DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure in which a thin lightweight cellular concrete wall panel (hereinafter referred to as a thin wall panel) having a surface subjected to a peeling process or the like is attached to a building wall, and in particular, a groove portion. The present invention relates to a wall structure of a natural surface-finished panel formed by mounting or screwing (generally referred to simply as "driving") a fitting into the groove portion of a thin wall panel provided with a groove.

2. Description of the Related Art A conventional ALC panel is a lightweight, ready-made panel reinforced with reinforcing steel bars or the like inside, and has a width of, for example, 6 mm.
It is known as a large panel that is 0 centimeters and several meters long. This ALC panel has the characteristics of being economical, lightweight, fire-resistant and heat-insulating, and excellent in workability. In the construction industry, it is used as a private home, a house with a store, a building roof, a floor, an outer wall, a partition, and the like. It is heavily used.
However, although the ALC panel is a material excellent in such properties, it is generally produced as a panel having a flat flat surface due to production efficiency. Therefore, when used as an outer wall material, there is a problem that the design is poor. is there.

In order to overcome this problem, a method of forming a groove on the surface of an ALC panel has been proposed. For example, JP-A-58-160106 and JP-A-59-167203 disclose a surface enabling technology using a rotary cutting blade. However, those that have been grooved by these technologies, the resulting design is limited to those that are mechanically uniform, and because the shape composed of the surface and the groove is relatively sharp, There is an essential problem that the paint does not easily adhere to the side surface of the groove, and when the side surface is damaged due to an impact during transportation and construction, the damage mark is easily noticeable.

Further, as disclosed in Japanese Patent Application Laid-Open No. 63-25284, there is a technique in which a projection material such as a small steel ball collides against the surface of an ALC panel using an emperor unit to obtain a concave portion, that is, a groove portion. The side surface of the groove becomes steep at an acute angle, damage due to impact during transportation and construction is inevitable, and the damaged part and the surface processed by the small steel ball have different surface textures and the damage mark is easily noticeable. Essential challenges remain.

[0005] Further, as in JP-A-63-82702 and JP-A-63-82705, even when the machining with a small steel ball and the machining of the groove with a blade are used together, the side surface of the groove is steep. It is inevitable that the damaged part is easily damaged by impact during transportation and construction, and the texture of the damaged part is different from that of the other surface.

[0006] In order to fundamentally solve many of the problems described above, the present applicant assigns A
A groove 52 is provided on a part of the surface 51a of the thin wall panel 51 made of an LC panel, and a peeling band 53 is provided on a part of the groove 52 or a part of the surface 51a of the panel following the end of the thin wall panel 51, As a result, there have been invented a number of extremely-designed surface-processed panels capable of displaying the outer surface 51a having a natural stone-like surface texture such as a stone split tone and a stone tone, and have applied for patents for these inventions ( JP 1
No. 1-148198, Japanese Patent Application No. 9-244205,
Japanese Patent Application Nos. Hei 10-347153 and Hei 10-34999
No. 4, etc.)

[0007]

However, the thin wall panel 51 in which a natural stone-like appearance surface 51a such as stone-tone or stone-tone is displayed on the above-mentioned surface constitutes a wall structure having a very high designability. However, when the wall structure is formed by using the thin wall panel 51 having such a natural surface finish, there is a problem as described below.

That is, in the prior art, as shown in FIG. 7, for example, when the aforementioned thin wall panel 51 is attached to a wooden building 54, the width is usually about 600 mm × length about 1800.
A thin wall panel 51 having a thickness of ２０００2000 mm is attached to wall base materials such as pillars 55 and studs 56 of a wooden building 54 at eight to ten places using mounting brackets 57 such as nails, screws and screws as shown in FIG. It was fixed.

[0009] The head 57 of these mounting brackets 57
A repair putty 59 is filled from the surface of the panel into the hole 58 of the portion into which the a has been driven into the thin wall panel 51, and a flattening is performed using a trowel or the like so as to match the uneven texture of the peeling band 53 of the surrounding panel surface 51a. Was composed. After the mounting operation of the thin wall panel 51 is completed, the joints and the like of the thin wall panel 51 are sealed and waterproofed, and then the entire wall is finished with paint.

The surface 51 of the thin wall panel 51 described above
a has unevenness, the panel thickness is different at each location of the thin wall panel 51, and therefore the mounting bracket 5
If the length of the mounting member 7 is constant, the panel thickness is different at each mounting location, so the penetration length of the tip of the mounting member 57 into the wall base material such as the stud 56 for fixing the mounting member 57 is constant. However, there is a problem that the mounting strength varies.

In order to make the length of the mounting bracket 57 penetrating into the wall base material constant, several types of mounting brackets 57 having different lengths are prepared.
7 can be selected and used, but in this case, there is a problem that the operation becomes extremely complicated.

In order to secure the length of the mounting bracket 57 to the wall base material more than a certain length, it is possible to use one type of mounting bracket 57 longer than a predetermined length. When the mounting bracket 57 is driven into the concave portion of the surface 51a of the 51, the length of the mounting bracket 57 driven into the wall base material becomes too long, and also in this case, there is a problem that the construction efficiency is reduced.

Furthermore, as described above, the head 5 of the mounting
The depth of the hole 58 at the portion where 7a is driven into the surface 51a of the thin wall panel 51 is appropriately about 5 mm to 10 mm in order to secure the adhesiveness and durability of the repair putty 59. There is a problem that it is difficult to visually control the depth of the hole 58 at the time of construction because the place where the mounting bracket 57 is driven is entirely uneven.

The wall structure of the surface-finished panel according to the present invention is a completely new technology developed in view of the above-mentioned many problems in the prior art. A completely new technique characterized by forming a groove in the surface of a wall panel and driving a thin wall panel to a wall base material of a building by driving a mounting bracket into the groove to form a wall. It is.

And the adhesiveness and durability of the repair putty filled in the hole formed by the head of the mounting bracket can be ensured.

In addition, in the case where the groove having the inclined surface is formed on both sides of the groove bottom of the groove, it is possible to insert the tool of the mounting bracket even with a narrow groove bottom. .
Moreover, the depth of the groove can be made to appear shallower than the actual depth.

The gist of the third invention of the wall structure of the natural surface finished panel of the present invention is that the groove portion has a groove bottom width of 5 to 20 mm, a groove bottom depth of 3 to 20 mm, and further has a groove bottom. It is a wall structure of the natural surface-finished panel of the first invention or the second invention, wherein the width of the finding on both sides is 1 to 10 mm.

In the third aspect of the present invention, since the groove bottom width and the apparent width of the groove provided on the surface of the thin wall panel are limited to a predetermined range, a mounting bracket is inserted into the groove. It can be driven in a stable state, and it is easy to make the driving depth of the mounting bracket and the depth of the hole formed by the head of the mounting bracket constant. Therefore, the mounting strength of the thin wall panel can be secured, and the adhesiveness and durability of the repair putty can be secured.
