Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dwelling unit used for constructing middle and high-rise buildings, and more particularly to a connecting structure between dwelling unit.

[0002]

2. Description of the Related Art In recent years, due to the shortage of land in large cities and the exhaustion of the required number of houses, in urban apartments, high-rise apartments of 10 to 15 floors are constructed. It's coming.

Generally, these are SRC constructions whose pillars are mainly H-shaped steels, large columns of steel plates with integrated steel beams and wall parts, beams of perimeter walls with PCs with beam braces, floors of floors. It was made on-site and basically applied the conventional construction technology for office buildings. By the way, even in this type of multi-dwelling house, prefabricated houses such as detached houses are being promoted in order to reduce time, materials and labor costs and to obtain high quality houses.

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 unitized construction method shown in FIG. 7, a housing unit 2 assembled in a box shape is inserted into a space frame 1 mainly composed of H-shaped steel, and the housing unit 2 is lifted by a crane 3. It is placed on the 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 the 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 stacked on the site has a frontage of 3,150 mm , a depth of 11,270 mm , a height of 2,670 mm , and a weight of 9 to 10.
With t as the standard, the frame direction is a rigid frame, and the span direction is a multi-column type Fieldendale truss structure. The outer wall of the unit is a curtain wall made of steel-resistant steel plate, which is pre-installed at the factory. In addition, sashes and glass are also being 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 inventor, as a result of earnest research in view of the above circumstances, has four pillars formed of a steel material having an L-shaped horizontal cross section, and an upper beam portion connecting the upper ends of these pillars, respectively. A housing unit that forms a living space inside a frame composed of a lower beam part that connects the lower ends of the pillar parts, and an L-shaped steel material forming the pillar part is arranged so that its inner corner side faces the inside of the frame structure. He invented a rectangular parallelepiped housing unit. That is, according to such a dwelling unit, even if the thickness of the steel material is increased in order to increase the strength of the pillar portion, the thickness is sufficiently smaller than the thickness of the wall body, so that the volume of the living space formed in the frame is increased. The effect on the interior is almost eliminated, and it becomes possible to standardize the interior members such as furniture units to be assembled in the dwelling unit.

However, in such a dwelling unit, when it is used to construct a high-rise building or the like,
The connection between the dwelling unit units, particularly the connection with the conventional dwelling unit units, becomes a more concrete technical requirement, and the provision thereof is urgent.

The present invention has been proposed in view of the above circumstances, and 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 to a dwelling unit. It is to provide a dwelling unit unit that can be used, and to provide a connection structure between this dwelling unit unit and a conventional dwelling unit unit.

[0013]

In the connection structure between dwelling unit units of the present invention, one first dwelling unit unit and a second dwelling unit unit are provided.
Three dwelling unit units are arranged so that one corner of each of them is close to each other, and an outwardly extending tongue piece is formed at an upper end portion or a lower end portion of the first pillar portion, and the tongue piece has a plate shape. The connection hardware is fixed, and the connection hardware is fixed to the upper surface or the lower surface of the corner of each of the three second dwelling unit units.

[0014]

According to the connection structure between the dwelling unit units of the present invention,
One first dwelling unit and three second dwelling units are arranged with one corner of each being close to each other, and these dwelling unit are connected and fixed via the tongue piece and the connecting hardware, The second dwelling unit is connected in such a manner that it leans against the first dwelling unit via the connecting hardware.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, prior to explaining a connecting structure between dwelling unit units according to the present invention, a first dwelling unit as a constituent element of the connecting structure will be described.

The frame includes a frame assembled in a mold, a ceiling body (not shown) and floors (not shown) that are upper and lower surfaces of the frame, and a wall 16 forming an outer surface of the building. Is a living space A. Here, the pillar portions 11, ..., The upper beam portions 12, ..., The lower beam portions 13, ... Are connected by pin joining or the like, but the first dwelling unit 10 is reinforced by being reinforced by the wall body 16 as described later. It has sufficient strength.

The pillar portion 11 is formed of an L-angle steel material and mainly resists a vertical force (vertical load), and its inner corner 11a side is arranged toward the living space A, and The outer corner side 11b is arranged so as to substantially coincide with the corner portion of the first dwelling unit 10. In addition, a plurality of middle beam portions 17 are horizontally attached between the pillar portions 11 forming the wall surfaces, and above these middle beam portions 17 ... (Outer surface side of the first dwelling unit 10). The wall body 16 is attached. 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 ... The first housing unit 10 sufficiently resists a horizontal force (horizontal load) such as an earthquake due to the wall body 16 which is an earthquake resistant wall.

The steel material forming the pillar portion 11 is the first steel material.
The thickness is appropriately selected depending on the arrangement position of the dwelling unit unit 10, that is, the layer position in a middle-high-rise building formed by stacking a large number of dwelling unit units. For example, in the first dwelling unit 10 arranged in the uppermost layer,
Since the degree of receiving the vertical load is small, it is not necessary to increase the structural strength of the first dwelling unit unit arranged in the lower layer, while the first dwelling unit unit 10 arranged in the lowermost layer can reduce the vertical load. Since the degree of receiving it is the highest, it is necessary to make its structural strength sufficiently higher than that of the first dwelling unit that is arranged above it. And the first

As indicated by the solid line, the thickness of the steel material forming the pillar portion 11 is increased, and in order to reduce the structural strength, the thickness of the steel material may be decreased as indicated by the chain double-dashed line in FIG. In this case, even if the thickness of the steel material is made sufficiently thick as shown by the solid line in FIG. 2 in order to increase the structural strength, it becomes sufficiently thinner than the thickness of the upper beam portion 12 and the wall body 16, and therefore the conventional As described above, by increasing the area of the pillar portion to increase the structural strength, the disadvantage that the living space is narrowed can be avoided.

