Abstract
The invention discloses a kind of novel prefabricated building structure heat insulation decorative load-bearing walls, are related to building material field, it is intended to solve the problems, such as that prefabricated assembled exterior wall insulated structure needs inconvenience of constructing caused by being connected and fixed by adhesive or connector in the prior art.Its key points of the technical solution are that including the supporting course made of steel fiber reinforced concrete, the tow sides of supporting course be both provided with the insulating layer made of foam concrete, decorative layer be both provided on insulating layer, and be additionally provided with screed-coat between insulating layer and decorative layer.The present invention has advantage easy for construction, load-bearing capacity is strong, freeze proof cracking resistance and thermal and insulating performance are good.
Description
Technical field
The present invention relates to a kind of dry walls, more specifically, it relates to a kind of novel prefabricated building structure load bearing heat preserving dress
Adorn wall.
Background technology
Dry wall refers to being processed into the concrete plate-shaped component for building assembly in precast plant or construction site, referred to as
Wallboard or siding.Assembled large panel building is built using precast concrete wall panel, batch production, mechanized construction journey can be improved
Degree reduces situ wet operation, saves live recruitment, overcomes seasonal effect, shortens the construction period.Traditional dry wall is general
It is by reinforcing bar and concrete support, though load bearing effect is good, its heat insulation and preservation effect is not ideal enough.
In the prior art, the Chinese patent of Authorization Notice No. CN201981657U discloses outside a kind of prefabricated assembled exterior wall
Insulation construction comprising：Heat preserving and insulating material layer, prefabricated reinforced concrete protect wallboard, heat preserving and insulating material layer to be arranged pre-
On the inside of armored concrete protection wallboard processed, prefabricated reinforced concrete protection wallboard is divided into polylith junior unit structure by elevation of building structure
Part.Its expansion polyphenyl plate, extruded polystyrene board, polystyrene foam plastics or glass fibers by adding low thermal conductivity in metope
The heat-insulating heat-preserving materials such as vinylon and cotton blend, to increase the heat-insulation and heat-preservation of wall.
But this kind of thermal insulation material usually requires to fix with wallboard by connector or adhesive, increases and applies
Work workload, has much room for improvement.
Invention content
In view of the deficiencies of the prior art, the present invention intends to provide a kind of novel prefabricated building structure load-bearing guarantor
Warm decorative wall, with the advantage that easy for construction, load-bearing capacity is strong, freeze proof cracking resistance, insulation and fire resistance are good.
A kind of novel prefabricated building structure heat insulation decorative load-bearing wall, including supporting course, the tow sides of the supporting course are equal
It is provided with insulating layer, decorative layer is both provided on the insulating layer；The supporting course is made of steel fiber reinforced concrete, the heat preservation
Layer is made of foam concrete；It is additionally provided with screed-coat between the insulating layer and decorative layer.
By using above-mentioned technical proposal, have the advantages that have as follows compared to the prior art：One, steel fiber concrete layer is made
For the main supporting course of wall, intensity is high, good, the not easy to crack and more traditional reinforced concrete structure of bending resistance compressive property
Wall is at low cost, construction is also more convenient；Two, foam concrete has good heat-insulation and heat-preservation, good frost resistance, and foam is mixed
Solidifying soil insulating layer has preferable compatibility with steel fiber reinforced concrete supporting course, is less prone to similar steeps in the prior art each other
The thermal insulation materials such as foam plastics are easy the case where being removed between wall, and use is more durable；Three, screed-coat can fill up insulating layer
The pit-hole on surface, so that wall surface levelling, is conducive to the construction of decorative layer, improves the adhesive fastness between decorative layer and insulating layer,
So that decorative layer is smooth, is not easy to be bubbled；Four, decorative layer can select coating decoration, mortar powdering etc. there are many selection；
Five, for foam concrete as insulating layer, fire resistance is more preferable.The present invention is both provided with insulating layer, insulating layer on the two sides of supporting course
On be both provided with screed-coat and decorative layer so that the whole load-bearing capacity of wall is strong, freeze proof cracking resistance and heat preservation and insulation are excellent,
And also there is certain absorbing sound and lowering noise effect.
Further, the screed-coat batch is scraped by putty, the putty by cement, sand material, aqueous epoxy resins and
Hydroxypropyl methyl cellulose adds water to be formulated.
By using above-mentioned technical proposal, cement and the main material that sand material is putty ensure that putty layer energy and insulating layer
There is enough intensity after having preferable compatibility, condensation；Aqueous epoxy resins and hydroxypropyl methyl cellulose have increase levelling
The effect of layer caking property so that decorative layer is not easy to crack, is bubbled.
Further, the mass percent content of each component is in the putty, cement 30%-40%, sand material 45%-50%,
Aqueous epoxy resins 1%-1.5%, hydroxypropyl methyl cellulose 3.5%-4.5%, surplus are water.
By using above-mentioned technical proposal, the putty adhesiveness of this kind proportioning is good, batch scrape on insulating layer after be not easy because of stream
It is dynamic that levelling layer thickness is caused to differ, it is conducive to the construction of subsequent decorations layer.
Further, the steel fiber reinforced concrete includes following component, and content is calculated as by weight percent, cement 18%-
28%, silicon ash 2.5%-3.5%, flyash 2.5%-3.5%, steel fibre 3.5%-4.5%, river sand 20%-30%, rubble 30%-35%, steel
Fiber concrete additive 0.5%-1%, surplus are water.
By using above-mentioned technical proposal, using the concrete prepared by silicon ash, flyash, river sand and rubble, intensity is good,
It can guarantee that wall has enough load-bearing capacities；Steel fibre is intensity reinforcing component, can be dispersed in concrete and be formed uniformly
Reinforcing rib, promotes the resistance to compression bending strength of concrete, while having and reducing concrete cracking and minute crack is prevented to continue to expand
Effect；Steel fiber reinforced concrete additive has the aquation for slowing down concrete slump loss, promoting cement, promotes concrete
The effect of intensity.
Further, the mass percent content of each component is that polycarboxylic-acid subtracts in the steel fiber reinforced concrete additive
Aqua 25%, slump retaining agent 5%, polyvinyl alcohol 2.5%, polymethylacrylic acid 2%, calgon 0.5%, sodium sulphate 1.5%, poly- silica
Alkane 0.1%, surplus are water.
