The panels 2 and 5 comprise: an outer metal panel 6 exposed to the outside; a metal inner panel 8 exposed to an inside space 7; and a sound absorber 9 between the outer panel and the inner panel. The inner panel 8 has many small holes 8a. Some or all of the plurality of panels 2 and 5 have a pipe 11 through which water flows for air-conditioning. The pipe 11 is covered with the sound absorber 9 and in contact with the inner panel 8. Adapting a radiant air-conditioning system using water, the room can be silently air-conditioned. Therefore, the room provides a comfortable, silent space as well as achieves high sound insulation without air-conditioning noise.

Description

  The present invention relates to a sound insulation room having an air conditioning function. The sound insulation room referred to here is a room mainly installed in a building, and means a room having a function of absorbing sound generated inside while blocking the entry of sound from outside.

  The sound insulation room is simply designed to prevent (suppress) the entry / exit of sound (for example, Patent Document 1), and creates a silent state by absorbing the sound generated inside as well as entering / exiting the sound. Is mainly classified (for example, Patent Document 2). The latter silencing room is used, for example, for analysis of sound waves, inspection of acoustic equipment, or inspection of human hearing.

  In the case of a silent room that prevents the intrusion of sound from outside and absorbs sound generated inside, there are many cases where a person works in the room, and in this case, air conditioning is required. Conventionally, this type of air conditioner that blows out conditioned air is used, and an indoor unit having an air outlet and a suction port is arranged on the ceiling or wall of the room.

  On the other hand, it is widely practiced to improve sound insulation and soundproofing in general buildings. For example, in Patent Document 3, a sound absorbing material is incorporated into a radiant air conditioning panel, and a large number of small holes are formed in an inner surface plate exposed indoors. It is disclosed that sound absorption is improved.

JP 2000-17868 A JP 2008-2981 A JP 05-26479 A

  There may be various levels in the silent room, but if an air blowing type air conditioning unit is used, a sound will be generated when the conditioned air is blown out of the indoor unit, or a sound will be generated when the indoor air is sucked For this reason, there is a problem that it is difficult to raise the silence level.

  In this regard, a silencer that eliminates air blowing sound and inhaling sound is also incorporated in the indoor unit, but the indoor unit is only arranged in one place, so air conditioning unevenness is likely to occur. There was a problem.

  On the other hand, the air-conditioning method using a radiant panel as in Patent Document 3 has the advantage of being quiet and quiet because there is no flow of air. It consists of a radiant panel, has no idea of preventing the intrusion of sound from the outside, and could not be applied to a facility installed independently in a building.

  This invention is made in view of such a present condition, and it aims at providing the sound insulation room which can ensure a high silence state, ensuring air-conditioning performance.

  The present invention has various configurations, but typical examples are specified in each claim. Of these, the invention according to claim 1 is characterized in that at least a wall and a ceiling of a floor, a wall and a ceiling surrounding a sealed internal space are exposed to the outside and a porous metal layer exposed to the internal space. In a sound insulation chamber having a soundproofing / sound absorption structure with a sound absorbing material disposed between the two, a pipe through which air conditioning liquid passes all or part of the wall and ceiling, and an internal space of the porous metal plate It arrange | positions so that it may contact | abut to the outer surface on the opposite side directly or through another member.

  The invention of claim 2 embodies claim 1, and in the present invention, the wall and the ceiling are each composed of a plurality of panels, and each panel is between an outer plate and an inner plate. The sound absorbing material is arranged in a laminated structure, and the pipe is embedded in the sound absorbing layer of all or some of the multiple panels.

  According to a third aspect of the present invention, in the second aspect, the group of the ceiling and wall panels are arranged in parallel, and a connecting frame having an H-shaped cross section is arranged between the adjacent panels. The panel is fitted in the groove of the connecting frame.

  The invention of claim 4 is the shape of a quadrangle in plan view having four walls in claim 2 or 3, and the corner portion where the adjacent walls are connected is constituted by a corner panel bent at a right angle in plan view. Yes.

