In this building, the building units and building units to be phase-joined are joined so that their columns correspond to each other, and the load is transmitted between the building units around the columns. There is. This is to transfer the horizontal load (wind pressure, seismic force) acting on one surface of the building between the units through the above-mentioned pillars that have the highest strength and rigidity in each building unit, and then distribute them throughout the building. The purpose of this is to prevent a localized concentrated load on a part of the building and the resulting deformation.

However, when promoting the diversification of the appearance and functions of buildings, the building units and building units that are joined together are not arranged so that their columns correspond to each other, but these columns are arranged at a considerable distance from each other. A request was made to build the building by placing it apart. In this building, in the middle part of the ceiling beam which constitutes one building unit to be phase-joined,
The upper ends of the pillars that make up the other building unit will be arranged correspondingly.

[Problems to be Solved by the Invention] However, in a building in which the upper end of the pillar of the other building unit is arranged correspondingly to the middle portion of the ceiling beam of one building unit as described above, the horizontal load between both building units is Transmission takes place between the middle part of the corresponding ceiling beam and the upper end of the column. For this reason, localized concentrated load and deformation due to the localized concentrated load occur in the middle portion of the ceiling beam having relatively low strength and rigidity, which is not appropriate.

In order to diversify the appearance, functions, etc. of the building, the present invention is directed to constructing a building unit in which the upper end of a pillar that constitutes the partner building unit to be phase-joined is arranged corresponding to the middle portion of its own ceiling beam. An object of the present invention is to reliably reinforce the ceiling beam, prevent a localized concentrated load on the ceiling beam and deformation due to the localized concentrated load, and improve construction workability for this reinforcement.

[Means for Solving the Problems] The present invention relates to a main joint portion and a main joint portion in a reinforcing structure of a building unit configured by box-shaped frames of four floor beams, ceiling beams and columns. A T-shaped reinforcing structure is used with a relay connecting part connected to the intermediate part of the connecting part, and both ends of the main connecting part forming the reinforcing structure are connected to the respective intermediate parts of opposite ceiling beams. In addition to fixing to the main attachment member, the free end portion of the relay joint forming the reinforcing structure is fixed to the intermediate attachment member joined to the intermediate portion of the middle ceiling beam sandwiched between the above-mentioned ceiling beams. The intermediate mounting member is provided with a temporary placing portion which is capable of temporarily placing the free end portion of the intermediary connecting portion at a stage before being fixed to the intermediate mounting member.

[Operation] The building unit of the present invention forms a part of the building in a joined state in which the upper ends of the pillars constituting the building unit of the other party joined thereto are arranged corresponding to the middle portion of the mid-ceiling beam by itself. Will be done.

At this time, in the building unit of the present invention, a T-shaped reinforcing structure is coupled to the middle ceiling beam and the ceiling beams on both sides thereof via the middle attaching member and the main attaching member, respectively. . Therefore, from the upper end of the pillar of the building unit of the other party, the horizontal load extending to the middle portion of the middle ceiling beam in the building unit of the present invention, through the relay joint portion of the reinforcing structure coupled to the middle ceiling beam, It flows from the main joint to the ceiling beams on both sides, and is distributed to other parts of the building. That is, it is possible to reliably reinforce the middle ceiling beam having relatively low strength and rigidity by the reinforcing structure to prevent the localized concentrated load thereof and the deformation thereof.

In addition, when connecting the reinforcing structure to the middle ceiling beam and the ceiling beams on both sides, the main joint is performed with the free end of the relay joint part temporarily placed on the temporary placement part provided on the middle attachment member. The part can be fixed to the corresponding main attachment member of both side ceiling beams. Therefore, for example, it is not necessary for three workers to support both ends of the main joint and the free end of the relay joint,
Construction workability can be improved, for example, construction can be performed by only two workers who support both ends of the main joint portion.
