Description

A kind of exterior wall external insulation composite wall body that supporting is arranged
Technical field
The exterior wall external insulation composite wall body that the present invention relates to build.
Background technology
The purpose of energy saving building space enclosing structure insulation is, by space enclosing structure being taked to be incubated heat transmission inside and outside the measure confinement cells, reduces guaranteeing the indoor comfortable thermal environment heat supply or the required energy consumption of freezing.The exterior wall of heating regional architecture cans be compared to our cotton dress, and the exterior wall that summer, the hot area built cans be compared to the shell of refrigerator.Energy-saving heat-insulating wall all is a heat insulating effect of improving traditional body of wall by the way of additional thermal insulation at present, the transmission of the inside and outside heat of confinement cells, but the heat bridge that is difficult to eliminate for a long time becomes the energy-conservation bottleneck of obstacle body of wall.
One, about the influence of the pluses and minuses of current various energy-saving heat preserving combined walls and heat bridge to wall insulation performance:
1, analyze exterior wall and paste EPS plate thin plastering heat-preserving wall:
At present, it is that heat insulation effect is best that exterior wall is pasted the thin heat-preserving wall of plastering of EPS plate (or XPS plate), and cheapest heat-preserving wall is so EPS plate thin plastering heat-preserving wall is used at most in China.Even at door and window hole heat bridge is arranged also: Figure 8 shows that the insulation layer of door and window hole sidewall was thin, is incubated bad when door and window was installed in basic unit body of wall middle part but be incubated best EPS plate thin plastering heat-preserving wall; Figure 10 shows that door and window is installed in basic unit body of wall exterior angle, the outdoor distance of the outer angular distance of basic unit's body of wall is short, and the door and window hole insulation is also bad, and arrow scope length L is heat bridge position insulation layer thickness among Fig. 8 and Figure 10.
The numerical value that provides the heat bridge of Fig. 8 and Figure 10 in " Heilongjiang Province's Residential Buildings Energy 65% design standard " is that the thin heat-preserving wall hole of plastering exists linear thermal transmittance ψ value to reach the heat bridge of 0.1w/m.k! Because of door and window hole quantity is many, the heat bridge influence is very big, and the body of wall hole periphery heat bridge of window-wall ratio 0.3 increases body of wall mean thermal transmittance 0.1w/m approximately 2Window-wall ratio is big more, and the influence of heat bridge is big more.The door and window hole heat bridge cans be compared to people's neck, and weather is cold especially, and neck must be placed a mao scarf.But people's neck has only one, and the door and window quantity of building is a lot, so heating area indoor/outdoor temperature-difference greatly the time, the door and window hole heat bridge has a significant impact building energy conservation.
A large amount of balcony slab and air conditioner plates of encorbelmenting also are big heat bridges in the dwelling house, even balcony slab is pasted the EPS plate of thickness 100mm up and down all, its linear thermal transmittance ψ value also reaches 0.2w/m.k.The balcony slab of encorbelmenting has the thick EPS plate insulation of 100mm up and down, and during window-wall ratio 0.3, the balcony slab heat bridge is to the about 0.05w/m of the influence of body of wall mean thermal transmittance 2.k (accounting for exterior wall length 40~50% by balcony slab length calculates), EPS plate thin plastering heat-preserving wall hole heat bridge and balcony slab heat bridge always increase the about 0.15w/m of influence of body of wall mean thermal transmittance 2.k, thus,, draw the insulation of main wall body EPS plate thin plastering thermal transmittance that should reach approximately and the insulation layer thickness that needs, see attached list 1 for satisfying " Heilongjiang Province's Residential Buildings Energy 65% design standard ".By subordinate list 1 as seen, the thermal transmittance that building energy conservation body of wall below 8 layers reaches regulation is too difficult, if can reduce the hole heat bridge, dwindles the poor of main wall body heat transferring coefficient and body of wall mean thermal transmittance limit value, the target of building energy conservation just is easier to realize that this is one of free-revving engine of the present invention.

Annotate: 1, subordinate list 1 data contain heat-preservation balcony plate heat bridge, hole heat bridge, the influence of beam support spare heat bridge of encorbelmenting to the body of wall mean thermal transmittance.
2, severe cold (A) district body of wall mean thermal transmittance limit value also need reduce 0.05w/m than (B) district 2.k, the main wall body ripe coefficient of biography that should reach more is difficult to realize.
If balcony slab is not incubated up and down, then increase the about 0.1w/m of body of wall mean thermal transmittance limit value again 2More do not reach the energy conservation standard of requirement.
But the serious problems of knowing altogether below the thin heat-preserving wall of plastering also exists:
1), the fire prevention dangerous, outside finish is dangerous.
There is bad, the outside finish unsafe problems of fire prevention in thin heat-preserving wall of plastering.Germany does the fire barrier at the door and window mouth and every two-layer with rock wool, and surpass the above building of 20m and will use rock wool heat-preservation, China's rock wool quality is not all right, the quarantine measures of not preventing fires, because of thin low, the good heat insulation of heat-preserving wall cost of plastering, China comprises that highrise building adopts in a large number.The thin plastering exterior wall heat-insulation system bans use of in the U.S. owing to relate to serious fire safety problem; In Britain, the building more than 18 meters does not allow to use; In Germany, the building more than 22 meters does not allow to use.
2), durability is bad, maintenance capacity is big.
Macromolecule adhesive in the polymer mortar, glass fiber reticular cloth influence its durability in the adverse circumstances that outdoor ultraviolet ray, wind and rain degrade.The thin heat-preserving wall of plastering that Germany pastes the seventies is removed the thin topping of plastering in maintenance, pastes the EPS plate insulation of 100mm on the original EPS plate of pasting again.The a large amount of engineerings of China are few because of the bonding adhesive effective content, and the glass fiber reticular cloth alkali resistance is bad, and only several years outer masks just ftracture, and the thing that needs repairing happens occasionally.
2, the heat bridge of steel wire net rack cement sandwiched plate heat-preserving wall
Steel wire net rack cement sandwiched plate heat-preserving wall is except that the heat bridge that above-mentioned EPS plate thin plastering body of wall is arranged, every square metre also has 200 Φ 2 steel wires to penetrate insulation layer increase heat transfer, the heat transfer that also has connecting reinforcement to increase with the basic unit body of wall, the revised coefficient of thermal conductivity of EPS plate should be greater than 0.08w/m.k, increasing by 60% than EPS plate thin plastering body of wall conducts heat, but also insulation layer contained wet adverse effect during meter used for a long time, and required insulation layer thickness will increase a lot than the thin heat-preserving wall of plastering.
3, sandwiched thermal-insulating wall heat bridge
Use sandwiched thermal-insulating wall at present in large quantities in the Heilongjiang Province, even highrise building is being widely applied also.Sandwiched thermal-insulating wall exists along the concrete Guttr board heat bridge of building border, and exterior wall is likened to cotton dress, and sandwiched thermal-insulating wall has uninsulated waistband---Guttr board on the coagulation together for every layer.Also have hole periphery heat bridge, interior siphonal lobe masonry sockets the reinforcing bar heat bridge.Fig. 3 represents the loss route (curve shown in) of the sandwiched thermal-insulating wall of Guttr board heat bridge place paste heat-preserving bar at Guttr board heat bridge place heat.Even but Guttr board heat bridge outer end paste heat-preserving bar as shown in Figure 3 is very little because of prolonging the heat bridge route, and the improvement of insulation is worked hardly.According to the linear thermal transmittance value of the uninsulated balcony outrigger base of thickness 120mm in " Heilongjiang Province's Residential Buildings Energy 65% design standard ", suppose Guttr board thickness 80mm, the about 0.43w/m.k of linear thermal transmittance of Guttr board heat bridge.Heat bridge in the floor height 2.8m dwelling house is analyzed the influence of mean thermal transmittance, pressed window-wall ratio 0.3, balcony slab insulation layer EPS plate thickness 100mm up and down, sandwich heat preserving wall body Guttr board heat bridge increases the about 0.15~0.2w/m of body of wall mean thermal transmittance 2.k, add hole periphery heat bridge (be partial to dangerous calculating, still estimate), always increase the about 0.25~0.3w/m of body of wall mean thermal transmittance by the linear thermal transmittance of the thin hole heat bridge of plastering 2By severe cold (B) the district body of wall mean thermal transmittance limit value of stipulating in the energy Saving Design of Residential Buildings decision table in " Heilongjiang Province's Residential Buildings Energy 65% design standard ", the sandwich thermal insulated thermal transmittance that should reach approximately of the main wall body that can draw sees attached list 2.
