Description

[Technical Field]

[0001] The present invention relates to a gas valve mounting device for mounting a gas valve to a plate-like interior material that separates the interior from the outside and has a through-hole formed therein. [Background technology]

[0002] When attaching a gas valve to a wall panel, which is a plate-like interior material that separates the inside and outside of a room, there are two ways to do it: the gas valve is temporarily attached to a stud or the like on the outside of the wall panel before the wall panel is installed (pre-installation), or the installation of the gas valve begins after the wall panel is installed (post-installation).

[0003] As an example of a pre-attached installation, a gas valve mounting device 80 disclosed in Patent Document 1 below will be described with reference to Figures 21 and 22. The gas valve mounting device 80 is used to mount a gas valve 80a on a wall plate 90 having a through-hole 90a formed therein, and includes a bracket (first metal fitting) 81 arranged on the back side of the wall plate 90, a plate-shaped fixing frame (second metal fitting) 82 arranged on the front side of the wall plate 90 and having a window hole 82a facing the through-hole 90a of the wall plate 90 and connected to the bracket 81 via the through-hole 90a, and a holder 83 arranged on the back side of the wall plate 90 and connected to the fixing frame 82 via the through-hole 90a and to which the gas valve 80a is attached.

[0004] The bracket 81 has a frame plate portion 81b in which a window hole 81a that faces the through hole 90a of the wall plate 90 is formed, an attachment plate portion 81c that extends perpendicularly from one side edge of the frame plate portion 81b toward the outside of the wall plate 90 and is attached to a stud 91 (support material) on the back side of the wall plate 90, and a support plate portion 81d that extends from the inner periphery of the window hole 81a of the frame plate portion 81b toward the outside of the wall plate 90 and supports the holder 83 so that it can move in and out of the wall plate 90.

[0005] To mount a gas valve 80a on a wallboard 90 using the gas valve mounting device 80, first, before constructing the wallboard 90, the mounting plate portion 81c of the bracket 81 is aligned with and mounted against a stud 91 on the back side of the wallboard 90. Next, the gas valve 80a is mounted to a holder 83 via a mounting fixture 80b (FIG. 22) provided on the gas valve 80a, and the holder 83 is supported by the support plate portion 81d of the bracket 81 so that it can move in the indoor and outdoor directions. The holder 83 is then moved to a position in the outdoor direction, thereby temporarily mounting the gas valve 80a.

[0006] Next, the wall panel 90 is installed, and a through-hole 90a is formed by cutting the wall panel 90 from the inside of the room along the window hole 81a in the frame plate portion 81b of the bracket 81. The holder 83 is moved from this through-hole 90a toward the inside of the room along the support plate portion 81d of the bracket 81, thereby pulling the gas valve 80a to a predetermined position.

[0007] Then, after the operation unit 84 is placed in the through-hole 90a so as to surround the plug portion of the gas cock 80a, the fixing frame 82 is placed on the front side of the wall panel 90 and positioned accordingly. Mounting screws 85 are inserted into the two insertion holes located diagonally outside the window hole 82a of the fixing frame 82, and then passed through the operation unit 84 and screwed into the installation fixture 80b (Figure 22). This connects and fixes the fixing frame 82 and holder 83.

[0008] Additionally, mounting screws 86 are inserted into two elongated holes above and below the window hole 82a of the fixed frame 82 and screwed into the frame plate portion 81b of the bracket 81. This connects and fixes the fixed frame 82 and bracket 81, and the fixed frame 82 is pressed against the wall plate 90. In this way, the gas valve 80a is attached to the wall plate 90. Thereafter, a plate frame 87 is attached so as to surround the fixed frame 82, and a decorative plate 88 is attached so as to overlap the plate frame 87, completing the installation of the gas valve.

