Description

A kind of aerated concrete panel and preparation method thereof
Technical field
The present invention relates to air entrained concrete field.
Background technology
2016 the beginning of the year State Council print and distribute《State Council of the Central Committee of the Communist Party of China is with regard to further strengthening urban planning and development control work The some suggestions made》In clearly propose, China will greatly develop assembled architecture, to lift construction quality, the reduction of erection time, benefit Common people.The 2016 Nian9Yue30 Information Office of the State Council put into effect《Instruction with regard to greatly developing assembled architecture》Suggestion is explicitly pointed out Assembled architecture is set to account for more than the 30% of newly-increased building with the time of 10 years, assembled architecture main thought is tied using shear wall Structure, replaces bricklay with steel concrete wall as far as possible, and internal partition wall is assembled using Aerated Concrete plate, and using aluminum alloy pattern plate template assembly is carried out, Effectively lift wall quality and reduce waste of material.
Although ordinary air-entrained concrete plate single-point hanging force has been lifted compared with ordinary air-entrained concrete building block(Single-point hanging force ≥800N)But can not still meet the hanging requirement of site operation and later stage finishing.In order that aerated concrete panel is preferably full Sufficient customer demand exploitation hanging force strengthens aerated concrete panel(Single-point hanging force >=1200N)To meet wallboard installation, and later stage Anti-theft door and window in fitment process, water heater, lampblack absorber, built-in wardrobe, television set, air-conditioning and other ornaments that need to hang installation hang Hang and require.
The content of the invention
The technical problem to be solved is:How a kind of single-point hanging force >=1200N aerated concrete panels are provided.
The technical solution adopted in the present invention is:A kind of aerated concrete panel, the aerated concrete panel is embedded on wall For hanging weight, the air entrained concrete intralamellar part is inlaid with transverse steel and vertical reinforcement, and first vertical reinforcement is apart from left side Termination 10-15mm, last root vertical reinforcement is apart from right side termination 10-15mm, first vertical reinforcement and last root vertical steel Many vertical reinforcements are filled between muscle, the minimum spacing between all adjacent vertical reinforcements is less than 600mm, first transverse steel Apart from top termination 15-25mm, last root transverse steel apart from bottom termination 15-25mm, first transverse steel and last Many transverse steels are filled between root transverse steel, the minimum spacing between all adjacent transverse reinforcing bars is less than 150mm, owns Transverse steel and vertical reinforcement all adopt the cold-drawn bar of diameter 5-6mm, according to quality meter powder in the air entrained concrete board raw material It is coal ash 53-89 parts, sand 30-90 parts, quick lime 10-26 parts, desulfurated plaster 0.5-1.7 parts, aluminium powder 0.05-0.15 parts, additional Agent 0.5-2 parts, cement 5-14 parts.
As a kind of preferred embodiment:Flyash is less than 30% according to 0.045mm screen over-sizes fineness;Clay content is less than in sand 5%, fineness is less than 20% according to 0.045mm screen over-sizes;In quick lime the content of free calcium oxide according to mass percent 65% with On, digestion condition >=70 DEG C, 12 ~ 16min of oxidation rate, ball milling fineness is 10-13% according to 0.088mm screen over-sizes;In aluminium powder According to mass percent active aluminium content >=90%;Additive is by polycarboxylic acids, pine nut ammonia soap, triethanolamine, water, by 2:1:1:6 Stir after mass ratio mixing.
As a kind of preferred embodiment:Weld together where transverse steel and vertical reinforcement are interlocked.
One kind makes aerated concrete panel method, according to quality meter by flyash 53-89 parts, sand 30-90 parts, quick lime After 10-26 parts, desulfurated plaster 0.5-1.7 parts, aluminium powder 0.05-0.15 parts, additive 0.5-2 parts, cement 5-14 parts are well mixed, The amount of half is poured into mould is first then placed in transverse steel and vertical reinforcement, finally again remaining half amount poured into mould It is compacted in tool, conserves in the saturated vapor of 200 degrees Celsius of 1-2.5 atmospheric pressure and be as cold as room temperature naturally after 4-6 hours.
The invention has the beneficial effects as follows:The enhancing aerated concrete panel single-point hanging force that the present invention is provided is more than 1500N, energy Enough hanging demands for meeting various weights at present.
Specific embodiment
Embodiment 1
The position for installing TV is needed to inlay aerated concrete panel in house interior, the aerated concrete panel is embedded on wall and uses In hanging large-scale wall hung television, the air entrained concrete intralamellar part is inlaid with transverse steel and vertical reinforcement, first vertical reinforcement away from From left side termination 15mm, last root vertical reinforcement is apart from right side termination 15mm, first vertical reinforcement and last root vertical steel 1 vertical reinforcement is filled between muscle, the spacing between all adjacent vertical reinforcements is 500mm, and first transverse steel distance is pushed up Portion termination 20mm, last root transverse steel apart from bottom termination 20mm, first transverse steel and last root transverse steel it Between be filled with 3 transverse steels, the spacing between all adjacent transverse reinforcing bars be 150mm, all transverse steels and vertical reinforcement All using the cold-drawn bar of diameter 5mm, according to quality meter flyash 53-89 parts, sand 30-90 in the air entrained concrete board raw material Part, quick lime 10-26 parts, desulfurated plaster 0.5-1.7 parts, aluminium powder 0.05-0.15 parts, additive 0.5-2 parts, cement 5-14 parts.
