(Reason for disclosure 2) The Japan Iron and Steel Federation Architectural Steel Structure Research Network Kansai Region Sub-Network held the 2019 Japan Iron and Steel Federation Kansai Region “Architecture Department Field Study” on September 26, 2019. , published the invention.

The present invention relates to a building whose outer periphery is made up of a single external frame with multiple layers, and whose interior is made up of a single layer and a single internal frame.

As a conventional building, the outer periphery is composed of a reinforced concrete frame with multiple layers, which bears the majority of the earthquake force, and the interior is composed of a single layer with a single steel frame, which absorbs the majority of the earthquake force. A structure in which seismic resistance elements are minimized is known (see, for example, Patent Document 1). In such a building, there is a first floor on which the beams of the external frame are present, and a second floor between the first floors. Therefore, since the reinforced concrete beams of the external frame are concentrated on the first floor, a light space is realized on the second floor with as few large beam-shaped protrusions as possible.

Patent No. 3120105

In the building of Patent Document 1, the outer end of the first floor is connected to and supported by reinforced concrete beams in the external frame, while the outer end of the second floor is supported by the upper and lower reinforced concrete beams in the external frame. It is connected to and supported by a steel column-beam frame installed between the beams. Therefore, there will be multiple columns on the first floor to support the second floor above it, creating a large interior space with almost no columns in the space above the first floor. It was difficult to do so.
In addition, if an atrium space is provided inside the external frame that connects the space on the first floor and the space on the second floor, the second floor on the upper floor side located in the space on the first floor will be supported. The plurality of pillars for this purpose are a factor that impedes visibility and ease of access to the above-mentioned atrium space. Therefore, there have been cases where it has not been possible to sufficiently promote communication between users on the upper and lower floors via the atrium space.

In view of this situation, the main problem of the present invention is that in a building where the outer periphery is composed of multiple layers and one external frame, and the inside is composed of one layer and one internal frame, there are beams of the external frame. It is possible to realize a large indoor space with almost no columns on the first floor, and when an atrium is provided inside the building, communication between users on the upper and lower floors can be promoted through the atrium. The point is to provide technology.

A first characteristic configuration of the present invention is a building in which the outer peripheral part is composed of a plurality of layers and one external frame, and the inside is composed of one layer and one internal frame,
A second floor between the first floors where the beams of the external frame are present is provided in a state extending outward from the internal column of the internal frame,
A suspension support part is provided that suspends and supports the second floor from the first floor on the upper floor side ,
The frame body surrounding the hanging support part is formed in a flat rectangular shape along the outer edge of the second floor in plan view .

According to this configuration, the second floor, which is provided between the first floors where the beams of the external frame exist, extends outward from the internal columns of the internal frame, and the outer end thereof is connected to the beam of the external frame. It is suspended and supported by the suspension support section from the connected and supported first floor on the upper floor side. With this, on the first floor on the lower floor side of the second floor that is suspended and supported by the suspension support part, the pillars for supporting the second floor can be omitted or simplified. It is possible to construct a large indoor space with almost no pillars on the floor.
In addition, if an atrium space is provided inside the external frame that connects the space on the first floor and the space on the second floor, it is necessary to support the second floor on the upper floor side on the first floor. Since the columns can be omitted or simplified, visibility and ease of access to the atrium space can be ensured.
Therefore, according to the present invention, in a building where the outer periphery is made up of multiple layers and one external frame, and the inside is made up of one layer and one internal frame, the beams of the external frame are placed on the first floor. To provide a technology that makes it possible to realize a large indoor space with almost no pillars, and to promote communication between users on the upper and lower floors via the atrium space when an atrium space is provided inside a building. I can do it.
Furthermore, according to this configuration, the frame surrounding the suspension support part that suspends and supports the second floor from the first floor on the upper floor side is formed into a flat rectangular shape along the outer edge of the second floor in plan view. Therefore, it is possible to reduce the protruding width of the frame in the space on the second floor and realize a space as wide as possible.

