Description

Soundproof panel assembly with increased acoustic reflection rate by increasing surface density and its construction method

Embodiments of the present disclosure relate to a soundproof panel assembly applicable to a ceiling or interior wall of a building and a method for constructing the same, and more specifically, to a multi-layered soundproof panel assembly for increasing sound reflection rate and improving soundproofing performance by increasing surface density and a method for constructing the same.

The acoustic environment of an indoor space is a very important factor in various places such as performance halls, broadcasting studios, conference rooms, and lecture halls.

In particular, acoustic reflectivity determines the extent to which sound waves generated within a space are reflected and transmitted from walls or ceilings, which has a significant impact on the clarity and reverberation of the sound transmitted to the listener.

Most existing soundproofing panels or sound-absorbing panels are composed mainly of sound-absorbing materials, which can absorb sound and reduce noise, but they have the disadvantage of maintaining a low sound reflection rate.

In particular, in spaces where clear reflection of sound is required, such as music concert halls or broadcast recording studios, excessive sound absorption can actually cause deterioration of sound quality or errors in spatial interpretation.

In addition, most conventional sound-absorbing/soundproofing panel structures are composed of wood fiberboard (MDF), gypsum board, or fiberglass-based sound-absorbing materials, which also have the problem of insufficient eco-friendliness and non-combustibility.

Accordingly, its application was sometimes limited in public facilities or large commercial spaces where fire safety is important.

In addition, conventional panels were specialized for either wall or ceiling use, resulting in poor structural uniformity and requiring separate product designs depending on the installation environment, which resulted in low construction efficiency and increased costs.

Accordingly, there is a need for an integrated soundproofing panel assembly that increases sound reflectivity, is fire-resistant, offers ease of construction and is environmentally friendly, and can be applied to both ceilings and walls.

Here, FIG. 1 is a perspective view of a soundproof panel assembly having increased sound reflectivity by improving surface density according to one embodiment of the present disclosure, FIG. 2 is an exploded perspective view of the soundproof panel assembly of FIG. 1, FIG. 3 is a partial cross-sectional view showing a state in which a soundproof panel assembly having increased sound reflectivity by improving surface density according to one embodiment of the present disclosure is installed on an indoor ceiling of a building, and FIG. 4 is a flowchart of a construction method of a soundproof panel assembly having increased sound reflectivity by improving surface density according to one embodiment of the present disclosure.

The soundproof panel assembly of the present invention, which increases sound reflectivity by improving surface density, as illustrated in FIG. 1 or FIG. 2, largely comprises a plurality of square steel pipes (100) installed on a wall or ceiling of an indoor space, a GRG (Glass Fiber Reinforced Gypsum) fireproof finishing material (110) filled in multiple layers in the space between the square steel pipes, a PE film (130) and a damper sheet (140) attached to the indoor side of the GRG fireproof finishing material and the square steel pipes, and a plurality of eco-friendly fireproof FG boards (150) adhesively fixed to the outer side of the PE film and the damper sheet, so that the surface density can be improved for the same area, thereby increasing sound reflectivity.

The soundproof panel assembly of the present invention can be installed on a wall and/or ceiling inside a building to increase the area density per unit volume, thereby greatly improving sound reflectance.

First, the square steel pipe (100) is a rigid structure made of aluminum or galvanized steel and may be a hollow pipe.

The above square steel pipe (100) may be installed in multiple pieces in a row at an appropriate distance along an indoor wall and/or ceiling with a certain length.

Preferably, a rectangular steel pipe (100) of a rectangular parallelepiped can be fixedly installed on a concrete surface forming an interior with a bottom surface having a smaller area than the side surface.

Referring to Fig. 3, an anchor bolt (102) can be installed on a concrete surface by penetrating the square steel pipe (100).

Here, in order to install the square steel pipe (100) on the concrete surface, it is not limited to an anchor bolt (102), and it may be installed using a separate bracket, etc.

Furthermore, the above square steel pipe (100) may have a size of 100*50mm.

And, insulation material (160) can be filled into the interior of the hollow square steel pipe (100).

The above insulation material (160) is described again below.

Continuing, the above-described GRG (Glass Fiber Reinforced Gypsum) fireproof finishing material (110) can be filled in multiple layers in the space between the square steel pipes (100).

In the above GRG non-combustible finishing material (110), GRG is an abbreviation for ‘Glass Fiber Reinforced Gypsum’, which can be simply put, glass fiber reinforced gypsum.

It is made by adding 'glass fiber' to 'alpha gypsum', a high-strength gypsum as the main ingredient, and this glass fiber can increase the strength of the gypsum like reinforcing bars in concrete.

