に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a baseboard connection structure of an elevator car. Specifically, a baseboard having a U-shaped cross section is arranged at the lower part of the periphery of the elevator car, excluding the entrance/exit area. The present invention relates to a baseboard connection structure in which baseboards are connected to each other by spot welding at the corner of an elevator car.

。As shown in FIG. 3, in the conventional baseboard connection structure, a double-shaped patch plate 4 is fitted inside one baseboard 2, and the back side of the patch plate 4 is connected to the side plate of the other baseboard 2'. part 2/a, the upper plate part 2b of the baseboard 2 and the upper plate part 4b of the backing plate 4, the f plate part 2C of the baseboard 2 and the lower plate part 4C of the backing plate 4, and the baseboard 2. The side plate part 2'a of ' and the side plate part 4a of the backing plate 4 are each connected by spot welding 5. However, no consideration was given to the fact that a tripping force is applied to the spot weld 5 when the elevator and the floor 3 of the room 1 sag.

炎かシな作業が必要となる。Spot welding is generally used in locations where shearing loads are applied, and when subjected to a load in the peeling direction, the strength is only about 20% of the strength when subjected to a shearing load. In the above-mentioned prior art, when a passenger or baggage gets on the floor 3 of the elevator car 1 and the floor 3 bends, a peeling force acts on the spot welds 5 of the baseboard connection. As mentioned above, spot welds are weak against peeling force, so there is a problem in that the spot welds peel off and a gap is created at the corner of the baseboard. When repairing this gap, spot welding cannot be performed in the building where the elevator is installed, so it is necessary to dismantle the elevator and transport it to a factory for repair, which involves a large flame.

みが働くようにして、点溶接部のはがれを防止できるエ
レベータかご室の巾木結合構造を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a baseboard connection structure for an elevator car that allows only a shear load to act on the spot welds of the baseboard connection, thereby preventing the spot welds from peeling off.

をそれぞれ点溶接によシ結合することで、達成される。The above purpose is to provide baseboards with a U-shaped cross section at the lower part of the periphery of the elevator car, excluding the entrance/exit area, and to join the baseboards together by spot welding at the corners of the elevator car. In the joint structure, an upper plate part and a lower plate part of one baseboard of the corner part are extended, and a U-shaped patch plate is inserted into the lower plate part and the other baseboard,
The extended upper plate and the upper plate of the backing plate, the extended lower plate and the lower plate of the backing plate, the upper plate of the other baseboard and the upper plate of the backing plate, and the lower plate of the baseboard. This is achieved by joining the lower plate portions of the backing plate and the lower plate portions by spot welding.

接部がはがれることが防止される。At the joint part, the extended upper plate part of one baseboard and the upper plate part of the backing plate, the extended lower plate part of the baseboard and the lower plate part of the backing plate, and the upper plate part of the other side and the backing plate. Since the upper plate parts, the lower plate part of the baseboard, and the lower plate parts of the backing plate are each spot welded, one baseboard receives a load in the vertical or horizontal direction relative to the other baseboard. Even in this case, only shear load acts on the spot weld. This prevents the spot welds from peeling off.
