Description

Lightweight Roofing System

technical field

The utility model relates to the technical field of buildings, in particular to a light-duty roof system, which is suitable for regions with hot summer and warm winter and regions with hot summer and cold winter.

Background technique

China currently has the largest construction market in the world. However, with the rapid development of the construction industry, the problems of building resource consumption and energy consumption have become increasingly prominent, and the situation of building energy conservation is quite severe. Facing the disadvantages exposed by traditional materials and technologies in terms of building energy conservation, safety and environmental protection, seeking new materials, new technologies and application systems has become an important aspect of building energy conservation research.

In hot summer and warm winter regions, the main function of the roof system in the building maintenance structure is waterproof and heat insulation, and winter insulation is generally not considered. In order to meet the roof waterproof and thermal design requirements in hot summer and warm winter regions, the traditional method of roof system construction is based on the "Central South Region Engineering and Construction Standard Design Building Atlas", as shown in Figure 1, which is the existing technology "Central South Region Schematic diagram of the superior roof system structure of "Method ④" in the second-level waterproofing of the Engineering Building Standard Design Architectural Atlas (11ZJ201), in which, 1 is ceramic floor tiles and the base layer, and 2 is the dry-laid non-woven polyester fiber cloth isolation layer, 3 is 1.2 thick synthetic polymer waterproof membrane, 4 is 1.5 thick synthetic polymer waterproof coating, 5 is brushing base treatment agent once, 6 is 20 thick 1:2.5 cement mortar leveling layer, 7 is 20 thick (thinnest part) 1:8 cement aerated concrete slag to find 2% slope, 8 is the insulation layer, 9 is the air barrier layer of 1.5 thick polyurethane waterproof coating, along the wall 150 higher than the upper surface of the insulation layer, 10 is 20 thick 1:2.5 cement mortar leveling Layer 11 is the reinforced concrete layer, and the surface is cleaned: the architectural design uses 1 to 3 waterproof layers and a certain thickness of low thermal conductivity insulation materials according to the waterproof level to meet the roof waterproof function and the heat transfer coefficient (k) limit of the enclosure structure . In order to achieve the above waterproof and thermal design requirements, multiple layers of leveling layers, protective layers, vapor barrier layers and other structures are added, so that the roof system generally has 6 to 10 layers, the average thickness is 150±50mm, and the average roof load is 100 ±20㎏/㎡.

Moreover, in areas with hot summer and warm winter, the solar heat radiation is strong and the sunshine time is long. In the traditional roofing method of the prior art, the outermost protective layer or decorative layer generally adopts cement mortar, concrete or ceramic tiles that reflect weakly to solar heat radiation. In hot summer and warm winter regions, after the roof system is heated by solar heat radiation during the day, the highest temperature on the roof surface can reach nearly 60°C, and the indoor temperature can reach up to 40°C, resulting in a poor indoor thermal environment for living. Solar radiation heat energy is not only transmitted to the room during the day, but also continues to be transmitted to the room at night due to the heat storage on the roof, which increases the energy consumption of air conditioning and cooling. In addition, building roof heat storage is also an important factor causing the urban heat island effect.

Since the traditional roofing method is a multi-layer superimposed structure, the building load is increased, and the building roof heat storage of the traditional roofing in the prior art is also an important factor causing the urban heat conduction effect.
