Description

Technical Field

[0001] The present invention relates to a measure tool used in a partition penetration structure in which partition through holes are formed in partition bodies such as floors and walls provided in partition parts of a building, and a long body is inserted through the partition through holes.

[0002] Conventionally, after inserting a pipe through a partition through hole penetrating the partition body, an operation of filling a gap between the partition through hole and the pipe has been performed.

[0003] For example, when filling the gap between a pipe, which is a long body inserted through a partition through hole formed through a floor, and the partition through hole with mortar, first, the opening at the lower end of the partition through hole is closed with a hole-filling construction material on the lower floor below the upper floor on the floor surface side. After closing the opening at the lower end, move to the upper floor on the floor surface side and fill the partition through hole with mortar from the opening at the upper end of the partition through hole to fill the gap between the pipe and the partition through hole (for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the above Patent Document 1, after performing the operation of closing the opening at the lower end of the partition through hole on the lower floor, it is necessary to move to the upper floor to perform the mortar filling operation, and the operation is troublesome. Incidentally, even when partitioned by a wall on the same floor, after closing the opening at one end of the partition through hole on one adjacent side, moving to the other adjacent side and filling mortar from the opening at the other end of the partition through hole, the same disadvantages as described above occur.

[0006] In view of the above situation, the present invention aims to provide a measure tool that can easily perform the operation of filling the gap between the long body and the partition through hole.

Means for Solving the Problem

[0007] The measure tool of the present invention is a measure tool used for a partition through-hole structure in which a partition through-hole is formed in a partition body of a building and a long body is inserted through the partition through-hole. The measure tool includes a sleeve that is externally mounted on the long body and configured to be insertable into the partition through-hole, and a flange portion that protrudes radially outward from the outer peripheral surface of the sleeve and has an outer diameter larger than the diameter of the partition through-hole. The flange portion is configured to be deformable by contact with the inner peripheral surface of the partition through-hole when the sleeve is inserted into the partition through-hole, and by deforming, it is configured as a filler receiving portion that closes the space between the outer peripheral surface of the sleeve and the inner peripheral surface and receives the filler filled between the partition through-hole and the sleeve.

[0008] According to the present invention, when the sleeve externally mounted on the long body is inserted so as to be positioned within the partition through-hole, the flange portion is deformed by contact with the inner peripheral surface of the partition through-hole, and the partition through-hole can be closed. After closing the space between the outer peripheral surface of the sleeve and the inner peripheral surface of the partition through-hole with the flange portion, by filling the filler from the same side where the sleeve is inserted, the flange portion functions as a filler receiving portion that receives the filler. Therefore, the operation of closing the partition through-hole and the operation of filling the filler into the partition through-hole can be performed on the same side of the partition through-hole.

[0009] Further, the measure tool of the present invention may include a thermal expansion material disposed on the outer peripheral surface of the long body.

[0010] As described above, by providing a thermal expansion material disposed on the outer peripheral surface of the long body, the thermal expansion material expands due to heat such as a flame, and it is possible to prevent the flame generated on one side of the partition through-hole along the outer peripheral surface of the long body from moving to the other side of the partition through-hole.

[0011] Further, the measure tool of the present invention may include a plurality of members in which the sleeve is radially divisible.

[0012] As described above, by integrating a plurality of members that can be split in the radial direction, the sleeve is externally mounted on the long member.

[0013] Moreover, in the measure tool of the present invention, the sleeve is configured to be insertable into the partition through-hole in such a direction that one axial end is on the tip side in the insertion direction and the other axial end is on the rear end side in the insertion direction, and in a state where the sleeve is inserted, the other axial end of the sleeve may be located deeper than the end portion on the front side in the insertion direction of the sleeve in the partition through-hole.

[0014] As described above, in a state where the sleeve is inserted, since the other axial end of the sleeve is located deeper than the end portion on the front side in the insertion direction of the sleeve in the partition through-hole, a portion where only the filling material is in close contact between the partition through-hole and the long member is formed between the other axial end of the sleeve and the end portion on the front side in the insertion direction of the sleeve in the partition through-hole, so that water stoppage can be surely performed.

[0015] Moreover, in the measure tool of the present invention, in a state where the sleeve is inserted, the filling material receiving portion may be located on the front side in the insertion direction of the sleeve rather than the end portion on the rear side in the insertion direction of the sleeve in the partition through-hole.

[0016] As described above, if the filling material receiving portion is located on the front side in the insertion direction of the sleeve rather than the end portion on the rear side in the insertion direction of the sleeve in the partition through-hole, the amount of the filling material filled in the partition through-hole can be reduced.

[0017] Moreover, in the measure tool of the present invention, the sleeve includes one axial end that is on the tip side in the insertion direction and the other axial end that is on the rear end side in the insertion direction, and may be provided with a pushing member provided at the other axial end of the sleeve for pushing the sleeve in the insertion direction when inserting the sleeve into the partition through-hole.

[0018] As described above, when inserting the sleeve into the partition through-hole, the sleeve can be inserted into the partition through-hole by pushing the sleeve in the insertion direction with the pushing member.

[0019] Further, in the measure tool of the present invention, the sleeve has a plurality of members arranged in a cylindrical shape in the circumferential direction, and the plurality of members are arranged such that the circumferential end portions are opposed to the end portions of the adjacent members in the circumferential direction. One of the end portions opposed to each other in the circumferential direction among the plurality of members is openable and closable, and the rest may be connected via a connecting portion rotatable so that the one opens and closes.

[0020] As described above, by opening one of the end portions opposed to each other in the circumferential direction among the plurality of members in the circumferential direction, the sleeve can be easily externally mounted on the long body from the side.

