The opening 16 is provided between the parking spaces 12 in which the entrance / exit sides 18 of the vehicle are opposite to each other as shown as an example for the purpose of daylighting and ventilation. The opening 16 in the figure is sandwiched between the parking spaces 12a and 12b. In both the parking spaces 12a and 12b, the car stop 14 is on the opening 16 side, and the car entrance / exit side 18 is at the position farthest from the opening 16. Such an opening 16 is provided on an upper floor excluding the lowermost floor of the multi-storey car park.

The vehicle fall protection structure 10 of the present invention mainly comprises a fence 20 and a steel frame horizontal member 30.
The fence 20 is a versatile mesh fence having a predetermined strength, and is mounted around the opening 16, in other words, on the parking space between the opening 16 and the bollard 14. In the specific structure of the fence 20, columns extending in the vertical direction from the floor surface are arranged on the floor surface at predetermined intervals, and a net-like fence main body is attached to the columns using fixing brackets.
According to such a fence 20, the parking space 12 and the opening 16 are partitioned so that the driver can recognize the rear position of the parking space 12 when parking. In addition, it is possible to restrict the entry of people from the parking space 12 to the opening 16.

The steel frame horizontal member 30 is a shaped steel that is horizontally laid between the beams 17 on the side surface of the opening 16. A plurality of the steel frame horizontal members 30 of the present invention are horizontally laid between the beams 17 on the side surface of the opening 16 at predetermined intervals. For the connection between the steel frame horizontal member 30 and the beam 17, a fastening means such as a fastening bolt is used between the beams 17 below (several tens of centimeters) from the floor surface of the parking space 12. The predetermined interval between the steel frame horizontal members 30 may be any interval as long as the vehicle does not fall downward from the opening 16. Further, the steel frame horizontal member 30 may have enough strength to withstand the weight of at least a car (ordinary passenger car). For example, the predetermined distance between the steel frame cross members 30 may be at least a length smaller than the total width of the car, and is preferably 1/2 or less of the tread (distance between the centers of the left and right tire contact patches) of the car. good. As a result, it is possible to reliably protect the vehicle body from falling downward only by removing the wheel from between the steel frame horizontal members 30.
