Description

Technical Field

[0001] The present invention relates to a gas plug housing box, particularly to a gas plug housing box that houses a gas plug body installed on the back side of a wall and protects it in an airtight state.

Background Art

[0002] As a housing box for an embedded gas plug, for example, one as shown in FIG. 7 is known. This is a rectangular metal box body (55) fixed to the back side of the wall surface (5) so as to cover a rectangular opening (50) formed in the wall plate (5) in a state where the gas plug body (4) installed on the back side of the wall plate (5) is housed, and it is open toward the opening (50). A pipe connection part (41) is penetrated and fixed to a pipe hole (54) formed on the lower surface of the box body (55), and through this, the gas plug body (4) and the gas pipe (42) are connected.

[0003] The gas plug body (4) is installed in the box body (55) so that the plug part (40) for detachably connecting a socket faces the opening (50), and a decorative plate (51) is attached and fixed to the surface of the wall plate (5) so as to cover the opening (50). At a predetermined position of the decorative plate (51) corresponding to the tip of the plug part (40), a circular window part (52) through which the socket can be inserted and a lid body (53) capable of opening and closing the window part (52) are provided. When the decorative plate (51) is attached so as to cover the opening (50) from the front side of the wall plate (5) and the window part (52) is closed with the lid body (53), the space surrounding the gas plug body (4) on the back side of the wall plate (5) is blocked by the box body (55), and the airtightness inside the box body (on the back side of the wall plate (5) is ensured. Thereby, in winter, even if the lid body (53) of the decorative plate (51) is opened, it is possible to prevent the inconvenience that the cold air on the back side of the wall plate (5) enters the room, and in the event of a fire, there is no risk that flames or smoke coming along the inside of the wall plate (5) will spout into the room from the opening (50).

[0004] Furthermore, it is desirable that piping holes (54) be provided on all structural surfaces of the box body (55) on all sides (top, bottom, left, and right) so that gas piping (45) can be routed from any direction (top, bottom, left, or right) relative to the box body (55). For example, in the invention of Patent Document 1, as shown on the top surface of the box body (55) in Figure 7, the piping holes (54) are blocked by a separately provided blocking plate (45), and the blocking plate (45) can be removed to open the piping holes (54) as needed. A pair of bendable leg pieces (44) are provided at both ends of the diameter of the blocking plate (45), and the blocking plate (45) is attached around the piping holes (54) so ​​as to cover the piping holes (54) from the inside of the box body (55), while the pair of leg pieces (44) protrude to the outside of the box body (55), and are bent and locked to fit along the outer surface of the box body (55), thereby enabling the blocking plate (45) to be installed in the piping holes (54). The closing plate (45) can be removed by raising the legs (44) relative to the closing plate (45) and pulling them out through the piping hole (54) into the inside of the box body (55).

[0005] Alternatively, as shown in the other example on the side of the box (55) in the same figure, a cut (43) can be made along the outline of the pipe hole (54), and if necessary, the worker can punch along the cut (43) to open the pipe hole (54).

[0006] Thus, in cases where multiple piping holes (54) are pre-formed on multiple structural surfaces of the box body (55), the piping holes (54) can be opened on desired structural surfaces of the box body (55) according to the direction of gas piping installation by removing the blocking plate (45) as needed at the work site, or by punching through the cuts (43) if cuts (43) are formed along the contour lines of the piping holes (54), thus providing a user-friendly gas valve housing box. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2018-40468 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, in the case where each component surface of the box body (55) has pre-opened piping holes (54), a separate closing plate (45) must be prepared for each piping hole to close off unnecessary piping holes (54), and the process of attaching and detaching the closing plates (45) to each piping hole (54) is cumbersome. On the other hand, in the case where the piping holes (54) are opened by punching along a cut (43), when punching out the area enclosed by the cut (43), the force in the punching direction acts on the area around the cut (43), which may deform the area around the piping hole (54). If the area around the piping hole (54) on the component surface is deformed, it becomes difficult to fix the piping connection part (41) to the piping hole (54), and the airtightness inside the box body (55) is compromised.

