Description

Dry ondol floor for floor shock sound prevention in apartment houses and construction method

The present invention relates to an on-floor floor for blocking the floor impact sound of a multi-family house, and more particularly, by improving the installation structure of the on-floor floor layer on the concrete floor slab for indoor floor heating, as well as significantly reducing floor noise. A structure of this excellent dry ondol floor and its construction method are provided.

In the case of multi-unit buildings such as apartments, townhouses, and multi-family houses, the airborne sound is blocked by the concrete slab structure, but the impact or vibration caused by human walking or falling of objects, such as floor impact sound, is directly on the floor. When applied, it hardly attenuates and becomes a solid propagation sound, and the floor slab is flexibly vibrated and its vibration is radiated negatively in the air, which is transmitted to the lower or adjacent generation.

These floor impact sounds are light impact sounds that generate a lot of high-frequency components, such as sounds coming from the floor directly due to impacts on the floor when a small object is dropped and the chair is moved. Heavy impacts are classified as heavy impact sounds that produce a lot of low frequency components, such as those sounding directly downstairs.

Recently, the government of the Ministry of Land, Infrastructure and Transport (MOT) set a standard for preventing inter-floor noise between apartments in response to the increase in damages such as neighboring disputes caused by the noise between floors of apartments, which became a serious social problem and the increase in civil complaints. In addition to the five standard floor structures to reduce the floor noise of multi-unit houses, the floor shock sound insulation performance rating standard as shown in Table 1 has been announced, and only products with a certain quality specified in this standard can be applied at construction sites. It is limited.

In addition, the floor of a residential building is mandatory to install insulation materials to increase efficiency and prevent heat loss during cooling and heating according to the "Rules for Facility Standards of Buildings". The floor slab and the temperature floor layer are subject to construction constraints that must meet both thermal insulation and interlayer noise blocking regulations to prevent heat from being transferred to the bottom of the interlayer structure.

On the other hand, the ondol floor structure of the building is divided into wet and dry. The wet structure is an improvement of the traditional ball structure, and the heat storage performance of the floor is good and structurally strong, but the construction period due to the formwork, concrete pouring and curing Due to problems such as delays and maintenance, it is recently being replaced by dry structures.

In short, the dry on-floor floor structure does not require concrete pouring and curing time, so it can shorten the air, and unlike the wet on-floor structure, there is no site-specific difference due to the volume change depending on the moisture content and temperature of the concrete. It is possible to achieve the most important construction cost reduction, air shortening, and standardization of quality, such as securing uniform and precise construction quality.

However, conventional dry on-floor floor structure generally generates solid wave sound from the heat storage top plate, and this solid wave sound is transmitted to the lower layer in the form of airflow sound through the space between the top plate and the bottom slab to satisfy the interlayer noise prevention standard. There is a structural limitation.

Accordingly, the present invention has been disclosed in the dry on-floor floor structure and its construction method for reducing the floor noise of the multi-unit apartment jointly completed by the present inventors, this is a dustproof, etc. on the floor slab Arrangement at regular intervals is very difficult and difficult, and the construction cost is too high and there are limitations in floor impact sound due to the structural conditions in which several components are stacked sequentially. In use, the physical properties of the dustproof and heat conductive plates are very severe, resulting in a significant drop in durability and structural stability.

Particularly, Jin-gu was commissioned by the Korea Patent Testing Institute from C-Miletech Co., Ltd. (CEO Lee Jae-geun) and the aging test (70 ± 1 ℃, 168h), tensile strength change rate, elongation rate change rate, and the like by ASTM D 573: 2004. Ozone cracking by durometer hardness change (A Type), compressive permanent shrinkage (70 ± 1 ℃, 72h) by ASTM D 395: 2003 (Method B), and ASTM D 1149: 2007 (Specimen A) As a result of several tests such as tests (50 ± 5pphm, 40 ± 2 ℃, 20% elongation, 24h), various problems in quality such as cracks and deformations occur after a certain period of time. It is difficult to apply it for reasons such as deterioration of stability.

