Problems solved by technology

Among them, the thermal insulation performance of building envelopes such as exterior walls is the key to the energy saving of the entire building. At present, most of the exterior wall insulation materials used in the market are often materials with low density and poor strength. The safety of the bricks pasted on the outside of the thermal insulation system cannot but arouse people's concerns
Moreover, in the process of use, it often causes hollowing and falling off of the external wall insulation and exterior facing bricks.

Embodiment 1

[0026] refer to figure 1 , a new type of building energy-saving wall, from the outside to the inside are the base layer 1, the insulation layer 2, the plastering layer 3, and the finish layer 4, the base layer 1 and the insulation layer 2 are connected by an adhesive, so A reinforced mesh cloth 5 is provided between the plastering layer 3 and the facing layer 4, and the thermal insulation material of the thermal insulation layer 2 includes crop straws, adhesives, waterproofing agents, preservatives, and flame retardants. The adhesive is isocyanate resin, the waterproofing agent is paraffin wax emulsion; the preservative is borate powder; the flame retardant is magnesium hydroxide.

Embodiment 2

[0027] Embodiment 2 The construction method of the new building energy-saving wall body

[0028] Such as figure 2 As shown, a new type of building energy-saving wall and its construction method, including the following steps:

[0029] Step 1. Apply adhesive on the base layer and paste the insulation material to form the insulation layer;

[0030] Step 2. Add a layer of plastering layer on the insulation layer, and lay glass reinforced mesh cloth on the plastering layer;

[0031] Step 3. Make a finishing layer on the reinforced mesh cloth, and the finishing layer adopts paint and facing bricks.

[0032] Such as figure 1 Shown, the preparation method of the thermal insulation material of described thermal insulation layer is:

[0033] Step 1: Clean and remove weeds: prevent the mixed weeds from easily rotting in a humid environment, which will affect the quality of straw bricks;

[0034] Step 2: cutting: cutting the cleaned straw with a cutting machine to obtain straw fibe...

Embodiment 3

[0040] The performance test of embodiment 3 energy-saving wall body

[0041] The fire protection grade of the material can reach F90, the shrinkage rate is generally 0.02mm / m, the sound insulation is 50dB, and the thermal conductivity is ≤0.05W·(mk) -1 , Compared with brick walls, it can reduce the weight by 75-80%, and reduce the cost by 30%.

Abstract

The invention discloses a novel energy-saving construction wall body and a construction method thereof. The energy-saving wall body sequentially comprises a base layer, a heat insulating layer, a floated layer and a finish layer from the outside to the inside; the base layer is connected with the heat insulating layer through adhesion agents; a strengthening net cloth is installed between the floated layer and the finish layer; and thermal insulation materials of the insulating layer comprise crop stews, adhesion agents, water proof agents, corrosion proof agents and fire retardants. The invention further provides the construction method of the novel energy-saving construction wall body. The novel energy-saving construction wall body has the characteristics that hollowing and falling off are not prone to happening, and service life is long; the novel energy-saving construction wall body is suitable to be promoted and applied.

Description

technical field [0001] The invention belongs to the technical field of building structure construction, and in particular relates to a novel building energy-saving wall and a construction method thereof. Background technique [0002] The large proportion of high-energy-consuming buildings exacerbates the energy crisis. Until the end of 2002, my country's energy-saving building area was only 230 million square meters. More than 40 billion square meters of houses have been built in my country, which are high-energy-consuming buildings. The total amount is huge, and there is a huge potential energy crisis. As the relevant person in charge of the Ministry of Construction pointed out, only by the end of 2000, the annual consumption of commodity energy in my country’s buildings totaled 376 million tons of standard coal, accounting for 27.6% of the total terminal energy consumption of the whole society, and the increase in building energy consumption has a negative impact on the co...
