BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inside of a frame composed of four pillars, an upper beam connecting the upper ends of these pillars, and a lower beam connecting the lower ends of the pillars. The present invention relates to a dwelling unit that forms a living space.

[0002]

2. Description of the Related Art In recent years, due to a shortage of land in a large city and a reduction in the number of required housing units, in an urban area apartment building, a high-rise apartment building of, for example, 10 to 15 floors from the middle floor has been constructed. It has become.

[0003] These are generally made of SRC with columns mainly made of H-section steel, and the columns are large PC boards with integrated steel beams and wall parts, PC boards with beam braces, and floors with floors. It was built on site and basically applied the conventional office building construction technology. By the way, even in this type of multi-family housing, prefabricated housing such as a detached house is being promoted in order to reduce redundant time, materials and labor and to obtain high-quality housing.

FIG. 7 to FIG. 8 show a conventional example of a construction technique for a middle- and high-rise building which is intended to be prefabricated, and is called a unitized construction method for assembling a dwelling unit.

In the unit chemical construction method shown in FIG. 7, a dwelling unit 2 assembled in a box shape is inserted into a space frame 1 mainly composed of H-section steel, and the dwelling unit 2 is lifted by a crane 3. It is placed on the lifting plate 4 serving also as a pushing jig, is exposed to the insertion portion 1 a of the space frame 1, and is inserted into the insertion portion 1 a by an insertion device provided on the lifting plate 4.

The unitized construction method shown in FIG. 8 is a method in which steel-frame space units (dwelling unit) 5 are piled up on site by a crane 6, and is also called a block construction method. In addition, the space unit 5 that can be piled up on site is the frontage 3,150, the depth 11,
270, height 2,670, weight 9-10t as standard, the column direction is ramen, the span direction is multi-column type fieldend truss structure, the outer wall of the unit is The curtain wall made of steel plate is pre-installed at the factory, and the sash and glass are also installed at the factory.

Here, the dwelling unit 2 and the space unit 5 are basically of a box type of a rectangular box as a whole as shown in FIG. 9, and the column portions 7 standing at the four corners and these columns are provided. An upper beam portion 8a and a lower beam portion 8b which are bridged between the upper and lower ends of the unit 7 and serve as a framework for the upper and lower portions of the unit, and a ceiling body 9a and a floor arranged on the upper and lower surfaces of the six faces of the unit. The main body is a body (not shown), and walls 9c respectively provided on the side surfaces facing the outer surface of the building.

[0008]

By the way, the dwelling unit used in the above-mentioned unitized construction method has the following disadvantages. When building a building by stacking the dwelling unit 2 (5) as shown in FIG. 7 or 8,
In order to improve the strength against vertical load and horizontal load, the structure of each individual dwelling unit must be strengthened. Especially, when the number of floors increases and the number of layers increases, the dwelling unit placed in a lower layer can withstand the vertical load. It is necessary to further increase the structural strength. Then, in order to increase the structural strength of the dwelling unit unit against a vertical load, it is conceivable to increase the cross section of the pillar portion that normally forms the dwelling unit unit.

However, when the cross section of the pillar is enlarged, the cross section of FIG.
As shown in 0, the projected corners P are formed at the four corners of the living space A formed inside the frame, and the inner dimension L between the pillars is reduced accordingly, so it should be assembled to the dwelling unit. There is an inconvenience that the interior members such as furniture cannot fit and the interior members cannot be shared.

The present invention has been proposed in view of the above circumstances. An object of the present invention is to provide a common interior member that has sufficient structural strength against a vertical load and is to be assembled in a dwelling unit. The purpose is to provide a dwelling unit that can do this.

[0011]

In the dwelling unit of the present invention, the pillar portion is formed of a steel material having an L-shaped horizontal cross section, and the L-shaped steel material is arranged so that its inner corner side faces the frame. A plurality of horizontal middle beams between the upper beam portion and the lower beam portion and between the pillar portions that form the wall surface of the dwelling unit.
Part, the end part is fixed to the inner corner side of the pillar part in an L shape
Arranging in this state was the means for solving the above problems.