Subordinate list 2 severe cold (B) district residential building is considered linear thermal transmittance influence, the thermal transmittance that sandwich thermal insulated main wall body should reach approximately and the insulation layer thickness that needs

9~13 layers 0.28 0.5 0.2~0.25 250~200
4~8 layers 0.3 0.4 0.1~0.15 450~300
<<3 layers <<0.5 0.3 0~0.05 Can not reach
Annotate: 1, subordinate list 1 data contain heat-preservation balcony plate heat bridge, hole heat bridge, the influence of beam support spare heat bridge of encorbelmenting to the body of wall mean thermal transmittance.
2, severe cold (A) district body of wall mean thermal transmittance limit value also need reduce 0.05w/m than (B) district 2, more be difficult to reach.
But sandwiched thermal-insulating wall hole heat bridge should be more much bigger than EPS plate thin plastering heat-preserving wall hole heat bridge, and the thermal transmittance that the main wall body should reach approximately in the attached table 2 all can not satisfy, and considers also null(NUL) of numerical value that sandwiched thermal-insulating wall hole heat bridge increases again.Stipulate that in " Code for design of masonry strucres " GB50003 sandwich thermal insulated middle insulation layer thickness should not be greater than 100mm, so may not satisfy the requirement of subordinate list 2.
Sandwiched thermal-insulating wall also has other problem: the slit between the EPS plate of installation and hole periphery masonry, concrete Guttr board and the EPS plate is very big, is difficult to control in the construction, makes the inside and outside air in EPS plate both sides form the convection current increase and conducts heat; The outer decoration of sandwiched thermal-insulating wall is generally face brick, the heating phase has intercepted indoor steam and has distributed to outdoor, water capacity is big in the insulation layer of severe cold area, EPS plate water capacity considerably beyond regulation is not more than 15% regulation, heat insulation effect reduces, and socket the heat transfer that reinforcing bar increases in addition, what do not comprise all in above analysis a large amount of sandwich thermal insulated building of having built has to reach energy-conservation 50% standard? more can not satisfy the standard of severe cold area energy-conservation 65%.
Be pointed out that also the durable years that sockets reinforcing bar brush corrosion resistant coating between the interior siphonal lobe masonry is limited, under wet environment, socket after about 20 years and socket reinforcement corrosion totally between the inside and outside leaf body of wall that there is the danger of hurting sb.'s feelings of collapsing in the siphonal lobe masonry of highrise building!
Some countries as Russia adopt the way of three layers of body of wall therebetween double insulation in the world, the heat bridge route prolongs can reduce heat bridge, but the influence of heat bridge is still very big, and its structure is not suitable for highrise building, increase body of wall and foundation cost, significantly reduce usable floor area.
4, insulation blocks body of wall
The insulation blocks body of wall is approaching at the heat bridge and the sandwiched thermal-insulating wall heat bridge at Guttr board and hole, but also have following problem: 1. insulation layer is by sand, slag, haydite, cement etc. cut apart bitty insulation blocks wall, goal analysis from the trap heat transmission, its structure is unreasonable, does the insulation blocks wall of severe cold area main wall body region need the how thick requirement that could satisfy body of wall mean thermal transmittance in the subordinate list 2? if with the EPS plate, the heat insulation effect of XPS plate is likened with eider down or cotton, the higher material of those more petty coefficient of thermal conductivity can be likened and makes outmoded cotton or catkin, and insulation blocks can be likened and does to be mingled with slag in eider down or the cotton, sand, the body of wall of cement or material.Do 2. some constructional drawings concentrate about the data of insulation blocks body of wall whether considered the influence of unfavorable factor in the construction, and insulation layer contains wet influence to heat preservation and energy conservation effects in long-term the use?
5, inside heat insulation wall body
Inside heat insulation wall body exists along building border floor heat bridge, slab thickness must be greater than Guttr board thickness, also has partition wall heat bridge, partition walling thickness is 0.37m, 0.24m in the multistory building, the concrete wall of the about 0.2~0.3m of highrise building thickness, a large amount of uninsulated partition wall of inside heat insulation wall body---like between the sheet before and after the cotton dress just cloth be to have connected, but there have cotton to become heat bridge near seam crossing to be cold thoroughly.The influence of inside heat insulation wall body heat bridge is farther much larger than the sandwiched thermal-insulating wall heat bridge! Inside heat insulation wall body is like there being on the cotton dress of wearing a rule not have the position of cotton, is incubated badly certainly, even the flourishing Japan of science and technology also use interior insulation, spraying polyurethane is incubated on indoor wall.Point out in " civilian construction energy-saving design standard " JGJ26-95 appendix C of China: under interior heat-retaining condition, peripheral heat bridges such as concrete beam, post make the mean thermal transmittance of body of wall increase by 51~59%.Regrettably, the North China has built a large amount of interior heat-preserving buildings.
