[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-284414 Summary of the Invention [Problem to be solved by the invention]

[0004] When constructing a concrete pigeon coop as described in Patent Document 1 on a roof slab, many work processes are required, such as arranging rebar, setting formwork, pouring concrete, curing the concrete, and removing the formwork, so it takes time to complete the construction. Furthermore, work such as installing piping in the attic on the floor below cannot begin until construction of the pigeon coop is complete, which can result in a longer construction period for the building.

[0005] An object of the present invention is to provide a rooftop piping extraction structure that can shorten the construction period of a building. [Means for solving the problem]

[0006] The present invention provides a rooftop piping extraction structure for extracting piping installed to the outdoors through a through hole provided in a rooftop slab, and comprises a box body having a downward opening portion that opens at the bottom and a side opening portion that opens at the side, which is installed on the rooftop slab to cover the through hole, and a panel material that is detachably attached to the side opening portion and has an insertion hole through which the piping is inserted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a rooftop pipe extraction structure according to an embodiment of the present invention will be described with reference to the drawings.

[0010] As shown in FIG. 1, a rooftop piping extraction structure 100 according to an embodiment of the present invention is a structure for preventing rainwater from entering the building through a through hole 11 provided in a roof slab 10 to pass piping 1, such as an air conditioning piping or a water supply piping, to the roof side of a building, and is used in place of rainproof structures such as a reinforced concrete structure called a pigeon coop that has conventionally been formed on the roof slab 10.

[0011] Fig. 1 is a cross-sectional view of the rooftop piping extraction structure 100, showing a cross section along line AA in Fig. 2. Fig. 2 is a front view of the rooftop piping extraction structure 100, and Fig. 3 is a rear view of the rooftop piping extraction structure 100. Figs. 4, 5, 6, and 7 are enlarged views of the parts indicated by the arrows B, C, D, and E in Fig. 1, respectively.

[0012] The rooftop pipe extraction structure 100 comprises a box body 20 that is installed on the rooftop slab 10 so as to cover a through hole 11 provided in the rooftop slab 10, and a panel material 50 that is detachably attached to the box body 20 and has an insertion hole 54 through which the pipe 1 is inserted. Note that the pipe 1 that is extracted to the outdoors through the panel material 50 is not limited to a fluid pipe such as an air conditioning pipe or a water supply pipe, but may be any pipe that is tubular and can be routed from indoors to the rooftop, and may be, for example, a cable such as a power supply line or a signal line.

[0013] The box 20 is a hollow structure formed into a substantially rectangular parallelepiped shape by aluminum or aluminum alloy plate materials, and each side and apex, which are joints of the plate materials, are welded to ensure airtightness. The material of the box 20 is not limited to aluminum or aluminum alloy, but from the viewpoint of ensuring airtightness, it is preferable to use a weldable metal, and particularly from the viewpoint of installation workability, it is preferable to use aluminum or aluminum alloy, which can reduce the weight of the box 20. Also, from the viewpoint of processability, it is preferable that the material of the box 20 is aluminum or aluminum alloy, which is relatively easy to process. If it is necessary to suppress deformation of the box 20, a galvanized steel plate or a stainless steel plate with high rigidity may be used.

[0014] The box body 20 has a side opening 21 that opens on one side and to which the panel material 50 is removably attached, and a lower opening 22 that opens on the bottom and has an opening area larger than that of the through hole 11, and the external size (three side dimensions) of the box body 20 is appropriately set taking into consideration the size of the side opening 21, i.e., the size of the outer diameter of the piping 1 held by the panel material 50 and the number of piping 1, and the size of the lower opening 22, i.e., the size of the through hole 11, etc.

[0015] As shown in Fig. 4, the box 20 is installed on the upper surface of the rising portion 12 of the roof slab 10, which rises around the through hole 11, via the lower edge portion 27 formed at the lower end. The opening surrounded by the lower edge portion 27 becomes the lower opening 22.

[0016] The lower edge 27 is formed by further bending the tip of the first bent portion 26 (bent portion) formed by bending the lower portion of the side surface 25 of the box body 20 inward around the entire circumference, so that the tip is downwardly approximately parallel to the side surface 25.

