Description

[Technical field]

[0001] The present invention relates to a closing device for a long material penetration portion in a thermal insulation wall and a closing method for a long material penetration portion. [Background technology]

[0002] Conventionally, there has been a structure for wiring and piping material to penetrate an insulating wall (see, for example, Patent Document 1). This insulating wall penetration structure includes an insulating block body 13 having a through hole 13a formed therein, as shown in FIG. 16. The insulating block body 13 is disposed on one surface 11b of the insulating wall 11 such that the through hole 13a communicates with the through hole 11a of the insulating wall 11, and the wiring and piping material 12 is disposed so as to pass through the through hole 11a and the through hole 13a. Therefore, a filler 14 made of a foaming insulating material is filled in the gap between the inner surface of the through hole 13a and the wiring and piping material 12 so as to block the through hole 13a through which the wiring and piping material 12 has passed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-24019 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional insulating wall penetration arrangement structure, there was a risk that the filler 14 filling the gap between the inner surface of the through hole 13a and the wiring / piping material 12 would not fill the gap to the back. In particular, if the gap was small, the filler 14 would adhere to and harden on the outer surface of the wiring / piping material 12 or the inner surface of the through hole 13a before reaching the back, and there was a risk that the filler 14 would not be able to fill the through hole 13a sufficiently.

[0005] This invention has been made to solve the above-mentioned conventional disadvantages, and its object is to provide a blocking device for a long material penetration portion and a blocking method for a long material penetration portion, which can sufficiently fill the through hole with filler material. [Means for solving the problem]

[0006] In order to achieve the above object, the closing device for a long material penetration portion and the closing method for a long material penetration portion according to the present invention have the following configuration. The closing device for a long material penetration part according to the invention described in claim 1 is a closing device for closing a long material penetration part where a long material penetrates a through hole formed in an insulating wall. This closing device includes a first insulating block body having insulating performance and a second insulating block body having insulating performance. Here, the first insulating block body includes a first through hole having a size that allows the long material to pass through and penetrating the long material, and a fixing surface that is fixed to a wall surface of the insulating wall so that one end side of the first through hole is connected to the through hole. The second insulating block body includes a second through hole having a size that allows the long material to pass through and penetrating the long material, and a joint that is joined to the first insulating block body so that one end side of the second through hole is connected to the other end side of the first through hole. With the first insulation block body fixed to the insulation wall, a filler made of a foam insulation material can be filled into the gap between the inner surface of the first through hole and the long material from the other end side of the first through hole so as to block the first through hole through which the long material passes. Then, with the second insulation block body joined to the first insulation block body filled with the filler, a filler made of a foam insulation material can be filled into the gap between the inner surface of the second through hole and the long material from the other end side of the second through hole so as to block the second through hole through which the long material passes.

[0007] According to this blocking device, the blocking device includes a first insulating block body fixed to the wall surface of the insulating wall and a second insulating block body joined to the first insulating block body. The first insulating block body includes a first through hole, and the second insulating block body includes a second through hole, and a long material that passes through the through hole of the insulating wall is passed through the first through hole and the second through hole. The first through hole and the second through hole are blocked by a filler that fills the gap between the long material. That is, the blocking device includes a first insulating block body and a second insulating block body that are aligned along the long material, and the long material penetration part of the insulating wall is blocked by the insulating block body and the filler. Therefore, the filler can be filled in stages by arranging the first insulating block body and filling the first through hole with the filler, and then arranging the second insulating block body and filling the second through hole with the filler, thereby allowing the filler to be fully filled in the through hole.

[0008] The closing device for a long material penetration part according to the invention recited in claim 2 is the closing device for a long material penetration part according to claim 1, wherein the second insulation block body is composed of a plurality of divided bodies divided by a dividing surface that divides the second through hole vertically. This makes it possible to place the second insulation block body from the side of the long material. Therefore, the second insulation block body can be installed even after the first insulation block body and the long material have been installed.