In addition, in the case of thermal conductive plates, synthetic resin and carbon black are mixed in a certain ratio, and the injection and extrusion molding are formed in an inverse 'Ω' shape having a groove portion covering the heating pipe and a flat portion covering the upper surface of the piping panel. As a result, the soundproofing and dustproofing characteristics of the floor impact sound can be improved compared to the metal heat conduction plate, but due to the narrow shape of the opening of the groove part surrounding the heating pipe, the heating pipe is inserted in the process of inserting the heating pipe on the piping panel. Both edges of the opening of the enclosing groove are pressed and the flat part covering the upper surface of the piping panel is lifted up or raised unevenly. There is a problem that must be accompanied by inconvenience.

<제1실시 예>First Embodiment

As shown in Figure 1, the ondol floor according to the first embodiment of the present invention is largely polyethylene foam 10, sound-absorbing mat 20, dustproof 30, Mg board 40, buffer sheet 50 , Heat insulation sheet 60, heating pipe 70, piping panel 80, the heat conduction plate 90 and the ocher board 100 is configured to include.

The polyethylene foam 10 covers the bottom surface of the bottom slab S and is excellent in sound absorption characteristics, and the thickness thereof is preferably 5 mm.

For example, the apparent density is 22 (kg / ㎥), compressive stress is 3.0 (N / ㎠) at 25% deformation, tensile strength is 31 (N / ㎠), elongation is 77 (%), and average temperature is 20 ° C. Can be used that has a thermal conductivity of 0.056 (W / m · K) or more.

In the first embodiment of the present invention, a high-density PE foam was produced and sold in Shinhan Synthesis of Giheung-gu, Yongin, Gyeonggi-do.

The sound absorbing mat 20 is placed on the polyethylene foam 10, and is formed of a polyester-based synthetic resin to have a porous shape, for inserting and installing the dustproof outlet 30 at predetermined intervals and patterns. A plurality of dustproof holes 25 are formed.

The sound-absorbing mat 20 has a continuous pores therein, the sound absorption is good in the middle / high range, the thickness is preferably used that is 35mm, and the dustproof holes 25 are preferably formed at 600mm × 300mm intervals. Do.

In the first embodiment of the present invention adopted the product name Artron produced and sold by B & B in Gwangju, Gyeonggi-do.

The anti-vibration opening 30 is inserted into the anti-vibration openings 25 formed in the sound absorbing mat 20, and as shown in FIG. 2, absorbing and buffering the shock transmitted from the upper side while maintaining the elastic force stably. In order to attenuate the vibration energy, as the shape of the jar gradually goes out toward the center, a diameter of 50 mm, a thickness of 35 mm, and a resonance hole 35 having a diameter within 12 mm is formed.

The dustproof port 30 is 44-46% by weight of styrene-ethylene / butylene-styrene (SEBS), 17-18% by weight of wood powder, 6-6.5% by weight of flame retardant, and 18-19% by weight of paraffin-based processing oil. %, 3 to 3.5% by weight of the lubricant, 3 to 3.5% by weight of the stabilizer, and 6 to 6.5% by weight of hard coal may be formed by injection or extrusion.

Here, SEBS has no cracking phenomenon due to ozone, so it keeps its physical properties stable even when used for a long time. It has excellent processability such as injection and extrusion, and the material itself has elasticity. The average particle size is 2.0 ~ 3.0㎛. This is preferred. When the particle size is larger than 3.0 mu m, material separation phenomenon is caused due to the difficulty of uniform mixing, which makes it difficult to obtain a high quality dustproof port.

In addition, when the content of the SEBS is less than 44% by weight relative to the composition content of the dustproof hole 30, the soft feeling and low buffering capacity at low temperatures, if the content exceeds 46% by weight may be inferior in toughness and rigidity.

And wood flour means a sawdust powdered wood waste or felled wood, etc. If the content of such wood powder is less than 17% by weight compared to the total content of the dustproof opening 30, it does not obtain sufficient strength, if it exceeds 18% by weight The surface may be rough and the molding may not be performed properly, or plasticity may occur in part, resulting in inferior elasticity.

