この発明は強化セメント薄板の成形方法及びその装置に
関し、更に詳しくは強化材としてガラス繊維等の短繊維
を使用せる強化セメント薄板の成形方法及びその装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for forming a reinforced cement thin plate, and more particularly to a method and apparatus for forming a reinforced cement thin plate using short fibers such as glass fibers as a reinforcing material.
従来、強化セメント薄板の成形は画状の型枠内にモルタ

付け器によって吹き付け、吹き付け後ローラーで平に均
し、再び上記の作業を行なって所定の厚さになるまで積
層するといった方法が採られていた。Conventionally, to form reinforced cement thin plates, mortar and reinforcing fibers cut into short fibers were sprayed into a picture-shaped formwork using separate sprayers, and after the spraying, they were leveled with rollers and the above process was repeated. The conventional method was to stack the layers until they reached a predetermined thickness.

結果強度も不揃いになるといった不具合を有していた。However, in the above method, each sheet is molded one by one, which results in a lack of work efficiency and makes it impossible to produce large quantities.In addition, the mortar and reinforcing fibers are mixed unevenly, resulting in uneven strength. It had problems such as:

て取付けたことを要旨とするものである。Therefore, the present invention was made to solve the drawbacks and inconveniences of the conventional method as described above. A thin plate forming part is formed between the flat plates by joining and tightening them in a shape,
On the other hand, short fibers of reinforcing fibers are sprayed onto the mortar flowing out from the outlet of the hopper onto the guide plate, and vibration is applied to create a uniformly mixed fiber mortar. This is a method for forming a reinforced cement thin plate by pouring it in small quantities into the molding section by moving the cement, and hardening it. A plurality of forming molds made by attaching flat plates to the side surfaces of a thin frame body formed in the shape of a sun and having engagement protrusions on both sides of the upper end are vertically suspended. , a frame supporting a hopper is mounted so as to be movable, an adjustment plate is attached to the outlet of the hopper to adjust the opening degree of the outlet, and a vibrating guide plate is placed below the outlet and tilted downward on the frame. The main idea is that the fiber spraying device is installed on a pedestal with the fiber spraying device facing the guide plate.

づつ流し込みて薄板を成形するものである。In the molding method according to the present invention, the mortar from the hopper flows out to a guide plate that guides it into the mold, and reinforcing fibers cut into short fibers are sprayed onto the mortar, and the guide plate is vibrated to keep the reinforcing fibers mixed. A thin plate is formed by making the hopper uniform and reciprocating the hopper and guide plate together, and pouring it little by little into a set of molds made up of a thin frame with a sun-shaped cross section and a mold attached to one side of the frame. It is.

できるものである。In the method of the present invention, the amount of mortar flowing out from the hopper onto the guide plate is controlled by operating the adjustment plate attached to the outlet of the hopper to adjust the opening degree of the outlet. The blending ratio with the reinforcing fibers sprayed into the mortar can be optimized, and since the reinforcing fibers are mixed in after coming out of the hopper, the reinforcing fibers are mixed into the mortar in the hopper in advance and flowed out from the outlet. Problems such as poor mortar flow that occur when using this method can definitely be resolved.

On the other hand, short fibers of reinforcing fibers are sprayed onto the mortar flowing out from the outlet of the hopper onto the guide plate.
The fiber-filled mortar is made into a uniformly mixed state by applying vibrations, and the fiber-filled mortar is poured little by little into the molded area by reciprocating the hopper and guide plate, and is hardened. It is possible to provide a method that can efficiently form a reinforced cement thin plate with uniform strength and uniform fiber blending.
