Description

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

In order to facilitate drainage in apartment buildings, drainage pipes that penetrate the rooftop are installed to supply and exhaust air from the rooftop. In this case, since the rooftop slab is penetrated, the penetrating portion needs to be waterproofed. Regarding the construction method of this part, a waterproof joint is connected to a vertical pipe penetrating the rooftop slab, and a cover member, a control pipe member, and a ventilation fitting are connected to the waterproof joint. This ventilation fitting is called a vent cap, which is like a lid attached to the opening for intake and exhaust installed on the roof, and has a dome-shaped upper part to prevent rainwater from entering and insects from entering. It has a structure in which the air that rises upward from the vertical pipe is exhausted downward.

In this case, for example, the "rooftop ventilation device" disclosed in Japanese Patent Application Laid-Open No. 2006-124981 can be used. This "rooftop ventilation device" includes a pipe connecting member, a ventilation riser pipe having a hollow cylindrical shape and corresponding to the vertical pipe, and a riser pipe protection member.

However, when the riser pipe protection member is fixed, its lower end is located on the upper surface of the rooftop slab, and the weight of the riser pipe protection member and the external force acting on the weight of the riser pipe protection member are distributed and transmitted to the rooftop slab. is doing. Therefore, in order to support the weight of the riser pipe protection member by itself, it must be erected on the slab on the riser pipe protection room, and the height of the ventilation riser pipe and the riser pipe protection member The heights need to match. That is, the height of the ventilation riser pipe corresponding to the vertical pipe is limited by the riser pipe protection member.

On the other hand, for example, depending on the apartment house, the ceiling on the lower floor may be used as the balcony on the upper floor. In that case, the ventilation riser pipe and the riser pipe protection member may be arranged on the balcony of the upper floor in order to exhaust the air on the lower floor. In that case, since the height of the ventilation riser used for the "rooftop ventilation device" is limited to the height of the riser pipe protection member, the height of the ventilation riser is further increased to the upper side. The problem arises that it cannot be exhausted. That is, in order to prevent the odor of the riser pipe protection member, by arranging the ventilation fitting part above the balcony on the upper floor, the odor from the riser pipe protection member is discharged so as not to flow into the floor above it. There is a problem that the request to do is not satisfied.

The sheath tube 120 can be replaced, and the ventilation fitting portion 10 of the present embodiment can be attached to the sheath tube 120.

In this way, the ventilation fitting portion 10 of this embodiment can be attached to the sheath tube 120. Specifically, the sheath tube 120 is inserted into the vertical tube 110, and the sheath tube 120 is projected from the upper end of the vertical tube 110. The outside of the protruding sheath tube 120 is covered so that the inner cylinder portion 41 of the cover portion 40 in the ventilation fitting portion 10 of the present embodiment is in contact with the outside, and the bolt is provided to the fixing hole 41a through the stop hole 42a in the outer cylinder portion 42. Fix at 41b. In this way, the ventilation fitting portion 10 of this embodiment can be attached to the sheath tube 120. Further, 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. The second SUS band 26 made of stainless steel can be arranged so as to tighten the ends of the vertical pipe 110 and the waterproof layer 130. Further, 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 tighten the ends of the vertical pipe 110 and the sheath pipe 120.

The diameter difference between the sheath tube 120 and the inner cylinder portion 41 is preferably a diameter difference that causes resistance during fitting, and the diameter of the inner cylinder portion 41 is preferably larger than the diameter of the sheath tube 120. .. Further, the inner cylinder portion 41 has a fixing hole 41a, by screwing so as to enter the bolt 41b to the fixing hole 41a, the bolt 41b is in contact with the sheath pipe 120, further, the bolts 41b By pressing the sheath tube 120, the vertical tube 110 can be fixed to the inner cylinder portion 41.

In this way, since the sheath tube 120 can be inserted into the vertical tube 110 and the ventilation fitting portion 10 of the present embodiment can be attached to the sheath tube 120, the sheath tube 120 and the ventilation of the present embodiment attached to the sheath tube 120 can be attached. Only the metal fitting portion 10 can be replaced. Therefore, the construction period can be shortened, and the replacement cost can be further reduced because the replacement can be performed only by the plumbing contractor without the involvement of the building waterproofing contractor.

That is, since the ventilation fitting portion 10 of this embodiment can be attached to the sheath pipe 120, the sheath pipe 120 and the ventilation fitting portion 10 of the vertical pipe 110 covered with the waterproof layer 130 are maintained in that state. Can be updated. In this case, if the waterproof layer 130 is renewed, the building waterproofing company will do it, which may prolong the construction work and increase the renewal cost. Further, in many cases, the life of the ventilation fitting portion 10 is earlier than the deterioration of the waterproof layer 130. It can be carried out. Therefore, it is possible to carry out the renewal work in a relatively short period of time by reducing the cost of the renewal work and reducing the joint work between the building waterproofing company and the plumbing company.

The configuration of the ventilation fitting portion 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 will be omitted. Needless to say, the diameter of the inner cylinder portion 41 to which the sheath tube 120 is attached is appropriately changed so as to be fitted with the sheath tube 120. The vertical pipe 110 and the upper end of the sheath pipe 120 are made of another sealing material 170 to maintain watertightness and prevent rainwater from entering. Watertightness is enhanced by tightening the sealing material 170 with a second and second SUS band 25 made of stainless steel. 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, and similarly to the above, the ventilation fitting portion 10 of the present embodiment can be attached without depending on the length (height) of the vertical pipe 110, and thus depends on the height of the vertical pipe 110. The ventilation fitting portion 10 can be arranged regardless of its height.

The ventilation fitting portion 10 circulates the exhaust gas from the vertical pipe 110 through the sheath pipe 120, and circulates the exhaust gas through the cover portion 40 and the ceiling portion 50 in the ventilation fitting portion 10. That is, the exhaust gas passes through the inner cylinder portion 41 in the cover portion 40, and further descends so as to be folded back through the ceiling portion main body 51 in the ceiling portion 50, and the inner cylinder portion 41 in the cover portion 40 and the outer cylinder portion 42. It passes between, and is produced to the outside. The opposite is true when inhaling outside air. As described above, since the ventilation fitting portion 10 has the cover portion 40, even when a strong wind blows and a negative pressure is generated on the ventilation fitting portion 10, the negative pressure into the vertical pipe 110 is exerted. The effect of pressure can be mitigated. Further, as described above, it is possible to alleviate the influence of negative pressure on the so-called deodorant trap (not shown) connected to the vertical pipe 110.
