Description

The present invention relates to a radiant air conditioner for a building in which the lower surface of the ceiling is made of a bent steel plate having an uneven cross section such as a deck plate, and a radiant panel used for the radiant air conditioner.

In a steel-framed building, a deck plate with an uneven cross section is used as the structural material for the ceiling slab, concrete is placed on the upper surface of the deck plate, a control panel is laid on the upper surface of the deck plate, or the deck. Flooring is used to cover the upper surface of the plate.

Then, it has been proposed to use the deck plate as an air conditioner. As an example, in Patent Document 1, in a building in which concrete is placed on the upper surface of the deck plate, the fluid of the air conditioner flows on the upper surface of the deck plate. It is disclosed that the pipes are arranged and the deck plate is also used as the radiation panel of the radiation air conditioner. Therefore, in Patent Document 1, the pipe through which the fluid flows is embedded in the concrete layer.

On the other hand, it has also been proposed to use the valley portion of the deck plate as a passage for air-conditioned air. For example, in Patent Document 2, the ceiling plate is fixed to the lower surface of the deck plate via a heat insulating material, so that the deck plate can be used. The valley is used as a passage for conditioned air, and conditioned air is discharged into the room for blow-out type air conditioning, or radiated air conditioning is performed using heat exchange between the conditioned air and the ceiling plate. Is disclosed.

Japanese Patent No. 6143089 Japanese Patent No. 3444691

Compared to the air conditioner that blows out air conditioning air, the radiant air conditioner that exchanges heat between the radiant panel and the fluid has many advantages such as excellent quietness because no wind is generated. The configuration of Patent Document 1 has the advantage that the structure is simplified because the deck plate is also used as the radiation panel, but the heat of the pipe is dissipated to the concrete, and the deck plate is a steel plate, which does not necessarily have heat transfer efficiency. However, it is understood that the energy efficiency of the air conditioner is not always good.

Also, since the pipe through which the fluid flows is buried inside the concrete, there is a problem that it cannot be replaced even if corrosion occurs, a problem that it cannot be removed even if it is no longer needed, or the concrete and deck plate at the pipe location. Since the adhesion to the slab is reduced, there is a concern that the function as a synthetic slab may be reduced.

On the other hand, in Patent Document 2, since the ceiling material attached to the deck plate is used as a radiation panel, the problem of Patent Document 1 does not occur, but the valley portion of the deck plate must be sealed with the ceiling material, so that the construction can be performed. There are problems such as troublesomeness.

The present invention has been made to improve such a situation.

The invention of the present application includes various configurations, and a typical example thereof is specified in each claim. Of these, the invention of claim 1 is
"A radiant air conditioner installed in a building where the lower surface of the ceiling is composed of bent steel plates with a concave cross section in which downward peaks and upward valleys are alternately formed.
It includes a support attached to the bent steel plate, a radiant panel horizontally supported by the support, and a pipe provided on the radiant panel through which an air conditioning fluid flows . "
In the basic configuration
"The radial panel is formed in a shape that is long in the longitudinal direction of the valleys and peaks of the bent steel sheet, and is set to a width dimension that closes one or more valleys of the bent steel sheet from below.
Upright pieces abutting the lower surface of the mountain portion of the bent steel plate are formed on both longitudinal edges of the radiation panel, and a large number of ventilation holes are intermittently formed in the upright pieces along the longitudinal direction. "
It has the feature.

The invention of claim 2 embodies claim 1, and in this invention,
"The support is stretched and engaged with a horizontal elongated groove formed on the inner surface of the valley portion of the bent steel plate, and the radiation panel is suspended and supported by a suspension rod provided on the support. ing"
It is configured as.

The invention of claim 3 has the same basic configuration as that of claim 1.
"The radiating panel is formed in a long shape in the longitudinal direction of the valleys and peaks of the bent steel sheet, and is arranged in a state of being inserted into the valleys of the bent steel sheet."
It has the feature.

The invention of claim 4 has the same basic configuration as that of claim 1.
"The radiation panel, the bend is formed longitudinally elongated valleys and ridges in the steel sheet, the large number the radiation panels, series arranged, et al are in a state spaced apart in the longitudinal direction Radiation
During the radiation panel adjacent to the arrangement direction of the series, it is arranged a cover having the same appearance as the radiation panel as viewed from the bottom side, pipe provided on the radiation panel, wherein adjacent is, on the cover It is connected by a joint member in the space of
It has the feature.

