Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is directed to the discharge of moisture generated from within a concrete slab after waterproofing the surface of a concrete slab on the roof of a building, etc. The present invention relates to an exhaust device used for exhausting the inside of a drain pipe.

(Prior art) Conventionally, in any of the above cases, the exhaust system has an exhaust pipe that extends from an exhaust passage provided between a waterproof sheet and a concrete slab, or from a drainage pipe installed inside a building and extends through a concrete slab. The exhaust pipe is connected to an exhaust passage consisting of a penetrating exhaust branch pipe and is provided so as to protrude upward from the concrete slab surface, and in order to protect the outer peripheral surface of the exhaust pipe from rainwater, a waterproof sheath 1 is provided on the outer peripheral surface in a cylindrical shape. A metal wire is wound around the outer circumferential surface of the cylindrical waterproof sheet in a coil shape in order to cover the outer circumferential surface of the cylindrical waterproof sheet and to firmly and liquid-tightly fix the cylindrical waterproof sheet to the outer circumferential surface of the exhaust pipe. Currently, it is tightened and fixed.

Figure 5 shows an example of a conventional exhaust system, where A is a conical exhaust pipe, B is a cylindrical waterproof sheet applied to the outer circumferential surface of the exhaust pipe, and C is a metal made of coiled material applied to the outer circumferential surface of the exhaust pipe. wire, D is a waterproof sheet laminated construction layer applied to the upper surface of the concrete slab E on the roof of the building, F is an exhaust passage formed between the surface of the slab E and the insulating waterproof sheet d of the waterproof sheet construction layer;
G indicates a cylindrical space inside the exhaust pipe A that communicates with the exhaust passage F through a perforation H formed in the layered surface of the waterproof sheet.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional exhaust system, the cylindrical waterproof sheet that waterproofly covers the outer peripheral surface of the exhaust pipe is tightly wrapped around the outer peripheral surface with metal wire. Therefore, these coiled metal wires are always deeply wedged into the surface of the tarpaulin sheet, so over time, the portions of the tarpaulin sheet where the wires are wedged in become fatigued quickly and cracks tend to occur, making it difficult to use. Lifespan is relatively short. Moreover, the exhaust pipe is
If it is exposed to the outside air, receives direct sunlight, is exposed to rain water, or is hit by foreign matter or adheres to it, its deterioration is accelerated. This has disadvantages such as accelerated deterioration of wires and corrosion of the wires.

(Means for Solving the Problems) The present invention eliminates the above-mentioned conventional drawbacks, and provides strong and good tightening of the cylindrical waterproof sheet that waterproofly covers the outer peripheral surface of the exhaust pipe.
In addition, the present invention provides an exhaust system that can maintain a good tightening and waterproof state over a long period of time, and whose waterproof sheet can be easily replaced. An exhaust pipe is installed to communicate with the exhaust pipe, a waterproof sheet is wrapped around the outer peripheral surface of the exhaust pipe in a cylindrical shape, and a wide belt-like body is wrapped around the outer peripheral surface of the cylindrical waterproof sheet. The cylindrical waterproof sheet is fluid-tightly crimped and fixed to the circumferential surface of the exhaust pipe through the wide band-like body using a wide band.

Furthermore, the present invention provides an exhaust system that can protect the exhaust system from the adverse effects of the outside world and further guarantee its long-term use when using the exhaust system of the first invention. It has a structure in which the upper surface of the exhaust pipe and the outer peripheral surface of the cylindrical waterproof sheet are covered with a shade body, leaving an exhaust space.

(Example) Next, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an example of implementing the present invention, which is applied in waterproofing construction. That is, in the drawing, (1) shows a concrete slab on the roof of a building, and an insulating and waterproof construction layer (2) is applied to the upper surface of the concrete slab.

The waterproof construction layer (2) is completed by laminating and pasting C). Typical waterproof sheets include asphalt roof ink, rubber asphalt roof ink, and synthetic resin roof ink.

After carrying out such waterproofing construction, concrete slab (1
) rises due to solar heat, etc., and is exhausted as steam from the upper surface into the exhaust passageway (3), so during waterproofing construction, so that this humid air can be constantly exhausted to the outside, At a predetermined location on the surface of the waterproof construction layer (2), apply the waterproof construction layer (
A perforation (4) of a predetermined size is formed through the perforation (2), and an exhaust pipe (5) is provided on the upper surface of the perforation (4) so as to protrude upward in alignment with the perforation (4). ) exhaust passage (3
), thereby allowing the humid air in the exhaust passage (3) to be exhausted to the outside via the exhaust pipe (5).

