Description

The present invention relates to a compartment penetration treatment filling member, a compartment penetration treatment structure, and a construction method of a division penetration treatment structure used for partitions of buildings and the like.

2. Description of the Related Art In buildings such as housing complexes, office buildings, and schools, partitions such as walls are sometimes provided with compartment penetration parts for passing long objects such as cables and piping. In order to prevent the spread of fire to other compartments when a fire breaks out in one of the compartments, the compartment penetration part is required to have a structure with fire prevention measures (fireproof structure). The partition is generally made up of two walls, each having a hollow space between the walls.

A method for making the compartment penetration part fireproof is, for example, filling the gap between the elongated insertion body and the through hole with an amorphous filler such as fireproof putty or a fireproof pack filled with fireproof putty inside a bag. It has been known. When using an irregularly shaped filler, a cylindrical member made of a fireproof material may also be provided between the inside of the through hole of each wall portion and the insertion body (for example, Patent Document 1, (see 2).

However, as shown in Patent Document 1, when the space between the inner circumferential surface of the through hole in each wall and the insertion body is closed with fireproof putty, the workability is poor and the performance varies depending on the operator. There's a problem. When the fireproof pack shown in Patent Document 2 is used, workability is improved, but the volume of the amorphous filler remains constant, and depending on the size of the through hole, it is difficult to properly close the space between the through hole and the insertion body. There is a risk that you will not be able to do so. Furthermore, when filling the space between the through hole and the insertion body with an irregularly shaped filler, it is necessary to work from both sides of the hollow wall in order to fill the space between the through hole and the insertion body on each wall. Yes, and work efficiency decreases.

Therefore, instead of the method of filling with amorphous filler, which has the various problems mentioned above, there is a method ( (hereinafter referred to as the "discharge filling method") has been proposed (for example, see Patent Document 3). By using a discharge filling method using a spray, a caulking gun, etc., it becomes easy to fill the partition penetrating portion, and work efficiency is improved.

Patent No. 6150933 Patent No. 6348320 Patent No. 6480775

When filling the compartment penetrating portion with a filler, the filler may not be properly filled unless the filler is filled after the filler receiver is installed in the compartment penetrating portion. Therefore, in order to hold the filler at a suitable location in the compartment penetration, filling work may be performed after installing a filler receiver for receiving the filler in the compartment penetration. In other words, in order to fill the partition penetrating portion with the filler, it is necessary to prepare both the filler and the filler receiver. However, the filler and the filler receiver are separate members, and if one is forgotten, the work will be delayed.

Therefore, the present invention aims to provide a section penetration treatment filling member, a section penetration treatment structure, and a method for constructing a section penetration treatment structure, in which the work of filling a section penetration part with a filler material is not delayed due to forgetting to arrange a member.

Refractory materials are thermally expandable members that expand when heated, or hydroxides such as aluminum hydroxide and magnesium hydroxide, carbonates such as calcium carbonate and magnesium carbonate, oxides such as magnesium oxide, phosphorus and phosphorus compounds, etc. A putty-like mixture that is a resin composition containing an inorganic material is preferred. As the insertion member 4, for example, a material equivalent to the above-mentioned thermally expandable material can be used as the filler. The thermally expandable member prevents the spread of fire by expanding in the event of a fire. The thermally expandable member as the insertion member 4 is formed from a thermally expandable resin composition. The thermally expandable resin composition contains a resin component and a thermally expandable material. Since the thermally expandable member is formed from a thermally expandable resin composition containing a resin component, the insertion member 4 can be easily bent and deformed, and as described above, a sheet or roll can be shaped into a sleeve. can do.
The noncombustible material for the insertion member 4 is defined by the Building Standards Act and the Building Standards Act Enforcement Order. Examples of the noncombustible material for the insertion member 4 include mortar, metal tubes such as steel sleeves, inorganic fibers, and molded bodies thereof.

As shown in FIG. 6, the insertion member 4 may have a circular shape, an elliptical shape, or a shape similar to these so that the outer peripheral surface can match the shape of the inner peripheral surface of the through holes 13A and 13B. By adapting the outer circumferential surface of the insertion member 4 to the shape of the inner circumferential surfaces of the through holes 13A and 13B, communication between the hollow portion 13 and the outside of the partition portion 11 can be prevented.

The construction method of the compartment penetration processing structure according to the second embodiment of the present invention includes a step of arranging the insertion member 4 in the compartment penetration part 15 before the step of arranging the filler receiver 3 in the compartment penetration part 15. It is preferable to further include. By including this step, the insertion member 4 that is passed from one through hole 13A to the other through hole 13B is provided in the partition penetrating portion 15, so that the hollow portion 13 and the outside of the partition portion 11 communicate with each other. can be prevented.

Further, by providing the insertion member 4 in the partition penetrating portion 15, it is possible to prevent the hollow portion 13 and the outside of the partition portion 11 from communicating with each other. Therefore, the compartment penetration treatment filling member 1 according to the third embodiment can form an appropriate fireproof structure in the compartment penetration portion 15 by performing construction on one side.

(Fourth embodiment)
The fourth embodiment differs from the first embodiment in that it further includes a covering function member 50, as shown in FIG. Hereinafter, the differences between the fourth embodiment and the first embodiment will be explained. Furthermore, in the following explanations of different embodiments, the same reference numerals are given to members having the same configuration.

