Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a three-sided frame on the side of an elevator landing entrance, which can be constructed regardless of the process of finishing walls at the entrance and exit of a building, and which can be easily replaced if damaged. Regarding.

0002

[Prior Art] The conventional technology is, for example,
As in Publication No. 6780, there is a method of installing and constructing the three-way entrance frame of multiple parallel elevators and the intermediate panel between the three-sided frames in an adjustable manner, but the wall finish and the three-way entrance frame are Regarding improvements that eliminate conflicting parts,
It wasn't taken into account.

[0003] Also, as in Japanese Utility Model Application Publication No. 63-192381, a method has been proposed in which an elastic material is removably attached to the end face of a three-sided frame at an elevator entrance, but it is difficult to attach and detach the three-sided frame itself and finish the wall. No consideration was given to improvements that would eliminate the area where the three-sided door frames meet.

0004

[Problem to be Solved by the Invention] The three-sided frame for the elevator landing entrance is fixedly installed in the entrance/exit wall opening of a building, but there is a problem with the wall finish, and if the three-sided frame is not installed first, the wall finish will not be possible. cannot be constructed. On the other hand, the material, finish, and shape of the three-sided frame require a high-class design, and it is often difficult to agree on a good deal. As a result, the fabrication and installation of the three-sided frame tended to be delayed, leading to delays in the subsequent wall finishing work, which caused problems that hindered the overall construction process.

[0005] Furthermore, the three-sided frame of the entrance/exit of the elevator hall is often damaged when luggage is brought in or when passengers' bags come into contact with the elevator. At this time, in the case of a light impact, it can be repaired by repainting while the installation is still in place, but in the case of a strong impact, concave dents or large scratches may occur, and in this case, removal, reshaping, or repair may be required.
It will need to be repainted or replaced with a new one. This also applies to other materials and finishes, such as the hairline finish of stainless steel plates, which has the problem of not being able to be completely repaired in a fixed state.

[0006] Also, when refreshing the interior of a building,
Elevator entrance doors are easily removable and can be refreshed, but the critical three-sided frame cannot meet customer needs because the elevator must be stopped for a long time and dismantled and reinstalled, which takes a lot of man-hours. There was a problem.

The present invention provides a three-sided frame for an elevator entrance that eliminates these problems of the conventional type, does not interfere with the construction process, is easy to maintain, and is easy to replace and refresh.

[0008]

[Means for Solving the Problems] In order to achieve this object, the present invention provides two types of frames: a first three-way frame installed at the opening end of the hall entrance/exit wall, and a second three-way frame constituting the hall entrance/exit. The three-sided frame constitutes the three-sided frame of the elevator landing entrance, and the second three-sided frame is detachably and adjustable attached to the first three-sided frame which is fixedly installed in the building.

[0009]

[Function] Unlike the second frame, which requires a high-class design, the first three-sided frame is mainly designed for strength and function, so for example, it can be provided with a painted steel plate or galvanized steel plate, and the shape・Since the size can be determined at the initial stage, it is possible to manufacture and install it in accordance with the construction process. Therefore,
Wall finishes can also be applied without interfering with the construction process.

[0010] Furthermore, since the second three-way frame is adjustably attached to the first three-way frame, even if the first three-way frame is attached in advance, the core on the elevator car side and each equipment There will be no problem with the placement. By adjusting the mutual relationship correctly, the second three-sided frame and main components can be installed efficiently in accordance with the elevator construction schedule.

[0011] Furthermore, since the gap around the hoistway side of the first three-sided frame and the second three-sided frame can be adjusted with fire-proof steel plates, a double fire-proof compartment can be constructed when combined with the landing side. Fire protection performance can be further improved.

Furthermore, since the second three-sided frame is removably attached to the first three-sided frame, even if the main frame, which is a second high-class design item, should be damaged or deformed, it can be removed and repaired. So,
It can be easily constructed in a short time, and by attaching a simple temporary frame, the elevator can be refreshed with the shortest stop time.
