2 optimizes design of style of palisade structure wall

2.The wall outside 1 is the main body part of palisade structure, structure of high-level architectural palisade is different from building of bricky stone structure, former it is ferroconcrete frame or structure of wall shears force bearing, accordingly, palisade structure belongs to stuff stuff, to reduce load, achieve heat preservation, adiabatic requirement, use light qualitative efficient insulation material, in cold region at present commonly used wall system practice has: Shaly ceramists concrete is hollow block; Argillaceous air brick and sincere brick are compound wall body; Argillaceous sincere brick or with filling of cotton of air brick cliff are compound wall body. But existence question is more, energy-saving effect still the requirement of short of standard. The material of palisade structure is decorated especially side and inside, below the same climate condition of cold region, the heat preservation result that because material administrative levels arranges different place,obtains is endless also and same, to avoid condenser water of the generation inside wall body, heat-insulation layer sets outer side more appropriate some.

2.Body of wall of palisade of architectural of 2 high level shoulds not be the polystyrene bubble of heat preservation of the side outside using board (Shu Le board, PG board) , cliff cotton board wait for light qualitative insulation material. An architectural life is little criterion a few years, go up more hundred years, the application of material and the life that build whole should synchronous. To what pledge gently outside heat preservation is compound wall body, the author thinks to put in the place that is not worth below:

(1) aseismatic ability is poor, yi Song comes loose, as bad as union of structural component part, integral performance is poor.

(2) cannot bear exterior decorate stick, hang load, be like: Stick stone material, installation decorates component part to wait.

(3) cannot bear have oscillatory authentic, planing machine decorate, be like: Chop axinite facing, grant to accept hole, slot easy occurrence Leng Qiao.

(4) wall surface is easy occurrence crackle. Besides, compound wall body because those who cut force fence is frame Liang La, built-in, wall form content is easy cause Leng Qiao, it is heat preservation, adiabatic weak point. According to determining, the Leng Qiao that high-level building appears occupies 13 % of ～ of 5 % of whole hot losing about, because this should cause an architect to take seriously, adopt significant tectonic step to avoid to produce Leng Qiao as far as possible.

2.General promotion of 3 abroad uses concrete hollow block is used at the high level to build palisade structure heat preservation, europe, beautiful each country gains many advanced experience. Be like: Heat insolation of the TB that the United States develops heat preservation is compound block; Block of polish occlusive type heat preservation, two combination become system of 320 large walls, efficient insulation material is written inside hollow block, wall body conducts heat 1100W/ M2 K of ～ of coefficient K= 01209; A kind of of Finnish development hollow block, fill between space get together amine fat insulation material, 300 thick, conduct heat coefficient K= 0. 25 ～ 0. 28W/ M2 K. The concrete that the construction that 50 % of certain and Euramerican country controls already used a variety of forms is hollow block. Because concrete is hollow effect of block heat preservation is good, have particular strength again, prevented a few corrupt practice of body of wall of light qualitative composite material.
