Description

  The present invention relates to a elevator plate for an earthquake-proof building elevator.

According to the Building Standards Law, the size from the car sill to the Fescher plate has been established as “125 mm or less”. However, in the case of a base-isolated structure, this standard may not be satisfied when an earthquake occurs.
In a base-isolated structure, the base-isolated building absorbs shaking when an earthquake occurs. At that time, since the relative displacement occurs between the base building and the seismic isolation building, the elevator car door does not satisfy the standard that the dimension from the elevator car entrance to the fisher plate is 125 mm or less and is not at the elevator landing. There was a risk that the user would fall if the was opened.
In addition, there is a risk that the elevator car and the fisher plate will be too close to each other due to the relative displacement between the base building and the base-isolated building at the time of the earthquake.
Therefore, there is a need for an elevator fisher plate that can maintain the distance between the elevator and the fisher plate even in the event of an earthquake.

For example, Japanese Unexamined Patent Application Publication No. 2004-91197 and Japanese Unexamined Patent Application Publication No. 2007-8610 address such problems.
JP 2004-91197 A JP 2007-8610 A

The configuration described in Japanese Patent Application Laid-Open No. 2004-91197 has a problem that the number of parts for attaching the fescher plate is large, and time is required for installation work on site.
In addition, since the configuration described in Japanese Patent Application Laid-Open No. 2007-8610 is a structure in which one facet plate is attached between floors, the distance between floors (that is, the length of the facet plate) is up to about 2500 mm. Although it can respond, when the distance between floors (the length of the Fescher plate) exceeds 4000 mm, there is a problem that workability and installation workability deteriorate.

  One of the main objects of the present invention is to solve the above-mentioned problems, and keeps the distance from the elevator constant following the displacement caused by the occurrence of an earthquake, and the number of parts is small and the installation work is quick. The main purpose is to realize a fascia plate that can be easily mounted even if the distance between floors is long.

The elevator plate according to the present invention is:
An upper plate fixedly attached to any of the building structure surrounding the elevator hoistway and the rail connecting frame attached to the elevator rail;
A lower plate fixedly attached to either the building structure or the rail connection frame;
A middle plate disposed between the upper plate and the lower plate;
The upper plate and the middle plate are slidably connected in the left-right direction of the elevator hoistway, and the lower plate and the middle plate are slidably connected in the left-right direction of the elevator hoistway. And

  The fescher plate according to the present invention is composed of an upper plate, a middle plate, and a lower plate that are slidable in the left-right direction, so that the distance from the elevator can be kept constant following the displacement that occurs when an earthquake occurs. In addition, even when the floor is long, it is easy to install due to the divided structure.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a state in which the Fescher plate 1 according to the present embodiment is installed in a hoistway 3 with a seismic isolation building 12 from the side (the traveling direction of the elevator car 20 is the vertical direction). is there.
As described above, the festival plate 1 is disposed between the floors (between the upper and lower landings 10), and even if there is a space between the elevator car 20 entrance and the building wall 23 of the building, Is located between the building wall 23 and the entrance of the elevator car 20, the distance from the elevator car 20 (the car front line 21) is kept below 125 mm, and the door opens in the hoistway 3 due to an accident, etc. However, the user is prevented from falling into the hoistway 3.
In FIG. 1, rail connection frames 2 are arranged between the floors. As shown in FIG. 2, an elevator rail 4 and a counterweight rail 22 are attached to the rail connecting frame 2. FIG. 2 is a view showing the rail connecting frame 2 from above (or below).
In FIG. 1, there are one fisher plate 1 at the top and bottom of the rail connecting frame 2, and two fisher plates 1 are attached between the floors.
When an earthquake occurs, a relative displacement occurs between the elevator rail 4 and the building, and the distance between the fisher plate 1 and the elevator car 20 exceeds 125 mm. Therefore, the earthquake plate 1 is not attached only to the building structure surrounding the elevator hoistway 3 but is attached to the elevator rail connecting frame 2 on either side of the upper and lower parts and attached to the building structure side on the other side. Even if the elevator car 20 sways in the depth direction, the elevator plate 1 follows the movement of the elevator rail 4 via the rail connecting frame 2 so that the distance between the elevator car 20 and the elevator plate 1 is 125 mm or less.

Further, for example, as shown in FIG. 9, the upper end or lower end of the fisher plate 1 is anchored via a fitting 33, a bolt 31, and a nut 32. It is conceivable to attach to the building wall 23 side with bolts 34.
In addition, the attachment method of the Fescher plate 1 and the rail connection frame 2, and the attachment method of the Fescher plate 1 and the building wall 23 are not restricted to what is shown in FIG.8 and FIG.9.

Further, there are cases where there is no entrance / exit near the base-isolated building 12, and the floor space may be longer than usual. Therefore, the fisher plate 1 is divided into upper and lower parts to facilitate the attachment of the fisher plate 1 even in the case of a long floor.
In order to follow the shaking caused by the earthquake, the Fescher plate 1 needs to absorb the displacement generated by the earthquake. As a structure for absorbing the displacement, the Fescher plate 1 according to the present embodiment has the structure shown in FIG.
That is, the fescher plate 1 according to the present embodiment is fixed to either the building structure or the rail connection frame 2 and the upper plate 1a fixedly attached to either the building structure or the rail connection frame 2.