A second characteristic configuration of the present invention is an inner atrium space vertically penetrating the first floor of multiple layers;
an outer atrium space formed between the outer edge of the second floor and the external frame between the pair of upper and lower first floors;
The suspension support part is arranged to suspend and support an outer edge of the second floor ,
The inner atrium space is provided with an escalator or stairs for going back and forth between the upper and lower first floors, skipping the second floor .

According to this configuration, a relatively large inner atrium space that vertically penetrates the first floor of the plurality of layers can be formed inside the building as a space surrounded by a plurality of internal pillars that constitute an internal frame, for example. . This inner atrium space facilitates the movement and communication of users between the spaces on the first floor of multiple layers.
On the other hand, since the outer edge of the second floor is suspended and supported from the first floor on the upper floor side by the suspension support part, the outer edge of the second floor is separated from the external frame and spaced inward. In this manner, an outer atrium space can be formed between the outer edge of the second floor and the external frame between the pair of upper and lower first floors. In the space above the first floor on the lower floor side, columns for supporting the second floor on the upper floor side can be omitted or simplified to ensure visibility and ease of access to the outer atrium space. Therefore, it is possible to promote user communication between the space on the first floor and the space on the second floor via the outer atrium space.

A third feature of the present invention is that the beam size of the second floor is set smaller than the beam size of the first floor.

According to this configuration, since the second floor is suspended and supported from the first floor on the upper floor side by the suspension support part, the beam size of the second floor can be set smaller than the beam size of the first floor. can. As a result, in the space on the lower floor side of the second floor, a light and airy space can be realized in which the large beam-shaped protrusion is further suppressed.

A fourth feature of the present invention is that rail portions of the fire shutter are provided on both sides of the frame.

According to this configuration , the rail portions of the fire shutter are arranged on both sides of the frame surrounding the hanging support, and the frame can be effectively used as a wall for forming a fireproof partition.

A fifth characteristic configuration of the present invention is that air conditioning equipment for the spaces above and below the second floor is installed inside the floors of the first floors above and below.

According to this configuration, an air conditioner is installed inside the floor of the first floor, and the space on the first floor and the space on the second floor can be air-conditioned by the air conditioner. With this, there is no need to install the air conditioning equipment inside the floor of the second floor, so the thickness can be suppressed as much as possible and the height of the vertical space can be gained.

Embodiments of a building according to the present invention will be described based on the drawings.
The building of this embodiment (hereinafter referred to as the "main building") has an RC (reinforced concrete) external frame 1 (see Fig. 1) on its outer periphery, which bears the majority of the earthquake force, and an internal structure of S The building is constructed with a (steel) internal frame 2 (see Figure 2) to minimize earthquake-resistant elements.

Further, the external frame 1 has a structure with two layers (an example of multiple layers) and one frame, while the internal frame 2 has a structure with one layer and one frame.
That is, the external frame 1 is constructed as a structure in which reinforced concrete beams 1A are provided at a pitch of two stories with respect to a plurality of reinforced concrete columns 1B arranged along the outer periphery of the internal frame 2.
On the other hand, in the internal frame 2, steel beams 11a and 12a supporting the floors 11 and 12 of each level are arranged outward from a plurality of internal steel columns 2B (an example of internal columns) arranged approximately at the center in a plan view. It is constructed as a structure that overhangs the roof.

With this configuration, as shown in FIG. 2, the floors 11 and 12 of each level built on the internal frame 2 include the first floor 11 where the reinforced concrete beam 1A of the external frame 1 exists on the outside, and the first floor 11 on the outside where the reinforced concrete beam 1A of the external frame 1 exists. On the other hand, the second floor 12 where the reinforced concrete beam 1A of the external frame 1 does not exist are arranged alternately. For example, in this building, the 1st, 3rd, 5th, and 7th floors are the first floor 11 where the reinforced concrete beam 1A of the external frame 1 exists on the outside, and the other 2nd, 4th, and 6th floors are The eighth floor is the second floor 12 where the reinforced concrete beam 1A of the external frame 1 does not exist on the outside.

