Piping cover assembly set

Technical field

TECHNICAL FIELD [0001] The present invention relates to a piping cover assembly set, and more specifically, a necessary portion of a piping cover force S. A piping cover assembly that can easily and quickly constitute a piping cover regardless of its complicated shape. Regarding the set.

Background art

[0002] Conventionally, in an existing ground-open system piping facility in which straight pipes, T-shaped pipes, elbow pipes, L-shaped pipes or the like are connected via connecting members such as joints, each pipe or connecting member is connected. By wrapping the outer force with a resin sheet and tightening and sealing it, it is possible to temporarily prevent leakage of fluid such as liquid and gas flowing inside the piping, and to prevent surrounding pollution and environmental destruction in advance. A piping cover is known (Patent Document 1). The piping power bar can be seen through the inside, so that maintenance work on the piping line can be easily performed from the outside visually.

[0003] Generally, there are many types of combinations of piping and connecting members of piping equipment, each having a different shape. For this reason, the piping cover must be created in a form corresponding to each of these types of shapes.

[0004] However, there are an enormous number of parts that require piping covers in piping facilities, and there are many types of shapes, so the piping cover can be used according to the shape of the necessary parts. It is a waste of time and labor to create each one.

[0005] For example, in a plant facility where a large amount of piping is installed, after the plant facility is completed, the shape of each piping and the shape of each connecting member are observed, and piping covers are designed according to these various shapes. However, piping covers corresponding to each shape must be created one by one for the first time to cut out the resin sheet, which requires a lot of time. For this reason, in plant facilities where fluid leakage is considered dangerous, even if the plant facilities are completed, they cannot be operated until the piping cover is installed, and the start-up time of the plant facilities is Will be greatly delayed by the construction period of the cover. [0006] In addition, even in plant facilities that are currently in operation, if a fluid leak occurs due to problems such as aging, and a piping cover is required, the plant equipment must be installed until the piping cover is installed. The operation must be stopped. However, stopping the operation of the plant equipment, even if temporarily, involves great damage, so it is desirable to install the piping cover as soon as possible and to resume the operation of the plant equipment as soon as possible.

[0007] Furthermore, in the case where the operation of the plant facility cannot be stopped immediately even if the fluid leaks, there is a concern about the surrounding contamination due to the leaked fluid. Even in such a case, it is necessary to attach a piping cover as soon as possible to stop the surrounding contamination due to fluid leakage at an early stage.

[0008] On the other hand, in order to apply the piping cover easily and quickly to the necessary part without starting the cutting work force of the resin sheet according to the shape of the necessary part, a piping cover prepared in advance is used. It is also conceivable to select and use according to the shape of the necessary part. However, it is practically impossible to prepare and prepare a piping cover for each shape of the necessary part.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a piping cover assembly set according to the present invention. The piping cover single-thread upright set includes a conical element 1, a cylindrical element 2, a curved tubular element 3, and a hook-shaped element 4.

[0022] The piping cover is a connecting part of piping and piping, connecting parts of piping and piping parts, or the connecting parts of chemical liquid, oil, pure water, and other fluids on the ground, underground, or under the floor, and behind the ceiling. A cover that wraps from the outside, including piping and piping parts that exist in the site, and is formed using a resinous sheet. Piping parts include flanges, elbows, cheeses, expansion joints, various valves, sockets, reducers, pressure gauges, and so on.

[0023] The connecting portion has various shapes depending on the combination of each pipe and each piping component, but the present invention wraps the connecting portions having such various shapes. The piping cover should be prepared easily and quickly by selecting the above-mentioned four types of elements 1, 2, 3, and 4 according to the shape of the connecting part and combining them.

[0024] Therefore, it is not necessary to perform the work of molding and cutting out the resinous sheet on the piping cover each time according to the various shapes of the connecting portions, so the piping covers according to the shapes of the various connecting portions. Can be created easily and quickly.

[0025] The resin-made sheet for constituting each element 1, 2, 3 and 4 of the assembly set of the piping cover according to the present invention is transparent or translucent and may be colored.

[0026] The material of the resinous resin sheet is not particularly limited, and it has weather resistance, chemical resistance, and oil resistance!

[0027] The thickness of the resin sheet constituting each of the elements 1, 2, 3 and 4 is preferably in the range of 0.15 mm to 3. Omm, more preferably 0.15 mn! ~ 2. Omm.

[0028] Next, each of the elements 1, 2, 3, and 4 constituting the assembly set of the piping cover according to the present invention

4 will be described.

