Description

A Pipe and A Pipe Connecter for Prevention of Noise

The present invention forms noise blocking and absorbing means and flameproofing means on the outer surface of pipes and pipe fittings used for transporting various fluids such as water and sewage, and improves noise and sound absorption and flameproofing. And pipe fittings.

In more detail, in the pipe joint pipe used to connect the pipes and pipes used to transfer various fluids to each other, the outer surface of the pipe and pipe joint pipe to block the noise generated from the fluid to be transported It is possible to reduce the noise by blocking and absorbing the noise generated when the fluid is transported by forming (equating) multiple means of sound absorbing means and sound absorbing means, so that the outer surface is turned off naturally without burning when the flame touches it. It is to provide a pipe and pipe joint pipe with improved noise and flame retardant function that can be strengthened to the topic by forming (equipped) a flame retardant means.

Generally, pipes are used to transport various fluids, such as water and sewage.

Pipes used to transfer fluids as described above are manufactured using hard PVC or metal materials, and in recent years, it is common to manufacture mainly using hard PVC.

1 shows a pipe 1 formed in a cylindrical shape having a predetermined thickness, that is, PVC pipe 5 using rigid PVC, and FIGS. 2A to 2E show the pipe 1 formed as described above to communicate with each other. It shows the pipe joint pipe (2) that is used when connecting, that is, the PVC pipe joint pipe (6).

The pipe fitting pipe 2 illustrated in Figs. 2A to 2E is a right angled pipe fitting pipe 2-1, a 45 degree bending pipe fitting pipe 2-2, and a 45 degree pipe fitting pipe as illustrated in Fig. 2A. (2-3), a right angled pipe joint pipe (2-4), a straight connection pipe joint pipe (2-5), and the like are formed (molded) in various shapes and shapes.

In the conventional pipe 1 or pipe joint pipe 2 as described above, noise is generated while the fluid being transported collides with the wall surfaces of the pipe 1 and the pipe joint pipe 2, and the noise generated as described above Due to the vibration (shock wave) caused by the collision, the amplitude of the noise increases due to the resonance phenomenon inside the pipe, and the noise generated due to the resonance (resonance sound) increases as a result, and also occurs largely. Due to the vibration generated, the pipe 1 or the pipe joint 2 is increased in fatigue, and the pipe 1 or the pipe joint 2 is destroyed (such as a crack).

Noise in the pipes through which fluid is conveyed is known to occur severely in the pipe 1 and the pipe joint pipe 2 connecting the pipe 1 with each other.

Particularly, among the various types of pipe joint pipes 2, a rectangular bent pipe joint pipe 2-2 for switching fluid flows than a straight pipe joint pipe 2-5 for connecting the pipe 1 in a straight line. ) 45 degree bend pipe joint pipe (2-2), 45 degree branch pipe joint pipe (2-3), right angle branch pipe joint pipe (2-4), noise is generated a great deal It is known to occur extremely at the bend site where drop impact occurs frequently.

The noise generated above causes various adverse effects such as listening disturbance, sleep disturbance, discomfort, stress induction, increased blood pressure, digestive dysfunction, and increased white blood cells in daily life, directly or indirectly to the human body (physical and mental). It is known to have an adverse effect.

Moreover, in recent years, as the industry develops, people are more concerned about noise due to the emotion of pursuing a comfortable life, which is causing the seriousness of the noise.

Due to the increasing interest and severity of noise as described above, in each construction industry for building (building) factories and multi-unit houses (apartments), studies are being actively conducted to reduce noise generated when transferring fluids.

In particular, in the case of various apartments such as apartments, officetels and villas, the noise between floors is increasing, and the noise generated between the floors causes mental and physical stress between each other and leads to legal disputes.

Efforts to resolve the dispute caused by noise by reducing the noise between floors and pipes in which fluids (water and wastewater) are transported in the case of apartments (apartments) and the pipe joint pipes are generated. .

For example, in order to reduce the noise generated in the drainage pipe, various sound insulation materials such as glass fibers and nonwoven fabrics are wrapped on the outer surface of the pipe to suppress the noise from leaking to the outside.

However, this method increases the construction cost due to the additional cost of using the sound insulation material, the sound insulation material not only takes up a lot of volume, but also takes a lot of construction time, significantly reducing workability.

Therefore, in order to solve the above problems and closing, I proposed 'Noise reduction drainage pipe' of Application No. 20-1999-27489, which is soft PVC or rubber inside the drainage pipe or pipe fitting pipe. It is formed by bonding.