[0012]

According to the present invention, the strength of the pillar is increased by forming the pillar with a steel material having an L-shaped horizontal cross section and arranging the steel material so that its inner corner side faces the frame. Even if the thickness of the steel material is increased as much as possible, since the thickness is sufficiently smaller than the thickness of the wall body, there is almost no effect on the volume of the living space formed in the frame. In addition, a plurality of middle beams are horizontally arranged between the pillars that form the wall surface of the dwelling unit , and the end portions of these middle beams are inside the pillar.
By being fixed to the corner side in an L-shape, the strength of the pillar portion itself and the strength between the pillar portions is increased, and the earthquake resistance of the entire dwelling unit is improved. The strength of the wall body is increased by connecting the wall body to these mid-beam portions, and it is possible to sufficiently resist horizontal force (horizontal load) such as an earthquake.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing an embodiment of a dwelling unit according to the present invention. In this figure, reference numeral 10 is a dwelling unit. This dwelling unit 10 has four pillars 11 ...
And an upper beam portion 12 that connects the upper ends of the pillar portions 11 and a lower beam portion 13 that connects the lower ends of the pillar portions 11 to a rectangular parallelepiped box-shaped frame structure, A ceiling body (not shown) and a floor body (not shown) serving as upper and lower surfaces of the frame, and a wall body 16 forming an outer surface of the building are provided, and the interior of the frame serves as a living space A. . Here, the pillar portion 11 ..., the upper beam portion 12, ..., The lower beam portion 13
Are connected to each other by pin joining or the like, but by being reinforced by the wall body 16 as described later, the dwelling unit 10 has sufficient strength.

The column portion 11 is made of an L-angle steel material and mainly resists a vertical force (vertical load), and its inner corner side 11a is arranged toward the living space A, In addition, the outside corner side 11b is arranged so as to substantially coincide with the corner portion of the dwelling unit 10. Further, a plurality of horizontal mid-beam portions 1 are provided between the pillar portions 11 forming the wall surface.
7 has an L-shaped end portion on the inner corner side 11a of the pillar 11.
It is attached in the state of being fixed to the
7 ... A wall 16 is attached on the upper side (outer surface side of the dwelling unit 10). The wall body 16 is made of a steel plate having a sufficient strength, and is wholly made into an earthquake resistant wall by being connected to the middle beam portions 17 ... Further, the wall unit 16 configured as such an earthquake-resistant wall allows the dwelling unit 10 to sufficiently withstand a horizontal force (horizontal load) such as an earthquake.

Here, the thickness of the steel material forming the pillar portion 11 is appropriately selected depending on the arrangement position of the dwelling unit units 10, that is, the layer position in a middle-high-rise building formed by stacking a large number of dwelling unit units 10. It For example, the dwelling unit unit 10 arranged in the uppermost layer does not need to have higher structural strength than the dwelling unit unit arranged in the lower layer because the degree of receiving a vertical load is small, while the dwelling unit unit arranged in the lowermost layer is In No. 10, since the degree of receiving the vertical load is the highest, it is necessary to make the structural strength sufficiently higher than that of the dwelling unit arranged in the upper layer. In order to increase the structural strength of the dwelling unit 10, as shown by the solid line in FIG. 2, the thickness of the steel material forming the pillar portion 11 is increased, and in order to decrease the structural strength, two points in FIG. It is only necessary to reduce the thickness of the steel material as shown by the chain line. In this case, even if the thickness of the steel material is made sufficiently thick as shown by the solid line in FIG. 2 to increase the structural strength, it will be sufficiently thinner than the thickness of the upper beam body 12 and the wall body 16, and therefore As described above, by increasing the area of the pillar portion to increase the structural strength, the disadvantage that the living space A is narrowed can be avoided.

Further, a large number of beam portions 18 are spanned between the lower beam portions 13 of the dwelling unit 10, and the lightweight concrete is formed after the dwell unit 10 is assembled on the beam portions 18. Floor materials such as the above are fixed to form the floor body 14. Further, a stud 19 is installed between the upper beam portion 12 and the lower beam portion 13 having a long length. The studs 19 are made of a steel material having a T-shaped horizontal cross section, and are made of a pillar portion 11 and a wall body 1.
6 and 6 bear the load applied to the dwelling unit 10.

