Description

Vibration adaptive vibration control device for reducing inter-floor noise and its method {ADAPTIVE VIBRATION CONTROL APPARATUS FOR REDUCING NOISE BETWEEN FLOORS, AND METHOD FOR THE SAME}

The present invention relates to a vibration-adaptive vibration control device, and more specifically, to actively adapt and control the vibration according to the magnitude of vibration transmitted through the floor slab so as to reduce the inter-floor noise generated in the upper floor of an apartment house, etc. It relates to a vibration-adaptive vibration control device for reduction and a method thereof.

Currently, in Korea, many apartment houses represented by apartments are built, and the inconvenience caused by inter-floor noise and vibration of such apartment houses is pointed out as a unique inconvenience only for apartment houses. In particular, in the case of an apartment house where the wall and floor must be shared with neighboring households, the floor impact sound applied to the floor due to walking indoors, jumping of children, falling objects, and moving other furniture is transmitted to the lower floor. The noise and vibration between floors are causing unpleasant things among neighbors who want to rest in a pleasant and quiet environment.

Accordingly, the government revised the "Regulations on Housing Construction Standards," and newly reorganized the floor impact sound standards to reduce the noise between floors of apartment houses, especially apartments. According to these regulations, the standard of floor impact sound between floors of an apartment house is divided into a light-weight impact sound that a small object falls, and a weight impact sound that a child runs, and applies it to new apartment houses in the future. The floor impact sound standard refers to a level at which the sound of dragging a table chair is not heard on the lower floor, and the sound of a child running around does not cause discomfort.

As a structural vibration control device for reducing such inter-floor noise, it is composed of a support fixed to a floor plate, a damping plate fixed to and spaced apart from the support, and a magnetorheological damper (with a pressurizing piston). This is a device for canceling the vibration of the floor plate and the damping plate through a magnetic rheological damper in which the damping plate spaced apart from the floor plate vibrates when the floor plate vibrates through the support.

Specifically, Korean Patent Application Publication No. 2010-2810 discloses an invention entitled "Vibration control device for a floor plate structure using a magnetic rheological damper and a damping plate", which will be described with reference to FIGS. 1A and 1B.

Specifically, when the bottom plate 10 vibrates due to impact in the upper layer, the damping plate 23 disposed parallel to the bottom plate 10 via the first and second supports 21 and 22 also vibrates, The magnetoresistive damper 24 cancels the vibration of the bottom plate 10 and the vibration of the damping plate 23 while fluidly connecting the bottom plate 10 and the damping plate 23. At this time, the bottom plate 10 exhibits a vibration shape canceled from the vibration shape of the damping plate 23 itself, and the vibration is stabilized. Here, the magnetorheological attenuator 24 is a magnetorheological fluid injected into the cylinder 24a of a general damper, as shown in FIG. 1B, and the magnetorheological fluid has a property of increasing viscosity in a magnetic field. It is a material to have.

The vibration control device 20 according to the prior art uses a magnetorheological fluid instead of a general fluid having the same fluidity to adjust the cushioning function of the magnetorheological attenuator 24, so that the supports 21 and 22 and the damping of the same standard are used. Even with the plate 23, it is possible to achieve appropriate vibration control suitable for the characteristics of the bottom plate 10.

In addition, as shown in FIG. 1B, the magnetorheological attenuators 24 are compartmentalized with each other, but communicated through a narrow passage 24c-1, and the first and second chambers 24a are filled with the magnetorheological fluid 24d. -1, 24a-2) cylinder (24a); The first and second fastening means 24b-1 and 24c-1 are inserted into the first and second chambers 24a-1 and 24a-2, respectively, and the ends of the bottom plate 10 and the damping plate 23 are respectively It consists of first and second pressure pistons (24b, 24c) fixed through the medium.

