Description

Dry heating panel for reducing floor noise {Dry heating panel for buffing noises between stairs}

The present invention relates to a structure of a dry heating panel for reducing noise between floors, and more particularly, to a structure of a dry heating panel for reducing noise between floors having an excellent heating efficiency and improving floor impact noise reduction performance.

In general, building structures for heating not only a living room or a bedroom but also a bathroom are increasing for a comfortable indoor life of the occupants, and a heating structure is installed on the floor of the bathroom to heat the bathroom.

The floor heating of the bathroom is a method of arranging a heating coil for supplying hot water on the floor slab, then covering the heating coil with a mortar to form a mortar layer, and finishing with a floor finish such as tiles on the upper surface of the mortar layer. Although it is used, such construction methods require expertise in prolonging the construction period and the accuracy of the gradient of the heating coil, and have a problem that it takes a lot of time and cost due to the dismantling of the mortar layer when the heating coil leaks.

In order to solve this problem, a prefabricated heating panel has been developed and constructed, which will be described below with reference to the accompanying drawings.

1 is an exploded perspective view illustrating a prefabricated heating panel used in a floor heating construction method according to a conventional example, which is a "prefabricated heating panel and its installation method" of No. 472088 registered with the Korean Intellectual Property Office. As shown in FIG. 1, the floor heating construction method according to a conventional example includes installing a support plate 15 having a groove 17 formed on an upper surface of a slab in order to reduce heat loss and interlayer noise; Inserting and installing a heat transfer metal plate 19 having a shape in the recess 17, inserting and installing a heat medium circulation pipe 21 into a groove of the heat transfer metal plate 19, and It is composed of a step of loading the upper panel 27 for the heating panel formed of the inorganic heat storage material laminated on the upper surface of the base material layer of the compressed fiber material having a soundproofing and cushioning on the top. Here, the upper plate 27 is manufactured by adhering and laminating a heat storage material 25 such as an inorganic filler on the upper side of the base material 23 having a soundproofing and cushioning material such as a compressed fiber material.

In addition, Figure 2 is an exploded perspective view showing a prefabricated heating panel used in the floor heating construction method according to another conventional example, the "heat panel structure" of Utility Model Registration No. 362619 registered with the Korean Intellectual Property Office. As shown in FIG. 2, the heat panel 30 used in the floor heating construction method according to another example of the related art has a moisture proof paper 32 laminated on an upper side of a bottom surface 31 made of concrete and wood, and a moisture proof paper Insulation material 35 is formed with a pipe groove 34 into which the hot water pipe 33 is inserted, and the hot water pipe 33 which is seated on the heat insulating material 35 and is wound with aluminum tape to improve thermal conductivity. , A heat sink 36 for dissipating heat from the upper layer of the hot water pipe 33, and a finish 37 seated on the heat sink 36 to treat the surface. Here, a sound insulation material 38 for reducing vibration and noise is provided between the bottom surface 31 and the moisture proof paper 32, and the bioceramic layer 39 is interposed between the heat sink 36 and the finish material 37.

However, such conventional prefabricated heating panels do not provide a countermeasure against floor impact noise. In other words, conventional prefabricated heating panels are effective and economical countermeasures for reducing floor impact noise by increasing the floor slab thickness and installing a cushioning material between the slab and the ondol constituent layer, or by staying at an alternative level of material for reducing the floor impact sound. There is a limit to provision.

Early floor impact researchers found that the floor impact sound was simply caused by the insulation between the slab and the lightweight foam concrete. Therefore, the concept of dynamic modulus of elasticity was introduced and flexible insulating buffers were developed. This product had a significant effect on lightweight impact sounds, but it was difficult to understand that it did not reduce or rather amplify weight impact sounds, which is the main cause of actual complaints. Since then, many researches and developments have been carried out with national support, but even now, we have not been able to produce satisfactory results and products.

In order to solve the conventional problems as described above, the present invention is to develop a dry heating panel structure for reducing the noise between floors to bring improved floor impact sound reduction performance.

At present, Korea has presented low-carbon green growth as a national vision for the future, is speeding up the enactment and revision of relevant laws, and spares no political, technical and economic support. Although prefabricated heating panels can make a significant contribution to energy savings at this point, there are limitations in solving problems related to floor impact sound. Therefore, for this reason, the improvement of the floor impact sound performance problem has become an important issue, and accordingly, the present invention intends to achieve the improvement of the floor impact sound reduction performance due to the dry floor heating structure for reducing the noise between floors.

The structure 100 of the dry heating panel for reducing noise between floors according to the present invention can have a significant contribution to energy saving and improve floor impact sound reduction performance by having excellent heating efficiency.

There are several methods to be used as an equation for predicting the existing floor impact sound. However, when the impact sound is a heavy shock sound, a prediction equation using an impedance method is mainly used as in Equation 1 below.

Where F _rms is the effective force of impact force (N) of the heavy impact source, L _{Z .T} is the correction of the slab peripheral restraint to the basic impedance value of the slab, impedance reduction considering the influence of resonance (dB), and S _eff is the slab Is the effective radiation area (m 2), k is the acoustic radiation coefficient, A is the sound absorption power (m 2) of the sound receiving room, and ΔC is the dynamic characteristic correction value (dB) of the sound level meter.

When the impact sound is a lightweight impact sound, Equation 2 below is mainly used.

Where LL is the octave band average floor impact sound level (dB) by the light impact source, F _rms is the impact force effective value (N) when impacting the concrete exposed surface by the light impact source, and Zb is the basic impedance value of the concrete floor slab (kg / s), T60 is the 60 dB attenuation time (s) for concrete floor slabs, k _rad is the acoustic radiation coefficient of the concrete floor slab, h is the thickness of the concrete floor slab (m), and A is the sound absorption capacity of the sound receiving chamber (㎡), 173.5 Is the constant (dB) for concrete floor slab, and ΔL is the improvement of floor impact sound (dB) by surface finish.

These impedance equations are difficult to apply to domestic wall structures. For this reason, the structures for applying the prediction equations are based on a laboratory fixed with four sides of a column. The performance deviation is severe. Rather than using these prediction principles, the use of finite element analysis programs and floor shocks are reported as vibrations and are being tried.

As mentioned above, the floor impact sound has many variables and factors that affect the performance of the floor impact sound. In spite of these problems, the direction to reduce the floor shock sound is presented in the first, “Development of the floor shock sound blocking structure of the common house”, and secondly, the method of reinforcing the stiffness of the slab, and finally using the vibration damping material. There may be a method, etc., the structure 100 of the dry heating panel for reducing the noise between the floors according to the present invention has been proved that the amount of reduction in the laboratory is sufficient to obtain the first floor certified floor structure.
