DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a split seat packing and a hole filling structure used for filling a hole in a floor penetrating portion in which pipes such as a water supply pipe, a hot water supply pipe and a drain pipe are inserted into a through hole formed in a floor of a building. .

2. Description of the Related Art As is well known, in a floor penetrating portion where a pipe material such as a water supply pipe is inserted into a through hole formed in a floor of a building with a gap, for example, heat insulating material is inserted into the gap and coking finish is performed. In some cases, the pipes are filled with holes, etc., but the pipes are often left as they are without being filled after the piping work of the pipe material. In such a case, the holes are filled using an arm seat or a plastic split seat.

[0003]

However, in the prior art as described above, since the through holes are formed by construction work and their shapes and dimensions are not constant, it is very difficult to fill the holes with the heat insulating material or the like. Is complicated. In addition, whether or not to perform the filling with the heat insulating material or the like is based on the determination of the worker who performed the plumbing work, since the filling may not be performed with the heat insulating material as described above,
There is a problem that it is not possible to unify hole filling work.

Further, when the above-mentioned heat insulating material or armrest is used, the pipe material directly contacts the through hole, or when the above-mentioned arm seat or plastic split seat is used, the pipe material is formed in the through hole or floor. Since the contact is made via the arm seat or the like, there is a problem that the sound of water flowing in the pipe material is transmitted to the floor to generate piping noise.

[0005] In addition, when the armrest or the plastic cotter is used, the airtightness between the armrest and the pipe and the floor surface is not so high. There is also a problem that the water leaks from the floor to the floor where it is difficult to detect the water leak.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is possible to easily and unify the filling operation even if the shape and dimensions of the through-hole in the floor penetration portion are not constant. It is an object of the present invention to provide a split seat packing and a hole filling structure of a floor penetrating portion that can be performed and that can prevent piping noise and water leakage below the floor.

And an annular cushioning member protruding in a direction perpendicular to the direction.

A fitting portion is formed at one circumferential end of the cylindrical portion and the annular cushioning member, and a fitting portion fitted to the fitting portion at the other end. Respectively.

[0009] Further, the means for filling the through hole in the floor penetrating portion is that in the hole filling structure of the floor penetrating portion in which a pipe material is inserted with a gap in a through hole formed in the floor of the building, the cross section is substantially C-shaped. And a splitter-type cylindrical portion including a cylindrical core material formed so as to be elastically openable and closable and a cylindrical cushioning material attached to an inner peripheral surface of the cylindrical core material, and an outer periphery of the splitter-type cylindrical portion The above-mentioned cotter-type cylindrical portion of the cotter packing of the floor penetrating portion provided with an annular cushioning material projecting in a direction perpendicular to the length direction of the cotter-type cylindrical portion on the surface, The present invention is characterized in that the annular cushioning material is adhered to the floor surface so as to be fitted in a closed state while being externally fitted, and the closed annular cushioning material is closed following the split-shaped cylindrical portion so as to close the gap.

[0010] A fitting portion is formed at one circumferential end of each of the split type cylindrical portion and the annular cushioning material, and a fitting portion fitted to the fitting portion at the other end. Respectively.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1 to FIG.
In the floor penetration portion A according to the embodiment, a pipe material 3 is inserted in a circular through hole 2 formed in a floor 1 of a building in a direction perpendicular to the floor surface 1a with a gap 4 opened.

The hole filling structure of the floor penetration portion A is a split-seat cylindrical portion 1 composed of a cylindrical core material 11 and a cylindrical cushioning material 12.
3 and the split-type cylindrical portion 13 of the split seat packing 21 provided with an annular cushioning material 14 protruding from the outer peripheral surface 13b of the split-type cylindrical portion 13. A floor surface is inserted into the through hole 2 from above and adhered in a closed state, and the closed annular cushioning material 14 is closed following the split-seat cylindrical portion 13 so as to close the gap 4. 1a.

The cotter type cylindrical portion 13 is shown in FIGS.
And a cylindrical core member 11 having a substantially C-shaped cross section and capable of elastically opening and closing, and an inner peripheral surface 11 a of the cylindrical core member 11.
And a cylindrical cushioning material 12 affixed thereto.

