Hereinafter, embodiments according to the present invention will be described with reference to the drawings. However, the embodiments described below are illustrative of one preferred embodiment of the present invention, and examples of such embodiments are not intended to limit the scope of the present invention.

FIG. 2 is a perspective view showing an external shape of a sound-absorbing plate for a heating pipe according to the first embodiment of the present invention, and FIG. 3 is a sectional view taken along line A-A 'of FIG.

In this embodiment, the sound absorbing panel 100 is constituted by an upper panel 10, a lower panel 20, and a vibration panel 30 provided therebetween.

The upper panel 10 includes a first pipe line 11 for supporting a pipe installed in a first direction, that is, a transverse direction, and a second pipe line 11 for supporting a pipe in a second direction orthogonal to the first pipe line 11, And a third piping line 13 connected in an arcuate shape connecting the first piping line 11 and the second piping line 12 to each other, Respectively. Here, the distance between the respective piping lines 11 and 12, that is, the distance between the first piping line 11 and the neighboring first piping line, and the distance between the second piping line 12 and the neighboring second piping line Is appropriately set in accordance with the heating piping construction standard of the building.

The upper panel 10 and the lower panel 20 are made of sawdust or wood flour as a main component, and an appropriate binder is mixed therein if necessary. As the binder, an inorganic binder is preferably employed. Sawdust or wood flour is a by-product that is produced in the process of shredding wood or usually treating wood. The main raw material of sawdust is wood, which has the original pores of wood. When sawdust is compression molded, many pores are formed according to the compressive strength. As the compression ratio is increased, the pore size becomes smaller.

4 is an exploded perspective view of the vibration panel 30. FIG. The vibration panel 30 comprises first and second panels 31 and 32 and a vibration film 33 interposed therebetween. The first panel 31 is made of a porous material. As the first panel 31, a foamed resin foamed with organic materials such as PVC, nylon, polyester, water-based acrylic, ethylvinyl acetate (EVA), polyvinyl alcohol (PVA), polystyrene, polyurethane, Further, as the first panel 31, a foamed styrene resin (styrofoam) is more preferably employed. A plurality of hemispherical grooves 31a are provided on one side of the first panel 31. [ Here, the shape and size of the groove 31a are not limited to a specific one.

The second panel 32 may also be made of a porous material, such as PVC, nylon, polyester, aqueous acrylic, ethylvinyl acetate (EVA), polyvinyl alcohol (PVA), polystyrene, polyurethane And a foamed resin in which an organic substance such as a polyethylene resin is foamed is employed. Also, the second panel 32 is preferably a foamed styrene resin (styrofoam). A groove 32a having a size and shape corresponding to the position corresponding to the groove 31a is provided on one side of the second panel 32, that is, the side opposite to the first panel 31. [

In the present embodiment, the outer surface of the vibration panel 30 protrudes in a semispherical shape. This is for widening the contact area between the vibration panel 30 and the first and second external panels 10 and 20, and the outer surface of the vibration panel 30 can be made flat.

Also, the first panel 31 and the second panel 32 may be formed of materials having different densities from each other. The sizes of the grooves 31a and 32a provided in the first panel 31 and the second panel 32 are set to be different from those of the neighboring ones so that the sizes of the spherical grooves formed by the grooves 31a and 32a are different from each other Can be set differently.

The first and second panels 31 and 32 are formed by mixing a foaming agent with an organic material and foaming the mixture. Also preferably, a plasticizer may be added at this time. When the first and second panels 31 and 32 are foamed, it is preferable that at least two kinds of pores having different sizes are formed.

According to the study by the present inventors, when pores having different sizes are formed in a certain material, sound absorption and sound insulation functions are improved. Fig. 5 is a view for explaining the sound absorption and sound insulation functions.

In FIG. 5, reference numeral 200 denotes a porous material having a plurality of pores. The first pores 210 having a relatively large diameter and the second pores 220 having a small diameter are present in the porous material. When the sound waves A are drawn from the outside, the sound waves A are transmitted through the medium 200, And the first and second pores 210 and 220, respectively. However, when the sound wave A having passed through the first pore 210 enters the second pore 220, the sound wave A is reflected or refracted as indicated by a and b. This phenomenon occurs similarly when the sound wave b passing through the second pore 220 enters the first pore 210. This is because the resonance frequency of the pore varies depending on the pore size.