[0009] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-189121 Summary of the Invention [Problem to be solved by the invention]

[0010] When installing a gas valve using the gas valve installation device 80, the fixing frame 82 attached to the wall panel 90 is fixed to the installation fixture 80b with the installation screws 85, and is thereby fixed to the holder 83, but the diameter of the insertion holes in the fixing frame 82 through which the installation screws 85 are inserted is formed to be slightly larger than the outer diameter of the male threads of the installation screws 85. Therefore, when fixing the fixing frame 82 to the holder 83, it is necessary to fine-tune the position of the fixing frame 82 so that the window holes 82a of the fixing frame 82 are properly positioned relative to the gas valve 80a attached to the holder 83, which requires a lot of time and effort.

[0011] Furthermore, if the gas valve mounting device 80 is used for retrofitting, in which the installation of the gas valve 80a begins after the construction of the wall panel 90, there are cases where the mounting plate portion 81c and the support plate portion 81d interfere with the edge of the through-hole 90a of the wall panel 90, preventing the bracket 81 from being moved from the room to the outside through the through-hole 90a in the wall panel 90. In such cases, there are inconveniences such as having to widen the through-hole 90a or being unable to install the gas valve as a retrofit. [Means for solving the problem]

[0012] The present invention has been made to solve at least one of the above problems, and a gas valve mounting device according to one aspect of the present invention is a device for mounting a gas valve to a plate-shaped interior material that separates the interior from the outside and has a through-hole formed therein, a fixing frame disposed on a front surface of the interior material and having a window hole facing the through hole; a bracket that is disposed on the rear surface of the interior material, has a frame plate portion in which a window hole that faces the through hole is formed, and is connected to the fixed frame by a first connecting means; a holder that is disposed on the rear side of the interior material, to which a gas cock is attached with a plug portion facing the through-hole, and that is connected to the fixing frame by a second connecting means; The device is characterized by comprising a spacer that is positioned and clamped between the holder and the fixed frame.

[0013] According to the above configuration, it is possible to provide a gas valve mounting device in which a gas valve attached to a holder on the outdoor side is positioned at an appropriate position relative to a fixing frame on the indoor side of the wall panel.

[0014] Preferably, the bracket has a mounting plate portion extending from the outer edge of the frame plate portion in a direction opposite to the interior material, and this mounting plate portion is attached to a support material that supports the interior material from its back surface. According to the above-mentioned configuration, the mounting plate portion of the bracket is attached to the support material of the interior material, so that the gas valve mounting device can also be supported by the support material. The bracket can also be attached to the support material before the interior material is installed.

[0015] Preferably, the bracket has a support plate portion extending from an inner edge portion of the frame plate portion in a direction opposite to the interior material, and an engagement hole extending in the extending direction of the support plate portion is formed in the support plate portion, the holder has a bottom plate portion that holds the gas valve, and an arm plate portion that is provided on an edge of the bottom plate portion and supported by an engagement hole of the bracket, The arm portion is movable in the direction in which the engagement hole extends. According to the above configuration, the holder can be movably supported on the bracket, and the holder can be positioned in an appropriate position on the exterior side before the interior material is installed.

[0016] Preferably, the bracket has a protruding plate portion extending from the inner edge of the frame plate portion in the opposite direction to the interior material, and the holder has an abutting plate portion extending from the edge of the bottom plate portion toward the interior material, and when the arm plate portion of the holder is supported in the engaging hole of the bracket, the abutting plate portion abuts against the protruding plate portion. According to the above configuration, when the holder is supported by the bracket, the abutment plate portion of the holder abuts against the protruding support plate portion of the bracket, thereby suppressing wobble of the abutment plate portion of the holder in the plate surface direction.

[0017] Preferably, the spacer is connected to the holder by a third connecting means and has a frame portion in which a window portion facing the window hole of the fixed frame is formed, and a handle portion is provided within the window portion and is removably supported by the frame portion and extends toward the window hole of the fixed frame. According to the above configuration, the holder to which the gas valve is attached and which is movably supported on the bracket can be pulled by pulling the handle portion of the spacer connected to the holder, thereby improving the workability of installing the gas valve.

