Description

  The present invention relates to a through-hole belonging to a partition body, such as a through-hole formed in a partition body such as a wall or a floor, or a through-hole formed with a metal sleeve penetrating and fixed to the partition body, and a cable inserted through the through-hole. The present invention relates to a through-hole obturator provided at an opening formed with the outer peripheral surface of the through-body or a portion near the opening of the through-body and a through-hole obstruction structure using the same.

Conventionally, through-holes belonging to the compartment side, such as through-holes formed in compartments such as walls and floors, or through-holes formed with metal sleeves that are fixedly penetrated to the compartments, and through cables etc. As the through-hole obturator for the opening formed with the outer peripheral surface of the body, a curable putty that can be reliably closed in accordance with the shape of the opening is used because it can be filled in a softened state. However, curable putty is difficult to work in a softened state, so the operator may vary in the accuracy of the closure, and a certain amount of time must elapse before curing. To solve these problems,
(1) A rectangular rod-shaped through-hole obturator that can be bent and deformed along the outer peripheral surface of a through-body inserted through a through-hole belonging to the partitioning body and that can be radially deformed.
(2) A strip-shaped through-hole obturator that can be wound a plurality of times along the outer peripheral surface of the penetrating body that is inserted into the through-hole belonging to the partitioning body and that can be deformed in a radial direction (the following patent) Reference 1).
The through-hole obturator as described in said (1) and (2) is proposed.
Japanese Utility Model Publication No.2-116086

  Among these through-hole obturators, in the case of the above (1), since the through-hole obturator is formed into a square bar shape, it is not deformed in a softened state during the closing operation, and therefore a curable putty is used. As compared with the above, it is possible to suppress the variation in the closing accuracy by the operator, and in the state where the rectangular bar-shaped through hole obturator is bent and deformed along the outer peripheral surface of the through body, the through hole and the outer peripheral surface of the through body The through hole closing work can be completed simply by inserting it into the annular opening formed by or by fixing it to the outer end surface of the opening, and the work content compared to using a curable putty. However, when the through hole obturator is bent and deformed along the outer peripheral surface of the through body, the inner and outer portions of the through hole obturator Due to the difference in the diameter (or curvature) of Since the inner portion is contracted and deformed in the circumferential direction by the circumferential compression force acting on the inner portion, and the outer portion is stretched and deformed in the circumferential direction by the circumferential tensile force acting on the outer portion, the through hole For example, when the outer peripheral surface of the penetrating body is not a cylindrical curved surface, or the outer peripheral surface of the penetrating member is individually a cylindrical curved surface. Even if there is unevenness due to a plurality of penetrating bodies being gathered and arranged, the through-hole obturator can be formed by pressing the through-hole obturator against the penetrating body and contracting and deforming the contact portion. Even if it is intended to contact almost the entire outer peripheral surface of the penetrating body, the portion that has already been contracted and deformed in the circumferential direction by the circumferential compressive force to the inner portion cannot be sufficiently contracted and deformed in the radial direction. The part cannot be brought into contact with the outer peripheral surface of the penetrating body. There is a possibility that a gap occurs in the opening for.

  On the other hand, in the case of the above (2), since the through-hole obturator is formed in a thin strip shape, it does not deform in a softened state during the closing operation, so that it depends on the operator as compared with the case where a curable putty is used. While it is possible to suppress variation in the closing accuracy and to be laminated by winding around the outer peripheral surface of the penetrating body, even if the inner and outer portions of the stacked through-hole obturator have different bending diameters, The circumferential compression force acting as compared with the case of (1) can be reduced, and the through-hole obturator is compressed by pressing the through-hole obturator against the penetrator and contracting and deforming the contact portion in the radial direction. However, in the through hole closing operation, the strip-like through hole obturator is moved along the outer peripheral surface of the penetrating body until its thickness is equal to or larger than the diameter of the opening. Must be wound several times In addition, when this through-hole obturator is used in a through-hole closing method in which the through-hole closing tool is interposed between the inner peripheral surface of the through-hole and the outer peripheral surface of the through-hole, the through-hole closing device is first wound and laminated. Since the through body must be inserted into the through hole, the work content becomes complicated and the work time becomes longer than in the case of (1).

