[Industrial Field of Application] The present invention relates to the structure of medium-to-high-rise buildings, and in particular, the present invention relates to the structure of medium-to-high-rise buildings, and in particular, on the first floor of a building, multiple rows of housing units constituting the housing units on the first floor are arranged in front, back, left, and right. This relates to 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 integrated with each other.

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. Incidentally, even in this type of housing complex, in order to reduce redundant costs of time, materials, and labor and to obtain high-quality housing, prefabricated housing like single-family houses has been promoted.

FIGS. 10 and 11 show conventional examples of construction techniques for such prefabricated mid-to-high-rise buildings.

The unit construction method shown in FIG. 10 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 unit construction method shown in FIG. 11 is also called the 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.

[0007]

[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. 10, the dwelling unit 2 is lifted by the crane 3 via the lifting plate 4 to a position facing the insertion portion 1a of the space frame 1, and the dwelling unit 2 is lifted from the insertion portion. Since it has to be pushed into 1a, the efficiency of construction work on site is poor.
Another problem is that a work space must be secured in front of the space frame 1 to allow the housing unit 2 to face it.

Second, in the unit construction method in which a building is constructed 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.

The present invention has been proposed in view of the above-mentioned circumstances, and its purpose is to increase the rigidity of at least one row of housing units stacked in a vertical direction to be higher than the rigidity of housing units in other rows. In addition to strengthening the building, a reinforced housing unit is also installed horizontally on at least one of each floor of the building, and these reinforced housing units are responsible for the horizontal load, thereby reducing the construction cost of the entire building. The purpose of the present invention is to provide a structure for medium-to-high-rise buildings that can improve the efficiency of on-site construction work.

[0011]

[Means for Solving the Problems] The structure of a mid-to-high-rise building according to the present invention is such that on the first floor of the building, multiple rows of housing units constituting the housing units on the first floor are arranged in the front, back, left and right, and each housing unit is placed above each housing unit. A medium-to-high-rise building constructed by stacking housing units constituting each floor of a building and integrating each housing unit adjacent to each other in the front, rear, left, right, top, and bottom, the housing unit forming at least one row along the vertical direction among the housing units. is characterized by having stronger rigidity than other housing units, and furthermore, reinforced housing units with increased rigidity are also arranged horizontally on at least one floor of each floor of the building. It is something.

[0012] In order to further strengthen the rigidity of the entire building, it is preferable that at least one of the floors of the building be constructed entirely of reinforced housing units with increased rigidity.

[0013]Furthermore, as the reinforced housing unit,
Four pillars, an upper beam and a lower beam that connect the upper and lower ends of these pillars, and six sides (front, rear, left, right, top, and bottom) surrounded by these pillars, the upper beam, and the lower beam. Among these, examples include those constructed from braces built into at least two adjacent surfaces, and rigid reinforcement members such as load-bearing walls.

[0014]

[Operation] According to the present invention, by stacking the housing units with the highest rigidity among the housing units constituting the building (reinforced housing units), a row of housing units with high rigidity is created. Since at least one of the floors of the building is more rigid than the other floors, the building can have a frame structure with increased rigidity against horizontal forces, and
Horizontal forces applied to the building are transmitted to the housing units in rows and floors with reinforced rigidity (reinforced housing units), and are taken care of by the reinforced housing units, so that the horizontal force applied to the building is This makes it possible to reduce the strength of the

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

FIG. 1 is a schematic perspective view showing the basic structure of a mid-to-high-rise building according to the present invention. The structure of this mid-to-high-rise building is basically constructed in a box shape with four columns 10a and an upper beam section 10b and a lower beam section 10c that connect the upper and lower ends of these columns 10a, respectively. A plurality of rows of housing units 10 are arranged from the first floor of the building in the front, rear, left and right directions (in the illustrated example, four rows each in the front, rear, left and right), and the housing units 10 constituting each floor of the building are stacked on top of each housing unit 10. It has a basic structure in which the housing units 10 adjacent to each other in the front, rear, left, right, top and bottom are mutually integrated.

However, in the present invention, at least one row of the housing units (reinforced housing unit) 10A among the housing units 10 is made more rigid than the other housing units 10, and furthermore, each floor of the building is The main feature is that a reinforced housing unit 10A with increased rigidity is also arranged horizontally on at least one floor.

In this embodiment, the reinforced housing units 10A with reinforced rigidity are stacked at the four corners of the building, and the housing units 10A are placed on each floor in the four corner rows.
In addition, reinforced housing units 10 are installed on the fourth floor of the building to connect to the rows of reinforced housing units 10A at the four corners.
A is also arranged horizontally.

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.
The housing units 10 are installed between these reinforced housing unit rows R, and the fourth floor of the building is constructed of the reinforced housing units 10A.

FIG. 2 shows a perspective view of the reinforced housing unit 10A. In the illustrated example, the reinforced housing unit 10A
The entire structure is a square box type, and more specifically, there are pillars 10a erected at the four corners, and these pillars 10.
An upper beam part 10b and a lower beam part 10 span between the upper end and lower end of a to form the upper and lower frameworks of the unit.
c, and walls 10d provided on the six inner and upper surfaces of the unit as well as on the two sides facing the exterior of the building.

