The soundproof shutter mounting structure 1 of the present embodiment is used as shown in Fig. 1 in a state in which the sound insulating wall W is erected on the side portion of the expressway R and viewed from the outer side (back side) of the expressway R. The composition. The sound insulating wall W is a H-shaped steel shutter mounting post (hereinafter simply referred to as a pillar) that is vertically erected at a constant interval along the longitudinal direction of the road R and in a position in which the adjacent groove portions M are opposed to each other. A plurality of soundproof shutters 3 are fixed between them. The soundproof shutter 3 absorbs sound generated in the road to prevent or suppress sound leakage to the outside of the road, and is provided on the pillar 2 from the inner side (front side) of the road. The soundproof wall W is mounted in a state of being vertically overlapped so as to have a predetermined height.

As shown in Fig. 1, a mounting portion 2a for fixing to the side wall S of the expressway R is provided at a lower end portion of the strut 2, and an anti-pillar drop cable 6 is inserted into the mounting portion 2a. Since the anti-pillar drop cable 6 is connected to a plurality of pillars, even if the attachment portion 2a of the pillar 2 is detached from the side wall S due to a collision of the automobile or the like, the pillar 2 can be prevented from falling down the road.

The sound insulating shutter 3 shown in Fig. 3 is constructed by combining a punching metal plate 7 located on the front side of the inner side of the road with the outer cover 9. The cover 9 is a box-shaped member that is open on one side, and accommodates the sound absorbing material 8 therein, and the punched metal plate 7 is configured to close the opening of the cover 9.

The threaded hole 11 of the mounting portion 10 is fixed to the front wall 2f of the pillar 2.

The soundproof shutter 3 is mounted such that the punched metal plate 7 is located inside the road, and the sound generated in the road passes through the through hole of the punched metal plate 7, and is absorbed by the sound absorbing material 8 in the outer cover 9. This prevents or suppresses sound leakage to the outside of the road.

The sound absorbing material 8 can be used generally. In general, a fibrous body such as glass wool or polyester is used, and a porous body such as a polyurethane foam or a powder sintered body such as ceramics may be used. The type is not particularly limited. Further, when a fibrous body is used as the sound absorbing material 8, a protective film such as anti-scattering is preferably provided.

The thickness of the outer cover 9 is formed by forming a rib extending in the width direction so that the central portion in the height direction is slightly thin and the upper and lower end portions are thick, so as to secure the strength of the external force with respect to the thickness direction. In the center portion, an anti-drop metal member 13 to be described later is disposed.

The anti-drop metal member 13 is disposed on the back side of the soundproofing shutter 3, and the plurality of soundproofing shutters 3 are connected by inserting the anti-drop cable 14 for the shutter into the anti-drop metal member 13. This prevents the soundproof shutter 3 which is deformed by the collision of the automobile or the like and falls from the pillar 2 to the road.

Inserting the shutter with the anti-drop cable 14 into the anti-drop metal member 13, and connecting or connecting the plurality of shutters to each other by the anti-drop cable 14 for the shutter, thereby arbitrarily When the soundproof shutter is detached from the support 2, the shutter can also be prevented from falling.

As shown in Fig. 4 and Fig. 5, the fall prevention metal member 13 is bent into a rod-like member having a circular cross section (in the present embodiment, The steel wire of 8 is made of a spiral portion 15, a rod portion 16, and a fixing portion 17, and is directly fixed to the back surface of the outer cover 9.

As shown in Fig. 1, the shutter-preventing cable 14 is used to connect a plurality of sound-insulating shutters 3 connected to one pillar 2. In the first drawing, only the anti-drop cable 14 for the pillar mark of the center is used, and the description of the portion which is not visually recognized is omitted for the pillars at both ends. Both ends (front end 14a, terminal 14b) of the shutter-preventing drop cable are fixed in the vicinity of the lower end in the groove portion M of the strut 2. The starting end 14a of the shutter anti-drop cable 14 is fixed to the groove portion M on the right side of the figure, and is pulled back to the upper side of the strut 2, and the anti-shock shielding plate 3 on the left side is shown from the upper side to the opposite side. The drop metal piece 13 is inserted. Then, a certain length of excess length is provided at the lower end portion of the strut 2, and the anti-drop metal member 13 of the sound insulating shutter 3 opposite to the right side is inserted from the lower side, and is lowered in the groove portion M on the left side of the figure, and The terminal 14b is fixed in the groove portion M.

The spiral portion 15 of the drop prevention metal member 13 is bent into a spiral shape, and the insertion portion 18 through which the fall prevention cable 14 for the shutter is inserted is partitioned at the center portion. Further, the number of windings of the spiral portion 15 is not easily detached from the shutter fall prevention cable 14 when the soundproof shutter 3 is detached from the stay 2 The degree may be different depending on the pitch D of the spiral, but the function can be ensured as long as it is substantially two or more.

