Problems solved by technology

This system has two disadvantages: first, it can only provide ventilation and heat insulation in summer, but not in winter; second, the system has a large self-weight, and many old houses were not designed with this load in mind. As a result, many houses cannot be used.

Embodiment 1

[0037] Such as Figure 1-2 As shown, the present invention discloses a roof heat insulation and heat preservation system. The system is provided with a plurality of legs 2 above the roof waterproof felt, and each group of four legs forms a rectangular combination (a square is a special case of a rectangle, which is used here Rectangle, including both square and rectangle, refers to a larger range.), add a piece of fiber cement board 1 above each rectangular leg combination, that is, below the four corner points of each fiber cement board Four outriggers are set, and multiple fiber cement boards are spliced ​​together to form a thermal insulation roof system, and the joints between adjacent fiber cement boards are sealed with sealing tape. Fiber cement board has the advantages of not easy to deform, not easy to warp and light weight, it is very suitable for heat insulation and sun protection layer of the roof. In order to reduce the load of the roof, the outriggers are made of...

Embodiment 2

[0040] Regardless of winter heating (such as in southern China), the following measures can be taken:

[0041] 1. Remove the windshield;

[0042] 2. Remove the heat absorbing layer (black paint) of the fiber cement board and windshield;

[0043] 3. Remove the sealing tape, and only keep the reflective layer (white or silver coating) of the fiber cement board;

[0044] 4. The height of the legs is slightly higher than that of Embodiment 1.

Embodiment 3

[0046] Such as image 3 As shown, in order to reduce the load-bearing of the roof, the outriggers are made of foam plastic, so that the roof outriggers have the characteristics of light weight, heat insulation, sound absorption, and shock absorption. In order to achieve the purpose of waterproofing and fire prevention, a layer of inorganic coating is provided on the outside of the foam plastic.

Abstract

The invention provides a roof heat insulation system. The roof heat insulation system comprises a plurality of supporting legs, wherein the plurality of supporting legs are evenly distributed on a roof, a plurality of fiber cement boards are placed on the supporting legs, a wind shield is detachably arranged on the periphery of the system, one side of each of the fiber cement boards and the wind shield is coated with a reflective heat insulation coating, and the other side of each of the fiber cement boards and the wind shield is coated with a heat absorption heat insulation coating. The system has the advantages of light weight, high modularization degree, convenience in construction and installation and the like.

Description

technical field [0001] The invention relates to the field of construction, in particular to a roof thermal insulation system. Background technique [0002] Now, the country's new housing reform policy is to no longer build high-rise buildings, and no longer demolish large-scale construction, but to renovate and repair existing old houses to improve people's living comfort. Most of the old houses were more than 20 years old. At that time, the design code had lower requirements on the insulation performance of the house. The rooms on the top floor were cold in winter and hot in summer. In summer, the air conditioner was fully turned on and the heating was turned on in winter, which was a great waste of energy. [0003] In the southern region of my country and some northern regions, there is also the practice of setting an air barrier on the roof. For example, use cement concrete to make a small bench form and put it on the roof to facilitate sunshade and ventilation in summer...
