Abstract
A kind of composite slab made up of ash and cement with binding wires, form by outer coversheet 1, internal surface layer 2, insulation layer 3, reinforced frame 5, waterproofing course 4 and vapour barrier 6, inside and outside surface layer is to be Main Ingredients and Appearance with flyash, admix cement and become base material, add mineral fibers again and formed by plant fibre forms, this wallboard is applicable to individual layer load-bearing side fascia, the light plate building system of multistory frame exterior wall cladding, inner wall panel, load-bearing insulation layer panel, it is used for building and adds layer except that being applicable to industry and new civil engineering, temporary building, assembled house, architectural featurette and scenic spot building are even more ideal.This combined wall board building physics performance is good, and cost is low, and industrial residue flyash is turned waste into wealth.
Description
The present invention relates to a kind of construction material.
At present a large amount of buildings of China still along continuous use brick, watt, traditional materials such as sand, stone.Not only the construction period long, clumsy from adopting, produce, transportation, consumed a large amount of labours, the transport power and the energy to use.Serious is to destroy, consume the human land resources that is difficult to create.
It is extremely urgent developing building material for this reason.China's building material development now is very fast, is applied to the architectural gas concrete class that mainly contains, light weight aggregate concrete class and compound external wall panel class etc.The compound external wall panel class has glass fiber to strengthen side fascia, it is to be that raw material is made the two sides and respectively is the GRC shell of 10mm with alkali resistant glass fiber, cement, sand, the side fascia that is composited with 100～150mm thick insulation layer is filled out in the centre, the thermal technology that can satisfy northern area requires to be used for the light panel frame structure, but cost is higher.In recent years national " six or five " brainstorm project " thin wall concrete rock wool compound external wall panel ", it is the three-layer composite board by the inside and outside surface layer therebetween of concrete rock cotton board.The structure skin of its plate is the thick concrete of 30mm, and internal layer is the thick concrete structure layer of 50mm, the thick rock cotton board insulation layer of therebetween one deck 80mm, and two ectonexines φ 8 reinforcing bar junctional complexs, thermal property is better, the every m of 160mm thickness of slab
2The heavy 256kg/m of plate
2, be used for multilayer, the light plate building system of high-rise frame non-bearing exterior wall cladding.
Task of the present invention is to be that primary raw material is made a kind of building physics mechanical performance index that both satisfied with industrial residue flyash, again multiple function of tool and economic composite slab made up of ash and cement with binding wires.
Technical solution of the present invention is to realize like this.Composite plate of the present invention is made up of outer coversheet, insulation layer, internal surface layer, and outer coversheet and internal surface layer are the pulverized fuel ash cement fibre structure, is to be Main Ingredients and Appearance with flyash, and admixing cement becomes that base material adds rock wool again and formed by plant fibre forms.The reinforced frame made from reinforcing bar connects two surface layers and reinforces then, and the external surface of outer coversheet is spread waterproofing materials, between internal surface layer and the insulation layer vapour barrier is set.The percentage by weight of various compositions is flyash 55-66, cement 28-36, paper pulp 2-3, rock wool 4-6, adds the water of above-mentioned composition gross weight 35～45% again in outer coversheet and the internal surface layer structure, stirs, and dewaters to 18-20%.
The composite plate mechanics index depends primarily on surface layer, and the main material of manufacturing surface layer is a flyash.Flyash itself does not have intensity, but the material that contains in its composition truly has certain activity.Behind it and cement mix, generate a series of hydrated product, produce tangible intensity, and alkali is had the effect of inhibition and chemical stability.Have physical characteristics such as unit weight is light, fineness is little, coefficient of thermal conductivity is low simultaneously concurrently.In addition, dope mineral fibers and quantitative string to improve the physical and mechanical property of matrix, it plays a part to transmit and bear external force, to change the fragility of plane materiel, increase toughness and impact resistance, reduce thermal conductivity, can make plane materiel that workability is arranged and the adhesive power of plastering.
Composite plate of the present invention has the following advantages:
1, product employing industrial residue flyash of the present invention is main raw material(s), every production 1m
3The surface layer plate utilizes 760kg flyash, so changing waste into valuable when can reduce the composite plate cost brings benign cycle to society.
2, product deadweight of the present invention is little, every m when thickness 20cm
2Plate heavily is 172kg, and is as follows with the more specific data of other type wallboard with suitable heat-insulation and heat-preservation ability:
| The wallboard classification | Thickness (mm) | Every m 2Weight kg/m 2 | With this product weight ratio |
| Wallboard of the present invention | 200 | 172 | 1 |
| Thin wall concrete rock wool combined wall board | 160 | 256 | 1.5 |
| Gas concrete piece body of wall | 250 | 203 | 1.2 |
| The haydite concrete plate | 300 | 553 | 3.2 |
| The loam brick body of wall | 490 | 984 | 5.7 |
3, product of the present invention has good thermal property.Its thermal resistance value R=0.864m when compound thickness of slab 130mm
2.K/W; Be equivalent to the thick loam brick of 490mm, the thermal resistance value of 160mm thick and thin wall concrete rock wool side fascia.When get thick product of 200mm be used for architectural, its thermal resistance value R=1.578m
2.K/W, has obvious energy-saving effect.
4, cost of goods manufactured of the present invention is low.These product steel, cement is by negotiating a price, and all the other materials calculate by the current market price, produce the every m of thick 200mm composite plate
2Cost is 38.80 yuan, builds thick 490mm common brick wall by laying bricks or stones, and interior wall plastering 2cm is thick, every m
2Cost is 53.90 yuan, and thin wall concrete rock wool-steel plywood workshop cost is 40 yuan/m
2(price in 1985).
5, product of the present invention has workability and the adhesive power of plastering.
Accompanying drawing is the structural representation of product of the present invention.
Further specify technical scheme of the present invention in conjunction with the accompanying drawings:
