Description

[Technical field]

[0001] The present invention relates to a curing capsule for preventing powder or granular material from falling downward along a chain stretched in a substantially vertical direction, and a curing method using the same. [Background technology]

[0002] For repair and inspection work on the painting of elevated structures such as viaducts, a suspended scaffolding suspended by a hoisting chain is often used. This suspended scaffolding is installed to the side or below the elevated structure.

[0003] Patent documents 1 and 2 describe a suspended scaffolding in which a scaffolding board has mounting holes that communicate from above and below, and a hanging bracket protrudes from the underside of the board to the top side through the mounting holes and connects to a hook at the bottom end of a hanging chain, thereby suspending the scaffolding board from an elevated structure.

[0004] Patent Document 3 also describes a suspended scaffolding 100 in which a scaffolding board 101 has mounting holes 101a that communicate vertically as shown in Figure 11, and a suspension chain 102 is passed through the mounting holes 101a and wound in an approximately U-shape around a single pipe 103 arranged on the underside of the scaffolding board 101, thereby suspending the scaffolding board 101 from an elevated structure.

[0005] In high-altitude work such as painting repair and inspection work on this type of suspended scaffolding, the existing paint is peeled off by a blasting method (using blast abrasives with a diameter of about 0.3 to 1.2 mm), which generates powder such as blast abrasives and peeled paint chips. The powder falls down the suspended scaffolding through the mounting holes of the scaffolding boards along the surface of the suspension chain.

[0006] In order to prevent such powder from falling, in the curing work, as shown in Fig. 12, a method is often used in which flexible resin 104 such as silicone or urethane is filled in the gap between the hanging chain 102 and the curing sheet 105 that is placed over the scaffolding board 101 and the curing tape 106 that secures it, and in the gap between the mounting hole 101a of the scaffolding board 101 and the hanging chain 102. The waterproof structure described in Patent Document 3 also employs a method of filling with flexible resin. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent Publication No. 2016-89522 [Patent Document 2] Patent Publication No. 2017-128876 [Patent Document 3] Patent Publication 2019-120056 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in order to ensure safety when working at height, the scaffolding boards of a suspended scaffold are supported by a large number of suspension chains placed at predetermined intervals, so flexible resin must be filled into the installation points of each suspension chain, which poses the problem that the protective work is very complicated and requires a great deal of time and effort.

[0009] In addition, since the hanging chains and scaffolding planks that constitute the suspended scaffolding are reused, the flexible resin must be peeled off from the hanging chains and scaffolding planks at each of the many locations filled with the flexible resin after use, which is very cumbersome and requires a lot of time and effort. Although it is possible to use a solvent to make the flexible resin easier to peel off, there is also the problem that only a weak solvent can be used because the use of a strong solvent may damage the hanging chains and scaffolding planks and reduce their strength.

[0010] Furthermore, the method of filling with flexible resin has the problem that vibrations caused by working at height can cause gaps to appear between the flexible resin and the surface of the hanging chain or scaffolding board, or cracks to appear in the flexible resin, causing the powder to fall through the gaps and cracks to the bottom of the suspended scaffolding. [Means for solving the problem]

[0011] In order to solve the above problems, the first invention of the present invention is a capsule for health care, a shell formed in a substantially cylindrical shape that surrounds substantially the entire circumference of the protected portion of the chain stretched in a substantially vertical direction and that is fitted onto the protected portion of the chain; a powder / granular material drop prevention member disposed inside the shell so as to prevent the powder / granular material from dropping downward through the inside of the shell, The shell body is composed of a plurality of shell pieces that are divided into at least two in the circumferential direction of the peripheral wall surrounding the chain, and at least two adjacent shell pieces are connected to each other by a hinge portion so that they can be opened and closed.

[0012] The powder / granular material drop prevention material is not particularly limited, but examples thereof include sponge, cotton (soft fiber mass), fur, feathers, woven fabric, nonwoven fabric, etc. When a sponge is used as the powder / granular material drop prevention material, a space may be provided in the vertical middle of the sponge, and the space may be filled with gel as the powder / granular material drop prevention material, thereby improving the drop prevention effect of the powder / granular material.

