Description

A kind of cast-in-placely build prefabricated exempting from and dismantle overall assembling insulation exterior sheathing assembly structure
Technical field
The invention belongs to external wall technical field, particularly relate to and a kind of cast-in-placely build prefabricated exempting from and dismantle overall assembling insulation exterior sheathing assembly structure.
Background technology
The compulsory execution of building energy-saving standard and city management are to the strict management and control of building waste and construction noise.
Traditional shear wall construction is after reinforcing bar Peng has pricked, workman installs outer, interior masterplate and support system respectively on scaffolding platform and floor, inner and outer template is at inner support (being generally fixed on reinforcing cage with wall thickness equal length reinforcing bar) and split bolt or under the acting in conjunction of drawing band iron, form concrete placings cavity, after concrete reaches strength of mould stripping, remove masterplate and support.
At present, in order to reach power conservation requirement, newly-built concrete shear wall external wall all needs the structure of insulation layer, the scheme that prior art solves the problem of insulation mainly contains two kinds, one is be placed on inside exterior sheathing with the adiabator plate with gauze wire cloth, be combined with concrete wall by plugging wire during concrete placings, after form removal, plaster, make decoration of exterior wall; Two is that concrete main body is first constructed, after paste warming plate, screening, nailing reinforce after, do wall decoration.These two kinds of schemes all need again scaffolding or suspension bracket, plaster, the wet trade such as coating, there is high-altitude application and disaster hidden-trouble, the quality accident that insulation layer comes off also once occurred.There is reality that is long in time limit, that have high input.
A kind of precast facade formwork structure system and the construction method thereof with heat insulation function are disclosed in prior art, number of patent application: 201510436301.3; Precast concrete outer wall template is proposed, namely precast concrete outer wall template is comprised, the inner side of precast concrete outer wall template is fixed with insulation layer, cast-in-place shear wall has been built in the inner side of insulation layer, reach after desirable strength until concrete and remove inner formword, form cast-in-place shear wall, form the external wall system containing precast concrete outer wall template, insulation layer, cast-in-place shear wall.But the intensity depending merely on precast concrete outer wall template and insulation layer when implementing cannot bear at all concreting deadweight and when vibrating to the lateral pressure of template, only rely on split bolt to be inadequate, be easy to cause the problems such as swollen mould; Build in time in addition shaping after, to durability, fastness test, insulation layer bears deadweight and the weight of precast concrete outer wall template at all, and then causes and come off; Its main cause is that insulation layer and walls concrete are directly built shaping, and first insulation layer mutability under comparatively hightension effect, causes and occur hollowing with walls concrete bonding place; Two kinds of material insulation layers and concrete bonding are not fitted, and its adhesion stress is also relatively poor, does not reach the object of expection at all, so implement this technology cannot practice and extension, equally, also there is this problem in precast concrete outer wall template and insulation layer junction.

(4), by outer mould bases 500 hoisted in position of precast facade insulation, and support fixing, install inner formword 100 in the inner side of wall steel bar, inner formword installs employing prior art, does not repeat at this; Again outer for precast facade insulation mould bases 400 is passed through the pre-stressed joint of split bolt assembly with inner formword 100; Described split bolt assembly adopts prior art, described split bolt assembly comprises the wall bushing running through wall steel bar, the precast facade outer mould bases of insulation and inner formword, be installed on the pretension bolt in wall bushing, inner formword is stretched out in one end of described pretension bolt, the other end of pretension bolt stretches out the pretension crossbeam on adventitia frame, is fitted with pre-load nut respectively at the two ends of pretension bolt; Adjustment precast monolithic assembling insulation exterior sheathing is fixedly mounted with the second locking nut 724 of connector; Then the verticality adjusting device 512 outside the outer mould bases of precast facade insulation is adjusted, the verticality of the outer mould bases of adjustment precast facade insulation, after adjustment is vertical, being incubated outer mould bases according to adjustment precast facade is that benchmark adjusts split bolt assembly again, makes precast facade be incubated the pre-stressed joint parallel with inner formword of outer mould bases;
(5), concreting in the wall steel bar be incubated between exterior sheathing is assembled to inner formword and precast monolithic;
(6), until concrete reach after desirable strength and remove inner formword and the outer mould bases of precast facade insulation, form cast-in-place shear wall, form the external wall system containing precast monolithic assembling insulation exterior sheathing, cast-in-place shear wall.
The present invention has the following advantages in sum:
1, insulation layer is combined with assembled template component, save the construction of insulation layer secondary, construction wall heat-insulating property can be improved, improve build guality, meet national exterior wall fireproof code requirement, body of wall and Surgery therapy simultaneous construction can be realized simultaneously, and then better for energy-saving and emission-reduction contribute.
2, precast monolithic assembling warming plate adopts composite construction, and namely insulation layer is arranged on the inner side of cement-based mortar outer coversheet, avoids exposing to the weather, and adds the durability of insulation layer.
3, inner formword is set up in the inner side that precast monolithic assembling insulation exterior sheathing is corresponding, again coupling assembling is assembled through inner formword and precast monolithic and be incubated exterior sheathing and be incubated outer mould bases with precast facade and be fixedly connected with, building exterior sheathing and external scaffolding can be saved, improve efficiency of construction, reduce costs, the reduction of erection time.
4, adopt the outer mould bases of precast facade insulation, support powerful concrete deadweight, while can resist produced lateral force of vibrating when building; Solving the problem of prior art exterior sheathing bearing capacity difference, there is the problem of hollowing in the junction of causing because of insulation layer distortion.
5, the connection with concrete wall is improved at precast concrete outer wall template at the connector preset, overcome the shearing force of heat-insulation plate for external deadweight, improve fastness, extend the durability of insulation layer, fundamentally solve exterior wall heat-preserving system and there is cracking, play the quality problems such as drum comes off;
6, the present invention can realize factory normalization production and processing, solves the quality uncontrollability brought of execute-in-place in construction process;
7, the present invention realizes insulation and building same life-span substantially.
In sum, the present invention increases heat-insulating property durability, reduces construction cost, reduction of erection time, saves the construction of insulation layer secondary, can improve construction wall heat-insulating property, improve build guality, meet National Fire design specifications, can reach fire prevention A grade standard.
The above is only to preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
