(Basic effect)
The present invention relates to a fire hydrant device in a tunnel that draws out a hose with a nozzle housed in a housing opened on the front surface and discharges the water. In the fire hydrant device in a tunnel, a sheet-like member is developed in the opening of the housing to close the opening. In addition, since the seat opening / closing structure that opens the opening is provided by moving the sheet-like member to one end of the opening, the opened sheet-like member does not jump out of the housing opening and does not block the passage. Therefore, it does not hinder evacuation, and the work for storing the drained hose after water discharge and the maintenance work are easy, and the structure is simpler and lighter than the conventional fire hydrant door, so it is inexpensive. Can be.

(Effect of seat opening / closing structure combined with maintenance door)
In addition, the fire hydrant device in the tunnel has a seat opening / closing structure in the lower opening, which is the lower side of the casing opening, when a maintenance door that opens upward with the upper side as an axis is provided in the upper opening, which is the upper side of the casing opening. Therefore, it is only necessary to change the portion of the fire hydrant door provided in combination with the conventional maintenance door to the seat opening / closing structure, which facilitates the realization of the fire hydrant device provided with the seat opening / closing structure.

(Effect of seat opening / closing structure of fire extinguisher storage)
A sheet that covers and closes the opening by opening the sheet-like member to the opening of the housing corresponding to the fire extinguisher housing portion that houses the fire extinguisher, and opens the opening by moving the sheet-like member to one end of the opening Since the opening / closing structure is provided, the opened sheet-like member does not jump out of the housing opening, does not block the passage, and does not hinder evacuation, and the fire extinguisher can be easily taken out. The structure is simpler and lighter than the conventional fire extinguisher door, so that the cost can be reduced.

(Effects of sheet roll device)
Further, the sheet opening / closing structure closes the opening by unwinding the sheet and holding the unwinding end, and rolls the sheet by releasing the holding of the unwinding end to open the opening. Since it is provided at the opening end, it is possible to appropriately unwind and entrain the sheet by using a sheet roll device similar to the curtain roll device.

(Effects of sheet folding device)
The seat opening / closing structure also fixes one end of the sheet to one end of the opening and closes the opening by detachably holding the other end of the sheet to the other end of the opening, and releases the sheet by holding the other end of the sheet. Since the opening is opened by moving one end of the opening to the side and folding it outward, the opened and folded sheet jumps out to the outside, but the amount of popping out is very small compared to the conventional fire hydrant door. Yes, it does not obstruct the passage because it hardly blocks the passage, and the work for storing the hose drained after water discharge and maintenance work are easier, and the structure is simpler and lighter than conventional fire hydrant doors. Thus, the cost can be reduced.

(Effects of shutter device)
In addition, the seat opening / closing structure closes the opening by pulling out the shutter door and holding the drawer end, and the shutter device that stores the shutter door and opens the opening by releasing the holding of the drawer end is one opening end of the opening Therefore, it can be opened and closed without jumping out from the housing opening.

(Effects of remote opening mechanism)
In addition, the open / close structure includes an operation unit that performs an operation of opening the sheet-like member, an opening drive unit that is operated by an open control signal from the outside, and an opening operation of the operation unit or an operation of the opening drive unit. With a remote release mechanism that releases and releases the closed hold, for example, with a nozzle that automatically opens the sheet-like member by an open control signal from a monitoring center based on fire detection, etc., and accommodates it in the housing Fire extinguishing work with a hose is possible, and the user can take out the hose with a nozzle and perform the fire extinguishing work without being confused by the opening operation of the hydrant door.

(Effect of fire hydrant door structure using sheet-like member)
Further, the seat opening / closing structure covers and closes the opening by unfolding and holding the sheet-like member in a state of being positioned inside the opening frame provided in the opening, and releases the holding of the sheet-like member. The opening of the sheet-like member is provided with a fire hydrant door, and the casing is arranged with a partition plate in the lower lateral direction so as to form a storage portion for storing the sheet-like member on the lower side, so that the sheet-like member is opened. In this case, since the sheet-like member is housed inside the opening and the sheet-like member does not pop out to the outside, a fire extinguishing operation such as a hose pull-out performed with the sheet-like member opened is performed by the storage portion of the sheet-like member. It can be done easily without being interrupted.

