JP-A-2006-29023

In the seal member of Patent Document 1, when there are a plurality of pipes (long bodies), there are often a plurality of pipes having different diameters, so a valley occurs between the pipes. It is difficult to make it follow the outer peripheral surface of the pipe so that there is no gap. As a result, the gaps between the pipes cannot be sufficiently sealed, and the fire resistance deteriorates, and early improvement is desired.

SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention aims to provide a treatment tool capable of reliably closing even if there is a gap between elongated bodies.

In order to solve the above-described problems, the fixture of the present invention is used in a partition through structure in which a partition through-hole is formed in a partition body of a building and at least one elongated body is inserted through the partition through-hole. A measuring tool, comprising: a tubular sleeve member that can be inserted into the partition through-hole; A cylindrical cover member that can be reduced in diameter with respect to the scale body, and a thermal expansion material disposed on the inner surface of the sleeve member are provided. It is characterized in that a plurality of cuts are formed with spaces therebetween, and tongue-like blocking pieces are formed between the cuts that are adjacent in the circumferential direction.

According to the present invention, when the cover member is reduced in diameter with respect to the elongated body to cover the elongated body, the tongue-like blocking piece enters the gap generated between the elongated bodies. Thereby, the gap between the elongated bodies can be reliably closed by the tongue-shaped closing piece.

Moreover, as a measure tool of the present invention, the cut may include an oblique cut that intersects with the axial direction.

As described above, since the incisions include oblique incisions intersecting with the axial direction, the portions of the blocking piece corresponding to the oblique incisions become oblique shapes intersecting in the axial direction. Obstruction pieces are likely to enter into.

Moreover, as a measure tool of the present invention, the cut may include a linear cut along the axial direction on the tip side of the oblique cut.

As described above, the incision includes an oblique incision and a linear incision along the axial direction on the tip side of the oblique incision, so that the portion of the blocking piece corresponding to the oblique incision has an oblique shape, while the tip side of the oblique incision becomes oblique. Since the portion corresponding to the linear cut has a linear shape along the axial direction, the closing piece enters the gap between the elongated bodies to reliably close the gap between the elongated bodies.

Further, as the measuring tool of the present invention, the tip portion of the cover member may be provided with a shape retaining means for retaining a reduced diameter shape.

As described above, the distal end portion of the cover member is provided with the shape-retaining means for retaining the reduced-diameter shape. It is easy to maintain a posture in which the body enters the gap between the long bodies.

Further, in the measuring tool of the present invention, the shape-retaining means may be formed by stacking the tip portion of the cover member.

As described above, the shape-retaining means is formed by stacking the tip portion of the cover member, thereby enhancing the shape-retaining performance of the tip portion of the cover member. As a result, it is easy to maintain a posture in which the tongue-shaped blocking piece enters the gap between the elongated bodies.

Further, in the measuring tool of the present invention, the shape-retaining means may be provided with a wire that maintains a reduced-diameter shape at the distal end portion of the cover member.

As described above, by providing the wire rod that maintains the reduced diameter shape at the distal end portion of the cover member, the shape retention performance of the distal end portion of the cover member can be enhanced.

Further, in the measuring instrument of the present invention, the cover member may be non-bonded to the elongated body.

When the elongated body expands and contracts due to thermal expansion or thermal contraction, if the cover member is not adhered to the elongated body, the tongue-like blocking piece can be elongated while allowing the elongated body to expand and contract. It is easy to maintain a posture that enters the gap between the bodies.

ADVANTAGE OF THE INVENTION According to the present invention, it is possible to provide a treatment tool that can reliably close even if there is a gap between elongated bodies by forming a tongue-shaped blocking piece between the cuts that are adjacent in the circumferential direction. can.

FIG. 8 is a side view of the compartment penetrating structure to which the mounting device with the cover member shown in FIG. 7 is attached;

Hereinafter, an embodiment of a treatment tool used in the compartment penetrating structure of the present invention will be described based on the drawings.

In the partition penetration structure, a partition through-hole is formed in a floor or a wall, which is a partition body provided in a partition part of a building, and a long body is inserted through the partition through-hole. A gap is generated between the inserted long body and the partition through-hole, and a tool is used to eliminate this gap. In this embodiment, a wall will be described as an example.

