Generally, a building unit, which is a constituent unit of a unit building, occupies a position in the unit building, for example, a building unit on the top floor and a building unit used on the first floor of a two-story building. , One of a three story building
In a building unit or the like used for a floor, since the load applied to the building unit is different, the mechanical strength required for structural members such as beams such as ceiling beams and floor beams and columns is different.

The strength required for structural members such as beams and columns also differs depending on the size of the building unit. However, since the building units are mass-produced in a factory, it is extremely inconvenient to use different beams and columns for the building units according to the purpose. In order to solve such inconvenience, it is conceivable to determine the structural material according to the building unit that requires the most mechanical strength. However, there is a problem that the building unit that does not require mechanical strength becomes excessive quality and becomes expensive. is there.

In addition, when a structural material is determined in accordance with the building unit having the smallest mechanical strength, and the strength is required to be greater than the structural material, the beams and columns are reinforced by the means described in Conventional Examples 1-3. However, this has the following problem. That is, in a unit building, in the case of pillars, pillars erected at four corners are connected by floor beams or ceiling beams, and in the case of beams, floor pillars formed in a predetermined shape in advance are used. Beams and ceiling margins are attached to floor beams and ceiling beams, and building units are installed adjacent to each other.

Therefore, when the beam of the building unit is reinforced by the means described in the prior art example 1, the outer dimensions of the beam are changed, so that it becomes difficult to attach the floor beam and the ceiling ridge, and the building unit can be installed adjacent to the beam. become unable. If the column is reinforced by the means described in Conventional Example 2, there is no problem when attaching a floor beam or a ceiling beam, but there is a problem that it is difficult to attach a + -shaped reinforcing member in a square cross section.

Further, when the column is reinforced by the means described in the conventional example 3, the strength in the direction along the reinforced surface increases, but the strength in the direction substantially perpendicular to the direction hardly increases. Therefore, an object of the present invention is to provide a unit building reinforced with a structure suitable for a building unit.

Since the reinforcing plate of the character-shaped cylindrical body is attached, both the beam and the column can be changed according to the requirement of mechanical strength, which is convenient. In addition, since the beams and the columns are assembled in a ramen structure, the building unit is a rigidly connected beam and columns.

According to the fourth aspect of the present invention, at least one building unit includes a ceiling unit and a long ceiling beam having a U-shaped cross section, and the ceiling unit includes a long ceiling beam having a U-shaped cross section. Since the web of the ceiling beam and the web of the ceiling beam of the ceiling unit are connected, the thickness of each ceiling beam can be saved, and the unit building can be made inexpensive. In addition, since the web of the ceiling beam of the long U-shaped cross section of the building unit is connected to the web of the ceiling beam of the long U-shaped cross section of the ceiling unit, the ceiling ridge is bridged over the ceiling beam, The ceiling edge can be attached as before, which is convenient.

According to the fifth aspect of the present invention, the reinforcing plate is sandwiched between the web of the ceiling beam of the building unit and the web of the ceiling beam of the ceiling unit. Therefore, the thickness of the ceiling beam and the roof beam can be saved correspondingly, and the unit building can be inexpensive.

In the invention according to claim 6, a reinforcing frame composed of columns and beams assembled in substantially the same shape as the outer wall is attached to the outer wall composed of columns and beams of at least one building unit. Therefore, the mechanical strength of the building unit increases as much as the reinforcing frame is attached. Moreover, since this reinforcing frame has almost the same shape as the vertical surface of the building unit that is exposed to the outside, when adding this reinforcing frame, once remove it and install a new building unit,
It can be conveniently used by attaching it to the outside of a new building unit.
