Description

A kind of assembling external heat insulating wall
Technical field
The present invention relates to a kind of construction wall, particularly a kind of assembling external heat insulating wall.
Background technology
Plaster in heat-preserving wall engineering thin; because of the cement polymer mortar topping of insulation layer too thin; intercept propagation of flame effect poor; need to arrange higher fire barrier, if but while catching fire, wind-force is larger, and fire spread may be also very large; differ and stop surely spreading of the intensity of a fire completely; and the regulation according to China to differing heights architectural establishment rock wool fire barrier, while catching fire, the scope of sacrifice layer is respectively one deck, two layers, three layers, and sacrifice layer scope is too large.
Use the insulation layer of inorganic heat insulation material rock wool as the thin heat-preserving wall of plastering, but rock wool is also melted burning in the time that the intensity of a fire is larger, and the thin topping durability of plastering is bad.
After China's big fire several times, the 65# of Ministry of Public Security 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 has a lot of problems:
As to produce rock wool process be high energy consumption, high pollution process, can not popularize in an all-round way, we are building energy conservation, high energy consumption, high pollution on one side on one side.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, more very different than organic insulation material insulation, coefficient of thermal conductivity fluctuation range is large, and the difficult quality control of freezing and thawing performance, once in the future go wrong heat-preserving wall by efflorescence), Heavy Weight, once install insecurely, fall down danger.
All over China the combustibility regulation of heat insulating material is not quite similar now, for example Beijing specifies that heat insulating material combustibility all must not be lower than the B1 level of nonflammable, some areas specify that the combustibility of the high-rise building insulation material that exceedes 24m is not less than the B1 level of nonflammable, organic insulation material adds fire retardant after-combustion performance can reach B1 level, but price increases considerably, and some conventional fire retardants have destruction to environment.Adopt nonflammable B1 level heat insulating material, greatly increase body of wall energy-saving heat preserving cost, its effect is only safety while ensureing construction: electric welding spark can can't be put, but can not solve the long-term operational phase fire savety of the thin heat-preserving wall of plastering of organic insulation material.
The EPS plate of building the passive type energy saving house of utmost point low energy consumption needs 300mm thick, and the B1 level heat insulating material cost of employing nonflammable is too high, and because heat insulating material is too thick, while catching fire exactly, fuel is too many, very large to ensureing the people's livelihood potential safety hazard in the long-term use of building.
Applicant has been applied for several external heat insulating wall patents, than fireproof performance, the energy-saving heat preserving performance of the thin external heat insulating wall of plastering improve a lot now, but plaster in existence scene, wet trade is many, the inconvenient problem of constructing, and still there is fire safety potential problem in construction, in most engineerings, need with expensive B1 level organic insulation material for this reason.
Should solve the fire safety in construction and installation, also will ensure fire safety in long-term its use simultaneously, and convenient construction, reducing cost, the present invention proposes a kind of assembling external heat insulating wall.
Summary of the invention
The object of the invention is to provide a kind of assembling external heat insulating wall, to solve the problem described in background technology.
A kind of assembling external heat insulating wall of the present invention, it comprises base course wall, precast heated board, crab-bolt;
Described precast heated board comprises insulation layer, outer protection layer, has outer protection layer in a side of insulation layer, and insulation layer is connected with outer protection layer;
Described topping is prefabricated panels topping, or described topping is the plaster skin coat with some strength; Or described topping is the composite bed of prefabricated panels and plaster skin coat; Described outer protection layer has the satisfied performance that prevents fire spread;
Described insulation layer is inorganic heat insulation material or organic insulation material, or is the mixed material of inorganic heat insulation material and organic insulation material;
Precast heated board and base course wall be connected with following 2 kinds of modes, select one and select or select simultaneously:
1), precast heated board is placed in to base course wall outside, or in the side of the base course wall of cast-in-situ concrete, precast heated board is set,, through precast heated board precast heated board and base course wall is fixed by crab-bolt;
2), insulation layer inner surface is non-burnishing surface, forms engagement connection structure between the insulation layer of precast heated board and the base course wall of cast-in-situ concrete;
3), bonding with cementitious materials between precast heated board and base course wall;
To between precast heated board, connect, form a kind of assembling external heat insulating wall that precast heated board is installed.