The exhaust pipe (5) usually has a wide annular base plate (
5a), which are installed on the upper surface of the insulating waterproof sheet (2a) of the waterproof construction layer (2) around the outer periphery of the perforations (4), and are equally spaced on the circumference of the substrate (5a). The exhaust pipe (5) is fixed by screwing a fixing member such as a screw through the three screw holes (5b) into the hole of the concrete slab.

It is preferable that the exhaust pipe (5) has a cylindrical shape, and an exhaust hole (7> is provided at the center of the top surface of the exhaust pipe (5).

The exhaust pipe (5) together with the substrate (5a) and the hollow small cylindrical body (8) may be made of either synthetic resin or metal, but are most preferably made of stainless steel. be done. It is optimal that the cylindrical cap av is also made of stainless steel.

The cylindrical cap (+1) has an outer periphery of the small cylindrical body (8),
It is fixedly installed by welding or mechanically locking into irregularities.

In order to waterproof and protect the outer peripheral surface of the exhaust pipe (5), at least one layer of a cylindrical waterproof sheet (+21, usually two or more layers) is provided to surround and fix the outer peripheral surface of the exhaust pipe (!i). Conventionally, in order to liquid-tightly fix a cylindrical sheet to the outer circumferential surface of an exhaust pipe, a metal wire was wound around the metal wire in a coil shape and tightened, resulting in the above-mentioned inconvenience.

According to the present invention, the liquid-tight fixation is performed as follows. That is, it is wide, for example, approximately half the height of the exhaust pipe (5) or more, and preferably has a length that goes around the outer peripheral surface of the exhaust pipe (5) at least once. have Preferably, a strong strip of metal, preferably stainless steel, having lengths that overlap each other at each end thereof (
13 is wrapped around the outer peripheral surface of the exhaust pipe (5). Thus, the entire outer peripheral surface of the exhaust pipe (5) extends over about half of its height.
7 - Can be wrapped around a surface. In the illustrated example, the wide belt-shaped body is wrapped so as to surround and protect the exhaust pipe (5) from the upper half of its height, beyond the shoulder of the exhaust pipe (5), to almost the top surface of the exhaust pipe (5). A stainless steel band atb is applied to the outer circumferential surface of the ae, and predetermined locations of a large number of locking slots (14a) provided at the ends of the band a@ are selected and tightened with threaded protrusions on the circumferential surface. The tightening length is adjustable with the screw (14b), and this tightening force is transmitted to the wide side of the wide band 03, and the cylindrical waterproof sheet ab is tightened on the inside of the wide side of the band 03. The exhaust pipe (5) is strongly and widely crimped to the outer circumferential surface of the exhaust pipe (5) to ensure a strong liquid-tight fixation. Thus, as before, the metal wire
The above-mentioned disadvantages such as the method of pressing and tightening the cylindrical waterproof sheet in a coil shape on the outer peripheral surface of the cylindrical waterproof sheet are eliminated, and the cylindrical waterproof sheet a There is no deterioration and a liquid-tight waterproof coating is guaranteed over a long period of time.

The cylindrical waterproof sheet (121) consists of two layers, an inner layer and a surface layer, and its upper end extends to the upper shoulder surface of the exhaust pipe (5), and its extended end and upper shoulder surface Seal material A9 was applied between the two to further strengthen waterproofness.

The lower end of the lower layer sheet of the cylindrical waterproof sheet 0 is connected to its exhaust pipe (

) so that it can be attached to the surface.

The wide band-like body (131) has a large number of elongated holes (Ie, ae,
When drilling ..., rainwater on the upper surface of the shoulder of the exhaust pipe (5) will flow away through this, and rainwater will not accumulate on the upper surface of the exhaust pipe (5) inside the surrounding wall of the strip (13). I tried not to.

By providing the exhaust system of the present invention in this manner, the cylindrical waterproof sheet 0 on the outer peripheral surface of the exhaust pipe (5) can be maintained firmly and liquid-tight for a long period of time. The exhaust pipe (5) has an internal space (6) that communicates with the exhaust passage (3) through the perforation (4), so that moisture from the concrete slab (1) is not transferred to the exhaust passage (3). The humid air that enters the exhaust tube (5) is discharged to the outside through the exhaust hole (7) of the exhaust pipe (5), the valve (9), and the exhaust hole aO of the cylindrical cap CIt).