And it is preferable to use a flame retardant having sound absorption while satisfying UL 94 among the items for evaluating flame retardancy. Specific examples thereof may include aluminum trihydrate or magnesium oxide.

In addition, the average particle size of the flame retardant is 2.0㎛ or less, it is preferable to use 6 to 6.5% by weight relative to the composition content of the entire dustproof port (30).

In addition, the paraffin-based process oil (ProcessOil) is used to improve the melt rate while maintaining impact resistance and hardness while increasing and reinforcing workability, flexibility (low hardness) and processability, and solid at room temperature. It is composed of colorless and odorless liquid paraffinic high-grade hydrocarbons that collect the part that does not change into a low temperature. The glass transition temperature is lowered to keep the bond between the SEBS molecules in a flexible state. Prevents damage to the material due to, and maintains the elastic force of the material.

If the content of such paraffin-based processing oil is less than 18% by weight, proper moldability may not be imparted. If the content of the paraffin-based processing oil exceeds 19% by weight, the bonding strength between materials may deteriorate, so that sound absorption may be degraded, and transition may occur to cause contamination. have.

Here, there are several types of paraffin-based processing oil of 10 ~ 800 cSt (40 ℃) according to the kinematic viscosity, it is preferable to use a high molecular weight product of 400 ~ 600 cSt in order to prevent surface migration.

In addition, there are naphthenic and aromatic oils, but paraffin-based oils that are excellent in terms of discoloration contamination and odor characteristics are most preferred.

And the lubricant is to prevent the damage of the material due to mechanical friction during the processing of the dustproof port 30, to reduce the voids between the materials, to maintain the elastic force of the material, specific examples of low molecular weight polyethylene wax (polyethylene wax) and The same thing can be mentioned.

If the content of the lubricant is less than 3% by weight relative to the total content of the dustproof port 30, the performance may not be properly exhibited. If the content of the lubricant exceeds 3.5% by weight, the binding force between the materials may be deteriorated and the sound absorption performance may be lowered.

And the stabilizer is to prevent the decomposition and separation of the material due to the instantaneous heat generated by the friction between the materials and mechanical kneading, specific examples include an antioxidant such as butylhydroxytoluene (Butylated Hydroxytoluene).

The amount of the stabilizer is preferably used 3 to 3.5% by weight relative to the content of the composition of the dustproof hole (30).

And hard coal (calcium carbonate, CaCO3) is to reinforce the strength of the dust barrier 30 to maintain the dimensional stability and prevent aging by the balance of hardness and physical properties during injection and extrusion molding, the average particle size is 0.2 ~ 0.8㎛ It is preferable to use what is.

If the content of such hard coal is less than 6% by weight relative to the total content of the dustproof port 30, desorption may occur between the materials or the pores may be broken to obtain sufficient strength required as the dustproof port 30, and 6.5% by weight. If it exceeds the proper shape, such as not properly formed, not only the strength of the finished product is too strong, but also the disadvantages of easily broken and the surface of the marvelous part of the use of the use, as well as the sound insulation or sound insulation can be reduced. .

As shown in FIG. 2, the dustproof port 30 has a light weight transmitted from an upper layer because only the lower edge portion thereof is directly in contact with the bottom slab S by the resonance holes 35 formed up and down in the center thereof. In addition to dispersing and attenuating impact sounds and heavy impact sounds, vibrations are effectively dispersed and reduced first due to the morphological characteristics of a circular jar shape that is bulging toward the center of the stomach.

In another embodiment of the anti-vibration port 30 ', as shown in FIG. 3, the thickness is 35 mm, the hardness is 31 to 33 h, and a resonance hole 35 is formed in the center thereof, and the outer surface circumference is formed. There may be a plurality of deformation guide grooves 37 are formed at predetermined intervals, and may be installed at intervals of 600 mm × 300 mm with other adjacent dustproof holes. It can be mass-produced by extrusion molding method due to its morphological characteristics in which a plurality of deformation guide grooves 37 are formed on the outer circumferential surface of the cylinder, so that productivity is higher than that of injection molding, and uniformity of quality can be achieved. When it receives vertical load, it naturally deforms and induces dispersion and change to horizontal load, so that the impact force applied to the floor can be more effectively absorbed and buffered.

