The present invention relates to a method for constructing an interlayer noise-proof floor structure. In particular, the interlayer noise prevention material (1) (1a) having a very advanced result of having a dynamic elastic modulus of 2.8 MN / m 3 and a dynamic elastic modulus of 1.0 MN / m 3 By using the anti-sediment mount (40) for the first time with more advanced results, the interlayer noise prevention (heavy shock sound prevention) can be dramatically implemented, so it is applicable to both wet construction as well as semi dry construction and dry construction. It has a characteristic that can achieve (heavy shock sound prevention).

In recent years, the prevention of floor noise in buildings such as apartments or villas, namely, the problem of floor noise prevention has emerged as an urgent problem to be solved so that legislation for minimizing the transmission of impact sound (light impact sound, heavy impact sound) is proposed. . To this end, related industries and related experts have devised various methods for field application, but both focus on dry and semi-dry construction. The reason why we have to focus on dry and semi-dry construction is that we have not come up with a solution that satisfies the problem of preventing inter-layer noise in wet. The reason why the weight shock sound was not solved in the wet is because it did not develop the interlayer noise preventive material and anti-sedimentation mount as shown in the present invention. In other words, most of the technologies and patents related to interlayer noise prevention that have been made up to now have been based on dry and semi-dry construction because they have not been solved to satisfy the problem of interlayer noise prevention in wet.

That is, in the dry and semi-dry constructions applied in the construction of a typical apartment or villa, first, the dry place the appropriate number of pillars on the slab (100), the barrier plate on the pillars, and again to place the pillar over the barrier plate It is a method of laying the floor structure by placing plywood, synthetic resin plates, metal plates, and wooden boards on the pillars. The semi-dry method is a method of placing a proper number of pillars on the slab 100, placing a barrier plate over the pillars and placing the sound insulation material on the barrier plate, and then pouring a finishing mortar over the sound insulation material to complete the floor structure.

However, the floor structure according to the dry and semi-dry construction described above does not apply to the concept of dynamic elasticity and anti-sedimentation for the construction of the materials used, so that only the thickness of the sound insulation board and sound insulation material is increased and space is secured. Therefore, due to problems such as construction difficulties and ineffective in the application of the site other than the laboratory, the situation of weight shock sound is not solved at all.

On the other hand, in the conventional construction as described above, because the light weight impact sound can be almost solved by increasing the thickness of the slab 100, the construction company is constructing by increasing the thickness of the slab 100, the current slab (100) ), The weight impact sound is not well resolved at a thickness of 180 mm, so the thickness of the slab 100 has to be increased to 210 mm in the future. However, increasing the thickness of the slab 100 for the purpose of solving the heavy impact sound, which inevitably leads to an increase in the construction cost, and the increased construction cost is a contradiction that the consumer must hold, and in terms of the macroscopic aspect of the construction technology It will lead to degeneration.

Therefore, the most reasonable construction method in the construction of the floor structure of multi-generation buildings is the wet floor structure construction as the present invention seeks, which is to lay the light-insulating material over the slab 100, and then poured the light foam concrete over the sound-absorbing material and then light air bubbles It is a method of finishing finishing mortar by pouring concrete and attaching floor finishing material on finishing mortar. By the way, even in the conventional wet floor construction, the problem of lightweight impact sound can be somewhat solved, but in particular, the problem of weight impact sound is not solved, and the sound insulating material laid on the slab 100 is the weight of lightweight foam concrete and the weight of the finishing mortar, hot water Due to the weight of the pipe, the weight of the finishing material, and the weight of the furniture, subsidence (flattening) occurs within a few years after construction, and eventually the light impact sound is not properly solved. It is not getting. For reference, the Korea Housing Corporation Research Institute for Housing and Urban Research 2005. Research Papers (200 pages)-Research on the development of floor structure sound recognition for joint housing / Ojin Jin-kyun and 3 others-shows the weight of 100Kg per square meter of floor. As such, the sinking of the sound insulation material is seriously occurring. Accordingly, even in the construction of a wet floor structure, a serious reality is encountered such that the construction of the slab 100 should be increased by increasing the thickness thereof. If the thickness of the slab 100 is increased, an irrational contradiction as described above may be accompanied. There is no choice but to.

