The wall body 101 is the main structure of the thermal insulation wall, and the inner layer 102 is the structural layer inside the wall body 101 . In this embodiment, the inner layer 102 includes a first heat insulation layer 201 and a second heat insulation layer 202 connected together, and the first heat insulation layer 201 and the second heat insulation layer 202 play a role of heat preservation.

In the present embodiment, the connecting strip 203 is separated from the first insulating layer 201 and the second insulating layer 202, and the connecting strip 203 is used to connect the first insulating layer 201 and the second insulating layer 202. There is a gap between the connecting strips 203, so that There are gaps between the inner layers 102, and the isolation of the space is beneficial to block heat convection and achieve a better heat preservation effect.

The construction is convenient and fast, the construction efficiency is high, the insulation effect is good, and it has high strength. wide.

The concrete layer 302 plays a main supporting role. In this embodiment, the concrete layer 302 includes a plurality of air bubbles 303 inside, and the plurality of air bubbles 303 are distributed at intervals.

This concrete is air-entrained concrete. Inorganic thermal insulation materials such as air-entrained concrete are used in building energy conservation. Inorganic thermal insulation materials can withstand sunlight and have high operating temperatures. They are good non-combustible thermal insulation materials. However, in the application of air-entrained concrete, there are quality problems such as cracking of the wall and hollowing of the plastering layer, which seriously affect the appearance quality and use function of the building. The maintenance time is usually only about 5 days before being directly transported to the construction site, resulting in increased shrinkage. On the other hand, the air-entrained concrete block has a small bulk density and a small thermal conductivity, and the thermal conductivity of the mortar is large. When the external temperature is high, the temperature changes between the mortar layer and the block layer are inconsistent, and the temperature of the mortar layer changes greatly. The temperature change is small. When the temperature difference between the two reaches a certain limit, the volume of the second layer will change due to thermal expansion. Once the tensile stress generated by the joint of the two reaches or exceeds the mortar bonding force, The mortar layer will gradually fall off.

According to the requirements of the strength of air-entrained concrete, try to add different volumes of vitrified microbeads. When the content of vitrified microbeads is different, the influence on the thermal conductivity and compressive strength of concrete is different. In addition, factors such as cement type, strength grade, aluminum powder content, water-cement ratio, and admixtures will affect the thermal conductivity, compressive strength, thermal insulation performance, and fire resistance of concrete.

Air-entrained concrete uses siliceous materials (sand, fly ash and silicon-containing tailings, etc.) The lightweight porous silicate products made by pre-curing, cutting, autoclaving, curing and other processes contain a large number of uniform and fine pores after gas generation. It is a new type of wall that realizes the best combination of resources, performance and cost. body material. Air-entrained concrete will dehydrate and crack when heated to 80-100°C, but it will not lose strength until heated to 700°C. At the same time, the unique structure of air-entrained concrete makes it have good sound absorption effect, which is better than dense concrete. Plate and metal plate, and good machinability, has broad application prospects. However, air-entrained concrete has common problems such as low strength, high thermal conductivity, high water absorption and large volume deformation.

Air-entrained concrete has been developed for decades. The research and application in foreign countries are earlier, and the technology is relatively mature. At present, countries in the world that have conducted in-depth research on air-entrained concrete mainly include Japan, the United States, and India. In order to improve the physical and mechanical properties of air-entrained concrete, Japanese building materials experts ultra-fine the raw materials to a fineness of 3000 mesh, and add some admixtures, fibers, etc., which can greatly improve the strength of the concrete. But this is not practical in domestic application. Scientific research experts in the United States have also modified air-entrained concrete by adding fibers, but it has little effect on improving thermal conductivity and fire resistance. The vitrified microbead is an acidic glassy lava mineral. After a special process, the surface is vitrified and closed, and it is a spherical fine-diameter particle. It has excellent heat insulation, fire prevention, and sound absorption properties, and is suitable for light filling in many fields. Aggregate and thermal insulation, fire protection, sound absorption, thermal insulation materials. In view of this reason, the topic of vitrified microbead aerated concrete is proposed on this basis. The theoretical research and experiment are the first at home and abroad. The vitrified microbeads are used in aerated concrete, and the relationship between the strength, fire resistance, thermal insulation performance and composition of vitrified microbeads aerated concrete is obtained by adding different amounts of vitrified microbeads.

The body of wall 101 using air-entrained concrete has at least the following advantages:

1. Light weight: the porosity reaches 70% to 85%, and the bulk density is generally 500 to 900kg/m3, which is 1/5 of ordinary concrete, 1/4 of clay brick, and 1/3 of hollow brick, which is similar to wood and can float in water. The self-weight of the building can be reduced, and the comprehensive cost of the building can be greatly reduced.

2. Fire prevention: Most of the main raw materials are inorganic materials, so they have good fire resistance and do not emit harmful gases in case of fire. The fire resistance is 650 degrees, which is a first-class refractory material. The fire resistance of the 90mm thick wall can reach 245 minutes, and the fire resistance of the 300mm thick wall can reach 520 minutes.

3. Sound insulation: Because of its unique porous structure, it has a certain sound absorption capacity. 10mm thick wall can reach 41 decibels.

4. Thermal insulation: Due to the large number of pores and micropores inside the material, it has good thermal insulation performance. The thermal conductivity is 0.11-0.16W/MK, which is 1/4-1/5 of clay bricks. Generally, the thermal insulation effect of a 20cm thick aerated concrete wall is equivalent to that of a 49cm thick ordinary solid clay brick wall.

5. Impermeability: Because the material is composed of many independent small pores, the water absorption and moisture conduction are slow, and the time required for the same volume to absorb water to saturation is 5 times that of clay bricks. When used in the bathroom, the tiles can be pasted directly after the wall surface is treated with an interface.

6. Earthquake resistance: For the same building structure, it is 2 earthquake resistance levels higher than clay bricks.

7. Environmental protection: There is no pollution in the process of manufacturing, transportation and use, it can protect cultivated land, save energy and reduce consumption, and is a green and environmentally friendly building material.

8. Durability: The strength of the material is stable. After one year of exposure to the atmosphere of the test piece, the strength increased by 25%, and it remained stable after ten years.

9. Fast: It has good machinability, can be sawed, planed, drilled, nailed, and can be bonded with appropriate bonding materials, creating favorable conditions for construction.

10. Economy: The comprehensive cost is lower than that of solid clay bricks by more than 5%, and the usable area can be increased, which greatly improves the utilization rate of the building area.