[0009] The present invention aims to provide a gas valve housing box, which consists of a metal box that houses and protects a gas valve body installed on the back side of a wall panel and is attached to the back side of an opening in the wall panel while ensuring airtightness, and which has a sealing structure that allows the piping hole that is open on the structural surface of the box to be easily opened and closed as needed. [Means for solving the problem]

[0010] The technical means of the present invention, which were taken to solve the above problems, A box-shaped structure that is attached to the back of a wall panel, opening towards an opening provided in the wall panel and housing the gas valve body, The box-shaped structural surface has a pipe connection portion for the gas valve body or a pipe hole for inserting the gas pipe, The aforementioned piping hole is closable by a closing piece that is part of the aforementioned structural surface, and the base end of the closing piece is set to be bendable. Occasionally, The aforementioned closing piece is provided on the outer surface of the constituent surface and is formed to be of a size and shape that can completely close the piping hole from the outside. Although it covers the piping hole, it is not joined to its periphery, but rather is in a manner that it is in close contact with it. That is the case.

[0011] The above technical means work as follows: For example, if piping holes are formed on each of the multiple structural surfaces that make up the box, each of these holes is kept closed by a closing piece that is part of the structural surface. In other words, before use, all the piping holes in the box are closed by the closing pieces.

[0012] Then, the base end of the blocking piece that is blocking the pipe hole in one of the structural walls located on the back side of the wall panel in the direction in which the gas piping is laid is bent to open the pipe hole. Since the blocking piece is made up of a part of the structural surface of the box, it remains connected to the structural surface even after being opened. Therefore, if it is necessary to close the pipe hole that has been opened, the blocking piece, with its base end bent, can be tilted in a direction that overlaps with the structural surface, and the pipe hole will return to its original state of being closed by the blocking piece.

[0013] After opening the designated piping hole, the piping connection part of the gas valve body is attached to the piping hole in the same manner as the installation structure of a conventional buried gas valve, and the gas valve body and the box body are fastened to the pillar on the back of the wall panel via a back plate using screws or the like, so that the box body is facing outwards toward the wall panel. twist Secure it in place. Then, attach the wall panel so that the opening is located in the corresponding position on the box, and attach the decorative panel to the surface of the wall panel so that it covers the opening, and the installation of the buried gas valve is completed. Furthermore, since the closing piece provided on the outer surface of the structural element is designed to be folded outwards to open it, opening and cutting the closing piece is even easier, and it is possible to prevent the inconvenience of the cut closing piece falling into the box and interfering with pipe connections.

[0014] In the gas valve housing box described above, preferably, "the base end of the blocking piece is a detachable small piece." The blocking piece is connected to the structural surface via a small piece, and to open the pipe opening, the small piece of the designated blocking piece can be bent. After that, the blocking piece that is no longer needed can be easily separated from the structural wall by cutting the small piece. In this way, by making the base end of the blocking piece a small piece, the opening and cutting operations of the blocking piece are made easy, the pipe opening can be opened without deforming the area around the pipe opening, and the blocking piece after opening can be easily separated and used as a pipe opening.

[0015] In the gas valve housing box described above, preferably, "at least one cut is formed along the base end of the closing piece." By providing at least one slit at the base end of the closing piece, the closing piece and the structural surface are connected only at the connecting portions on both sides of the slit. To open the closing piece, this connecting portion can be bent, and the closing piece that is no longer needed can be easily removed from the structural surface by cutting the connecting portion.

[0016] In the gas valve housing box described above, preferably, a thin groove is formed along the base end of the closing piece. Because the blocking piece can be opened by bending or cutting along the thin groove, opening and closing the blocking piece is easy. [Effects of the Invention]

[0018] Because of the above configuration, the present invention has the following unique effects. Since the blocking piece that holds the pipe opening closed is made from a part of the box's structural surface, there is no need to prepare a separate part for closing the pipe opening. Therefore, the number of parts can be reduced. Since the pipe hole can be opened simply by bending the base end portion of the closing piece, the operation of opening the pipe hole is easy and the workability is improved. Further, since no deformation stress is applied to the component surface where the pipe hole is formed during the opening operation, there is no inconvenience that the component surface is inadvertently deformed or damaged during the opening operation. Therefore, the operator can easily open only the desired pipe hole at the site without impairing the airtightness inside the box. Since the closing piece after bending remains continuously connected to the component surface unless the base end portion is forcibly separated, if the closing piece is overlapped with the component surface so as to cover the pipe hole, the pipe hole can be re-closed, and the closing piece can be repeatedly used according to the situation.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described based on the drawings. Figures 1 and 2 are perspective views of the gas valve housing box of the present invention. Figure 1 shows the closed state of the closing piece (2), and Figure 2 shows the open state of the closing piece (2). Figure 3 shows the state with the closing piece (2) removed, and Figure 4 is an explanatory diagram of the usage state.