Next, an example of a middle-high-rise building using such a dwelling unit 10 will be shown. FIG. 3 shows an example of a middle-high-rise building constructed using a dwelling unit, and reference numeral 21 in FIG. 3 is a middle-high-rise building. This middle and high-rise building 21
Is formed by combining the dwelling unit 10 shown in FIG. 1 and the conventional dwelling unit 2 shown in FIG.
Each of the dwelling unit units 10, 2, ... Is sequentially stacked on the foundation 22. Here, middle and high-rise buildings 21
, The same type of dwelling unit 10 ... (2
…) Can be stacked directly above it. As for the dwelling unit 10 ... As described above, the thickness of the steel material forming the pillar portion 11 of the dwelling unit unit 10 in the lowermost layer is the thickest, and as it goes above this, the thickness of the steel material of the pillar portion 11 increases. It is constructed and arranged to be thin.

In this case, the upper and lower dwelling unit units 10, 1
The pillar portion 11 and the pillar portion 11 are connected to each other between 0 positions by welding in place or a connecting tool such as a bolt. As for the dwelling unit 2 ..., it is also possible to use the wall body 9c of the lowest dwelling unit 2 having the highest strength, and to use the wall body 9c of progressively lower strength as it goes above this. it can.

As the arrangement in the plane of the middle-high-rise building 21, for example, the dwelling unit units 10 are arranged at four corners as shown in FIG. 4, and the vertical load applied to the whole middle-high-rise building 21 in these dwelling unit units 10. It is also preferable to carry most of the horizontal load.
Further, it is preferable to use the dwelling unit 10 also in a portion of the middle-high-rise building 21 that protrudes outward, that is, a portion such as a staircase and an elevator as shown by B in FIG. 4, and in that case, the dwelling unit unit shown in FIG. A staircase, an elevator, etc. may be installed in the frame having the basic structure of 10. When the dwelling unit 10 and the dwelling unit 2 are joined in the arrangement as shown in FIG. 4, the connection between the dwelling unit 10 and the dwelling unit 2 at the portion indicated by C in FIG. 4 is as shown in FIGS. 5 and 6. Is performed through the connecting hardware 23.

The connecting metal piece 23 is an L-shaped plate body in which one corner of a square plate is cut out, and the remaining corner is obliquely cut. From each side formed by cutting. It is a steel plate having a hole 24 ... Formed slightly inside to insert a connecting tool such as a bolt. In the connecting hardware 23, the recess 22a formed by cutting out the corner is engaged with the outer surface side of the pillar 11 of the dwelling unit 10 as shown in FIGS. 5 and 6, and the recess 22a is formed. Rectangular plate-shaped tongue piece 2 whose side extends outwardly at the upper end on the outer surface side of the pillar portion 11
0, 20 are mounted on the upper surface side, and are connected to the dwelling unit 10 by inserting and fastening a connecting tool between the holes 24 ... And a connecting hole (not shown) formed in the tongue piece 20 in advance.

Other than the recessed portion 22a, the oblique side portions 22b formed by cutting the corner portions are sandwiched between the dwelling unit units 2 and 2 arranged vertically as shown in FIG. 6, and It is sandwiched between the lower beam portion 8b of the upper housing unit 2 and the upper beam portion 8a of the lower housing unit 2.
Then, a hole (not shown) formed in the lower beam portion 8b, the hole 24 in the vicinity of the oblique side portion 22b, and a hole (not shown) formed in the upper beam portion 8a are passed through to connect bolts or the like. When the tool is inserted and fastened, the connecting hardware 23 is sandwiched between the dwelling unit units 2 and 2.

Then, under such a structure, C in FIG.
The connection between the dwelling unit units 10 and the dwelling unit units 2 at the portion indicated by is such that the dwelling unit units 2 lean against the dwelling unit unit 10 via the connecting hardware 23. Therefore, by increasing the thickness of the steel material forming the pillar portion 11 of the dwelling unit 10 to sufficiently increase the structural strength of the dwelling unit 10, the structural strength of the dwelling unit 2 ... Can also be increased. That is, the dwelling unit 10
Part of the load applied to the dwelling unit 2, ...
You will be able to carry it through.

Therefore, in the middle-high-rise building 21 having such a structure, the dwelling unit unit row in which the dwelling unit units 10 are vertically stacked acts as a pillar of the entire building 21 and the load applied to the entire building 21. To fight against. That is, the horizontal force applied to the building 21 is transmitted to the dwelling unit units 10 at the four corners where the rigidity is strengthened, and the horizontal force is borne in this portion, so that it is necessary to place a heavy load on the other dwelling unit units 2 in terms of structural design. Disappears. From this fact, the strength required for the members constituting the dwelling unit 10 may be relatively small, and therefore, the middle-high-rise building 21 as a whole becomes an inexpensive building.

