Problems solved by technology

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

Embodiment

[0020] In the specific implementation of this example, if figure 1 Shown: When pouring the roof structural slab, a certain slope is directly poured. The roof structural board should be compacted and calendered when the raw slurry is troweled, and the roof structural board is directly used as the base layer of the waterproof layer. There is no need to set a leveling layer on the roof structural plate. Prevent the hollowing and cracking of the leveling layer from causing damage to the waterproof layer. The waterproof layer is given priority to with waterproof coating, and it can also be combined with the membrane. The roof drainage and the draining layer drainage are guaranteed to be independent of each other through automatic closing valves without mutual influence. The fine stone concrete layer requires waterproof concrete, and the roof finish layer acts as a rigid waterproof system for the roof waterproof system.

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...