[0009] The closing device for a long material penetration part according to the invention of claim 3 is the closing device for a long material penetration part according to claim 2, wherein the second insulating block body has a joined part on the opposite side to the joint part. The joined part is formed so that a joint part of another second insulating block body made of the same article as the second insulating block body can be joined thereto, and the joining connects one end side of the second through hole of the other second insulating block body to the other end side of the second through hole of the second insulating block body. This allows the second insulating block body and the other second insulating block body to be continuously connected along the long material, thereby expanding the insulation range.

[0010] The closing device for a long material penetration part according to the invention recited in claim 4 is the closing device for a long material penetration part according to claim 2, wherein the first insulating block body is composed of a plurality of divided bodies divided by a dividing surface that divides the first through hole vertically. This makes it possible to place the first insulating block body from the side of the long material. Therefore, the first insulating block body can be installed even after the long material has been installed.

[0011] The closing device for a long material penetration part according to the invention recited in claim 5 is the closing device for a long material penetration part according to any one of claims 1 to 4, wherein the outer shape of the first insulating block body becomes smaller from the fixing surface toward the joining part to which the joining part of the second insulating block body is joined. The second insulating block body is contained inside the outer periphery of the fixing surface when the second insulating block body is joined to the first insulating block body, as viewed from the extending direction of the second through hole. This makes it possible to efficiently insulate the long material penetration part without increasing the size of the closing device.

[0012] The method for closing a long material penetration part according to the invention recited in claim 6 is a method for closing a long material penetration part where a long material penetrates a through hole formed in an insulating wall. This closing method includes first fixing a first insulation block body having insulating performance and a first through hole penetrating the first through hole to a wall surface of the insulating wall so that one end side of the first through hole is connected to the through hole with the long material being passed through the first through hole, and filling a filler made of a foaming insulation material from the other end side of the first through hole into a gap between the inner surface of the first through hole and the long material passed through the first through hole to close the first through hole. Then, a second insulation block body having insulating properties and a second through hole passing therethrough is joined to the first insulation block body so that one end side of the second through hole is connected to the other end side of the first through hole with the long material passed through the second through hole, and a filling material made of a foamable insulation material is filled from the other end side of the second through hole into the gap between the inner surface of the second through hole and the long material passed through the second through hole, thereby sealing the second through hole.

[0013] According to this blocking method, the filler is filled in stages by placing a first insulating block body and filling the first through hole with the filler, and then placing a second insulating block body and filling the second through hole with the filler, thereby enabling the filler to be filled sufficiently inside the through hole. Effect of the Invention

[0014] According to the blocking device for a long material penetration portion and the blocking method for a long material penetration portion of the present invention, the filler can be filled in stages using a first insulating block body and a second insulating block body lined up along the long material, thereby allowing the filler to be sufficiently filled into the through hole.

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0017] Figures 1 to 14 show one embodiment of the present invention. In the figures, reference numeral 1 denotes an insulating wall. 1a denotes a through hole formed in the insulating wall 1. 2 denotes a long material such as wiring or piping material (wiring material or piping material). 3 denotes a long material penetration portion where the long material 2 penetrates the through hole 1a. 4 denotes a blocking device for blocking the long material penetration portion 3 (more specifically, blocking on one wall surface of the insulating wall 1).

[0018] The blocking device 4 for the long material penetration portion 3 includes a first insulating block body 5 having insulating properties and a second insulating block body 6 having insulating properties. The first insulating block body 5 includes a first through hole 5a having a size that allows the long material 2 to pass through and penetrating the first insulating block body 5, and a fixing surface 5c that is fixed to the wall surface 1b of the insulating wall 1 so that one end side 5b of the first through hole 5a is connected to the through hole 1a of the insulating wall 1. The second insulating block body 6 includes a second through hole 6a having a size that allows the long material 2 to pass through and penetrating the first insulating block body 5, and a joint portion 6c that is joined to the first insulating block body 5 so that one end side 6b of the second through hole 6a is connected to the other end side 5d of the first through hole 5a.

[0019] Therefore, with the first insulation block body 5 fixed to the insulation wall 1 (more specifically, the wall surface 1b), a filler 7a(7) made of a foam insulation material can be filled from the other end side 5d of the first through hole 5a into the gap between the inner surface of the first through hole 5a and the long material 2 so as to block the first through hole 5a through which the long material 2 passes. Then, with the second insulation block body 6 joined to the first insulation block body 5 filled with the filler 7a(7), a filler 7b(7) made of a foam insulation material can be filled from the other end side 6d of the second through hole 6a into the gap between the inner surface of the second through hole 6a and the long material 2 so as to block the second through hole 6a through which the long material 2 passes.