[0021] Further, in the measure tool of the present invention, the flange portion has a cut at one position in the circumferential direction, and the cut may be formed at a position substantially the same as the opening / closing end position of the end portions configured to be openable and closable in the circumferential direction.

[0022] As described above, by providing the flange portion with a cut formed at a position substantially the same as the opening / closing end position of the sleeve in the circumferential direction, the sleeve and the flange portion can be opened from substantially the same position in the circumferential direction, and the sleeve, the flange portion, and the long body can be externally mounted simultaneously from the side.

Effect of the Invention

[0023] According to the present invention, since the operation of closing the partition through-hole and the operation of filling the filling material into the partition through-hole can be performed on the same side, it is possible to provide a measure tool that can easily perform the operation of filling the gap between the long body and the partition through-hole.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, embodiments of the measures used in the partition through-structure of the present invention will be described with reference to the drawings. <First Embodiment>

[0026] In the partition through-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 pipe, which is a long member, is inserted into the partition through-hole. A gap is generated between the inserted pipe and the partition through-hole, and an operation to fill this gap is performed. The measures used for the filling operation are shown in FIG. 1. In this embodiment, the floor will be described as an example.

[0027] As shown in FIGS. 1 to 3, the measures include a sleeve 4 that is externally mounted on the pipe 1 and is configured to be insertable into a partition through-hole 3 formed in the floor 2, a thermal expansion material 5 disposed on the inner surface of the sleeve 4, and a flange portion 6 that protrudes radially outward at the insertion-side tip of the outer peripheral surface of the sleeve 4 and has an outer diameter larger than the diameter of the partition through-hole 3. Further, it is provided with an attachment member 7 for pushing the sleeve 4 externally mounted on the pipe 1 outside (above) the partition through-hole 3 into the partition through-hole 3. Examples of the pipe 1 include a hot water supply pipe, a water supply pipe, a drain pipe, an electric wire pipe, a refrigerant pipe, an electric wire, and a cable.

[0028] The flange portion 6 is configured to be deformable by contact with the inner peripheral surface 3A of the partition through-hole 3 when the sleeve 4 is inserted into the partition through-hole 3, and by deforming, it closes the partition through-hole 3 and is configured as a filler receiving portion for receiving the filler 8 filled between the partition through-hole 3 and the sleeve 4. The flange portion 6 is composed of an elastic member that can be deformably restored, such as a sponge, soft rubber, foamed polyurethane, or other foamed materials. However, it may also be a tubular body with a hollow interior, a bellows-shaped body configured such that the valleys contract and deform, a thin plate-like body made of resin or rubber that becomes thinner from the base to the tip like a fin, and any configuration is acceptable as long as it is configured to receive the poured filler 8 so that it does not drip downward.

[0029] Further, the flange portion 6 is composed of two half-ring bodies 9, 9 in a plan view. The ring bodies 9, 9 are fixed to the half-member 10, 10 described later by double-sided tape, adhesive, or the like. When both end portions of the half-member 10, 10 described later are locked to form a cylindrical shape, the ring bodies 9, 9 constitute an annular flange portion 6 without a break.

[0030] Each ring body 9 has a thinner thickness in the vertical direction at the tip portion (radial outer side) than in the vertical direction at the base end portion (radial inner side) fixed to the half-member 10 described later. Also, the bottom surface (lower surface) 9A of each ring body 9 is an inclined surface that is positioned higher toward the tip side (radial outer side). By configuring it in this way, when the sleeve 4 is inserted into the partition through-hole 3, the ring bodies 9, 9 of the flange portion 6 become a curved concave shape that protrudes outward due to contact with the partition through-hole 3 (see Fig. 5). As a result, the flange portion 6 closes the space between the outer peripheral surface 4A of the sleeve 4 and the inner peripheral surface 3A of the partition through-hole 3 and constitutes a filler receiving portion that reliably receives the filler 8 filled between the partition through-hole 3 and the partition through-hole 3.

[0031] The sleeve 4 is configured to be insertable into the partition through-hole 3 such that one axial end (the lower end in FIG. 2) is on the tip side in the insertion direction and the other axial end (the upper end in FIG. 2) is on the rear end side in the insertion direction. Further, the sleeve 4 is made of synthetic resin (it may be metal) and is configured to be externally attachable to the pipe 1 by integrating two semi-divided members 10, 10 that are semi-circular in plan view and have the same configuration. At one circumferential end of each semi-divided member 10, a U-shaped engaged portion 10A for forming a locking hole 10a protrudes outward in the circumferential direction, and at the other circumferential end, a locking protrusion 10B that can be locked to and unlocked from the locking hole 10a is formed. The locking hole 10a is configured in a vertically long rectangular shape, and the locking protrusion 10B that locks to the locking hole 10a is composed of a protrusion that is vertically long and protrudes radially outward from the outer surface (front surface) of the semi-divided member 10. Therefore, by locking the locking protrusion 10B at the other end of the other semi-divided member 10 facing this to the locking hole 10a at one end of one semi-divided member 10, and locking the locking protrusion 10B at the other end of one semi-divided member 10 to the locking hole 10a at one end of the other semi-divided member 10 facing this, a cylindrical sleeve 4 can be formed.

[0032] On the outer surface of each semi-divided member 10, a large number of protrusions 10T extending in the circumferential direction for a predetermined length in two upper and lower rows are formed at predetermined intervals. These protrusions 10T are for preventing the sleeve 4 from slipping off in the vertical direction from the partition through-hole 3 by biting into the filled and solidified filling material 8. Also, at the upper end of each semi-divided member 10, it is slightly thicker than other parts so that the lower end of the mounting member 7 abuts against it. Further, at the lower end of each semi-divided member 10, a pair of upper and lower ridges 10C, 10C for suppressing the vertical movement of the flange portion 6 are formed. The ridges 10C, 10C extend along the circumferential direction of the semi-divided members 10, 10 and are formed over the entire circumferential area of the semi-divided members 10, 10.

