Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to the design panel having a crushing surface.
[0002]
[Prior art]
The lightweight cellular concrete panel is a lightweight ready-made panel reinforced with reinforcing reinforcing bars and the like, and is known as a large panel having a width of 60 cm and a length of several meters, for example. This lightweight cellular concrete panel has the characteristics that it is economical, lightweight, fireproof and heat resistant, and excellent in workability. In the building industry, it is a private house, a house with a store, a roof of a building, a floor, an outer wall, and It is often used as a partition material.
[0003]
However, lightweight cellular concrete panels are materials with excellent properties in this way, but they are generally produced as panels with flat surfaces in terms of production efficiency, so they are poor in design when used as exterior wall materials. There is a problem. Therefore, conventionally, in order to overcome this problem, a method for obtaining an uneven pattern on the surface of the lightweight cellular concrete panel has been proposed. For example, in order to obtain a pattern surface as disclosed in JP-A-9-157056, there is a technique in which a decorative mold is pressed against a semi-cured panel to give a pattern, and then autoclaved.
[0004]
In addition, Japanese Patent Publication No. 3-29749 has a method in which the surface of a lightweight cellular concrete panel is processed with a projection material in order to obtain a processed surface. Furthermore, Japanese Patent Laid-Open No. 11-246276 has a technique characterized in that a press surface and a crushing surface are formed at arbitrary positions on the surface of the lightweight cellular concrete panel.
[0005]
[Problems to be solved by the present invention]
As shown in FIG. 6, in order to obtain a pattern surface 10 as disclosed in Japanese Patent Laid-Open No. 9-1557056, there is a technique in which a decorative mold 9 is pressed against a semi-cured panel 15 to give a pattern, and then autoclave curing is performed. The resulting surface texture is high specific gravity and smooth because the bubbles are crushed, so that the impression given to the sight is smooth, without graininess or fine shadows. In addition, in order to make it easier to remove the decorative mold 9 after pressing the decorative mold 9 after pressing the decorative mold 9 with a technique of applying a pattern by pressing the decorative mold 9 against the semi-cured panel 15 and then curing the autoclave. A draft 11 of about / 20 was generated, and the pattern surface 10 was not provided with a significant difference in height. Furthermore, when creating several types of patterns, it is necessary to prepare several types of decorative molds 9 and replace them, so that the production efficiency is poor.
[0006]
In addition, in Japanese Patent Publication No. 3-29749 shown in FIG. 7, the surface of the lightweight cellular concrete panel is processed with a projection material in order to obtain the processed surface 13, and the processed surface 13 is exposed to air bubbles on the surface of the lightweight cellular concrete panel. It becomes a surface. Since the processed surface is obtained by a projection material projected along various trajectories by the rotation of the impeller unit, it becomes a relatively smooth surface, and the non-processed surface 12 that does not receive such processing is arranged in a plane, Since the pattern was formed, the processing surface 13 was not provided with a significant difference in elevation. Furthermore, a template with a notch in the shape of a pattern is placed on the surface, and the projection material is projected toward the surface of the template. Therefore, when creating several types of patterns, prepare several types of templates and replace them. Production efficiency is poor because it is necessary.
[0007]
Further, Japanese Patent Application Laid-Open No. 11-246276 shown in FIG. 8 is characterized in that the press surface 14 and the crushing surface 4 are formed at arbitrary positions on the surface of the lightweight cellular concrete panel, and the portion where the cut surface of the cell is exposed as it is. Therefore, the surface texture obtained can be a natural-tone design and an arbitrary pattern on the pressing surface 14 and the crushing surface 4 having a complicated and gentle gradient. there were. That is, in JP-A-11-246276, the press surface 14 and the crushing surface 4 have a gentle gradient to the last. An object of the present invention is to solve the above problems and provide a design panel having clear contrast and natural tone texture.
[0008]
[Means for Solving the Problems]
That is, the present invention achieves the above-mentioned problems and is as follows .
[0009]
1 . A lightweight cellular concrete panel having a crushing surface on the surface, and having a surface processed portion with a significant difference in height between adjacent crushing surfaces, and the boundary between adjacent crushing surfaces is a surface substantially perpendicular to the surface. lightweight cellular concrete design panel said that there.
2 . 1 substantially vertical plane characterized in that it is a crushing surface. Lightweight cellular concrete design panel as described .
[0010]
Hereinafter, the present invention will be described in detail. First, the example of the surface external appearance of the lightweight cellular concrete panel of this invention is typically shown in FIGS. The lightweight cellular concrete panel in the present invention refers to one obtained by the following production method. For example, a mortar slurry in which water, a foaming agent, etc. are added to a calcareous raw material or siliceous raw material is injected into a mold having a large number of reinforcing bars, and a large block of a mold containing foam is semi-cured during curing. In this state, it was cut with a piano wire and cured by autoclaving.
