Abstract
The present invention provides a method for making a fiber-reinforced cement flue passage whose steps comprise: cement is formed, templates 1, 2 on both sides are vertically fixed on a bottom template 3, and the slurry is cast to make a bottom plate 4 which is provided with a core die 5. Through casting the slurry, side plates 6, 7, a partition plate 8 and an upper plate 9 are made, are maintained to demoulding, and are maintained to a finished product. The present invention has the advantages of easy operation, simple operation, etc. The product made with the method has the characteristics of high strength and prevention of contrary wind back flow.
Description
The present invention relates to a kind of preparation method of building unit, particularly about a kind of preparation method of fiber-reinforced cement flue pipe.
At present, in the patent documentation of notification number CN2071226U, a kind of magnesite concrete ventilation (cigarette) road is disclosed, logical (cigarette) road of this magnesite concrete is " the magnesite concrete for preparing is injected the mould of making by designing requirement; the moulding of vibrating; form removal after the initial set, middle hole adopts core pulling method once to survive ".There is following shortcoming in this preparation method:
1, mould is required height.Described in prospectus " mould can be made with timber, steel, plastics, the surface will brush corrosion resistant coating, be coated with cured "." mould and fuse all need plastic material film ".
2, because the technological requirement of " each duct has two fuses respectively; fuse has tapering slightly, and (cigarette) two, road that ventilates is slightly larger " causes each position sectional dimension of product channels inconsistent, it is unobstructed but also pour in down a chimney phenomenon in case of producing against the wind easily like this, not only to influence air-flow.
3, because disclosed product belongs to thin-wall member, adopt the disposable moulding of vibrating, be difficult to protect the uniformity consistency of product density and intensity, and strengthened demoulding difficulty.
The purpose of this invention is to provide a kind of simple to operately, can guarantee the preparation method of the fiber-reinforced cement flue pipe that the unobstructed anti-reverse wind-fall of its product strength height, air-flow is irritated.
Technical solution of the present invention is: form cement slurry, two side templates 1,2 are vertically fixed on the soffit formwork 3, the cast slip makes base plate 4, on base plate 4, lay core 5, the cast slip gets side plate 6,7, dividing plate 8 and upper plate 9, and maintenance is to the demoulding, and maintenance is to finished product again.
Described cement slurry can be with the formation that stirs in proportion of cement inorganic material, packing material, Admixture, water, fiber.
The weight proportion of cement inorganic material, packing material, Admixture, water, fiber can be 100: 30～and 200: 0.01～5: 10～200: 0.5～5.
The present invention compared with prior art has processing ease, makes simple advantage, and according to said method the product of being produced has the intensity height, can anti-reverse wind-fall filling etc. characteristics.
Fig. 1 is the sectional schematic diagram of the embodiment of the invention.
The present invention will be further described below in conjunction with the drawings and the specific embodiments: as shown in Figure 1, with magnesium cement, flyash, air entraining agent, water, the short fiber of cutting is 100: 50: 0.07 by weight: after the mixing in 30: 5, stir and make slip, fixed mount 10 is placed on two side templates 1,2 and the soffit formwork 3, make two side templates 1,2 be vertically fixed on pours slurry on the soffit formwork 3, make base plate 4, on base plate 4, lay core 5, and then cast slip, make side plate 6,7 dividing plates 8 and upper plate 9, maintenance to the demoulding, after the demoulding again maintenance to finished product.
