DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device and a fixing method for a temporary lift hoistway, and more particularly to a fixing device and a method using a window frame of a building.

[0002]

2. Description of the Related Art When a building has only one hoistway such as an elevator, an alternative means of transportation must be provided in repair work or the like that requires long-term suspension of the elevator. Specifically, for example, hospitals often serve meals for inpatients using elevators, and it is quite labor intensive to perform all meals manually, so a temporary lift hoistway is an alternative. It is desirable to provide a transportation means. Since the hoistway is intended for temporary use only during the period required for construction (for example, one month), it must be easily installed to minimize the spread of the construction to the building.

FIG. 4 shows how a conventional temporary lift hoistway is attached. In the figure, 1 is a hoistway,
It is fixed to the building with fixing fittings 12. Reference numeral 13 denotes a building opening that is perforated for an entrance.

FIG. 5 is an enlarged view of the fixing bracket 12 of the temporary lift hoistway shown in FIG. In the figure, 9 is a steel frame of the hoistway, 12a is a long hole for attaching the hoistway to the building, and 12b is a long hole for a bolt fixing the hoistway. Reference numeral 14 denotes an anchor bolt for fixing.

When the temporary lift hoistway 1 is attached to a building, the anchor 12 is driven into the building through an elongated hole 12a of a fixing bracket 12, and the hoistway is similarly passed through the elongated hole 12b through a bolt. Secure with bolts and nuts. In addition, each attachment can be finely adjusted.
After fixing the temporary lift hoistway, meals are served using the building opening 13 as an entrance.

[0006]

However, in the above prior art, anchor bolts are required to be installed on the outer wall of the building to fix the hoistway, so that noise reduction during construction and repair of the outer wall after removing the temporary lift hoistway are required. There was a problem that required.

Further, it is necessary to make a hole for an entrance on the outer wall of the building, and it is necessary to fill the outer wall of the building after removing the temporary lift hoistway.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to fix a temporary lift hoistway without drilling holes or driving anchor bolts in a building. And a fixing method.

[0009]

In order to achieve the above object, a first invention is a fixing device for fixing a temporary lift hoistway along an outer wall of a building, wherein a lower end of a window frame of the building is fixed. A table-shaped fixing bracket having a fixing portion that straddles and placed on the lower end of the window frame, and provided on the indoor side and the outdoor side of the fixing portion of the fixing bracket, respectively, and the fixing bracket is tightened from both sides to allow the fixing bracket to be mounted on the window. It is characterized by having a bolt fixed to the lower end of the frame and a nut provided on the outdoor bolt and holding the temporary lift hoistway together with the outdoor fixing part.

In order to achieve the above object, a second invention is a method for fixing a temporary lift hoistway along an outer wall of a building, wherein a table-like fixing bracket is connected at one end to the indoor side. The temporary frame is fixed to the lower end of the window frame of the building so that the end is located on the outdoor side, the temporary lift hoistway is fixed to the outdoor side of the fixing bracket, and the window frame is used as a doorway for the temporary lift, and the table-like The fixing bracket is used as a table at the entrance.

[0011]

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

FIG. 1 shows a state in which a temporary lift hoistway is attached to a building using the fixing device of the present embodiment. In the figure, reference numeral 1 denotes a temporary lift hoistway. The temporary lift hoistway is installed by skillfully using a window frame of the building, instead of being installed on the outer wall of the building using anchor bolts as in the related art. .

FIG. 2 shows a fixing device for attaching the temporary lift hoistway to the window frame in FIG. In the figure, reference numeral 2 denotes a table-shaped fixing bracket, 3 denotes a fixing plate, and the fixing plate 3 is attached to the fixing bracket 2 by fastening bolts (and nuts) 7. When the table-shaped fixing bracket 2 and the fixing plate 3 are attached to the lower end of the window frame, one end is located inside the room and the other end is located outside the room. Reference numeral 4a denotes a holding bolt provided at the indoor end of the fixed plate 3, and 4b denotes a holding bolt provided at the outdoor end of the fixed plate 3. Reference numeral 5 denotes a lock nut inserted into each of the holding bolts 4a and 4b.
Reference numeral 6 denotes a holding plate that is inserted into the holding bolt 4b on the outdoor side to sandwich and fix a steel frame constituting the hoistway.

FIG. 3 shows an engagement state between the building and the temporary lift hoistway when the temporary lift hoistway is installed on the window frame of the building using the fixing device shown in FIG. In the figure, 8 is a lower end of a window frame of a building, 9 is a steel frame of a temporary lift hoistway, 10 is a guide rail installed in the hoistway,
Reference numeral 11 denotes a temporary lift.

In such a configuration, the fixing plate 3 attached to the table-shaped fixing bracket 2 is placed so as to straddle the lower end 8 of the window frame, and the holding bolt 4 provided on the fixing plate 3 is provided.
The table-shaped fixture 2 is fixed to the lower end 8 of the window frame by tightening a and b. The steel frame 9 constituting the hoistway is composed of the holding plate 6 of the holding bolt 4 b and the fixing plate 3.
And fix it by tightening the lock nut 5. As a result, the temporary lift hoistway
It can be fixed to a window frame of a building without using an anchor bolt or the like, and the window frame can be used as a door for a temporary lift as it is. Furthermore, since the table-shaped fixing bracket 2 is fixed to the lower end of the window frame such that one end is located on the indoor side, the fixing bracket 2 can be used as it is as a table for carrying in and out.

[0016]

As described above, according to the present invention,
By using the existing building window frame, it is not necessary to make a hole in the outer wall, and the hoistway can be fixed without damaging the outer wall of the building.

This eliminates the generation of noise due to the installation of anchor bolts and the drilling work for the entrance and exit, and also eliminates the need to perform repair work on the outer wall after removing the temporary lift hoistway.

Further, since the fixing bracket can be used also as a table for the entrance, the table installation parts are not required, and the construction time can be shortened.
