FIG. 3 is a horizontal sectional view of the elevator panel shown in FIG. The elevator panel according to the first embodiment includes a front plate 31, a flat back plate 32 facing the back surface of the front plate 31 and facing the hoistway 1, and a back surface of the front plate 31. It is a double structure panel having the vertical reinforcing member 33 fixed.

The front plate is made of a steel plate such as a stainless steel plate (SUS), a cold rolled steel plate (SPCC), or an electrogalvanized steel plate (SECC). The back plate 32 is composed of a composite steel plate. The longitudinal reinforcing member 33 is made of a steel plate such as a cold rolled steel plate or an electrogalvanized steel plate.

The front plate 31 includes a flat front plate main portion 31a and a pair of bent portions formed by bending both ends of the front plate main portion 31a in the width direction (left and right direction in FIG. 3) to the back plate 32 side. 31b and the edge part on the opposite side to the front-plate main part 31a of the bending part 31b are bend | folded at right angle, and it has a pair of opposing part 31c which opposes the back surface of the front-plate main part 31a. That is, both end portions in the width direction of the front plate 31 are bent into a U-shaped cross section.

Both end portions in the width direction of the back plate 32 are overlapped with the surface of the facing portion 31c opposite to the surface facing the front plate main portion 31a, and are mechanically fixed to the facing portion 31c. The mechanical fixing is fixing using a plurality of fasteners (for example, rivets or screws) or fixing by welding.

The horizontal cross-sectional shape of the vertical reinforcing member 33 is opposite to the straight bottom surface portion 33a, the pair of joint portions 33b projecting perpendicularly from both ends of the bottom surface portion 33a in the same direction, and the bottom surface portion 33a of the joint portion 33b. It is a hat shape which has a pair of leg part 33c which protruded from the edge part of the side at right angles outward.

However, since the back plate 32 is composed of a composite steel plate, vibration of the back plate 32 is suppressed by the buffering effect of the adhesive layer 42, and noise can be reduced. For this reason, a certain level of noise reduction can be achieved with a simple structure without filling the panel with a sound absorbing material such as glass wool.

Further, the rear plate 32 of the car door panel 12 and the

wall panels

21, 22, and 23 is made of a composite steel plate, so that the noise in the car room 11 can be reduced.
Furthermore, the noise of the hall can be reduced by configuring the back plate 32 of the hall door panel 13 with a composite steel plate.

Furthermore, the weight can be reduced as compared with the case where the sound absorbing material is filled.
Moreover, since the operation | work which fixes a sound-absorbing material to the front board 31 or the back board 32 is unnecessary, workability can be improved and cost can be reduced.