[0018] A gas valve mounting device according to another aspect of the present invention is a device for mounting a gas valve to a plate-shaped interior material that separates an indoor space from an outdoor space and has a through-hole formed therein, a first metal fitting disposed on the rear side of the interior material; a plate-shaped second fitting arranged on the front side of the interior material, having a window hole formed therein that faces the through hole of the interior material, and connected to the first fitting via the through hole so as to be pressed against the interior material; a holder to which a gas valve, which is disposed on the rear side of the interior material and has a plug portion facing the through-hole, is attached directly or via a fixture provided on the gas valve, and which is connected to the second fitting via the through-hole directly or via the fixture, A positioning member for positioning the second fitting relative to the holder or the mounting fixture is provided between the second fitting and the holder or the mounting fixture.

[0019] According to the above configuration, the positioning member can position the second fitting relative to the holder or installation fixture, and thus the second fitting can be positioned relative to the gas valve fixed to the holder. This eliminates the need for fine adjustment of the position of the second fitting, making it easy to install the gas valve.

[0020] Preferably, the first metal fitting has a frame plate portion having a window hole formed therein that faces the through hole of the interior material and that is used to connect to the second metal fitting, an attachment plate portion that extends outward from the outer edge of the frame plate portion to the interior material and is attached to a support material that is arranged along the back surface of the interior material, and a support plate portion that extends outward from the inner periphery of the window hole in the frame plate portion to support the holder so that it can move inward and outward from the interior material, and the attachment plate portion and the support plate portion can be removed from the frame plate portion.

[0021] According to the above configuration, it is possible to accommodate not only "pre-installation" but also "post-installation" of the gas valve. In the case of "pre-attachment," before the interior material is installed, the mounting plate portion of the first fitting is attached to the support material of the interior material, and the holder with the gas valve attached is supported on the support plate portion of the first fitting to temporarily install the gas valve.After the interior material is installed, the second fitting can be positioned relative to the holder or installation tool using a positioning member passed through the through hole, and connected to the holder and to the frame plate portion of the first fitting. In the case of "retrofitting," by cutting out the mounting plate portion and support plate portion of the first metal fitting from the frame plate portion, it is possible to prevent the first metal fitting, which is being moved from inside the room to outside, from interfering with the edge of the through hole in the interior material.

[0022] Preferably, a protrusion is formed on either the positioning member or the holder or mounting device, and a recess is formed on the other, and by inserting the protrusion into the recess, the positioning member and the holder or mounting device are positioned and prevented from shifting in a direction intersecting their opposing directions. According to the above configuration, the positioning member can be positioned easily and accurately with respect to the holder or the installation tool.

[0023] Preferably, the positioning member has a frame portion that has a window portion that faces the window hole of the second fitting and abuts against the back surface of the second fitting, and an engaging protrusion that extends toward the other is formed at an opposing position on the inner periphery of either the window portion of the positioning member or the window hole of the second fitting, and an engaging recess with which the engaging protrusion engages is formed on the inner periphery of the other. According to the above configuration, the second fitting can be positioned accurately and easily relative to the positioning member by engaging the engaging protrusion with the engaging recess. The second fitting is positioned relative to the positioning member using its window hole as a reference, and therefore the window hole of the second fitting is appropriately positioned relative to the gas valve attached to the holder.

[0024] Preferably, a fitting cylindrical portion that fits into the plug portion of the gas valve attached to the holder is provided within the window portion of the positioning member and is supported by a bridging portion that extends from the inside of the frame portion into the window portion, and the bridging portion can be removed from the frame portion. According to the above-mentioned configuration, the fitting cylindrical portion and the plug portion of the gas valve are used to position the positioning member, thereby improving positioning accuracy. Furthermore, since the fitting cylindrical portion that fits into the plug portion is cut off by removing the bridge portion from the frame portion, the use of the gas valve attached to the interior material is not hindered.

