Abstract

A cast-in-place sandwich self-heat-preservation composite wall sequentially comprises an outer detachment-free formwork, a composite heat-preservation layer and an inner detachment-free formwork from outside to inside. The composite heat-preservation layer is composed of rigid polyurethane foam and foam concrete, and the rigid polyurethane foam and the foam concrete are cast in place alternately; the outer detachment-free formwork and the inner detachment-free formwork are calcium silicate plates or cement pressure plates. The outer detachment-free formwork and the inner detachment-free formwork are fixed to the outer vertical face and the inner vertical face of a building framework structure respectively through fixing parts. The outer detachment-free formwork and the inner detachment-free formwork are tied and fixed through plastic tie parts. The cast-in-place sandwich self-heat-preservation composite wall has the advantages of being simple in structure, efficient in heat-preservation performance, fireproof and stable in quality, can effectively prevent the common quality problem that the surface of the wall cracks or bulges and can be widely used for the fields of building energy conservation and heat preservation.

Description

A kind of cast-in-place sandwich self-heat conserving combined wall
Technical field
The utility model relates to a kind of building cast-in-situ self heat insulation wall.
Background technology
External wall outer insulation, exterior wall internal insulation and outer wall self heat-preserving are three kinds of structural forms in current wall thermal insulation technology.Wherein external wall outer insulation exists heat insulation system limited service life, easily breaking out of fire, the various potential safety hazards such as insulating layer of external wall cracking, a drum.The defect such as external wall outer insulation also exists that working procedure is loaded down with trivial details in addition, the wasting of resources, heat-insulating property are poor.There is body of wall cold bridge place dewfall, the common quality defect such as mouldy in exterior wall internal insulation.And outer wall self heat-preserving system is because employing has the materials for wall of heat insulation function, make heat-insulation system can with the same life-span of building, eliminating disaster hidden-trouble simultaneously, reduce building costs and save the duration, is an advanced technology of current China building energy saving field develop actively.But the self-thermal insulation material using is at present generally building-block, heat-insulating property is poor, can not meet the requirement of building energy-saving standard, and after building by laying bricks or stones, has the common quality defects such as finish coat cracking, infiltration.Just, owing to there is above-mentioned shortcoming, limit the engineering application of this series products.
Utility model content
The utility model provides a kind of cast-in-place sandwich self-heat conserving combined wall, solve existing self-insulation wall material heat-insulating property poor, easily occurs the technical problem of the common quality defects such as finish coat cracking, infiltration after building by laying bricks or stones.
The utility model solves the technical scheme that its technical problem adopts:
This cast-in-place sandwich self-heat conserving combined wall, forms by exempting to tear exterior sheathing, composite heat-insulating layer open and exempt to tear open inner formword from outside to inside successively, and described composite heat-insulating layer forms by replacing cast-in-place hard polyurethane foam and foam concrete.
Describedly exempt to tear open exterior sheathing and to exempt to tear open inner formword be calcium silicate board or cement pressure plate.
Describedly exempt to tear open exterior sheathing and exempt to tear open inner formword and fixed by outer facade and the interior facade of fixture and building frame construction respectively.
Describedly exempt to tear open exterior sheathing and exempt to tear open between inner formword and fixed by plastics tension member drawknot.
The beneficial effects of the utility model are as follows:
1, adopt larger-size calcium silicate board or cement pressure plate to tear exterior sheathing and inner formword open as exempting from, piece is reduced greatly, eliminated the common quality defects such as traditional heat insulation building block float coat cracking, infiltration.
2, tear exterior sheathing open by exempting from and exempt to tear open inner formword and fixed with the frame construction of building respectively, and exempting to tear open and between inside and outside template, carry out drawknot by plastics tension member and fix, having increased the mechanical stability of combined wall.
3, adopt composite heat-insulating layer, and alternately cast-in-place by cast-in-place hard polyurethane foam and cast-in-place foamed concrete, the foam concrete that makes inorganic type has carried out fire prevention to organic type hard polyurethane foam to be cut apart, can utilize heat-insulating property that hard polyurethane foam is high and the fireproof performance of foam concrete simultaneously, improve insulation and the fireproof performance of combined wall, finally meet energy-conservation and fire protection design requirement.
That cast-in-place sandwich self-heat conserving combined wall of the present utility model has is simple in structure, high-efficiency insulated, fire prevention, stay-in-grade advantage, can effectively avoid the common quality defects such as surface of wall cracking, hollowing, can be widely used in building energy conservation heat insulation field.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1-exempts to tear open inner formword, 2-building frame construction, 3-and exempts to tear open exterior sheathing, 4-fixture, 5-plastics tension member, 6-hard polyurethane foam, 7-foam concrete.
Detailed description of the invention
Embodiment is shown in Figure 1, and this cast-in-place sandwich self-heat conserving combined wall forms by exempting to tear exterior sheathing 3, composite heat-insulating layer open and exempt to tear open inner formword 1 from outside to inside successively.Composite heat-insulating layer is by replacing cast-in-place hard polyurethane foam 6 and foam concrete 7 forms.Exempt to tear open exterior sheathing 3 and exempt to tear open inner formword 1 for calcium silicate board or cement pressure plate.Exempt to tear open exterior sheathing 3 and exempt to tear open inner formword 1 and fixed by fixture 4 and outer facade and the interior facade of building frame construction 2 respectively.Exempt to tear open exterior sheathing 3 and exempt to tear open between inner formword 1 and fixed by plastics tension member 5 drawknots.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can, in essence of the present utility model and protection domain, make various amendments or be equal to replacement the utility model, this amendment or be equal to replacement and also should be considered as dropping in protection domain of the present utility model.