The lower beam portion 1 of the first dwelling unit 10
A large number of beam portions 18 are laid across the space 3. The floor members such as lightweight concrete are fixed on the beam portions 18 after assembling the first dwelling unit 10 ... A body 14 is formed. Further, a stud 19 is installed between the upper beam portion 12 and the lower beam portion 13 having a long length. The stud 19 is made of a steel material having a T-shaped horizontal cross section, and bears a load applied to the dwelling unit 10 together with the pillar 11 and the wall 16. Further, as the second dwelling unit, which is a component of the connection structure between dwelling unit units of the present invention,
For example, the dwelling unit 2 shown in FIG. 9 is used.

Next, such a first dwelling unit 10
A middle-high-rise building constructed from the second dwelling unit 2 will be described with reference to FIG. Reference numeral 21 in FIG. 3 is a middle-high-rise building, and this middle-high-rise building 21 is a foundation 2
The first dwelling unit units 10 and the second dwelling unit units 2 are sequentially stacked on the second unit. Here, in the middle-high-rise building 21, the dwelling unit units 1 of the same type are used.
0 ... (2 ...) are sequentially stacked immediately above. 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 for the arrangement in the plane of the middle-to-high-rise building 21, for example, the first dwelling unit units 10 are arranged at four corners as shown in FIG. 4, and the middle-to-high-rise buildings are arranged in the first dwelling unit units 10. It is preferable to carry most of the vertical load and the horizontal load applied to the whole 21. 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. 1
A staircase, an elevator, etc. may be installed in the frame having the basic structure of 0.

Next, the connecting structure between the dwelling unit units of the present invention will be described. As shown in FIG. 4C, this connection structure is a structure showing a connection state in a portion where one first dwelling unit and three second dwelling units are arranged with one corner of each of them being in close proximity. is there. Such first
The connection between the dwelling unit unit 10 and the second dwelling unit 2 ... Is made through a connecting metal piece 23 as shown in FIGS. 5 and 6.

The connecting hardware 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. And, as for this connecting hardware 23, the recessed portion 22a formed by notching the corner portion is engaged with the outer surface side of the pillar portion 11 of the first dwelling unit 10 as shown in FIGS. 5 and 6, and The recessed portion 22a side is placed on the upper surface side of the rectangular plate-shaped tongue pieces 20 and 20 formed to extend outward at the outer surface side upper end portion of the column portion 11, and the holes 24 are connected to the tongue piece 20 in advance. A connecting tool is inserted into and fastened to the hole (not shown) to be connected and fixed to the first dwelling unit 10.

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 and fixed between the dwelling unit units 2 and 2.

The structural strength of the dwelling unit 2 can be increased. That is, the first dwelling unit 10
It is possible to bear a part of the load applied to the second dwelling unit 2 via the connecting hardware 23.

Therefore, in the middle-high-rise building 21 constructed by such a connecting structure, the dwelling unit unit row in which the first dwelling unit units 10 are vertically stacked acts as a pillar of the entire building 21. However, the load applied to the entire building 21 is resisted. That is, the horizontal force applied to the building 21 is transmitted to the first dwelling unit 10 at the four corners where the rigidity is strengthened, and the horizontal force is borne by this portion, so that the structural design of the other second dwelling unit 2 is performed. There is no need to put a heavy burden on top. From this fact, the strength required for the members constituting the first dwelling unit 10 may be relatively small, and therefore, the middle-high-rise building 21 as a whole becomes an inexpensive building.

In the above embodiment, the tongue piece 20 is formed on the upper end portion of the pillar portion 11 in the first dwelling unit 10, but the tongue piece 20 may be formed on the lower end portion of the pillar portion 11. Of course. In addition, in the middle-high-rise building 21 shown in FIGS. 3 and 4, the dwelling unit 1 is installed at the upper part of the roof.
By connecting 0 and 10 with beams, the overall rigidity can be increased. Further, the arrangement of the reinforced dwelling unit units 10, ..., 2 is not limited to the arrangement shown in FIG. 4, and various arrangements according to the form of the building can be adopted.

In the connecting structure between the dwelling unit units 10 and the dwelling unit units 2 having such a structure, the second dwelling unit units 2 ... Lean on the first dwelling unit unit 10 via the connecting hardware 23, respectively. Since it is in a state, the thickness of the steel material forming the pillar portion 11 of the first dwelling unit 10 is made sufficiently thick, and the structural strength of the first dwelling unit 10 is increased so that the first dwelling unit 10 is connected to the pillar 11 by means of the connecting hardware 23. The structural strength of the second dwelling unit 2, ... In addition, in the first dwelling unit 10 used in this connection structure, even if the thickness of the steel material is increased to increase the strength of the column portion 11, the upper beam portion 12, the lower beam portion 13 and the wall body 16 are provided.
Since it is sufficiently thinner than the thickness of the housing, the volume of the living space formed in the frame is not reduced, and therefore all interior members such as unit furniture can be put in common.

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.
