Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention combines at least two types of dwelling unit units constituting a dwelling unit of a building by arranging them in rows in the up-down direction, and arranging them in a plurality of rows in the front-rear, left-right and up-down directions. The present invention relates to a structure of a middle and high-rise building in which units are integrated with each other.

[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, for example, middle to high-rise apartments of 10 to 15 floors have been constructed. It's coming.

Generally, these are SRC constructions whose pillars are mainly H-section steels, the columns are large PC boards in which the steel beams and walls are integrated, the boundary walls are PC boards with beam braces, and the floor is It was done on site and basically applied the conventional construction technology for office buildings. By the way, even in this type of multi-dwelling houses, prefabricated houses such as detached houses are being promoted in order to reduce the cost of time, materials and labor and to obtain high quality houses.

Therefore, the applicant of the present invention is a construction method mainly used for low-rise buildings, in which a unitized construction method for constructing a building by stacking box-type dwelling unit units manufactured in advance in a factory or the like is used. We have proposed a structure of a middle-high-rise building and a construction method thereof (Japanese Patent Application No. 3-115511) that can be applied to a middle-high-rise building at low cost.

As shown in FIG. 5, the structure of this middle-high-rise building and its construction method are as follows. A plurality of dwelling unit units 1 and 2 forming a dwelling unit on the first floor are arranged on the first floor of the building in front, rear, left and right, The dwelling unit units 1 and 2 forming the respective floors of the building are stacked on the dwelling unit units 1 and 2, and the dwelling unit units 1 and 2 adjacent to each other in the front, rear, left, right, and top are integrated with each other.

On each floor of the building, at least one reinforced dwelling unit unit 2 having a reinforced rigidity so as to bear a horizontal load is arranged, and these reinforced dwelling unit units 2 are vertically arranged. It is to be installed continuously.

Further, the dwelling unit units 1 and 2 include four pillars 1a and 2a, and upper and lower beam portions 1b and 2b and lower beam portions 1c and 2c which connect the upper and lower ends of these pillars 1a and 2a, respectively. It becomes a box type by and, and
The reinforced dwelling unit unit 2 of which the rigidity is strengthened among the dwelling unit units 1 and 2 is one in which a rigidity strengthening member such as a bearing wall is incorporated into at least two adjacent faces of the front, rear, left, right, and top six faces.

In the dwelling unit units 1 and 2 constituting the building, the row of the reinforced dwelling unit units 2 in which the reinforced dwelling unit units 2 are stacked has a frame structure in which the rigidity of the building is increased against horizontal force. Since it can be constructed, the horizontal force applied to the building can be transmitted to the row of the reinforced dwelling unit units 2 with the highest rigidity, and the horizontal force can be borne in this part, so that the horizontal force applied to the building is increased. It does not impose a heavy burden on the other dwelling unit units 1 in terms of structural design, and the strength required for the members constituting the dwelling unit unit 1 can be small, so that an inexpensive building as a whole structure can be constructed. ..

[0009]

By the way, in the above-mentioned conventional middle-high-rise building, since the reinforced dwelling unit unit bears the main horizontal force for the vertical joining of dwelling unit units other than the reinforced dwelling unit unit, It is not always necessary to make a rigid joint such as welding. Therefore, upper and lower dwelling unit units may be connected with bolts so that they can be used in low-rise unit-type buildings, etc. Conditions such as workability and strengthening of rigidity against the force applied in the vertical direction must be taken into consideration.

Further, as a structure of a dwelling unit unit in which columns and beams are assembled in a box type, a prismatic cylindrical body is provided at a joint portion of columns and beams between two substantially square plate bodies arranged in parallel. It is known to use a diaphragm sandwiching. In this structure, a box-shaped unit is constructed by joining an end of a column made of a prismatic steel pipe and a plate of a diaphragm and a beam member to a side surface of a cylinder of the diaphragm. It is a thing. Further, the dwelling unit units are constructed by joining diaphragm plates together with bolts.

However, in the prismatic diaphragm described above, an opening for bolt operation when the plates are bolted together is required on either side of the cylindrical body of the diaphragm to be joined vertically. Since beam members are joined to two side surfaces of the four side surfaces of the cylindrical body of the columnar diaphragm, that is, the side surfaces where the diaphragms arranged at the four corners of the ceiling or floor of the dwelling unit are opposed to each other, the above operation is performed. No opening can be provided.