Moreover, plaster is inherently fire-resistant. Even if burned, it emits virtually no toxic gases and, because it doesn't burn, is highly effective at preventing the spread of fire. Therefore, it is primarily used as a finishing material for interior walls and ceilings, and is particularly suitable for areas requiring curved or complex patterns.

Additionally, because it has a high density and smooth surface, it has excellent acoustic reflectivity, so it can be used in spaces where acoustic design is important, such as performance halls and auditoriums.

The above GRG non-combustible finishing material (110) can be filled in multiple layers in the space between each square steel pipe (100).

The GRG non-combustible finishing material (110) can be laminated in at least two layers with a thickness of approximately 60 mm or more, and one layer can be attached on site, followed by another layer.

That is, the square steel pipe (100) acts as a formwork and can be attached between the square steel pipes (100) and filled with hardening.

Furthermore, the GRG non-combustible finishing material (110) can be manufactured in advance in a mold form at the factory according to the on-site situation and then installed.

Meanwhile, a metal wire mesh (120) may be inserted and installed between each layer of the GRG non-combustible finishing material (110) laminated in two or more layers.

The above wire mesh (120) can perform functions of improving rigidity and sound wave reflectivity and dispersing resonant frequency between the GRG non-combustible finishing material (110).

Continuing, a PE film (130) and a damper sheet (140) can be attached and installed on the interior side of the GRG non-combustible finishing material (110) and the square steel pipe (100).

The above PE film (Polyethylene Film) is a thin film made of a plastic called 'polyethylene'. It is thin and soft, easy to handle, weighs almost nothing, and is difficult for water or moisture to pass through.

The above PE film (130) is divided into LDPE (low-density polyethylene), HDPE (high-density polyethylene), LLDPE (linear low-density polyethylene), etc. depending on the density, and in the present invention, high-density polyethylene can be used.

And the damper sheet (Damper Sheet: 140) effectively absorbs vibrations generated from metal plates and the like, and can particularly block high-frequency sound vibrations and attenuate low-frequency noise.

The order of attachment of the above PE film (130) and damper sheet (140) is not limited.

In addition, a plurality of environmentally friendly, non-flammable FG boards (150) that are adhesively fixed to the outer side of the PE film (130) and damper sheet (140) can be installed.

At least two FG boards (150) can be installed by laminating them with the same area as the PE film (130) and the damper sheet (140), and can be a board material that has been certified as environmentally friendly as a non-combustible material based on glass fiber.

The above FG board (150) is an abbreviation for 'Flexible Gypsum Board' and is a gypsum board that can be bent, but is also environmentally friendly and non-flammable. It may be an architectural finishing material with unique characteristics.

In addition, it is soft and elastic, so it is possible to implement 3D curves. It is highly versatile in interior design, such as adding curved designs to ceilings or walls or wrapping around columns.

Additionally, it has excellent sound insulation performance relative to its weight, and excellent processability and constructability.

Additionally, FG board (150) is fundamentally an eco-friendly, non-combustible board. It is made from natural minerals and has minimal environmental impact during its manufacturing process, making it environmentally friendly. It also reduces harmful substance emissions, contributing to indoor air quality.

Meanwhile, an insulation material (160) may be further installed on the concrete surface in contact with the multi-layer GRG non-combustible finishing material (110) in the space between the inside of the square steel pipe (100) and the square steel pipe (100).

The above insulation material (160) may be a polyester sound-absorbing insulation material, and since it does not clump even when wet and dries quickly, it can be manufactured in a form similar to an art board that can be attached to a wall and used as a soundproofing material.

Low melting point polyethylene terephthalate fiber is mixed with the main raw material fiber of polyester (PET) yarn (Polyethylene Terephthalate Staple Fiber) for adhesive purposes, and it acts as a binder that melts during heat processing and induces bonding between the fibers.

This allows for the formation of a strong bond between fibers without the need for a separate chemical adhesive, and the composition components can be blended in a specific ratio to optimize the density, strength, and sound absorption properties of the insulation.

The method for constructing a soundproof panel assembly having an increased acoustic reflectance by improving the surface density according to the present invention having the above configuration is described with reference to FIG. 4.

It includes a step (S100) of fixing square steel pipes with anchor bolts at regular intervals along a foundation structure at an appropriate distance, a step (S110) of laminating multiple layers of GRG fireproof finishing material between the square steel pipes and inserting wire mesh between each layer, a step (S120) of attaching a PE film and a damper sheet to the GRG fireproof finishing material and the interior surface of the square steel pipe, and a step (S130) of attaching an FG board to the outer side of the PE film and the damper sheet to improve the overall surface density.

