[Problems to be Solved by the Invention] By the way, when the conventional floor structure described above is adopted, a dead space is formed between the concrete slab and the ceiling surface that is not used effectively. There is a problem in that it is not possible to secure space for use by people. Therefore, a so-called reverse beam is installed that protrudes from the top surface of the concrete slab that divides a building into upper and lower floors, and by supporting the flooring material on this reverse beam, an underfloor space can be formed between the concrete slab and the flooring material. It is conceivable to adopt this structure.

[0004] If a reverse beam structure is adopted in an apartment building in this way, a large volume of space under the floor can be secured, which can be used to store electrical equipment such as air conditioners and central cleaners. Become.

[0005] The present invention makes more effective use of the underfloor space by rationally processing the piping and wiring connected to the electrical equipment when electrical equipment is installed in the underfloor space of a building such as an apartment complex. The purpose is to achieve this goal.

[0006]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides reverse beams projecting from the upper surface of a horizontal frame that partitions a building into upper and lower floors, and a large drawer constructed between the reverse beams. In a building in which an underfloor space is formed between the floor surface and the horizontal frame by supporting flooring on the upper surface, electrical equipment for air conditioning or cleaning is installed in the underfloor space and connected to this electrical equipment.