[0025] Preferably, the positioning member has a handle portion extending in a direction opposite to the holder and is connected to the holder or the installation tool. According to the above configuration, by pulling the handle, not only the positioning member but also the holder and the gas valve can be pulled in. For example, when working through the through hole in the process of installing the gas valve, the positioning member, the holder, and the gas valve can be pulled in all at once, which improves the workability of installing the gas valve. [Effects of the Invention]

[0026] According to the present invention, the gas cock can be easily attached. [Brief explanation of the drawings]

[0028] [First embodiment] A first embodiment of the present invention will be described below with reference to Figures 1 to 11. In this embodiment, the present invention is applied to a gas valve mounting device that mounts a gas valve on a wall panel that serves as an interior material that separates the indoors and outdoors and has a through-hole. In the following description, the indoor side of the wall panel in the indoor / outdoor direction will be referred to as the front side, and the outdoor side will be referred to as the rear side. Also, left and right refer to the left and right when looking from the indoor side toward the outdoor side.

[0029] The gas valve mounting device 1 has, as its main components, a bracket 10 (first fitting), a holder 20, a spacer 30 (positioning member), and a fixing frame 40 (second fitting), as shown in Figure 1. The bracket 10, holder 20, and fixing frame 40 are formed by pressing and punching metal plate material.

[0030] The bracket 10 is disposed on the rear side of the wall plate 2 (see FIG. 7) and has a substantially rectangular frame plate portion 11 as shown in FIGS. 1 and 3(A), which faces the rear surface of the wall plate 2. The frame plate portion 11 has a substantially rectangular window hole 12 formed therein that faces the through hole 2a (see FIG. 7) in the wall plate 2. Fixing pieces 13 are provided on the upper and lower parts of the inner periphery of the window hole 12, respectively, which protrude toward the inside of the window hole 12 and are used for connection to a fixing frame 40, which will be described later. Each fixing piece 13 has a screw hole 13a formed therein.

[0031] A pair of support plates 14 are provided on one of the left and right sides (the left side in this embodiment) of the inner periphery of the window hole 12 (the inner edge of the frame plate portion) so as to extend rearward perpendicular to the frame plate portion 11. An engagement hole 15 extending in the front-to-rear direction is formed in each support plate portion 14. The front end of the engagement hole 15 forms an engagement piece insertion opening 15a which is wider than the remaining portion of the engagement hole 15.

[0032] A protruding and supporting plate portion 16 is provided between the pair of support plates 14, extending from the inner periphery of the window hole 12 in the same direction as the support plates 14. A notched groove 16g is formed in the plate surface at the base end of the protruding and supporting plate portion 16, and on the extension of this, notched grooves 14g are also formed above and below the engaging piece insertion opening 15a in each support plate portion 14. The notched grooves 14g, 16g are easily broken and can be broken, for example, with pliers, allowing the portions behind the notched grooves 14g, 16g to be removed.

[0033] Two vertically elongated lightening holes 17 are formed, one above the other, in a position to the left of the window hole 12 in the frame plate portion 11. A notched groove 17g is formed in the front surface of the frame plate portion 11 along the vertical bisector of the lightening holes 17, making them easy to break and capable of being broken with pliers, for example, and the breaking allows the portion to the left of the notched groove 17g to be removed.

[0034] An attachment plate 18 is provided at the outer edge (left edge in this embodiment) of the frame plate 11 so as to protrude rearward perpendicular to the frame plate 11. A pair of elongated holes 19 are formed at the upper and lower ends of the attachment plate 18 and extend in the front-to-rear direction.

[0035] The holder 20 is disposed on the rear side of the wall plate 2, and as shown in Figures 1 and 3(B), has a substantially rectangular bottom plate portion 21. Four screw holes 21a for attaching the gas valve 3 are formed in this bottom plate portion 21, with one pair of holes spaced apart in the horizontal direction and another pair spaced apart in the vertical direction. Support piece portions 22 extending forward perpendicular to the bottom plate portion 21 are provided at both ends of the upper and lower sides of the bottom plate portion 21.