  According to a fifth aspect of the present invention, in the panel-type sound insulation chamber according to the second to fourth aspects, a metal inner frame for holding the pipe against the inner surface plate is disposed between the outer surface plate and the inner surface plate. The inner frame is joined to the outer plate and the inner plate.

  As a sound absorbing structure of the sound insulation chamber, there is one provided with a mountain-shaped sound absorption projection in the room, which is particularly effective when absorbing sound having a long wavelength. Claim 6 applies to this structure. That is, the invention according to claim 6 is the sound absorbing protrusion having a mountain-shaped cross section formed by projecting the inner surface plate and the sound absorbing material toward the inner space on one or both of the wall and the ceiling according to claim 1. Are formed, and the pipe is built in all or a part of the plurality of sound absorbing projections.

  In the present invention, while the walls and ceiling have an external sound insulation / internal sound absorption structure, the air conditioning in the room (internal space) is a radiant air conditioning system that uses liquids, so it is high without generating sound due to the air conditioning. Silence can be achieved. Moreover, since it is a radiation air-conditioning system, the room can be air-conditioned evenly.

  When the wall and the ceiling are constituted by panels as in claim 2, there are advantages that the assembly is easy and the sound insulation chambers of various sizes can be easily accommodated. Further, when the configuration of claim 3 is adopted, the sound insulation chamber can be easily assembled using the connecting frame having an H-shaped cross section, and the connecting frame also functions as a joint for filling a gap between adjacent panels. Therefore, the light shielding property can be ensured.

  When the structure of claim 4 is adopted, a corner post is not required, so that not only the appearance is refreshing and the appearance is good, but also the sound insulation and sound absorption properties are not lowered at the corner, so that high sound insulation performance and Sound absorption performance can be maintained.

  If the structure of Claim 5 is employ | adopted, since the outer surface board and the inner surface board are connected by the inner frame, the rigidity of a panel can be improved. For this reason, the dimensional accuracy of the sound insulation chamber can be improved and the appearance can be improved. Further, even when the sound insulation room is constructed with the panel itself as a strength member, the sound insulation room can have a robust structure.

  When applied to a structure having a sound-absorbing protrusion as in claim 6, since the surface area of the wall or ceiling is larger than when it is flat, the heat transfer area of the inner surface plate (porous metal plate) is also significantly increased. For this reason, high air conditioning performance can be ensured.

(1). First Embodiment Next, an embodiment of the present invention will be described. First, the first embodiment shown in FIGS. 1 to 5 will be described. As shown in FIG. 1 (A), the sound insulation chamber 1 of the present embodiment has a rectangular and large box shape, and is an independent facility inside a building having a wall W and a floor (ceiling slab) F. It is installed as.

  The sound insulation chamber 1 has a rectangular parallelepiped appearance, and thus has four wall portions. Each wall part is comprised by arranging the vertically long wall panel 2 in parallel in the horizontal direction, and the door 3 is provided in one wall panel 2. As indicated by the alternate long and short dash line, it is also possible to provide a window 4 on an arbitrary wall panel 2.

  When the wall panel 2 is rectangular, it can be arranged in a horizontal posture and stacked in multiple stages, but the vertically long posture is superior in strength. When the height of the sound insulation chamber 1 is higher than the height of the wall panel 2, the wall panels 2 may be stacked in multiple stages. In this case, from the viewpoint of the rigidity of the sound insulation chamber 1, FIG. As shown in the figure, it is preferable to combine the high and low ones so that the height of the wall panels 2 adjacent to each other on the left and right are different from each other.

  The ceiling part is configured by horizontally arranging ceiling panels 5 having the same shape and size as the wall panel 2 in parallel. In the example shown in the figure, the ceiling panel 5 is constituted by only one row, but in the case of the large sound insulation room 1, it can be arranged in a plurality of rows.

  As shown in FIG. 2A, the panels 2 and 5 are disposed between the outer plate 6 exposed outside the sound insulation chamber 1, the inner plate 8 exposed in the internal space 7 of the sound insulation chamber 1, and the both. The sound absorbing material 9 is a basic element. The outer surface plate 6 is made of a metal plate such as a steel plate or a stainless steel plate and has no holes. On the other hand, the inner surface plate 8 is made of a punching metal in which a large number of small holes 8a are formed in a steel plate or a stainless steel plate. As the sound absorbing material 9, for example, inorganic glass wool is used, but a metal nonwoven fabric or the like can also be used. It is also possible to stack materials of different materials, or to stack materials of the same material with different densities.