[0029] Fig. 2 (a) is a development view showing the conical elements, and (b) is a diagram showing a state in which the conical elements are formed in a conical shape.

[0030] The conical element 1 is mainly used to seal the inside of the pipe cover by tightening the outer surface of the pipe with a fastening member such as a tape band when the pipe cover is configured. This is the element that forms the sealing part, and the large arc end 11 that forms a large arc, the small arc end 12 that forms a small arc, and the large arc end 11 and the small arc end by a resin sheet. It is formed in a substantially fan shape having two end sides 13 and 14 that are linearly connected to 12.

[0031] In order to form the conical element 1 into a conical shape, as shown by the arrows in FIG. 2 (a), the edges 13 and 14 are rounded so that they are close to each other, and are shown in FIG. 2 (b). As shown in FIG.

[0032] The conical element 1 formed in a conical shape has a large circular arc end 11 formed in a substantially circular shape, thereby having a large-diameter opening 1A and a small circular arc end 12 formed in a substantially circular shape. Thus, it has a small-diameter opening 1B.

[0033] The large-diameter opening 1A matches the openings of other elements to be described later and welds them together. The small-diameter opening 1B functions as a pipe insertion port, which will be described later. This small-diameter opening 1B side serves as a sealing portion for sealing the inside of the piping cover.

[0034] When the piping cover is configured, the conical element 1 is closed so that it can be opened and closed by connecting the edges 13 and 14 adjacent to each other by an engagement element described later. Accordingly, the end sides 13 and 14 become the attachment portion 10 of the engaging element.

FIG. 3 (a) is a development view showing a cylindrical element, and FIG. 3 (b) is a diagram showing a state in which the cylindrical element is formed into a cylindrical shape.

[0036] The cylindrical element 2 is an element mainly for wrapping a flange portion for connecting pipes to each other, and is formed into a rectangular shape having four linear edges 21, 22, 23, 24 by a resin sheet. Is formed.

[0037] In order to form the cylindrical element 2 in a cylindrical shape, as shown by the arrows in Fig. 3 (a), the two opposing edges 23 and 24 are rounded so as to be close to each other, and Fig. 3 (b ) To form a cylindrical shape

[0038] In the cylindrical element 2 formed in a cylindrical shape, two opposed end sides 21 and 22 respectively connected to both ends of two end sides 23 and 24 close to each other are formed in a substantially circular shape. Thus, openings 2A and 2B are provided at both ends, respectively.

[0039] Each opening 2A, 2B is formed such that the length of each end side 21, 22 is the same as the length of the large arc end side 11 of the above-mentioned cone-shaped element 1, whereby the large size of the cone-shaped element 1 is obtained. It is formed so as to have the same diameter as the opening 1A having a diameter, and thereby functions as a welding portion for matching the large-diameter opening 1A of the conical element 1 and welding them together. At the same time, the two cylindrical elements 2 are matched with the openings 2A or 2B and welded to form a long cylindrical element 2 as a welded part, or as described below. It also functions as a welded part to match the opening of the element and weld them together.

[0040] When the piping cover is configured, the cylindrical element 2 is closed so that it can be opened and closed by connecting the end sides 23 and 24 adjacent to each other by an engagement element described later. Accordingly, the end sides 23 and 24 serve as attachment portions 20 for the engagement elements.

FIG. 4 (a) is a development view showing the curved tubular element, FIG. 4 (b) is a diagram showing a state in which the curved tubular element is formed in a cylindrical shape, and FIG. 5 is a diagram showing components of the curved tubular element. [0042] The curved tubular element 3 is an element mainly for wrapping the connecting portion using the elbow pipe in the piping facility, and the doughnut-shaped sheet is substantially fan-shaped as shown in FIG. Make a curved tube shaped like a cut out!

[0043] The curved tubular element 3 is symmetrical with respect to the arc edge 31 and linear ends 32, 33 and edges 34, 35 are connected to one end of the arc edge 31. As the distance from the end 31 increases, the other end of the end 32 and the other end of the end 34 and the other end of the end 33 and the other end of the end 35 are linear ends. The shape is connected by sides 36 and 37.

[0044] As shown in Fig. 5, the curved tubular element 3 uses two substantially fan-shaped sheets 3a and 3b, and the arc end sides 31a and 31b are bonded or welded together to form one arc end side. If 31 is formed, it is preferable because it can be easily cut out from a planar resin sheet.

