DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an ALC panel for a floor or a roof, which is mounted on an upper flange portion of an H-shaped steel beam of a building driving body via a mounting bracket.

[0002]

2. Description of the Related Art ALC panels for floors or roofs (hereinafter referred to as ALC panels)
It is called a panel. Japanese Patent Application Laid-Open No. 7-286392 and Japanese Patent Application Laid-Open No. 9-28772.
The structure and method disclosed in Japanese Patent Publication No. 29 have been proposed. That is, in the mounting structure disclosed in Japanese Patent Application Laid-Open No. 7-286392, as shown in FIGS. 6 and 7, the mounting bracket 20 is formed by bending the H-shaped steel beam 6 by bending portions 20b provided at both ends thereof.
Of the adjacent panel 1 by holding the upper flange 6a of
It is located at a position straddling the joint. And the mounting bracket 20
The panel 1 is placed on the flat part 20 of the mounting bracket 20 through the embedded washer 21 from the front side of the panel 1.
It is driven into a.

As shown in FIGS. 8, 9 and 10, a narrow fitting portion 22b of a mounting bracket 22 is fixed to an upper flange portion 6a of an H-shaped steel beam 6, and the flat plate portion 22a is attached to the panel 1 as shown in FIG. The panel 1 is placed on the H-shaped steel beam 6 so as to be housed in the cut portion 3 provided on the back side of the panel. The tip 2 of the mounting bracket 22 protruding from the end of the panel 1
With the mark 2c as a mark, the screw 2 is driven into the flat plate portion 20a of the mounting bracket 22 from the front side of the panel 1.

[0004]

However, in the case of the mounting bracket 20 shown in FIG. 6, when the screw 2 is driven into the flat plate portions 20a and 22a of the mounting brackets 20 and 22 from the panel 1 surface side, the position is difficult to understand. The mounting bracket 22 shown in FIG.
In the case of (1), the distance to drive the screw 2 from the end of the panel 1 was difficult to understand.

[0005] For this reason, in the construction site, a blackout operation for determining a position for driving the screw 2 is usually performed. However, the inking work is very time-consuming and may be inaccurate even if the inking is performed.
When the accuracy of the driving operation of the screws varies, the positions of the screws 2 become irregular, and the finish is often poor. Also, if the screwing operation is omitted and the screwing operation is omitted, the screwing of the screw 2 may be forgotten, or the screw 2 may come off from the flat plate portion 5a of the mounting bracket 5 and penetrate the panel 1, or the H There was a problem that the screw 2 hit the upper flange portion 6a of the shaped steel beam 6 and the panel 1 was not fixed.

Further, since the length of the screw 2 is required to be equal to or more than the thickness of the panel 1 and is generally as long as 100 mm or more, it is difficult to accurately drive the screw 2 perpendicularly to the surface of the panel 1. In many cases, the screw 2 does not strike the flat plates 20a and 22a vertically. As a result, it was sometimes impossible to pierce the flat plates 20a and 22a. In particular, in the mounting bracket 22 shown in FIG. 9, the closer the screw 2 is driven to the end (the right side in the figure) of the flat plate portion 22a, the more the flat plate portion 22a bends, and the tip of the screw 2 slips and cannot be drilled. there were. Also, as a mark, the mounting bracket 2
Since the second tip 22c protrudes from the end of the panel 1, the joints between the adjacent panels 1 are unnecessarily wide, and a large amount of filler is required.

When the screw 2 pierces the inside of the thick panel 1, the cutting edge of the screw 2 is already worn before reaching the mounting brackets 20, 22.
Also, there has been a problem that the holes 22a and 22a cannot be pierced. In addition, the shavings of the panel drilled by the screwing operation of the screw 2 at the site fall on the lower floor and enter the eyes of the person, and the ALC powder adheres to the metal members such as the sash, and the safety surface and There were also quality issues.

Accordingly, an object of the present invention is to solve the above-mentioned problems, eliminate the need for inking on site, and accurately or surely facilitate the driving of screws from the panel surface. ALC for efficient floor or roof
An object of the present invention is to provide a panel mounting structure.

[0009]

According to the present invention, there is provided an ALC for a floor or a roof, which is attached to an upper flange portion of an H-shaped steel beam of a building vehicle via a mounting bracket.
In the panel mounting structure, the ALC panel has a notch portion for a mounting bracket on the back surface thereof and a hole for a mounting screw having a diameter of 2 to 8 mm on the panel surface side corresponding to the position of the notch portion in the ALC panel manufacturing plant. The mounting bracket is formed from a flat plate portion and a fitting portion fitted to an upper flange portion of the H-shaped steel beam, and the mounting bracket is provided with the fitting bracket. A floor or roof ALC panel mounting structure in which screws are driven into the flat plate portion from the mounting screw holes on the panel surface side is employed. Here, the inside of the panel manufacturing plant means the range before the panel is shipped to the panel installation site.

The operation of the present invention will be described below. If a notch for a mounting bracket is previously provided in the panel manufacturing factory on the back surface of the panel, the panel mounting bracket attached to the upper flange portion of the H-shaped steel beam of the building vehicle can be fitted into this notch. Therefore, the panel can be stably mounted at a predetermined position.