In addition, the conventional sound insulation material used in the construction of the wet floor structure is not using the material applied with the excellent dynamic elasticity concept, such as the present invention does not solve the problem of interlayer noise, science that can prevent the settlement of sound insulation material It does not provide a means to solve the problem of the noise generation between floors.

That is, the above-mentioned conventional sound insulation materials are mostly unable to obtain excellent dynamic modulus of elasticity, and even if a relatively good dynamic modulus of elasticity is obtained, there is a problem that the settlement of the sound insulating material is notable because the settlement prevention means is not provided. It is a big obstacle. On the other hand, rock wool may have a low dynamic modulus of about 5MN / ㎥, but this has a problem of being used as a sound insulation material because of poor strength and toughness (toughness). And eventually sinking occurs.

For reference, consider the matters that define the relationship between the dynamic modulus and the bottom shock absorber.

Examining Article 28 of No. 2005-189 of the Ministry of Construction and Transportation, it stated that "a basic test for acquiring the floor impact sound must be subjected to a dynamic elasticity test." (Page 198)-A study on the development of floor structure sound recognition system for a common house / Oh Jin-gyun and three others-"In order to grasp the performance of the floor impact sound absorbing material in terms of vibration reduction, the dynamic elastic modulus is generally measured. The measurement method is defined in the 2003 Korean Industrial Standard (KS F 2868, Method for measuring the dynamic modulus of elasticity of flooring material for living space). Should be low and according to the results of the present inventors' research, The modulus should be obtained at least about 0 ~ 3MN / ㎥, but the sound insulation materials (interlayer noise prevention materials) that have been made up to now are not able to obtain the dynamic modulus of elasticity, and have the disadvantages such as invasion and poor walking feeling. 10 ~ 40MN / ㎥ is recommended at the level of the first, because the first problem was not able to solve the problem of the settlement of sound insulation material, and secondly, it is not relying on accurate calculation based on scientific basis This is because the technology to replace the realistic situation of making and applying sound insulation materials having a plate or three-dimensional structure could not be devised. Therefore, the use of such conventional sound insulation material is inevitably deteriorated noise prevention function between the layers, in particular, it is not possible to prevent the sinking phenomenon of sound insulation material, the efforts to solve this problem in the related industry, but until now to the present invention It is not possible to produce the anti-floor noise and anti-sediment mount.

On the other hand, the present invention is to propose a method for constructing the interlayer noise prevention floor structure using the interlayer noise prevention material and anti-sedimentation mount obtained the breakthrough dynamic elastic modulus bar, if the conventional wet floor structure construction method Unlike the present invention, the floor impact sound is applied to the above-described sound by using a non-scientific and irrational method of laying sound insulation on a slab 100 and placing a plurality of Taka-pins (iron core) on the slab 100 to fix the sound insulation material on the slab 100. -The pin is delivered to the lower floor by the sound bridge, so that the effect of mitigating the floor impact sound becomes worse, and when the lightweight foam concrete is poured, moisture penetrates between the bottom of the sound insulating material and the top surface of the slab 100 to make the sound insulating material. Pulmonary bleeding is causing. Therefore, cracks are generated in the lightweight foam concrete layer, resulting in poor floor construction.

In addition, the conventional sound insulation material does not consider the ground area and the height of the cone with the upper surface of the slab 100, unlike the present invention, many ground areas are not considered in this way much noise is transmitted to the lower floor, and A low cone height may provide stability of the support, but less space ensures that the impact sound is not mitigated, distributed, or absorbed, and the damping passage function is not secured to disperse and absorb the impact sound, thus preventing the floor impact sound from being effectively removed. It is also an important cause, and even if all of the above problems are solved, there is no mount technology that can prevent the settlement of the sound insulation material, so it is not an exaggeration to say that there is almost no solution.

