Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a dwelling unit that constitutes a living space inside a frame consisting of four pillars, and an upper beam and a lower beam that connect the upper and lower ends of these pillars, respectively. In particular, the present invention relates to a housing unit suitable for application to a medium-to-high-rise building constructed by stacking housing units.

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-beam steel, the girders 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. 11 and 12 show conventional examples of construction techniques for such prefabricated mid-to-high-rise buildings.

The unit construction method shown in FIG. 11 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. 12 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.

[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 shown in FIG. 11, the dwelling unit 2 is lifted by the crane 3 via the lifting plate 4 to a position facing the insertion part 1a of the space frame 1, and the dwelling unit 2 is lifted from the insertion part. 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.

[0010] Second, in the unit construction method in which a building is constructed by stacking housing units 5 as shown in Fig. 12,
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 integrated, at least one row of housing units stacked continuously in the vertical direction If the rigidity is made stronger than that of the housing units in other rows, and the reinforced row of housing units is made to bear the horizontal load, a mid-to-high-rise building with high strength can be created by reinforcing at least one row of housing units. We came up with the idea that since we can construct things, we can reduce construction costs and increase the efficiency of on-site construction work.

However, even in mid-to-high-rise buildings made up of such dwelling unit units, there are various lengths of the dwelling unit units, and in particular, when the dwelling unit itself is made as long as possible, the beams become long and the unit becomes long. There are problems in that it increases the size of the housing unit and increases the cost of the housing unit.

The present invention has been proposed in view of the above circumstances, and its purpose is to reduce costs by eliminating the need to increase the length of the beam even if the length of the dwelling unit becomes longer. The aim is to provide housing units that can

[0014]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a frame consisting of four pillars, and an upper beam and a lower beam that connect the upper and lower ends of these pillars, respectively. In a dwelling unit that constitutes a living space inside the frame, the frame is set to the longest dimension ratio within the length limit of the truck bed, and the frame has a structure in which the upper beam is placed above the lower beam. Supporting auxiliary pillars are positioned in the length direction of the dwelling unit and erected near the pillars, and auxiliary pillars are installed between these auxiliary pillars and the four corner pillars from the upper end of the pillar. The feature is that a brace material is disposed toward the lower end of the section.

[0015] In addition, in order to achieve the same object, the present invention provides a plurality of rows of housing units constituting the housing units on the first floor on the first floor of a building, arranged in front, back, left and right, and above each housing unit on each floor of the building. In a medium-to-high-rise building constructed by stacking housing units constituting a building and integrating each housing unit adjacent to each other in the front, rear, left, right, top, and bottom, the housing units are formed by four pillars and the upper and lower ends of these pillars, respectively. It is assembled into a box shape by connecting the upper beam part and the lower beam part, and at least one of these dwelling unit units is set to have a long dimension ratio in the horizontal direction, and the upper beam part is set above the lower beam part. Auxiliary pillars supporting the housing unit are located in the length direction of the dwelling unit and erected near the pillars, and between these auxiliary pillars and the four corner pillars, support pillars are installed from the upper ends of the pillars. The feature is that a brace member is provided toward the lower end of the column.

[0016]

[Operation] According to the present invention, an auxiliary column part that supports a beam extending in the length direction of the frame is installed in the frame that constitutes a dwelling unit, and furthermore, between the auxiliary column part and the column part, Since the brace material was installed in the beam, the auxiliary column and the brace material can resist the bending moment applied to the beam, and the amount of deflection in the center of the frame can be reduced against uniformly distributed loads.
It becomes possible to reduce beam formation.

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 medium-to-high-rise building constructed using the housing unit according to the present invention. This mid-to-high-rise building is basically a housing unit built into a box shape by four pillars 10a, and upper and lower beams 10b and 10c that connect the upper and lower ends of these pillars 10a, respectively. 10, 10A, 20
are arranged in multiple rows (in the illustrated example, four rows each in front, rear, left, and right) from the first floor of the building, and each housing unit 10, 10
A. Dwelling unit 10 that constitutes each floor of the building above 20
, 10A, 20 are stacked up, and the basic structure is such that the adjacent dwelling units 10, 10A, 20 are mutually integrated in the front, back, left, right, top and bottom.

In the embodiment, the housing unit 10A whose rigidity is the most reinforced among the housing units 10, 10A, and 20 (reinforced housing unit) is arranged at two diagonally opposite corners of the building. They are then stacked upwards to take on the horizontal load of the building.

That is, in the building shown in FIG. 1, reinforced housing unit rows R each consisting of reinforced housing units 10A are provided at two opposite corners of the building to be constructed, and these reinforced housing unit rows R are A dwelling unit 20 according to the present invention and a dwelling unit 10 having the same size as the reinforced dwelling unit 10A are installed between them.

FIG. 2 shows a housing unit 20 according to the present invention.
This is a perspective view of the dwelling unit 2 according to the embodiment.
0, like other housing units, has a rectangular box shape as a whole, and more specifically, four pillars 20a and the upper and lower ends of these pillars 20a are connected to each other. A living space is configured inside a frame K consisting of an upper beam portion 20b and a lower beam portion 20c.

The frame K is constructed such that its length L is longer than the width and height dimensions W and T to the maximum extent within the length limit of the truck bed. In addition, in the frame K, auxiliary pillar parts 20d that support the upper beam part 20b on the lower beam part 20c are located in the length direction of the dwelling unit 20 and are erected in the vicinity of the pillar parts 20a. At the same time, brace members 20e are provided between the auxiliary column portions 20d and the four corner column portions 20a, extending from the upper end of the column portion 20a toward the lower end of the auxiliary column portion 20d.