Generally, the sound insulation function of a material is determined by how much of the sound wave applied from the outside passes through it, and the sound absorption function is determined by how much the sound wave applied from the outside is absorbed. All materials are vibrated when they are stimulated by external sound waves. At this time, the frequency sounds that are affected by the vibration are absorbed through the process of conversion into vibrational energy.

As described above, if pores having different sizes are formed in a certain medium, the linearity of the sound waves is remarkably reduced as the sound waves are reflected and refracted in passing through the pores. That is, the sound insulation function is improved. The sound waves are resonated while passing through pores of different sizes. That is, the sound wave energy of various frequency bands is converted into the vibration energy of the pore, thereby improving the sound absorption function.

The vibration film 33 is made of a material that can easily vibrate due to an external impact or sound energy applied from the outside. As the vibration film 33, for example, PVC, nylon, polyester, and aqueous acrylic, ethylvinyl acetate (EVA), and polyvinyl alcohol (PVA) may be employed.

As the vibration film 33, for example, a metal material such as an aluminum thin film which can be easily vibrated by external impact or sonic energy can be employed.

As the vibration film 33, a ferroelectric film can be preferably applied. As the ferroelectric film, PVDF, more preferably a? -Phase PVDF film is employed. The ferroelectric material has a function of converting an external impact energy into electric energy when it is applied. Therefore, when the ferroelectric film is used as the vibration film 33, impact energy or sound energy from the outside is converted into electric energy and is annihilated, thereby providing a more effective effect for preventing the interlayer noise of the building.

The first and second panels 31 and 32 and the vibration film 33 are first formed as shown in Fig. 4 and then the vibration film 33 is formed on both sides of the vibration film 33 1 and the second panels 31 and 32 are bonded to each other.

In the embodiment shown in Figs. 3 and 4, the outer surface of the vibration panel 30 protrudes in a semispherical shape. This is for widening the contact area between the vibration panel 30 and the first and second external panels 10 and 20, and the outer surface of the vibration panel 30 can be made flat.

Meanwhile, in another preferred embodiment of the present invention, the lower panel 20 under the upper panel 10 is mixed with porous mineral. At this time, porous ceramics or zeolite may be preferably employed as the porous mineral.

When the compression ratio is increased when the upper and lower panels 10 and 20 are formed by compression molding of sawdust or wood powder, the size of the pores formed in the upper panel 10 and the lower panel 20 is reduced, The absorption rate can be increased while the total number of pores becomes smaller. When the compression ratio of sawdust or wood powder is lowered, the number of the pores provided in the upper panel 10 and the lower panel 20 is increased while the size of the pores is increased.

The porous ceramics typically have pores in the order of micrometers, and in the case of zeolites, have pores in the nanometer order. When a mixture of sawdust or wood and a porous mineral is used in forming the upper panel 10 and the lower panel 20, it is possible to reduce the number of pores provided in the upper panel 10 and the lower panel 20, It is possible to improve sound absorption and sound insulation functions by the upper panel 10 and the lower panel 20.

In the case of manufacturing the sound absorbing plate 100, the upper and lower panels 10 and 20 and the vibration panel 30 are formed and then bonded to each other using, for example, an adhesive. When the upper panel 10 and the lower panel 20 are formed, the sawdust or the wood and the binder are first mixed in a mixer and mixed well. In this case, the binder is mixed with, for example, 5 to 25% by weight of the sawdust or binder. Then, the upper panel 10 and the lower panel 20 are manufactured through a method of press-molding the mixture using a mold having the same shape as the outer surface of the vibration panel 30.

As a method of manufacturing the sound absorbing plate 100, the following method can be preferably employed. First, sawdust or wood and a binder are mixed to form a mixture. Then, the mixture is laminated to form a first layer for the lower panel 20, and a vibration panel 30 is laminated on the first layer. Then, a second layer for the upper panel 10 is laminated on the upper side of the vibration panel 30, and a pressure is applied to the laminate to manufacture a sound-absorbing plate.

