Description

  The present invention relates to a ceiling having an air conditioning function and a sound absorption function.

  There is a radiant air conditioning system (radial air conditioning system) that uses a liquid (fluid) such as water as a heat medium and cools or heats with a liquid panel that is cooled or heated by the liquid, and this air conditioning system has noise It is widely used because it has the advantage of superior comfort and the like.

  The radiation panel is formed in a square in a plan view, and is laid vertically and horizontally aligned in a plan view. In addition, since the lower surface of the radiation panel has a flat aspect and an aspect (for example, Patent Document 1), if the lower surface is uneven as in Patent Document 1, the heat transfer area becomes large, so the air conditioning efficiency is improved. There is an advantage that can be improved.

  On the other hand, in order to improve the indoor environment, it is widely practiced to configure the ceiling surface of the building with a sound absorbing ceiling material, and as an example thereof, in Patent Document 2, grooves having different depths are alternately formed. A sound absorbing panel is disclosed. Although the ceiling board which formed the lower surface in the waveform is disclosed by patent document 3, it is estimated that this ceiling board also has a sound absorption function.

JP, 2008-275227, A Design Registration No. 1545418 Unexamined-Japanese-Patent No. 2002-235434

  By the way, when providing the air conditioning equipment which consists of a radiation panel in the ceiling part of a building, arranging a radiation panel almost in the whole ceiling part is seldom carried out, generally, the range which is several percent among the ceiling parts is made into an air conditioning area. There is. If the lower surface of the radiation panel is formed as an uneven surface as in Patent Document 1, the air conditioning efficiency becomes high, so that the arrangement area can be narrowed, and the cost can be suppressed accordingly.

  As described above, when the air conditioning area does not extend over the entire ceiling, the area which is not the air conditioning area will be constituted by the normal ceiling material, and generally the periphery of the air conditioning area is surrounded by the area which is the ordinary ceiling material There are many methods. Alternatively, when the area of the room is large, a plurality of air conditioning areas may be provided, and the margin portion may be configured with a normal ceiling material.

  A common ceiling material is generally a compacted or sintered product of an inorganic material such as gypsum board, and the lower surface is flat. Therefore, if the air-conditioning area is configured by the radiation panel having the lower surface formed uneven as in Patent Document 1, the forms of the lower surface of the air-conditioned area and the other areas are significantly different, and some people feel uncomfortable. It is concerned that there is a case.

  The present invention has been made to improve such a current situation, and by combining quietness, which is one of the features of a radiant air conditioning system, with sound absorption of the ceiling, the indoor environment is improved while the ceiling is improved. The purpose is to improve the appearance by unifying the design of the entire department.

The present invention includes various configurations, typical examples of which are specified in the respective claims. Among them, the invention according to claim 1 is characterized in that the air-conditioned area constituted by the group of radiation panels in a square in plan view is in contact with the sound absorbing area similarly constituted by a group of sound absorbing ceiling materials in a square in plan view;
The lower surface of the radiation panel and the lower surface of the sound absorbing ceiling material are uneven surfaces in which downward protrusions and downward groove lines are alternately arranged, and the unevenness of the radiation panel and the unevenness of the sound absorbing ceiling material are the same. The shape and size are set, and the radiation panel and the sound absorbing ceiling material are arranged so that the unevenness of the both extend in the same direction.

The invention of claim 2 is characterized in that
The radiation panel in the air conditioning area and the sound absorbing ceiling material in the sound absorption area are arranged such that their downward protruding ridges and downward downward grooves are in a straight line, and the longitudinal direction of the downward protruding ridge and downward downward grooves The radiation panel and the sound absorbing ceiling material adjacent to each other have an appearance suspended by a hanging tool having a flange on which the ends of the radiation panel and the sound absorbing ceiling material rest, and the flange of the hanging tool is An uneven shape fitted from below to the unevenness of the radiation panel and the sound absorbing ceiling material is formed.

