Description

The present invention relates to a combined structure of a plurality of relatively small buildings that can be combined and used integrally.

In a general industrialized house, processing in a factory is performed by comprehensively systemizing structural frame, outer wall, inner wall, roof and other constituent members, panels, frames, units, etc. based on a predetermined design module. We are working to improve accuracy, improve the efficiency of on-site assembly work, and reduce construction costs. Therefore, in this type of industrialized house, it is difficult to partially modify the floor plan, quadrature meter, fit of details, etc. at a finer level than the design module according to the individual site conditions. ..

Therefore, for example, when constructing a unit-type industrialized house on a site with a height difference, the height of the top of the foundation is made constant by creating the ground or designing the foundation individually, or the height difference of the site is adjusted. It is necessary to take measures such as separately preparing and installing a structure for semi-underground (for example, Patent Document 1 etc.). On the other hand, when building a skip-floor building on a flat site, it is necessary to prepare a structure for half a floor according to the skip height of the floor and combine it in the right place (for example). , Patent Document 2 etc.).

Using the design system of industrialized houses, you can build a building whose floor height changes intricately on a site with different heights, or you can build a building with many outside corners and inside corners on a site where the site boundaries are complicated. Building a building increases the labor of structural calculation, custom processing of parts, and on-site delivery of the parts to be connected, which tends to lead to a decrease in construction efficiency and an increase in cost.

Therefore, the present invention provides a combined structure of buildings that can be efficiently constructed by using the design system of an industrialized house even on a site under such conditions.

Coupling structure of a building to which the present invention is employed to achieve the foregoing objects, the four sides are surrounded by an outer wall structure, at least two separate buildings are overlapped with each other part of the outer wall structure of each other arranged adjacent to match, the location superposition the outer wall structure, traffic between the adjacent buildings, prospects, communicating opening is provided to allow for natural lighting or ventilation, the position or size of the communicating opening Are different from each other and are characterized as having a portion of the outer wall structure of the other building exposed inside at least one of the buildings.

Further, the present invention is characterized in that, in the above-mentioned joint structure of buildings, the heights of the tops of the foundations of at least two of the buildings are different from each other.

Further, the present invention is characterized in that, in the above-mentioned joint structure of buildings, the heights of the floor surfaces of the first floor or the upper floor of at least two of the buildings are different from each other.

Further, the present invention is characterized in that, in the above-mentioned joint structure of buildings, at least two of the buildings have different construction methods .

Further, the present invention is characterized in that, in the above-mentioned building connection structure, at least two of the buildings have different vibration properties and are connected via an expansion joint.

By adopting the combined structure of the buildings of the present invention in which a plurality of independent buildings are arranged and connected adjacent to each other so as to overlap each other's outer wall structures, the floor height, floor height, floor plan, etc. of each building can be adjusted. , Can be flexibly designed without being affected by adjacent buildings. Therefore, while basically using the system of an industrialized house, it is possible to efficiently and economically realize a variable indoor space that is not bound by the design module on the system as a whole building connection. ..

The overlapping points of the outer wall structures of the adjacent buildings can be arranged in various ways by shifting the position and size of the communication openings provided in both outer wall structures and utilizing the wall thickness. It can be used. As a result, it is possible to form a unique indoor space with various textures even in an industrialized house that tends to have a uniform space composition.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 6 show a house 1 as a building combination, which adopts the building connection structure according to the present invention. The example house is built on the site 9 located in the first-class low-rise residential area and the first-class altitude district in the urban area or the suburbs of the city. The site 9 has a frontage of about 8 m, a depth of about 15 m, and an area of about 120 m ² facing the road R on the north side, and has a height difference of about 1.2 m higher from the road R side toward the back. The building coverage ratio of the site 9 defined by the city plan is 50%, the floor area ratio is 100%, and the height limit is 10 m. In the following description, when the positional relationship of each part of a house or building is shown, it is expressed in north, south, east, and west with reference to the directional symbol shown in FIG.

