ルを、高い生産性で製造することが可能となる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a lightweight cellular concrete panel having a decorative finish on the panel surface. [0002] Lightweight cellular concrete panels are excellent in economical efficiency, lightness, fire resistance and workability, and are widely used especially as exterior wall materials for buildings. However, lightweight cellular concrete panels are generally manufactured using semi-hardening of raw materials in a mold, followed by demolding and cutting into panels using piano wire or the like. There was a problem that the surface design was poor. As a method of improving the pattern, a method of forming a pattern on the panel surface is as follows: (1) A semi-cured cellular mortar block is cut into a panel shape, and a mold having an uneven pattern is pressed against the panel surface to form a pattern. Method (Japanese Patent Publication No. 5-34)
121 has been proposed. According to this method,
There is an advantage that a freely designed pattern including a curve can be manufactured with high productivity. Further, (2) a method of projecting hard particles on the surface of the lightweight cellular concrete panel to form an uneven pattern on the surface, and then forming a groove by cutting on the surface of the lightweight cellular concrete panel ( Tokuhei 4-78083
Has also been proposed. However, in the above technique, in the method (1), a mold having an uneven pattern is pressed against a semi-cured panel surface to form the uneven pattern. When removing the decorative mold, the uneven parts perpendicular to the panel surface, such as tile joints, are less likely to be removed than other relatively smooth patterned surfaces, and the mortar is peeled off together with the decorative mold However, it is easy to cause a so-called poor mold release, and the poor mold release lowers the product yield and lowers the productivity. To prevent this, if the vertical part of the joint is tapered and a makeup mold that is relatively easy to remove is used, the pattern to be formed does not have the edge of the joint, so the overall uneven pattern is sharp There was a problem that did not give the impression of. Further, generally, the deepest portion of the uneven pattern is a joint or a groove in a tile or a brick tone. When the uneven portion of the pattern is deep, a heavy portion generated when the semi-cured panel is pressed. The pressing force exerted on the panel affected the reinforcing material inside the lightweight cellular concrete, causing the reinforcing material to be distorted and easily causing cracks in the panel during molding or aging. In the method (2), it is possible to form a pattern groove with a relatively deep edge by cutting, but the portion cut by the blast material becomes a rough surface, and Since the surface strength is weak, there is a problem of powder dropping. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for manufacturing a lightweight cellular concrete panel having a concave-convex pattern having a clear and deep groove including a curved surface with high productivity. [0008] As a result of intensive studies to solve the above problems, the present invention has been accomplished. That is, the present invention presses a decorative mold having an uneven pattern onto a semi-cured cellular mortar panel to form an uneven pattern, then cures and cures, and forms a fine pattern groove by cutting on the hardened uneven pattern surface. The present invention relates to a method for producing a decorative lightweight cellular concrete panel. Embodiments of the present invention will be described below in more detail. In the present invention, a semi-cured cellular mortar panel can be obtained by cutting a semi-cured cellular mortar block into a panel shape. The method of cutting the semi-cured cellular mortar block into a panel is not particularly limited, and may be a method used for cutting ordinary lightweight cellular mortar. For example,
Use a method of cutting a semi-cured lightweight cellular mortar block with a tensioned wire such as a piano wire, or a method of cutting with a plurality of tensioned wiring materials to obtain a plurality of panel-shaped semi-cured products. Can be. The raw material of the cellular mortar block is not particularly limited as long as it is generally used as lightweight cellular concrete. For example, a mortar slurry containing silica stone, cement, quicklime, water as a main raw material, and gypsum, a foaming agent, crushed debris, and the like added as necessary can be used. As a method of mixing bubbles, a method of mixing a foaming agent into a mortar slurry to cause foaming, or a method of mixing bubbles that have been foamed in advance into the mortar slurry may be used. The semi-cured cellular mortar block of the present invention is obtained by injecting the cellular mortar slurry obtained as described above into a form in which reinforcing bars are arranged in advance, curing, and then having a hardness suitable for cutting. , By removing it from the mold. In the present invention, the decorative mold is a mold having an uneven pattern used for imparting an uneven pattern to the semi-cured mortar. The material of the decorative mold is not particularly limited as long as it has a strength capable of transferring a pattern to a semi-cured panel. For example, hard urethane rubber, hard plastic, styrene foam, steel, stainless steel, aluminum, titanium, etc. Can be used. In particular, hard urethane rubber, hard plastic, and metal are preferable in terms of pattern accuracy and durability. The decorative pattern of the decorative mold is not particularly limited. For example, a stone pattern, a brick pattern, a tile pattern, and the like are often used. Brick tone, deep straight portion of the joints in the pattern of tile tone, etc., after curing, after curing, because it is formed by cutting, it is not particularly necessary to provide in the decorative mold, it is formed by pressing semi-cured mortar Since the heavy portion serves as a reinforcement for the end of the pattern groove at the time of cutting or after cutting, it is preferable to provide a shallow uneven groove at a portion corresponding to the cut groove. The method of pressing the semi-cured mortar-like panel with a decorative mold having a concavo-convex pattern is