In summary, the conventionally developed and known structures in general multi-family housing construction are predominantly semi-dry construction methods. That is, the plastic slab or rubber pillars are placed on the upper surface of the slab 100 with appropriate numbers, and then the sound insulation material in the form of a plate is placed thereon, the sound insulation plate is laid on it, the hot water pipe is laid, and the finishing mortar is constructed. After attaching the floor finishing material 105 on the top surface to complete the construction or place the column at the top of the slab 100, lay the block over the column and place the column again on the block and finally plywood or synthetic resin board There is also an attempt to dry the wood boards. In other words, these methods have been applied as a countermeasure when the existing wet structure does not solve the heavy impact sound, which has many shortcomings as described above, and can be relatively excellent through tests in laboratories. Companies have a problem that is difficult to adopt because it is a method that has not been officially applied at the construction site so far.

Because of these problems, the slab 100 was forced to increase the thickness of the slab 100 from 130mm to 150mm → 180mm, and subsequently increasing the thickness of the slab 100 to 210mm is almost definite. And the end is accompanied.

Therefore, the present invention is an interlayer noise preventing material (1) (1a) having a very advanced result of particularly high elastic modulus of 2.8 MN / m3, and a more advanced function of semi-permanent function with a dynamic modulus of 1.0 MN / m3. By using the anti-sediment mount (40), it is possible to realize the interlayer noise prevention (weight shock sound prevention) drastically, and propose an interlayer noise prevention floor structure construction method that can be effectively applied to semi-dry construction and dry construction as well as wet construction. It is the task.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

First, the first embodiment of the present invention will be examined.

EVA (ethylene vinyl acetate), PP (polypropylene), PE (polyethylene)-the same as below-mixed resin foamed material is less than 5 ~ 30mm thickness, Shore-C (Shore-C) ) The process of attaching the interlayer noise prevention plate 102 for walls having a strip shape within 30 degrees of hardness and attaching the lower portion of the wall 101 to the bottom edge of the entire corner where the slab 100 and the wall 101 meet by using a double-sided tape. The interlayer noise prevention plate 102 for walls in the present invention has a difference in hardness as compared with the conventionally designed, but it may be replaced with a normal foamed synthetic resin board.

Next, the mixed resin foamed by mixing the above-described EVA, PP, PE as a material and the thickness (e1) of the plate body (10b) is within 6 ~ 40mm, the upper surface of the plate body (10b) to be flat In addition, the four sides of the thomson-type concave-convex (T) is formed to be snapped into the Thompson method, the conical projection (11b) having a plurality of support legs (12b) on the bottom of the plate 10b is constant in all directions The convex protrusion 11b has a diameter a1 of 10 to 50 mm and a height b1 of the conical protrusion 11 b is 5 to 40 mm, and the support leg 12b is maintained. The length c1 is within 5 to 50mm, and the separation distance f1 of the conical protrusions 11b is based on the case where the size of the plate 10b is 1 meter horizontally or vertically. Contact rate at which the rounded vertices P2 of the slabs contact the upper surface of the slab 100 is 2 to 20%. The hardness of the whole shall be within the Shore-C hardness of 30 ± 20, and the anti-seizure mount 40 may be inserted at an appropriate location, for example, the four corners and the center. The rounded vertices P2 of the conical protrusions 11b of the interlayer noise preventing material 1a forming the openings 30 are in contact with the upper surface of the slab 100 while sandwiching the four edges in a Thomson manner so that the slab 100 The process of seating on the whole upper surface of) is performed.

Here, the conical protrusions 11b are in contact with the upper surface of the slab 100 when the rounded vertices P2 are in contact with the upper surface of the slab 100, as described above, within the range of 2 to 20%. It is important to produce by adjusting the number to be (preferably within the range of 10%),-the same applies to all embodiments below-such a contact ratio is the size of the plate 10b as described above Is calculated based on the case of 1 meter horizontally and vertically, and the contact ratio is within the range of 2 to 20% even if the size of the plate 10b is increased or decreased (preferably within the 10% range). Of course it should be. And it is important that the plate (10b) has a hardness of Shore-C (Shore-C) hardness less than 30 ± 20, if the hardness value is higher than the settling rate is low but the weight impact sound prevention action is poor and the hardness If the value is less than the weight shock sound effect is relatively good, but may cause settlement phenomenon.