The sound absorbing plate 10 having the above-described structure has a plurality of pores having various sizes. As described above, if pores having different sizes are formed in a certain medium, the linearity of the sound waves is remarkably reduced as the sound waves are reflected and refracted in passing through the pores. That is, the sound insulation function is improved. The sound waves are resonated while passing through pores of different sizes. That is, sound wave energy of various frequency bands is converted into vibration energy of pores, and sound absorption function is improved

Further, for example, a spherical space is formed inside the vibration panel 30, and a vibration film 33 is disposed inside the space. Here, the degree of freedom of vibration of the vibration film 33 will be set according to the size and number of spherical inner spaces.

When impact energy or sonic energy is applied from the outside, the vibration film 33 vibrates correspondingly. That is, a part of the impact energy and the sound energy is converted into the vibration energy of the vibration film 33. Since the first and second panels 31 and 32 are formed of a foamed resin having a plurality of pores in the present embodiment, the vibration energy of the vibration film 33 is mostly generated by the first and second panels 31 and 32 Absorbed and disappears.

The sound absorbing panel 100 is composed of a combination of the vibration panel 30 and the upper and lower panels 10 and 20 having different densities from each other. When sonic energy is propagated from one medium to another medium, that is, through a medium with a different density, it is scattered or reflected by the density difference between the mediums at that interface.

 2, when sound energy from the outside is propagated through the sound absorbing plate 100 according to the present invention, the sound energy is preferentially transmitted from the upper panel 10 to the vibration panel 30, 20 in the process of being dispersed and absorbed.

The upper and lower panels 10 and 20 and the first and second panels 31 and 32 of the vibration panel 30 are provided with pores having two or more sizes. Accordingly, when the sound wave energy is propagated through these panels 10, 20, 31, and 32, substantial dispersion and interference are generated, thereby enhancing sound insulation and sound absorption functions.

Particularly, when shock energy or sound energy not absorbed or sounded by the upper panel 10 passes through the vibration panel 30, the vibration film 33 provided in the vibration panel 30 vibrates in response to the energy do. That is, the impact energy and the sound energy are converted into the vibration energy of the vibration film 33. When the vibration film 33 vibrates, the impact energy and the sound energy are generated again. At this time, the frequency band of the vibration film 33 can be changed according to the thickness or material of the material constituting the vibration film 33. For example, as the thickness of the vibration film 33 is reduced and the elastic force of the material constituting the vibration film 33 is increased, the conversion frequency becomes higher.

The impact energy and the sound energy generated by the vibration film 33 are easily absorbed and removed by the first and second panels 31 and 32 coupled to both sides of the vibration film 33.

Sawdust also has very low thermal conductivity. Therefore, when the sound absorbing plate 10 is formed using the sawdust, thermal energy emitted from the heating pipes installed in the first to third piping lines 11 to 13 of the sound absorbing plate 10 is absorbed by the lower side of the sound absorbing plate 10, The transfer to the slab layer 1 of Fig. 1 is minimized. That is, the heating efficiency of the building is improved.

6 and 7, a process of constructing the heating pipe using the sound absorbing plate 10 according to the present embodiment will be described.

The first pipe line 11 and the second pipe line 12 on the sound-absorbing plate 10 are extended to be connected to those of the adjacent sound-absorbing plate 10.

7, the straight portion of the pipe 50 is disposed by using the first or second piping lines 11 and 12 of the sound-absorbing plate 10, and the third portion of the sound- And the curved portion of the pipe 50 is disposed by using the piping line 13. When the pipe line is completed, the mortar layer is formed by pouring the mortar on the upper side.

In this embodiment, the piping pipe is stably supported by the first to third piping lines 11 to 13 provided in the sound-absorbing panel 10. In particular, since the sound absorbing plate 10 has a plurality of pores having different sizes and the elasticity of the sound absorbing plate 10, the sound energy and the vibration energy propagating from the upper side to the lower side of the closed mortar layer are absorbed and blocked by the sound absorbing plate 10 do. Therefore, the problem of interlayer noise, which is a problem in buildings, is greatly reduced.

In this embodiment, the vibration panel 30 is configured with a plurality of through holes 301. The through hole 301 is for effectively coupling the vibration panel 30 to the upper and lower panels 10 and 20 when the sound absorbing plate 100 is manufactured.

That is, when the vibration panel 30 according to the present embodiment is laminated on the lower side and the upper side of the vibration panel 30 and then the mixture of the sawdust or the wood and the binder is entirely pressed, the mixture passes through the through holes 301 So that the vibration panel 30 is firmly coupled to the upper and lower panels 10 and 20.