[0013] The hinge portion is not particularly limited, but examples include a hinge structure in which a member bends up and down or left and right around a rotation axis, and a flexible hinge structure using a thin-walled connecting portion that elastically connects solid portions to each other.

[0014] According to this configuration, the shell having the powder / granular material fall prevention material disposed therein is fitted to the protected portion of the chain, so that the powder / granular material can be prevented from falling downward along the surface of the chain. The shell is divided into at least two shell pieces, and at least two adjacent shell pieces are connected to each other by a hinge portion so as to be openable and closable, so that the shell can be easily and quickly fitted to and removed from the protected portion of the chain. Furthermore, since the protective capsule prevents the powder / granular material from falling downward along the surface of the chain, the protective capsule can be easily protected, and therefore the protective capsule can be easily removed.

[0015] The second invention is a capsule for health care, which is the first invention, In the embodiment shown, the powder / granular material drop prevention material is disposed on the inner surface of each of the shell pieces.

[0016] According to this configuration, when the shell pieces are arranged so as to surround the periphery of the chain, the powder / granular material fall prevention material arranged on the inner surface of each shell piece can be arranged so as to surround the periphery of the chain.

[0017] The third invention is a capsule for health care according to the first or second invention, An embodiment is illustrated in which the shell pieces, which are opened and closed by the hinge portion, are provided with a locking portion that can lock the shell pieces in a closed state and can release the lock.

[0018] According to this configuration, the locking portion can easily maintain the state in which the chain is attached to the protected portion and release the attached state.

[0019] The fourth invention is a capsule for curing, which is any one of the first to third inventions, The shell has a protruding portion protruding toward an outer periphery of the shell at least at a lower end of the upper and lower ends, The projecting portion is in contact with a substantially horizontal surface, so that the shell is configured to maintain substantially the same posture as when it is fitted onto the cured portion of the chain.

[0020] According to this configuration, the protruding portion maintains the shell in substantially the same position as when it is applied to the cured portion of the chain with respect to a substantially horizontal plane, so that the shell can be easily applied when the cured portion of the chain is immediately above a substantially horizontal plane. Also, when a curing sheet is fixed to the shell with curing tape, the protruding portion can be used as a locking portion. Furthermore, by providing the protruding portion, the rigidity of the shell can be improved.

[0021] The fifth invention is a capsule for curing, which is any of the first to fourth inventions, An embodiment in which a magnet is provided for attracting the magnetic material contained in the powder or granule will be exemplified.

[0022] The magnet is not particularly limited, but examples thereof include permanent magnets, alloy magnets, ferrite magnets (including rubber magnets made of powder kneaded into rubber and plastic magnets kneaded into plastic), rare earth magnets, electromagnets, etc. The location where the magnet is disposed is not particularly limited, but examples thereof include disposing the magnet at the top and bottom ends of the shell, or disposing the magnet inside the shell.

[0023] According to this configuration, the magnet can improve the effect of preventing the powder or granular material from falling, particularly when a magnetic material is used as the blast abrasive.

[0024] The curing method using the curing capsule of the sixth invention is as follows: A curing method using the curing capsule according to any one of claims 1 to 5, Attaching the protective capsule to the protective portion of the chain; and curing the shell of the curing capsule, thereby curing the area to be cured via the curing capsule.

[0025] According to this method, it is possible to obtain the same effect as that of the above-mentioned curing capsule. Effect of the Invention

[0026] The curing capsule and the curing method using the same according to the present invention have the excellent effect of enabling simple and quick curing of a chain stretched in a substantially vertical direction against the influence of powder and granular material.

[0028] A curing capsule 1 according to a first embodiment of the present invention will be described below together with a curing method using the capsule with reference to Figures 1 to 7. As shown in Figures 5 and 6, the curing capsule 1 of the present invention is attached to a curing location of a chain 10 stretched substantially in the vertical direction, and includes a shell 2 and a powder / granular material drop prevention material 3.

