Description

The present invention relates to flat-based lightweight cellular concrete panels, lightweight cellular concrete panel structures and buildings.

Autoclaved lightweight aerated concrete (ALC) panels are widely used for walls, roofs, floors, etc. of buildings as a building material with excellent characteristics such as light weight, heat insulation, noncombustibility, and fire resistance. .

When manufacturing an ALC panel, additives such as aluminum powder are added to the main raw materials such as silica stone and cement and kneaded, and the resulting mixture is poured into a predetermined mold and mixed by chemical reaction. The liquid is foamed and at the same time hardened gradually. Then, when the mixed liquid is in a semi-cured state, it is cut into a predetermined panel shape with a piano wire or the like, and then cured using an autoclave (high-temperature and high-pressure steam cooker) to obtain a completely cured ALC panel (for example, , Patent Document 1).

The panel thus obtained is generally produced as a panel having a flat plane (flat panel) for the convenience of manufacturing.
The features of flat panels are that they provide a calm design that fits in any building shape, that they complement the design of the design panels used as accents, and that other members (entrance doors) work together with openings and exterior wall panels. etc.), it has been popular for a long time.

On the other hand, it has also been attempted to enhance the design of the surface by providing a panel surface with grooves or an uneven pattern (for example, Patent Document 2).

ALC panels generally have scratches such as scratches and dents on the panel surface during (1) the manufacturing process at the factory, (2) the transport process to the site, (3) the construction process at the site, etc. Sometimes.

For example, (1) in the manufacturing process at the factory, when the ALC is in a semi-cured state and the panel is cut with a piano wire or the like to a predetermined thickness, the cut surface (panel surface) may be scratched linearly. There is (2) In the transportation process to the site, multiple ALC panels are piled up to form a block, and multiple blocks are collectively transported to the site. may be scratched. (3) In the construction process at the site, after unloading at the site, the ALC panel is processed into a predetermined shape using an electric tool if necessary, and then screwed, for example, to the outer wall foundation of the building. Fasten using. In this construction process, for example, a panel is scratched by a tool, etc., a safety belt worn by a worker is scratched, and the steel material of temporary scaffolding is scratched. There may be scratches such as dents and scratches.

Such linear scratches are fine scratches with a width of about 0.1 mm to 2 mm, and do not reduce the strength of the panel. However, especially in flat type ALC panels, if a linear abrasion or the like occurs in a predetermined range, the scars are conspicuous even after finishing painting because of the flatness, and even if there is no problem in terms of strength. However, there is a problem that the appearance is deteriorated.

The present invention has been proposed in view of such conventional circumstances, and an object of the present invention is to make linear scratches on the panel surface inconspicuous without impairing the flat design feeling. , a flat lightweight cellular concrete panel, a lightweight cellular concrete panel structure and a building.

Exemplary embodiments of the present invention (hereinafter abbreviated as "present embodiments") will be described in detail below. The present invention is not limited to this embodiment, and various modifications can be made within the scope of the gist thereof. In the specification of the present application, the upper limit and lower limit of each numerical range can be arbitrarily combined.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<Lightweight aerated concrete panel>
(First embodiment)
FIG. 1 is a plan view showing one configuration example of a lightweight cellular concrete panel (hereinafter referred to as an ALC panel) according to this embodiment. Further, FIG. 2 is a plan view schematically showing linear abrasions in the long side direction of the panel (the grooves are omitted in FIG. 2. The same applies to FIGS. 4, 6 and 8 described later. be.).
The ALC panel 1 according to the present embodiment includes a substantially rectangular plate-like panel body 10 made of lightweight cellular concrete. 11. The surface of the panel main body 10 refers to the wide main surface of the plate-shaped panel main body 10 .
In addition, the ALC panel 1 according to the present embodiment is a flat panel, and the term “flat” refers to a substantially flat texture as a whole when viewed from a distance, for example, from a distance of approximately 5 m or more. As will be described later, this means that it is different from a design panel in which relatively large unevenness produces shadows and the pattern can be visually recognized.

Examples of lightweight cellular concrete include ALC described in JISA5416. For example, cement, calcareous raw material, silicic raw material, and water are used as the main raw materials, and a large amount of air bubbles are mixed into the hardened body with a bulk specific gravity of about 0.1 to 1.0, and a reinforcing material embedded inside. Light aerated concrete consisting of

Although the size of the panel body 10 is not particularly limited, as an example, the panel body 10 shown in the drawing has a substantially rectangular plate shape with a long side of 1820 mm, a short side of 606 mm, and a thickness of 37 mm. is formed. However, regarding the outer shape of the panel, an error of about ±2 mm at the time of design and manufacturing shall be allowed.
Reinforcement reinforcing bars, reinforcing nets, etc. (not shown) may be embedded in the panel body 10 to ensure strength.

