Description

Prefabricated exempt to dismantle overall assembling insulation exterior sheathing and build connector with shear wall is cast-in-place
Technical field
This utility model belongs to external wall technical field, and more particularly to a kind of prefabricated to exempt to dismantle overall assembling insulation outer Template builds connector with shear wall is cast-in-place.
Background technology
The compulsory execution of the building energy-saving standard and city management strict management and control to building waste and construction noise.
Traditional shear wall construction is that workman installs on the landing stage of scaffold and floor respectively after the completion of reinforcing bar is pricked Outward, interior masterplate and support system, inner and outer template is in inner support (being typically fixed on steel reinforcement cage with wall thickness equal length reinforcing bar) and right Draw bolt or to drawing under the collective effect of 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 is both needed to the construction of heat-insulation layer, existing skill Art solves the problems, such as that the scheme being incubated mainly has two kinds, and one is to be placed on inside exterior sheathing with the adiabator plate with steel wire, 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 guarantor Warm plate, after screening, nailing are reinforced, makees wall decoration.This two kinds of schemes are both needed to again scaffolding or suspension bracket, plaster, apply , there is high-altitude application and disaster hidden-trouble in the wet trades such as material, the quality accident that heat-insulation layer comes off also once occurred.There is long in time limit, input Big reality.
A kind of precast facade formwork structure system with heat insulation function and its construction method, patent disclosed in prior art Application number:201510436301.3;Propose precast concrete outer wall template, that is, include precast concrete outer wall template, prefabricated mixed The inner side of solidifying soil outer wall template is fixed with heat-insulation layer, and the inner side of heat-insulation layer has poured cast-in-place shear wall, treats that concrete reaches required Remove inner template after intensity, form cast-in-place shear wall, form outer wall template containing precast concrete, heat-insulation layer, cast-in-place shear wall External wall system.But the intensity depending merely on precast concrete outer wall template and heat-insulation layer when implementing cannot be born and be poured coagulation at all Soil deadweight and when vibrating the lateral pressure to template, relying solely on split bolt is inadequate it is easy to cause swollen mould etc. to ask Topic;In addition, after pouring molding in time, from the point of view of durability, fastness are tested, heat-insulation layer bears deadweight and precast concrete at all The weight of outer wall template, in turn results in and comes off;It main reason is that heat-insulation layer and walls concrete directly pour molding, first Heat-insulation layer changeableness under larger tension force effect, causes hollowing with walls concrete bonding place;Two kinds of material heat-insulation layers with Boning of concrete is not fitted, and its cohesive force is also relatively poor, does not reach expected purpose at all, and then implements this technology no Method practice and extension, equally, precast concrete outer wall template and heat-insulation layer junction there is also this problem.

3rd, set up inner template in the prefabricated overall assembling insulation corresponding inner side of exterior sheathing, then coupling assembly is passed through inner template It is incubated outer mould bases and is fixedly connected with prefabricated overall assembling insulation exterior sheathing and precast facade, building exterior sheathing and outer foot can be saved Hand cradle, improves efficiency of construction, reduces cost, reduction of erection time.
4th, adopt precast facade to be incubated outer mould bases, to support the deadweight of powerful concrete, can resist simultaneously and pour When vibrate produced side force;Solve the problems, such as that prior art exterior sheathing bearing capacity is poor, cause because of heat-insulation layer deformation The problem of hollowing in junction.
5th, improve the connection with concrete wall in precast concrete outer wall template in default connector, overcome external thermal insulation The shearing force of plate deadweight, improves fastness, extends the durability of heat-insulation layer, fundamentally solves exterior wall heat-preserving system presence and opens Split, play drum and the quality problems such as come off;
6th, this utility model can realize factory normalization production and processing, solves execute-in-place in construction process The quality uncontrollability brought;
7th, this utility model is substantially realized insulation and is built the same life-span.
In sum, this utility model increases heat-insulating property durability, reduces construction cost, reduction of erection time, saves insulation The secondary construction of layer, it is possible to increase construction wall heat-insulating property, improves build guality, meets National Fire design specification, can Reach fire prevention A level standard.
The above is only to preferred embodiment of the present utility model, not this utility model is made any formal Restriction, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations with Modify, belong in the range of technical solutions of the utility model.