However, in the case of the noise reduction pipe, which has been filed previously, the noise reduction and the construction can be easier than in the prior art, but since the noise reduction layer is formed only inside the product, the noise reduction ability is somewhat lowered, Condensation may occur on the outside of the pipe due to the difference in drainage and the outside temperature of the pipe, which reduces the durability of the building where the pipe is installed.

In order to solve the above problems, I proposed a 'pipe and pipe joint pipe with a special resin layer having a noise reduction function' of Patent Registration No. 10-481673.

This is because the outer surface of the pipe or pipe fitting is equipped with a special resin layer having a noise reduction function, while obtaining a noise effect, without reducing the drainage capacity, it is possible to vary the thickness of the special resin layer in proportion to the noise effect. .

However, since the special resin layer is formed on the outer surface of the pipe or pipe fitting as a single layer, the noise reduction function and the condensation prevention function are inferior, and the noise blocking effect (function) cannot be expected at all, and the flame retardant function is not particularly formed. Therefore, in case of fire, pipes or pipe fittings are easily incinerated and lose their function.

The present invention relates to a pipe used for transferring various fluids and a pipe joint pipe used to connect the pipes to each other, wherein the outer surface of the pipe and the pipe joint pipe blocks and noise blocking the noise generated from the fluid being transported. The purpose of the present invention is to provide a pipe and a pipe fitting pipe having improved sound absorption and flameproofing by forming (equating) a sound absorbing means for absorbing the sound absorbing means and forming a flameproofing means at the outermost surface.

Another object of the present invention is to block and absorb (absorb) the noise generated in the fluid conveyed by the blocking means and the sound absorbing means formed on the outer surface of the pipe and pipe fitting pipe to reduce the noise and vibration generated when the fluid is transferred (Blocking and sound-absorbing), it can block the vibration and noise transmitted from the outside, and by the flame-proof means formed on the outer surface so that it does not burn when the flame hits, so that it is naturally turned off to enhance the topic It is to provide a pipe and pipe fittings with improved flame resistance.

Another object of the present invention is to obtain a good noise effect while not reducing the drainage capacity to facilitate the drainage, the thickness can be freely changed in proportion to the noise reduction effect, and the noise and condensation can also be prevented It is to provide a pipe and pipe fittings with improved flame resistance.

Is a cross-sectional view of the noise and flame retardant pipe 100 with improved noise and flame retardant function according to the present invention, Figures 6a and 6b is a perspective view showing the noise and flame retardant pipe pipe with improved noise and flame retardant function according to the present invention and It is a cross section.

I recognized that noise from pipes and pipe joints is closely related to the thickness of these pipes and pipe joints, and that the thicker the thickness, the less noise can be reduced.

Therefore, in order to obtain a relationship (effect) in which the thickness of the pipe and pipe fitting pipe is inversely proportional to the magnitude of the noise as described above, the noise and flame retardant improvement pipe according to the present invention has improved noise and flame resistance and noise and flame resistance. The thickness of the sound-proof flame-proof pipe fittings 200 with improved function is thickened, but the sound-proof flame-proof pipes 100 with improved noise and flame-retardant function and the hard flame-proof pipes with improved noise and flame-retardant function 200 are molded. Instead of thickening only the thickness of PVC, other layers (sound insulation layer, sound absorbing layer, and flameproof layer) are laminated outside the rigid PVC to achieve the purpose of reducing noise.

Noise and flame retardant pipe 100 with improved noise and flame retardant function and noise and flame retardant pipe with improved noise and flame retardant function according to the present invention was formed as follows.

Noise and flame retardant pipe 100 with improved noise and flame retardant function according to the present invention and noise and flame retardant pipe with improved noise and flame retardant function 200, the outer surface or pipe PVC pipe of the pipe 11 is formed of hard PVC On the inner surface and the outer surface of the sound pipe 21, a mineral sound insulating layer 12: an internal mineral sound insulating layer 22-1 and an external mineral sound insulating layer 22-2 is formed as a sound insulating layer, and the mineral sound insulating layer 12: an inner surface The main feature is that a sound absorbing layer, a sound insulating layer, and a flameproof layer are formed on the outer side of the mineral sound insulating layer 22-1 and the outer surface sound insulating layer 22-2.

Sound insulation is the blocking of sound waves propagating in the air with walls and the like so that sound energy cannot be transmitted to the other side. Sound absorption is the reduction of the reflection of sound energy from the surface of the room. It is to execute repeatedly to determine Acoustic quality.

The present invention, noise and flame retardant improvement pipe 100 and noise and flame retardant function improved noise and flame retardant function that can simultaneously perform the two properties such as sound insulation (sound insulation) and sound absorption (sound absorption) It is to provide a pipe joint pipe (200).

