Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a duct panel suitable for use in an air conditioning system for air conditioning a building.

[0002]

2. Description of the Related Art In recent years, in order to improve comfort in buildings,
Various air conditioning systems are used. One of them is a centralized air conditioning system that can perform centralized air conditioning including air conditioning, heating and ventilation.

This central air-conditioning system provides conditioned air to each room through a branch-like air supply duct that is arranged in the floor panel or the ceiling panel of the building and leads to each room of the building. The supply of air supplies air conditioning.

The air supply duct is generally installed in the second-floor panel or the first-floor ceiling panel so as to cross the building longitudinally or transversely, and the main duct branches from the side of this main duct to each room. It is configured to have a plurality of sub-ducts that extend so as to communicate with each other. A tip portion of the sub-duct which communicates with each chamber is opened toward each chamber and serves as an air outlet.

According to the air supply duct thus constructed, it is arranged in the second floor panel or the first floor ceiling panel at the factory in advance, so that the second floor panel or the first floor can be installed at the time of on-site construction. While installing the ceiling panel,
The duct connection construction can also be performed. For this reason, it is preferably used because it can simplify the on-site construction and save labor.

Of the air supply ducts, the main duct is formed by connecting duct panels D to each other as shown in FIG. The duct panel D includes a frame body 52 assembled into a rectangular outline by two vertical core members 51a and horizontal core members 51b arranged at intervals, and surfaces attached to both sides of the frame body 52. Air passage 54 defined by the members 53a and 53b and the frame 52 and the face members 53a and 53b.
(54a, 54a) is made up of a reinforcing core member 55 arranged in parallel with the vertical core member 51a inside the frame body so as to be vertically divided into two. It should be noted that the horizontal core member 51b is provided with an opening 56 which serves as an outflow / inflow port for air.

[0007]

By the way, in recent years, the size of the panel is increasing (longer) for the purpose of simplifying the construction, and the above-mentioned duct panel has a special device to meet the demand for the size increase. Is required.

That is, when the duct panel becomes large,
Since it is spanned between large spans, the bending rigidity of the duct panel itself must be increased, and in order to meet this, it is considered to increase the height of the core material such as the horizontal core material 51b or the vertical core material 51a. To be

However, if the height of the core material is increased, the sectional area of the air passage formed inside the duct panel is inevitably increased. Even if the cross-sectional area of the air passage of the duct panel becomes large in this way, the air passages of other members connected to this duct panel remain the same cross-sectional shape as before, and therefore, the duct panel and A sudden expansion or a sudden contraction occurs at the connection with other air passage components. Then, due to the sudden expansion or the rapid contraction, the air flow resistance of the duct system becomes large, and as a result, a predetermined amount of air cannot be obtained in each room, which causes a problem that desired cooling and heating cannot be performed.

The present invention has been made in view of the above circumstances, and provides a duct panel capable of coping with an increase in size (lengthening) by increasing bending rigidity without changing the cross-sectional shape of an internal air passage. The purpose is to do.

[0011]

According to a first aspect of the present invention, there is provided a frame body assembled into a rectangular contour by a vertical core member and a horizontal core member, which are spaced apart from each other, and attached to both surfaces of the frame member. In a duct panel having an air passage therein, the width dimension of one of the face materials is defined by the above-mentioned face material and a heat insulating material disposed inside the face material and the frame. It is set to be smaller than the inner dimension of the pair of vertical core members forming the frame body, the one face member is inserted between the vertical core members, and the heat insulating material is arranged inside the same. Further, a fixing means for fixing one face member to the vertical core member is provided.

According to the second aspect of the present invention, a frame body assembled into a rectangular contour by a vertical core member and a horizontal core member arranged at intervals, and a face member attached to both surfaces of the frame member. When,
In a duct panel having an air passage therein, which is composed of the face material and a heat insulating material arranged inside the frame body, a reinforcing member is vertically provided on the outer surface of at least one of the both face materials. It is characterized in that it is attached so as to correspond to the core material.

Further, in the invention according to claim 3, a frame body assembled into a rectangular contour by a vertical core material and a horizontal core material arranged at intervals, and a face material adhered to both surfaces of the frame body. And a heat insulating material disposed inside the face material and the frame body, in a duct panel having an air passage inside, between the inner surface of at least one of the both surface materials and the heat insulating material. It is characterized in that a spacer is interposed therebetween.

[0014]

According to the first aspect of the present invention, since the face material is inserted between both the horizontal core materials, even if the height of the horizontal core material or the vertical core material is increased, the distance between the both side materials is increased. It can be kept constant, and therefore, if the interval between the core members is set to the same level as in the conventional case, the bending rigidity of the panel duct itself can be increased without changing the cross-sectional shape of the air passage.

According to the second aspect of the present invention, a reinforcing member is provided on the outer surface of at least one of the double-sided materials of the duct panel having substantially the same cross-sectional structure as the conventional one, at a position corresponding to the vertical core material. Since it is a structure attached to the same as in claim 1, if the interval between the core members is set to the same level as the conventional one, the bending rigidity of the panel duct itself is increased without changing the cross-sectional shape of the air passage. be able to.

Further, according to the invention of claim 3, since the spacer is interposed between the heat insulating material and the inner surface of at least one of the double-sided materials, the air passage surrounded by the heat insulating material. The cross-sectional area of the panel duct can be kept constant irrespective of the variation of the distance between the double-sided materials, and as a result, the cross-sectional shape of the air passage inside the panel duct can be changed without changing it. The bending rigidity of itself can be improved.

