Description

[Technical Field]

[0001] The present invention relates to a safety construction method for soundproofing panels. [Background technology]

[0002] One method for reducing noise caused by civil engineering work or work on temporary scaffolding around a construction site involves surrounding the perimeter of the construction site or temporary scaffolding with soundproofing panels. Since these soundproofing panels are at risk of collapsing or scattering to the surrounding area during severe weather accompanied by strong winds, such as a typhoon, safety measures to prevent these events must be implemented before the onset of severe weather. Safety measures for soundproofing panels include, for example, removing all soundproofing panels before the onset of severe weather accompanied by strong winds or firmly securing the panels. Another method involves replacing soundproofing panels with mesh sheets. For temporary scaffolding, there is also a method in which soundproofing panels attached to the perimeter of the scaffolding are attached so that they can be opened and closed freely, tilting approximately horizontally around one end of the panel on the outside of the scaffolding (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-197441 Summary of the Invention [Problem to be solved by the invention]

[0004] On the other hand, the above-mentioned methods of removing all soundproofing panels or firmly securing them have the problem of requiring a lot of time and effort. Furthermore, the method of removing all soundproofing panels has the problem of requiring reinstallation after bad weather, which requires even more time and effort. The method of using mesh sheets as a substitute has the problem of not being able to ensure the specified soundproofing performance because the soundproofing effect is reduced compared to soundproofing panels. The method of tilting soundproofing panels on temporary scaffolding to the outside of the scaffolding has the problem that if the soundproofing panels are left tilted, external forces such as strong winds may act on the soundproofing panels in bad weather, placing a large load on the connection between the soundproofing panels and the temporary scaffolding, causing the connection to break and the soundproofing panels to fall and fly away.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a soundproofing panel safety construction method that can easily implement safety countermeasures to prevent soundproofing panels from collapsing or scattering due to stormy weather accompanied by strong winds, without requiring much effort or time. [Means for solving the problem]

[0006] In order to achieve the above object, the soundproof panel safety construction method of the present invention comprises a soundproof panel wall formed by continuously installing soundproof panels, some of which are removable, in a polygonal shape around the outer periphery of an object to be soundproofed, and removing some of the soundproof panels except for corner panels that form each corner of the soundproof panel wall to form openings in the soundproof panel wall, and at least one opening is formed in each wall extending in one direction of the polygonal soundproof panel wall or in another direction perpendicular to that direction, and partition panels are provided between each corner of the soundproof panel wall and an end of the object to be soundproofed that is close to each corner of the soundproof panel wall to divide the space formed between the soundproof panel wall and the object to be soundproofed into multiple sections in a planar view.

[0007] With the above configuration, at least one opening is formed in each polygonal soundproof panel wall extending in one direction, and the space between the soundproof panel wall and the object to be soundproofed is divided into multiple spaces by the partition panels. The air flow in the space between the soundproof panel wall and the object to be soundproofed is blocked by the partition panels and is limited to each divided space. As a result, during stormy weather accompanied by strong winds, such as a typhoon, wind blowing toward one of the soundproof panel walls flows through the opening into the space divided by the partition panel, increasing the wind pressure (positive pressure) acting on the inner surface (space side) of one of the walls facing the wind. The increased positive pressure on the inner surface of one of the walls creates an equalizing effect between the wind pressure (positive pressure) caused by the wind blowing toward the outer surface (outside) of one of the soundproof panel walls and the positive pressure on the inner surface, thereby reducing the resultant force of the wind pressure acting on one wall (positive pressure acting in a direction pressing one wall toward the object to be soundproofed). Furthermore, on the outer surface (outside) of the other wall of the soundproof panel wall that is perpendicular to one of the above-mentioned soundproof panel walls, a separated flow occurs, in which wind blowing toward one wall flows away from the one wall. This separated flow causes a large wind pressure (negative pressure acting in a direction that causes the other wall of the soundproof panel wall to bend outward) to act on the other wall. On the inside (space side) of the other wall, the separated flow that has bent around to the other wall flows into the divided space through an opening, causing wind pressure (negative pressure acting in a direction that presses the other wall toward the object to be soundproofed). As a result, the negative pressure on the outer surface and the negative pressure on the inner surface of the other wall of the soundproof panel wall create a pressure equalization effect, which also reduces the resultant force of the wind pressure acting on the other surface (negative pressure acting in a direction that causes the other wall to bend outward). The effect of reducing wind pressure acting on the entire soundproof panel wall due to the above-mentioned pressure equalization effect can be realized for all of the polygonal soundproof panel walls, so that wind pressure acting on all of the soundproof panel walls can be reduced, preventing the soundproof panel walls from collapsing due to wind. Furthermore, with the above-mentioned configuration, soundproof panel safety measures can be implemented by simply removing some of the soundproof panels from each wall of the soundproof panel wall and installing partition panels in each corner of the space. This reduces the number of soundproof panels that need to be removed before stormy weather and reinstalled afterward, thereby reducing the work time and labor required for soundproof panel safety measures and allowing the work site to be restored and construction to resume in a short time after stormy weather. Furthermore, since safety measures for soundproofing panels can be implemented in a short period of time, they can be completed quickly even in the event of severe weather that is difficult to predict, such as a rapidly developing low pressure system.