In the present invention, since radiant air conditioning is performed by a radiant panel provided with a pipe through which a fluid flows, a material having excellent heat transfer properties can be used as the radiant panel, and heat dissipation loss between the fluid and the radiant panel can be used. Can be suppressed and heat exchange can be performed efficiently. Therefore, the air conditioning efficiency is excellent and it can contribute to energy saving.

Further, although various supports for deck plates are commercially available, in the present invention , commercially available supports can be used, so that the work is easy and the cost can be suppressed. .. Further, unlike Patent Document 2, it is not necessary to seal the valley portion of the bent steel sheet, so that the work is easier. Furthermore, since it is a method of retrofitting after the construction of the building and it is easy to replace or remove it , it is excellent in maintainability and also highly flexible when remodeling the room. It is also excellent in terms that can be applied to existing buildings.

There is a deck plate as a representative of bent steel plate, but there are various forms of deck plate, and an engaging part (reinforcing part) such as a ridge or a long groove is provided on the inner surface of the valley part to support this engaging part. Some of them are designed so that the tools can be stretched and locked. The invention of claim 2 utilizes this form of the deck plate and the support, and the radiation panel can be easily suspended without any special processing on the deck plate. Therefore, it is excellent in practicality. Further, since the support tool penetrates into the valley portion of the bent steel plate, the radiation panel can be arranged as high as possible. Therefore, the radiant air conditioner can be finished with a good appearance.

Various forms and arrangements can be adopted for the radial panel, but if a form that is long in the longitudinal direction of the valleys and peaks of the bent steel sheet is adopted as in claim 1 and arranged so as to close the valleys of the bent steel sheet, It is possible to prevent or suppress the exposure of the unevenness of the bent steel plate and improve the aesthetic appearance of the ceiling portion. Further, since the valley portion of the bent steel plate functions as a heat insulating air layer, the heat of the fluid can be suppressed from being transferred to the bent steel plate, so that it can be said that the air conditioning efficiency is also excellent.

In claim 1 , if one radiating panel is set to a width dimension that closes one valley of the bent steel plate, for example, the radiating panel is arranged so as to close every other valley of the bent steel plate. It can be arranged in detail. Therefore, it is excellent in flexibility. On the other hand, if the radiant panel is set to a width dimension that closes a plurality of valleys, the radiant area of one radiant panel can be increased, so that heat leakage can be suppressed and the air conditioning efficiency can be improved.

If the radiation panel is arranged so as to close the valley portion of the bent steel plate as in claim 1 , convection may occur in the valley portion of the bent steel plate due to the heat of the radiation panel. If the configuration of item 1 is adopted, the convection generated in the valley can be released to the room through the ventilation hole of the standing piece, and conversely, the air in the room can be taken into the valley through the ventilation hole, so that the fluid and the room can be taken in. It is possible to promote heat exchange with and to improve air conditioning efficiency.

When the radiating panel is inserted into the valley of the bent steel plate as in claim 3 , it is possible to prevent the radiating panel from being conspicuous when a person looks up at the ceiling. Therefore, it is useful when the height of the ceiling surface is low.

Since there is a limit to the length of the radiator panel, a radiation air-conditioning apparatus, will connect a large number of radiating panels pipe arrangement to each radiating panels in series joint member, in the configuration of claim 4 Since the pipes can be connected to each other in a space covered with a cover having the same appearance as the radiant panel, fluid can flow through the pipe of each radiant panel while unifying the design of the ceiling. Therefore, it is excellent in reality.

Next, an embodiment of the present invention will be described with reference to the drawings. In each embodiment, a deck plate is used as a bent steel plate, and concrete is cast on the deck plate. In the following, the words "front-back / left-right" are used to specify the direction, but the front-back direction is the longitudinal direction of the valleys and peaks on the deck plate, and the left-right direction is the longitudinal direction of the valleys and peaks on the deck plate. It is a width direction (arrangement direction) orthogonal to the longitudinal direction.

(1). Basic structure of the first embodiment In FIG. 1, the building to which the present invention is applied is roughly displayed. The floor slab (ceiling slab) of a building is constructed by placing concrete 2 on the upper surface of a deck plate 1 formed by bending a steel plate into an uneven shape. In FIG. 1, the wall is also displayed as a concrete layer, but the wall is often composed of an ALC plate or the like.