not particularly limited, but first, a contact plate is applied to a surface in all directions except the surface on which the concavo-convex pattern is pressed. Next, a method of pressing a decorative mold having an uneven pattern against the semi-cured panel by pressing it against the semi-cured panel is preferable because cracking or chipping of the panel end at the time of pressing can be prevented. Here, the hitting plate is used to hold the surface of the semi-cured panel in all directions other than the surface on which the decorative mold is pressed, when the uneven pattern is formed on the semi-cured panel. Examples of the backing plate include a bottom plate on which the semi-cured panel is placed, and an outer mold frame around the semi-cured panel placed on the bottom plate. The material of the backing plate is not particularly limited as long as it has strength and durability that can hold the surface of the semi-cured panel, for example, hard urethane rubber,
Hard plastic, styrene foam, steel, stainless steel, aluminum, titanium and the like can be used. By pressing during semi-curing, the air bubbles in the pressed portion are crushed and heavier, so the strength of the panel pattern surface is increased, and chipping of the end of the pattern groove at the time of cutting or after cutting is prevented. Can be. The semi-cured panel having the uneven pattern surface formed by pressing is cured and cured to obtain a cured panel 1 provided with the uneven pattern by the decorative mold 2 as shown in FIG. Thereafter, pattern grooves are formed by cutting, and a decorative lightweight cellular concrete panel 4 having clear and deep grooves 3 as shown in FIG. 2 is obtained. The method for curing and curing the semi-cured panel is not particularly limited, and a method for curing ordinary lightweight cellular concrete can be used. For example, normal pressure steam curing, autoclave curing, underwater curing and the like can be mentioned. As a method of forming a fine pattern groove on the cured pattern panel surface, a method by cutting is used, and examples thereof include a normal milling machine and an NC processing machine. The width of the fine pattern groove may be freely determined in consideration of the design property, etc., but especially in the case of a deep groove, the heavy layer on the surface may be cut off, and powder may fall off from that portion. Therefore, it is preferable that the groove width is narrow from the viewpoint of powder dropping. On the other hand, if the groove width is too small, the groove becomes inconspicuous and the design property is reduced. Therefore, the width of the narrow groove is 1 to 30 mm
Is more preferable, and the range of 2 to 15 mm is more preferable. EXAMPLES The method for producing a decorative lightweight cellular concrete panel of the present invention will be described below with reference to examples. Example 1 53 parts by weight of silica stone, 7.5 parts by weight of quick lime, 37 parts by weight of cement, 2.5 parts by weight of dry gypsum, 68 parts by weight of water and 0.060 parts by weight of aluminum powder based on 100 of these solid contents 5 parts of lightweight cellular concrete mortar containing
50 × 550 mm metal lath mesh (mesh size 16 × 32 m
m, 0.8 mm in thickness) was placed into a mold, and a cured mortar block in the latter half of curing was obtained. The mortar block was cut with a piano wire to obtain a 37 × 600 × 600 mm test piece having a metal lath net disposed at the center. This test body was placed in a 50 × 600 × 600 mm steel mold, and a decorative mold to which a release agent was applied was placed from above, and 2 k
It was pressed 4 mm at a pressure of g / cm @ 2. The makeup mold was made of hard urethane rubber with a maximum pattern depth of 4 mm and a sandstone tone. After pressing, the mold was removed from the mold, and a lightweight cellular concrete panel obtained by curing in an autoclave was formed with a groove having a depth of 10 mm and a width of 5 mm using a milling machine.
The obtained lightweight cellular concrete clearly copied the pattern of the decorative mold used, and further had a groove with a deep edge, and no peeling, chipping, or chipping of the pattern groove was observed. . The cut surface had a high specific gravity due to the collapse of air bubbles only in the surface corresponding to the decorative pattern of the decorative mold at the time of pressing, and the other portions were the same as a normal lightweight cellular concrete section. Comparative Example 1 A lightweight mortar similar to that in Example 1 was previously placed in a 550 × 550 mm metal lath net (mesh size 16 × 32).
(mm, 0.8 mm in thickness) was placed into a mold, and a cured mortar block in the latter half of curing was obtained. The mortar block was cut with a piano wire to obtain a 37 × 600 × 600 mm test piece having a metal lath net disposed at the center.
This test body was placed in a 50 × 600 × 600 mm steel mold, and a decorative mold coated with a release agent was placed from above,
A 10 mm press was performed at a pressure of kg / cm @ 2. The decorative mold is made of hard urethane rubber and has a maximum pattern depth of 4 mm in a sandstone tone with a width of 5 m so that a groove with a depth of 4 mm is formed after pressing.
m, and without a taper,
A groove perpendicular to the decorative surface was formed. At the time of demolding after pressing, a large number of peelings and chips occurred on the edges of the groove of the test piece. Comparative Example 2 37 × 60 obtained by the same method as in Example 1.
50 × 60 semi-cured cellular mortar panels of 0 × 600
Placed in a 0 × 600 mm steel mold, a makeup mold coated with a release agent is placed from above,
mm. The makeup mold is made of hard urethane rubber and has a maximum pattern depth of 4 mm in a full sandstone style, and a depth of 10 mm after pressing.
A 5 mm wide convex portion having a 1/20 taper so as to form a groove was formed. After pressing, cracks occurred in the grooves of the test piece, which were considered to be caused by distortion of the metal lath net. According to the present invention, it is possible to manufacture a lightweight cellular concrete panel having a concave and convex pattern including a clear and deep groove including a curved surface with high productivity.