The present invention and the difference of public technology are:
1, embodiment of the present invention one use crab-bolt is directly fixed precast heated board, forms assembling external insulation energy-saving wall.
In outer wall heat insulating engineering; very general with the fixing insulation layer of crab-bolt, for example, with the fixing insulation layer of plastic expanding nail, but public technology does not pass precast heated board by crab-bolt; fix the precast heated board of a side band matcoveredn, form regulation or the case history of assembling external insulation energy-saving wall.
Have following according to explanation the present invention neither prior art, neither be apparent:
1), from China's outer wall heat insulating situation analysis
China's regulation, when highrise building stickup organic insulation material carries out wall thermal insulating, the combustibility of organic insulation material should reach nonflammable B1 level, now density 20kg/m 3more than 700 yuan/m of B1 level EPS plate price 3, and the approximately 320 yuan/m of B2 level EPS plate price of general anti-flammability 3.But so-called nonflammable is only electric welding spark can not ignite, once breaking out of fire in the long-term use of building reaches the burning-point that polyphenyl plate more than 500 is spent, nonflammable B1 level EPS plate and the same the catching fire of flame retardant type B2 level EPS plate.The particularly present passive type energy saving house future development towards utmost point 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 25~30% of present Beijing, Harbin requirement energy-saving wall thermal transmittance, requires wall heat transfer coefficient to be not more than 0.15w/m 2.k.Adopting the thin of generally application to plaster when heat-preserving wall, 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 installs the insulation layer of naked; but by the compound upper topping of a side of insulation layer; form the precast heated board of a side matcoveredn (outer protection layer); penetrate installation by crab-bolt; plaster (except seam) with regard to noting be used in the topping that building-site carries out on metope insulation layer like this, form assembling external heat insulating wall.
At present China to such an extent as in world wide, promote under construction assembling that thinking that assembled architecture installs is only confined to major structure of construction and install and build the assembling of whole bodies of wall (energy-saving heat-insulating wall or non-energy-saving heat-insulating wall) is installed, also do not expect and in External Thermal Insulation Technology for External, carry out assembling installation.
Outer protection layer of the present invention prevents that fire spread performance is obviously far away higher than the insulation layer of the thin heat-preserving wall of plastering.
For example select the cement fibrolite plate of thick 8mm or the calcium silicate board topping as precast heated board; cement fibrolite plate or calcium silicate board coefficient of thermal conductivity are low (is 0.25~0.3w/m.k; it is 1/3 of cement mortar; trap heat ability is 3 times of cement mortar); particularly press again embodiment four and paste the netted tensile materials of installation; increase again adhered layer thickness, adhered layer also becomes outer protection layer, the about 12mm of topping gross thickness.
While being also plaster skin coat as topping; minimum thickness of plaster skin coat (being no matter manually to plaster or plaster skin coat that mechanical stitch forms) is wanted 10mm; paste Alkali-resisting fiberglass mesh, plaster skin coat adds pastes the about 14mm of topping gross thickness after Alkali-resisting fiberglass mesh again.
And the most of positions of the thin protective layer thickness of plastering of the thin heat-preserving wall of plastering are 3~5mm, minority privileged sites 5~7mm.No matter precast heated board of the present invention is stacking place or be installed on exterior wall, because a side matcoveredn protection, even if a certain precast heated board catches fire, flame is all difficult to spread.Therefore, the fireproof performance of the assembling external heat insulating wall of embodiment one in outer wall heat insulating engineering construction must be much higher than the thin heat-preserving wall of plastering that organic insulation material bare board is installed, and must meet and prevent fire spread requirement.
