Description

  The present invention relates to a temporary work floor device for an elevator temporarily installed in a hoistway.

  Conventionally, a support member attached to the landing and extending from the landing to the inside of the hoistway, a floor frame provided on the hoistway and supported by the support member, supported by the floor frame, and arranged side by side in the depth direction of the hoistway There is known an elevator temporary work floor device including a plurality of scaffolding plates (for example, see Patent Document 1).

JP 2005-89148 A

  However, since each scaffold board is fixed to the floor frame using bolts or the like, when installing the temporary work floor device of the elevator, first, the scaffold board arranged closest to the landing side is fixed to the floor frame, After that, there is a problem in that an operator must rest on the fixed scaffolding plate and the scaffolding plate adjacent to the fixed scaffolding plate must be fixed to the floor plate.

  This invention provides the temporary work floor apparatus of the elevator which can be installed, without an operator mounting on a scaffold board.

  A temporary work floor device for an elevator according to the present invention is attached to a landing and is supported by the floor frame, a support member that extends from the landing to the interior of the hoistway, is provided on the hoistway, and is supported by the support member. And a plurality of scaffolding plates arranged side by side in the depth direction of the hoistway, and the floor frame has a pair of rails that extend in the depth direction and guide the scaffolding plates.

  According to the temporary work floor device for an elevator according to the present invention, the floor frame is formed to extend in the depth direction and has a pair of rails for guiding the scaffolding plate. All the scaffolding plates can be attached to the floor frame by placing the scaffolding plates on and pushing the scaffolding plates to the hoistway side. Thereby, the temporary work floor apparatus of an elevator can be installed, without an operator mounting on a scaffold board.

It is a side view which shows the temporary work floor apparatus of the elevator which concerns on Embodiment 1 of this invention. It is a perspective view which shows the floor frame and scaffold board of FIG. It is a side view which shows a mode that the temporary work floor apparatus of the elevator of FIG. 1 is assembled.

Embodiment 1 FIG.
1 is a side view showing a temporary work floor device for an elevator according to Embodiment 1 of the present invention. The temporary work floor device for an elevator includes a support member 1 attached to a landing 101 on the top floor, a floor frame 2 provided on the hoistway 102 and supported by the support member 1, and a plurality of scaffolds supported by the floor frame 2. And a plate 3.

  The support member 1 is arranged extending from the landing 101 to the inside of the hoistway 102. The support member 1 has a pair of frames 11 standing on a landing 101, a lower end connected to the frame 11, an upper end connected to the ladder 12 extending inside the hoistway 102, and an upper end connected to the frame 11. The diagonal member 13 whose lower end is connected to the ladder 12 and the support member 14 whose lower end is connected to the frame 11 and whose upper end extends into the hoistway 102 are provided.

  Each frame 11 is disposed away from the entrance / exit of the entrance. The lower end of the frame 11 is fixed to the landing 101. The upper end portion of the frame 11 is fixed to a wall 103 located above the landing entrance.

  The ladder 12 is disposed so as to be inclined with respect to the horizontal plane so that the upper end portion is further away from the landing 101 in the depth direction of the hoistway 102 than the lower end portion. Here, the depth direction of the hoistway 102 is the depth direction when the hoistway 102 is viewed from the landing 101, and is the direction of arrow A in FIG. The operator can attach and detach the scaffold board 3 to the floor frame 2 by climbing the ladder 12. The upper part of the ladder 12 is connected to the floor frame 2.

  The diagonal member 13 is disposed so as to be inclined with respect to the horizontal plane such that the lower end portion is further away from the landing 101 in the depth direction of the hoistway 102 than the upper end portion. By connecting the diagonal member 13 to the ladder 12, the ladder 12 is maintained in an inclined state.

  The support member 14 is disposed so as to be inclined with respect to the horizontal plane so that the upper end portion is further away from the landing 101 in the depth direction of the hoistway 102 than the lower end portion. The upper end portion of the support member 14 is further away from the landing 101 in the depth direction of the hoistway 102 than the upper end portion of the ladder 12. The upper end portion of the support member 14 is connected to the floor frame 2.

  The floor frame 2 is disposed along a horizontal plane. Therefore, the scaffold board 3 is also arrange | positioned along the horizontal surface.

  FIG. 2 is a perspective view showing the floor frame 2 and the scaffold plate 3 of FIG. The floor frame 2 has a pair of horizontal beams 21 extending in the depth direction of the hoistway 102 and a pair of rails 22 provided on each horizontal beam 21. Each rail 22 is formed extending in the depth direction of the hoistway 102. Moreover, the rail 22 guides the scaffold board 3. Each rail 22 is formed with a groove 23 extending in the depth direction.

  The scaffold plate 3 includes a plate main body 31 and a convex portion 32 provided in the plate main body 31 and inserted into the groove 23. The scaffold plate 3 is slidable in the depth direction of the hoistway 102 with respect to the floor frame 2 in a state where the convex portion 32 is inserted into the groove 23.

  The floor frame 2 includes a regulating member (not shown) that restricts the movement of the scaffold plate 3 in the depth direction of the hoistway 102 when all the scaffold plates 3 are attached to the floor frame 2.

  Next, the procedure for assembling the temporary work floor device for the elevator will be described. FIG. 3 is a side view showing a state where the temporary work floor device of the elevator shown in FIG. 1 is assembled. First, the worker 104 installs the support member 1 on the landing 101 with the floor frame 2 attached to the support member 1.

  After that, the worker 104 is placed on the ladder 12, attaches the scaffold board 3 to the portion of the floor frame 2 closest to the landing 101, and slides the scaffold board 3 attached to the floor frame 2 to the hoistway 102 side. Thereafter, the next scaffold plate 3 is attached to the floor frame 2 and slid in the same manner. When all the scaffolding plates 3 are attached to the floor frame 2, the assembly of the temporary work floor device for the elevator is completed.

  As described above, according to the temporary work floor device for an elevator according to Embodiment 1 of the present invention, the floor frame 2 has a pair of rails 22 that extend in the depth direction and guide the scaffold plate 3. Therefore, the worker 104 can attach all the scaffold boards 3 to the floor frame 2 by placing the scaffold boards 3 on the floor frame 2 and pushing the scaffold boards 3 toward the hoistway 102 side. Thus, the temporary work floor device for the elevator can be installed in a state where the worker 104 is at the landing 101 without the worker 104 being placed on the scaffold plate 3.

  Further, the rail 22 is formed with a groove 23 extending in the depth direction of the hoistway 102, and the scaffold plate 3 has a convex portion 32 inserted into the groove 23. 23, the scaffold plate 3 can be easily guided in the depth direction of the hoistway 102, and the efficiency of the installation work of the temporary work floor device for the elevator can be improved.

  In the first embodiment, the structure in which the groove 23 is formed in the rail 22 and the scaffold plate 3 has the convex portion 32 inserted into the groove 23 has been described. However, the groove is formed in the scaffold plate 3, and this groove The structure which the rail 22 has the convex part inserted in may be sufficient.