  The present invention has been made in view of the above circumstances, and its main problem is to suppress the formation of a gap in the opening formed by the through hole and the through body inserted through the through hole. It is possible to provide a through-hole obturator capable of simplifying the work contents and shortening the work time.

  A first characteristic configuration of the present invention relates to a through-hole obturator, the feature of which is an opening formed by a through-hole belonging to the partitioning body and an outer peripheral surface of the through-body inserted through the through-hole, or an opening of the through-body. Permits relative movement in the circumferential direction between adjacent layers of a plurality of plugging materials that can be equipped in a radially laminated state in the vicinity and that can be deformed in the radial direction, and the plurality of plugged materials in a stacked state. And a restraining means for restraining in the state of being.

  In other words, with this configuration, each layer can move in the circumferential direction between adjacent layers when the occluding material laminated in the radial direction is bent and deformed and installed in the vicinity of the opening or the opening of the penetrating body. As a result, when it is pressed against the outer peripheral surface of the penetrating body without the circumferential compression force to the inner part and the circumferential tensile force to the outer part acting like the square bar-shaped conventional technology In addition, since the shrinkage and deformation performance in the radial direction can be sufficiently exhibited, the deformation can be performed in accordance with the shape of the outer peripheral surface of the penetrating body.

  In addition, since the plurality of blocking materials are constrained in a state of being stacked in the radial direction, for example, it is not necessary to equip each opening with the respective blocking materials separately as in the case where the plurality of blocking materials are not constrained. Further, it is not necessary to wind and laminate a plurality of times in the circumferential direction as in the prior art formed in a thin strip shape.

  Therefore, it is possible to suppress the generation of a gap in the opening, and it is possible to simplify the work content and shorten the work time.

  The second characteristic configuration of the present invention is a preferable configuration in the implementation of the first characteristic configuration, and the characteristic is that the restraining means can be included in a state in which the blocking materials are stacked, and more than this blocking material. The bag-shaped body has a large circumferential length.

  In other words, with this configuration, it is possible to constrain the blocking material in a state in which a plurality of the blocking materials stacked by the bag-like body covering the periphery of the blocking material is allowed to move relative to the adjacent layers. It is possible to prevent the blocking material from coming into contact with and damage the through-hole or the penetrating body when installing, and further, the blocking material can be closed without directly touching the blocking material. The through hole closing work can be performed regardless of the scientific nature of the above, and the through hole closing work can be simplified.

  The third characteristic configuration of the present invention is a preferable configuration in the implementation of the second characteristic configuration. The characteristic is that the bag-shaped body is made of a waterproof material and the closure material is inserted into the bag-shaped body. The insertion port for use is configured so as to be closed by polymerizing the opening edge.

  That is, with this configuration, the insertion port for inserting the closure material in the bag-like body can be closed in a state in which the plurality of occlusion materials in the stacked state are enclosed in the waterproof bag-like body. Can be prevented from entering the inside of the bag-like body and the blocking material getting wet with water, and the opening formed by the through hole and the through body inserted through the through hole or the vicinity of the opening of the through body Since it can suppress that water approachs into an opening part when it equips with, it can suppress that water approachs to a division body side through a through-hole.

  Therefore, the deterioration of the soundproof performance and the heat insulation performance of the partition body due to the through-hole obturator and the partition body containing water can be suppressed.

  The fourth feature configuration of the present invention is a preferred configuration in the implementation of any one of the first to third feature configurations. The feature is that the plugging material is composed mainly of a refractory material. There is in point.

  In other words, with this configuration, when a through-hole obturator mainly composed of a refractory material is installed in an opening formed by the through-hole and a through-body inserted through the through-hole obturator, a flame is generated in the opening. Since it can suppress entering, the fall of the fireproof performance of the division body by a through-hole can be suppressed.

  The fifth characteristic configuration of the present invention is a preferable configuration in the implementation of any one of the first to fourth characteristic configurations. The characteristic is that the closing material contains a thermally expandable material. There is in point.