Therefore, make precast heated board just can meet the fire savety while heat insulating material being installed in construction and installation with B2 level EPS plate, in the time of the passive type energy saving house of construction utmost point low energy consumption, the thick B2 level of 300mm EPS plate can reduce by 100 yuan/m of cost 2more than.If embodiment one is apparent words, just needn't in highrise building, require the combustibility of organic insulation material to be increased to B1 level by B2 level, not only increase considerably cost, and be helpless to the fire savety in long-term use, situ wet operation is many, is difficult for ensureing workmanship.Even insulation layer be inorganic heat insulation material as rock wool, but rock wool also catches fire in 600 about degree, embodiment one also must improve the fireproof performance of rock wool.
The 65# of Ministry of Public Security literary composition forbidding organic insulation material in 2011, foam cement producer, user, the related personnel of designing unit just expect its alternative organic insulation material to paste on wall and be incubated by the thin heat-preserving wall structure of plastering, meet fire protection requirement, although the problem existing described in background technology is known by user, designing unit, is helplessly also having engineering to apply.
Get up although inorganic heat insulation material is fiery for the moment, but inorganic heat insulation material can not meet market demand, the supply of goods of for example rock wool is one of Harbin City urban applications not enough, the foam cement supply of goods is also nowhere near, and there are above-mentioned problems, cause the whole nation to stop work in the external wall outer insulation engineering overwhelming majority of founding a capital.
Since inorganic heat insulation material can not extensive use, thinking will improve the fire resistance of organic insulation material routinely, make its B2 level by flame retardant type bring up to the B1 level of nonflammable, but fire retardant is expensive, cause heat insulating material price significantly to go up, building exterior wall heat preserving cost is significantly gone up, and be helpless to the fire safety in the long-term use of building, and a lot of fire retardant there is pollution to environment.
The above-mentioned fire safety that only solves energy-saving heat-insulating wall from the fireproof performance of heat insulating material is conventional thinking.
China has to widely apply the thin heat-preserving wall of plastering for energy security, but other countries' application seldom, and at present only in the application of Northern Europe a few countries, and the building in Northern Europe only has hundreds of square meter, distance mostly; China 10000m 2. the building of scale is Minor Construction, and close proximity becomes the forest of fuel after building up.The thin heat-preserving wall of plastering directly threatens people's livelihood safety and defense strategy safety, once there is war, city will be sea of flame.
Even the patented technology that applicant has been announced; the thin topping of plastering is become to the thick topping of plastering of doing by supporting, reinforcing bar, gauze wire cloth hanging; can ensure the fire safety of external heat insulating wall in long-term operational phase; but still can not solve the fire safety of construction stage; or the B1 level organic insulation material that need to apply nonflammable in overwhelming majority's building, the cost of external heat insulating wall can not lower.But embodiment one had both met construction stage fire safety, significantly reduce cost, also ensure the fire safety in long-term use, form again assembling external heat insulating wall, reduce situ wet operation, accelerating construction progress, promotes Process of Housing Industrialization.
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, and forms insulation outside assembling
Because embodiment one is not that thinking solves the problem that external wall outer insulation exists routinely, it is not apparent.
Mostly be for many years material professional at research novel wall material, material professional does not have structure discipline knowledge, and the knowledge such as specialty of not constructing, only have the technician of branch professional knowledge to be difficult to capture the difficult point of wall technology.Because think that building energy conservation, wall reform are that thinking by Development of Novel materials for wall solves, thus government for many years for building energy conservation, wall reform drop into a large amount of nursery finances, but building energy conservation, wall reform progress are still difficult.
2), from world environments situation analysis:
The United Nations once issues report in March, 2007 and shows, the emission reduction effect that green building and building energy conservation are contained is greater than all greenhouse gas emissions that require 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 reducing greenhouse gas emission.
