The traditional roof panel is a sandwich panel composed of a color steel plate, aluminum alloy or polyurethane plate as a hard layer wrapped with an insulation layer. In order to achieve environmental protection and energy saving, the surface materials such as roof tiles or photovoltaic panels are usually installed after the roof panel is laid. The installation work requires the installation frame of the roof tiles or photovoltaic panels to be installed on site by bonding or bolting, which is time-consuming and labor-intensive, with a long operation cycle. In addition, the traditional roof panels have weak strength and bearing capacity and a short service life. Utility Model Content

The key point is that it also includes an outer frame skeleton arranged at the edge of the sandwich panel and a group of inner frames arranged at intervals on the sandwich panel. The inner frame includes a group of connecting ribs, a lower chord, an upper chord and a connecting frame. The connecting ribs are arranged in pairs between the lower chord and the upper chord and form a triangular structure with the lower chord or the upper chord. Adjacent lower chords and adjacent upper chords are connected by means of connecting frames to form an integral inner support frame of the roof panel.

[0006] The outer end of the upper chord protrudes from the outer side surface of the sandwich layer plate.

[0007] The sandwich layered plate comprises a heat-insulating fireproof layer, a heat-insulating layer, and a protective layer in sequence from the inside to the outside, and a fireproof protective layer is further arranged at the bottom of the heat-insulating fireproof layer.

[0008] The fireproof protective layer is a cement fiber board layer, and the heat-insulating fireproof layer is a sprayed polyurethane layer.

[0009] The protective layer is a waterproof concrete layer, and a waterproof roll material or a waterproof coating is arranged outside the waterproof concrete layer.

[0010] A steel mesh is arranged in the waterproof concrete layer.

[0011] The outer frame is C-shaped steel.

[0012] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1-4As shown, the assembled roof panel includes a sandwich layer panel 1. The key point is that it also includes an outer frame skeleton 2 arranged at the edge of the sandwich layer panel 1 and a group of inner frames 3 arranged at intervals on the sandwich layer panel 1. The inner frame 3 includes a group of connecting ribs 31, a lower chord 32, an upper chord 33 and a connecting frame 4. The connecting ribs 31 are arranged in pairs between the lower chord 32 and the upper chord 33 and form a triangular structure with the upper chord 33. Pairs of connecting ribs 31 are arranged on both sides of the lower chord 32 and the upper chord 33. Adjacent lower chords 32 and adjacent upper chords 33 are connected by means of the connecting frame 4 to form an integral internal support frame of the roof panel, which effectively improves the strength and supporting capacity of the roof panel. The outer frame skeleton 2 is C-shaped steel, and the outer frame skeleton 2 wraps and protects the edge of the sandwich layer panel 1. The setting of the connecting rib 31 enhances the connection performance between the lower chord 32 and the upper chord 33, and at the same time enhances the connection strength between the inner frame 3 and the sandwich layer panel 1. The setting of the inner frame 3 significantly improves the strength and bearing capacity of the sandwich layer panel 1, which helps to extend the service life of the roof panel, and meets the needs of storing unlaid roof tiles or photovoltaic panels on the roof panel, while also being able to carry workers to walk and work normally on the roof panel.

[0021] The lower chord 32 and the upper chord 33 are square steel or C-shaped steel. In this embodiment, the lower chord 32 and the upper chord 33 are preferably square steel.

[0022] The outer end 331 of the upper chord 33 protrudes from the outer side surface 11 of the sandwich layer plate 1. The protruding outer end 331 of the upper chord 33 serves as a frame required for the installation of roof tiles or photovoltaic panels, and can be directly used to fix the roof tiles or photovoltaic panels, eliminating the process of on-site installation of the frame, effectively improving the installation efficiency of the roof tiles or photovoltaic panels, and the frame and the roof panel are an integrated structure, which helps to improve the installation stability of the roof tiles or photovoltaic panels and reduce the maintenance frequency.

[0023] The sandwich layer plate 1 includes a thermal insulation and fireproof layer 12, a thermal insulation layer 13 and a protective layer 14 from the inside to the outside, and a fireproof protective layer 5 is also arranged at the bottom of the thermal insulation and fireproof layer 12; wherein the fireproof protective layer 5 is a cement fiber board layer, which is fireproof and insulating, waterproof and moisture-proof, heat-insulating and sound-insulating, and is not easy to deform and has a long service life; the thermal insulation and fireproof layer 12 is a sprayed polyurethane layer, the sprayed polyurethane has strong integrity and is firmly bonded to the base surface, so that the cement limiting plate layer and the thermal insulation layer 13 are firmly bonded, and are waterproof, heat-insulating and corrosion-resistant; the protective layer 14 is a waterproof concrete layer, which has a waterproof effect and high strength at the same time, and a waterproof roll or waterproof coating 16 is also arranged outside the waterproof concrete layer. In this embodiment, the waterproof coating 16 is preferred, and the outer end 331 of the upper chord 33 protrudes from the surface of the waterproof coating 16; the inner side of the sprayed polyurethane is flush with the inner side of the outer frame skeleton 2, and the fireproof protective layer 5 is a cement fiber board, and the cement fiber board is fitted with the bottom of the sprayed polyurethane.
