Description
Technical field
The external heat insulating composite wall that the present invention relates to build, particularly a kind of exterior wall external insulation composite wall body that supporting is arranged.
Background technology
The problem that body of wall energy-saving heat preserving technology exists not only influences the effect of building energy conservation; Influence the low-carbon (LC) social construction; Its safety also influences the safety of people's lives and properties; The fire savety problem of poor that the thin heat-preserving wall of plastering exists has fire to take place when causing various places, and the tragedy that Jing'an District, Shanghai high level that 2010.11.15 shocks the world catches fire has just taken place not long ago! Burn because of the firecracker of setting off fireworks makes the northeast first high Shenyang feudal dynasties ten thousand prosperous CITIC Building insulation layer morning on the lunar New Year's Day in 2011, fire causes heavy losses to society thereupon.Why body of wall energy-saving heat preserving technology fire is continuous, except the quality of materials problem, also because the topping in the macromolecule insulation layer that is easy to the burn outside is too thin, only accompanies the cement polymer mortar of 3～4mm of glass fiber net.
For solving the heat insulating ability and the contradiction of fire savety that exists in the body of wall technology, increase body of wall energy-saving heat preserving effect, applicant is the following body of wall technical patent of proposition successively:
Patent 1: patent No. ZL200410002698.7, the patent that denomination of invention " has support, the anti-seismic heat-preservation combined wall of reinforced concrete external protection is arranged ".
Patent 2: patent No. ZL200610153289.6, the patent of denomination of invention " binding composite heat preservation wall that support is arranged ".
Patent 3: number of patent application 201019185057.2, the patent of denomination of invention " a kind of exterior wall external insulation composite wall body that supporting is arranged ".
1, the combined wall of above-mentioned 3 patents all has a common member: the supporting beam of encorbelmenting, the concrete bearing of the public technology beam of encorbelmenting be inconvenient to construct, influences construction speed, cost height, also inconvenient existing building reducing energy consumption practical applications.
The supporting of patent 1 Liang Weigang that encorbelments supports 2, sees Fig. 2, Fig. 5, Fig. 7 of this patent, is to be supported by the steel that shaped steel or steel plate are welded.Patent 2 is referred to as the concrete bearing beam 2 of encorbelmenting, and sees this patent Figure 27; Patent 3 is referred to as the concrete bearing beam 1-5 that encorbelments, and sees this patent Fig. 2.Accompanying drawing 1 of the present invention is exactly this concrete bearing beam construction figure that encorbelments.
Why patent 1 adopts steel to support, and is because the influence that the stone curtain wall decorating structure is installed.It is current when curtain wall decoration, billboard, anti-theft fence, sunbreaker and thick and heavy ornament are installed on composite thermal-insulating wall; All need shaped steel be penetrated insulation layer and basic unit's body of wall is fixed; The shaped steel of stone curtain wall keel is installed on the shaped steel that penetrates insulation layer, then stone curtain wall is connected with the shaped steel of keel.Because of the topping outside the composite thermal-insulating wall of patent 1 formation is formed, hung the curtain wall on steel supports through reinforcing bar by reinforcing bar, metal lath and plaster, adopt steel to support so receive the influence of stone curtain wall decorating structure.
Curtain wall decoration penetrates the vertical and about 0.8～1.2m of level interval of shaped steel of insulation layer, and shaped steel quantity is many, and section is big, and heat output is many, greatly influences effects of energy saving and emission reduction.A high 80mm, the channel-section steel of wall thickness 5mm, section just reach 12.24cm
2Even only 1 of every square metre of metope, the revised coefficient of thermal conductivity of EPS plate reaches 0.12w/m approximately
2.k, compare 0.05w/m
2.k coefficient of thermal conductivity increase heat transfer 140%! Because supporting, steel conducts heat too much, unfavorable to energy-saving heat preserving, in the combined wall of sealing, be easy to corrosion; Only if take body of wall apart in the future, otherwise can't keep in repair, can not guarantee 50 years durable yearss; Generally should not adopt, so in later patents, all change the concrete bearing beam of encorbelmenting into.
The concrete bearing beam of encorbelmenting is perpendicular to that major structure of construction is provided with, and it is inner fixes with major structure of construction.It is in order to solve following problem that the concrete bearing beam of encorbelmenting is set:
1), the strand of hot bridging of Guttr board that bodies of wall such as sandwich heat preservation, insulation blocks are existed makes the point-like heat bridge, reduces heat bridge and reduces 90% approximately, reduces the passage that heat runs off significantly, increases body of wall energy-saving heat preserving effect.
2), outdoor reinforcing bar is hung in the concrete bearing beam outer end steel plate welding of encorbelmenting; Gauze wire cloth and outdoor reinforcing bar binding form the reinforcing bar of being hung, the curtain wall of metal lath and plaster, depth of plastering 22～30mm; Increase the composite thermal-insulating wall fireproof performance, fire endurance is not less than 1～1.4 hour.
