Description

A kind of energy-saving heat-insulating wall
Technical field
The present invention relates to a kind of building energy conservation heat insulation body of wall.
Background technology
Test proves, it is effective that thin-coat plaster heat-preserving wall arranges fire barrier to intercept fire spread, but sacrifice layer scope is large: three layers ~ one deck.The quality of thin-coat plaster heat-preserving wall topping early China is extremely difficult to control, and the quality problems of Alkali-resisting fiberglass mesh fracture are at almost ubiquity, once the serious situation of catching fire there is Hong combustion, worked hardly in fire barrier.
And containing macromolecule adhesive in the topping of the thin-coat plaster heat-preserving wall of organic insulation material, topping is combustible inherently, this is the basic reason of thin-coat plaster heat-preserving wall fire hazard when adopting organic insulation material.
Inorganic heat insulation material burning-point lower and and when having air between thin-coat plaster topping; as installed the heat-preserving wall of rock wool thin-coat plaster, also burn when reaching the burning-point of rock wool, and thin-coat plaster topping durability is bad; after cracking, rock wool is under the degrading of wind and rain, will destroy very soon.
After China's body of wall big fire several times, Ministry of Public Security 65# literary composition forbidding organic insulation material in 2011, so a lot of investigation of materials personnel do inorganic heat insulation material research in the industry, but inorganic heat insulation material also has a lot of problem:
Producing rock wool process is high energy consumption, high pollution process, can not popularize in an all-round way, we can not building energy conservation, one side high energy consumption, high pollution, inorganic heat insulation material cost is high.
Foam cement has occurred for many years, the external heat insulating wall of organic insulation material catches fire, make foam cement intimately, but foam cement also has problems, as quality fluctuation scope is large, (coefficient of thermal conductivity is higher, coefficient of thermal conductivity fluctuation range is large, dimensional stability is difficult to control, freezing and thawing performance is difficult to control, in the future once the heat-preserving wall that goes wrong is by efflorescence etc.), Heavy Weight, once install insecure, fall down danger, now in external wall insulation project almost without foam cement.
And inorganic heat insulation material can not meet market demand, the supply of goods one, the Harbin City urban applications not enough of such as rock wool.After Ministry of Public Security 65# in 2011 literary composition is issued, the external wall outer insulation engineering overwhelming majority founded a capital in the whole nation is stopped work, the main or handy organic insulation material of last external wall outer insulation.
China is regulation at present, during highrise building organic insulation material, the combustibility of organic insulation material should reach nonflammable B1 level, and the provinces and cities even had specify, the flammability of all engineering heat insulating materials is all not less than B1 level, has raised the cost of body of wall energy-saving heat preserving engineering.
China just promulgates " the Fire Test method of External Thermal Insulation System " GB/T29416, and this standard was carried out from October 1st, 2013: GB/T29416 specifies that experimental rig is in indoor construction, does not just have wind in laboratory test.Wind-force is different along with insulation layer thickness difference on the impact of fire, and insulation layer is thinner, and wind-force size is less to influence of fire; Otherwise insulation thickness, when catching fire, combustible is many, and wind-force is greatly with regard to danger close.
The construction scope of highrise building is large, and top wind-force is about 2 times of bottom wind-force, and fitful wind increases again wind-force (specifies in " loading code for design of building structures " GB50009) more than 2 times.
Build the passive type energy saving house of pole low energy consumption, although adopt the EPS plate of coefficient of thermal conductivity 0.032w/m.k, EPS plate also needs 250 ~ 300mm thick.Because heat insulating material is thick, when catching fire, fuel is too many, and fire hazard is just very large, therefore thinks that highrise building can not build passive type energy saving house in the world, but China city build in a large number in major part build highrise building exactly.
The fireproof performance of the topping increasing heat insulating material is only had to be only the basic way solving external heat insulating wall fire savety.If but increasing protective layer thickness such as reaches 40 ~ 50mm, be almost infeasible in construction.
