Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to ventilation pipes for buildings, especially apartment buildings.

Traditionally, synthetic resin pipes or metal pipes have been used as ventilation pipes in buildings, but synthetic resin pipes have the drawback of emitting toxic gas that can lead to loss of life. 1
When the temperature exceeds 000"C, metal pipes penetrating the floor or walls can cause damage to the adjacent rooms above, below, or to the side of the fire room.
There was a defect in that the fire spread because heat was conducted to C1.

Since the fireproof tubular structure of the present invention uses hollow tubes made of non-metallic and inorganic materials, there is no room for fire.

℃, the heat conduction temperature through the floor or wall to the adjacent room does not reach the wood ignition point of 260℃, which is 120 to 13℃.
It stays at 1st place at 0℃. Therefore, the present invention aims at preventing the spread of fire and ensuring the security of human life.

For this purpose, the present invention covers the inner surface of a hollow tube made of a nonmetallic inorganic material with an impermeable membrane made of synthetic resin, etc., and provides partitions in the axial direction inside the tube, so that the tubes can be separated from each other independently by the partition plates. The present invention provides a fireproof tubular structure in which a plurality of partitioned passages are formed in the axial direction.
It also improves moisture resistance and workability.

Next, we will explain the unexploded 8A based on the drawing.

FIG. 1 shows the entire cross section of the refractory tubular structure of the present invention, and FIG. 2 shows a side view of the refractory tubular structure.

The 301st illustration is shown below.

In FIG. 1.2, 1 is a hollow tube made of a non-metallic inorganic material, such as glass fiber reinforced cement or asbestos cement.

Reference numeral 2 denotes a thin film of water-impermeable synthetic resin coated on the inner circumferential surface of a hollow tube made of a non-metallic inorganic material by spraying, brushing, etc. to a thickness of about a5 mA, for example.

The thickness of this thin film may be 0.2 to 0.3 mm, and can be adjusted as necessary.

Moreover, instead of coating, a thin film formed in advance can be applied.

3 is a metal partition plate, which is inserted in the axial direction inside a hollow tube made of non-metallic inorganic material with a water-impermeable membrane broken on the inner surface of the front ship, and fixed with adhesive etc. be.

In FIG. 1, the ridges are, for example, odor removal passages in the toilet, and the ridges are, for example, exhaust passages in the kitchen and bathroom.

In the present invention, the odor from the toilet and the exhaust air from the kitchen and bathroom are ventilated separately through the partition plate inside the fireproof tubular structure, so there is no problem of the two types of air mixing or flowing back.

Furthermore, since the fireproof tubular structure of the present invention is made of a non-metallic inorganic material, it can withstand fire, and even if the impermeable membrane were to catch fire, toxic gases would be discharged to the outside of the building through the fireproof tubular structure. It has the effect of completely guaranteeing the safety of entering the building from toxic gases.

Moreover, the fire does not spread through the pipe.

It is possible to easily cover the inner surface of the hollow tube with a water-impermeable membrane made of synthetic resin, etc., and to manufacture the fireproof tubular structure at low cost.

In addition, when pipes made of non-metallic inorganic materials are used as ventilation pipes for a long time, they absorb water vapor from the exhaust air in bathrooms and kitchens, and the meat J! v- There was a problem that the water permeated through the entire surface and water droplets fell off, but the present invention has the effect of preventing this.

It is economical as it can reduce the labor involved in construction.

Although the present invention has been described with respect to a ventilation pipe, it is of course applicable to drainage pipes for rainwater, gray water, sewage, etc.

Furthermore, although the present invention has been described for the case where there are two passages, the present invention can be similarly applied to a fireproof tubular structure having three or more passages.
