Description

Technical Field

[0001] The utility model relates to the field of roofing waterproofing, and particularly to a waterproof roofing system. Background Art

[0002] For example, a waterproof roofing as disclosed in Chinese Utility Model CN 203429912 U includes a roof and multiple layers of waterproof coiled material monomers. The surface of the waterproof coiled material monomer has a structure of long strip-shaped grooves, and the grooves on the surfaces of the contacting waterproof coiled material monomers are vertically or crosswise arranged; a construction method of a waterproof roofing includes cleaning the roof, pouring waterproof glue, and laying waterproof coiled materials. The waterproof coiled materials used are multiple layers of waterproof coiled material monomers, and the surfaces of the multiple layers of waterproof coiled material monomers are coiled materials with long strip-shaped grooves, and the grooves on the surfaces of the contacting waterproof coiled material monomers are vertically or crosswise arranged. It mainly uses laying waterproof coiled materials for waterproofing, but the laying of the waterproof coiled materials is prone to slipping and is not firm enough. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a waterproof roofing system which is firmly installed, not prone to slipping, can not only waterproof but also heat-insulate, and is beneficial to building energy conservation.

[0004] To solve the above problems, a waterproof roofing system is adopted, which includes:

[0005] Purlins, with multiple of them arranged at intervals;

[0006] Inner corrugated steel sheets, which are laid on the purlins;

[0007] Vapor barrier layer, which is laid on the inner corrugated steel sheets;

[0008] Supports, which are fixedly installed on the inner corrugated steel sheets;

[0009] Lining purlins, which are laid at intervals on the supports;

[0010] Rock wool board heat-insulation layer, which is laid on the lining purlins;

[0011] Plastic-steel tiles, which are laid on the rock wool board heat-insulation layer;

[0012] Fixing screws, which fix the plastic-steel tiles on the lining purlins;

[0013] Nail head caps, which cover the fixing screws and are fixed on the plastic-steel tiles.

[0014] With such a structure, the support member is fixed to the inner corrugated steel sheet by bolts. The support member helps to raise the height to accommodate the thickness of the rock wool board insulation layer; the purlin further raises the cotton board insulation layer, facilitating the subsequent pressing of the rock wool board insulation layer, making the rock wool board insulation layer thinner and then fixing it, making it more firm; the fixing screws are beneficial for firmly fixing the plastic steel tile through the rock wool board insulation layer; the nail head cap covers the fixing screws to achieve a waterproof effect.

[0015] As a further improvement of the present utility model, a glue layer is provided on the upper bottom surface of the nail head cap, an inner channel sealing ring is provided outside the glue layer, and an outer channel sealing ring is arranged at intervals outside the inner channel sealing ring. A polyurethane foam layer is arranged between the inner channel sealing ring and the outer channel sealing ring, and an injection hole is opened at the corresponding position on the top surface of the nail head cap.

[0016] With such a structure, the inner channel sealing ring protects the glue layer from losing its viscosity due to the influence of water flow. After the inner channel sealing ring and the outer channel sealing ring form an interval, by wetting the surface of the nail head cap and then injecting the polyurethane foam filler, it can quickly foam to form a polyurethane foam layer that can fill gaps and plug leaks, further improving the sealing performance and waterproof performance.

[0017] As a further improvement of the present utility model, a groove is arranged in the middle of the inner channel sealing ring and the outer channel sealing ring.

[0018] With such a structure, the combination of the inner channel sealing ring, the outer channel sealing ring and the polyurethane foam layer is better.

[0019] As a further improvement of the present utility model, the plastic steel tile is a TPF plastic steel tile.

[0020] As a further improvement of the present utility model, the thickness of the purlin is not less than 2.5 mm.

[0021] As a further improvement of the present utility model, the support member is in a U-shape and its thickness is not less than 2.5 mm.

[0022] As a further improvement of the present utility model, a sealing ring is laid on the injection hole, a pressing block is arranged on the sealing ring, and a limiting ring is arranged at the end of the pressing block. The limiting ring is threadedly connected to the convex part of the nail head cap.

[0023] With such a structure, it is convenient to seal the injection hole.

[0024] The present utility model is firmly installed and not easy to slip off. It can not only prevent water but also keep warm, which is beneficial to building energy conservation. Description of the Drawings
