DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for installing underground parking facilities and an installation work vehicle used for the method. Recently, with the shortage of land in urban areas and the increase in vehicles, the following underground parking lots have begun to be used in order to store as many cars as possible in the underground space of buildings. As an example of the underground parking lot, as shown in FIGS. 10 to 12, an elevator pit 101 and a parking space 102 are dug underground, and a guide rail 103 is installed in the elevator pit 101, and a lift 104 is mounted so as to be able to move up and down. I have. The parking space 102
The parking frames F are arranged in a grid pattern and installed on one or more layers. For example, in the example shown, pit 10
Except for the part 1, 19 parking frames F are installed on the floor 107 of the parking space 102, and 19 parking frames F are also mounted on the second layer supported by the columns 108. Then, the pallet P is left with two places indicated by “empty”.
No. 1 to 17 are placed on the first parking frame F, and No. 18 to
35 is placed on the parking frame F of the second layer. The pallets P are moved in the front-rear direction (the longitudinal direction of the pallets P) and in the lateral direction (the width direction of the pallets P) by driving wheels mounted on the parking frame F, and each pallet P is moved vertically and horizontally. , To get in and out of the car. The number of parking frames and the number of parking frames are of course arbitrary.

2. Description of the Related Art In a multi-layered underground parking lot as described above, a support 108 is set up between a number of parking frames F arranged on a floor 107, and a second-layer parking frame is placed thereon. Construction must proceed in the order of fixing F. It is necessary to construct the third and higher parking frames in the same manner. However, because the ceiling height of the underground parking lot is low, it is not possible to bring a crane truck or the like. Also,
When a large number of unit-type parking frames F are arranged on the floor surface 107, ordinary carts and forklifts cannot be used at all. Therefore, conventionally, as shown in FIG. 13, a chain block 115 is sequentially suspended on a large number of suspension pieces 116 previously mounted on the ceiling, and the second-level parking frame is suspended using the chain blocks 115. Convey while lowering,
Had to be installed. Also, once the second-level parking frame is carried into the predetermined position, the chain block
It is difficult to install a second-layer parking frame because the support 108 is in the way if it is lifted with 115 or the like. For this reason, conventionally, the second-level parking frame is used to support the 108
Had to be moved in the air with a chain block 115 over his head.

[0003]

However, according to the above-mentioned conventional method, a large number of hanging pieces 116 must be attached to the entire ceiling of the basement in advance, which is extremely complicated. Further, although the parking frame usually weighs a little over a ton, it is dangerous to carry such heavy parts repeatedly to the desired position while repeatedly moving in the air from the chain block 115 to the chain block 115. However, there was a problem that the work was too laborious.

In view of the circumstances described above, the present invention measures labor saving, improves safety, and integrates transport and installation work in the installation work of the second-layer parking frame.
It is an object of the present invention to provide an efficient second-layer parking frame installation method and an installation work vehicle used for the method.

[0005]

According to the present invention, there is provided a method of installing a multi-layered underground parking facility, comprising the steps of (a) installing a lower-level parking frame in a parking frame and erecting a pillar at each corner of the parking frame; b) a step of mounting an installation work vehicle provided with a lift device on the upper surface of the dummy pallet on the lower parking frame, (c) pushing the upper parking frame higher than the support by the lift device, and installing the vehicle. And (d) lowering the lifting device at the installation position and attaching an upper parking frame to the support. Further, the installation work vehicle of the present invention is characterized by comprising a dummy pallet having substantially the same structure as a pallet for loading an automobile, and a lifting device installed on the dummy pallet.

[0006]

According to the installation method of the present invention, if the parking frame is first installed on the floor of the first-level underground parking lot (the process
(a)), the pallet on which the car is placed can be transported to a desired position by driving the driving wheels of the parking frame with a temporary power supply or the like. In the installation method of the present invention, an installation work vehicle including a dummy pallet having the same structure and a lifting device is mounted instead of a normal pallet (step (c)).
If the second-layer parking frame is placed on the push-up lift device of the installation vehicle and pushed up high (process (d)), it can be easily transported to the destination through the columns without interfering with the columns. can do. For this reason, a pillar was erected (process
(b)) Even afterward, it can be easily and safely transported automatically to the desired position (step (d)). In addition, the second-level parking frame can be lowered onto the pillars by the lifting device, and can be installed on the spot, eliminating the need for a large number of hanging pieces and making it necessary for the chain block to move unstable in the air. Is also gone.

Next, since the installation work vehicle of the present invention uses a dummy pallet having substantially the same structure as a normal pallet, when the drive wheels of the parking frame are rotated using a temporary power supply or the like, the drive wheels are driven. The dummy pallet placed thereon can be transported to a predetermined position. In addition, since the lifting machine is installed, the heavy parking frame can be pushed up and down stably, and the second-layer parking frame can be installed on the pillar. Easy to do. As described above, the method of the present invention effectively utilizes the lower-level parking frame previously installed among the members of the parking facility, which is originally a facility for transporting a heavy object called an automobile, to a predetermined position, and subsequently installs it. This simplifies the transportation and installation work of the upper-level parking frame.