  In other words, with this configuration, when the opening formed by the through hole and the through body inserted through the through hole is equipped, the through body melts or burns out due to a flame or heat, and a gap is formed in the through hole. Even if this occurs, the plugging material is thermally expanded and the gap can be closed, so that it is possible to suppress the intrusion of flames and heat into the partition through the through hole. A decrease in fire resistance can be further suppressed.

  The sixth feature configuration of the present invention is a preferred configuration in the implementation of any one of the first to fifth feature configurations, and the feature is that the closing material contains a soundproof material. In the point.

  That is, according to this configuration, when the opening is formed by the through hole and the through body inserted through the through hole, it is possible to suppress leakage of sound to the partition body side through the through hole.

  The seventh characteristic configuration of the present invention is a preferable configuration in the implementation of the first to sixth characteristic configurations, and the characteristic is that the blocking material is a foam having a cellular structure.

  In other words, with this configuration, when the opening formed by the through hole and the through body inserted through the through hole is provided by the heat insulation and cushioning characteristic of the bubble structure, the insulation of the partition body by the through hole is provided. It is possible to suppress the deterioration of performance and to suppress the transmission of vibration to the partition by absorbing the vibration of the penetrating body, and to suppress the generation of noise from the partition due to the vibration of the penetrating body. be able to.

  The eighth characteristic configuration of the present invention is a preferable configuration in the implementation of the first to seventh characteristic configurations, and the feature is that the circumferential length of the closing material is provided at both ends thereof in a state of being mounted on the opening. It exists in the point which is formed in the length which parts can contact | abut from the circumferential direction.

  In other words, with this configuration, a single through-hole obturator is bent or deformed in the radial direction, and an opening formed by the through-hole and a through-body inserted through the through-hole or a portion near the opening of the through-body Since it is possible to close the opening by installing it in, for example, compared with the case where the opening is closed using a plurality of through-hole closing tools, the work content for closing the through-hole is simplified. Work time can be shortened.

  A ninth characteristic configuration of the present invention relates to a through-hole blocking structure, which is characterized in that the through-hole blocking tool according to any one of claims 1 to 8 is inserted into the through-hole belonging to the partitioning body side. It is in the point equipped with the opening part formed with the outer peripheral surface of the penetrating body or the vicinity of the opening part of the penetrating body.

  In other words, with this configuration, a simple work content can be constructed in a short work time, but a gap is formed in the opening formed by the through hole and the outer peripheral surface of the through body inserted through the through hole. Can be suppressed, and the deterioration of the performance of the partition can be suppressed by the through hole.

[First Embodiment]
1 to 3, for example, as shown in FIGS. 4 to 8, a through-hole formed in a partition body such as a wall W or a floor, or a metal sleeve H <b> 1 fixed to the partition body. In order to close the annular opening Ha formed by the through hole H belonging to the partition body side and the outer peripheral surface of a long through body such as a cable K inserted through the partition hole, the opening Ha or the through body The through-hole obstruction | occlusion tool A equipped with the opening part Ha vicinity is shown, and this through-hole obstruction | occlusion tool A is cyclic | annular which makes the object of the several obstruction | occlusion material 2 of a thin plate shape in the thickness direction (radial direction of the through-hole H). It is enclosed in the restraint bag 1 (an example of restraint means and a bag-like body) in a state of being laminated until the radial length (thickness) is larger than the radial length of the opening Ha.

  The plugging material 2 contains unfired vermiculite powder, which is an example of a heat-expandable material, so that it mainly expands in the presence of heat-insulated rock wool, which is an example of a fire-resistant material and a sound-proof material, so as to expand in a fire. It is configured and provided with flexibility and compressibility that can be curved and deformed in an annular shape. The width d2 is formed with an appropriate width according to the purpose of fireproofing, soundproofing, etc., and the longitudinal length (circumferential length) 1 is along the outer peripheral surface of the penetrating body in a state of being laminated in the radial direction. So that the end faces of the two end portions 2d in the longitudinal direction of the closing member 2 located in the innermost layer can be contacted (contacted) from the circumferential direction when covering the outer peripheral surface of the penetrating body. It is formed with the same or substantially the same length as the outer peripheral length of the penetrating body.

