Description

A kind of flexible heat-insulating composite wall
Technical field
The present invention relates to a kind of composite thermal-insulating wall of building, particularly a kind of flexible heat-insulating composite wall.
Background technology
China widely applies the best EPS plate thin plastering heat-preserving wall of heat insulation effect at present, but it is bad to prevent fires, and durability is bad, and outside finish is dangerous; The U.S., Russian body of wall with the two-layer insulation of three layers of body of wall therebetween, wall is too thick, the waste soil, and be not suitable for the highrise building application.The wooden construction filling insulating wall body is national impracticable timber resource shortage, and wind resistance is bad.
Even be incubated best EPS plate thin plastering heat-preserving wall, because the insulation layer of pasting around door and window hole is much thinner than the body of wall outside, heat runs off many at jamb.Providing the thin heat-preserving wall hole of plastering in " Heilongjiang Province's Residential Buildings Energy 65% design standard " 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 the body of wall mean thermal transmittance approximately near 0.1w/m 2During window-wall ratio 0.5, increase body of wall mean thermal transmittance 0.16w/m 2The 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, and heating area door and window hole heat bridge has a significant impact building energy conservation.For example severe cold area requires the body of wall mean thermal transmittance to be not more than 0.4w/m 2.k the time, dwelling house is because also have the influence of balcony slab heat bridge, and the thermal transmittance of main wall body is about 0.2~0.25w/m 2.k, need the polystyrene board heat-insulatation layer thickness 250~200mm of stickup, be difficult to be accepted, be subjected to resistance in the practical application, influence the realization of national target for energy-saving and emission-reduction at present.All body of wall energy-saving heat preserving technology all do not solve the difficult problem of door and window mouth heat bridge at present.
China makes the exterior wall of frame structure building mostly of gas concrete, light-weight hollow building block made.But these bodies of wall are still too heavy for highrise building, and thermal insulation is bad, fragility is big, and antidetonation is bad.Big for solving the fragility wall weight, be not suitable for problems such as highrise building, widely apply light steel frame body of wall abroad in recent years.
But there is following problem in light steel frame body of wall: body of wall rigidity is poor, resists horizontal wind load and geological process ability, and steel consumption is big, cost is high, complex structure.Light steel frame heat bridge is many, be incubated badly, is building energy conservation, also need glue one deck heat insulating material again outside wall, increases cost again.
For resisting horizontal wind load and geological process, U.S.'s Multiple-story Lightweight Steel dwelling house adopts light steel shear wall, or the steel framed structure that adopts the band right-angled intersection to support, and light steel shear wall is a covering steel sheet on body of wall.For increasing the shock resistance of light steel frame body of wall, the KC system of Japan forms integral wall jointly with shaped steel and sheet material becomes shear wall, to go up wainscot sheathing by the resistance to plucking crab-bolt that connects floor and be connected as a single entity, wallboard and floor will be connected as a single entity complex structure, cost height by shearing bolt.The light steel frame wall thermal insulating of Japan adopts the interior heat preserving mode of spraying polyurethane, and the U.S. is incubated outside doing on the covering steel plate again.These technology complexity of not only constructing, the cost height, and energy-saving heat preserving is too poor.
The essence of light steel frame wall structure is that the skeleton with the wooden frame filled wall is become by flitch and makes the light steel of thin-walled, skeleton spacing 400~600mm, and general every layer be provided with the horizontal steel tie rod in three roads, interior filling mineral cotton.Fiber cement board etc. is made in the plank topping change of wooden frame filled wall, taked other technical measures again, its structure essence is not jumped out the notion of traditional wooden frame filled wall structure.
Owing to reasons such as cost height, light steel frame body of wall is used in China and has been subjected to resistance.
The solution that the outer wall technology of the exterior wall of frame structure building, particularly highrise building does not improve all the time.Do not have perfect body of wall technology to make body of wall have following comprehensive excellent properties simultaneously in the world at present: lightweight, high-efficiency insulated energy-conservation, stress performance comprehensively, antidetonation wind resistance, simple structure, design and construction convenience, outside finish safety, good fireproof, good endurance, cheap.