Applicant has applied for several external heat insulating wall patent, improve a lot than the fireproof performance of present thin-coat plaster external heat insulating wall, energy-saving heat preserving performance, but plaster in existence scene, wet trade is many, the problem that construction is inconvenient, still there is infeasible problem when requiring thicker of plastering, and still there is fire safety potential problem in construction, still need the expensive heat insulating material needing to be not less than B1 level by flammability in most engineering.
The fire safety in construction and installation should be solved, also will ensure fire safety in its use long-term simultaneously, and convenient construction, reduce cost, the present invention proposes a kind of energy-saving heat-insulating wall.
Summary of the invention
The object of the invention is to provide a kind of energy-saving heat-insulating wall, to solve the problem described in background technology.
One of a kind of energy-saving heat-insulating wall of the present invention, it comprises base course wall, precast heated board, crab-bolt;
Described precast heated board comprises insulation layer, topping, and at the side matcoveredn of insulation layer, insulation layer is connected with topping;
The insulation layer of described precast heated board is inorganic heat insulation material or organic insulation material, or is the composite heat-insulating layer of inorganic heat insulation material and organic insulation material, or is the mixed material of inorganic heat insulation material and organic insulation material;
Described topping is prefabricated panels topping; Or topping is the composite bed of prefabricated panels and plaster skin coat; Topping has and necessarily prevents fire spread performance;
Precast heated board and base course wall be connected with under type, select the 1st) plant connect or the 1st) with the 2nd) plants and is connected, or the 1st) and the 3rd) plant and be connected, or all to select:
1), by precast heated board be placed in base course wall side, or precast heated board is set in the side of the base course wall of cast-in-situ concrete, by crab-bolt through precast heated board, precast heated board and base course wall are fixed;
2), insulation layer inner surface is non-burnishing surface, and being formed between the insulation layer of precast heated board and the base course wall of cast-in-situ concrete is connected together constructs;
3), bond with cementitious materials between precast heated board and base course wall;
Connect between precast heated board, form a kind of assembled energy-saving heat-preserving wall installing precast heated board.
A kind of energy-saving heat-insulating wall two of the present invention, it comprises base course wall, insulation layer, prefabricated panels topping, crab-bolt; Described insulation layer is arranged on the side of base course wall; Prefabricated panels topping is positioned at the outside of insulation layer;
The insulation layer of described precast heated board is inorganic heat insulation material or organic insulation material, or is the composite heat-insulating layer of inorganic heat insulation material and organic insulation material, or is the mixed material of inorganic heat insulation material and organic insulation material;
Described topping is prefabricated panels topping; Or topping is the composite bed of prefabricated panels and plaster skin coat; Topping has and necessarily prevents fire spread performance;
Prefabricated panels topping is fixed on insulation layer and has following 2 kinds of methods, select the 1st kind install or select 2 kinds of installations simultaneously:
1), crab-bolt through prefabricated panels topping, insulation layer, prefabricated panels topping and insulation layer and base course wall are fixed;
2), bonding connection between prefabricated panels topping and insulation layer, or bonding connection adds non-burnishing surface and is connected together;
Form a kind of energy-saving heat-insulating wall installing prefabricated panels topping.
The difference of the present invention and public technology is:
1, embodiment of the present invention one directly fixes precast heated board by crab-bolt, the outside matcoveredn of precast heated board.
In outer wall heat insulating engineering; insulation layer is fixed very general by crab-bolt; such as fix insulation layer with plastic expanding nail; but public technology does not pass precast heated board by crab-bolt; the precast heated board of fixing side band matcoveredn, forms regulation or the case history of the assembling external heat insulating wall installing precast heated board.
The precast heated board insulation layer 15-3 of embodiment one is to be the composite heat-insulating layer of inorganic heat insulation material and organic insulation material, and see Figure 25, external insulation layer 15-3-1 is alumina silicate PLASTIC LAMINATED, and base insulating layer 15-3-2 is polymer thermal insulative material.