The cylindrical core member 11 is formed of, for example, a hard or semi-hard plastic, metal, or the like into a cylindrical shape having a substantially C-shaped cross section, and can be elastically opened and closed by its elastic force. The cylindrical core member 11 may be formed in a closed state as shown in FIGS. 3 and 4 or in a partially opened state as shown in FIG. 2 according to the elastic modulus of the material. May be formed. In short, it is only required that the cotter type cylindrical portion 13 having the cylindrical core material 11 can be opened when externally fitted to the tube material 3 from the side, and can be closed after externally fitted to the tube material 3.

The cylindrical cushioning material 12 is adhered to the entire inner peripheral surface 11a of the cylindrical core material 11 as necessary with an adhesive or the like, and is made of, for example, a cushioning material (buffer) such as soft rubber, soft plastic foam, or foamed rubber. ) And is soft, so that it can be elastically opened and closed following the cylindrical core material 11. Then, as shown in FIG. 2, the split-type cylindrical portion 13 is externally fitted to the tube 3 from the side, and then, in a closed state as shown in FIG. 3 and FIG. Glued.

In the case where the circumferential end portions 13c and 13d of the cylindrical portion 13 are closed by abutting each other as in this embodiment, the cylindrical portion 13 may be closed. May be formed to be substantially the same as the outer diameter of the tube 3. Further, it is desirable to apply an adhesive or the like to the abutting portion between the end portions 13c and 13d in advance or after closing the split seat type cylindrical portion 13 in order to further improve airtightness. Further, the cylindrical buffer material 12 is not required to flow down from between the pipe material 3 and the cylindrical buffer material 12 when water leaks from the pipe material 3. If it is formed along the circumferential direction of the surface 11a, its length may be shorter than the cylindrical core material 11.

The annular cushioning member 14 is provided in the split-seat cylindrical portion 1.
3 on the outer peripheral surface 13b as required.
Is integrally formed with the cylindrical cushioning member 12 via a connecting portion 15 covering the vicinity of the upper edge, and protrudes in a direction perpendicular to the length direction of the split type cylindrical portion 13. Since it is made of a material having a cushioning property and is soft, it is elastically openable and closable following the split type cylindrical portion 13. Then, as shown in FIGS. 1, 3 and 4, an adhesive or a screw 16 is attached to the floor 1a so as to close the gap 4 in a closed state.
And the like, or a combination thereof. When the screw 16 is used, the circumferential end 14 of the annular cushioning material 14 is used.
It is desirable to screw a plurality of places including around c and 14d.

In this embodiment, the circumferential end portions 14c and 14d of the annular cushioning member 14 are closed by abutting each other. However, the present invention is not limited to this. At least one end portion is provided. 14c (14d) is protruded by a predetermined length in the circumferential direction of the split-type cylindrical portion 13, and the ends 14c and 14d are closed so as to overlap each other, and this overlapped portion is screwed to the floor surface 1a. And so on. As in the case of the split type cylindrical portion 13, it is desirable to apply an adhesive or the like to the butted portion or the overlapped portion in order to increase airtightness. Further, the projecting location of the annular cushioning member 14 is not limited to the middle portion in the length direction of the split seat type cylindrical portion 13 but may project from the upper edge or the lower edge thereof.

As described above, by using the above-mentioned cotter packing 21, the cotter-type cylindrical portion 13 is adhered to the pipe member 3 in a closed state, and the annular cushioning member 14 is also closed in the floor surface. Since it is adhered to 1a, even if there is a water leak from the pipe material 3, the leaked water flows out to the floor surface 1a without flowing down the floor. Therefore, there is an advantage that it is easy to find a water leak and the damage is minimized. Further, in addition to the case where the cotter type cylindrical portion 13 is not in contact with the through hole 2 and the case where they are in contact, the pipe material 3 and the floor
Since the cylindrical cushioning material 12 and the annular cushioning material 14 are adhered to a, the sound of water flowing in the pipe material 3 is absorbed by these cushioning properties and is hardly transmitted to the floor 1,
Therefore, piping noise can be reliably prevented.

