Description

Technical Field

[0001] The present invention relates to a wall penetration sleeve unit installed in a portion penetrating a partition wall such as building interior decoration.

Background Art

[0002] Conventionally, in the installation work of a plurality of pipes penetrating a partition wall, the positions of sleeves are determined for each individual pipe, and studs made of lightweight steel frames (hereinafter abbreviated as LGS) are built at predetermined intervals while avoiding these sleeves. After attaching a gypsum board as a wall material, a part of the gypsum board is cut to provide a wall penetration portion through which a plurality of pipes pass.

[0003] Also, in conventional pipe work using sleeves, there are various processes such as drilling holes for each individual sleeve in the board and pipe work after the gypsum board construction, which takes time and effort.

[0004] On the other hand, a wall penetration sleeve unit has been proposed to shorten the construction period and improve the efficiency and safety of work (Patent Document 1). This wall penetration sleeve unit has a structure in which a horizontally long lid body and a frame body surrounding the outer periphery of the lid body are integrated, and a plurality of sleeves are provided at a plurality of locations on the lid body. This wall penetration sleeve unit corresponds to a partition wall, but in order to ensure fire resistance performance, an additional operation of directly attaching rock wool or glass wool to the lid body to which a plurality of sleeves are attached is required.

[0005] On the other hand, a pipe sleeve unit has been proposed to simplify the installation work of pipes and ensure sound insulation performance (Patent Document 2). This pipe sleeve unit is entirely composed of a metal box body, and rock wool or glass wool can be filled in this box body in advance. The box body is fixedly held in a cutout space of a steel frame by a support member located at the upper part of the outer frame and a fixing member 32 located at the lower part.

Mode for Carrying Out the Invention

[0017] Hereinafter, the configuration of the wall penetration sleeve unit of the present invention and the attachment mode of the wall penetration sleeve unit to the partition wall will be described with reference to the accompanying drawings.

[0018] [Configuration of Wall Penetration Sleeve Unit] The configuration of the wall penetration sleeve unit of the present embodiment will be described with reference to FIGS. 1 and 2. FIGS. 1(a) to (d) show the front shape, rear shape, plan shape, and right side shape showing the schematic overall shape of the wall penetration sleeve unit 10. The wall penetration sleeve unit 10 includes, for example, as shown in FIGS. 1(a) and 2(a), (b), a sleeve unit main body 20 in which a flat panel 11 and a cover panel 12 are integrated, a first spacer 16 whose lower side can be in surface contact with the upper side of the flat panel 11 with a predetermined overlapping margin, and a second spacer 17 whose lower side can be in surface contact with the upper side of the cover panel 12 with a predetermined overlapping margin.

[0019] The flat panel 11 of this embodiment is a processed material manufactured by bending and drilling a hot-dip galvanized steel sheet with a thickness of 1.6 mm that meets specific fire protection equipment specifications. As shown in FIGS. 1(b) and 2(a), flanges 11a and 11b with a predetermined width are formed on the bottom side and both side edges. The width B (FIG. 1(a)) of the flanges 11a and 11b is set to be slightly larger than the thickness of the gypsum board 2 of the partition wall 1, which will be described later with reference to FIG. 3. When the gypsum board 2 is installed so that the periphery (lower side and both side edges) of the wall penetration sleeve unit 10 is surrounded, the end 2a of the gypsum board 2 abuts against the flanges 11a and 11b on the lower side and both side edges of the wall penetration sleeve unit 10, and the end 2a is not exposed. Thus, the partition wall 1 at the position where the wall penetration sleeve unit 10 is installed ensures specifications in accordance with the certification by the Minister of Land, Infrastructure, Transport and Tourism and the standard construction instruction manual of the adopted gypsum board manufacturer. As the flat panel 11, a hot-dip galvanized steel sheet with a thickness of 0.8 to 3.2 mm can be used according to the design specifications of specific fire protection equipment or fire protection equipment, etc. Although the rust prevention effect is reduced, a rust-proof painted steel sheet can also be used depending on the installation site.

[0020] The cover panel 12 of this embodiment is a member assembled into a box-shaped body from a lid panel 13 manufactured by bending a hot-dip galvanized steel sheet with a thickness of 0.5 mm that has been drilled, and a frame-shaped side panel 14 surrounding the four sides of the lid panel 13. By joining both members so that the open surface of the cover panel 12 is closed with the flat panel 11, a sleeve unit main body 20 having a rectangular parallelepiped internal space 21 is formed inside.