[0008] In the soundproof panel safety construction method according to the present invention, the openings may be formed in a plurality of sections in each wall extending in one direction of the soundproof panel wall or in another direction perpendicular to the one direction.

[0009] With the above configuration, the desired pressure equalization effect can be achieved against the wind pressure of wind blowing toward a soundproof panel wall, even for a large soundproof panel wall with a large wall surface area, thereby preventing the soundproof panel wall from collapsing due to wind.

[0010] In addition, in the safety construction method for soundproofing panels of the present invention, the soundproofing object may be provided with temporary scaffolding on its outer periphery, the soundproofing panel wall may be provided on the outer periphery of the temporary scaffolding, and the partition panel may be provided within the temporary scaffolding.

[0011] By using the above configuration, the desired pressure equalization effect can be achieved against the wind pressure of wind blowing toward the soundproof panel wall, thereby preventing temporary scaffolding set up in the space between the soundproof panel wall and the object to be soundproofed from collapsing due to wind. In addition, since safety measures for soundproofing panels can be implemented without the need to dismantle temporary scaffolding before bad weather strikes, the work time and labor required for safety measures for soundproofing panels can be reduced, and the work site can be restored and construction can be resumed in a short time after bad weather strikes.

[0012] In the soundproof panel safety construction method according to the present invention, the soundproof panel wall may be constructed by installing a plurality of the soundproof panels so that they come into contact with the ground around the periphery of the object to be soundproofed.

[0013] With the above-mentioned configuration, even when the soundproofing panels are installed on the ground, the desired pressure equalization effect can be achieved against the wind pressure blowing toward the soundproofing panel wall, so that safety measures for the soundproofing panels can be implemented without the need to remove the installed soundproofing panels before stormy weather hits. This reduces the work time and labor required for safety measures for the soundproofing panels, and allows the work site to be restored and construction to resume in a short time after stormy weather. [Effects of the Invention]

[0014] According to the present invention, a safety construction method for soundproofing panels can be provided that can easily implement safety construction work to prevent soundproofing panels from collapsing or scattering due to stormy weather accompanied by strong winds, without requiring much effort or time.

DETAILED DESCRIPTION OF THE INVENTION

[0016] A safety construction method for soundproofing panels according to an embodiment of the present invention will be described below with reference to Figures 1 to 3. In this embodiment, a safety construction method for soundproofing panels provided on the outer periphery of temporary scaffolding provided on the outer periphery of a construction object will be described.

[0017] As shown in FIG. 1, soundproof panels 1 are attached to the outer building frame 31a of temporary scaffolding 3, which is set up around the periphery of an object 2 to be soundproofed, such as a construction site, and are set up around the periphery of the temporary scaffolding 3, which is a work space for construction work on the object 2 to be soundproofed. A plurality of soundproof panels 1 are set up consecutively in the height and width directions of the temporary scaffolding 3, forming a soundproof panel wall 4 that is rectangular in plan view and surrounds the periphery of the temporary scaffolding 3. The space between the soundproof panel wall 4, where the temporary scaffolding 3 is formed, and the object 2 to be soundproofed is referred to as the "work space 5." The temporary scaffolding 3 has multiple floors separated in the height direction by scaffolding boards.

[0018] The soundproof panel 1 may be configured, for example, by stretching a polyester fabric material within a known rectangular metal frame. The soundproof panel wall 4 has a bellows 32 attached to its periphery as a measure to prevent falling objects during work within the temporary scaffolding 3. The bellows 32 are attached to the middle of the soundproof panel wall 4 in the height direction, surround the periphery of the soundproof panel wall 4, and protrude outward. Hereinafter, the direction in which the pair of opposing walls 4a and 4b (walls extending horizontally in a plan view in FIG. 1(a)) of the soundproof panel wall 4 extend will be referred to as the X-direction, the direction in which the walls 4c and 4d (walls extending vertically in a plan view in FIG. 1(a)) that are perpendicular to the X-direction and perpendicular to the pair of walls 4a and 4b extend will be referred to as the Y-direction, and the direction perpendicular to the X-direction and Y-direction will be referred to as the Z-direction.

