Description

[0001]
[Industrial applications]
The present invention relates to a method of filling a gap formed between a pipe inserted into a through-hole provided in a partition section formed of a ceiling, a floor, and the like of a building with a filler. The present invention relates to a filling method capable of filling the gap formed between the pipe with the filler very easily and surely and preventing solid sound due to drainage of the pipe from being transmitted to the partition.
[0002]
[Prior art]
As shown in FIG. 5, for example, as shown in FIG. 5, a conventional pipe through-hole structure of this type has a through-hole 2 formed at a predetermined position of a partition 1 made of a floor, and a pipe 3 is inserted into the through-hole 2 so as to penetrate. The gap 4 formed between the hole 2 and the pipe 3 is filled with a filler 5. As the filler 5, a cement-based material such as mortar or a non-combustible fiber material such as rock wool has been used. Further, the gap 4 formed between the through hole 2 and the pipe 3 needs to be completely sealed and closed for fire prevention.
[0003]
[Problems to be solved by the invention]
However, in the case of the above-described conventional example, as described above, the filler 5 of the cement-based material such as mortar is firmly packed between the through hole 2 and the pipe 3 to harden this portion. The solid noise due to the drainage passing through the pipe 3 is transmitted to the partition 1 around the pipe 3, causing a problem of noise. Furthermore, when a cement-based material is used as the filler 5, it is necessary to remove the filler 5 with water and push it into the gap 4 with a trowel or work to prevent leakage. There was a very bad problem. In addition, when a non-combustible fiber material is used as the filler 5, it is difficult to uniformly fill the gap 4 with the filler 5, and it is determined whether the gap 4 is completely filled. There was a problem that was difficult to confirm.
[0004]
The present invention is a completely new technique developed in view of the above-mentioned conventional problems, and is particularly simple and reliable in filling a gap between a through hole of a partition portion and a pipe formed between the through holes. It is an object of the present invention to provide a technique of a filling method of a filler in which solid noise caused by drainage passing through a pipe is not transmitted to a partition around the pipe to generate noise.
[0005]
[Means for Solving the Problems]
The gist of the method of filling a pipe penetration portion according to the present invention is that a predetermined portion corresponding to a diameter of a pipe to be inserted into a predetermined position of a partition portion of a building including a main portion and a surface layer formed on the surface of the main portion. A through-hole with a diameter of is formed in advance by punching and is a filler made of an incombustible fibrous material that is an elastic filler, a cover film is laminated on the front surface, and an adhesive layer is provided on the back surface. Or, in accordance with the thickness of the gap and the partition formed when the pipe is inserted through the through hole with the filler formed in a tape shape, after previously wound around the outer circumference of the pipe and adhesively fixed, the pipe is By passing the filler through the main part of the partition part by passing through the through hole and continuing to the surface layer part, the pipe and the partition part are insulated without contacting each other, and the pipe and the through hole Non-combustible fiber over the entire gap formed between A method for filling a pipe penetration part, characterized in that filling and sealing the timber.
[0006]
[Action]
In the filling method of the pipe penetration portion of the present application, a filler made of a non-combustible fiber material formed in a sheet shape or a tape shape provided with an adhesive layer on one side, an outer peripheral portion of the pipe inserted into the through hole of the partition portion. It can be easily wound, adhered and fixed. By inserting a pipe having a filler adhered and fixed to the outer peripheral portion through a through-hole formed in the partition, the filling of the filler into the through-hole can be performed in the same manner as the insertion of the pipe into the through-hole. In particular, since the filler is adhesively fixed to the outer periphery of the pipe in accordance with the thickness of the partition, the filler is adhesively fixed to the outer circumference, and the filler is inserted into the through-hole, so that the filler is inserted into the main part of the partition. And can be continued to the surface layer. Therefore, the through hole formed in the partition portion is filled with the filler over the entire width in the thickness direction, and the pipe and the partition portion do not come into direct contact with each other.
[0007]
Since the noncombustible fiber material has elasticity, the gap formed between the through hole of the partition and the pipe can be buried uniformly and effectively as a whole. Further, it is possible to prevent the solid sound of the drainage passing through the pipe from being transmitted to the partition. Further, the gap between the through-hole and the pipe can be reliably sealed at a uniform density and without any unfilled portion by the filler wound around and fixed to the pipe. Since the filler has elasticity, even if the filler is slightly wound around the pipe, the pipe and the filler around the pipe can be inserted and filled into the through hole.

