The rigidity in the horizontal direction is also enhanced by attaching a beam to the middle floor, and preferably the top floor of the building, which extends by connecting the reinforced dwelling units in a ring shape in the horizontal direction. Therefore, the dwelling unit other than the corner of the building can reduce the strength required for the dwelling unit.

[0012]

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 configuration of the structure of a middle-high-rise building according to the present invention. The building shown in FIG. 1 has four rows of dwelling unit units 10 and 10A constituting a first-floor dwelling unit on a foundation 20, and four rows of front and rear and left and right units are arranged on each dwelling unit unit 10 and 10A.

The structure of the joist 30 for connecting the upper ends of the reinforced dwelling unit rows R in a ring shape is not limited to the truss structure as described above, and various design changes are possible. It is also possible to use a flat plate structure having ends. In addition, the girder 30 can also be used as a cooling tower or a platform for an elevated water tank.

Further, the berth 30 and the reinforced dwelling unit 1
The connection with 0A may be performed using a connecting plate, or a connecting rod may be connected to the upper end of the pillar 10a of the reinforced dwelling unit 10A on the top floor so as to be coaxial with the pillar 10a. It may be made to extend, and it may be made to connect berth 30 and reinforced dwelling unit 10A via this connecting rod. In short,
Any structure may be used as long as the beam 30 and the reinforced dwelling unit 10A are rigidly joined.

As described above, in this building, the vertically connected dwelling units forming the corners must be more rigid than the other dwelling units. Is not limited to the structure indicated by reference numeral 10A in the above embodiment. For example, in the example shown in FIG. 4, the reinforced dwelling unit 10 </ b> B has a square box-type box type as a whole, and specifically, pillars 10 a erected at four corners, and upper ends of these pillars 10 a. The upper beam 10b and the lower beam 10c which are bridged between the lower ends to form the upper and lower frames of the unit, and are provided on the inner and lower surfaces of the six units and the two side surfaces facing the outer surface of the building, respectively. The wall 10d is mainly configured. The wall 10d is provided inside the column 10a, the upper beam 10b, and the lower beam 10c in order to increase the rigidity of the dwelling unit 10B.

Further, in the example shown in FIG. 5, the reinforced dwelling unit 10C has pillars 10a erected at four corners, and bridges between the upper and lower ends of these pillars 10a to form upper and lower frameworks of the unit. The upper beam portion 10b and the lower beam portion 10c, and the wall 10d attached to two adjacent side surfaces of the dwelling unit are basically formed in a rectangular box shape.

Further, the reinforced dwelling unit 10D shown in FIG.
Basically, similarly to the reinforced dwelling unit 10B shown in FIG.
Upper beam part 10b and lower beam part 1 which are bridged between the upper and lower ends of the upper and lower parts of the unit 0a.
Although this is mainly composed of 0c, in this example, the wall 10d is further assembled to the side surface of one unit to increase the rigidity.

Further, the reinforced dwelling unit 10 shown in FIG.
In E, the pillars 10a erected at the four corners and these pillars 1
Upper beam part 10b and lower beam part 1 which are bridged between the upper and lower ends of the upper and lower parts of the unit 0a.
A wall 10d is attached to the four side surfaces (that is, the periphery of the frame) of the frame composed of the frames 0c and 0c to enhance the rigidity of the unit.

In the present invention, in order to further enhance the rigidity of the dwelling unit, although not shown, a rigidity reinforcing member such as a wall 10d is further attached to the upper and lower surfaces of the unit to reduce the proof strength and rigidity of the unit. Of course, it may be increased. In the example shown in FIGS. 4 to 7 described above, the wall 10d is used as the rigidity reinforcing member.
Was applied, but it is also possible to replace it with braces or the like.

In general, the pillar section 10a that bears the vertical load of the dwelling unit must have a larger pillar cross section as the building becomes a multi-story building. It is processing of furniture and the like. That is, as shown in FIG. 9, in general, when the inner dimensions of the dwelling unit are used, when the pillar 10 a having a rectangular cross section is used, the pillars 10 a, 1
The inner dimensions La and Lb between 0a are designed to be constant. On the other hand, the planar dimensions of the dwelling unit itself are defined by the dimensions of the module core MM that crosses the front, rear, left, and right directions. Therefore, the cross-sectional dimension (overhang allowance) at which the column portion 10a can protrude into the room is determined depending on the size between the module cores and the inner dimensions La and Lb of the room.

By the way, in this building, the dwelling units 10 of the same size are stacked, and the vertical load of the building is borne on the column 10a. Therefore, the strength of the column 10a is required to withstand the vertical load. It is necessary to make the cross-sectional dimension of the pillar portion 10a larger than that of a low-rise building in order to improve the height.

In order to solve this problem, in the embodiment,
As shown in FIG. 9, when a column 10 a having a rectangular cross section is used, for example, each of the dwelling unit units can be used without changing the cross-sectional dimension (extension allowance) of the column 10 a projecting into the room according to the vertical load of the building. The cross-sectional dimension of the pillar 10a is enlarged in an outdoor direction where the dwelling units are not adjacent to each other, such as a window side or a corridor side. As a result, the column 1 is maintained while keeping the module core spacing and the room internal dimensions La and Lb constant.
The vertical strength of 0a is assumed to withstand the vertical load of the building.

This concept is based on the idea that the beams 10b, 10c
It is needless to say that the same applies to the case where the cross section is enlarged. On the other hand, as shown in FIG. 3, in the case of using the pillar portion 10a having an L-shaped cross section, by changing the thickness of the pillar portion 10a, it does not significantly affect the volume of the interior living space A, There is an advantage that the required strength of the pillar 10a can be secured. Also, the dwelling units 10, 10
As a reinforcement technique of A, it goes without saying that not only a method of increasing the cross-section of columns and beams, but also a method of reinforcing wall thickness, bearing wall and the like is applied.