[0033] The thermal expansion material 5 is provided on each of the inner surfaces of the two split members 10, 10, has a circumferential dimension that extends across the entire circumferential direction of each split member 10, and has a dimension slightly smaller than the vertical dimension of each split member 10 so as not to protrude from the upper and lower ends of each split member 10. Further, the thermal expansion material 5 is disposed (deeply) inside the sleeve 4 so as to be disposed on the outer peripheral surface of the pipe 1, and is disposed toward the front side (rear end side) in the insertion direction of the sleeve 4 in a state where a part thereof overlaps radially with the flange portion 6 in the sleeve 4 in the partition through-hole 3. In this way, by disposing the thermal expansion material 5, as shown in FIG. 5, in the portion on the front side (rear end side) in the insertion direction of the sleeve 4 rather than the filler receiving portion (flange portion 6) of the thermal expansion material 5, when the thermal expansion material 5 expands due to heat such as a fire, the filler 8 can suppress the thermal expansion material 5 from spreading outward, so that the thermal expansion material 5 easily expands inward and can surely close the gap between the pipe 1 and the sleeve 4.

[0034] Further, the thermal expansion material 5 is a member having thermal expansibility (the property of increasing in volume when heated) and fire resistance (the property of being resistant to heat, having a high melting temperature and being difficult to burn). As the thermal expansion material 5, those made of known materials can be used without particular limitation. For example, a paste-like member (a thermally expandable paste-like refractory material) can be used. Further, when the thermal expansion material 5 is heated to a predetermined temperature (for example, 200° C.) or higher, it expands in the thickness direction to fill the gap between the outer peripheral surface 1A of the pipe 1 and the inner peripheral surface 4B of the sleeve 4 shown in FIG. 5, thereby preventing the flame generated on one side of the partition through-hole 3 from moving to the other side of the partition through-hole 3.

[0035] The mounting member 7 is made of a synthetic resin material (it may also be a metal material), and is composed of two semi-circular frame members 11, 11. It is configured to be able to be externally mounted on the pipe 1 by joining the two semi-circular frame members 11, 11 in the radial direction. Each frame member 11 includes a pair of upper and lower frame portions 11A, 11A extending in an arc shape, a central connecting portion 11B connecting the central portions in the circumferential direction of the frame portions 11A, 11A in the vertical direction, and end connecting portions 11C, 11C connecting both ends in the circumferential direction of the frame portions 11A, 11A in the vertical direction. Rectangular openings 11K are respectively formed between the central connecting portion 11B and one end connecting portion 11C and between the central connecting portion 11B and the other end connecting portion 11C.

[0036] Also, on one end connecting portion 11C of each frame member 11, a U-shaped locked portion 11E for forming a locking hole 11e protrudes outward in the circumferential direction, and on the other end connecting portion 11C, a locking protrusion 11F that can be locked and unlocked to the locking hole 11e is formed. The locking hole 11e is configured in a vertically long rectangular shape, and the locking protrusion 11F that locks to the locking hole 11e is composed of a vertically long protrusion that protrudes radially from the surface of the other end connecting portion 11C. Therefore, by locking the locking protrusion 11F of the other frame member 11 facing this to the locking hole 11e of the locked portion 11E of one frame member 11, and locking the locking protrusion 11F of one frame member 11 to the locking hole 11e of the locked portion 11E of the other frame member 11 facing this, an annular mounting member 7 can be constituted.

[0037] Also, at the central portion in the circumferential direction of each frame member 11, there is provided a contact portion 12 that contacts the wall surface 2A (the upper floor surface 2A in the figure) on the side where the sleeve 4 is inserted in the partition body (floor 2) when the sleeve 4 is located at a predetermined position in the partition through hole 3.

[0038] The two abutting portions 12, 12 are arranged at positions facing each other in the radial direction. Each abutting portion 12 includes a plate-shaped finger abutting portion 12A against which a finger is pressed, and a horizontally long rectangular plate-shaped finger hanging portion 12B that protrudes downward from the lower surface of the finger abutting portion 12A and hooks another finger. The finger abutting portion 12A extends radially outward from the upper frame portion 11A and is configured in a substantially trapezoidal shape with a narrower width toward the extending end side. Also, the finger hanging portion 12B extends downward from the central portion in the width direction of the finger abutting portion 12A.

[0039] An operation of filling the gap between the pipe 1 and the partition through-hole 3 using the sleeve 4 with the flange portion 6 and the mounting member 7 configured as described above will be described.

[0040] On the floor surface 2A on the upper floor where the pipe 1 protruding upward from the partition through-hole 3 is located, the sleeve 4 with the flange portion 6 and the mounting member 7 are respectively put on, and the two ends are locked to each other as described above for exterior decoration (see FIGS. 2 and 3). After exterior decoration, by pushing downward with the mounting member 7 (see FIG. 3), the sleeve 4 with the flange portion 6 is pushed into the partition through-hole 3. When the flange portion 6 provided on the sleeve 4 abuts against the inner peripheral surface 3A of the partition through-hole 3, the flange portion 6 is deformed into the concave shape described above, and its tip portion enters the partition through-hole 3 together with the sleeve 4 while being in close contact with the inner peripheral surface 3A of the partition through-hole 3. Then, when the lower ends 12b, 12b of the finger hanging portions 12B, 12B of the abutting portions 12, 12 provided on the mounting member 7 abut against the floor surface 2A (see FIG. 4), the sleeve 4 is positioned at a predetermined installation position in the partition through-hole 3, the flange portion 6 is in a state of closing the partition through-hole 3, and the operation of pushing the sleeve 4 by the mounting member 7 is completed. After completion, the mounting member 7 is moved along the pipe 1 above the partition through-hole 3, or after removing the mounting member 7 from the pipe 1, the filling material 8 is filled into the partition through-hole 3 from the same side where the sleeve 4 is inserted, and the filling operation is completed (see FIG. 5).

