Description

Masonry or concrete structure with inner thermal insulating layer of multipurpose less permeable layer
The invention belongs to safeguard the improvement of the interior heat-preserving building thing of body of wall with masonry or concrete constructions.
Energy efficient building is divided into interior heat-preserving building thing, outer heat-preserving building thing, self-heat conserving building three classes.
For the building of safeguarding body of wall with masonry or concrete constructions (comprising various brick-concrete buildings, frame building, shear wall building etc.), adopt the foamed plastics veneer or whitewash the outer heat-preserving building thing of thermal insulation mortar at the wall face of safeguarding body of wall, the most common.
In the narration of this paper, the safeguarding that body of wall is meant and comprise body of wall, roof panel, floor and be that the building of major part or pith is safeguarded body with the body of wall of building.(building is safeguarded body, also comprises transparency window and door.)
Since building safeguard the laminating external thermal insulation of body of wall be easy to because of expand with heat and contract with cold, expose to the sun and rain, aged deterioration; cause external thermal insulation to comprise that its anti-parting, facing topping produce cracking, damaged, significant problem such as peel off, leak, and are tending towards prudent to the promoting the use of of outer heat-preserving building thing of adopting the foamed plastics veneer at present.And whitewash the outer heat-preserving building thing of thermal insulation mortar, have these problems equally, and aspect the increasing degree of heat-insulating property, very limited, be difficult to satisfy the requirement of building energy saving rate 50%, more be difficult to satisfy the requirement of building energy saving rate 65%.This causes beginning the attention to the self-heat conserving building research, and at present in many areas in Jiangsu Province, the research of the energy-conservation brick building thing of sludge fly ash is just in the ascendant.But because the average coefficient of thermal conductivity of energy-conservation brick of energy-conservation brick or energy-saving building blocks, particularly load-bearing or building block is difficult to less than 0.35W/mK, this causes the building energy saving rate of self-heat conserving building to be difficult to surmount significantly the critical point of building energy saving rate 50%.
And country has determined, from 2010, in China, area with good conditionsi all will be promoted building energy saving rate and be reached 65%.Thus,, almost had only an approach of the outer heat-preserving building of employing at the building field of building energy saving rate 65%!
Is does but the insulation layer quality problems of outer heat-preserving building, that how about the insulation life problem thoroughly solve close?
So far, also not making us satisfied, complete fully relieved scheme comes out of the stove.Even national standard stipulates that also only need guarantee 20 years the application life of outer heat-preserving building insulation layer.In addition more common situation is after outer heat-preserving building only uses several years, more than ten years, a series of crack, comes off, leaks, falls problem such as ceramic tile and just emerge in an endless stream, cause a lot of lawsuits of tangling,------
The building energy conservation situation of China allows of no optimist very much in this case!
So, should adopt the heat preserving mode of what pattern actually, improve the building energy saving rate of China's building?
Does the heat-preserving building form address this problem in can adopting?
The wall body structure of safeguarding of interior heat-preserving building is easy to the encroached water steam, and how does the hard nut to crack of produce freeze injury, dewfall, going mouldy solve?
I have proposed out a kind of low-E air heat insulating layer (3) that is provided with the metal sheet paper tinsel as middle low-E layer or attached formula low-E layer No. 200810181801.7, Chinese patent application in " having low-E air thermal preservation structure maintenance member and related building material " literary composition.

Illustrate:
Safeguarding body (1) shown in the accompanying drawing 1, is the bight that is positioned at building, belongs to the corner of exterior wall, position herein, and the two sides body of wall all is provided with inner thermal insulating layer (4), has represented also that here inner thermal insulating layer (4) turns back and ways of connecting a kind of of body of wall corner.
At the window opening place that safeguards body of wall, exterior window trim (5) has carried out the edge sealing sealing to inner thermal insulating layer.
The inside of decoration panel (6) is meant that this decorative board is to safeguarding body of wall, indoor one side dorsad.
Decoration panel (6) is the sheet material or the composite veneer material of gypsum plank or Thistle board or other inorganic or organic material.
Zero permeable formation or less permeable layer (9) can use and be thinned to the thick aluminium foil of several decimillimeters, and this can be more cheap.Aluminium foil preferably adopts rustproof aluminum alloy, also can use the composite membrane or the composite plate of aluminium foil and plastics or paper, can also use the plastic foil or the composite plastic film of hypotonicity.Composite veneer can be selected aluminium-plastic panel for use.Adopt aluminium-plastic panel, can save aluminium foil or zero permeable formation or less permeable layer (9).
Zero permeable formation is meant that its barrier layer adopts this zero penetration material of metal forming to make, but its edge, still unavoidably infiltration gas leakage of seam crossing, thereby its essence still is the less permeable layer of aqueous vapor.
