Abstract
The invention relates to a one-time reinforcing bar-arranging and rapid forming method of a magnesite composite agricultural shed support, a forming mold consists of an inner edge mold plate, an outer edge mold plate and tightening clamps, wherein the inner edge mold plate and the outer edge mold plate respectively have end plates, and the inner edge mold plate and the outer edge mold plate are aligned and positioned through the end plates and further fixed by the 3-7 tightening clamps; 4-8 bamboo reinforcing bars are arranged in the mold, interpenetrated and assembled by a stainless steel wire mesh and then mounted in the mold once; and magnesite composite slurry which is well stirred is poured into the mold once, compacted by vibration on a vibration table and then stricken off, curing with the mold is carried out in a curing chamber with the temperature of 40 DEG C and the relative humidity of 60%-70% for 8h, then demolding is carried out, and the curing is continuously carried at room temperature till 7d after the demolding, thereby being put into use. The one-time reinforcing bar-arranging and rapid forming method has high forming efficiency, convenient assembly and disassembly of the mold, smooth surface of a formed product and dense structure.
Description
Technical field
The invention belongs to magnesite composite and make the field, relate to a kind of one-time reinforcing bar-arranging and rapid forming method for preparing magnesite composite agricultural shed support.
Background technology
Magnesite composite agricultural shed support is to utilize magnesium oxychloride cementing material (light calcined magnesia and the preparation of magnesium chloride hexahydrate solution) interpolation light filler or blowing agent that quality is lightened, and admixture modifier etc. is through stirring into the plasticity slurry, moulding by casting in mould, be to improve the bearing capacity of material, need be furnished with glass fiber reticular cloth in the mould or bamboo reinforcement plays booster action.Preparation method at present commonly used adopts the manual manufacture wooden model, and the lined with PVC plastic plate is made mould, the magnesite slip that stirs will with glass fiber reticular cloth or bamboo reinforcement laminated pouring, generally want 3～5 layers, last tamping is floating.Be as the moulding process of application number 200810119144.3 (prescription of novel halogenide-cumming resistant magnesite greenhouse aggregate and processing technology), application number 01123570.5 (compound booth aggregate prescription of magnesite and processing technology), application number 200810119187.1 employings such as (prescription and the processing technologys of the light body magnesite greenhouse aggregate of novel halogenide-cumming resistant) and divide 4～5 layers of moulding by casting magnesite slip and medium-alkali glass fiber grid cloth; Patent No. ZL99220892.0 (two arch bar greenhouse bracket) adopts two-layer bamboo reinforcement, and three layered materials slurry has some through holes between the last lower arch bar.The work efficiency of these greenhouse bracket its shaping process is all very low, is not suitable for large-scale production, and slip easy-formation is not closely knit.Therefore, the production of magnesite greenhouse support is badly in need of finding the method for effective raising production work efficiency.
Summary of the invention
Purpose of the present invention is that the defective at prior art provides a kind of magnesite composite shed support one-time reinforcing bar-arranging and rapid forming method.
The present invention adopts following technical scheme:
(1) mould of the present invention is made up of inner edge template, outer rim template and tightening card, inner edge template and outer rim template respectively are with an end plate respectively, inner edge template and outer rim template are fixed by 3～7 tightening cards by the end plate positioned in alignment, and mould available metal material or fiberglass are made;
(2) the interior cloth bamboo reinforcement of mould is 4～8, is interted by stainless steel cloth and assembles disposable being installed in the mould in back;
(3) the magnesite composite slurry disposal pouring that stirs is in mould, behind vibratory compaction on the shake table, wipe off, the curing in the mold 8h demoulding in the fog room of 40 ℃ of temperature, relative humidity 60%～70% continues maintenance at room temperature and can come into operation to 7d after the demoulding.
The invention has the beneficial effects as follows:
(1) the greenhouse bracket moulding can be in mould disposable cloth muscle, disposal pouring slurry and adopt vibration moulding, compare shaping efficiency with traditional method and significantly improve;
(2) the mould therefor mounting or dismounting are convenient, not spillage, indeformable, not fragile.
(3) shaped article smooth surface, structure are closely knit, no honeycomb, hole.

Fig. 2 is the cross-sectional configuration figure of Figure 1A-A.
Among the figure, 1. inner edge template 2. outer rim templates 3. tightening cards
Fig. 3 is a bamboo reinforcement layout drawing in the mould.
Fig. 4 is the cross-sectional configuration figure of Fig. 3 B-B.
Among Fig. 3 and Fig. 4,4. mould 5. steel wires 6. bamboo reinforcements
The specific embodiment
Mould can adopt fiberglass to make, and its profile is the quadrant orphan.Inner edge template (1) and outer rim template (2) respectively are with an end plate respectively, and inner edge template (1) and outer rim template (2) are by the end plate positioned in alignment, and be fixing by 4 tightening cards (3).6 bamboo reinforcements (6) are interted by stainless steel cloth (5) assembles disposable being installed in the mould (4) in back, and bamboo reinforcement is evenly distributed in the mould moderate distance.
The compound slip disposal pouring of magnesite composite is gone into to be equipped with in the greenhouse bracket mould of 6 bamboo reinforcements, greenhouse bracket is placed on the shake table of 1000mm * 4000mm, draw together flat behind the vibratory compaction, the curing in the mold 8h demoulding in the fog room of 40 ℃ of temperature, relative humidity 65% continues maintenance at room temperature and can come into operation to 7d after the demoulding.
Claims (3)
1. the one-time reinforcing bar-arranging and rapid forming method of a magnesite composite agricultural shed support is characterized in that:
(1) mould is made up of inner edge template, outer rim template and tightening card, and inner edge template and outer rim template respectively are with an end plate respectively, and inner edge template and outer rim template are fixed by 3～7 tightening cards by the end plate positioned in alignment;
(2) the interior cloth bamboo reinforcement of mould is 4～8, is interted by stainless steel cloth and assembles disposable being installed in the mould in back;
(3) the magnesite composite slurry disposal pouring that stirs is in mould, behind vibratory compaction on the shake table, wipe off, the curing in the mold 8h demoulding in the fog room of 40 ℃ of temperature, relative humidity 60%～70% continues maintenance at room temperature and can come into operation to 7d after the demoulding.
