Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building constructed on a sloping ground by cutting a slope.

[0002]

2. Description of the Related Art Hillsides have the potential to become excellent residential areas by taking advantage of the characteristics of slopes, which have excellent views and can fully enjoy light and wind. Therefore, even in Japan with many slopes, buildings are being built on slopes,
FIG. 3 and FIG. 4 show an example of the construction of a high-rise building 2 on a steep slope 1 in order to effectively use the land.
First, the lower part of the steep slope 1 is cut, the slope is cut, and a suitable embankment is formed to form a flat land 3 which is a medium-to-high-rise building 2, for example, a six-story slope. The side constructs a one-sided corridor. In the figure, reference numeral 1a shows an existing slope before cutting.

[0003] As a countermeasure against the collapse of the steeply sloping land 1, in order to reduce the occurrence factor of the slope collapse and stabilize the slope, a method frame work 14 is provided on the steeply sloping land 1 as a restraint to prevent a landslide before it occurs. The slope builder 14 lays a concrete frame 14a on the slope in a grid pattern, and fills the frame 14a with stones to protect the slope. The goal is to minimize the deformation of the mountain.

[0004] Further, as a deterrent work for stabilizing the slope by installing a structure against the landslide force, concrete is poured into the lower part of the remaining slope after cutting, or concrete blocks are piled up. Then build the retaining wall 15.

[0005] In order to construct the building 2 on the steep slope 1 in this way, a cut is made on the slope, and in order to prevent the slope from being collapsed due to the cut, a slope stabilization measure such as a restraint and a restraint is further required. I am giving.

[0006]

However, in Japan, which has many slopes, there are few areas where resources are being effectively used, and the recent occurrence of disasters due to landslides has been caused by steep terrain. Under meteorological conditions with a lot of rainfall, only slope stabilization measures such as the above-mentioned suppression works and deterrent works were performed. It indicates that it is difficult to achieve sufficient safety.

An object of the present invention is to eliminate the disadvantages of the prior art, and to construct a building on a sloping land by cutting the sloping ground, while maintaining the safety of the building while coexisting with nature against the collapse of the sloping surface. It is an object of the present invention to provide a building which can secure the property and can flexibly cope with any terrain.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention firstly provides a building constructed on a sloping land by cutting the sloping ground and constructing the building on a sloping surface side of the building. Building the earth pressure wall apart from the building body up to the height position of the stable slope expected after the surface collapse, connecting the building body and the earth pressure wall with a connecting member; The height is
The gist is to provide at least the height of the stable slope expected after the collapse of the slope.

Third, the connecting member is composed of a horizontal beam supporting the earth pressure wall and a jumping beam transmitting the earth pressure from the horizontal beam to the building main body. The fifth point is to provide a bearing wall that resists seismic force, and fifthly, to construct an underground structure that prevents slipping and falling due to earth pressure in the basement between the building body and the earth pressure wall. .

Sixth, the horizontal beam and the jump beam constitute a part of an external corridor or an aerial corridor to be constructed between the building body and the earth pressure wall. Seventh, the bearing wall is a door boundary of the building body. Eighth, the subject matter is that the underground structure is a facility such as an aquarium, a warehouse, and a parking lot.

According to the first to fifth aspects of the present invention, when the slope is collapsed, the earth pressure wall is separated from the building body up to the height position of the stable slope predicted after the collapse of the slope, and the earth pressure wall is previously formed. Since it is constructed, the landslides that accumulate are deposited along the earth pressure wall, and the safety of the building can be ensured without the need to provide a restraint on the inclined surface as in the past. Then, the earth pressure received by the earth pressure wall is transmitted to the building body by beams, particularly, horizontal beams and jump beams.

Further, in the building body, the earth pressure and the seismic force are received by the bearing wall and the underground structure. Therefore, the earth pressure from the slope is received by the total weight of the earth pressure wall and the building main body integrally, and the slope is stabilized. In addition, since the earth pressure wall is integrated with the building body, a feeling of pressure on the surrounding natural environment can be reduced.

Further, since the building main body and the earth pressure wall are constructed separately from each other, it is possible to prevent moisture of cliff from being transmitted into the house of the building main body.

According to the sixth aspect of the present invention, in addition to the above function, the horizontal beam and the jump beam form part of an external corridor or an aerial corridor constructed between the building body and the earth pressure wall. In addition, the transmission member for transmitting the earth pressure from the earth pressure wall to the building main body can also be used as a component member of the aerial corridor, and this need not be provided separately. Further, since a space is formed between the building main body and the inclined surface by an external corridor or an aerial corridor, safety is enhanced.

According to the seventh aspect of the present invention, in addition to the above-mentioned operation, the bearing wall is a door boundary wall of the building body, so that a member for receiving the earth pressure from the earth pressure wall is not separately provided. Not only will the living space not be narrowed, but also the bearing wall will be composed of thick pillars and thick walls, so that a living environment with excellent heat insulation and sound insulation can be formed, and if the living comfort improves, At the same time, the strength of the building itself is improved.