[0036] The tip of each support piece 22 is bent outward at a right angle to form a fixed piece 23. Each fixed piece 23 has a screw hole 23a formed therein, and a notched recess 23b (recess) formed by cutting out one corner of the tip in a rectangular shape. Each notched recess 23b is formed so that the corners of the notched recess 23b of the laterally adjacent fixed piece 23 face each other.

[0037] A pair of arm plate portions 24 are provided on one of the left and right sides of the bottom plate 21 (the left side in this embodiment) and extend forward from the upper and lower ends of the side perpendicular to the bottom plate 21. The tip of each arm plate portion 24 forms an L-shaped engagement piece 25 that is bent outward at a right angle. The tip side of each engagement piece 25 forms a stopper piece 25a that is wider than the base end side.

[0038] The engagement piece 25 is movable within the engagement hole 15 by inserting the retaining piece 25a into the engagement piece insertion hole 15a formed in the support plate 14 of the bracket 10, and is prevented from coming off by the retaining piece 25a within the engagement hole 15 other than the engagement piece insertion hole 15a. As a result, the holder 20 is supported by the bracket 10 so as to be movable in the front-rear direction.

[0039] Between the pair of arm plate portions 24, an abutment plate portion 26 is provided, extending from the left side of the bottom plate 21 in the same direction as the arm plate portions 24. When the holder 20 is supported by the bracket 10, the abutment plate portion 26 abuts against the protruding support plate portion 16 of the bracket 10. The holder 20, which is supported by the protruding support plate portion 16 and prevented from coming off by the retaining piece portion 25a, is prevented from wobbling left and right.

[0040] A notched groove 26g extending in the vertical direction is formed in the plate surface on the outer side of the base end of the abutment plate portion 26, and a notched groove 24g is also formed on the extension of this groove in each arm plate portion 24. The notched grooves 24g, 26g are easily broken and can be broken, for example, with pliers, and the breaking allows the portions forward of the notched grooves 24g, 26g to be removed.

[0041] 1, the spacer 30 is disposed between the holder 20 and a fixed frame 40, which will be described later, and has a frame portion 31 on the front side, which is the fixed frame 40 side, and four legs 37 on the rear side, which is the holder 20 side, as shown in FIGS. 1 and 4. The frame portion 31 is formed in a substantially rectangular shape, and a window portion 32, which faces the bottom plate portion 21 of the holder 20, is formed in the frame portion 31 in a substantially rectangular shape.

[0042] Engagement protrusions 33 are formed in the center of two opposing side portions (upper and lower portions in this embodiment) (inner edge portions of the frame portion) on the inner periphery of the window portion 32, protruding forward from the front end face of the frame portion 31. The outer portions in the vertical direction of each engagement protrusion 33 are arc-shaped and protrude outward from the inner periphery of the window portion 32 when viewed from the front (FIG. 7(B)).

[0043] A fitting cylindrical portion 34 with its axis oriented in the front-to-rear direction is provided within the window portion 32. The fitting cylindrical portion 34 has an inner diameter large enough to fit the plug portion 3a of the gas cock 3, and is supported by a pair of bridge portions 35 extending from the inside of the frame portion 31 into the window portion 32.

[0044] The pair of bridging portions 35 each extend from a position midway in the front-to-rear direction between the centers of two opposing side portions (upper and lower portions in this embodiment) (inner edges of the frame) on the inner periphery of the window portion 32, and are connected to the rear end of the fitting cylinder portion 34. A notched groove 35g is formed at the base end of each bridging portion 35 to facilitate breaking, and breaking allows the tip side of the bridging portion 35 and the fitting cylinder portion 34 to be removed from the frame portion 31. This allows the gas valve 3 attached to the wall panel 2 to be used without being hindered.

[0045] The fitting cylinder 34 has a plate-shaped handle 36 integrally formed on the outer periphery of the tip. In this embodiment, the handle 36 is provided on the right side of the fitting cylinder 34, facing the right side of the frame 31, and extending forward in the direction facing the holder 20.

[0046] Legs 37 having a generally rectangular cross section and extending rearward are provided at the four corners of the frame 31. Each leg 37 has a screw insertion hole 37a penetrating the spacer 30 from front to rear, and has a contact surface 37b at its rear end that contacts the fixing piece 23 of the holder 20.