The composite plate that lining pastes aluminium foil comprises the aluminium foil gypsum plank, can as gypsum plank with self-tapping screw fastening be fixed on keel layer (7) above, with respect to aluminium foil, composite plate is a hardboard, can fill up the soft sealing strip band at edge joint position.
Zero permeable formation or less permeable layer (9) are if when adopting smooth aluminium foil or aluminum-plastic composite membrane, not only stop the function of vapor permeation first-class, the performance of its low-E also is the most best, and it can be used as the high efficiency low-E layer of LOW-E air heat insulating layer, reaches multiduty purpose.
Zero permeable formation or less permeable layer (9) are if adopt aluminium foil or aluminum-plastic composite membrane, and its quality softness is difficult to locate without foundation.Can adopt ∏ type air gun rifle nail, (aluminium foil is all big several centimetres than gypsum plank in the size of length and width both direction with the aluminium foil that leaves overlapped leeway, edge.), the pointwise nailing, nail is installed gypsum plank or decoration panel (6) then and is put in place on keel layer (7), adopt self-tapping screw with its fastening tightly be fixed on keel layer (7) above.In this process, each piece aluminium foil of zero permeable formation or less permeable layer (9) or composite membrane joins mutually and piece is airtight well or seal.Thereby make (9) become the zero permeable formation or the less permeable layer of real steam.
For making decorative panel and safeguard that body of wall (1), keel layer (7) or (13) etc. are connected reliably, the life-span is permanent, fastening connection pieces such as tapping screw, air gun rifle nail, swell fixture are to adopt stainless steel part or galvanized part for well whole or in part.
In addition, also need carry out knuckle, the connection work of zero permeable formation or less permeable layer (9) in the corner junction of adjacent two interior heat preservation maintenance bodies; And the peripheral impermeable work of edge sealing of locating to carry out zero permeable formation or less permeable layer (9) around every inner thermal insulating layer (4).The impermeable method of edge sealing has the methods such as putty or weather strip caulked, edge sealing bar (comprise and adopt exterior window trim (5), door pocket) compacting, bonding agent be bonding that adopt.
This shows, inner thermal insulating layer of the present invention prevent that steam to the method for safeguarding body of wall infiltration, being the method for fighting against the enemy on the frontier:
This is that a kind of very thorough, very reliable steam that prevents is invaded the method and measure of safeguarding body of wall.
Zero permeable formation or less permeable layer (9) allow a small amount of or micro-leakage, but it are few more good more to control air leakage at the edge or overlapping junction.
Its zero permeable formation or less permeable layer (9) are as the trapping layer of vapor permeation, and its position is positioned at safeguards the most close indoor place of body of wall, and it is from gypsum plank or other facing plate of one centimetre of thickness of a room air alternating floor.
This will significantly reduce or stop, and heat preservation maintenance wall is subjected to indoor vapor permeation in this, and is safeguarding that body of wall is inner and safeguarding that surface of wall produces freeze injury, dewfall, the possibility of the harm of going mouldy.Thereby the critical defect of key, the essence of heat-preserving building in fundamentally overcoming.
Inner thermal insulating layer (4) has decoration panel (6), zero permeable formation or less permeable layer (9), keel layer (7) and the insulation layer (8) in the faced chamber in turn.
Shown in accompanying drawing 1,2, the air layer that comprises in the aluminium foil layer of zero permeable formation or less permeable layer (9) and the keel layer (7) (going up air layer (16)) has been formed the hollow LOW-E insulation construction of one deck.This one deck keel layer thickness should according to the principle and the practice of LOW-E air thermal preservation structure, surpass 2 centimetres about 2 centimetres, the thermal resistance value that is increased is very limited.2 centimetres air layer according to the smooth bright degree and the antirust degree of aluminium foil, can make the thermal resistance value of the hollow LOW-E insulation construction of this layer layer reach about 0.6m2.k/W or higher.Aluminium foil or clad aluminum foil should adopt the rustproof aluminum alloy material, and clad aluminum foil should be the aluminum foil metal face towards the one side of keel layer (7).
Insulation layer (8) is arranged on the insulation layer between each keel of second layer keel layer (13), and this layer keel should be selected steel joist for use.So as to reduce consumption of wood as far as possible, reduce the house inflammability, improve its anti-flammability.Steel joist is not moisture-sensitive distortion also, can improve the stability in use or the planarization attractive in appearance of inner thermal insulating layer of the present invention (4) greatly.
Uses that can superpose of insulation layer (8) and the hollow LOW-E insulation construction of first floor layer, the one deck in also can removing wherein, use becomes the individual layer insulation construction separately.But change configuration howsoever, zero permeable formation or less permeable layer (9) must be set.