The pitch D of the spiral is preferably a plugging operation for the shutter fall prevention cable 14 described later with reference to Fig. 6, and is preferably equal to or larger than the diameter of the fall prevention cable 14 for the shutter. As will be described later, the shutter-preventing cable 14 is inserted into the insertion space 18 of the spiral portion through the gap 19 of the spiral portion 15. Further, the front end 15a of the spiral portion 15 must be an open end. For example, a barb or the like may be provided at the front end 15a of the open end so as to prevent the shutter from falling off the fall prevention cable 14.

The rod portion 16 extends from the lower end of the spiral portion 15 along the axis of the spiral portion 15, and the lower end is bent substantially 90° to become the fixed portion 17. In order to ensure the insertion operation of the shutter fall prevention cable 14 in order to ensure the space between the fixing portion 17 and the spiral portion 15, the rod portion 16 is provided as needed, and it is sufficient that the length is approximately several centimeters.

The fixing portion 17 extends in a direction intersecting the axis of the spiral portion 15 in the direction orthogonal to the axis in the present embodiment, and the falling prevention metal member 13 is fixed by the male screw 17b provided at the front end. On the back of the soundproofing shutter 3. As shown in FIG. 3, the fixing portion 17 is inserted into the fixing hole 22 provided on the back surface of the outer cover 9, and is directly fixed to the outer cover by screwing the locking nut 20a and the fixing nut 20b to the male thread 17b. 9 on the back side. At this time, the spiral axis of the spiral portion 15 is preferably arranged in the direction along the short side direction of the sound insulating shutter 3.

Fig. 6 is a view showing a step of inserting the shutter with an anti-drop cable into the anti-drop metal member. In order to insert the shutter with an anti-drop cable In order to prevent the falling of the metal member, the intermediate portion of the shutter with the drop-proof cable 14 is inserted into the gap 19 of the spiral portion 15, as indicated by the arrow 90, so that the shutter is prevented from being dropped by the cable 14 along the spiral The portion 15 moves in the gap 19 and is inserted into the insertion space 18 from the front end 15a of the spiral portion 15. Thereby, the anti-drop metal member 13 can be inserted from the intermediate portion of the shutter anti-drop cable 14 to facilitate the attachment and detachment between the two.

The fall prevention metal member 13 bends one rod-like member to form a spiral portion, and the shutter prevents the drop cable 14 from passing through the insertion space partitioned by the spiral portion, thereby preventing the connection. The falling metal member 13 and the fall prevention cable 14 for the shutter are not easily detached once the shutter is connected to the fall prevention cable 14. Further, since it is not combined with a plurality of members or a part of the annular portion is movable, it is easy to manufacture. Further, although the fall prevention metal member 13 is exposed to wind and rain for a long time during use, since there is no joint portion or movable portion as described above, there is no problem such as looseness or breakage, and quality does not occur over time. Sexual deterioration.

Fig. 7 is a perspective view showing another configuration example of the falling prevention metal member. In the anti-drop metal member 13 shown in Fig. 5, the fixing portion 17 having a circular cross section is screwed to the back side of the sound insulating shutter 3, and when the locking strength of the nuts 20a, 20b is insufficient, the prevention The dropped metal member 13 sometimes rotates and falls off.

In order to eliminate this problem, as shown in FIG. 7 , an anti-rotation pin 21 as an example of the anti-rotation portion is protruded from the rod portion 16 so as to be connected in parallel with the fixing portion 17 , and the anti-rotation pin is attached. The front end portion of the 21 is inserted into the insertion hole 23 provided in the soundproof shutter 3, thereby preventing the opening The rotation of the falling metal piece 13a.

Fig. 8 is a perspective view showing another configuration example of the falling prevention metal member. Figure 9 is a partially enlarged perspective view of the drop-proof metal member of Figure 8. The anti-drop metal member 24 shown in Fig. 8 is attached to the fixing portion 25 so as not to be rotatably with respect to the sound insulating shutter 3, as described above, in order to prevent the falling prevention metal member from falling off. .

As shown in Fig. 9, the fall prevention metal member 24 is formed by cutting the side surface of the male screw 26 of the fixing portion 25 to form the flat portion 27, and the cross-sectional shape of the fixing portion 25 is substantially elliptical. By forming the cross-sectional shape of the fixing portion 25 into a non-circular shape and forming a fixing hole 28 corresponding to the long hole shape of the cross-sectional shape as shown in FIG. 10, the fixing portion 25 can be fitted into the fixing hole 28, so that The fall prevention metal member 24 does not rotate around the fixing portion 25.

As shown in Fig. 10, the fixing of the soundproof shutter 3 and the fall prevention metal member 24 can be performed by using the loose nut 20a and the fixing nut 20b disposed on both sides of the outer cover 9 of the soundproof shutter 3.

Further, in the modification of the embodiment, as shown in Fig. 11, the fall prevention metal fitting 24a may be configured to eliminate the rod portion and directly connect the spiral portion 15 and the fixing portion 25.

Fig. 12 is a perspective view showing another configuration example of the falling prevention metal member. The anti-drop metal member 29 shown in Fig. 12 is provided with a flange portion 30 at a base portion of a male screw 26 having a circular cross section, and the flange portion 30 is provided with a rotation preventing rib 31. The cross-sectional shape of the fixing portion 25 composed of the rotation preventing rib 31 and the male screw 26 is formed into a non-circular shape. shape.

