Embodiment 1

[0027] A wind-resistant and waterproof stepped steel plate roof structure, its structure see figure 2 As shown, it includes a suspended ceiling gypsum board 1, a light steel roof truss 2, and a composite board 10 with a slope laid on the light steel roof truss 2. The composite board 10 is also provided with stepped boards 11 inserted in sequence along the direction of its slope. The upper and lower ends of the step plate 11 respectively form a female end 14 and a male end 13. When the step plate 11 is paved, the male end 13 of the upper step plate 11 presses the female end 14 of the lower step plate 11. , and fastened and plugged with each other, and the buckled and plugged parts of the male buckle end 13 and the female buckle end 14 are also connected to the composite board 10 through a hidden detachable structure.

[0028] See image 3 with Figure 4 As shown, the upper end of the stepped plate 11 is bent upwards and then bent inwards to form a U-shaped structure, which i...

Abstract

The invention relates to a wind-resistant and waterproof step steel plate roof structure. The wind-resistant and waterproof step steel plate roof structure comprises a ceiling gypsum board, a light steel roof truss and a composite board with a slope laid on the light steel roof truss, wherein step boards which are sequentially connected in an inserted mode in the slope direction of the composite board are further arranged on the composite board, and the upper end and the lower end of each step board form a female buckle end and a male buckle end correspondingly; when the step boards are paved, the male buckle ends of the upper step boards press the female buckle ends of the lower step boards, the male buckle ends and the female buckle ends are buckled and connected in an inserted mode, and the buckled and inserted connection portions of the male buckle ends and the female buckle ends are further connected with the composite board through a hidden detachable structure. Compared with the prior art, the wind-resistant and waterproof step steel plate roof structure is attractive in appearance, easy, convenient and rapid to install, good in waterproof performance, good in heat preservation and heat insulation performance, high in strength and high in wind resistance, and the cost is effectively saved.

Description

technical field [0001] The invention belongs to the technical field of roof systems, and relates to a windproof and waterproof stepped steel plate roof structure. Background technique [0002] The traditional cold-formed thin-walled steel structure roof system consists of suspended ceiling gypsum board 1, secondary purlin 6, light steel roof truss 2, OSB board 3, waterproof membrane 4 and asphalt tile 5, and also includes cornice 7 and gutter 8, see figure 1 . This kind of roof lacks internal and external insulation systems, and its thermal insulation performance is poor; the roof lacks an external insulation system, and its sound insulation performance is poor. [0003] In order to improve its thermal insulation, heat insulation, waterproof and / or windproof properties, Chinese patent CN206599896U discloses a new type of cold-formed thin-walled terracotta tile roof system, which includes gypsum boards, secondary purlins, and cold-formed thin-walled steel trusses , OSB boar...