The duct panels 15 are connected to each other so as to respectively communicate the two internal air passages 18a, 18a partitioned by the reinforcing core member 16c.

A duct panel 15 forming the main duct 5 and a duct panel 24 forming the sub duct 8 are provided.
The joining structure of is also joined by a similar method. here,
Like the duct panel 15, the duct panel 24 forming the sub-duct 8 is mainly composed of a frame body assembled in a rectangular contour and face materials attached to both surfaces of the frame body. However, the reinforcing core material is not arranged inside,
It differs from the main duct 5 in that only one air passage is secured. In addition, the duct panel 24 is provided with a hole that communicates with each chamber and opens in the face material near the end opposite to the side where the duct panel 15 that forms the main duct 5 is joined.

Here, in the duct panel 15 of this embodiment, since the height of the vertical core member 16a is made higher than that of the conventional duct panel, the bending rigidity becomes large, and therefore,
Even if it is hung between beams with a large span (not shown), no trouble will occur.

Further, the face member 17 is made up of both vertical core members 16a, 16c.
Since it is configured to be inserted between the upper and lower face members 17, despite having a large bending rigidity as described above,
The spacing between the 17 can be as small as a conventional duct panel. Therefore, the cross-sectional shape of the air passage 18 formed inside the panel duct does not change, and when connecting to the air passage of another portion different from the panel duct, there is no portion such as a sudden contraction or a sudden expansion. The resistance of the air passage can be kept at the same level as the conventional one.

Second Embodiment FIGS. 4 and 5 show a second embodiment of the present invention. The feature of this embodiment is that a square bar 30 is provided on the outer surface of either one of the double-sided materials 17, 17 of the duct panel having substantially the same cross-sectional structure as the conventional one. In this embodiment, the same components as those in the first embodiment are designated by the same reference numerals.

That is, as shown in the figure, the vertical core member 1 is the lower surface of the face member 17 attached to the lower surface of the frame body 16.
The timber 30 is fixed to the positions corresponding to 6a and 16c. The fixing method of the square members 30 is as follows:
And a method of applying an adhesive between them and nailing so as to reach the vertical core members 16a and 16c from the outside of the square member 30,
Alternatively, a method of fixing with through bolts so as to reach the square bar from the vertical core member 16a can be considered. Even with such means, the bending rigidity of the duct panel itself can be increased without changing the cross-sectional area of the air passage inside the panel duct, as in the first aspect.

In addition, with such a structure, the conventionally used members (vertical core material, face material, etc.) can be shared by increasing the length without changing the height, In addition to facilitating the management of parts, the square material 30
It can be obtained by extremely simple work such as fixing
There is also an advantage that production is easy.

FIG. 6 shows a third embodiment of the present invention. The feature of this embodiment is that the double-sided materials 17 and 1 constituting the duct panel are used.
The spacer 40 is interposed between the heat insulating material 19 and the inner surface of at least one of the surface materials 17 (lower surface material) of the seven. By thus interposing the spacer 40, the space between the upper and lower face members 17 can be made substantially the same as that of the conventional duct panel, although the vertical core members 16a and 16c having a high height are used. . Here, the spacer 40 is made of a heat insulating material having substantially the same shape as the heat insulating material 19 forming the air passage 18, that is, a heat insulating material having a U-shaped cross section, but the material of the spacer 40 is not limited to this. The shape and shape can be variously changed, and may be made of lightweight metal such as aluminum or wood.

Even with such means, the bending rigidity of the duct panel itself can be increased without changing the cross-sectional shape of the air passage inside the panel duct, as in the first and second embodiments.

The duct panel of the present invention is not limited to the above-mentioned embodiment, and the specific structural requirements such as the shape of the duct panel, the structure of the building and the air conditioning system, etc. can be appropriately changed in the implementation.

For example, in the above embodiment, the main duct 5
Although the present invention is applied to the duct panel 15 that forms the above, the present invention is not limited to this and may be applied to the duct panel 24 that forms the sub-duct 8.

[0043]

According to the first aspect of the present invention, since the face material is inserted between both vertical core members, even if the height of the horizontal core member or the vertical core member is set high, The space between the materials can be maintained at a value similar to that of the conventional duct panel, and thus the bending rigidity of the duct panel itself can be increased without changing the cross-sectional shape of the air passage inside the panel duct. As a result, the form of the connecting portion with other members forming the air passage (for example, the outlet part of the air conditioner) is made the same as the conventional form in which the change in the cross-sectional shape is small without sudden reduction or enlargement. As a result, it is possible to secure an air passage with low flow resistance, and to have sufficient strength as a duct panel for a large span that is passed between beams that are widely spaced apart from the conventional one. .

According to the second aspect of the present invention, the reinforcing member is provided on the outer surface of at least one of the double-sided materials of the duct panel having substantially the same cross-sectional structure as the conventional one, at a position corresponding to the vertical core material. Since the structure is attached to the panel, the bending rigidity of the panel duct itself can be increased without changing the cross-sectional shape of the air passage inside the panel duct.

Further, according to the invention of claim 3, since the spacer is interposed between the heat insulating material and the inner surface of at least one of the double-sided materials, the air passage surrounded by the heat insulating material is formed. The cross-sectional area can be kept constant irrespective of variations in the distance between the double-sided materials, and as a result, as in claim 1 or claim 2, the cross-sectional shape of the air passage inside the panel duct itself does not change. The bending rigidity of can be improved.
