Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint panel used for elevator doors, car walls, basement partitions, etc.

This type of joint panel, especially the joint panel used in elevator cabs, vibrates during operation and may cause discomfort to passengers.In order to prevent this vibration, tar or other material is used as a base material. Apply soundproofing paint to the entire surface of the panel.
I was trying to apply it to a thickness of about 1jl.

However, the workability of applying such a soundproofing paint is poor, and in the case of elevator cabs, etc., there are disadvantages due to increased weight as well as increased manufacturing costs.

In addition, when a box body is constructed from a joint panel made by connecting multiple reference panels, such as in this car room, the vibration mode is such that the entire surface of the joint panel vibrates in a piston-like motion as a unit. 2 vibration components of lO ~ 50Hz and higher mode vibration components of 5011z or higher in the bonded panel.
However, although the soundproofing paints described above are effective in isolating the latter vibration component, they are not nearly as effective in isolating the former vibration component.

Furthermore, since this soundproofing paint hardens after being applied, it has the disadvantage that even the soundproofing effect in the high frequency range is reduced.

This invention aims to improve these conventional drawbacks and provide a bonded panel that can achieve the required vibration absorption effect with a small increase in weight. In a panel, a viscoelastic material lined with a support plate is bonded to the connection part.

Embodiments of the joint panel according to the present invention will be described in detail below with reference to the accompanying drawings.

Figures 1 and 2 show a single panel used in the present invention.The single panel 1 is made of a metal plate casing or a plate-shaped body covered with synthetic resin, etc. The joint parts 1b, 1b are bent, and the joint parts 1b,
1b is further folded inward to form support parts 1c, 1c parallel to the panel part 1a, and the joint parts 1b, 1b
Joint holes 1d, 1d are bored at appropriate intervals in the support portions 1c, 1c, and support bolts 2, 2 are installed in the upper portions of the support portions 1c, 1c.

3 and 4 show a joined panel according to an embodiment of the present invention, in which a plurality of panels 1 are butted together at their joint portions ib and ib, and then tightened with joint bolts 3 and nuts 4. At the same time, a band-shaped vibration absorbing material 5 made of a viscoelastic substance such as rubber is attached to the entire surface of both sides of the adjacent support portions 1c, 1c using the bonding holes ld, ld, and a support plate 6 is attached to the band-shaped vibration absorbing material 5. are bonded to each other with an adhesive, and a nut 7 is screwed onto the support bolt 2 which passes through the band-shaped vibration absorbing material 5 and the support plate 6.

Therefore, in the joint panel according to the embodiment shown in FIG. 3 and FIG.
are superimposed and glued together, so when the joined panels vibrate integrally in a piston motion with this configuration, the fifth
As shown in the figure, the support portion 1c is deformed, and the band-shaped vibration absorbing material 5
Shear deformation occurs between the bonding plate 6 and the support plate 6, and the restoring force provides a vibration damping effect that uniformly acts on the bonded panel surface.

If the adhesion between each of the support parts 1c and 1c and the belt-shaped vibration absorbing material 5 is strong and durable, especially the support bolts 2 and 5 buttons Natsuto 7
Needless to say, there is no need for tightening the vibration absorbing material 5 and the supporting plate 6 for each of the supporting parts 1c and lc. It will be done.

Furthermore, as shown in FIGS. 6 and 7, in addition to the configuration of the embodiment shown in FIGS. By adhering the belt-shaped vibration absorbing material 10 lined with 11, vibration damping is achieved, which damps not only the above-mentioned piston motion-like vibration component of 10 to 50 Hz, but also higher-order modes, that is, vibration components of 50 flz or more. effect can be obtained.

Furthermore, the configuration of the embodiment shown in FIG. 3 and FIG.
As shown in FIG. 9 and FIG. 9, the same effect can be obtained by dividing the band-shaped vibration-absorbing material 5 and the support plate 6 that lines it into individual panels 1. In addition, in this example, each panel Since the band-shaped vibration absorbing material 5 and the support plate 6 can be bonded together in advance when they are joined together, workability can be greatly improved.

Also in each of the different embodiments shown in FIGS. 6 to 9, similar to the embodiments shown in FIGS. 3 and 4,
Of course, tightening with two bolts and nuts 7, formation of multiple layers of belt-shaped vibration absorbing material five buttons and support plate 6, etc. can be applied.

As described in detail above, according to the present invention, a plurality of single panels each having a joint portion on both sides bent at right angles and a supporting portion formed by folding this joint portion inward are connected between each joint portion. In addition, since the bonded panel is constructed by bonding a belt-shaped vibration absorbing material made of a viscoelastic material backed by a support plate to each support part, the belt-shaped vibration absorbing material undergoes shearing deformation due to vibrations applied to the panel part. Due to the restoring force, an effective vibration damping effect can be obtained.

Furthermore, vibration isolation using these band-shaped vibration absorbing materials and support plates does not increase the weight of the bonded panels, unlike the conventional method of applying vibration damping material to the entire surface, reduces work time, and prevents deterioration over time. It has the following characteristics:
