JP 2001-140312 A

  However, piping along the outer wall surface deteriorates the appearance of the building, particularly when the piping part faces the street, there is a problem that the cityscape is damaged. In addition, there are many construction sites where buildings constructed in narrow areas such as urban areas and commercial areas cannot secure a sufficient space between adjacent buildings and cannot provide a scaffold for piping work. Under such circumstances, when piping work is performed without a scaffold, there is a problem that the work efficiency is remarkably lowered and there is a risk in construction.

  The present invention basically accommodates a pipe body that is piped between an external equipment device installed on the roof and an indoor equipment device inside the exterior plate and in the thickness area of the piping panel frame. Therefore, it is an object of the present invention to provide an outer wall structure that can perform piping work safely and efficiently even if a scaffold space cannot be secured between adjacent buildings without deteriorating the appearance of the building.

  In order to achieve the above object, in the invention according to claim 1, an outer wall panel formed by fixing an exterior plate to a panel frame body including an outer peripheral frame and attached to a building structure to form an outer wall, and the panel A pipe panel that is fixed to a pipe panel frame that is the same thickness as the frame and that is formed narrower than the outer wall panel and is attached to the building structure between the outer wall panels; The piping panel accommodates a pipe body that is piped between an external equipment device installed on the roof and an indoor equipment device inside the exterior plate and in the area of the thickness of the piping panel frame. Features.

  In the invention according to claim 2, the pipe panel frame has a tube insertion part formed by cutting out a part of the upper and lower frame, and the pipe passes through the pipe insertion part and extends vertically. The piping panel in the invention according to claim 3 is covered with an insulating board having fire resistance on the indoor side of the piped body, and the insulating board is continuously provided on the indoor side of the outer wall panel and the piping panel. The fireproof layer is formed and the interior base is formed, and the piping panel of the invention according to claim 4 is characterized in that a heat-insulating board having fire resistance is further provided between the exterior material and the tubular body. To do.

  Since the invention according to claim 1 does not attach equipment piping to the outer surface of the outer wall, it is not necessary to set up a scaffold for piping work on the outer periphery of the building. As a result, it is possible to efficiently and safely carry out construction work in a narrow area where there is no margin space between adjacent buildings. On the other hand, since the equipment piping is covered with an exterior plate, deterioration and freezing of the piping are suppressed, trouble such as liquid leakage and rupture is reduced, maintenance is facilitated, and the piping is hidden from the outside, so the appearance of the building is improved. improves. And since a piping panel is formed in the same thickness as an outer wall panel, a piping panel can be arrange | positioned in the arbitrary positions between outer wall panels, and a piping path | route can be set freely. Accordingly, the equipment can be installed in an optimum location in consideration of the use state, the plan, etc. without being restricted by piping, and efficient operation and comfortable use are possible.

  If the pipe insertion part formed by notching a part of the upper and lower frame bodies is provided in the piping panel frame body as in the invention according to claim 2, the pipe body passes straight through the pipe insertion part. Piping can be performed, improving workability and forming the shortest piping path.

  Like the invention which concerns on Claim 3, when the indoor side of an outer wall panel and a piping panel is continuously covered with the heat-insulating board which has fire resistance, the outer wall of a fireproof structure building or a semi-fireproof structure building is selectively constructed. be able to. In addition, most of the pipes are placed inside the piping panel, so there is little buffering with the heat insulation board, and the same level of fireproof specifications can be arbitrarily constructed according to the building specifications while using the same piping panel. it can.

  Further, in the invention according to claim 3, even when the heat insulating board that covers a pipe panel on the indoor side is thin due to the thickness of the pipe body, a portion of the pipe body protrudes from the pipe panel to the indoor side. Since the insulation board between the two compensates for this, the necessary and sufficient fire resistance is obtained as a whole.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the outer wall structure 1 includes an outer wall panel 6 and a piping panel 8 disposed between the outer wall panels 6.

  As shown in FIGS. 2 and 3, the outer wall panel 6 is provided with a reinforcing bar (not shown) on the inner side of an outer frame 2 </ b> A in which a lightweight frame steel is used and a horizontal frame material is framed in a rectangular shape. A single-sided panel in which an exterior plate 3 is fixed to the outdoor side of a steel panel frame 2 that is formed to span is used. On the other hand, the pipe panel 8 is fixed to the pipe panel frame body 7 having a substantially vertical groove shape formed by bending a long steel plate in the vertical direction into a U-shape with a cross-sectional lip, and fixing the exterior plate 3 having the same thickness as the outer wall panel 6. Formed. As shown in FIGS. 2 and 4, upper and lower frame bodies 8 </ b> A in which a tubular body insertion portion 12 is formed by cutting out the indoor side into a rectangular shape are provided at the upper and lower ends of the piping panel frame body 7.

