Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for correcting a step between a lightweight cellular concrete panel (hereinafter referred to as an ALC panel) or an extruded panel, and more particularly, to a structure of a wall panel constituted by an ALC panel or an extruded panel. The present invention relates to a structure capable of correcting a generated step difference between panels on a back surface of a wall.

[0002]

2. Description of the Related Art When a wall is formed of an ALC panel or an extruded panel, as shown in FIG. 4, a wall 1a of one long panel 1 and a wall 2a of the other panel 2 abut against each other. In recent years, in order to easily absorb the vibration of the panel due to an earthquake or the like, in recent years, joints generally referred to as joints by working joints capable of following the displacement between buildings as represented by a rocking construction method have been proposed. A wall having a portion 3 (hereinafter referred to as a working joint joint) is often formed.

The above-mentioned working joint joints are filled with a backup material, a sealing material, etc., but no mortar or reinforcing bar is inserted into the joint joints of the ALC panel, that is, the panels are fixed to each other. Since the joint portion is not provided, the joint portion 3 has excellent followability to the displacement between buildings. As a form of the working joint joint, a joint (not shown) in which the panel edge faces are in contact with each other is often used, but expansion and contraction adjustment having a slight gap between the panel edge faces as shown in FIG. Joints are often used.

[0004]

On the other hand, since the ALC panel or the extruded panel is generally narrow and has a longitudinal length of about 3000 mm, the panel 1 is warped (curved) in the longitudinal direction. Occurs. Therefore, when the joint part 3 is a working joint joint part, unlike the insertion muscle construction method,
Since the panels are not fixed to each other at the joint portion, if the degree of warpage between the butted panels is different, a curved portion appears as a step D in the middle portion of the panel as shown in FIG. There was a problem that the appearance of the building was spoiled.

[0005] Such a problem also has a similar problem in a corner portion (not shown) to which an L-shaped corner panel is generally applied, and the L-shaped corner panel is hardly curved and has a low linearity. Since it is easily maintained, a step with the flat panel is more likely to appear. In any case, the joint D is a working joint joint, and the step D is a middle part of the panel. Therefore, conventionally, there is no effective means for correcting the step.

Accordingly, an object of the present invention is to provide a wall having a working joint joint formed of an ALC panel or an extruded panel, and to reduce a step between panels caused by warpage of the panel without impairing the ability to follow the displacement between buildings. ALC that can be corrected and does not impair the appearance of the wall
It is to provide a straightening structure between panels or extruded panels.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a step correcting structure according to the present invention has a joint formed by a working joint by joining small edges of a long ALC panel or an extruded panel. A structure for correcting a step between panels caused by panel warpage of a formed wall, wherein one end of a first fixing member is located at a joint at a vertically intermediate portion of the panel on the back surface of the wall. The first fixing member is fixed to one panel surface, and the second fixing member is arranged such that one end of the second fixing member overlaps with one end of the first fixing member at a predetermined interval. A structure fixed to the other panel surface, wherein one end of the first fixing member and one end of the second fixing member are connected by a screw and the distance therebetween is adjustable. It is.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a first embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the code | symbol same as a conventional example. Figure 1 shows the long ALC panels 1, 2
1 is a schematic cross-sectional view of a case where the present invention is applied to a wall formed by abutting small edge surfaces 1a and 2a. FIG.
, The joint portion 3 has a slight gap and is filled with a backup material 4 and a sealing material 5. That is, it is the working joint joint part of the expansion / contraction joint by the rocking construction method.

On the back surface of the wall as described above, the first fixing member 6 made of a steel plate is positioned with the screw 7 and the adhesive so that one end 6a of the first fixing member 6 is located at the joint 3 at the middle portion in the vertical direction of the panel 1. A fixing member 6 is fixed to the back surface of one panel 1. Also, a second fixing member 8 made of a steel plate is fixed to the back surface of the other panel 2 with a screw 7 and an adhesive, and one end 8 a of the second fixing member 8 is positioned below one end 6 a of the first fixing member 6. It is bent and extended
Further, it overlaps with one end 6a with a predetermined interval.

Further, as shown in FIG.
A long hole 6b is drilled at one end 6a of the
A female screw is threaded at one end 8a of the fixing member 8,
Both ends 6a and 8a are connected by screws 9 via washers. By tightening or loosening the screw 9, the gap between the both ends 6a and 8a is adjusted to correct the panel warpage, thereby correcting the step D.

The female screw for screwing the screw 9 is:
An elongated hole 6b larger than the diameter of the screw 9 as shown in FIG. 2 is drilled in only one end 8a of the second fixing member 8 and threaded in the one end 6a of the first fixing member 6. Is more preferable from the viewpoint of improving the followability to the displacement between buildings,
A round hole larger than the diameter of the screw 9 is also applicable.

In the present invention, the material and shape of the first fixing member 6 and the second fixing member 8 are not particularly limited, but it is desirable that the first fixing member 6 and the second fixing member 8 be made of a steel plate and have a thickness of about 1.0 mm to 6 mm. The fixing to the panel is preferably performed by using a screw and an adhesive as in the embodiment, in terms of fixing strength, but the fixing strength can be maintained only with the screw or the adhesive alone.

It is desirable that the diameter and length of the screw be appropriately selected according to the thickness of the panel.
When the diameter is from 4 to 150 mm, a diameter of from 4 mm to 8 mm and a length of from 50 mm to 90 mm are preferable because sufficient fixing strength can be obtained. As the adhesive, a fast-curing elastic adhesive such as “SG-1” (manufactured by Cemedine Co., Ltd.) is suitable.

Although the above embodiment has been described with reference to an ALC panel, the present invention is also applicable to an extruded panel. As the wall structure, in addition to the flat wall structure in which the panels 1 and 2 are butted as in the embodiment, a corner portion (not shown) of a structure in which flat panels are butted on both sides of an L-shaped corner panel. Can also be applied. Further, although the present invention has a remarkable effect on the correction of the warpage of the panel, it can be applied to a normal connection structure of the panel as required.

[0015]

According to the present invention, a panel formed by warpage of a panel on a wall formed to have a joint by a working joint by abutting small edges of a long ALC panel or an extruded panel. It is possible to easily correct the step only by adjusting the distance between the fixing members fixed to the panel surface with a screw, so that the correcting operation is easy, the structure is simple, and the cost is low.

Further, since the fixing member is fixed to the back surface of the wall, the correction can be performed on the back surface of the wall, which does not adversely affect the painted surface and the appearance of the panel surface and seals the joint. Applicable later. Furthermore, since a thin steel plate of 6 mm or less can be used as the fixing member, there is almost no hindrance to the interior. And since the straightened panel does not return to its original shape, the appearance of the wall is not permanently damaged. Further, if a long hole larger than the diameter of the screw is perforated at one end of the fixing member, the ability to follow the shaking at the time of the earthquake, that is, the displacement between the building layers is improved.
