Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to dwelling units and mid-to-high-rise buildings made up of dwelling units, and in particular, to a plurality of pillars and a structure that spans between the upper and lower ends of the pillars to cover the ceiling and floor. The present invention relates to a housing unit configured in a box shape with an upper beam portion and a lower beam portion forming a frame of a section, and a mid-to-high-rise building comprising this housing unit.

0002

[Prior Art] In recent years, due to the shortage of land in large cities and to accommodate the required number of housing units, apartment complexes in urban areas have been constructed from medium-rise apartment buildings to high-rise apartment complexes with, for example, 10 to 15 floors. It has become.

[0003] These are generally SRC structures whose pillars are mainly made of H-shaped steel, the girder rows are large PC boards that integrate the steel beams and wall parts, the door boundary walls are PC boards with braces, and the floors are made of SRC structures. It was constructed on-site and basically applied the construction methods used for conventional office buildings.

[0004] By the way, even in this type of housing complex,
Prefabricated houses, such as single-family houses, are becoming more popular in order to reduce redundant costs in time, materials, and labor, and to obtain high-quality housing.

FIGS. 9 and 10 show conventional examples of construction techniques for such prefabricated mid-to-high-rise buildings.

The unit construction method shown in FIG. 9 involves inserting a housing unit 2 assembled into a box shape into a space frame 1 whose main structure is H-shaped steel, and the housing unit 2 is lifted up by a crane 3. It is placed on a lifting plate 4 which also serves as a pushing jig, faces the insertion portion 1a of the space frame 1, and is inserted into the insertion portion 1a by an insertion device provided on the lifting plate 4.

The unitization method shown in FIG. 10 is also called a block construction method, in which steel-framed space units (dwelling unit units) 5 are stacked on site using a crane 6. The space units 5 that can be stacked on site have a width of 3,150 mm and a depth of 1 mm.
The standard size is 1,270 mm, height 2,670 mm, and weight 9 to 10 tons.The structure is a rigid frame in the column direction and a multi-column Vierendir truss in the span direction, and the outer wall of the unit is Curtain walls made of steel-resistant steel plates are pre-installed at the factory, and sashes and glass are also installed at the factory.

[0008]

[Problems to be Solved by the Invention] However, the above-mentioned unit construction method still has the following problems.

First, in the unit construction method as shown in FIG.
Since it is necessary to lift the space frame 1 to a position facing the insertion part 1a and push the dwelling unit 2 into the insertion part 1a, the efficiency of construction work on site is poor, and it is also necessary to place the dwelling unit 2 in front of the space frame 1. The problem is that it is necessary to secure a work space for the workers to do the work.

Second, in the unit construction method of building a building by stacking housing units 5 as shown in FIG.
In order to improve the strength against vertical loads and horizontal loads, the structure of each housing unit must be strengthened, which increases the cost of each housing unit and increases the overall cost.

[0011] Therefore, as a result of intensive research in order to solve the above-mentioned problems, the inventor of the present invention has arranged multiple rows of housing units constituting the housing units on the first floor on the first floor of a building, front and back, left and right, and each housing unit In a mid-to-high-rise building in which the housing units constituting each floor of the building are stacked on top of each other and the adjacent housing units in the front, back, left, right, top and bottom are mutually integrated, at least one row of housing units stacked continuously in the vertical direction The rigidity is made stronger than that of the housing units in other rows,
By making this reinforced row of housing units bear the horizontal load, it is possible to construct a strong mid-to-high-rise building by reinforcing at least one row of housing units, thereby reducing construction costs. They came up with the idea that it would be possible to increase the efficiency of construction work on site.

However, when reinforcing a dwelling unit, if the cross sections of the columns and beams that make up the dwelling unit are made larger, the internal dimension between the columns and beams will increase due to the increased cross sections of the columns and beams. Due to the smaller size, interior components such as furniture to be assembled into the dwelling unit cannot be accommodated, leading to problems such as the inability to standardize interior components.

