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

  The winding member 1 for a long body of the present invention is a member configured to perform a series of operations from winding around a long body to fixing. Here, the synthetic resin pipe 2 (for example, see FIG. 2A) is cited as the long body, but it may be an electric cable or an electric cable configured by covering a plurality of electric wires. .

  As shown in FIG. 1A, the long body winding member 1 is configured by winding a long belt-like member in a roll shape. The roll-shaped member for winding a long body 1 is used in the form of a strip shown in FIG. 1B by unwinding and cutting the predetermined length L required. The predetermined length L is set according to the size of the outer dimensions of the pipe 2. Specifically, both ends of the long body winding member 1 wound around the pipe 2 can be overlapped and fixed to the pipe 2. The length is set so as to ensure the overlapped portion. Then, the strip-like and rectangular long winding member 1 is wound around the pipe 2 (see FIGS. 2A, 2B, and 2C). The winding member 1 for a long body is flexible so that it can be wound around a pipe 2, and has a winding body 3 having adhesiveness on one surface and the adhesiveness of the winding body 3. And a release material 4 that is releasably held on the surface. Below, the circumferential direction used as the direction which winds the winding member 1 for elongate bodies around the piping 2 is made into a length direction, and the direction orthogonal to this length direction is demonstrated as a width direction.

  As shown in the enlarged view of FIG. 1B, the winding body 3 is formed on an aluminum sheet 5 having a high heat shielding property and a surface 5A of one of the aluminum sheets 5 (left side in the enlarged view of FIG. 1B). It is comprised from two members of the thermally expansible sheet 6 integrated. The aluminum sheet 5 is configured by laminating various synthetic resin films on one side or both sides of an aluminum foil. The thermally expandable sheet 6 is configured to have a size equivalent to that of the aluminum sheet 5 and, when used in a fire prevention compartment area to be described later, expands due to heat at the time of fire occurrence and closes the entire through hole 7A of the wall 7. It is composed of a heat-expandable graphite-containing resin. Further, the thermally expandable sheet 6 is provided with adhesiveness by containing butyl rubber having adhesiveness at room temperature as a resin component, and the aluminum sheet 5 is used as one of the thermally expandable sheets 6 by utilizing the adhesiveness. It can be held (fixed) on the surface 6B. Further, the release material 4 can be held (fixed) on the other surface (surface opposite to the aluminum sheet 5) 6 </ b> A of the thermally expandable sheet 6 by utilizing the adhesiveness of the thermally expandable sheet 6. Here, although the thermal expansion sheet 6 which becomes effective at the time of fire occurrence in a fire prevention division area is shown, the sound insulation sheet for performing sound insulation, the heat insulation sheet for performing heat insulation, the vibration proof sheet for suppressing vibration, It can be changed depending on the purpose of use, such as a display sheet for displaying a mark. In addition, the aluminum sheet 5 can also be changed into the sheet | seat member comprised by another material similarly to the thermally expansible sheet 6, or can be abbreviate | omitted.

  The mold release material 4 is releasably held on the other surface 6A of the thermally expandable sheet 6 using the adhesiveness of the thermally expandable sheet 6 as described above. Moreover, the release material 4 is comprised from the synthetic resin film (paper may be sufficient) to which the magic cut (trademark registration) was given. Examples of the synthetic resin constituting the film include polyethylene, but other synthetic resins may be used. The synthetic resin film having such a configuration can be cut by hand along the width direction at an arbitrary position in the length direction. In addition to Magic Cut (registered trademark), a notch (or also referred to as a groove) cut into a V-shape, U-shape, or I-shape or a perforation in which a large number of holes are formed may be used. Further, it may be excellent in straight-line cutability that can be easily cut straight along the width direction. Moreover, the widthwise dimension of the release material 4 is larger than the widthwise dimension of the winding body 3, and the enlarged portion protrudes outward from one end of the winding body 3. Yes. Accordingly, as shown in FIG. 1 (c), the end portion 4A protruding to one outer side in the width direction (upward in FIG. 1 (c)) at the length direction one end portion 4T of the release material 4 is immediately provided. It is possible to quickly perform the cutting operation of the release material 4 by grasping. FIG. 1 (d) shows a state in which the end 6 </ b> T in the length direction of the release material 4 is cut and the adhesive surface 6 </ b> A of the thermally expandable sheet 6 constituting the winding body 3 is exposed. . Here, since it protrudes outward (upward in FIG. 1 (b)) in the entire length direction of one end of the winding body 3 in the width direction, it protrudes at any position in the length direction. The one end of the release material 4 in the width direction can be immediately grasped, which is preferable, but may be configured to protrude outward only at an arbitrary position in the length direction. Further, since the release material 4 covers the entire surface of the thermally expandable sheet 6 of the winding body 3, the entire area of the adhesive surface 6 </ b> A of the thermally expandable sheet 6 can be reliably covered with the release material 4. When winding the long body winding member 1 around the pipe 2, it is possible to prevent a part of the adhesive surface 6 </ b> A from coming into contact with the pipe 2. Moreover, in FIG.1 (d), although the length direction one end part 4T of the mold release material 4 has shown the state cut | disconnected in the direction orthogonal to a length direction, and was cut off into the rectangular shape, it cross | intersects a length direction In some cases, it is cut in a direction to be trapped, for example, trapezoidal.

