[0001]
BACKGROUND OF THE INVENTION
  In the present invention, a shutter curtain, a panel curtain, a door panel, a partition, an overhead door, or a wall of a building for partitioning a space is provided with a function of fire prevention, heat insulation, cooling or heating.Space partition deviceAbout.
[0002]
[Prior art]
  In general, a fire shutter is known as a plate-like member having a heat treatment function and a fire prevention system. This fire-proof shutter includes a shutter curtain in which a large number of slats are rotatably connected. Each slat is fire resistant. The shutter curtain constituted by the slats blocks the passage, thereby blocking smoke and flames in the event of a fire.
[0003]
[Problems to be solved by the invention]
  However, with the fire shutter having the above-described configuration, it is possible to block smoke and flames in the event of a fire, but it is difficult to completely block the heat accompanying the fire. That is, when one side of the fire shutter is exposed to a fire flame, the entire fire shutter becomes hot. As a result, the other side of the fire shutter also becomes hot and emits radiant heat, and the vicinity of the other side of the fire shutter is affected by the radiant heat. For example, when approaching a fire shutter, it is hot due to radiant heat, and therefore, when an evacuee evacuates, there is a problem that it is difficult to pass near the fire shutter.
[0004]
  The present invention has been made in view of such problems, and has reduced harmful effects caused by radiant heat.Space partition deviceThe purpose is to provide.

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, according to the present inventionSpace partition device etc.Will be described with reference to the accompanying drawings.
[0007]
[First Embodiment]
  In the present embodiment, a panel shutter 1 will be described as an example of a plate-like member having a heat treatment function. As shown in FIG. 2, the panel shutter 1 mainly includes a panel 2, a guide rail 3, a lifting mechanism 4, and a control panel 5.
[0008]
  The panel 2 is constituted by a rectangular flat plate. A plurality of the panels 2 (three in the present embodiment) are arranged, and these are combined to form a plate-like member that partitions the space. On both end surfaces in the longitudinal direction of each panel 2, there are provided a locking piece 6 that locks on a pulling chain 22 described later, and a guide roller 7 that fits in the guide rail 3 and guides the vertical movement of the panel 2. Yes.
[0009]
  As shown in FIG. 1B, stepped portions 2A and 2B are formed on the upper and lower ends of the panel 2 so that the front and rear are reversed. The stepped portion 2A at the upper end of the panel 2 is formed such that the outside protrudes upward. The step 2B at the lower end of the panel 2 is formed so that the inside protrudes downward. Thus, when the two upper and lower panels 2 are overlapped in the guide rail 3, the stepped portion 2B of the upper panel 2 and the stepped portion 2A of the lower panel 2 are engaged with each other to form a plate member. .
[0010]
  A seat plate 8 is attached to the lower panel 2 of the three panels 2 as shown in FIG. A lower frame 9 for receiving the seat plate 8 is provided on the floor surface.
[0011]
  As shown in FIGS. 3 and 4, the panel 2 is configured as a hollow plate member whose inside is sealed by a front side plate portion 2 </ b> C and a back side plate portion 2 </ b> D that face each other. Inside the panel 2, a plurality of horizontal plates 11 extending to the side walls 2E and 2F at the left and right ends are provided over the entire region from the upper end to the lower end. The left and right ends of each horizontal plate 11 are alternately open between the side walls 2E and 2F. As a result, the injected fluid flows to the side wall 2E at one end, then falls to the lower horizontal plate 11 and flows to the side wall 2F at the other end. As a result, the fluid flows left and right in the panel 2 and comes into contact with the entire inner side walls of the front side plate portion 2C and the back side plate portion 2D. An inlet 12 is provided at one upper end portion (right upper end portion in the drawing) of the back side plate portion 2D, and a discharge port 13 is provided at the other lower end portion (left lower end portion in the drawing). This panel 2 is comprised with the synthetic resin etc. which were excellent in aluminum, stainless steel, iron, heat resistance.
[0012]
  As shown in FIG. 3, the guide rail 3 is disposed on both sides of the panel 2 and supports the panel 2 from the left and right sides. The cross-sectional shape of the guide rail 3 is substantially U-shaped, and the left and right ends of the panel 2 are inserted into and supported by the guide rail 3. The guide rail 3 is embedded in both side walls of the entrance and the passage.