A plurality of substantially linear grooves 11 are formed on one surface of the panel body 10 substantially parallel to the long sides of the panel body 10 at predetermined intervals.
In this specification, the term "substantially linear" includes not only straight lines drawn with a ruler, but also meandering lines drawn freehand to some extent.

The width (maximum width) of the groove 11 is more than 0 mm and less than 7 mm, preferably more than 0 mm and 4 mm or less, more preferably more than 0 mm and 2 mm or less, 0.3 mm or more and 2 mm. More preferably:
The depth (maximum depth) of the groove 11 is more than 0 mm and less than 4 mm, preferably more than 0.3 mm and less than 4 mm, more preferably 0.3 mm or more and 2 mm or less.

The interval between these grooves 11 is more than 0 mm and 100 mm or less, preferably 10 mm or more and 60 mm or less, and more preferably 10 mm or more and 30 mm or less.

In the present invention, the depth of the groove refers to the dimension of the deepest part, the width of the groove refers to the dimension of the widest part, and the interval of the groove is adjacent from the center of the width of the groove. It refers to the dimension up to the same center part.

By setting the width, depth, and interval of the grooves 11 within the above ranges, even if there is a linear scratch on the surface of the panel, it becomes difficult to visually recognize it after painting is finished. That is, linear scratches on the panel surface can be made inconspicuous. In addition, if the width, depth, and spacing are within this range, the flat design feeling is not impaired.
Note that the plurality of grooves 11 provided in the long side direction may have the same (uniform) width, depth, and spacing, or may have different (random) widths, as long as they are within the ranges described above.

If the width, depth and spacing of the grooves 11 are larger than the above ranges, the effect of making the linear scratches less noticeable after the paint finish cannot be sufficiently obtained. In addition, a flat design feeling cannot be sufficiently obtained. In other words, it looks like a design panel. On the other hand, if the width, depth, and spacing of the grooves 11 are smaller than the above ranges, it becomes difficult (due to errors in panel thickness) to precisely form the grooves 11 on the panel surface during manufacturing.

In particular, in the ALC panel 1 shown in FIG. 1, the plurality of grooves 11 are formed substantially parallel to the long sides of the panel body 10, so that the grooves 11 extend in the long side direction of the panel body 10 as shown in FIG. It is possible to effectively make the linear abrasion 50a along the line inconspicuous.

It should be noted that the angles of these grooves 11 are preferably substantially right angles, not inclined, because the shape resembles the shape of a scratch and the scratch becomes less conspicuous. The angle of the groove means the angle of the side portion of the groove that connects the panel surface and the groove bottom surface.
From a manufacturing point of view, it is possible to provide the side surfaces of the groove 11 with or without an inclination. is preferably provided with a slight inclination from the viewpoint of ensuring a uniform coated surface. From this point of view, it is preferable that the angle of the side portion of the groove 11 is in the range of more than 0 degrees to 75 degrees (the groove width on the panel surface side is wider than the bottom width). The side surfaces of groove 11 may be curved.

Such grooves 11 can be formed in a factory or the like, for example, by cutting with a cutting blade or molding by pressing a molding die while the ALC panel is still soft.

In the ALC panel of the present invention, a linear scratch shape that is likely to occur during panel manufacture, transportation, or construction is patterned, and even if such scratches occur, a similar linear pattern is applied to the panel surface in advance. It is a device that can be visually recognized as a part of the pattern by placing the pattern.

The ALC panel of the present invention is a flat panel, and is different from a so-called design panel (panel with decorative pattern) in which grooves or uneven patterns are provided on the surface of the ALC panel to enhance design. The depth of the grooves or recesses in such a design panel is generally set to a dimension of 4 mm or more, so that the relatively large unevenness creates shadows and makes the pattern visible (see FIG. 10 below). see above).

On the other hand, in the ALC panel of the present invention, shallow linear grooves of less than 4 mm are densely formed (at narrow intervals) so as not to impair the flat-type design like the conventional flat panel. It is a thing. As a result, it is possible to create a natural wall design even when used in combination with a design panel that is used as an accent, for example.

In the case of a completely flat panel, there is a problem that uneven coating tends to occur during coating, but in the ALC panel of the present invention, since the shallow grooves 11 are formed, such uneven coating occurs. There is also the advantage that it is difficult to apply and the finish of the paint is improved.
In addition, in the case of panel construction, in the case of design panels, since the groove depth is large, it is difficult to hold down the spatula after filling the sealing material. Another advantage is that it makes construction easier.

Thus, according to the present invention, even a flat ALC panel with linear scratches on the surface can be used as long as there is no problem in terms of strength, so the panel is discarded. can be reduced, and the loss of resources and the cost of preparing a new panel can be reduced.
