Description

  The present invention relates to an elevator hall device in which a fire protection partition plate is attached to a three-way frame provided in an opening serving as an entrance / exit for a car in an elevator hall.

The elevator hoistway is formed in the building in the vertical direction, and communicates with the landing on each floor via the opening. This opening is used as an entrance / exit of a car and has a sliding door. In such a building, if a fire occurs on one floor, a shield that automatically closes at the time of the fire is provided at the opening of the landing so that this fire does not spread to other floors through the hoistway. Has been proposed (see, for example, Patent Document 1).
JP 2003-306285 A

  In the above proposal, the opening itself opened and closed by the landing door is shielded to prevent the spread of the fire. In general, a so-called three-way frame that covers three sides of both sides and the upper side forming the inner periphery is attached to the opening. When a three-way frame having a standard shape is used as the three-way frame, a gap is generated between the three-side frame and the opening formed in the building frame. Therefore, in order to close this gap, a fire prevention partition plate is attached.

  This fireproof compartment plate is attached to the opening by conventional welding. However, in order to attach by welding in this way, the construction becomes large and troublesome, such as requiring a welding machine. In addition, since a welding spark is generated, this causes the three-sided frame to be burnt, which causes a design problem. In other words, it looks worse and requires extra work to improve it. In addition, since the thin plates are welded to each other, problems such as difficulty in obtaining the desired strength due to difficulty in action such as opening of holes occur. Furthermore, since it cannot be removed after it has been welded, it may be restricted in the work such as maintenance work, such as the partition plate.

  An object of the present invention is to provide an elevator landing apparatus that can reliably and easily attach a fire prevention partition plate and can obtain an intended fire prevention performance without welding.

An elevator hall device according to the present invention is attached to an opening formed in a building frame that partitions between an elevator hoistway formed vertically in a building and each floor hall, and both sides forming the inner periphery of the opening and An elevator hall device having a three-way frame covering the three sides of the upper side, and provided with a landing door by a sliding door that opens and closes the opening on the hoistway side of the three-way frame, the cross-section of the three-side frame being within the opening An inner peripheral surface portion along the peripheral surface, a front edge portion that covers a space between the inner peripheral surface portion and a landing-side end portion of the inner peripheral surface portion toward the building housing, and the hoistway side end portion of the inner peripheral surface portion And a rear edge portion formed so as to be bent substantially at right angles to the outside of the opening and along the opening / closing direction of the landing door, and at a plurality of locations in the length direction of the rear edge portion, From the edge to the bent part with the inner peripheral surface A pair of cut I, the tongue-shaped portion which forms a part of the rear edge between a pair of cuts are formed, the surface of the tongue-shaped portion, the shaft side of the building structures at its proximal end The fire compartment plate is bent along the tongue-shaped portion of the predetermined angle between the hoistway side surface of the building frame and the anti- landing door side surface of the rear edge portion. The fireproof partition plate and the tongue-like portion are integrally screwed to each other.

  According to the present invention, it is possible to easily and firmly attach a fireproof partition plate by bolting or the like, greatly improve workability, and realize a sufficient fireproof function, and fireproof as an elevator landing device Performance can be increased.

  Hereinafter, an elevator landing apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings.

  First, an embodiment shown in FIGS. 1 to 3 will be described. FIG. 1 is a front view showing the appearance of the elevator hall device in this embodiment. In FIG. 1, reference numeral 11 denotes a rectangular opening, which is formed in a building housing 12 that partitions between an elevator hoistway formed vertically in a building and each floor platform. The opening 11 serves as an entrance to an elevator car that moves up and down in a hoistway (not shown). The opening 11 is provided with a three-way frame 13 and a landing door 14 made of a sliding door.

  The three-way frame 13 covers the three sides of both sides and the upper side that form the inner periphery of the opening 11. The landing door 14 is provided on the rear side of the three-way frame 13, that is, on the hoistway side, and opens and closes the opening 11.

  Further, as shown in FIG. 2, the cross section of the three-way frame 13 includes an inner peripheral surface portion 13a, a front edge portion 13b, and a rear edge portion 13c.

The rear edge portion 13 c is formed so that the hoistway side end portion of the inner peripheral surface portion 13 a is bent at a substantially right angle to the outside of the opening 11 and along the opening / closing direction of the landing door 14.

On the rear edge portion 13c of the three-way frame 13, tongue-like portions 13d are formed at a plurality of locations in the length direction (the vertical direction in the figure) as shown by. The tongue-like portion 13d is formed in a tongue-like shape from the side edge (right side in FIG. 3) of the rear edge portion 13c toward the bent portion (left side in FIG. 3) with the inner peripheral surface portion 13a. The base end portion 13e is bent at a predetermined angle toward the hoistway side surface of the building housing 12 (the lower surface in FIG. 2).

  Reference numeral 15 denotes a fire prevention partition plate provided between the hoistway side surface (the lower surface in FIG. 2) of the building housing 12 and the surface on the counter landing door 14 side (the upper surface in FIG. 2) of the rear edge portion 13c. The fire protection partition plate 15 is attached at a predetermined angle along the tongue-shaped portion 13d, and the fire protection partition plate 15 and the tongue-shaped portion 13d are integrally screwed and fixed with a bolt 16.

  By attaching the fireproof partition plate 15 in this way, the gap formed between the building frame 12 and the three-sided frame 13 is shielded by the fireproof partition plate 15. Therefore, it is possible to effectively prevent a fire that has occurred on a certain floor from expanding from the elevator landing on that floor through the gap between the three-sided frame 13 provided in the opening 11 and the building housing 12. Also, since the fireproof partition plate 15 is attached by screwing with bolts 16 or the like, the work is much easier than in the case of conventional welding, and the design and strength are sufficiently satisfied.
