Description

[Technical field]

[0001] The present invention relates to a fire extinguisher stand for installing fire extinguishing devices, such as a fire hydrant device that stores a fire hose inside a housing and a fire extinguisher box that stores a fire extinguisher inside a housing, on the wall surface of a tunnel, and a fire extinguisher equipped with a fire extinguisher stand. [Background technology]

[0002] The fire extinguishing device of the present invention will be described by taking a fire hydrant device as an example. In a fire hydrant device installed in a tunnel or the like, for example as disclosed in Patent Document 1, the housing of the fire hydrant device is installed in a "box cut-out portion formed in the tunnel wall." Fire hydrant devices may be required to be installed at specified distances (e.g., 50 m) within a tunnel, and it is necessary to ensure that each fire hydrant device installed along the tunnel is a specified distance away. In this case, the position where the fire hydrant is to be installed is accurately measured in advance, an anchor is driven into the anchor at that position, and the fire hydrant is then installed on the anchor.

[0003] [Patent Document 1] JP 2015-44039 A Summary of the Invention [Problem to be solved by the invention]

[0004] Recently, large-diameter tunnels are often constructed using the shield method. In this case, the tunnel walls are constructed in segments at the same time as the tunnel is excavated, making it impossible to perform box punching as disclosed in Patent Document 1, and therefore impossible to drive anchors into designated locations.

[0005] Therefore, when installing a fire hydrant device on a tunnel wall having a segment structure, it is possible to use an insert anchor that is already installed in the segment. However, because the insert anchors are installed at the span of the segment, when fire hydrant devices are installed using insert anchors, as described above, it is not possible to set the intervals between each fire hydrant device installed along the tunnel at a specified distance. Therefore, there is a demand for a fire extinguishing device rack that can maintain a constant distance between each fire hydrant device installed along a tunnel, even when insert anchors are used.

[0006] When installing fire hydrant devices on the walls of tunnels that are not shielded, anchors are driven into the tunnel at predetermined positions as mentioned above, but when installing the fire hydrant devices based on the driven anchors, it is necessary to accurately measure the anchor positions in advance. However, when installing fire hydrant devices that are installed every few dozen meters, it is difficult to accurately measure and install the distance between each device and the distance from the road surface. For this reason, there is a demand for a fire extinguishing device stand that allows a fire hydrant device to be installed by adjusting the position from the anchor position after the anchor is installed, even in tunnels other than shield tunnels.

[0007] In addition to fire hydrants, fire extinguisher boxes containing fire extinguishers are sometimes installed on tunnel walls, and the above issues also apply to fire extinguisher boxes.

[0008] Therefore, an object of the present invention is to provide a fire extinguishing device stand that allows a fire extinguishing device such as a fire hydrant device or a fire extinguisher box to be mounted on a tunnel wall surface in such a manner that the position can be adjusted, and a fire extinguishing device equipped with the fire extinguishing device stand. [Means for solving the problem]

[0009] (1) The fire extinguishing device stand according to the present invention is for installing a fire extinguishing device having a fire extinguishing device housed inside a housing on the wall surface of a tunnel, The device is characterized by comprising a fixing member that is fixed to the wall surface of the tunnel, and a mounting and fixing member that is attached to the fixing member directly or via another member and is configured to be adjustable in position laterally relative to the fixing member, on which the housing is mounted and fixed.

[0010] (2) Also, in the item described in (1) above, the mounting and fixing member has a long hole extending laterally, and the fixing member is equipped with a bolt and nut that are inserted into the long hole and fixed in the desired position.

[0011] (3) A fire extinguishing device stand for installing a fire extinguishing device having a fire extinguishing device stored inside a housing on the wall of a tunnel, A fixing member fixed to a wall surface of the tunnel; The apparatus further comprises a mounting and fixing member which is fixed to the fixing member directly or via another member, and on which the housing is mounted and fixed so as to be adjustable in position in the lateral direction.

