Description

[Technical Field]

[0001] The present invention relates to a compartment penetration device that is attached to a compartment penetration section through which long objects such as electric wires and pipes pass for fire prevention purposes, and to a compartment penetration structure that is constructed for fire prevention purposes at a compartment penetration section. [Background technology]

[0002] A compartment penetration hole is provided in a compartment penetration part of a structure (such as a building) through which a long object such as an electric wire or a pipe passes. The compartment penetration part can be, for example, a ceiling, a wall, or a floor. Measures are taken to block the compartment penetration hole for purposes such as fire prevention between compartments. For example, there is a structure described in Patent Document 1. However, with this structure, after construction, the heat-expanding fire-resistant material becomes hidden by the sheet material, making it impossible to see the fire-resistant material that functions in the event of a fire, and therefore it was not possible to check whether the construction was correct after construction.

[0003] [Patent Document 1] Patent No. 6898190 Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, an object of the present invention is to provide a compartment penetration part measure and a compartment penetration structure that allow the installation status to be easily checked even after installation. [Means for solving the problem]

[0005] The present invention is a measure for a compartment penetration part, comprising: a pipe part that is arranged with its end protruding outside a compartment penetration hole of a compartment penetration part that a structure has, and has an internal space that penetrates the compartment penetration part; a fire-resistant part that is arranged with respect to the pipe part so that its end protrudes outside the compartment penetration part, and has a heat-expandable fire-resistant material; and a cover part that is arranged at the end of the pipe part, so that it intersects with the internal space in the penetration direction and so that the fire-resistant part is visible from the outside.

[0006] The present invention also provides a compartment penetration structure comprising: a compartment penetration hole in a compartment penetration part of a structure; an elongated body that penetrates the compartment penetration hole; a pipe part that is arranged so that its end protrudes outside the compartment penetration part and has an internal space that penetrates the compartment penetration part and in which the elongated body can be placed; a fire-resistant part that is arranged relative to the pipe part so that its end protrudes outside the compartment penetration part and has a heat-expandable fire-resistant material; and a cover part that is arranged at the end of the pipe part so that the internal space intersects with the penetration direction when the elongated body is penetrated and that covers the fire-resistant part so that it can be seen from the outside.

[0007] According to these configurations, the fire-resistant portion remains visible even when the pipe portion is covered with the cover portion, so that the presence of the fire-resistant portion can be visually confirmed after installation.

[0008] The cover portion can also be positioned so as to come into contact with the fire-resistant portion.

[0009] According to this configuration, the dimension of the compartment penetration portion projecting outward is reduced.

[0010] Furthermore, the cover portion can be positioned away from the fire-resistant portion.

[0011] According to this configuration, the pipe portion is exposed, so that the presence of the pipe portion can be confirmed.

[0012] The pipe portion may also be made of a combustible material.

[0013] According to this configuration, if the pipe section is burned down during a fire, the space where the pipe section was located is filled with the expanded fireproof material.

[0014] The fire-resistant portion includes the fire-resistant material and a sheet material that is not thermally expandable, The sheet material may be arranged to protrude outside the compartment penetration portion.

[0015] According to this configuration, the presence of the fire-resistant portion can be visually confirmed by checking the sheet material. [Effects of the Invention]

[0016] According to the present invention, the fireproof portion is visible even when the pipe portion is covered with the cover portion, so the presence of the fireproof portion can be visually confirmed after installation. Therefore, the installation status can be easily confirmed even after installation. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] Next, the present invention will be described by taking up an embodiment. In the drawings, reference numerals for a plurality of parts having the same shape are basically shown in only one representative location.

