Description

Construction noise diffusion blocking device

The present invention relates to a noise emission blocking device that suppresses the spread of noise generated in various construction sites to the surroundings, and more particularly, it is installed in the open passage of a concrete building structure to open the noise generated in the indoor space. It relates to a construction noise emission blocking device that blocks spreading to the outside through a passage.

The walls and slabs of a reinforced concrete building are constructed by first reinforcing and constructing reinforcing bars and formwork according to the design, and then pouring concrete into the constructed formwork. The formwork accommodates reinforcement and is a space in which concrete is poured. During the curing of the poured concrete, it maintains the specified shape and dimensions, maintains moisture inside the concrete, and protects it from external influences.

In the case of a high-rise apartment or building with almost the same plan structure of the upper and lower floors, so-called gang form and Al form are used as formwork. Gangfoam is a formwork for the exterior wall of a building, and a cage for working scaffolding is usually mounted on the exterior surface of the building and is installed on the exterior surface of the top floor of the building. As the number of floors in the building rises, the gang form also rises. For example, after Gangfoam finishes curing the outer wall on the 10th floor, it goes up to the height of the 1st floor for the 11th floor. As a method of raising the gang form, there is a lifting method using a crane or a pushing method using a plurality of hydraulic actuators.

In addition, the Alform is a formwork for forming a surface facing an indoor space, such as a wall, an inner wall, or a ceiling surface of a building, and a portion for forming the outer wall of the building forms a certain interval with respect to the gang form. It goes without saying that the thickness of the wall is the thickness of the al-form with respect to the gang form.

Also, like most interior spaces, the interior space on each floor is opened to the outside through an open passage. The open passage is a square passage of various sizes to be installed in the future.

After the completion of curing of the concrete, the Alfoam and the gangfoam rise up to the height of one floor without separating the gangfoam, and the Alfoam is separated one by one by an operator within the corresponding floor and then transferred to the upper floor to wait for reuse.

However, the above-described construction method has the disadvantage of generating a large noise in the process of dismantling the Alform. In order to dismantle the alfoam, the operator has to tear off the alfoam attached to the inner wall or ceiling of the floor one by one, but the problem is that the torn alfoam falls freely and falls to the floor, generating a loud noise. The noise generated during the dismantling of the Alform spreads around the building construction site through the above-described open passage and acts as a cause of civil complaints.

Various technologies have been proposed to solve this problem, and among them, Korean Patent Publication No. 10-1717735 (gangfoam with insulation and soundproof structure) is included.

The prior publication discloses a technique of installing a shielding panel in a space provided by a horizontal panel and a vertical panel in order to block the opening space formed in the gang form. In particular, the opening space may be opened and closed if necessary by installing a hinged door on the shielding panel.

However, in the gangfoam of the prior art, since the shielding panel itself has a predetermined size, when the size of the opening changes, it has a limitation that it cannot flexibly cope with the size change. Unless the gangfoam is remanufactured to an appropriate size, proper soundproofing performance cannot be expected.

In addition, when the hinged door is closed, there is a problem that external light is blocked and the interior space is dark, which greatly deteriorates the work environment. The casement door cannot be closed if the indoor space is not equipped with lighting facilities.

Hereinafter, an embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Basically, the construction noise emission blocking device of the present invention is installed in an open passage formed on an outer wall of a building under construction to block the spread of construction noise generated indoors to the outside of the building.

The open passage is a square hole in which a window is to be installed. The sizes of open passages vary. If the open passage is wide and cannot be covered by a single blocking device, a plurality of blocking devices are connected to completely block the open passage.

Also, architectural noise is the noise generated in the indoor space of a building. For example, the sound of a grinder rotating in an indoor space, the sound of a drill, the sound of a hammer, and the sound of separate alfoam falling on the floor.

The construction noise emission blocking device of the present invention blocks the open passage formed on the outer wall of the building under construction, and prevents the noise generated in the indoor space from spreading to the outside of the building through the open passage. A hook portion detachably hung and fixed to the structure; It is fixed to the hook portion and has a basic structure including a flexible cover portion for blocking the emission of noise by covering the open passage while being suspended from the structure through the hook portion.

1 is a view for explaining an application method of the construction noise emission blocking device according to an embodiment of the present invention, Figure 2 is a view showing an enlarged portion A of FIG.

