Description

The present invention relates to a working floor constructing device for an elevator parking system.

An elevator parking system is a mechanical parking system that raises and lowers a vehicle along a hoistway and stores the vehicle in a storage rack adjacent to the hoistway. Among elevator parking systems, there is a system in which the longitudinal direction of a pallet stored in a storage rack is different from the direction in which a vehicle enters and leaves the garage. Such an elevator-type parking system is disclosed, for example, in Patent Document 1.

FIG. 1 is an explanatory diagram of a conventional elevator parking system in which the longitudinal direction of a pallet 3 stored in a storage shelf 6 (hereinafter referred to as storage direction X) is different from the loading/unloading direction Y of a vehicle 1. As shown in FIG. In this example, the storage direction X and the loading/unloading direction Y are different by 90 degrees.

In FIG. 1 , (A) is an overall configuration diagram, and (B) is a plan view of the loading/unloading floor 5 immediately before the car 9 arrives at the loading/unloading floor 5 . Also, (C) is a plan view of the loading/unloading floor 5 when the vehicle 1 is loaded/unloaded, and (D) is a top view of the loading/unloading floor 5 when the vehicle 1 is loaded/unloaded without the lifting platform 7. there is

Japanese Patent Application Laid-Open No. 2001-271506

FIG. 2 is an explanatory diagram of a conventional work floor.
FIG. 2A is a plan view of the loading/unloading floor 5 having the cross opening 8. FIG. As shown in this figure, a large cross opening 8 exists in the center of the loading/unloading floor before the cage is installed.
The width Wx and length Ly of one of the cross openings 8 correspond to the size of the pallet 3. For example, the width Wx is approximately 1950 mm and the length Ly is approximately 5200 mm. The width Wy and length Lx of the other rectangle correspond to the size of the cage 9, for example, the width Wy is approximately 2000 mm and the length Lx is approximately 6000 mm.

In order to assemble the elevator parking system at the installation site, it is necessary for a worker to enter the loading/unloading floor 5 and assemble the upper component parts (the parking shelf 6, the cage lifting device, etc.). Therefore, in order to prevent workers from falling into the cross opening 8, a work floor covering the top of the cross opening 8 is required.

Conventionally, Pecobeam (registered trademark), for example, has been used as a work floor covering the cross opening 8 .
FIG. 3 is a schematic diagram showing the configuration of the Peco beam PL. In this figure, (A) shows the outer beam AL, (B) shows the inner beam BL, and (C) shows the Peco beam PL of three joints.
The Peco beam PL has an outer beam AL and an inner beam BL that are removable, and the inner and outer beams are combined to obtain an arbitrary span.

FIG. 2(B) is an example of using a Peco beam PL for the working floor covering the upper part of the cross opening 8 . When constructing a working floor using Peco-beam PL, the maximum span of the cross opening 8 is large (eg length Ly=approximately 5200 mm). Therefore, as shown in FIG. 3(C), three peko beams PL are connected, and the weight of one beam exceeds about 60 kg, which takes time and labor to construct the working floor.

FIG. 2(C) shows a conventional working floor after installation of the cage 9 in the cross opening 8. FIG. When the cage 9 is installed, the upper part of the cage 9 has a rectangular opening only in the center, and the lifting platform 7 exists on both sides thereof.
Therefore, the working floor after installing the cage 9 is different from that shown in FIG. was used to build a scaffold board. Note that "konpane" is an abbreviation for concrete panel, and means a plywood panel with basic dimensions of 900 mm x 1800 mm x 12 mm.
However, when installing the cage 9 and after installing the cage, the conventional work floor is constructed only with a concrete panel and a scaffolding floor by removing the three-tie Peco beam PL shown in FIG. 2(B). It was a stable work floor.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above problems. That is, the first object of the present invention is to provide a work floor constructing apparatus for an elevator type parking system that does not need to be changed before and after installing a platform after installing a cage.
