Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a helipad installed above a building.

[Prior art]

A heliport is considered a type of airfield, and a helipad also has a restricted airspace for aircraft approach, departure, and waiting turns, and is required to have no obstacles above it, in principle. Therefore, installing it on the ground requires a large open area with no tall buildings nearby, which places restrictions on location.

Therefore, in urban areas, helipads are installed on the rooftops of tall buildings to meet these location requirements.
Ensure that surrounding buildings do not become obstacles.

[Problems to be solved by this invention]

With a helipad on the roof of a building like this, there is a problem with airflow. In other words, the area around the building has a large disturbance in the natural wind, and the height direction is generally affected up to the same height range as the building height. Particularly near the rooftop, an upward air current is generated upward from the windward wall surface, and a swirling downward air current is generated near the leeward wall surface. This phenomenon becomes more pronounced as the building elevation increases relative to the wind direction and as the building height increases.
Therefore, it becomes a strong current with rising and descending air currents.

On the other hand, the helicopter approaches the helipad diagonally above and takes off diagonally above, so the helicopter crosses the rising and descending air currents that are occurring above the building wall, creating an extremely unstable situation. Become. Therefore, when the wind is strong, it becomes impossible to fly, leading to a decline in utilization. Additionally, natural winds tend to be stronger at higher altitudes, making it difficult to use the rooftops of tall buildings as helipads.

This invention was made to solve the above-mentioned problems, and aims to provide a highly safe helipad that can effectively utilize space within the limits of location in urban areas.

[Means for Solving the Problems] The helipad according to the present invention has a hollow cylindrical column vertically penetrating the inside of the building, which stands higher than the roof of the building, and has a hollow cylindrical column vertically penetrating the inside of the building. A take-off and landing strip was installed in the pillar, and stairs or elevators were housed in the hollow part of the pillar.

[Effect]

The takeoff and landing strips are mounted on pillars that stand on top of buildings, so they are less susceptible to the effects of wind traveling along the building walls.

By making the pillar part cylindrical, the amount of wind flowing up through the pillar part can be reduced.

The elevator can be housed in the hollow part and the pillar part can be used effectively.

〔Example〕

Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings.

In the figure, 1 is a building, which is built on deep piles 2. Four pillars 3 are formed vertically penetrating the center of the building 1. The column 3 has a hollow cylindrical shape and stands higher than the roof of the building 1. Column section 3 is formed from RC or S structure using the same foundation as building 1.

A takeoff and landing strip 4 is placed on the pillar portion 3. The take-off and landing strip 4 is constructed by forming the pillars 3 to the top, assembling them on the ground or on a rooftop, and then lifting them up along the pillars 3 and placing them there. In FIG. 1, a substantially circular takeoff and landing strip 4 is placed on four pillars 3, and adjacent takeoff and landing strips 4 are continuous.

Alternatively, as shown in FIG. 3, a takeoff and landing strip 4 may be placed on each of the three pillars 3, or two or one takeoff and landing strip 4 may be placed on each of the three pillars 3 as shown in FIGS. 4 and 5. It may be something you have done.

The hollow part 5 of the column part 3 is partitioned into left and right sides, and an elevator 6 is housed in one side so that it can be raised and lowered.
A staircase 7 is provided on the other side.

A slab 8 for a waiting area is formed below the takeoff and landing strip 4, and it is possible to climb up to a boarding ramp 9 provided on the top of the takeoff and landing strip 4.

〔Effect of the invention〕

The present invention has the above configuration and can obtain the following effects.

○B Since the takeoff and landing strip will be placed on pillars that stand above the building, it will not be affected by the airflow that rises along the building's walls, making safe takeoff and landing possible.

○B In addition, there is little wind that rises along the pillars, and even if it does rise, it is blocked by the takeoff and landing strip and has almost no effect on the takeoff and landing strip.

In particular, by making the pillar part cylindrical, the amount of wind that rises along the pillar part is further reduced.

○C The takeoff and landing strip will be placed on pillars that stand above the buildings, so the takeoff and landing strip will be located at a sufficient height and will not be restricted by surrounding buildings.

○D By storing the elevator in the hollow space within the column, the column can be used effectively.