Above 2 neither prior art, neither be apparent, this has the following fact to be basis:
1), from Chinese outer wall heat insulating situation analysis
As aforementioned, inorganic heat insulation material can not extensive use, thinking will improve the fire resistance of organic insulation material routinely, make it bring up to the B1 level of nonflammable by the B2 level of flame retardant type, but fire retardant is expensive, causes heat insulating material price significantly to go up, building exterior wall heat preserving cost is significantly gone up, and the fire safety be helpless in building Long-Time Service, and a lot of fire retardant is dispersed in air gradually, has pollution to environment.
Present density 30kg/m 3b1 level difficulty combustion graphite EPS plate price more than 700 yuan/m 3, and B2 level flame retardant type EPS plate price about 320 yuan/m 3.But so-called difficult combustion is only that electric welding spark can not ignite, once breaking out of fire in building Long-Time Service, when reaching polyphenyl plate more than 500 degree burning-point, nonflammable B1 level EPS plate is the same with flame retardant type B2 level EPS plate to catch fire.Now towards the passive type energy saving house future development of pole low energy consumption, the whole nation has three place's passive type energy saving house pilot projects at present, wall heat transfer coefficient is only present Beijing, Harbin requires 25 ~ 30% of energy-saving wall thermal transmittance, requires that wall heat transfer coefficient is not more than 0.15w/m 2.k.When adopting the thin-coat plaster heat-preserving wall generally applied, thermal transmittance 0.15w/m 2.k body of wall needs polystyrene block EPS thickness 300mm, and cost reaches more than 200 yuan/m 2.
The present invention is not the insulation layer of naked of installation, but by the side compound up-protective layer of insulation layer, forms the precast heated board of side matcoveredn, penetrate installation by crab-bolt, forms the assembled heat insulation body of wall of the precast heated board installing side band matcoveredn.
Current China to such an extent as in world wide, promote thinking that assembled architecture installs only to be confined to assembling and major structure of construction and assembling to be installed whole construction wall (energy-saving heat-insulating wall or non-energy-saving heat-insulating wall) is installed, also do not expect in wall thermal insulation technology, to carry out assembling installation.
Topping of the present invention prevents fire spread performance obviously far away higher than the insulation layer of thin-coat plaster heat-preserving wall.
Cement fibrolite plate or calcium silicate board are inorganic material, and its coefficient of thermal conductivity, generally in 0.35w/m.k, when its thickness 8mm, 10mm, 12mm, is equivalent to the thermal resistance of cement mortar protective course thick 23mm, 29mm, 34mm respectively, therefore prevents fire spread performance good.No matter in precast heated board storeroom or after installing wall, even if a certain piece of precast heated board catches fire, flame is all difficult to spread, fire safety during construction.When adopting strand board topping, can take precautions against fire by wooden construction pertinent regulations.Therefore, make precast heated board with B2 level EPS plate and just can meet fire savety requirement in construction and installation, 300mm thick B2 level EPS plate can reduce cost 100 yuan/m 2more than.If embodiment one is apparent words, the combustibility just without requiring organic insulation material is increased to B1 level by B2 level, not only increases considerably cost, and is helpless to the fire savety in Long-Time Service, and situ wet operation is many, not easily ensures workmanship.
When insulation layer be inorganic heat insulation material as rock wool time, embodiment one also must improve the flameproof protection to rock wool.
Only from the fire safety improving the fireproof performance of heat insulating material and solve energy-saving heat-insulating wall be conventional thinking.
China has to widely apply thin-coat plaster heat-preserving wall in order to energy security, but other countries' application seldom, and at present only in the application of Northern Europe a few countries, but the construction scope in Northern Europe is much smaller, mostly only has hundreds of square meter, mutual distance; China 10000m 2the building of scale is Minor Construction, and building density is large, becomes the forest of fuel after building up.Thin-coat plaster heat-preserving wall directly threatens people's livelihood safety and defense strategy safety, once there is war, city will be sea of flame.
