Abstract

(57) [Summary] [Purpose] To provide a hatch door fixing bracket for elevators that can be used for hatch door remodeling work without installing a doorway curing device. [Structure] A U-shaped bracket 11 arranged so as to sandwich the upper end of the upper frame of the three-way frame 2 and the upper end of the hatch door 4,
The hole 13 formed so as to penetrate the side surface portion 12 of the U-shaped bracket 11 facing the hatch door 4 and the hole 1
When the hatch door 4 is remodeled, it is equipped with a bolt 14 that is inserted into the hatch door 3 and has a tip capable of pressing the hatch door 4.
Is fastened to the upper end of the upper frame of the three-way frame 2 via the hatch door fixing member 10. [Effect] Since the existing hatch door itself serves as a partition wall for the hoistway, there is no need for any other panel material forming the partition wall, and the efficiency of the hatch door modification work can be improved and the cost can be reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator hatch door fixing bracket, and more particularly to an elevator hatch door fixing bracket suitable for use during elevator removal and new construction work.

[0002]

[Prior Art]

 Generally, the work to modify the hatch door of an existing elevator is carried out in a building that is in operation. For this reason, it is necessary to take all possible measures to secure a fire-prevention section during construction, prevent users from entering, and prevent dust and shavings from spreading.

Conventionally, as shown in FIG. 3, the entrance / exit has been cured by assembling a panel material 3 that completely covers the three-way frame 2 forming the hall 1 in the hall 1 of the elevator. 4 is a hatch door, 5 is a door hanger, 6 is a rail, and 7 is a pocket for holding the rail 6.

The panel material 3 constituting the above-mentioned entrance / exit curing device is perpendicular to the floor surface and the wall surface, and is provided with two side plates 3 a standing on both outsides of the three-way frame 2 and side plates 3 a. It is composed of a front plate 3b and a ceiling plate 3c which are connected to each other and have a door that can be moved in and out. After arranging the panel material 3 like this, the hatch door 4 is removed, the pocket 7 is removed, and the wall of the building is smoked, and then a new hatch door 4 is installed.

[0005]

[Problems to be solved by the device]

 By the way, in conventional elevator entrance / exit curing, the panel material 3 configured as described above is installed on all floors, but the number of elevator hatch door remodeling works has increased significantly, and high-floor buildings are frequently used. In recent years, there are demands for improvements in various aspects such as workability, safety, and economic efficiency. Considering workability, the panel material 3 is installed on each floor, and therefore the assembly of this panel material 3 is required. However, dismantling took a very long time, and the cost was very expensive.

The present invention is intended to solve the above-mentioned conventional problems, and an object thereof is to provide a hatch door fixing metal fitting for an elevator capable of performing a hatch door remodeling work without providing a panel material as an entrance / exit curing device. There is

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is used when remodeling a hatch door of an elevator, and a U-shaped bracket arranged so as to sandwich the upper end of the upper frame of the three-way frame forming the landing and the upper end of the hatch door. And a hole formed so as to penetrate a side surface portion of the U-shaped bracket that faces the hatch door, and a bolt that is inserted into the hole and has a tip capable of pressing the hatch door.

[0008]

[Action]

 Since the hatch door fixing bracket according to the present invention is configured as described above, when modifying the hatch door, remove the door hanger connected to the pocket rail, hold the hatch door by hand, and use the U-shaped bracket. Insert the upper edge of the upper frame of the three-way frame and the upper edge of the hatch door, and tighten the bolts to fasten the upper edge of the upper frame of the three-way frame and the upper edge of the hatch door by pressing the bolts. It serves as a partition wall for the hoistway, functions in the same way as a conventional entrance / exit curing device, and does not require any other panel material forming a partition wall.

[0009]

【Example】

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

FIG. 1 is a cross-sectional view of a landing entrance / exit showing a state when the hatch door is modified. 2 is a three-way frame, 4 is a hatch door, 6 is a rail, 7 is a pocket for holding the rail 6, and these are shown in FIG. Same as shown.

Reference numeral 10 denotes a hatch door fixing metal fitting of the present invention, which is a hole formed so as to penetrate a U-shaped bracket 11 and a side surface portion 12 of the U-shaped bracket 11 facing the hatch door 4 as shown in FIG. 13 and a bolt 14 that is inserted into this hole 13 and whose tip can press the hatch door 4, and a nut 15 that is welded to the side surface 12 of this U-shaped bracket 11. The bolt 14 and the nut 15 are screwed together. Has been done.

When the hatch door 4 is modified, the door hanger 5 shown in FIG. 3 is removed and the hatch door 4 is held by hand, and the upper end of the upper frame of the three-way frame 2 and the upper end of the hatch door 4 are closed. It is carried out by the character-shaped bracket 11 and the bolt 14 is tightened. As a result, the nut 15 and the bolt 14 welded to the side surface portion 12 of the U-shaped bracket 11 are screwed together, the bolt 14 penetrates the hole 13 formed so as to penetrate the side surface portion 12, and By pressing the upper end of the frame and the upper end of the hatch door 4, the upper end of the upper frame of the three-way frame 2 and the upper end of the hatch door 4 are fastened. FIG. 1 shows the state at this time.

Then, the rail 6 and the pocket 7 are removed, the wall of the building is scavenged if necessary, and replaced with a new rail 6, the pocket 7 and the door hanger 5, and in this state, the bolt 14 is loosened and the hatch door fixing metal fitting is attached. Remove 10 and replace with a new hatch door 4, and connect the door hanger 5 and the hatch door 4 described above.

In the embodiment configured in this manner, when the pocket 7 is removed or the wall of the building is picked up, the hatch door 4 is firmly held via the hatch door fixing metal fitting 10. It forms a partition wall for fire protection and has a dustproof function for the landing side. Therefore, no other panel material for forming the partition wall is required.

[0015]

[Effect of the device]

 Since the structure is as described above, when modifying the hatch door, the existing hatch door can be fastened to the upper end of the upper frame of the three-way frame, which makes it possible to connect pockets, rails, and door hangers independently of the existing hatch door. It can be removed and installed, and the existing hatch door itself forms a bulkhead for the hoistway and has a fireproof function, and also has a dustproof function for the landing side, so a special panel material etc. that forms a bulkhead is required. Not only that, the efficiency of this hatch door remodeling work can be improved, and the cost for remodeling is expensive compared to the past.