Furthermore, inside the framework surrounded by the upper beam part 20b and inside the frame surrounded by the lower beam part 20c, there are small beam parts 20f extending in the width direction of the dwelling unit 20, respectively. The units 20 are arranged at intervals along the length direction.

On the other hand, FIG. 3 shows the reinforced housing unit 10A.
In the illustrated example, the entire reinforced housing unit 10A is configured in the shape of a square box, and basically has pillars 10a erected at the four corners, and these pillars Upper and lower beam parts 10b and 10c span between the upper and lower ends of 10a and form the upper and lower frameworks of the unit, as well as the upper and lower inner surfaces of the unit and the two sides facing the exterior of the building. It is mainly constituted by a wall body (rigidity reinforcing member) 10d provided respectively.

[0025] The wall 10d has a column part 10a and an upper beam part 10b in order 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 a load-bearing wall constituting an earthquake-resistant element, but the invention is not limited to this illustrated example. For example, instead of the wall 10d,
Braces, trusses, etc. may also be provided. Also,
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. 3, and that various forms may be adopted depending on the arrangement position of the reinforced housing unit 10A.

FIGS. 4 to 6 are schematic perspective views showing the basic form of such a reinforced housing unit 10A.
In the example shown in FIG. 4, 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.

[0029] 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. 4 to 6 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. 7 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.

[0035] 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.

[0037] 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.

[0038] 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 with each other.

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.

[0041] 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, a reinforced housing unit 10A and housing units 10 and 20 are manufactured in a factory or the like.
These are transported to the site by a truck or the like, and the housing units 10A, 10, and 20 are arranged in two vertical rows and four horizontal rows from the first floor.

The arrangement of these housing units 10A, 10, and 20 is such that the reinforced housing unit 10A is installed at two opposite corners of the building, and these reinforced housing units 1
Dwelling units 10 and 20 are arranged based on 0A.

In the illustrated example, the longer dwelling units 20 are arranged along the length of the reinforced dwelling unit 10A, and the dwelling units 10 and 20 are respectively installed at the center position.

[0046] Next, by using a crane, the reinforced housing unit 10A and the housing units 10 and 20 are successively stacked on top of the reinforced housing unit 10A and the housing units 10 and 20, respectively, and adjacent units in the front, back, left and right are fastened together. , a mid-to-high-rise building as shown in Figure 1 is completed.

[0047] The lifting of the dwelling unit 10, 20, etc. is carried out by lifting the reinforced dwelling unit 1, for example, as shown in Fig. 9.
A tower crane 30 is installed on the 0A as a stand, and the tower crane 30 is used for carrying out operations.

[0048] This construction method involves transporting the housing units 10A, 10, and 20 manufactured at a factory to the site and stacking them one by one using the tower crane 30. can improve workability.

[0049] In mid-to-high-rise buildings constructed in this way, the housing units (with the highest rigidity)
The 10A (reinforced dwelling units) are stacked at each corner of the building to construct a highly rigid column-like frame, so these frames can create a frame structure that increases the rigidity of the building against horizontal forces. can.

[0050] Therefore, the horizontal force applied to the building is transmitted to the frames at the two corners, where the rigidity is the strongest, and the horizontal force is borne by these parts. 10, 20 does not impose a large burden on the structural design, the strength required of the members constituting the dwelling units 10, 20 is small, and the overall structure of the building can be constructed at low cost.

Furthermore, in the embodiment, an auxiliary column part 20d that supports a beam extending in the length direction of the frame K is assembled into the frame K constituting the dwelling unit 20, and furthermore, this auxiliary column part 20d and Since the brace material 20e is installed between the column 20a, the auxiliary column and the brace material can resist the bending moment applied to the beam, and reduce the amount of deflection δ at the center of the frame under uniformly distributed loads. This makes it possible to reduce the beam size (see FIG. 10). Therefore, up to the maximum limit of the truck bed, the dwelling unit 2
Even if 0 is increased, there is no need to increase the beam size, and the dwelling unit can be manufactured at low cost. As a result, it is possible to improve the applicability of the long unit to unit-type medium-to-high-rise buildings.

Furthermore, in the embodiment, as shown in FIG. 8, when the internal dimensions La and Lb between the columns are kept constant and the cross section of the column section 10a is made large, the width of the column is increased on the outside of the unit. This has the advantage that it is not inconvenient to install unitized furniture that is incorporated inside the housing unit.

[0053] 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.

Further, in the embodiments shown in FIGS. 1 to 10, 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.

[0055]

As explained above, the present invention provides a living space inside a frame consisting of four columns and an upper beam section and a lower beam section that connect the upper and lower ends of these columns, respectively. In the housing unit, the frame is set to the longest dimension ratio within the length limit of the truck bed, and the frame is provided with an auxiliary column that supports the upper beam on the lower beam. , located in the length direction of the dwelling unit and erected near the pillars, and between these auxiliary pillars and the four corner pillars, from the upper end of the pillar toward the lower end of the auxiliary pillar. Since the beam is characterized by having a brace material arranged at the center, the auxiliary columns and the brace material can resist the bending moment applied to the beam, and the amount of deflection at the center of the frame can be reduced under uniformly distributed loads. This makes it possible to reduce the beam size, and even if the housing unit is enlarged to the maximum limit of the truck bed, there is no need to increase the beam size, and the housing unit can be manufactured at a low cost. It has the advantage of being able to