The patented technology that applicant has been announced; thin-coat plaster topping is become the thick topping of plastering doing to be hung by concrete hanging top or supporting, reinforcing bar, gauze wire cloth; the fire safety of external heat insulating wall in the Long-Time Service stage can be ensured; but be still helpless to construction stage fire safety; still with the B1 level organic insulation material of nonflammable, the cost of external heat insulating wall can not lower.And for improving the fireproof performance of heat-preserving wall, when needing topping very thick, manually plaster and thicken in very difficult scene, and increase building weight.But adopt the prefabricated panels topping of cement fibrolite plate, calcium silicate board, its density is little, coefficient of thermal conductivity is low, thermal resistance is large, lightweight.Embodiment one reaches following object simultaneously:
1) construction stage fire safety is met; 2) available B2 level heat insulating material, significantly reduces cost; 3) also can ensure the fire safety in Long-Time Service, and reduce scene and to plaster wet trade, accelerating construction progress, promotes Process of Housing Industrialization; 4) the present invention is easily by adjustment prefabricated panels protective layer thickness, kind, meets different fire protection requirements, does not relate to on-the-spot increase depth of plastering, easy construction.Calcium silicate board has 6 crystallizations water, and the performances such as other durability also can meet the demands, and recommend to select.
In China's Energy situation, environment situation so severe period; why nobody expects in exterior wall exterior insulation work; by the structure of embodiment one, precast heated board is installed; be formed with the assembling external heat insulating wall of external protection? this is because embodiment one is not that thinking solves external wall outer insulation Problems existing routinely, it is not apparent.
2), from world environments situation analysis:
The United Nations once issued report display in March, 2007, and the emission reduction effect that green building and building energy conservation are contained is greater than all greenhouse gas emissions required in Kyoto Protocol, is equivalent to three times of the predetermined CER of Kyoto Protocol.As can be seen here, building energy conservation is very important to minimizing greenhouse gas emission.
In spring in this year, the World Bank delivers report and warns: " unless taked more multirow to move to climate warming, otherwise global temperatures will rise four degrees Celsius again in the end of this century.The whole world is faced with that sea level rise, the danger of food shortages, extreme weather conditions, and this will make coastal cities and the poor in the face of catastrophic effect ".The World Bank on November 18th, 2012 issue report to claim, climate change is one of ultimate challenge of facing of global evolution, and be descendants's meter, various countries should undertake respective moral duty, minimizing greenhouse gas emission of conscientiously taking action.……
Although global energy situation, environment situation are so severe, in the world many countries still do not admit the current extensive application of China, be easy to the thin-coat plaster heat-preserving wall technology of catching fire, the such as state such as the U.S., Russia.Dangerous because not only to prevent fires at ordinary times, and occur once generation war or terrorist activity, the city of thin-coat plaster heat-preserving wall is just easy to catch fire everywhere, even becomes sea of flame, and people do not hide part, are in extremely passive, dangerous situation by making country.We see in Mideast Asian war, the war in Iraq, Afghan War, and they are non-energy saving buildings, not because war makes city become sea of flame.The topping of thin-coat plaster heat-preserving wall does not have the performance preventing fire spread, needs to arrange the fire barrier up to 300mm, but sacrifice layer scope too large (three layers ~ one deck).
Whole world existing building is non-energy saving building in a large number, and new building is also non-energy saving building, or the energy saving building that heat bridge is many, energy-saving heat preserving effect is bad, and this makes building energy consumption in world wide remain high.The situation of whole world building energy conservation greatly affects Global Emissions of Greenhouse Gas, the United Nations repeatedly holds a meeting to study and reduces greenhouse gas emission matters, countries in the world are often difficult to reach an agreement, why who can be unwilling to reduce discharging? applicant is thought, does is one of major reason caused by a lot of technical problem does not solve, otherwise how not to reduce discharging?
China's building energy conservation, wall reform are in progress the difficult fact for a long time, and the situation of global building energy conservation all illustrates that embodiment one is not that thinking solves wall thermal insulation technology Problems existing routinely, is not apparent.