[0019] The compartment penetration hole H (an example of a cross-sectional shape is shown in FIG. 3 ), to which the compartment penetration device 1 according to this embodiment is attached, is provided as a compartment penetration C, for example, in a reinforced ceiling as defined in Article 112, Paragraph 1, Item 1 of the Enforcement Order of the Building Standards Act. The “reinforced ceiling” refers to a ceiling that can prevent the spread of fire, and is, for example, a ceiling made of two or more reinforced gypsum boards, as shown in FIG. 3 (Ministry of Land, Infrastructure, Transport and Tourism Public Notice No. 694 of 2016). In the following description, the compartment penetration device 1 is described as being attached to a ceiling (a reinforced ceiling is an example). Therefore, the positional relationship in the description is that of a ceiling installation. Furthermore, the compartment penetration device 1 is assumed to be positioned horizontally relative to the structure (such as a building). Furthermore, the “penetration direction” in the following description refers to the direction along the thickness of the member (such as gypsum board) in which the compartment penetration hole H is provided.

[0020] As shown in Figures 1 and 2, the measure tool 1 for a compartment penetration part of this embodiment has a support frame part 2, a filling part 3, a pipe part 4, a fire-resistant part 5, and a cover part 6 (see Figures 3 and 4). In this embodiment, one support frame part 2 has four pipe parts 4-4 arranged in a linear row.

[0021] The support frame 2 is a box-shaped body that is perforated from the top to the bottom and is formed by bending and welding a non-combustible material (metal material, etc.) such as a steel plate. The support frame 2 may also be formed from a fire-resistant resin (thermosetting resin, etc.). The support frame 2 integrally includes a plate portion 21 that is located below when attached to the compartment penetration portion C, and a tubular portion 22 that is located above.

[0022] In this embodiment, the plate portion 21 has a rectangular outer edge to cover the compartment through-hole H, which has a rectangular shape when viewed head-on. Through-holes 211-211 for screw fastening are formed at the four corners. The plate portion 21 is flat. A substantially rectangular through-hole 212 is formed in the center of the plate portion 21. A portion of the filling portion 3 is exposed through the through-hole 212. The tube portion 4 and the fire-resistant portion 5 protrude downward from the exposed filling portion 3. The length of the short side 2121 of the rectangular portion of the through-hole 212 is smaller than the outer diameter of the fire-resistant portion 5 provided on the outer periphery of the tube portion 4. As shown in FIG. 2 , a curved portion 2123 is formed on the straight portion 2122 of the long side to fit the outer shape of the fire-resistant portion 5, thereby expanding the through-hole 212 in the direction along the short side 2121. The entire long side may be the straight portion 2122 without forming the curved portion 2123. In this case, the length of the short side 2121 can be made approximately equal to, for example, the outer diameter of the fire-resistant section 5. A plurality of small holes 213-213 penetrate the periphery of the through hole 212 in the plate section 21. A pin or the like (not shown) is inserted into each small hole 213 to fix the filling section 3 to the plate section 21.

[0023] In this embodiment, the cylindrical portion 22 has a rectangular cross-sectional shape and is a square cylinder that is open at the top and bottom. The cross-sectional shape of the cylindrical portion 22 can be, for example, similar to the outer edge shape of the plate portion 21, but is not particularly limited thereto. The dimensions of each side of the cross-section of the cylindrical portion 22 are smaller than the outer edge dimensions of the plate portion 21 and larger than the dimensions of the through-hole 212 of the plate portion 21. As a result, the outer portion of the plate portion 21 protrudes beyond the cylindrical portion 22 and forms a flange-like shape that surrounds the cylindrical portion 22. This flange-shaped outer portion of the plate portion 21 closes the gap between the compartment through-hole H provided in the structure and the cylindrical portion 22. Note that a fire-resistant material or insulating material such as rock wool may be placed on the outside of the cylindrical portion 22 to fill the gap. This blocks heat that passes through the plate portion 21 and heads toward the gap.