On the other hand, the dwelling units 10 arranged between the reinforced dwelling unit units 10A have the reinforced dwelling unit row R and the struts 31 and 3 both vertically and horizontally.
Since the stress is borne by the base 0 and the foundation 20, it may have relatively low rigidity. The dwelling unit 10 arranged between the reinforced dwelling unit 10A
FIG. 8 shows an example of the structure of FIG.

In FIG. 8, the dwelling unit 10 is
Pillars 10a erected at the four corners, an upper beam 10b and a lower beam 10c which are bridged between the upper and lower ends of the pillars 10a to form upper and lower frameworks of the unit;
It is mainly composed of small beams 10f provided above and below the unit. Of course, the configuration of the dwelling unit 10 is not limited to the illustrated example, and various changes can be made based on the design requirements of the building to be constructed.

The dwelling unit 10 (10A) may be connected to the dwelling unit and the foundation 20 by means of, for example, bolts. As long as they can be integrated, another method, for example, a fixing method using a dedicated connecting plate may be used.

Further, in the illustrated example, the dwelling unit is constituted by only a so-called frame, but inside the dwelling unit, a bus unit, a sanitary unit,
It goes without saying that a configuration in which interior members such as partition furniture are assembled in advance may be employed. Furthermore, these dwelling units may be limited in size, weight, such as length, width, height, etc., depending on transportation means for transporting the assembly unit to the site, road conditions, and the like.

Next, a method for constructing the building will be described with reference to embodiments. As shown in FIG. 1, in order to construct this middle-high-rise building, the reinforced dwelling unit 10A and the dwelling unit 10 are manufactured in a factory or the like, respectively, transported to a site by a truck or the like, and
On the 0, dwelling units 10A and 10 on the first floor are arranged vertically and horizontally by four units and fastened to the foundation 20.

The arrangement of the dwelling units 10A and 10 is such that the reinforced dwelling units 10A are installed at four corners of the building, and the dwelling units 10 are arranged between the reinforced dwelling units 10A.

Next, while the reinforced dwelling unit 10A and the dwelling unit 10 are respectively stacked on the reinforced dwelling unit 10A and the dwelling unit 10 on the first floor, the units adjacent to the front, rear, left and right are fastened. Then, to the upper ends of the dwelling units 10A and 10 constructed for each of the third floors, the dorsal beam 31 is attached while being rigidly joined to the pillar 10a of the reinforced dwelling unit 10A.

For example, as shown in FIG. 10, the dwelling unit 10 can be lifted by using the reinforced dwelling unit 10A as a base, installing a tower crane 40 thereon, and using the tower crane 40. To

Next, on the top of the dwelling unit 10A, 10 on the top floor constructed in this way, the berth 30 is attached to the upper end of the reinforced dwelling unit row R while being rigidly joined.
The middle and high-rise building as shown in FIG. 1 is completed by the above construction procedure.

The building constructed in this manner is a dwelling unit with the highest rigidity (enhanced dwelling unit) 10
A is stacked at each of the four corners of the building to form a columnar and highly rigid frame, that is, a reinforced dwelling unit row R, and a tie beam 31 that connects the upper end of the dwelling unit 10A in a horizontal direction annularly every three floors. Is provided, and also on the roof of the building, there is provided a berth 30 for connecting the upper end of the reinforced dwelling unit row R in a horizontal direction in a ring shape, so that the foundation 20, the reinforced dwelling unit row R, and the Beam 3
With the high rigidity frame composed of 0 and 31, it is possible to provide a frame structure that has increased rigidity not only against the load of the dwelling unit but also against combined vertical and horizontal stresses such as an earthquake.

In this frame structure, for example, horizontal stress applied to the building is transmitted to the frame of the four corners with the highest rigidity, and the girder 31 provided for each of a plurality of floors and the girder 30 at the top of the building are provided. At the same time, since horizontal stress is received in these parts, the horizontal stress applied to the building does not impose a large burden on the other dwelling unit 10 in structural design, and the strength required for the members constituting the dwelling unit 10 is reduced. Buildings that are small and therefore inexpensive as a whole structure can be constructed.

In the embodiment, as shown in FIG. 9, when the inner dimensions La and Lb between the columns are fixed and the cross section of the column portion 10a is enlarged, the width of the columns is set outside the unit. Since the size is increased, there is also an advantage that attachment of unitized furniture incorporated in the dwelling unit does not become inconvenient.

The various shapes, dimensions, and the like of the components shown in the embodiments are merely examples, and can be variously changed based on the design requirements of the building to which the invention is applied. Further, in each embodiment shown in FIGS. 1 to 10, only the frame of the building is schematically shown, but it is a matter of course that each dwelling unit is provided with a fireproof coating or the like.

[0044]

As described above, the present building is a middle-to-high-rise building, in which the dwelling units connected vertically in the respective corners are strengthened more rigidly than the other dwelling units. In addition, since a ridge that extends by connecting the reinforced dwelling unit in a horizontal direction in a ring shape is attached to the middle floor of the building, a skeletal structure with increased rigidity against vertical and horizontal stresses is constructed. As a result, it is possible to reduce the strength required for a dwelling unit having another normal strength different from the reinforced dwelling unit, and thus it is possible to construct an inexpensive building as a whole.

In addition, since the building can be constructed by the basic process by stacking the dwelling units, there is an advantage that workability at the site is improved.