In addition, in the middle-high-rise building 21 shown in FIGS. 3 and 4, the dwelling unit units 10 and 1 are provided on the upper part of the roof.
The rigidity of the whole can be improved by connecting 0s with beams. Also, the strengthened dwelling unit 10, ...
The arrangement of 2 ... Is not limited to the arrangement of FIG. 4, and various arrangements according to the form of the building can be adopted.

In the dwelling unit 10 having such a structure, the pillar portion 11 is made of a steel material having an L-shaped horizontal cross section, and the steel material is arranged so that its inner corner side faces the frame. However, even if the thickness of the steel material is increased to increase the strength of the pillar portion 11, the thickness is sufficiently smaller than the thickness of the upper beam portion 12, the lower beam portion 13 and the wall body 16, so that the residence formed in the frame It does not reduce the volume of space.
And when constructing the middle-high-rise building 21 using such a dwelling unit 10, the steel material of the pillar part 11 of the dwelling unit 10 of the lower layer which receives more vertical load is thickened in order to make structural strength suitable. Therefore, they can be easily stacked in the middle and high layers without being greatly restricted in strength. In addition, since the volume of the living space does not change (decrease) even if the thickness of the steel material is changed (thickened), it is possible to commonly use unit furniture having a predetermined size. In other words, when the area of the pillars with a square cross section is increased to increase the structural strength of the middle and high-rise unit units as in the past, some of them protrude into the living room space and the space between the pillars is increased. It is possible to eliminate the inconvenience that the unit furniture becomes narrower and the unit furniture standardized to a predetermined size cannot be assembled. Also,
A plurality of middle beam parts 17 are horizontally arranged between the pillar parts 11 forming the wall surface of the dwelling unit 10 , and
The end portion of the beam portion 17 is L-shaped on the inner corner side 11a of the column portion 11.
By being fixed to the pillar portion 11 and the pillar portion 1
The strength between 1 and 11 can be increased, and the dwelling unit 1
The overall seismic resistance can be improved. Then, by attaching the wall body 16 to these mid-beam portions 17, it is possible to increase the strength of the wall body 16 and sufficiently resist the horizontal force (horizontal load) such as an earthquake.

In the above embodiment, the dwelling unit 10 is used.
The above is configured by only a so-called frame, but it goes without saying that an interior member such as a bus unit, a sanitary unit, and partition furniture may be assembled in advance inside the dwelling unit 10. Further, as the dwelling unit 10, only the frame of the building is schematically shown, but it goes without saying that each dwelling unit 10 is coated with fireproof coating or the like.

[0027]

As described above, in the dwelling unit of the present invention, the pillar portion is formed of a steel material having an L-shaped horizontal cross section, and the L-shaped steel material is arranged so that its inner corner side faces the frame. Since it has been installed, even if the thickness of the steel material is increased to increase the strength of the column, it will be sufficiently thinner than the thickness of the upper beam part, the lower beam part and the wall body, and therefore the residence formed in the frame. It does not reduce the volume of space. And
When constructing a middle-high-rise building using such dwelling unit, in order to obtain appropriate structural strength, it suffices to simply thicken the steel material of the pillar of the lower dwelling unit that receives more vertical load. It can be easily stacked in the middle and high rises without the above-mentioned large restrictions. Moreover, since the volume of the living space does not change (decrease) even if the thickness of the steel material is changed (thickened), it is possible to put all interior members such as unit furniture in common, and therefore Workability such as carrying in is improved, and the cost of the entire building can be reduced. In addition, a plurality of middle beams are horizontally arranged between the pillars that form the wall surface of the dwelling unit , and the end portions of these middle beams are inside the pillar.
By being fixed to the corner side in an L shape, the strength of the pillars themselves and the strength between the pillars can be increased, and the earthquake resistance of the entire dwelling unit can be improved. Then, by attaching a wall body to these mid-beam portions, the strength of the wall body can be increased, and it is possible to sufficiently resist horizontal force (horizontal load) such as an earthquake.