[0021] The gas valve housing box of the present invention is a vertically elongated rectangular metal box (1) that is open on one side, comprising a left side (11) having two horizontally elongated slits (11a) (11b) that open to the side on which the wall panel is installed, a right side (12) located opposite to the left side, an upper surface (13) and a lower surface (14), and a vertically elongated rectangular rear surface (15). As shown in Figures 2 and 3, on the upper and lower surfaces (13) and (14), one roughly hexagonal pipe hole (10) is provided at each location on the right side in the drawing, for inserting the pipe connection portion (30) (see Figure 4) of the gas valve body (3).

[0022] Extension pieces (21) and (22) extend vertically from both the upper and lower ends of the left and right sides (11) and (12), and a closing piece (2) of a size and shape capable of completely closing the pipe hole (10) from the outside extends from the extension end of the extension piece (22) on the right side (12) that is close to the pipe hole (10). Furthermore, a notch (20) is formed in the center of the base end of the closing piece (2), which corresponds to the boundary between the closing piece (2) and the extension piece (22), and the closing piece (2) and the extension piece (22) are connected only at the connecting portions (23) on both sides of the notch (20).

[0023] The upper and lower extension pieces (21) and (22) are bent at a right angle toward the upper and lower surfaces (13) and (14) at the boundary with the left and right side surfaces (11) and (12), and are joined so that they are attached to the outer surface of the upper and lower surfaces (13) and (14), respectively. The closing piece (2) that is continuous with the extension pieces (21) and (22) covers the piping hole (10), but is not joined to its periphery, and is in a manner that is in close contact with it. In this way, the piping holes (10) formed on the upper and lower surfaces (13) and (14) are both held closed from the outer surface side by the closing piece (2) further extending from the extension piece (22) on the right side surface (12), and the airtightness of the box body (1) surrounded by the left and right sides (11) and (12), the upper and lower surfaces (13) and (14), and the rear surface (15) is ensured.

[0024] To open the blocking piece (2), as shown in Figure 2, the blocking piece (2) blocking the piping hole (10) on the upper surface (13) is bent upward, and the blocking piece (2) blocking the piping hole (10) on the lower surface (14) is bent downward, with each base end being bent outwards. Since the base ends are connected only at the connecting parts (23) on both sides of the central cut (20), they can be bent easily, and there is no inconvenience of deforming or damaging the upper and lower surfaces (13) and (14) when bending.

[0025] Since the open closing piece (2) is connected to the extension piece (22) and the connecting part (23), it can be returned to its original state by tilting it in a direction that overlaps the upper and lower surfaces (13) and (14), thereby re-closing the piping hole (10). In this way, if it is necessary to close the piping hole (10) after opening it by bending the base end of one of the closing pieces (2), it can be done quickly, thus providing a gas valve housing box that is easy to use depending on the location of the gas piping.

[0026] After determining which pipe opening (10) to be opened, the connecting portion (23) of the closing piece (2) can be cut and removed from the box body (1). Figure 3 shows the state in which the closing piece (2) on the upper surface (13) has been removed, opening the pipe opening (10) formed on the upper surface (13), while the closing piece (2) on the lower surface (14) remains closed. When removing the closing piece (2), all that is required is to cut the connecting portions (23) on both sides of the cut (20), so the closing piece (2) can be easily removed without deforming the upper surface (13), and the pipe opening (10) can be opened on the desired surface.

[0027] In the above embodiment, as shown in Figure 4, when the piping hole (10) provided on the top surface (13) is left open, the gas valve body (3) is housed inside the box (1) with the plug portion (31) facing forward and the piping connection portion (30) facing upward.

[0028] This type of box (1) is attached to the back of a plasterboard wall panel (not shown) via a metal backplate (32) which is an L-shaped fixing bracket. The gas valve body (3) is then attached to the backplate (32) via a back plate (not shown) which is fixed to the gas valve body (3).

[0029] As shown in Figure 4, the back plate (32) is a metal plate with a roughly L-shaped cross-section, consisting of a roughly rectangular frame plate (33) attached to the back surface of the wall panel and an adjustment plate (34) extending perpendicularly from one side of the outer periphery of the frame plate (33) (the left edge in the drawing). The back plate, which is fixed to the gas valve body (3), is attached to a protruding piece (35) that extends inward from the lower part of the right edge of the inner periphery of the frame plate (33). The adjustment plate (34) has two horizontally elongated holes (34a) and (34b) formed in parallel vertically at positions corresponding to the slits (11a) and (11b) on the left side surface (11) of the box body (1), and these holes are approximately the same size as the slits.