6, curtain wall decoration body of wall
A large amount of shaped steel of curtain wall decoration building that adopt are intensive, the about 0.8~1.2m of spacing, and the steel heat output is too big, and its coefficient of thermal conductivity is concrete 33 times, how to satisfy the requirement of building energy conservation?
7, prefabricated thermal insulation wallboard wall
Prefabricated heat preservation wall board wall body is used for the frame construction infilled wall, and price is higher.In addition, also there is following problem in the prefabricated thermal insulation wallboard wall:
1), prefabricated panel has the seam heat bridge more, the seam heat bridge is very big to the influence of body of wall mean thermal transmittance, the engineering that has adopts the heat-insulation wall plate of prefabricated light steel frame, seam crossing cracking saturating cold dewfall in back is installed, make the indoor floor perk, become the indeterminable quality problems of general maintenance (unless if thoroughly solving the sticking again one deck insulation layer of exterior wall).
2), prefabricated panel and belonging to being connected of frame beam column with the external hanging type of crab-bolt or pre-embedded steel slab welding installs more, stressed indeterminate, stress is concentrated.
3), crab-bolt is divided into metal crab-bolt and plastics crab-bolt, its durability is doubtful.
Pass insulation layer, do not have the steel of alkaline environment protection perishable, accelerated corrosion under dampness especially.The metal crab-bolt preferably should be the stainless steel of higher level, and next should be the steel part of galvanizing or chromium plating, but the crab-bolt of a great deal of engineering is a common iron.The higher plastics of intensity are polypropylene and nylon at present, but these two kinds of plastics are not ageing-resistant, polypropylene durable years 10~30 years, and we are difficult to judge its durable years.Plastics are applicable to and should not be imbedded in the wall as main bearing member as easily changeable parts.
Insulation situation to bodies of wall such as more sandwich thermal insulated, the interior insulation of heat bridge, insulation blocks is made a metaphor: the insulation layer in these external walls is as the warming cotton of exterior wall cotton dress, but a lot of concrete of quilt, mortar between the cotton, do even steel etc. keep apart, how good heat insulation?
The inventor of present patent application has proposed the patent No. 200410002698.7; the patent of invention name is called " support is arranged, the anti-seismic heat-preservation combined wall of reinforced concrete external protection is arranged "; and the patent No. 200610153289.6; the patent of invention name is called two patents of " binding composite heat preservation wall that supporting is arranged ", and there is the hole heat bridge too in these two patents.For guaranteeing the trimming bar protective layer thickness; hole floated coat thickness needs 30mm; the about 0.2w/m.k of linear thermal transmittance by hole cement sand bed heat bridge; even hole paste heat-preserving moulding; make heat bridge length extend to 200mm; linear thermal transmittance also reaches about 0.1w/m.k, and is unfavorable to energy-saving heat preserving, and increases cost.Because of door and window hole quantity is many, hole floated coat heat bridge is very big to the building energy conservation influence.
Heat bridge has increased architect's design-calculated difficulty more, and because of the wall heat transfer amount height of worrying that these heat bridges are more, do not reach the heating requirement, thermal performance design engineer have to be to estimating such as the heat consumption of bodies of wall such as sandwiched thermal-insulating wall, insulation blocks more, how does the building energy conservation target of expection realize? 2003~2005 years heating seasons of academy of China Constrution Academe part energy saving building follow-on test in Beijing is found, reached the only energy-conservation 7%! of energy-conservation 37%, energy-conservation 30% building reality by the building measured result of energy-conservation 50% index formation Present energy-conservation 65% standard of some regional executeds is subjected to that the body of wall technology is incomplete to be influenced, and estimated average does not reach the energy conservation object of national regulation yet.
