Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) This invention relates to a ceiling panel duct system that provides an air conditioning duct function to the ceiling panel.

(Prior Art) Conventional piping work for air conditioning ducts has been carried out through the following steps.

■Make the ducts in advance based on the design documents.

■Fix each duct to the bottom of the slab via hanging bolts.

■Set the air outlet and connect each duct.

■Insulate the outer periphery of the duct.

■After completing the above steps, paste the ceiling material at the bottom of the duct,
Connect the air outlet and duct.

(Problems to be solved by the invention) However, in the above steps ①, ②, and ②, places such as complicated bends are not necessarily as per the design documents, and require on-site work processes such as so-called actual preparation. In the past, manual duct fabrication and connection work were required, which required a large amount of man-hours.

In addition, in this type of air conditioning duct, if the duct is passed under the beam, the ceiling height will be smaller, requiring a descending wall, and even if the duct's piping valve is at the same floor height, the ceiling height will be smaller. The height was lower, which had the disadvantage that the floor height had to be set larger.

Furthermore, with this duct method, when repairing or maintaining the air conditioning duct once installed in the ceiling, the ceiling material must be removed one by one, or inspection openings are made at strategic points in advance, and inspection holes can be opened at key points from where the air conditioning duct is installed in the ceiling. I had to go into the back and carry out repairs, inspections, etc.

This invention was made in view of the above conventional drawbacks,
The purpose is: ■To complete the construction in an extremely short period of time without having to construct the ducts on-site, and to be able to finish the ceiling at the same time.

■It is possible to increase the ceiling height when the ceiling is finished, or to keep the floor height correspondingly low.

■It should be possible to perform piping according to the design documents, or to easily change the layout after construction, and to be able to easily perform repairs and inspections.

It is in.

(Means for Solving the Problems) In order to achieve the above object, the present invention basically arranges ceiling panels with air flow passages formed therethrough under the slab, and connects each ceiling panel in the lateral direction. This is characterized in that the respective flow passages are communicated with each other to form a predetermined air conditioning duct route, and that the duct route is made to circulate within the military through an opening formed on the lower surface of an arbitrary ceiling panel.

(Function) By joining the air flow passages of the units that make up the ceiling panel laterally in accordance with the design, the air conditioning duct piping will be completed at the same time as the ceiling surface is completed.

(Example) Hereinafter, an example of the present invention will be described in detail using the drawings.

Fig. 1 is a plan view showing the ceiling surface of a room to which the ceiling panel duct system of the present invention is applied, and Fig. 2 is a plan view of the ceiling panel of Fig. 1.
FIG.

In the figure, the ceiling surface of the room is formed by connecting ceiling panels consisting of each unit described below, which are formed to the same size and the same thickness, in a NWA pattern avoiding the ceiling light 1, and connecting them to the lower surface of the slab 2 via hanging bolts 3. It is suspended and fixed.

FIGS. 3(a) to 3(q) show front sectional views of each of the units.

First of all, (a) in the same figure shows a spacer unit 4. This spacer unit 4 is a solid unit with no airflow passage formed, and has only the function of a ceiling material placed in a non-piping position of a duct. It is something that

FIG. 2B shows a straight tube unit 5, and this U tube unit 5 has a straight tube-shaped air flow passage 5a formed toward the opposing sides.

FIG. 1C shows the elbow unit 6, and inside the elbow unit 6, there are formed air flow passages 6a in the form of curved tubes that open at each of the connecting sides.

Figure (d) shows a variable damper unit 7. This unit 7 has a linear airflow passage 7a similar to the straight pipe unit, and inside thereof expands and contracts in a diamond shape. A variable damper 7b is incorporated. Although not shown, the variable damper 7b is driven in the opening or closing direction by a motor or the like provided on the back side of the ceiling of the unit 7.

FIG. 2E shows an air outlet unit 8, in which an air intake port 8a is formed on one side of the air outlet unit 8, and an air outlet 8b is formed on the lower surface of the air intake port 8a. Although not shown, the opening surface of the air outlet 8b is covered with a grid, punched metal, or the like.

