US 2014/0231183 A1 · ELEVATOR CAR

Abstract

The invention relates to an elevator car comprising a support frame, a floor structure and a ceiling structure, as well as at least one car door, and side walls extending between the floor structure and the ceiling structure, wherein the side walls are formed from several wall elements, which are aligned end-to-end or end-to side in corners, wherein the wall elements are composite panels consisting of at least one support material and at least one noise insulating material, that the elevator car comprises at least one flatbar, extending over the surface of both adjacent wall elements, and covering the joint between them, which flatbar comprises or is connectable with fixing elements to at least one of both adjacent wall elements. Via this means the joint between two noise insulating wall elements does prevent any essential noise leakage.

Elevator car comprising a support frame, a floor structure and a ceiling structure, as well as at least one car door, and side walls extending between the floor structure and the ceiling structure, wherein the side walls are formed from several wall elements, which are aligned end-to-end or end-to side in corners, wherein the wall elements are composite panels consisting of at least one support material and at least one noise insulating material, that the elevator car comprises at least one flatbar, extending over the surface of both adjacent wall elements, and covering the joint between them, which flatbar comprises or is connectable with fixing elements to at least one of both adjacent wall elements.

Method of building up an elevator car consisting of a support frame, a floor structure and a ceiling structure, as well as at least one car door and side walls extending between the floor structure and the ceiling structure, wherein the side walls are formed from several wall elements, which are aligned end-to-end or end-to side in corners, wherein flatbars are used for the connection between two adjacent wall elements, which flatbars comprise perforations to be penetrated by bolts, which are fixed to the wall element(s), wherein the perforations in the flatbar comprise first perforations extending over the first of both wall elements and second perforations extending over the second of both wall elements, which longholes of the first and second perforations are tilted towards each other,

in which method a succession of following steps is carried out for the building up of the side walls:
both adjacent walls elements are located end-to end or end-to-side in a corner of two perpendicular extending side walls,
two bolts are fixed to the wall elements into a first fixing position, wherein the bolts are not driven into the wall elements as far as they go to allow the flatbar to be movable with respect to the bolts, whereby the first of both bolts is fixed to the first of the adjacent wall elements and the second of both bolts is fixed to the second of the adjacent wall elements, which two bolts are fixed in a distance which corresponds to the pattern of perforations arranged in the flatbar, whereby,
previously to, during or after the above step the flatbar is put to its mounting location,
the flatbar is moved relative to the bolts in vertical direction, by which movement the adjacent wall elements are caused by the force of the longholes on the bolts to be pressed together,
in a vertical position of the flatbar wherein the pressure force on the wall elements is as desired, the bolts are fixed in a second fixing position in which the flatbar is pressed tightly between the wall elements and the bolt heads.