The problem that current energy-saving wall technology exists more than has been described, the problem that the energy-saving wall technology exists is to energy-saving and emission-reduction, to building low-carbon (LC) society, the sustainable development of society being had a significant impact, and sequelae is serious.
Heat runs off, particularly the calculating of various heat bridge loss heat is complicated problems very, because we have a process to the understanding of heat bridge and to the understanding of some constructional materials performances, walked detour, and we have paid tuition fee.All have under the situation of various problem in various body of wall technology, investor and design side also are absorbed in a kind of helpless when selecting energy-saving wall.
Be effectively to reduce the hole heat bridge, improve body of wall energy-saving heat preserving level, convenient construction, reduce cost, remedy the deficiency of my aforementioned patent, of the present invention a kind ofly have the exterior wall external insulation composite wall body of supporting to solve this problem.
Two, analyze the in-problem reason of current wall thermal insulation technology, propose the method for dealing with problems:
The reason of problem: the thin heat-preserving wall of plastering is only to rely on bonding that insulation layer is connected with body of wall, and as topping, fire prevention is bad naturally with 3~4mm cement polymer mortar folder glass screen cloth in the macromolecule insulation layer outside, and outside finish is dangerous, and durability is bad.Sandwich thermal insulated, insulation blocks, inside heat insulation wall body are installed method Taiyuan beginning, too simple of heat insulating material, and natural heat bridge is many, and heat insulating material that also has such as steel wire net rack benzene plate coefficient of thermal conductivity height are incubated bad.
The problem that energy-saving wall exists two reasons that have not been resolved for a long time: the first does not take reliable structural measure both to guarantee external protection safety, reduces heat bridge again to greatest extent; It two is not solve plaster reliable bonding with the macromolecule insulation layer of conventional cement mortar, thereby avoids the problem of the common quality defect of floated coat hollowing cracking; It three is that hole heat bridge problem is not effectively solved all the time, comprises that my aforementioned two patents do not solve hole heat bridge problem yet, and the hole structure trouble.
Be effectively to reduce the hole heat bridge, improve body of wall energy-saving heat preserving level, convenient construction, reduce cost, remedy the deficiency of my aforementioned patent, of the present invention a kind ofly have the exterior wall external insulation composite wall body of supporting to solve this problem.
Summary of the invention
The purpose of this invention is to provide the exterior wall external insulation composite wall body structure that supporting is arranged.
The objective of the invention is: one, reduce heat bridge significantly, on the basis of the aforementioned invention of the inventor, eliminate or reduce the hole heat bridge significantly, dwindle the poor of main wall body heat transferring coefficient and body of wall mean thermal transmittance limit value, the target of realization building energy conservation; Two, provide a kind of reliable energy-saving heat-insulating body structure, on the basis of reducing heat bridge to greatest extent, also will guarantee external protection safety; Three, a kind of combined wall structure of convenient construction is provided; What four, provide that there is a curtain wall decoration of decorating big plate a kind of outside is provided with the encorbelment combined wall structure of beam of concrete bearing.
First kind of the present invention has the exterior wall external insulation composite wall body of supporting to be: the present invention includes basic unit's body of wall, concrete hanging top supporting member, insulation layer, netted tensile materials, vertical reinforcement, topping, door and window and major structure of construction; Described basic unit body of wall is the body of wall of concrete wall, bearing masonry wall, non-bearing lightweight masonry infilled wall or steel wood, bamboo wood; Described insulation layer is macromolecule heat insulating material or mineral wool felt or straw plate or honeycomb card board or thermal insulation mortar or foamed concrete; Described netted tensile materials is alkaline-resisting screen cloth or wire lath or bamboo reinforcement net; Described topping is cement mortar or pea gravel concreten, or the cement mortar of modification or pea gravel concreten, or thermal insulation mortar; Described major structure of construction is concrete component or steel member, and major structure of construction comprises beam, plate, post, wall, basis; Fixedlying connected with major structure of construction in the inner of concrete hanging top supporting member, or is fixed in basic unit's body of wall of bearing masonry; Insulation layer is fixed on the outside of basic unit's body of wall and major structure of construction; Vertical reinforcement is weldingly fixed on the pre-embedded steel slab of external end head of concrete hanging top supporting member, and the door and window hole side is provided with vertical reinforcement; There is netted tensile materials the outside of vertical reinforcement or inboard, and netted tensile materials is fixedlyed connected with vertical reinforcement; Vertical reinforcement and netted tensile materials are dived and are embedded in the topping, or alkaline-resisting screen cloth sticks on the surface of topping; Door and window of the present invention is installed on the insulation layer of hole, is provided with topping in the outside of insulation layer and the indoor and outdoor both sides of door and window, forms the exterior wall external insulation composite wall body that supporting is arranged of hole heat insulation break bridge.
