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. 4, the structure and construction method of this middle-high-rise building are as follows. 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. ..

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 divided into a plurality of blocks. The building method may be taken by dividing into blocks and building each block in sequence. This is because the crane for hoisting the dwelling unit can be placed on the site for constructing the building except when the last block is being built, so placing a crane etc. outside the site will hinder traffic. Can be avoided as much as possible.

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

Therefore, in the block to be constructed first, it is necessary to extend the above-mentioned connecting hardware from the dwelling unit unit arranged at the connecting portion of the block with other blocks. In this case, the extended connecting hardware is in a state of being sandwiched between the upper and lower dwelling unit units of the block constructed earlier, and is also sandwiched between the upper and lower dwelling unit units of the block constructed later. Needs to be done. Therefore, the front part of the connecting metal piece extending from the block constructed earlier extends to the inside of the position where the housing unit of the block constructed later is arranged.

Therefore, when the housing unit of the block to be constructed later is hoisted and installed by a crane or the like, it is obstructed by the front part of the connecting hardware. That is,
It is very difficult to install a block unit to be constructed later.

The present invention has been made in view of the above circumstances. An object of the present invention is to construct a unit type building by dividing one building into a plurality of blocks. 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.