Referring to Figure 3, first, a plurality of square steel pipes (100) can be installed side by side at an appropriate distance along an indoor wall and/or ceiling using anchor bolts (102). (S100)

And the space between the square steel pipes (100) is filled with multi-layered GRG non-combustible finishing material (110), and wire mesh (120) is inserted and installed between the GRG non-combustible finishing material (110) of each layer to perform the functions of improving rigidity and sound wave reflectivity and dispersing resonant frequency. Step (S110)

In step (S120), a PE film (130) and a damper sheet (140) are attached and installed on the interior side of the GRG non-combustible finishing material (110) and the square steel pipe (100), thereby blocking high-frequency sound vibrations and attenuating low-frequency noise.

Finally, in step (S130), at least two or more eco-friendly, non-flammable FG boards (150) can be installed to be adhesively fixed to the outer side of the PE film (130) and the damper sheet (140).

The above FG board (150) is soft and elastic, so it can implement a 3D curve. It is highly versatile in interior design, such as adding curved designs to ceilings or walls or wrapping around columns.

Meanwhile, FIG. 5 is a perspective view of another embodiment of a square steel pipe according to another embodiment of the soundproof panel assembly of the present disclosure, FIG. 6(a)(b) are cross-sectional views showing that the area of the square steel pipe in FIG. 5 is enlarged, and FIG. 7 is an enlarged cross-sectional view of part A in FIG. 6(b).

Buildings such as performance halls or auditoriums have many curved sections in their interior spaces, and in the curved sections, a curved square steel pipe (200) that can be installed in a different embodiment than the square steel pipe (100) of one embodiment is disclosed.

As shown in FIG. 5, the above-mentioned curved square steel pipe (200) may be composed of a first curved square steel pipe (210) and a second curved square steel pipe (220) of the same shape that faces and is joined to the first curved square steel pipe (210).

The above first curved rectangular steel pipe (210) may be composed of a first convex surface (212) facing the interior of the room, a first concave surface (214) installed in close contact with a curved section of the room, and a first vertical surface (218) connecting the first convex surface (212) and the first concave surface (214).

And, a first step surface (212a) with a thinner thickness is formed integrally by stepping on the lower surface of the first convex surface (212).

A stepped surface having a thinner thickness is formed on the lower surface of the first concave surface (214), and the stepped surface may be composed of a first concave contact surface (214-1), a second concave contact surface (214-2), and a third concave contact surface (214-3).

The above first concave contact surface (214-1), second concave contact surface (214-2), and third concave contact surface (214-3) can be installed side by side by being partitioned on a step surface.

And, referring to Fig. 7, the first concave contact surface (214-1), the second concave contact surface (214-2), and the third concave contact surface (214-3) may be provided with a spring (not shown) and a concave protrusion surface (216) that is connected to the spring and protrudes or compresses into the inner space.

The first curved square steel pipe (210) described above has a fastening hole (218a) formed through the first concave surface (214) and the first convex surface (212), and can be installed on a concrete surface as an anchor bolt (102) through the fastening hole (218a).

Additionally, a first insertion groove (218b) may be formed on the upper and lower sides of the first vertical surface (218).

The above first insertion groove (218b) may be in a convex shape and may be formed to be open to the outer surface.

And the first plate (219) can be inserted and installed by sliding into the first insertion groove (218b).

The above first plate (219) may have a length equal to or slightly smaller than the length of the first vertical surface (218) and may have a certain thickness.

And, a first insertion projection (219a) having the same shape as the first insertion groove (218b) can be formed integrally on the first plate (219).

The first plate (219) including the first insertion protrusion (219a) can be slidably inserted along the first insertion groove (218b), so that the first plate (219) can be installed facing each other on the upper and lower sides, perpendicular to the first vertical plane (218).

These first plates (219) may also be installed by forming a first insertion groove (218b) in a square steel pipe (100) of one embodiment.

The first plate (219) on the upper and lower sides can support and adhere the multi-layer GRG non-combustible finishing material (110) installed therebetween to increase the surface density.

Continuing, the second curved rectangular steel pipe (220) may also be configured with a second convex surface (222) facing the interior of the room, a second concave surface (226) that is installed in close contact with the curved section of the room, and a second vertical surface (228) that connects the second convex surface (222) and the second concave surface (226).

A second step surface (226a) with a thinner thickness is formed integrally by stepping onto the second concave surface (226).

The second step surface (226a) can be positioned in a surface contact manner by interlacing the first concave contact surface (214-1), the second concave contact surface (214-2), and the third concave contact surface (214-3) of the first curved rectangular steel pipe (210).