The present invention reduces the effect of Guttr board heat bridge, partition wall heat bridge and can liken like this: the exterior wall in heating area cans be compared to cotton dress, and of the present invention a kind ofly have the exterior wall external insulation composite wall body of supporting not have uninsulated waistband---the concrete Guttr board together that every layer is reserved on sandwich heat preserving wall body, the insulation blocks body of wall; Do not have a large amount of uninsulated partition walls of inside heat insulation wall body yet---like between the sheet before and after the cotton dress just cloth be to have connected, but near seam crossing, do not have cotton; There is not be mingled with in the cotton of insulation blocks body of wall the not insulation layer of heat insulating material such as a large amount of mortars, slag yet.
The present invention reduces the effect of door and window hole heat bridge and can liken like this: the exterior wall in heating area cans be compared to cotton dress, when we feel that neck is cold, to place mao scarf and just feel warm, if only solve the cold problem of neck by the thickness that increases cotton dress, effect is unconspicuous.By rational door or window hole structure, can reduce the heat transfer heat waste of door and window hole periphery, this is like having placed the hair scarf on the neck.But people's neck has only one, and the door and window quantity of building is a lot, and is so the heat that the hole heat bridge runs off is a lot, very big to the building energy conservation influence.When particularly requiring wall heat transfer coefficient low more, the meaning of hole heat insulation break bridge is big more.This is cold especially like weather, and it is the same that neck must be placed mao scarf.
The concrete hanging top supporting member that a kind of exterior wall external insulation composite wall body that supporting arranged of the present invention only accounts for Guttr board heat bridge about 10% is a heat bridge, it is like the clasp of cotton dress, be to guarantee that wall thermal insulating system safety is requisite, except clasp---the concrete hanging top supporting member, the insulation layer that forms connects, seem fur-lined jacket, down jackets, wadded jacket in insulation, so good heat insulation.If further reduce the heat transfer of concrete hanging top supporting member, need use light weight aggregate concrete, but only otherwise can the interior dewfall of generation chamber,, generally needn't use light weight aggregate concrete because of concrete hanging top supporting member area is little.

The specific embodiment
The specific embodiment one: referring to Fig. 1~Fig. 6, a kind of exterior wall external insulation composite wall body by supporting of present embodiment is made up of basic unit's body of wall 1, concrete hanging top supporting member 10-5, insulation layer 3, netted tensile materials 5, vertical reinforcement 4, topping 8, door and window 20 and major structure of construction 10; Described basic unit body of wall 1 is the body of wall of concrete wall, bearing masonry wall, non-bearing lightweight masonry infilled wall or steel wood, bamboo wood; Described insulation layer 3 is macromolecule heat insulating material or mineral wool felt or straw plate or honeycomb card board or thermal insulation mortar or foamed concrete; Described netted tensile materials 5 is alkaline-resisting screen cloth 5-1 or wire lath 5-2 or bamboo reinforcement net 5-3; Described topping 8 is cement mortar or pea gravel concreten, or the cement mortar of modification or pea gravel concreten, or thermal insulation mortar or EPS plate thin plastering insulation bar; Described major structure of construction 10 is concrete component or steel member, and major structure of construction 10 comprises beam, plate, post, wall, basis; Fixedlying connected with major structure of construction 10 in the inner of concrete hanging top supporting member 10-5, or is fixed in basic unit's body of wall 1 of bearing masonry; Insulation layer 3 is fixed on the outside of basic unit's body of wall 1 and major structure of construction 10; Vertical reinforcement 4 is weldingly fixed on the pre-embedded steel slab of external end head of concrete hanging top supporting member 10-5, and the door and window hole side is provided with vertical reinforcement 4; There is netted tensile materials 5 outside of vertical reinforcement 4 or inboard, netted tensile materials 5 and vertical reinforcement 4 fixedly connected (colligation or by being connected with the topping of plastering is bonding); Vertical reinforcement 4 is dived with netted tensile materials 5 and is embedded in the topping 8, or alkaline-resisting screen cloth 5-1 sticks on the surface of topping 8; Door and window 20 is installed on the hole insulation layer 3, is provided with topping 8 in the outside of insulation layer 3 and the indoor and outdoor both sides of door and window 20, forms the exterior wall external insulation composite wall body that supporting is arranged of hole heat insulation break bridge.