[0020] Specifically, the first insulation block body 5 is composed of a plurality of divided bodies 5f, 5f divided by a dividing surface 5e that divides the first through-hole 5a vertically. Similarly, the second insulation block body 6 is composed of a plurality of divided bodies 6f, 6f divided by a dividing surface 6e that divides the second through-hole 6a vertically.

[0021] The second insulating block body 6 has a joint portion 6g on the opposite side to the joint portion 6c. The joint portion 6g is formed so that a joint portion 6c of another second insulating block body 601(6) made of the same material as the second insulating block body 6 can be joined to the joint portion 6g. By the joining, one end side 6b of the second through hole 6a of the other second insulating block body 601(6) is connected to the other end side 6d of the second through hole 6a of the second insulating block body 6.

[0022] More specifically, the outer shape of the first insulation block body 5 becomes smaller from the fixing surface 5c toward the joining portion 5g to which the second insulation block body 6 is joined. The second insulation block body 6 is formed so as to fit inside the outer periphery of the fixing surface 5c when the second insulation block body 6 is joined to the first insulation block body 5, as viewed from the extending direction of the second through-hole 6a.

[0023] Specifically, the insulating wall 1 has a sandwich structure in which a layer of insulating material made of, for example, expanded polystyrene is sandwiched between plates (not shown) such as metal plates. The insulating wall 1 forms, for example, a vertical wall or ceiling of a freezer or refrigerator, and may be disposed vertically, horizontally, or at an angle. The foam insulating material that becomes the filler 7 is made of, for example, urethane foam.

[0024] The first heat insulating block body 5 is made of, for example, polystyrene foam. The first heat insulating block body 5 is formed in a hemispherical shape, and the flat part of the hemisphere becomes the fixing surface 5c. The first through hole 5a has an expansion part (diameter enlarged part) at one end on the fixing surface 5c side, and the inner wall of the main body extends cylindrically, so that the first heat insulating block body 5 is a block body that is almost solid so as to surround the first through hole 5a. In detail, the first through hole 5a is opened from the center of the fixing surface 5c toward the upper side of the spherical part 5h of the hemisphere (in detail, the first through hole 5a is opened from the center of the fixing surface 5c in a direction perpendicular to the fixing surface 5c, and the fixing surface 5c side becomes the one end side 5b, and the upper side of the spherical part 5h becomes the other end side 5d). Therefore, the gap between the inner surface of the first through hole 5a and the elongated material 2 can be filled with a filler 7a (7) made of a foaming insulating material from the other end side 5d to the one end side 5b of the first through hole 5a. In addition, the first insulating block body 5 is provided with a protruding portion 5i (for example, a protruding portion serving as a gripping portion) protruding outward from the upper portion of the hemispherical spherical portion 5h. In detail, the protruding portion 5i is formed in a rectangular shape in a plan view and is provided so as to surround the first through hole 5a at the upper portion of the hemispherical spherical portion 5h. Therefore, the protruding portion 5i and the periphery surrounding the protruding portion 5i become the joined portion 5g.

[0025] The first insulation block body 5 (specifically, the fixing surface 5c) is fixed to the wall surface 1b of the insulation wall 1 by an adhesive 8a such as a caulking material. In the illustrated embodiment, a groove 5j is provided in the fixing surface 5c so as to surround the first through-hole 5a, and the adhesive 8a such as a caulking material is applied so as to fill the groove 5j.

[0026] As described above, the first insulation block body 5 is composed of a plurality of divided bodies 5f, 5f (two in the illustrated embodiment) divided by a dividing surface 5e. Here, the two divided bodies 5f, 5f have the same shape, and the dividing surface 5e is provided with a recessed portion 5k and a protruding portion 5m, and the two divided bodies 5f, 5f are aligned with each other by fitting the recessed portion 5k and the protruding portion 5m of each of the divided bodies 5f, 5f together. These divided bodies 5f, 5f are fixed to each other by an adhesive (not shown) such as a caulking material. In the illustrated embodiment, a groove 5n is provided in the dividing surface 5e, and an adhesive such as a caulking material is applied so as to fill the groove 5n.