[0041] As the filling material 8, in addition to using water-based acrylic resin-based, urethane resin-based, epoxy resin-based, silicone-based, etc., mortar or grout may also be used. In particular, by using a material with a viscosity lower than that of general-purpose construction sealing materials and excellent fluidity that is easy to fill in the partition through-hole 3, there is an advantage that it can be filled well even when the gap between the partition through-hole 3 and the pipe 1 is small.

[0042] FIG. 5 shows a state in which the filling material 8 is filled in the gap between the partition through-hole 3 and the pipe 1 when the sleeve 4 is inserted into the partition through-hole 3. Looking at FIG. 5, a water stop portion 13 is formed between the floor surface 2A at the front end in the insertion direction of the sleeve 4 in the partition through-hole 3 and the upper end surface 4C (the other end in the axial direction) of the sleeve 4 to prevent the water on the upper floor with the floor surface 2A from flowing downstairs through the partition through-hole 3. This water stop portion 13 is an area where only the filling material 8 can be filled without generating a gap for water to enter between the partition through-hole 3 and the pipe 1, and reliable water stop can be achieved. Also, in a state where the sleeve 4 is inserted into the partition through-hole 3, by positioning the filling material receiving portion (flange portion 6) on the front side in the insertion direction of the sleeve 4 rather than on the back side in the insertion direction of the sleeve 4 in the partition through-hole 3, a space where the flange portion 6 does not fall out of the partition through-hole 3, that is, a fall prevention clearance 14, is preferably set between the lower end surface 4D of the sleeve 4 and the lower end 3B of the partition through-hole 3. By forming the said space, the amount of the filling material 8 filled in the partition through-hole 3 can be reduced. <Second Embodiment>

[0043] In FIG. 6, the attachment member 7 is composed of a pair of pushing members 15, 15. Also, locking portions 16, 16 for locking and holding the pair of pushing members 15, 15 are provided at two positions (positions facing each other in the radial direction) at the upper end of the sleeve 4 described later.

[0044] Each pressing member 15 includes a pressing main body 15A having a plate-shaped horizontal portion 15a against which a finger is pressed and a plate-shaped vertical plate portion 15b extending downward from one end of the horizontal portion 15a in the horizontal direction (lateral direction), and a plate-shaped rectangular contact portion 15B that extends downward from the central portion in the width direction of the horizontal portion 15a and contacts the floor surface 2A on the side where the sleeve 4 is inserted in the partition body (floor 2) when the sleeve 4 is located at a predetermined installation position in the partition through hole 3.

[0045] Each locking portion 16 is composed of a pair of members 16A, 16A that extend upward from the upper end of the sleeve 4 and are substantially L-shaped in plan view, and the lower end portion of the vertical plate portion 15b of the pressing member 15 is inserted and locked between the pair of members 16A, 16A. Note that the locked vertical plate portion 15b can be unlocked by grasping the pressing member 15 and lifting it upward.

[0046] The sleeve 4 is configured to be insertable into the partition through hole 3 in a direction in which one axial end portion is on the front end side of the insertion direction and the other axial end portion is on the rear end side of the insertion direction, as described above. Further, the sleeve 4 is made of synthetic resin (metal may also be used), and is configured to be externally attachable to the pipe 1 by integrating two semi-circular members 17, 17 having the same configuration in plan view. At one circumferential end portion of each semi-circular member 17, a U-shaped locked portion 17A for forming a locking hole 17a projects outward in the circumferential direction, and at the other circumferential end portion, a locking protrusion 17B that can be locked and unlocked to the locking hole 17a is formed. The locking hole 17a is configured in a vertically long rectangular shape, and the locking protrusion 17B that locks to the locking hole 17a is composed of a protrusion that is vertically long and projects radially from the surface of the semi-circular member 17. Therefore, the sleeve 4 can be formed by locking the locking protrusion 17B at the other end portion of the other semi-circular member 17 facing this to the locking hole 17a at one end portion of one semi-circular member 17, and locking the locking protrusion 17B at the other end portion of one semi-circular member 17 to the locking hole 17a at one end portion of the other semi-circular member 17 facing this.

[0047] On the upper part of the outer surface of each split member 17, a number of protrusions 17T extending in the vertical direction at predetermined intervals in the circumferential direction are formed. These protrusions 17T are configured in an inverted triangular pyramid shape with the bottom surface positioned upward and the top positioned downward, and are for suppressing the sleeve 4 from passing through the partition through-hole 3 in the vertical direction. Also, the upper end portion of each split member 10 is slightly thicker than other parts and is adapted to abut against the lower end portion of the mounting member 7 in a surface-to-surface manner. Further, on the lower end portion of each split member 17, a pair of upper and lower ridges 17C for suppressing the vertical movement of the flange portion 6 are formed. The ridges 17C extend along the circumferential direction of the split member 17 and are formed over the entire circumferential area of the split member 17.

