The roof refers to the surface of the roof of a building, and also refers to the part between the ridge and eaves. This part occupies a larger area of ??the roof, or the roof is the larger part of the roof. Generally, it includes cast-in-place concrete floor, cement mortar leveling layer, thermal insulation layer, waterproof layer, cement mortar protective layer, drainage system, parapet and lightning protection measures, etc. In special projects, there is also the construction of tile surface (tile hanging strips) .
It is the surface of the roof, not the roof. Substrate layer This layer is a mixed substrate layer, which is made of screened lightweight materials to reduce the load-bearing capacity of the roof. The volume ratio of each substrate is: peat soil: vermiculite: perlite: sawdust = 4:3:2:1 , then mix each matrix evenly, and the thickness of the mixed matrix layer is 15cm.
Extended information
Roofing engineering is one of the main parts of the housing construction project. It includes both the materials and equipment used in the project and the design, construction, maintenance and other technical activities carried out; It also refers to the object of engineering construction, which plays a functional guarantee role.
In addition to safely withstanding various loads, roofing projects also need to have the ability to withstand temperature, wind, rain, ice and snow, and even earthquake damage, as well as withstand deformation caused by temperature differences and expansion, contraction, and cracking of the base structure. . The slope of the roof is mainly determined by factors such as usage needs and local weather.
