Assembly type roof drainage system and construction method

Abstract

The invention belongs to the field of roof water prevention and particularly relates to an assembly type roof drainage system and a construction method. The assembly type roof drainage system comprises a drainage assembly and a waterproof layer, wherein the drainage assembly and a roof are arranged together, and the waterproof layer and drainage pipes are arranged together. The waterproof layer comprises an impermeable layer arranged on the roof. The impermeable layer is sequentially provided with a coiled material waterproof layer, a heat preservation layer and a liner waterproof layer. The drainage assembly comprises an upper drainage pipe provided with an upper water inlet and a lower drainage pipe arranged on the periphery of the upper drainage pipe. A gap is reserved between the upper drainage pipe and the lower drainage pipe and forms a lower water inlet. The upper water inlet and the liner waterproof layer are arranged together, and the lower water inlet and the coiled material waterproof layer are arranged together.

Description

technical field [0001] The invention belongs to the field of roof waterproofing, in particular to an assembled roof drainage system and a construction method. Background technique [0002] The roof is the most important enclosure system of a building, and it is also the most severely eroded part of the building by natural factors (wind, snow, rain, temperature changes). Relevant architectural survey data at home and abroad show that flat roofs have always had common and frequent water leakage problems. Leakage not only affects the use of building functions, but more seriously shortens the service life of the roof. According to the investigation of relevant departments, domestic flat houses The average lifespan of noodles is less than 8 years. [0003] This has proved that there is a certain fatal deficiency in the current roof construction technology in a scientific sense. However, in solving this problem, we have been trying to persistently seek a good waterproof material...

AI Technical Summary

Problems solved by technology

[0007] The structure of the conventional roof system is unscientific. The waterproof layer is installed on the unstable leveling layer (base layer) and is prone to structural damage. The crack reflection causes the waterproof layer to be damaged due to uneven stress and strain.

The waterproof layer is damaged, and the leaking water accumulates and spreads in the structural layer, causing a large area of ​​leaking water, and the leaking point is not easy to determine. Once the leaking water problem occurs, it is difficult to repair

The roof is directly exposed to the natural environment, and is seriously affected by the change of environmental temperature. The accumulated water in the structural layer will cause chain drum failure at high temperature. As the temperature changes, it will cause a vicious cycle of damage, which will eventually lead to a serious shortening of the life of the roof system.

[0008] The unreasonable structure of the conventional roof has caused serious water leakage problems. In order to achieve the service life of the building roof, it is necessary to repair or update the roof

The maintenance and demolition of the structural layer will produce a large amount of construction waste. The degree of classification and collection of construction waste is not high, and most of them can only be collected in a mixed manner. The recycling rate is low. Construction waste has a wide range of erosion on our living environment; If construction waste is piled up in the city, it will be unfavorable to the urban environment and aesthetics; there may be some safety hazards in the piling of construction waste, and some accidents may occur at any time; if the construction waste is disposed of directly in landfill, it will occupy land pollute the environment

No matter what kind of roof structure layer treatment method can not meet the concept of environmental protection, energy saving, cost-effective and high-efficiency
