Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a surface processing method of the ALC (autoclaved lightweight concrete) panel.
[0002]
[Prior art]
The ALC panel is excellent in economic efficiency, light weight, fire resistance and heat resistance, and workability, and is widely used particularly as an outer wall material and partition material of a building. However, ALC panels generally use a manufacturing method in which the raw slurry is semi-cured in a mold, then removed and then cut into a panel shape with piano wire or the like. There was a problem of being scarce. In recent years, there has been an increasing demand for panels having excellent design properties, and various methods for applying a pattern to the panel surface have been proposed.
[0003]
That is, for example, the following methods have been proposed as methods for applying a pattern to the surface of the ALC panel.
(1) A method in which a lightweight foam mortar is placed in a mold, and a rubber mold or sheet with a pattern is placed on the upper surface of the mortar, and the upper surface is rolled with a roller to form a pattern (see Japanese Patent Publication No. 3-27368) ).
(2) A method of forming a pattern by placing a lightweight foam mortar in a mold with a pattern (see Japanese Patent Application Laid-Open No. 8-174525).
(3) A method in which a semi-cured cellular mortar block is cut into a panel shape, and then a pattern having a concavo-convex pattern is pressed against the panel surface to form a pattern (see Japanese Patent Publication No. 5-34121).
(4) A method of cutting the surface of the autoclaved ALC panel with a rotating blade to form a concavo-convex pattern (see Japanese Patent Application Laid-Open No. 58-160106).
(5) A method of forming a recess by causing a projection material such as a small steel ball to collide with the panel surface using an emperor unit (see JP-A-63-25284).
(6) A method of forming an exfoliation band by applying an impact to the edge of the groove formed on the surface of the ALC with an exfoliation tool (see Japanese Patent Application Laid-Open No. 11-148198).
[0004]
However, in the method (1), in order to form various patterns, a mold corresponding to the pattern is necessary, and it is uneconomical to create a pattern for each pattern. In the method (2), the raw material adheres to the mold with the same reason as described above, and it takes time to clean it. The method (3) has the same problems as (1) and (2). Further, although the method (4) is a method usually used in the processing of ALC panels, the design obtained is limited to a mechanically uniform one. The method (5) has problems such as troublesome operations for recovering the projection material such as small steel balls to be used and removing small steel balls remaining in the bubbles of the ALC panel. In the method (6), since the strip is formed from the groove, the processing is limited to the periphery of the groove, and it is difficult to process in a wide area.
[0005]
[Problems to be solved by the invention]
The present invention has been proposed in view of the above problems, and a surface processing method for an ALC panel which can obtain an ALC panel having a high degree of freedom in processing the panel surface and having an economical and natural surface texture. The purpose is to provide.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the surface processing method of an ALC panel according to the present invention has the following configuration. That is, a surface processing method for an ALC panel in which a rough surface is formed on the surface of the ALC panel by scratching the surface of the ALC panel that has been formed in a predetermined size and shape with the processing tool. A plurality of chips made of super steel or diamond having a width of 1 to 5 mm are integrally attached to a support base made of a metal plate so that each has a different size and protruding length. Forming a roughened surface on the panel surface by relatively moving the processing tool and the ALC panel surface in a state where the end of each chip protruding from the support base is in contact with the surface of the ALC panel. It is characterized by.
[0007]
Roughly moving the processing tool and the ALC panel surface, forming a roughened surface on the panel surface while vibrating the processing tool in the thickness direction of the ALC panel, in a direction perpendicular to the relative movement direction, or in both directions. It may be.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
It will be specifically described below based on the surface processing method of the ALC panel according to the invention to the embodiment shown in FIG.
[0009]
FIG. 1 shows an example of an ALC panel produced by the surface processing method according to the present invention. FIG. 1 (a) shows a scratch in the longitudinal direction of the ALC panel 1 (perpendicular to the screen in the figure) by a processing tool to be described later. FIG. 4B shows an example in which the roughened surface 2 is formed at a plurality of positions in the width direction of the panel surface (left and right in the figure). FIG. 5B shows an example in which the roughened surface 2 is formed on the entire surface of the panel 1. ) Is an example in which the scraped rough surface 2 is formed on both sides of the protrusion 4 between the concave grooves 3 formed on the panel surface.
[0010]
In addition, the ALC panel said by this invention means what was obtained by the following manufacturing methods. In other words, mortar slurry in which water and foaming agent are added to calcareous raw material, siliceous raw material, a large number of reinforcing bars are incorporated and injected into the placed mold, and a large block of mold form containing bubbles, that is, during curing The semi-plastic body was cut with a piano wire or the like and cured by autoclaving. This ALC panel may be of any shape as long as it is obtained by the above method and contains bubbles, such as a flat panel used as an outer wall of a building, a floor, a roof, a partition material, etc. There are corner panels such as L-shaped cross sections used for corners of outer walls and the like.
[0011]
In order to manufacture the ALC panel having the scraped rough surface 2 as described above, for example, the panel surface is processed by scratching with a dedicated processing tool. As the processing tool 5 to be used, for example, as shown in FIG. 2, a plurality of chips 6 made of super steel, diamond or the like are integrally attached to a support base 7 such as a metal plate by welding or bonding. can do. These chips 6 have a width of about 1 to 5 mm in the present embodiment, and are attached to the support base 7 so that the protruding lengths thereof are different.
[0012]
In order to form the roughened surface 2 as described above on the panel surface using the processing tool 5 as described above, for example, the processing tool 5 is formed on the surface of the ALC panel 1 at a depth to be processed as shown in FIG. The surface of the applied ALC panel 1 may be relatively moved at a predetermined speed to scratch the panel surface. If the scratch processing is performed at a predetermined interval in the width direction of the panel, as shown in FIG. A panel as shown in FIG. 1B can be obtained by scratching the entire surface of the panel.
[0013]
The scraped rough surface 2 obtained by the above-described scratching process has a surface texture in which a part of the bubbles are exposed by crushing the lightweight cellular concrete and the surface of natural stone is scraped off. Moreover, the surface texture exhibits a surface property that is clearly different from the state of the panel surface cut using the piano wire or the like.
[0014]
Note that the processing tool 5 may appropriately change the angle applied as shown in FIG. 4 in the range of about 30 degrees to 150 degrees with respect to the traveling direction. Texture). Further, when the processing tool 5 is moved relative to the panel surface, as shown in FIG. 5, for example, in a cycle of about 1000 to 10,000 times per minute, the vertical direction (panel thickness direction) or the horizontal direction (relative processing tool) If machining is performed while reciprocating (vibrating) in both directions (perpendicular to the moving direction) or both directions, the cutting ability is improved and a fine wavy rough surface is obtained.
[0015]
Further, as shown in FIG. 6, a groove 3 is formed in advance on the surface of the panel 1, and a protrusion 4 simulating a tile or the like is formed between adjacent grooves 3, 3 along both side edges of the protrusion 4. If the processing tool 5 as described above is subjected to scratching by relative movement at a relative speed of 5 m / min, for example, a panel as shown in FIG. 1C is obtained.
[0016]
The above embodiment is an example, and the area to be scratched by the processing tool 5 can be appropriately changed, whereby an ALC panel having the roughened surface 2 in a desired area is obtained. Further, the structure, size and shape of the processing tool 5 can be changed as appropriate.
[0017]
