Description

[Technical field]

[0001] The present invention relates to a cover device and an installation method for an LP gas cylinder, which are used when installing an LP gas cylinder with a valve on the top near a fire equipment. [Background technology]

[0002] Non-Patent Document 1 specifies the installation of LP gas cylinders. For example, when an LP gas cylinder with a storage capacity of less than 1 ton is installed outdoors, the LP gas cylinder is specified to be installed so that the distance from fire equipment such as a water heater is more than 2 m. However, if the distance from the fire cannot be secured, a non-combustible partition is specified to be installed between the LP gas cylinder and the fire equipment. Examples of non-combustible partitions include concrete, blocks, slate, and metal plates. [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] "LP Gas Safety Operation Guide: Inspection and Investigation", Ministry of Economy, Trade and Industry, High Pressure Gas Safety Institute, 2019 15th Edition DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] However, the above-mentioned non-combustible partition wall is difficult to install in a narrow space, and depending on the position of the fire equipment and the LP gas cylinder, the non-combustible partition wall may not be installed. Even if it can be installed, there is a problem that the work of fixing the non-combustible partition wall to the ground is not easy, there is a risk of damaging the building wall, and it is necessary to obtain permission for installation from the consumer. The present invention has been made to solve the above problems, and aims to provide a cover device and an installation method for an LP gas cylinder that are easy to install when isolating the LP gas cylinder from the fire equipment. [Means for solving the problem]

[0005] The cover device of the present invention is used when an LP gas cylinder with a valve on the top is installed near a fire equipment, and is equipped with a sheet-shaped cover body that covers the outer surface of the LP gas cylinder, the cover body being formed of a non-flammable material and having at least one opening formed on the side facing away from the fire equipment.

[0006] According to this configuration, the LP gas cylinder is isolated from the fire equipment by covering it with a sheet-like cover body made of a non-flammable material, so there is no need for space to install a non-flammable partition wall, as is the case when a non-flammable partition wall is placed between the fire equipment and the LP gas cylinder, and the LP gas cylinder can be easily isolated from the fire equipment. Also, since isolation is possible simply by covering the LP gas cylinder with the cover body, installation is easy. Furthermore, since an opening is formed on the cover body on the opposite side to the fire equipment, even if LP gas leaks from the LP gas cylinder, it is possible to prevent it from flowing to the fire equipment side.

[0007] The above-mentioned cover device may further include a base on which at least one of the LP gas cylinders is placed, and the cover body may be attached to the base and configured to cover the outer surface of the LP gas cylinder placed on the base.

[0008] According to this configuration, since the base on which the LP gas cylinder is placed is provided, the LP gas cylinder can be stably placed. Also, since the cover body is attached to the base and formed integrally therewith, the cover device can be easily handled.

[0009] In the above cover device, at least one of the openings may be formed in a lower end portion of the cover body.

[0010] Since LP gas is heavier than air, if it leaks from an LP gas cylinder it will flow downward. Therefore, if an opening is formed at the bottom end of the cover body, the LP gas that flows downward can be discharged to the outside of the cover body, preventing the LP gas from accumulating inside the cover body.

[0011] In the cover device, at least one of the openings can be formed at a position corresponding to the valve.

[0012] According to this configuration, if an opening is formed at a position corresponding to the valve, it becomes easy to connect the valve to the piping. Also, in the unlikely event that LP gas leaks from the valve, the LP gas can be immediately discharged to the outside of the cover body.

[0013] In the above cover device, the base comprises a substrate on which the LP gas cylinder is placed, and at least one fastener which is removably fixed onto the substrate and can contact at least one of the outer peripheral surfaces of the LP gas cylinder placed on the substrate via the cover body, and the cover body can be fixed between the base and the fastener.

[0014] According to this configuration, when the LP gas cylinder is placed on the base, the fixing tool is provided, so that the LP gas cylinder can be placed along the fixing tool. Therefore, the positioning of the LP gas cylinder on the base is easy. Furthermore, if the cover body is fixed between the fixing tool and the substrate, the fixing tool can also be used as a fixing member.