The invention of claim 3 is characterized in that, in claim 1 or 2,
The radiation panel is provided with a radiation plate which is curved in a convex-concave shape, the downward ridge is an upward groove, the downward groove is an upward ridge, and the upward groove The pipe through which the air conditioning fluid passes is attached directly or through a heat sink.

The invention of claim 4 is any one of claims 1 to 3 wherein
The downward protrusion is a trapezoid with a downward taper, and the downward groove is a downward flare.
The left and right end portions of the radiation panel and the sound absorbing area are formed of downward protrusions when viewed from the longitudinal direction of the downward protrusion and the downward groove, and the outward edges are directed to the upper edges of the downward protrusions of the left and right ends. The rim is formed over the entire length,
The plurality of radiating panels and the sound absorbing ceiling material have the same pitch of the downward protrusion and the downward groove by setting the width of the edge piece to half of the distance between the upper ends of the adjacent downward protrusions. It is possible to arrange it in a lined state.

  Although various materials can be adopted for the sound absorbing ceiling material, according to the invention of claim 5, a molded article of rock wool is adopted as the sound absorbing ceiling material.

  In the present invention, since the ceiling of the building (room) is composed of the air-conditioned area composed of the radiation panel and the sound absorbing area composed of the sound absorbing ceiling material, it is possible to create an excellent indoor environment in terms of sound.

  That is, since the air conditioning system consisting of the radiation panel is much quieter (almost silent) than the air conditioning system of the blowout system, the noise from the air conditioning equipment does not make people feel uncomfortable, and the sound absorption area By the presence of the sound, it is possible to suppress the diffuse reflection of the sound generated in the room, so that it is possible to suppress the roughness and to make a comfortable sound environment / atmosphere easy to listen to human voice and music.

  And since the lower surface of the radiation panel and the sound absorbing ceiling material have the same shape, when a person enters the room from the entrance, the entire ceiling part enters the eye, and the ceiling is looked up while sitting on a chair. However, because the air-conditioning area and the sound-absorbing area are unified in design, they do not feel uncomfortable and are excellent in aesthetics.

  Therefore, in the present invention, it is possible to provide an indoor structure excellent in aesthetic appearance, sound environment and air conditioning efficiency.

  The radiation panel has to have a flange and a vertical part and needs to be suspended by a hanging tool called a T-bar, while the sound absorbing ceiling material is a screw or the like for the frame material or the upper ceiling material It is often fixed by Therefore, although the attachment structure of the sound absorbing ceiling material and the radiation panel is often different originally, in the place where the radiation panel and the sound absorbing ceiling material are adjacent, the joint structure of both is given It is desirable to enhance aesthetics by doing so.

  In this respect, when the configuration of claim 2 is adopted, since the flanges of the concavo-convex shape are fitted from below to the lower surfaces of the adjacent sound absorbing ceiling material and the radiation panel, the panels of the same form are continuous Give a good appearance and can significantly improve the aesthetics.

  According to the second aspect of the present invention, in extending the configuration of the second aspect of the present invention, in hanging the end portions of the radiation panel adjacent in the longitudinal direction of the downward protrusion and the downward groove with a hanger, It is preferable to form in the shape which fits in. Thus, not only can the downward ridges and the downward grooves of the adjacent radiation panels and the sound absorbing ceiling material form a straight continuous appearance, but the downward ridges and downward grooves of the adjacent radiation panels Since a straight and continuous appearance can also be formed, the appearance of a state where the unevenness of the ceiling portion extends in a straight line can be formed, and an excellent appearance with a unified design can be created.

  In addition, about a sound absorbing ceiling material which adjoined the longitudinal direction of the downward protrusion and the downward groove, arrange a slight gap and arrange it, and arrange a concavo-convex flange in the place of the gap between both. In this case, since the sound absorbing ceiling material and the radiation panel can not be distinguished, the uniformity in design can be further enhanced. It is more preferable to unify the colors of the lower surface of the radiation panel and the lower surface of the sound absorbing ceiling material by coating the same color or pattern.