[0019] The object to be soundproofed 2 is, for example, a high-rise construction structure that is rectangular in plan view, such as a high-rise building under construction (hereinafter, the object to be soundproofed 2 will be referred to as the "construction object 2"). Within the construction object 2 and the temporary scaffolding 3, work noise is generated due to the use of construction machinery, etc.

[0020] The soundproof panel walls 4 are provided on the outer periphery of the temporary scaffolding 3, and provide soundproofing against work noise generated by work inside the construction object 2 and the temporary scaffolding 3. In addition to the soundproofing function, the soundproof panel walls 4 also have the function of keeping the work space inside the construction object 2 and the temporary scaffolding 3 warm and the function of preventing dust from entering the work space.

[0021] The temporary scaffolding 3 is connected to the construction object 2. There are no limitations on the method for connecting the temporary scaffolding 3 to the construction object 2, and one example of such a connection method is to drive an anchor with a clamp at one end into the construction object 2, and then attach the clamp at one end to the frame 31b of the temporary scaffolding 3 on the construction object 2 side.

[0022] The multiple soundproof panels 1 that make up the soundproof panel wall 4 are installed so that they can be removed freely. There are no limitations on the method for connecting adjacent soundproof panels 1, 1 to the building frame 31a of the temporary scaffolding 3. One method for connecting adjacent soundproof panels 1, 1 to the building frame 31a is to attach clamps having fixing claws that hook onto the adjacent soundproof panels 1, 1 to frame portions extending in the Z direction of the building frame 31a that face the adjacent soundproof panels 1, 1, and then engage the fixing claws to connect the adjacent soundproof panels 1, 1.

[0023] The soundproof panel wall 4 has corner panels 12 provided between corner panels 11 extending in the X direction and corner panels 11 extending in the Y direction that constitute each corner 41 of the soundproof panel wall 4, and the corners 41 are formed into a chamfered shape. The method of connecting the corner panels 11 and 12 to the temporary scaffolding 3 is not limited to the same method as the above-mentioned method of connecting adjacent soundproof panels 1, 1 to the temporary scaffolding 3. Hereinafter, a configuration in which the soundproof panel wall 4 is provided on the outer periphery of the temporary scaffolding 3 will be referred to as a soundproof structure 6.

[0024] The soundproof panel safety construction method of this embodiment is applied to the soundproof structure 6 when stormy weather accompanied by strong winds is predicted to occur at the construction site of the construction object 2. The steps of the soundproof panel safety construction method will be described below.

[0025] When severe weather accompanied by strong winds, such as a typhoon, is predicted at the construction site of the construction object 2, the soundproof structure 6 removes some of the soundproof panels 1 constituting the soundproof panel wall 4 before the severe weather occurs, as shown in FIG. 2 , to form openings 7 in the soundproof panel wall 4 (hereinafter, the removed soundproof panel 1 will be referred to as "removable panel 13"). One opening 7 is formed in each wall of the soundproof panel wall 4, which is formed in a rectangular shape in plan view, for a total of four openings 7 in the soundproof panel wall 4. At least one opening 7 is required in each wall of the soundproof panel wall 4, and multiple openings 7 are provided throughout the soundproof panel wall 4.

[0026] The removable panel 13 is any one of the multiple soundproofing panels 1 excluding the corner panels 11 and the corner panels 12. The opening 7 formed in the walls 4a and 4b is formed by removing one removable panel 13 located in the middle in the X direction and the middle in the Z direction. Similarly, the opening 7 formed in the walls 4c and 4d is formed by removing one removable panel 13 located in the middle in the Y direction and the middle in the Z direction.

[0027] In the soundproof structure 6, partition panels 8 are installed between the four corners 41 of the soundproof panel wall 4 and each end 21 (hereinafter, the end 21 will be referred to as the "corner 21") of the construction object 2 that faces each corner 41 diagonally in the X or Y direction (hereinafter, referred to as the "installation position 8a") before the occurrence of severe weather. The partition panels 8 are installed at the four installation positions 8a on each of the multiple floors of the temporary scaffolding 3 arranged in the Z direction, and the multiple partition panels 8 installed at the installation positions 8a on each floor divide the work space 5. The work space 5 is divided into four partition spaces 51 by dividing each floor of the temporary scaffolding 3 with the multiple partition panels 8 at the four installation positions 8a. The partition panels 8 are approximately the same height as the soundproof panels 1 in the Z direction and are made of a material that has higher strength against wind pressure than the soundproof panels 1.