[0015] In the above-mentioned cover device, the cover body can be configured in various ways, but for example, it can be configured to have a first part fixed to the base, a second part attached to the first part and covering the outer circumferential surface of the LP gas cylinder placed on the base along the circumferential direction and both ends in the circumferential direction are fixed removably, and a third part attached to the upper end of the second part and covering the upper part of the LP gas cylinder.

[0016] According to this configuration, after the LP gas cylinder is placed on the base, the second part of the cover body is wrapped around the outer peripheral surface of the LP gas cylinder, and then the third part is used to cover the upper part of the LP gas cylinder, so that the outer surface of the LP gas cylinder can be easily covered with the cover body.

[0017] The method for installing an LP gas cylinder according to the present invention comprises the steps of installing a base near a fire equipment, installing an LP gas cylinder on the base, and covering the outer surface of the LP gas cylinder installed on the base with a sheet-shaped cover body attached to the base and formed of a non-flammable material, wherein the cover body has at least one opening formed on the side facing away from the fire equipment. Effect of the Invention

[0018] According to the present invention, when isolating an LP gas cylinder from fire equipment, installation can be easily performed. [Brief description of the drawings]

[0020] Hereinafter, an embodiment of a cover device according to the present invention will be described with reference to the drawings. First, an LP gas cylinder to be covered by the cover device will be described, and then the cover device will be described.

[0021] <1.LP gas cylinder> Fig. 1 is a front view showing an example of an LP gas cylinder. As shown in the figure, this LP gas cylinder 1 is a known one, and includes a cylindrical main body 11, a cylindrical support part 12 attached to the lower end of the main body 11 and having a smaller diameter than the main body 11, and a valve 13 formed on the upper surface of the main body 11. LP gas is stored inside the main body 11, and the LP gas inside can be discharged by opening the valve 13.

[0022] <2. Covering equipment> Next, the cover device will be described. Fig. 2 is a perspective view showing an LP gas cylinder covered with the cover device. As shown in Fig. 2, this cover device includes a rectangular base 3 on which an LP gas cylinder 1 is placed, and a sheet-like cover body 4 that covers the outer surface of the LP gas cylinder 1 placed on the base 3. Each component will be described in detail below.

[0023] <2-1. Foundation> Fig. 3 is a perspective view of the base, and Fig. 4 is an exploded plan view of the base. As shown in Fig. 3, the base includes a square-shaped substrate 31, a plate-shaped first fixture 32 disposed on the substrate 31, and a pair of second fixtures 33 disposed on the substrate 31 so as to sandwich the first fixture 32. For ease of explanation, the upper, lower, right, and left sides of the substrate 31 shown in Fig. 4 will be referred to as a first side 311, a second side 312, a third side 313, and a fourth side 314.

[0024] The first fixture 32 is formed slightly shorter than the first side 311 of the substrate 31, and is disposed along the first side 311. An arc-shaped recess 321 is formed on the side of the first fixture 32 facing the second side 312. The recess 321 is formed to conform to the outer shape of the support part 12 of the LP gas cylinder 1. The first fixture 32 is detachably fixed onto the substrate 31 by screws or the like. The pair of second fixtures 33 are disposed over the entire length of the third side 313 and the fourth side 314 of the substrate 31, respectively. At this time, both ends of the first fixture 32 are sandwiched by the pair of second fixtures 33. In addition, both second fixtures 33 are also detachably fixed onto the substrate 31 by screws or the like.

[0025] As described later, the lower end of the cover body 4 is sandwiched between the substrate 31 and both fasteners 32, 33, whereby the cover body 4 and the base 3 are fixed together.

[0026] The material constituting the base 3 is not particularly limited, and it can be made of, for example, resin, metal, wood, or the like.

