Description

Technical Field

[0001] The present invention relates to a ventilation pipe connection cover member that connects to a ventilation pipe connected to a T-shaped pipe, and a ventilation pipe connection cover having a plurality of such ventilation pipe connection cover members.

Background Art

[0002] In order to facilitate drainage in apartment houses, a ventilation pipe penetrating the rooftop is installed to supply and exhaust air from the rooftop. In this case, waterproofing treatment is required for the penetration part in order to penetrate the rooftop slab. Regarding the construction method of this part, it is necessary to cover the ventilation pipe penetrating the rooftop slab with a waterproof cover and cover the part where the waterproof cover and the ventilation pipe contact each other.

[0003] On the other hand, for example, in some apartment houses, the roof of the lower floor may be used as a balcony of the upper floor. In that case, in order to exhaust the air of the lower floor, the above-mentioned ventilation riser pipe and the above-mentioned riser pipe protection member may be arranged on the balcony of the upper floor. In that case, since the height of the ventilation riser pipe used for the "rooftop ventilation device" is limited by the height of the riser pipe protection member, there is a problem that the height of the ventilation riser pipe cannot be further increased to exhaust upward. That is, in order to prevent odors from the riser pipe protection member, there is a problem that the requirement to discharge the odors from the riser pipe protection member so as not to flow into the upper floor by arranging a ventilation fitting above the balcony of the upper floor cannot be satisfied.

[0004] According to Japanese Patent Application Laid-Open No. 2020-2737 invented by the inventor of the present application to solve such problems, "a cover part including a hollow sheath pipe inserted inside the ventilation pipe, a cylindrical inner cylinder part for connecting to the sheath pipe, and an outer cylinder part covering the inner cylinder part and having a cylindrical shape, and a ceiling part having a dome-shaped ceiling part main body that is connected to the cover part and exhausts the exhaust air flowing from the sheath pipe into the inner cylinder part through the ventilation pipe downward" is disclosed.

[0005] This invention has been well-received in the market because it provides a ventilation fitting that prevents odors from rising pipes from flowing into upper floors and does not impose any height restrictions on the ventilation pipes. However, it has been pointed out that because the odors escape from near the ceiling, which has a dome-shaped ceiling body, the odor can linger around the ventilation fitting when using the balcony on the upper floor where the ventilation pipes are located.

[0006] [Patent Document 1] Japanese Patent Publication No. 2020-2737 [Disclosure of the Invention] [Problems that the invention aims to solve]

[0007] The present invention has been made in view of the above-mentioned points, and its objective is to provide a ventilation pipe connection cover member that allows a ventilation pipe to be inserted through which a ventilation pipe is connected to a T-shaped pipe for discharging odors at a position away from the surrounding area in order to prevent odors from drifting around the ventilation pipe, and a ventilation pipe connection cover having a plurality of such ventilation pipe connection cover members. [Means for solving the problem]

[0008] The first aspect of the vent pipe connection cover member for inserting a vent pipe connected to a T-pipe, which solves the aforementioned problem, comprises a first cylindrical member that forms part of a cylindrical shape for inserting a vent pipe connected to a T-pipe, and a second cylindrical member that forms part of a cylindrical shape having a larger diameter than the first cylindrical member that forms part of a cylindrical shape, wherein the first cylindrical member has a first lower end positioned at its lower end, and the second cylindrical member has a second upper end positioned at its upper end, and comprises a ceiling portion that connects the first lower end and the second upper end, and comprises connecting portions that are positioned between the first cylindrical member and the ceiling portion and protrude outward from them.

[0009] Furthermore, the ventilation pipe connection cover member from the second perspective is such that, in the first perspective, the inner circumferential surface of the first cylindrical member has a groove-shaped portion for housing a buffer member that is in close contact with the ventilation pipe.

