Description

Movable Noise Barrier

The present invention relates to a portable soundproof wall, and more particularly, to a lightweight movable soundproof wall capable of preventing dust from being scattered and being folded together with a sound at a construction site or a lane.

Generally, a soundproof wall is a wall that is installed to intercept sound coming from the outside or sound emitted from the room to another place. In other words, all walls installed to block sound are called soundproof walls. This is mainly aimed at blocking the noise, so it is installed between the place where the noise is heard and the place where the noise is heard, and a large sound barrier installed next to the road is representative. Since the sound is transmitted in the form of waves, the sound barrier is made considering the laws of motion of the waves. Therefore, it is common to increase the height or to make the thickness thick. It can also be made using special materials that can absorb sound waves. Soundproofing walls are made considering the sound receiving point which is the place where the noise is most received. Sound absorbing ratio of how much sound can be absorbed during manufacturing, transmission loss of how much noise passed through the wall is reduced, decibel value And insertion loss, which is how much it is reduced. In Korea, soundproof walls are manufactured and installed according to the standards stipulated by the Ministry of Environment, and the aesthetics and safety aspects as well as the functional aspects are considered here.

In addition, the sound is largely absorbed when the surface is rough or when open bubbles come in contact with a material wall having many voids. When sound energy causes resonance in the air gap, the sound energy is converted into thermal energy by the friction between the air particles and the material. The material made by using the reduction of sound energy is called sound absorbing material. Generally used sound absorbing materials absorb more than 70% of sound energy. As a result, a part of the sound that touches the surface of the soundproof wall is absorbed by the sound absorbing material, and the rest is reflected or passed through the soundproof wall and continues. Therefore, in addition to the use of sound absorbing materials to reduce noise, it is also possible to prevent the diffraction phenomenon in which sound is transmitted behind obstacles simply by increasing physical height or thickness. This is called diffraction damping effect.

Conventionally, a soundproof wall installed on a construction site, a lane or the like is usually manufactured in a large size. However, due to the nature of the terminal site, installing or demolishing a sound barrier in order to prevent noise or vibration from occurring in frequent moving places has been time and costly.

In addition, there is a conventional method in which air can be injected into or withdrawn from a soundproof wall-shaped tube for easy installation and demolition of the soundproof wall. However, the volume and weight of the soundproof wall tube are large and the air injected into the tube is inadvertently discharged, And it takes much time to inject or withdraw air from the tube, which is not suitable for transportation.

In Fig. 2, a pair of vertical assemblies 10, 20 is provided, in which a plurality of unit frames 11-13, 21-23 are longitudinally coupled to the stationary frame 2. [ The vertical assemblies 10, 20 are positioned at regular intervals. Each of the vertical assemblies 10 and 20 is combined with a plurality of unit frames 11-13 and 21-23 to determine the height of the vertical assemblies 10 and 20. That is, the height of the vertical assemblies 10 and 20 is determined according to the lengths and the number of the unit frames 11-13 and 21-23. The unit frames 11-13 and 21-23 are formed in the shape of a pipe so that the fitting portions and the inserting portions are formed so that they can be inserted and joined.

The lower assembling members 15 and 25 are respectively coupled to the lower ends of the vertical assemblies 10 and 20. The lower assembling members 15 and 25 have a shape in which a pipe projecting inward from the stationary frame 2 is coupled in a pipe shape.

The upper assembling members 16 and 26 are respectively coupled to the upper ends of the vertical assemblies 10 and 20. The upper assembling members 16 and 26 are formed at three angles in a pipe shape. That is, the upper ends of the upper assembling members 16 and 26 are bent at a predetermined angle so that the inclining angle frame 30 is engaged, the lower ends of the upper assembling members 16 and 26 are engaged with the unit frames 11 and 21, 16, and 26, respectively.

The inclined angle frame 30 is coupled to the upper ends of the upper assembling members 16 and 26 at respective angles, respectively. The inclined angle frame 30 is folded at a predetermined angle from the vertical assemblies 10 and 20 in a substantially 'C' shape.

The first horizontal frame 31 is laterally coupled between the upper assembling members 16, 26. The first horizontal frame 31 is formed in a pipe-like shape so as to be able to engage with and engage with the pipe. The second horizontal frame 32 is laterally coupled between the lower assembling members 15, 25. The second horizontal frame (32) has a shape such as a pipe, and a fitting portion is formed so as to be able to engage with each other.

Thus, the fixing frame 2 includes the inclined angle frame 30, the upper assembling members 16 and 26, the first horizontal frame 31, the vertical assemblies 10 and 20, the lower assembling members 16 and 26, The frame 32 has a structure that is fitted or separated by fitting.