[0027] The second insulating block body 6 is made of, for example, polystyrene foam, like the first insulating block body 5. The second insulating block body 6 is formed in a cylindrical shape, and the second through hole 6a is provided in the axial center portion. The inner wall of the through hole 6a extends in a cylindrical shape, and the second insulating block body 6 is a block body that is almost filled with the second through hole 6a so as to surround the second through hole 6a. Therefore, from the other end side 6d to the one end side 6b of the second through hole 6a, the gap between the inner surface of the second through hole 6a and the long material 2 can be filled with a filler 7b (7) made of a foaming insulating material. One side of the second insulating block body 6 becomes the joining portion 6c, and the other side becomes the joined portion 6g. Therefore, the joining portion 6c is provided with a recessed portion 6h into which the protruding portion 5i of the first insulating block body 5 fits. The joined portion 6g of the second insulating block body 6 is formed in the same shape as the joined portion 5g of the first insulating block body 5, and the joined portion 6g has a protruding portion 6i that protrudes outward.

[0028] The second heat insulating block body 6 (more specifically, the joint portion 6c) is joined to the first heat insulating block body 5 (more specifically, the jointed portion 5g) by an adhesive 8c such as a caulking material. Here, a groove 6j is provided in the joint portion 6c so as to surround the recessed portion 6h, and the adhesive 8c such as a caulking material is applied so as to fill the groove 6j.

[0029] In the illustrated embodiment, the blocking device 4 is provided with another second insulating block body 601(6) made of the same material as the second insulating block body 6, and this other second insulating block body 601 (more specifically, the joint portion 6c) is joined to the second insulating block body 6 (more specifically, the joint portion 6g) by an adhesive 8d such as a caulking material that fills the groove 6j.

[0030] As described above, the second heat insulating block body 6 is composed of a plurality of divided bodies 6f, 6f (two in the illustrated embodiment) divided by a dividing surface 6e. Here, the two divided bodies 6f, 6f have the same shape, and the dividing surface 6e is provided with a recessed portion 6k and a protruding portion 6m, and the two divided bodies 6f, 6f are aligned with each other by fitting the recessed portion 6k and the protruding portion 6m of each of the divided bodies 6f, 6f together. These divided bodies 6f, 6f are fixed to each other by an adhesive (not shown) such as a caulking material. In the illustrated embodiment, a groove 6n is provided in the dividing surface 6e, and an adhesive such as a caulking material is applied so as to fill the groove 6n.

[0031] Next, a method for blocking the long-material-penetrating portion 3 will be described. This blocking method is a method for blocking the long-material-penetrating portion 3, and first, a first insulation block body 5 having a heat insulating performance and a first through hole 5a penetrating therethrough is fixed to a wall surface 1b of the insulation wall 1 so that one end side 5b of the first through hole 5a is connected to the through hole 1a of the insulation wall 1 with the long-material 2 being passed through the first through hole 5a, and a filler 7a (7) made of a foam insulation material is filled from the other end side 5d of the first through hole 5a into the gap between the inner surface of the first through hole 5a and the long-material 2 passed through the first through hole 5a, thereby blocking the first through hole 5a (see FIG. 3). Then, a second insulation block body 6 having a heat insulating property and a penetrating second through hole 6a is joined to the first insulation block body 5 so that one end side 6b of the second through hole 6a is connected to the other end side 5d of the first through hole 5a with the long material 2 being passed through the second through hole 6a, and a filler 7b (7) made of a foaming insulation material is filled from the other end side 6d of the second through hole 6a into the gap between the inner surface of the second through hole 6a and the long material 2 passed through the second through hole 6a to close the second through hole 6a (see FIG. 4). At this time, the first through hole 5a of the first insulation block body 5 and the second through hole 6a of the second insulation block body 6 are positioned on a straight line.