[001 1 ]
The lightweight cellular concrete panel referred to in the present invention includes any shape as long as it contains bubbles, and is used for a floor of a building, a flat panel used as a partition material, and a corner of an outer wall. Examples include L-shaped and R-shaped corner panels, the shape of reinforcing bars, and those manufactured to a predetermined shape by cutting the panel after autoclave curing. The surface property of the crushing surface in the present invention includes a portion where the cut surface of the bubble is exposed as it is and a heavy layer that is crushed, and the impression given to the visual sense is that the surface is formed by fine particles, It has a fine shadow.
[001 2 ]
The adjacent crushing surface in the present invention refers to a surface in which the crushing surfaces described above are located in parallel as viewed from the surface cut by the piano wire of the lightweight cellular concrete panel and the crushing surfaces are adjacent to each other. . In addition, the surface processed portion having a significant difference in height between adjacent crushing surfaces is the distance from the adjacent crushing surfaces in the vertical direction when viewed from the plane where the adjacent crushing surfaces are cut with a lightweight cellular concrete panel piano wire. The surface processed part where the difference of is remarkable is said. Furthermore, the height difference of 5 mm to 20 mm means that the distance difference is 5 mm to 20 mm. In this case, the range of the height difference is preferably 5 mm to 20 mm, more preferably 7 to 20 mm in terms of design.
[001 3 ]
In the present invention, the substantially vertical surface means that the boundary portion between the adjacent crushing surfaces is approximately 80 degrees to 100 degrees in the direction cut by the piano wire of the lightweight cellular concrete panel as viewed from the surface processed portion. The vertical surface is a crushing surface, and the substantially vertical surface is the crushing surface. In the present invention, the crushing surface shape of the crushing surface shape is generally similar, the degree of crushing surface is similar at a level of a wide shadow formed continuously at the boundary between crushing surfaces, and certain constant This means the surface processed part where the pattern is formed. Further, the fact that the shape of the crushing surface in the present invention is inconsistent in detail means that there is a difference in the degree of the crushing surface with a granular feeling formed by fine particles on the surface of the crushing surface and a fine shading level.
[001 4 ]
In the present invention, since a significant difference in height is provided between adjacent crushing surfaces, a wide shadow can be continuously formed at the boundary portion between the crushing surfaces, and the boundary between the crushing surfaces is clearly distinct. That is, to obtain a unique surface property that is dynamic and full of emotion by adjoining the crushing surface with a grainy texture and fine shadow (formed by fine particles on the surface) across the boundary. Became possible for the first time. Furthermore, in addition to the above-described configuration, it is possible to further clarify the wide shadow formed continuously on the boundary between the crushing surfaces by configuring the boundary between adjacent crushing surfaces with a substantially vertical surface. Thus, it becomes possible to obtain a unique surface texture that is more dynamic and full of emotion.
[001 5 ]
In addition, by configuring the substantially vertical surface with a crushing surface, the graininess formed by the fine particles on the crushing surface surface and the fine shading are continuously formed at the boundary between the crushing surfaces described above. It is possible to give it to a wide shadow itself, and it is possible to express a natural texture on the whole, including the boundary part between adjacent crushing surfaces, while it is a unique surface property that is dynamic and full of emotion. Become.
[001 6 ]
Furthermore, in addition to the above configuration, a pattern surface processed portion having a generally similar crushing surface shape of the surface processed portion is provided in two or more portions, so that unity (unification) and repetition (repetition) , Wall material with a unique surface property that is dynamic and full of emotion, utilizing the principles of beauty such as symmetry (target), balance, harmony, proportion (ratio), contrast (contrast) It becomes possible to express the unified beauty as.
[001 7 ]
Furthermore, the impression of a uniform industrial product that the surface texture repeats almost exactly the same machining shape by making the crushing surface shape inconsistent in detail in the corresponding portions of the two or more pattern surface machining portions. It is possible to obtain a surface texture that has a natural feeling with irregularities and randomness in so-called details. The rod-shaped impact tool in the production of the lightweight cellular concrete design panel of the present invention is capable of providing a significant difference in height between adjacent crushing surfaces, for example, multi-needle chisel, single-needle chisel, needle, nail, Examples include needles and hammers.
[00 18 ]
The working depth in the production of the lightweight cellular concrete design panel of the present invention is the depth in the vertical direction when viewed from the surface of the lightweight cellular concrete panel cut by the piano wire when the rod-shaped impact tool is operated. The number of hits in the production of the lightweight cellular concrete design panel of the present invention is the number of times the surface of the lightweight cellular concrete panel is struck with a rod-shaped impact tool. The striking strength in the production of the lightweight cellular concrete design panel of the present invention is an impact force when striking the surface of the lightweight cellular concrete panel with a bar-shaped impact tool.
