Description

  The present invention relates to a ventilation fitting used for a vertical pipe.

  For facilitating drainage in an apartment house, a drainage standpipe penetrating the rooftop is installed to supply and exhaust air from the rooftop. In this case, a waterproof treatment is required for the penetrating portion to penetrate the roof slab. Regarding the construction method of this part, a waterproof joint is connected to a vertical pipe penetrating the roof slab, and a cover member, an adjustment pipe member, and a ventilation fitting are connected to the waterproof joint. This ventilation fitting is called a vent cap, for example, a lid attached to an opening for air intake and exhaust installed on the rooftop.The upper part has a dome shape to prevent infiltration of rainwater and invasion of insects. It has a configuration in which ventilation rising upward from the vertical pipe is exhausted downward.

  In this case, for example, a “rooftop ventilation device” disclosed in JP-A-2006-124981 can be used. The “rooftop ventilation device” includes a pipe connecting member, a ventilation rising pipe having a hollow cylindrical shape and corresponding to the vertical pipe, and a rising pipe protection member.

  However, when the rising pipe protection member is fixed, the lower end thereof is located on the upper surface of the roof slab, and is arranged so that the own weight of the rising pipe protection member and the external force acting thereon are dispersed and transmitted to the roof slab. are doing. Therefore, in order to support the own weight of the riser protection member by itself, the riser protection member must be erected on the slab above the riser protection room. Height must be matched. That is, the height of the ventilation riser pipe corresponding to the vertical pipe is limited by the riser protection member.

  On the other hand, for example, in some apartment buildings, the ceiling on the lower floor may be used as a balcony on the upper floor. In such a case, the ventilating riser and the riser protection member may be arranged on a balcony of an upper floor to exhaust the lower floor. In this case, the height of the ventilation riser used for the “rooftop ventilation device” is limited by the height of the riser protection member. A problem arises in that exhaust cannot be performed. That is, in order to prevent the odor of the riser protection member, the ventilation fitting portion is disposed above the balcony on the upper floor, so that the odor from the riser protection member is prevented from flowing into the upper floor. There is a problem that the request to do so cannot be satisfied.

  Hereinafter, this example will be described with reference to the illustrated embodiment. In FIG. 1, a vertical pipe 110 as a ventilation pipe is disposed so as to penetrate a slab 100 on a rooftop of an apartment house which is a building. The vertical pipe 110 is installed so as to penetrate the rooftop to take in intake air from the rooftop for facilitating drainage in an apartment house. Further, the ventilation fitting part 10 of the present embodiment is arranged in the vertical pipe 110. The vertical tube 110 is covered with a waterproof layer 130, and the SUS band 20 is arranged so as to fasten the vertical tube 110 and the waterproof layer 130. In addition, a seal 150 is attached so as to close their ends to maintain watertightness, thereby preventing rainwater from entering.

  The ventilation fitting 10 of the present embodiment is connected to the vertical pipe 110 covered by the waterproof layer 130. As described above, the conventional rising pipe protection member needs to be matched with the height (length) of the vertical pipe 110, but the ventilation fitting 10 of this embodiment is limited to the height of the vertical pipe 110. It can be arranged without.

  The vertical pipe 110 is for supplying and exhausting air. The ventilation fitting section 10 that can be used as a ventilation fitting connected to the vertical pipe 110 has a cover section 40 and a ceiling section 50. The ventilation fitting 10 is provided to supply and exhaust air in the vertical pipe 110, and is further provided to prevent rainwater from entering. Further, the cover portion 40 is for preventing rainwater from entering a connection portion with the vertical pipe 110, and is for protecting this connection portion.