The covering function member 50 is a member that further covers one of the through holes 13A of the partition penetrating portion 15 covered by the filling structure 5. The covering function member 50 is made of metal, resin material, rubber material, or the like. For example, as shown in FIG. 9, the covering function member 50 is divided into two parts, each consisting of a pair of divided pieces 50A and 50B, and the divided pieces 50A and 50B are butted against each other. The divided pieces 50A and 50B may be fixed to each other by, for example, providing a convex portion, a concave portion, etc. on each abutting surface, and fitting these portions together.
The covering function member 50 is cap-shaped and has a top surface 51 and a side surface 52 that stands up on the top surface 51. The inner diameter of the covering function member 50 (side surface 52) is larger than the diameter of the through hole 13A. Further, the top surface 51 is provided with a hole 51A through which the insertion body 21 is passed.
The hole 51A may be circular, but may have any other shape depending on the shape of the insertion body 21. The hole 51A may be smaller than the size of the insertion body 21. Moreover, a notch may be used instead of the hole 51A. Even if the size of the hole 51A is smaller than the insertion body 21, or even if a notch is provided in place of the hole 51A, if the covering function member 50 is made of rubber or resin material, the insertion body 21 will fit into the hole 51A. When inserted into the hole 51A (or the notch), the top surface 51 bends and the insertion body 21 can be inserted into the hole 51A (or the notch).

After the through-hole 13A is covered with the sheet-like cover material 3, the covering function member 50 is attached to the outer surface 11A of the partition portion 11, as shown in FIG. Here, the covering function member 50 is preferably divided into the two divided pieces 50A and 50B as described above, and the two pieces are butted against each other so as to sandwich the insertion body 21 from both sides and attached to the outer surface 11A.
Further, the covering function member 50 may be fixed to the outer surface 11A of the partition portion 11 by a known fixing means such as an adhesive, an adhesive, a screw, a tacker, etc., or the outer surface 11A may be provided with a concave portion, a convex portion, etc. The covering function member 50 may be fixed to the outer surface 11A by fitting or the like.

The covering function member 50 functions as a decorative material. The covering function member 50 is not limited to the function as a decorative material, and can provide various functions to the compartment penetration treatment structure. For example, the covering function member 50 may provide functions such as sound insulation, deodorization, and vibration damping to the compartment penetration processing structure 55. Note that the sound insulation performance and deodorization performance are functions that prevent sound leakage, odor leakage, etc. from one outer surface 11A (or 11B) side to the other outer surface 11B (or 11A). Moreover, the vibration damping performance is a function of preventing the insertion body 21 from vibrating.

The covering function member 50 exhibits certain sound insulation performance and deodorizing performance by covering the through hole 13A, and also exhibits a certain vibration damping performance by supporting the insertion body 21 by the inner peripheral surface of the hole 51A. However, the material of the covering function member 50 may be appropriately selected depending on the desired function. For example, when it is desired to provide a sound insulation function, the covering function member 50 is preferably formed of a sound insulation material such as a foam or a rubber material, and when it is desired to provide an odor prevention function, the covering function member 50 is formed of a resin material. It is recommended to add deodorants, deodorizers, etc. to the rubber material. Further, the covering function member 50 may be formed of a rubber material or the like when it is desired to provide a vibration damping function. Further, additional members may be attached to the inner surface (for example, the inner surface of the top surface 51) of the covering function member 50 depending on the function to be imparted, such as a sound insulating material, a deodorant, a deodorizer, etc. may be attached.

As described above, in this embodiment, by providing the covering function member 50 in the compartment penetration treatment structure, various functions can be provided to the compartment penetration portion 15 while forming an appropriate fire protection structure. Further, even when attaching the covering function member 50, an increase in the number of parts can be prevented, and all work can be done from one side of the partition portion 11 (outer surface 11A side), so work efficiency is improved.

Note that the covering function member is not limited to the above-described configuration. For example, as shown in FIG. 11, the covering function member 57 may be a single piece instead of being divided into two parts. The covering function member 57 is cap-shaped like the above-described covering function member 50, and has a top surface 58 and side surfaces 59, and a hole 58A is provided in the top surface 58. Further, the covering function member 57 has a slit 57A extending from the hole 58A toward the outer peripheral surface, and the slit 57A is formed across the top surface 58 and side surface 59. Since the covering function member 57 has the slit 57A, the insertion body 21 can be inserted into the hole 58A through the slit 57A even if it is not divided into two. Note that in the covering function member 57 as well, a cut may be provided in the top surface 58 instead of the hole 58A, similarly to the above-described covering function member 50.

Note that the covering function member is not limited to the above configuration, and may have any other configuration, for example, may be divided into three or more pieces. Further, for example, the covering function member was fixed to the partition part 11 (i.e., the outer surface 11A), but it does not need to be fixed to the partition part 11, and for example, it is fixed to either the sheet-like cover material or the insertion member. may be done. In this case, the covering function member may be fixed to either the sheet-like cover material or the insertion member from the outer periphery using a known fixing means such as an adhesive, a pressure-sensitive adhesive, a screw, a tacker, etc. It may be fixed by being