[0017] Meanwhile, one side of the angle iron 14 is fixed to the upper surface of the rising portion 12 via an anchor bolt (not shown) attached to the rising portion 12 along a fixing direction line F1. The box body 20 is attached to the upper surface of the rising portion 12 by fixing the lower end edge 27 to the other side of the angle iron 14 fixed to the rising portion 12 in this manner along a fixing direction line F2 with a fastening member such as a screw (not shown).

[0018] 2 to 4, a first gap G1 (gap) that can be filled with a sealant is formed around the entire periphery between the first folded portion 26 of the box body 20 fixed to the rising portion 12 in this manner and the upper surface of the rising portion 12. Note that in Figs. 2 and 3, the sealant is not shown in order to clearly show the gap to be filled with the sealant.

[0019] In the first gap G1 between the first bent portion 26 and the upper surface of the rising portion 12, the first back-up material 61a is first filled, and then the first seal material 62a is filled by caulking. Then, after the first seal material 62a has dried to a certain extent, the second back-up material 61b is filled, and then the second seal material 62b is filled by caulking.

[0020] In this way, by providing a double seal around the entire periphery between the box body 20 and the rising portion 12, it is possible to reliably prevent rainwater from entering through the gap between the box body 20 and the rising portion 12. In addition, because the box body 20 is installed on the upper surface of the rising portion 12, rainwater that has accumulated on the roof slab 10 is less likely to reach the gap between the box body 20 and the rising portion 12. The surface of the roof slab 10, including the rising portion 12, has been previously treated with a waterproofing coating or the like.

[0021] The panel material 50 is a member formed into a substantially flat plate shape from an aluminum or aluminum alloy plate material, and has a flat plate portion 51, a flange portion 53 formed on the outer edge of the flat plate portion 51, and an insertion hole 54 formed penetrating the flat plate portion 51. The panel material 50 is detachably attached to the box body 20 via the flange portion 53.

[0022] As shown in FIG. 5, the flange portion 53 is formed by further bending the tip of a bent portion 52, which is formed by bending the entire outer edge of the flat portion 51 toward the inside of the box body 20, so that the tip is approximately parallel to the flat portion 51 in a direction away from the insertion hole 54.

[0023] On the other hand, among the side surfaces 25 of the box body 20, a first side surface 25a on which the side surface opening 21 is provided has an annular mounting portion 29 to which a flange portion 53 of the panel material 50 is attached. As shown in Fig. 5, the mounting portion 29 is a portion formed by further bending a tip portion of a second bent portion 28 formed by bending the inner edge of the opening formed in the first side surface 25a all around toward the inside of the box body 20 toward the insertion hole 54 so as to be approximately parallel to the first side surface 25a. The opening surrounded by the mounting portion 29 becomes the above-mentioned side surface opening 21.

[0024] In this manner, the flange portion 53 is fixed to the mounting portion 29 formed on the first side surface 25a of the box body 20 along the fixing direction line F3 by a screw (not shown), so that the panel material 50 is attached to the box body 20.

[0025] Between the folded portion 52 of the panel material 50 fixed to the box body 20 in this manner and the second folded portion 28 provided on the first side surface 25a, a second annular gap G2 into which a sealing material can be filled is formed, as shown in Figures 2 and 5.

[0026] In the second gap G2, the first back-up material 63a is first filled, and then the first seal material 64a is filled by caulking. After the first seal material 64a has dried to a certain extent, the second back-up material 63b is filled, and then the second seal material 64b is filled by caulking.

[0027] In this way, by providing a double seal around the entire circumference between the first side 25a of the box body 20 and the panel material 50, it is possible to reliably prevent rainwater from entering through the gap between the box body 20 and the panel material 50.

[0028] 6, the panel material 50 has a tubular portion 55 formed in a cylindrical shape from the flat plate portion 51 toward the outside of the box body 20, and the inner peripheral surface of the tubular portion 55 forms the above-mentioned insertion hole 54. The tubular portion 55 may be fixed to the flat plate portion 51 by welding.

