The present invention relates to an elastic spring, and more particularly, to a spring and an interlayer noise material using the same, which are superior to conventional springs for vibration, sound, and shock absorption.

The spring of the present invention can be said to be a kind of mechanical element that absorbs and accumulates energy using elastic deformation of an object to act as a buffer.

As well as residential spaces such as houses and apartments, springs and dustproof materials are used in various fields such as general office buildings or factory buildings for the purpose of shock absorption, dustproofing, and noise blocking. However, the construction or equipment for shock absorption, dustproofing, noise blocking, etc. are very expensive and require high technology. For example, anti-vibration rubber or anti-vibration equipment is very expensive compared to the construction of general building equipment, and there is also a problem in sustainability. For example, the anti-vibration rubber has a problem that its anti-vibration performance is reduced in proportion to the use time.

In addition, semi-permanent dustproof facilities or noise isolation construction are currently residential spaces. In the case of apartments, many attempts have been made to reduce noise between floors to provide independent space for each household, but the cost is high and the height of each floor is increased. There is a limit to the height of the building as it must be high.

As a conventional elastic spring, a spring or a coil spring using an elastic body such as general rubber or silicone is in a straight line in the direction of force F, and only an elastic effect corresponding to the elastic modulus of the elastic body itself can be obtained. In addition, it absorbs shocks, but also prevents vibration and noise, and can only obtain a protection effect within the range of the inherent elastic springs.

Therefore, the inherent elastic ability of the elastic body is very important because it relies only on the elastic force of the elastic body itself and expensive good elastic body should be used.

The present invention is to solve the problem that depends only on the elastic capacity of the conventional elastic spring or the elastic body as described above, it is an object to provide a new elastic spring to effectively prevent noise, vibration, and the like as a simple structure.

Elastic spring according to the present invention, a relatively large specific gravity rigid body; And an elastic body having a specific gravity smaller than that of the rigid body, wherein the rigid body is in contact with the elastic body so that a load, vibration, noise, or impact from the outside is alleviated at the contact portion.

In addition, the other one of the rigid body or the elastic body is arranged in a line on both sides.

In addition, the rigid body is a sphere or ellipsoid; Sharp parts formed on both sides of a column having a circle, ellipse, or polygon in cross section; Or a polyhedron including tetrahedron, hexahedron or octahedron;

The elastic bodies are disposed at both ends of the rigid body, and the shape of the elastic body is deformed so as to radially open at both ends of the rigid body by an external load.

In addition, a rigid body having a pointed end at one or both ends; And an elastic body corresponding to the end shape of the rigid body, the elastic body having the receiving portion coupled to the sharp end of the rigid body; and the elastic body radially based on the pointed portion of the rigid body by an external load. The shape is deformed so that it opens.

In addition, as an example utilizing the elastic spring of the present invention can be used for building floor insulation, the insulation, the hole in which the elastic spring is accommodated; Two pairs of ends corresponding to each other; And a support part formed at a bottom of the heat insulator and stretched according to a load applied to the heat insulator.

The concept of the elastic spring of this invention is demonstrated first.

In Figure 1 below, for example, when a ball weighing 100 grams is thrown directly into the wall, the force of the ball is placed in line with the wall and acts.

[Figure 1]

In other words, if the ball is loaded with a random value of 100, if the ball hits the wall vertically in a straight line, the entire force of 100 will be transmitted to the wall, but as the ball below hits the wall at an angle of 45 degrees The energy delivered to the wall is reduced to 50. As such, when the angle hitting the wall with respect to the direction of movement of the force changes, the amount of impact force applied to the wall also changes. By this principle, if the spring is distributed to the side instead of being transmitted in a straight line, the shock absorption rate, that is, the spring can be made more efficient.

In Fig. 2, elastic bodies such as elastic springs on the left side and rubbers or silicones on the right side are applied to the compression springs or elastic bodies as they are, and forces accumulate inside the straight springs or elastic bodies. do. The force (F) exerted on the intrinsic elastic capacity of the elastic body only changes the amount transmitted to the floor. Therefore, the elastic capacity of the elastic body is very important and if the elastic capacity is weak, a lot of force or impact is transmitted to the floor.