In addition, if a mounting screw hole having a diameter of 2 to 8 mm is provided in a panel manufacturing factory in advance on the surface corresponding to the position of the cutout, blacking is performed at the time of mounting the floor or roof panel at the construction site. Is no longer needed. Further, since the mounting screw holes are preliminarily formed, the positions of the screws are not uneven when the screws are driven into the panel, and the screws can be accurately and vertically driven into the flat plate portions of the panel and the mounting bracket. . In addition, there is almost no powder dropping due to the perforation of the panel, and the cutting edge of the screw is not worn, so that it is not difficult to perforate the mounting bracket.

If the mounting screw hole is a small hole having a diameter of 2 to 8 mm, the diameter of the mounting screw can be set slightly larger than this, so that the screwing with the panel can be sufficiently maintained and the screw is driven. There is no need to repair the panel surface later.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A description will be given based on FIG. In addition, the same code | symbol was attached | subjected to the code | symbol same as a prior art example. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a perspective view of a panel 1 used for the embodiment. 1 and 2, the panel 1 is provided with a U-shaped cut portion 3 on the back surface thereof, in which a mounting bracket 5 is fitted.
A hole 4 for a mounting screw having a diameter of 4 mm is provided in the panel manufacturing factory in advance on the panel surface side corresponding to the position.

As shown in FIG. 1, the panel 1 is attached to an upper flange portion 6a of an H-shaped steel beam 6 of a building body via an attachment fitting 5. As shown in FIG. 3, the mounting bracket 5 includes a flat plate portion 5 a and a fitting portion 6 c fitted to the upper flange portion 6 a of the H-shaped steel beam 6, and is mounted on the cut portion 3 of the panel 1. The panel 1 is laid on the upper surface of the upper flange portion 6a of the H-shaped steel beam 6 with the flat plate portion 5a of the metal fitting 5 fitted therein. The screw 2 is driven into the flat plate portion 5a from the mounting screw hole 4 on the surface of the panel 1.

As shown in FIG. 3, the mounting member 5 is a U-shaped body having a cross section with a side plate 5b provided at right angles to both ends of a flat plate 5a, and is fitted to the side plate 5b along its lateral direction. A mating groove (fitting portion) 5c is formed. Since the width of the fitting groove 5c is slightly smaller than the thickness of the upper flange portion 6a of the H-shaped steel beam 6, the fitting groove 5c can be fitted and attached to the upper flange portion 6a by friction. Further, unlike the conventional mounting bracket 22 having a simple plate structure shown in FIG. 8, since the upper and lower portions of the fitting groove 5c are formed by the side plates formed in the vertical direction, the fitting groove 5c can easily spread. Thus, the fitting force is not weakened, and the mounting strength of the mounting bracket 5 and the panel 1 is increased.

The cutout 3 of the panel 1 is not limited to a U-shape, and various shapes such as a circle, an ellipse, a square, and a polygon can be applied as long as the fitting for mounting the panel 1 can be fitted. You. It is more preferable that the mounting screw hole 4 penetrates from the surface of the panel 1 to the cut portion 3 because it is not necessary to pierce the base material of the panel 1 with the screw 2 and powder fall is reduced. In the present invention, the diameter is in the range of 2 to 8 mm, but in the range of 4 to 5 mm,
The use of the screw 2 having a diameter of 5.2 to 5.7 mm is more preferable because the panel 1 can be sufficiently screwed together and the mounting strength of the panel 1 to the H-shaped steel beam 6 can be sufficiently ensured.

As shown in FIG. 2, if one notch 3 is provided at the center of the panel 1 in the width direction,
The panel 1 can be stably fixed to the upper flange portion 6a of the H-shaped steel beam 6 with a small number of mounting brackets 5 without rattling.

The diameter of the screw 2 is larger than the diameter of the mounting screw hole 4 by 0.
When it is larger by about 5 mm, it becomes easy to bite into the base material of the panel 1. Further, if the screw 2 is provided with a washer, the bearing area of the panel base material is increased, and the panel 1 can be fixed more firmly. Further, holes 4 for mounting screws on the panel 1 are provided.
From the end of the upper flange portion 6a of the H-shaped steel beam 6
When set at a position 20 mm apart, the flat plate 4
The tip of the screw 2 does not slip due to the bending of the screw a, and the screw 2 can be driven perpendicular to the flat plate portion 5a.

Further, the finish after construction is improved by this mounting structure, and the construction efficiency can be improved. For example, as shown in FIG.
If the mounting screw hole 4 is provided at the center position in the width direction of
The screw 2 is arranged at a position aligned with the adjacent panel 1, and the screw 2 can be reliably driven into a center position in the width direction of the flat plate portion 5 a of the mounting bracket 5. Further, if similar notches 3 and mounting screw holes 4 are provided at both ends of the long side of the panel 1, mounting workability is further improved, which is more desirable.

[0020]

According to the present invention, the following effects can be obtained. At the construction site, the blackout work of screw driving positioning is not required, and the work efficiency of screw driving is improved. The ALC panel for floors or roofs having a good finish with the screws aligned can be constructed, and the panel can be stably and reliably mounted at a predetermined position. Furthermore, the problem of powder dropping due to the drilling work at the construction site is reduced, and problems such as safety and quality in which ALC powder adheres to metal members are solved. In particular, according to the fourth aspect of the present invention, it is not necessary to perform blackout at the site, the driving of the screw is facilitated, and the panel can be stably mounted on the H-shaped steel beam without rattling.
