Description

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 underground parking lot of a type in which a parking floor extending over multiple floors is constructed in the basement and a parked vehicle is run to move to each parking floor. Regarding the construction method.

[0002]

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

Such a three-dimensional underground parking lot is a self-propelled type in which a vehicle travels to a parking lot divided on a parking floor.
It is roughly classified into a mechanical type in which an elevating type parking pedestal for parking one vehicle is assembled in a plurality of stages, and a combined type in which a mechanical type is installed on a self-propelled parking floor is also proposed.

[0004]

In the case of the above-mentioned self-propelled type, the required area is extremely large when converted per vehicle (for example, 40 to 50 m2) because the traveling path to the parking lot is required. Due to poor efficiency, it is difficult to secure construction space especially in large cities.

Further, in the case of the mechanical type, an operator for safely raising and lowering the parking table is absolutely necessary, and only one vehicle can be processed at a time, and the processing time is simply to park in the parking space. The problem is inefficiency that it takes longer than the self-propelled type. In addition, since breakdowns are unavoidable, it is difficult to apply the method to public parking lots for a large number of unspecified users.

Further, in the case of the combined use type, there is an advantage that the parking density is higher and the operating cost per car is reduced as compared with the mere self-propelled type, but the problem regarding the operator remains as it is.

Considering the business balance including its operating cost, the construction cost of an underground parking lot is generally high, which often causes a problem that the funds cannot be collected. Since it costs money, there is a strong demand for reduction of construction costs.

From the structural point of view, there are only three layers (three basements) 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 various circumstances, and a structure and its structure that can improve business profitability and area efficiency in a self-propelled three-dimensional underground parking lot that does not require an operator and has no fear of failure. Its main purpose is to provide a construction method.
