Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for manufacturing foamed cellular concrete panels (hereinafter referred to as ALC boards), particularly wide panels, in which lightweight cellular concrete is in a semi-plastic state (hereinafter referred to as ALC boards). The present invention relates to a double-sided cutting device for a lightweight cellular concrete semi-plastic body, which can cut one or both sides of a single panel at the same time and with accurate finishing dimensions.

[Conventional technology and problems]

ALC boards are widely used as building materials due to their light weight and heat insulation properties.

However, conventionally, when manufacturing ALC boards,
For example, reinforcing bars are placed at predetermined positions in a 3m x 1.5m deep 0.6m formwork, lightweight aerated concrete raw material is injected, and when the raw material slurry becomes semi-plastic, it is removed from the formwork and surfaced. After cutting the
75mm while moving a support frame with vertically stretched steel wires.
After curing and curing in an autoclave, a semi-plastic body of 3 x 0.6 x (0.075 to 0.15) m, cut to a specified thickness of about 150 mm and 0.6 m wide, is chamfered. , grooves were processed and the product was made into a product.

On the other hand, in recent years, with the expansion of its uses, there has been demand for ALC boards of various sizes, such as 3 x 1.5 x
Wide plate materials such as 0.15m are now required. When manufacturing this plate material, a conventional formwork is used to create a semi-plastic body with a thickness of 3 x 1.5 x 0.2m, the formwork is removed, the surface is cut, and then the material is turned 180 degrees. Either the back surface is cut to a predetermined size and then hardened, or only the front surface is finished by cutting, and the back surface is hardened and then finished cut to a predetermined size.

However, these methods not only take a long time and increase costs, but also make it difficult to invert a thin semi-plastic body without deforming it, and it is difficult to improve the accuracy of finished dimensions. In addition, there were also problems with the quality of the product, such as the corners of the back surface being easily damaged.

[Means for solving the problems] The present inventors have solved these problems and developed a wide range of
We have conducted extensive research to create a device that can easily and precisely cut both sides of an ALC plate at the same time.We have developed a device that supports the four sides of the semi-plastic body vertically in the thickness direction with a support frame that is slightly thinner than the desired dimensions, and performs vertical cutting. Recognizing that it is possible to cut the plate surface with a blade and finish it to the desired dimensions in one process,
A suitable device has been developed. That is,
In order to form a semi-plastic body by injecting and foaming a lightweight aerated concrete raw material, the present invention provides a casting mold constructed by combining a channel formwork whose width is narrower than the thickness of the semi-plastic body by the cutting allowance. a frame, a support frame mechanism that vertically supports the semi-plastic body while it is cast in the casting mold, and is formed to have a thickness slightly thinner than the thickness of the semi-plastic body, and a vertical cutting mechanism. A plate surface cutting device for a lightweight aerated concrete semi-plastic body comprising a cutting mechanism provided with a blade and a mechanism for relatively moving the two mechanisms so as to cut at least one plate surface of the semi-plastic body. .

Of course, this is possible and there is no problem. Further, in the illustrated embodiment, an example was explained in which both sides of the semi-plastic body are cut at the same time, but it is of course possible to cut only the other plate surface, such as when one plate surface is cast with an uneven pattern.
