Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vibration-proof structure for an aluminum long panel.

[0002]

[Prior Art]

 Conventionally, when a long aluminum panel, so-called spandrel, is installed under a railway station building or under a highway, the vibrations generated by the passage of trains and automobiles will cause the spandrel to come into contact with each other and generate vibration noise. It was a big problem. As a measure for preventing this vibration noise, a device in which a vibration-proof rubber is fitted to the side edge of the panel is often used as shown in FIG.

[0003]

[Problems to be solved by the device]

 However, since these conventional long panels have a structure in which adjacent panels cannot engage with each other when the anti-vibration rubber is removed, the anti-vibration rubber must be worn even when used in places where vibration isolation is not required. However, there was a drawback that the cost was increased accordingly.

The present invention eliminates these drawbacks. When vibration isolation is required, a vibration isolation member can be attached to prevent vibration, and when vibration isolation is not required, it can be attached to the wall surface without the vibration isolation member. The purpose is to create a vibration-proof structure for long panels.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the inventor of the present invention has an anti-vibration structure for a panel, in which a top piece and two side pieces have a substantially U-shaped cross section, and one side piece has an outwardly open engagement piece having a substantially U-shaped section. The insert piece protruding outward is provided on the other side piece, a number of longitudinal grooves are provided on the lower surface of the top piece, and the elastic body is attached to the lower surface of the insert piece, so that the insert pieces are adjacent to each other. When it is inserted into the engaging piece of the panel, the upper surface of the inserting piece is pressed against the upper piece of the engaging piece, and the lower end of the elastic body is elastically deformed and pressed by the lower piece of the engaging piece.

As the elastic body, a mohair-shaped body, a substantially cross-section-shaped elastic body, a hollow half-moon-shaped body, or the like is used.

[0007]

[Action]

 With this configuration, the present invention presses the upper surface of the insertion piece against the upper piece of the engagement piece while elastically deforming and pressing the elastic body against the lower piece of the engagement piece, so that the vibration between adjacent panels is elastic. Since it can be absorbed by the body and the groove is provided on the lower surface of the top piece of the panel, the vibration can be absorbed also by this groove and a sufficient vibration damping effect can be obtained. Moreover, when installing this long panel in a place where vibration isolation is not required, the insertion piece can be fixed while pressing the upper piece of the engagement piece with the panel alone without attaching the elastic body. Further, since the groove is provided on the lower surface of the top piece of the panel to increase the strength, the surface design can be made thinner than the other panels as it is.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In the embodiment shown in FIGS. 1 and 2, the panel 1 is made of a long aluminum mold material having a top piece 2 and two side pieces 3 and 4 having a substantially U-shaped cross section, and one of the side pieces 3 has a crank-shaped end. An engaging piece 5 having a substantially U-shaped cross section that is bent outward is provided, and the tip of the other side piece 4 is bent outward so that an inserting piece 6 is provided. The engaging piece 5 is composed of an upper piece 7, a standing piece 8 and a lower piece 9, and is formed so that the distance from the top piece 2 to the lower surface of the upper piece 7 is slightly larger than the distance to the upper surface of the insert piece 6. There is.

A large number of longitudinal grooves 10 are provided on the lower surface of the top piece 2 at equal intervals, and an upper end of a mohair-shaped elastic body 11 is fixed to the lower surface of the insertion piece 6, and the elastic body 11 has a length. Is formed to be further longer than the length obtained by subtracting the plate thickness of the insertion piece 6 from the length between the upper and lower pieces 7 and 9 of the engagement piece 5.

In order to mount the long panel 1 according to the embodiment of the present invention, first, one long panel 1 is brought into contact with a base material (not shown) attached to the outer wall surface so that the bottom of the engaging piece 5 is removed. After fixing the piece 7 with a screw and fixing it, the next long panel 1 is placed adjacent to the previous long panel 1 and brought into contact with the base material, and the insertion piece 6 is inserted into the engagement piece 5 which is previously fixed. The upper surface of the insertion piece 6 is pressed against the lower surface of the upper piece 7 of the engagement piece 5, and the lower end portion of the elastic body 11 is elastically deformed and pressed against the upper surface of the lower piece 9 of the engagement piece 5.

When the long panels 1 are sequentially mounted adjacent to each other in this manner, the elastic body and the groove 10 absorb vibration noise to form a mounting structure having a sufficient vibration damping effect. Further, when the vibration isolation is not required, the elastic body 11 may not be attached, and the insertion piece 6 and the engaging piece 5 of the adjacent long panel 1 may be sequentially attached to the base material only by press fitting.

The embodiment of FIGS. 3 and 4 shows another embodiment of the present invention. FIG. 3 shows the elastic body 11 having a fixed piece and a free piece in a substantially cross section. 4, the elastic body 11 is a hollow member having a substantially half-moon shape in cross section, and the other structure and operation are the same as those of the above-described embodiment.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, when vibration isolation is required, an elastic body can be attached to provide a mounting structure that absorbs vibration noise and obtains a sufficient vibration isolation effect. If not, there is an effect that it can be attached to the wall surface only with a long panel without attaching an elastic body.Furthermore, by providing a groove on the lower surface of the top piece, the surface design is left as it is and the plate thickness is reduced. Since it has the same strength as other panels, it has various effects such as cost reduction.