[0045] In order to form such a curved tubular element 3 in a cylindrical shape as shown in Fig. 4 (b), as shown by the arrow shown in Fig. 4 (a), an end side 36 and an end side 37 are formed. The side 32 and the side 33, and the side 34 and the side 35 are spread out from each other.

[0046] The curved tubular element 3 formed into a cylindrical shape has openings 3A and 3B at both ends by forming the widened end sides 32 and 33 and end sides 34 and 35 into a substantially circular shape, respectively. . Each opening 3A, 3B is arranged in a positional relationship such that the central axis of one opening 3A and the central axis of the other opening 3B intersect.

[0047] Each of the openings 3A and 3B has a total length of the end sides 32 and 33, and a total length of the end sides 34 and 35, and the large arc end side 11 of the conical element 1 11 Is formed so as to have the same diameter as the large-diameter opening 1A of the conical element 1. As a result, each opening 3A, 3B functions as a welding portion for matching the large-diameter opening 1A of the conical element 1 and welding them together. At the same time, they are welded together so as to match the openings 3A or 3B of the other curved tubular element 3, so that they are welded in the case of forming a continuous curved tubular element 3 or other later described. It also functions as a welded part to match the element opening and weld them together.

[0048] When the piping cover is configured, the curved tubular element 3 has the ends 36 and 37 adjacent to each other. Are closed so as to be openable and closable by being connected by an engagement element described later. Accordingly, the end sides 36 and 37 serve as attachment portions 30 for the engaging elements.

[0049] It should be noted that the curved tubular element 3 can be provided with different positions of the attachment portion 30. For example, instead of adhering the arc edges 31a, 31b of the resin sheets 3a, 3b shown in FIG. 5, by adhering the edges 36, 37 to each other, as shown in FIG. The ends 31a and 31b may be the attachment portion 30.

[0050] There are different types of elbow pipes with different bending angles, such as 45 ° and 90 °, but the curved tubular element 3 is made of a resin-made sheet, so it can be bent freely according to the bending angle of the applied elbow pipe. It is possible to use it. Therefore, it can also be used when one type of curved tubular element 3 surrounds a plurality of types of elbow tubes having different bending angles.

FIG. 7 (a) is a development view showing a T-shaped element, and FIG. 7 (b) is a diagram showing a state in which the T-shaped element is formed in a cylindrical shape.

[0052] The T-shaped element 4 is an element for wrapping a connecting portion where the pipes cross in a T-shape mainly in the piping facility. The T-shaped element 4 is opposed to the resin as shown in FIG. The longest side 41, 42 having the longest length, and the middle end, facing the large end 41, 42 that is shorter than the large end 41, 42, in a direction substantially perpendicular to the long end 41, 42 43, 44, and the large end side 41, which is shorter than the middle end side 43, 44, and the small end side 45, 46 connecting the middle end side 43, 44, the large end side 42, and the middle end side 43 , 44 are formed in an octagonal shape having small end sides 47, 48 connecting them.

[0053] In order to form such a T-shaped element 4 in a cylindrical shape as shown in Fig. 7 (b), as shown by the arrows shown in Fig. 7 (a), a small end side 45 and a small end side 46 are formed. And round the small edge 47 and the small edge 48 close to each other.

[0054] The T-shaped element 4 formed in a cylindrical shape has two opening portions (first opening portions) 4A arranged opposite to each other by forming the large end sides 41 and 42 in a substantially circular shape. An opening (second opening) 4B, and the middle end side 43 and the middle end side 44 are combined to form a substantially circular shape, thereby forming one opening (third opening). ) Has 4C. The opening 4C is disposed so as to open in a direction substantially orthogonal to a central axis connecting the centers of the openings 4A and 4B. [0055] The openings 4A and 4B are formed to have the same length as the length of the large arc edge 11 of the cone-shaped element 1 by the length force of the large edges 41 and 42. It has the same diameter as the large-diameter opening 1A. In addition, the opening 4C is formed so that the length force of each of the middle end sides 43 and 44 is half the length of each of the large end sides 41 and 42, so that the two middle end sides 43 and 44 are combined. Is the same length as the length 11 of the large arc edge 11 of the cone-shaped element 1 and has the same diameter as the large-diameter opening 1A of the cone-shaped element 1. As a result, these openings 4A, 4B, and 4C also function as welds for matching the large-diameter openings 1A of the conical element 1 and welding them together. At the same time, the two T-shaped elements 4 are welded together by matching the openings 4A, 4B, or 4C with the openings 4A, 4B, or 4C. Furthermore, it also functions as a welded part for welding both of them together with the opening of other elements.

