Abstract

PURPOSE:To relieve the wind loads of a floating body, a high building, and a middle building by disposing a floating body type high building to a central part, disposing a plurality of middle buildings on the windward side thereof, and disposing a plurality of low buildings on the windward sides thereof. CONSTITUTION:A high building 1 is moored on the sea by means of a floating body 5. A floating body type middle building 2 lower than the high building 1 and a floating body type low building 2' lower than the middle building are disposed, in order named, in a manner to surround the high building 1. A nozzle 3 and a slope 4 to deflect a leeward wind direction to above are located to the upper end on the windward side of each of the middle building 2 and the low building 2'. After wind collided with the low building 2' and the middle building 2 is raised along the slope 4 of the front of each building, the air is blown up in an upward direction as a speed is increased through nozzle 3 structure located to the upper part of the middle building 2. By means of wind in an upward direction, strong wind in a horizontal direction thereabove is weakened, and a wind pressure collided with the high building is relieved.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a group of floating floating city buildings.

[Conventional technology]

Traditionally, in maritime cities, various buildings have been constructed on reclaimed land on the sea surface, as shown in the perspective view of Figure 7. In this case, the buildings are constructed on artificial ground, so they require special construction, just like on land. No measures were taken to deal with wind loads. However, in floating cities, buildings are constructed on floating bodies floating on the sea surface, so the floating bodies and buildings are shaken by wind loads, which has a significant impact on safety.

Therefore, as a countermeasure, as shown in the perspective view of Figure 8,
It has also been proposed that high-rise buildings be built around the windward side of a seaside city, and by having these high-rise buildings absorb the pressure load from strong winds, the sea surface on the leeward side can be made into a calm area free from strong winds.

[Problem to be solved by the invention]

However, 2. Even in this case, the design conditions for floating buildings in the calm leeward area are reduced, but the design conditions for floating buildings in the surrounding high-rise buildings are based on direct exposure to strong winds, and the mooring equipment and floating structure are on a huge scale. It has no choice but to become a thing.

The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide a group of floating floating city buildings that can reduce pressure loads on floating bodies, high-rise hills, and mid-rise buildings.

[Means to solve the problem]

To this end, the present invention provides a floating floating city in which a floating high-rise building is disposed in the center, a plurality of floating mid-rise buildings are disposed on the windward side of the floating high-rise building, and the floating mid-rise building It is characterized by the construction of multiple floating low-rise buildings on the windward side.

[Effect]

According to such a configuration, the wind load on a high-rise building, where the wind pressure area is large and the pressure load is large, is reduced by sharing the load with the middle- and low-rise buildings.

By blowing updrafts caused by the wind hitting a mid- to low-rise building or the inclination of the building's wind pressure surface upwards using a nozzle or inclined plate installed on the top of the building, the direction of the wind toward the high-rise building is changed or disturbed. Reduce wind loads on buildings.

〔Example〕

An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a side view thereof, Fig. 2 is a plan view of Fig. 1, Fig. 3 is a vertical sectional view showing a part of Fig. 1, and Fig. 4 is the plan view of Figure 3,
This figure is a side view showing a modification of FIG. 1, and FIG. 6 is a plan view of FIG. 5.

First, in Figures 1 and 2, 1 is a high-rise building built on a floating body 5, and the floating body 5 is moored on the sea with a plurality of mooring ropes 6. Various mooring methods are used depending on conditions such as water depth. A method is selected.

2 is a floating mid-rise building that is lower than the Takaishi Building 1; 2' is a floating low-rise building that is lower than the mid-rise building 2; the multiple mid-rise buildings 2 are arranged so as to surround the high-rise building 1;
' is arranged so as to surround a plurality of mid-rise buildings 2.

Here, medium-rise building 2. As shown in FIGS. 3 and 4, a nozzle 3 and an inclined surface 4 for deflecting the downstream wind direction upward are attached to the upper end of the low-rise building 2' on the windward side.

Depending on the installation location of the floating ocean city, the direction in which strong winds will blow can be determined based on meteorological data, so when planning a maritime city, it is necessary to surround the high-rise building 1 in the direction of strong pressure as shown in Figures 1 and 2. Multiple mid-rise buildings such as 2. Multiple low-rise buildings 2'
Place.

This means that the entire surface of the high-rise building 1 is shielded from strong winds, and the wind pressure is dispersed by the multiple floating buildings.

In addition, the wind hitting the low-rise building 2' and the medium-rise building 2 rises along the slope 4 in front of the building, and then is further directed upward by a 3-meter nozzle or plate structure installed at the top of the medium-rise building 2. Increases speed and blows up.

This upward wind weakens the strong horizontal wind above it, reducing the wind pressure hitting the skyscrapers.

The floating buildings shown in Figures 1 and 2 are arranged on the sea in a U-shape as shown in Figures 5-6, and the area surrounded by these floating buildings in a U-shape is designed to provide internal peace and quiet. A relatively low-rise floating building can also be placed here at sea level.

According to this arrangement of floating buildings, taller buildings are placed in the center and lower mid-rise buildings are placed on the outside, which greatly reduces the pressure load on high-rise buildings by distributing wind loads among multiple floating buildings. be able to.

In addition, by blowing the wind that hits the low-rise floating building adjacent to the windward side of the high-rise floating building upward using a nozzle or the like, the wind load on the leeward-side high-rise floating building can be reduced.

〔Effect of the invention〕

In short, according to the present invention, in a floating floating city, a floating high-rise building is arranged in the center, a plurality of floating mid-rise buildings are arranged on the windward side of the floating high-rise building, and By arranging a plurality of floating low-rise buildings on the windward side of the building, a group of floating floating city buildings can be obtained that can reduce the pressure loads of floating bodies, high-rise buildings, and mid-rise buildings.
The present invention is extremely useful industrially.