The present invention has been proposed in view of the above-mentioned circumstances, and its purpose is to provide a dwelling unit and a medium-to-high-rise building consisting of the dwelling unit, in which the interior parts to be assembled in the dwelling unit can be shared. It is about providing.

[0014]

[Means for Solving the Problems] In order to achieve the above object, the present invention comprises a plurality of pillars, which are spanned between the upper and lower ends of the pillars to constitute a framework for a ceiling and a floor. A dwelling unit configured in a box shape with an upper beam part and a lower beam part, wherein the pillar part and the beam part each have a certain distance from the module core of the unit to the inner surface of the pillar part and the beam part. The unit is reinforced by extending the width of the side surface of the column toward the outside of the unit with reference to the inner surface of the column and beam.

[0015] In order to achieve the same object, the present invention provides a mid-to-high-rise building comprising dwelling units, in which multiple rows of dwelling units constituting the dwelling units on the first floor are arranged in front, rear, left and right on the first floor of the building. A mid-to-high-rise building constructed by stacking the housing units constituting each floor of the building on top of each housing unit and integrating the adjacent housing units in the front, back, left, right, top and bottom of the building, wherein the housing unit is connected to a plurality of pillars. and an upper beam section and a lower beam section that span between the upper and lower ends of this column section and constitute the framework of the ceiling section and floor section. The module is installed in the unit in such a way that it penetrates the module core and the outer surfaces of the columns and beams protrude outward from the module core. The feature is that the distance to the side is set to a constant size.

[0016]

[Operation] According to the present invention, by widening the width of the columns and beams outward from the unit while keeping the width dimensions of the columns and beams inside the module core constant, the cross sections of the columns and beams can be increased. As a result, the internal dimension between the columns and beams is always maintained at a constant size, and interior components incorporated into the dwelling unit can be standardized.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

First, the basic structure of a residential unit according to the present invention and a mid-to-high-rise building comprising this residential unit will be explained with reference to FIGS. 1 to 6.

This mid-to-high-rise building is basically assembled into a box shape with four pillars 10a and an upper beam part 10b and a lower beam part 10c that connect the upper and lower ends of these pillars 10a, respectively. 10 dwelling units in one building
A plurality of rows (four rows each in the front, rear, left, and right directions) are arranged from the floor to the front, back, left, and right (in the illustrated example, four rows each in the front, back, left, and right), and the housing units 10 constituting each floor of the building are stacked on top of each housing unit 10, so that each housing unit adjacent to the front, rear, left, right, top, and bottom It has a basic structure in which the units 10 are mutually integrated.

In this embodiment, the reinforced housing units 10A, which are more rigid than the housing unit 10 placed in the center of the building, are stacked at the four corners of the building, and the housing units placed on each floor in the rows of the four corners are stacked. The horizontal load of the building is borne by the unit 10A.

That is, in the building shown in FIG. 1, reinforced housing units 10 are installed at each of the four corners of the building to be constructed.
A strengthened housing unit row R is set up by stacking A.
A housing unit 10 is installed between these reinforced housing unit rows R.

[0022]The reinforced housing unit 10A is
As shown in FIG. 2, the entire structure is a square box type, and to be more specific, there are pillars 10a erected at the four corners, and a bridge between the upper and lower ends of these pillars 10a. An upper beam part 10b and a lower beam part 10c which form the upper and lower frameworks of the unit, and walls 10d each provided on the upper and lower inner surfaces of the unit and on the two sides facing the outside of the building. It is constituted as a subject.

[0023] Furthermore, the wall body 10d is connected to the housing unit 1.
In order to increase the rigidity of 0A, the column part 10a, the upper beam part 10b,
It is provided inside surrounded by the lower beam part 10c, and serves as a so-called seismic element to share the horizontal force that acts on the unit during an earthquake.

In the drawing, the wall 10d is used as an earthquake-resistant element, but the present invention is not limited to this illustrated example. For example, a brace, a truss, etc. may be provided in place of the wall 10d. You can do it like this. Further, it is also possible to form an opening such as a window in the wall 10d.

