Abstract

The object is placing inside a female mold which is prepared according to the form/shape of the required glass reinforced cement, an internal thin female mold tray also compressed in the same form; compressing this internal mold tray by spraying GRC mortar in it. After removing excess mortar water from 3 mm diameter holes, which were placed with short intervals on male mold of press, sending of the compressed material along with internal female mold tray to a steam vessel via conveyor belt and steam treating there.

Description

Cement (GRC) sheets/plates that glass is strengthened

The application's theme relates to and is used for making the mould of glass reinforcement cement (GRC) sheets/plates and the method that automated workshop is arranged and made this cement by extruding.

Correlative technology field and prior art situation are as follows.

Adopt many diverse ways to make fiberboard at present.Up to date, in these methods, all adopt asbestos, but brought into use the AR glass fibre now.In making fiber combinations, adopt and the identical method of manufacturing asbestos board.Main method has: Magnani, Hatschek, Procem, Bell and Wellcrete system.They are identical system basically, have only very little difference.Vacuum system by up or down removes too much mortar water, and adopts the cylinder body of major diameter perforation.Yet fiber is strengthened shape or shaping after compoboard can not provide a kind of finishing.In order to make the plate of finishing postforming, must the working pressure machine, and must be in a mould extrded material.But the working pressure machine can not take out the material that presses again from mould.Material must remain to curing in the die of forcing press, both made the employing auxiliary process, for example adopts various curing to quicken chemical substance and heating, and the time of solidifying under best condition also can not be shorter than 5 hours.So just make automation to carry out, and uneconomical.

The scheme that purpose of the present invention and solution comprise the problems referred to above is as follows:

1. the shape that has after finishing and the plate of shaping are provided, and this plate at present can not be by one automatically or the automanual system manufacturing;

2. for this reason, working pressure machine in the process of composition or the manufacturing of fiberboard sheet material,

3. provide automation by use half belt system in the GRC board manufacturing process that adopts extruding,

4. the overlapping and equipped system of the sheets/plates after finishing is provided,, can not on these sheet materials or plate, forms ripple and smooth fiberboard by present technology,

5. with regard to molding mode and subject methods of the present invention, the back side by the sheets/plates after finishing forms muscle provides resistance and intensity, can't make ripple and smooth fiberboard by present system.

Description of the invention

The fiber reinforcement cement sheets/plates that depends on constructional project and design can have any required shape, configuration and details, for example the various pattern wall liners of top board, window post, floor lintel plate, wood appearance, stone material structure, brick structure etc.Can not make standard plate/sheet material after the finishing of this shape/shaping according to present automatic mode.

In our invention, (among Fig. 1-A) one, this indent mould also is squeezed into identical shape/shaping/details (Fig. 2-B) to place thin indent mould in according to the die of desired shape/shaping/details preparation at one.Formation and use and the prior art and dissimilar of indent mould (B) between these moulds, be in the present invention, place the GRC mortar, push and make it combine and make its curing with the indent mould.

By an automatic high pressure spray gun (E) or by spraying (Fig. 5,6,7-C) GRC cement mortar (C) is sprayed in the indent mould of the present invention (B), this indent mould is placed in the die.

Comprise following and the dissimilar feature of prior art according to device for molding of the present invention and manufacture method:

1. in punch, have 2-3mm diameter and 10cm hole (Fig. 4) at interval.From these holes, discharge unnecessary mortar water (dehydration).

By make equipped (Fig. 8-M and Fig. 9-N and L) at interval, ((end concave shape on the inboard of Fig. 4-O) provides required shape, shaping and details to side, equipped part, lap (Fig. 8-M, Fig. 9 N and L) and convex tendon (Fig. 4-O, 11-P) on the surface of the sheets/plates of finishing as punch for Figure 11-P), shaping and details to have the convex tendon of required form.

3. indent mould side is locked (Fig. 5-F) in the side of punch.In this way, when the extruder punch promotes, just can take out thin indent mould (Fig. 3-B and C), be equipped with in this indent mould can with the coarctate GRC mortar of punch.

Extruding punch (after Fig. 5, the 6-D) indent mould (B) is locked in punch (on Fig. 5-F), the too much mortar water of the taking-up hole from punch (Fig. 4).The extruder punch is promoted with locking indent mould thereon, rotate pressure head, be transported to conveyer (Fig. 6) thereby make the convex module band the indent mould.

Open the locking of indent mould, the indent mould that will carry composition, GRC cement plate (C) is discharged on the conveyer (Fig. 7), and is transported to the steam treatment station.

One new indent mould is placed in the die (A), and repeats this process in succession.Mode with a kind of semi-automation is carried out this technology.

A kind of automated workshop also is shown among the figure to be arranged.Empty indent mould (Figure 12-b)) on conveyer, be transported to a spraying station (Figure 12-b), the GRC cement mortar by automatic spray to the interior (Figure 12-C) of indent mould.To fill interior die with the cement mortar of GRC and be placed on die (in Figure 12-d).The whole indent mould that will contain extrded material after extruding is with extruder punch (Figure 12-e) mention.The convex module of extruder travels forward, and arrives the conveyer (top of Figure 12-f).Conveyer will carry the whole indent mould of extrded material, and (Figure 12-g) introduces treatment chamber.
