Description

TECHNICAL FIELD The present invention relates to a storage structure for a building arranged over a stepped portion of a site with a difference in height, and a building equipped with the structure.

Conventionally, when arranging a building across a stepped portion of a site with a height difference, a built-in garage may be installed on the low-lying side of the building (for example, Patent Documents 1 and 2). In these inventions, by incorporating the parking lot into the interior of the house, it is possible to prevent the living area of the house from being squeezed compared to the case where the parking lot is arranged outside the house.

However, if a house is placed across the stepped part of such a site with a difference in height and a built-in garage is installed on the low land side of the house, the ceiling height of the built-in garage will be unnecessarily high, and the space above the built-in garage will be wasted. There was a problem that Therefore, an invention has been proposed that enables effective use of the space above the built-in garage by forming a storage space above the built-in garage, although the site does not have a height difference (for example, Patent Document 3).

On the other hand, a building placed across a step on a site with a difference in height has a special structure compared to a building placed on a site without a difference in height, so the structural evaluation is generally complicated. Therefore, if a storage space formed integrally with the built-in garage as described in Patent Document 3 is installed above the built-in garage located on the low-lying side of the building, the structural analysis of the building will become more complicated. In addition, there is a risk of creating structural weaknesses in the building.

Therefore, the present invention has been made in view of the above-mentioned problems, and in a building arranged over a stepped part of a site with a difference in height, the upper space of a room arranged on the lowland side is effectively used as a storage space. Another object of the present invention is to provide a storage structure for a site with a difference in height, which can minimize the impact on the structure of the main body of the building, excluding the floor of the storage space .

A first storage structure for a site with a difference in elevation according to the present invention is a storage structure for a site with a difference in elevation for storing objects in a building arranged across a step portion of a site with a difference in elevation, the building comprising: In the upper part of the room located on the lowland side of the building, a storage space is provided whose ceiling surface is substantially the same height as the ceiling surface of the room located on the highland side of the building, and the floor of the storage space is , supported from below by a steel-frame frame formed independently of the beams and columns that support the main body of the building except for the floor of the storage space , and the beams and columns are It is characterized in that it is supported by a building foundation, and the steel frame frame is supported and fixed to a frame foundation dedicated to the steel frame frame .

The second storage structure for a site with a difference in elevation according to the present invention is characterized in that the room arranged on the lowland side is a built-in garage.

In the storage structure of the third height difference site of the present invention, the building consists of multiple floors, the storage space is arranged facing the landing of the staircase connecting each floor of the building, and it is possible to come and go with the staircase. It is characterized by

A first building of the present invention is characterized by comprising the storage structure for a site with height difference according to any one of the first to third .

According to the storage structure of the first height difference site of the present invention, in the upper part of the room arranged on the lowland side of the building, the ceiling surface is substantially the same height as the ceiling surface of the room arranged on the highland side of the building Since the storage space is formed, the upper space of the room arranged on the low land side can be effectively utilized as a storage space in the form of a skip floor. In addition, the floor of the storage space is supported from below by a steel-frame frame that is formed independently of the beams and columns that support the main body of the building, excluding the floor of the storage space. It is possible to minimize the impact on the structural evaluation of the building even if the storage space is installed in the building, and it is possible to avoid the occurrence of structural weaknesses in the building. Furthermore, since the steel-frame frame is supported and fixed not on the building foundation that supports the beams and columns, but on the dedicated frame foundation for the steel-frame frame, there is no need to perform construction at the same time as the beams and columns. It does not complicate the construction of materials. In addition, since the installation can be performed while monitoring the construction progress of the entire building, workability can be improved.

According to the storage structure of the second high-height site of the present invention, the room located on the low-lying side is a built-in garage that does not need to secure a high ceiling height, so the volume of the storage space is increased and efficiency is increased. It is possible to store items effectively.