[Figure 2]

In Figure 3 below, a rigid body is placed on the bottom in the shape of a pointed triangular pyramid, and a groove is formed on the rigid body so as to correspond to the shape of the rigid body, and is placed on the rigid body, and the force F acts vertically. Fig. 3 (a), Fig. 3 (a), 3 (b) showing the transmission of vibration waves or sound waves, and a material having a high specific gravity in the middle, and a vibration wave in a rigid body and an elastic body bonded to the top and bottom of the rigid body. 3 (c) is shown to indicate that sound waves and the like are acting.

First, when the same force F as shown in Fig. 2 is applied to the elastic body in Fig. 3 (a), the force applied from the upper side by the angle of the rigid body is dispersed sideways and accumulated. In other words, since the force applied from above acts at a different angle in a straight line by the angle of the floor where the force acts, the amount of force applied to the floor is reduced by the distributed force. That is, in addition to the inherent elastic capacity of the elastic body, the force transmitted to the floor by the dispersion of the force due to the deformation of the angle is further reduced.

In FIG. 3 (b), the vibration wave applied through the elastic body is reflected at the interface between the elastic body and the rigid body and cancels each other. In particular, the wavelength of such a vibration wave is very effective at 1 KHz or more.

In Figure 3 (c), the vibration wave applied through the elastic body on the upper side is applied to the vibration wave applied in the upper elastic body so that the vibration wave applied from the elastic body is not shaken by the law of inertia. . That is, it is reflected by the difference in medium and the difference in specific gravity. This phenomenon occurs between the rigid body and the elastic body below, so that the vibration wave transmitted as a whole becomes small. Such attenuation is effective at high frequencies above about 200 Hz.

[Figure 3]

Figure 4 below is a more detailed illustration of Figure 3 (c). In Figure 4, a spherical rigid body is connected between Spring A and Spring B towards the wall. When a force is applied to the spring A, the spring A vibrates and the vibration is applied to the rigid body, and the vibration is transmitted to the spring B through the rigid body. At this time, the vibration applied to the spring A is transmitted to the spring B in inverse proportion to the specific gravity of the rigid body located in the middle. The smaller the specific gravity of the intermediate rigid body is, the more vibration is applied to spring A to spring B.

[Figure 4]

In Fig. 5, when the force (F) is applied to the elastic body on the bottom of the object on the left side, the object passes through the elastic material and the force acts on the floor. Will be delivered to The object on the right is in the form of an iron rod like an awl, which distributes the force of the elastic body sideways at the angle of the awl, so that the force applied from above is not directly transmitted to the bottom surface, but is more accumulated by the elastic deformation in the left and right directions of the elastic body.

[Figure 5]

That is, in Fig. 5, the object on the left side directly exerts a force on the elastic body in a large area, thus acting as an elastic body by absorbing the force of the elastic body itself, and transmitting the remaining force to the floor. However, an object such as an awl on the right side absorbs much force through deformation in the radial direction even when the same force is applied, so that even the same elastic body transmits less force to the bottom than the elastic body on the left side.

As described above, when the general elastic body is used as it is, only the inherent elastic force of the elastic body can be exerted. Therefore, the present invention not only has an additional elastic force in addition to the inherent elastic force of the elastic body, but also deforms the shape so as to further disperse noise, vibration, shock, and the like. That is, as described above, the elastic spring according to the present invention is formed by coupling a corresponding elastic body to accommodate the sharp shape of the rigid body to a rigid body having one or both ends having a sharp shape. Thus, the elastic spring causes the elastic body to spread radially with respect to the axis when it is subjected to forces or impacts on the pointed shaft so as to distribute the force or impact from the rigid body. In other words, in addition to the inherent elastic deformation capacity, the elastic body can further disperse a force or impact as a change in shape.

The elastic spring according to the present invention may be used as one rigid body and one elastic body. However, in order to absorb shock waves, noise and vibration, it is preferable to work with an elastic body in two parts of the rigid body.

With reference to the drawings will be described in more detail with respect to the elastic spring of the present invention.

