DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled three-dimensional structure in which a parking floor covering a plurality of floors is constructed underground, and a parking vehicle is driven to move to each parking floor.
The present invention relates to a method for constructing an underground parking lot .

[0002]

2. Description of the Related Art In recent years, the shortage of parking lots accompanying the remarkable spread of vehicles has developed into a social problem. In particular, in urban areas such as large cities, the demand for parking lots has increased due to the serious shortage of land. doing. As one means for overcoming this problem, a plurality of parking floors (about 1 to 3 layers) are constructed underground to form a three-dimensional structure, and the land is effectively used.

Such a three-dimensional underground parking lot includes a self-propelled type in which a vehicle travels to a parking lot partitioned on a parking floor,
A mechanical type in which a lift-type parking garage for parking one vehicle is assembled in a plurality of stages is roughly classified, and a combined type in which a mechanical type is installed on a parking floor of a self-propelled type has also been proposed.

[0004]

In the case of the above-mentioned self-propelled type, the area required is extremely large (for example, 40 to 50 m2) in terms of one vehicle because a traveling path to a parking lot is required. Inefficiency makes it difficult to secure construction space, especially in large cities.

Further, in the case of the mechanical type, an operator who safely raises and lowers the parking space is absolutely necessary, and only one vehicle can be processed at a time, and the processing time is simply parked in the parking space. Inefficiency such as taking longer than the self-propelled type alone is a problem. In addition, since a breakdown is inevitable, it is difficult to apply the method to a public parking lot for an unspecified number of users.

Further, in the case of the above-mentioned combination type, there is an advantage that the parking density is higher and the operating cost per vehicle is reduced as compared with the case of the simple self-propelled type, but the problem with the operator remains.

[0007] When considering the business balance including the operation cost, underground parking lots are generally inconvenient due to the construction cost, which often leads to a problem that the funds cannot be recovered. Costs are high, and it is strongly desired to reduce construction costs.

Further, from a structural point of view, there are only about three layers (three basement floors) to secure the strength, and there is a limit in improving the area efficiency.

The present invention has been made in view of the above-mentioned circumstances, and does not require an operator, has no fear of failure, and
Effective self-propelled system that can improve business profitability and area efficiency

That is, the floors 7a and 7b and the traveling paths 13 are continuously and horizontally maintained, and the respective traveling paths 13
It is assumed that the wall is blocked by the shared wall 1A.

In the case of the second parking lot P2, the upper floor 7
At the right end of a, one elevator space 8 provided with an elevator 11 and an emergency staircase 12 is provided. Although the hoistway 5 is constructed on the end wall 1B side, there is no hoistway 5 on the connection side common wall 1A side, and the parking lot 14 is partitioned. Further, the second parking lot P2 is different from the first parking lot P1 in that the upper floor 7a of the top floor does not have an entrance 15a and an exit 15b to the ground, and the lower floor 7b of the top floor has no cubicle 18. Instead, the parking lot 14 is partitioned.

When the second parking lot P2 is connected to the first parking lot P1 as described above, a portion of the shared marble wall 1A corresponding to the traveling path 13 of each of the parking lots P1, P2 is opened. To form a continuous port 19,
, The two running paths 13 are connected. In addition, a part of the hoistway 5 on the shared wife wall 1A side of the first parking lot P1 is set as a staircase 20, and both sides are remodeled into a horizontal parking lot 14a.

As described above, the first and second parking lots P1,
A parking lot P composed of P2 is formed. In this parking lot P, the vehicle advances from the entrance 15a to the topmost parking floor 7 of the first parking lot P1, and a continuous running path of each parking lot P1, P2. 13 and each of the down-only roads 5b at both ends, spirally turn down the parking floor 7 in the direction of the arrow shown in FIG. 1 and FIG. Park against.