Since the annular cushioning member 14 protrudes a predetermined length from the outer peripheral surface 13b of the split-cylinder cylindrical portion 13, if the projecting length is relatively large, the through hole 2 can be formed. Can be adequately dealt with even when the size becomes large or when the shape becomes a rectangular shape as shown in FIG. 5, for example. Therefore, if the split packing 21 configured as described above is prepared, even if the shape and the size of the through hole 2 are not constant, it is possible to fill the floor penetration portion A and unify the filling operation. Can also be achieved.

As shown in FIG. 6 and FIG. 7, the hole filling structure of the floor penetrating portion A according to the second embodiment differs from the first embodiment in the circumferential direction of the split-seat cylindrical portion 13 and the annular cushioning material 14. A split seat packing 31 is used, in which fitting portions 22 are formed at one end portions 13c and 14c, respectively, and fitting portions 23 fitted to the fitting portions 22 are formed at the other end portions 13d and 14d. It was what was.

The fitting portion 22 is formed, for example, in the form of a paragraph at one end portions 13c and 14c in the circumferential direction of the split type cylindrical portion 13 and the annular cushioning material 14, respectively. The fitted portion 23 includes a split-type cylindrical portion 13 and an annular cushioning material 1.
For example, each of the other end portions 13d and 14d in the circumferential direction of 4 is formed in a convex shape, and can be fitted to the fitting portion 22 respectively. The shape of the fitting portion 22 and the fitted portion 23 is not limited to a paragraph shape or a convex shape, and various shapes that can be fitted to each other can be adopted.

By using the split packing 31 constructed as described above, as shown in FIG.
3 can be attached to the tube 3 by closing the split-type cylindrical portion 13 and the annular cushioning material 14 even when the tube 3 is slightly loosened from the completely fitted state. There is an advantage that it can sufficiently cope with different cases. As described above, when the fitting portion 22 and the fitted portion 23 are attached in a slightly loosened state without being completely fitted, a gap is formed between the closed portion of the split type cylindrical portion 13. When 24 is formed, it is desirable to fill the gap 24 with an adhesive or the like so that water leakage from the pipe material 3 does not flow below the floor. Further, similarly to the first embodiment, the floor surface 1 of the annular cushioning material 14 is used.
In the case where the screw 16 is used for bonding to the portion a, it is desirable to screw a plurality of portions of the annular cushioning member 14 including the overlapping portion between the fitting portion 22 and the fitted portion 23.

Further, in the first and second embodiments, as shown by the phantom line in FIG. 6, the tightening belt 32 may be provided at a predetermined position on the outer peripheral surface 13b of the split-type cylindrical portion 13 as necessary. If a tightening member such as is attached and the split member type cylindrical portion 13 can be tightened to the pipe member 3 by this tightening member, there is an advantage that the split seat packings 21 and 31 can be more firmly attached.

[0025]

As described above, according to the first aspect of the present invention, even when the shape and size of the through hole are not constant, the filling of the floor penetration portion can be simplified and the filling operation can be unified. There is an advantage that there is.

According to the second and fourth aspects of the present invention, even if the fitting portion and the fitted portion are slightly loosened from a completely fitted state, the split-seated cylindrical portion and the annular Since it is possible to close the cushioning material and attach it to the pipe, there is an advantage that even when the outer diameter of the pipe is slightly different, it can sufficiently cope with it.

According to the third aspect of the present invention, the split type cylindrical portion of the split packing is bonded to the pipe in a closed state, and the annular cushioning material is bonded to the floor in a closed state. Therefore, even if water leaks from the pipe material, the water leaks out to the floor without flowing down the floor, so that there is an advantage that the water leak can be easily found and the damage can be minimized. Further, in addition to the case where the split-type cylindrical portion is not in contact with the through hole, even in the case where they are in contact with each other, the cylindrical cushioning material or the annular cushioning material is bonded to the pipe material or the floor surface. Because of these cushioning properties, the sound of water flowing through the pipe is absorbed and hardly reaches the floor,
Therefore, there is also an advantage that pipe noise can be reliably prevented.