1 is a cross-sectional view showing an example of an elastic spring according to the present invention.

FIG. 1A illustrates a rigid body 120 having a higher specific gravity between two elastic bodies 110. FIG. 3 is a diagram conceptually illustrating an elastic spring 100 using an elastic body 110 such as rubber or silicon and a rigid body 120 such as a metal, glass, or ceramic material having a larger specific gravity than the elastic body. In FIG. 1A, the general elastic body 110 is attached to the upper and lower surfaces of the elastic body 120 to maintain the equilibrium and maintain the circular shape, and thus the direction of the force F is in a straight line. The elastic effect corresponding to the elastic modulus can be obtained, and it is effective to reduce vibration or noise by reducing the vibration or sound wave transmitted to the floor by absorbing or reflecting the vibration wave or sound wave described in Figs.

FIG. 1B is a further improvement of FIG. 1A, in which the intermediate rigid body 120 is changed into a spherical shape. In FIG. 1B, the elastic bodies 110 are respectively coupled around the intermediate rigid body 120 so that when the force F is applied from above, the elastic body 110 has the force toward the rigid body 120 as the ends thereof are radially opened. By absorbing this, the elastic force is improved beyond the original elastic ability, and as shown in FIG. 1A, the wavelength of vibration waves or sound waves is canceled or reflected, thereby exhibiting the effects of vibration and noise blocking.

Figure 2 is a cross-sectional view showing another example of the elastic spring according to the present invention is an example that can further improve the performance, such as elastic force and vibration absorption than Figure 1.

The elastic spring of Figure 2 is composed of an elastic body 110 is coupled to the top and bottom on the basis of the rigid body 120 of the pointed shape of the top and bottom of the center. Fig. 2A shows a state before each part is separated and joined, and Fig. 2B shows a state where each part is joined. 2c shows that the elastic body 110 is deformed by applying a force up and down to the elastic spring 100 according to the present invention.

As shown in Fig. 2, the elastic spring according to the present invention accommodates the pointed portion as a rigid body 120 having a columnar shape (a kind of weight) having a pointed portion up and down, and a general elastic body such as rubber silicone. The receiving portion 112 is formed by the coupling of the formed elastic body 110 to be able to.

When the elastic force 100 is applied from above, the elastic spring 100 corresponds to the angle of the point where the end portion 111 of the elastic body 110 is sharp at the pointed portion of the rigid body 120 of the solid pillar as shown in FIG. 2C. When it is dispersed (radially) and accumulated in the elastic body 110 and the force applied from the above is reduced or disappears, it returns to the straight line as shown in FIG. 2B.

In the case of the external force or the impact applied to the shock wave in FIG. 2, the weight of the heavy solids (metal, stone, glass, ceramic, etc.) is increased by increasing the density of the intermediate solid in the medium. The wavelength hits and reflects off the 45-degree surface of the dense intermediate rigid column, offsetting the other wavelengths and reducing the amount of energy transmitted down. The higher the frequency, the better the effect. In addition, since sound is a kind of wavelength, the same or similar noise blocking effect occurs when transmitted through an object. Therefore, in the case of the noise between floors, such as apartments, not only shock waves but also sound waves are reduced in the same or similar manner. The rigid body 120 may be used, such as a pillar of about 10-20mm in diameter and may have a hexagonal rod or other shape. However, it is only necessary that both ends are pointed, and the angle of the pointed part may be about 30-75 degrees. If the angle of the pointed portion can be deformed as necessary, the sharpness of the elastic body is less radially spread, if the dull conversely, too much shock wave or force transmission can be transmitted according to the design of the required spring do.

1 and 2 are examples of the elastic spring of the present invention, Figure 1b is that each end of the elastic body surrounds the rigid body may be used by changing the rigid body to the spherical shape of Figure 1b in the elastic spring of Figure 1a. In this case, the elastic spring has an effect of adding additional elastic ability while the elastic body is locally deformed as shown in the right side of Fig. 5 by external force in the point contact between the elastic body and the rigid body. It also has the effect of blocking the transmission of vibration and sound waves.