  In the embodiment shown in FIG. 2, the four circumferences of the panels 2 and 5 are configured by a channel-shaped outer frame 10, and the outer plate 6 and the inner plate 8 are fixed to the outer frame 10 by spot welding or the like. Although the outer frame 10 opens outward, the outer frame 10 may be open inward. Moreover, the outer frame 10 can use various steel materials (or a sheet metal processed product) such as a square steel pipe and an H-shaped steel.

  A pipe 11 through which water (liquid for air conditioning) flows is arranged in a part or all of the group of the ceiling panel 5 and the wall panel 2. The pipe 11 may be made of metal, but is usually made of resin (or a composite pipe of resin and metal). The pipe 11 is wrapped with a sound absorbing material 9. As shown in FIG. 4, the pipe 11 is bent in a zigzag manner so as to extend in the longitudinal direction of the panels 2 and 5, and overlaps the inner surface plate 8 from the outside. For this reason, heat is exchanged with the liquid of the pipe 11 through the inner surface plate 8 with the heat source (person) in the internal space 7 of the sound insulation chamber 1. Thereby, air conditioning of the internal space 7 of the sound insulation room 1 is performed.

  As shown in FIG. 2, a plurality of inner frames 12 extending long so as to cross the pipe 11 are arranged between the outer surface plate 6 and the inner surface plate 8 at an appropriate interval. The inner frame 12 has a lip 12 a that overlaps the outer surface plate 6 and a lip 12 b that overlaps the inner surface plate 8, and has a U-shaped cross-sectional shape. A notch 13 is formed. A constricted portion may be provided in the notch 13 so that the pipe 11 can be forcibly fitted.

  The inner frame 12 is previously fixed to the outer surface plate 6 by spot welding or the like. When assembling the panels 2 and 5, as shown in FIG. 2B, after placing the outer surface plate 6 on a table or the like with the outer surface plate 6 turned upside down, the sound absorbing material 9 is stacked on the outer surface plate 6, A procedure is adopted in which the pipe 11 is fitted into the inner frame 12 and then the inner surface plate 8 is overlapped and fixed to the outer surface plate 6 and the inner frame 12 by spot welding or the like.

  In the example shown in FIG. 3, the outer frame 10 of FIG. 2 is not used, and the outer frame plate 6 a facing the inner surface plate 8 is bent around the outer periphery plate 6, while the inner surface plate 8 has An inner frame plate 8a located inside the outer frame plate 6a of the outer surface plate 6 is bent and formed. That is, the outer surface plate 6 and the inner surface plate 8 are configured in a tray shape, and both are fitted together. Although not shown, the inner frame 12 is also provided in this example.

  The pipes 11 of the adjacent panels 2 and 5 are connected by a flexible joint pipe 17 through a joint 16 as shown in FIG. 3A, both ends of the pipe 11 are located on the same side, and in FIG. 3B, both ends of the pipe 11 are located on opposite sides. When male and female connectors are provided on the end surfaces of the panels 2 and 5 and the panels 2 and 5 are laid, the male connector of one panel 2 and 5 and the female connector of the other panel 2 and 5 are connected. It is also possible to configure.

  The extent to which the pipe 11 is provided in the group of the panels 2 and 5 may be selected according to the heat generation amount (number of workers) generated in the internal space 7 of the sound insulation chamber 1. Usually, it is not necessary to provide the pipe 11 on all of the ceiling panel 5 and the wall panel 2, and it can be said that it is often sufficient to provide the pipe 11 on all or part of the ceiling panel 5. When the pipe 11 is provided on the wall panel 2, as shown in FIG. 1B, if the joint 16 is provided on the upper end surface of the wall panel 2, the exposure of the joint pipe 17 can be suppressed, so that the appearance is good. There is.

