Description

TECHNICAL FIELD The present invention relates to a decorative panel connecting mechanism for laterally connecting a plurality of decorative panels to cover the outer surface of a pillar such as concrete or the surface of a wall and the like. The present invention relates to a method of connecting decorative panels using a mechanism.

(Prior Art) For example, a large number of pillars whose surfaces are covered with decorative panels can be seen in the platforms of stations, department stores, hotel halls, and the like. As shown in FIG. 3, this pillar is obtained by covering the outer surface of a pillar body 1 made of reinforced concrete with, for example, a stainless steel decorative cover (hereinafter referred to as a decorative panel) 2. , For example, four panels 2a, 2b, 2c, 2d are connected in the lateral direction.

Conventionally, a method as shown in FIG. 5 has been adopted for connecting the decorative panels. Reference numeral 3 is an anchor that is pre-implanted in the column main body 1, and 4 is an angle welded to the anchor 3. A bent portion formed at the end of the decorative panels 2a and 2b is superposed on the angle 4, and is tightened and fixed by a screw 5 of, for example, about 4 mmφ. The method of attaching the decorative panel to the pillar main body or the method of connecting the panels to each other is very easy because they are externally screwed.

However, in the screwed portion, a concave portion having a certain width is formed from the uppermost portion to the lowermost portion of the decorative panel, and the screw head can be seen as it is, which is not preferable in appearance. Therefore, after screwing, the channel 6 is fitted into the recess, or the silicone resin 7 is filled as shown in FIG. 6 to perform a treatment that is not unsightly in appearance. When fitting the channel 6,
It is necessary to bond and fix the side surfaces of the decorative panels 2a and 2b with the adhesive 8. Also, silicone resin 7
At the time of filling, it was necessary to perform processing such as taping so that the resin did not adhere to the surface of the decorative panel, and much labor and time were required for molding the resin surface.

In addition, this screwing method leaves joints of a certain width from the top to the bottom of the decorative panel, which is very noticeable. On the other hand, as shown in FIG. 4, if the adjoining decorative panels 11a and 11b can be brought into close contact with each other, the joints become thin lines, so that they are inconspicuous and can be said to be extremely preferable in appearance.

(Object of the Invention) The present invention solves the above-mentioned drawbacks of the prior art, and as shown in FIG. 4, a decorative panel connecting mechanism capable of adhering adjacent decorative panels and a decorative panel using this mechanism. The purpose of the present invention is to provide a method of connecting the above.

(Structure) In order to achieve the above object, the connection mechanism of the decorative panel of the present invention comprises: a. A first decorative panel having a side surface in which at least one end portion of the left and right ends is bent inward, and an extension portion of the side surface is fixed to a pillar or a wall; b. The side of the first decorative panel. A plurality of shafts are attached at predetermined intervals in the vertical direction, and a shaft having a tapered head like a counterscrew protrudes outward from the side surface, and the decorative panel 1 is provided between the small diameter portion of the taper and the side surface. A fastening member provided with a space corresponding to the plate thickness, c. Of the left and right ends, at least one end adjacent to the side surface of the first decorative panel has a side surface that is bent inward, and a small diameter that is substantially the same as the shaft diameter at a position corresponding to each shaft of the fastening member on that side surface. And a second decorative panel having a hole which becomes a large-diameter portion through which the tapered head portion of the fastening member can easily pass.

According to this configuration, the side surface of the second decorative panel is aligned with the side surface of the first decorative panel, the tapered head portion of the fastening member is introduced from the large diameter portion of the hole, and the second decorative panel is moved downward. By introducing the small diameter part of the hole into the shaft part of the fastening member, both decorative panels can be connected and fixed, both panels are in close contact with each other and the joints are not conspicuous, and installation and removal are also extremely easy Therefore, the cost can be significantly reduced.

(Example) Hereinafter, an example will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which 1 is a pillar main body and 3
Is an anchor implanted in the pillar body 1, and 4 is an angle welded to the anchor 3. W indicates a welded portion. 11
a and 11b are decorative panels of the present invention (hereinafter also simply referred to as panels), and the panel 11a has a side surface whose lateral end portion is bent inward, and is further bent leftward in the drawing from the side surface. The extension is welded to the angle 4. This welding can be easily performed before the adjacent panels 11b are connected. The portion to be welded does not necessarily have to be bent to the left, but may be bent to the right, and may not be bent in relation to the angle weld.

A plurality of fastening members 12 are attached to the side surface of the panel 11a at predetermined intervals in the vertical direction. Here, a bolt having a head portion 12b with a taper 12a is used as a fastening member, and the head portion 12b is projected outward, and the panel 1 is provided between the small diameter portion and the side surface of the taper. The nuts are adjusted and mounted so that a space corresponding to the plate thickness is provided. The fastening member does not necessarily need to use a bolt, and may have a tapered head portion like a counterscrew, and may be fixed so as to project from the side surface with a predetermined dimension. Further, welding may be used as the fixing method. Actually, when performing the construction, a step of attaching the fastening member to the side surface in advance and then fixing the extension portion of the side surface to the column main body is taken.

Similar to the panel 11a, the panel 11b has a side surface whose end portion is bent inward, and the side surface is widened downward as shown in FIG. 2 in correspondence with the position of the fastening member 12. A hole 13 is provided. The upper end of the hole 13 is a fastening member.
At the position corresponding to the 12 shaft (screw part), it has a small diameter part that is almost the same as the shaft diameter, expands downward from there, and the lower end is a large diameter part through which the tapered head 12b of the fastening member can easily pass. Has become.

Therefore, when connecting the panel 11b to the panel 11a, the side surface of the panel 11b is overlapped with the side surface of the panel 11a, and the head 12b of the fastening member is passed through the large diameter portion of the hole 13 as shown by the solid line in FIG. Contact both sides. Next, when the panel 11b is moved downward as shown by the arrow P, the small diameter portion of the hole 13 is guided by the taper 12a of the fastening member so as to engage with the shaft portion as indicated by the broken line in FIG. Become. Since a space corresponding to the thickness of one panel is provided in advance between the side surface of the panel 11a and the small diameter portion of the taper 12a of the fastening member, the panel 11b
The side surface of is fitted in this portion, and is securely fixed with both side surfaces in close contact.

A hole is also formed in the other end of the panel 11b, and the end of the panel 11c adjacent to this has a fastening member similarly to the panel 11a, and if it is fixed to the pillar body, the panel 11b
Both ends of b are held by the panels 11a and 11c, and the mounting of the decorative panel surrounding the column main body 1 is completed. Since a gap of several cm is usually provided between the upper end of the panel and the ceiling and between the lower end and the floor, there is no problem in moving the panel up and down to engage the fastening member and the hole. .