For addressing the above problem, the inventor of present patent application China propose the patent of invention name be called " inside and outside be provided with reinforcing bar/and the combined wall of metal lath and plaster ", number of patent application is 200710072572.0 patent; Also propose the patent of invention name and be called " a kind of composite component of alkaline-resisting glass fiber net plasterer ", number of patent application is 200910141007.4 patent.The combined wall of these two patents can alleviate wall weight significantly, becomes self heat insulation wall.But there is following problem:
1, the hole topping heat bridge of plastering is unfavorable to energy-saving heat preserving.
The cement mortar topping of plastering in hole is still the passage that heat runs off, and linear thermal transmittance ψ value reaches 0.13~0.15w/m.k.Even the outside, hole paste heat-preserving bar 20~30mm, linear thermal transmittance ψ value also reaches 0.1w/m.k, and is unfavorable to energy-saving heat preserving, is difficult to reach low heat transfer coefficient.
2, do not provide the structure at further reinforcement hole, make the hole be inconvenient to install facilities such as anti-theft fence.
3, sandwich layer construction inconvenience is installed; number of patent application 200910141007.4 patents have provided the combined wall structure at embodiment one; description construction and installation like this after the narration of the structure of embodiment one: " when sandwich layer is constructed for the macromolecule heat insulating material; should on polymer sandwich layer, smear first pass cement mortar or pea gravel concreten topping 8 earlier, see Fig. 3.By interfacial agents topping of plastering 8 and sandwich layer 3 bondings are formed building blocks, building block size so that move is advisable.As the cementing agent between sandwich layer 3 building blocks, build top one deck building block with interfacial agents again by laying bricks or stones ...,, and at any time the slit of seam between the building block is filled and led up with mortar until the body of wall height of needs.……。”。This is the formation building block of plastering on sandwich layer, and the weight of dependence building block or the alkaline-resisting screen cloth that also needs to paste keep the stable of combined wall construction stage.Make the insulation blocks operation but having increased plasters in advance, and move bulk building block inconvenience is installed, the building block inconvenience of higher position particularly is installed; Also require the bonding plane between the building block to coincide, otherwise the centre has the slit can not be bonding, with regard to handy polymer mortar levelling bonding, but the hardening time of polymer mortar is longer, and increases the heat transfer heat bridge, and sandwich layer is installed inconvenient.
Whether can remove or reduce the hole heat bridge, whether the method for quickening fixed installation sandwich layer, convenient construction installation is arranged, how is the door and window mouth further strengthened? the present invention is exactly in order to address this problem.

Because of sandwich layer modulus of elasticity of the present invention is little, so be referred to as the flexible compound heat-preserving wall.
The present invention has taked the heat-insulating bridge-cut-off measure at door and window hole, and to the heating area, particularly the body of wall of severe cold area construction low heat transfer coefficient has important and meaning.
Technique effect of the present invention is:
1, good heat insulation
When EPS plate different-thickness, the flexible heat-insulating composite wall mean thermal transmittance reference table of hole heat insulation break bridge structure see attached list (this table accounts for combined wall area 40% by the beam column area, and beam column outside EPS plate calculates than flexible body of wall attenuate 60mm).If there is the floated coat heat bridge at the hole, the flexible heat-insulating composite wall mean thermal transmittance will increase about 0.1~0.2w/m than data in the table 2Influence quite greatly, the ratio that window areas accounts for wall area is big more, and the body of wall mean thermal transmittance that heat bridge increases the more.By subordinate list as seen, the flexible heat-insulating composite wall of hole heat insulation break bridge is easy to reach low heat transfer coefficient, and for example the about 300mm of combined wall gross thickness of sandwich layer EPS plate 240mm thickness is the high heat-preserving wall of a suitable depth.
