2. Description of the Related Art Conventionally, construction work such as electrical equipment, sanitary equipment, and air conditioning equipment in the ceiling has been concentrated as work after the completion of construction work of the building, and there is a process conflict in these works. To do. The sprinkler piping for sanitary equipment is carried out prior to the ceiling finishing work and has a large construction volume. Further, the construction of the refrigerant pipe for the indoor unit of the heat pump air conditioner, which is the air conditioning equipment, is carried out at the same time as the construction of the sanitary equipment. Furthermore, the construction of lighting equipment for electrical equipment, power supply lines for indoor units of heat pump air conditioners, smoke detectors, and light electrical wiring for speakers overlap with sanitary equipment construction and air conditioning equipment construction, and a process negotiation is necessary. .

As described above, in the construction of an office building, it is necessary to carry out various on-site work for electrical, sanitary, and air-conditioning facility work in the ceiling between the completion of the construction work and the start of the ceiling finishing work. In addition, since these works overlap each other, there is a problem in that there is a need for process cooperation.

SUMMARY OF THE INVENTION An object of the present invention is to use an office PC floor and a PC floor which can reduce the on-site work of each facility construction such as electricity, sanitation and air conditioning as much as possible and can rationalize the work. It is to provide the floor of the office building. Further, another object of the present invention is to solve the process conflict of each facility work such as electricity, sanitation and air conditioning, and shorten the process from the completion of the construction work of the building to the start of the ceiling finishing work. To obtain a PC floor and an office building floor using the PC floor.

[0005]

In order to solve the above problems, in the office PC floor according to the present invention, the floor of the office building is modularized, and each module is embedded with an electric cable, sprinkler piping, and refrigerant piping by a PC board. It is characterized by being configured. In order to solve the above-mentioned problems, an office building floor according to the present invention is a standard specification office PC floor having the above-mentioned configuration, and a pillar notch is provided at one or two positions in the standard specification office PC floor. Around the office PC floor, a machine room with a refrigerant pipe branching to the above standard specification office PC floor or a crossover refrigerant pipe to another PC floor. A sprinkler instead of the refrigerant piping on the above standard specification office PC floor. It is characterized in that the perimeter office PC floor provided with piping and the office PC floor having a different span from the standard specification office PC floor are allocated and joined.

[0006]

According to the office PC floor of the present invention, the office building floor is modularized at the construction planning stage, and the line of each facility for electricity, sanitation and air conditioning is determined, and electric cables, sprinkler piping, and refrigerant piping are prepared in advance. It is possible to complete the main electrical, sanitary, and air-conditioning equipment construction by making a PC board that has been driven in at the factory, bringing it into the field, installing it, and joining the PC floors together.
Until the start of the ceiling finishing work, it is sufficient to perform some remaining site work for facility work in the ceiling, which can eliminate the concentration of facility work in the ceiling and the conflict with other works.

According to the floor of the office building of the present invention,
Floor P by modularizing the office building floor at the construction planning stage
C board layout drawing is made, and the standard specification office PC floor manufactured around the factory as a PC board with electric cables for electric, sanitation and air conditioning equipment, sprinkler piping, and refrigerant piping pre-stamped, office PC floors around pillars, The floors of the office building on the standard floor that are equipped with the main electrical, sanitary, and air conditioning equipment by allocating and joining the office PC floor around the machine room, the office PC floor in the perimeter section, and the office PC floors with different spans according to the above diagram. By doing so, it is possible to significantly shorten the process of each electrical, sanitary, and air conditioning facility work from the completion of the building structure work to the start of the ceiling finishing work.