[0021] The width (thickness) of the side panel 14 is approximately equal to the wall thickness of the partition wall 1, as shown in FIG. 3, and is set so that the end 2a of the gypsum board 2B on the side other than the flat panel 11 side of the two gypsum boards 2A and 2B that form the wall surface of the partition wall 1 can abut against the side surface of the side panel 14. In this embodiment, for weight reduction of the cover panel 12, the plate thicknesses of the side panel 14 and the lid panel 13 are set to 0.5 mm.

[0022] The sleeve unit body 20 is formed with two cylindrical through holes 22 of different sizes. In this embodiment, the through holes 22 are formed by a cylindrical panel 18 (plate thickness 0.5 mm) attached so as to connect the inner edges of two circular holes of different sizes provided at corresponding positions of the flat panel 11 and the lid panel 13, and a part of the internal space 21 of the rectangular parallelepiped is partitioned.

[0023] In the internal space 21 of the sleeve unit body 20, except for the part where the cylindrical through hole 22 is formed, it is preferable to fill the internal space 21 with rock wool 15 or the like according to the fire resistance and sound insulation performance required for the partition wall 1. As the filling material, glass wool is suitable as a material to replace rock wool, similar to the case of the partition wall 1.

[0024] As shown in FIGS. 1(b), (d), 2(a), and 2(b), the first spacer 16 of this embodiment is a processed plate material with a width equal to the inner dimension between the flanges 11b on the side edges of the flat panel 11, and flanges 16 (16a, 16b) of a predetermined width are formed on the upper side and the side edges. When the wall-through sleeve unit 10 is incorporated into the partition wall 1, the first spacer 16 is attached so as to have a predetermined overlap with the upper side position of the flat panel 11. When the wall-through sleeve unit 10 is attached to the opening reinforcing material 7 (FIG. 3) using screws 19, the lower side portion is overlapped with the flat panel 11, and the upper surface of the upper flange 16a is brought into close contact with the lower surface 4a of the upper floor slab 4, so that it is positioned between the upper side of the flat panel 11 and the lower surface 4a of the upper floor slab 4, and a role is played to prevent a gap from occurring between the lower surface 4a of the upper floor slab 4 and the upper side of the flat panel 11 of the wall-through sleeve unit 10. Also, as shown in FIGS. 3 and 4(a), the small end 2a of the gypsum board 2A is attached to the side flange 16b so as to be in close contact.

[0025] The second spacer 17 of the present embodiment is also a processed plate material similar in shape to the first spacer 16, as shown in FIGS. 1(c), (d), 2(a), and 2(b), with a width equal to the lateral dimension of the cover panel 12 and flanges 17a and 17b of a predetermined width formed on the side edges and the upper side. When attaching the wall-through sleeve unit 10 to the opening position of the partition wall 1, the second spacer 17 is disposed near the upper side of the cover panel 12. When the wall-through sleeve unit 10 is screwed to the opening reinforcement 7 from the flat panel 11 side, the flange 17a on its upper side is brought into close contact with the lower surface 4a of the upper floor slab 4, and it is positioned between the upper side of the cover panel 12 and the lower surface 4a of the upper floor slab 4 and screwed to the opening reinforcement 7, thereby playing a role of preventing a gap from occurring between the lower surface 4a of the upper floor slab 4 and the upper surface of the cover panel 12 of the wall-through sleeve unit 10. Further, as shown in FIGS. 3 and 4(a), the edge 2a of the gypsum board 2B is attached to the flange 17b on the side edge so as to be in close contact therewith.

[0026] In the present embodiment, through holes 22 for passing two pipes of different sizes are formed in the sleeve unit main body 20. Needless to say, the dimensions of the through holes 22, the sleeve unit main body 20, the first spacer 16, and the second spacer 17 are appropriately set according to the number of pipes and the pipe diameter. In addition, by prefabricating various wall-through sleeve units 10 with different numbers of pipes and pipe diameters in a factory according to the piping plan and transporting them to the site, the efficiency of on-site work can be improved.

[0027] [Configuration of partition wall 1] Hereinafter, the schematic configuration of the partition wall 1 provided with the above-described wall-through sleeve unit 10 will be described with reference to FIG. 3, and further, the portion through which the piping of the partition wall 1 integrally provided with the wall-through sleeve unit 10 passes will be described with reference to FIGS. 3 to 5.