By providing a conical protrusion 11b as described above, the interlayer noise prevention material 1a of the present invention can effectively absorb, alleviate, and disperse the impact sound as well as the light impact sound by maintaining the contact ratio as described above. The main reason is that, as shown in Table 1 and Tables 1-1 to 1-5, the dynamic elastic modulus is dependent on a very advanced result of 2.8 MN / m 3. And the conical projections (11b) of the present invention is formed in the appropriate number by the scientific calculation as described above to form a passage for the absorption, dispersion, and removal of sound, the number of the conical projections (11b) Even if there is a lot of heavy impact sound removal is not good, on the contrary too small number is not preferable because it will sink. Therefore, the numerical values presented in the present invention may be most preferable.

On the other hand, the interlayer noise prevention material (1a) of the present invention has a main function of removing the impact sound as described above, but in order to perform the action, the anti-sedimentation mount (40, 40 ') of the present invention will be very important. Because That is, the sinking prevention mounts 40 and 40 'of the present invention have a contact area between the fitting jaw 202 and the intermediate body 210 of the conical support leg 201 of the lower body 200 as described above. Since the most stable cone was selected while maintaining contact only within the range of 1 to 10% of the area of the bottom of the body 210, the sound bridge of the interlayer noise was almost completely eliminated and the settlement rate It is extremely insignificant and has the characteristic of maintaining its state semi-permanently, which is able to perfectly derive the action of the interlayer noise prevention material 1a.

And in the interlayer noise prevention material (1a) of the present invention was obtained that the numerical values of each part as described above can be carried out from the minimum range to the maximum range, in particular, the overall height may be more than 100mm in some cases, Such a high height may correspond to the semi-dry construction and dry construction to be described later. Therefore, the above numerical values are not necessarily limited to the present invention and may be increased or decreased in some cases, and the degree of change of the numerical values does not depart from the technical spirit of the present invention, which is eventually subject to the scope of the present invention. As a matter of course, according to the results of experiments conducted by the present inventors, the numerical ranges presented above are most preferable.

On the other hand, in the first embodiment of the present invention, as shown in the drawing, the edge of the interlayer noise preventing material 1a forms a Thompson-type concave-convex portion T so as to be connected to the upper surface of the slab 100 to be more securely connected. As a matter of course, it is also possible to maintain the state or to use the edge of the interlayer noise preventing material 1a in a straight line like in the second embodiment.

Subsequently, the interlayer noise preventing materials 1a are seated by sandwiching the four-sided edges in a Thomson manner, and then the anti-seizure mount 40 into the hole 30 formed to insert the anti-seizure mount 40 as described above. ) Is to be inserted, which will be described below with respect to the structure of the anti-sediment mount (40).

The material of the anti-sediment mount 40 is made of synthetic resin, and the conical support legs 201 having the fitting jaws 202 on the upper end of the intermediate body 210 can be inserted into the center and all directions. A lower body 200; Holes 215 are formed in the bottom to allow the fitting jaws 202 of the conical support legs 201 of the lower body 200 to be fixed thereto, and an interior portion of the space 211 for absorbing and dispersing noises. To be formed but the reinforcement ribs 212 to be formed in all directions, the reinforcement ribs 212 to form gaps 213 for the flow of sound, and between the reinforcement ribs 212 to make noise An intermediate body 210 having holes 214 for dispersing, and having holes 215 into which the fitting jaws 221 of the upper body 220 can be inserted; The fitting jaws 221 inserted into the upper hole 215 of the intermediate body 210 are composed of an upper body 220 formed with a bottom surface. It is obvious that the shape may be hexagonal or octagonal or otherwise.