[0010] Furthermore, the ventilation pipe connection cover member in the third viewpoint is such that, in the first or second viewpoint, the first cylindrical member has a first upper end portion positioned at its upper end, and further has a first upper end connection portion positioned to protrude from the first upper end portion.

[0011] Furthermore, the ventilation pipe connection cover in the fourth perspective has multiple ventilation pipe connection cover members from the first perspective, with the connection parts connected to each other.

[0012] Furthermore, the ventilation pipe connection cover from the fifth perspective has a first cylindrical member that forms part of a cylindrical shape for inserting a ventilation pipe that connects to a T-pipe, and a second cylindrical member that forms part of a cylindrical shape having a larger diameter than the first cylindrical member that forms part of a cylindrical shape, the first cylindrical member has a first lower end located at its lower end, and the second cylindrical member has a second upper end located at its upper end, and has a ceiling portion that connects the first lower end and the second upper end, and has a plurality of ventilation pipe connection cover members for inserting a ventilation pipe that connects to a T-pipe having the first cylindrical member and the ceiling portion, and the ventilation pipe connection cover members are integrated. [Effects of the Invention]

[0013] As the present invention is configured and operates as described above, it is possible to provide a ventilation pipe connection cover having multiple ventilation pipe connection cover members, which allows a ventilation pipe to be inserted through a ventilation pipe connected to a T-shaped pipe for discharging odors at a position away from the surrounding area in order to prevent odors from drifting around the ventilation pipe.

[Figure 5] This is a rear view showing the internal configuration of the ventilation pipe connection cover member in this embodiment. [Figure 6] This is a view from arrow VI in Figure 5. [Figure 7] This is a plan view of the ventilation pipe connection cover member of this embodiment. [Figure 8] This is a diagram showing the usage state of the ventilation pipe connection cover in this embodiment. [Best Mode for Carrying Out the Invention]

[0015] This embodiment will now be described with reference to the illustrated embodiment. In Figure 8, a ventilation pipe 200 is positioned to penetrate the slab 100 on the roof of a multi-unit residential building, and the ventilation pipe connection cover 10 of this embodiment can be attached to this ventilation pipe 200. Here, the ventilation pipe 200 is connected to a drain riser (not shown) in the multi-unit residential building, and is installed to penetrate the roof to draw in air from the roof in order to facilitate drainage from the drain riser. This ventilation pipe 200 is covered by a waterproof layer 500, and a stainless steel band 600 can be used to fasten the ventilation pipe 200 and the waterproof layer 500 together. It is also preferable to attach seals to close their ends 501 to maintain watertightness and prevent rainwater from entering.

[0016] As described above, the ventilation pipe connection cover 10 in this embodiment allows the ventilation pipe 200, which is covered by the waterproof layer 500, to pass through it, and the ventilation pipe 200 is connected to the T-shaped pipe 300. The T-shaped pipe 300 is connected to the second ventilation pipe 400, and the ventilation fitting 600 is connected to the second ventilation pipe 400, and air is supplied and exhausted from the ventilation fitting 600.

[0017] The ventilation pipe connection cover 10 of this embodiment is composed of a plurality of combined ventilation pipe connection cover members 12. That is, when the ventilation pipe connection cover 10 is integrally formed, the synthetic resin ventilation pipe 200 and the synthetic resin T-shaped pipe 300 are connected by adhesion. However, when the ventilation pipe connection cover 10 or the buffer member 150 that adheres closely to the ventilation pipe 200 described later deteriorates and needs to be replaced, or when the waterproof work needs to be repaired, the adhesion between the synthetic resin ventilation pipe 200 and the synthetic resin T-shaped pipe 300 cannot be removed, and they cannot be replaced. However, the ventilation pipe connection cover 10 composed of a plurality of combined ventilation pipe connection cover members 12 can be easily replaced while the synthetic resin ventilation pipe 200 and the synthetic resin T-shaped pipe 300 remain adhered by disassembling each of the plurality of ventilation pipe connection cover members 12. Although the ventilation pipe connection cover members 12 of this embodiment can be combined in two, the ventilation pipe connection cover 10 of this embodiment can be composed by combining three or more members (not shown).