= 10 - On the other hand, rainwater and moisture in the outside air are prevented from entering into the exhaust pipe (5) by opening the valve (7), thus ensuring good exhaustion.

In the above embodiment, the cylindrical waterproof sheet (a) on the outer periphery of the exhaust pipe (5) has a wide band (13) on the outer periphery, which allows it to come into contact with the outside air or rainwater, and to attract debris such as scattered dust and sand. Although this prevents damage and deterioration to some extent, it is preferable to completely protect it from the outside world.A preferred embodiment of the invention that achieves this objective is shown in FIG. All the configurations of the present invention shown in FIG. +71 and is provided with a flute body ('Ie).The flute body ae is formed into a cap-shaped body of any shape, and the material thereof may be any material such as hard synthetic resin or metal. Stainless steel is most preferable. In the illustrated example, a dome-shaped stainless steel cap was used considering the aesthetic appearance. The depth of the dome-shaped cap ae is as follows:
It is preferable to cover the outer periphery of the exhaust pipe (5) as much as possible, leaving a small space from the upper surface of the waterproof construction layer (2) at the lower end of the exhaust pipe (5). Thus, due to the envelopment of the pipe body ae, the valved cap (1) on the top surface of the exhaust pipe (5) inside thereof is

The flute body (lf9) is fixedly attached, for example, as shown in the figure. That is, it is attached to the lower end of the surrounding surface of the wide band body (1, 1) at equal intervals on its circumference. The three mounting legs (1! It) are arranged at equal intervals on the circumference at the lower end of one of the caps a and the mounting legs a9 are arranged facing outward and downward. With the flute body (I8) mounted on the exhaust pipe (5) as described above, each of the mounting legs (

Preferably, a donut-shaped flat plate (■) is placed on the upper end of the wide strip (13) so that the hat (lF! Apply so that the inner circumferential surface of ae is in contact with it.

In such a case, depending on the thickness of the cylindrical waterproof sheet applied to the outer periphery of the exhaust pipe (5) or the number of laminated sheets, a wide band-like body (surrounding Even if the diameter of the exhaust pipe (5) changes, the flute body (1 & Zero space for exhaust is obtained.

When the above donut-shaped flat plate is interposed, by designing the inner diameter of the donut-shaped flat plate to be larger than the outer diameter of the fishing cap av, a small annular exhaust space (17a) is automatically created between them. can be formed.

The above exhaust device of the present invention can be used for exhausting moisture from the exhaust passage (3) between the concrete slab (1) and the waterproof construction layer (2) applied to the upper surface thereof, as described above.
For example, it can be applied to an exhaust pipe from a drain pipe as shown in the fourth figure.

That is, in Fig. 4, the exhaust passage (3) is a passage made of a lead pipe, stainless steel pipe, etc., which is vertically inserted through a sleeve in an air-liquid tight manner into a hole penetrating the concrete slab (1) on the roof of the building. Consists of trachea @. The ventilation pipe [phase] is, for example, a branch pipe that extends vertically upward from a drain pipe (not shown) installed in the building. Thus, the gas in the drain pipe is discharged to the outside of the rooftop through this ventilation pipe ω, but in this case, the ventilation pipe ω is extended or welded to the above-mentioned exhaust pipe (5). This exhaust pipe (5)
In this embodiment, an exhaust system with attached body according to the present invention having the same structure as the embodiment described above is provided. The configuration of its main parts is the same as that of the previous embodiment, so it will not be described in detail. Incidentally, in this case, the above-mentioned valve device is not necessary and is therefore omitted. Concrete slab (1)
A waterproof 7111 layer (2) is applied to the surface as necessary.

(Effects of the Invention) According to the present invention, a wide band is applied to the outer circumferential surface of the cylindrical waterproof sheet applied to the outer circumferential surface of the exhaust pipe, and the belt is tightened from the outer circumferential surface through the wide band. As a result, the cylindrical waterproof sheet is widely pressed against the circumferential surface of the exhaust pipe and is firmly fixed in a liquid-tight manner, unlike the conventional method.
Fatigue and damage to the cylindrical waterproof sheet caused by wrapping and tightening a metal wire into a coil can be eliminated, and a stable exhaust system can be provided over a long period of time. Furthermore, since the exhaust pipe of the present invention covers the upper surface and the outer circumferential surface of the exhaust pipe, leaving a space for exhaust air, the cylindrical waterproof sheet can be protected from the harmful effects of the outside world such as sunlight, wind and rain, and is stable. It has the effect of extending the service life.