[0012] (4) In addition, in the device described in any one of (1) to (3) above, the mounting and fixing member is attached to the fixing member so that its position in the vertical direction can be adjusted.

[0013] (5) A fire extinguishing apparatus according to the present invention is characterized by comprising the fire extinguishing apparatus stand described in any one of (1) to (4) above. Effect of the Invention

[0014] The fire extinguishing device according to the present invention includes a fixing member fixed to the wall surface of the tunnel, and a mounting and fixing member attached to the fixing member directly or via another member, configured to be laterally position adjustable relative to the fixing member, and on which the housing is mounted and fixed, so that the fire extinguishing device can be mounted to the tunnel wall surface in a position adjustable manner. As a result, in the case of a shield tunnel, the fire extinguishing device can be mounted to the wall surface of the tunnel using insert anchors so that the distance between each fire extinguishing device installed in the tunnel axial direction is constant. In addition, when the fire extinguishing device is installed by driving an anchor into the tunnel wall surface and using the anchor, even if the anchor position is misaligned, the fire extinguishing device can be installed in the correct position after the anchor is installed, so high installation accuracy of the anchor is not required, and the installation efficiency of the fire extinguishing device is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] [Embodiment 1] In the following description, as an example of a fire extinguisher, a fire hydrant device 3 in which a hose as a fire extinguishing device is stored inside a housing 1 as shown in Fig. 1 will be described, with a description being given of an embodiment in which the position can be adjusted in the vertical and horizontal directions. Note that in the present embodiment 1, the position of the fire hydrant device 3 can also be adjusted in the vertical direction, and the reason for this will first be described below.

[0017] Recently, large-diameter tunnels are often constructed using the shield method. In this case, the tunnel walls are constructed in segments at the same time as the tunnel is excavated, making it impossible to perform box punching as disclosed in Patent Document 1, and therefore impossible to drive anchors into designated locations. Therefore, when installing a fire hydrant device on a tunnel wall having a segment structure, it is possible to use an insert anchor that is already installed in the segment. However, the position of each insert anchor arranged along the tunnel axis direction is generally constructed so that it is at a fixed position relative to the tunnel wall surface, but the position of each insert anchor varies in height from the road surface. This point will be explained based on Figure 14.

[0018] Figure 14 shows cross sections perpendicular to the axial direction of a tunnel, with Figure 14(a) being a cross section at the position of a left curve and Figure 14(b) being a cross section at the position of a right curve. A guard passage 99 is provided on the left side of the roadway surface 98 in the figure. Focusing on the tunnel wall on the left side of the figure, if an insert anchor is provided at a height position 1 / 2 the tunnel radial direction (intersection A of the center line and the wall surface), the absolute position of this position with respect to the entire tunnel wall surface will be a height position 1 / 2 the tunnel radial direction in both cases of Figure 14(a) and Figure 14(b), and both are at the same height position.

[0019] However, in the case of a left curve, as shown in Figure 14(a), the left side of the road surface 98 has a lower slope and the right side has a higher slope, whereas in the case of a right curve, as shown in Figure 14(b), the left side of the road surface 98 has a higher slope and the right side has a lower slope, so the distance from the road surface 98 of the left curve to the position of point A is significantly different from the distance from the road surface 98 of the right curve to the left. This difference depends on the diameter of the tunnel and the steepness of the curve, but can be as large as about 1m. For this reason, even if the fire hydrant devices are fixed to the tunnel wall using insert anchors at the same height, the positions of the fire hydrant devices from the road surface 98 will be different.

[0020] On the other hand, since it is anticipated that a fire hydrant device installed on a tunnel wall will be operated not only from a supervisor's passage 99 but also from the road surface 98, it is required that the operating position be constant from the road surface 98. However, if the fire hydrant device is fixed in that position using an insert anchor, as mentioned above, there is a problem that the operating position will not be in the specified position because the height position of the fire hydrant device from the road surface 98 will differ. Therefore, there is a demand for a fire extinguishing device stand that can maintain a constant operating position from the road surface 98 even when an insert anchor is used. This is the reason why the position of the fire hydrant device 3 is also adjustable in the vertical direction in this embodiment.