  A procedure for winding the long body winding member 1 around the pipe 2 for construction will be described. As shown in FIG. 2 (a), the long body winding member 1 cut into a strip shape having the required length as described above is wound around the pipe 2 so that the length direction is the circumferential direction. . At this time, the long member winding member 1 is arranged and wound so that the release material 4 faces the outer surface of the pipe 2. And after winding, the surface 6A which has the adhesiveness of the thermally expansible sheet 6 of the winding main body 3 of the part which the length direction both ends of the winding member 1 for long bodies overlapped is exposed, ie, thermal expansibility. The release material 4 is cut along the width direction so that the adhesive surface 6A at the end of winding of the sheet 6 is exposed. At the time of this cutting, one end portion (end portion on the winding end side) 1A of the long body winding member 1 is turned to the other end portion (end portion on the winding start side) 1B up to the position indicated by the phantom line in FIG. 1A in the width direction at one end portion 4T in the length direction of the release material 4 (one end portion protruding in the width direction, one end portion protruding toward the front in the figure) 4A in the width direction. Cut along (see FIG. 2B). After cutting, a surface having adhesiveness that is exposed by superimposing one end portion (end portion on the winding end side) 1A of the long-body winding member 1 on the other end portion (end portion on the winding start side) 1B. 6A contacts the outer surface of the other end portion (end portion on the winding start side) 1B. Thereby, the superposition | polymerization part 1C of the winding member 1 for elongate bodies can be joined (refer FIG.2 (c)). In short, polymerization is performed so that the surface 6A having the adhesiveness of the thermally expandable sheet 6 of the winding body 3 provided in the long member wrapping member 1 is exposed by winding the long member wrapping member 1 around the pipe 2. Construction of the winding member 1 for a long body is performed by a series of operations in which the release material 4 in the part 1C is cut by hand to join the superposed part 1C. In addition, when winding the long member winding member 1 around the pipe 2 so that the length direction is the circumferential direction, the other end of the long member winding member 1 (the winding start side) is not shown. The end portion of the release member 4 of 1B is cut off only a part of the adhesive surface 6A that is exposed and fixed to the pipe 2 and temporarily fixed, so that the winding member for a long body is wound with one hand when winding. There is no need to hold down the other end portion 1 (end portion on the winding start side) 1B firmly, and there is an advantage that the winding operation can be performed easily and quickly.

  3 (a) and 3 (b), a pipe through which the long member winding member 1 is inserted into the through holes 7A and 7A formed in the pair of walls 7 and 7 which are fire prevention compartments in the fire prevention compartment region. 2 shows the case of winding and construction. In this case, the heat-expandable sheet 6 is expanded by the heat at the time of the fire and closes the through hole 7A, so that it is possible to prevent a flame, a toxic gas, or the like from flowing into the adjacent room.