[0013]
  As shown in FIGS. 1 and 3, a cooling water supply pipe 15 is disposed in the vicinity of the guide rail 3 and at a position facing the panel 2 in a state of being lowered to partition the space. The cooling water supply pipe 15 is arranged in the vertical direction along each panel 2 and the guide rail 3 in the lowered state. The cooling water supply pipe 15 is provided with a branch pipe portion 16 for allowing the cooling water flowing inside to flow out in the lateral direction. The branch pipe portions 16 are provided at three locations corresponding to the inlets 12 of the panels 2 in the lowered state. The distal end of each branch pipe portion 16 is provided at a position facing the inlet 12 of each panel 2 in the lowered state, and the cooling water flowing out from the distal end flows into the panel 2 from the inlet 12. It is like that.
[0014]
  The cooling water supply pipe 15 is connected to a cooling water supply system (not shown). This cooling water supply system is controlled by the control panel 5 so that cooling water is supplied when a fire occurs. Furthermore, the cooling water supply system also serves as a water supply facility for the sprinkler or water mist spraying device, and the operation of the sprinkler and the like and the supply of cooling water to the panel 2 are interlocked. The water mist refers to water particles having a fine particle diameter compared to water discharge particles such as sprinklers. For example, it means water particles having a Sauter average particle diameter of 1000 μm or less, desirably 40 to 400 μm.
[0015]
  Further, as shown in FIG. 5, drainage masses 18 are respectively provided at positions facing the discharge ports 13 of the respective panels 2 in a state of being lowered along the guide rails 3. In FIG. 5, only the drainage mass 18 corresponding to the lowermost panel 2 is shown. Each drainage mass 18 is connected to a drainage pipe 19 arranged to extend to the outside. Accordingly, the drainage mass 18 receives the cooling water flowing out from the discharge port 13 and is drained to the outside by the drainage pipe 19.
[0016]
  As shown in FIG. 2, the lifting mechanism 4 includes an opening / closing machine 21 formed of a drive motor, a lifting chain 22 that is lifted while being locked to the locking pieces 6 of the panels 2, and a lifting sprocket 23 that supports the lifting chain 22. The horizontal guide rail 24 is provided. The pulling chain 22 is locked with the locking pieces 6 at a fixed interval (interval slightly larger than the interval between the adjacent locking pieces 6 of each panel 2 lowered along the guide rail 3). Yes. Accordingly, the panel 2 is pulled up or extended along the guide rail 3 and the horizontal guide rail 24 by the lifting chain 22 being pulled up or drawn out by the switch 21.
[0017]
  The control panel 5 controls operations such as raising and lowering the panel 2 and supplying cooling water when a fire occurs. The detection of fire occurrence is performed by a sensor provided independently, notification from another fire detection device, or the like. A push button switch 25 is provided in the vicinity of the guide rail 3. The push button switch 25 can be operated to raise and lower the panel 2.
[0018]
  In addition, although the horizontal plate 11 etc. which are directly in contact with both the front side plate portion 2C and the back side plate portion 2D of the panel 2 usually become a heat bridge, here, the front side plate portion 2C of the horizontal plate 11 etc. Since the member that is in direct contact with the back plate 2D is in contact with the cooling water in the fluid passage, it is prevented from becoming a heat bridge, and between the front plate 2C and the back plate 2D. This prevents direct heat transfer. This configuration is the same in other embodiments and modifications described later.
[0019]
[Operation]
  The panel shutter 1 configured as described above is pulled up and pulled out under the control of the control panel 5.
[0020]
  In the case of the panel shutter 1 used for fire prevention, it is normally opened and is closed by detecting fire.
[0021]
  When a fire occurs, the control panel 5 operates based on a signal from a sensor, a fire detection device, etc., and the panel 2 is extended. The feeding operation of the panel 2 is performed as shown in FIGS. 6D to 6A. Specifically, the pull-up chain 22 is fed out by the opening / closing machine 21, and each panel 2 locked thereto is fed out. At this time, the panel 2 sequentially moves to the guide rail 3 side along the horizontal guide rail 24, and after being introduced into the guide rail 3, until the seat plate 8 of the lowermost panel 2 comes into contact with the lower frame 9. Be taken down. The next panel 2 is lowered until the lower step portion 2B is fitted to the upper step portion 2A of the lowermost panel 2. Similarly, the passage of the next panel 2 is shielded. This prevents flame and smoke from spreading along the passage.
[0022]
  Further, the cooling water supply system is operated, and the cooling water is supplied to the cooling water supply pipe 15. The cooling water supplied to the cooling water supply pipe 15 flows laterally from each branch pipe portion 16 and is poured into the inside from the inlet 12 of each panel 2. The cooling water flowing into the interior reciprocates while flowing to the left and right ends along each horizontal plate 11 and gradually flows to the lower end of the panel 2. Then, it finally flows out from the discharge port 13. The cooling water that has flowed out flows into the drainage mass 18 and is discharged to the outside through the drainage pipe 19. Thereby, inside each panel 2, cooling water will always flow in the whole area, and even if each panel 2 is heated with the heat accompanying a fire, the cooling water which flows inside absorbs the heat, Panel 2 is cooled. In particular, since the cooling water always flows through the panel 2, even if the panel 2 is heated by the flame, the heat is absorbed by the cooling water and discharged to the outside together with the cooling water. As a result, the panel 2 exposed to high heat due to flame can be efficiently cooled, and radiant heat is not transmitted to the opposite side of the panel 2.
[0023]
  When the panel 2 is pulled up, the push button switch 25 is pushed. Accordingly, as shown in FIGS. 6A to 6D, when the lifting chain 22 is supported by the lifting sprocket 23 and the like and pulled up by the opening / closing device 21, each panel 2 locked to the lifting chain 22 is used. Are pulled up along the guide rails 3 and supported one by one along the horizontal guide rails 24 in the horizontal direction, and are stored compactly.
[0024]
[effect]
  As described above, since the cooling water flow passage for flowing the cooling water is formed inside each panel 2, heat can be cut off together with the flame and smoke accompanying the fire.
[0025]
  As a result, it is possible to prevent harmful effects caused by radiant heat transmitted to the opposite side of the panel 2.
[0026]
[Second Embodiment]
  Next, a second embodiment of the present invention will be described with reference to FIGS.
[0027]
  Since the overall configuration of the panel shutter of the present embodiment is the same as that of the first embodiment, the same members are denoted by the same reference numerals and description thereof is omitted.
[0028]
  This embodiment is an example when the panel shutter is enlarged. When the panel shutter is enlarged, the panel is also enlarged. For this reason, the horizontal dimension of the panel increases, the vertical dimension increases, and the number of installed panels increases. For this reason, the strength of the configuration of the panel 2 of the first embodiment may be insufficient. In order to resolve this lack of strength, as shown in FIG. 7, a reinforcing plate 31 is provided in the middle of the horizontally elongated panel 30 (in the center in the figure). As shown in FIGS. 8 and 9, the reinforcing plate 31 is formed in an L-shaped cross section and is disposed in the panel 30 in the vertical direction. By providing the reinforcing plate 31 in the panel 30, the inside of the panel 30 is divided into left and right. When the inside of the panel 30 is divided by the reinforcing plate 31 in this way, the flow path of the cooling water is also blocked by the reinforcing plate 31, so that the flow path of the cooling water is formed for each divided internal space.
[0029]
  An inlet 32 and an outlet 33 are formed at the inlet / outlet of the cooling water flow path in each space divided by the reinforcing plate 31. That is, an inlet 32 is provided in each upper space of each panel 30 for each space divided by the reinforcing plate 31. On the lower side of the panel 30, a discharge port 33 is provided at a position aligned with the injection port 32. The inlet 32 and the outlet 33 are provided at positions where they are aligned with each other, so that when the panels 30 are stacked, they are fitted to each other. That is, when a plurality of panels 30 are stacked in the guide rail 3, the inlet 32 of the upper panel 30 is inserted into and fitted into the outlet 33 of the lower panel 30, and positioning between the upper and lower panels 30 is performed. In addition, the cooling water flow paths in the upper and lower panels 30 are connected. Thereby, the increase in the cooling water supply piping 15 etc. accompanying the increase in the number of installations, such as the inlet 32, is suppressed.
[0030]
  As shown in FIG. 10, the discharge port 33 of the lowermost panel 30 is provided not on the lower surface but on the horizontal wall surface. A drainage mass 34 and a drainage pipe 35 are provided at a position in the bottom of the guide rail 3 and facing the discharge port 33. Since the internal space of the panel 30 is divided into left and right by the reinforcing plate 31, the discharge port 33, the drainage mass 34 and the drainage pipe 35 are respectively provided on the left and right wall surfaces.
[0031]
  As shown in FIGS. 8 and 9, a horizontal plate 36 similar to the horizontal plate 11 of the first embodiment is provided in the panel 30 divided by the reinforcing plate 31, and the cooling water reaches the left and right end portions. While reciprocating, it flows through the entire space.
[0032]
  The cooling water supply pipe (not shown) does not have the branch pipe portion 16 of the first embodiment and is not passed through the guide rail 3. In the upper part of the guide rail 3, it is provided so as to face the two inlets 32 on the upper surface of the uppermost panel 30.
[0033]
[Operation]
  The panel shutter configured as described above operates as follows.
[0034]
  Since the overall operation of the panel shutter of the present embodiment is substantially the same as the operation of the panel shutter 1 of the first embodiment, only the operation of the characteristic part of the present application will be described here.
[0035]
  When a fire occurs, each panel 30 is lowered under the control of the control panel 5. Among the panels 30, the lowermost panel 30 is lowered until it comes into contact with the lower frame 9. Accordingly, the discharge ports 33 on both sides thereof are positioned facing the drainage mass 34 in the guide rail 3.
[0036]
  Next, the next panel 30 is continuously lowered along the guide rail 3 on the lowermost panel 30. The panel 30 overlaps the lower panel 30. At this time, the discharge port 33 of the upper panel 30 is inserted into the injection port 32 of the lower panel 30 and fitted. Thereby, each panel 30 is positioned with respect to each other and installed at a predetermined position, and the cooling water flow paths in the upper and lower panels 30 are connected. Further, the upper panel 30 is overlapped, the discharge port 33 is inserted into the injection port 32, all the panels 30 are positioned with respect to each other, and installed at a predetermined position. The cooling water flow path in the panel 30 is connected. At the same time, the space is partitioned (the passage is closed).
[0037]
  Next, the cooling water supply system is actuated to supply cooling water to the cooling water supply pipe, and is injected into the panel 30 from the inlet 32 of the uppermost panel 30. The injected cooling water flows left and right through the cooling water flow path in the panel 30, reaches the lower part while cooling the entire surface of the panel 30, and is discharged from the discharge port 33. The cooling water drained from the discharge port 33 is injected into the lower panel 30 from the injection port 32 in which the discharge port 33 is fitted.
[0038]
  This operation is repeated up to the lowermost panel 30, and the water is drained from the discharge port 33 on the lower side of the lowermost panel 30 to the drainage mass 34. The cooling water that has flowed into the drainage mass 34 is drained to the outside via the drainage pipe 35.
[0039]
  Thereby, the cooling water supplied from the cooling water supply pipe cools and drains the entire panel 30 while flowing left and right in all the panels 30. In this state, when one side of the panel 30 is heated to a high temperature by a flame caused by a fire, the cooling water constantly flowing in the panel 30 absorbs the heat and discharges it to the outside. As a result, the panel 30 can be efficiently cooled, and radiant heat is not transmitted to the opposite side of the panel 30.
[0040]
[effect]
  This also makes it possible to cut off heat as well as flames and smoke associated with fire, as in the first embodiment.
[0041]
  As a result, it is possible to prevent harmful effects caused by radiant heat transmitted to the opposite side of the panel 30.
[0042]
[Third Embodiment]
  Next, a third embodiment of the present invention will be described.
[0043]
  This embodiment is an example applied to a door of a building. As shown in FIGS. 11 and 12, the door 41 mainly includes a door frame 42 fitted in a doorway or a passage of a building, and a door plate 44 attached to the door frame 42 by a hinge 43 so as to be opened and closed. It is composed of
[0044]
  The door plate 44 mainly includes a surface material 45 that covers the entire front side, a back surface material 46 that covers the entire back side, a side material 47 that covers the entire outer peripheral edge, and a skeleton 48 formed inside the side material 47, It is comprised from the partition plate 49 provided in the horizontal direction at multistage. These are made of aluminum, stainless steel, synthetic resin having excellent heat resistance, or the like.
[0045]
  The partition plate 49 is configured in the same manner as the horizontal plate 11 of the first embodiment. That is, the partition plate 49 is provided in a plurality of stages over the entire region from the upper end to the lower end of the door plate 44. The left and right end portions of each partition plate 49 are alternately spaced from the side member 47, and the injected fluid flows to the left and right to cool the entire door plate 44.
[0046]
  An inlet 51 is provided on one upper side of the door plate 44 (the upper side on the right side in the figure), and a discharge port 52 is provided on the other lower side (the lower side on the left side in the figure).
[0047]
  The injection port 51 is configured by an opening formed upward on the upper side surface of the door plate 44. A cooling water supply pipe 53 is connected to the door frame 42 facing the inlet 51, and an outlet of the cooling water at the tip thereof is provided facing the inlet 51.
[0048]
  In the lower frame portion 42A of the door frame 42, a drainage mass 54 and a drainage pipe 55 connected thereto are provided at a position facing the discharge port 52 below the door plate 44. A handle 56 that is held by hand when the door plate 44 is opened and closed is provided at the center in the vertical direction on the left side of the door plate 44.
[0049]
  In the vicinity of the door 41, a control panel (not shown) for detecting the occurrence of a fire and operating a cooling water supply system is provided.
[0050]
[Operation]
  The door 41 configured as described above operates as follows.
[0051]
  In normal use, the handle 56 is opened by hand, and after passing through, the handle 56 is held and closed.
[0052]
  When a fire occurs, the cooling water supply system is operated by the control panel, and the cooling water is supplied to the door plate 44 via the cooling water supply pipe 53. The cooling water flows out from the tip of the cooling water supply pipe 53, falls to the inlet 51 of the door plate 44, and flows into the door plate 44. Inside the door plate 44, the cooling water flowing in from the inlet 51 flows to the left and right by the plate 49, and contacts the entire inner surface of the surface material 45 and the back material 46 to cool the entire door.
[0053]
  The cooling water that has flowed to the lower portion of the door plate 44 flows out of the discharge port 52 and falls into the drainage mass 54 and is drained to the outside through the drainage pipe 55.
[0054]
  At this time, a sensor for detecting whether or not the door plate 44 is closed may be provided. This is because if the door plate 44 is not closed, the cooling water may spill around.
[0055]
[effect]
  As described above, since the cooling water flow path is formed inside each door 41 to flow the cooling water, the heat can be cut off together with the flame and smoke accompanying the fire as in the first embodiment. it can.
[0056]
  As a result, it is possible to prevent harmful effects caused by radiant heat transmitted to the opposite side of the door plate 44.
[0057]
[Fourth Embodiment]
  Next, a fourth embodiment of the present invention will be described.
[0058]
  This embodiment is an example applied to a sheet that flexibly deforms and partitions a space. Examples of the sheet include one that closes a passage (for example, used in place of the door of FIG. 11), a curtain that closes a window, and a partition that partitions a space. The upper end and lower end of the sheet are fixed in a state where the passage is closed. Specifically, a sheet winding device is provided in an upper portion of a passage or a window, and the sheet is wound on the winding device in a state where the passage or the like is opened. A crossbar made of metal or the like is provided at the lower end portion of the sheet, and the crossbar is locked to the lower end portion of the passage or the window so that the passage or the like is closed with a flexible sheet. .
[0059]
  This sheet is made of silica cloth, glass cloth, carbon fiber, heat-resistant synthetic resin, or the like having excellent fire and heat resistance so that it can flex flexibly. In addition, as a heat resistant synthetic resin, what has heat resistance in synthetic resin itself, or what coated the heat resistant material in synthetic resin may be sufficient.