[0048] Also, on the inner surface of each split member 17, a thermal expansion material 5 having the same configuration as described above is provided. This thermal expansion material 5 has a circumferential dimension extending over the entire circumferential area of each split member 17 and has a dimension slightly smaller than the vertical dimension of each split member 17 so as not to protrude from the upper and lower ends of each split member 17. Further, the thermal expansion material 5 is disposed (recessed) inside the sleeve 4 so as to be disposed on the outer peripheral surface of the pipe 1, and is disposed toward the front side in the insertion direction of the sleeve 4 in a state where a part thereof overlaps with the flange portion 6 in the sleeve 4 in the radial direction with respect to the partition through-hole 3. By disposing the thermal expansion material 5 in this way, when the thermal expansion material 5 expands due to heat such as a fire in the portion on the front side in the insertion direction of the sleeve 4 rather than the filler receiving portion (flange portion 6) of the thermal expansion material 5, the expansion of the thermal expansion material 5 outward can be suppressed by the filler 8, so that the thermal expansion material 5 easily expands inward and can surely fill the gap between the pipe 1 and the sleeve 4.

[0049] An operation of filling the gap between the pipe 1 and the partition through-hole 3 using the sleeve 4 with the flange portion 6 and the mounting members 7, 7 configured as described above will be described.

[0050] On the upper floor with the bed surface 2A, the pipe 1 protruding upward from the partition through-hole 3 is externally covered by locking both ends while covering the sleeve 4 with a flange 6 as described above. The mounting members 7, 7 are respectively locked to the locking portions 16, 16 provided on the externally covered sleeve 4. Incidentally, after the mounting members 7, 7 are respectively locked to the locking portions 16, 16 provided on the sleeve 4, the sleeve 4 provided with the mounting members 7, 7 may be externally covered on the pipe 1. Subsequently, by pushing downward with the mounting members 7, 7 respectively, the sleeve 4 is pushed into the partition through-hole 3. When the outer peripheral portion of the flange 6 provided on the sleeve 4 comes into contact with the inner peripheral surface 3A of the partition through-hole 3, while the flange 6 becomes the above-described bowl shape, it enters the partition through-hole 3 together with the sleeve 4. Then, when the lower ends of the contact portions 15B, 15B of the mounting members 7, 7 come into contact with the bed surface 2A, the sleeve 4 is positioned at a predetermined installation position within the partition through-hole 3, the flange 6 is in a state of closing the partition through-hole 3, and the pushing operation of the sleeve 4 by the mounting members 7, 7 is completed. After completion, the mounting members 7, 7 are removed by unlocking them from the sleeve 4, and then the filling material 8 is filled into the partition through-hole 3 from the same side where the sleeve 4 is inserted, and the filling operation is completed. Incidentally, since the filling material 8 is the same as described above, the description thereof is omitted.

[0051] FIG. 8 shows a state in which the filling material 8 is filled in the gap between the partition through-hole 3 and the pipe 1 when the sleeve 4 is inserted into the partition through-hole 3. Looking at FIG. 8, the water stop portion 13 and the fall prevention clearance 14 are formed in the same manner as in FIG. 5. Therefore, the detailed description of the water stop portion 13 and the fall prevention clearance 14 is omitted. <Third Embodiment>

[0052] In FIGS. 9 to 11, the case where the above-described mounting member is integrated with the sleeve 4 (in this embodiment, it is integrally formed, but a separately formed mounting member may be non-removably attached to the sleeve by an adhesive or welding, etc.) is shown.

[0053] The attachment member 7 is composed of a pair of pushing members 18, 18 having the same shape and facing each other in the radial direction. Each pushing member 18 includes an arch-shaped main body 18A that is plate-shaped and has an opening 18K formed at the center, and a plate-shaped rectangular contact portion 18B that protrudes radially outward from the center in the width direction on the upper outer surface of the main body 18A and contacts the floor surface 2A on the side where the sleeve 4 is inserted in the partition body (floor 2) when the sleeve 4 is located at a predetermined installation position in the partition through-hole 3. The main body 18A is formed in an inclined posture where it is located radially outward toward the upper side, and a gap is formed between the inner surface 18a of the main body 18A and the outer peripheral surface 1A of the pipe 1 in a state where the sleeve 4 is externally mounted on the pipe 1. Further, since the filling material 8 passes through the opening 18K at the center in the width direction of the main body 18A (see FIG. 11), even when the filling material 8 is filled with a part of the main body 18A entering the partition through-hole 3, there is no problem in filling the filling material 8.

[0054] As described above, the sleeve 4 is configured to be insertable into the partition through-hole 3 with one axial end at the front end side in the insertion direction and the other axial end at the rear end side in the insertion direction. The sleeve 4 is made of synthetic resin (metal may also be used), and is configured to be externally mounted on the pipe 1 by integrating two semi-circular members 19, 19 having the same configuration in a plan view. At one circumferential end of each semi-circular member 19, a U-shaped locked portion 19A for forming a locking hole 19a protrudes outward in the circumferential direction, and at the other circumferential end, a locking protrusion 19B that can be locked and unlocked to the locking hole 19a is formed. The locking hole 19a is configured in a vertically long rectangular shape, and the locking protrusion 19B that locks to the locking hole 19a is composed of a protrusion that is vertically long and protrudes radially from the surface of the semi-circular member 19. Therefore, the sleeve 4 can be configured by locking the locking protrusion 19B at the other end of the other semi-circular member 19 facing this to the locking hole 19a at one end of one semi-circular member 19, and locking the locking protrusion 19B at the other end of one semi-circular member 19 to the locking hole 19a at one end of the other semi-circular member 19 facing this.