A mineral sound insulating layer 12 (22: an inner surface mineral sound insulating layer 22-1) formed as a sound insulating layer on the inner surface and the outer surface of the pipe 11 or the pipe PVC pipe fitting 21 formed of hard PVC; The outer surface sound insulation layer 22-2) also performs a function of absorbing / dispersing noise and impact and a soundproofing function of preventing the internal noise from leaking to the outside.

Examples of the minerals including porous minerals added to the mineral sound insulating layer 12 (22: the inner surface sound insulation layer 22-1 and the outer surface sound insulation layer 22-2) include zeolite, pearlite, ocher, tuff, Volcanic rock, pumice, pumice, and the like, and any one of these minerals may be selected, or a mixture of two or more of them (group).

In addition to the above minerals can be used in place of other known or newly developed minerals (including porous minerals), and therefore, of course, does not mean that the present invention is not limited to the minerals (including porous minerals) described above Will be.

The sound insulation layer 12 (22: internal mineral sound insulation layer 22-) in the noise flame retardant pipe 100 with improved noise and flame retardant function or the noise flame retardant pipe with improved noise and flame retardant function (22). The following are mentioned as a sound absorption layer, a sound insulation layer, and a flameproof layer laminated | stacked on the outer side of 1) and the outer surface acoustic sound insulation layer 22-2).

The ultra-microfiber sound-absorbing layer 24 may be mentioned as the sound absorbing layer.

The ultrafine sound-absorbing layer 24 may be formed of a resin foam pad (sheet) as a sound absorption (and sound insulation / buffer) material having a three-dimensional network structure formed by ultrafine fibers having a thickness of 0.1 μm to 20 μm.

It is preferable that the thickness of the ultra-microfiber is 0.1 μm to 20 μm, but when the thickness of the ultra microfiber is less than 0.1 μm (too thin), the mechanical properties are inferior and the restoring elasticity is weak, which is not preferable in terms of buffering ability, and exceeds 20 μm ( Too thick), the specific volume becomes small so that it does not have good sound absorption, and it is desirable that the thickness of the ultra-fine yarn is about 1/100 of the thickness of the human hair.

The microfiber resin foam pad (sheet) may be formed in a multi-layered structure in which separate functional members are bonded to one or both surfaces of the substrate, and the other functional member may be a waterproof sheet.

The resin foam pad (sheet) having a three-dimensional network structure formed by the ultra-fine yarn is preferably a large specific volume (m 3 / kg), and is formed in this manner so that the noise transmission path is long, thereby having excellent sound absorption. At the same time, the thermal insulation and buffering properties can be improved.

Specifically, the noise transmitted to the resin foam pad (sheet) having a three-dimensional network structure is plasticized in a long path along the microfiber and absorbed and dispersed (exhausted) in a large space, and is destroyed. It is possible to effectively eliminate the noise caused by the air, and also sufficient air is collected in a large space to obtain the effect of improving the thermal insulation and the like.

As the sound insulation layer formed (stacked) on the outer side of the ultrafine sound-absorbing layer 24, a special asphalt sound insulation layer 25 having improved ordinary asphalt having a low vibration damping ability may be mentioned.

The special asphalt sound insulation layer 25 is for maximizing sound insulation performance and at the same time maximizing sound absorption and cushioning performance. The vibration damping sheet is formed of a sheet of straight asphalt or blunt asphalt as a pad (pad). (Pad), weight-weighted asphalt which made the asphalt lightweight, foamed asphalt, etc. are mentioned.

The straight asphalt has a high elongation and excellent adhesion and waterproofness.

In addition, the blown asphalt has high durability, heat resistance, elasticity, impact resistance, water resistance, and electrical insulation, but its stretchability, water resistance, and adhesiveness are slightly weaker than those of straight asphalt, and it is a raw material of asphalt waterproof paper. It is used as a moisture proof material, electric insulation material, antirust paint, pipe coating material, roofing adhesive, etc.

The special asphalt sound insulation layer 25 may be molded (formed) by adding a conventional plasticizer to asphalt (asphalt), and the special asphalt sound insulation layer 25 configured as described above has a soft property having some elasticity. In addition, the soft softness can effectively block the noise.

The content of the plasticizer is preferably 50% to 200% by weight when the asphalt (asphalt) is 100, but if the content of the plasticizer is too (less), the effect of reducing noise decreases sufficiently to satisfy the desired purpose. It becomes difficult to achieve, and when the content of the plasticizer is too large (above the upper limit), the time required for the molding of the product is long, and the productivity decreases.

In addition, the special asphalt sound insulation layer 25 can be added to the addition of calcium carbonate, by adding the calcium carbonate in this way to facilitate the flow when forming the product and to facilitate the molding of the product to increase the productivity do.