As shown, the gang form 15 and the cage 17 are fixed around the uppermost floor of the building 10 under construction. The gang form 15 is for forming the outer wall 12 of the building together with the AL form 14, and has a vertical plate 15a and a horizontal bar 15b and a vertical bar 15c supporting the plate 15a. .

The plate 15a is a plate-shaped formwork supported on the outer wall 12 of the lower layer, which has been cured through a separate fixing means. It goes without saying that the shape and width of the plate depend on the size of the exterior walls or windows.

The cage 17 is a structure in which a worker can enter and perform work, and is composed of a working scaffolding 17a and a safety railing (not shown), and the worker installs and dismantles the gang form on a high floor and subsequent plastering work, etc. Can be performed safely.

On the other hand, the building noise emission blocking device 30 according to the present embodiment has a basic structure of a hook portion 93 and a cover portion 91, and is set in a state that is detachably suspended from the structure around the open passage 13 do. The structure includes a gang form 15 or a cage 17 fixed on the uppermost open passage 13. In FIG. 2, the blocking device 30 is suspended from the horizontal bar 15b of the gang form 15, but the fixing point of the blocking device 30 may be changed as much as necessary.

The cover part 91 takes the shape of a substantially square plate and blocks the open passage 13 in a state suspended from the gang form 15, like a curtain, as shown in FIG. 7. In particular, when the size is smaller than that of the open passage 13, several can be connected to expand the entire cover area. Such a cover portion 91 has flexibility, may be folded or rolled up, and is not broken, so that it is easy to handle.

In particular, as will be described later, the light-transmitting sheet 41 may be applied to the cover part 91. The light-transmitting sheet 41 is a light passage for guiding light from outside the building to the indoor space 10a. Without the light-transmitting sheet 41, the cover portion 91 acts as a blackout film, and the indoor space 10a is dark, making it difficult to work, and the risk of a safety accident greatly increases.

The light entering the indoor space 10a through the translucent sheet 41 is reflected by the slab 11 and then reflected back to the light reflecting sheet 61d of the cover part 91 on the opposite side to keep the indoor space bright. Improve the working environment.

This blocking device 30 is shown in more detail in FIG. 3.

3 is an exploded perspective view for explaining the basic structure of the building noise emission blocking device 30 according to an embodiment of the present invention.

As shown, the cover part 91 is composed of a light introduction part 40 and a sound absorbing and insulating panel part 60 in the shape of a square plate. The light introduction part 40 and the sound absorbing and insulating panel part 60 may be attached to each other and used. If the light introduction part 40 is not required, a hook part 93 is installed on the top of the sound absorbing and insulating panel part 60, and only the sound absorbing and insulating panel part 60 can be used alone.

The light introduction part 40 includes a rectangular light-transmitting sheet 41 made of a transparent synthetic resin sheet, and connection velcros 43a and 43b fixed to four sides of the light-transmitting sheet 41. The light-transmitting sheet 41 is a transparent vinyl and acts as a window for light. The area of the light-transmitting sheet 41 may vary as needed.

The connection velcro (43a, 43b) is made of a velcro tape, which is a known adhesive cloth, in the form of a band, and is one of the coupling means for maintaining the coupling with the neighboring light introduction part 40 and the sound absorbing and insulating panel part 60.

A plurality of wire holes 43c are provided at the upper end of the light introduction part 40. The wire hole 43c is a hole into which the hook wire 46 of the hook portion 93 to be described later is fitted.

The sound-absorbing and insulating panel part 60 plays a role of sound-absorbing and sound-absorbing noise generated in an indoor space, taking the form of a direct signboard extending in a vertical direction, and connecting velcro (61f, 61g) on four sides of the outer part. ). The connection velcro (61f, 61g) is a coupling means for connecting the sound absorbing and insulating panel part 60 to the neighboring other sound absorbing and insulating panel parts 60 and the light introducing part 40.

For example, when the connection velcro 61f at the top of the sound absorbing and insulating panel part 60 is attached to the connection velcro 43b at the lower end of the light introducing part 40, the coupling of the light introducing part 40 and the sound absorbing and insulating panel part 60 is maintained. . Likewise, as shown in FIG. 7, when the connection velcro 61f on the side is attached to the connection velcro 61g on the side of the other adjacent sound absorbing and insulating panel part 60, the entire cover area of the sound absorbing and insulating panel part 60 is Can be expanded.

The sound-absorbing and insulating panel part 60 is wrapped with a finishing sheet 61a after stacking a plurality of functional layers, and has a laminated structure shown in FIG. 5.