3), the concrete bearing beam of encorbelmenting is set; Reinforcing bar can conveniently be set at the hole to be connected with supporting; Conveniently take the heat-insulating bridge-cut-off measure at door and window hole; Reduce or cancel the passage of door and window hole heat loss, make that the energy-saving heat preserving performance of composite thermal-insulating wall can be considerably beyond the best thin heat-preserving wall of plastering of current energy-saving heat preserving effect.
4), help the combined wall durability.When thick plaster curtain wall topping and insulation layer were bonding, macromolecule adhesive was plastered between topping and the insulation layer in cement mortar, did not receive the ultraviolet ray irradiation, good endurance; And the polymer grout of the thin topping of plastering is directly shone by ultraviolet ray, and durability is bad.
The concrete bearing part of encorbelmenting that beam is and major structure of construction or basic unit's body of wall are fixing of encorbelmenting, but there is following problem in the concrete bearing of the public technology beam of encorbelmenting:
1), no matter to be the cast-in-place installation concrete bearing beam of encorbelmenting, the still prefabricated installation concrete bearing beam of encorbelmenting, construction is all very inconvenient, time-consuming non-material.
On-the-spot formwork is installed the concrete bearing beam of encorbelmenting; The reinforcing bar that supporting is encorbelmented in the beam is anchored in the concrete, and each standard width of a room in an old-style house needs 3 concrete bearings beam of encorbelmenting approximately, and one 10,000 square metres building need punch 1500～1800 approximately; On template, need punch; Inconvenient template is installed, and is time-consuming, destroys bigger to template again.The beam if the precast concrete supporting is encorbelmented needs prefabricated 1500～1800 equally, needs the prefabricated and transportation in place; And need there be the pre-embedded steel slab welding on steel plate and the agent structure rear end; By the concrete bearing beam section 100 * 120mm that encorbelments, consider that the steel plate area of weld seam needs 120 * 140mm, 2 of quantity; Add outer end steel plate 100 * 120mm, three block plate area=0.0456m
2, steel consumption is big, welding capacity is big, and the construction trouble is more infeasible.Therefore, no matter be the cast-in-place installation concrete bearing beam of encorbelmenting, the still prefabricated installation concrete bearing beam of encorbelmenting, construction is all very inconvenient.
2), in existing building reducing energy consumption engineering, use when the external heat insulating composite wall of supporting is arranged, bar planting quantity is many, new-old concrete is difficult to be combined as a whole, and is difficult for guaranteeing workmanship, construction is inconvenient.
2, the concrete bearing cast-in-place inconvenience of beam of encorbelmenting is connected with steel work, and like prefabricated front-end and back-end 2 block plates that also need, steel consumption is big, and prefabricated quantity is big.
The encorbelment problem of beam of concrete bearing becomes the obstacle of the combined wall of promoting the aforementioned invention of applicant; Available other member substitutes the concrete bearing beam of encorbelmenting, and has both played concrete bearing encorbelment beam action, convenient construction again; Do not destroy template, and conveniently be connected with steel work?
2, except that the energy-saving wall technology that the inventor proposes, other energy-saving wall technology be used for fixing the connector rigidity of wire lath in the external protection poor, do not prevent fires, as:
Be provided with wire lath in the topping of glue powder polyphenyl particle energy-saving heat-insulating body technique, being connected with the basic unit body of wall is with the lentor nail wire lath and basic unit's body of wall to be fixed.(it is the plastic sheet of an about 3mm of thickness, the about 30mm of width that these plastics connect bridge to connect bridge with plastics among the provincial standard DB23/1167 of Heilongjiang Province; Two ends have bayonet socket) the benzene plate module and the cast-in-situ concrete that will have a dovetail groove fixes, and these plastics connect bridge and are used for fixing the gauze wire cloth in the thick floated coat of outside 22mm simultaneously.Lentor nail is connected the rigidity of bridge with plastics all bad, benzene plate atrophy when particularly catching fire, and lentor is followed closely the also thawing very soon of plastics that is connected bridge with plastics, the outside danger that topping still can come off of plastering.
This explanation, current these energy-saving heat-insulating body techniques generally do not solve the safety problem of external protection.
3, the technology of energy-saving heat-insulating wall curtain wall decoration installation does not at present solve, and causes the curtain wall decoration fire prevention bad, like CCTV's platform big fire, is exactly the burning of curtain wall inner thermal insulating layer.
For guaranteeing the safety of composite thermal-insulating wall external protection; Satisfy fire safety, be convenient construction, reduction cost, remedy the deficiency of my aforementioned patent; And satisfy the multiple requirement of building to body of wall, a kind of exterior wall external insulation composite wall body that supporting is arranged of the present invention is proposed.