[0029] A third annular gap G3, which can be filled with sealing material, is formed between the outer peripheral surface of the piping 1 arranged in the insertion hole 54 in this manner and the inner peripheral surface of the cylindrical portion 55, as shown in Figures 2 and 6.

[0030] In the third gap G3, the first back-up material 65a is first filled, and then the first seal material 66a is filled by caulking. After the first seal material 66a has dried to a certain extent, the second back-up material 65b is filled, and then the second seal material 66b is filled by caulking.

[0031] In this way, by providing a double seal around the entire circumference between the panel material 50 and the piping 1, it is possible to reliably prevent rainwater from entering through the gap between the panel material 50 and the piping 1.

[0032] 1, the piping 1 taken out to the outdoors through the panel material 50 passes through a through hole 13a formed in a deck plate 13 constituting the roof slab 10 and a through hole 11 provided in the roof slab 10 to reach the inside of the box body 20, and is supported as necessary by a support bracket 17 attached to a sleeve material 16 provided in the through hole 11. Note that the support bracket 17 may be attached to the rising portion 12 via an anchor bolt (not shown) instead of the sleeve material 16.

[0033] In addition, the gap between the through hole 13a formed in the deck plate 13 and the piping 1 is sealed with a sealing material 18 such as aluminum tape, and insulation material 15 such as glass wool is laid between the through hole 11 provided in the roof slab 10 and the piping 1 until it reaches a predetermined thickness.

[0034] By providing the heat insulating material 15 and the sealing member 18 appropriately in this manner, the flow of heat and air between the space inside the box body 20 and the indoor space is blocked, which results in suppressing the occurrence of condensation inside the box body 20. The heat insulating material 15 also functions as a sound absorbing material that prevents the sound of rain caused by rain hitting the box body 20 from resonating indoors. Note that in order to further prevent the occurrence of condensation inside the box body 20 and the sound of rain from resonating indoors, a heat insulating material or a sound absorbing material may be provided so as to cover the outer surface of the box body 20.

[0035] Here, in the rooftop piping extraction structure 100 shown in Figure 2, two pipes 1 of approximately the same diameter are extracted to the rooftop, but if there is a change in the diameter or number of the pipes 1, the panel material 50 is replaced with one in which the position and size of the tubular portion 55 is changed to match the specifications of the changed pipes 1.

[0036] Specifically, for example, in the case of a modified example shown in Figure 8, if there is a change in the number and outer diameter of the pipes 1, in a conventional pigeon coop made of reinforced concrete or the like, it is practically difficult to change the diameter of the holes through which the pipes 1 pass or to increase the number of holes, whereas in the rooftop pipe extraction structure 100 of the above configuration, it is possible to easily accommodate this by attaching to the box body 20 a panel material 150 having insertion holes 154 formed therein corresponding to each pipe 1.

[0037] In addition, in the rooftop pipe extraction structure 100 configured as above, even when the cross-sectional shape of the pipe 1 is substantially rectangular as in the modified example shown in Fig. 9, it is possible to easily accommodate this by attaching to the box body 20 a panel material 250 having an insertion hole 254 formed therein corresponding to the cross-sectional shape of the pipe 1. Note that a plurality of pipes (not shown) may be arranged inside the pipe 1 having a substantially rectangular cross-sectional shape.

[0038] In addition to the side opening 21 and the lower opening 22, the box body 20 is provided with an upper opening 31 that opens at the top, a lid member 32 that can close the upper opening 31, an opposing opening 41 formed in the second side 25b (opposing side) that faces the first side 25a on which the side opening 21 is formed, and a closing panel material 42 that can close the opposing opening 41, and the lid member 32 and the closing panel material 42 are removably attached to the main body 23 of the box body 20.

[0039] As shown in Figures 1 and 7, the cover member 32 has a rectangular top plate portion 33, a side surface 34 extending downward from the top plate portion 33, a third folded portion 35 formed by folding the lower portion of the side surface 34 inwardly around the entire circumference, and a lower edge portion 36 formed by further folding the tip portion of the third folded portion 35 downward so that it is approximately parallel to the side surface 34.