Furthermore, it goes without saying that the reinforced housing unit 10A is not limited to the example shown in FIG. 2, and that various forms may be adopted depending on the arrangement position of the reinforced housing unit 10A.

FIGS. 3 to 5 are schematic perspective views showing the basic form of such a reinforced housing unit 10A.
In the example shown in FIG. 3, the reinforced housing unit 10B has pillars 10a erected at the four corners, and upper beams 10b that span between the upper and lower ends of these pillars 10a to form the upper and lower frameworks of the unit. and the lower beam part 10c and the wall body 10 assembled on two adjacent sides of the dwelling unit.
It is constructed in a square box shape based on d.

[0027] Furthermore, the reinforced housing unit 10C shown in FIG.
Basically, similarly to the reinforced housing unit 10B shown in FIG.
Upper beam part 10b and lower beam part 1 span between the upper end and lower end of 0a and serve as the upper and lower frameworks of the unit.
0c, but in this example, one more wall 10d is attached to the side of the unit to strengthen its rigidity.

Furthermore, the reinforced housing unit 10 shown in FIG.
In D, the pillars 10a erected at the four corners and these pillars 1
Upper beam part 10b and lower beam part 1 span between the upper end and lower end of 0a and serve as the upper and lower frameworks of the unit.
Walls 10d are attached to the four sides of the frame (that is, around the frame), which is made up of 0c, thereby increasing the rigidity of the unit.

Furthermore, in the present invention, in order to further strengthen the rigidity of the dwelling unit, although not shown in the drawings, rigidity reinforcing members such as the wall 10d are further assembled on the upper and lower surfaces of the unit, thereby increasing the strength and rigidity of the unit. Of course, the number may be increased. In addition, in the illustrated examples shown in FIGS. 3 to 5 described above, the wall body 10d is used as the rigidity reinforcing member.
was applied, but it is also possible to replace it with braces, etc.

On the other hand, FIG. 6 shows the reinforced housing unit 10.
In the illustrated example, the dwelling unit 10 has pillars 10a erected at the four corners, and a wall between the upper and lower ends of these pillars 10a. It is mainly composed of an upper beam part 10b and a lower beam part 10c which are spanned to form the upper and lower frames of the unit, and small beam parts 10f which are installed above and below the unit.

The configuration of the dwelling unit 10 is not limited to the illustrated example, and can be modified in various ways based on the design requirements of the building to be constructed.

[0032] Further, as a means for connecting the dwelling unit units, for example, a method such as bolt connection is applied, but other means may be used as long as the dwelling unit units can be integrated with each other.

Furthermore, in the illustrated examples shown in FIGS. 1 to 6, the dwelling unit is constructed of only a so-called frame, but inside the dwelling unit there are interior components such as a bath unit, sanitary unit, partition furniture, etc. Needless to say, it is also possible to have a configuration in which the components are assembled in advance.

Furthermore, the length, width, height, and other dimensions of the dwelling units are set within the limits of the trucks used to transport them from the factory to the site.

Next, the basic idea of the present invention will be explained with reference to FIG.

Column portion 10a that bears the vertical load of the unit
As a building becomes more multi-story, the cross section of the columns must be made larger, but the problem in this case is the treatment of interior parts such as modular furniture that are assembled into the unit.

[0037] In other words, in a residential unit of a detached house, there is no need to consider the cross-sectional increase of the column 10a unlike in a residential unit for a medium-to-high-rise building. It is possible to standardize parts by determining the dimensions of furniture, etc. in advance, but if the building becomes a multi-story building with medium to high-rise buildings or higher, it is necessary to strengthen the column by enlarging the cross-sectional shape of the column 10a. Furthermore, the internal dimensions La and Lb between the pillars change depending on the size of the cross section of the pillar, making it impossible to assemble furniture of a predetermined size between the pillars.