[0018] Although not shown, the ventilation pipe connection cover can also be formed by integrating two ventilation pipe connection cover members 12. In this case, the above-mentioned connection part 50 is not necessarily required. Therefore, the difference between this ventilation pipe connection cover not shown and the above-mentioned ventilation pipe connection cover 10 is that it does not have the connection part 50.

[0019] The ventilation pipe connection cover member 12 has a first cylindrical member 20 that constitutes a part of a cylindrical shape for inserting the ventilation pipe 200 connected to the T-shaped pipe 300, and a second cylindrical member 30 that also constitutes a part of the cylindrical shape and has a larger diameter than the first cylindrical member 20 that constitutes a part of the cylindrical shape.

[0020] In other words, in this embodiment, two ventilation pipe connection cover members 12 are combined to form a ventilation pipe connection cover 10. When the first cylindrical members 20 are combined, they form a cylindrical shape, so the first cylindrical member 20 alone constitutes a part of a cylindrical shape. The same applies to the second cylindrical member 30. In this embodiment, since two ventilation pipe connection cover members 12 are combined, the first cylindrical member 20 and the second cylindrical member 30 have a semi-cylindrical shape.

[0021] Furthermore, when the first cylindrical members 20 are combined to form a cylindrical shape, the second diameter K2, which is the diameter of the cylindrical shape formed when the second cylindrical members 30 are combined, is larger than the first diameter K1, which is the diameter of the cylindrical shape formed when the first cylindrical members 20 are combined.

[0022] The first cylindrical member 20 has a first upper end portion 22 positioned at its upper end, and a thin plate-shaped first upper end connecting portion 23 positioned to protrude upward from the first upper end portion 22. The first upper end connecting portion 23 has bolt holes 23a for connecting to the ventilation pipe 200 and the T-pipe 300, as will be described later.

[0023] Furthermore, the inner circumferential surface 25 of the first cylindrical member 20 has a groove-shaped groove portion 26 for housing a buffer member 150 that is in close contact with the ventilation pipe 200. The first upper end connection portion 23 is positioned along the first circular arc portion 28, which is an arc of the first cylindrical member 20, and is positioned to have a gap M from the inner circumferential surface 25 of the first cylindrical member 20. The T-shaped pipe 300 can be placed in this gap M. That is, the ventilation pipe 200 is inserted through the inner circumferential surface 25, the T-shaped pipe 300 is placed in this gap M, and the ventilation pipe 200 and the T-shaped pipe 300 can be connected as described later by fixing them with bolts in the bolt holes 23a. The buffer member 150 can be, for example, an annular rubber one, and is intended to be in close contact with the ventilation pipe 200.

[0024] Furthermore, the ventilation pipe connection cover 10 has a ceiling portion 40. The ceiling portion 40 connects the first cylindrical member 20 and the second cylindrical member 30, and is positioned to connect the first lower end portion 21 located at the lower end of the first cylindrical member 20 and the second upper end portion 32 located at the upper end of the second cylindrical member 30.

[0025] Furthermore, the ventilation pipe connection cover member 12 has outwardly protruding connection portions 50, 50 on the first cylindrical member 20 and the ceiling portion 40. In plan view, the ventilation pipe connection cover member 12 has a shape enclosed by an arc, and the connection portions 50, 50 are located at both ends 45, 45, which are positioned at the first arc portion 28, which is the arc of the first cylindrical member 20, and the second arc portion 38, which is the arc of the second cylindrical member 30, when the ventilation pipe connection cover member 12 is viewed from plan (see Figure 7). In addition, the connection portions 50, 50 are thin plate-like and have holes 51, 51 in their centers for inserting bolts.