[00 19 ]
In the manufacture of the lightweight cellular concrete design panel of the present invention , the tip portion of the bar-like impact tool is planarly blurred. When the rod-like impact tool is actuated, the tip portion is cut with the piano wire of the lightweight cellular concrete panel. This means that there is a blur in the horizontal direction when viewed from the surface, and this blur has a degree of irregularity and randomness in the fine crushing process.
[002 0 ]
Here, the manufacturing method of the lightweight cellular concrete design panel of this invention is demonstrated easily. By operating the bar-shaped hammering tool at an arbitrary working depth according to the position of the panel surface, the bar-shaped hammering tool is adjacent to each other by providing a height difference in the working depth at two adjacent positions on the lightweight cellular concrete panel surface. A significant difference in height can be provided between the crushing surfaces, and the boundary between adjacent crushing surfaces can be a substantially vertical surface. Furthermore, depending on the position of the panel surface, any operating depth or operation Since it is possible to adjust the crushing surface height by operating with strength, it is also possible to provide a pattern surface processing part in which the crushing surface shape of the surface processing part is generally similar in two or more parts Become. In addition, it is only necessary to control the operation of the impact tool for manufacturing, and since the crushing surface pattern can be formed without using and replacing the decorative mold or template, the production efficiency is very good, and it is dynamic and emotional. Overflowing unique surface properties can be formed, and it is also possible to express a unified beauty as a wall material.
[002 1 ]
Further, it is possible to provide a difference in height between adjacent crushing surfaces at a constant operating depth by increasing or decreasing the number of times of hitting the rod-like hitting tool or by operating the hitting strength with a certain level of strength. Further, by configuring the tip of the rod-shaped hitting tool to be flat in plan, even if the working depth, the number of hits or the hitting strength of the hitting tool are the same, irregularities in detailed crushing processing -It becomes random and can manufacture the lightweight aerated concrete panel in which the shape of a crushing surface does not correspond in detail in the corresponding part of two or more said pattern surface process parts.
[002 2 ]
[Example 1]
As shown in FIG. 1, a bar-shaped impact tool was operated at an arbitrary position on the surface of a lightweight cellular concrete panel having a thickness of 12.5 cm, a width of 60 cm, and a length of 200 cm to perform surface processing. As a result, a design panel having a surface processed portion having a height difference of 5 mm between adjacent crushing surfaces was obtained.
[002 3 ]
In addition, a wide shadow can be continuously formed at the boundary part between the crushing surfaces, the boundary between the crushing surfaces is clearly distinct, and the graininess and fineness (formed by fine particles on the surface) Since the crushing surface having a smooth shadow as a surface property is adjacent to the boundary, a unique surface property that is dynamic and full of emotion can be obtained. Furthermore, since the boundary between the crushing surfaces is a substantially vertical surface and a crushing surface, it is possible to further clarify the wide shadow formed continuously on the boundary between the crushing surfaces. We were able to obtain a unique surface texture overflowing with. In addition, the pattern surface processing part, which is similar in shape to the crushing surface of the surface processing part, is provided in two or more parts, so that repetition (repetition), balance (balance), harmony (harmony), proportion ( Taking advantage of the formal principles of beauty such as ratio and contrast, it was possible to express the unified beauty as a wall material, despite the unique surface properties that are dynamic and full of emotion.
[002 4 ]
When eight lightweight lightweight concrete panels with such surface processing were prepared and stacked, and impact tests were conducted, no chipping or cracking occurred at the side of the edge of the groove. Was maintained. Next, a coating test and a construction test were performed on all of the obtained lightweight cellular concrete panels. As a result, there is no paint deficiency or paint unevenness at the time of painting, and when used as an outer wall, clear contrast and natural texture that cannot be found in ordinary lightweight cellular concrete panel buildings. was gotten.

In the present invention, the adjacent set only significant difference in height crushing surface together and, by configuring the crushing surface mutual boundary contacting adjacent substantially vertical plane, wide width formed continuously in the boundary of the crushing face each other shadows, it becomes possible to clarify, it is possible to obtain a unique surface texture flooding the emotion more dynamic.
[002 6 ]
In addition, by configuring the substantially vertical surface with a crushing surface, the graininess formed by fine particles on the surface of the crushing surface and the fine shading of the width formed continuously at the boundary between the crushing surfaces described above. It is possible to give it to a wide shadow itself, and it is possible to express a natural texture on the whole, including the boundary part between adjacent crushing surfaces, while it is a unique surface property that is dynamic and full of emotion. Become .