This house is composed of 5 independent buildings 11 to 15 large and small. Each of the five buildings 11 to 15 has a simple rectangular planar shape, and each of the four circumferences is surrounded by an outer wall structure.

Here, "independent building" means a foundation and a skeleton that can stand on its own, that is, even if an adjacent building disappears, it can survive in a structurally stable state without being affected by it. It means a building equipped. Therefore, the load distribution and vibration properties (behavior during an earthquake) in structural calculation can be basically treated as being completed only in that building. In addition, the "outer wall structure" does not simply mean the outer wall material (exterior decorative material) that appears in the exterior, but the framework or frame that constitutes the wall structure around the building as a support for the outer wall material, etc. It means a structure as a robust bearing element with a wall thickness larger than that of a general inner wall (partition wall). The outer wall material is basically stretched on the outside of the outer wall structure facing the outside, but depending on the part, an opening is provided instead of the outer wall material and fittings are installed, or most of the wall surface. May open like a piloti.

At least two of the five buildings 11 to 15 are arranged adjacent to each other so as to overlap a part of each other's outer wall structures. To the northeast of the site, the building 11 is located close to the road with its long side facing east-west. On the south side of the building 11, the building 12 having the smallest building area among the five buildings is arranged with its long side facing north-south. The outer wall structure on the north side of the building 12 is in contact with a part of the outer wall structure on the south side of the building 11, and the outer wall structure on the west side of the building 11 and the building 12 are aligned on the same surface.

On the west side of the building 11 and the building 12, the building 13 is arranged with its long side facing north-south. The outer wall structure on the east side of the building 13 is in contact with a part of the outer wall structure on the west side of the building 11 and the entire outer wall structure on the west side of the building 12, and the outer wall structure on the south side of the building 12 and the building 13 are flush with each other. Aligned on top.

On the south side of the building 12 and the building 13, the building 14 is arranged with its long side facing east-west. This building 14 has the largest building area of the five buildings, and is ^{about 24 m 2.} A part of the outer wall structure on the north side of the building 14 is in contact with all of the outer wall structures on the south side of the building 12 and the building 13, and the outer wall structures on the west side of the building 12 and the building 14 are aligned on the same plane. There is.

On the south side of the building 14, the building 15 is arranged with its long side facing east-west. The outer wall structure on the north side of the building 15 is in contact with a part of the outer wall structure on the south side of the building 14.

Each of the buildings 11 to 15 has a height of about two stories. However, as shown in FIGS. 3 to 5, the heights of the tops of the foundations (not shown) that support each of the buildings 11 to 15 differ from each other according to the height difference of the ground surface. The heights of the floors of the first and second floors of each building 11 to 15 are also different between the buildings. Further, as shown in FIG. 6, roofs are provided in each of the buildings 11 to 15, but the roof shapes of the buildings 11, 12, 13 and 15 are single-flow roofs having different slope directions from each other, and the roof shape of the building 14 is provided. Are asymmetric gable roofs (invited roofs), and their maximum heights (building heights) are also different from each other.

In this way, by constructing relatively small buildings with a simple rectangular plan shape independently of each other, the indoor space of each building can be freely designed without being affected by the relationship with the adjacent building. Will be possible. Basically, while adopting an economical design system for industrialized houses where the specifications and dimensions of the members are standardized, the standard dimensions of the quadrature meter are changed for each building, and steps are provided on the floor between the buildings. , It is possible to form a skip floor that reflects the height difference of the site as it is. On the contrary, it is also possible to arrange each building with a constant floor height on a site with a height difference. Since it is possible to individually select the construction method of each building, it is possible to make buildings with different construction methods adjacent to each other. By combining these methods, various changes and flows of space that are difficult to realize with a general industrialized house design system are created inside and outside the house.

The structural strength of the overlapping points of the outer wall structures of the adjacent buildings 11 to 15 is simply doubled. Similarly, since the heat insulating property, the soundproofing property, the shielding property, and the like are increased, the safety, comfort, comfort, and the like of the indoor space surrounded by them are also improved.