China and even the whole world all think that wall technology relies on novel wall material to solve, but any material has its pluses and minuses, only a kind of material is relied on to make wall technology be difficult to have breakthrough progress, although so the Chinese government over two, 30 years for building energy conservation, wall reform drop into a large amount of nursery finance, building energy conservation, wall reform progress still difficult.
Only have with multi-subject knowledge, multiple material, play the advantage of different materials, avoid its shortcoming, different materials is combined, optimize the difficult point that wall structure just can capture wall thermal insulating power-saving technology, solve the problems of wall technology, instead of only rely on a certain novel wall material just can solve the problems of assembling wall technology.
2, embodiment of the present invention two, 13, also paste in the indoor of base course wall and prefabricated panels topping is installed, or paste the composite bed topping installing prefabricated panels and plaster skin coat, described topping, indoor protection layer are the prefabricated panels topping meeting some strength; Can increase substantially the antidetonation of energy-saving heat-insulating wall, wind loading rating, be that existing building technology is unexistent, neither be apparent.
The structure of embodiment two, 13 utilizes the prefabricated panels that has and utilizes the thermal insulating material had to have the feature of some strength; the stress performance of insulation layer and prefabricated panels topping is played in body of wall energy-saving heat preserving engineering; while carrying out body of wall energy-saving heat preserving engineering; also carried out earthquake-proof construction simultaneously; increase building aseismicity, wind resistance, improve buildingsafety.Need the engineering increasing building aseismicity, wind resistance safety, installation precast heated board 15 should be pasted by 100% area or close to the area of 100% area, and also adopt the structure of embodiment two, 13.
Fiber reinforced cement board (comprising cement fibrolite plate or calcium silicate board) occurs for many years, just as ornament materials, or uses as the surface layer of the partition wall of lightgage steel joist.Who would have thought cement fibrolite plate or calcium silicate board, and the heat insulating material had such as EPS plate may be used for increasing building aseismicity, wind resistance?
Such as the tensile strength of EPS plate is not less than 0.1Mpa, is equivalent to the tensile strength of bearing masonry, and has elasticity; Fiber reinforced cement board has suitable rupture strength.When it can be used as decorative panel to use at present, because prefabricated panels is thin, be easy to the destruction that fractures under external force, therefore have rupture strength requirement.Fiber reinforced cement board and other Material cladding stressed time also should meet the rule of concrete structure stress destruction, the concrete sloping section how calculating the composite component having heat insulating material (as EPS plate) and fiber reinforced cement board is destroyed, and also should be determined by test.
The technician of architectural discipline, materials specialty is ignorant of structure knowledge.The technician of structure discipline just utilizes existing structure theory to design, various ornament materials is not understood in depth, because think that this does not belong to this area of specialization, so nobody proposes the stress performance utilizing prefabricated panels for a long time, the structure of increase building aseismicity, wind resistance and design concept.
Although applicant is structure discipline technician, although applicant studies nearly 12 years of wall technology with full energy, and research wall technology needs to carry out interdiscipline, cross-cutting research: except building field, also relate to and understand chemical field, some knowledge of metallography.In building field, need the knowledge such as Building technology, architectural construction, building physics, building thermal technique, structure discipline, also need to know multiple building materials, just can broaden one's scope of mind, Appropriate application different materials, optimize wall structure.But the patent document declared before applicant all be unable to do without netted tensile materials, because think that prefabricated panels is exactly ornamental, just note its physical property: as whether freeze thawing resistance, water absorption rate, contraction etc. meet the requirements, think prefabricated panels and heat insulating material bond be compound to together with after anti-folding better, can not rupture, just do not note its mechanical property, do not need the realism understanding its mechanical property what understands, therefore for many years never propose the structure that do not need to establish netted tensile materials and design concept.
3, embodiment three injects basic matterial 9 in the sleeve pipe of crab-bolt 20, and embodiment three structure supporting parts 1-1 is that public technology is unexistent for local is arranged, neither be apparent.