Mg board 40 is laid on top of the sound absorbing mat 20, and placed on top of the sound absorbing properties, excellent sound insulating properties, the thickness of 12mm is preferably used.

For example, the sound insulation characteristics are obtained by mixing 3 ~ 5wt% of sawdust, 3 ~ 5wt% of pearlite and 70 ~ 75wt% of magnesium (Mg) ore powder and mixing 15 ~ 20wt% of binder and drying it. Of course, the rigidity and ductility can be obtained, fireproof, waterproof, soundproof performance, and can effectively block the moisture due to condensation of the heating pipe (70).

The cushioning sheet 50 is laid on the Mg board 40 and laid on top of it, and formed in the form of polyester foam or non-woven fabric, which is excellent in cushioning as well as sound absorption, flame retardant, and flame resistance, and uses a thickness of 5 mm. This is preferred.

The cushioning sheet 50 prevents amplification of the solid vibration sound by performing a role and a function to alleviate the impact by sandwiching between the high density hard plate and the plate at the same time as the sound absorbing effect.

Insulation sheet 60 is laid on top of the cushioning sheet 50, stacked on top of, the silver foil layer is formed on the surface of the material, such as PE form or styrofoam, has a low elastic modulus and excellent insulation and sound absorption, the thickness is 5mm This is preferred.

The thermal insulation sheet 60 prevents amplification of the solid vibration sound by performing a cushioning function and a function between the high density hard plate and the plate at the same time as well as the heat insulation function and sound absorption.

Piping panel 80 is installed on the insulating sheet 60 to maintain the heating pipe 70 arranged in a predetermined form, the pipe fixing groove to pipe the heating pipe 70 in a predetermined pattern by a molding method such as injection. It is formed so as to have (85).

As a preferred embodiment of the piping panel 80 in the present invention, the present inventors jointly participated in the development, by employing the heating panel disclosed in the Republic of Korea Patent No. 10-0656921 to strengthen the durability of the ondol floor layer as well as construction Can greatly improve the work efficiency.

The pipe panel 80 protects the heating pipe 70 and at the same time performs a heat insulating action, and scatters and reflects loads and impacts and external noises applied in the various directions to appropriately distribute the heating pipe 70. Heat is generated evenly throughout the convection through the convection phenomenon to improve the thermal efficiency by heating the room temperature for a long time by the latent heat even in the time when the boiler is not operating with uniform temperature rise.

Here, the pipe panel 80 is inserted into the heat conduction plate 90 and the heating pipe 70 together in the pipe fixing groove 85 to maintain a solid and stable coupling state while the thickness is 30mm to reduce the floor impact sound It is preferable to use what is.

The heat conduction plate 90 surrounds the heating pipe 70 and is coupled to the piping panel 80. As shown in FIG. 4, the heating pipe 70 is disposed on the pipe fixing groove 85 of the piping panel 80. In the state of fitting the pipe cover grooves (95) surrounding the heating pipe 70 is formed in a plurality of spaced apart at regular intervals, the pipe cover groove (95) while the heating pipe 70 wrapped around the pipe fixing groove ( 85, the heating pipe (70) to prevent the portion of the plane 96 covering the upper surface of the pipe panel 80 is pressed upwards or unevenly deformed while the edges of the openings of the pipe cover groove (95) is pressed in the process of fitting to the pipe cover groove (95). ) Is formed in the shape of the letter 'U', and the inclined surface 97 is formed between the edge of the opening and the plane 96 covering the upper surface of the piping panel 80. It is.

That is, since the inclined surface 97 of the heat conduction plate 90 minimizes the contact interference when the heating pipe 70 is inserted into the pipe cover groove 95 due to its shape, the plane 96 is lifted upward. It can be prevented and insertion and mounting can be made easily and easily.