And the settlement prevention mount 40 is the three-stage configuration as the present invention is most preferred, and in some cases the upper body 220 may be omitted, but in this case there is a different sound insulation plate. In addition, the reinforcing rib 212 may be removed from the intermediate body. On the other hand, the anti-sedimentation mount 40 of the present invention can be inserted into the interlayer noise prevention material (1a) so that the lower body 200 is directed to the top as seen in Figure 7 and even if the problem is functionally different None was confirmed.

Subsequently, the height of the anti-sediment mount 40 is best to be made the same as the overall height of the interlayer noise prevention material 1a, and in some cases, a height higher or lower than ± 2mm relative to the total height of the interlayer noise prevention material 1a. In particular, as described above, the contact area between the fitting jaw 202 and the intermediate body 210 of the conical support leg 201 of the lower body 200 is 1 to the area of the bottom surface of the intermediate body 210. It is important to keep the contact only within the range of less than 10%, because if the contact area exceeds 10%, it may be expected that the above-described sound vocal phenomena cannot be completely blocked.

The anti-sediment mount 40 of the present invention obtains more advanced results of the dynamic modulus of 1.0 MN / m 3 as shown in Table 2 and Tables 2-1 to 2-4. As a result of the settlement test under the conditions of 2-4, a breakthrough rate of "0" can be obtained. Therefore, when constructed according to the present invention, the interlayer noise preventing material 1a is almost completely incomplete and intact. It is possible to perform the action, and can be maintained semi-permanent life without settling phenomenon. In addition, the anti-sediment mount 40 of the present invention is to ensure the breakthrough dynamic elastic modulus as described above can be almost completely blocked sound bridge (Sound Bridge) for the impact sound.

Next, attaching the waterproof tape 52 to the entire joint line of the interlaminar noise preventive materials 1a to be edge-inserted in the Thomson method as described above, as well as the anti-sink mount inserted into the hole 30 ( The waterproof tape 50 is attached to the upper surface of the 40, and the lightweight foam concrete is attached by attaching the waterproof tape 54 to the entire corner where the interlayer noise prevention plates 102 for walls and the interlayer noise prevention materials 1a meet. When pouring 103, it is important to prevent moisture from penetrating the upper surface of the slab 100, in the present invention, in order to fix the interlayer noise preventing material 1a on the slab 100 as in the prior art. It is important to note that not using a pin is an important point. On the other hand, instead of the above-mentioned waterproof tape, the lightweight foamed concrete 103 may be poured after covering the entire upper surface of the interlayer noise preventing material 1a using vinyl or a film.

After the above process is made of the process of placing the lightweight foam concrete 103 above the interlayer noise preventive material (1a) and the process of pouring ondol pipe and finishing mortar 104 on the lightweight foam concrete (103) Naturally, if the floor finishing material 105, which is produced in various materials and forms, is finally applied, the housing becomes possible.

On the other hand, through the implementation of the present invention as described above, as a result of forming a light foamed concrete 103 layer as described above and obtained a very important result that no crack is generated in the lightweight foamed concrete 103 layer as shown in Figure 1 . On the other hand, using a sound insulation plate made of polyethylene or other synthetic resin plate, after pouring the light-foamed concrete (103) in accordance with the conventional method and dried it was found that severe cracks as shown in the photograph 2. Therefore, the conventional sound insulation board also has a limitation that severe cracks are generated on the lightweight foam concrete 103 as shown in the photograph 2, so that the impact noise removing function is poor, which causes the collapse of the lightweight foam concrete 103 layer. As a result, the floor is lacking in durability, and at the same time, the noise between floors can not be suppressed or removed as much as possible.

However, according to the construction of the present invention, such a problem can be seen that almost 100% of the disappearance, there was no settlement phenomenon of the interlayer noise preventive material (1a) or cracking of the light foam concrete (103) layer, thereby removing the impact sound Not only was this very good, but the vocal phenomena transmitted through the anti-sediment mount 40 remained close to "0", especially the settlement rate remained close to "0", and the condition lasted for more than a month. The important result is that it remains. Accordingly, the durability of the anti-sediment mount 40 of the present invention can be said to be semi-permanent, and thus the function of the interlayer noise preventive material 1a can be almost semi-permanently maintained.

