Description

  The present invention relates to an elevator landing threshold apparatus.

  In a conventional elevator landing sill apparatus, a plurality of mounting members that are substantially L-shaped between a horizontal plane and a vertical plane are arranged at predetermined intervals in the entrance direction of the landing entrance, and each mounting member extends from the top surface of the concrete floor. The anchor is fixed with the vertical surface abutting against the mounting surface of the concrete floor of the landing. Then, the sill member is placed and fixed on the horizontal surface of the plurality of mounting members, is extended in the entrance direction of the landing, the mortar is coated on the upper surface of the concrete floor, and the floor finish is pasted on the upper surface of the mortar. (See, for example, Patent Document 1).

JP-A-5-78073

  In a conventional elevator landing sill apparatus, a gap of about 20 mm to 30 mm is generated between the concrete floor and the sill member, and the mortar falls from the gap. Therefore, prior to mortar coating, on the site, a long steel plate is leaned diagonally between the upper surface of the concrete floor and the landing side wall of the sill member to close the gap between the concrete floor and the sill member. I needed a way to do it.

  Since the landing side surface of the sill member serves as a centering reference surface of each component of the elevator, the landing side surface of the sill member of each landing is located on the same vertical plane. On the other hand, the mounting surface of the concrete floor at each landing is not located on the same vertical plane due to architectural errors. Therefore, the gap between the concrete floor and the sill member varies from one landing to another. In addition, the size of the gap between the concrete floor and the sill member is different on both sides in the entrance direction of the landing entrance. Therefore, the shape of the long steel plate closing the gap is different for each landing, and at each site, the steel plate must be cut according to the gap, and the installation work of the landing sill device is complicated. It was.

  In addition, because the steel plate is diagonally leaned between the top surface of the concrete floor and the landing side wall of the sill member, the gap between the concrete floor and the sill member is plugged, so the mortar near the sill member is coated. The thickness is remarkably thinner than the coating thickness of the mortar on the upper surface of the concrete floor, and there is a problem that sufficient strength cannot be obtained and cracks occur on the finished surface.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an elevator landing sill apparatus that can be easily attached and can suppress the occurrence of cracks in the finished surface of the mortar.

  Each elevator landing sill apparatus according to the present invention has an attachment part and a placement part, and the attachment part is anchored to the wall surface of the hoistway with the sill placement surface of the placement part as the same horizontal plane, A plurality of mounting members installed in the entrance / exit direction, the abutting portion and the concrete receiving portion form a substantially L shape, and the corresponding portion abuts against the wall surface of the hoistway, and the abutting portion of the concrete receiving portion A concrete receiving plate that is placed on the sill placement surface of each of the mounting portions above each of the mounting members, and extends at least over the whole area in the entrance direction of the entrance and exit, and the concrete receiving portion. And a sill member that is fastened and fixed by bolts to the above-described mounting portions of each of the mounting members, and extends in the entrance direction.

According to the present invention, since the gap between the concrete floor and the sill member is closed by the concrete backing plate, the steel plate that plugs the gap that has been conventionally produced for each landing is not required, and the landing sill device can be simplified. Can be attached.
Moreover, when the mortar is coated on the concrete floor, the mortar coating thickness on the landing sill member side can be increased, and sufficient strength can be obtained. Therefore, it is possible to prevent cracks from occurring on the finished surface of the landing floor.

Embodiments of the present application will be described below with reference to the drawings.

  1 to 4, the sill attachment 1 is made of, for example, a steel plate in a substantially L shape having an attachment portion 1a and a support arm 1b, and the support arm 1b is vertical, and the concrete floor 11 is on the hoistway 9 side. The four mounting portions 1a are anchored to the wall surface, and four of them are arranged at predetermined intervals in the frontage direction of the landing entrance 10. The sill bracket 2 is made of, for example, a steel plate in a substantially L shape having a mounting part 2a and a mounting part 2b. The sill mounting surface, which is the upper surface of the mounting part 2b, is set to the same horizontal plane, and the mounting part 2a is formed. The support arm 1 b of each sill mount 1 is fastened and fixed by bolts 12 and nuts 13. Here, the sill attachment 1 and the sill bracket 2 constitute an attachment member. The concrete receiving plate 3 is made of, for example, a steel plate in a substantially L shape having an abutting portion 3a and a concrete receiving portion 3b, and the concrete receiving portion 3b is placed on the sill placing surface of each placing portion 2b. The part 3 a is brought into contact with the wall surface of the concrete floor 11 on the side of the hoistway 9, and is extended in a range exceeding the whole area in the entrance direction of the landing entrance 10.

  The sill member 5 is fastened and fixed to the mounting part 2b of each sill receiving metal fitting 2 by bolts 14 and nuts 15 with a concrete receiving part 3b interposed therebetween, and extends in the direction of the entrance of the landing entrance 10. The three-way frame fixing bracket 6 of the sill member 5 is bolted to the lower end of the three-way frame 17. Further, the ground mortar 7 is coated in a space formed by the wall surface of the concrete floor 11 on the hoistway 9 side, the sill member 5 and the concrete backing plate 3 so as to be in the same plane position as the concrete floor 11. Is coated on the concrete floor 11 and the base mortar 7.

  Here, the sill attachment 1 is adjusted in height so that the upper surface of the sill member 5 protrudes from the upper surface of the concrete floor 11 by the coating thickness of the finishing mortar 8 and is applied to the wall surface on the hoistway 9 side of the concrete floor 11. The anchor is fixed. Further, the notch 4 having such a size that the bolt 14 is loosely formed is formed in the concrete receiving portion 3b so as to correspond to a position where the sill member 5 is fastened and fixed to each sill receiving bracket 2.

According to the first embodiment, since the gap between the concrete floor 11 and the sill member 5 is closed by the concrete receiving plate 3, a steel plate closing the gap that has been conventionally produced for each landing is not required. A landing sill device can be easily attached.
Moreover, when the mortars 7 and 8 are coated on the concrete floor 11, the mortar coating thickness on the side of the sill member 5 can be increased, and sufficient strength can be obtained. Therefore, it is possible to prevent cracks from occurring on the finished surface of the landing floor.
In addition, since the position of the upper surface of the sill member 5 is adjusted so as to protrude from the upper surface of the concrete floor 11 by the coating thickness of the finishing mortar 8, the amount of mortar coating can be reduced and the cost can be reduced.