  The cover part 40 has an inner cylinder part 41, an outer cylinder part 42, and an upper end part 43 connecting them. The inner cylindrical portion 41 has a tubular shape, as the name suggests, and is for connecting to the above-described tubular vertical tube 110. In addition, since the inner tube portion 41 is arranged so as to be in contact with the outer peripheral portion of the vertical tube 110, the diameter difference between the vertical tube 110 and the inner tube portion 41 may be a diameter difference that causes resistance when fitted. Preferably, the diameter of the inner cylindrical portion 41 is larger than the diameter of the vertical pipe 110. Further, the inner cylindrical portion 41 has a fixing hole 41a, and by screwing the bolt 42 so as to enter the fixing hole 41a, the bolt 42 comes into contact with the vertical pipe 110, and furthermore, the bolt 42 By pressing the vertical tube 110, the vertical tube 110 can be fixed to the inner cylindrical portion 41.

  The outer cylinder part 42 has a cylindrical shape, as its name implies, and its diameter and length below it are set to be larger than those of the inner cylinder part 41 so as to cover the entire inner cylinder part 41. In a state in which it is connected to the vertical tube 110, it is configured to hang down so as to cover the connection part. In other words, it has a double structure in which the inner cylindrical portion 41 is arranged inside and the outer cylindrical portion 42 is arranged outside.

  The outer cylinder part 42 has a stop hole 42a. The stop hole 42a is preferably arranged at the same height as the fixing hole 41a in the inner cylindrical portion 41 in a side view, and is for screwing the fixing hole 41a to the fixing hole 41a through the stop hole 42a. The stopper hole 42a can be closed by a rubber cap 42b. This is to prevent rainwater from entering.

  The upper end portion 43 is provided with a plurality of elongated arc-shaped ventilation holes 43a so as to surround the inner cylindrical portion 41 in a bottom view. This is to prevent small birds such as sparrows from invading (see FIG. 2C).

  In addition, the upper end portion 43 has a fixed pedestal 44 and a slide pedestal 45 for slidably moving (see FIG. 5) so as to rotate with respect to the ceiling 50 in a plan view (see FIGS. 2 and 3). reference). In addition, the fixed pedestal 44 is disposed so as to protrude outside the outer cylindrical portion 42 having a circular shape in plan view, and the slide pedestal 45 is disposed so as to protrude outside the outer cylindrical portion 42. It is arranged at a position facing the fixed pedestal 44 therebetween. Further, the fixed base 44 has a fixed base hole 44a which is a hole. Further, the slide pedestal 45 has a slide pedestal hole 45a which is a hole. These will be described later. The fixed base 44 and the slide base 45 are flat and have a rectangular shape in plan view.

  The ceiling 50 has a ceiling main body 51 serving as a main body thereof, and the ceiling main body 51 has a dome-like shape similar to a so-called vent cap. The ceiling main body 51 has a circular shape in a plan view, and has a ceiling pedestal 52 for connection with the fixed pedestal 44 via screws 60. In addition, a ceiling slide base 53 is provided. The ceiling pedestal 52 and the ceiling slide pedestal 53 are flat and have a rectangular shape in plan view. The ceiling 50 has a knob 55. The knob 55 is provided along the shape of the hemispherical dome-shaped ceiling main body 51, and has a thin plate shape. By gripping the knob 55, a user (not shown) can easily slide and move the upper end 43 with respect to the ceiling 50 in a plan view.

  The ceiling pedestal 52 and the ceiling slide pedestal 53 are arranged at positions facing each other across the ceiling body 51, and the ceiling pedestal 52 has a ceiling pedestal hole 52a that is a hole. The ceiling slide base 53 has a notch 53a having a notch shape.

  The cover part 40 and the ceiling part 50 are overlapped, and the slide pedestal hole 45a of the slide pedestal 45 and the ceiling pedestal hole 52a of the ceiling pedestal 52 are overlapped so as to communicate with each other. The pedestal hole 45 a and the notch 53 a of the ceiling slide pedestal 53 are overlapped and stopped with the thumb screw 65. By removing the thumbscrew 65, the ceiling part 50 can be rotated about the screw 60 horizontally with respect to the cover part 40, so that the cover part 40 can be slid with respect to the ceiling part 50 (FIG. 5). Thus, by exposing the cover portion 40, it is possible to remove dust and the like clogged in the plurality of elongated arc-shaped ventilation holes 43a arranged at the upper end portion 43. Also, it can be used for high-pressure washing or inspection of the piping from the roof. In the case of sliding movement, since the knob 55 can be gripped, the cover 40 can easily slide on the ceiling 50.