  The height of the outer wall panel 6 and the piping panel 8 is approximately the same as the floor height of the building, for example, about 2500 to 3500 mm, and 2900 mm in this embodiment. Further, the width of the outer wall panel 6 is formed so as to have a so-called modular coordination, for example, when the building module size is 900 mm, it is formed to a size such as an integral multiple of 1800 mm, 2700 mm, 3600 mm, and the like. The piping panel 8 is formed in a size of 450 mm, which is half of the module size.

  In this embodiment, the exterior plate 3 uses an ALC panel having a thickness of 50 mm. Other than this, the exterior board 3 is a ceramic system such as calcium silicate board and flexible board, a metal system in which a foamed resin layer is sandwiched between a steel plate and an aluminum plate, a plywood, a wood cement board, and a wood system in which a wood chip cement board is waterproof-coated. It is also possible to use various siding boards.

  Thus, a plurality of outer wall panels 6 are installed side by side without vertical and horizontal gaps while incorporating the piping panel 8 into the piping location. Then, by using a known outer wall fastener (not shown), the outer wall 5 of the so-called curtain wall construction method is formed by attaching it to the outdoor side of the building structure 4 constituting the main building structure. In addition, the building structure 4 of this embodiment employs a steel frame structure that is assembled with a column and a beam 21 made of I-shaped steel between the columns.

  The piping panel 8 includes a pipe that is piped between an external equipment device 9 installed on the rooftop and an indoor equipment device 10 inside the exterior panel 3 and within the thickness of the piping panel frame 7. The body 11 is accommodated. In this embodiment, as shown in FIG. 1, from the outdoor unit 9A of the air conditioner attached to the rooftop, the rooftop slab 22 is inserted to reach the ceiling space on the uppermost floor and through the piping hole of the beam 21. A duct for circulating refrigerant extends toward the outer wall 5 and further extends downward in the piping panel 8 to the indoor unit 10A fixed to the wall in the indoor space on the lower floor.

  Thus, since the pipe body 11 which continues indoors from a rooftop is accommodated in the piping panel 8 and is piped on the indoor side of the exterior board 3, it is not necessary to attach the pipe body 11 to the outer side of an outer wall. Therefore, it is not necessary to provide a work platform for piping along the outer wall, so that piping work can be performed efficiently and efficiently even in a narrow area with no space between adjacent buildings such as urban areas and urban areas. It can be done safely. In addition, since the equipment piping is covered with the exterior plate 3 and is not exposed, deterioration and freezing of the tube body 11 can be prevented, troubles such as liquid leakage and rupture are reduced, and maintenance is facilitated. Because it is hidden by 3, the appearance of the building is enhanced. Furthermore, since the piping panel 8 is formed to have the same thickness as the outer wall panel 6, the piping panel 8 can be installed at an arbitrary position between the outer wall panels 6, so that the equipment is most suitable for use conditions and construction conditions. It can be operated efficiently and can be used comfortably.

  Further, since the pipe panel 8 is provided with the pipe insertion portion 12 in the upper and lower frame bodies 8A as described above, the pipe body 11 does not need to meander around an obstacle and can be piped straight up and down. As a result, the efficiency of the piping work can be improved and the piping can be performed with the shortest route, so that heat loss can be reduced and the energy efficiency can be increased.

  The indoor side of the outer wall panel 6 and the piping panel 8 is covered with a continuous fireproof heat insulating board 13. In the present embodiment, the heat insulating board 13 is a gypsum board 23 with heat insulating material in which a polyethylene foam 23B is laminated on a moisture-proof gypsum boat 23A.