[0029] As shown in Figs. 1 to 6, the shell 2 is fitted to the area of ​​the chain 10 to be protected, and is formed in a generally cylindrical shape extending in the vertical direction so as to surround the generally entire circumference of the area to be protected, and is composed of two shell pieces 4 and 5. The shell 2 of this example is configured to be symmetrical from top to bottom so that it can be used regardless of the top or bottom, and has a peripheral wall portion 2a formed in a generally cylindrical shape with a generally rounded rectangular cross section, and a generally annular end wall portion 2b extending inwardly of the cylindrical shape is integrally formed with each of the upper and lower ends of the peripheral wall portion 2a. In addition, the shell 2 is provided with protruding portions 2c protruding from the long side of the generally rounded rectangular shape toward the outer periphery of the shell 2 at each of the upper and lower ends of the peripheral wall portion 2a, and is configured so that the shell 2 maintains a posture generally similar to that when it is fitted to the area to be protected of the chain 10 by grounding the protruding portions 2c against a generally horizontal plane.

[0030] The end wall 2b is provided with a through hole 6 that communicates the inside and outside of the shell 2. The through hole 6 is formed in an elongated hole extending in the direction of the long side of the approximately rounded rectangle, and circular expanded diameter parts 6a, 6b formed with a diameter larger than the width of the elongated hole are provided at both ends in the longitudinal direction of the elongated hole. One expanded diameter part 6a is formed with a relatively larger diameter than the other expanded diameter part. When a single thick chain 10 is cured, the chain 10 is arranged in the large-diameter expanded diameter part 6a as shown in FIG. 5. When two or four thin chains 10 are cured together, all of the multiple chains 10 are arranged in the through hole 6 as shown in FIG. 6. As an example of the thick chain 10, an embodiment in which each link 10a (metal ring) constituting the thick chain 10 is formed with a thickness of 1.0 cm, a width of 3.0 cm, and a height of 5.0 cm is shown. As an example of a thin chain 10, each of the links 10a (metallic rings) that make it up is formed to have a thickness of 0.5 cm, a width of 2.0 cm, and a height of 5.0 cm.

[0031] The two shell pieces 4, 5 are formed by splitting the shell 2 at approximately the center of both short sides of the rounded rectangle in plan view. The joint between the two shell pieces 4, 5 adopts a nested structure with one concave and the other convex, and the interlocking concaves and convexes prevent gaps from occurring at the joint. One of the two joints between the shell pieces 4, 5 on the peripheral wall 2a of the shell 2 is rotatably connected by three hinge parts 7 arranged in a vertical row, and the other joint can be locked or unlocked by two lock parts 8 arranged in a vertical row.

[0032] 4, the hinge portion 7 includes a vertically extending shaft 7a provided on one shell piece, and a rotating portion 7b provided on the other shell piece and engaged with the shaft 7a so as to be rotatable relative to the shaft 7a. In this example, the shafts 7a and the rotating portions 7b of the three hinge portions 7 are configured to be engageable with and detachable from one another, allowing the shell 2 to be disassembled and assembled into the two shell pieces 4, 5.

[0033] The locking portion 8 is provided with an engaging portion 8a and an engaged portion 8b which are formed so as to be engageable with and detachable from each other at the joint portion on the other side.

[0034] The material of the shell 2 is preferably resistant to chemical substances such as solvents that may adhere to the capsule for curing 1 of the present invention in the environment in which it is used, and is not particularly limited, but examples include polycarbonate (PC), acrylonitrile-styrene-acrylic acid ester (ASA), polypropylene (PP), etc. When used in cold regions, the material of the shell 2 may be an elastic rubber-based resin.

[0035] The powder / granular material drop prevention material 3 is disposed inside the shell 2 so as to prevent the powder / granular material from dropping downward through the inside of the shell 2. In this example, the powder / granular material drop prevention material 3 is made of sponge and is disposed on the inner surface of each of the shell pieces 4 and 5 as shown by the two-dot chain line in FIG.

