Description

The present invention relates to a gas valve mounting device for attaching a gas valve to a plate-shaped interior material that separates the interior and exterior and has a through-hole formed in it.

When attaching a gas valve to a wall panel, which is a plate-like interior material that separates the interior from the outdoors, there are two ways to do it: either the gas valve is temporarily attached to a stud 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).

As an example of a pre-installed installation, the 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 to a wall plate 90 having a through-hole 90a formed therein. It comprises a bracket (first fitting) 81 arranged on the back side of the wall plate 90, a plate-shaped fixing frame (second fitting) 82 arranged on the front side of the wall plate 90 and having a window hole 82a facing the through-hole 90a in 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, to which the gas valve 80a is attached.

The bracket 81 has a frame plate portion 81b with a window hole 81a formed therein that faces the through hole 90a in the wall plate 90; a mounting plate portion 81c that extends perpendicularly from one side of the frame plate portion 81b outward from 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 outward from the inner periphery of the window hole 81a in the frame plate portion 81b and supports the holder 83 so that it can move inward and outward from the wall plate 90.

To attach the gas valve 80a to the wall panel 90 using the gas valve mounting device 80, first align and attach the mounting plate portion 81c of the bracket 81 to the stud 91 on the back side of the wall panel 90 before constructing the wall panel 90. Next, the gas valve 80a is attached to the holder 83 via the mounting fixture 80b (Figure 22) provided on the gas valve 80a, and the holder 83 is supported on the support plate portion 81d of the bracket 81 so that it can be moved indoors and outdoors. The holder 83 is then moved to a position outdoors, thereby temporarily attaching the gas valve 80a.

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 the specified position.

Then, after placing the operation unit 84 inside the through-hole 90a so that it surrounds the plug portion of the gas valve 80a, the fixing frame 82 is attached to the front side of the wall panel 90 and aligned. Mounting screws 85 are inserted into the two insertion holes diagonally outside the window hole 82a of the fixing frame 82, passed through the operation unit 84, and screwed into the installation fixture 80b (Figure 22). This connects and secures the fixing frame 82 and holder 83.

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 secures 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. After that, 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.

Japanese Patent Application Laid-Open No. 2006-189121

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 mounting screws 85, and is then fixed to the holder 83. However, the diameter of the insertion hole in the fixing frame 82 through which the mounting screw 85 is inserted is slightly larger than the outer diameter of the male thread of the mounting screw 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 hole 82a of the fixing frame 82 is properly aligned with the gas valve 80a attached to the holder 83, which requires a lot of time and effort.

Furthermore, if the gas valve mounting device 80 is used for retrofitting, where the installation of the gas valve 80a begins after the wall panel 90 has been installed, the mounting plate portion 81c and support plate portion 81d may interfere with the edge of the through-hole 90a when moving the bracket 81 from the room to the outside through the through-hole 90a in the wall panel 90, preventing the bracket from being moved. In such cases, the through-hole 90a must be widened, or the gas valve cannot be installed as a retrofit, which is an inconvenience.

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.

The above configuration provides a gas valve mounting device that positions the gas valve attached to the holder on the outdoor side in an appropriate position relative to the fixed frame on the indoor side of the wall panel.

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.

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.

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.

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.

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-like second metal 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 metal 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.

With the above configuration, the positioning member allows the second fitting to be positioned relative to the holder or mounting fixture, and ultimately the second fitting can be positioned relative to the gas valve fixed to the holder. This eliminates the need for fine adjustments to the position of the second fitting, making it easy to install the gas valve.

Preferably, the first metal fitting has a frame plate portion having a window hole formed therein that faces the through hole in the interior material and that is used to connect to the second metal fitting; a mounting 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 in and out of the interior material, and the mounting plate portion and support plate portion can be removed from the frame plate portion.

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 attach 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.

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.

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 extending 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.
With the above configuration, the second fitting can be positioned accurately and easily relative to the positioning member by engaging the engaging projection with the engaging recess. The second fitting is positioned relative to the positioning member using the 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.

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.

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.

This invention makes it easy to install a gas valve.

[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 indoor and outdoor areas 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.

As shown in Figure 1, 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). The bracket 10, holder 20, and fixing frame 40 are formed by pressing and punching metal plate material.

The bracket 10 is positioned on the back side of the wall panel 2 (see Figure 7) and has a generally rectangular frame plate portion 11 as shown in Figures 1 and 3(A), which faces the back surface of the wall panel 2. The frame plate portion 11 has a generally rectangular window hole 12 formed therein that faces the through hole 2a (see Figure 7) in the wall panel 2. The upper and lower parts of the inner periphery of the window hole 12 each have fixing pieces 13 that protrude inward into the window hole 12 and are used to connect to the fixing frame 40, described below. Each fixing piece 13 has a screw hole 13a formed therein.