Insulation layer (8) is light-weight thermal insulation material layer of rock cotton board felt, glass wool board felt, flame-retarded foamed plastic and so on or the hollow LOW-E insulation construction that is made of middle aluminium foil layer (14) and air layer or plants hollow LOW-E insulation construction thus and plant the light-weight thermal insulation material layer overlapping compound insulation structure of being arranged to up and down therewith;
Insulation layer (8) is if adopt light-weight thermal insulation material layer or plant the light-weight thermal insulation material layer overlapping compound insulation structure of being arranged to up and down therewith by hollow LOW-E insulation construction, and its thickness should substantially exceed 2 centimetres.Different with simple hollow LOW-E insulation construction, along with thickness increases, its thermal resistance value also will increase pro rata greatly.For this reason, adopt cushion block (10), suitably bed hedgehopping keel layer (13).
The light-weight thermal insulation material layer of rock cotton board felt, glass wool board felt, flame-retarded foamed plastic and so on can attach one deck aluminium foil towards the one side of air.Do the heat-insulating property that helps damp proof insulation, polishing external surface and improve the hollow LOW-E insulation construction adjacent like this with it.
Because the insulating efficiency of hollow LOW-E insulation construction or light material insulation layer is high, its coefficient of thermal conductivity reaches about 0.03 to 0.04W/m.k, and inner thermal insulating layer (4) can and should be done thinlyyer; Comprise decorative panel, when the gross thickness of inner thermal insulating layer (4) reaches 5 centimetres of left and right sides; Its thermal resistance value can reach 1.2m 2.k/W about, add and safeguard that wall total thermal resistance can reach 2m 2.k/W about, this building that has enough satisfied building energy saving rate 70% is to safeguarding the requirement of body of wall thermal technology heat-insulating property.No matter be hollow LOW-E insulation construction or light material insulation layer or their stack compound insulation structure, its cost is all very cheap, only needs about 50 to 80 yuan/m2.
So cost is identical with the outer insulation construction cost of safeguarding body of wall.
But, consider that it is a kind of internal insulation structure that has overcome key essence defective, its application life can be permanent equally with building, and its maintenance and repair can carry out among a small circle in the part, and only need carry out indoor; It just must shovel to fall to reform unlike outer insulation in maximum 20 years with going to war;
And outer insulation is in case damage, with the very big harm that causes the body of wall freeze injury, leaks, ceramic tile comes off, danger is hurted sb.'s feelings.
The insulation data of mentioned interior heat preservation maintenance wall among the present invention, its heat-insulating property is all more far better than the heat-insulating property of the outer heat-preserving building of the overwhelming majority.The insulation layer of outer insulation construction will be in case thickening will be more prone to damage, and the life-span can be shorter.Then there is not this problem in novel interior insulation of the present invention.
Therefore at its use cost, safety in utilization, application life, heat preservation energy-saving aspect of performance, novel interior heat-preserving building thing of the present invention greatly is better than existing outer heat-preserving building thing.
And its heat-insulating property improves very significantly than self-heat conserving building (mainly being the building that adopts energy-conservation brick, energy-conservation masonry), and the self-heat conserving building is used in multistory building more, and novel interior heat-preserving building of the present invention can be used in small sized multiple story building, highrise building, super highrise building fully.
And, inner thermal insulating layer of the present invention, belong to a kind of decoration decorating structure layer in essence, body of wall is safeguarded in main-body structure, load-bearing for building, at aspects such as resistance to compression, shearing resistance, antidetonations is relatively independent, (when adopting light concrete member, is to correlate relatively only, and its associated, also more weak.) therefore, building of the present invention, safety is fabulous, and the regulation according to relevant norm of construction builds a house earlier, and the back finishing does not need to carry out safety demonstration.This helps simplifying the procedures, starting rapidly of it, promotes fast.
Relation about inner thermal insulating layer (4) and insulation layer (8): when the thickness of insulation layer (8) is zero, illustrates and cancelled this insulation layer (8) and keel layer (13) and cushion block (10); At this moment, inner thermal insulating layer (4) only is the hollow LOW-E insulation construction of individual layer.
In insulation layer (8), when the thickness of light-weight thermal insulation material layer during less than insulation layer (8), insulation layer (8) is made of the lightweight thermal insulation layer and the air layer that paste wall.Aluminium foil layer (14) in the middle of counting in, inner thermal insulating layer (4) is the compound insulation structure of double-deck LOW-E hollow insulating structure+light-weight thermal insulation material layer.
When the thickness of light-weight thermal insulation material layer equaled inner thermal insulating layer (8), inner thermal insulating layer (8) was simple light material insulation layer.Inner thermal insulating layer (4) is the compound insulation structure of individual layer LOW-E hollow insulating structure+light-weight thermal insulation material layer.