  The radiation panel can adopt various cross-sectional shapes, and for example, it is possible to form only the lower surface in a concavo-convex shape and adopt a flat structure on the upper surface, as in claim 3 Adopting an equal thickness structure has the advantage of being able to ensure high heat transfer efficiency while being lightweight. The pipes may be disposed in all of the plurality of upward grooves, or the pipes may be disposed in the upward grooves in a jumping state, such as one jump or two jumps.

  The concave and convex shapes on the lower surface of the sound absorbing ceiling material and the radiation panel can be set arbitrarily, but adopting a shape in which the inverted trapezoidal and the trapezoidal are alternately arranged as in claim 4 makes it possible to improve the design with a sharp appearance.

  Although various materials can be adopted for the sound absorbing ceiling material, it is preferable to adopt a molded article of rock wool (rock wool sound absorbing material) as in claim 5, since high sound absorbing performance can be secured.

It is the perspective view which looked at the ceiling part which concerns on embodiment from the downward direction. It is an exploded perspective view. It is a partial top view. (A) is an AA cross-sectional view of FIG. 3, (B) is a BB cross-sectional view of FIG. 3, (C) is a CC cross-sectional view of FIG. (A) is the isolation front view of the location of an illumination part (for convenience, the sound-absorbing ceiling material is also displayed), (B) is a partial perspective view.

(1). Overview Next, an embodiment of the present invention will be described based on the drawings. In FIG. 1, the entire ceiling of the room is displayed. In this embodiment, an air conditioning area 2 is formed below the ceiling slab by a group of radiation panels 1 in a rectangular shape in plan view (bottom view), and the air conditioning area 2 is a sound absorbing ceiling material 3 in a rectangular shape in plan view. It is enclosed by the sound absorption area 4 which consists of groups. The sound absorbing area 4 is indicated by a large number of dots for the sake of clarity.

  In this embodiment, the terms front and rear and left and right are used to specify the direction, but as clearly shown in FIGS. 1 and 2, the longitudinal direction of the radiation panel 1 and the sound absorbing ceiling material 3 in the front and rear direction It is defined as the width direction (short side direction) of the panel 1 and the sound absorbing ceiling material 3. The front view is a state seen from the front and rear direction, and the side view is a state seen from the left and right direction.

  Two lighting units 5 are provided in the air conditioning area 2. The lighting unit 5 is configured by providing a certain distance between groups of adjacent radiation panels 1 and is formed over the entire length in the front-rear direction of the air conditioning area 2. The illumination unit 5 can also be formed in the form of left and right longitudinal.

  The ends of the radiation panels 1 adjacent to each other in the front and rear direction are suspended by the left and right long hangers (T-bars) 6. Moreover, the hanger 6 is arrange | positioned also in the location of the radiation panel 1 and the sound-absorbing ceiling material 3 which adjoined back and front. Although the radiation panel 1 is suspended by the hanger 6 at the front and rear end portions of the air conditioning area 2, the sound absorbing ceiling material 3 has an appearance as if supported by the hanger 6, but the hanger 6 Not supported by

(2). Radiation Panel As shown in FIGS. 2 and 3, the radiation panel 1 includes a radiation plate 7 having a concavo-convex shape in cross section and a pipe 8 disposed in the upward groove thereof. That is, the radiation plate 7 has a substantially uniform thickness as a whole, and has a configuration in which a plurality of downward ridges 9 and upward grooves 10, downward grooves 11 and upward ridges 12 are alternately arranged at a constant pitch in the left-right direction. In each upward groove 10, a pipe 8 constituting a fluid passage is disposed. Since the radiation plate 7 has an equal thickness, the downward protrusion 9 and the upward groove 10 appear as an integral configuration of the front and back, and the downward groove 11 and the upward protrusion 12 appear as an integral configuration of the front and back.

