Dispense in a fixed amount. On the other hand, ultra-fast hardening cement and water are mixed in the tank 24 and sent to the metering pump 25, which adjusts the discharge amount to an arbitrary discharge amount using the adjustment knob 26 and discharges the cement at a constant rate. A hardening accelerator (setter) for adjusting the hardening time of the ultra-fast hardening cement is mixed with water in a tank 27 and sent to a metering pump 28, and the pump 28 is adjusted to an arbitrary discharge rate with an adjustment knob 29 and discharged at a constant rate. The regular cement mortar, ultra-fast hardening cement, and setter that have been discharged in fixed amounts are mixed and stirred in a mixer 30 to produce mortar containing ultra-fast hardening cement. This mortar 31 is charged onto layer c by a charging device E provided on a cart 33 that reciprocates in the width direction of the conveyor A along a rail 32 provided above the conveyor A. A mortar injection hose 34 is attached to the above-mentioned truck so as to be adjustable in the vertical direction. A thickness adjusting device 35 is provided immediately after the mortar injection point, whereby the thickness of the mortar 31 is kept constant to form the deposited layer d. A lower vibrator 36 is provided below the belt 1 facing the adjustment device 35, and its vibration causes the mortar 31 to penetrate into the glass fiber layers B and C on the belt.

The pump 25 adjusts the discharge amount to an arbitrary discharge amount with the adjustment knob 26 to discharge a metered amount, and the pump 22 discharges the metered amount. Mortar 31 containing ultra-fast hardening cement is mixed and stirred with ordinary cement mortar in mixer 30.
I can do it. The mortar 31 is loaded onto the conveyor 1 by the loading device E, and is adjusted by the adjustment knob 26 of the metering pump 25 depending on the hardening state of the mortar 31 and the hardening time. However, tank 24
The best combination of ultra-fast hardening cement and setter is determined through experiments, and the curing state and curing time are slightly adjusted using the adjustment knob 26. In this case, there is also a method of manufacturing without using the setter tank 27 and metering pump 28.

Similarly, the carriage 40 reciprocates along the rail 41 in the width direction of the conveyor A, and a roving cutter 42 is attached to the carriage 40 so as to be adjustable in the vertical direction. Reference numeral 43 denotes a glass fiber roving, and this roving 43 is cut into short pieces by a cutter 42 and sprayed onto layer e as short fibers 43'. This is called the f layer. The laminate stacked as described above is then moved to an upper vibrating body 4 provided above the belt 1.
The mortar 31 penetrates into the glass fiber layers e and f on the upper surface by the vibrations of 6 and 46', and the e and f layers form an upper layer, and a mixture of ordinary cement mortar and ultra-fast hardening cement is formed between the lower layer and the lower layer. Adhesive sandwiching the intermediate layer consisting of the following. Further, a lower vibrating body 47 is provided on the lower side of the belt 1 facing the upper vibrating bodies 46, 46', and vibrates so that the mortar 31 further penetrates into the lower and upper layers of glass fibers. It's summery. The top surface of the upper layer is further finished by a finishing plate 49 which is supported by a fixed beam 48 and can freely rotate and move up and down, forming a flat laminate of the desired thickness as shown in FIG. .

The support plates 5, 5' are loosely fitted into the support plates 5, 5', and tapered portions 51, 51' are formed at the front end edges of the support plates 5, 5' to be inclined downward. When forming, the flat laminate that is guided by the rising parts 3a, 3a' on the belt 1 and the support plates 5, 5' is directed as it is to the position where the tapered parts 51, 51' are formed. This allows the laminate to move along the tapered portions 51, 51' on both sides of the laminate into the grooves 3, 51'.
While contacting the inner surface of 3', it gradually falls into the grooves 3 and 3' due to its own weight, and as shown in Figures 3 and 5, it sag slightly inward at point A and fold as shown in Figure A. Bend. And this bending is the taper part 51,
51', and when it finishes descending the tapered parts 51, 51', it is further bent outward through the bottom corners of the concave grooves 3, 3', and at point B, it becomes larger. As shown in the figure, the entire body is formed into an inverted U-shaped cross section. During the above-mentioned molding, the laminate has tapered portions 51, 51' on the surface of the intermediate portion.
Finishing rollers 52 disposed in between and close to the belt surface form a tapered portion 5 on both sides of the surface.
Finishing rollers 53, 5 disposed within the downstream grooves 3, 3' of the grooves 1, 51' and close to the bottom surface of the grooves.
3' further provides finishing rollers 54, 54' whose outer surfaces on both sides are disposed close to the inner surface of the groove.
Surface finishing is performed in sequence.

る。 This invention is as described above, in which grooves are formed on both sides along the longitudinal direction of the surface, and a fixing member is loosely fitted onto the running endless belt with its surface substantially flush with the groove. A laminate is formed by supplying long and short fibers and a mixture of ordinary cement mortar and ultra-fast hardening cement, and this laminate is formed in a downward slope on the front edge of the fixing member located at the front in the running direction of the belt. When passing through the taper, both sides are bent downward to form an approximately inverted U-shaped cross section, and then harden, allowing glass fiber reinforced cement boards with an approximately inverted U-shaped cross section to be formed continuously in a short period of time. can be manufactured and its productivity can be increased. Further, because of continuous manufacturing, it has excellent effects such as being able to provide a high quality product without variations in material layer thickness.
