metal roof plate whose directional dimension corresponds to the dimension in the eave ridge direction of the backup material is provided, a plurality of the rafters are supported and fixed on the main building material, and both sides of the rafter are supported by the adjacent rafters. The base material is laid in between, and the part between the eave side locking part and the bent part of the face plate part provided on the roof board is supported along the back up material, and the face plate part is bent. The part between the part and the ridge side locking part and the ridge side locking part are arranged in the mutually spaced part of the backup material and supported on the base material, and the roof board is attached using the fastening piece. It is fixed on the rafters, and the ridge side and eave side locking parts of the roof plates adjacent in the direction of the eave ridge are locked with the mutual spacing part of the back up material to join the roof plates adjacent in the direction of the eave ridge. It is a roof made of horizontal shingles.

[Effect]

As mentioned above, the roof of the present invention consists of a metal board that is supported and fixed on the main roof, in which a plurality of back-up materials made of heat-insulating and sound-proofing materials are arranged in parallel on a base material such as wood wool board. Because it is installed between the rafters, it has better insulation and soundproofing properties than the conventional single-layer foundation material. As a mark, by aligning the mutual spacing of the backup material with the required relationship to the fastening piece and laying the base material at a predetermined position between the rafters, the mutual spacing of the fastening piece and the backup material will match. Therefore, it is possible to easily position the joint part of the roof adjacent to the eave direction in the mutually spaced part of the back-up material, that is, the positioning of the base material and the roof board is easy, and the workability during construction is good. Furthermore, since the adjacent roof panels in the direction of the eaves are joined using fastening pieces at the mutual spacing of the backup materials, the base material is made of a strong material, which provides insulation and soundproofing properties such as foamed polystyrene. Even when using a back-up material that is lightweight, inexpensive, and has excellent elasticity, the locking portion of the roof board can be securely and securely locked. Moreover, the back-up material has a right triangular cross-section along the eave ridge direction, the eave side locking part of the face plate part of the metal roof plate having the eave ridge direction dimension corresponding to the eave ridge direction dimension of the back up material, and the bent part. By accurately positioning the parts between the two, it is possible to ensure that there is no gap between them, resulting in excellent soundproofing during rainstorms.