A pair of support plates 14 are provided on one of the left and right sides (in this embodiment, the left side) 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. Each support plate portion 14 has an engagement hole 15 extending in the front-to-rear direction. The front end of the engagement hole 15 forms an engagement piece insertion opening 15a, which is wider than the rest of the engagement hole 15.

A protruding support plate 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 support plate 16, and on the extension of this groove, notched grooves 14g are also formed above and below the engagement piece insertion opening 15a in each support plate 14. The notched grooves 14g, 16g are easily broken and can be broken, for example with pliers, allowing the portion behind the notched grooves 14g, 16g to be removed.

Two vertically elongated lightening holes 17 are formed in the frame plate 11 to the left of the window hole 12, arranged one above the other. A notch 17g is formed in the front surface of the frame plate 11 along the vertical bisector of the lightening holes 17, making them easier to break. They can be broken with pliers, for example, and the portion to the left of the notch 17g can be removed by breaking them.

A mounting plate 18 is provided on the outer edge of the frame plate 11 (the left edge in this embodiment) 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 mounting plate 18 and extend in the front-to-rear direction.

The holder 20 is located on the back side of the wall panel 2 and, as shown in Figures 1 and 3(B), has a generally 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 spaced apart horizontally and another pair spaced apart vertically. Support pieces 22 are provided at both ends of the upper and lower sides of the bottom plate portion 21, extending forward perpendicular to the bottom plate portion 21.

The tip of each support piece 22 forms a fixed piece 23 that is bent outward at a right angle. Each fixed piece 23 has a screw hole 23a and a rectangular cutout recess 23b (recess) formed in one corner of the tip. Each cutout recess 23b is formed so that the corners of the cutout recess 23b of the horizontally adjacent fixed piece 23 face each other.

A pair of arm portions 24 extend forward perpendicular to the bottom plate 21 from the upper and lower ends of one of the left and right sides of the bottom plate 21 (the left side in this embodiment). The tip of each arm 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 retention piece 25a that is wider than the base end.

The engagement piece 25 can move within the engagement hole 15 by inserting the retaining piece 25a into the engagement piece insertion opening 15a formed in the support plate portion 14 of the bracket 10, and is prevented from falling out by the retaining piece 25a in the engagement hole 15 other than the engagement piece insertion opening 15a. This allows the holder 20 to be supported on the bracket 10 so that it can move in the forward and backward directions.

Abutment plate portion 26 is provided between the pair of arm plate portions 24, 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 loose by the retaining piece portion 25a, is prevented from wobbling left and right.

A notched groove 26g extending vertically is formed on the outer plate surface of the base end of the abutment plate portion 26, and a notched groove 24g is also formed on each arm plate portion 24 along the extension line of this groove. The notched grooves 24g, 26g are easily broken and can be broken, for example, with pliers, allowing the portion forward of the notched grooves 24g, 26g to be removed.

As shown in Figure 1, the spacer 30 is disposed between the holder 20 and the fixed frame 40 (described below), and as shown in Figures 1 and 4, has a frame portion 31 on the front side, which faces the fixed frame 40, and four legs 37 on the rear side, which faces the holder 20. The frame portion 31 is formed in a roughly rectangular shape, and a roughly rectangular window portion 32 is formed in the frame portion 31 that faces the bottom plate portion 21 of the holder 20.

Engagement protrusions 33 that protrude forward from the front end face of the frame 31 are formed in the center of two opposing side portions (upper and lower portions in this embodiment) (inner edge portions of the frame) on the inner periphery of the window portion 32. The outer vertical portions 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 (Figure 7(B)).

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 valve 3, and is supported by a pair of bridge portions 35 that extend from the inside of the frame portion 31 into the window portion 32.

The pair of bridge portions 35 each extend from the center, in the front-to-rear direction, of two opposing side portions (in this embodiment, the upper and lower portions) (the inner edges of the frame) on the inner periphery of the window portion 32, and are connected to the rear end of the fitting tube portion 34. A notched groove 35g is formed at the base end of each bridge portion 35 to facilitate breaking, so that the tip side of the bridge portion 35 and the fitting tube portion 34 can be removed from the frame portion 31 by breaking the groove. This ensures that the gas valve 3 attached to the wall panel 2 can be used uninterrupted.

The fitting tube 34 has a plate-shaped handle 36 integral with the outer periphery of its tip. In this embodiment, the handle 36 is located on the right side of the fitting tube 34, facing the right side of the frame 31, and extending forward in the direction facing the holder 20.

Leg portions 37 with a generally rectangular cross section that extend rearward are provided at each of the four corners of the frame portion 31. Each leg portion 37 has a screw insertion hole 37a that penetrates the spacer 30 from front to rear, and an abutment surface 37b at its rear end that abuts against the fixed piece portion 23 of the holder 20.

