Abstract

The invention discloses a construction method for a green roof system. The construction method comprises the following steps that step 1, a leveling layer is constructed on a roof basic layer; step 2,a rigid water-proof slope layer is constructed; step 3, an intercepting drain is built; step 4, a secondary drainage and steam exhaust network is laid; step 5, a heat insulating layer is laid; and step 6, green planting is conducted. According to the construction method for the green roof system, rigidity and water resistance are achieved, drainage is arranged to be principal, and vegetation maintenance is achieved. Through the secondary drainage and steam exhaust network arranged in the roof heat insulating layer, damage to the roof due to excessive steam pressure caused by sun blazing in the heat insulating layer is eliminated, vertical steam passing is achieved, and water drainage and steam exhaust are achieved.

Description

1. Technical field [0001] The invention relates to the technical field of building roof construction, in particular to a construction method of a green roof system. 2. Background technology [0002] Traditional membrane waterproof flat roofs tend to accumulate moisture in the insulation layer during construction and use, forming condensed water; when exposed to the sun, it will cause a huge partial pressure of steam, which will cause the membrane to curl upwards. At the same time, the huge temperature stress can cause oblique or horizontal cracks in the surrounding parapets. Once this happens, not only will it rain and leak, but it will also be abnormal when the weather is sunny. In addition, the reinforced concrete structural slab on the roof is greatly affected by the external environment, such as sun, rain, and freezing. Since concrete is a hydraulic material, it is easy to cause cracks and reduce the service life due to lack of water, drying and improper maintenance du...
