Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an underground parking lot.

(Prior Art) In recent years, the number of automobiles in Japan has increased significantly, leading to a chronic shortage of parking spaces.

However, it has become extremely difficult to meet the demand for parking spaces due to the recent rise in land prices, rising construction costs, and issues such as securing green space, as well as the fact that parking lot rents cannot be expected to be that high. ing.

In recent years, multilevel parking lots have been constructed underground in order to make effective use of land, which has risen in price.

Conventional underground parking lots are mostly self-propelled, which have a low parking space efficiency due to the area taken up by passageways, and also require disaster prevention equipment such as ventilation and fire extinguishing. Therefore, in order to improve the parking lot, an increasing number of parking lots are constructed in which a rectangular parallelepiped structure is built underground and a merry-go-round type multilevel parking device is installed inside the structure.

(Problem to be Solved by the Invention) However, since the underground structure in the conventional underground parking lot is a rectangular parallelepiped, a bending moment is generated due to the earth pressure and water pressure acting on the structure from the outer circumferential surface, and it is necessary to deal with the stress. Construction costs for structures increase.

Furthermore, since a merry-go-round type parking device is used, it takes a lot of time for cars to enter and exit the parking lot, making it difficult to accommodate a large number of cars.

The present invention has been proposed in view of the problems of the prior art, and its purpose is to provide a structure that is rational and has excellent workability.
It provides an economical underground parking lot that has low construction costs, can accommodate a large number of cars, and allows quick entry and exit of cars.

(Means for Solving the Problems) In order to achieve the above object, the underground parking lot according to the present invention constructs a cylindrical concrete wall underground and has a through hole in the center of the wall. The parking lot is constructed by disposing a plurality of layers of disc-shaped parking floors, and disposing a lifting device for carrying in and out of cars so that it can be raised and lowered over a central through hole of each floor.

According to a second aspect of the invention, the vehicle loading and unloading lifting device is constituted by an elevator that rotates around a vertical axis so that the vehicle can be loaded and unloaded easily and quickly.

The invention according to claim 3 comprises the elevator and a pallet mounted on a horizontally rotating parking bed.

(Function) As described above, in the underground parking lot according to the present invention, the concrete frame wall constructed underground is cylindrical, and the soil and water pressure act from its outer peripheral surface, so the bending stress applied to the frame wall is small. , the compressive stress is predominant, and the circular cross section distributes the stress evenly, saving the construction cost of the wall.

Further, a multi-layer disk-shaped parking floor is provided on the main body wall, and a lifting device for carrying in and out of cars is provided across the central through hole of each floor, and each of the above-mentioned layers Vehicles can be loaded and unloaded easily and quickly using horizontally movable pallets installed on each parking floor.

The invention according to claim 2 is characterized in that the elevator for carrying in and out of a car is constituted by an elevator that rotates around a vertical axis, so that the elevator can be raised and lowered to a predetermined parking floor, and at the same time, the elevator can be rotated around the vertical axis. Then, the car is transferred from the elevator to the parking floor via a pallet that moves horizontally to the required position.
Alternatively, by loading the car onto the elevator from the same parking floor, it is possible to enter and exit the garage easily and quickly.

In the invention of claim 3, after raising and lowering a car loading/unloading device to a parking floor that rotates in a predetermined horizontal direction, the parking floor is rotated, and the car is moved between the floor and the elevator. By horizontally moving the pallet on which the vehicle is mounted, vehicles can be easily and quickly taken in and out of the warehouse.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Furthermore, a lifting device (4) for carrying in and out of cars is disposed across the central through hole (3a) of each floor (3) so as to be able to be raised and lowered, and the lifting device (4) is configured to rotate around a vertical axis. It is configured. (See Figures 1 and 2) In the illustrated embodiment, as described above, the frame wall (1) constructed underground is configured in a cylindrical shape.
The structural wall (11) has a small bending stress due to earth pressure and water pressure applied to its outer circumferential surface, and compressive force is dominant, and its circular cross section distributes the stress evenly, so the construction cost of the structural wall can be reduced. Also, since it has a circular cross section, construction is easy, and it can be constructed using continuous underground walls, caissons, etc.

Furthermore, in the embodiment, a central through hole (3
A) is equipped with a lifting device (4 ribs) for loading and unloading cars, so when entering the warehouse, the car is loaded onto the lifting device (4) and moved to the required parking floor (3), and at the same time The lifting device (
4) is rotated around the vertical axis to a required position as shown in (4') in Figure 1, and at the same position the car is moved from the lifting device (4) to the parking floor (3) and both (4) )(3
It is transferred to a horizontally movable pallet (5) that moves between 1 and 2, and is stored on the river bed (3).

When leaving the parking lot, the lifting device (4), which has been moved to the required parking floor (3), is rotated around the vertical axis from the riverbed (3) to a position directly facing the car that is about to leave the parking lot. , a pallet on which a car is mounted on the floor (3) (
5) is transferred to the elevating device (4) and taken out of the warehouse.

The underground parking lot is unmanned, and the elevator (4) is installed in the underground parking lot.
) can be used 24 hours a day by allowing the user to enter and exit the car using remote control.

In addition, since it is unmanned, there is no need for ventilation equipment, the floor height can be lowered, and management costs are lower, so initial costs and running costs can be reduced.