  The ventilation metal part 10 of the present embodiment having the above configuration is preferably made of metal, and is preferably made of aluminum. Alternatively, stainless steel or a synthetic resin such as ABS or vinyl chloride may be used. The ventilation fitting 10 of this embodiment is attached to the vertical pipe 110. That is, by covering the outside of the vertical pipe 110 so that the inner cylindrical part 41 of the cover part 40 of the ventilation fitting part 10 is in contact with the vertical pipe 110, and fixing the bolt to the fixing hole 41 a through the stop hole 42 a of the outer cylindrical part 42. The ventilation fitting 10 of this embodiment can be attached to the vertical pipe 110. In addition, by arranging the insect repellent net 70 above the upper end portion 43, the invasion of insects can be further prevented (see FIGS. 1 and 5).

  The ventilation metal part 10 of the present embodiment circulates exhaust air from the vertical pipe 110 and circulates exhaust air through the cover part 40 and the ceiling part 50 of the ventilation metal part 10. That is, the exhaust gas passes through the inner cylindrical portion 41 of the cover portion 40, and further descends through the ceiling main body 51 of the ceiling portion 50 so as to be folded back. , Is produced outside through the space. The reverse is true when the outside air is taken in. As described above, since the ventilation metal part 10 has the cover part 40, even when a strong wind blows and a negative pressure is generated on the ventilation metal part 10, the airflow into the vertical pipe 110 is prevented. The effect of pressure can be reduced. Therefore, the influence of negative pressure on a so-called deodorant trap (not shown) connected to the vertical pipe 110 can be reduced.

  In addition, since the ventilation fitting portion 10 of the present embodiment can be attached without depending on the length (height) of the vertical tube 110, the height of the vertical fitting 110 does not depend on the height of the vertical tube 110. Irrespective of this, the ventilation fitting part 10 can be arranged.

Further, the ventilation fitting part 10 of the present embodiment can minimize the construction period and construction cost by using the vertical pipe 110 covered with the waterproof layer 130 as it is, and change the skeleton structure before and after construction. Not only that, but also the asset value of the house can be increased. In addition, the number of components can be reduced as compared with a conventional structure including a ventilation fitting, a vertical pipe, and a cover. In addition, the ventilation fitting portion 10 of the present embodiment can be repaired in a smaller space than a conventional “rising pipe protection member”.

  Further, in FIG. 6, a vertical pipe 110 is arranged so as to penetrate a slab 100 on the roof of an apartment house which is a building. The vertical pipe 110 is installed so as to penetrate the rooftop to take in intake air from the rooftop for facilitating drainage in an apartment house. Further, a sheath tube 120 can be arranged on the vertical tube 110.

The vertical pipe 110 is covered with a waterproof layer 130. In addition, a hollow sheath tube 120 having a tubular shape is arranged so as to be inserted into the vertical tube 110. The sheath tube 120 can be replaced, and the ventilation fitting part 10 of the present embodiment can be attached to the sheath tube 120.

  As described above, the ventilation fitting portion 10 of this embodiment can be attached to the sheath tube 120. Specifically, the sheath tube 120 is made to protrude from the upper end of the vertical tube 110 while inserting the sheath tube 120 into the inside of the vertical tube 110. The outer cylindrical portion 41 of the cover portion 40 of the ventilation fitting portion 10 of this embodiment is put on the outside of the protruded sheath tube 120 so as to be in contact therewith. Fix at 42. In this manner, the ventilation fitting portion 10 of the present embodiment can be attached to the sheath tube 120. In addition, a seal 160 is attached so as to close the ends of the vertical pipe 110 and the waterproof layer 130 to prevent rainwater from entering. In addition, the second SUS band 26 made of stainless steel can be arranged so as to fasten the ends of the vertical pipe 110 and the waterproof layer 130. In addition, a seal 170 is attached so as to close the ends of the vertical pipe 110 and the sheath pipe 120 to prevent rainwater from entering. The third SUS band 25 made of stainless steel can be arranged so as to fasten the ends of the vertical tube 110 and the sheath tube 120.