  In addition, the housing includes a hose with a nozzle and a fire hydrant valve installed in the fire hydrant device by forming a storage part that stores a sheet-like member on the lower side by arranging a partition plate in the lower lateral direction. The open sheet-like member can be accommodated in the housing without being influenced by the installation of the kind, so that the outward protrusion can be eliminated.

(Effect of split structure of housing and fire hydrant door)
In addition, the fire hydrant door is divided into the housing, and the fire hydrant door is detachably provided at the opening of the housing. Therefore, the housing and the fire hydrant door are separately manufactured at the assembly manufacturing stage. By assembling and fixing the fire hydrant door to the opening, the fire hydrant device can be completed, manufacturing and assembly are easy, productivity is high, and manufacturing cost can be reduced.

  In addition, when the sheet-like member is soiled or damaged after installation, the soiled or damaged door is removed from the housing and replaced with a separately prepared door, thereby enabling easy and easy repair.

(Effects of fire hydrant door structure)
In addition, the fire hydrant door is disposed on the back of the sheet-like member, the door frame attached and fixed to the opening of the housing, the upper and lower ends of the back surface of the sheet-like member, a plurality of guide bar members arranged at a predetermined interval therebetween. The guide bar is placed between the plurality of weight bar members arranged between the guide bar members and the opening frames on both the left and right sides of the door frame, and the left and right sides of the sheet-like member are positioned inside the opening frames. A first guide rail that slides the left and right ends of the member in contact with the guide groove and moves in the vertical direction is disposed inside the first guide rail and slidably contacts both ends of the weight bar to restrict movement in the depth direction. By holding the second guide rail that is guided and moved in the vertical direction and the guide bar member at the upper end of the sheet-like member, the sheet-like member is held in a closed state, and the upper end guide bar portion is operated by a predetermined operation. The first guide rail is released by releasing the holding of the guide bar member at the upper end of the sheet-like member in the unfolded state of the sheet-like member. When the guide bar member is dropped along, the both ends of the sheet-like member are located inside the opening frame, so the guide bar member falls while curving the sheet-like member portion in between. As a result, the sheet-like member is folded open inside the lower part of the opening, and the folded part does not jump out at all. Therefore, the fire extinguishing operation such as pulling out the hose and the inspection work are hindered by the folded part of the sheet-like member. It can be easily performed without being done.

  Further, when the holding of the sheet-like member is released and the guide bar member is dropped along the first guide rail, the inward bending of the sheet-like member portion during the fall of the guide bar member is caused by the guide bar member. Energizing is performed with the weight of the weight bar provided between them, and as the guide bar member drops, it is possible to smoothly fold the sheet-like member portion in between.

  In addition, the weight bar member is arranged between the plurality of guide bar members arranged on the back surface of the sheet-like member, and is applied by being applied to the second guide rail so as to restrict the movement in the depth direction of both ends of the weight bar member. By applying tension (weight) to the sheet-like member opened in the state by the weight of the weight bar member, and regulating the movement of the weight bar in the depth direction, the flatness of the sheet-like member in the unfolded state is improved, This makes it possible to produce a texture equivalent to that of a metal fire hydrant door that opens sideways.

(Effect of opening / closing mechanism)
In addition, the opening / closing mechanism provided on the fire hydrant door is provided with a buckle bracket upward on the guide bar member at the upper end of the sheet-like member, a buckle device at the upper opening frame of the door frame, and a buckle bracket inserted into the buckle device. By holding, the sheet-like member is held in the expanded closed state, and the buckle device is released by holding the buckle device by a predetermined operation so that the sheet-like member is folded and opened. By pulling the lever forward, the holding of the buckle fitting is released and the unfolded sheet-like member is dropped to open the sheet-like member easily and reliably for fire extinguishing activities and inspection work.

(Effect due to the distance between the guide bar and weight bar)
Further, in the fire hydrant door, the weight bar member is disposed adjacent to the lower side thereof with respect to the interval (L1) between the weight bar member disposed on the back surface of the sheet-like member and the guide bar disposed adjacent to the upper side thereof. Since the distance (L2) from the guide bar is shortened (L1> L2), the weight bar member is arranged not at the center of the guide bar member but at a position slightly offset downward, and as the guide bar member falls When the sheet-like member portion in between starts to bend inward, the weight bar member is arranged slightly below the center, and the weight of the sheet-like member is further strongly biased by the weight, and the sheet-like member It is possible to more smoothly perform the convolution.

