BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit-type building formed by combining a plurality of building units each having a rectangular parallelepiped skeleton in which upper and lower ends of four corner columns are interconnected by beams.

[0002]

2. Description of the Related Art Conventionally, unit-type buildings constructed by combining a plurality of box-shaped building units manufactured in a factory at a building site have been used. As shown in FIG. 8, the upper and lower ends of pillars 121 at the four corners are connected to ceiling beams 122 and 123 and floor beams 124 and 1 as a building unit 100 forming a unit-type building.
It generally has a rectangular framework 120 connected at 25. The frame 120 of the building unit 100 includes, in a factory, ceiling materials supported by ceiling beams, interior materials such as floor materials supported by floor beams and partition walls that partition the roof, and lightweight foam concrete plates ( An external wall material or the like made of, for example, an “ALC plate” is attached. According to such a unit-type building, the work of assembling the interior material and the outer wall material to the building unit 100 is performed in the factory, and thereafter, the fixing work between the building units and the building unit on the first floor and the foundation is performed. Just because the building will be completed,
Work on the construction site is greatly reduced, and the merit that construction work can be completed in a short time can be obtained.

In such a unit-type building, the upper end surface of the pillar 121 and the upper edge surface of the ceiling beams 122 and 123 are flush with each other, and the lower end surface of the pillar 121 and the lower edge of the beams 124 and 125 are provided. Of the building unit 100 so that the
Since 0 is formed, when the two building units 100 are stacked up and down, only a small gap is formed between the ceiling beam 122 and the floor beam 124 and between the ceiling beam 123 and the floor beam 125. For this reason, in order to insert a horizontally extending member extending in the horizontal direction such as an electric wire or a sewage pipe provided on the ceiling wall, beams 122 to 125, for example, as shown in FIG.
An insertion hole TH is provided in the floor beam 125, as shown in FIG. 9, and a horizontally extending member such as the sewage pipe 130 and the electric wire 131 is inserted through the insertion hole TH as shown in FIG.

[0004]

However, the beam 122
By opening the insertion hole TH to ~ 125, if there are many horizontal extending members installed across multiple building units,
If a large number of insertion holes TH are provided in a concentrated manner in accordance with the number of these horizontally extending members, the strength of the beams 122 to 125 is reduced, so that
It is necessary to disperse these through holes TH. For this reason, there is a problem that the degree of freedom of installation of the horizontal extension member is reduced, the total extension distance of the horizontal extension member is increased, and the amount of work for installing the horizontal extension member is increased. Further, even if the insertion holes TH are dispersed, a plurality of the insertion holes TH must be provided, which causes a problem that the efficiency of the work of processing the beams 122 to 125 is reduced. In order to solve the above problem, the present applicant has filed Japanese Patent Application No. 10-34446.
