Abstract

PURPOSE:To efficiently perform design, manufacture, and assembling work of a landing device for an elevator without being influenced from story height of a building, by connecting together vertical members and a hanger case through a plurality of brackets, and dispersing hanger case supporting function to supporting pillars and vertical members so as to support load. CONSTITUTION:For supporting load on a hanger case 6, a part of steelwork on the building side, vertical members 3a, 3b and guide rails 12a, 12b are connected together through brackets 9 so as to bear load in the horizontal direction, and supporting pillars 8a, 8b of the hanger case 6 are burdened with load in the vertical direction. Hereby, even if the story height of the building is high, rigidity of the vertical members can be compensated, and the horizontal force from the outside generated through a landing door and the horizontal force generated by earthquake and the like can be supported. Meanwhile, the supporting pillars are burdened with load in the vertical direction on the landing door, the hanger case, and the like. Thus, because it is unnecessary to change the length of the supporting pillar each time, efficiency of design and manufacture are improved, and respective mistakes can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator hall device in a steel building.

[0002]

2. Description of the Related Art In a conventional device, as described in Japanese Patent Laid-Open No. 51-69853, the support pillars at both ends of the hanger case are extended to near the floor cross members on the upper floor, and the upper ends of the support pillars are provided with connecting fittings. It was connected to the building steel frame through.

[0003]

The prior art has been a bottleneck in standardization in design and manufacturing because the floor height of the building differs depending on the building or the floor of the same building. In addition, it was necessary to design the steel structure of the building after grasping it securely, and it was not possible to flexibly respond to changes in the building, and it was necessary to change the material size according to the floor height, which was extremely troublesome. .. As for local assembly workability, it was necessary to select a product suitable for the floor height, and depending on the floor height, it was necessary to take a special transportation method as a heavy load.

The object of the present invention is not affected by the floor height of the building,
It is to provide a landing gear device that enables efficient design, production, and assembly work.

[0005]

To achieve the above object, the rigidity of the vertical members on both sides of the building opening is utilized to connect the vertical members and the hanger case through a plurality of brackets. That is, the hanger case supporting function was provided only to the supporting columns, but the supporting columns and the vertical members were dispersed and supported. Further, the horizontal bracket is extended so that the support bracket is projected from the end portion and connected to the guide rail to increase the rigidity of the vertical members on both sides of the opening.

[0006]

The function of the hanger case that suspends and opens the landing door with the above-described structure, for example, due to the hanger case falling down or twisting, the floor height is extremely high, and the rigidity of the vertical members on both sides of the opening is reduced. Even if you do, you can compensate for this and maintain the same level as before. Therefore, it is not necessary to extend the supporting columns to the vicinity of the upper floor, and it is possible to unify them to a fixed length that can be shared by all floors or other buildings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3 and 4. FIG. 1 is an overall view of a hanger case part of an elevator provided with a landing device of the present invention, FIG.
FIG. 3 shows section xx and section yy of FIG. 1, respectively.
Moreover, FIG. 4 is a zz view of FIG. 1 in the figure
Reference numerals a and 1b are upper and lower platforms, respectively, 2 is a building wall, and 3a and 3b are vertical members provided at both ends of the building opening. 4a and 4b are sills that guide the lower part of a landing door (not shown), and 5a and 5b are horizontal members provided with sills 4a and 4b, which are connected to the vertical members 3a and 3b and form part of a so-called building steel frame structure. is doing. 6 is a hanger case provided with a door rail 7 for guiding the upper part of the landing door, and 8a, 8b
The lower part is fixed to the sills 4a and 4b, and the upper part is a support column for supporting the hanger case 6. Reference numeral 9 is a horizontal bracket connected to the vertical members 3a and 3b, and 10 is a connecting metal fitting for connecting the hanger case 6 and the horizontal bracket 9. 12a, 12b
Is a guide rail for guiding the car 11, 13a, 13
Reference numeral b is a support bracket which is projected from both ends of the extended horizontal bracket 9 and is connected to the connection plates 14a and 14b. According to this configuration, the height of the building floor is increased and the vertical members 3a,
Even if the rigidity of 3b decreases, it can be compensated by the rigidity of the guide rails 12a and 12b, so that it is possible to support the horizontal force from the outside generated via the landing door or the horizontal force generated by an earthquake or the like. On the other hand, the support columns 8a and 8b
Bears the vertical load of the landing door, the hanger case 6 and the like. Dampers 15a and 15b are interposed between the guide rails 12a and 12b and the connection plates 14a and 14b via plates 16a and 16b.
The traveling vibration of is not transmitted to the entrance side. 1
7 is a stopper.

According to this embodiment, it is possible to quickly and inexpensively provide a product that is not influenced by the building side.

[0009]

According to the present invention, (1) since the supporting columns can be unified, the design efficiency is improved, and mistakes in design and manufacturing can be prevented.

(2) Products can be stocked and the delivery time can be shortened.

(3) By stabilizing the product weight, it is possible to improve the workability of transportation and on-site assembly.