[0024] In relation to filling the gap between the compartment penetration hole H and the cylindrical portion 22, in this embodiment, a support frame fireproof portion 23 is provided on the outer periphery of the cylindrical portion 22, as shown in FIG. 3 . The support frame fireproof portion 23 is made of a thermally expandable fireproof material. In this embodiment, the support frame fireproof portion 23 is strip-shaped and is provided so as to surround the entire circumference of the lower end of the cylindrical portion 22. By providing the support frame fireproof portion 23, in the event of a fire, the support frame fireproof portion 23 expands, thereby closing the gap between the cylindrical portion 22 and the compartment penetration portion C (ceiling). Note that, as in this embodiment, it is preferable to position the support frame fireproof portion 23 at the lower end of the cylindrical portion 22 so that the end face of the support frame fireproof portion 23 is aligned with the upper surface of the plate portion 21, as this makes it easier to maintain a consistent position during manufacturing. However, this is not limited thereto, and it is sufficient that the support frame fireproof portion 23 be positioned in the gap between the cylindrical portion 22 and the compartment penetration portion C (ceiling) when installed. Furthermore, since the plate portion 21 is present below the support frame fire-resistant portion 23, when the fire-resistant material of the support frame fire-resistant portion 23 expands, expansion below the plate portion 21 is restricted, and expansion above the plate portion 21 is possible, so that the space between the tube portion 22 and the compartment penetration portion C (ceiling) can be efficiently blocked in the event of a fire.

[0025] A plurality of protrusions 221-221 are provided so as to extend inward from the upper end of the tubular portion 22. Two protrusions 221 are provided at each long side of the tubular portion 22, and one is provided at each short side. The number is not particularly limited. Each protrusion 221 is initially shaped to extend in the extension direction of the tubular portion 22, and is bent inward after the filling portion 3 is placed inside the tubular portion 22. The plurality of protrusions 221-221 can prevent the filling portion 3, which is fitted into the tubular portion 22, from shifting upward of the tubular portion 22.

[0026] 3, the lower end of the tubular portion 22 is bent inward to form a bent portion 222. This bent portion 222 abuts against the upper surface of the plate portion 21. In this embodiment, as shown in FIG. 2, the through hole 212 (specifically, the curved portion 2123) is formed so as to follow the fire-resistant portion 5. However, by forming the bent portion 222 in the tubular portion 22, an overlapping region between the plate portion 21 and the tubular portion 22 can be secured in a portion other than the portion along the fire-resistant portion 5, and thus a space for welding the plate portion 21 and the tubular portion 22 can be secured.

[0027] In this embodiment, rock wool is used as the filling section 3. Rock wool is a material exemplified in the aforementioned Ministry of Land, Infrastructure, Transport and Tourism Notification No. 694. The filling section 3 is rectangular parallelepiped-shaped and has four through holes 31-31 arranged in a horizontal linear row. Each through hole 31 is formed by punching. The filling section 3 is disposed inside the support frame 2. In this embodiment, the upper surface of the rectangular parallelepiped filling section 3 is positioned approximately at the same position as the upper end of the tubular section 22, as shown in FIG. 1 . However, the upper surface of the filling section 3 may be positioned higher than the upper end of the tubular section 22. Similarly, the lower surface of the filling section 3 is positioned at the same position as the upper surface of the plate section 21 in this embodiment, but a portion of the filling section 3 may protrude downward from the through hole 212 of the plate section 21. The pipe section 4 and the refractory section 5 are fitted into each of the through holes 31. The upper ends of the pipe section 4 and the refractory section 5 are positioned at the same position (so-called "flush") as the upper end surface of the filling section 3. However, the positional relationship is not limited to this. The pipe section 4 and the fireproof section 5 are held in position in the up and down direction relative to each through-hole 31 by friction between the fireproof section 5 and each through-hole 31. Note that a member that actively holds the position, such as a pin, or a member that increases frictional force may be separately interposed between the pipe section 4 / fireproof section 5 and each through-hole 31.

[0028] The surface of the filling section 3 may be partially covered with a covering material such as nonwoven fabric, resin material, etc. Alternatively, tape or the like may be attached to at least a portion of the upper surface of the filling section 3, and the tube section 4 may be exposed by punching or cutting a hole in the tape or the like only at a portion corresponding to the tube section 4 to be used.