The cement mortar of modification or pea gravel concreten are for adding the cement mortar or the pea gravel concreten of materials such as Admixture, flyash; also comprise and add cement polymer mortar or the polymer concrete that bonding adhesive forms; the protective layer used polymer mortar or the polymer concrete of reinforcement location are being arranged; prevent to corrode useful to the protection reinforcing bar; can reduce the protective layer thickness of plastering; topping is plastered and with polymer mortar or polymer concrete resistance is split, and it is the most favourable to increase durable years.
When the insulation layer of present embodiment is macromolecular material, insulation layer EPS plate for example, should adopt the good heat insulating material of fireproof performance at door and window hole, the insulation layer of combined wall is exactly two kinds of materials like this, can with mineral wool or thermal insulation mortar as insulation layer around the hole.Thermal insulation mortar has kervit microbead insulated sand slurry, and its advantage is that fireproof performance is good, and material is extensive, and the thermal insulation mortar coefficient of thermal conductivity can reach 0.07w/m.k, and the heat insulation effect of mineral wool is higher than thermal insulation mortar.The heating area, both sides also should be adopted thermal insulation mortar or be pasted EPS plate thin plastering insulation bar as topping 8 in the outside inside and outside the door-window section bar of hole, be shown in Figure 1 at the position, hole, thermal insulation mortar or EPS plate are both as insulation layer, thermal insulation mortar or the thin insulation bar of pasting in the outside, hole of plastering can be used as the both sides topping of hole door-window section bar again, thermal insulation mortar or the album leave insulation bar of plastering can play two effects as door-window section bar both sides, hole topping 8: 1, further prolong indoor basic unit body of wall and outdoor distance, minimizing hole heat bridge; 2, prevent the indoor dewfall of door-window section bar.Adhesive powder-polystyrene granule thermal insulation mortar is met the atrophy of fiery benzene plate particle, forms cavity, also can block fire spreading, so can be used as the hole insulation layer, also can be used as the topping of door and window indoor and outdoor both sides.In the non-heating region or non-severe cold area, wall heat transfer coefficient is required when not being very strict, the inside and outside both sides of hole door-window section bar can be with cement mortar as topping 8, but should guarantee door and window inboard in winter dewfall not.The coefficient of thermal conductivity of foamed concrete is 0.1~0.25w/m.k, also can be used on the insulation layer of door and window hole periphery, promptly insulation layer can be different materials at diverse location, for increasing water resistance, the foamed concrete planted agent adds the elasticity macromolecule adhesive, helps preventing that the hole from crack and waterproof taking place.
Present embodiment is installed in door and window on the insulation layer of hole; the protection of plastering again in the door and window both sides; promptly do not have the cement mortar topping heat bridge of plastering between doorframe and window frame and insulation layer, the cement mortar topping heat bridge of plastering is cut off by door and window, has prolonged indoor basic unit body of wall exterior angle and outdoor distance.Shown in Figure 1, when on the floated coat of the indoor side at basic unit body of wall hole, also using the thermal insulation mortar plaster leveling (glue powder polyphenyl particle plaster insulation or the rock cotton board insulation of plastering is installed), further prolong basic unit body of wall exterior angle and outdoor distance again, promptly thermal insulation mortar or other heat insulating material are more favourable to wall thermal insulating as indoor hole plaster leveling layer.The insulation layer thickness of hole heat insulation break bridge structure should be greater than the thickness of door-window section bar, though otherwise also reduce the hole heat bridge, the heat-insulating bridge-cut-off effect will reduce.When the door-window section bar indoor and outdoor is plastered and is adopted heat insulating material, increased indoor basic unit body of wall exterior angle and outdoor distance again, and favourable to the doorframe and window frame insulation, conduct heat because of reducing doorframe and window frame, can further increase the building energy-saving heat insulation effect, the linear thermal transmittance of door and window hole even can be negative value! To reducing wall heat transfer coefficient, it is significant to improve the wall thermal insulating energy-saving effect.