[0028] Figure 3 shows a state where a wall penetration sleeve unit 10 as an embodiment of the present invention is attached to a partition wall 1, together with the partition wall 1 and a part of the upper floor slab 4. The partition wall 1 partially shown in Figure 3 is a known partition wall 1 to which two gypsum boards 2 (2A, 2B) are attached and fixed so as to sandwich lightweight steel studs 6 made of light gauge steel (LGS) erected at predetermined intervals on a runner (not shown) laid on the floor surface along the installation position of the partition wall 1 as a wall base material from both side surfaces. In the present invention, channel steel (lipped channel steel) is used as the LGS studs 6, opening reinforcement members 7, etc. Between the two gypsum boards 2 (2A, 2B) attached so as to ensure a predetermined wall thickness while sandwiching the stud 6, rock wool 5 that functions as a heat-resistant material, heat-insulating material, and sound-insulating material conforming to the design specifications (fire resistance performance, sound insulation performance) as the partition wall 1 is filled. The wall plate material constituting the partition wall 1 is not limited to the above-described gypsum board, and various non-combustible boards having equivalent fire resistance performance can be used.

[0029] [Attachment of Wall Penetration Sleeve Unit 10 - Attachment of Gypsum Board 2] The wall penetration sleeve unit 10 is a member prefabricated at a factory in advance according to the piping plan, and is provided at a location penetrating the partition wall 1 prior to the attachment work of the gypsum board 2 and the like. Around the opening on the partition wall 1 side, an LGS opening reinforcement member 7 is installed in a frame shape corresponding to the position where the penetration sleeve unit is to be attached. As shown in Figure 3, the wall penetration sleeve unit 10 is screwed at several locations with screws 19 to the frame-shaped opening reinforcement member 7 near the lower side and side of the flat panel 11. Then, the gypsum board 2 cut and shaped into a predetermined shape in advance is brought to the site and screwed to the stud 6 so as to abut on each surface of the flanges 11a, 11b, 16b, 17b formed on the outer peripheral edges of the flat panel 11, the first spacer 16, and the second spacer 17 of the wall penetration sleeve unit 10 fixed and held by the opening reinforcement member 7, thereby attaching and fixing it, and the partition wall 1 equipped with the wall penetration sleeve unit 10 is completed.

[0030] Here, the pipe holding situation by the wall penetration sleeve unit 10 of the present invention attached to the partition wall 1 will be described. In FIG. 3, two pipes 30, 31 penetrating the opening of the wall penetration sleeve unit 10 are virtually drawn. In the through-hole 22 through which these pipes 30, 31 penetrate, the gap between the periphery of the pipes 30, 31 and the cylindrical panel 18 is covered with rock wool 15 or the like, or a penetration process of filling with putty or the like is performed in the same manner as the conventional construction method. The pipes 30, 31 passing through the wall penetration sleeve unit 10 are suspended from the lower surface 4a of the upper floor slab 4 by hanging pipe fittings (not shown) before and after the partition wall 1.

[0031] FIG. 4(a) shows the cross-sectional shape of the partition wall 1 at the upper surface position of the cover panel 12, and FIG. 4(b) shows the cross-sectional shape of the partition wall 1 at the axial center positions of the two pipes 30, 31 passing through the cover panel 12. FIG. 5(a) shows the cross-sectional shape of the partition wall 1 at the side surface position of the cover panel 12, and FIG. 5(b) shows the side cross-sectional shape of the partition wall 1 at the axial center position of the large-diameter pipe passing through the cover panel 12. As is clear from each figure, the small ends 2a of the two gypsum boards 2 (2A, 2B) of the partition wall 1 in contact with the wall penetration sleeve unit 10 are both held so as to be in firm surface contact with the wall penetration sleeve unit 10 attached so as to be within the wall thickness of the partition wall 1, and the upper end surface of the gypsum board 2 is held so as to be in firm surface contact with the lower surface 4a of the upper floor slab 4. Therefore, the partition wall 1 provided with the wall penetration sleeve unit 10 of the present invention can exhibit performance conforming to the specifications in accordance with the certification by the Minister of Land, Infrastructure, Transport and Tourism and the standard construction guidance of the adopted gypsum board manufacturer.

[0032] Also, as shown in FIGS. 4(b) and 5(b), the cover panel 12 of the wall penetration sleeve unit 10 is filled with rock wool 15 having specifications that satisfy the same fire resistance performance and sound insulation performance as the rock wool 5 filled between the two gypsum boards 2 of the partition wall 1. Therefore, the design specifications of the partition wall 1 can also be ensured in the part of the wall penetration sleeve unit 10.

[0033] Note that the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in each claim. That is, embodiments obtained by combining technical means appropriately modified within the scope shown in the claims are also included in the technical scope of the present invention.