Next, the second embodiment of the present invention will be examined, which is in direct contact with each other in a straight line without connecting the edges of the interlayer noise preventing material 1a in a thomson manner as compared with the above-described first embodiment. As described above, there is only a difference in the operation of the waterproof tape, and the rest of the operation and construction tips, features, and results are the same as in the first embodiment.

Next, a third embodiment of the present invention will be examined.

Unlike the interlayer noise prevention material 1a shown in the above-described first and second embodiments, the conical protrusions 11 and 11a are formed on both sides as shown in the drawing, and the upper side has a shock absorbing function. There is a slight difference that the lower part uses the interlayer noise prevention material 1 to have a shock-absorbing function. Thus, the same hardness can be separated into the shock-absorbing function and the shock-absorbing function. It can be determined according to the present invention will not have a reason to discuss in detail, the anti-seizure mount 40 is to use the same. Here, the structure of the interlayer noise prevention material 1 mentioned above is taken into consideration.

It is made of a mixed resin foamed by mixing EVA, PP, PE, the thickness (e) of the plate body 10 is within 6 ~ 15mm, and has a plurality of support legs 12 on the upper surface of the plate body 10 Conical projections 11 are to be formed continuously while maintaining a constant interval in all directions, the diameter (a) of the conical projections 11 is within 10 to 50mm and the height (b) of the conical projections 11 is 5 to When the length (c) of the support leg 12 is within 5 ~ 50mm and the separation distance f of the conical projections 11 is less than 40mm, the size of the plate 10 is 1 meter horizontally and vertically The rounded vertices P of the conical protrusions 11 are defined within a range in which the contact ratio contacting the upper surface of the slab 100 is 2 to 20%, and the overall hardness is Shore-C (Shore). -C) the filling which has a hardness of 30 ± 20 and has formed holes 30 into which an anti-seizure mount 40 can be inserted at an appropriate location. The absorption part,

The rounded vertices P1 of the conical protrusions 11a are defined within a range in which the contact ratio of contacting the upper surface of the slab 100 is 2 to 20% based on the case of 1 meter, and the overall hardness is Shore. -Shore-C hardness will be within 30 ± 20, and the settlement prevention mount (40) can be inserted at the appropriate place. It is made by combining the shock-absorbing portion forming the holes 30, and when applied to the construction as shown in FIG. 8, the shock-absorbing portion, that is, the conical projections 11 are directed upward and the shock-absorbing portion, that is, the conical projection ( 11a) make contact with the top surface of the slab 100. However, the results of the experiment obtained that the position can be reversed.

This third embodiment of the present invention also reveals the same operation and features, construction tips, results, etc. when compared with the first and second embodiments described above, which is the construction layer 1 as shown in Figure 8 There is a difference that the anti-sediment mount 40 penetrates the hole 30, and before placing the lightweight foam concrete 103, another surface on the upper surface of the interlayer noise preventive substance 1 and the anti-sediment mount 40 After placing the sound insulation plate 106 made of synthetic resin and taping using a waterproof tape as described above, the construction of the lightweight foam concrete 103 prevents moisture from penetrating into the upper surface of the slab 100. There is a difference. That is, the interlayer noise prevention material (1) of the present invention is to form a concave protrusion (11) (11a) is formed up and down symmetrically as shown in the drawings, the attenuation passage should be formed on the upper and lower sides based on the plate (10) Therefore, the sound insulating plate 106 is placed on the upper surface thereof, so that the interlayer noise prevention material 1 does not settle when the lightweight foam concrete 103 is poured in this way, and the interlayer noise prevention material 1 as shown in FIG. This is because an attenuation passage is formed above and below).

On the other hand, it is only natural that the interlayer noise preventing material 1 used in the third embodiment of the present invention can also be used as the first embodiment by forming the thomson type unevenness (T). I will not.
