Description

DETAILED DESCRIPTION OF THE INVENTION a. Industrial Field of the Invention The present invention relates to a mounting means having a locking function and a panel mounting method using the mounting means.

b. Conventional technology and its problems Conventionally, a panel, for example, an ALC panel is fixed to a structural frame by using a bolt 101 and a mounting hardware 102 as shown in FIGS.

Here, the bolt 101 includes a head portion 101a, a shaft portion 101b, and a screw portion 101.
a hexagonal bolt composed of c, passing the bolt 101 through a hole 103 drilled in the mounting hardware 102 and screwing it into an embedding plate 104 embedded in the panel P, thereby connecting the panel P to the structural frame A side. Was fixed to.

However, in the panel mounting method using the bolts 101 described above, when the panel P behaves due to wind pressure, earthquake, or the like, the bolts 101 also rotate, and the screwing between the bolts 101 and the embedding plate 104 is loosened, In some cases, backlash was generated in fixing the panel P.

To prevent this, insert a spring washer 105 for maintaining the contact resistance between the bolt 101 and the mounting hardware 102, or fasten the bolt 101 and the mounting hardware 102 and then fix them by welding. Was being done.

However, even if the spring washer 105 is inserted, loosening can be prevented to some extent, but this is not a fundamental preventive measure, and there is a case where the function does not function at all due to performance deterioration over time.

Further, when the bolt 101 and the mounting bracket 102 are fixed by welding, the rotation of the bolt 101 is completely prevented, and a structure capable of fundamentally preventing loosening is obtained. There is a problem in the workability because it is necessary to take a ground for welding.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the related art, and has as its object to provide a simple structure, which can completely prevent loosening, and has a good workability. Means and a panel mounting method using the mounting means.

c. Means for Solving the Problems In order to solve the above-described problems, the gist of the present invention is to attach an attached member having an anchor provided with a threaded portion on the inner periphery to a threaded portion of the anchor. A shaft having a first threaded portion at one end, a flange provided in the middle of the shaft, a mounting member having a shape into which the flange fits and can prevent rotation thereof, and A second screw portion provided at the end;
Mounting means having a loosening prevention function comprising a nut screwed into the second screw portion and tightening the mounting member to the mounted member; and A panel mounting method characterized in that the panel is embedded in a structural frame, and the panel is embedded in the structural frame.

d. Function The mounting means according to the present invention is characterized in that the shaft body screwed to the anchor provided on the member to be mounted has a flange provided on the shaft body, and a shape in which the flange is fitted to prevent the rotation thereof. Due to the presence of the mounting member having the hole, there is no rotation, and the fixation between the mounted member and the mounting member is not loosened.

In addition, the mounting operation is performed by first screwing a screw portion of the shaft body to an anchor of a member to be mounted, then engaging a hole formed in the mounting member with a flange of the shaft body, Then, the mounting member and the member to be mounted may be tightened, and the workability is good.

e. Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is an exploded perspective view showing the mounting means of the present invention, and FIG. 2 is a side view thereof. 1 in the figure is a screw part at both ends
A shaft body having 2, 3 and a member to be mounted, for example, an ALC panel 5
An anchor plate having a screw portion on the inner periphery fixed by means such as embedding.

The shaft 1 is screwed to the anchor plate 4 via a screw portion 2. Reference numeral 6 denotes a square flange provided in the middle of the shaft 1, and the flange 6 is fixed to the shaft 1 by welding or integral molding.

Reference numeral 7 denotes a mounting member such as a mounting hardware. The mounting member 7 has a flange 6 provided on the shaft 1 as shown in FIG.
Are fitted, and a square hole 8 is formed in which the fitted flange 6 cannot rotate.

9 is a spring washer. Numeral 10 is a nut which is screwed into the screw portion 3 of the shaft 1 and tightens the mounting member 7 to the mounted member 5.

The mounting means configured as described above is assembled in the following order.

First, the anchor plate 4 provided on the attached member 5
Then, the shaft body 1 having the flange 6 is screwed through the screw portion 2.
At this time, the flange 6 is tightened until it comes into contact with the mounted member 5 and the square flange 6 is vertical.

Next, the hole 8 formed in the mounting member 7 is engaged with the flange 6, and the mounting member 7 is set on the mounted member 5.

Thereafter, the mounting member 7 is fixed to the mounted member 5 by tightening the nut 10 via the spring washer 9.

As described above, the mounting means according to the present invention screws the shaft 1 screwed to the mounted member 5 into the hole formed in the mounting member 7 with the flange 6 provided on the shaft 1. As a result, the structure prevents rotation, so once assembled,
The shaft 1 does not rotate, and the fixing between the mounting member 7 and the mounted member 5 does not loosen.

As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention.

For example, in the above embodiment, the flange 6 provided on the shaft 1
Is described as a square shape, but is not limited to this, and various shapes other than a circular shape such as a triangular shape, a hexagonal shape, and an elliptical shape can be used.

However, it goes without saying that the shape of the hole 8 formed in the mounting member 7 should be changed according to the shape of the flange 6 to be used.

f. Effects of the Invention According to the present invention, with a simple structure, loosening can be completely prevented, and the mounting workability has a good locking function, and a panel mounting using the mounting means. A construction method can be provided.