  As shown in FIG. 2, the pipe 8 is bent in a zigzag shape in plan view, and each straight portion is disposed in each upward groove 10. As shown in FIG. 4 (B), the pipe 8 is attached to the radiation plate 7 via the heat sink 13 which spreads over the bottom of the upward groove 10. The ends of the pipes 8 of the radiation panels 1 adjacent to each other in front and rear are connected via a joint pipe (not shown). In addition, although the pipe 8 is attached to the heat sink 13 by forced fitting, you may join by brazing etc., and may adhere | attach with an adhesive agent or a double-sided adhesive tape.

  The heat sink 13 is bonded to the radiation plate 7 with an adhesive or a double-sided adhesive tape. When the extrusion plate is adopted for the radiation plate 7, the heat sink 13 is not necessary. Although it is not necessary to intentionally describe, in the pipe 8, an air conditioning liquid such as hot water or cold water is flowed by a water supply device (not shown).

  As shown in FIG. 3, a hollow reinforcing frame 14, which is long in the left-right direction, is overlapped and fixed to one or more places on the upper surface of the radiation plate 7. The reinforcing frame 14 is for preventing the deformation of the radiation plate 7, but it is also possible to suspend the reinforcing frame 14 with a suspension bolt.

  The downward protrusion 9 and the upward groove 10 have a trapezoidal shape that narrows downward (spreads upward), and the downward groove 11 and the upward ridge 12 have a trapezoidal shape that spreads downward (upper shrinkage). Therefore, the upper surface of the upward protrusion 12 is flat. Then, on both the left and right ends of the radiation plate 7, an edge piece 15 having a half width of the left and right width of the upper end of the upward protrusion 12 is formed over the entire length. Therefore, when the two radiation panels 1 are arranged in contact with each other in the left-right direction, as a whole, the unevenness is aligned at a constant pitch.

  When arranging the radiation panel 1 side by side to the left and right, the side end face of the edge piece 15 may simply be brought into contact, or one of the left and right edge pieces 15 may be formed with a step-down portion. It is also possible to form a step-up portion and to configure the step-down portion and step-up portion of the left and right radiation panels 1 to overlap vertically (in this case, the step-down portion and step-up portion are overlapped) In this condition, it is necessary to set the dimensions so that the unevenness is aligned at a constant pitch as a whole. In addition, the ratio of the right and left pitch of the unevenness | corrugation of the radiation | emission panel 1 and height (depth) can be set arbitrarily.

(3). Sound absorbing ceiling material, hanging tool, lighting part The sound absorbing ceiling material 3 is a molded product obtained by pressing and solidifying rock wool (rock wool), and the downward protrusion 16 and the downward groove 17 alternate in the left and right direction Lined up. The downward protrusion 16 and the downward groove 17 of the sound absorbing ceiling material 3 have the same size as the downward protrusion 9 and the downward groove 11 of the radiation panel 1 and accordingly, the unevenness and radiation of the lower surface of the sound absorbing ceiling material 3 The unevenness on the lower surface of the panel 1 has the same size and the same pitch.

  In addition, the upper surface of the sound absorbing ceiling material 3 is flat, and the left and right downward protrusions 16 are in a connected state via a band-like flat plate portion 18. Then, on both left and right ends of the sound absorbing ceiling material 3, edge pieces 19 having the same thickness as that of the flat plate portion 18 and a half width are protruded in a lateral direction. Therefore, when the sound absorbing ceiling materials 3 are arranged side by side, as a whole, the unevenness is aligned at a constant pitch, and the size and pitch of the unevenness are the same as the size and pitch of the unevenness of the radiation panel 1 .

  The sound absorbing ceiling material 3 can be fixed to a ceiling plate 20 made of gypsum board or the like with a screw 21 as shown in FIG. 4A, for example. It is also possible to fix to a ceiling frame, in which case it can be fixed, for example, with a drill screw. Alternatively, it is also possible to suspend with the hanger 6 without fixing with screws.