In addition, when the lubricating oil is coated or coated on the surface where the rigid body and the elastic body contact with each other in FIGS. 1 and 2, the deformation of the elastic body may be easier, and the blocking effect of the vibration wave may be increased. .

Figure 3 is a cross-sectional view showing another embodiment of the elastic spring according to the present invention is an example in which the rigid body 120 and the elastic body 110 is permanently coupled. Forming a hole 125 in the middle surface of the conical pillar-shaped rigid body 120 and forming a mold to pour the liquid-like elastomer to prevent the departure of the elastic body 110 and the conical pillar-shaped rigid body 120 Can be.

4 is a cross-sectional view showing that the positions of the rigid body 120 and the elastic body 110 are reversed in the example of FIG. 2 and 3, if one rigid body 120 is used for two elastic bodies 110, in the present embodiment, two rigid bodies 120 are arranged in one elastic body 110 according to a change in position. As used, two of the rigid bodies 120 of the example of FIG. 3 are divided in half. However, the corresponding relationship between the pointed portions of the rigid body 120 and the elastic body 110 is equally applied. In the present embodiment, the elastic body 110 is disposed between the upper and lower rigid bodies 120 to correspond to the pointed portion. The two rigid bodies 120 each have a hole 125 and may be molded by pouring an elastic body as shown in FIG. 3 using a mold to prevent departure.

In the embodiments of FIGS. 3 and 4, the elastic body in the liquid state is poured and bonded. However, since the elastic body itself has some bending or bending property, holes are formed in the rigid body and protrusions corresponding to the holes are formed in the elastic body. It can also be combined by fitting without using a frame. Since the elastic spring according to the present invention is operated by the interaction between the rigid body and the elastic body, even if individually made and combined as shown in Figure 2, the same application can be applied even if used separately by using a hole in the use portion. 3 and 4, although the permanent coupling method is convenient for use, the elastic spring as shown in FIG. 2 may be sufficiently used according to the use purpose of the elastic spring.

Figure 5 is a perspective view showing another embodiment of the elastic spring according to the present invention, Figure 5a is a perspective view of the coupled state and Figure 5b is a perspective view showing a state in which a force (F) is applied from above. In the example of Fig. 5, the elastic springs of Figs. 2 to 4 form a cut part (slit) cut in advance in the portion of the end portion 111 of the elastic body so that the elastic body is easily deformed radially. In FIG. 5B, the end 111 is spread more radially along the cut 114 to be deformed to absorb or disperse more external forces, shocks, sound waves and energy. In the example of FIG. 4, the cut portions 114 may be formed at both ends of the elastic body.

The elastic springs produced as described above (springs using elastic bodies and rigid cones) may be used in the same manner as the existing springs.

6 is a cross-sectional view showing still another example of an elastic spring according to the present invention. In FIG. 6, the rigid body 120 is divided into two parts, and each of the rigid bodies 120 is coupled to the elastic body 110. Each of the rigid bodies 120, which are coupled to each other, has a structure in which bolts and tabs that are complementary to each other are formed to be used. This example is useful when the elastic body is permanently bonded to the rigid body 120 as shown in FIGS. 3 and 4. Instead of the holes 125 of FIGS. 3 and 4, the elastic body 110 is poured into a liquid state to be molded. If so, the protrusions 127 are formed to be firmly coupled to each other. When the protrusion 127 is formed in a screw form and a screw thread corresponding to the elastic body 110 is formed therein, the rigid body 120 and the elastic body 110 may be coupled by screwing without forming and coupling in a liquid state. Of course.

In the example of FIG. 6, the cutting part 114 may be formed in the same manner as in FIG. 5. In this case, after the rigid body and the elastic body are combined, the cutting body may be cut by cutting the elastic body with a knife or the like. 3 and 4 can also form a cut after coupling. That is, as shown in the contact surface of the cone and the tab to form a corresponding thread can be easily removable.

You can also make the bolt nut in the center of the cone so it can be easily separated up and down.

If only a conical column is made, it can be easily made by pouring and molding a liquid elastomer.

7 is a view showing an example of using an elastic spring according to the present invention.