[0060]
  Two sheets of this fire-resistant and heat-resistant silica cloth or the like are stacked to form a bag, and a fire-resistant, heat-resistant, cooling or heating fluid passage is provided inside to constitute a fire-resistant and heat-resistant sheet. The fluid passage is arranged meandering vertically, horizontally, or annularly so that the fluid can flow throughout the entire interior. Specifically, for example, the same structure as the surface material 45, the back surface material 46, the side surface material 47, and the partition plate 49 of FIGS. 11 and 12 is made of the silica cloth or the like. The fluid passage is waterproofed by applying a waterproof paint or the like.
[0061]
  Further, as in the above embodiments, a cooling water supply system is provided at the upper part of the refractory and heat-resistant sheet, and a discharge system is provided at the lower part.
[0062]
  Also in the case of the fire-resistant and heat-resistant sheet configured as described above, when the occurrence of a fire is detected by the same action as the above-described embodiments, the fluid supply unit is operated to supply the fluid into the fire-resistant and heat-resistant sheet. . The fluid supplied into the fire and heat resistant sheet absorbs heat from the fire and is discharged to the outside, thereby interrupting heat transfer.
[0063]
  Moreover, you may provide one or more outflow holes (hole similar to the cooling water outflow holes 101 and 102 of FIG. 21) for discharging | emitting the cooling water passed through the inside to a fireproof heat-resistant sheet | seat. The diameter of the outflow hole is set larger or smaller.
[0064]
  When the diameter of the outflow hole is reduced, the cooling water will fly to some distance. Thereby, the cooling water which flowed out from the outflow hole extinguishes the surroundings. As a result, the cooling water in the refractory and heat-resistant sheet absorbs heat and discharges it to the outside, and prevents the fire around the refractory and heat-resistant sheet from spreading.
[0065]
  When the diameter of the outflow hole is increased, the cooling water flows along the surface of the refractory and heat-resistant sheet. Thereby, the cooling water which flowed out from the outflow hole wets the surface of the fire and heat resistant sheet. As a result, the cooling water on the surface of the refractory and heat-resistant sheet evaporates and takes heat of vaporization, actively cools the refractory and heat-resistant sheet and blocks heat transfer.
[0066]
  Further, when the fire-resistant and heat-resistant sheet is composed of heat-resistant fibers, the waterproof treatment applied to the fluid passage may be made non-heat-resistant or may not be subjected to the waterproof treatment. As a result, if the cooling water is passed through the fluid passage while the fireproof and heat-resistant sheet is heated by a fire, the waterproof function is deteriorated by heat, or the waterproof treatment is not performed. Water oozes from the gaps between the fibers to the surface of the refractory and heat-resistant sheet. The cooling water that has oozed out on the surface of the refractory and heat-resistant sheet wets the entire surface and evaporates with heat, deprives the heat of vaporization and blocks heat transfer.
[0067]
  As a result, it is possible to prevent harmful effects caused by radiant heat transmitted to the opposite side of the fire and heat resistant sheet.
[0068]
[First Modification]
  In each of the above embodiments, the panel shutter 1 or the like is used as a plate-like member that partitions the space. However, as shown in FIG. 13, a shutter curtain 62 in which a large number of slats 61 are combined may be used. In this case, one slat 61 serves as one passage. Each slat 61 is connected by a water conduit 63 that allows cooling water to flow from the upper slat 61 to the lower slat 61. The water guide pipes 63 are alternately connected to the left and right of the slats 61. Specifically, when the uppermost slat 61 and the lower second slat 61 are connected to each other by a water conduit 63 on one side, the second slat 61 and the next third slat 61 are: The other side is connected by the water conduit 63. This is repeated, and the respective slats 61 are connected alternately by the water guide pipes 63 on the left and right sides, and the cooling water cools the entire shutter curtain 62 while flowing in the respective slats 61 left and right.
[0069]
  As described above, the interior of each slat 61 is used as a flow path for flowing cooling water, and the entire shutter curtain 62 is cooled with cooling water. With the smoke, it will be possible to cut off the heat.