  As shown in FIGS. 3 and 4, the tubular body 11 of this embodiment has a part of the indoor side that slightly protrudes from the piping panel frame 7 to the indoor side. A spacer 24 using a wooden crosspiece is attached to the lip portion 8B, and the gypsum board 23 with heat insulating material is attached thereon. Accordingly, the outer wall panel 6 is provided with an additional heat insulating board 13 using the heat insulating material 25 having the same thickness as the spacer 24 between the gypsum board 23 with the heat insulating material. A high-performance heat insulating layer is formed by laminating the gypsum board with heat insulating material 23. Further, in the piping panel 8, in order to supplement the heat insulating performance of the heat insulating material 25 of the outer wall panel 6, an auxiliary material using the heat insulating material 26 between the pipe body 11 and the exterior plate 3 is provided inside the pipe panel frame 7. A heat insulating board 13 is provided.

  Thus, in this embodiment, the refractory layer 14 that is continuous on the indoor side of the outer wall panel 6 and the piping panel 8 is formed by the gypsum board 23 with the heat insulating material and the heat insulating materials 25 and 26. Therefore, by appropriately selecting the thickness and material of these heat insulating materials and the like, it is possible to selectively construct an outer wall such as a fireproof structure building or a semi-fireproof structure building according to the use area of the site. Moreover, even if there is a partial protrusion, the piping part is mostly piped inside the piping panel 8, so it does not buffer greatly with the heat insulating board 13, and therefore the same type of piping panel 8 is used. However, according to the specifications of the building, a fireproof specification of a necessary level can be arbitrarily constructed, and the construction period can be shortened and the cost can be reduced.

  In addition, as in this embodiment, when a relatively large-diameter tube 11 is accommodated, and a part of the tube 11 protrudes from the piping panel to the indoor side, and the heat insulating board on the indoor side of the piping panel becomes thin, the exterior material If this is supplemented by the heat insulating material 26 inserted between the pipe and the tube, it is preferable in that the necessary and sufficient fire resistance can be obtained as a whole.

  In addition, the heat insulating material laminated | stacked on the said heat insulating materials 25 and 26 and the moisture-proof gypsum board 23 is preferable at the point which can improve fireproof performance, if a polyethylene foam whose ignition temperature is about 480 degree | times is used. However, other than this, inorganic fiber heat insulating materials such as glass wool and rock wool, wood fiber heat insulating materials such as cellulose fiber and insulation board, foamed resin heat insulating materials such as foamed polystyrene, hard urethane, phenol, or aluminum for these heat insulating materials It is also possible to use a laminated heat insulating material with a foil attached thereto.

  The refractory layer 14 forms an interior base at the same time, and an interior finish material is adhered to the indoor side. As interior finish materials, embossed plain wallpaper, printed embossed wallpaper, foam wallpaper, silk wallpaper, etc. Paper wallpaper including wallpaper, wood-based wallpaper, wood-based wallpaper including cork sheet wallpaper, inorganic wallpaper, and the like are used. Inorganic wallpaper is a paper that has been decorated with a flame-retardant surface and a surface layer of cold chill, etc., backed by an inorganic base material such as cloth-like glass fiber or foil-like aluminum hydroxide. preferable.

  2 and 3, the lower portion of the piping panel 8 is fixed to the beam 21 using a dedicated fastener 27. The dedicated fastener 27 has a rectangular frame body 28 surrounding the pair of tube bodies 11, and a fireproof joint material 29 is filled in a gap between the rectangular frame body 28 and the tube body 11.

  FIG. 5 illustrates another embodiment. Hereinafter, different contents will be described, and other than that, only the same reference numerals are given to the main components shown in the figure. The piping panel 8 of this embodiment is a lightweight channel steel extending vertically at the inner center of the outer peripheral frame 7A of the piping panel which is a frame of the vertical frame 7V and the horizontal frame 7H each using a lightweight channel steel that opens inward. A piping panel frame 7 is used that spans the reinforcing bars 7R used.

  The piping panel 8 is provided with a tubular body insertion portion 12 including an elliptical hole 30 in the horizontal frame 7H, and a short-angle cylindrical support portion 31 continuous with the elliptical hole 30 is fitted between the flanges of the horizontal frame 7H. Fixed. In addition, the pipe panel 8 accommodates two pipe bodies 11 extending vertically with the reinforcing bar 7R interposed therebetween, and the pipe bodies 11 are connected to the upper and lower parts of the pipe panel 8 through the elliptical hole 30 and the support portion 31 continuously. And then piped. Thus, since the pipe body 11 piped up and down in the piping panel 8 is stably supported by the support portion 31, there is no displacement, and liquid medium, hot water, etc. flow through the pipe. Is preferable in that the tube body 11 is prevented from generating vibration.