[0036] The sponge in this example is formed in a rectangular parallelepiped shape as shown in FIG. 2, and is formed to have a volume larger than the internal volume of the shell body 2 in order to improve the adhesion between the surface of the chain 10 and the surface of the sponge when the shell body 2 is closed. Although not particularly limited, the thickness of the sponge disposed inside the shell pieces 4, 5 is formed to be 1.0 cm or more thicker than the depth inside the shell pieces 4, 5. Although not particularly limited, the sponge is made of polyurethane foam. Although the hardness of the sponge is not particularly limited, it is exemplified as a sponge that is not of extreme repulsive force such as high repulsion or low repulsion, but is of a soft type between them, but a sponge with high repulsion or low repulsion can also be used. In this example, the sponge disposed in each shell body 2 is integrally formed in a rectangular parallelepiped shape, but for example, a plurality of sponges formed by dividing them in the vertical direction can also be used. When such a plurality of sponges are used, it is possible to provide gaps between each sponge, but in this case, each sponge may bend toward the gap side, which may reduce the adhesion to the surface of the chain 10, so it is preferable to narrow the gap. Furthermore, when such a plurality of sponges are used, the thickness of each sponge in the vertical direction can improve adhesion to the surface of the chain 10, based on the vertical length of the link 10a that constitutes the chain 10 to be cured. The manner in which the sponge is disposed on the inner surface of the shell 2 is not particularly limited, but examples thereof include a fixed arrangement using double-sided tape, caulking agent, adhesive, etc., a detachable arrangement using double-sided tape, hook-and-loop fastener, etc., and a detachable arrangement by pressing a sponge formed into a shape slightly larger than the inner shape of the shell 2 into the shell 2.

[0037] The size of the capsule for curing 1 in this embodiment is not particularly limited, but the following sizes are exemplified. Shell 2 thickness (material thickness): 2mm Inner size of shell 2: Long side direction (Ia) 107 mm x short side direction (Ib) 42 mm x height (Ic) 142 mm in plan view Size of through hole 6 of shell 2: narrowest part in short side direction (Ha) 23 mm × long side direction (Hb) 90 mm Diameter (Da) of the enlarged portion 6a (larger) of the through hole 6 of the shell 2: 35 mm Diameter (Db) of the enlarged portion 6b (smaller) of the through hole 6 of the shell 2: 25 mm Outward extension length of protruding part 2c (Lj): 7.5 mm Sponge size: Width (Wa) 93mm x Thickness (Wb) 32mm x Height (Wc) 145mm

[0038] Next, we will explain the curing method using the curing capsule 1 of the present invention. As shown in Figure 7, this method includes a step of attaching the curing capsule 1 to the area to be cured of the chain 10 (step S51), and a step of curing the area to be cured via the curing capsule 1 by curing the shell 2 of the curing capsule 1 (step S52).

[0039] In the mounting stage (step S51), the locking portion 8 of the curing capsule 1 is unlocked to open the two shell pieces 4, 5 around the hinge portion 7, and the area of ​​the chain 10 to be protected is positioned between the sponges serving as powder / granular material drop prevention materials 3 arranged inside the two shell pieces 4, 5. The two shell pieces 4, 5 are then closed around the hinge portion 7, and the locking portion 8 of the curing capsule 1 is locked to maintain the closed state. Note that multiple curing capsules 1 may be connected vertically depending on the length of the area of ​​the chain 10 to be protected.

[0040] In the stage of carrying out the protective covering (step S52), the periphery of the protected portion of the chain 10 is covered with a protective sheet, and the protective sheet and the protective capsule 1 are adhered with a protective tape, whereby the protective covering is completed.

[0041] When removing the protection, simply carry out the above steps in reverse.

[0042] According to the curing capsule 1 of this embodiment configured as described above and the curing method using the same, the shell 2 having the powder / granular material fall prevention material 3 disposed therein is fitted to the cured portion of the chain 10, so that the powder / granular material can be prevented from falling downward along the surface of the chain 10. The shell 2 is formed by dividing it into two shell pieces 4, 5, and the two adjacent shell pieces 4, 5 are connected to each other by a hinge portion 7 so as to be able to open and close, so that the shell 2 can be easily and quickly fitted to and removed from the cured portion of the chain 10. Furthermore, since the curing capsule 1 prevents the powder / granular material from falling downward along the surface of the chain 10, the curing of the curing capsule 1 can be easily performed, and therefore the curing can be easily removed.