That is, in the external frame 1, the reinforced concrete beams 1A to which the ends of the floor 11 are connected are concentrated on the outside of the first floor 11, while on the outside of the second floor 12, for example, Since only a very small connecting steel beam 1C that can connect the ends of the floor 12 is provided, a light space is realized inside the connecting steel beam 1C.

As shown in FIG. 2, approximately at the center of the internal frame 2 in a plan view, there is an internal atrium space 22 that vertically penetrates the floors 11 and 12 configured in each level. It is formed as a space surrounded by internal steel columns 2B. As shown in FIG. 3, the floors 11 and 12 of each level and the steel beams 11a and 12a that support them are provided so as to extend outward from the plurality of internal steel columns 2B.

The inner atrium space 22 facilitates the movement and communication of users between the indoor spaces 11S on the first floor 11 of multiple layers. Escalators 25, stairs 26, etc. are provided for coming and going. Incidentally, the stairs, elevators, etc. for going to and from each floor including the first floor 11 and the second floor 12 are also arranged, for example, on the front side or the back side in the depth direction of FIG. 2, although they are not shown. .

Since no wall or the like is provided to block the view at the boundary between the indoor spaces 11S and 12S on the floors 11 and 12 of each floor and the inner atrium space 22, the indoor spaces 11S and 12S of each floor are It becomes a large space connected by an inner atrium space 22. Therefore, a "see-be-seen" relationship is created on a daily basis between the users in each space 11S, 12S, 22 through the inner atrium space 22, and a layout that naturally creates interaction is realized. There is.

As shown in FIGS. 3 and 4, in some specific second floors 12A of the second floors 12 described above, the specific second floors 12A are suspended and supported from the first floor 11 on the upper floor side. A hanging support section 30 is provided. Specifically, the outer edge 12b of the specific second floor 12A is located at a location spaced further inward than the external frame 1, and the suspension support section 30 suspends and supports the outer edge 12b of the specific second floor 12A. It is arranged so that
On the other hand, the outer ends of the second floors 12 other than the specific second floor 12A extend to and connect to the connecting steel beam 1C provided between the upper and lower reinforced concrete beams 1A in the external frame 1.

For example, in this building, in FIG. 2, the second floor 12 on the right side of the fourth floor, the second floor 12 on the left side of the sixth floor, and the second floor 12 on the right side of the eighth floor are the specific second floor 12A. The outer edge 12b is suspended and supported by a plurality of hanging supports 30 arranged along the outer edge 12b in a state that it hangs down from the first floor 11 on the upper floor side. With this configuration, the first floor 11 on the lower floor side of the specific second floor 12A suspended and supported by the suspension support part 30 does not require a pillar to support the specific second floor 12A. A large indoor space 11S is constructed on the first floor 11 without any columns.
In this embodiment, by suspending and supporting the specific second floor 12A only by the suspension support part 30, a pillar for supporting the specific second floor 12A can be installed on the first floor 11 on the lower floor side. Although a configuration in which no columns are provided is adopted, it is also possible to provide some columns on the first floor 11 and configure the specific second floor 12A to be supported by both the columns and the suspension support section 30. do not have. Even in such a case, the columns for supporting the specific second floor 12A on the first floor 11 can be simplified.

As shown in FIG. 3, the outer edge 12b of the specific second floor 12A is suspended and supported by the suspension support part 30, and is located at a location spaced further inward than the external frame 1. Therefore, between the pair of upper and lower first floors 11 that vertically sandwich this specific second floor 12A, an outer atrium space 21 is formed between the outer edge 12b of the specific second floor 12A and the external frame 1. has been done. In the indoor space 11S on the first floor 11 on the lower floor side leading to the outer atrium space 21, as shown in FIGS. There is no columnar shape. Therefore, communication between users between the indoor space 12S on the specific second floor 12A and the indoor space 11S on the first floor 11 on the lower floor side via the outer atrium space 21 is promoted. Become.