[0032] In the illustrated embodiment, a second insulation block body 601(6) made of the same material as the second insulation block body 6 is joined to the second insulation block body 6 such that, with the long material 2 passed through the second through hole 6a of the second insulation block body 601(6), one end side 6b of the second through hole 6a of the second insulation block body 6 is connected to the other end side 6d of the second through hole 6a of the second insulation block body 6. From the other end side 6d of the second through hole 6a of the second insulation block body 601(6), a filler 7b(7) made of a foam insulation material is filled into the gap between the inner surface of the second through hole 6a and the long material 2 passed through the second through hole 6a to close the second through hole 6a (see Figures 1 and 2). At this time, the second through hole 6a of the second insulating block body 6 and the second through hole 6a of another second insulating block body 601(6) are positioned on a straight line, whereby the first through hole 5a and the two second through holes 6a, 6a are positioned on a straight line.

[0033] Next, the effects of the closing device 4 for the long material penetration portion 3 and the closing method for the long material penetration portion 3, which are configured as described above, will be described. The closing device 4 includes a first insulating block body 5 fixed to the wall surface 1b of the insulating wall 1, and a second insulating block body 6 (and further another second insulating block body 601(6) in the illustrated embodiment) joined to the first insulating block body 5. The first insulating block body 5 includes a first through hole 5a, and the second insulating block body 6 (and further another second insulating block body 601(6) in the illustrated embodiment) includes a second through hole 6a, and the long material 2 penetrating the through hole 1a of the insulating wall 1 is passed through the first through hole 5a and the second through hole 6a. The first through hole 5a and the second through hole 6a are blocked by a filler 7 that fills the gap between the long material 2 and the first through hole 5a and the second through hole 6a. That is, a first insulating block body 5 and a second insulating block body 6 (and, in the illustrated embodiment, a second insulating block body 601 (6)) are used as the blocking device 4, which are arranged along the long material 2, and the long material penetration portion 3 of the insulating wall 1 is blocked by these insulating block bodies 5, 6 and filling material 7.

[0034] Therefore, the first insulating block body 5 is placed and the first through hole 5a is filled with filler 7a (7), and then the second insulating block body 6 is placed and the second through hole 6a is filled with filler 7b (7) (in the illustrated embodiment, another second insulating block body 601 (6) is further placed and the second through hole 6a is filled with filler 7b (7)), thereby allowing the filler 7 made of a foamable insulating material to be filled in stages, thereby allowing the filler 7 to be sufficiently filled inside the through holes 5a, 6a. That is, the filling material 7 is filled stepwise using the first insulating block body 5 and the second insulating block body 6 (and further another second insulating block body 601(6) in the illustrated embodiment) arranged along the long material 2 (i.e., the blocking device 4 is divided into a plurality of insulating block bodies 5, 6 arranged along the long material 2), and thus the filling material 7 can be sufficiently filled into the through holes 5a, 6a with the filling material 7 made of a foaming insulating material without increasing the fluidity of the filling material 7 or increasing the filling pressure (i.e., no insufficient filling occurs). In other words, the blocking device 4 ensures the necessary filling length of the filling material 7 by the total length of the through holes 5a, 5b of the first insulating block body 5 and the second insulating block body 6, and the total length is divided by the plurality of insulating block bodies 5, 6 to prevent insufficient filling of the filling material 7.

[0035] Moreover, because the filler 7 can be filled stepwise along the long material 2 in this way, the gap between the inner surfaces of the through holes 5a, 6a and the long material 2 can be reduced, and less filler 7 made of foamable insulation can be used, making it less expensive. Even if a sufficient insulation effect cannot be obtained with one insulation block body (first insulation block body 5) due to the good thermal conductivity of the long material 2, the insulation effect can be increased by joining another insulation block body (second insulation block body 6).

[0036] In addition to the first insulating block body 5 and the second insulating block body 6, the blocking device 4 is provided with a second insulating block body 601(6) which is made of the same material as the second insulating block body 6. Therefore, the second insulating block body 6 and the second insulating block body 601(6) (i.e., two second insulating block bodies 6) can be continuously connected to the first insulating block body 5 along the elongated material 2, thereby expanding the insulating range.