[0021] The fire extinguishing apparatus stand 5 in this embodiment is a fire extinguishing apparatus stand 5 for installing a fire hydrant apparatus 3 on a tunnel wall surface 7, and is characterized in that it comprises a lower fixing member 9 as a fixing member fixed to the tunnel wall surface 7, a vertical member 11 attached to the lower fixing member 9 so as to be adjustable in position in the up and down direction, and a mounting and fixing member 13 configured to be adjustable in position in the lateral direction on the lower fixing member 9 via the vertical member 11, and on which the housing 1 of the fire hydrant apparatus 3 is mounted and fixed, as shown in Figures 1 to 3. In addition, since the fire extinguisher stand 5 in this embodiment is used to place and fix the bottom surface of the housing 1 of the fire hydrant device 3, it functions with the above-mentioned configuration. However, in this embodiment, in order to fix the fire hydrant device 3 more stably, it is provided with a rear fixing member 15 that fixes the rear side of the fire hydrant device 3 to the wall surface 7 of the tunnel to maintain the posture of the fire hydrant device 3. Each component will be described in detail below.

[0022] <Fire hydrant equipment> The fire hydrant device 3 accommodates a fire hose inside the housing 1. The fire hydrant device 3 also includes a device that accommodates a fire extinguisher in addition to the fire hose. The housing 1 is made of a steel plate and has a rectangular box shape, and has a bottom surface provided with bolt insertion holes (not shown) for bolting to a mounting and fixing member 13 constituting one component of the fire extinguisher stand 5. In addition, an opening / closing door (not shown) is provided on the front panel of the housing 1, and when the fire hydrant device 3 is to be used, the opening / closing door is opened.

[0023] Furthermore, as shown in FIG. 2, the rear surface of the housing 1 below a predetermined height forms an inclined surface portion 17 that slopes downward and from the rear surface side to the front surface side. By providing an inclined surface portion 17 on the rear side of the housing 1, interference with the tunnel wall surface 7 of the shield tunnel can be avoided when installing the fire hydrant device 3 on the tunnel wall surface 7, and the protrusion of the fire hydrant device 3 from the tunnel wall surface 7 can be minimized.

[0024] <Lower fixing member> The lower fixing member 9 corresponds to the fixing member of the present invention, and is a member fixed to the insert anchor 19 of the wall surface 7. As shown in FIG. 4, the lower fixing member 9 comprises a rectangular back plate 21, a connecting member 25 whose rear end is joined to the back plate 21 and whose front end is joined to an engaging member 23, and the engaging member 23 fixed to the front end of the connecting member 25.

[0025] A bolt hole 27 into which a bolt is inserted is provided in the approximate center of the back plate 21. The back plate is fixed to the wall surface 7 by inserting a bolt into the bolt hole 27 and screwing the bolt into the insert anchor 19.

[0026] The connecting member 25 is made of a member with a U-shaped cross section, and is set so that its rear end face and front end face form a predetermined angle θ (see FIG. 4(a)). This θ approximately matches the inclination angle of the tunnel wall surface 7 at the position of the insert anchor 19. By setting the rear end face and front end face of the connecting member 25 at the predetermined angle θ, when the back plate 21 is fixed to the rear end of the connecting member 25 and disposed along the tunnel wall surface 7, the front end face of the connecting member 25 becomes an approximately vertical surface, and the engaging member 23 can be attached to the front end face of the connecting member 25 in the vertical direction. The engaging member 23 has a U-shaped horizontal cross section, and two positioning bolt holes 31 are provided at the top and bottom of opposing pieces 29 of the U. As described above, when the back plate 21 is attached along the slope of the tunnel wall surface 7, the engaging member 23 becomes approximately vertical.