The thermal conductive plate 90 is 60 to 65% by weight of SEBS (styrene-ethylene / butylene-styrene), 6 to 6.5% by weight of flame retardant, 16 to 17% by weight of paraffin-based processing oil, and 2 to 2.5 weight of lubricant %, Stabilizer 2 to 2.5% by weight, hard coal 6 to 6.5% by weight and carbon black 2 to 5% by weight, and then molded by injection or extrusion method, the thickness of the pipe cover groove 95 portion is 1mm and flat The thickness of the part 96 and the inclined surface 97 can be 1.5 mm.

Here, SEBS has no cracking phenomenon due to ozone, and has excellent elongation and tensile tear strength, so it maintains physical properties stably even when used for a long time, has excellent processability such as injection and extrusion, and the material itself has elasticity. It is preferable to use the thing of 2.0-3.0 micrometers. If the particle size is larger than 3.0 mu m, material separation phenomenon is caused due to the difficulty of uniform mixing, which makes it difficult to obtain a high quality thermal conductive plate.

In addition, when the content of SEBS is less than 60% by weight relative to the composition of the entire heat conduction plate 90, the thermal conductivity is excellent, but toughness and rigidity may be lowered. Can be.

In addition, the carbon black not only increases mechanical properties such as hardness and tensile strength of the heat conductive plate 90, but also provides electrical conductivity to exhibit excellent thermal conductivity. The average particle size is 0.8 μm or less and the surface area and oil absorption ability are excellent. It is preferable to use.

In this case, the carbon black may contain 2 to 5% by weight relative to 100% by weight of the total composition of the heat conductive plate 90, and thus, desirable effects such as improvement of moldability, thermal stability, and mechanical properties of the heat conductive plate 90 may be exhibited. That is, the higher the carbon black ratio, the better the thermal conductivity, but the workability and flowability of the product may be significantly reduced.

On the other hand, the flame retardant, paraffin-based processing oil, lubricants, stabilizers, hard coal, etc. in the composition constituting the thermal conductive plate 90 is a component having the same effect and function as the composition of the above-described dustproof port 30, so the detailed description thereof will be omitted. do.

However, the average particle size of the flame retardant is 2.0 μm or less, preferably 6 to 6.5% by weight relative to the composition content of the entire thermal conductive plate 90.

If the content of the paraffin-based processing oil is less than 16% by weight, proper moldability may not be imparted.If the content of paraffin-based processing oil is more than 17% by weight, the binding force between the materials may be deteriorated, so that the sound absorption performance may be degraded, and transition may occur to cause contamination. have.

And when the content of the lubricant is less than 2% by weight relative to the total content of the composition of the heat conduction plate 90, the performance may not be properly exhibited. If the content of the lubricant exceeds 2.5% by weight, the bonding force between the materials may be deteriorated and the sound absorption performance may be deteriorated.

And the content of the stabilizer is preferably used 2 to 2.5% by weight relative to the composition content of the entire heat conducting plate (90).

And when the content of hard coal is less than 6% by weight relative to the total content of the heat conduction plate 90, desorption occurs or breakage of pores does not provide sufficient strength, and when it exceeds 6.5% by weight, molding to an appropriate shape is performed. Not only is it poorly made, but the strength of the finished product is too strong to cause the disadvantages of breaking easily, and the use of the part is marvelous on the surface, as well as the sound insulation or sound insulation may be degraded.

The heat conduction plate 90 has an excellent sound conduction and sound absorption function as well as a heat conduction function to conduct the heat of the heating pipe 70 evenly, and minimizes the propagation of noise due to the impact applied to the floor to an adjacent generation.

Meanwhile, as shown in FIG. 5, the plurality of heat conducting plates 290 ′ may be seated and coupled on one pipe panel 280 with only one pipe cover groove 295 surrounding the heating pipe 270 being formed. .

The ocher board 100 is laid on the top surface of the heat conduction plate 90 and laid on top of it, and the sound insulation is excellent, and the thickness thereof is preferably 12 mm.