In spring in this year, the World Bank delivers report and warns: " unless take more multirow to move to climate warming, 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 shortage, 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 and claim, climate change is one of ultimate challenge of facing of global evolution, is descendants's meter, and various countries should undertake moral duty separately, the minimizing greenhouse gas emission of conscientiously taking action.……
Although global energy situation, environment situation are so severe, many countries still do not admit the thin heat-preserving wall technology of the plastering current extensive application of China, that be easy to catch fire, the such as state such as the U.S., Russia in the world.Dangerous because not only preventing fires at ordinary times, and occur once there is war or terrorist activity, the city of the thin heat-preserving wall of plastering is just easy to catch fire everywhere, even becomes sea of flame, and people's part of not hiding, will make country in extremely passive, dangerous situation.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.Even the heat-preserving wall setting of plastering thin reaches the fire barrier that 200mm~300mm is high, but still too large (three layers~one deck) of sacrifice layer scope, and wind-force size, temperature are just indefinite when catching fire, and fire barrier can not separate fire sometimes.
In body of wall energy-saving heat preserving technology, the contradiction of fire savety and energy-saving heat preserving does not have important breakthrough for many years all the time, and because body of wall energy-saving heat preserving technology relates to people's livelihood safety, defense strategy safety, a lot of countries are unwilling to paste on exterior wall that polystyrene board heat-insulatation is thin plasters.Although the external heat insulating wall patented technology of applicant has solved the problems referred to above, also easily eliminate hole heat bridge, in requiring low heat transfer coefficient, energy-saving heat preserving effect substantially exceeds the thin heat-preserving wall of plastering, but plaster in existence scene, wet trade is many, construct inconvenient problem, problem that cost is high, impact is applied in China, let alone allows the world know.Except the external heat insulating wall patented technology of thin plaster heat-preserving wall and applicant, the body of wall heat bridge of other body of wall power-saving technology is all many, and energy-saving heat preserving effect is all bad.
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 remains high building energy consumption in world wide.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, one of major reason is due to a lot of technical problems do not solve, otherwise how not to reduce discharging
China's building energy conservation, wall reform make 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 problem that external wall outer insulation exists routinely, are not apparent.
Only have with multi-subject knowledge, multiple material, the advantage of performance different materials, avoid its shortcoming, different materials is combined, optimize wall structure and just can capture the difficult point of 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, the precast heated board that embodiment one is positioned at wall between windows position in the vertical direction can be high arbitrarily, and in the time that seam crossing is not installed reinforcing bar, the precast heated board of breast can in the horizontal direction can be prefabricated by random length.As long as prefabricated, transport, lifting can accomplish, can be installed on base course wall by the present invention, this is that current all External Thermal Insulation Technology for External are not accomplished.
3, embodiment of the present invention two " crab-bolt external end head install fire proofing material; ... in the seam of outside topping, have fire proofing material " be that public technology is unexistent; neither be apparent; the heat-preserving wall of plastering because thin also exists plastics crab-bolt enclosing cover to be easy to thawing problem, and people does not go to solve.
4, " in the sleeve pipe of crab-bolt, to inject basic matterial " be that public technology is unexistent to embodiment three, neither be apparent.
5, embodiment five " structure supporting parts arranges for local " is that public technology is unexistent, neither be apparent.
6, " described outer protection layer is local setting to embodiment six, have exposed insulation layer, or exposed insulation layer is fluted in part outside the internal protection layer arranging, and outdoor vertical reinforcing bar is arranged in groove; Or outer protection layer is all to arrange, outdoor vertical reinforcing bar is arranged on the outside of precast heated board, and reinforcing bar has alkaline cementitious materials topping around " be that public technology is unexistent, neither be apparent.
7, the seam between embodiment eight precast heated boards is a kind of flexible joint, is that prior art is unexistent, neither be apparent.