[0055] On the upper part of the outer surface of each split member 19, a number of protrusions 19T extending in the vertical direction at predetermined intervals in the circumferential direction are formed. These protrusions 19T are configured in a triangular prism shape with the bottom surface positioned upward and the top positioned downward, and are for suppressing the sleeve 4 from passing through the partition through-hole 3 in the vertical direction. Also, at the lower end of each split member 19, a pair of upper and lower ridges 19C for suppressing the vertical movement of the flange portion 6 are formed. The ridges 19C extend along the circumferential direction of the split member 19 and are formed over the entire circumferential area of the split member 19.

[0056] Further, on the inner surface of each split member 19, a thermal expansion material 5 having the same configuration as described above is provided. This thermal expansion material 5 has a circumferential dimension extending over the entire circumferential area of each split member 19 and has a dimension slightly smaller than the vertical dimension of each split member 19 so as not to protrude from the upper and lower ends of each split member 19. Also, the thermal expansion material 5 is arranged (recessed) inside the sleeve 4 so as to be disposed on the outer peripheral surface of the pipe 1, and is arranged toward the front side in the insertion direction of the sleeve 4 in a state where a part thereof overlaps the flange portion 6 in the sleeve 4 in the radial direction with respect to the partition through-hole 3. By arranging the thermal expansion material 5 in this way, when the thermal expansion material 5 expands due to heat such as a fire in the portion on the front side in the insertion direction of the sleeve 4 rather than the filler receiving portion (flange portion 6) of the thermal expansion material 5, the expansion of the thermal expansion material 5 outward can be suppressed by the filler 8, so that the thermal expansion material 5 easily expands inward and can surely close the gap between the pipe 1 and the sleeve 4.

[0057] The operation of filling the gap between the pipe 1 and the partition through-hole 3 using the sleeve 4 with the flange portion 6 and the mounting members 7, 7 configured as described above will be described.

[0058] On a floor above the bed surface 2A, the outer sides of both ends of the pipe 1 protruding upward from the partition through-hole 3 are covered with a sleeve 4 having a flange portion 6 and with attachment members 7, 7 integrally formed thereon, and are locked to each other as described above. Subsequently, by pushing downward with each of the attachment members 7, 7, the sleeve 4 is pushed into the partition through-hole 3. When the outer peripheral portion of the flange portion 6 provided on the sleeve 4 comes into contact with the inner peripheral surface 3A of the partition through-hole 3, while the flange portion 6 assumes the above-described bowl shape, it enters the partition through-hole 3 together with the sleeve 4. Then, when the lower ends of the contact portions 18B, 18B of the attachment members 7, 7 come into contact with the bed surface 2A, the sleeve 4 is positioned at a predetermined installation position within the partition through-hole 3, the flange portion 6 is in a state of closing the partition through-hole 3, and the operation of pushing in the sleeve 4 by the attachment members 7, 7 is completed. After completion, the filling material 8 is filled into the partition through-hole 3 from the same side where the sleeve 4 is inserted, and the filling operation is finished. Note that since the filling material 8 is the same as described above, the description thereof is omitted.

[0059] FIG. 11 shows a state in which the filling material 8 is filled in the gap between the partition through-hole 3 and the pipe 1 when the sleeve 4 is inserted into the partition through-hole 3. Looking at FIG. 11, a water stop portion 13 and a fall prevention clearance 14 are formed in the same manner as in FIG. 5. When filling the filling material 8 into the partition through-hole 3, as described above, the filling material 8 can be filled without any trouble, so that the water stop portion 13 can be reliably formed. Note that since the configurations not described are the same as those described above, the detailed descriptions thereof are omitted. <Fourth Embodiment>

[0060] In FIGS. 14 to 19, as in FIGS. 9 to 11, a case is shown where the attachment member 7 is integrated with the sleeve 4 (in this embodiment, it is integrally formed, but a separately formed attachment member may be non-removably attached to the sleeve by an adhesive, welding, or the like).

[0061] The mounting member 7 is composed of two pairs of identical-shaped pushing members 20, 20, 20, 20 arranged at 90-degree intervals in the circumferential direction so as to face each other in the radial direction on the upper end surface 4C of the sleeve 4. Each pushing member 20 includes a main body portion 20A extending straight upward from the upper end surface 4C of the sleeve 4, and a substantially rectangular plate-shaped finger abutting portion 20B protruding radially outward from the upper end of the main body portion 20A for abutting a finger. The main body portion 20A is configured in an arc-shaped plate shape in a plan view along the circumferential direction from the inner peripheral edge of the upper end surface 4C of the sleeve 4. Further, a reinforcing vertical rib 20R protruding radially outward and extending in the vertical direction is formed at the central portion in the circumferential direction of the outer surface of the main body portion 20A. The lower end of the vertical rib 20R is connected to the upper end surface 4C of the sleeve 4, and the upper end thereof is connected to the lower end of the finger abutting portion 20B. In this embodiment, the pushing members 20, 20, 20, 20 and the sleeve 4 are integrally formed of a synthetic resin, but they may be formed of metal or other materials having shape retention properties.

[0062] The sleeve 4 is configured to be insertable into the partition through hole 3 in a direction in which one axial end portion is on the front end side in the insertion direction and the other axial end portion is on the rear end side in the insertion direction, as described above. Further, the sleeve 4 is made of synthetic resin (or metal), and has a plurality (two in this embodiment) of members 21, 21 arranged in a cylindrical shape (cylindrical in this embodiment, but may be square cylindrical) in the circumferential direction. One of the end portions facing each other in the circumferential direction of the plurality of members 21, 21 is openable and closable, and the rest are connected via a thin connecting portion 22 rotatable so as to open and close the one. Therefore, by opening one of the end portions facing each other in the circumferential direction of the plurality of members 21, 21 in the circumferential direction, the sleeve 4 can be easily externally mounted on the pipe 1 from the side.