According to the storage structure of the third height difference site of the present invention, the storage space is arranged facing the landing of the staircase connecting the floors of the building, and it is possible to come and go with the staircase. It is possible to shorten the movement between the room facing the front and the storage space, and it is possible to easily put in and take out stored items.

According to the first building of the present invention, since the building is equipped with the storage structure for the site with height difference according to any one of the first to third , the influence on the structure of the main body of the building is minimized. The space around the room located on the lowland side can be efficiently utilized.

Hereinafter, an embodiment of a storage structure for a site with a difference in height according to the present invention will be described with reference to each drawing. The storage structure of a site with a difference in height of the present application is a structure mainly used when a built-in garage is provided on the lowland side in a house that is arranged over a site with a difference in height. It can be applied to buildings other than residences, such as accommodation facilities and office buildings, as long as the building is installed, and the rooms located on the low-lying side can be used not only as built-in garages but also as warehouses and kitchens. good. In this embodiment, a case where a built-in garage is provided on the low land side of a house will be described. In the present application, "east", "west", "south" and "north" refer to "right", "left", "lower" and "upper" in FIG. It is separated without being fastened or fixed, and the edges are completely cut off.

The storage structure 1 on the site with a difference in height shown in FIG. A storage space 4 is formed above the arranged built-in garage 3. The site S1 shown in FIGS. 1 and 2 is a substantially rectangular site in plan view with steps extending in the north-south direction. and adjacent to adjacent land S2 and S3 via adjacent land boundary lines L3 and L4 in the north-south direction, respectively. A house 2 elongated in the east-west direction is arranged on the site S1, and an entrance porch 51 arranged on the south side of the house 2 and the road R1 are accessible by an entrance approach 52. - 特許庁The road surface level of the first front road R1 is lower than the road surface level of the second front road R2, and the height difference H1 of the site S1 shown in FIG. An approach staircase 52a is formed to eliminate the above.

As shown in FIG. 1, the house 2 is a three-story building, and the first floor has a height difference between the east side and the west side. and the second floor to form a skip-floor space. As shown in FIG. 2, the first floor of the house 2 has an entrance 6 consisting of an entrance dirt floor 61 and an entrance hall 62, a Japanese-style room 7 adjacent to the west of the entrance 6, a closet 8 and a first toilet 9 located to the north of the Japanese-style room 7, The cloakroom 10 and shoe closet 11 adjacent to the east side of the entrance 6, the staircase 12 connecting the first and second floors, the storage space 4 located on the east side of the staircase 12, the Japanese-style room 7, and the rooms except for the shoe closet 11 It consists of a connecting corridor 13 and a built-in garage 3 positioned below the storage space 4 shown in FIG. Each room except for the built-in garage 3 and the storage space 4 is arranged on the high ground side, and the built-in garage 3 on the low ground side can be accessed by stairs 14 shown in FIG. As shown in FIG. 1, the LDK 15 where the family gathers, the second toilet 16, the closet 17 for the main bedroom are arranged on the second floor of the house 2, and the common closet 18 and the children's room 19 are arranged on the third floor.

The built-in garage 3 shown in FIG. 1 is a space for parking vehicles owned by the residents, and can be moved to and from the first front road R1 by opening the shutter SS installed on the east side. In addition, the storage space 4 formed above the built-in garage 3 is a space for storing articles used by the residents for their hobbies, collections of books, etc., and the floor level is the first floor level on the high ground side. The height of the ceiling surface is formed to be substantially the same as the height of the ceiling surface of the corridor 13, and the ceiling height is lower than that of a normal room. Since the storage space 4 is arranged facing the landing 12a of the staircase 12 on the first floor and can come and go with the staircase 12, the residents can use the entrance hall 62 and the staircase through which they pass when going out or coming home. It is possible to shorten the movement from the LDK 15 on the second floor facing 12 to the storage space 4 and effectively omit the storage flow line.

