Detailed Embodiment
[0022] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0023] Please refer to Figure 1 , a waterproof and heat-insulating metal roof structure, including: a roof purlin 1, a decorative bottom plate 2, a decorative panel 8, a heat-insulating layer 3 and a support profile plate 6.
[0024] The roof purlin 1 is fixed to the building wall or roof. The roof purlin 1 is a hollow round-corner rectangular steel pipe. The decorative bottom plate 2 is fixed to the roof purlin 1. A conversion purlin 4 and a heat-insulating layer 3 are provided on the decorative bottom plate 2. The conversion purlin 4 is fixed to the decorative bottom plate 2 and is located directly above the roof purlin 1. The heat-insulating layer 3 is fixed to the decorative bottom plate 2. A plurality of upper keel strips 7 parallel to the conversion purlin 4 are provided on the conversion purlin 4. The decorative panel 8 is supported on the upper keel strips 7. The decorative panel 8 and the decorative bottom plate 2 are respectively located on the inner and outer sides of the main body of the roof structure, thereby comprehensively improving the aesthetics of the roof structure.
[0025] A vapor barrier film 31 is provided between the decorative bottom plate 2 and the heat-insulating layer 3. The vapor barrier film 31 is attached to the upper surface of the decorative bottom plate 2 or the lower surface of the heat-insulating layer 3. A waterproof film 61 is also attached to the surface of the support profile plate 6 away from the heat-insulating layer. The vapor barrier film 31 and the waterproof film 61 can prevent the intrusion of outside moisture and inside steam into the heat-insulating layer 3, improve the service life of the heat-insulating layer 3, and improve the heat-insulating effect of the roof structure.
[0026] The supporting profile plate 6 is a profiled plate in a concave-convex form, with a shape of a corrugated plate structure. It is provided with continuous upward grooves and downward grooves. The upward grooves and downward grooves are arranged at intervals. Both the upward grooves and downward grooves are strip-shaped and perpendicular to the conversion purlin 4. The corrugated plate structure can improve its own structural strength. At the same time, the downward groove structure of the supporting profile plate 6 can form a rainwater diversion structure. When external rainwater enters the roof structure, the diversion structure of the supporting profile plate 6 can quickly divert the rainwater out, preventing the rainwater from invading the thermal insulation layer 3 of the roof structure, thereby improving the waterproof and thermal insulation characteristics of the roof structure. The structure of attaching the waterproof film 61 to the supporting profile plate 6 of the profiled plate in a concave-convex form can meet the secondary waterproof standard.
[0027] Preferably, the conversion purlin 4 is supported by a plurality of upper keel strips 7 parallel to the conversion purlin 4, and the decorative panel 8 is supported on the upper keel strips 7. A lower keel strip 5 is further provided below the supporting profile plate 6. The lower keel strip 5 is fixed to the conversion purlin 4, and the lower keel strip 5 supports the lower surface of the downward groove of the supporting profile plate 6. Fastening screws are provided on the upper keel strip 7. The lower ends of the fastening screws pass through the supporting profile plate 6 and are threadedly connected to the upper keel strip 7. The upper and lower sides of the supporting profile plate 6 are respectively fixed by the upper and lower keel strips 5, which can improve the overall strength of the roof structure and simplify its structural configuration, making it have the advantages of being easy to install and durable.
[0028] Preferably, the edge of the decorative bottom plate 2 has a folded edge portion 21 that bends upward. A support seat 22 is further provided on the decorative bottom plate 2. The support seat 22 is in a "channel" shape structure. The two side edges of the support seat 22 are connecting portions, and the middle part bulges upward to form a support portion. The height of the support portion is flush with the height of the folded edge portion 21. The connecting portion is fixed to the decorative bottom plate 2, and the support portion is used to support the conversion purlin 4. The support seat 22 can facilitate the installation of the conversion purlin 4.
[0029] Preferably, both the decorative bottom plate 2 and the decorative panel 8 are made of weathering steel (weathering steel is atmospheric corrosion-resistant steel, belonging to low-alloy high-strength structural steel plates). The weathering steel material can form a crystal-dense layer on the surfaces of the decorative panel 8 and the decorative bottom plate 2. This dense layer is very firmly combined with the base layer. This stable rust layer (crystal-dense layer) can, to a certain extent, block the intrusion of water vapor and harmful ions in the atmosphere, thereby greatly reducing the rusting rate of the weathering steel and extending the service life of the internal structures of the decorative panel 8 and the decorative bottom plate 2. Moreover, the surface of the weathering steel does not need to be painted, and there is no problem of paint aging, greatly reducing the maintenance cost.
[0030] Preferably, the decorative panel 8 is fixed on the upper keel strip 7 by welding. The support profile plate 6, the upper keel strip 7 and the lower keel strip 5 are all made of steel, and galvanized layers are provided on the surfaces of the support profile plate 6, the upper keel strip 7 and the lower keel strip 5.

It should be understood that the use of the orientation words should not limit the scope of protection claimed in this application.
[0032] Without conflict, the above-mentioned embodiments and the features in the embodiments in this text can be combined with each other.
[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model.