[0027] <Vertical member> As shown in FIG. 5, the vertical member 11 is a vertically elongated member having a U-shaped cross section similar to the engaging member 23, and has, for example, eight bolt holes 35 formed in a pair of opposing pieces 33. A tubular protrusion 39 is provided on the front side of the upper end of the front portion 37 connecting the pair of pieces 33, and abuts against the back surface of the bent front piece 43 of the mounting and fixing member 13. A nut 41 is provided on the back surface side of the front portion 37 on which the tubular protrusion 39 is provided.

[0028] As shown in Fig. 6, the opposing pieces 33 of the vertical member 11 are inserted between the opposing pieces 29 of the engaging member 23 of the lower fixing member 9, and the two are fitted together. Then, the bolt hole 31 of the engaging member 23 is aligned with the bolt hole 35 of the vertical member 11, and a positioning bolt is inserted, thereby fixing the position of the vertical member 11. In FIG. 6, the position of the dashed line is the position of the insert anchor 19 that fixes the back plate 21, and the lower fixing member 9 is fixed to this position. The position of the vertical member 11 moves upward in the order of FIG. 6(a) to FIG. 6(c). In other words, the bolt hole 35 of the vertical member 11 fixed to the lower fixing member 9 is changed from the upper side to the lower side, and a positioning bolt is inserted. In this way, by adjusting the vertical position of the vertical member 11 relative to the lower fixing member 9, it is possible to adjust the vertical position of the mounting and fixing member 13 provided at the upper end of the vertical member 11. By adjusting the vertical position of the mounting and fixing member 13, it is possible to adjust the vertical position of the fire hydrant device 3 mounted and fixed on the mounting and fixing member 13.

[0029] <Mounting and fixing parts> The mounting and fixing member 13 is a member on which the housing 1 of the fire hydrant device 3 is placed and fixed. The mounting and fixing member 13 is a member having a substantially U-shaped cross section perpendicular to the axis, with the same length as the width of the housing 1 of the fire hydrant device 3. As shown in FIG. 6, the mounting and fixing member 13 is installed on the upper end of the vertical member 11 with the opening side of the U-shape facing down. The surface portion connecting the opposing pieces 43 of the U-shape is the mounting and fixing surface portion 45 on which the housing 1 is placed and fixed. At both ends of the mounting and fixing surface portion 45, bolt holes 47 are provided through which bolts for connecting to the housing 1 are inserted. At both ends of the mounting and fixing surface portion 45, rectangular openings 49 are provided, through which wiring, cables, connection hoses, etc. can be inserted (see FIG. 7).

[0030] A slit 51 is formed over almost the entire length in the front piece 43 of the mounting and fixing member 13. The slit 51 is for fixing the mounting and fixing member 13 to the vertical member 11, and as shown in Fig. 6, the tubular protrusion 39 of the vertical member 11 is positioned on the back side of the slit 51, and in this state, a bolt is inserted and screwed into the nut 41 of the vertical member 11 and tightened, thereby fixing the mounting and fixing member 13 at a desired position relative to the vertical member 11. That is, by providing the slit 51 in the front piece 43 of the mounting and fixing member 13 and making it possible to fix the slit 51 and the vertical member 11 at a desired position, the position of the fire hydrant device 3 in the lateral direction (left and right direction) can be adjusted.

[0031] <Rear fixing part> The rear fixing member 15 consists of a wall-side fixing member 53 that is fixed to an insert anchor 19 on the wall surface 7 of the tunnel, and a housing-side fixing member 55 that is attached to a desired position on the rear side of the housing 1 of the fire hydrant device 3 and is connected and fixed to the wall-side fixing member 53.