  A procedure for winding the long body winding member 1 around the pipe 2 inserted through the through holes 7A and 7A will be described. The long body winding member 1 cut into the required length by cutting as described above is wound around the pipe 2 so that the length direction is the circumferential direction in a wide space outside the through hole. At this time, the long member winding member 1 is arranged and wound so that the release material 4 faces the outer surface of the pipe 2. Then, after the winding, the release material 4 in the longitudinal direction is exposed so that the adhesive surface 6A of the winding body 3 of the portion where the longitudinal ends of the winding member 1 for the long body overlap each other is exposed. Cut along the width direction at any position. At the time of this cutting, as described above, the one end portion (end portion on the winding end side) 1A of the long member winding member 1 is moved to the other end portion (winding start side) up to the position indicated by the phantom line in FIG. After being separated from the end portion 1B of the mold release material 4, one end portion 4T in the width direction (one end portion protruding in the width direction) 4A in the length direction one end portion 4T is grasped and cut along the width direction (FIG. 2 (b)). After cutting, a surface having adhesiveness that is exposed by superimposing one end portion (end portion on the winding end side) 1A of the long-body winding member 1 on the other end portion (end portion on the winding start side) 1B. The superposed portion 1C of the long member winding member 1 can be joined with 6A (see FIG. 2C). Thereafter, the wound member for long body 1 wound and joined is moved with respect to the pipe 2 so as to be positioned in the through hole 7A. At the time of this movement, since the release material 4 is made of a synthetic resin film, the movement resistance can be reduced, and the long member winding member 1 can be moved with a small force. As described above, even when the other end portion (end portion on the winding start side) 1B of the long member winding member 1 is temporarily fixed to the pipe 2, it is not firmly fixed. The movement of the wrapping member 1 will not be hindered. After the movement, the gap between the outer surface of the pipe 2 and the through holes 7A and 7A is filled with a filler 8 such as a mortar, a non-combustible material, a putty, or an elastic member to complete the construction (FIG. 3 (a ), (B)). When filling the filler 8, the width direction one end portion 4 </ b> A of the release material 4 protruding from the winding main body 3 is made to protrude from the filler 8 to the outside (see FIG. 3A). By doing in this way, it is possible to easily grasp that the long-body winding member 1 is mounted by looking at the one end portion 4A of the released release material 4 even after the filler 8 is filled. There are advantages. Moreover, also in this construction, as described above, the adhesiveness of the thermally expandable sheet 6 of the winding body 3 provided in the long member winding member 1 by winding the long member winding member 1 around the pipe 2. The long member winding member 1 is constructed by a series of operations in which the release material 4 in the overlapped portion 1C is cut by hand to join the overlapped portion 1C so as to expose the surface 6A having the above.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention. The long body winding member 1 can be configured, for example, as shown in FIGS. In FIG. 4A, the release material 4 is configured to protrude outward from both ends in the width direction. In this case, each of the protruding both ends 4H and 4H may be configured to protrude by the same length, or may be configured to protrude at different lengths. Moreover, in FIG.4 (b), the mold release material 4 is comprised by the magnitude | size equivalent to the winding main body 3 (or may be a little smaller size than the winding main body 3), and the winding main body 3 side of the release material 4 is shown. One end of the width direction (the back area 4B in FIG. 4B) on the surface (the back surface of the release material 4 in FIG. 4B) is not attached to the adhesive surface of the winding body 3. It has been released. By performing the release treatment in this way, even when the release material 4 is configured to have the same size as the winding body 3 (or a little smaller than the winding body), the release material 4 is used when cutting. The one end portion 4A in the width direction can be rolled up and easily gripped. In FIG.4 (b), although the part (upper side area | region 4B) by which the mold release process was carried out was formed with the same width over the whole length direction, it is not restricted to this. The release treatment is performed by applying or spraying a release agent such as silicone or fluororesin to a predetermined region (upper region 4B) on the back surface of the release material 4. Moreover, in FIG.4 (c), the mold release material 4 is comprised in the magnitude | size equivalent to the winding main body 3 (or may be a little smaller size than the winding main body 3), and the winding main body 3 side of the release material 4 is shown. Both end portions in the width direction (upper region 4B and lower region 4b in FIG. 4 (c)) of the surface (the rear surface of the release material 4 in FIG. 4 (c)) adhere to the adhesive surface of the winding body 3 It has been released from the mold. By performing the release treatment in this way, even when the release material 4 is configured to have the same size as the winding body 3 (or a little smaller than the winding body), the release material 4 is used when cutting. The one end 4A or the other end 4C in the width direction can be lifted up and easily gripped. In FIG. 4C, the two regions 4B and 4b that have been subjected to the mold release process are formed to have the same width over the entire length direction, but this is not restrictive. Moreover, although one area | region 4B and the other area | region 4b by which the mold release process was carried out are comprised by the same width | variety, you may comprise by the different width | variety. The release treatment is performed by applying or spraying a release agent such as silicone or fluororesin to predetermined regions (upper region 4B and lower region 4b) on the back surface of the release material 4.

  In the said embodiment, although the winding main body 3 was comprised from two members, it may be comprised from one member and may be comprised from three or more members. In addition, the specific structure of the member which comprises the winding main body 3 can be freely changed according to a use purpose.

  Moreover, in the said embodiment, although the member (in this embodiment, heat-expandable sheet 6) which comprises the winding main body 3 itself was comprised so that it might have adhesiveness, the release material 4 was comprised, but an adhesive was apply | coated and the adhesion layer May be provided. In this case, the release material 4 is detachably held on the winding main body 3 through the adhesive layer.

  Moreover, in the said embodiment, although the winding member 1 for elongate bodies wound by roll shape was shown, the winding member 1 for elongate bodies comprised by the predetermined | prescribed length may be sufficient.

As shown, the long member winding member 1 may be arranged and wound so that the aluminum sheet 5 faces the outer surface of the pipe 2 (so that the aluminum sheet 5 is located on the innermost side). This aluminum sheet 5 can also be comprised from various resin sheets. In the case of this resin sheet, since the bondability with the winding body 3 is excellent, there is an advantage that it is not easily peeled off from the winding body 3 at the time of winding or bending, for example, and is easy to handle. is there. As described above, since the release material 4 is positioned on the outermost side after the elongate body winding member 1 is wound around the pipe 2, as shown in FIG. After removing the one end portion 4T, the other end portion (winding start side end portion) 1B of the long member winding member 1 is separated from the pipe 2 and one end portion (winding portion) of the long member winding member 1 is wound. End portion 1A is pressed against the outer surface of pipe 2. The other end portion (start of winding) of the long body winding member 1 separated from the pipe 2 on one end portion (end portion on the winding end side) 1A of the long body winding member 1 in the pressed state.