The present embodiment hole has the exterior wall external insulation composite wall body that supporting is arranged of heat bridge to be applicable to wall heat transfer coefficient is required the heat-preserving wall that is not very strict, for example building of non-heating region.
My difference of aforementioned patent that the hole of present embodiment has the exterior wall external insulation composite wall body that supporting is arranged of heat bridge and background technology to mention is,
1, hole structure difference:
The patent No. 200410002698.7; it is concrete Guttr board, concrete window sill, window both sides to be set at the hole establish concrete reveal wallboard that the patent of invention name is called " support is arranged, the anti-seismic heat-preservation combined wall of reinforced concrete external protection is arranged "; the window sill below is provided with steel strut (seeing the claim 6 of this patent); and rely on the fixing hole Zhou Bianhuan window reinforcing bar of anchoring bar dowel on the surrounding member of hole, complex structure.The patent No. 200610153289.6, the patent of invention name is called " binding composite heat preservation wall that support is arranged ", be inner and outer ring window reinforcing bar to be set at the hole periphery, and between inside and outside bipassage ring window reinforcing bar, the window stiffener is set and sockets mutually, have in the window outside anchoring piece along 45 degree oblique with the basic unit's body of wall anchoring (seeing the claim 6 of this patent) of window periphery.The door and window of aforementioned two patents is installed on basic unit's body of wall, or is installed on the concrete component at hole, and it is fixing with wire lath and basic unit's body of wall 1 that the ironware nail is set, or steel nail is set passes insulation layer, oblique that wire lath and basic unit's body of wall 1 is fixing, increase heat transfer and unreliable, the construction trouble.
And the opening protection layer 8 of present embodiment and the floated coat at indoor basic unit body of wall 1 hole are connected as a single entity; in opening protection layer 8 or the surface net dress tensile materials 15 is installed; as accompany wire lath, alkaline-resisting screen cloth; or in opening protection layer 8 surface, paste alkaline-resisting screen cloth; construct very simply, do not have the various holes member of aforementioned two patents.Door and window both can be installed on basic unit's body of wall 1, also can be installed on the opening protection layer 8.Hole of the present invention has the exterior wall external insulation composite wall body construction that supporting is arranged of heat bridge simple and convenient, reduces cost.Also can waterproofing course be installed in topping, socket inside and outside the reinforcement by embodiment 16 or 17.
2, outside reinforcing bar and external metallization net are different with the connected mode of basic unit body of wall:
" support is arranged, the anti-seismic heat-preservation combined wall of reinforced concrete external protection is arranged " and mould coupled pole with steel shank or steel between outdoor vertical reinforcement in the patent and basic unit's body of wall and the agent structure and socket; steel pole is a reinforcing bar; steel pole and outdoor vertical reinforcement weld easy ablation macromolecule insulation layer; as not being welded to connect difficulty, steel is moulded the coupled pole complex structure and is inconvenient to connect.Outside reinforcing bar in " binding composite heat preservation wall that supporting is arranged " patent sockets by bolt, it is perishable in insulation layer that the ordinary steel bolt that passes insulation layer sockets part, if with stainless steel bolt cost height, and the design insulation layer thickness is not simultaneously, the specification difference of stainless steel bolt, the processing trouble increases difficulty of construction, increases floated coat thickness.The present invention sockets outdoor reinforcing bar and basic unit's body of wall with socketing steel wire inside and outside the pre-buried stainless steel, generally get final product with Φ 2.5 or Φ 3 stainless steel wires, and need not aforementioned two patents inside and outside socket part, simple structure, convenient construction, it is few to calculate by weight consumption, and cost is low.There is the exterior wall external insulation composite wall body easy construction that supporting is arranged of heat bridge at hole of the present invention, and cost is low, and is workable.
When insulation layer is foam concrete; in plastering, external protection in embodiment one~12 accompanies wire lath and outdoor reinforcing bar binding; and should be by the inside and outside steel wire that sockets; and plastics bloated nail external end head and wire lath colligation encryption fixing metal net; (the reinforcing bar inboard can be provided with the close net of alkaline-resisting screen cloth can to smear mortar cover earlier on wire lath; prevent that mortar from coming off), form the curtain wall of hanging.Then in the cavity of the curtain wall of hanging and basic unit's body of wall with cement foamed, form the sandwich layer of foam concrete, easy construction.
