Description

Precast foam concrete arrangement of reinforcement wallboard and its production method
Technical field
The present invention relates to a kind of precast foam concrete arrangement of reinforcement wallboard and its production methods.
Background technology
Industry is required for a large amount of materials for wall with civil buildings.Materials for wall typically constitutes from building in building construction Half.China's construction material is still a large amount of at present
Using solid clay brick, the good soil in a large amount of good farmland is damaged, has consumed a large amount of energy.
For clay brick from great, heat preservation and insulation is poor, it is impossible to adapt to building energy conservation and the needs of building industrialization simultaneously.
Since last century the nineties, walling innovation is made that important tribute for building materials industry and town and country construction sustainable development It offers.But China urban and rural areas disparate development, space development is extensive low, and resource constraint is becoming tight, and deterioration of the ecological environment trend is still Do not obtain fundamental reversal, containment ruin field bake bricks, saving and protection resource, development essential safety, energy conservation and environmental protection, high-strength light it is novel The development problem and building materials industry that the building materials industry that walling also becomes urgently cracks adhere to innovation driving enhancing development inner system dynamics Objective requirement.
With the development of national economy, the needs of industrial or agricultural and transportation construction, the increase of population and people's lives The soil and materials for wall that horizontal raising, industry and civil buildings need will be constantly increasing, and the soil money that China is limited Source is then fewer and fewer, and the industrial residue of discharge is then more and more, shows that the annual materials for wall in China produces at present according to relevant information Energy consumption and the nearly 100,015,000 tons of standard coals of building heating energy consumption, account for about the 15% of annual energy consumption total amount, and energy consumption is passed Gaining rate is more than the growth rate of China's energy.The novel wall material type socially occurred in recent years is more and more, wherein should With more, there are gypsum or cement light partition wall board, color steel, air-entrained concrete building block, steel wire net rack cystosepiment, small-sized coagulation Native building-block, plasterboard, gypsum block, figuline building blocks, sintered perforated brick, shale brick, solid concrete brick, the big plates of PC, water Flat hole concrete panel, activated carbon wall etc., investment of often founding the factory is big, production cost is high, product price is high.
Invention content
The purpose of the present invention is to provide it is a kind of it is at low cost, from heavy and light, intensity is high, have preferable antidetonation, fire prevention, every Heat, the precast foam concrete arrangement of reinforcement wallboard of heat-insulating property and its production method.
The present invention technical solution be：
A kind of precast foam concrete arrangement of reinforcement wallboard, it is characterized in that：One is fixed on by the steel wire, reinforcing bar, built-in fitting of forming It rises, forms general frame, with foam concrete one-piece casting into wallboard；The foam concrete by foaming agent water solution, cement, Aggregate, water through mixing, moulding by casting, conserve；The aggregate of foam concrete is coal ash and/or the waste residue of its product.
In the foam concrete, mass ratio：Cement:Water:Foaming agent water solution=2:1:0.005.
The foaming agent water solution presses 1:20 are diluted with water, 30 times of calculating of coefficient of foaming.
Foam concrete dry density≤the 1000kg/m3, thermal conductivity factor≤0.27W/ (m.K), mean compressive strength >=5MPa, minimum compression strength >=4.25MPa, water absorption rate≤15%.
A kind of production method of the precast foam concrete arrangement of reinforcement wallboard, it is characterized in that：Sizing punching block is made first, Brushing releasing agent again, then reinforcing bar is bound, built-in fitting and suspension centre are fixed, subsequent built-in electric wire pipe fitting, then pour foam concrete, Then steam press maintenance, last form removal, label, scene storage.
It is an advantage of the invention that:Space utilization factor is big, and building block brick wall thicker than 20cm improves effective usable floor area 6-8%, Economic benefit is correspondingly improved.Wet construction is small, and speed of application is fast, and 5 times of effect or more is improved than building block brick wall.Conduct oneself with dignity small, Unit area plate weight (16cm is thick) is less than a quarter of clay brick wall.Shock resistance is good.Heat preservation and insulation is good.16cm thickness The plane thermal resistance of wallboard of the present invention is 0.59m2.K/W, and 24cm thickness clay bricks wall heat resistance be 0.296m2.K/W.Fire protecting performance It is good, belong to non-combustible.
Separately since wall of the present invention is from heavy and light, respective block trestle beam section is reduced, amount of reinforcement phase
It should reduce, foundation engineering amount is accordingly reduced, and freight volume is reduced, and comprehensive cost can reduce 5 one 8%.In addition, also save good farmland Good soil (10,000 m210 mu or so of building conservation), 10,000 m2Building is also using flyash 1000m2, it is another to save 73 tons of marks of energy consumption Quasi- coal.With good social benefit, economic benefit and environmental benefit, meet the direction of current materials for wall development --- it is large-scale Change, lighting, energy-saving, sharp uselessization, a Composite, have a vast market prospect.
The lightweight concrete wall panel of the present invention（16cm is thick）Basic mechanical design feature:
Serial number Project It is required that Remarks
1 Surface density ≤160 Under drying regime
2 Shock resistance, it is secondary ≥5 30kg sandbags, center of gravity put impact monoblock wall in L/2
3 Compression strength, MPa ≥5
4 Coefficient of softing ≥0.8
5 Drying shrinkage value, ≤0.6
6 Hanging force, N ≥1000
7 Water absorption rate, % ≤15
8 Fire endurance, h ≥1
9 Heat transfer, W/ (m.k) ≤0.27
10 Air sound transmission loss, dB ≥45
The production method of the present invention is relatively simple, and construction is easy to make.
With reference to embodiment, the invention will be further described.