[0070]
[Second Modification]
  In the first modified example, each slat 61 is connected by the water guide pipe 63 at the side end portion thereof, but is not limited to the end portion, and is connected by the water guide pipe 63 on the front side or the back side in the middle of each slat 61. It may be.
[0071]
[Third Modification]
  In the first modified example, the flow paths of the respective slats 61 are connected by the water guide pipe 63, but the cooling water flow paths may be connected by a connection portion between the slats 61. The engaging portion 65 of the slat 61 is configured as shown in FIG. A hook-like fitting claw 66 is formed at the upper end of the slat 61. A fitting claw 67 into which the fitting claw 66 is fitted is formed at the lower end of the slat 61.
[0072]
  The fitting claw 66 is formed by bringing the front surface material 68 and the back surface material 69 into contact with each other at the upper end portion of the slat 61 and bending it into a left-handed hook shape. The upper side surface 61A of the slat 61 is formed to be recessed in a curved shape. An inlet 71 is provided at the bottom of the upper side surface 61A.

The inlet 71 and the outlet 72 are appropriately formed in various shapes such as a round hole and a long hole.
[0074]
  Also by this, the same operation and effect as the first embodiment can be obtained.
[0075]
[Fourth Modification]
  In the second embodiment, the discharge port 33 of the upper panel 30 is simply inserted into the injection port 32 of the lower panel 30 as means for connecting the cooling water flow paths of the upper and lower panels 30. An on-off valve may be provided between them. In this case, as shown in FIGS. 15 and 16, an opening / closing valve 76 is provided in the tube of the discharge port 75, and a valve opening mechanism 78 is provided in the injection port 77 into which the discharge port 75 is inserted. The on-off valve 76 opens inward (upper) and is closed by the weight of the water stored in the panel 79 to prevent the outflow of water and an end portion of the valve plate 81. The hinge rod 82 is movably supported. The valve opening mechanism 78 includes a valve opening rod 84 provided in the pipe of the inlet 77 and a cross-shaped valve opening rod support portion 85 that supports the valve opening rod 84 and allows the flow of cooling water. ing.
[0076]
  In the discharge port 75 and the injection port 77 configured as described above, when the panels 79 guided by the guide rail 3 are stacked, as shown in FIG. Inserted into the inlet 77. As a result, the valve plate 81 of the opening / closing valve 76 of the discharge port 75 is pushed up and opened by the valve opening rod 84 of the valve opening mechanism 78, and the cooling water flow path is connected between the upper and lower panels 79.

  There are cases where the water is stored in advance in the panel 2 and empty. When water is stored in the panel 2, the on-off valve 76 is opened so that the cooling water in the panel 79 flows out from the discharge port 75 and enters the lower panel 79 through the injection port 77. Injected.
[0078]
  When the panel 79 is pulled up, the discharge port 75 comes out of the injection port 77, and the valve opening rod 84 that pushes and supports the valve plate 81 comes out. As a result, the on-off valve 76 is closed and the cooling water is stored in the panel 79.
[0079]
  As a result, the cooling water can be always stored in each panel 79, which is effective against a fire that spreads rapidly.
[0080]
[Fifth Modification]
  In the first and second embodiments, as shown in FIGS. 18 to 20, an opening valve 91 that opens when the panel 79 is grounded to the floor may be provided on the lowest panel 79. The release valve 91 is composed of a discharge pipe 92 that protrudes laterally from the side wall of the panel 79, a closing plug 93 attached to the tip of the discharge pipe 92, and a bottle opener bar 94 provided on the floor side. ing.
[0081]
  A cooling water flow path 95 extending to the tip end portion is formed inside the discharge pipe 92. A support portion 96 that supports the closing plug 93 is formed at the distal end portion of the discharge pipe 92. The support portion 96 supports the closing plug 93 at the tip of the discharge pipe 92, and the closing plug 93 is supported by the support portion 96 so as to close the opening of the cooling water flow path 95. The support portion 96 includes two support claws 97 that extend in a plate shape from both sides at the distal end portion of the discharge pipe 92 and sandwich the blocking plug 93 from both sides. The front ends of the support claws 97 are bent inward and supported so as to hold the closing plug 93 so as to block the front end opening of the cooling water flow path 95. Accordingly, the closing plug 93 is supported only from the left and right by the support claws 97 of the support portion 96 and can be easily removed in the vertical direction.