5 is a cross-sectional view taken along line B-B of the sound absorbing and insulating panel unit 60 shown in FIG. 3.

As shown, the sound absorbing and insulating panel portion 60 has a laminated structure of a sound insulating panel 61b, a sound absorbing panel 61c, a light reflecting sheet 61d, and a finishing sheet 61a.

The sound insulation panel 61b is a viscoelastic synthetic resin plate having a certain thickness and collides with noise generated in an indoor space and reduces sound energy of the noise. Since the energy of the noise reaching the sound insulation panel 61b has already passed through the sound absorption panel 61c and is primarily attenuated, it is almost blocked by the sound insulation panel 61b.

The sound-absorbing panel 61c is a sound-absorbing layer laminated on the upper surface of the sound-absorbing panel 61b and is made of felt or fibers. The noise energy passes through the sound-absorbing panel 61c and is absorbed.

The light reflecting sheet 61d is a sheet-like member coated with aluminum on the glass cloth, and is exposed toward the indoor space 10a while covering the sound-absorbing panel 61c. Glass cross is a sheet-like member made of fiberglass, has excellent heat resistance and does not burn.

Since the glass cloth is coated with aluminum, the light reflective sheet has greater heat resistance and provides a texture similar to that of silver paper. In other words, it does not absorb and absorb light applied from the outside, but reflects most of it toward the interior space. As described with reference to FIG. 1, some of the light guided to the indoor space through the light-transmitting sheet 41 is reflected by the light-reflecting sheet 61d to keep the room brighter.

If necessary, waterproofness may be imparted to the light reflecting sheet 61d by forming the aluminum coating layer thickly. When the light reflecting sheet 61d has waterproof properties, moisture cannot penetrate into the sound absorbing and insulating panel unit 60, so that it is always kept dry.

The finishing sheet 61a is a tarpaulin fabric cut to an appropriate size, and covers the sound-absorbing panel 61b and the sound-absorbing panel 61c in a state where most of the light reflecting sheet 61d is exposed. The fixing of the finishing sheet 61a to the light reflecting sheet 61d may be performed using an adhesive method. However, when the waterproofing of the sound absorbing and insulating panel part 60 is not important, the light reflecting sheet 61d and the finishing sheet 61a may be fixed by a sewing method.

6 is a partial cross-sectional view illustrating another example of the sound absorbing and insulating panel unit 60 shown in FIG. 3.

The sound absorbing and insulating panel unit 60 shown in FIG. 6 includes a sound insulating panel 61b and a sound absorbing panel 61c of two layers. That is, from the bottom of the drawing, it has a laminated structure of the sound insulation panel 61b, the sound absorption panel 61c, the sound insulation panel 61b, the absorption panel 61c, and the light reflection sheet 61d. As the sound-absorbing panel 61b and the sound-absorbing panel 61c are built in each of two sheets, noise blocking efficiency is better than that of the type of sound-absorbing and insulating panel shown in FIG. 5.

Referring back to FIG. 3, it can be seen that the hook portion 93 includes a plurality of hook bands 45 and hook wires 46. As described above, the hook portion 93 serves to fix the cover portion 91 by hanging it from an external structure.

The hook band 45 is a belt-shaped Velcro having a certain width, and one end thereof is fixed to the connection Velcro 43b. Therefore, by attaching the hook band 45 to the gang form 15 and attaching the other end to the connection velcro 43b, for example, as shown in FIG. 7, the cover portion 91 to the gang form 15 is mounted. You lose.

The hook wire 46 is a metal wire extending in the longitudinal direction and is fitted into the wire hole 43c. In addition, hook portions 46a are located at both ends of the hook wire 46. The ring portion 46a is formed by bending both ends of the hanger wire 46 in a round shape, and for example, the end of a horizontal bar or a vertical bar among an external structure may be accommodated therein to receive a support force.

Reference numeral 46d is an auxiliary ring. The auxiliary ring 46d is used to connect the hook wire 46 to the external structure.

The hook band 45 or the hook wire 46 described above is an example of the hook part 93, as long as the cover part 91 can be suspended on an external structure, such as a gang form or a cage, the structure may vary. I can.

4 is a perspective view showing a modified example of the hook wire 46 shown in FIG. 3.

As shown, the branch line 46b is connected to the side of the hook portion 46a of the hook wire 46, and the hook 46c is fixed to the end of the branch line 46b. The hook 46c is a fixing means used by hanging on an appropriate part of the external structure. Whether to use the hook portion 46a, the hook 46c, or all of them is determined according to the site situation.