(Effects of upper and lower guide bars)
In the fire hydrant door, the plurality of guide bar members arranged on the back surface of the sheet-like member are plate-like bar members having a rectangular cross section, and the guide bar members arranged at the upper and lower ends of the plurality of guide bar members are both ends. The guide bar member disposed between the upper and lower ends is stored in the guide groove of the first guide rail so as not to rotate in the guide groove of the first guide rail. Therefore, the guide bar at the lower end rotates inward as the sheet-like member drops, and the sheet-like member can be reliably folded inside the door.

  Also, the guide bar member at the upper end is provided with a buckle fitting that is used to open and close the sheet-like member, but if it falls due to the release of the holding of the sheet-like member and is folded inside the lower part of the opening, the upper end guide bar member The bar member rotates outward to tilt the buckle fitting sideways so that the buckle fitting can be prevented from popping up and obstructing the hose drawer.

(Effect of the end of the weight bar guide rail)
The second guide rail has a predetermined position between the first weight bar member from the bottom and the second guide bar member from the bottom in the state where the sheet-like member is expanded and the door opening is closed. Both ends of the weight bar member that are located at the lower end of the guide rail and are formed integrally with a curved guide rail that is curved inwardly extending from the end of the guide rail and the sheet-like member is unfolded. Since the overhanging pieces that restrict the movement of the weight bar in the depth direction are provided at both inner ends of the door frame, the lower side of the second guide bar that guides the movement of the weight bar in the vertical direction is terminated halfway. Thus, it is possible to smoothly perform the folding of the dropped sheet-like member inside.

  In addition, the weight bar member located below the end of the guide rail is in a free state in a state where the sheet-like member is flattened, but the movement of the weight bar member in the free state is applied to both inner ends of the door frame. By abutting the provided protruding piece, it is possible to improve the flatness of the sheet-like member in the unfolded state.

  Further, when the sheet-like member in a folded state is pulled up inside the lower part of the door opening and deployed in a flat closed state, both sides of the weight bar member provided on the sheet-like member folded inside the lower part of the door opening are The guide member moves along the curved guide rail extending inward from the end of the second guide rail to the second guide rail so that the folded sheet-like member can be smoothly flattened to close the door opening. .

(Effect of fire extinguisher box in tunnel)
The present invention provides a fire extinguisher box in a tunnel in which a fire extinguisher is housed in a housing opened on the front surface. The sheet-like member is expanded in the opening to cover and close the opening, and the sheet-like member is opened. Since the seat opening and closing structure that opens the opening by moving to one end is provided, the opened sheet-like member does not jump out of the housing opening and does not block the passage, so it does not hinder evacuation, Further, the fire extinguisher can be easily taken out, and the structure is simpler and lighter than the conventional fire extinguisher door, so that the cost can be reduced.

On the back surface of the screen 170, guide bars 188 are provided at each of the upper end and the lower end, and two guide bars 188 are arranged at equal intervals therebetween. The guide bar 188 is movable up and down by a guide portion 186 disposed on the back side of the door frame 154.

  Weight bars 190 are arranged on the back surface of the screen 170 between the four guide bars 188, respectively. The weight bar 190 is also movable in the vertical direction by a guide portion 186 disposed on the back side of the door frame 154.

  As shown in FIG. 27B and FIG. 28, a first guide rail 194 and a second guide rail 196 are provided on the guide portion 186 disposed on the back side of the door frame 154. The first guide rail 194 disposed on the front side is a sheath-like member provided with a guide groove in the vertical direction, and both ends of the guide bar 188 provided on the back surface of the screen 170 are fitted into the guide groove to guide in the vertical direction. Moving.

  A second guide rail 196 is disposed behind the first guide rail 194 via a gap that forms a guide groove. A gap that functions as a guide groove is formed in the vertical direction between the first guide rail 194 and the second guide rail 196. A stopper portion 190a formed by bending both ends of the weight bar 190 inward is inserted in the guide groove of the second guide rail 196. The second guide rail 196 guides and moves the weight bar 190 in the vertical direction. In a state where the screen 170 is unfolded and the door opening 156 is closed, it functions as a stopper that restricts the movement of the weight bar 190 in the front and depth directions, and the unfolded screen 170 is kept flat, It has a texture equivalent to a fire hydrant door.

  When the unfolding and holding of the screen 170 is released by operating the buckle device 162 of the screen door 150, the screen 170 falls along the guide portion 186 together with the guide bar 188 and the weight bar 190. As shown in FIG. 170 is folded into the lower inside of the door opening 156 and opens the door opening 156.