[0063] The two members 21, 21 are both configured in a semi-circular shape in plan view. At substantially the central portion in the vertical direction of the outer surface of each member 21, protrusions 21A that protrude radially outward and are long in the circumferential direction are respectively formed at the front and rear end portions in the circumferential direction. By having the protrusions 21A, 21A bite into the filler 8 that is filled and solidified, it is possible to prevent the sleeve 4 from coming off in the vertical direction from the partition through-hole 3. Further, as shown in FIG. 15, each member 21 is provided with an inner edge portion 21D that extends horizontally inward from the upper end, and an outer edge portion 21E that extends horizontally outward from the lower end of each member 21.

[0064] As shown in FIG. 14, the connecting portion 22 is composed of a thin-walled portion that is thinner than the two members 21, 21, and the two members 21, 21 are configured to be openable and closable in the circumferential direction via this connecting portion 22. One of the opening and closing end portions of the two members 21, 21 is provided with a locked portion 23, and the other is provided with a locking portion 24 that can be locked to and unlocked from the locked portion 23. The locked portion 23 is integrally formed on the outer surface of the opening and closing end portion of one member 21, and is composed of a rectangular frame member 23A in which a pair of vertically long rectangular long holes 23a, 23a are formed in the vertical direction. The locking portion 24 is integrally formed on the outer surface of the opening and closing end portion of the other member 21 so as to be locked in the circumferential direction to the long holes 23a, 23a, and is composed of a pair of vertically long and triangular protrusions 24A, 24A that protrude radially outward and are triangular in plan view. In this embodiment, the connecting portion 22 is composed of a thin-walled portion that is thinner than the two members 21, 21, but a connecting portion that rotatably connects the two members 21, 21 by a shaft extending in the vertical direction may be configured.

[0065] At a plurality of circumferential positions at one axial end (the lower end in FIG. 14) of the two members 21, 21, arc-shaped claw portions 25 protruding downward and extending along the circumferential direction in plan view are integrally formed. By inserting these claw portions 25 into a plurality (the same number as the claw portions 25) of arc-shaped slits 6S formed along the circumferential direction in the flange portion 6 in plan view, the flange portion 6 and the two members 21, 21 can be integrated. Incidentally, in a state where the claw portions 25 are inserted into the slits 6S, the tip portions (lower end portions) of the claw portions 25 may or may not protrude downward from the flange portion 6. In this embodiment, the claw portions 25 are configured to be detachable from the slits 6S, but the claw portions 25 may be fixed to the slits 6S using an adhesive or the like. By configuring an insertion type including the claw portions 25 and the slits 6S, the flange portion 6 protrudes radially outward from the outer peripheral surface of the sleeve 4.

[0066] The flange portion 6 has a cut 6H at one circumferential position, and this cut 6H is formed at substantially the same circumferential position (including the same position) as the opening / closing end positions 21S of the adjacent end portions 21B, 21C in the circumferential direction of the two members 21, 21 configured to be openable / closable (in FIG. 14, the end portions 21B, 21CB are slightly open, but are in a closed position). By forming the cut 6H in this way, the sleeve 4 and the flange portion 6 can be opened from the same circumferential position, and the sleeve 4 and the flange portion 6 can be simultaneously externally mounted on the pipe 1 from the side. The cut 6H includes a first portion that cuts radially inward from the outer peripheral edge of the flange portion 6, a second portion that cuts inward in a direction intersecting the radial direction from the inner end of the first portion, and a third portion that cuts radially inward from the inner end of the second portion toward the inner peripheral edge of the flange portion 6. That is, the first portion is formed at substantially the same circumferential position as the opening / closing end position 21S, and the other second portion and third portion are slightly offset from the opening / closing end position 21S in the circumferential direction, but may be configured to cut linearly in the radial direction so as to be formed at the same circumferential position as the opening / closing end position 21S, and the cut 6H may have any shape. As described above, with respect to the first portion that cuts radially inward from the outer peripheral edge of the flange portion 6, the other second portion and third portion are slightly offset from the opening / closing end position 21S in the circumferential direction, which has the effect of making it difficult for a gap to form between the mating surfaces of the cut 6H.

[0067] Also, on the inner surface of each member 21, there is provided a single heat expansion material 5 (made of the same material as described above) formed in a circular shape and rounded, and this heat expansion material 5 has a circumferential dimension that extends over the entire circumferential direction of the two members 21, 21, and has a dimension slightly smaller than the vertical dimension of the members 21, 21 so as not to protrude from the upper and lower ends of the members 21, 21. Further, on the inner surface of the heat expansion material 5, a single elastic member 26 formed in a circular shape and rounded, having substantially the same size as the heat expansion material 5 and deformable in a recoverable manner, is fixed by an adhesive or the like. This elastic member 26 is provided for quickly moving the sleeve 4 externally mounted on the pipe 1 into the partition through-hole 3, and although a sponge with low movement resistance is optimal, it may also be a soft rubber, a foamed material such as foamed polyurethane, or the like. Incidentally, the elastic member 26 is not necessarily required and can also be omitted.

[0068] The operation of filling the gap between the pipe 1 and the partition through-hole 3 using the sleeve 4 with the flange portion 6 and the pushing members 20, 20, 20, 20 configured as described above will be described.