[0027] <2-2. Cover body> Fig. 5 is a development view showing the front surface of the cover body, and Fig. 6 is a development view showing the back surface of the cover body. The front surface here refers to the surface that faces outward when the cover body 4 is attached to the LP gas cylinder 1, and the back surface refers to the surface that faces the LP gas cylinder 1.

[0028] As shown in Figures 5 and 6, the cover body 4 comprises a rectangular first sheet 41, a rectangular second sheet 42 connected to the upper side of the first sheet 41, and a rectangular third sheet 43 connected to the lower side of the first sheet 41.

[0029] The first sheet 41 is a portion that is mainly wound around the outer circumferential surface of the main body 11 of the LP gas cylinder 1. For convenience of explanation, the upper, lower, right, and left sides of the first sheet 41 shown in FIG. 5 are referred to as the first side 411, the second side 412, the third side 413, and the fourth side 414, respectively. A first hook-and-loop fastener 51 is attached to the third side 413 on the front side of the first sheet 41 along its entire length. A second hook-and-loop fastener 52 is attached to the fourth side 414 on the back side of the first sheet 41 along its entire length. A third hook-and-loop fastener 53 is attached to the first side 411 on the front side of the first sheet 41, extending on the fourth side 414 side. The lengths of the first side 411 and the second side 412 are approximately the same as the outer circumferential length of the main body 11 of the LP gas cylinder 1. The lengths of the third side 413 and the fourth side 414 are approximately the same as the length of the main body 11 of the LP gas cylinder 1 in the up-down direction.

[0030] The second sheet 42 is narrower in width than the first sheet 41, and is connected to the third side 413 of the first side 411 of the first sheet 41. For ease of explanation, the upper side, lower side, right side, and left side of the second sheet 42 shown in FIG. 5 are referred to as the first side 421, the second side 422, the third side 423, and the fourth side 424, respectively. A fourth hook-and-loop fastener 54 is attached to the first side 421 on the front side of the second sheet 42 on the fourth side 424 side. The length of the fourth hook-and-loop fastener 54 is slightly shorter than half the length of the first side 421. A fifth hook-and-loop fastener 55 having the same length as the fourth hook-and-loop fastener 54 is attached to the first side 421 on the back side of the second sheet 42 at a position corresponding to the fourth hook-and-loop fastener 54. Furthermore, a sixth hook-and-loop fastener 56 is attached to the third side 423 side of the first side 421 on the back surface of the second sheet 42 so as to be aligned with the fifth hook-and-loop fastener 55. The sixth hook-and-loop fastener 56 is formed to be longer than the fifth hook-and-loop fastener 55, and the total length of the fifth hook-and-loop fastener 55 and the sixth hook-and-loop fastener 56 is approximately the same length as the first side 421.

[0031] The length of the third sheet 43 in the left-right direction is approximately 30 to 80% of the length of the second side 412 of the first sheet 41, and the third sheet 43 is disposed near the center of the second side 412 of the first sheet 41. The lower end of the third sheet 43 is formed into a corrugated shape, and this portion is sandwiched between the substrate 31 of the base 3 and both fasteners 32, 33.

[0032] The cover body 4 is formed from a non-flammable material, and can be formed, for example, from an inorganic fiber base fabric such as glass coated with tetrafluoroethylene resin, an inorganic fiber base fabric such as glass coated with polyvinyl chloride resin, a synthetic fiber base fabric coated with polyvinyl chloride resin, a resin-coated metal substrate, etc.