[0056] When configuring the piping cover, the T-shaped element 4 can be opened and closed by connecting the small end sides 45 and 46 close to each other and the small end sides 47 and 48 by engagement elements described later. Closed. Accordingly, the small end sides 45 and 46 and the small end sides 47 and 48 serve as attachment hooks 40 and 40 for the engagement element.

[0057] The piping cover according to the present invention has a cone-shaped element 1, a cylindrical element 2, a curved tubular element 3, and a T-shaped element as described above, depending on the shape of the part where the piping cover is required in the piping facility. As for the medium force of the assembly set of the piping cover having the element 4, at least two kinds of elements are appropriately selected and combined, and the openings of the respective elements are welded together to easily and quickly form the piping cover of a desired form. Can be formed.

[0058] For example, FIG. 8 shows an application example of the piping cover C1 in which two types of elements are combined in a form suitable for the joint portion between the straight pipes Pl and PI. Reference numeral F denotes a flange provided at each end of the straight pipes Pl and PI.

[0059] As shown in Fig. 9, this piping cover C1 is composed of two conical elements 1 and one cylindrical element 2, and the attachment parts 10 and 10 of the conical element 1 and the cylindrical element 1 After aligning the mounting part 20 of 2 with the mounting part 20 so as to be substantially straight, welding the large-diameter opening 1A of the conical element 1 and both openings 2A and 2B of the cylindrical element 2, each attachment The fasteners 5 and 5 that are engaging elements are welded over the portions 10, 10, and 20. Fasteners 5 and 5 are all It is cut according to the length of the mounting parts 10, 10, 20 and opened and closed by sliding the slider 6.

[0060] This pipe cover C1 is flanged as shown in FIG. After wrapping the straight pipe Pl, PI containing F, if necessary, the small diameter opening 1B of each conical element 1, 1 on both sides, 1B, IB side, appropriate packing, adhesive tape, tightening band Tighten directly using a tightening member 7 that has equal force, or via a packing or spacer formed of the same material as the resin sheet.

[0061] It should be noted that the slider 6 after the fasteners 5 and 5 are closed does not interfere with the tightening of the conical elements 1 and 1 if they are removed from the fasteners 5 and 5. Fasteners 5 and 5 are provided with both ends at the outer sides of the small-diameter openings 1B and IB of the conical elements 1 and 1, respectively, in order to improve the workability when the slider 1 is remounted. It is preferable to protrude about 20 mm.

[0062] The piping cover C1 using the two types of elements, the conical element 1 and the cylindrical element 2, is made of a resin sheet with respect to a portion where a pipe having a straight pipe force is connected via a flange. Cut-out work ability Can be formed very easily and quickly as needed.

[0063] Similarly, by using two types of conical element 1 and curved tubular element 3 and two types of conical element 1 and T-shaped element 4 according to the shape of the connecting portion, the piping cover can be provided. It can be formed easily and quickly.

[0064] FIG. 10 is an application example of the piping cover C2 in which two elements are combined in a form suitable for a portion where two straight pipes Pl and PI are joined using an elbow pipe P2. In this case, instead of the cylindrical element 2 shown in FIG. 9, the curved tubular element 3 shown in FIG. 4 is used, and the openings 1A and 1A of each conical element 1 and the openings 3A of the curved tubular element 3 3B is welded, and each mounting portion 10, 10, 30 is formed to be openable and closable using a fastener (not shown in FIG. 10).

[0065] The piping cover C2 using the two elements of the conical element 1 and the curved tubular element 3 is used to cut out a resin sheet from a portion where the pipes are connected to each other using an elbow pipe. It can be formed very simply and quickly as needed.

[0066] Fig. 11 shows an application example of the piping cover C3 in which two types of elements are combined in a form that fits the part where three straight pipes Pl, Pl, PI are connected using a T-shaped pipe P3. is there. In this case, Using the T-shaped element 4 shown in Fig. 7, the opening 1A of the conical element 1 is welded to each of the openings 4A, 4B, and 4C. The conical element 1 to be welded to the third opening 4C of the T-shaped element 4 is cut in one place over the openings 1A and IB by using a cutter or the like, so that the T-shaped element 1 In order to correspond to the two mounting parts 40 and 40 in Fig. 4, another mounting part 40 is formed, and each of the mounting parts 10, 10, 40 and 40 is fastened (as shown in FIG. 11). (Not shown) so that it can be opened and closed.