As is clearly shown in FIG. 3, the deck plate 1 has an uneven shape in which an upward valley portion 3 and a downward mountain portion 4 are continuous in the left-right direction, and the cross-sectional shape of the valley portion 3 and the mountain portion 4 is trapezoidal. It has become. An upper elongated groove 5 and a lower elongated groove 6 are formed on the left and right inner side surfaces of the valley portion 3 over the entire length. Further, a downward ridge 7 is formed at an intermediate position between the left and right sides of the upper surface of the valley portion 3.

The radiant air conditioner includes a group of supports (hanging supports, hangers) 8 attached to the valley portion 3 of the deck plate 1 and a group of radiating panels 9 suspended and supported in a horizontal posture by the supports 8 . .. The support 8 includes left and right arms 10 that are flexibly connected in a front view, and a vertical suspension bolt (double-cut bolt) 12 that is screwed into the connecting portion 11 of the left and right arms 10. A pair of cam bodies 13 that are spread out by the hanging bolts 12 are provided on the upper part of the cam body 13. The hanging bolt 12 is an example of the hanging rod described in the claim.

When the upper end of the hanging bolt 12 is located below the cam body 13, the left and right arms 10 can be arranged at a position higher than the lower elongated groove 6 of the deck plate 1 with a small angle. Then, when the hanging bolt 12 is screwed in from below with a tool such as a full-screw wrench, the upper end of the hanging bolt 12 hits the upper surface (downward ridge 7) of the deck plate 1, but when the hanging bolt 12 is further screwed in, by the right and left cam body 13 is widened distance between the right and left cam member 13 is pushed, spread included angle formed by the left and right arms 10 of both the front end of the lateral arm 10 Ru Tsuppa below elongated groove 6, hanger rod 12 The upper end of the deck plate 1 is stretched over the upper surface of the deck plate 1 and is held so as not to fall.

Therefore, the support 8 is stretched to the valley portion 3 of the deck plate 1 in a state of being supported at three points, and is fixed to the deck plate 1 so as not to be detached. As the rotating means of the hanging bolt 12, instead of using a full-screw wrench, a wrench engaging means such as a grind or a square hole is formed on the lower end surface of the hanging bolt 12, and a minus type or hexagonal wrench is formed. It is also possible to rotate with.

(2). Radiation panel The radiation panel 9 is a substrate 14 having a width dimension that is slightly longer than the opening width of the valley portion 3 of the deck plate 1 and is elongated in the longitudinal direction of the valley portion 3 and the mountain portion 4 of the deck plate 1. And a pair of left and right pipes 16 mounted on the substrate 14 via separate heat sinks 15. A fluid flows through the pipe 16 as an air conditioning medium , and hot water or cold water is generally used as the fluid.

The substrate 14 is made of a metal plate such as a steel plate or an aluminum plate, and has a width dimension of, for example, about 200 mm. Without even described dare, substrate 14, heat transfer is as high as possible materials are preferred. The length of the substrate 14 can be set arbitrarily, but for example, it can be a long type of about 2000 mm or a short type of about 1000 mm. In the embodiment, the long type is displayed.

An upward standing piece 17 is bent and formed on the left and right longitudinal side edges of the substrate 14, and a U-shaped folded-back portion 17a opened downward is formed at the upper end of the standing piece 17. The rigidity of the substrate 14 is remarkably increased due to the presence of the upright piece 17, but the rigidity is further increased because the U-shaped folded portion 17a is formed at the upper end.

As is clearly shown in FIG. 2C, a large number of groups of front-rear longitudinal ventilation holes 18 are intermittently formed in the upright piece 17 at appropriate intervals in the front-rear direction. The ventilation holes 18 are formed in two stages, and the distance between the ventilation holes 18 adjacent to each other in the longitudinal direction is set to the same size as the length of the ventilation holes 18. The ventilation holes 18 may be formed in only one stage or in three or more stages, and the front-rear length and pitch thereof can be arbitrarily set. A large number of round holes may be formed. When forming in a plurality of stages, the length and the arrangement position may be different for each stage (a staggered arrangement is also possible).

The heat sink 15 is, for example, an extruded product of aluminum, and has a flap that overlaps the substrate 14 and a holding portion 15a to which the pipe 16 is forcibly fitted against elasticity. If the heat sink 15 is made of the same material as the substrate 14, it can be fixed by welding such as spot welding. For different materials, bonded or Once good double-sided adhesive tape or adhesively bonded (cases of the same type material, Ru can be integrated by bonding.).

Although both ends of the heat sink 15 are located inside the both ends of the substrate 14, the heat sink 15 and the substrate 14 may be aligned to the same length. When the heat sink 15 is made shorter than the substrate 14, the dimensional difference can be arbitrarily set. It is also possible to integrally form the holding portion by using the substrate 14 as an extruded product of aluminum (in this case, the heat sink 15 as a separate member is unnecessary).

