Description
Technical field
The present invention relates to the cutting method of air-entrained concrete building block.
Background technology
Air-entrained concrete building block is because of the high building industry that is widely used in of its intensity in light weight.The production process of air-entrained concrete building block generally comprises following step: at first, the concrete mixture slurry is poured in the injection molding, slip forms the soft paste body after getting angry through resting and hardening, then with the demoulding of soft paste body; Secondly, it is rip cutting and crosscut that the soft paste body is cut, thereby forms polylith rectangle briquet; At last, with the building block of the steam-cured one-tenth hardware of briquet.For the ease of the demoulding, oiling on the inwall of injection molding will watered before the cast, the soft paste body is deviate from its upper surface out-of-flatness of back, be attached with one deck greasy dirt on other surface, if upper surface is not cut the flat building block that just can not get regular shape, if other top layer of adhering to greasy dirt is not cut away, will influence building block in use with the combining of binding agent, therefore to excise six lip-deep top layers of soft paste body, be commonly called as " six peelings ".
At present, the cutting method of soft paste body is had two kinds, a kind of is twice upset of base substrate patterning method, and another kind is a base substrate once inside out patterning method.
The specific operation process of twice of base substrate upset patterning method is as follows: with the corresponding mould frame of this cutting method be drop-bottom mould frame, the end face of drop-bottom mould frame and bottom surface be opening all, the cast moulding box of with the plane base plate bottom surface sealing of mould frame being formed an end face opening during group mould, behind concrete mixture slurry injection moulding box, make slip become the soft paste body through resting, then the mould frame being separated with the plane base plate deviates from the soft paste body in the mould frame, soft paste body after the demoulding lies low on the plane base plate, again the upset of soft paste body is erected for 90 °, the soft paste body that erects forms many long base bars that pile up together behind the slitter slitting striping, the soft paste body be cut into many long base bars the time its on, down, a left side, the top layer on right four surfaces is cut, on, a left side, the top layer on right three surfaces breaks away from the soft paste body, the top layer of lower surface is still stayed on the plane base plate, after rip cutting is finished the soft paste that is cut into many long base bars is carried out crosscut and become block operations, top layer when promptly will the crosscut of long base bar becoming polylith rectangle briquet with transverse cutting unit on its both ends of the surface is also cut, after crosscut is finished, the soft paste body upset that will be cut into building block again lies low on steam-cured soleplate it for 90 °, this moment, the above-mentioned top layer of still staying the lower surface on the plane base plate just became a side of soft paste body, divest this top layer, steam-cured soleplate forms one steam-cured group together with the soft paste body that is cut into briquet.After producing steam-cured group of defined amount, steam-cured group of many groups putting into and carry out steam-curedly in the steam-cured still in layer from bottom to top, briquet has just become building block after steam-cured the finishing.
There is following shortcoming in twice upset of base substrate patterning method: the one, and the soft paste body makes internal injuries such as the inner formation of soft paste body crackle easily after twice upset, and the yield rate of building block is low; The 2nd, steam-cured soleplate must be the level of state in steam-cured still, on steam-cured group below last steam-cured group can not be pressed in again of position, need steam-cured group in layer be propped up with a large amount of struts, wastes time and energy, and causes steaming efficiency very low.Certainly the soft paste body that is cut into briquet being overturn again once makes it to erect, and just do not need strut when steam-cured, but the number of times that overturns is many more, and the internal injury that soft paste body and briquet are caused is just bigger, and the yield rate of building block can be lower, and the quality of building block more can not guarantee.
The specific operation process of base substrate once inside out patterning method is as follows: with the corresponding mould frame of this cutting method be laterally opened mould frame, the end face of laterally opened mould frame and a lateral opening, the cast moulding box of with the plane side plate side-closed of mould frame being formed an end face opening during group mould, behind concrete mixture slurry injection moulding box, make the slip sclerosis of getting angry become the soft paste body through resting, to pour into a mould 90 ° of moulding box upsets then, make below the plane base plate is positioned at, the mould frame separated with the plane base plate soft paste body is deviate from the mould frame, soft paste body after the demoulding stands on the plane base plate, though the soft paste body is also through once inside out, but, can not cause the inside internal injury of soft paste body in the cast moulding box because the soft paste body overturns with the cast moulding box.The soft paste body that stands on the plane base plate also will become piece with crosscut through slitting striping, and slitting striping becomes identical in the process of piece and twice upset of the above-mentioned base substrate patterning method with crosscut.Different is, the soft paste body that is cut into briquet still stands on the plane base plate, the top layer of the lower surface that is cut off is also stayed on the plane base plate, no longer overturn, the plane base plate is formed one group steam-cured group together with top layer on it and the soft paste body that is cut into briquet, after producing steam-cured group of defined amount, putting into of being listed as of steam-cured group one of many group to be carried out steam-cured in the steam-cured still, briquet has just become building block after steam-cured the finishing.
Though base substrate once inside out patterning method can not cause inner internal injury to the soft paste body, do not need strut when steam-cured yet, can bring the two high benefits of building block yield rate and steaming efficiency, also there is very big shortcoming.Since also participated in by the top layer of the lower surface that cut off steam-cured, steam-cured after this top layer become hard waste residue, not only strengthened steam consumption quantity, wasted the energy, and resource but also contaminated environment had not only been wasted in the generation of hard waste residue.