In FIG. 7, the elastic spring according to the present invention allows the elastic body 110 to have a large area and inserts a plurality of rigid bodies 120 in an n × m arrangement between the two elastic bodies 110. Can work.

At this time, the intermediate rigid bodies 120 are coupled by separate coupling members 150.

The coupling member 150 may be coupled to each other in the form of a mesh or wire mesh. Alternatively, the rigid bodies 120 may be connected and coupled by forming and inserting an insertion groove in the middle of a plate made of a material such as a separate plastic.

Such an elastic spring can be used as a pad for vibration prevention by placing it under a mechanical device, a leg, a chair, or the like. At this time, the elastic spring according to the present invention can be used by reducing the size of the rigid body and inserting between the elastic bodies to reduce the actual play (movement distance) as the elastic spring. Thus, in addition to the elastic ability of the original elastic body, the elastic force and the vibration preventing ability according to the deformation of the elastic body are further improved.

8 is a perspective view illustrating an example in which the rigid bodies of FIG. 7 are coupled by a coupling member.

In FIG. 8, the rigid bodies 120 are inserted into coupling members 150 such as a plate having a wide surface, and thus, the rigid bodies 120 are combined with the rigid bodies 120 of FIG. 7. By inserting the rigid body 120 coupled between the elastic body 110 having a wide surface as shown in Figure 8 it is possible to use the elastic spring according to the invention in the form of a plate.

 The rigid body may have a pointed portion formed on both sides of a column having a circle, an ellipse, or a polygonal cross section, and may have the pointed end as a polyhedron such as a hexahedron or an octahedron with long and sharp ends. Also, the vertical cross section may have an egg shape in the shape of an oval round shape. The elastic body preferably has a receiving portion having a polygonal, circular or elliptical shape corresponding to the shape of the rigid body on the basis of the cross section perpendicular to the direction in which the force is applied. However, as described above, the elastic body does not have to have an accommodating portion, and the elastic body and the rigid body make point contact as shown in the right side of Fig. 5 above, and if the elastic body deforms due to external force, the elastic body is sufficiently existing. In addition to the elastic capacity of the elastic effect due to the deformation of the elastic body is improved. Therefore, as shown in Figs. 7 and 8, only the deformation in the local region of the elastic body itself can be expected to sufficiently improve the elastic ability and the vibration or noise prevention ability.

In the above examples, when the rigid body uses a metal where corrosion occurs (for example, iron), it is preferable to perform an antirust treatment on the surface of the rigid body.

As the elastic spring according to the present invention can be used as an interlayer noise material in a building such as an apartment, an application example of the elastic spring of the present invention will be described below.

9 is a sectional view showing the general structure of the apartment floor. This general structure is formed by the following construction. The construction order is first 1) foaming cement (220) using the heat insulating material to the insulation work while the construction on the base 210, the cement curing takes about 3 days after the construction. And 2) lay the wire mesh 230, etc. on the foam cement 220 and lay the Excel pipe 240. At this time, the Excel pipe is fixed to the wire mesh 230. 3) Then, 50 ~ 80mm of cement is poured to form a heating conductive layer 250 and the cement is cured for about 3 days. And 4) the finishing plastering 260 to adjust the horizontal and height. And finally the floor finishing material 270 is constructed. Such a conventional floor structure is easily transferred down when impacted from above.

10 is a cross-sectional view showing a floor structure using an elastic spring according to the present invention. FIG. 11 is a perspective view of the heat insulating material of FIG. 10. FIG. 12 is a cross-sectional view showing a state where a load is applied to the heat insulating material. Fig. 13 is a cutaway perspective view showing that the cement is placed or the flooring material is installed on the heat insulating material. 14 is an enlarged cross-sectional view showing an enlarged portion of an elastic spring operating in the floor structure.

Hereinafter, a bottom structure using an elastic spring according to the present invention will be described with reference to FIGS. 10 to 14.