[0082]
  The closing plug 93 is formed of an elastic member such as rubber and is formed slightly larger than the size of the support portion 96.
[0083]
  The base end portion of the bottle opener rod 94 is embedded in the floor portion, and the rod portion extends upward. The plug opener 94 is embedded so that the bar is positioned directly below the closing plug 93 supported by the support claw 97 in a state where the panel 79 is in contact with the floor.
[0084]
  A drainage mass (not shown) is provided at a position where the bottle opener rod 94 is embedded, and the cooling water flowing out from the panel 79 is received and discharged to the outside.
[0085]
  With the above configuration, when the panel 79 is grounded to the floor, the closing plug 93 supported by the discharge pipe 92 comes into contact with the bottle opener bar 94, and the discharge pipe 92 is pushed downward in this state. As a result, as shown in FIG. 20, the closing plug 93 is pushed up from the lower side by the bottle opening rod 94 and falls off, and the fluid flows out to the inside.
[0086]
[Sixth Modification]
  In the first modification, the closed cooling water flow path is formed in the slat 61 of the shutter curtain 62, but the cooling water outflow holes 101 and 102 may be provided in the slat 100 as shown in FIG. The cooling water outflow hole 101 is configured such that the diameter of the hole is reduced so that the cooling water can fly to some distance. Thereby, the cooling water which flowed out from the cooling water outflow hole 101 extinguishes the circumference | surroundings. As a result, the cooling water in the slat 100 absorbs heat and discharges it to the outside, and prevents the fire around the shutter curtain 62 from spreading.
[0087]
  The cooling water outflow hole 102 has a large diameter so that the cooling water flows along the surface of the slat 100. Thereby, the cooling water flowing out from the cooling water outflow hole 102 wets the surface of the slat 100. As a result, the cooling water of the slats 100 evaporates and takes heat of vaporization, actively cools the slats 100 and blocks heat transfer.
[0088]
[Seventh Modification]
  As shown in FIGS. 22 and 23, a water retaining portion 106 may be provided on the slat 105 of the shutter curtain. The water retention unit 106 includes a water retention plate material 107, support claws 108, and a cooling water supply hole 109.

  The water retention plate 107 is a holding member that holds cooling water as a cooling fluid. Similar to the slat 105, the water retaining plate 107 is formed in an elongated plate shape and is attached so as to cover the entire surface of the slat 105. As the water retaining plate material 107, a polymer polymer excellent in water absorption, cotton, ceramic wool, rock wool, or the like is used. It is desirable to use a material that has excellent water absorption and heat resistance.
[0090]
  The support claw 108 is formed on the surface of the slat 105 over its entire length. The support claw 108 is formed in a C-shaped cross section, and supports the water retaining plate 107 from the top and the bottom along its entire length. A synthetic resin film (not shown) that covers the entire surface is provided on the surface of the water retaining plate 107 supported by the support claws 108 so that the cooling water does not evaporate. This synthetic resin film is easily melted by heat from a fire so that the surface of the water retaining plate 107 is reliably exposed.
[0091]
  The cooling water supply holes 109 are holes for supplying the cooling water flowing in the slats 105 to the water retaining plate 107, and are provided on the surface of the slats 105 (the surface on the support claw 108 side) over the entire area. ing.
[0092]
  The water retaining plate 107 may be provided not only on one side surface of the slat 105 but also on the other side surface or both side surfaces. The water retaining plate 107 may be used not only for the shutter curtain slat 105 but also for other panel shutters.
[0093]
  With the above configuration, the cooling water supplied into the slat 105 flows out from the cooling water supply hole 109 and is sucked into the water retention plate 107. Thereby, the water retention board | plate material 107 is maintained in the state wet with cooling water.
[0094]
  When a fire occurs in this state and the slat 105 is exposed to flame, the water retaining plate 107 occupying the entire surface of the slat 105 is heated. The heated cooling water evaporates and takes heat of vaporization. Thereby, the slat 105 is not heated so much and the heat transfer is interrupted.
[0095]