[0028] The partition panel 8 is connected to the frame 31a located at the corner 41 on the corner 41 side. The method of connecting the partition panel 8 to the frame 31a at the corner 41 is not limited, and for example, the partition panel 8 may be connected by engaging with a clamp attached to the frame 31a, as with the corner panel 11 and the corner panel 12.

[0029] The partition panel 8 is connected to the construction object 2 at the corner 21. The method for connecting the partition panel 8 to the construction object 2 at the corner 21 is not limited, and for example, they may be welded together, or they may be connected by driving anchors with clamps, as with the temporary scaffolding 3.

[0030] After the occurrence of stormy weather accompanied by strong winds, all of the partition panels 8 installed before the stormy weather are removed, and the detachable panels 13 removed before the stormy weather are reinstalled, and work is resumed.

[0031] Next, the operation and effect of the soundproof panel safety construction method according to this embodiment will be described with reference to the drawings.

[0032] 1 and 2, the soundproof structure 6 is formed by removing removable panels 13 from each wall of a soundproof panel wall 4 that is installed in a rectangular shape in plan view on the periphery of temporary scaffolding 3 located on the periphery of a construction object 2 before the occurrence of severe weather accompanied by strong winds such as a typhoon. The soundproof structure 6 also has a plurality of partition panels 8 installed on each floor of the temporary scaffolding 3 at four installation positions 8a of the soundproof panel wall 4, and divides the work space 5 into four partition spaces 51 by partitioning each floor of the temporary scaffolding 3 at the four installation positions 8a.

[0033] With the above configuration, the soundproof structure 6 has one opening 7 formed in each of the four soundproof panel walls 4, which are rectangular in plan view, and the work space 5 is divided by four partition panels 8 into four divided spaces 51 facing the wall surface of each soundproof panel wall 4 facing the construction object 2. By forming the four divided spaces 51, the air flow within the work space 5 is blocked by each partition panel 8 and is limited to each divided space 51.

[0034] As a result, as shown in FIG. 3 , when wind 9 blows toward wall 4c of soundproof panel wall 4 during stormy weather accompanied by strong winds such as a typhoon, wind 9a flows into partition space 51 facing wall 4c through opening 7 formed in wall 4c (hereinafter, partition space 51 facing wall 4c will be referred to as "divided space 51a"). In soundproof structure 6, wind 9a flowing into partition space 51a increases wind pressure 91 acting on wall 4c within partition space 51a. Wind pressure 91 is a positive pressure (internal pressure) acting in a direction that causes wall 4c to bulge outward. Wind pressure 91 acts uniformly within partition space 51a.

[0035] Wind pressure 92 acts on the outer surface 42 of wall 4c. Wind pressure 92 is a positive pressure (external pressure) that acts in a direction that presses wall 4c toward the construction object 2. Wind pressure 92 is smallest near the boundary between wall 4c and wall 4a and increases with increasing distance from the boundary.

[0036] As described above, when wind pressure 91 acts within partition space 51a, wind pressure 93, which is the resultant force (difference) between wind pressure 91 and wind pressure 92 and is a positive pressure acting on the entire wall 4c in a direction pressing wall 4c toward construction object 2, can be reduced by the equalizing effect. The equalizing effect between wind pressure 91 and wind pressure 92 is exerted if wind pressure 93 can be reduced by increasing wind pressure 91.

[0037] Furthermore, on the outer surface 43 side of the wall 4a, which is perpendicular to the wall 4c, a separated flow 9b, which is part of the wind 9 and flows away from the wall 4c, is generated. A wind pressure 94 acts on the outer surface 43 side of the wall 4a due to the separated flow 9b. The wind pressure 94 is a negative pressure (external pressure) that acts in a direction in which the wall 4a expands outward. The wind pressure 94 is greatest near the boundary between the wall 4a and the wall 4c.

[0038] Wind 9c, which is part of the separated flow 9b, flows into the partition space 51 facing the wall 4a through the opening 7 in the wall 4a (hereinafter, the partition space 51 facing the wall 4a will be referred to as the "partition space 51b"). Within the partition space 51b, wind 9c causes a wind pressure 95 to act. The wind pressure 95 is a negative pressure (internal pressure) that acts in a direction that presses the wall 4a toward the construction object 2. The wind pressure 95 acts uniformly within the partition space 51b.