FIG. 2(f) shows a filter unit 9, and an air flow passage 9a is formed in this filter unit 9, which is open at both ends and widened inside. Set 9b. Note that it is desirable that the filter unit 9 be able to be removed from the lower surface of the ceiling so that only the filter 9b can be replaced in a cassette style.

In the same figure (l is a booster fan unit 10, inside this unit 10 is formed an air flow passage 10a that opens only on the suction side and expands into a circular shape inside, and inside this air flow passage 10a). A fan 10b is arranged.The fan 10b is rotatably driven by a fan drive motor (not shown) arranged on the back side of the ceiling of the unit 10.

And each unit 5 to 10 except spacer unit 4
are the units constituting the ceiling panel duct system of the present invention, and the air flow passages 5a, 5a, 7a,
9a, 10a and the air intake port 8a are each provided with a male and female joint portion 11.12, and by connecting each unit 5 to 10 via this joint portion 11.12, the joint portion is airtight. , can be bonded to a strong bonded state.

Note that the joint portions 11 and 12 may adopt an airtight joint structure such as a one-touch joint for a gas pipe, for example.

Next, a more detailed configuration of the straight pipe unit 5 will be explained using FIG. 4 and FIGS. 5(a) and 5(b).

The straight pipe unit 5 in FIGS. 4 and 5(a) has a Karasuhei elliptical cylindrical duct 5-2 arranged inside a hollow body 5-1 of a predetermined thickness made of a lightweight material such as aluminum, The aforementioned male and female joint portions 11 and 12 are provided at both end openings, and the inside of this duct 5-2 serves as the aforementioned air passage.

The hollow interiors of the duct 5-2 and the hook body 5-1 are filled with a heat insulating material 5-3 such as urethane foam to thermally isolate the duct 5-2 from its periphery.

Further, a ceiling finishing material 14 is fixed to the lower surface of the i-body 5-1. This ceiling finishing material 14 may be pasted after the ceiling surface is constructed by each unit.

Furthermore, it goes without saying that each unit other than the straight pipe unit 5 has a structure similar to this structure, so a description thereof will be omitted.

Next, if you want the ceiling finishing material to be a radiant surface, see Figure 5 (
As shown in b), the hook body 5-1 and the duct 5-2 are kept in a hollow state, and the heat insulating material 5-4 is pasted on the E side of the eight bodies 5-1, and the bottom surface of the hook body 5-1 is By attaching a metal plate 15 that also serves as a ceiling finishing material with good heat conductivity to the duct 5-2, the duct 5-2 and the metal plate 15 are bonded in a heat conductive state, and the conditioned air passing through the duct 5-2 is A part of the heat can be used for radiant cooling through the metal plate 15.

Of course, this example can also be applied not only to the straight pipe unit 5 but also to other units.

Note that the thinner each unit is, the greater the ceiling height, which is advantageous, but the aspect ratio of the duct increases accordingly, which is disadvantageous in terms of flow resistance. Therefore, if the inside of the duct is laterally partitioned with a plurality of shielding plates, the disadvantages of having a thin unit can be overcome.

Therefore, when the units 4 to 10 are arranged as shown in FIG. 1, their respective airflow passages communicate with each other to form a predetermined duct path, which communicates with the room via the outlet unit 8. The supply end side of this duct route may be concentrated in one place and communicated with the main duct M.

(Effects of the Invention) As explained in detail in the above embodiments, according to the present invention, ■Since the duct route is formed at the same time as the ceiling panel unit is assembled, on-site construction is required compared to the conventional duct piping work. There is no need for piping, which shortens the construction period, and there is no need to consider connections with beams, etc., so piping can be installed according to the design.

■The ceiling material is thicker than before, but since there is no duct placed above it, the ceiling height can be increased, and if the ceiling height is the same, the floor height can be set lower.

■Each unit can be easily removed during maintenance inspections or when changing the layout, so there is no need to work behind the ceiling compared to conventional models, and rearrangement is also easier.