[0032] <Wall side fixing member> As shown in Figure 8, wall-side fixing member 53 has a fixing surface portion 57 fixed to insert anchor 19, a wall-side connecting surface portion 59 bent forward at approximately a right angle to fixing surface portion 57 and connected to housing-side fixing member 55, and a stiffening surface portion 61 provided across both sides of the L-shaped portion consisting of the side end portion of wall-side connecting surface portion 59 and the side end portion of fixing surface portion 57, to stiffen fixing surface portion 57 and wall-side connecting surface portion 59.

[0033] The fixing surface portion 57 is provided with a bolt hole 63 through which a bolt to be fixed to the insert anchor 19 is inserted. As shown in Figures 8(c) and 8(d), this bolt hole 63 is an elongated hole that is long in the vertical direction, allowing adjustment for vertical positional deviation. A bolt hole 65 is provided in the center of the wall-side connecting surface portion 59, and a nut 67 is fixed to the underside of the wall-side connecting surface portion 59 at the position where the bolt hole 65 is provided.

[0034] <Housing side fixing member> The housing side fixing member 55 is made of an angle material having an L-shaped cross section perpendicular to the axis, and has a housing side fixing surface portion 69 which is bolted to the rear surface of the housing 1, and a housing side connecting surface portion 71 which is placed on and fixed to the wall side connecting surface portion 59 of the wall side fixing member 53. The housing-side fixing surface portion 69 has bolt holes 73 at both ends, and nuts 75 fixed to the locations where the bolt holes 73 are provided. In addition, a slit 77 is formed over almost the entire length of the housing side connecting surface portion 71, and by inserting a bolt into the slit 77 and bolting it to the wall side connecting surface portion 59, it is possible to adjust the lateral position relative to the wall side fixing member 53 and fix it.

[0035] In addition, a plurality of bolt insertion holes (not shown) are formed in the height direction on the rear surface of the housing 1 corresponding to the adjusted height of the vertical member 11, and the housing side fixing member 55 is fixed in advance to the rear surface of the housing 1 corresponding to the height position of the vertical member 11.

[0036] A method for mounting the fire hydrant device 3 on the wall surface 7 of a tunnel using the fire extinguisher stand 5 of this embodiment configured as described above will be described.

[0037] First, the lower fixing member 9 is bolted to the tunnel wall surface 7. Specifically, the bolt holes 27 of the back plate 21 in the lower fixing member 9 are aligned with the positions of the insert anchors 19, and the bolts are screwed in to fix the back plate 21 to the tunnel wall surface 7. In this embodiment, as shown in Figs. 1 and 3, two lower fixing members 9 are used to install one fire hydrant device 3, so the two lower fixing members 9 are fixed.

[0038] Next, the vertical members 11 are attached to the lower fixing members 9 with their heights adjusted to a predetermined height. The height is adjusted by selecting the most appropriate bolt hole 35 from among a plurality of bolt holes 35 provided in the vertical member 11. The specified height to which the vertical member 11 is adjusted is a height at which, when the fire hydrant device 3 is installed, the position of the operating part of the fire hydrant device 3 is a predetermined height above the road surface.

[0039] Next, the mounting and fixing member 13 is placed on the upper end surface of the vertical member 11, and the left-right position of the mounting and fixing member 13 is adjusted to a predetermined position. With the mounting and fixing member 13 placed on the upper end surface of the vertical member 11, the tubular protrusion 39 provided on the upper end of the vertical member 11 is positioned on the back side of the slit 51, as shown in FIG. As mentioned above, the fire hydrant devices 3 need to be installed at a specified interval in the tunnel axis direction, and the left-right position adjustment of the mounting and fixing member 13 is performed so that the distance between each fire hydrant device becomes a specified distance.

[0040] Once the left and right positions of the mounting and fixing member 13 have been determined, a bolt is inserted into the slit 51 of the mounting and fixing member 13, passed through the tubular protrusion 39 of the vertical member 11, and screwed into the nut 41 to fix it. At this time, the tubular protrusion 39 supports the back side of the slit 51 of the mounting and fixing member 13, so that deformation of the front piece 43 of the mounting and fixing member 13 can be prevented even when the bolt is screwed in.