The flexible heat-insulating composite wall mean thermal transmittance reference table of subordinate list hole heat insulation break bridge structure
Illustrate: 1, housing construction contains the balcony slab heat bridge that is incubated EPS plate 100mm up and down, increases 0.05w/m than numerical value in the table approximately 2.k (account for body of wall length 50%) by balcony length.
2, subordinate list is pressed EPS plate coefficient of thermal conductivity 0.05w/m.k, and EPS plate thickness attenuate 60mm calculates in the EPS thickness ratio framework of the beam column outside.
3, the EPS plate average thickness of flexible body of wall is EPS plate thickness in the framework-(20~30) mm (with the window-wall ratio difference).
2, construction install convenience
The job practices of the quick fixed installation sandwich layer that the present invention proposes, construction install convenience makes flexible body of wall have the construction feasibility.
3, provide the structure at further reinforcement hole.
A kind of flexible advantage of protecting combined wall of the present invention is:
1, have outstanding safety of structure:
1) the out-of-plane anti-bending strength is good.
The product that flexible heat-insulating composite wall own wt of the present invention multiply by the horizontal earthquake influence coefficient generally is far smaller than the wind load combined value, is often to meet 2 times of geological process modular design value as the Beijing area approximately by the flexible body of wall of wind load modular design value design, body of wall will not take place during earthquake destroy and collapse.The degree of safety of flexible heat-insulating composite wall when earthquake is greater than the degree of safety of agent structure.When flexible heat-insulating composite wall is macromolecule heat insulating material such as EPS plate at sandwich layer, but sandwich layer EPS plate earthquake energy turns earthquake kinetic energy into potential energy, defeats a force with a tenderness, not only combined wall inherently safe, and favourable major structure of construction antidetonation.
2) combined wall rigidity is big, satisfies the serviceability limit state designing requirement.
Under both sides cement mortar floated coat and the sandwich layer strong bond condition, core layer thickness is 120mm, contain the both sides gross thickness of plastering is the combined wall of 180mm, is C15 by the topping label of plastering, and its cross section bending rigidity is 7.52 * 10 12N-mm 2/ m, with thickness 150mm, cross section bending rigidity and 7.875 * 10 12N-mm 2The C25 concrete wall of/m are suitable; Core layer thickness is 180mm, contain the both sides gross thickness of plastering is the combined wall of 240mm, and the cross section bending rigidity is 14.65 * 10 12N-mm 2/ m, greater than thickness 180mm, the cross section bending rigidity is 13.61 * 10 12N-mm 2The C25 concrete wall of/m are seen " calculated description one ".General comfortable thickness of wall body is not less than 200mm, so the combined wall good rigidity that both sides have net to plaster satisfies the serviceability limit state designing requirement.
3) combined wall of the present invention sockets by anchor bar and post, and the gauze wire cloth in the topping of plastering has anti-shearing bearing capacity, and the restriction building is in horizontal movement.
Disregard the anti-shearing bearing capacity of flexible heat-insulating composite wall gauze wire cloth in frame plane exterior rendering topping; the indoor plastering layer anti-shearing bearing capacity of combined wall in frame plane that 3m is high is that 2~7t/m is (with the different anti-shearing bearing capacity differences of gauze wire cloth specification; see calculated description two); form light-duty composite shear wall, light-duty composite shear wall both can be used for exterior wall and also can be used for interior wall.As long as mortar cover and gauze wire cloth and anchor bar bond, combined wall just has anti-shearing bearing capacity in wall plane, and promptly light-duty combined wall can become shear wall.When the filled wall of frame construction all adopted combined wall of the present invention, the anti-shearing bearing capacity that whole building increases was very considerable.
Though flexible heat-insulating composite wall steel content of the present invention is few, be about 2.5~3kg/m by wall area calculating 2(comprising gauze wire cloth); but the reinforcing bar of combined wall and gauze wire cloth or alkaline-resisting screen cloth are positioned at inside and outside both sides cement mortar or pea gravel concreten topping; and with the agent structure anchor connection; contain the plaster topping and the very big cross section bending resistance resistance moment of sandwich layer strong bond formation of reinforcing bar and gauze wire cloth, can give full play to the high advantages of tensile strength such as steel, gauze wire cloth.And the great deal of steel of light steel frame body of wall is positioned at the wall section middle part, do not have pea gravel concreten or cement mortar and steel co-operation, the cross section bending resistance resistance moment that skeleton forms is very little, so steel using amount is many, but the antidetonation wind loading rating is still poor, and light steel frame body of wall is not given full play to the advantage of various materials.