[0047] A protrusion 38 is formed at one corner of each contact surface 37b so as to extend rearward, and the cross section of the base end side of the protrusion 38 is generally rectangular. Each protrusion 38 is disposed at a corner on the outer side in the vertical direction and the inner side in the left-right direction of each contact surface 37b.

[0048] The projections 38 of the four legs 37 are inserted into the notched recesses 23b of the four fixing pieces 23 of the holder 20, respectively, whereby the spacer 30 and the holder 20 are positioned and prevented from shifting in a direction intersecting the opposing direction of the spacer 30 and the holder 20. At this time, the screw insertion holes 37a of the legs 37 and the screw holes 23a of the fixing pieces 23 are aligned.

[0049] The opening end faces 31a of the two screw insertion holes 37a located diagonally on the frame portion 31 (top right and bottom left in this embodiment) are formed at a position recessed rearward from the front end face 31b of the frame portion 31, and the front end face 31b is formed flush on all four sides so as to abut against the fixed frame 40 described later.

[0050] The length of the leg 37 of the spacer 30 is set so that when the spacer 30 is positioned relative to the holder 20 and abuts against the fixed frame 40, the plug portion 3a of the gas valve 3 attached to the holder 20 is at a predetermined position in the front-to-rear direction from the fixed frame 40.

[0051] 1 and 2, the fixing frame 40 is formed in the shape of a plate with a rounded rectangular outer shape, and is placed on the front side of the wall panel 2. A window hole 41 is formed in approximately the center of the fixing frame 40, facing the through hole 2a (see FIG. 8) of the wall panel 2 and the window portion 32 of the spacer 30, and horizontally long holes 43 are formed above and below the window hole 41, and screw insertion holes 44 are formed at the upper left and lower right of the window hole 41.

[0052] The window hole 41 is generally rectangular and has approximately the same dimensions as the window portion 32 of the spacer 30. Arc-shaped engagement recesses 42 are formed in the centers of two opposing sides (upper and lower sides in this embodiment) of the inner periphery of the window hole 41 (the inner edge of the second metal fitting).

[0053] The upper and lower engaging protrusions 33 of the spacer 30 engage with the upper and lower engaging recesses 42, respectively. As a result, the fixed frame 40 is positioned relative to the spacer 30 using the window hole 41 as a reference, and is therefore positioned relative to the holder 20. At this time, the plug portion 3a of the gas cock 3 attached to the holder 20 is positioned at an appropriate position within the window hole 41 of the fixed frame 40.

[0054] Next, a method for mounting the gas valve 3 on the wall panel 2 using the gas valve mounting device 1 configured as described above will be described with reference to Figures 5 to 10. This mounting method is a pre-installation method in which the gas valve 3 is temporarily mounted on a stud 4 (support material) that is placed along the back surface of the wall panel 2 before the wall panel 2 is constructed.

[0055] First, to attach the bracket 10 to the stud 4, as shown in Figure 5(A), the mounting plate portion 18 is butted against the side of the stud 4 so that the frame plate portion 11 is flush with the front of the stud 4, and wood screws WS inserted through the long holes 19 (see Figure 3(A)) are screwed into the stud 4.

[0056] Next, to secure the gas valve 3 to the holder 20, as shown in Figures 5(A) and (B), with the plug portion 3a of the gas valve 3 facing forward and the gas pipe connection portion 3c facing downward in the piping direction, the screws 5 inserted into the screw insertion holes 3b (see Figure 1) of the gas valve 3 are screwed into the screw holes 21a (Figure 3(B)) spaced apart laterally in the bottom plate portion 21 of the holder 20. A protective cap 3d is attached to the plug portion 3a, and a flexible pipe (not shown) is connected to the gas pipe connection portion 3c.

