Problems solved by technology

[0005] Because 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

Embodiment 1

[0093] Dalong Villa on Xike Road, Haikou was refurbished and rebuilt in March 2014. The structure diagram of the villa is shown in image 3 . The villa has 4 floors, and the area of ​​the 4th floor is about half of that of the 3rd floor. The terrace of the room on the 4th floor is the roof of the 3rd floor, and the roofing method on the floor tile protection layer of the "Central South Region Engineering Construction Standard Design Architectural Atlas" is adopted, and the light roof system provided by the present invention is arranged on the 4th floor roof.

[0094] The specific method of roofing on the third floor is as follows: set a 20mm thick (thinnest) 1:8 cement hydrophobic expanded perlite on the reinforced concrete roof slab to find a 2% slope, and a 20mm 1:2.5 cement mortar Leveling, 1 layer of 1.5mm waterproof coating, 1 layer of 1.2mm polymer waterproof membrane, a full layer of 0.3mm thick polyethylene film, 25mm thick 1:4 dry hard cement mortar, 8mm-10mm floor ...

Embodiment 2

[0100] A three-story self-built house in Danzhou, Hainan. The original roof was made of cast-in-place concrete slabs, and the roof was not waterproofed. The roof surface was leveled and sloped with a layer of 1:2.5 cement mortar with an average thickness of 20mm. After 2 years of use, the roof cement mortar cracked severely in many places, resulting in serious roof leakage. In summer, the solar radiation is strong, the highest temperature on the roof is above 52°C, and the indoor ceiling temperature of the downstairs house can reach as high as 45°C. Due to the severe radiant heat from the ceiling, the thermal comfort of the indoor environment is still poor even if the air conditioner is installed indoors. Generally, the air conditioner will not be effective until the ceiling cools down after 12 o'clock every night.

[0101] In August 2013, the self-built house adopts the light-duty roof system provided by the present invention: clean up the original slope-leveling layer; apply...

Abstract

The invention provides a light roof system suitable for regions hot in summer and warm in winter and regions hot in summer and cold in winter. The light roof system comprises a sloping layer and / or a leveling layer, an interface agent coating arranged outside the sloping layer and / or the leveling layer, a waterproof layer arranged outside the interface agent coating and a heat insulation coating arranged outside the waterproof layer, wherein the waterproof layer is a waterproof roll layer and / or a waterproof coating. According to the light roof system, the sloping layer and / or the leveling layer are / is arranged on a cast-in-place concrete roof floor slab base layer so that the interface agent coating, the waterproof layer and the heat insulation coating can be laid successfully later. The light roof system greatly reduces building loads, lowers the construction cost and is high in building safety; the energy saving effect is obvious when the light roof system is used in the regions hot in summer and warm in winter; due to the fact that heat accumulation of the roof system is lowered, the urban heat island effect is relieved obviously, and the environmental comfort level of the indoor temperature of a building is increased; a roof is resistant to water, not prone to leakage and easy and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a light-duty roof system suitable for regions with hot summer and warm winter and regions with hot summer and cold winter. Background technique [0002] 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. [0003] In hot summer and warm winter regions, the main function of the roof system in the building maintenance structure is waterproof and h...