  As illustrated in FIG. 5, the floor has a structure in which a floor board 18 is supported by a joist 19, and a space between the floor board 18 and the floor surface is filled with a sound absorbing material 9 such as glass wool. Yes. A channel-shaped ground rail (ground frame, baseboard) 19 is disposed outside the floor, and the wall panel 2 is placed on the ground rail 19. Although the ground rail 19 has a groove shape with a downward opening, the ground rail 19 can be arranged in an upwardly opening posture. When the ground rail 20 is in an upward opening posture, the lower end portion of the wall panel 2 may be fitted therein. The wall panel 2 in FIG. 5 has the structure shown in FIG.

  As shown in FIG. 6A, the adjacent wall panels 2 are connected by a H-shaped wall connection frame (joint frame) 21 and the adjacent ceiling panels 5 are connected by a H-shaped wall connection. They are connected by a frame 22. That is, the connecting frames 21 and 22 have two grooves opened back to back, and the adjacent panels 2 and 5 are placed in the same posture by fitting the end portions of the adjacent panels 2 and 5 into the grooves. It is connected. In FIG. 6, the panels 2 and 5 are displayed in the form of FIG.

  An L-shaped corner wall panel 2 ′ in plan view is used at a corner portion between two adjacent wall portions of the wall panel 2. The corner wall panel 2 ′ of the present embodiment does not include the pipe 11, but when the pipe 11 is incorporated to provide an air conditioning function, the pipe 11 is preferably provided separately in two orthogonal portions (that is, It is preferable that the pipe 11 is not bent at a right angle in a plan view but only bent in one plane.)

  When the pipe 11 is provided on the wall panel 2, it may be formed in a zigzag shape in the horizontal direction as shown in (C), or may be formed in a zigzag shape in the vertical direction as shown in (D). When both the ceiling panel 5 and the wall panel 2 have an air conditioning function, the water supply system of the ceiling panel 5 and the water supply system of the wall panel 2 may be separated, or the ceiling panel 5 and the wall panel 2 may be separated. It is also possible to flow from the wall panel 2 to the ceiling panel 5.

  The wall connecting frame 21 and the ceiling connecting frame 22 are connected by a metal fitting (not shown). As shown in FIG. 1, an upper beam 23 that is long in the horizontal direction is disposed at the boundary between the ceiling and the wall, and the upper end of the wall connecting frame 21 and both ends of the ceiling connecting frame 22 are connected to the main beam 23. By doing so, it is also possible to constitute the frame of the sound insulation chamber 1 by the respective frames 21 and 22 and the upper beam 23 (and the ground rail 20).

  When the upper beam 23 is not used, the end of the ceiling panel 5 may be placed on the wall panel 2 as shown in FIG. When this configuration is adopted, not only is the support strength of the ceiling panel 5 excellent, but there is also an advantage that the joint between the ceiling and the wall can be sound-insulated and sound-absorbed (in terms of sound insulation and sound absorption, FIG. The structure of B) can also achieve a high effect.) Note that a slight gap may occur in the connecting portion of each member, but this gap may be closed with a sealing member such as a softener or an adhesive.

  In FIG. 6E, an L-shaped reinforcing frame 24 is overlapped on the edge of the adjacent ceiling panel 5 and the reinforcing frame 24 is fixed to each ceiling panel 5 with screws or the like. Then, the robustness of the sound insulation chamber 1 can be improved without using the main beam 23.

  Since the inside of the sound insulation chamber 1 is hermetically sealed, ventilation is required. Therefore, as shown in FIG. 1A, a ventilation device 25 is provided at one corner of the upper surface of the ceiling. Needless to say, a water pipe and a drain pipe for circulating water through the pipe 11 are arranged outside the sound insulation chamber 1, and the water pipe and the drain pipe are connected to the heat exchange unit. .