The vibration control device 20 according to the prior art further includes a control module 25 for controlling the magnetorheological damper 24, wherein the control module 25 is a magnetorheological fluid filled in the cylinder 24a. A control means (25a) which applies a magnetic field to (24d) to adjust the damping force possessed by the magnetorheological attenuator (24), and forms a magnetic field directly in the magnetorheological fluid (24d); And an input means 25b for controlling the processing state and operation of the control means 25a, and outputs the state of the magnetorheological fluid 24d or a value input by an administrator manipulating the input means 25b as needed. It may further include an output means (25c).

Specifically, the control means (25a) is electrically connected to the cylinder (24a) via a coil, etc., which is advantageous in forming a magnetic field, and of a sensor that detects the vibration state of the bottom plate 10 and the vibration state of the damping plate 23. A signal is received, the degree of viscosity change of the magnetorheological fluid 24d is calculated, and a magnetic field is created in the cylinder 24a by flowing a current of an appropriate size to the coil to adjust the viscosity of the magnetorheological fluid 24d. Here, the sensor continuously senses the vibration state of the floor plate 10 and transmits it to the control means 25a. For example, the data detected by the sensor is the vibration period and the vibration response (acceleration, speed, Displacement), etc.

According to the vibration control device according to the prior art, it is possible to reduce the burden on the entire building by attenuating the vibration of the floor plate due to the impact within a short time. In addition, while mass-producing in a uniform shape and standard, it is flexibly applied to various locations and Can be installed.

However, in the case of a vibration control device according to the prior art, it can be applied to reduce the floor impact sound of an apartment house, but it must be installed before building construction, so it can be applied to a new house, but there is a limitation that it is difficult to apply it to an existing house.

[Vibration-adaptive vibration control device 100 for reducing inter-floor noise]

4 is a diagram showing a vibration adaptive vibration control device for reducing inter-floor noise according to an embodiment of the present invention, and FIG. 5 is a configuration diagram of a vibration adaptive vibration control device for reducing inter-floor noise according to an embodiment of the present invention to be.

4 and 5, the vibration adaptive vibration control device 100 for reducing inter-floor noise according to an embodiment of the present invention includes vibration generated in the upper floor of an apartment house and transmitted through the floor slab 210. As a vibration control device for reducing noise, it is configured to include a vibration detection sensor 110, a vibration adaptation control unit 120, a hydraulic jack 130, and a vibration isolating pad 140, and reduces inter-floor noise according to an embodiment of the present invention. The vibration adaptive vibration control device 100 for the may be built into the lower floor lamp 240 to reduce vibration transmission, and the lower floor resident who wants to reduce the vibration transmission of the upper floor of the apartment can be easily and conveniently installed. Here, reference numeral 230 denotes a ceiling channel.

The vibration detection sensor 110 is installed under the floor slab 210 of the upper layer to detect vibration or noise transmitted through the floor slab 210 to generate a vibration signal.

The vibration adaptation control unit 120 determines a vibration level according to the vibration signal sensed by the vibration detection sensor 110 and generates a hydraulic drive signal for variably driving the hydraulic jack 130 in response to the determined vibration level.

The hydraulic jack 130 is installed between the floor slab 210 and the ceiling finishing material 220 of the upper layer, and rises or falls according to the hydraulic drive signal generated by the vibration adaptation control unit 120. That is, the hydraulic jack 130 is variably driven in response to the magnitude of vibration transmitted through the floor slab 210 of the upper layer to reduce inter-floor noise. Thereafter, the vibration adaptation control unit 120 drives the hydraulic jack 130 to descend when the vibration is absorbed and reduced by raising the hydraulic jack 130.

The anti-vibration pad 140 is installed under the floor slab 210 and is in close contact with the floor slab 210 of the upper layer as the hydraulic jack 130 rises to reduce vibration.

At this time, the vibration detection sensor 110, the vibration adaptation control unit 120, the hydraulic jack 130, and the anti-vibration pad 140 are between the lower floor ceiling finisher 220 formed on the lower floor lamp 240 and the upper floor slab 210 However, it can be installed directly after the construction of the apartment is completed by the occupants or users of the lower floors affected by the inter-floor noise.

