BACKGROUND OF THE INVENTION The present invention relates to a steam-cured lightweight cellular concrete panel (hereinafter referred to as ALC) used for an outer wall of a building.
Version).

[0002]

2. Description of the Related Art Conventionally, when the above ALC plate is used for an outer wall of a building, a standard product having a thickness of 10 cm or more has a small hole on the surface at the construction site according to the frame structure of the building. Drilled holes, embedded bolts and nuts, and attached to beams and ruler angles using mounting brackets. However, in this method, not only is it troublesome to repair the bolts and nuts after they are embedded, but there are problems that cracks may occur from the repaired portion and that rain may leak.

As a countermeasure, there is a method in which a nut is fixed and embedded in a reinforcing bar in advance when an ALC plate is manufactured in a factory or the like. However, since the location where the nut is buried cannot be seen from the outside, a large hole must be drilled from the back side to find it, and not only is it troublesome for the work and repair work, but also the frame structure at the site is displaced. In such a case, there was a problem that it took a lot of time to repair and install it.

Further, in the case of a thin ALC plate having a thickness of about 5 cm, the outer surface is screwed to the skeleton such as a stud or a furring strip with a tapping screw, and then a mortar mark on the outer surface is repaired with a special mortar or the like. However, since its thickness is thin, there is a problem that peeling or cracking occurs due to vibration or impact during construction, which easily causes water infiltration. In the case of the thin ALC plate as described above, it is difficult to embed the nut during manufacturing because the size of the reinforcing bar and the surface is small, so it is applied from the outside, so it is pre-painted at the factory or metal plate or Those with tiles attached could not be used.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above problems, and enables the ALC plate to be attached to the skeleton from the back side, and there is no through hole such as a bolt, and the hole is repaired. The purpose is to provide an ALC version that does not require.

[0006]

In order to achieve the above object, the ALC plate according to the present invention has the following constitution. That is, the reinforcing strips embedded in the ALC plate are embedded with the strip strips for attachment to the frame of the building integrally fixed in a substantially parallel to the longitudinal direction or the width direction of the ALC plate. Characterize.

[0007]

When the ALC plate constructed as described above is attached to the skeleton or the like of a building, for example, a side plate of the skeleton or the like is accompanied by an ALC plate, and the skeleton or the like is tapped directly or through a mounting bracket or the like. It can be easily attached with screws. Further, in that case, since the strip plate strip is provided in a direction substantially parallel to the longitudinal direction or the width direction of the ALC plate and has a predetermined width, the mounting position with respect to the frame or the like is in the width direction or the longitudinal direction of the strip plate strip. Even if it is slightly displaced, it can be installed without any problem.

[0008]

The ALC plate according to the present invention will be specifically described below based on the embodiments shown in the drawings. 1 to 4 are partially cutaway perspective views showing an embodiment of an ALC plate according to the present invention. FIG. 1 shows an example in which a strip plate strip 3 is embedded in a relatively thin ALC plate 1 in parallel with its longitudinal direction. In particular, in the case of this figure, three strip plate strips are embedded in the width direction of the ALC plate at substantially equal intervals, and each strip plate strip 3 is integrally welded to the grid-like reinforcing bar 2 by welding or the like. It is fixed. In this example, the outer diameter of the ALC plate has a thickness of 50 mm and a width of 600 mm.
It has a length of 1800 mm. In addition, each strip 3
In this example, an iron steel belt having a width of 75 mm and a thickness of 1.6 mm is used, and its length dimension is substantially equal to the longitudinal dimension of the reinforcing bar 2 and is longer than that of the ALC plate 1. It is formed slightly shorter.

FIG. 2 shows a relatively thin ALC plate 1 similar to that described above.
This shows an example in which the strip plate strips 3 are embedded in parallel with the width direction, and in this example, three strip strips are embedded at substantially equal intervals in the longitudinal direction of the ALC plate. The outer diameter of the ALC plate, the width and thickness of the strip 3 and the material thereof are the same as in the above example, and the length of the strip 3 is the same as the width of the reinforcing bar 2 in the width direction. They are formed to be substantially equal to each other and slightly shorter than the dimension of the ALC plate 1 in the width direction. Other configurations are similar to those in the above example.

FIG. 3 shows an example in which one strip plate strip 3 is embedded in the central portion in the width direction in the ALC plate 1 which is thicker than the above case in parallel with the longitudinal direction thereof. The outer diameter of the ALC plate 1 is
In this example, the standard product is 100mm thick and 600m wide.
It is formed with a length of m and a length of 3000 mm. Strip strip 3
In this example, the width and the material are the same as those in the above example and the thickness is 6 mm, and the other configurations are the same as in the above example.

FIG. 4 shows an example in which strips 3 are embedded in mutually orthogonal pieces of an ALC plate (corner panel) 1 having an L-shaped cross section, one strip parallel to the longitudinal direction of the strip. Regarding the outer diameter of the ALC plate, the thickness of each piece is 50 mm, the width is 100 mm, and the length is 1800 mm in this example. The strip plate strip 3 having substantially the same size as that in the case of FIG. 1 is used, and is integrally fixed to the reinforcing bar 2 having an L-shaped cross section by welding or the like as in the above example.