And, a stepped surface having a thinner thickness is formed on the upper surface of the second convex surface (222), and the stepped surface may be composed of a first convex contact surface (222-1), a second convex contact surface (222-2), and a third convex contact surface (222-3).

The above first convex contact surface (222-1), second convex contact surface (222-2), and third convex contact surface (222-3) can be installed side by side by being partitioned on a step surface.

And, as shown in Fig. 7, the first convex contact surface (222-1), the second convex contact surface (222-2), and the third convex contact surface (222-3) may be provided with a spring (223) and a convex protrusion surface (224) that is connected to the spring (223) inwardly and protrudes or compresses into the inner space.

A fastening hole (218a) penetrating the second concave surface (226) and the second convex surface (222) is also formed in the second curved square steel pipe (220) described above, and an anchor bolt (102) can be installed on a concrete surface through the fastening hole (218a).

Additionally, a second insertion groove (228a) may be formed on the upper and lower sides of the second vertical surface (228).

The above second insertion groove (228a) may be convex in shape and may be formed open to the outer surface.

And the second plate (229) can be inserted and installed by sliding into the second insertion groove (228a).

Since the plate has the same shape and effect as the first plate (219), a separate description thereof is omitted.

Accordingly, the second curved square steel pipe (220) can be combined with the first curved square steel pipe (210) and installed on a concrete surface using a fastening hole (218a) and an anchor bolt (102).

The first concave surface (214) of the first curved rectangular steel pipe (210) and the second concave surface (226) of the second curved rectangular steel pipe (220) are installed as curved concrete surfaces, and an FG board (150) capable of curved installation can be installed on the first convex surface (212) and the second convex surface (222).

Furthermore, the area of the curved square steel pipe (200) can be expanded and installed depending on the area of the concrete surface of the curved surface or the situation of the corner curved surface.

That is, the second step surface (226a) of the second curved rectangular steel pipe (220) is joined to the first concave contact surface (214-1), the second concave contact surface (214-2), and the third concave contact surface (214-3) of the first curved rectangular steel pipe (210) in an alternating manner, and likewise, the first convex contact surface (222-1), the second convex contact surface (222-2), and the third convex contact surface (222-3) are joined to the first step surface (212a) of the first curved rectangular steel pipe (210) in an alternating manner.

Here, to expand the convex or concave surface, the facing first curved square steel pipe (210) or second curved square steel pipe (220) can be expanded by pulling in one direction.

For reference, it can be enlarged according to the curved portion as in Fig. 6(a) and Fig. 6(b).

The surface can be expanded by moving to the first concave contact surface (214-1), the second concave contact surface (214-2), and the third concave contact surface (214-3) that are in surface contact with each other in an alternating manner from the first step surface (212a).

And, since when the first concave contact surface (214-1), the second concave contact surface (214-2), and the third concave contact surface (214-3) installed in parallel are exposed, a groove may be formed on the surface, and at the same time as the concave contact surface is exposed, the concave protrusion surface (216) that was compressed by the spring (not shown) protrudes to form a relatively flush surface with the first concave surface (214), preventing the formation of a groove, and allowing the product to be installed in close contact with the concrete surface.

In this way, the convex surface can be extended to the first convex surface (212) and the second convex surface (222).

The first convex contact surface (222-1), the second convex contact surface (222-2), and the third convex contact surface (222-3), which are in staggered contact with the first step surface (212a) of the first curved rectangular steel pipe (210), can be expanded while being exposed.

Again, as in FIG. 7, when the first convex contact surface (222-1), the second convex contact surface (222-2), and the third convex contact surface (222-3) that are staggered on the first step surface (212a) are sequentially exposed, the convex protruding surface (224) that is compressed while compressing the spring (223) protrudes, and depending on the degree of expansion, the convex protruding surfaces (224) can sequentially protrude by the restoring force of the spring (223) to form the same surface as the convex surface.

As described above, the acoustic reflectance is improved compared to the past due to the increase in surface density caused by the multi-layered GRG non-combustible finishing material, and the mid-to-high frequency reflection performance can be maximized.

Additionally, it provides negative resonance and low-frequency vibration blocking effects through film layers and sheets, and fire safety and eco-friendliness can be enhanced through the use of non-combustible GRG materials and FG boards.

Additionally, it has the effect of allowing both ceiling and wall construction based on a steel pipe frame.

The above illustrates and describes specific embodiments. However, the invention is not limited to the above-described embodiments, and those skilled in the art will readily appreciate that various modifications and implementations can be made without departing from the spirit and scope of the invention as set forth in the claims below.
