Description
Technical field
Separate dies cavity and make the method for heterogeneous body steam-pressing aero-concrete wall body construction, belong to the energy-conserving construction wall technical field.Be specifically related to a kind of manufacture method that adopts the technical measures production steam-pressing aero-concrete heterogeneous body wall body construction of separating dies cavity.
Background technology
In the energy saving building field, the steam-pressing aero-concrete member occupies great share in the body of wall of building enclosure.At present, these members all are " homogeneous materials ", and each is to the homogeneity same sex.
Each position of body of wall, the suffered load of all directions do not wait, the function of use difference, and isotropic steam-pressing aero-concrete member can not satisfy comprehensive demand of body of wall, and building wall is usually taked many additional measures, and is as pre-buried, cast-in-place, the cutting of part, very numerous and diverse.One of problem that to simplify these additional measures are construction technology progress.
Invent a kind of process, make wall body construction with steam-pressing aero-concrete, the position of the variant functional requirement of member, employing can be satisfied the steam-pressing aero-concrete proportioning of functional requirement, corresponding functional requirement can both be satisfied in each position of realization member, is the useful item of an intention distinctness.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of method that dies cavity is made steam-pressing aero-concrete heterogeneous body wall body construction of separating is provided, this method is utilized existing steam-cured air-entrained concrete building block production line, idiosome is bred dies cavity be divided into two or more different zone, and the different slip of difference injection efficiency, form the heterogeneous body wall body construction by precuring, cutting, maintenance.
The technical solution adopted for the present invention to solve the technical problems is: this separation dies cavity is made the method for steam-pressing aero-concrete heterogeneous body wall body construction, it is characterized in that: may further comprise the steps:
1.1, according to the functional requirement at each position of body of wall and wall body construction build arrangement mode, construction technology by laying bricks or stones, set the shape and size of heterogeneous body wall body construction; And determine the requirement such as intensity, density of the material at each position of steam-pressing aero-concrete heterogeneous body wall body construction according to the corresponding standard of load character, size and engineering construction;
1.2, according to requirements such as the intensity at each position of heterogeneous body wall body construction of determining in the step 1.1, density, determine the density of the steam-cured air entrained concrete that adopt at each position of heterogeneous body wall body construction and the proportioning that slip is made;
1.3, make idiosome cutting planning according to idiosome size, idiosome mould and the cutting power of member production line, and cut planning according to idiosome and determine position and the attitude of heterogeneous body wall body construction in the idiosome mould, determine the separation scheme of dies cavity and make the separation assembly according to position and attitude then;
1.4, utilize positioning strip, will separate assembly and lay into dies cavity, form subregion;
When the slip of by stages takes place to surpass the seepage of permissible value, add elastic spacer:
1.5, according to the slip proportioning of determining in the step 1.2, carry out the configuration of slip;
1.6, the slip carrier pipe of used slip by separately is injected into corresponding subregion with dies cavity, carry out embryo development;
1.7, treat that slip grows to semisolid or initially solid-state, remove positioning strip, vertically propose to separate assembly, continue maintenance to idiosome and form;
1.8, the demoulding, be cut into the semi-finished product of heterogeneous body wall body construction;
1.9, according to designing requirement and real needs, the annex of heterogeneous body wall body construction is inserted into assigned position on the member;
1.10, the semi-finished product maintenance is become the heterogeneous body wall body construction.
Slip described in the step 1.5 is that two or more are similar but slip that performance is different.
Described separation assembly is at the figure that is projected as the straightway besieged city of mould bottom surface.
Described separation assembly on the mould bottom surface projection or be waveform, convex-concave broken line shape; Also can under the condition that does not influence proposition, do the rigidity reinforcement with stiffening plate; Separate assembly and also can be constituted by many discrete circular cross-sections, the straight tube of square-section, can be independent between each straight tube, also can UNICOM, but each straight tube need inject quantitative slip respectively when independent under the situation of reliable location.
Compared with prior art, the beneficial effect that has of the present invention is:
The method of utilizing separation dies cavity of the present invention to make steam-pressing aero-concrete heterogeneous body wall body construction can be utilized existing steam-cured air-entrained concrete building block production line, idiosome is bred dies cavity be divided into two or more different zone, and the different slip of difference injection efficiency, form the heterogeneous body wall body construction by precuring, cutting, maintenance.Utilize this method can make body of wall heterogeneous body member, as the high thermal resistance of internal layer low-density, strong noise damping capacity, the high resistance to compression bending resistance of outer high density, high rigidity, can follow closely and to hang; The high heat group of the whole low-density of member, local high density can arrange anchor point for another example; Also possesses linkage function etc. as parts such as the high heat of the whole low-density of member group, end faces.
Method based on the manufacturing body of wall heterogeneous body member of dies cavity sequestered partition can produce the wall body construction that kind is numerous, function is different, and these members are by batch production production, and cost is low, efficient is high.Can gradually reduce the additional measure of wall construction, the partial insulation cast-in-place as the part, that heat bridge cuts off etc.; Simplify work progress, save man-hour, material and reduction consumption, have huge economic benefit.Simultaneously, progressively improve " assembled " construction proportion of building wall, have distinct technological progress meaning and social benefit.