[0021]The wall body 10d has a column part 10a and an upper beam part 10b to increase the rigidity of the dwelling unit 10A.
, is provided inside the lower beam portion 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 dwelling unit 10A is not limited to the example shown in FIG. 2, and various forms may be adopted depending on the arrangement position of the reinforced dwelling 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.

[0025] 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, 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.

FIG. 6 also 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.

By the way, the column section 10a that bears the vertical load of the unit must have a larger column cross section as the building becomes more multi-story. This is the treatment of furniture, etc.

[0031] That is, in the housing unit of a detached house, the cross-sectional size of the column portion 10a is set to be constant;
The dimensions of furniture, etc. are predetermined in accordance with the internal dimensions La and Lb of the column portion 10a, but when the building becomes a multi-story building of medium to high-rise buildings or higher, the cross-sectional shape of the column portion 10a may be enlarged. In order to reinforce the pillars, the internal dimension L between the pillars
a and Lb change depending on the size of the column cross section, making it impossible to assemble furniture of a predetermined size between the columns.

Therefore, in the embodiment, as shown in FIG.
When the inner 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 example,
The feature is that the size of the column cross section surrounded by the module cores M-M that intersect in the front, rear, left, and right directions is constant, and the width of the column is increased based on this portion.

[0033] This concept is based on the beam parts 10b and 10c.
Needless to say, the same applies to the case where the cross section of is increased.

Furthermore, as reinforcement techniques for the dwelling unit units 10 and 10A, it goes without saying that not only methods of increasing the cross section of columns and beams, but also methods of reinforcing wall thickness, load-bearing walls, etc. can be applied.

On the other hand, 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.

In the illustrated example, the dwelling unit is constructed of only a so-called frame, but inside the dwelling unit there are a bath unit, a sanitary unit,
It goes without saying that a configuration in which interior parts such as partition furniture are assembled in advance is also possible.

[0037] Furthermore, the length, width, and
Dimensions such as height are set.

Next, the operation of the structure of the medium-to-high-rise building 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.

[0042] When constructing the fourth floor of a building,
Reinforced housing unit 10A was installed across the entire 4th floor, and 4
The floor portion is the floor of the reinforced housing unit 10A.

[0043] The lifting of the dwelling unit 10 is carried out, for example, by using the reinforced dwelling unit 10A as a stand and installing a tower crane 20 on top of it, as shown in Fig. 8. do.

[0044] This construction method involves transporting the housing units 10A and 10 manufactured at a factory to the site and stacking them one by one using the tower crane 20, so that the work at the site is not necessary. can improve sexual performance.

[0045] In the structure of the mid-to-high-rise building constructed in this way, the most rigidly reinforced housing unit (reinforced housing unit) 10A is stacked at each of the four corners of the building to form a columnar frame with high rigidity. are constructed, and the fourth floor of the building is made more rigid than the other floors, so these frames can provide a frame structure that increases the rigidity of the building against horizontal forces.

[0046] Therefore, the horizontal force applied to the building is transmitted to the frames at the four corners, where the rigidity is the strongest, and the horizontal force is borne by these parts along with the fourth floor frame, so the horizontal force applied to the building is It does not impose a large burden on other dwelling units 10 in terms of structural design, and the strength required of the members constituting the dwelling unit 10 is small, so that a building can be constructed that is inexpensive as a whole structure.

In addition, in the embodiment, as shown in FIG. 7, when the internal dimensions La and Lb between the columns are constant and the cross section of the column portion 10a is made large, the width of the column is increased on the outside of the unit. Since we are trying to increase the size, there is also the advantage that it is not inconvenient to install unitized furniture that is incorporated inside the dwelling unit.

FIG. 9 shows another embodiment of the present invention. In this embodiment, reinforced housing units 10B having a smaller height than other reinforced housing units 10A are arranged on the fourth floor of a building. Even with this configuration, the same effects as in the previous embodiment can be achieved.

[0049] The shapes and dimensions of each component shown in the examples are merely examples, and can be variously changed based on the design requirements of the building to which it is applied. The position is also not limited to the example, and various arrangements can be adopted depending on the form of the building.

Further, in each of the embodiments shown in FIGS. 1 to 9, only the frame of the building is schematically shown, but 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 building rows and floors of housing units in which the most rigid housing units (reinforced housing units) are stacked among the housing units that make up the building, the rigidity of the building against horizontal forces is improved. Since it is possible to construct an increased frame structure, the horizontal forces on the building can be transferred to the stiffer frame, which can bear the horizontal forces, and the horizontal forces on the building can be transferred to other parts. It is an excellent technology that does not place a large burden on the structural design of the housing unit, requires less strength from the members that make up the housing unit, and therefore allows the construction of a building that is inexpensive as a whole. be effective. Furthermore, since the building can be constructed using the basic process of stacking housing units, there is an advantage that workability on site can be improved.