[0030] As described above, the back plate (32) to which the gas valve body (3) is fixed is attached to the pillar (6) on the back of the wall panel together with the box body (1). To do this, first, the piping connection part (30) of the gas valve body (3) is inserted through the piping hole (10) on the top surface (13) of the box body (1), and the adjustment plate (34) of the back plate (32) is attached to the inner surface of the left side (11) of the box body (1), so that the elongated holes (34a) (34b) correspond to the slits (11a) (11b).

[0031] Then, with the frame board (33) close to the back of the wall board that will be installed later, the frame board (33) is temporarily fixed to the side of the column (6) by screwing it with wood screws (not shown) so that the elongated holes (34a) (34b) of the adjustment plate (22) of the back plate (32) and the slits (11a) (11b) on the left side (11) of the box body (1) are connected. Since the elongated holes (34a) (34b) and slits (11a) (11b) are provided to extend horizontally in the front-to-back direction, the back plate (32) and box body (1) can be adjusted by moving them forward or backward by the length of the elongated holes (34a) (34b) and slits (11a) (11b).

[0032] After connecting the flexible gas pipe to the pipe connection part (30) that protrudes outward from the pipe hole (10) provided on the top surface (13) of the box body (1), which is temporarily fixed to the side of the column (6) together with the back plate (32), a wall panel is installed at a predetermined position corresponding to the inner periphery of the frame plate (33) of the back plate (32) so that an opening of a predetermined size corresponds to it, and with the surface of the frame plate (33) in close contact with the back surface of the wall panel around the opening, the wood screws are tightened firmly to fix the back plate (32) and the box body (1) to the side of the column (6). This allows the box body (1) containing the gas valve body (3) to be fixed to the back surface of the opening in the wall panel.

[0033] Subsequently, similar to conventional mounting structures, the decorative panel is attached to the surface of the wall panel via a front frame that clamps the wall panel from both sides, together with the frame plate (33) of the back plate (32), thereby completing the installation of the buried gas valve.

[0034] In the above embodiment, the piping connection portion (30) of the gas valve body (3) is structured to protrude from the piping hole (10) on the upper surface (13) of the box body (1). However, if it is desired to open the piping hole (10) on the lower surface (14) depending on the position of the gas pipe (42), the connecting portion (23) of the closing piece (2) on the lower surface (14) side can be bent downward to open the piping hole (10).

[0035] Figure 5 shows a modified example of the connection between the blocking piece (2) and the extension piece (22), in which the two are connected via a detachable small piece (24). To open the piping hole (10), the small piece (24) can be bent, and the blocking piece (2) that is no longer needed can be removed by cutting off the small piece (24). In this way, by connecting the blocking piece (2) only with the small piece (24), the opening and cutting operations become even easier, and the piping hole (10) can be opened without deforming the area around it.

[0036] Furthermore, Figure 6 shows another modified example of the connection between the closing piece (2) and the extension piece (22), in which a thin-walled groove (25) is formed along the base end of the closing piece (2). In this configuration, the closing piece (2) can be bent or cut along the thin-walled groove (25), making it easier to open and close.

[0037] In the above embodiment, piping holes (10) are provided on the upper and lower surfaces (13) and (14) of the box body (1), and each of these is configured to be openable and closable with a closing plate (2). However, the piping holes (10) and closing plates (2) may also be provided on the right side (12) or the rear surface (15). In this way, piping holes (10) are provided on multiple structural surfaces of the box body (1), and each of these can be closed to ensure airtightness with a closing piece (2). Furthermore, by opening the closing piece (2) on the desired structural surface, piping holes (10) can be provided. Thus, a user-friendly box body (1) can be provided in which the piping holes (10) can be opened at a position corresponding to the gas piping layout.

[0038] Furthermore, since the piping hole (10) can be opened simply by bending the base end of the sealing piece (2), the opening process is made easier, improving work efficiency. In addition, there is no inconvenience in deforming or damaging the area around the piping hole (10) when opening the sealing piece (2), so the airtightness inside the box (1) is not compromised by the process of opening the piping hole (10).

[0039] Furthermore, although the above embodiment described a housing box for a buried gas valve installed on the back of a wall panel, it goes without saying that it can also be installed on a floor panel in the same way. [Explanation of symbols]