Further, since the other two side surfaces of the diaphragm face the outer surface side of the dwelling unit, if an opening for bolt operation is provided on this side, the partition is already formed on the outer peripheral surface of the dwell unit. When a wall or the like is installed, it is necessary to connect the dwelling unit units from the outside of the dwelling unit unit, which is not suitable for work in high places.

Further, it is possible to provide an opening for operation at the corner portion of the diaphragm facing the center of gravity of the dwelling unit, without being disturbed by the beam member, and at the corner portion. If the opening is provided, the upper and lower dwelling unit units can be connected to each other in the dwelling unit unit.
However, when an opening, that is, a cutout, is provided at the corner of a prismatic cylinder, the strength of the prism against a vertical load is significantly reduced, and the unit for a middle-high-rise building where the vertical load becomes large. Not suitable as a unit.

When vertically connecting the dwelling unit units using the above diaphragms, the beam members are not joined to each other but the beam members are joined to each other so that the upper and lower dwelling unit units are joined together. It is possible to join them, but the vertical load is applied to the pillars, but the pillars are not joined vertically,
It is not suitable for middle- and high-rise houses with a large vertical load compared to low-rise buildings.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a unit type middle-high-rise building in which reinforced dwelling unit units are vertically arranged in a column shape, and An upper and lower connection part is to provide a structure of a middle-high-rise building which is excellent in connection work at a high place and has strength against a load in the vertical direction.

[0016]

The structure of a middle- and high-rise building according to the present invention has a structure in which at least two types of dwelling unit units constituting a dwelling unit of a building are combined in each row in the vertical direction and a plurality of rows are arranged in the front, rear, left and right, Each of the dwelling unit units that are adjacent to each other in the front-rear, left-right, and up-down directions is integrated with each other.
The rigidity of the dwelling unit unit is stronger than that of the dwelling unit unit, and the first dwelling unit units arranged in the vertical direction are joined by welding, and the second dwelling unit units arranged in the vertical direction are bolted to each other.

Further, at least two types of dwelling unit units constituting a dwelling unit of a building are combined for each row in the vertical direction and arranged in a plurality of rows in the front, rear, left and right, and the adjacent dwelling unit units in the front, rear, left, right and up are integrated with each other. And a first dwelling unit that forms at least one row along the up-and-down direction of the dwelling unit arranged in a plurality of rows in the front-rear, left-right, and up-down directions, and a portion of the building other than the first dwell-unit unit. And a second dwelling unit constituting the
The dwelling unit unit is made up of a column body and an upper beam portion and a lower beam portion that connect the upper and lower ends of these column bodies to each other in a box shape, and at least the front, rear, left, right, up, and down six faces are adjacent to each other. The two dwelling units have rigidity-enhancing members such as load-bearing walls incorporated therein to enhance the rigidity in order to bear the load in the horizontal direction of the building, and the second dwelling unit includes a pillar and A second dwelling unit that is assembled in a box shape by an upper beam part and a lower beam part that connect the upper end and the lower end of the pillar, respectively, and is vertically adjacent to the upper and lower parts of the pillar of the second dwelling unit, respectively. The provision of a diaphragm for connecting the units by bolts is a means for solving the above problems.

[0018]

According to the above construction, the row of the first dwelling unit units, which form at least one row along the vertical direction and have increased rigidity, form a frame that is rigid against horizontal force and is applied to the building. Since the horizontal force can be taken care of, it is possible to reduce the strength required for the connecting portion between the second dwelling unit and the upper and lower second units.
Therefore, it is not necessary to reinforce even if the second units arranged above and below are connected by bolt connection. Also,
By making the diaphragm used for joining the upper and lower parts of the second dwelling unit a cylindrical shape, no matter where on the side surface of the diaphragm the work opening for bolt operation is provided, the opening is formed at the corner of the prismatic prismatic shape. The work opening may be provided, for example, in a portion facing the center of gravity of the dwelling unit on the side surface of the diaphragm without causing a large decrease in strength as compared with the case where the work opening is provided.