Here, even if used by replacing the Mg board in place of the ocher board 100 can be expected the same sound insulation performance.

On the other hand, the bottom slab (S) and the wall (W) by attaching a separate side buffer 110 along the edge wall surface of the bottom slab (S) in contact with each other can block the transmission of the impact sound and vibration to the side.

That is, when an impact force is generated on the surface of the bottom layer, the wavelength of the solid transmission sound is blocked without being transmitted to the wall W due to the gap between the bottom layer and the wall W and the buffer 110. However, it can be distributed and propagated to the bottom slab (S) below, but it is absorbed and buffered by the sound absorbing mat 20 and the anti-vibration port 30, and the sound pressure generated by resonance and resonance phenomenon leaks into the gap energy. As a result, sound pressure can be prevented and attenuated as a result, thereby minimizing the transmission of floor impact sounds.

As the side buffer 110, it is preferable to use a polyester-based foamed resin having a thickness of 10mm or more.

Such ondol floor according to the first embodiment of the present invention can be constructed in the following order and method.

First, the side cushioning material 110 is attached along the edge wall surface of the bottom slab S, and then the polyethylene foam 10 is laid on the bottom surface of the bottom slab S so as to be in close contact. At this time, in order to maintain the flatness of the floor and to prevent the penetration of moisture, one polyethylene foam and another adjacent polyethylene foam are attached with adhesive tape or the like to be connected to each other without a gap.

Thereafter, the sound absorbing mat 20 is placed on the polyethylene foam 10 in close contact with each other so that a gap does not occur between the side cushioning material 110 on the wall surface, and a flooring layer on the sound absorbing mat 20 with a tool such as a drill. In consideration of the stability of the structure according to the installation in a predetermined interval and a predetermined pattern, preferably drilled a plurality of dustproof holes 25 at intervals of 600mm × 300mm, and then the dustproof holes 30 are formed in the dustproof holes 25. Insert and install each so as not to be spaced apart from the bottom slab (S).

Here, the dustproof holes 25 of the sound absorbing mat 20 may be installed after perforation in a separate place in consideration of the working conditions or environment of the installation place, of course.

Subsequently, the Mg board 40, the cushioning sheet 50, and the insulating sheet 60 are sequentially laid on the sound absorbing mat 20 and the dustproof opening 30 so as to be horizontally stacked, and then stacked on the insulating sheet 60. The piping panel 80 is mounted in the same direction as another adjacent piping panel, and the pipe cover groove 95 portion of the heat conduction plate 90 is fitted into the pipe fixing groove 85 of the piping panel 80. After placing the heat conduction plate 90 on the pipe panel 80 to form a heating pipe 70 is inserted into the pipe cover groove (95) of the heat conduction plate 90 and coupled.

At this time, in order to maintain the flatness of the floor and to prevent the penetration of moisture, the insulating sheet 60 is in close contact with the buffer sheet 50 so as not to generate a gap, and then the joint portion with another adjacent insulating sheet is an adhesive tape or the like. Attached to each other without a gap, the pipe panel 80 is installed so as to be in close contact with the bottom surface, so that the laminar phenomenon may occur when a gap occurs with the insulating sheet 60, the heating pipe 70 is a pipe panel ( It is completely buried so that it is not exposed to the upper part of 80).

In this process, the shape of the pipe cover groove 95 surrounding the heating pipe 70 of the pipe panel 80 is formed in the shape of an alphabet 'U', and the edges of both ends of the opening and the top surface of the pipe panel 80 are formed. Since the inclined surfaces are formed between the covering surfaces 96, the edges of the openings of the grooves surrounding the heating pipes 70 are pressed as before, and the flat portions covering the upper surfaces of the piping panels 80 are lifted upwards or bumpy. The deformation can be prevented.

Thereafter, the ocher board 100 is laid on the heat conduction plate 90 and then laid on top of it, and then the floor finishing material such as floorboard or deco tile, reinforced floor is laid and finished, thereby significantly reducing the noise between floors of the apartment house. A dry ondol floor can be completed.
