Description
Technical field
The present invention relates to a kind of forming method and device of hollow aerated bricks of building non-bearing wall body for highrise building by laying bricks or stones, belong to building brick or building block technique field.
Background technology
Aerated bricks is the abbreviation of " Autoclaved aerated concrete blocks ", it is a kind of light heat insulation material that contains a large amount of sealed porositys, take siliceous material (sand, flyash and containing silicon tailings etc.) and calcareous material (lime, cement) as primary raw material, admixture foaming agent (aluminium powder), through adding water, stir, by chemical reaction, form hole, the porous silicate goods of making by activitiess such as moulding by casting, precuring cutting, steam press maintenances.There is following characteristics: 1. lightweight: weight is 500-700kg/m
3, being only equivalent to loam brick 1/4-1/5,1/5 of ordinary concrete, is the lighter one in concrete; 2. thermal and insulating performance is good, and coefficient of thermal conductivity is low: the coefficient of thermal conductivity of gas concrete is 1/6 of ordinary concrete, and heat-proof quality is better than the loam brick body of wall that 240mm is thick greatly; 3. shock resistance is strong; 4. good processability: can saw, dig, nail, milling, brill, to construction bring great convenience with flexibly; 5. there is certain heat-resisting quantity; Compressive strength when its compressive strength approaches normal temperature when 600 degree left and right; 6. sound insulation value is good; 7. anti-pressure ability is strong.Concrete preparation process is, various components are pulverized and mixed and make slip according to proportioning, and slip should reach the technological requirement of approximately 45 ℃ before cast, as inadequate in temperature, can, in the logical Steam Heating of slip measuring tank, within 0.5～1 minute before cast, add aluminium powder suspension.Slip casting, in framed, push and just supports the chamber initial set of getting angry, and room temperature is 48～68 ℃, and just supporting the time is 1.5-2 hour, quiet oxygen foamed solidification.After just supporting, framed and base substrate are together hung on the cutting bed of putting in advance still base plate well, slough framed, cutting machine carries out crosscut, rip cutting, milling crust to base substrate, framed hanging got back to labor cleaning and oil removing on mould carriage, then hang mould car upper group mould and pour into a mould next time, the base substrate after cutting hangs on still car together with still base plate, is transported to still kettle and under the vapor action of certain pressure and temperature, carries out maintenance, pressure is generally 1Mpa-1.3Mpa, and temperature is generally 180-210 degree.
At present, to the improvement of aerated bricks, be mostly in the selection of raw material, < < as disclosed in CN102887725A aerated bricks and processing method > > thereof who utilizes useless building waste to produce, aerated bricks and processing method > > thereof that the disclosed < < of CN102887674A modified straw ash is produced, mono-kind of the disclosed < < of CN102992803A aerated bricks and the processing method > > thereof take slag as matrix, the disclosed < < of a CN102875186A fluorite slag aerated bricks and preparation method thereof > >, mono-kind of the disclosed < < of CN102875070A utilizes carbide slag production aerating hollow brick method > >, the disclosed < < of CN103449763A cracking resistance aerated bricks > >, the disclosed < < of CN102887725A aerated bricks and processing method > > thereof who utilizes useless building waste to produce, the disclosed < < of CN103449770A frost-resistant concrete aerated bricks > >.These methods are all by selecting different raw material and proportioning, improve the performance of aerated bricks.
The disclosed < < of CN202787632U hollow aerated bricks > >, be shaped as cuboid, have along its length a through hole coaxially running through or a side, have groove along its length, its objective is when construction, placing of concrete after secondary structure is contained in through hole, groove in advance, the brick face of hollow aerated bricks, as the basal plane of secondary structure, is convenient to plastering construction.Although this brick is also referred to as hollow aerated bricks, but its hollow effect is in order to facilitate secondary structure, and being along the perforate of brick body length direction, is not the hollow brick (GB 13545-2003 < < Fired hollow bricks and blocks > >) stipulating in national standard.
Aerated bricks is made to hollow further weight reduction, also do not occur in the market hollow aerated bricks.
Summary of the invention
The present invention is directed to the deficiency that existing aerated bricks (Autoclaved aerated concrete blocks) technology exists, the hollow aerated bricks at the bottom of a kind of unit weight is provided, a kind of forming method and shaped device of this hollow aerated bricks of simple to operate, easy moulding is provided simultaneously.
Hollow aerated bricks of the present invention is to be provided with hole in the brick body of aerated bricks.The shape of hole can have any shape, and can be one, can be also arrange arbitrarily spaced apart from each other multiple.
The forming method of above-mentioned hollow aerated bricks, before slip casting is in framed, first in framed, insert the forming blocks with hole cross sectional shape and position consistency, then at framed middle cast slip, slip is carried out just supporting, make the slip initial set of getting angry, after initial set finishes, forming blocks is extracted, finally the brick body of moulding is carried out steam-curedly, make and be with pertusate hollow aerated bricks.
Realize the shaped device of the hollow aerated bricks of said method, by the following technical solutions:
This device, comprises support, crane and elevating mechanism, and elevating mechanism is rack-mount, and crane is connected with elevating mechanism, and the bottom surface of crane is provided with forming blocks.
The present invention has generated hole in the preparation process of aerated bricks, is easy to moulding, and without process hole on solid aerated bricks, easy to operate, process is simple.
