Problems solved by technology

[0003] However, this method is only compounded by surface contact
The function of this insulation structure is only passive insulation, which is greatly affected by temperature changes.
Due to seasonal changes, or the temperature difference between day and night in the same season, the interface between the protective layer and the thermal insulation layer frequently expands and shrinks, causing the protective layer to crack easily
At the same time, due to the change of temperature difference, the wall is easy to condense, the insulation layer is damp and the performance is reduced, and the thermal insulation effect is not ideal.

Embodiment 1

[0076] Embodiment 1: the preparation of test piece

[0077] Prepare the test piece according to the following steps:

[0078] (1) Fix the light steel keel on the base wall (5cm thick) with expansion bolts, and the distance between the keels is 50cm;

[0079] (2) Fill the glass wool insulation layer between the keels (bulk density> 16kg / m 3 , thickness 5cm);

[0080] (3) Tyvek Waterproof and vapor permeable membrane (model 1060B, for ordinary special guard No reflective layer) spread on the insulation layer and the keel according to the ups and downs of the keel, and fix the glass wool and waterproof and vapor-permeable membrane on the foundation wall with rock wool nails;

[0081] (4) Lay galvanized ribbed expansion mesh on the waterproof vapor permeable membrane and the keel; and

[0082] (5) Plastering on the galvanized expanded mesh with ribs.

[0083] After drying, the test piece was obtained. For the plan view of the specimen structure and the light steel keel, s...

Embodiment 2

[0087] Embodiment 2: the detection of test piece

[0088] 2.1 Detection steps and basis

[0089] exist Figure 7 Temperature sensors are installed on positions No. 7, 8 and 9 shown in A, and the thermal resistance value R of different interlayers is calculated by measuring the temperature of different layers.

[0090] Among them, the thermal resistance R of a single material layer is calculated by the following formula :

[0091] R=δ / λ(M 2 K / W)

[0092] The thermal resistance R of the multilayer homogeneous material layer structure is given by the following formula

[0093] R=R1+R2+......+Rn=δ1 / λ1+δ2 / λ2+......+δn / λn

[0094] The heat transfer resistance Ro(M 2 ·K / W)

[0095] Ro=Ri+∑R+Re=∑R+0.15 (0.16 in winter and summer)

[0096] In the formula: R, R1, R2, Rn-the thermal resistance of each material layer (M 2 K / W);

[0097] Re- heat transfer resistance of outer surface of enclosure structure, Re=0.04 (winter) or Re=0.05 (summer);

[0098] λ, λ1, λ2, λn-the therma...

Abstract

The invention relates to a heat preservation and heat insulation system for the outside wall or roofing of a building. A gap is formed between a water barrier and an outside vertical face layer of the system, which is convenient for air to flow and has good effects of heat preservation and heat insulation. The invention further relates to a method for ensuring that the building has effects of heat preservation and heat insulation by adopting the heat insulation system.

Description

technical field [0001] The present invention relates to the field of construction. In particular, the invention relates to a system for use on building facades and / or roofs, and a method of providing the system on building facades and / or roofs. Background technique [0002] As people pay more and more attention to energy consumption, energy-saving buildings are getting more and more attention. Usually people realize heat preservation and heat insulation through the body of wall or roof that has protective layer and insulation layer structure. For example, figure 1 A shows a commonly used thermal insulation / insulation system, from inside to outside, reinforced concrete or blocks, expanded polystyrene board or extruded polystyrene board, glass fiber mesh and plaster or other building facades. figure 1 B shows another common thermal insulation / insulation system, from inside to outside, reinforced concrete or blocks, rubber powder polystyrene particles, fiberglass mesh and pl...