4, " described vertical reinforcing bar 6-1 is arranged in the breach of insulation layer 15-3 embodiment five; Or vertical reinforcing bar 6-1 is arranged on the outside of topping 15-8-1 " be that public technology is unexistent, neither be apparent.
5, many fire protection constructions of embodiment six are that public technology is unexistent, neither be apparent.
6, the installation partial structurtes supporting parts 1-1 method that provides of embodiment seven, is that prior art is unexistent, neither be apparent.Because when having Cantilever Beams overhanging on major structure of construction now, be all that a formwork has been built, do not adopt the construction method of embodiment six.
7, embodiment 12 is become by the thin-coat plaster topping widely applied at present to do to install prefabricated panels topping, as installed cement fibrolite plate or calcium silicate board.Public technology does not install prefabricated panels topping on insulation layer, fixes with insulation layer and base course wall, forms regulation or the case history of heat-preserving energy-saving wall.
As aforementioned, thin-coat plaster heat-preserving wall is prevented fires and is badly affected world control greenhouse gas emission, and this problem does not solve for a long time, is just illustrating that embodiment 12 is not apparent.
Applicant studies wall technology from the beginning of 2002 4 months with all strength, and propose multiple wall technology patent successively, but just propose wall technology patent of the present invention until now, this also illustrates that the present invention is not apparent.
Embodiment one and embodiment 12, embodiment two and embodiment two and 13 common ground be:
1, changing situ wet operation thin protective layer of plastering is install the topping not needing scene to plaster, and topping is had prevent the performance of fire spread, does not need to rely on fire barrier to prevent fire spread.When the topping of precast heated board is plaster skin coat, be also to define thin-coat plaster topping and the topping meeting fire protection requirement by this standard.
2, prefabricated panels topping is also installed in indoor, increases building aseismicity, building Lateral resisting ability.
Technique effect of the present invention:
1, energy-saving heat-insulating wall good fireproof of the present invention, the present invention had both met construction stage fire safety, also can ensure the fire safety in Long-Time Service.Significant to guarantee people's livelihood safety, defense strategy safety, to promotion China so that global building energy conservation significant.
Even if insulation layer material is organic insulation material, even if its combustibility is the B2 level of flame retardant type, the present invention also has excellent fireproof performance.
External Thermal Insulation Technology for External, according to the present invention, can never occur, as Shanghai in November, 2010 Jing'an District teacher Lou great Huo, to cause the tragedy of tens of people's death; Definitely can not there is the massive losses that Shenyang feudal dynasty ten thousand prosperous restaurant catches fire, and etc. national external heat insulating wall fire casualty too numerous to enumerate.
2, energy-saving heat preserving of the present invention exceedes thin-coat plaster heat-preserving wall, and the passive type energy saving house easily promoting pole low energy consumption is built, and sees attached list data.
Subordinate list assembling external heat insulating wall and thin-coat plaster heat-preserving wall mean thermal transmittance contrast table w/m 2.k
Note:
1), subordinate list be supposition base course wall be 200mm concrete wall, the 3m standard width of a room in an old-style house, 3m are high, and window is respectively 2.1 × 1.5=3.15m 2, 2.4 × 1.5=3.6m 2, 2.7 × 1.5=4.05m 2, window-wall ratio is respectively 0.35,0.4,0.45 and calculates.
2), by " code for thermal design of civil buildings " GB50176 exposure draft revised, during EPS plate moisture content 15%, EPS plate coefficient of thermal conductivity 0.039w/m.k, and consider to calculate main wall heat transfer coefficient after socketing steel wire increases heat transfer; Coefficient of thermal conductivity=0.039 × 1.2=0.0468w/m.k that thin-coat plaster heat-preserving wall presses the correction of EPS plate calculates.
If actual moisture content is lower than 15%, then wall heat transfer coefficient is lower than numerical value in subordinate list.