[0026] The ventilation pipe connection cover member 12 has a rib 60 at its right end R, 12a, when viewed from the rear (see Figure 5). The rib 60 is positioned at the right end 12a on the inner circumferential surface 46 of the ceiling portion 40 and the inner circumferential surface 35 of the second cylindrical member 30, and protrudes towards the front in Figure 5. This rib 60 fits into the inner circumferential surface 46 of the ceiling portion 40 and the inner circumferential surface 35 of the second cylindrical member 30 at the left end L, 12b, of the other ventilation pipe connection cover member 12 to be combined with. Therefore, when two ventilation pipe connection cover members 12 are combined to form the ventilation pipe connection cover 10 of this embodiment, it is designed to prevent water from easily entering the interior (see Figure 3).

[0027] Furthermore, the ventilation pipe connection cover member 12 in the above configuration is preferably made of metal, and preferably of aluminum. It may also be made of steel, stainless steel, or synthetic resin such as ABS or polyvinyl chloride.

[0028] The ventilation pipe connection cover 10 with the above configuration is attached to the ventilation pipe 200. First, the ventilation pipe 200 is covered with the waterproof layer 500, and the end 501 of the waterproof layer 500 is sealed. At this time, that part is secured with a stainless steel band 600.

[0029] The ventilation pipe connection cover 10 in this embodiment can be composed of two ventilation pipe connection cover members 12, but the two ventilation pipe connection cover members 12 are attached above the sealed end 501. At this time, a buffer member 150 that is in close contact with the ventilation pipe 200 is placed in the groove 26.

[0030] Next, two vent pipe connection cover members 12 are attached to the upper end portion 201 of the vent pipe 200 so that it protrudes upward. Specifically, bolts B are inserted through the holes 51, 51 in the connection portions 50, 50 and screwed in with nuts or wing nuts.

[0031] The T-shaped pipe 300 is attached to the upwardly protruding ventilation pipe 200 by covering it. A bolt is inserted through the bolt hole 23a of the second connecting portion 23 located at the first upper end 22 of the first cylindrical member 20, connecting the ventilation pipe 200 and the T-shaped pipe 300. The T-shaped pipe 300 is positioned so as to fit inside the second connecting portion 23, and the ventilation pipe 200 is positioned so as to fit inside the T-shaped pipe 300, and they are connected with the bolt.

[0032] An exhaust pipe 400 of sufficient length is connected to one end 301 of the T-shaped pipe 300, and a ventilation fitting 600 is connected to the tip of the exhaust pipe 400.

[0033] In this embodiment, the ventilation pipe connection cover 10 is positioned so that the ventilation pipe 200 is inserted through it, and a T-shaped pipe 300 can be connected to it, allowing the odor to be discharged to a location away from the ventilation pipe 200. Therefore, it is possible to prevent the odor from lingering around the ventilation pipe 200, and thus the balcony on which the ventilation pipe 200 is located can be used.

[0034] Furthermore, by removing the cover 350 placed at the opening 302 of the T-pipe 300, cleaning the inside of the T-pipe 300 and the inside of the vent pipe 200 becomes easier.

[0035] Furthermore, since the ventilation pipe connection cover 10 of this embodiment can be installed regardless of the length (height) of the ventilation pipe 200, the ventilation pipe connection cover 10 can be positioned regardless of the height of the ventilation pipe 200.

[0036] Furthermore, since the ventilation pipe connection cover 10 is composed of multiple ventilation pipe connection cover members 12, the ventilation pipe connection cover 10 can be replaced without removing the ventilation pipe 200 and T-pipe 300 by disassembling it, thereby reducing the cost of replacement work. In particular, when the ventilation pipe 200 and T-pipe 300, which are made of synthetic resin, such as PVC pipes, are connected by bonding them with adhesive, the ventilation pipe connection cover 10 can be replaced without removing the adhesive, further reducing the cost of replacement work. In addition, the replacement of the buffer member 150 also becomes easier at that time. [Explanation of Symbols]