  The second guide rail 196 that guides and moves the weight bar 190 provided in the guide portion 186 on the back side of the door opening 156 forms a guide rail end by notching the lower side, and following this guide rail end, A curved guide rail 198 curved inward is formed.

  In addition, projecting pieces 192 are provided obliquely downward on both sides of the door opening 156 on the lower side of the curved guide rail 198. The overhanging piece 192 moves up and down, but does not move in the depth direction, and the weight bar 190 arranged at the bottom of the unfolded screen 170 is positioned away from the guide groove of the second guide rail 196. 27A, the stoppers 190a on both sides of the lowermost weight bar 190 are applied to the overhanging piece 192 to restrict the inward movement as shown in FIG.

The bar 188 is rotated outward by the rotating structure of the bar 188 so that the buckle fitting 200 is tilted sideways so as not to obstruct the hose drawer.

(Screen structure)
FIG. 29 is an explanatory view showing the screen taken out from the back side. As shown in FIG. 29, the screen 170 uses a non-flammable, flame retardant, or fire-resistant sheet, and the color of the surface of the sheet is a predetermined designated color that is the same as that of the door frame 154.

  Guide bars 188 are arranged at equal intervals L between the upper and lower ends of the back surface of the screen 170 by adhesion and the like, and weight bars 190 are also arranged between the guide bars 188 by adhesion and the like.

  The guide bar 188 and the weight bar 190 function as a framework and a weight to stretch the screen 170 in a flat state in an unfolded state so that the screen 170 is not easily wrinkled.

  The guide bar 188 is a plate-like rod-like member that is flattened up and down, and the weight bar 190 is similarly a plate-like rod-like member that is flattened up and down. Further, the guide bar 188 and the weight bar 190 hold the screen 170 in an unfolded state by their own weights, and naturally fall with the opening operation to open the door opening 156 with the screen 170 folded to open a sufficient weight. The metal member can be secured.

  The guide bars 188 arranged at the upper and lower ends support the roller 202 at both ends, and the rollers 202 enter the guide grooves of the first guide rail 194 shown in FIGS. A guide bar 188 is rotatably supported. The guide bar 188 disposed between the upper and lower ends is not provided with a roller at both ends but is directly placed in the guide groove of the first guide rail 194, and the tip is rounded so that it can move smoothly.

Here, the weight bar 190 disposed between the guide bars 188 on the back surface of the screen 170 has a distance L1 between the centers of the guide bars 188 adjacent to the upper side and the center of the guide bar 188 adjacent to the lower side. If the interval is L2,
L1> L2
It arrange | positions so that it may become.

  In other words, the weight bar 190 is not located at the center that is half the arrangement interval of the guide bars 188 but at a position slightly offset from the center.

  In this way, when the weight bar 190 is offset from the center between the guide bars 188 and disposed downward, the weight bar 190 between the guide bars 188 is opened when the screen 170 is moved downward and opened. The inward bending of the provided screen portion is urged by the weight of the weight bar 190, causing the screen portion between the guide bars 188 to be distorted and bent during lowering, or the guide bar 188 is inclined obliquely It is possible to suppress the movement from getting worse.

  A buckle fitting 200 is provided in the approximate center of the guide bar 188 disposed at the upper end of the screen 170, and as shown in FIG. 27A, the buckle fitting 162 provided at the upper part of the door opening 156 is inserted into the buckle fitting 200 and held. Thus, the screen 170 is supported in the unfolded state, and the door opening is closed.

  When opening the screen 170, the lever provided on the buckle device 162 is pulled forward to release the holding of the screen 170 by the buckle fitting 200, and the screen 170 is moved along the guide portion together with the guide bar 188 and the weight bar 190. Then, the dropped screen 170 is opened in a state of being folded inside the lower portion of the door opening 156 (the screen folding storage space 172 of the fire hydrant casing 12a shown in FIG. 24).

(Screen guide structure)
FIG. 30 is an explanatory view partially showing the guide structure at the upper part of the screen door. As shown in FIG. 30, a sheath-like first guide rail 194 having a guide groove 204 opened in the vertical direction is arranged on the back side of the door frame 154 provided on the screen door, and the screen is placed in the guide groove 204. The roller 202 pivotally supported is inserted into both ends of the guide bar 188 disposed on the back of the upper end of 170.