[0043] Moreover, the powder / granular material drop prevention members 3 are disposed on the inner surfaces of the shell pieces 4, 5. According to this configuration, when the shell pieces 4, 5 are disposed so as to surround the periphery of the chain 10, the powder / granular material drop prevention members 3 disposed on the inner surfaces of the shell pieces 4, 5 can be disposed so as to surround the periphery of the chain 10.

[0044] In addition, the locking unit 8 is capable of locking the shell pieces 4, 5, which are opened and closed by the hinge unit 7, in a closed state and releasing the lock. With this configuration, the locking unit 8 can easily maintain the state where the chain 10 is attached to the protected area and release the attached state.

[0045] Moreover, the shell 2 is provided with a protruding portion 2c at each of the upper and lower ends that protrudes toward the outer periphery of the shell 2, and is configured so that the shell 2 maintains a substantially similar posture to when it is wrapped around the cured portion of the chain 10 by the protruding portion 2c being in contact with the substantially horizontal plane 20. According to this configuration, the shell 2 can be easily wrapped around the cured portion of the chain 10 when the cured portion of the chain 10 is directly above a substantially horizontal plane, since the protruding portion 2c maintains a substantially similar posture to when it is wrapped around the cured portion of the chain 10 by the protruding portion 2c. Moreover, when a curing sheet is fixed to the shell 2 with a curing tape, the protruding portion 2c can be used as a locking portion. Furthermore, the rigidity of the shell 2 can be improved by providing the protruding portion 2c.

[0046] In addition, the capsule 1 for curing in this embodiment is configured to be symmetrical from top to bottom. This configuration allows it to be used facing either up or down, improving the ease of use when attaching it.

[0047] Furthermore, the curing method using the curing capsule 1 of this example includes a step (step S51) of attaching the curing capsule 1 to the cured portion of the chain 10, and a step (step S52) of curing the portion to be cured through the curing capsule 1 by curing the shell 2 of the curing capsule 1. According to this method, it is possible to obtain the same effect as that of the curing capsule 1.

[0048] Next, Fig. 8 shows a second embodiment of the present invention. This curing capsule 1 and the curing method using it are mainly different from the first embodiment in the following points. Therefore, the parts common to the first embodiment are given the same reference numerals and the duplicated explanation will be omitted.

[0049] The capsule 1 for health care in this example is equipped with a magnet 30 for attracting the magnetic material contained in the powdered material. In this example, the magnet 30 is a sheet-like magnet made by forming a rubber magnet, which is made by powdering ferrite magnet and kneading it into rubber, or a plastic magnet, which is made by kneading it into plastic, into a flexible sheet. The sheet-like magnet has slits 30a at the portions located within the enlarged diameter portions 6a and 6b of the through hole 6 to facilitate the arrangement of the chain 10. A groove 2e is formed on the inside of the protruding portion 2c, and the sheet-like magnet as the magnet 30 is detachable from the groove 2e.

[0050] According to the curing capsule 1 of this embodiment and the curing method using the same, in addition to the same effects as the first embodiment, the following effects can be obtained. That is, in this embodiment, a magnet 30 is provided for attracting the magnetic material contained in the powder / granules. According to this configuration, when a magnetic material is used as a blast abrasive, the magnet 30 can improve the effect of preventing the powder / granules from falling.

[0051] The present invention is not limited to the above-described embodiment, and can be embodied by making appropriate modifications without departing from the spirit of the invention, for example, as described below. (1) As shown in Fig. 9, a space 35 may be provided in the vertical middle of the sponge as the powder / granular material fall prevention material 3, and the space 35 may be filled with gel 36 for capturing powder / granular material, thereby improving the powder / granular material fall prevention effect. The size of the space 35 is not particularly limited, but an example is a sponge as the powder / granular material fall prevention material 3 hollowed out in a rectangle with a width (Sa) of 87 mm and a height (Sb) of 18 mm. The gel 36 is not particularly limited, but an example is a mixture of borax, liquid glue, and water. (2) The shape of the protective capsule 1 may be appropriately changed (for example, by omitting the protruding portion 2c as shown in Figure 10), or the protective capsule 1 may be formed specifically for a single chain 10 (for example, by making it into the shape shown in Figure 11).