[0033] <3. Assembling the cover device and installing the LP gas cylinder> Next, the assembly of the cover device and the installation method of the LP gas cylinder will be described with reference to Figs. 7 to 14. First, the third sheet 43 of the cover body 4 is bent into an arc shape, and its lower end is sandwiched between the base plate 31 and both fasteners 32, 33 of the base 3. That is, in a state in which both fasteners 32, 33 are removed from the base plate 31, the lower end of the third sheet 43 is placed on the base plate 31 at a position where both fasteners 32, 33 are to be placed, and both fasteners 32, 33 are placed on it and screwed. At this time, the vicinity of the center in the left-right direction of the lower end of the third sheet 43 is positioned to be located near the center of the first fastener 32. In this way, the third sheet 43 is fixed to the base plate 3. Since the third sheet 43 has a shorter length in the left-right direction than the first sheet 41, when it is fixed to the base plate 3, the second side 312 side of the base plate 3 is opened as shown in Fig. 7, and the LP gas cylinder 1 can be placed on the base plate 3 from here. That is, this open portion becomes an opening 48 shown in Fig. 11 as described below. Note that Fig. 7 shows only the third sheet 43 of the cover body 3.

[0034] Next, as shown in FIG. 8, the base 3 is installed so that the LP gas cylinder is located at a position 2 m or less from the fire equipment. In this example, the fire equipment is located on the outer wall of the building, so the base 3 is placed along this wall. Next, as shown in FIG. 9, the LP gas cylinder 1 is placed on the base 3 from the second side 312 side, and the LP gas cylinder 1 is moved from between both ends of the first sheet 41 of the cover body 4 to the first fixing device 32 side. Then, when the LP gas cylinder 1 approaches the first fixing device 32, the first hook-and-loop fastener 51 and the second hook-and-loop fastener 52 at both ends of the first sheet 41 are fixed as shown in FIG. 10. In this way, the outer peripheral surface of the LP gas cylinder 1 is covered by the first sheet 41 as shown in FIG. 11. At this time, the second sheet 42 protrudes above the LP gas cylinder 1.

[0035] 11, the second sheet 42 is folded along the imaginary line L in the vertical direction passing through the boundary between the fifth hook-and-loop fastener 55 and the sixth hook-and-loop fastener 56 on the back surface of the second sheet 42, and the fifth hook-and-loop fastener 55 and the sixth hook-and-loop fastener 56 are fixed. As a result, the back surface of the second sheet 42 is in the state shown in FIG. 12. That is, since the sixth hook-and-loop fastener 56 is longer than the fifth hook-and-loop fastener 55, a part of the sixth hook-and-loop fastener 56 is exposed when the second sheet 42 is folded as described above. In addition, since the fourth hook-and-loop fastener 54 is disposed on the opposite side of the fifth hook-and-loop fastener 55, i.e., on the front surface of the second sheet 42, in the folded second sheet 42, the exposed sixth hook-and-loop fastener 56 and the fourth hook-and-loop fastener 54 are aligned in the left-right direction. In this way, the first side 421 of the second sheet 42 is folded as shown in FIG. 13.

[0036] 14, the folded second sheet 42 is folded downward, and the sixth hook-and-loop fastener 56 and the fourth hook-and-loop fastener 54 are fixed to the third hook-and-loop fastener 53 of the first sheet 41. In this manner, the attachment of the cover body 4 is completed.

[0037] An opening 40 leading to the inside of the cover body 4 is formed on the second side 312 of the base 3 in the folded second sheet 42, so that a hose or other piping can be connected to the valve 13 of the LP gas cylinder 1 from here. As shown in FIG. 15, the length of the third sheet 43 in the left-right direction is shorter than the length of the first sheet 41 in the left-right direction, so that an opening 48 is formed on the side of the lower end of the cover body 4 where the third sheet 43 is not arranged. Since this opening 48 is formed on the opposite side to the fire equipment, even if LP gas leaks from a part of the LP gas cylinder 1 such as the valve 13, the LP gas flows downward and is discharged to the outside from the opening 48 on the opposite side to the fire equipment. Therefore, it is possible to prevent the LP gas from flowing toward the fire equipment.