7 is a view showing an application example of the construction noise emission blocking device according to an embodiment of the present invention.

As shown, a plurality of blocking devices 30 are suspended from the gang form 15 in parallel. The reason for connecting the blocking device 30 is to cover the open passage 13 as a whole by expanding the entire area.

However, the hook portion 93 is omitted in the blocking device 30 located second from the right. Since there is no hook part 93, if necessary, the blocking device 30 may be separated from the blocking device 30 on the left or right and then turned over to one side. For example, it can be opened in the direction of arrow c.

By configuring to open some of the blocking devices 30 in this way, the operator can enter the indoor space 10a from the cage 17 through the open passage 13 (even though the blocking device 30 is installed). Or, it is possible to quickly move from the indoor space (10a) to the cage (17).

On the other hand, the blocking device 30 located on the rightmost side of FIG. 7 is not connected to the sound absorbing and insulating panel unit 60 by a light introduction unit 40 in a detachable manner, but to the sound absorbing and insulating panel unit 60 itself. ) Is applied. That is to say, a hole is made in a part of the sound absorbing and insulating panel part 60 and the light-transmitting sheet 41 is fixed therein. In this way, in order to achieve the purpose of light, the light-transmitting sheet 41 may be formed on the sound absorbing and insulating panel 60 itself.

8 is a view showing a modified example of the light introduction unit 40 shown in FIG.

As shown, it is possible to configure three light introduction portions 40 having the same size by overlapping them. Each light introduction part 40 includes a rectangular sheet-type transparent sheet 41 and an edge band 42 fixed to four edges of the transparent sheet 41. The edge band 42 is made of a synthetic resin sheet and acts to maintain the light-transmitting sheet 41 in an unfolded state.

In addition, overlapping velcros 31a and 31b are fixed on both sides of each edge band 42. The overlapping velcros 31a and 31b are arranged to face each other, and the three light introduction portions 40 maintain a tightly fixed state. By overlapping the plurality of light introduction parts 40 in this way, leakage of noise through the light transmitting sheet 41 is suppressed, thereby improving overall noise blocking efficiency.

9 is an exploded perspective view showing the sound absorbing and insulating panel unit 60 shown in FIG. 3 together with the auxiliary panel unit 70.

As shown, an auxiliary panel part 70 may be added to one side of the sound absorbing and insulating panel part 60. The auxiliary panel part 70 has the same size and stacked structure as the sound absorbing and insulating panel part 60, and is fixed to one side of the sound absorbing and insulating panel part 60 through overlapping velcros 31a and 31b, and It serves to double the performance.

10 is an exploded perspective view showing another example of a sound absorbing and insulating panel unit 60 applicable to the building noise emission blocking device according to an embodiment of the present invention, and FIG. 11 is a light diffusing body shown in FIG. 73) is a side cross-sectional view showing the combined state.

Hereinafter, the same reference numerals as the above-described reference numerals denote the same members having the same function.

Referring to the drawings, it can be seen that a square through hole 61e is formed in the sound absorbing and insulating panel part 60, and the light diffuser 73 is inserted and fixed in the through hole 61e.

The through hole 61e is a hole perforated in the thickness direction of the sound absorbing and insulating panel 60, and its inner surface is completely sealed using a finishing sheet 61a. It goes without saying that the position or size of the through hole 61e can be changed as needed.

The light diffuser 73 is a solid transparent block made of acrylic or plastic, and is combined within the through hole 61e to serve as a lens for guiding light from outside the building to the indoor space 10a.

The light diffuser 73 is composed of a first light-transmitting block 73a and a second light-transmitting block 73e. The first light-transmitting block (73a) takes the shape of a substantially hexahedron, but consists of a diffusion body (73b) having a rounded surface facing the indoor space (10a), and a fitting block (73c) integral with the diffusion body (73b). Done.

In addition, the second light-transmitting block 73e includes a substantially hexahedral diffusion body 73k having a rounded surface facing the outdoors, and a receiving block 73f integrally formed with the diffusion body 73k. The receiving block 73f is provided with a groove portion 73g. The groove portion 73g is a groove for accommodating the fitting block 73c.

The first and second light-transmitting blocks 73a and 73e are combined with each other and serve as a lens, so to speak, to guide light from outside the building to the indoor space 10a. External light passes through the second light-transmitting block 73e and the first light-transmitting block 73a and fills the indoor space 10a in a diffused state. The first and second light-transmitting blocks 73a and 73e serve as a light introduction part for guiding light from outside the building to the indoor space.

