2. Description of the Related Art In recent years, long-lasting durability of a concrete structure building has been achieved. However, even though concrete structures can be used for a long period of time, existing buildings must be renovated in accordance with deterioration of interior parts and changes in family composition due to long-term residence. There is a need for a high degree of freedom like a skeleton house that can remodel its interior. Since the renovation of the interior involves the relocation of electrical equipment such as lighting equipment and communication equipment, and the change of the water surrounding equipment, a structure such as a double floor or a double ceiling that is easy to renovate is desired.

[0003]

However, when a double floor or double ceiling is adopted, the height of the ceiling is greatly reduced. In particular, double ceilings differ from double floors, which are used relatively effectively due to storage under the floor and installation of water supply and drainage pipes. Must be used, and wasteful space is generated and is not used effectively.

On the other hand, in the case where wallpaper or the like is pasted on a ceiling slab to secure a large living space and a ceiling is directly installed, if lighting equipment or communication equipment is relocated at the time of renovation, electricity and communication for the relocation will be required. Since the wiring had to be exposed in the living room and had to be wired, there was a problem that the appearance was spoiled.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and secures a ceiling height and allows for a high degree of freedom in transferring or adding lighting equipment or communication equipment without exposing electrical and communication wiring. It is an object of the present invention to provide a ceiling structure of a concrete structure capable of being constructed.

[0006]

In order to achieve the above object, a ceiling structure of a concrete building according to the present invention forms a wiring space through which indoor electric / communication wiring is inserted, and the above-mentioned electric / communication is provided on the outer peripheral portion thereof. A pipe material capable of forming a lead-out hole for wiring is buried so as to be flush with the lower surface of the straight ceiling.

That is, since the wiring space is provided by burying the pipe material in the straight ceiling, electric / communication wiring can be inserted into the pipe material and easily wired in the straight ceiling. In addition, since this pipe material is exposed on the lower surface of the straight ceiling, it is possible to provide a lead-out hole for electric / communication wiring at an arbitrary position of the pipe material, and the electric / communication wiring is provided outside the straight ceiling from the draw-out hole. Can be pulled out. Therefore, even in the case of a lighting fixture or the like provided on an existing straight ceiling, the electric wiring and the like are re-wired through the pipe material and drawn out from a drawing hole provided at a desired position of the pipe material, so that electric power is externally provided. The lighting equipment and the like can be easily moved without exposing the wiring and the like. Further, since the lower surface of the straight ceiling is formed flush, a wide space can be secured without reducing the ceiling height of the space below the straight ceiling.