  The restraining bag 1 has a transparent polyethylene film as an example of a waterproof material laminated on the inner surface of the translucent nonwoven fabric to provide translucency and waterproofness, and has an insertion port 1a having one side opened. The joining portion (the overlapping portion around the storage space) to be removed is thermally welded to form a bag, and the opening edge portion of the insertion port 1a is polymerized in a state where the plurality of blocking materials 2 are inserted into the inside through the insertion port 1a. The insertion port 1a is closed by the above, and the occlusion material 2 is prevented from getting wet by water due to the waterproofness of the bag-like body 1, and at the same time, when the opening Ha or a portion near the opening Ha of the penetrating body is equipped. The light-transmitting property of the bag-like body 1 makes it possible to confirm the closed state of the opening Ha by the internal closing material 2.

  The radial length D1 of the restraining bag 1 is slightly longer than the radial length d1 of the plurality of closing materials 2, and the width D2 thereof is slightly larger than the width d2 of the closing materials 2. It is formed with a width, and the surplus spaces S1 and S2 are formed between the longitudinal direction both ends 2d of the closing material 2 and the longitudinal ends of the restraining bag 1 in a state of including the closing material 2, respectively. The longitudinal length L is formed to be longer than the longitudinal length l of the closing material 2, and the plurality of closing materials 2 in a stacked state using the surplus spaces S1 and S2 are formed in the longitudinal direction (circumferential By permitting relative movement between the layers adjacent to each other in the direction), and using both side portions of the restraint bag 1 corresponding to the surplus spaces S1, S2 as a gripping portion for handling the through-hole obturator A Without applying external force such as compression to the encapsulating material 2 included, the opening H Or make it possible to be equipped to the opening Ha vicinity portion of the penetrator to suppress damage to the occluder 2.

  Next, the state at the time of use of the through-hole obturator A of the present invention will be described with reference to an example (use example) of a through-hole obstruction structure using the through-hole obturator A. For convenience, among the plurality of blocking materials constituting the through-hole blocking device A, the blocking material positioned on the innermost side when used is the inner layer, the outermost layer is the outer layer, and the blocking material positioned between them. Is described as an intermediate layer.

(A) Usage example 1
As shown in FIG. 4, an annular opening Ha between an inner peripheral surface of a through hole H formed in a wall W that is an example of a partition body and an outer peripheral surface of a plurality of cables K that is an example of a through body. The restraint bags 1 corresponding to the surplus spaces S1 and S2 in a state in which the through-hole obturator A is bent and deformed in a cylindrical shape along the outer peripheral surface of the cable K and covers the outer peripheral surface of the cable K. In this state, the both side portions of the through hole are pushed into the opening Ha from outside and interposed between the inner peripheral surface of the through hole H and the outer peripheral surface of the cable K. The opening Ha is equipped with a compressive force acting in the direction.

  At this time, as described above, the through-hole obturator A is configured to have a radial length larger than the radial length of the opening Ha, so that the through-hole obturator A includes the inner peripheral surface of the through-hole H and the cable. A compressive force acts in the radial direction between the outer peripheral surfaces of K.

  As shown in FIG. 5, the through-hole obturator A equipped in the opening Ha has a larger diameter than the intermediate layer 2 b of the outer layer 2 a (in other words, a smaller curvature). D) The necessary circumferential length for covering the same angle as that of the intermediate layer 2b is insufficient, and both longitudinal ends 2d thereof are relatively moved toward the center in the circumferential direction as compared with the intermediate layer 2b. Since the inner layer 2c has a smaller diameter than the intermediate layer 2b (in other words, because the curvature is increased), an extra circumferential length is required to cover the same angle as the intermediate layer 2b. Compared with the intermediate layer 2b, both end portions 2d in the longitudinal direction move relatively outward in the circumferential direction, and the through-hole obturator A becomes a restraining force against the radial contraction deformation of the through-hole obturator A. No circumferential compression force or circumferential tensile force is applied.