First, the operation is made to flatten the base end 310 in FIG. The flattening can be performed by cement or the like. On the proximal end 310 includes a heat insulator 320, such as a styrofoam that can use the elastic spring according to the present invention, and a heating element 340, such as an excel pipe embedded in or attached to the heat insulating material. On the heat insulating material or the heating element, cement is poured about 50 mm again to form the heating conductive layer 350, and the plastering layer 360 is formed thereon, and the flooring material 370 is finally attached. In addition, a bubble-shaped heat insulating material 380 is formed at the edge of the heating panel with a predetermined width from the base end 310 to the height of the flooring material 370 or more.

As shown in Figure 11, the heat insulating material 320 is a hole for the elastic spring 100 is accommodated in accordance with the present invention, the receiving groove 322, the heat generating element 340 is accommodated, the end for the coupling of each heat insulating material 320 323, and a small support 324 in direct contact with the bottom surface.

The hole 321 is configured to withstand the load as a heat insulating material 320 with a plurality of the support portion 324 is inserted into the elastic spring according to the present invention. The receiving groove 322 is provided when a hot water boiler is inserted into a pipe such as an excel pipe, and a linear heating element may be inserted as an electric heating element, and in the case of an electric heating type such as a surface heating element, an upper portion of the heat insulating material 320. It may be attached and used. When a heating element such as a planar heating element is attached on the heat insulator 320, the receiving groove 322 may not be necessary.

The end 323 is coupled using the end 323 as shown in Figure 8 when each of the heat insulator 320 is coupled, the end 323 is required when cement is poured on the heat insulator 320 It is to prevent the down to the base end 310 in the gap that is coupled to the heat insulating material (320). Thus, even if the cement flows, it does not form a column. If the gap opens and cement enters to form a column, the vibration above can be transmitted along the cement column to the base below.

The support part 324 is formed to allow the heat insulator 320 to contact the base end 310 only by the support part 324. Thus, the load or impact on the heat insulator 320 is to be transmitted to the base end 310 through the support 324 only.

In FIG. 12, when a load F is applied to one heat insulator 320, the support part 324 becomes dull and subjected to a force. In addition, in consideration of the situation in which the worker is forced to step on the respective insulation material 320 after the insulation 320 is installed on the floor, the intensive load may directly act on one support part 324. Thus, as shown, some of the supports 324r are blunt. For example, if a force applied to a foot area of one person is 100 kgf, during the construction, such a load acts locally on a part of the heat insulator, and some of the supporting parts 324 are pressed. However, when the conductive layer 351 is formed on the heat insulator 320, an even load is distributed on the support part 324 as a whole.

FIG. 13 shows that the individual unit loads are based on the volume of the insulation layer 320 and the elastic spring 100 based on the volume of the area of about 150 mm ² and the height of 100 mm of the unit conductive layer 351 in the state in which the conductive layer 351 is formed on the insulation 320. What acts on) is shown as a cutaway perspective view. At this time, the styrofoam as a material of the heat insulating material 320 may have a size of about 500mm × 500mm. Therefore, the load acting on the unit conductive layer on the heat insulator 320 is calculated to be about 300 kg, and the load is evenly distributed on the lower support 324 through the conductive layer 351. The hole 321 has a fixing portion 325 is formed so that the rigid portion of the elastic spring 100 can be inserted and inserted, and the elastic portion of the elastic spring 100 is free of space in the elastic portion so as to be freely deformed. There is room. Since the load is distributed evenly through the conductive layer 351 to the support 324, each load has a smaller load because the load acts in inverse proportion to the number of supports per unit area. Each support needs to withstand.

The area of the support should be minimized to not transmit the noise and impact applied from the top and it depends on the density of the insulation, but it can withstand 3kg at 5% of the total reference area (150mm ² ) when it withstands 150mm ² to 100kg. Can be. Thus the support is 150 mm ² Only the weight of about 3kg per area needs to be supported.

14 is an enlarged cross-sectional view for explaining the action of the elastic spring in more detail. Assuming the weight of the worker 100kg when the support 324 is pressed down and the elastic spring is also pushed up and the A surface is touching the floor to support the load of 100kg.

When a worker installs a heating element 340 such as an excel pipe to the heat insulator 320 and places a 50 mm thick cement or the like thereon, when the support part that is directly loaded is pressed, the volume is reduced to about 30%, and when the work is finished, 150 mm Only about 3 kg of cement weight per ^two remains so that the support is returned to about 70% of its original size and this space becomes the elastic working space where the elastic spring acts after the cement is hardened.