The substrate 14 is suspended and supported by suspension bolts 12 of the support 8 at a plurality of locations separated from each other in the longitudinal direction. That is, the hanging bolts 12 are fitted into the mounting holes 19 made in the substrate 14 from above, and are fixed by the upper and lower nuts 20 and 21. If the radiation panel 9 of the length of the short type of about 1000 mm, if may only radiation panel 9 is Tsu支both ends thereof in support 8, the length of the long type of about 2000mm, as shown in FIG. 2 As shown in (A), mounting holes 19 may be provided at three locations, the front and rear ends and the front and rear intermediate portions, and the three locations may be suspended.

In the present embodiment, the front and rear ends of the pipe 16 are exposed to the outside from the front and rear ends of the standing piece 17. The pipes 16 of the radiation panels 9 adjacent to each other in the longitudinal direction are connected by the joint member 22 simply shown in FIG. 2 (A). Therefore, although there is a space between the radiation panels 9 adjacent to each other in the longitudinal direction, this space is closed by the cover 23 having the same shape as the substrate 14. The cover 23 also has an upright piece 17 having the same shape as the radiation panel 9, and although it is not specified, the upright piece 17 of the cover 23 also has a ventilation hole 18 similar to that of the radiation panel 9. Further, the cover 23 is also suspended and supported by two front and rear supports 8.

(3). Summary Installation of the radiation panel 9 is performed by, for example, the following procedure. That is, after temporarily holding the support 8 corresponding to each radiation panel 9 and the cover 23 in the lower elongated groove 6 of the deck plate 1, first, the support 8 is positioned so that the radiation panel 9 is in a predetermined position. Then, each radiation panel 9 is set at a predetermined position, and the substrate 14 of the radiation panel 9 is fixed to the suspension bolt 12 with the upper and lower nuts 20 and 21.

In this case, since the operator's hand enters above the radiation panel 9 at both ends of the radiation panel 9, the upper nut 20 is held at a predetermined height, and then the upper nut 20 is made non-rotatable. By screwing the lower nut 21 into the hanging bolt 12 in the held state, the substrate 14 can be sandwiched and fixed between the upper and lower nuts 20 and 21.

On the other hand, when the length of the radiation panel 9 is long and the hanging bolt 12 penetrates in the middle part, the operator cannot reach the part of the hanging bolt 12 in the middle part, so that the hanging bolt 12 in the middle part cannot be reached. Two 20 and 21 nuts are screwed into the part exposed below the radiation panel 9, and the two nuts 20 and 21 are in close contact with each other to form a non-rotatably locked double nut. The radiation panel 9 may be supported by a double nut.

After fixing each radiating panel 9, the pipes 16 of the adjacent radiating panels 9 are connected by a joint member, then the support 8 for the cover 23 is accurately positioned and the cover 23 is nuts 20, 21. Support with. When attaching the cover 23, the operator's hand cannot be inserted above the cover 23, so the two nuts 20 and 21 are screwed into the hanging bolts 12 below the cover 23 so that they are in close contact with each other. It is a held double nut.

In the case of the long type radiating panel 9, since the upper nut 20 cannot be reached in the front and rear middle portions, as described above, the two nuts 20 and 21 are arranged under the radiating panel 9 and rotated. It may be a double nut that is locked impossible, but instead, two upper nuts 20 are placed on the radiation panel 9 as double nuts so that they cannot rotate, and from under the radiation panel 9. It is also possible to screw one nut 21 into the hanging bolt 12 to fix it.

There are two rows of pipes 16 in one row of radiating panels 9, but in the group of radiating panels 9 arranged in a row located at one end, the two pipes 16 are shown in FIG. 2 (A). As shown by the alternate long and short dash line, they make a U-turn and are connected together. Therefore, in the group of the radiation panels 9 in one row, the group of pipes 16 is connected to one as a whole, and water flows in from one end thereof, makes a U-turn at the end of the row, and flows out from the other end. However, it is also possible to flow water individually through the two pipes 16.

As described above, the radiation panel 9 is suspended and supported by the support 8 attached to the deck plate 1 by using the long groove 6, but since the support 8 can use a commercially available product, the work is easy and the cost is high. Can also contribute to the suppression of.