The outer diameter and shape of the ALC plate are
The present invention is not limited to the above-mentioned embodiment, but may be appropriate. Further, the size, the number, the arrangement position, and the like of the strip plate strip are also appropriate, and may be appropriately selected according to the size of the ALC plate. Further, although the steel strip made of iron was used in the above embodiment as the material of the strips, other strips of metal or other than metal, such as strips of synthetic resin, may be used. It does not have to be altered or deformed, and can be easily attached when it is attached to the frame of a building with a screw or the like, and can maintain sufficient attachment strength.

In order to manufacture the ALC plate in which the strip plate strip is embedded as described above, for example, it may be manufactured in the following manner. That is, a strip plate strip is preliminarily fixed to a desired portion of the reinforcing strip by welding or the like in parallel with the longitudinal direction or the width direction, and the reinforcing strip having the strip strip is fixed by a conventionally known ordinary method. After setting in a frame, the raw material slurry is injected, and when it is solidified into a semi-plastic state, it is cut into a desired size, charged into an autoclave, and steam-cured at high temperature and high pressure.

Next, means for attaching the ALC plate as described above to a building frame or the like is appropriate, but an example thereof will be described. For example, when the ALC plate 1 of FIG. 1 is mounted sideways on a wooden pole or the like, as shown in FIGS. 5 and 6, a hook-shaped metal fitting 12 is provided on a wooden pole 10 which is vertically erected at predetermined intervals. Is attached with a screw 11 or the like, and is screwed to the strip plate strip 3 from the back surface of the ALC plate 1 with a tapping screw 13 or the like, or the metal fitting 12 is first screwed to the strip plate strip 3 from the back surface of the ALC plate 1. The metal fitting 12 may be screwed to the wooden pole 10 in advance. The metal fitting 12 may be L-shaped or U-shaped.

When the ALC plate 1 shown in FIG. 2 is mounted sideways on a wooden pole or the like, it can be mounted in the same manner as described above as shown in FIG. Further, the ALC plates shown in FIGS. 1 and 2 have three strips 3 embedded therein, so that the widthwise central portion of the central strip may be cut along the longitudinal direction as necessary. Two AL
It can also be used as a C plate.

When the ALC plate 1 shown in FIG. 1 is attached to the furring strip in a vertically long shape, for example, as shown in FIGS. 8 and 9, the same metal fitting 12 as described above is used for the tapping screw 1.
3 is screwed to the strip plate strip 3 and the metal fitting 12 is fixed to the iron furring strip 14 or the like by screwing or welding, or the metal fitting 12 is fixed to the furring strip 14 or the like. Can be screwed to the strip plate strip 3 with the tapping screw 13.
When the ALC plate 1 shown in FIG. 2 is mounted vertically, it can be mounted as shown in FIG. 10 in the same manner as described above. As described above, the ALC plates shown in FIGS. 1 and 2 can be easily attached to the frame such as the wooden pole 10 and the furring strip 14 from the back side in either the vertical or horizontal direction.

Next, when the ALC plate 1 shown in FIG. 3 is mounted vertically, for example, a small amount is inserted in the vicinity of the upper end and the lower end of the strip plate strip 3 in the ALC plate 1 from the back surface until the strip plate strip 3 is penetrated. A hole is drilled, and a female screw is cut in the small hole of the strip 3 with a tap or the like. As shown in FIGS. 11 and 12, a metal fitting 17 having a substantially T-shaped cross section is provided on the upper back surface of the lower ALC plate 1 in the drawings.
The lower vertical portion of the screw is directly screwed with a bolt 18. Then, the upper vertical portion of the metal fitting 17 is fixed by welding or the like to the ruler angle 16 integrally fixed to the upper surface of the horizontal beam member 15 as shown in the figure. Next, the lower end of the upper ALC plate 1 is supported by the horizontal portion of the metal fitting 17, and the bolt 20 may be screwed into the hole of the strip 3 so that the ruler angle 16 is sandwiched by the inner metal fitting 19. The strip plate strip 3 is A
Since it is embedded over substantially the entire length of the LC plate 1 in the longitudinal direction, the ALC plate 1 can be cut into a desired length for use.

Further, when the ALC plate (corner panel) of FIG. 4 is attached to a corner of a column or the like, for example, as shown in FIGS. 13 and 14, an L-shaped cross section is formed inside the ALC plate 1 having an L-shaped cross section. The metal fitting 22 is previously screwed to the strip plate strip 3 with the tapping screw 13 or the like, and the ALC plate is arranged at the corner of the pillar 21 and the metal fitting 22 is screwed or welded to the pillar 21 with the tapping screw 23 or the like. Etc. The above-mentioned mounting structure of the ALC plate is an example, and can be appropriately changed according to the purpose of use of the ALC plate, the structure of the skeleton, and the like.

[0019]

As described above in detail, in the ALC plate according to the present invention, the reinforcing bar is provided with the strip plate strip for attachment to the frame or the like of the building, substantially in the longitudinal direction or the width direction of the ALC plate. Since it was embedded in parallel and integrally fixed, the above ALC
When the plate is attached, it can be easily attached to the frame such as the furring strip or stud from the back surface by screwing. Therefore, the drilling work and repair work from the surface are not required, which not only saves the labor, but also can prevent the generation of cracks from the through holes and the intrusion of rainwater. Moreover, since the strength of the ALC plate is greatly improved, the intervals between studs and the like can be increased and the number can be reduced, so that the material and man-hours can be saved. Further, since the construction is performed from the back side, the front side can be painted in advance at a factory or the like, and even an ALC plate to which a metal plate or tile is attached can be attached without damaging the surface,
A very remarkable effect is obtained in practical use.
