Description

A kind of building heat preservation combined wall
Technical field
The present invention relates to a kind of building heat preservation combined wall.
Background technology
One, some energy-saving wall technology are come the wire lath in fixing insulation layer exterior rendering topping with connector, and these connector rigidity are poor, do not prevent fires, or heat bridge is too many, as:
Be provided with wire lath in the topping of glue powder polyphenyl particle energy-saving heat-insulating body technique, with the bloated nail of lentor wire lath and basic unit's body of wall fixed when being connected with the building-block wall.
(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 the outside 22mm of benzene plate simultaneously.
It is all bad that lentor is followed closely the rigidity that is connected bridge with plastics, when insulation layer is thicker, is difficult to satisfy the requirement of secure fixation, benzene plate atrophy when catching fire, and the lentor nail is connected bridge with plastics plastics also melt very soon, and the outer protection layer is plastered to come off and still can be caused danger.
Steel wire net rack cement filled board is every square metre has 200 Φ, 2 cross one another oblique rollering steel silks, with the weight of oblique rollering steel silk fixed outer cement mortar floated coat, increases and conducts heat about 60%.
Two, applicant has proposed the patent of following 4 bodies of wall technology, and the combined wall of these 4 patents all has a common member: support the beam of encorbelmenting.There are problems in the disclosed supporting beam of encorbelmenting.
Patent 1, patent No. ZL200410002698.7, denomination of invention is the patent of " support is arranged, the anti-seismic heat-preservation combined wall of reinforced concrete external protection is arranged ".
Patent 2, number of patent application 200710167871.2, denomination of invention for " both sides be provided with reinforcing bar/with the combined wall of metal net plaster ", the patent of publication number CN101168977A.
Patent 3, number of patent application are 200910141007, and denomination of invention is " a kind of composite component of alkaline-resisting glass fiber net plasterer ", the patent of publication number CN101570981A.
Patent 4, number of patent application 201010253687.1, denomination of invention is " combined wall that a kind of both sides have net to plaster ", the patent of publication number CN101936046A.
Patent 1 is provided with steel and supports 2; Patent 2 is concrete hanging top supporting member 1-5; Patent 3 is the concrete hanging top supporting member, sees Instructions Page 10 the 7th row; Patent 4 is for supporting the beam spare 1-5 that encorbelments, and what this patent Figure 10, Figure 12 provided is concrete hanging top supporting member structure.
The topping in the composite thermal-insulating wall outside of patent 1 is formed by reinforcing bar, metal lath and plaster, hangs the curtain wall of plastering on steel supports through reinforcing bar.Why at that time applicant adopts steel to support in invention, is because the influence that the stone curtain wall decorating structure is installed.Shaped steel all was to penetrate insulation layer and basic unit's body of wall or fix with major structure of construction when stone curtain wall was installed; The shaped steel of stone curtain wall keel is fixed with the shaped steel that penetrates insulation layer again; Then stone curtain wall is connected with keel, adopts steel to support so receive the influence of stone curtain wall decorating structure.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; Vertical and the about 0.8~1.2m of level interval of shaped steel, shaped steel quantity is many, and section is big; 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 just reach 0.12w/m approximately 2.k, compare 0.05w/m 2.k coefficient of thermal conductivity increase heat transfer 140%!
The steel of patent 1 usefulness shaped steel or steel plate welding supports the waste steel, and steel support increase is conducted heat too many, in the combined wall of sealing, is difficult to have effective anticorrosive measure; Can't keep in repair in the future; Can not guarantee 50 years durable yearss, steel supports and is not suitable for the heating area, is not suitable for severe cold area especially; Generally should not adopt, so follow-up patent 2, patent 3 and patent 4 all are to adopt the concrete bearing beam of encorbelmenting.
Fig. 9 of the present invention is exactly the concrete bearing beam construction figure that encorbelments, and concrete bearing is set encorbelments beam except avoiding shortcoming that steel supports, also in order to solve following problem:
1), the concrete bearing beam of encorbelmenting hangs outdoor reinforcing bar, 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 increases the composite thermal-insulating wall fireproof performance, satisfies the fire endurance requirement.
2), 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, it is about 90% to reduce heat bridge, reduces the passage that heat runs off significantly, increases body of wall energy-saving heat preserving effect.
3), because the hole is provided with reinforcing bar; 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 high-molecular cement polymer mortar of the thin topping of plastering is directly shone by ultraviolet ray, and durability is bad.
There is following problem in beam but concrete bearing is encorbelmented:
1), on-the-spot formwork installs the concrete bearing beam of encorbelmenting, the reinforcing bar that supporting is encorbelmented in the beam is anchored in the concrete, on template, need punch, inconvenient template is installed, and destroys bigger, time-consuming to template.The beam if the precast concrete supporting is encorbelmented; Prefabricated amount too big (each standard width of a room in an old-style house average needs 3, and 10,000 square metres building needs 1500~1800 approximately, 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; Steel consumption is big, welding capacity is big, and the construction trouble is more infeasible.Therefore, no matter be cast-in-place installation or the prefabricated installation concrete bearing beam of encorbelmenting, construction is all very inconvenient, and this becomes and adopts the encorbelment obstacle of beam of concrete bearing.
2), concrete bearing is encorbelmented, and beam is inconvenient to be connected with steel work.
Does available other member substitute the concrete bearing beam of encorbelmenting, and has both played the concrete bearing beam action of encorbelmenting, and convenient construction does not destroy template again, and conveniently is connected with steel work?
Three, the technology of energy-saving heat-insulating wall curtain wall decoration installation does not at present solve, and the curtain wall decoration fire prevention is bad, catches fire like CCTV's building big fire, ten thousand prosperous restaurants, Shenyang, is exactly the burning of curtain wall inner thermal insulating layer.
Summary of the invention
