Description

The external wall system of tool insulation construction

Technical field

The utility model relates to a kind of external wall system of tool insulation construction.

Background technology

At present, China is only second to the U.S. second largest energy consumption state in the world, it is also maximum in the world construction market, the building energy consumption of China has accounted for 30% of whole society's total energy consumption, and the construction wall energy consumption accounts for 60～70% of building energy consumption, the construction wall power-saving technology in world's power-saving technology in occupation of critical role.

High strength, high-durability rock wool are called rock (ore deposit) cotton or stone is cotton.It is to process through special process as primary raw material take high-quality basalt, diabase etc., and its mechanical property and endurance quality all are better than the external wall outer insulation material of general existing use.Because it is inorganic material, rock wool is known as A level incombustible material by countries in the world, and is widely used again.

The heavy finish material, as: exterior wall loam brick, exterior wall all-body tile, exterior wall ceramic splitting brick, imitative stone face brick, mosaic brick etc., its quality is closely knit, wear-resisting, has water-fast, freeze proof, abrasion resistance.Sturdy and durable, bright in luster, fire prevention, waterproof is wear-resisting low with maintenance cost.Impact resistance intensity is high, is subject to collide the zone therefore be specially adapted to foundation position, the first floor or building access etc.Easily clean after staiing simultaneously, wall face is kept clean, and can prevent that building surface is by atmospheric corrosion.Therefore the heavy finish material is traditional external wall decorative materials of a lot of countries in the world.

Compare with the coating ornamental surface material, there is following safety issue in the heavy finish material as the external wall heat insulation system of finish coat:

1) deadweight.Because the deadweight of the external wall heat insulation system take coating as finish coat generally can not surpass 10kg/m2(EPS plate and protection, outer finishing coat), and more than the external wall heat insulation system of heavy finish material deadweight can reach 50kg/m2,80kg/m2 even, for the 5-8 of coating system doubly.

2) warm and humid shear stress.Due to the rigidity of heavy finish material much larger than being coated with finish material, inconsistent with the desired flexibility of system protective facing, compare to and directly paste heavy finish material (just-just) on the rigidity metope, or compare to and be coated with facing external wall heat insulation system (gentle-gentle), the distortion of this flexible substrates-system that the rigid surface structure causes is larger, produce larger warm and humid shear stress between face brick and protective facing, affect the safety of adhering between face brick and protective facing.

3) freeze thawing problem.Compare with being coated with the facing external wall heat insulation system, glazed tile steam resistance is very large.Check the external insulation system that the ceramic tile peeling phenomenon is arranged, can find that ceramic tile always falls down together with cementing agent, finishing mucilage, and outside finish always is in full water state.The condensed water at the high water vapor resistance forms the ceramic tile back side compares to this system to be coated with the probability of facing external wall heat insulation system generation freeze-thaw damage larger.In addition, alkali part of ceramic tile bond, finishing mucilage (cement based) infringement to grid cloth after combining the moisture that gathers for a long time is also very strong, air-locked glazed tile has not only stoped the drying of material, and stoped and absorbed CO2 from air, make finishing mucilage aquation quickly, and grid cloth is stayed in harmful alkali for more time.

4) surface layer problem of Cracking claims again warm and humid tensile stress problem.The heavy finish material is the same with pasting on the metope of rigidity, and the cracking of heavy finish material external wall heat insulation system mainly occurs in the brickwork joint place, but the possibility of cracking is much larger than the former, and reason is that the warm and humid tensile stress of system is greater than the former.The method the most intuitively of check external insulation system Long-term Anti cracking behavior is the atmospheric exposure test in European standard ETAG0004.The evidence of external scientific research, testing agency, heavy finish material external insulation system is difficult to by this test, and the cracking of brickwork joint almost is difficult to avoid.

Therefore at present building trade generally believes that rock wool external insulating system for thinly plastered external wall outside cannot use heavy amount finish material.