[0029] The pipe 4 is a portion that is disposed relative to the compartment penetration hole H of a structure (such as a building). As shown in FIG. 3 , the end of the pipe 4 (the lower end when installed on the ceiling) is disposed so as to protrude outward (downward) from the compartment penetration hole C. The pipe 4 has an internal space 4S that penetrates the compartment penetration hole C. Although a circular pipe is used as the pipe 4 in this embodiment, the cross-sectional shape is not limited to a circular shape. Furthermore, in this embodiment, a thermoplastic resin pipe that disappears or shrinks during a fire is used as the pipe 4. That is, the pipe 4 is formed from a flammable material. With this configuration, if the pipe 4 is burned during a fire, the space where the pipe 4 existed (including the internal space 4S) is filled with the fire-resistant material that expands radially inward. This prevents the compartments separated by the compartment penetration hole C from penetrating through the compartment penetration hole H during a fire, thereby preventing the spread of fire between the compartments. Furthermore, the pipe 4 is preferably flexible enough to be bent in the axial direction. In this case, when the elongated body L has a curved shape, particularly in the portion of the tube portion 4 exposed below the support frame portion 2, the tube portion 4 can be easily made to follow this curvature.

[0030] As shown in FIG. 3 , the fire-resistant portion 5 is disposed relative to the pipe portion 4 so that its end protrudes outward (downward) from the compartment penetration portion C. The fire-resistant portion 5 includes a thermally expandable fire-resistant material. In this embodiment, the fire-resistant portion 5 is sheet-shaped and wrapped around the outer circumferential surface of the pipe portion 4. When the fire-resistant material of the fire-resistant portion 5 is positioned so that it protrudes from the compartment penetration portion C, heat during a fire is transferred quickly to the fire-resistant material without being attenuated by the filling portion 3, which is advantageous in that expansion can begin more quickly. The fire-resistant portion 5 may be provided with a fire-resistant material over its entire area. Alternatively, the fire-resistant portion 5 may include a sheet-like portion that does not have a fire-resistant function (thermal expansion function). That is, the fire-resistant portion 5 may include a fire-resistant material and a non-thermally expandable sheet material. The sheet material may be, for example, a resin film. The fire-resistant material and the sheet material can be integrated by adhesive or the like. In this case, at least this sheet material is disposed so as to protrude outward from the compartment penetration portion C. With this configuration, even if the fire-resistant material portion of the fire-resistant portion 5 is hidden by the filling portion 3, the presence of the fire-resistant portion 5 can be visually confirmed by checking the sheet material exposed from the filling portion 3. This is an indirect confirmation of the fire-resistant material. The surface of the sheet material can also be provided with a marking such as a color, pattern, or symbol. By providing such a marking, visibility when visually confirming the presence of the fire-resistant portion 5 can be further improved.

[0031] The cover 6 is disposed at the end of the pipe 4 (the lower end when installed on a ceiling). The cover 6 covers the pipe 4 so as to intersect the internal space 4S of the pipe 4 in the penetration direction. When the long body L penetrates the internal space 4S of the pipe 4, the cover 6 covers the pipe 4 so that the long body L is exposed. The cover 6 covers the pipe 4 so that the fire-resistant part 5 is visible from the outside. For example, two types of cover 6 can be used: a penetration-type cover 6A (see FIG. 3) that covers the long body L (electric wire, communication line (optical fiber, etc.), piping, etc.) that penetrates the pipe 4, and a closed-type cover 6B (see FIG. 4) that completely covers the end of the pipe 4. Note that FIG. 3 shows multiple electric wires as the multiple long bodies L to L.

[0032] The penetration-type cover 6A is attached to the pipe 4 through which the elongated body L penetrates. In this case, the elongated body L can function to pass electricity or fluid. On the other hand, the closed-type cover 6B is attached to the pipe 4 when the elongated body L does not penetrate, and when the pipe 4 is in an unused, unused, or dormant state. The closed-type cover 6B is attached to the lower end of the pipe 4 during installation to prevent dust and other foreign matter from entering the internal space 4S of the pipe 4 during distribution and installation of the compartment penetration device 1. Incidentally, although not shown, filling the upper end of the pipe 4 with a filler such as rock wool can function not only as a dust barrier together with the closed-type cover 6B but also as an improved fire resistance if a fire-resistant filler is selected. Similar to the closed-type cover 6B, such a filler can be packed into the pipe 4 prior to distribution and installation of the compartment penetration device 1 (e.g., during manufacturing).