According to the present invention, in addition to the above-mentioned functions, the underground structure supporting the earth pressure wall and the building body is a facility such as a water tank, a warehouse, a parking lot, etc. Can be used effectively.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a vertical sectional side view showing an embodiment of a building of the present invention, and FIG.
The same components as those of the conventional example shown in FIGS. 3 and 4 are denoted by the same reference numerals. In the same manner as in the prior art of the present invention, a steep slope 1 is cut and the slope is scraped off to form a flat land 3 which is a middle and high-rise building 2, for example, a six-story building with a one-sided corridor on the slope side. Build a residential building.

In the present invention, the earth pressure wall 4 is constructed as a retaining wall perpendicular to the boundary between the land 3 formed by cutting and the slope. When the slope is collapsed, the height of the earth pressure wall 4 is set as a stable slope 1b which is capable of receiving the anticipated collapsed soil due to the accumulation of sediment which falls naturally, and which is naturally formed after the collapse. Set to the expected height.

The earth pressure wall 4 is formed in a plane arc shape so that the impact earth pressure at the time of collapse escapes to the end as shown in FIG. 2, but the invention is not limited to this. As a form, it may be formed in a bent shape or a straight shape having an appropriate corner so as to receive the earth pressure.

The earth pressure wall 4 is provided between the main body of the building 2 and a horizontal beam 5 in contact with and in parallel with the earth pressure wall 4, and the horizontal beam 5 and the main body of the building 2 are connected to each other by the horizontal beam 5. And a plurality of jump beams 6 provided at appropriate intervals at right angles to each other. Thereby, the horizontal beam 5
And the jump beam 6 reinforce the earth pressure wall 4. In this case, horizontal beam 5
The jumping beam 6 serves as a component of the aerial corridor 7 provided between the earth pressure wall 4 and the main body of the building 2, and also serves as a member for transmitting earth pressure from the earth pressure wall 4 to the main body of the building 2.

The horizontal beam 5 may form an external corridor 16 and the aerial corridor 7 is formed as an external corridor 16 if it has no roof or ceiling.

The main body of the building 2 is provided with a bearing wall 8 formed by a door wall. The load-bearing wall 8 is composed of a thick column and a thick wall for receiving earth pressure and seismic force from the horizontal beam 5 and the jump beam 6.

Further, as a foundation structure for more firmly supporting the main body of the building 2 and the earth pressure wall 4, slipping or falling due to earth pressure may be provided in the basement between the main body of the building 2 and the earth pressure wall 4. Of the underground structure 9 for preventing the occurrence of the
And are integrated with this. The underground structure 9 is configured so that it can always be used for a water tank, a warehouse, a parking lot, and the like. Further, the underground structure 9 can be used as a basement for housing use.

The underground structure 9 is provided when the impact earth pressure is large and a passive earth pressure is required. This can be omitted.

Further, although not shown, a water collecting device is provided on the inclined surface to stabilize the inclined surface. In this case, the water collecting device is usually formed as a dry river and a landscape garden is formed as a dry river.In a season with heavy rainfall, the garden becomes a stream and cleans the water, forming a garden that becomes a pond. Landscaping is good.

As described above, most of the earth pressure from the inclined surface is always supported by the earth pressure wall 4. The present invention is based on the premise that the slope will eventually collapse,
When the slope is collapsed due to an earthquake or rainfall, the falling soil is actively guided to the earth pressure wall 4 and deposited and received along the wall. In this case, since the earth pressure wall 4 has been constructed in advance to the height position of the stable slope which is predicted after the slope collapse, there is a possibility that the earth collapses and the earth and sand flows over the earth pressure wall 4 and flows into the building 2 side. Absent.

Part of the earth pressure applied to the earth pressure wall 4 escapes in the direction of the end of the earth pressure wall 4 along the arc-shaped earth pressure wall 4, and the earth pressure is uniformly applied to each part. Then, the beam is further transmitted to the main body side of the building 2 by the horizontal beams 5 and the jump beams 6 in the aerial corridor 7 and supported by the load-bearing walls 8.

The earth pressure from the earth pressure wall 4 is applied to the underground structure 9.
To prevent the body 2 of the building 2 from sliding or falling down from the impact earth pressure.

In this way, the earth pressure on the inclined surface is reduced
The earth pressure wall 4 and the main body of the building 2 are integrally formed by the bearing wall 8 and the underground structure 9 having the thick columns and the thick walls on the side of the main body of the building 2 via the horizontal beams 5 and the jump beams 6 of FIG. The overall weight is taken to stabilize the slope.

The total weight can be changed by changing the height of the main body of the building 2, and the stress increases by increasing the area. It can be balanced and can handle any terrain slope.

[0031]

As described above, in the building according to the present invention, when the slope is cut and the building is constructed here, the earth pressure wall and the building body are integrated to reduce the earth pressure on the slope. As a result, the slope was stabilized by suppressing the pressure with the total weight of the building, so that the landscape of the satoyama that became a part of the inhabitants' daily life and became familiar to us every day was not greatly destroyed, It can ensure the safety of buildings while coexisting with nature, and can flexibly cope with any terrain.