[0057] Next, to support the holder 20 on the bracket 10, the upper and lower retaining pieces 25a (Fig. 3(B)) on the left side of the holder 20 are passed through the engagement piece insertion holes 15a (Fig. 3(A)) of the upper and lower support plate parts 14 of the bracket 10, respectively, and the engagement pieces 25 are inserted into the engagement holes 15. Thereafter, the holder 20 is moved to a rear position as shown in Fig. 6(A) to temporarily attach the gas valve 3.

[0058] Next, the wall panel 2 is installed, and as shown in Figure 7, through-holes 2a are formed by cutting the wall panel 2 from the inside of the room along the window holes 12 (Figure 3(A)) in the frame panel portion 11 of the bracket 10. A spacer 30 is passed through the through-holes 2a, and the four protrusions 38 of the spacer 30 are inserted into the four notched recesses 23b of the holder 20, respectively. This allows the spacer 30 and holder 20 to be positioned easily and accurately.

[0059] At this time, the protective cap 3d attached to the plug portion 3a of the gas cock 3 fits into the fitting cylindrical portion 34 of the spacer 30, contributing to improving the accuracy of positioning the spacer 30 and the holder 20. With the spacer 30 and the holder 20 positioned, screws 6 (third connecting means) are inserted into the screw insertion holes 37a at the upper right and lower left of the spacer 30 and screwed into the fixing piece portion 23, thereby connecting and fixing the spacer 30 and the holder 20.

[0060] Next, as shown in Figure 8, screws 7 (first connecting means) are passed through the upper and lower elongated holes 43 of the fixing frame 40 and screwed into the threaded holes 13a of the fixing pieces 13 of the bracket 10, thereby temporarily connecting the fixing frame 40 to the bracket 10. Next, as shown in Figure 9(A), the handle portion 36 of the spacer 30 is pulled toward you. This allows the spacer 30, holder 20, and gas valve 3 to be pulled together, making the installation of the gas valve easier.

[0061] 9(B), the upper and lower engaging protrusions 33 of the pulled spacer 30 are engaged with the upper and lower engaging recesses 42 of the window hole 41 of the fixed frame 40. This allows the fixed frame 40 and spacer 30 to be positioned easily and accurately, and the plug portion 3a of the gas valve 3 attached to the holder 20 is positioned at an appropriate position within the window hole 41 of the fixed frame 40.

[0062] Next, screws 8 (second connecting means) are passed through the upper left and lower right screw insertion holes 44 of the fixed frame 40 and screwed into the fixed piece portion 23 of the holder 20 via the screw insertion hole 37a of the spacer 30, thereby connecting and fixing the fixed frame 40, spacer 30 and holder 20.

[0063] Next, the fixing frame 40 that has been temporarily fixed to the bracket 10 is completely fixed by tightening the screws 7, thereby pressing the fixing frame 40 against the wall panel 2. Next, as shown in Figure 10, the notched groove 35g of the bridge portion 35 is broken with pliers or the like, and the bridge portion 35 and the fitting cylindrical portion 34 are cut off from the frame portion 31, and the protective cap 3d is removed from the plug portion 3a. Thereafter, the decorative plate 9 shown in Figure 1 is attached to the fixing frame 40, thereby completing the installation of the gas valve 3 to the wall panel 2.

[0064] In this embodiment, the gas pipe connection portion 3c faces downward when the gas valve 3 is fixed to the holder 20 (FIG. 5), but depending on the piping direction, it may face upward as shown in FIG. 11(A) or to the right as shown in FIG. 11(B). When facing right, the screws 5 are threaded into the screw holes 21a (FIG. 3(B)) spaced apart in the vertical direction in the bottom plate portion 21 of the holder 20.

[0065] According to the above embodiment, the spacer 30 can position the fixed frame 40 relative to the holder 20, and in turn, the fixed frame 40 can be positioned relative to the gas valve 3 fixed to the holder 20. This eliminates the need for fine adjustment of the position of the fixed frame 40, and allows for easy installation of the gas valve 3.

[0066] Next, other embodiments of the present invention will be described. Note that in the following embodiments, only the configurations that are different from the above embodiment will be described, and similar components will be assigned the same reference numerals and their description will be omitted.

