Description

Water accumulation preventing drainage guide structure in roof

Technical Field

The utility model relates to a civil engineering roofing waterproof technical field relates to a roofing is inside prevents ponding drainage guide structure.

Background

Because roof reinforced concrete floor self has the defect of shrinkage cracking, in order to improve roof waterproof performance, additional flexible waterproof layer often adopts at present, and roofing drainage system water inlet often sets up in flexible waterproof layer surface, requires theoretically that any seepage phenomenon can not appear in the flexible waterproof layer. The floor concrete of the roof structure in the design form has no waterproof performance practically. The roof flexible waterproof system is very fragile, and the quality is severely restricted by construction environment, climate, material quality and construction process. For example, in the south of China, high temperature and rain exist in summer, in the north of China, low temperature and snow exist in winter, the detailed structures such as lap joint and edge folding of the waterproof material can be repeatedly expanded and contracted to generate stress, and the waterproof material is easy to age. Different settlement changes can be generated after the building is finished, and stress can be generated in different internal areas, so that the flexible waterproof effect is not good. The construction links are operated manually, the objective quality influencing factors are more, and the construction quality is difficult to ensure. The blind pursuit of low cost and high benefit results in different market material links, different prices in the same brand and the market, and the material performance is not guaranteed at all. Moreover, later-period proprietors can build facilities against regulations on roofs and destroy waterproof layers and the like due to improper use. These disadvantages all contribute to quality problems of the flexible waterproof facing. If the flexible waterproof layer is damaged, even if a tiny crack gap or leakage point is locally formed, due to gradual infiltration of rainwater, steam pressure is generated inside the flexible waterproof layer, the pressure of the internal steam is gradually increased along with the increase of water inflow and the change of outdoor temperature, more flexible interfaces can be directly damaged, a water inlet channel is enlarged, the flexible waterproof layer can permeate into the room in the opposite direction, the phenomena of moisture regain, mildew, leakage and the like are locally formed inside the room, even the whole roof waterproof system is seriously crashed, and the service life of the waterproof system is seriously shortened.

Therefore, the development of a structure capable of further improving the drainage performance inside the roof and reducing the waterproof pressure of the flexible waterproof layer has practical significance.