[0033] The through-type cover 6A is sheet-shaped, e.g., an aluminum glass cloth (ALGC) sheet. It may also be a sheet with adhesive on one side, like adhesive tape. The cover 6A is used by wrapping it around the pipe 4 and the elongated body L while deforming it, such as by squeezing it. This cover 6A mainly seals the space between the inner circumferential surface of the pipe 4 and the elongated body L. The closed-type cover 6B is made of, for example, a resin and formed into a cap shape. The inner circumferential surface of the cover 6B engages with the outer circumferential surface of the pipe 4 by pressure welding or screwing. This cover 6B has a cylindrical portion 61 (in this embodiment, a cylindrical portion) with one end closed by a plate-shaped closing surface 62. Plate-shaped rock wool may be disposed inside the closing surface 62 (not shown). When the closing surface 62 receives heat from the outside during a fire, the rock wool can block the heat from being transmitted to the pipe 4 located inside the closing surface 62 for a certain period of time. This plate-shaped rock wool may be used selectively with the above-mentioned filler (rock wool, etc.), or both may be used in combination.

[0034] By configuring the cover portion 6 as described above, the fire-resistant portion 5 remains visible even when the cover portion 6 covers the pipe portion 4. Therefore, the presence of the fire-resistant portion 5 can be visually confirmed after construction, making it clear at a glance that the fire-resistant portion 5, which contains fire-resistant material that functions in the event of a fire, has not been left installed. In addition, in this embodiment, the cover portion 6 is positioned below and spaced apart from the fire-resistant portion 5. In this positional relationship, the pipe portion 4 is exposed between the fire-resistant portion 5 and the cover portion 6, so the presence of the pipe portion 4 can be confirmed along with the fire-resistant portion 5. Furthermore, compared to conventional construction methods using putty, the cover portion 6 can be easily adapted to the shape of the long body L even when the long body L is bent.

[0035] Next, the compartment penetration structure will be described. This compartment penetration structure is a structure in which the above-mentioned compartment penetration portion measure tool 1 is combined with a compartment penetration hole H through which a long body L passes. That is, this compartment penetration structure includes: a compartment penetration hole H of a compartment penetration portion C of a structure; a long body L that passes through the compartment penetration hole H; a pipe portion 4 that is arranged so that its end protrudes outside the compartment penetration portion C and has an internal space 4S that penetrates the compartment penetration portion C and can accommodate the long body L; a fire-resistant portion 5 that is arranged relative to the pipe portion 4 so that its end protrudes outside the compartment penetration portion C and that comprises a heat-expandable fire-resistant material; and a cover portion 6 that is arranged at the end of the pipe portion 4 so that it intersects with the internal space 4S in the penetration direction when the long body L has passed through it and that covers the fire-resistant portion 5 so that it is visible from the outside.

[0036] The construction of a compartment penetration structure (in the case of installation in a ceiling) is performed, for example, in the following order. Here, the explanation will be given assuming installation for a plurality of elongated bodies L to L. First, the plurality of elongated bodies L to L already arranged around the compartment penetration part C are pulled out from the ceiling so as to pass through the compartment penetration hole H. Then, they are bundled together in units that can be passed through the pipe part 4. In this embodiment, the plurality of elongated bodies L to L are divided into four groups by being bundled together. Next, the cap-shaped closing-type cover parts 6B are removed from the pipe parts 4 to be used among the plurality of pipe parts 4. In this embodiment, all four pipe parts 4 to 4 are used, so all cover parts 6B are removed. Next, the assembly of the elongated bodies L of each group is passed through the internal space 4S of each pipe part 4, thereby passing the plurality of elongated bodies L to L through the measure tool for compartment penetration part 1.