Therefore, in the present invention, as shown in FIG.
When the internal dimensions La and Lb between the columns are kept constant and the cross section of the column portion 10a is increased, the width of the column is increased toward the outside of the unit. That is, in the present invention,
The column portion 10a and the beam portion 10b are connected to each other from the module core M-M of the unit.
The main feature is that it is reinforced by extending the width of the side of the column outwards from the inner surface of the column and beam, with the distance to the inner surface set to a certain size. That is.

[0039] Furthermore, this concept also applies to the beam parts 10b and 10c.
Needless to say, the same applies to the case where the cross section of is increased.

[0040]More specifically, the pillar portion 10a and the beam portion 10b each correspond to the module core M of the unit.
- M is installed in the unit with the outer surfaces of the column 10a and the beam 10b protruding outward from the module core M-M, and the column 10a and the beam 10b are installed in the unit from the module core M-M of the unit, respectively. The distance to the inner surface of the portion 10b is set to a constant size.

[0041] Next, the operation of the dwelling unit and the mid-to-high-rise building composed of the dwelling unit constructed as described above will be explained.

As shown in FIG. 1, in order to construct this mid-to-high-rise building, the reinforced housing unit 10A and housing unit 10 are manufactured in a factory or the like, and these are transported to the site by truck or the like, and the first floor The housing units 10A and 10 are arranged in four rows and four rows.

The housing units 10A, 10 are arranged so that the reinforced housing units 10A are located at the four corners of the building, and the housing units 10 are arranged between these reinforced housing units 10A.

Next, by using a crane, the reinforced housing unit 10A and the housing unit 10 are successively stacked on top of the reinforced housing unit 10A and the housing unit 10, respectively, and the adjacent units in the front, back, left and right are fastened together, as shown in FIG. A mid-to-high-rise building like the one shown is completed.

[0045] As shown in Fig. 8, the housing unit 10 can be lifted by, for example, using the reinforced housing unit 10A as a stand and installing a tower crane 20 on top of the reinforced housing unit 10A. do.

[0046] This construction method involves transporting the housing units 10A and 10 manufactured at the factory to the site and stacking them one by one using the tower crane 20, so there is no need for on-site work. can improve sexual performance.

In this example, as shown in FIG. 7, the cross sections of the columns and beams are increased by increasing the width of the columns and beams outward from the unit while keeping the width dimension inside the module core constant. As a result, it is possible to standardize interior parts such as unitized furniture built into the interior of the housing units in all the housing units 10A and 10 that make up the building, making it inconvenient to install interior parts. It has the advantage that it never happens.

Furthermore, in this embodiment, the most rigidly strengthened dwelling units (reinforced dwelling units) 10A are stacked at each of the four corners of the building to construct a columnar frame with high rigidity. It is possible to create a frame structure that increases the rigidity of the building. Therefore, the horizontal force applied to the building is transmitted to the frame at the four corners where the rigidity is the strongest, and the horizontal force is borne by these parts, so the horizontal force applied to the building is transferred to the other housing units 10 in the structural design. Moreover, it does not impose a large burden, and the strength required of the members constituting the dwelling unit 10 is small.
Therefore, it is possible to construct an inexpensive building as a whole.

[0049] The shapes and dimensions of each component shown in the examples are merely examples, and can be changed in various ways based on the design requirements of the building to which it is applied, and the arrangement position of the reinforced housing units 10A may also vary. However, the arrangement is not limited to the examples, and various arrangements can be adopted depending on the form of the building.

Furthermore, in the embodiments shown in FIGS. 1 to 8,
Although only the building frame is schematically shown, it goes without saying that each dwelling unit is coated with fireproof coating and the like.

[0051]

[Effects of the Invention] As explained above, according to the present invention,
By widening the width of the columns and beams outward from the unit while keeping the inner width of the module core constant, the cross-sections of the columns and beams are increased, so the internal dimensions between the columns and beams are This provides excellent effects such as always maintaining constant dimensions and making it possible to standardize the interior parts installed inside the dwelling unit.