A protrusion 38 is formed at one corner of each abutment surface 37b, extending rearward, and the cross section of the base end of the protrusion 38 is generally rectangular. Each protrusion 38 is located at the outer corner in the vertical direction and the inner corner in the horizontal direction of each abutment surface 37b.

By inserting the protrusions 38 of the four legs 37 into the notched recesses 23b of the four fixing pieces 23 of the holder 20, the spacer 30 and holder 20 are positioned and prevented from shifting in a direction intersecting the direction in which the spacer 30 and holder 20 face each other. At this time, the screw insertion holes 37a of the legs 37 and the screw holes 23a of the fixing pieces 23 are aligned.

The opening end faces 31a of the two screw insertion holes 37a located diagonally across the frame 31 (top right and bottom left in this embodiment) are recessed rearward from the front end face 31b of the frame 31, and the front end face 31b is flush with all four sides and is designed to abut against the fixed frame 40, which will be described later.

The length of the legs 37 of the spacer 30 is set so that when it 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 positioned at a predetermined front-to-rear position from the fixed frame 40.

As shown in Figures 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 Figure 8) in the wall panel 2 and the window portion 32 in the spacer 30. Long horizontal 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.

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).

The upper and lower engagement protrusions 33 of the spacer 30 engage with the upper and lower engagement recesses 42, respectively. This positions the fixed frame 40 relative to the spacer 30 using the window hole 41 as a reference, and thus positions it relative to the holder 20. At this time, the plug portion 3a of the gas valve 3 attached to the holder 20 is positioned appropriately within the window hole 41 of the fixed frame 40.

Next, a method for mounting the gas valve 3 to 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 to a stud 4 (support material) that is placed along the back surface of the wall panel 2 before the wall panel 2 is constructed.

First, to attach the bracket 10 to the stud 4, as shown in Figure 5(A), butt the mounting plate portion 18 against the side of the stud 4, aligning the frame plate portion 11 flush with the front of the stud 4, and then insert the wood screw WS through the long hole 19 (see Figure 3(A)) and screw it into the stud 4.

Next, to secure the gas valve 3 to the holder 20, as shown in Figures 5(A) and (B), the plug portion 3a of the gas valve 3 is faced forward, and the gas pipe connection portion 3c is faced downward in the piping direction. Then, the screws 5 inserted through the screw insertion holes 3b (see Figure 1) of the gas valve 3 are screwed into the laterally spaced screw holes 21a (Figure 3(B)) 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.

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)) on the upper and lower support plate parts 14 of the bracket 10, respectively, and each engagement piece 25 is inserted into each engagement hole 15. After that, the holder 20 is moved to the rear position as shown in Fig. 6(A) to temporarily attach the gas valve 3.

Next, the wall panel 2 is installed, and as shown in Figure 7, the wall panel 2 is cut out from the room along the window hole 12 (Figure 3(A)) in the frame plate portion 11 of the bracket 10 to form a through hole 2a. The spacer 30 is passed through the through hole 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.

At this time, the protective cap 3d attached to the plug portion 3a of the gas valve 3 fits into the fitting cylindrical portion 34 of the spacer 30, contributing to improved positioning accuracy between the spacer 30 and holder 20. With the spacer 30 and 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 holder 20.

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, 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, improving the ease of installation of the gas valve.

As shown in Figure 9 (B), the upper and lower engagement protrusions 33 of the pulled spacer 30 are engaged with the upper and lower engagement recesses 42 of the window hole 41 of the fixed frame 40, respectively. This allows the fixed frame 40 and spacer 30 to be positioned accurately and easily, and the plug portion 3a of the gas valve 3 attached to the holder 20 is positioned appropriately within the window hole 41 of the fixed frame 40.

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.

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.
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 FIG. 1 is attached to the fixing frame 40, thereby completing the installation of the gas valve 3 to the wall panel 2.

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

In the above embodiment, the spacer 30 allows the fixed frame 40 to be positioned 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 adjustments to the position of the fixed frame 40, making it easy to install the gas valve 3.

Next, we will explain other embodiments of the present invention. Note that in the following embodiments, only the configurations that differ from the above embodiment will be explained; similar components will be assigned the same reference numerals and their explanation will be omitted.

In this embodiment, as shown in Figure 20, when the gas valve 3 is fixed to the holder 20A, the gas pipe connection portion 3c may be oriented to the left, making it possible to accommodate piping directions of up, down, left, and right.

In this embodiment, the bracket 10A has the notched grooves 17g, 14g, and 16g of the bracket 10 in the first embodiment broken away, allowing it to be moved from inside the room to outside through the through-hole 2a in the wall panel 2 without interfering with the edge of the through-hole 2a.

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.

The present invention can be applied to a gas valve mounting device for attaching a gas valve to a plate-shaped interior material that separates the interior and exterior and has a through-hole formed in it.