As shown in FIGS. 1 to 3, the measuring tool H is mounted on three elongated pipes 1A, 1B, and 1C of different sizes, and has a circular shape formed on a wall (partition) 2. A cylindrical sleeve member 4 configured to be insertable into the partition through-hole 3, and a plurality of (three in FIG. ), and a cylindrical cover member 5 whose diameter can be reduced for the pipes 1A, 1B, and 1C. Two pipes 1A, 1B out of the pipes 1A, 1B, 1C are wrapped with heat insulating materials 6A, 6B. Examples of the elongated body include refrigerant pipes, heat medium pipes, hot water supply pipes, water supply pipes, drain pipes, hydraulic pipes, gas pipes, electric wire pipes, electric wires (power lines and signal lines), cables, and the like. The wall 2 is composed of two walls 2A and 2B spaced apart in the axial direction to form an internal hollow wall.

The sleeve member 4 includes a cylindrical sleeve main body 41 formed by rolling a metal (for example, steel) thin plate into a ring shape, and a thermal expansion material 42 attached to the inner surface 41A of the sleeve main body 41. , and a gap hiding portion 43 attached to the outer surface 41B of the sleeve main body 41 at one axial end (the right end in FIG. 2). Therefore, by rounding the sleeve body 41 so as to have an outer diameter dimension corresponding to the inner diameter dimension of the partitioned through-hole 3 , the sleeve body 41 can be configured to be inserted into the partitioned through-hole 3 . After the sleeve main body 41 is inserted through the partitioning through-hole 3 , the sleeve main body 41 with its reduced diameter expands outward due to its elastic restoring force, thereby pressing the sleeve main body 41 against the partitioning through-hole 3 and partitioning the sleeve main body 41 . The sleeve main body 41 and the partitioning through-hole 3 can be shielded without creating a gap with the through-hole 3 .

In addition, the sleeve body 41 has a dimension in the circumferential direction orthogonal to the axial direction that is larger than the diameter dimension of the partitioning through-hole 3, and an axial dimension that is longer than the axial dimension of the partitioning through-hole 3. have dimensions. In addition, as shown in FIG. 4, the sleeve body 41 has a plurality of elongated portions spaced apart along the entire circumference in the vicinity of the substantially central portion in the axial direction of the thermal expansion material 42 attached to the sleeve body 41 . Two rows of holes 41a and 41b are formed. These two rows of elongated holes 41a and 41b are formed parallel to each other and arranged in a zigzag pattern. The length is set so that it overlaps with the long hole 41b on the side) in the axial direction. In other words, the long hole 41a or 41b exists at any portion of the sleeve body 41 in the circumferential direction. Therefore, when the thermal expansion material 42 expands, a part of the thermal expansion material 42 bulges to the outside of the sleeve body 41 through the long holes 41 a and 41 b, and the through hole 3 of the wall 2 and the outer surface of the sleeve body 41 . It is designed to be able to fill the gap between

The thermal expansion material 42 has a circumferential dimension across the entire circumferential direction perpendicular to the axial direction of the sleeve body 41, and has a dimension covering the entire axial direction from one axial end to the other axial end. Therefore, when the sleeve body 41 is inserted into the partition through-hole 3 , both the one axial end and the other axial end of the thermal expansion member 42 protrude axially outward of the partition through-hole 3 . . In this embodiment, the thermal expansion member 42 has a dimension extending from one axial end to the other axial end of the sleeve body 41 in the axial direction, but it may have a dimension shorter than the entire axial direction.

The thermal expansion material 42 is a member having thermal expansibility (the property of increasing its volume when heated) and fire resistance (the property of easily withstanding heat, having a high melting temperature and being difficult to burn). As the thermal expansion material 42, known materials can be used without particular limitation, and for example, a putty-like member (thermally expansible putty-like refractory material) can be used. In addition, when the thermal expansion material 42 is heated to a predetermined temperature (for example, 180° C.) or more, it expands in the thickness direction and the outer surfaces of the pipes 1A, 1B, 1C (the two pipes 1A, 1B are heat-insulated). By filling the gap between the outer surfaces 1a and 1b of the members 6A and 6B, the outer surface 1c of the remaining pipe 1C, and the inner surface 41A of the sleeve body 41, the flame generated on one side of the partitioned through-hole 3 is prevented from reaching the partitioned through-hole 3. Prevents movement to the other side. Since the sleeve member 4 contains the thermal expansion material 42 in this manner, the sleeve member 4 has thermal expansion properties.