【Example】
FIG. 1 is a cross-sectional view illustrating an example of a filler according to the present invention. FIG. 1 is a cross-sectional view illustrating an example of a filler according to the present invention. 4 (A) and 4 (B) are cross-sectional views each showing a state in which a filler is wound around a pipe, FIG. 3 is a cross-sectional explanatory view showing the structure of a pipe penetration portion to which the filling method of the present invention is applied, and FIGS. 4) and 4 (C) are perspective explanatory views showing a procedure of the filling method of the present invention.
[0009]
In FIG. 1, reference numeral 11 denotes a filler for a sheet material, which is formed to have a predetermined width and length. The filler 11 is formed by integrally laminating a cover film 13 made of a polyester non-woven fabric or a polyester film on the lower surface (surface) of an elastic non-combustible fiber material 12 made of rock wool, ceramic fiber, or the like. An adhesive layer 14 and a release sheet 15 are sequentially laminated on the upper surface (back surface) of the fiber material 12.
[0010]
As described above, the purpose of laminating the cover film 13 on the surface of the non-combustible fiber material 12 is to prevent the non-combustible fiber material 12 from scratching. The reason why the adhesive layer 14 is provided on the back surface of the noncombustible fiber material 12 is that the filler 11 can be easily and reliably stuck and fixed around a pipe described later. In the above-described embodiment, the dimensions of the filler 11 are 125 mm in width, 600 mm in length, and 5 mm in thickness, but the width can be determined according to the thickness of a partition portion described later. . The length and the thickness are determined by a gap between a pipe to be described later and a through hole of the partition.
[0011]
FIG. 2A shows a configuration in which the above-described filler 11 is wound around the pipe 16 only one round so as to be single. FIG. 2B shows a configuration in which the filler 11 is wound around the pipe 16 twice so as to be doubled. In this manner, the thickness of the filler 11 can be adjusted by increasing or decreasing the number of windings in accordance with the gap formed between the through hole of the partition portion described later and the pipe 16. When the gap between the through hole 18 and the pipe 16 has a radius of 10 mm, the filler 11 having a thickness of 5 mm is wound around the circumference two times. If the radius of the pipe 16 is 90 mm, the length of the filler 11 is about 600 mm when the filler 11 having a thickness of 5 mm is wound around two times. Since the adhesive layer 14 is provided on the back surface of the filler 11 as described above, the filler 11 can be wound around the pipe 16 and fixed by peeling off the release sheet 15. In addition, the fillers 11 to be stacked can be fixed to each other.
[0012]
In FIG. 3, reference numeral 17 denotes a partition section composed of a floor, which is composed of a main section composed of a floor slab in the thickness direction and a surface layer section such as a finishing mortar constructed on the surface of the main section. . At a predetermined position of the partition portion 17, a through hole 18 through which the pipe 16 is inserted is formed. A gap 19 is formed between the pipe 16 and the through hole 18. The gap 19 is completely sealed by the filler 11 wound around the pipe 16 as described above. Therefore, the gap 19 between the through hole 18 and the pipe 16 can be completely sealed with the filler 11 to maintain airtightness, and a fireproof structure having heat resistance and fire resistance can be provided.
[0013]
When the pipe penetrating portion is constructed, for example, as shown in FIGS. 4A, 4B, and 4C, the peeling sheet 15 of the filler 11 is peeled while the filler 11 is removed from the outer peripheral surface of the pipe 16 at a predetermined position. And fixed by the adhesive layer 14. By pulling down the pipe 16 in this state, the pipe 16 and the filler 11 wound around the pipe 16 are simultaneously inserted into the through-hole 18, and formed by the through-hole 18 and the pipe 16 simultaneously with the connection and assembly of the pipe 16. The gap 19 to be formed can be sealed with the filler 11. In the figure, reference numeral 20 denotes a lower pipe, which has a structure connectable to the pipe 16.
[0014]
As described above, in the present invention, since the filler 11 is formed of a sheet material or a tape material, the filler material 11 can be simply and reliably wound around the pipe 16 and used. The width of the filler 1 can be determined according to the depth of the through hole 18 of the partition 17. The length of the filler 11 can be set in advance to a length to be used once, or an endless material can be cut to a required length and used each time.
[0015]
By providing the adhesive layer 14 on the filler 11 in advance, the filler 11 can be fixed to the pipe 16 as it is, and the filler 11 wound in multiple layers can be adhered and fixed to each other. Furthermore, when the filler 11 formed with a small thickness (for example, about 5 mm) is wound around the pipe 16 in multiple layers, it is flexible and easy to wind, and the cutting process in the middle is easy. Moreover, the gap 19 between the pipe 16 and the through hole 18 can be reliably sealed and closed.
[0016]