[0040] The lid member 32 thus formed is attached to the upper edge 38 of the side surface 25 of the main body 23 via the lower edge 36. In order to prevent rainwater from accumulating on the upper surface of the lid member 32, it is preferable that the top plate portion 33 has a gentle slope with respect to the horizontal plane.

[0041] 7, upper edge 38 of side surface 25 is formed by further bending a tip of fourth folded portion 37, which is formed by folding the entire upper portion of side surface 25 of box body 20 inward, upward so as to be approximately parallel to side surface 25. The opening surrounded by upper edge 38 becomes upper opening 31.

[0042] The lower edge 36 of the cover member 32 is fixed to the upper edge 38 formed on the side surface 25 along the fixing direction line F4 by a screw (not shown), so that the cover member 32 closes the upper opening 31.

[0043] As shown in Figures 2, 3 and 7, a fourth annular gap G4 that can be filled with a sealing material is formed between the third bent portion 35 of the cover member 32 and the fourth bent portion 37 provided on the side surface 25.

[0044] In the fourth gap G4, backup materials 67a, 67b and sealing materials 68a, 68b are provided in a double layer, similar to the above-mentioned gaps G1, G2, and G3, respectively, so that it is possible to reliably prevent rainwater from entering through the portion where the cover member 32 is attached.

[0045] The closure panel material 42 has the same shape as the panel material 50 that does not have the insertion holes 54, and is attached to the side surface 25 of the main body portion 23 in the same manner as the panel material 50. Therefore, a detailed description thereof will be omitted.

[0046] In addition, in the fifth gap G5 (see FIG. 3) formed at the location where the blocking panel material 42 is attached, backup materials and sealing materials are provided in duplicate, similar to the above-mentioned gaps G1, G2, G3, and G4. This makes it possible to reliably prevent rainwater from entering through the location where the blocking panel material 42 is attached.

[0047] By providing the upper opening 31 and the opposing opening 41 in this manner in the box body 20, it is possible to improve the workability of work performed within the box body 20, such as the work of taking out multiple pipes 1 from indoors through the through hole 11 and the lower opening 22 and sending them to the side opening 21 of the box body 20, the work of sending multiple pipes 1 from outdoors to indoors through the side opening 21, the lower opening 22 and the through hole 11, the work of connecting the pipes 1 to each other within the box body 20, and the work of fixing the pipes 1 to the sleeve material 16 provided in the through hole 11 via a support bracket 17.

[0048] In particular, by providing an opposing opening 41 on the second side 25b (opposing side) opposite the first side 25a to which the panel material 50 is attached, the condition of the multiple pipes 1 extending from the through hole 11 toward the panel material 50 can be easily visually confirmed through the opposing opening 41.

[0049] In this way, the upper opening 31 and the opposing opening 41 function as openings for work and also as openings for inspection. Note that if work or inspection can be performed sufficiently through either the upper opening 31 or the opposing opening 41, the other opening does not need to be provided.

[0050] According to the above embodiment, the following effects are achieved.

[0051] In the rooftop piping extraction structure 100 configured as described above, the box body 20 installed on the rooftop slab 10 so as to cover the through hole 11 has a downward opening 22 that opens at the bottom and a side opening 21 that opens at the side, and the panel material 50 that is removably attached to the side opening 21 is provided with an insertion hole 54 through which the piping 1 is inserted.

[0052] Therefore, simply by installing the box body 20 with the panel material 50 attached on the roof slab 10 so as to cover the through-hole 11, it becomes possible to take out the piping 1 to the roof through the through-hole 11 and to prevent rainwater from entering the building through the through-hole 11. This makes it unnecessary to construct a pigeon coop made of reinforced concrete or the like on the roof slab 10 in order to prevent rainwater from entering through the through-hole 11, and as a result, the construction period for the building can be shortened.

[0053] Specifically, for example, when constructing a pigeon coop made of reinforced concrete or the like on the roof slab 10, the pipes 1 cannot be raised from inside the building until the construction of the pigeon coop is completed, which may delay interior work on the floors below. However, with the rooftop pipe extraction structure 100 configured as described above, for example, a box body 20 can be installed on the roof slab 10 so as to cover the through hole 11, and the box body 20 can be covered with a waterproof sheet or the like to prevent rainwater from entering the building, making it possible to simultaneously carry out work such as waterproofing on the rooftop side and interior work on the indoor side.

