Description

Roof structure with waterproof and heat preservation functions of drainage

Technical Field

The utility model relates to a waterproof field of building roofing, specifically speaking relate to a roofing structure with waterproof and heat preservation function of drainage.

Background

The roof is the topmost part of the roof of the building, and the heat preservation and waterproof effects of the roof are very important. The existing house roof is generally poured by concrete to serve as a base layer, and a layer of cement mortar is paved on the surface of the base layer to serve as a protective layer. However, for such a roof structure, the waterproof and heat insulation effects are not sufficient, and mainly the effects are that the heat insulation effect is poor, the roof is exposed to sunlight for a long time, the roof concrete layer is easy to generate expansion gaps, and the traditional concrete has strong heat conductivity, which leads to the rise of indoor temperature. In addition, the roof often cracks when exposed to the sun and rain for a long time, and the waterproof performance and the heat preservation performance of the roof are greatly reduced when the surface of the roof cracks. Therefore, it is necessary to provide a roof waterproof measure having a good waterproof and heat insulating function for the roof of a building.

Preferably, the top of the parapet wall is also provided with an insulating cushion block.

The utility model has the advantages that:

1. the roof base layer is provided with the base mortar layer on the top, the main filler of the base mortar layer is cement and mortar with the particle size smaller than 1mm is matched as an auxiliary material, and meanwhile, the base mortar layer is provided with a certain proportion of adhesive and waterproof agent; as the last waterproof line, water is prevented from permeating into the roof base layer;

2. the anti-cracking net layer is laid outside the leveling layer, so that the anti-cracking net has good tensile resistance, the leveling layer is prevented from cracking, and the roof base layer is well protected;

3. the upper part of the anti-cracking net layer is provided with the heat-insulating layer, so that the heat-insulating effect of the roof is improved; the roof is prevented from cracking due to the rapid temperature change; the waterproof coil layer is laid on the heat insulation layer, so that the waterproof performance is further enhanced, and most of water is prevented from permeating into the roof base layer; the upper part of the waterproof roll layer is provided with the arc-shaped concrete protective layer, so that the waterproof roll layer is well protected from long-term exposure to the sun, the service life of the waterproof roll is prolonged, and the service life of the waterproof roll is prolonged; the upper part of the concrete protective layer is a permeable layer made of permeable concrete, and the permeable layer made of the material has better water permeability and better structural strength, plays roles of water permeability and earthquake resistance and can resist the impact of hailstones; and finally, a drain pipe is arranged on the lowest surface of the concrete protective layer, when the roof is too much in rain water accumulation, redundant water cannot penetrate through the permeable layer and is finally discharged through the drain pipe, and the water accumulation on the roof is avoided.
