Waterproofing and draining combined roof with no vents and no leakage

Abstract

The invention discloses a waterproofing and draining combined roof with no vents and no leakage. The waterproofing and draining combined roof comprises a roof structure plate (1), a drain pipe (8) anda water guide pipe (9), wherein a waterproof layer (2), a waterproof protective layer (3), a draining layer (4), a heat insulating layer (5), a fine stone concrete layer (6) and a roof decorative layer (7) are sequentially arranged on the top surface of the roof structure plate from bottom to top; the drain pipe which penetrates through the roof structure plate, the waterproof layer, the waterproof protective layer, the draining layer, the heat insulating layer, the fine stone concrete layer and the roof decorative layer from bottom to top is flush with the top surface of the roof decorativelayer; the water guide pipe which penetrates through the roof structure plate, the waterproof layer, the waterproof protective layer from bottom to top is flush with the top surface of the waterproofprotective layer; the lower end of the water guide pipe is connected with the drain pipe through a bending pipe (10); and a check valve (11) is arranged at the connecting position of the bending pipeand the drain pipe, and the check valve is connected with the drain pipe through a hinge (12). Two waterproofing systems are arranged on the roof to prevent the pressure in the heat insulating layer from rising, strong independence is achieved, and the overall waterproof effect is good.

Description

technical field [0001] The invention relates to a combination of anti-draining and non-venting holes and non-seepage roof, which belongs to the technical field of building construction. Background technique [0002] Exhaust pipes are usually arranged on the heat insulation layer of the roof in the prior art. The exhaust pipe is not conducive to the use of roof space; the exhaust pipe is easily damaged; the exhaust pipe is also a hidden danger of water entering the insulation layer. Once the rainwater enters the insulation layer, the rainwater will pour back into the hydrophobic layer, resulting in the drainage system and the roof drainage system. If they are not connected to each other, the heat insulation effect of the heat insulation layer will lose its effect. Therefore there are deficiencies in the prior art. Contents of the invention [0003] The object of the present invention is to provide a roof that is simple in structure, easy to construct, and has a good overa...

The exhaust pipe is not conducive to the use of roof space; the exhaust pipe is easily damaged; the exhaust pipe is also a hidden danger of water entering the insulation layer. Once rainwater enters the insulation layer, the rainwater will pour back into the hydrophobic layer, resulting in the drainage system and the roof drainage system. Interconnected, the heat insulation effect of the heat insulation layer will lose its effect