[0041] Next, the wall surface side fixing member 53 of the rear surface fixing member 15 is fixed to the insert anchor 19 above the insert anchor 19 to which the lower portion side fixing member 9 is attached. The wall surface side fixing member 53 may be attached at the same time as the lower portion side fixing member 9 is attached. Next, the housing-side fixing member 55 is bolted to a predetermined position on the back surface of the housing 1 of the fire hydrant device 3. As described above, the back surface of the housing 1 is provided with a plurality of bolt insertion holes in the height direction, and the bolt insertion hole for attaching the housing-side fixing member 55 is selected so that the height from the bottom surface of the fire hydrant device 3 is approximately the same as the height from the top surface of the mounting and fixing member 13, the height of which has been adjusted, to the wall surface-side fixing member 53.

[0042] Next, the fire hydrant device 3 is placed on the mounting and fixing member 13, and the bottom surface of the fire hydrant device 3 and the mounting and fixing member 13 are fixed with bolts. At this time, since the mounting and fixing member 13 has its position adjusted in the height direction and the left and right direction, by mounting the fire hydrant device 3 so that the position of the bolt insertion hole is aligned with the position of the bolt hole 47 of the mounting and fixing member 13, the position of the fire hydrant device 3 in the up-down direction and the left-right direction relative to the road surface is set to a predetermined position. Furthermore, when the fire hydrant device 3 is placed on the mounting and fixing member 13, the housing-side connecting surface portion 71 of the housing-side fixing member 55 is placed on the wall-side connecting surface portion 59 of the wall-side fixing member 53, and they are joined with bolts. At this time, since the fixing surface portion 57 of the wall-side fixing member 53 is provided with a vertically elongated bolt hole 63, the vertical position of the wall-side fixing member 53 can be finely adjusted.

[0043] As described above, according to the fire extinguisher stand 5 of this embodiment, the fire hydrant device 3 can be installed on the tunnel wall 7 by utilizing the insert anchors 19 provided on the segments of the tunnel wall 7, and further, it is possible to adjust the left-right position of the mounting and fixing member 13 on which the fire hydrant device 3 is mounted and fixed. Therefore, the insert anchors 19, which are not necessarily provided at the installation intervals of the fire hydrant devices 3, can be used to adjust the distance between the fire hydrant devices 3 of a plurality of fire hydrant devices installed in the tunnel axis direction to a predetermined distance. In addition, the position in the height direction can be adjusted, so even if the height or position of the insert anchor 19 from the road surface of the roadway varies, the height from the road surface to the operating part of the fire hydrant device 3 can be kept constant.

[0044] [Embodiment 2] In embodiment 1, an example was shown in which the mounting and fixing member 13 was constructed separately from the vertical member 11 and the position was adjustable between the mounting and fixing member 13 and the vertical member 11. However, in this embodiment, the mounting and fixing member 81 and the vertical member 11 are fixed together and the installation position of the fire hydrant device 3 is adjustable left and right relative to the mounting and fixing member 81. The present embodiment is also capable of adjusting the vertical position, but as the configuration for adjusting the vertical position is the same as in embodiment 1, a description thereof will be omitted. The following describes the mounting and fixing member 81 and the rear fixing member 83 which are related to the left-right position adjustment.

[0045] <Mounting and fixing parts> 10, 12, and 13(a), the mounting and fixing member 81 is a member having a generally U-shaped cross section and is longer than the width dimension of the fire hydrant device 3. The length of the mounting and fixing member 81 is preferably greater than or equal to "the width of the fire hydrant device 3 plus one span of the insert anchor in the left-right direction." The mounting and fixing member 81 has four bolt holes 85 at the front piece of the U-shape for fixing to the vertical member 11. The bolt holes 85 are provided at positions corresponding to the positions of the tubular protrusions 39 of the installed vertical member 11.