  The present embodiment has the above-described configuration, and the entire outer surface of the sound insulation chamber 1 is made of a metal plate. Therefore, the sound entry from the outside is blocked and high sound insulation is exhibited. On the other hand, the sound generated inside the sound insulation chamber 1 is absorbed by the sound absorbing material 9 through the inner surface plate 8 having a large number of holes. And since the water for an air conditioning flows through the inside of the pipe 11 silently, the inside can be hold | maintained in a high silence state, although it is the sound insulation room 1 which has an air-conditioning function. Moreover, since the panels 2 and 5 which comprise a wall part and a ceiling part are the same basic structures except the presence or absence of the pipe 11, it can reduce a cost by making a member common.

  When the inner frame 12 is provided as in the present embodiment, the inner frame 12 serves as a heat transfer member (heat sink), which is an advantage that air conditioning performance can be improved. When the inner frame 12 is made of a punching metal, there is an advantage that a decrease in sound absorption can be suppressed.

  In this embodiment, the floor is composed of the floor plate 18 without holes. However, when the floor needs to have a high sound absorption function, the floor plate 18 is composed of punching metal having a large number of holes. Or you can put a carpet on it.

(2) Other Embodiments In the second embodiment shown in FIG. 7A, the pipe holder 26 that holds the pipe 11 is fixed to the inner surface plate 8 by spot welding or the like. The pipe holder 26 is made of a metal plate, has a constricted portion, and is fitted to the pipe 11 by being pushed against elasticity. The pipe holder 26 may have a length that extends over substantially the entire blood length of the pipe 11, or may be intermittently disposed along the longitudinal direction of the pipe 11.

  In this way, when the pipe holder 26 is used, the inner frame 12 is not necessary, so the outer surface plate 6 and the inner surface plate 8 may be connected by a plurality of rods or strips arranged at appropriate intervals. As indicated by the alternate long and short dash line in (A), it is possible to provide the pipe holder 26 with a flange portion 26 a that overlaps the inner surface plate 8. In this case, since the pipe holder 26 serves as a heat sink that expands the heat transfer area, there is an advantage that the air conditioning performance can be improved (the pipe holder 26 is composed of a perforated plate having the same structure as the inner surface plate 8, If the positions of the holes of the holder 26 and the inner surface plate 8 are aligned, it is preferable because the sound absorption is not hindered.

  In the third embodiment shown in FIG. 7B, the inner frame 12 has a U-shape opening toward the inner surface plate 8, and the inner frame 12 is made of punching metal. In this example, since the inner frame 12 has an annular structure, the dimensional accuracy of the panels 2 and 5 can be improved by correcting the warpage of the outer plate 6 and the inner plate 8.

  The fourth embodiment shown in FIG. 8 is applied to claim 6, and a large number of sound-absorbing protrusions 28 having a triangular cross section (triangle) are formed on the sound insulating outer plate 17 constituting the outer surface of the wall and ceiling of the sound insulating chamber 1. doing. The sound absorbing material 9 extends in the horizontal direction in the case of a ceiling, and extends in the horizontal direction or the vertical direction in the case of a wall.

  The sound absorbing projection 28 has an inner surface plate 8 exposed in the inner space 7 of the sound insulation chamber 1, and the sound absorbing material 9 is disposed between the inner surface plate 8 and the outer surface plate 27. The air conditioning pipe 11 is disposed inside the sound absorbing projection 28 in contact with the inner surface plate 8. In each sound absorption projection 28, the pipe 11 is bent in a zigzag manner, and the pipes 11 of the adjacent sound absorption projections 28 are connected by a joint (not shown). The outer plate 27 may be made of a metal plate such as a steel plate. The height of the sound-absorbing protrusion 28 varies depending on the wavelength of the sound to be absorbed, but can be set to, for example, about several tens cm to 1.5 m.

  In this type of sound absorbing structure, since the surface area of the inner surface plate 8 is increased, both the sound absorbing performance and the air conditioning performance can be significantly improved. It is also possible to change the height of the sound absorption protrusions 28 between the wall part and the ceiling part, or arrange the sound absorption protrusions 28 having different heights on the wall part and the ceiling part.

  The present invention can be embodied in various ways other than the above-described embodiment. For example, the porous metal layer that constitutes the inner surface of the ceiling or wall can be composed of a metal nonwoven fabric.

  The present invention can be manufactured by actually applying to a sound insulation chamber. Therefore, it can be used industrially.