Since no wall or the like is provided to block the view at the boundary between the upper and lower indoor spaces 11S, 12S and the outer atrium space 21 of the specific second floor 12A, the upper and lower floors of the specific second floor 12A are The indoor spaces 11S and 12S are a large space connected by an outer atrium space 21.
Therefore, a "see-be-seen" relationship is created on a daily basis between the users in each space 11S, 12S, and 21 through the outer atrium space 21, and a layout that naturally creates interaction is realized. There is.

This building is a school building, with the design of the external frame 1 as described above (see Figure 1) and the state of the interior spaces 11S and 12S on the first floor 11 and the second floor as described above (see Figure 3). It can be suitably applied as For example, in the indoor space 12S on the second floor 12 including the specific second floor 12A, a plurality of relatively small rooms such as a laboratory can be provided. On the other hand, the indoor space 11S on the first floor 11, including the lower floor side of the specific second floor 12A, has fewer pillars, so a relatively large room such as an exercise room or a lecture room can be provided therein.

As shown in FIG. 3, a steel beam 11a extends outward from the internal steel column 2B to support the first floor 11, and a steel beam 11a extends outward from the internal steel column 2B to support the second floor 12. When comparing the beam thickness of the steel beam 12a that supports the second floor 12, the beam thickness of the steel beam 12a that supports the second floor 12 is set smaller than that of the steel beam 11a that supports the first floor 11. That is, since the specific second floor 12A is suspended and supported from the first floor 11 on the upper floor side by the suspension support part 30, the beams of the steel beams 12a that support the second floor 12 including this specific second floor 12A are The beam size can be set smaller than the beam size of the steel beam 11a that supports the first floor 11. With this configuration, the indoor space 11S on the first floor 11 on the lower floor side of the specific second floor 12A can be constructed as a light space in which large beam-shaped protrusions are further suppressed. can.

Furthermore, since the steel beam 11a supporting the first floor 11 has a relatively large beam size, a relatively large intra-floor space 11b (an example of the interior of the floor) is formed inside the floor of the first floor 11. Therefore, air conditioning equipment 50 for the indoor spaces 11S and 12S above and below the first floor 11 is provided in this intra-floor space 11b. The indoor space 11S on the first floor 11 is air-conditioned by an air conditioner 50 provided in the intra-floor space 11b of the first floor 11 below the floor. On the other hand, the indoor space 12S on the second floor 12 is air-conditioned by an air conditioner 50 provided in the intra-floor space 11b of the first floor 11 behind the ceiling. That is, the air conditioner 50 is configured to supply conditioned air to the indoor spaces 11S and 12S above and below the first floor 11 on which it is installed. In addition, although not shown in the drawings, locations for blowing out conditioned air to the indoor spaces 11S and 12S are arranged so as to form an air barrier at the boundary with the outer atrium space 21 and the inner atrium space 22. Deterioration of efficiency can be suppressed.
In this way, the air conditioning equipment 50 installed in the floor space 11b of the first floor 11 air-conditions the indoor spaces 11S and 12S above and below the first floor 11, so the air conditioning equipment 50 is installed inside the second floor 12. installation is not required. As a result, the thickness of the second floor 12 is suppressed as much as possible, and the height of the interior spaces 11S and 12S above and below it is maximized.

As shown in FIGS. 3 and 4, the hanging support part 30 is surrounded by a frame 31 formed in a flat rectangular shape along the outer edge 12b of the specific second floor 12A in plan view. Rail portions 36 of the fire shutter 35 are provided on both sides of the frame 31. That is, in the indoor space 12S on the specific second floor 12A, the protruding width of the flat rectangular frame 31 in plan view is reduced, and a space as wide as possible is realized. Furthermore, the frame body 31 is effectively used as a wall for forming a fireproof partition, and on both sides thereof there are fireproof shutters that are closed in the event of a fire to partition the specific second floor 12A and the outer atrium space 21. Thirty-five rail sections 36 are arranged.
