Description

Detailed Description of the Invention

[0001]

The present invention relates to a hollow extrusion molded plate, ALC
The present invention relates to a structure for attaching a panel such as a plate or a cement-based panel to a frame, and more particularly to a locking attachment structure for a panel in which a fastening portion for fastening the panel is prevented from loosening.

[0002]

2. Description of the Related Art Among conventional structures for attaching a panel to a frame, an example of a structure for attaching a hollow extruded plate to the frame will be described below. That is, FIG. 5 (A),
In (B), when attaching the hollow extruded molded plate 1 to the ruler angle 2 on the frame side, a flat steel plate mounting plate (fastener) having screw holes 3a in the hollow portion 1a of the hollow extruded molded plate 1 3, and the spring washer 4, the washer 5, the long hole 6a of the Z-shaped metal 6 and the bolt 7 inserted through the bolt hole of the hollow extruded plate 1 are screwed into the screw hole 3a of the fastener 3. The hollow extruded plate 1 was attached to the body by tightening by tightening.

By the way, in the above-mentioned mounting structure shown in FIGS. 5A and 5B, the spring washer 4 is used to prevent loosening, but the complete integration of the bolt 7 and the fastener 3 cannot be obtained. ,
Once the relationship between the two began to loosen, there was a problem that the effect of the spring washer 4 was not obtained and the loosening continued to progress.

In order to improve the above-mentioned conventional problems, for example, a technique according to US Pat. No. 3,642,937 (first known technique) or a technique according to Japanese Utility Model Publication No. 54-45504 (second known technique) is adopted. A method of fastening the panels using the method is also practiced.

The first known technique has a structure in which an epoxy resin is encapsulated, and the capsule is attached to the outer peripheral surface of the bolt with an amine-containing adhesive. In the case of this technique, when a nut is attached to the bolt, the capsule is broken and the adhesive force of the epoxy resin inside the capsule is exerted so that the nut screwed into the bolt is not tightened. Further, the second known technology is that when a synthetic resin elastic body having elasticity and a restoring force and having a kamaboko type length is press-fitted into a screw thread of a bolt and fixed, and the bolt is screwed, the outer peripheral surface of the bolt is The loosening of the bolt is prevented by the friction between the outer surface of the elastic body and the outer surface of the synthetic resin elastic body.

There is also an example of using an insect pin which is generally known as the third known technique. In the case of the insect pin, initial loosening occurs, but when the nut rotates to the position of the insect pin, the effect of the insect pin prevents the loosening from further progressing. In this case, as shown in FIG.
A hole 7a penetrating the diameter is provided in the bolt 7 in advance, and after the hollow extruded plate 1 is attached by the bolt 7 and the fastener 3, the insect pin 8 is inserted from the hollow portion 1a of the hollow extruded plate 1. Then, the bolt 7 is configured to be inserted into the hole 7a provided in the bolt 7.

[0007]

However, when the panel is mounted and fixed to the body side using the bolts according to the above-mentioned first known technique, the purpose of preventing the fastener from loosening can be achieved to some extent. However, there is a problem that once the fastening portion starts to loosen due to vibration or wind pressure for a long period of time, it cannot be stopped. Further, when the panel is mounted and fixed to the body side by using the bolts having the second known technique, it is necessary to have extremely high precision when mounting and fixing the panel, and the fastener is attached to the synthetic resin. If the elastic body was not covered, there was a problem that the loosening prevention function could not be exerted. Further, in this case as well, once the fastening portion begins to loosen due to vibration or wind pressure, even if the synthetic resin elastic body is restored, it does not function as a stopper because it is inclined near the nut position, so it can be stopped. There was a problem I could not do.

In the case of the third known technique, after the hollow extruded plate 1 is attached by the bolt 7 and the fastener 3, the insect pin 8 is inserted from the hollow portion 1a of the hollow extruded plate 1. Although it must be done, in the state where the hollow extruded plate 1 is already attached, the self-weight receiving member (not shown) that supports the self-weight of the hollow extruded plate 1 blocks the hollow portion 1a, so Insect pin 8 into bolt 7 hole 7a
There was a problem that it was difficult to insert into.

The panel anti-loosening mounting structure according to the present invention is a completely new technology developed in view of the above-mentioned conventional problems, and particularly in the structure for mounting the panel on the body, the structure is attached to the tip side of the bolt. A resin elastic body is embedded, and a fastener screwed to the bolt is arranged so as to be located on the head side of the synthetic resin elastic body, whereby loosening of the fastening portion to which the panel is attached can be prevented. It provides technology.

[0010]

The loosening prevention mounting structure for a panel according to the present invention is a technique which has fundamentally improved the above-mentioned conventional problems. The gist of the first invention is a bolt and the bolt. In a structure for attaching a panel to a body using a fastener having a screw hole that can be screwed into, a synthetic resin elastic body is embedded in the tip side of the bolt, and the fastening screwed into the bolt is further performed. A panel locking structure is characterized in that the tool is located closer to the head of the bolt than the synthetic resin elastic body embedded in the bolt, and the panel is mounted to the body.

A second aspect of the present invention is a structure for attaching a panel to a frame using a bolt and a fastener having a screw hole that can be screwed into the bolt, wherein the screw portion of the bolt or the fastener is attached. An adhesive is applied to the screw holes, and a synthetic resin elastic body is embedded on the tip side of the bolt, and the fastener screwed into the bolt is further tightened from the synthetic resin elastic body embedded in the bolt. Is a panel locking structure, characterized in that the panel is located on the head side and is attached to the body.

[0012]

[Operation] First of the panel locking structure according to the present invention
In the invention, as described above, the synthetic resin elastic body is embedded in the tip end side of the bolt having the panel attached to the body, and the fastener screwed to the bolt is headed from the synthetic resin elastic body. Since it is located on the side, even if the fastener loosens and tries to move along the bolt, this synthetic resin elastic body acts as a stopper, which prevents the fastener from loosening.

In the second invention of the panel loosening attachment structure according to the present invention, as described above, the adhesive is applied to the screw portion of the bolt for attaching the panel to the body or the screw hole of the fastener. Therefore, the adhesive intervenes between the fastener and the fastener screwed to the threaded portion to exert an adhesive force, and thus the fastener can be prevented from loosening. Further, since the synthetic resin elastic body is embedded in the tip end side of the bolt and the fastener screwed to the bolt is located on the head side of the synthetic resin elastic body, the fastener is loosened. The synthetic resin elastic body acts as a stopper even when the fastener is trying to move along the bolt, which prevents the fastener from loosening. Therefore, in the case of the second aspect of the invention, it is possible to prevent the mounting and fastening portion of the panel from loosening in two steps.