[0038] <4. Features> The cover device configured as above has the following advantages. (1) Since the LP gas cylinder 1 is covered with the cover body 4 made of a non-flammable material and configured to be isolated from fire equipment, unlike the case where a non-flammable partition is disposed between the fire equipment and the LP gas cylinder 1, the space required for installing a non-flammable partition is not required, and the LP gas cylinder 1 can be easily isolated from the fire equipment. Also, since isolation is possible simply by covering the LP gas cylinder 1 with the sheet-like cover body 4, installation is also easy. Furthermore, since the cover body 4 has an opening 48 formed on the side opposite the fire equipment, even if LP gas leaks from the LP gas cylinder, it is possible to prevent it from flowing toward the fire equipment.

[0039] (2) This cover device is provided with a base 3 on which the LP gas cylinder 1 is placed, so that the LP gas cylinder 1 can be stably placed. In addition, the cover body 4 is attached to the base 3 and formed integrally therewith, so that the cover device can be easily handled. The base 3 is provided with fasteners 32, 33 that can be contacted via the cover body 4 on the outer periphery of the LP gas cylinder 1, so that these fasteners 32, 33 can be used for positioning when placing the LP gas cylinder 1 on the base 3. Furthermore, in addition to positioning, these fasteners 32, 33 can also be used to fix the cover body 4 as described above.

[0040] (3) Since LP gas is heavier than air, if it leaks from the LP gas cylinder 1, it will flow downward. In this embodiment, the opening 48 is formed at the lower end of the cover body 4, so that the LP gas that flows downward can be discharged to the outside of the cover body 4, and the LP gas can be prevented from accumulating inside the cover body 4.

[0041] (4) Since the opening 40 is also formed in the upper part of the cover body 4, it is easy to connect the valve 13 to the piping through this opening 40. In addition, in the unlikely event that LP gas leaks from the valve 13, the LP gas can be immediately discharged to the outside of the cover body 4.

[0042] <5. Modifications> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. In addition, the following modified examples can be appropriately combined.

[0043] <5-1> In the above embodiment, the LP gas cylinder 1 and the cover device are arranged along the wall on which the fire equipment is arranged, but this is not limited thereto, and for example, as shown in Fig. 16, the LP gas cylinder 1 and the cover device can be arranged along the wall facing the fire equipment. In this case, as in the above embodiment, the LP gas cylinder 1 is arranged at a position 2 m or less from the fire equipment. Also, in the above embodiment, the cover body 4 is attached to the base 3, and then the base 3 is installed near the fire equipment, but the cover body 4 may be attached to the base 3 after the base 3 is installed near the fire equipment.

[0044] <5-2> In the above embodiment, one LP gas cylinder 1 is accommodated in the cover device, but two or more LP gas cylinders 1 may be accommodated. For example, as shown in Fig. 17, the base 3 may be formed to a size that allows two LP gas cylinders 1 to be installed, and the cover body 4 may be formed to accommodate two LP gas cylinders 1. To accommodate two or more LP gas cylinders 1, for example, the length of the first to third sheets 41 to 43 in the left-right direction may be increased.

[0045] <5-3> The configuration of the cover body 4 is not particularly limited, and the shape is not particularly limited as long as it is configured to cover the outer surface of the LP gas cylinder 1 and has at least one opening for discharging the LP gas on the side opposite to the fire equipment. Therefore, the position, shape, and number of the openings are not particularly limited. In the above embodiment, the hook-and-loop fasteners 51 to 56 are used to attach the cover body 4 to the outer surface of the LP gas cylinder 1, but the present invention is not limited to this, and any other detachable fixing means such as a button or a clip can be used as appropriate.

[0046] <5-4> The configuration of the base 3 is not particularly limited, and its shape and material are not particularly limited as long as the LP gas cylinder 1 can be placed thereon and the cover body 4 can be fixed thereto. Therefore, it is sufficient if at least the LP gas cylinder 1 can be placed thereon and the cover body 4 can be fixed thereto. Also, the base 3 is not necessarily required, and the cover device can be configured with only the cover body 4. In this case, it is necessary that the cover body 4 covers the LP gas cylinder 1 up to its bottom end. [Explanation of symbols]
