Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a floor structure equipped with an air conditioner.

(Prior art) and (problems to be solved by the invention) With the progress of office automation, the number of double-layered floors has inevitably increased.

Therefore, there was a drawback that the ceiling height was correspondingly lower and the office space became narrower.

Furthermore, when occupants try to selectively adjust the air conditioning according to their own preferences, the unique fit of the system becomes a problem.

(Means for Solving the Problems) The present invention was proposed to solve these problems, and the present invention was proposed in order to solve the above-mentioned problems. An air conditioning facility is provided in the space formed between the floor plate and the groove in a double floor formed by placing a floor plate between the protrusions, and lighting is provided in the space below the protrusion. The present invention relates to a floor structure equipped with an air conditioner characterized by the arrangement of appliances.

(Function) As described above, in this invention, by using a PC floor slab in which protrusions and concave grooves are arranged alternately, pockets are created on the floor and on the ceiling, respectively. Utilizing the space formed between the concave groove and the floor plate disposed between the protrusions, an air conditioning facility is built into the space, and conditioned air is guided from the air conditioning facility onto the floor. On the other hand, by utilizing the ceiling space formed on the lower surface of the ridge in the PC floor slab, lighting equipment is arranged in the same space.

(Effects of the invention) As described above, the present invention has a floor structure consisting of a PC floor slab in which concave grooves and ridges are arranged alternately, and a floor plate arranged between each of the ridges. By configuring this structure, a sufficient ceiling height can be secured, and the underfloor space formed between the groove and the floorboard and the ceiling space formed on the lower surface of the protrusion can be used for air conditioning facilities and lighting, respectively. By using the space as a storage space for equipment, it is possible to avoid hindrance to the storage of OA equipment, and because the PC floor slab has a shape in which concave grooves and protrusions are arranged alternately, It has greater shear strength than ordinary floors and requires fewer beams.

(Example) The present invention will be described below with reference to the illustrated embodiments.

A is a PC floor slab in which concave grooves 1 and protruding grooves 2 each having a trapezoidal cross section are arranged alternately.

Then, a plurality of the PC floor slabs A are connected, and a floor plate 3 is fitted onto the upper part of the concave groove 1 between the adjacent protrusions 2, and the floor plate 3 and the PC floor slab A are connected together. A
The floor is made up of:

A lighting fixture 4 is arranged in the ceiling space B formed on the lower surface of the protrusion 2, while the space formed between the groove 1 and the floor plate 3 has an inner circumferential surface insulated. A supply duct C covered with a material 5 and connected to an air conditioner (not shown) is formed, and a cold/hot air supply pipe 6 branched out from the duct C is connected to a desk D arranged on the floor. , the user of desk D can freely extract hot and cold air according to his or her preference.

In the figure, numerals 7 and 8 are outlet ports of the supply pipe 6.

In addition, in the space formed between the concave groove 1 and the floorboard 3 of the PC version A, a cold and hot water supply pipe 9, a cold and hot water return pipe 10, and a cold and hot water outlet 11 connected to both the pipes 9 and 10 are installed. Built-in, same outlet 11
is connected to the fan coil unit 12 installed on the desk D, and the user of the desk D can freely take out cold and hot air via the fan coil unit 12 according to his/her preference. .

In the figure, 13, 14, and 15 are the fan, coil, and outlet of the fan coil unit 12, respectively.

The cold and hot air supplied from the cold and hot air supply pipe 6 and the fan coil unit 12 of the desk D is passed through the suction port 16 provided in the floorboard 3 between the concave groove 1 of the PC board A and the floorboard 3. It is returned through the rethane chamber E formed in .

According to the illustrated embodiment, as described above, a PC floor slab A in which concave grooves 1 and protruding grooves 2 are alternately arranged;
An underfloor space and a ceiling space are formed on the upper surface of the groove 1 and the lower surface of the ridge 2 by the floor plate 3 fitted between the adjacent ridges 2 at the upper part of the groove 1, In addition, a floor structure with a sufficient ceiling height is constructed, and the space formed between the groove 1 and the floor plate 3 is used as a housing space for the cold/hot air supply duct C and the air conditioning facility. By using the space under the ridge 2 as a space for arranging the lighting equipment 4, it is possible to arrange the air conditioner lighting equipment without hindering the installation of OA equipment, and it is also possible to arrange the lighting equipment for the air conditioner without hindering the installation of office equipment. It is possible to extract hot or cold air according to your preference.

In addition, since the PC floor slab A is a floor slab with a continuous trapezoidal groove shape, it has a higher shear strength than a normal floor and requires fewer beams. This is a frame that spans the groove 1, so there is little misalignment.