[0067] [Second embodiment] A second embodiment of the present invention will be described below with reference to Figures 12 to 20. The gas valve mounting device of this embodiment is used in a so-called retrofit installation method, in which the installation of the gas valve begins after the wall panel has been installed. The bracket is not attached to a stud.

[0068] The gas valve mounting device 1A has, as its main components, a bracket 10A, a holder 20A, a spacer 30, and a fixing frame 40, as shown in FIGS. The bracket 10A is obtained by breaking off the notched grooves 17g, 14g, and 16g of the frame plate portion 11, support plate portion 14, and protruding support plate portion 16 of the bracket 10 (FIG. 3(A)) of the first embodiment. The holder 20A is obtained by breaking off the notched grooves 24g and 26g of the arm plate portion 24 and abutment plate portion 26 of the holder 20 (FIG. 3(B)) of the first embodiment.

[0069] A method for mounting a gas valve 3 on a wall plate 2 using a gas valve mounting device 1A will be described with reference to Figures 15 to 19. Prior to mounting the gas valve 3, the wall plate 2 (see Figure 18) is constructed, and a through hole 2a is formed in the wall plate 2.

[0070] First, as shown in FIG. 15, the gas valve 3 is attached to the holder 20 with the gas pipe connection part 3c facing downward in the piping direction, and the spacer 30 is connected and fixed to the holder 20A with the screws 6.

[0071] Next, as shown in Fig. 16, the fixing frame 40, spacer 30, and holder 20A are connected and fixed with screws 8, and then the bridging portion 35 and fitting cylindrical portion 34 are cut away from the frame portion 31 of the spacer 30 as shown in Fig. 17. In addition, the flexible pipe F, which has been pulled out from the back side of the wall panel 2 into the room through the through-hole 2a, is passed through the window hole 12 in the bracket 10A and connected to the gas pipe connection portion 3c of the gas valve 3.

[0072] Next, as shown in Figure 18, the bracket 10A is moved to the back side of the wall panel 2 through the through hole 2a, and then the fixing frame 40 is connected and fixed to the bracket 10A with screws 7. As shown in Figure 19, the protective cap 3d is removed from the plug portion 3a, and then the decorative plate 9 is attached to the fixing frame 40, thereby completing the installation of the gas valve 3.

[0073] In this embodiment, as shown in FIG. 20, when the gas valve 3 is fixed to the holder 20A, the gas pipe connection portion 3c may be directed leftward, and the gas valve 3 can be adapted to any piping direction, up, down, left, or right.

[0074] According to this embodiment, the bracket 10A is obtained by breaking the notched grooves 17g, 14g, and 16g of the bracket 10 of the first embodiment, and therefore can be moved from inside the room to outside through the through hole 2a of the wall panel 2 without interfering with the hole edge of the through hole 2a.

[0075] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. In the above embodiment, the protrusions are formed at the tip ends of the legs of the spacer and the notched recesses are formed in the fixing pieces of the holder, but it is also possible to form the recesses in the spacer and the protrusions in the holder. In the above embodiment, the gas valve is attached directly to the holder, but it is also possible to attach a mounting fixture to the gas valve and then attach the mounting fixture to the holder, or to provide a spacer between the mounting fixture and the fixed frame so that it is connected to the mounting fixture, or to form a recess in the mounting fixture into which the protrusion of the spacer is inserted, or to form a protrusion that is inserted into the recess of the spacer. In the above embodiment, an engagement protrusion is formed on the inner edge of the frame portion of the spacer and an engagement recess is formed on the inner edge of the fixed frame, but an engagement recess may be formed on the inner edge of the frame portion of the spacer and an engagement protrusion may be formed on the inner edge of the fixed frame. The interior material to which the gas valve is attached may be a floorboard. In the first embodiment, the bracket is attached to a stud (support material) on the back side of the interior material, but it may also be attached to a crosspiece, joist, or the like as a support material.