[0067] The piping cover C3 using the two elements of the conical element 1 and the T-shaped element 4 is connected to the portion where the straight pipes are connected so as to cross each other in a T-shape. Therefore, it can be formed very easily and quickly as much as it is necessary to start the cutting work of the resin sheet.

[0068] The conical element 1 is not necessarily an element that must be provided at the end of the piping cover. For example, it is not necessary to use the conical element 1 at the part where the flange at one end of the straight pipe is closed. For example, one opening 2A (or 2B) of the cylindrical element 2 is appropriately used with a resin sheet. Just plug it in.

[0069] Further, according to the assembly set of the piping cover according to the present invention, the piping cover can be formed by combining not only the above two types of elements but also a combination of three or more types. In this case, it is possible to combine the cylindrical element 2, the curved tubular element 3, and the T-shaped element 4 with each other.

[0070] For example, FIG. 12 shows that two conical elements 1, one cylindrical element 2 and one curved tubular element 3

This is an application example of piping cover C4 using three types of elements.

[0071] This piping cover C4 includes two straight pipes Pl and PI connected to each other and two straight pipes PI and P.

When it is necessary to surround 1 to include the entire part connected via elbow pipe P2.

It can be formed very easily and quickly as necessary.

[0072] Fig. 13 shows the case where all of the four types of elements are used: three conical elements 1, one cylindrical element 2, two curved tubular elements 3, and one T-shaped element. This is an application example of piping cover C5 using 4.

[0073] As shown in Fig. 13, this piping cover C5 has two straight pipes Pl, PI and two straight pipes Pl, PI connected to the part where three straight pipes Pl, Pl, PI and T-shaped pipe P3 are connected. Connected via elbow pipes P2 and P2. When enclosing it so as to include all the connecting parts with complicated shapes that connect straight pipe PI, elbow pipe P2 and T-shaped pipe P3, etc., it is necessary to start cutting out the resin sheet. The cover for piping can be formed easily and quickly, and the effects according to the present invention can be exhibited particularly remarkably.

[0074] Further, even if the shape of the connecting portion other than the shape of the connecting portion disclosed above is selected, the shape is selected from four types: conical element 1, cylindrical element 2, curved tubular element 3, and T-shaped element 4. By appropriately combining two or more types and welding the openings together, a piping cover with a configuration that is also suitable for connecting parts of more complex shaped pipes can be cut out. It will be readily understood that it can be formed as simply and quickly as needed. Of course, the number of each element selected from the four types of elements 1, 2, 3, and 4 can be appropriately changed according to the shape of the connecting portion.

[0075] In general, since pipes and connecting members have various standardized sizes, the above four types of elements are also formed in a plurality of types according to the various sizes, and each size can be changed. It is preferable to set the above four elements together.

[0076] Further, the engagement element is not limited to the type in which the fasteners 5 and 5 disclosed above are opened and closed by the sliding operation of the slider 6, but the attachment portions 10, 20, 30, 40 of each element There is no particular limitation as long as it can be configured to be openable and closable.

For example, as another example of the engaging element, a hook-and-loop fastener 8 can be used as shown in FIG. FIG. 14 shows a cross section when the hook-and-loop fastener 8 is used for the cylindrical element 2. One of the hook-and-loop fasteners 8 is attached to the inside of one attachment part 20 of the cylindrical element 2 and the other of the hook-and-loop fasteners 8 is attached to the outside of the other attachment part 20. By engaging, the cylindrical element 2 is closed in a bag shape.

The hook-and-loop fastener 8 can be similarly applied to the other elements 1, 3, and 4. Therefore, by providing the hook-and-loop fastener 8 over two or more elements, the piping cover formed by these elements can be closed so as to be opened and closed.

Thus, according to the piping cover assembly set according to the present invention, a predetermined shape of the conical element 1, the cylindrical element 2, the curved tubular element 3, and the T-shaped element 4 is selected. Enclose various types of connecting parts by appropriately combining at least two types of elements The piping cover that can be formed can be formed easily and quickly without the need to start the cutting work force of the resin sheet. Accordingly, for example, even in the case of plant equipment, it is possible to quickly complete the creation and installation of the piping cover, and the time to operation can be greatly shortened.

In addition, the welded parts where the elements 1, 2, 3 and 4 are welded together are because each of the openings 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B and 4C is substantially circular. Since it is only formed in a single line, welding work that does not require welding in a complex shape is extremely easy. For this reason, each element 1, 2, 3 and 4 have good sealing properties, and the sealing state can be ensured. Therefore, it is possible to assemble a piping cover without fear of fluid leakage from the welded portion.