In addition, after cement hardens, a space for the elastic spring to act is secured. At the end of the floor construction, only 3kg of weight per unit area remains, and the styrofoam legs, which had been compressed to 100kg of worker weight, return to their original volume of about 95%. Therefore, it is preferable to lengthen the support part 324 so that a return rate may be close to 100%.

A typical styrofoam insulation is about 10mm ² for medium density and 10mm in height, with a weight of 1kg on top, the volume is reduced by about 10% and can support the weight.

The support 324 is preferably to be in contact with the floor as narrow as possible or point contact, and any shape capable of such contact may be used. However, in the present example it is simply shown as a hexahedron for the convenience of mold production.

FIG. 15 is a cut perspective view of another modification of FIG. 13; FIG.

The difference from FIG. 13 is that a fixing support part 327 for fixing the elastic spring 100 in addition to the general support part 324 is provided in the heat insulating material 320 of FIG. 15 to fix the lower elastic body of the elastic spring. Instead of the fixing part 325 in the middle of the hole 321 of FIG. In Figure 13 it can be preferably used when the rigid body and the elastic body is integrally coupled, such as the elastic spring of Figure 3 or Figure 4, in the embodiment of Figure 15, of course, the rigid body and the elastic body Even if they are inserted and combined separately, there is an advantage that can be used. In the example of FIG. 13, the intermediate rigid body or the elastic body is fixed, but in FIG. 15, the elastic body or the rigid body of the lower part of the elastic spring is fixed, so that more various elastic springs can be used. The fixing support part 327 of FIG. 15 may have a "b" shape as a circumference but may be diagonally formed, and may simultaneously perform the role of the support part 324 described above and the fixing role of the elastic spring. Of course, since the important role of the fixing support 327 is the fixing of the elastic spring can be performed only the fixing role of the elastic spring without touching the floor.

FIG. 16 is a cut perspective view of still another modified example of FIG. 13; FIG. FIG. 16 further shows a support plate 390 for supporting the elastic spring 100 further below the elastic spring 100 in order to prevent the detachment of the elastic spring 100 and to facilitate its use in FIG. 13. In comparison with FIG. 13, the elastic spring 100 is inserted into the support groove 391 of the support plate 390 so that its length is lower than the support portion 324. The elastic part of the elastic spring is inserted into and supported in the support groove 391.

FIG. 17B is a cross-sectional view illustrating a cutting plane taken along the line A-A in FIG. 17A. FIG. 17C is a cross-sectional view illustrating a cutting plane taken along line B-B in FIG. 17A.

The insulation 320 has a receiving groove 322 through which the hot water pipe can pass is formed in a lattice type with a predetermined depth. In addition, the hole 321 for receiving the support is evenly distributed so as not to overlap with the pipe receiving groove 322. Where the grid receiving grooves 322 meet is treated with a curved portion 382 to facilitate the curved piping of the pipe. In addition, the receiving groove 322 has a fixing groove 381 deeper than the depth of the receiving groove 322 is formed in a direction perpendicular to the path direction of the receiving groove 322.

The heat insulating material 320 is preferably made of styrofoam or other heat insulating material by injection molding or plastic working so that the hole 321 and the receiving groove 322 are formed. The accommodation groove 322, the fixed groove 381, and the curved portion 382 is to be able to use the existing heating pipes such as Excel pipe, copper pipe, stainless steel pipe as it is. Although the receiving groove 322 is formed in a lattice manner as shown, not all the receiving grooves 322 are used for piping, but the receiving grooves 322 may be used in the zigzag direction. That is, the receiving groove 322 is provided in a lattice type for the convenience of piping. In addition, the curved portion 382 is a space for bending or bending a pipe, and is not necessarily required for the heat insulating material 320. In addition, the fixing groove 381 is for further fixing the pipe piped to the heat insulating material 320 of the present invention, the pipe by the cement or other filling material filled in the hole 321 or the heat insulating material 320. For further fixing.