[0054] In addition, since the piping 1 is taken out to the outdoors through a panel material 50 that can be attached and detached to the box body 20, even if there is a change in the number, diameter, or cross-sectional shape of the pipes 1, by preparing in advance the panel material 50 with insertion holes 54 formed therein that correspond to the changed pipes 1, the construction period for renovating the building can be shortened and the renovation costs can be reduced.

[0055] In addition, the following modified examples are also within the scope of the present invention, and it is possible to combine the configuration shown in the modified example with the configuration described in the above embodiment, or to combine the configurations described in the different modified examples below.

[0056] In the above embodiment, the box body 20 is installed on the upper surface of the rising portion 12 rising from the roof slab 10. Alternatively, the box body 20 may be installed directly on the roof slab 10. Note that, in order to make it difficult for rainwater that has accumulated on the roof slab 10 to infiltrate into the building through the through-hole 11, it is preferable to provide a rising portion 12 that rises around the through-hole 11 and install the box body 20 on top of it.

[0057] In the above embodiment, the gap formed between the panel material 50 and the first side surface 25a is sealed by the seal materials 64a and 64b. Alternatively, the gap formed between the panel material 350 and the first side surface 25a may be sealed by a gasket 365 sandwiched between the box body 20 and the panel material 350, as in the modified example shown in FIG. 10. In this case, the flat plate portion 351 of the panel material 350 is fixed to the first side surface 25a of the box body 20 via the gasket 365 by a fastening member such as a screw (not shown) along the fixing direction line F5, so that the panel material 350 is attached to the box body 20. Note that FIG. 10 shows a cross section corresponding to FIG. 5.

[0058] In order to improve the sealing performance, the tip of the bent portion 352 formed by bending the upper portion of the flat portion 351 of the panel material 350 in a direction away from the first side surface 25a may be further bent upward so as to be substantially parallel to the flat portion 351 to form a flange portion 353 that constitutes a sixth gap G6 between the first side surface 25a and the bent portion 352 and that can be filled with a sealing material. The sixth gap G6 thus formed is filled with a sealing material 364a by caulking, for example, from above. In order to reliably prevent the intrusion of rainwater, it is preferable to caulk a sealing material around the fastening members such as screws that fasten the panel material 350 and the box body 20.

[0059] In the above embodiment, the cylindrical portion 55, whose inner peripheral surface forms the insertion hole 54 of the panel material 50, protrudes from the flat plate portion 51 to an extent that a space is secured for filling the sealing materials 66a, 66b. Alternatively, the cylindrical portion 455, whose inner peripheral surface forms the insertion hole 454, may be formed to extend relatively long from the flat plate portion 451 toward the roof slab 10 so that the opening end 455a faces downward, as in the modified example shown in Fig. 11. Fig. 11 shows a cross section corresponding to Fig. 1.

[0060] In this way, when the open end 455a of the cylindrical portion 455 provided on the panel material 450 faces downward, rainwater is less likely to infiltrate through the cylindrical portion 455, so there is no need to fill a sealant between the pipe 1 and the cylindrical portion 455. The cross-sectional shape of the cylindrical portion 455 is not limited to a circle, and may be, for example, substantially rectangular. In this case, it is possible to easily take out a plurality of pipes 1 from indoors to outdoors through one cylindrical portion 455, i.e., one insertion hole 454, without interposing a sealant. The cylindrical portion 455 may be fixed to the flat portion 451 by welding, or may be fixed to the flat portion 451 by a fastening member such as a bolt (not shown).

[0061] Furthermore, in the above embodiment, it has been explained that the box body 20 and the panel materials 50, 150, 250, 350, 450 have portions that are formed by bending (e.g., the lower edge portion 27 and the flange portion 53, etc.), but these portions may be formed by any processing method as long as they have the shape shown in each figure, and for example, they may be formed by directly bending the members, they may be formed by drawing processing or the like, or they may be formed by welding the members together.

[0062] Although the embodiments of the present invention have been described above, the above-mentioned embodiments merely show some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above-mentioned embodiments.