  And the part (clamping part 2e) which contact | connects both the internal peripheral surface of the through-hole H of the through-hole obstruction | occlusion tool A and the outer peripheral surface of the cable K is shrink-deformed in the radial direction by the compression force to the above-mentioned radial direction. On the other hand, a portion not in contact with both the inner peripheral surface of the through hole H or the outer peripheral surface of the cable K, or a portion in contact with one of the inner peripheral surface of the through hole H or the outer peripheral surface of the cable K (non-clamping portion) No compression force acts on 2f), and the non-clamping part 2f does not contract at all, so that the non-clamping part 2f is kept as close as possible to the inner peripheral surface of the through hole H and the outer peripheral surface of the cable K. Thus, the formation of a gap in the opening Ha is suppressed.

  Therefore, it is possible to suppress the passage of flame, smoke, water through the opening Ha into the wall W or the adjacent room side, and the transmission of sound and heat to the wall W or the adjacent room side. Further, the thermal expansion of the non-fired vermiculite powder contained in the closing material 2 can reliably close the gap of the opening Ha, and when the cable K is melted or burned by flame or heat, the portion is heated. The through hole H can be substantially blocked by expanding and entering.

(I) Use example 2
As shown in FIG. 6, in this use example, the locations near the outer side on both opening sides of the annular opening Ha between the inner peripheral surface of the through-hole H formed in the wall W and the outer peripheral surface of the cable K. Then, each of the through-hole obturator A is bent and deformed into a cylindrical shape along the outer peripheral surface of the cable K, and the surplus spaces S1 and S2 are overlapped and temporarily fixed with a tape or the like while covering the outer peripheral surface of the cable K. It is fixed so that the outer surface of the through-hole obturator A is covered from the outer surface of the through-hole H to the outer peripheral surface of the cable K in a state of being pressed against the outer surface (end surface) of the through-hole H formed in the wall W. By winding a constraining tape T in the circumferential direction, the end face of the opening Ha (an example of a portion in the vicinity of the opening Ha) is provided in a state in which a compressive force in the radial direction is applied to the through-hole closing material A. .

  The constraining tape T is configured by providing an acrylic adhesive layer on a base material formed by laminating a glass cloth having heat insulating properties on an aluminum foil.

  Since the state of the through-hole obturator A provided on the end face of the opening Ha is the same as the state described in the first usage example, the description thereof is omitted.

Restraint bags 1 corresponding to the surplus spaces S1 and S2 in a state where the through hole obturator A is bent and deformed along the outer peripheral surface of the cable K to cover the outer peripheral surface of the cable K on both opening sides of the opening Ha. The inner peripheral surface of the through hole H (specifically, the inner peripheral surface of the bushing H2) and the outer peripheral surface of the cable K in a state in which they are overlapped on both sides of the wire and pushed into the opening Ha from the outside to exert a compressive force in the radial direction. So that the through hole obturator A is mounted on the opening Ha. It is made to.

  Since the state of the through-hole obturator A equipped in the opening Ha is the same as the state described in the first usage example, the description thereof is omitted.

(D) Use example 4

The through hole closing member A is bent and deformed along the outer peripheral surface of the cable K and covers the outer peripheral surface of the cable K on the outer sides of the openings Ha, corresponding to the surplus spaces S1 and S2. Superposed on both sides of the restraint bag 1 and temporarily fixed with a tape or the like, and pressed against the end surface of the through hole H (specifically, the end surface of the bushing H2), the outer surface of the through hole H (specifically, the outer periphery of the bushing H2) Surface) to the outer peripheral surface of cable K, through hole closed By winding the adhesive restraining tape T in the circumferential direction so as to cover the outer surface of the tool A, the end face (opening portion) of the opening Ha in a state where a compressive force in the radial direction is applied to the through-hole closing member A An example of the vicinity of Ha).

  Since the state of the through-hole obturator A provided on the end face of the opening Ha is the same as the state described in the first usage example, the description thereof is omitted.
