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-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.

[0004] Therefore, the applicant of the present invention is a construction method mainly used for low-rise buildings, which is a unitized construction method for constructing a building by stacking box-type dwelling unit units manufactured in advance in a factory or the like. We have proposed a structure of a high-rise building and a construction method thereof (Japanese Patent Application No. 3-115511) which can be applied to a high-rise building at low cost.

As shown in FIG. 4, the structure of this middle-high-rise building and its construction method are as follows. The dwelling unit units 1 and 2 constituting each floor of the building are stacked on the dwelling unit units 1 and 2, and the dwelling unit units 1 and 2 that are adjacent to each other in the front, rear, left, right, and top are connected to each other.

On each floor of the building, at least one reinforced dwelling unit unit 2 whose rigidity is reinforced to receive a vertical load is arranged, and the reinforced dwelling unit units 2 are vertically arranged. It is to be installed continuously.

Further, the dwelling unit 1, 2 has four pillars 1a, 2a, and upper beam portions 1b, 2b and lower beam portions 1c, 2c for connecting the upper and lower ends of these pillars 1a, 2a, respectively. It becomes a box type by and, and
The reinforced dwelling unit unit 2 having the reinforced rigidity 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.

Among 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 a vertical force. Since it can be constructed, the vertical force applied to the building can be transmitted to the row of the reinforced dwelling unit units 2 with the most rigidity, and the vertical force can be borne by this portion, so that the vertical force applied to the building is increased. It does not impose a heavy burden on 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 unit type building as described above, if the number of dwelling unit units on each floor is relatively large, that is, the building area is large, one building is There is a construction method in which it is divided into dwelling unit units (hereinafter simply referred to as “unit units”), one unit unit is constructed, and then other unit units are sequentially constructed by connecting to it. May be This is because the crane for hoisting the dwelling unit can be placed on the site for constructing the building except when constructing the final unit assembly, so by arranging the crane etc. outside the site. This is because it is possible to avoid traffic obstruction as much as possible.

However, in the above-mentioned middle- and high-rise building, the adjacent dwelling unit units are conventionally separated from each other by, for example, four dwelling unit units which are adjacent to each other in the front, rear, left and right directions.
At the center of the dwelling unit unit of the door, four pillars adjacent to each other are connected by a substantially square connecting metal piece that integrally covers the upper surfaces of the pillars. Moreover, this connecting hardware is sandwiched between the dwelling unit units connected vertically.

Therefore, in the unit assembly to be constructed first, it is necessary to extend the above-mentioned connecting hardware from the dwelling unit arranged at the connection portion of this unit assembly with another unit assembly. . In this case, the extended connection hardware is in a state of being sandwiched between the upper and lower dwelling unit units of the previously assembled unit assembly,
It needs to be sandwiched between the upper and lower dwelling unit units of the unit assembly to be constructed later. Therefore, the front part of the connecting metal piece that extends from the unit assembly that was built first is extended to the inside of the position where the housing unit of the unit assembly that will be built later is arranged.

Therefore, when the dwelling unit of the unit assembly to be constructed later is hoisted and installed by a crane or the like, the front part of the connecting hardware is obstructed. That is, it becomes very difficult to install a dwelling unit unit of a unit assembly to be constructed later adjacent to a dwelling unit unit of a unit assembly to be built first.

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 building, in which one building is divided into a plurality of unit aggregates to construct the unit. It is an object of the present invention to provide a connection structure for dwelling unit units in a unit-type building in which dwelling unit units can be easily connected between groups.

[0014]

Two or more unit aggregates formed by connecting and connecting a plurality of dwelling unit units formed in a box shape with a beam spanned between them in the front, rear, left, right, up and down are abutted and abutted. In a unit-type building in which unit aggregates are connected to each other on their opposing faces, the unit units belonging to the same unit aggregate and adjacent to each other on the same floor on the opposing face side of the dwelling unit units constituting the above-mentioned opposing face Each of the dwelling unit units, in which the pillars are connected to each other by the plate-like first connecting metal pieces that are bridged over the respective upper end portions thereof, and belong to different unit aggregates and face each other to form the opposing surface, respectively. Beam body each other facing in the opposite surface side,
Connected by the plate-shaped second connection hardware that is laid on the upper surface of each, these first and second connection hardware,
The above-mentioned problem is solved by being sandwiched between the upper and lower dwelling unit units.

[0015]

According to the above construction, first, the dwelling unit units constituting the facing surface on the side of the unit assembly (unit assembly A) constructed earlier and adjoining on the same floor are joined by the first connecting metal object. The unit assembly A is constructed in this state. Then, when the unit aggregate (unit aggregate B) to be constructed later is constructed, the second connecting hardware is connected to the unit aggregate A at the stage where the first unit of the unit aggregate B is placed. It is inserted between the beam bodies of the dwelling unit units arranged above and below the facing surface and is bridged over the beam bodies of the dwelling unit units on the first floor arranged on the facing surface of the unit assembly B. At this time, since the first connecting hardware is sandwiched between the pillars of the dwelling unit units arranged above and below the unit assembly A, the first connecting hardware is sandwiched between the beams of the dwelling unit units arranged above and below.