4), the flexible heat-insulating composite wall of on major structure of construction, taking root, when earthquake, will not come off and hurt sb.'s feelings.
Flexible heat-insulating composite wall and other various filled walls (as figuline building blocks wall, aerated-block wall) ratio has more outstanding safety of structure.
2, energy-saving heat preserving is good.
Flexible heat-insulating composite wall of the present invention is exactly a self heat insulation wall, its heat bridge is than light steel frame body of wall much less, even there is the cement mortar heat bridge at embodiment 11 holes, by preceding page or leaf subordinate list as seen, when EPS plate thickness 150mm, flexible body of wall mean thermal transmittance also can reach 0.5~0.6w/m 2.k, be the energy-saving wall that can satisfy severe cold area energy-conservation 50% and North China energy-conservation 65%; Flexible heat-insulating composite wall of the present invention is taked heat-insulating bridge-cut-off at the hole, further just becomes energy-efficient low energy consumption body of wall.
The out-of-plane anti-bending bearing capacity of flexible heat-insulating composite wall of the present invention, planar anti-shearing bearing capacity, consume the ability and the efficient energy-saving heat-preservation performance of geological process, all be a lot of light steel frame body of wall of steel content with it cannot than, current especially other body of wall technology is not available.But the light steel frame wall cost that a kind of flexible heat-insulating composite wall cost of the present invention only is identical heat insulation effect 25~30%! Reduce the external wall of high-rise building cost significantly.
The economy of a kind of flexible heat-insulating composite wall of the present invention, thermal and insulating performance, seismic wind resistance, minimizing construction stage energy consumption have all surpassed all bodies of wall that comprise light steel frame body of wall.
Reinforcing bar and netted tensile materials, concrete (cement mortar that has comprised the concrete effect), bearing masonry are to belong to the stressed material of building structure; Macromolecule heat insulating material, chemical adhesive are to belong to the building function material.The repairing formula that all belongs on former non-insulation fragility body of wall of existing various wall thermal insulation technologies is incubated, so there is following problem: perhaps heat bridge is too many, for example sandwich heat preserving wall body or insulation blocks body of wall; Perhaps dangerous, have as pasting the thin heat-preserving wall of plastering of macromolecule insulation layer that fire prevention is dangerous, outside finish is dangerous, and these bodies of wall are because of too heavy all unfavorable to antidetonation; And light steel frame body of wall is unreasonable to the combination of structure stress material and building function material, so there are aforementioned problems.
The characteristic of every kind of constructional materials all has its limitation, having energy-conservation, as to economize a series of excellent properties such as ground, wall change, antidetonation wind resistance advanced body of wall technology is not that the novel wall material of only producing in factory just can solve, must be optimized combination to various materials, give full play to the characteristic of different constructional materialss, could satisfy the various requirement of contemporary mankind simultaneously body of wall.The body of wall technology is a system engineering, needs the cooperation of multi-subject knowledge, research body of wall Technology Need interdiscipline, cross-cutting comprehensive study.
A kind of flexible heat-insulating composite wall of the present invention is multi-subject knowledges such as building complex, structure, building physics, building thermal technique, chemical adhesive, metallography, break through that notion that traditional body of wall forms puts forward, the present invention has overturned the notion that traditional body of wall forms.
The present invention can satisfy the many requirement of contemporary mankind to body of wall simultaneously: lightweight, heat preservation energy-saving, province ground, antidetonation wind resistance, outside finish safety, good fireproof, good endurance, cheap, easy construction.The present invention is to the building aseismicity wind resistance, and is significant to the reply Global climate change.