Air convection (convection flowing in the vertical direction) may occur inside the valley portion 3 due to a temperature difference between the substrate 14 and the deck plate 1 (or a temperature difference between the upper and lower sides of the substrate 14). When a large number of ventilation holes 18 are formed in the standing piece 17 as described above, convection generated inside the valley 3 flows out from the ventilation holes 18 as shown by an arrow in FIG. 3 (B), or conversely. By allowing the air in the room to enter the inside of the valley portion 3, it is possible to prevent or suppress the trapping of air inside the valley portion 3 and improve the air conditioning efficiency.

Further, in the present embodiment, since the radiation panel 9 is in a state of protruding downward by the height of the standing piece 17 from the mountain portion 4 of the deck plate 1, the ceiling surface is opposite to the unevenness of the deck plate 1. Unevenness appears as a line. Therefore, it can be said that the aesthetic appearance of the ceiling surface can be improved as compared with the case where the entire lower surface of the deck plate 1 is exposed.

Hot water or cold water is supplied to the pipe 16 of the radiation panel 9 located at the end of the row from a water supply device (not shown). The radiating panels 9 are arranged at each valley 3 of the deck plate 1, but the pipes 16 of the adjacent rows of the radiating panels 9 may be connected in a zigzag shape, or a plurality of rows may be connected as one block. , Water supply and drainage may be performed for each block.

Further, it is not necessary to arrange the radiation panels 9 in all the valleys 3 of the deck plate 1, and the radiation area is set according to the required air conditioning capacity, for example, by arranging the radiation panels 9 every other row. I should do it. It can be said that it is preferable to arrange a cover having the same appearance as that of the radiation panel 9 in the valley portion 3 where the radiation panel 9 is not arranged so that the design of the ceiling surface can be unified.

The lighting device can be arranged in the valley 3 where the radiant air conditioner is not arranged. In this case, if the translucent cover of the lighting device is formed to have an appearance provided with the upright piece 17 similar to the substrate 14, the design in the ceiling portion is made. (In this case, the upright piece of the translucent cover may or may not have a hole similar to the ventilation hole 18).

(4). 2nd to 4th Embodiments and 1st to 2nd Reference Examples Next, other embodiments shown in FIG. 4 and the following will be described. In the second embodiment shown in FIG. 4, one radiation panel 9 is set to cover the two valleys 3. That is, it is a double type in which two radiation panels 9 of the first embodiment are connected to the left and right. Also in this embodiment, two pairs of heat sinks 15 and pipes 16 are provided on the left and right sides so as to be located below the valley portion 3. The radiation panel 9 of the embodiment is a long type, and mounting holes 19 are also formed in the front and rear intermediate portions.

In the present embodiment, four pipes 16 are arranged on one radiating panel 9, but when the pipes 16 of the group of radiating panels 9 are configured as one as a whole, first, the group of radiating panels 9 is arranged. Of the ones located at one end of the row, as shown by the alternate long and short dash line in FIG. 4 (A), the two outer pipes 16 are connected in a U-turn shape, and then the row of the radiation panel 9 group. The pipe located at the other end may be connected in a U-turn shape of the two inner pipes 16 as shown by the alternate long and short dash line in FIG. 4 (A). Therefore, the inflow and outflow of water is performed by the radiation panel 9 located at the other end of the row. It is possible to flow water independently through the four pipes 16, or it is possible to flow water by setting two pipes 16 as a set.

In the third embodiment shown in FIG. 5, the lighting device 25 is arranged at a portion between the adjacent radiation panels 9. The lighting device 25 includes a main body case 26 suspended by a support 8 and a translucent cover 27 attached to the main body case 26 from below, and the main body case 26 has a straight tubular shape via a holder 26a. The lamp 28 is attached. A downward piece 29 is provided on both left and right ends of the main body case 26, and an engaging claw portion 30 projecting outward is formed on the downward piece 29.

On the other hand, the translucent cover 27 has the same shape as the substrate 14 of the radiation panel 9, and the folded-back portion 31a formed on the standing piece 31 is locked to the engaging claw portion 30 of the main body case 26 from above. The standing piece 31 may or may not have a hole in the same state as the ventilation hole 18 of the radiation panel 9.

In this embodiment, the ends of the pipe 16 do not protrude from the substrate 14, and both ends are bent upward. A hose-shaped joint member 22 is arranged so as to straddle the lighting device 25. Although the power cable can be laid on the substrate 14 of the radiation panel 9, the wiring duct 32 may be attached to the hanging bolt 12 of the support 8 as shown by the alternate long and short dash line in (A).