  Following the first guide rail 194, a second guide rail 196 is disposed in the depth direction with a predetermined gap, and the gap with the first guide rail 194 forms a guide groove 206 of the second guide rail 196. ing.

  In the guide groove 206 of the second guide rail 196, stopper portions 190a bent inward at both ends of the weight bar 190 disposed on the back surface of the screen 170 are inserted, and the weight bar 190 is guided and moved in the vertical direction along the guide groove 206. In addition, the movement of the weight bar 190 in the forward and depth directions is restricted when the screen 170 is unfolded, and the screen 170 can be kept flat.

  Further, both ends of the screen 170 moved up and down by the guide bar 188 and the weight bar 190 are located on the back surface of the door frame 154 and do not come out forward. Therefore, when the screen 170 is dropped by operating the buckle device. The screen 170 does not jump out of the door opening 156 and can be reliably folded inside the lower portion of the door opening 156.

  FIG. 31 is an explanatory view partially showing the guide structure at the lower part of the screen door. As shown in FIG. 31, the second guide rail 196 that guides and moves the weight bar 190 is cut out obliquely downward at a position just before reaching the lowest weight bar 190 when the screen 170 is unfolded. A terminal end 208 is formed, and a curved guide rail 198 extends downward and inward following the guide rail end 208.

  Thus, by terminating the lower side of the second guide rail 196 and releasing the restriction in the depth direction of the weight bar 190 on the lower side, the screen 170 that is dropped by the operation of the buckle device is moved to the lower part of the door opening 156. In order to be folded inward, the screen 170 is not disturbed.

  A guide bar 188 provided at the lower end of the screen 170 rotatably supports the roller 202 pivotally supported at both ends in the guide groove 204 of the first guide rail 194. The screen 170 is dropped by operating the buckle device. In this case, the guide bar 188 at the lower end is rotated inward by the roller 202, and the screen 170 is shaken inward by this movement, so that folding of the door opening 156 to the lower inner side can be surely started.

  Further, in the unfolded state of the screen 170, the lowermost weight bar 190 is located on the lower side away from the guide rail end point 208 and is in a free state in which it moves in the depth direction as it is, so the side surface of the door frame 154 An overhang piece 192 is arranged on the inside, and the stopper portion 190a of the weight bar 190 that is free is brought into contact with the overhang piece 192, thereby restricting the movement of the weight bar 190 in the depth direction and maintaining flatness. doing. As the projecting piece 192, a flexible fiber-containing resin sheet that can be bent vertically and does not move laterally is provided.

  Further, the curved guide rail 198 extending from the terminal end of the second guide rail 196 has a lower inner side in the folded state of the screen 170 when the screen 170 which is in a folded state is pulled up and closed inside the lower portion of the door opening 156. The weight bar 190 positioned on the guide rail 198 is guided against the curved guide rail 198, allowing the weight bar 190 to smoothly enter the guide groove 206 of the second guide rail 196 through the guide rail end point 208.

In this state, when the lever of the buckle device 162 is operated to release the holding of the buckle metal fitting 200, as shown in FIG. 32 (B), the remaining guide bars 188 except for the lower end guide bar 188 are attached to the first guide rail 194. Along with this, the weight bar 190 begins to descend at the same time along the guide groove, and the screen 170 begins to descend as a whole.

  At this time, the guide bar 188 at the lower end is stopped without being lowered, so that the portion of the screen 170 between the guide bars 188 begins to bend inward as the adjacent guide bar 188 is lowered. Since the weight bar 190 is disposed in the curved portion of the screen 170 between the guide bars 188, a force to push down the curved portion of the screen 170 is applied by the weight of the weight bar 190, and the screen 170 as a whole descends. wear.

Further, since the lower end guide bar 188 is rotatably supported by the first guide rail 194 by the roller 202, the lower end weight bar 190 rotates so as to fall inward as the screen 170 falls, and thereby the guide bar The portion of the screen 170 between 188 is shaken inward to promote the bending.

Subsequently, as shown in FIG. 32C, when the second guide bar 188 from the bottom hits the lower end guide bar 188 and stops, the second curved portion of the screen 170 is lowered along with the lowering of the upper guide bar 188. Is formed. Similarly, as shown in FIG. 32D, a third curved portion is formed, and finally, as shown in FIG. 32E, the three curved portions overlap to bring the screen 170 into a folded state. The door opening 156 is opened.