[0046] The mounting surface of the mounting and fixing member 81 on which the housing 1 is placed is provided with a rectangular opening 87 that extends over substantially the entire length, and a slit 89 that extends along the rectangular opening 87 over substantially the entire length. The rectangular opening 87 is for inserting wiring, cables, connecting hoses, etc. from the housing 1 of the fire hydrant device 3. The slit 89 is for inserting a bolt for bolting the housing 1 of the fire hydrant device 3. By providing the rectangular opening 87 and the slit 89 over substantially the entire length of the mounting and fixing member 81, the fire hydrant device 3 can be mounted and fixed at a desired position on the mounting and fixing member 81.

[0047] <Rear fixing part> As shown in FIG. 12, the rear fixing member 83 is composed of the wall fixing member 53 described in the first embodiment and a second wall fixing member 84 (see FIG. 13(b)) that is fixed to the wall via the wall fixing member 53. The second wall fixing member 84 is composed of an L-shaped angle material that is set to be longer (the same length as the mounting fixing member 81) than the width dimension of the fire hydrant device 3. The wall fixing piece 91 that is fixed to the wall fixing member 53 in the second wall fixing member 84 has four bolt holes 93. The bolt holes 93 are provided at positions corresponding to the positions of the wall fixing member 53 that is fixed to the insert anchor 19 of the wall 7 of the tunnel. In addition, a slit 97 is formed over almost the entire length of the housing connecting piece 95 that is connected to the L-shaped housing side.

[0048] The method of mounting the fire hydrant device 3 on the tunnel wall surface 7 using the fire extinguisher stand 79 of this embodiment configured as described above will be described below, focusing on the mounting and fixing member 81 and the back fixing member 83.

[0049] The lower fixing member 9 is fixed to the tunnel wall 7 with bolts, and the vertical member 11 is adjusted in height and attached to the lower fixing member 9. This is the same as in the first embodiment.

[0050] Next, the mounting and fixing member 81 is placed on the upper end surface of the vertical member 11, and the tubular projection 39 provided on the upper end of the vertical member 11 is aligned with the position of the bolt hole 85 of the mounting and fixing member 81 and fixed with a bolt.

[0051] Next, the wall side fixing member 53 is fixed to the four insert anchors 19 above the insert anchor 19 to which the lower side fixing member 9 is attached, and further the second wall side fixing member 84 is fixed to the wall side fixing member 53. Note that the wall side fixing member 53 and the second wall side fixing member 84 may be attached simultaneously with the attachment of the lower side fixing member 9.

[0052] Next, the fire hydrant device 3 is placed on the mounting and fixing member 81, and the position of the fire hydrant device 3 in the left-right direction is adjusted. In this case, since the mounting and fixing member 81 has a rectangular opening 87 and a slit 89 formed over almost its entire length, wiring etc. can be inserted and bolted regardless of the position of the fire hydrant device 3 placed on the mounting and fixing member 81.

[0053] Once the left and right position adjustment is complete, a bolt is inserted through the slit 89 of the mounting and fixing member 81 and fixed to the bolt insertion hole provided on the bottom surface of the housing 1 of the fire hydrant device 3, and the bottom surface of the fire hydrant device 3 and the mounting surface of the mounting and fixing member 81 are fixed with the bolt. The bolt insertion hole on the rear side of the housing 1 faces the slit 97 of the second wall side fixing member 84, so that the rear side of the housing 1 and the second wall side fixing member 84 are fixed with the bolt by inserting a bolt through the slit 97. It is necessary to form bolt insertion holes on the back surface of the housing 1, and these bolt insertion holes may be formed in two locations in the width direction (horizontal direction) and in multiple stages in the height direction (vertical direction). These bolt insertion holes may be elongated holes that are long in the vertical direction so that their positions can be adjusted.