3), the heat bridge of energy-saving heat-insulating wall of the present invention comprises the heat bridge that locally cornices, the heat bridge that window has reinforcing bar insulation layer thinning; The heat bridge of thin-coat plaster heat-preserving wall is hole heat bridge, by the regulation of Appendix D in " Heilongjiang Province's Residential Buildings Energy 65% design standard " DB23/1270, calculates hole heat bridge to the impact of body of wall mean coefficient.
From subordinate list, the heat bridge of energy-saving heat-insulating wall of the present invention and the heat bridge of thin-coat plaster heat-preserving wall contrast, and are not orders of magnitude.This is because:
1), heat-insulating bridge-cut-off hole can significantly reduce window heat bridge, can eliminate balcony slab heat bridge, and cornice available light weight aggregate concrete for the local of severe cold area and passive type energy saving house.
If curtain wall decoration, have the curtain skeleton of supporting assembling external heat insulating wall to pass insulation layer, can directly be connected with the steel plate on reinforcing bar in topping, stainless steel sockets steel wire only increases wall heat transfer coefficient about 0.05 ~ 0.1w/m 2.k, the heat transfer that socketing steel wire increases is far smaller than and the heat transfer of thin-coat plaster heat-preserving wall curtain skeleton increase.
2), seam between EPS plate in embodiment seven precast heated board, significantly can reduce the ventilative adverse effect to EPS plate coefficient of thermal conductivity of seam of installing fritter EPS plate.
Because there being supporting assembling external heat insulating wall heat bridge very little, therefore window-wall ratio size is very little on the impact of mean thermal transmittance; But thin-coat plaster heat-preserving wall is because of the impact of hole heat bridge, very large on the impact of body of wall mean thermal transmittance.
3, the present invention is while carrying out body of wall energy-saving heat preserving engineering; utilize some heat insulating material and prefabricated panels topping to have the feature of certain tensile strength, increase antidetonation, the wind loading rating of building, reduce construction cost; improve safety grade of architecture, significant.
4, proposition prefabricated panels of the present invention is as topping to guarantee topping quality, extends heat-preserving wall durable years favourable, is conducive to social sustainable development.
Qualitative problems of construction as thin-coat plaster topping cracking, efflorescence is too many, and durability is bad.And fiber reinforced cement board can be not less than 50 years as durable years during topping, and generally can not ftracture as thin-coat plaster topping, to the hidden danger that fire safety causes, not only can not fire spread, more can not occur with a loud crash.
5, the present invention with B2 level heat insulating material as B2 level EPS plate makes precast heated board, can reduce heat-preserving wall cost greatly.
Adopt the structure of embodiment eight, nine again, there is not or seldom exist in-site installation EPS plate and there is a large amount of gap to insulation adverse influence, also can reduce the thermal transmittance that EPS plate coefficient of thermal conductivity 20%, EPS plate thickness 280mm just can meet the requirement of passive type energy saving house, price is about 80 yuan/m 2, adopt B1 level graphite benzene plate to reduce wall heat insulation material price about 120 yuan/m than present thin-coat plaster heat-preserving wall 2more than.
6, assembling technology is introduced in wall thermal insulating engineering by embodiment of the present invention one ~ 11, significantly reduce site operation compared with the prior art to plaster wet trade, installation rate is fast, convenient construction, solve need increase heat-preserving wall fire resistance property time, need increase to plaster protective layer thickness, but construction is difficult to the difficult problem that realizes; And precast heated board can as the template of cast-in-situ concrete, convenient construction, greatly reduces concrete blinding construction costs again, can promote new countryside construction.
7, embodiment of the present invention 12 ~ 14 can as embodiment one ~ 11 supplement, the two fit applications.
Embodiment 12 ~ 14 not as adopting embodiment one ~ 11 easy for installation, and is helpless to install organic insulation layer fire safety in solution construction.But exterior wall or balcony fence be arc moulding be incubated time, prefabricated arc precast heated board may be inconvenient, with regard to working embodiment 12 ~ 14.
