In order to achieve the above purpose, the utility model adopts the following technical scheme:

a heat-insulating flame-retardant composite wallboard structure comprises a frame, a heat-insulating layer and a ribbed expansion net; the frame is provided with a frame and a C-shaped steel framework, a plurality of groups of C-shaped steel frameworks are fixedly connected into a whole through the frame, two C-shaped steel upright posts with opposite openings are arranged in each group of C-shaped steel frameworks, and heat insulation layers are arranged on the outer sides of webs of the C-shaped steel upright posts; the ribbed expansion net is arranged on the outer side of the heat insulation layer and is fixedly assembled with the C-shaped steel upright posts through the connecting pieces, so that a cavity structure for pouring foamed concrete on a construction site is formed between the heat insulation layer and the ribbed expansion net.

According to the heat-insulating flame-retardant composite wallboard structure, the connecting piece comprises the support and the screws, the support is a C-shaped support with flanges on two sides, and the support is fixedly assembled with the C-shaped steel upright posts through the screws arranged at the positions of the flanges on two sides.

Above-mentioned fire-retardant composite wall panel structure keeps warm, there is muscle expansion net to adopt zinc-plated belted steel in advance or 304 stainless steel, cuts to expand drawing technology shaping through the steel band and becomes the steel sheet net, evenly sets up the strengthening rib of V type groove structure on its wire side, and the distance is not more than 110mm between two adjacent strengthening ribs, has the muscle expansion net through passing the screw and the support of V type groove structure, heat preservation and "C" shaped steel stand fixed assembly.

Above-mentioned fire-retardant composite wall panel structure keeps warm, the screw is self-tapping screw.

The utility model relates to a heat-insulating flame-retardant composite wallboard structure, which is characterized in that a ribbed expansion net is arranged on the outer side of a heat-insulating layer, the ribbed expansion net is fixedly assembled with a C-shaped steel upright post through a C-shaped bracket with flanges on two sides, and a cavity structure which can be used for pouring foaming concrete in a construction site is formed between the heat-insulating layer and the ribbed expansion net; the utility model not only enhances the strength of the wallboard structure through the ribbed expansion net, but also is beneficial to hanging cement mortar on the surface of the wall body due to the net surface structure, and the production cost of the wallboard is reduced because the calcium silicate board is not needed to be laid on the wall body; the utility model discloses a job site pouring foaming concrete in cavity structure has further improved the fire-resistant grade of wallboard. Therefore, the utility model discloses both satisfied assembled building wall's heat preservation and fire prevention requirement, still solved the heat preservation and drop and be difficult for hanging the problem of cement mortar.