[0054] As described above, according to the fire extinguisher stand 79 of this embodiment, as in embodiment 1, the fire hydrant device 3 can be installed on the tunnel wall 7 by utilizing the insert anchor 19 provided on the segment of the tunnel wall 7, and the distance between the fire hydrant devices 3 installed in the tunnel axis direction can be adjusted to a predetermined distance. In addition, the position in the height direction can be adjusted, so even if the height position of the insert anchor 19 from the road surface of the roadway varies, the height from the road surface to the operating part of the fire hydrant device 3 can be kept constant.

[0055] In the above-mentioned first and second embodiments, the mounting and fixing members 13, 81 are installed on the lower fixing member 9 via the vertical member 11, but when vertical position adjustment is not required, the mounting and fixing members 13, 81 may be attached directly to the lower fixing member 9. In this case, in the type of the first embodiment, the mounting and fixing member 13 needs to be able to adjust its position in the left-right direction relative to the lower fixing member 9, and the lower fixing member 9 may be, for example, an integrated lower fixing member 9 and vertical member 11 as shown in the first embodiment. On the other hand, in the type of the second embodiment, it is sufficient to simply fix the mounting and fixing member 81 to the lower fixing member 9.

[0056] In addition, in the above-mentioned embodiments 1 and 2, a plurality of bolt holes 35 are provided in the vertical member 11, and the vertical position of the vertical member 11 relative to the lower fixed member 9 is adjusted in stages by selecting the desired bolt hole 35. However, it is also possible to form a long hole in the vertical direction in the vertical member 11 so that the vertical member 11 can be adjusted steplessly relative to the lower fixed member 9.

[0057] In addition, in the above embodiments 1 and 2, a fire hydrant device 3 that stores a fire hose inside has been used as an example of a fire extinguishing device, but the fire extinguishing device of the present invention also includes a fire extinguisher box that stores only a fire extinguisher. Furthermore, in the above-mentioned first and second embodiments, a plurality of vertical members 11 (two in the first embodiment, and four in the second embodiment) are used to install one fire hydrant device 3, but in the present invention, the number of vertical members 11 used to install one fire hydrant device 3 is not particularly limited. In particular, in the case of a fire extinguisher box, since the width is short, one fire extinguisher box can be installed using one vertical member 11. Furthermore, by configuring the vertical member 11 from a T-shaped member having horizontal pieces extending in the left-right direction from its upper end, more stable support can be achieved even if the number of vertical members 11 is small.

[0058] In addition, in the above-mentioned first and second embodiments, an example is shown in which the rear fixing members 15, 83 are provided to fix the rear of the housing 1 of the fire hydrant device 3 to the wall surface 7 in order to maintain the posture of the fire hydrant device 3, but the member for fixing the rear of the fire hydrant device 3 is not limited to the above example because it is an auxiliary member for maintaining the posture of the fire hydrant device 3, and does not support the load of the fire hydrant device 3. As long as it is a member that connects any part of the housing 1 to the wall surface 7 of the tunnel, its shape does not matter. As in the above-mentioned first and second embodiments, it is preferable to provide a member for fixing the rear of the fire hydrant device 3, but there is no problem even if the rear fixing members 15, 83 of the fire hydrant device 3 are not provided, for example, if the rear of the housing of the fire hydrant device 3 is abutted against the wall surface 7 of the tunnel to support the load on the wall surface 7 of the tunnel.

[0059] In the above explanation, the fire extinguisher racks 5, 79 for mounting the fire hydrant device 3 on the wall 7 are described on the assumption that the fire hydrant device 3 can be mounted on places other than the tunnel wall 7. However, if it is assumed that the fire hydrant device 3 will be mounted on the tunnel wall 7, the fire extinguisher racks 5, 79 described in the first and second embodiments can also be considered as a fire hydrant device to be mounted on the tunnel wall.