  Note that the diameter difference between the sheath tube 120 and the inner tube portion 41 is preferably a diameter difference that causes resistance during fitting, and the diameter of the inner tube portion 41 is preferably larger than the diameter of the sheath tube 120. . Further, the inner cylinder portion 41 has a fixing hole 41a, and the bolt 42 is screwed so as to enter the fixing hole 41a, so that the bolt 42 comes into contact with the sheath tube 120, and further, the bolt 42 By pressing the sheath tube 120, the vertical tube 110 can be fixed to the inner tube portion 41.

  As described above, the sheath tube 120 is inserted into the vertical tube 110, and the ventilation fitting portion 10 of the present embodiment can be attached to the sheath tube 120. Therefore, the sheath tube 120 and the ventilation tube of the present embodiment attached thereto are attached thereto. Only the metal part 10 can be replaced. Therefore, the construction period can be shortened, and the replacement can be performed only by the plumbing contractor without the involvement of the building waterproofing contractor, so that the replacement cost can be further reduced.

  That is, since the ventilation metal part 10 of the present embodiment can be attached to the sheath tube 120, the vertical tube 110 covered with the waterproof layer 130 is maintained in that state, and the sheath tube 120 and the ventilation metal part 10 Can be updated. In this case, when the waterproof layer 130 is renewed, the construction waterproofing company will perform the renewal, which may cause a concern that the construction may be prolonged and increase the renewal cost. Further, in many cases, the life of the ventilation metal part 10 is shorter than the deterioration of the waterproof layer 130, so that the ventilation metal part 10 can be replaced only by the plumbing contractor without replacing the waterproof layer 130. It can be carried out. Therefore, it is possible to perform the renewal work in a relatively short time by reducing the cost of the renewal work and reducing the joint work between the building waterproofing contractor and the plumbing contractor.

  The configuration of the ventilation fitting 10 used here is the same as that described above attached to the vertical pipe 110, and the same reference numerals are given and the description thereof is omitted. Needless to say, the diameter of the inner cylindrical portion 41 to which the sheath tube 120 is attached is appropriately changed so as to fit the sheath tube 120. The upper ends of the vertical pipe 110 and the sheath pipe 120 are kept watertight by another sealing material 170 to prevent rainwater from entering. Watertightness is enhanced by tightening the second second SUS band 25 made of stainless steel from above the sealing material 170. Further, the third SUS band 26 made of stainless steel is arranged so as to fasten the vertical pipe 110, the sheath pipe 120, and the waterproof layer 130. As described above, the ventilation fitting 10 of the present embodiment can be attached without depending on the length (height) of the vertical pipe 110 in the same manner as described above. Regardless of the height, the ventilation fitting portion 10 can be arranged without performing the operation.

  The ventilation metal part 10 circulates exhaust gas from the vertical pipe 110 through the sheath tube 120, and circulates exhaust gas through the cover part 40 and the ceiling part 50 of the ventilation metal part 10. That is, the exhaust gas passes through the inner cylindrical portion 41 of the cover portion 40, and further descends through the ceiling main body 51 of the ceiling portion 50 so as to be folded back. , Is produced outside through the space. The reverse is true when the outside air is taken in. As described above, since the ventilation metal part 10 has the cover part 40, even when a strong wind blows and a negative pressure is generated on the ventilation metal part 10, the airflow into the vertical pipe 110 is prevented. The effect of pressure can be reduced. As described above, the influence of negative pressure on a so-called deodorant trap (not shown) connected to the vertical pipe 110 can be reduced.