In the first reference example and the second reference example shown in FIG. 6, the substrate 14 of the radiation panel 9 is used as a part of the lighting device. That is, in the first reference example shown in (A), the LED lamps 34 are arranged on the lower surface of the mountain portion 4 of the deck plate 1 via the circuit board 33, while they are located on the left and right sides of the LED lamps 34. The substrate 14 of the radiation panel 9 is tilted toward the LED lamp 34. Therefore, the left and right substrates 14 serve as reflectors for the lighting device.

In the second reference example shown in FIG. 6B, the substrate 14 of the radiation panel 9 is formed in a V shape, while the sideways H-shaped lamp support 35 is provided on the lower surface of the mountain portion 4 in the deck plate 1. A group of LED lamps 34 are arranged so as to irradiate light in the lateral direction on the vertical portion of the lamp support 35 fixedly. In this embodiment, the light of the LED lamp 34 is reflected only on the substrate 14 of the radiation panel 9 and irradiates the room, so that the lighting is completely indirect. The LED lamp 34 may be arranged on the lower horizontal flange or the upper horizontal flange of the lamp support 35.

The fourth embodiment shown in FIG. 7 is also an example of the lighting device. In this embodiment, the LED type lighting device 25 is arranged on the mountain portion 4 of the deck plate 1 in the first embodiment. The lighting device 25 has a downward-opening U-shaped main body case 37 in which an LED lamp 34 is arranged on the lower surface, and a translucent cover 38 that closes the main body case 37 from below. A claw 39 that engages with a ventilation hole 18 provided in the upright piece 17 of the substrate 14 is projected outward from 37a.

Further, while the inward flange 40 is formed at the lower end of the downward side plate 37a of the main body case 37, the claw body 41 that engages with the inward flange 40 is provided on the longitudinal side edge of the translucent cover 38.

(5). 5th-7th Embodiment / 3rd Reference Example FIG. 8 shows an embodiment in which the radiation panel 9 is inserted into the valley portion 3 of the deck plate 1. Of these, in the fifth embodiment shown in FIG. 8 (A), the support 8 is substantially the same as the first embodiment, but the radiating panel 9 is provided by locating the connecting portion 11 as high as possible in the valley portion 3. It is invading Tanibe 3. Standing pieces 17 are formed on the left and right edges of the substrate 14.

In the sixth embodiment shown in FIG. 8B, the substrate 14 is formed on a flat plate, and the support 8 overlaps the lower surface of the substrate 14. The support 8 is composed of two arms 42 that are flexibly connected to each other. The backing plate 43 is applied to the connecting portion of the arm 42 from below, and the connecting portion of the arm 42 is connected to the substrate by the bolt 44 and the nut 45. By sandwiching the 14 and the backing plate 43, the left and right arms 42 are held in the shape of a single plate and stretched into the lower elongated groove 6 of the valley portion 3. The nut 45 is fixed to the upper surface of the substrate 14 by welding or the like (may be formed by burring).

In FIG. 9, it is applied to the deck plate 1 in which the inverted trapezoidal dovetail groove 46 is formed on the lower surface of the mountain portion 4. That is, first, in the third reference example shown in FIG. 9A, an expandable support (suspension support) 47 whose upper end is widened by screwing in the suspension bolt 12 is attached to the dovetail groove 46 and attached to the suspension bolt 12. The substrate 14 is fixed with nuts 49. Further, in this reference example , the substrate 14 is formed by extruding aluminum, and the holder portion 14a is integrally formed with the substrate 14. It is also possible to configure a multi-unit system in which a plurality of valleys 3 are closed by one substrate 14.

Next, in the seventh embodiment shown in FIG. 9B, the radiation panel 9 has entered the inside of the valley portion 3, and the left and right plate-shaped supports 50 and 51 overlap the lower surface of the substrate 14. One ends 50a and 51a of the supports 50 and 51 are fastened to the substrate 14 together with bolts 52. At the other end of the supports 50 and 51, a hook portion 53 that is hooked and engaged with the dovetail groove 46 from the side is formed, and when the end portions 50a and 51a are fastened together with the substrate 14, the supports 50 and 51 are It is held on the deck plate 1 inseparably.

Although the embodiments of the present invention have been described above, the present invention can be embodied in various ways. For example, the support is not limited to the suspension method using a long groove or a dovetail groove, but a method of fixing to the deck plate with a fastener such as a screw or a method of welding to the deck plate can also be adopted. Further, depending on the deck plate, there is a type in which a large number of inward ribs are formed, but it is also possible to attach a support using the ribs.