Since a plurality of buildings arranged adjacent to each other have different vibration properties, it is preferable that they are connected to each other via an expansion joint (not shown).

Communication openings that allow traffic, daylighting, ventilation, etc. between adjacent buildings are provided at the overlapping points of the outer wall structures of the adjacent buildings 11 to 15. The communication opening can take various forms depending on the site.

For example, the connecting opening 21 that connects the first floor portion of the building 14 and the first floor portion of the building 15 has the same opening height in the cross-sectional view (FIG. 4), but the opening in the plan view (FIG. 1). The widths are different, and the opening width on the building 15 side is larger than the opening width on the building 14 side. Therefore, a part of the outer wall structure on the south side of the building 14 is exposed on the building 15 side. The same outer wall material as the outer wall material stretched on the outer wall structures on the east side and the west side facing the outside of the building 14 is stretched at the exposed portion.

Further, the connecting opening 22 connecting the first floor portion of the building 12 and the first floor portion of the building 14 has an opening position and an opening width that match each other in the plan view (FIG. 1), but is a cross-sectional view (FIG. 4). ), The opening height on the building 12 side is larger than the opening height on the building 14 side. Therefore, a part of the outer wall structure on the north side of the building 14 is exposed on the building 12 side. The same outer wall material as the outer wall material stretched on the outer wall structure on the east side and the west side of the building 14 is stretched at the exposed portion.

Further, as shown in FIG. 3, the upper portion of the first floor portion of the building 14 communicates with the lower portion of the second floor portion of the building 13 via the connecting opening 23. The communication opening 23 allows light and ventilation between the first floor and the second floor, although people cannot come and go.

As shown in FIG. 7, when the positions, widths, heights, etc. of the communication openings 24 provided at the overlapping points of the outer wall structures of the adjacent buildings are shifted, the other one is on the indoor side of at least one building. A part of the outer wall structure of the building is exposed. If an outer wall material similar to that applied to the outdoor part of the building is attached to the exposed portion, the outer wall material becomes an interior element for the adjacent building. By using such a configuration, the material feeling of the outdoors is taken into the interior, and an atmosphere where the boundary between the inside and the outside is ambiguous is created, as if the indoor space and the outdoor space are fused.

Further, a deep wall storage space (not shown) can be provided in the step portion formed by shifting the communication opening 24 by utilizing the wall thickness of the outer wall structure.

At the overlapping points of the outer wall structures of the adjacent buildings, the outer wall material or the inner wall material may not be stretched on the outer wall structure of one of the buildings, and the skeleton of the outer wall structure may be exposed and finished as it is. In this case, a powerful skeleton design-like atmosphere that emphasizes the skeletal structure of the building is created in the building.

In addition, since the outer wall structure to which the outer wall material is stretched is naturally excellent in fire resistance and waterproofness, for example, such an outer wall structure may be placed in a part facing a space around water or a kitchen space. It is also preferable to partition from the living space of.

Further, for example, as shown in FIG. 7, a visible window hole-shaped communication opening 25 is provided at the overlapping portion of the outer wall structure of the building, and the communication opening 25 is used as, for example, a display shelf, a bookshelf, a TV stand, or the like. You can also use it.

As described above, according to the building structure of the present invention, the portion where the outer wall structures are doubly overlapped can be used in various modes by utilizing the wall thickness. As a result, a unique and varied living space with various textures is formed inside the building.

It should be noted that the technical scope of the present invention should not be construed in a limited manner by the illustrated embodiment, but should be conceptually construed based on the description of the scope of claims. In carrying out the present invention, the number and arrangement of buildings, the shape, number of floors, structure, floor plan of each building, etc. are appropriately modified to the extent that substantially the same effect as that of the exemplary embodiment can be obtained. Things are possible.

The present invention can be widely applied to houses and other buildings constructed by using the design system of industrialized houses.