The gap hiding part 43 is composed of a band-like elastic member that can be deformed in a reversible manner, such as sponge, soft rubber, foamed polyurethane foam, etc., and hides the gap between the through hole 3 and the outer surface of the sleeve body 41. When the sleeve main body 41 is inserted into the partition through-hole 3, the sleeve main body 41 abuts against the wall surface 2a of one of the walls 2A constituting the partition through-hole 3, thereby preventing the sleeve main body 41 from inside the partition through-hole 3. It also functions as a stopper for positioning.

Further, the gap hiding portion 43 is adhered to the outer surface of one axial end portion of the sleeve body 41 with an adhesive. And, when the diameter of the sleeve body 41 is reduced, it can be attached to the outer surface of the sleeve body 41 so that the diameter-reduced state can be maintained. Specifically, as shown in FIG. 4, one end of the gap hiding portion 43 includes an extension portion 43A extending outward in the circumferential direction from one end of the sleeve body 41, The gap-hiding part 43 is attached to the sleeve body 41 so that the end is located closer to one end than the other end of the sleeve body 41 . Therefore, the extending portion 43A of the gap hiding portion 43 can be attached to the outer surface of the other end of the sleeve main body 41 in a state where the outer diameter of the sleeve main body 41 is reduced so that it can be inserted into the partitioning through-hole 3. Therefore, the state where the diameter of the sleeve body 41 is reduced can be maintained. An adhesive (not shown) is applied to the inner surface of the extending portion 43A, and the adhesive is covered with a release paper (not shown). When attaching to the outer surface of the part, the extending part 43A is cut so as not to create a gap between the tip of the extending part 43A of the gap hiding part 43 and the other end of the gap hiding part 43. After adjusting the length, the release paper is removed and the extended portion 43A of the gap hiding portion 43 is attached to the outer surface of the other end of the sleeve main body 41 to maintain the reduced diameter state of the sleeve main body 41. , constitutes an uninterrupted annular gap hiding portion 43 (see FIG. 3).

The cover member 5 includes a cover main body 51 made of, for example, a sheet of flame-retardant aluminum glass cloth, a cover-side thermal expansion material 52 provided on the inner surface of the cover main body 51 on the tip side, and a cover-side thermal expansion material. A shape-retaining means 53 arranged on the distal end side of 52 for retaining the shape of the distal end portion in a reduced diameter shape; and a foam material 54 for filling the gap between the cover main body 51 and the inner surface 51A.

As shown in FIG. 1 , by forming a plurality of cuts 55 at intervals in the axial direction of the cover main body 51 , the gap between the cuts 55 , 55 adjacent in the circumferential direction is a tongue piece. The closure piece 56 is configured in the shape of a Also, the base end of the cover body 51 is adhered to the outer surface of one axial end of the sleeve body 41 with an adhesive over the entire circumferential direction. One circumferential end of the cover main body 51 is provided with an extending portion 51B extending outward from the one circumferential end of the sleeve main body 41 in the circumferential direction. Therefore, when the sleeve body 41 is rolled into a ring shape to reduce its diameter, the extending portion 51B is formed on the outer surface 51C of the cover body 51 at the other end in the circumferential direction so as not to create a gap at the overlapped portion of the cover body 51. It is attached with an adhesive. An adhesive (not shown) is applied to the inner surface 51b of the extending portion 51B, and a release paper (not shown) is attached. Then, when the extending portion 51B is attached to the outer surface of the sleeve main body 41 at the other end in the circumferential direction, the release paper is peeled off.

Each cut 55 includes an oblique cut 55A that intersects with the axial direction, and a straight cut 55B along the axial direction on the tip side of the oblique cut 55A. More specifically, as shown in FIG. 6(a), straight cuts 55B of double length along the axial direction and oblique cuts 55A crossing the axial direction from both ends of the straight cuts 55B in the axial direction. , 55A are formed, and are folded back at a folded portion 55C (see dotted line) at a point of half the length of the double linear cut 55B in the longitudinal direction, thereby forming a layered structure consisting of two blocking pieces 56, 56. (see FIG. 6(b)). By forming the front end portion of the cover main body 51 to have an overlapping structure in this way, the shape retaining means 53 for maintaining the diameter-reduced shape of the front end portion of the cover main body 51 is formed. In this way, the cut 55 includes the diagonal cut 55A and the straight cut 55B on the tip side of the diagonal cut 55A, so that the portion of the blocking piece 56 corresponding to the diagonal cut 55A has an oblique shape, while the tip side Since the portion corresponding to the linear cut 55B has a linear shape along the axial direction, the blocking piece 56 enters the gap S (three places in FIG. 3) between the pipes 1A, 1B, 1C to close the pipes 1A, 1B, To surely close a gap S between 1C. Thereby, it can prevent that fireproof performance falls. Further, since the straight cut 55B starts from the tip 55T of the cover main body 51, even if the worker folds the cover at the folding portion 55C (see the dotted line) with a slight deviation, the deviation is not only noticeable, but also the tip 55T. Since an acute angle portion is not formed with respect to the tip 55T, it is possible to make the tip 55T hard to sharpen or become fuzzy.

