The invention discloses a roof
eaves board, relates to modeling, construction and mounting construction of the roof
eaves board, and aims at the problems of single roof modeling and the like. The roof
eaves board is characterized in that firstly, a slope of the eaves board is smaller than that of a roof board, and an overhanging eaves type eaves board modeling is formed; secondly, a corner eaves board in the position of an inclined roof
ridge at the corner of a roof corner is bent upward, and a structure of an overhanging eaves type modeling of the corner roof
ridge is formed; thirdly, an anti-shearing and anti-pulling net is arranged in the light and thermal-insulation roof eaves board; fourthly, reinforcing steel bars, anchor bolts and the anti-pulling net are used for mounting and prefabricating the light and thermal-insulation roof eaves board; fifthly, a first thermal-insulation bridge-
cut-off structure of the roof eaves board is characterized in that a bearing is arranged on an outer wall bearing member, a truss or a net rack is mounted on the bearing, then the bearing is connected with a
coupling beam, and the light roof eaves board is connected with the
coupling beam; sixthly, a second thermal-insulation bridge-
cut-off structure of the roof eaves board is characterized in that a
cantilever beam is arranged on the outer wall bearing member, and the light roof eaves board is located on the
cantilever beam; seventhly, drain holes are formed in the roof eaves board; and eighthly, the self-waterproof roof eaves board has a waterproof
thermal insulation layer. The roof eaves board is attractive in modeling, low in manufacturing cost and convenient to construct.