[0069] On a floor above the bed surface 2A, the locking between the locking portion 24 and the locked portion 23 at the open end of the sleeve 4 having a flange portion 6 and integrally formed with the pushing members 20, 20, 20, 20 is released to open the sleeve 4 (see Fig. 15). At this time, the flange portion 6 is also released from the same position as the open end position of the sleeve 4. In this open state, the sleeve 4 and the flange portion 6 are put on the pipe 1 from the side. After covering, the locking portion 24 and the locked portion 23 at the open end of the sleeve 4 are locked to hold the sleeve 4 in a closed state (see Fig. 16). Subsequently, by pushing downward with any number (for example, two) of the pushing members 20, 20, 20, 20 among the pushing members 20, 20, 20, 20, the sleeve 4 is pushed into the partition through hole 3. When the outer peripheral portion of the flange portion 6 provided on the sleeve 4 comes into contact with the inner peripheral surface 3A of the partition through hole 3, while the flange portion 6 becomes the above-described bowl shape, it enters the partition through hole 3 together with the sleeve 4. Then, the sleeve 4 is pushed into the partition through hole 3 until the upper ends of the pushing members 20, 20, 20, 20 reach a predetermined installation position substantially at the same height as the bed surface 2A. When the sleeve 4 is located at a predetermined installation position in the partition through hole 3, the flange portion 6 closes the partition through hole 3, and the pushing operation of the sleeve 4 is completed (see Fig. 17). After completion, the filling material 8 is filled into the partition through hole 3 from the same side where the sleeve 4 is inserted, and the filling operation is completed (see Figs. 18 and 19). Note that since the filling material 8 is the same as described above, the description thereof is omitted.

[0070] Fig. 19 shows a state in which the filling material 8 is filled in the gap between the partition through hole 3 and the pipe 1 when the sleeve 4 is inserted into the partition through hole 3. Looking at Fig. 19, the water stop portion 13 and the fall prevention clearance 14 are formed in the same manner as in Fig. 5. When filling the filling material 8 into the partition through hole 3, since the pushing members 20, 20, 20, 20 are arranged only at four circumferential positions at the upper end of the sleeve 4, the filling material 8 can be filled without any trouble. Therefore, the water stop portion 13 can be surely formed. Note that the configurations not described are the same as those described above, and thus the detailed descriptions thereof are omitted.

[0071] Furthermore, the present invention is not limited to the above four embodiments, and various modifications can be made without departing from the gist of the present invention.

[0072] In the fourth embodiment, the cut 6H is formed at a position substantially the same as (including the same position) the opening / closing end positions 21S of the two openable ends 21B and 21C in the circumferential direction. However, the cut 6H may be formed at a position different from the opening / closing end positions 21S of the two openable ends 21B and 21C in the circumferential direction.

[0073] In the first to third embodiments, the two half members are integrated by locking both ends thereof to form the sleeve 4. However, the two members may be connected to be rotatable relative to each other about one end, and a lockable portion and a locking portion that can be unlocked may be provided at the other ends of the two members, respectively. Further, the sleeve may be formed of an annular member having one end configured to be openable by an elastic body, or a flexible flat plate material, a corrugated material, or the like.

[0074] In the above four embodiments, the floor is taken as an example, but the wall may be taken as an example. In the case of a wall, wall surfaces exist at both ends of the partition through hole.

[0075] In the above four embodiments, the case where the mounting member is used is shown, but the mounting member may be omitted and the sleeve may be directly pushed into the partition through hole.

[0076] In the above four embodiments, the partition through hole 3 is circular in plan view, but it may be rectangular in plan view. At this time, the shape of the flange portion 6 is also rectangular in plan view.

[0077] Also, in the three embodiments of the first to third embodiments, the thermal expansion material 5 is arranged toward the front side in the insertion direction of the sleeve 4 in a state where a part thereof overlaps with the flange portion 6 in the sleeve 4 in the radial direction in the partition through-hole 3. However, the thermal expansion material 5 may be arranged on the front side (rear end side) in the insertion direction of the sleeve 4 rather than the flange portion 6 so that a part thereof does not overlap with the flange portion 6 in the sleeve 4 in the radial direction in the partition through-hole 3. Further, as shown in FIG. 12, the thermal expansion material 5 may be arranged so as to substantially completely overlap with the flange portion 6 in the radial direction. In this case, a protruding portion 4T protruding outward is formed in the middle portion in the insertion direction of the sleeve 4, and the thermal expansion material 5 is arranged inside the protruding portion 4T. Further, as shown in FIG. 13, the thermal expansion material 5 may be arranged at the end portion on the back side in the insertion direction of the sleeve 4 rather than the flange portion 6 so as not to overlap with the flange portion 6 in the radial direction. In this case, a protruding portion 4T protruding outward is formed at the end portion on the back side in the insertion direction of the sleeve 4, and the thermal expansion material 5 is arranged inside the protruding portion 4T. In FIG. 19 of the fourth embodiment, since the flange portion 6 is inserted into and held by the claw extending downward from the lower end of the sleeve 4, the thermal expansion material 5 is located on the front side in the insertion direction of the sleeve 4 rather than the flange portion 6. Note that the parts not described in FIGS. 12 and 13 have the same configuration as that in FIG. 5, and thus the same reference numerals as those in FIG. 5 are given and the description thereof is omitted. Further, although the thermal expansion material 5 is arranged on the inner surface of the sleeve 4, the thermal expansion material 5 may not be arranged on the sleeve 4, and the thermal expansion material 5 may be arranged on the outer peripheral surface of the pipe 1 and then the sleeve 4 may be inserted into the partition through-hole 3. Further, a measure tool omitting the thermal expansion material 5 may be used.

[0078] Also, in the fourth embodiment, the sleeve 4 includes two members 21, 21, but it may include any number of three or more members. In this case, one of the end portions facing each other in the circumferential direction among the three or more members is openable and closable, and the remaining two or more are connected via a connecting portion rotatable so that the one opens and closes.