12 is a view showing another example of the sound absorbing and insulating panel unit 60 applicable to the building noise emission blocking device according to an embodiment of the present invention.

As shown, the lighting device may be incorporated in the sound absorbing and insulating panel part 60 which is a part of the cover part 91. The lighting device is for irradiating light into the indoor space 10a, and includes a plurality of lighting units 74, batteries 76, and switches 75.

The lighting unit 74 includes a plurality of LED lamps 74b disposed on the front surface of the light reflecting sheet 61d, and a circuit board 74a on which a driving circuit of the LED lamp 74b is formed. The circuit board 74a is embedded in the sound absorbing and insulating panel part 60. The light radiated from the LED lamp 74b is used as lighting to illuminate the indoor space. For example, it is possible to increase the work efficiency by turning on the LED lamp (74b) when working on a cloudy day or at night.

The switch 75 is connected to each of the lighting units 74 through an internal connection line 74c, and turns the LED lamp 74b on and off. The switching method of the switch 75 can be applied in various ways.

The battery 76 is a battery that can be charged through the charging line 77 and supplies power to the lighting unit 74. Lithium ion batteries or lithium polymer batteries can be used as batteries.

13A and 13B are views for explaining the configuration and operation of the seal holding unit 78 applicable to the construction noise emission blocking device according to an embodiment of the present invention.

The sealing holding part 78 is fitted around the cover part 91 to block a gap between the cover part 91 and the exterior wall 12 of the building, thereby preventing noise from falling through the gap.

Referring to the drawings, the sealing holding part 78 is a torsion spring connecting a pair of jaws 78b, a handle 78c provided at an end of the jaw 78b, and a jaw 78b configured to enable cross movement. 78d), consisting of a close contact cushion (78a) fixed to the outer portion of the jaw (78b) on one side. The jaw (78b) and the handle (78c) form one body.

The torsion spring (78d) is installed at the intersection of the jaws (78b) and provides elasticity in the direction in which the jaws (78b) retract. Thus, so to speak, when the handle 78c is closed in the direction of the arrow e and the jaws 78b are opened, the edge of the cover 91 is bitten between the jaws 78b and then the handle 78c is released, the jaws 78b Is closed by the action of the torsion spring and is fixed by biting the cover part 91 as shown in FIG. 13B.

The close contact cushion (78a) is located between the one side jaw (78b) and the outer wall (12) to block the leakage of noise. As long as this function can be performed, the structure of the adhesion cushion 78a can be variously changed, and for example, it may have a configuration in which the sound absorbing material is wrapped with a tarpaulin fabric.

14 is a view for explaining a zipper coupling method of each cover portion 91 in the building noise emission blocking device according to an embodiment of the present invention.

As shown, it can be seen that the sound absorbing and insulating panels 60 adjacent to each other are connected through the zipper 81. The sound absorbing and insulating panel unit 60 and the light introducing unit 40 shown in FIG. 7 are connected using a belt-shaped Velcro, and a zipper 81 can be used instead of Velcro. Furthermore, as long as the zipper 81 as well as the neighboring counterparts can be connected to be separated from each other, various other fastening methods can be applied. For example, it is also possible to use buttons, magnets, hooks and rings.

Referring to FIG. 14, in the two adjacent sound absorbing and insulating panel parts 60, a support band 81a and a zipper piece 81b on one side of the sound absorbing and insulating panel part 60, and the opposite sound absorbing and insulating panel part 60 ), it can be seen that the other side zipper piece 81c is provided.

The support band 81a is a strip-like member made of a non-stretch fabric, and has a zipper piece 81b at one end thereof in the width direction. The support band 81a passes over to the other sound absorbing and insulating panel part 60 in a state in which the two sound absorbing and insulating panel parts 60 are connected, so that the zipper piece 81b comes into contact with the other support part 81c. By applying the support band 81a, the joint portion of the sound absorbing and insulating panel portion 60 is covered, and sealing at the joint portion is reinforced.

It goes without saying that if the slider 81d is lowered in the direction of the arrow k in the state where both zipper pieces 81b and 81c are aligned with each other, the zipper pieces are fixed. The connection of the neighboring sound absorbing and insulating panels 60 is completed.

Such a zipper, of course, can also be applied to the connection between the sound absorbing and insulating panel unit 60 and the light introducing unit 40.