The ceiling height H2 of the corridor 13 shown in FIG. 1 is about 2400 mm to 2500 mm, the ceiling height H3 of the built-in garage 3 is about 2200 mm to 2600 mm, and the ceiling height H4 of the storage space 4 is 1300 mm to 1400 mm or less. By keeping the ceiling height H4 of the storage space 4 low in this way, the storage space 4 becomes an attic space under the Building Standards Act, and the part where the storage space 4 is arranged is not calculated in the number of floors. Therefore, the increase in the number of floors makes it possible to improve the fire resistance performance required by law and to avoid an increase in the number of equipment to be installed, thereby effectively suppressing the construction cost of the building. Moreover, since the built-in garage 3 arranged on the lowland side is a parking lot that does not require a high ceiling height, the upper space of the built-in garage 3 can be effectively utilized as a storage space 4 in the form of a skip floor.

Next, a support structure for the storage space 4 will be described. As shown in FIGS. 3 and 4, the floor 4a of the storage space 4 is supported from below by a steel frame A formed by joining a plurality of shaped steels, and directly supports the floor 4a of the storage space 4. It is composed of a gantry beam A1 and a column A2 that supports the gantry beam A1 from below. The frame beam A1, which is H-shaped steel shown in FIG. 5, is assembled in consideration of the planar shape of the storage space 4 shown in FIG. The orientation of the flanges of the H-section steel is adjusted so that the flanges of the adjacent H-section steel alternate with respect to each other in consideration of the horizontal force acting on.

The steel frame frame A shown in FIGS. 3 and 5 is a member formed separately from the beams B1 and pillars B2 that support the main body of the house 2 excluding the floor 4a of the storage space 4. It supports only the floor 4a. As shown in FIG. 5, the columns A2 of the steel-frame pedestal A are supported and fixed on a pedestal foundation C2 that is separate from the building foundation C1 that supports the pillars B2, and the pillars B2 are completely separated from each other. state. The building foundation C1 and the frame foundation C2 are reinforced concrete foundations that are constructed at the same time and are structurally integrated. has little effect on the structure of House 2. In other words, when evaluating the structure of the main body of the house 2, only the influence of the steel frame frame A on the structure below the frame foundation C2 should be considered. Therefore, even if the storage space 4 is installed above the built-in garage 3, the effect on the structural analysis of the house 2 is small, and complication of the structural evaluation of the entire house 2 can be effectively avoided. In addition, since the steel frame A is independent from the beam B1 and the column B2, and the foundation to be supported is different from the two members B1 and B2, the steel frame A is constructed at the same time as the beam B1 and the column B2 are erected. no need to do Therefore, there is no risk that the steel frame frame A will complicate the construction of the beam material B1 and the column material B2 and delay the construction period of the entire house 2. The floor 4a of the storage space 4 may be finished by sequentially placing flooring materials such as lightweight foamed concrete, particle board, and flooring material on the upper portion of the steel frame frame A. As shown in FIG.

In this way, the storage structure 1 of the site with a difference in height according to the present application suppresses the ceiling height of the built-in garage 3, which normally becomes unnecessarily high, and forms a skip-floor type storage space 4 above the built-in garage 3. Therefore, the space above the built-in garage 3 can be effectively utilized. In addition, since the floor 4a of the storage space 4 is supported from below by a steel frame A that is formed independently of the beams B1 and pillars B2 that support the main body of the house 2 excluding the floor 4a, Even if the storage space 4 is installed, the influence on the structural evaluation of the house 2 can be minimized.

In this embodiment, the case where the storage space 4 is installed above the built-in garage 3 of the house 2 has been described. In that case, for example, items to be used indoors are stored in the storage space 4, and outdoor goods and sporting goods to be used outdoors are stored in the warehouse. In addition, when a room other than a parking lot is arranged on the lowland side, an opening or stairs leading to the lowland side room may be installed on the floor 4a of the storage space 4 as necessary. You may improve convenience by making it possible to go back and forth between.

The embodiments of the present invention are not limited to those described above, and can be modified as appropriate without departing from the spirit of the present invention.