When the thickness of light-weight thermal insulation material layer greater than inner thermal insulating layer (8), and when reaching the gross thickness of inner thermal insulating layer (4) (removing the thickness of decorative panel (6)), inner thermal insulating layer (4) becomes simple light material insulation layer.At this moment layer keel that two-layer keel should be united two into one (allow to use cushion block (10).)。Inner thermal insulating layer (4) also has other combining form; But the heat-insulating property of other combining form and the heat-insulating property of above-mentioned various combining forms are similar, do not launch carefully to state at this.
In a word, inner thermal insulating layer various informative can be satisfied various different needs, also is an advantageous characteristic of the present invention.
Connect the seam crossing knuckle or adopting aluminium foil strip and the zero permeable formation on both sides or the method that less permeable layer (9) is fitted and connected sealing, be similar to when adopting gypsum plank to carry out interior decoration process: Puttying, stickup anticracking paper tape, brush interior wall coating material at the place, corner; Only will paste the anticracking paper tape, make into to attaching aluminium foil strip.
Below the problem that is specifically related to of heat-preserving building thing in novel and solution, scheme are carried out concrete narration.
The design principles of inner thermal insulating layer and zero permeable formation or less permeable layer (9): the local area that this is set to, all to go to be set to, do not need to be set to local area, just do not go as far as possible to be provided with: specifically: the body of wall (1) of safeguarding towards external environment should be provided with inner thermal insulating layer and zero permeable formation or less permeable layer (9).The other parts of building as the interior parts such as body of wall, enclosed balcony, enclosed stairwell of safeguarding, then are not provided with inner thermal insulating layer and zero permeable formation or less permeable layer (9), perhaps only take insulation measure more poor, that come down a bit.
Illustrate: this wherein has exception, promptly near the intersection of these two kinds of local areas, is not set to inner thermal insulating layer or takes other to be incubated the interior body of wall of safeguarding of measure, should take the insulation measure and the impermeable measure of steam that add.
The concrete beam of this intersection, post member, still not a kind of stressed carrying node also is node, or a kind of aqueous vapor movement node in safeguarding body of wall of the motion of a kind of temperature difference hot-fluid.Can be referred to as the cold bridge node to concrete beam, post member and the body of wall of safeguarding nearby thereof.
We should be noted that: the aqueous vapor characteristics of motion of cold bridge node and near zone thereof and freeze injury dewfall harming rule, and comparatively complicated, comparatively serious.Though according to observation and use experience to existing masonry, concrete, concrete combination construction, as long as the building of these types is correct design, no matter be generally to safeguard body of wall,, all be the harm that to resist or to get rid of freeze injury, dewfall, go mouldy still at the cold bridge node region.
But we it should further be appreciated that, lifting along with interior thermal insulation house building energy saving rate, particularly of the present invention novel in the room of heat-preserving building, its heat-insulating property improves greatly, the indoor serviceability temperature in winter of building will obviously promote, and the partial pressure of indoor steam also will significantly improve, thereby, safeguard body of wall outward at cold bridge node place, the possibility of suffer freeze injury, dewfall, going mouldy also can correspondingly increase.Thereby to the interior body of wall of safeguarding of the cold bridge node in house of the present invention and the part closed on it, should be according to the natural conditions situation difference of locality, according to safeguarding that body of wall uses the difference of material, the difference of present position under construction, adopt additional, suitable, insulation targetedly, damp proof insulation, antifreezing measures.
These measures comprise: the external surface at the concrete component of cold bridge node region adopts local outer insulation insulation layer; Inwardly safeguard wall direction at the cold bridge node region, in right amount extension inner thermal insulating layer (4); The cold bridge node region is carried out all or part of material substitution; To the zone that has a strong impact on of cold bridge, paste insulation belt or whitewash heat-insulation mortar bed (for example light heat-insulation mortar, bead thermal insulation mortar etc.); Near indoor junction of safeguarding body of wall and cold bridge node or junction the interior suitable position of safeguarding on the body of wall is brushed impermeable coating, scrapes impermeable putty, whitewashes or build by laying bricks or stones impermeable mortar, adopts impermeable building block (fragment of brick) or is taked other impermeable measure.These measures may be used alone, can also be used in combination.
Why not need to be set to the local area of inner thermal insulating layer, just to go scarcely to be provided with? done two big benefits like this:
1, reduces cost and the additional trouble that inner thermal insulating layer is set;
2, utilize the big thermal inertia that indoor wall had that inner thermal insulating layer is not set, increase the heat capacity or the thermal inertia in room, place,
So that improve the heat stability in this room.
With four embodiment described below, above-mentioned additional heat-preserving anti-freezing measure is specifically described.
Adopt the interior heat-preserving building thing of local outer insulation insulation layer at the external surface of the concrete component of cold bridge node region, it is characterized in that:
A, building safeguard that outward the beam of body of wall, post concrete component (3) adopt general concrete constructions;