Macromolecule adhesive in cement polymer mortar belongs to chemical materials, and Building technology personnel are rare understands chemical materials; Plaster in heat-preserving wall engineering thin; in the cement polymer mortar of bonding benzene plate, have macromolecule adhesive, because of Building technology, personnel are ignorant of, agent's low-price competition; make macromolecule adhesive content few, do not meet bonding requirements, time have the phenomenons such as external protection cracking, efflorescence to occur.If Building technology personnel know the kind of some macromolecule adhesives slightly, where produce, just can directly buy macromolecule adhesive oneself the preparation cement polymer mortar that chemical plant produces, not only reduce cost, and can ensure workmanship.Because of resilient glue material design chemical products, relate to multi-disciplinary, cross-cutting knowledge.Just because of this, in assembling body of wall, have at present people or not and propose flexible joint structure, because do not know what material can form flexible joint with, have no at present in Construction Technology regulation or construction drawings, and in concrete engineering, adopt flexible joint structure.
Technique effect of the present invention:
1, when insulation layer of the present invention is organic insulation material; even the B2 level that the combustibility of insulation layer material is flame retardant type; because outer protection layer is prefabricated panels or floated coat; its Thickness Ratio is thin plaster protection bed thickness many; add crab-bolt 20 external end heads fire proofing material 20-1 is installed, prefabricated panels seam crossing has fire proofing material, must have to meet to prevent fire spread performance; both meet construction stage fire safety, also can ensure the fire safety in long-term use.
2, the present invention just can meet with B2 level EPS plate making precast heated board the requirement that prevents fire spread, greatly reduces the cost of external heat insulating wall.
Adopt again the structure of embodiment seven, do not exist or seldom exist the on-the-spot EPS of installation plate to exist a large amount of gaps to insulation adverse influence, also can reduce EPS plate coefficient of thermal conductivity 20%, EPS plate thickness 250mm just can meet the thermal transmittance of passive type energy saving house requirement, and price is about 80 yuan/m 2, adopt B1 level to reduce approximately 120 yuan/m of wall heat insulation material price than the now thin heat-preserving wall of plastering 2more than.
3, reduce compared with the prior art the site operation wet trade of plastering, installation rate is fast, convenient construction; And precast heated board can be used as the template of cast-in-situ concrete, convenient construction, reduces again concrete blinding construction costs, can promote new countryside construction.
In new countryside construction, the light steel column load-bearing of thin-walled of current useful specification 60 × 60mm or 100 × 100mm, fills compressed straw slab or EPS plate plastered wall body, house rigidity is bad; the light steel column of thin-walled very easily corrodes, poor durability, the hidden danger that existence may collapse suddenly.Common brick has been cancelled gradually, and concrete load-bearing block is not universal in rural area, and peasant is ignorant of bonding adhesive, and it is very difficult that peasant oneself builds energy saving house, how to do
The present invention as cast in place concrete form, is not only applied to city lid high buildings and large mansions with precast heated board, also can be applicable to rural area.For example, with weak concrete (weak concrete that useless brick, weathering rubble are aggregate) load-bearing, precast heated board is cast in place concrete form, and between concrete, form the structure of engagement connection, without bonding adhesive, facilitate peasant to build single-layer energy-saving house.
4, precast heated board topping can be oriented strand board, utilizes the timber of environmental protection that a kind of purposes is provided to promoting.Because timber is unique " negative carbon " material, and the energy and water that processing oriented strand board is used than other material are all few, and its impact on environment is minimum, abundanter with the outer Ornamented facade of plank.
5, the present invention has expanded the assembled architecture process of housing industrialization, wide application.
In sum, the invention solves that the fire prevention that current external wall outer insulation engineering exists described in background technology is bad, cost is high, and the applicant public technology scene wet trade problems that greatly affect building energy conservation reduction of discharging that wait of plastering more, contribute to promote global building energy conservation, reduce greenhouse gas emission, promote Process of Housing Industrialization, there is important social effect.