[0037] Next, the tubular portion 22 of the support frame portion 2 is inserted into the compartment through-hole H, and the plate portion 21 of the support frame portion 2 is fixed by screwing it against the surrounding portion of the compartment through-hole H in the compartment through-hole C. Next, the sheet-like penetration-type cover portion 6A is wrapped around the pipe portion 4 and each group of the elongated body L. At this time, the cover portion 6A should not cover the fire-resistant portion 5. When wrapping, the lower end of the cover portion 6A is squeezed so that it fits along each group of the elongated body L. If necessary, a non-flammable cord such as wire or adhesive tape can be wrapped around the squeezed portion. This completes the installation.

[0038] Here, conventionally, the portion where the elongated body L passes through the compartment through-hole H in the ceiling has been blocked with putty. When using putty, vibrations and the like can cause the putty to shift relative to the compartment through-hole H or to fall out of the compartment through-hole H. In contrast, in this embodiment, the possibility of shifting or falling out can be made relatively lower compared to using putty, so a stable construction state can be maintained for a long period of time.

[0039] It should be noted that the through-type cover section 6A does not necessarily need to be assembled into a kit with the support frame section 2, filling section 3, pipe section 4, and fireproof section 5 when delivered to the construction site prior to construction; aluminum glass cloth sheets (or tape) procured separately at the construction site may be used instead. The same applies to the rock wool mentioned above; it may be procured separately at the construction site. On the other hand, it is preferable to have the closed-type cover section 6B assembled as a set from the perspective of "keeping out dust" until construction begins.

[0040] As explained so far, the compartment penetration part measure device 1 and compartment penetration structure of this embodiment allow the presence of the fire-resistant part 5 to be visually confirmed after construction, which has the advantageous effect of making it easy to check the construction status even after construction.

[0041] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist of the present invention.

[0042] For example, the measure device 1 for a compartment penetration part in the above embodiment has been described as being attached to a ceiling (reinforced ceiling, etc.), but it is not limited to this and can be attached to various objects that correspond to the compartment penetration part C, such as a ceiling or floor.

[0043] Furthermore, the support frame portion 2 and the filling portion 3 of this embodiment are not essential to the present invention, and one or both of them may be omitted. In this case, a separate member that engages with both the partition through-hole H and the pipe portion 4 may be disposed in the partition through-hole H.

[0044] Furthermore, the support frame portion 2 can be formed in various shapes to match the shape of the partition through-hole H.

[0045] In the above embodiment, four pipes 4 are arranged in a linear row in one support frame 2. However, the number and arrangement of the pipes 4 are not limited to this, and may be one to three, or five or more, and may be arranged in two or more rows or randomly.

[0046] Furthermore, in the above embodiment, when a plurality of pipe portions 4 are provided, each pipe portion 4 has the same shape. However, this is not limited to this, and the cross-sectional shape, cross-sectional dimensions (diameter, etc.), and length of each pipe portion 4 may be different. Furthermore, the pipe portion 4 may be a pipe with a smooth surface, or a pipe with an uneven surface such as a corrugated pipe.

[0047] In addition, in the above embodiment, the cover portion 6 is configured to be positioned away from the fire-resistant portion 5. However, it may be configured differently so that the cover portion 6 is positioned so as to be in contact with the fire-resistant portion 5. With this configuration, the distance between the fire-resistant portion 5 and the cover portion 6 can be set to zero, and therefore the outward protrusion dimension of the compartment penetration portion C for the combination of the fire-resistant portion 5 and the cover portion 6 is reduced by the distance.

[0048] In addition, the through-type cover portion 6A is in a sheet shape in the above embodiment, but is not limited to this, and may be a molded product of resin or the like having a predetermined shape capable of covering the pipe portion 4.

[0049] The cover 6 may also be made of a heat-expandable fire-resistant material. In this case, the cover 6 may be formed integrally with the fire-resistant part 5. [Explanation of symbols]