[0039] As described above, when wind pressure 95 acts within partition space 51, wind pressure 96, which is the resultant force (difference) between wind pressure 94 and wind pressure 95 and acts on the entire wall 4a in the direction in which wall 4a bends outward, can also be reduced by the pressure equalization effect. The pressure equalization effect between wind pressure 94 and wind pressure 95 is exerted if wind pressure 96 can be reduced by the action of wind pressure 95, similar to the pressure equalization effect between wind pressure 91 and wind pressure 92 described above.

[0040] The effect of reducing the wind pressure acting on the soundproof panel wall 4 due to the pressure equalization effect between the walls 4c and 4a can be realized on all four walls of the soundproof panel wall 4. As a result, the wind pressure acting on each wall due to wind blowing from outside can be reduced on all four walls of the soundproof panel wall 4, and the soundproof panel wall 4 can be prevented from collapsing due to the wind.

[0041] Furthermore, with the above configuration, soundproof panel safety measures can be implemented by the simple task of removing the removable panels 13 from each wall of the soundproof panel wall 4 and installing multiple partition panels 8 at each corner of the work space 5. This reduces the number of removable panels 13 that need to be removed before stormy weather and reinstalled afterward, reducing the work time and labor required for soundproof panel safety measures and allowing the work site to be restored and construction to resume in a short time after stormy weather. Furthermore, because soundproof panel safety measures can be implemented in a short time, soundproof panel safety measures can be completed quickly even in stormy weather that is difficult to predict, such as a rapidly developing low pressure system.

[0042] Furthermore, the wind pressure acting on the soundproof panel walls 4 can be reduced due to the wind equalizing effect of the above-mentioned walls, which can prevent the temporary scaffolding 3 installed in the work space 5 from collapsing due to wind. Furthermore, because soundproof panel safety measures can be implemented without the need to dismantle the temporary scaffolding 3 before bad weather, the work time and labor required for soundproof panel safety measures can be further reduced, and the work site can be restored and construction can be resumed in a short time after bad weather.

[0043] The above describes an embodiment of the safety construction method for soundproofing panels according to the present invention, but the present invention is not limited to the above embodiment and can be modified as appropriate within the scope of the spirit thereof.

[0044] For example, in the above embodiment, one opening 7 is formed in each wall of the soundproof panel wall 4, for a total of four openings 7 in the soundproof panel wall 4, but the conditions such as the opening location, size of the openings, and number of openings are not limited to those described above as long as the desired soundproof panel safety effect can be obtained. For example, as shown in Fig. 4(a), a configuration may be adopted in which multiple openings 7 are provided in the Z direction in each wall of the soundproof panel wall 4 (wall 4c is shown as an example in Fig. 4(a)), or as shown in Fig. 4(b), openings 7 may be provided by removing all soundproof panels 1 that are installed consecutively in the Z direction in each wall of the soundproof panel wall 4 (wall 4c is shown as an example in Fig. 4(b)).

[0045] The conditions for the formation position, size, number of openings 7, etc. are determined so as to obtain the desired soundproof panel safety effect, taking into consideration the strength of the wind force of the wind 9a blowing into each divided space 51 and the size of the soundproof panel wall 4. For example, when multiple openings 7 are provided in each wall of the soundproof panel wall 4, measures such as reducing the opening area of ​​each opening 7 are taken to prevent wind 9a from blowing through the multiple openings 7.

[0046] For example, in the above embodiment, the soundproof structure 6 is configured such that the soundproof panel wall 4 is attached to the periphery of the temporary scaffolding 3. However, the soundproof structure 6 may also be configured such that the soundproof panel wall 4 has each soundproof panel 1 installed on the ground around the periphery of the construction object 2. By applying the soundproof panel safety measures to the above soundproof structure 6, it is possible to prevent the collapse or scattering of soundproof panels due to severe weather accompanied by strong winds, even for soundproof panels 1 installed in locations other than temporary scaffolding, such as the boundary between a work site and a road. Furthermore, the work time and labor required for soundproof panel safety measures can be reduced, allowing the work site to be restored and construction to be resumed in a short time after severe weather.

[0047] For example, in the above embodiment, the soundproof panel safety measure construction method is applied to a construction object 2 that is rectangular in plan view, but it is not limited to the above as long as the desired soundproof panel safety measure effect is obtained, and it may also be applied to a construction object 2 that is circular in plan view, for example.
