Description

[0002] Since the top of the building is exposed to direct sunlight, in order to isolate the high temperature, the roof structure of the existing building is generally required to have the function of waterproofing and heat preservation. The traditional roof waterproofing and heat preservation construction process generally adopts the method of pasting SBS insulation board on the upper surface of the roof through mortar, and then laying cement mortar as the leveling layer on the upper surface of the SBS insulation layer, and then laying the SBS waterproof layer and protective layer on the leveling layer in order to achieve the effect of waterproofing and heat preservation.

[0003] Due to the infiltration of rainwater, rainwater is easy to accumulate in the insulation layer of the roof during use. It is difficult for the water vapor to dissipate effectively due to the shielding of the external structure, which not only causes the evaporation of water to be slow, but also the evaporation and expansion of water vapor under high temperature transpiration can easily cause cracks and damage to the roof insulation structure. In addition, since the accumulated water is difficult to discharge, long-term accumulation will corrode the insulation structure. In addition, in winter, the roof will cause cracking and damage to the roof insulation structure due to the freezing of water, which will reduce the service life of the roof insulation structure. For this reason, a drainage and exhaust structure of the roof insulation system is proposed. Utility Model Content
