ASBESTOS LAYER COVERING STRUCTURE OF ROOFING MATERIAL FOR BUILDING

PROBLEM TO BE SOLVED: To provide an asbestos layer covering structure of a roofing material for a building, which facilitates construction work, and which has proper handleability and excellent durability. SOLUTION: This asbestos layer covering structure is arranged inside the roofing material 11 for the building, which is formed in such a shape as to have a trapezoidal cross section and which has an asbestos layer formed on its inner surface, so as to cover the asbestos layer 13. More specifically, a supporting beam 14, which has a supporting piece 15 formed in such a shape as to have a trapezoidal cross section and elongated sideward along both side bottoms and which has an end supported by a structural skeleton, is arranged inside the roofing material 11. A locking plate 21 is turnably supported on the top plate 20 of the supporting beam 14. The supporting beam 14 abuts on the inner surface of the roofing material 11 by being turned in the state of being arranged inside the roofing material 11, so as to suppress the upward movement of the supporting beam 14. Additionally, a covering ceiling plate 17 with high rigidity is placed on the opposed supporting pieces 15 of the supporting beams 14, so as to cover the asbestos layer 13.