In addition, the vibration detection sensor 110, the vibration adaptation control unit 120, the hydraulic jack 130, and the anti-vibration pad 140 are integrally formed so as to be embedded in the lower layer lamp 240, and the lower layer lamp 240 is replaced. It can be installed easily.

The vibration adaptive vibration control device 100 for reducing inter-floor noise according to an embodiment of the present invention includes a hydraulic jack 130 for controlling the floor slab 210, a vibration detection sensor 110 for monitoring the floor slab vibration, and the floor It is composed of a vibration-proof pad 140 in contact with the slab 210, and when the vibration of the floor slab 210 is monitored by the vibration detection sensor 110, the hydraulic jack 130 is in close contact with the upper part of the vibration-proof pad 140. The vibration is suppressed by being in close contact with the floor slab 210.

In the case of the vibration-adaptive vibration control device 100 for reducing inter-floor noise according to an embodiment of the present invention, first, when a vibration detection sensor 110 monitors the upper floor vibration and detects a certain level of vibration, the hydraulic jack 130 ), in particular, by pushing the piston rod upward and the vibration-proof pad 140 in close contact with the floor slab 210 of the upper layer, vibration generated in the upper layer transmitted through the ceiling can be actively suppressed.

On the other hand, Figure 6 is a configuration diagram showing in detail a vibration adaptation control unit in the vibration-adaptive vibration control device for reducing inter-floor noise according to an embodiment of the present invention.

6, in the vibration adaptive vibration control device for reducing inter-floor noise according to an embodiment of the present invention, the vibration adaptation control unit 120 includes a data conversion unit 121, a reference value setting unit 122, and a vibration level determination. The unit 123, the hydraulic drive signal generating unit 124, the hydraulic jack driving unit 125, and the power supply unit 126 may be included, but the present invention is not limited thereto.

The data conversion unit 121 converts the analog vibration signal generated by the vibration detection sensor 110 into a digital vibration signal. That is, since the signal sensed by the vibration detection sensor 110 and generated is an analog vibration signal, the data conversion unit 121 amplifies the analog vibration signal and converts it into a digital vibration signal.

The reference value setting unit 122 sets a reference value corresponding to the vibration signal transmitted through the floor slab 210. In this case, the reference value set by the reference value setting unit 122 may be determined in advance through an experiment. That is, the reference value setting unit 122 sets a reference value to check whether the vibration signal generated by the vibration detection sensor 110 is equal to or higher than a predetermined level.

The vibration level determining unit 123 compares the digital vibration signal with a reference value preset by the reference value setting unit 122 to determine the vibration level of the vibration signal.

The hydraulic drive signal generation unit 124 generates a hydraulic drive signal corresponding to the vibration level of the vibration signal determined by the vibration level determination unit 123. At this time, when the vibration magnitude of the vibration signal is very small, the hydraulic drive signal may not be generated, but the vibration adaptive vibration control device 100 for reducing inter-floor noise according to an embodiment of the present invention actively controls the vibration. In order to do this, it is desirable to generate a hydraulic drive signal corresponding to the magnitude of the vibration for all vibration signals. Accordingly, when the vibration signal is generated from the upper layer, the hydraulic jack 130 can be controlled to rise or fall according to the hydraulic drive signal.

The hydraulic jack driving unit 125 variably drives the hydraulic jack 130 according to the hydraulic driving signal generated by the hydraulic driving signal generating unit 124. That is, it is possible to variably drive the hydraulic jack 130 in response to the magnitude of the vibration.

The power supply unit 126 supplies required power to the data conversion unit 121, the reference value setting unit 122, the vibration level determining unit 123, the hydraulic drive signal generation unit 124, and the hydraulic jack driving unit 125. For example, the power supply unit 126 converts the AC commercial power supply 250 to DC, and then generates the data conversion unit 121, the reference value setting unit 122, the vibration level determining unit 123, and a hydraulic drive signal.