The cover-side thermal expansion member 52 is formed of a belt-like body having dimensions extending over the entire circumferential direction of the cover main body 51 and is formed of the same material as the thermal expansion member 42 . As described above, the cover-side thermal expansion member 52 expands in its thickness direction when heated to a predetermined temperature (for example, 180° C.), and the outer surfaces of the pipes 1A, 1B, and 1C and the inner surface of the cover body 51 expand. 51A prevents the flame generated on one side of the partitioning through-hole 3 from moving to the other side of the partitioning through-hole 3 .

The shape-retaining means 53 is composed of a metal wire 53A as a wire material that maintains the diameter-reduced state of the front end portion of the cover body 51 . The wire 53A is fixed to the inner surface of the tip of the cover main body 51 by the foam material 54 as described above, and when the sleeve main body 41 is contracted (rolled), the wire 53A is formed into an annular shape, and the tip of the cover main body 51 It is possible to improve the shape retention performance of the part. Further, by providing the wire 53A, the front end portion of the cover body 51 can easily maintain the reduced diameter shape, and the tongue-shaped blocking piece 56 can easily maintain the posture in which it enters the gap S between the pipes 1A, 1B, and 1C. . In this embodiment, both the wire rod (wire 53A) and the overlapping structure of the front end portion of the cover body 51 are used as the shape retaining means 53, but only one of them may be provided.

The foam material 54 is composed of, for example, a strip of sponge, but may be composed of a reversibly deformable belt-shaped elastic member such as soft rubber or a foam material such as polyurethane foam. The foam material 54 fills the gaps between the pipes 1A, 1B, 1C and the inner surface 51A of the cover body 51 when the cover body 51 is contracted.

A procedure for covering the gap S between the pipes 1A, 1B, and 1C by attaching the instrument H configured as described above to the partition through-hole 3 will be described.

4 and 5 is prepared, the sleeve body 41 of the measure is rounded and adjusted so that it can be inserted into the partition through-hole 3, and after the adjustment, the gap hiding part 43 extends. The portion 43A (see FIG. 4) is adhered to the outer surface 41B of the other end of the sleeve body 41 to maintain the state where the diameter of the sleeve body 41 is reduced. Subsequently, the extending portion 51B (see FIGS. 4 and 5) of the cover body 51 is attached to the outer surface 51C (see FIGS. 4 and 5) of the cover body 51 at the other end in the circumferential direction. After that, the cylindrical sleeve body 41 is inserted through the partition through-hole 3 from the base end side opposite to the cover member 5 side. During this insertion, the gap hiding portion 43 of the sleeve body 41 contacts the wall surface 2a of one wall 2A of the partition through-hole 3. As shown in FIG. This completes the insertion of the sleeve body 41 into the partition through-hole 3 .

Next, after the pipes 1A, 1B and 1C are passed through the measure H, the tip portion of the cover body 51 is reduced in diameter so that the inner surface 51A of the cover body 51 is aligned with the outer surfaces 1a, 1b and 1c of the pipes 1A, 1B and 1C. (see FIG. 1). At this time, the blocking piece 56 can enter the gaps S between the pipes 1B, 1C and 1C, 1A which are adjacent to each other in the radial direction and have different diameters, as well as between the pipes 1B, 1A, so that the gaps S can be reliably closed (Fig. 3). In the present invention, since the cover main body 51 is not adhered to the pipes 1A, 1B, 1C, even if the pipes 1A, 1B, 1C expand or contract due to thermal expansion or thermal contraction, the cover main body 51 is attached to the pipes 1A, 1B. , and 1C, it is easy to maintain the posture in which the tongue-shaped blocking piece 56 enters the gap S between the pipes 1B, 1C and 1C, 1A and between the pipes 1B, 1A.