[0037] The first insulation block body 5 is composed of a plurality of divided bodies 5f, 5f (two divided bodies in the illustrated embodiment) divided by a dividing surface 5e that divides the first through hole 5a vertically. This allows the first insulation block body 5 (specifically, the divided bodies 5f, 5f) to be arranged from the side of the long material 2. Therefore, the first insulation block body 5 can be arranged even after the long material 2 is installed. Similarly, the second insulation block body 6 is composed of a plurality of divided bodies 6f, 6f (two divided bodies in the illustrated embodiment) divided by a dividing surface 6e that divides the second through hole 6a vertically. This allows the second insulation block body 6 (specifically, the divided bodies 6f, 6f) to be arranged from the side of the long material 2. Therefore, the second insulation block body 6 can be arranged even after the first insulation block body 5 and the long material 2 are installed.

[0038] In addition, in the blocking device 4, the outer shape of the first insulating block body 5 becomes smaller from the fixing surface 5c toward the joint portion 5g, and the second insulating block body 6 (in the illustrated embodiment, in addition, another second insulating block body 601(6)) is contained inside the outer periphery of the fixing surface 5c when the second insulating block body 6 is joined to the first insulating block body 5, as viewed from the extending direction of the second through hole 6a. This makes it possible to efficiently insulate the long material penetration portion 3 without increasing the size of the blocking device 4. In other words, the first insulating block body 5 is responsible for insulation of the through hole 1a, and the second insulating block body 6 extending along the long material 2 is responsible for heat conduction of the long material 2, so that the blocking device (blocking device 4) is not excessively insulating, and can be made smaller and less expensive.

[0039] The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the second insulating block body 601(6) may be omitted. Conversely, two or more second insulating block bodies 601(6) may be provided and joined in sequence.

[0040] Furthermore, the other insulating block body to be joined to the joint portion 6g of the second insulating block body 6 does not necessarily have to be the same article as the second insulating block body 6.

[0041] In addition, the first insulation block body 5 is integrated with a plurality of divided bodies 5f, 5f by an adhesive such as a caulking material, but instead of or in addition to this, the periphery may be wrapped with an adhesive tape to integrate or reinforce the integration. The same applies to the second insulation block body 6.

[0042] The first insulating block body 5 does not have to be made up of a plurality of divided bodies 5f, 5f, but may be formed as an integral body from the beginning. Similarly, the second insulating block body 6 does not have to be made up of a plurality of divided bodies 6f, 6f, but may be formed as an integral body from the beginning.

[0043] In addition, the long material 2 does not have to be passed through the through hole 1a of the insulating wall 1 in advance. The long material 2 may be passed through the through holes 5a, 6a of each insulating block body 5, 6 and then through the through hole 1a.

[0044] Furthermore, the second insulating block body 6 may be shaped so as to cover the entire first insulating block body 5 except for the fixing surface 5c, as shown in FIG.

[0045] The first and second insulating block bodies 5 and 6 may be made of other materials having insulating properties, not necessarily made of polystyrene foam. The foamable insulating material to be the filler 7 is not limited to urethane foam.

[0046] In the illustrated embodiment, the length of the through holes 5a, 6a from the one end side 5b, 6b to the other end side 5d, 6d (i.e., the length (axial length) of the through holes 5a, 6a) of the second insulating block body 6 is half that of the first insulating block body 5. Therefore, by changing the number of second insulating block bodies 6, the total length of the through holes 6a can be set finely. In addition, the filler 7b(7) is filled separately in the second insulating block body 6 and in the other second insulating block body 601(6) joined to the second insulating block body 6. However, the filler 7b(7) may be filled all at once in the second through holes 6a, 6a that connect the other end side 6d of the other second insulating block body 601(6) to the one end side 6b of the second insulating block body 6 in a joined state.

[0047] In the illustrated embodiment, two second insulating block bodies 6 are used, such as by joining another second insulating block body 601(6) made of the same material as the second insulating block body 6 to the second insulating block body 6, but instead, the second insulating block body 6 may be enlarged to double the length of the second through hole 6a and the length of the second through hole 6a may be made the same as the length of the first through hole 5a of the first insulating block body 5. Even in this case, the length of the second through hole 6a of the enlarged second insulating block body 6 is the same as the length of the first through hole 5a of the first insulating block body 5, and the second through hole 6a can be filled with the filler 7b(7) made of a foam insulating material.