  When the sound absorbing ceiling material 3 is fixed with the screws 21, the sound absorbing ceiling materials 3 adjacent to each other in the front and back direction can be disposed in a state where the front and rear end surfaces thereof are in contact with each other. Accordingly, in the sound absorbing area 4, the boundary of the sound absorbing ceiling materials 3 lined up in front and back can not be clearly viewed clearly, and the rattan also has an appearance such as being constituted by one sound absorbing ceiling material 3.

  As shown in FIG. 3, the hanger 6 is composed of an uneven flange 22 and a vertical portion 23 provided on the upper surface thereof. The flange 22 is bent so as to closely overlap the lower surface of the radiation panel 1 and the lower surface of the sound absorbing ceiling material 3, and the vertical portion 23 is fixed at a longitudinal center of the flange 22. Therefore, the ends of the two radiation panels 1 adjacent to each other can be supported by one hanger 6. The vertical portion 23 is suspended by a suspension bolt (not shown).

  The radiation panel 1 and the sound absorbing ceiling material 3 which are adjacent to each other in front and rear have an appearance suspended by a single hanging tool 6, but as described above, the sound absorbing ceiling material 3 is the hanging tool 6. It is not suspended but merely engaged with the flange 22. Therefore, in the area of the air-conditioned area 2 and the sound absorbing area 4, the flange 22 of the hanger 6 plays only the role of a cover material or a joint material to the sound absorbing ceiling material 3 (the sound absorbing ceiling material 3 It may be suspended.).

  As shown in FIG. 5, the illumination unit 5 is formed in the space between the radiation panels 1 disposed apart from each other on the left and right, and is suspended on the edge 15 of the adjacent radiation plate 7. 24 and a cover 25 mounted on the main body case 24 from the lower side, and a lamp 26 such as a fluorescent lamp is attached to the main body case 24. The cover 25 is attachable to and detachable from the main body case 24. It is also possible to use an LED or an organic EL as a lamp. In FIG. 5, the pipe 8 and the heat sink 13 of the radiation panel 1 are omitted. Moreover, although the sound absorbing ceiling material 3 is displayed in FIG. 5 (A), this is for showing the front-back positional relationship of the unevenness | corrugation with the radiation panel 1 and the sound absorbing ceiling material 3. FIG.

  The interval W (the interval between the center positions) between the downward projecting ridges 9 adjacent to the left and right across the illumination unit 5 is set to an integral multiple of the pitch P of the unevenness in the radiation panel 1 and the sound absorbing ceiling material 3 There is. Accordingly, the asperities of the radiation panel 1 on both sides of the radiation panel 1 are aligned with the asperities of the sound absorbing ceiling material 3 disposed before and after the air conditioning area 2.

(4). Summary As described above, since the lower surface of the radiation panel 1 is uneven, the heat transfer area is much larger than in the case where the lower surface of the radiation panel 1 is flat. Air conditioning efficiency can be secured. Moreover, since the lower surface of the sound absorbing ceiling material 3 is also uneven, high sound absorbing performance can be ensured.

  And since the unevenness of the radiation panel 1 and the unevenness of the sound absorbing ceiling material 3 have the same size and pitch, the unevenness of the air conditioned area 2 and the unevenness of the sound absorbing area 4 can be made continuous in series. Because the whole looks like the same form (ie, because the design unity is made), it is excellent in aesthetics.

  In particular, as in the embodiment, the hanger 6 is disposed at a place where the radiation panel 1 and the sound absorbing ceiling material 3 are adjacent to each other, using the flange 22 having a concavo-convex shape as the hanger 6 Then, as shown in FIG. 5 (B), the downward protrusion 9 is extended without interruption over the entire front and rear length of the ceiling, so that the appearance can be further improved.

  In the embodiment, the projections and depressions of the radiation panel 1 and the sound absorbing ceiling member 3 are formed in a continuous trapezoidal shape, but various shapes such as forming in a corrugated shape or forming in a sawtooth shape as in Patent Document 3 An uneven shape can be adopted. The pitch of the unevenness can also be set arbitrarily.

  The present invention can be embodied in an air-conditioned ceiling. Therefore, it can be used industrially.