The support block 40 has a block shape in which a plurality of fixing holes 41 are formed in an upper portion thereof and the lower assembling members 15 and 25 are respectively inserted and fixed to the fixing holes 41. The support block 40 may be made of a metal, a stone, or a concrete material having a predetermined weight, but it may be a bucket made of a synthetic resin which can be filled with water to exhibit a certain weight. The movable block may be easily moved by adopting a roller at the lower end of the support block 40.

3, the soundproofing material 3 has a plurality of first fixing members 51 mounted on the front surface thereof and a plurality of second fixing members 52 mounted on the rear surface thereof. And can be fixedly coupled to the vertical assemblies 10 and 20 of the fixing frame 2 and the first horizontal frame 31 and the second horizontal frame 32 with the first fixing member 51, respectively. The first fixing member 51 and the second fixing member 52 may be provided with a string or a Velcro tape. The sound insulating material 3 may be a cloth, a sponge, a synthetic resin, or the like capable of blocking noise or vibration.

The sound absorbing material 4 is formed with an embossing 55 on its front face and a third fixing member 53 on its back face. And the third fixing member 53 can be fixedly coupled to the second fixing member 52 of the soundproofing material 3. [ The third fixing member 53 may be a string or a Velcro tape. The embossing 55 formed on the front surface of the sound-absorbing material 4 may be structured such that irregularities such as an egg plate are formed and noise or vibration incident thereon can be extinguished. The sound absorbing material 4 may be formed of a material having many pores, and sponge, cotton or synthetic resin fiber may be applied.

The movable sound barrier 1 of the present invention provides ease of assembly. A plurality of unit frames 11-13 and 21-23 having a fitting portion and an insertion portion are connected and connected to each other to form a vertical assembly 10 and 20, The upper assembly members 16 and 26 are connected and coupled to the lower assembly members 15 and 25 at the lower ends of the vertical assemblies 10 and 20, respectively. The first horizontal frame 31 is coupled to the upper assembling members 16 and 26 in the transverse direction together with the connection of the inclined angle frame 30. Further, the second horizontal frame 32 is coupled to the lower assembling members 15, 25 in the transverse direction. A portion extending to the lower end of the lower assembling members 15 and 25 is inserted and fixed in the fixing hole 41 of the support block 40. [

When the assembly of the fixing frame 2 is completed, the first fixing member 51 of the soundproofing material 3 is used to engage the front surface of the fixing frame 2 with each other. At this time, the soundproofing material 3 is fixedly coupled over the entire surface of the stationary frame 2. The first fixing member 51 fixes the sound insulating material 3 to the fixing frame 2 by a combination of a string that can be bound or a button coupled to a string or a male and female coupling of a Velcro tape.

In addition, the sound absorbing material 4 is fixedly coupled over the entire surface of the sound insulating material 3 fixedly coupled to the stationary frame 2. The second fixing member 52 of the soundproofing material 3 and the third fixing member 53 of the sound absorbing material 4 are fixed to each other. The second fixing member 52 and the third fixing member 53 may be fixed to each other by a combination of a button or a button coupled to a string or a string or may be fixed to the second fixing member 52 or the third fixing member 53, When tape is applied, it is bonded by mutual adhesion.

Thus, the soundproofing material 3 is coupled to the fixing frame 2, and the sound absorbing material 4 is coupled to the soundproofing material 3, thereby completing the assembly of the movable soundproofing wall.

7, the ends of the lower assembling members 15 and 25 assembled to the stationary frame 2 of the movable soundproof wall 1 are inserted into any one of the fixing holes 41 formed in one support block 40, The end portions of the lower assembling members 15 and 25 assembled to the stationary frame 2 of the other movable soundproof wall are inserted and fixed to another stationary hole 41 formed in the support block 40, (1) can be continuously installed. Therefore, the movable sound barrier walls can be connected to one or the left and the right continuously, so that a sound barrier wall having a desired length can be formed. Therefore, it can be partially installed depending on the size and range of noise and vibration generated from the construction site or the lane of the terminal.

Furthermore, the movable sound barrier is light in weight and can be installed easily while moving, and it is easy to separate for demolishing the movable sound barrier, and it is convenient to carry it on the vehicle because of its small volume and weight after being separated.

4, in another embodiment of the present invention, an elastic body 35 which connects the unit frames to each other is coupled inside the unit frames 11-13 and 21-23 of the vertical assemblies 10 and 20. The elastic body 35 is made of natural rubber, synthetic rubber, synthetic resin having elasticity, or the like. Therefore, the unit frames of the vertical assemblies 10 and 20 are connected together by the inner elastic body 35 even when the coupled parts are separated. That is, in FIG. 5, the unit frames 11-13 and 21-23 of the vertical assemblies 10 and 20 are separated by the elastic body 35 even when they are separated. From this, it is possible to easily reduce the volume and size of the fixing frame 2, in particular, the vertical assemblies 10 and 20 after separation, and prevent the loss of the vertical assembly.
