The present invention relates to a movable screen-type soundproof wall, more specifically, to move to a place where noise occurs, easy to install and dismantle, it is made of a configuration to be folded in the form of a screen can be easily installed without being limited by the installation place. The present invention relates to a mobile folding soundproof wall configured to be easily coupled to a plurality of soundproof walls.

The present invention allows the soundproof panel to be folded in a configuration of a folding screen, to form a handle portion and a wheel to facilitate transportation around the place and machinery where noise is generated, and to be easily installed, dismantled and stored, and a folding screen. Due to the folding configuration, there is no restriction on the place of installation, so the space utilization is excellent, and sound-absorbing materials and sound-absorbing materials used for soundproof panels are made of foamed aluminum foam and melanin resin foam to prevent harmful dust and gas. Insulation effect is excellent, so it can be used as a firewall, can be used in the form of a partition in the place where a disaster can occur, and a handle folding means is formed on the handle part so that multiple screen-type soundproof walls can be connected while the handle part is folded. It has the effect of improving the utility of the product.

Recently, the desire to live in a pleasant and quiet environment has been increasing due to the improvement of living standards, but various construction works are increasing according to the industrial and economic development, and the noise and vibration sources such as small factories, workplaces, loudspeakers, etc. are around the residential area. This is scattered and the damage caused by noise is a serious situation.

In order to prevent damage caused by such noise, the government has set noise and vibration regulation standards to regulate noise and maintain a quiet and pleasant living environment.In particular, in the case of construction noise regulation standards, public holidays are strengthened rather than weekdays. It is mandatory to install the soundproof wall before the start of construction for the specific construction. Since January 1, 2006, the standard for installing the soundproof wall is to provide the sound insulation effect of at least 7dB and height of 3m or more to protect residents from the pollution of noise. Various policies are presented.

In general, the soundproof walls are operated by various mechanical equipments of industrial sites, which are places where noise is generated a lot. It is installed to block the noise from the place where the means of transportation such as railroad, subway, aircraft, etc. or various construction using heavy equipment to spread to the outside.

As mentioned above, H-beam pillars are usually installed around steel plants, railway lines, airports, construction sites, and roads with lots of traffic, so that materials such as wool or polyester resin are coated on the galvanized steel. There is a reflective type that reflects the noise to the place where it is used to sound and propagates to the outside, and is used for soundproofing inside such as music halls, theaters, performance halls, indoor sports venues, offices and broadcasting stations that use a lot of audio equipment. Is a fixed soundproof wall that is soundproofed by attaching various materials such as synthetic resin mixed with polyethylene, polyester, etc., or inorganic fiber such as rock wool, and metal materials as single or composite materials to PVC resin with sound absorption or sound insulation effect. It is used.

In the case of the conventional soundproof wall facility, the construction is enormous and requires a lot of construction cost, and the work process for installing the soundproof wall is difficult, requiring a lot of manpower and materials, and a lot of manpower and work time is required even when dismantling. In particular, devices that generate noise while moving at a certain place, such as compressors, concrete cutter systems, and hammer drills, which are frequently used in construction sites, do not prevent noise from propagating. Not protected, there is a problem that is exposed as it is damaged by noise.

The present invention has been made in order to solve the above-mentioned conventional problems, it is easy to move around the place where the noise is generated and the mechanical device, easy to install and remove the soundproof wall, the soundproof panel is folded in the form of folding screen It is possible to install without being restricted by the installation place, so the use of space is excellent, and the purpose is to improve the utility of the product by easily connecting and combining a plurality of soundproof walls.

In the construction of the soundproof wall to achieve the above object, the sound absorbing material, the soundproofing material, and the cover part are sequentially stacked to form a soundproof panel to be fixedly coupled by a square frame, and the soundproof panel is divided into upper and lower sides by an angle adjusting means. The upper soundproof panel is configured to be adjusted at a constant angle, and the panel hinges are connected to one side and the other side of the soundproof panel so as to cross each other, and the plurality of soundproof panels are folded in the form of a screen, and the soundproof walls are formed on both sides of the soundproof wall. Handles are formed on the panel symmetrically, the handle portion is made of a folding configuration to the soundproof panel by the handle folding means, forming a coupling portion formed with a coupling hole in the lower end of the soundproof panel to be fixedly coupled by a coupling pin between the soundproof walls The wheel is formed on the lower side of the soundproof panel I will have to implement a folding-type portable sound barriers are.

Hereinafter, with reference to the drawings will be described in detail with respect to the movable screen-type soundproof wall applied to the present invention.
