Description
Technical field
The present invention relates to a kind of decoration type composite thermal-insulating wall and its construction method, belong to wall inclination field.
Background technology
The total amount that building energy consumption accounts for 1/3 China's building energy consumption of social total energy consumption rises year by year, in energy aggregate consumption
In shared ratio from the 10% of last century late nineteen seventies, rise to 27.45%.And the building energy consumption of developed country in the world
Typically constitute from 33% or so of national total energy consumption.Inferred with this, the research of science and technology department of Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD) shows, with urbanization process
Accelerate the improvement with people's living standard, China's architectural energy consumption ratio finally will also rise to 35% or so.So huge ratio
Weight, architectural energy consumption has become the weakness of China's economic development.
China's built house has more than 40,000,000,000 square metres to belong to highly energy-consuming building, and total amount is huge, huge energy danger of hiding
Machine.Because highly energy-consuming building ratio is big, annual just many 18,000,000 tons of the standard coals of consumption in single northern heating area, direct economic loss is up to 70
Hundred million yuan, 520,000 tons of multiple rows of carbon dioxide.According to analysis, China is in and builds the ancient cooking vessel most productive period, and the floor space for building up every year is up to 1,600,000,000
To 2,000,000,000 square metres, the summation of construction area is built up year more than all developed countries, and 97% above is high energy consumption is built.Therefore,
If not starting to focus on energy-saving design in construction, will directly aggravate energy crisis.
The enforcement period of the ninth five-year plan, Novel wall body heat insulation material enters Rapid development stage, has been in currently large-scale development；2001
Year, country further increases superseded traditional material, promotes the dynamics of Novel wall body heat insulation material, and promoted extension is to small city

Building block, aerated-block, gypsum hollow block, aerating flyash brick, porous clay brick, GRC wallboards, reinforcing fiber cement plate, folder
Core plate, fly ash aerated wallboard and composite thermo-insulating wall board, it may be said that species is various.But block and plate are only for the market share
There is dividing for size, whom who eats；It is each has something to recommend him for properties of product；But combined wall is abroad shared by developed country
Ratio occupies high.
201410051631.6 disclose a kind of decorative heat preservation composite wall and preparation method thereof, wherein, the preparation method
For：The first metal joist is fixed on the body construction；The first inorganic board and second are respectively provided with the both sides of the first metal joist
Inorganic board；Many screw rods are sequentially passed through and are fixed on the first inorganic board, the first metal joist and the second inorganic board, wherein, position
Screw rod at agent structure is sequentially passed through and is fixed on the first inorganic board, the first metal joist and agent structure；Insulation is starched
Material is injected into the space between the first inorganic board and the second inorganic board；Decorative plate of outer wall is installed, will be dry on decorative plate of outer wall
Suspension member is fixed on the outside of the first inorganic board, and gap is provided between decorative plate of outer wall and the first inorganic board.But its complex structure,
Building cost can be caused significantly to rise in work progress.