In addition, the addition of calcium carbonate as described above, it is possible to increase the noise reduction effect according to the content of calcium carbonate, increase the mechanical and physical strength of the product to prevent deformation from impact from the outside, cold weather The effect of preventing freezing and condensation in summer can be achieved at the same time.

And the content of the above calcium carbonate can be added up to 200% by weight when the combined amount of asphalt (asphalt) and plasticizer to 100 considering the molding and manufacturing cost of the product.

Inorganic fillers (such as talc, mica, magnesium carbonate, zinc oxide, etc.) may be added to reduce noise, and calcium carbonate, aluminum trihydrate, zinc borate, and the like may be added to improve flame retardant function.

In addition, the special asphalt sound insulation layer 25 formed as described above may be formed in various thicknesses. The thickness of the special asphalt sound insulation layer 25 may be better considering only the aspect of noise elimination. There is an effect of not increasing the proportional effect, and the volume of the product becomes too large and the cost of production increases, which has an effect on the availability and economics.

Therefore, it is most preferable to maintain the thickness of the special asphalt sound insulation layer 25 to 1mm ~ 20mm.

As the said flameproof layer, the flameproof pad 26 is mentioned.

Fire prevention is to prevent the combustion of flame under normal environmental conditions by chemically and physically treating combustible materials with boric acid (H3BO3) and calcium chloride (CaCl2).

Bonding the flame retardant pad 26 formed of flame-retardant pad or sheet to the outer surface of the pipe 11 formed of synthetic resin (PVC), which is a high risk of fire and combustible material (organic polymer material), and the PVC pipe fitting pipe 21 It is to protect it from fire by stacking it.

By attaching (laminating) a flame retardant pad 26 processed with a flame retardant to the outer surface of the pipe 11 formed of a combustible material and the PVC pipe fitting tube 21 as described above, giving flame retardancy, thereby preventing fire from fire. By delaying or incineration, the effect of preventing fire and fire can be obtained.

In the present invention, the ultrafine sound-absorbing layer 14, 24, the special asphalt sound-insulating layer 15, 25, and the flame retardant sheet 16, 26 on the outer surface of the PVC 11 or PVC pipe fitting 21 formed of PVC. ) (13: 13-1, 13-2, 13-3) (23: 23-1, 23-2, 23-3) is a solid adhesive and hot melt Various joining means such as adhesives, heat, ultrasonic waves, and double-sided tapes are used to integrally adhere (glue) the components that form the present invention.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

Noise and flame retardant pipe 100 with improved noise and flame retardant function according to the present invention is attached to the outer surface of the pipe (11) formed by the improvement of the cylindrical tube using PVC, as illustrated in FIG. 1, 13-2, and 13-3), the ultrafine sound-absorbing layer 14, the special asphalt sound insulation layer 15, and the flameproof sheet 16 were sequentially stacked to form a single body.

Further, pipe fitting pipes (2: straight connection pipe fitting pipes 2-5, right angled bending pipe fitting pipes 2-1, 45 degree bending pipe fitting pipes 2-2) as illustrated in FIGS. 2A to 2E. A branch pipe type pipe fitting pipe (2-3) and a square branch pipe fitting pipe (2-4) are shown in FIGS. 6A and 6B to improve noise and flame resistance according to the present invention. In the molding (manufacturing) was formed as follows.

The inner and outer surfaces of the PVC pipe fitting tube 21 formed using PVC are integrally formed with the inner surface sound insulation layer 22-1 and the outer surface sound insulation layer 22-2 as a mineral sound insulation layer 22. A connection end 28 was formed by covering (covering) the inner and outer surfaces of the flange 21-4 and the connection end with the inner surface sound insulation layer 22-1 and the outer surface sound insulation layer 22-2. The threaded portion 29 was formed on the outer surface of the end 28, and the flange 21-1, the connection end 21-2 and the threaded portion 21-3 on the other side were exposed to the outside as it was formed of PVC. .

Of course, the inner and outer surfaces of the flange 21-1, the connecting end 21-2, and the screw portion 21-3 may be covered with the inner surface acoustic sound insulation layer 22-1 and the outer surface sound insulation layer 22-2. Can be.

As described above, the outer pads 23: 23-1, the outer surface of the inner sound insulating material layer 22-1 and the outer layer of sound insulating material layer 22-2 laminated (covered) on the inner surface and outer surface of the PVC pipe fitting 21 23-2, 23-3) was used to form an ultrafine sound-absorbing layer 24, a special asphalt sound insulation layer 25, and a flameproof sheet 26 in this order.