In this configuration, the fixing hole provided on the back surface of the shutter is formed along the shape of the outer edge of the rotation preventing rib 31 and the male screw 26, and the fixing portion 25 is inserted into the abutting surface of the flange portion 30. At 30a, the anti-drop metal member 29 can be prevented from rotating about the male thread 26. Further, the flange portion 30 does not require the loose nut 20a attached to the back side of the sound insulating shutter 3.

Next, the step of attaching the above-mentioned soundproof shutter 3 between the pillars 2 and 2 adjacent to the expressway will be described.

As described above, the soundproof shutter 3 is fixed to the front side of the front wall 2f of the pillars 2, 2. First, as shown in Fig. 1, this operation is to fix both ends of the shutter fall prevention cable 14 to the lower portion of the pillar 2, and to form the laying path shown in Fig. 1 along the pillar 2, Configured with a certain amount of excess length. When the shutter-preventing cable 14 is fixed to the pillar 2, it is not connected to each of the soundproof shutters 3.

Then, using the above-described steps, the shutter is prevented from being inserted into the insertion space 18 of the falling prevention metal member 13 provided on the back side (outer side) of the sound insulating shutter 3 by the fall prevention cable 14. As described above, since the shutter-preventing cable 14 is laid by the excess length, the shutter can be pulled by the fall prevention cable 14 toward the front side of the pillar 2 to perform the insertion operation.

In this manner, the attachment portion 10 to which the fall prevention metal member 13 and the soundproof shutter 3 for the shutter fall prevention cable 14 are connected is brought into contact with the front side of the front wall 2f of the pillar 2, and the screw hole 11 and the through hole are provided. The bolt insertion hole of the front wall 2f is anastomosed, and the soundproof shutter 3 is made by the bolt and the nut 12 Fixed to the pillars 2, 2.

In addition, the unloading of the soundproof shutter 3 can be performed by the reverse of the above steps, the soundproof shutter 3 is removed from the pillars 2, 2, and the fall prevention metal member 13 and the fall prevention cable for the shutter are released. The connection of line 14 is performed.

In the same manner, the soundproof shutter 3 and the shutter fall prevention cable 14 are connected in the same manner, and the soundproof shutter 3 is placed in the vertical direction. In the present embodiment, since the spiral shafts of the shutter fall prevention cable 14 and the spiral portion 15 are provided along the short side direction of the sound insulating shutter 3, the soundproof shutter 3 is retracted in the vertical direction. The hand can be easily touched by the fall prevention metal member 13 or the fall prevention cable 14 for the shutter, and the loading and unloading operation can be performed, and the work efficiency can be improved.

For example, when the automobile collides with the sound insulating wall W constructed as described above, the soundproof shutter 3 is pressed in a state of being bent and deformed toward the outside of the road, but since the shutter is fixed between the pillars 2 by the fall prevention cable 14, The anti-drop metal member 13 protrudingly disposed on the sound insulating shutter 3 is coupled to the anti-drop cable 14 for the shutter. Therefore, even if the sound insulating shutter 3 is detached from the pillars 2 on both sides, the shutter can be used by the shutter. The fall prevention cable 14 is suspended and supported without falling to the bottom.

According to the present embodiment, when only the damaged soundproof shutter 3 is replaced, the soundproof shutter 3 and the shutter fall prevention cable 14 are attached and detached, and the intermediate portion of the shutter can be removed from the shutter. Therefore, in the replacement work of the soundproof shutter 3, it is not necessary to remove the shutter fall prevention cable 14 from the stay 2. In addition, since the soundproof shutter 3 can be pulled out to the front (front) side of the road by the excess length of the fall prevention cable 14 by using the shutter, There is an advantage that it can be operated from the inside of an expressway.

In the first fall prevention metal fitting 24a, the spiral portion 15 is wound rightward, as opposed to Here, in the second fall prevention metal member, the spiral portion 46 is wound toward the left.

In the present embodiment, as shown in Fig. 15, the fall prevention metal members 24a and 45 are arranged such that the front ends 15a and 46a of the spiral portions 15 and 46 are disposed at a position more than the position in the extending direction of the fixing portion 17 Around the location. Thereby, even if the shutter 42 is deviated from the pillar and is in a state of being suspended by the anti-drop cable for the shutter, the cable can be prevented from entering the spiral gap from the front end position, and the shutter is not easily prevented. The detachment of the cable 14 is dropped. In the present embodiment, it is configured to generate an excess winding of about 40° with respect to the extending direction of the fixing portion 17.

In Fig. 13, different anti-drop metal members 24a, 45, respectively, are attached to both ends of the shutter 42. By changing the orientation of the spiral of the metal members attached to the left and right sides, when the shutter 42 is detached from the stay 2 and is dropped by the shutter with the fall prevention cable 14, the orientation of the spiral is affected. The anti-drop cable 14 for the shutter sometimes twists to the right or left, but the anti-drop metal member 24a, 45 is surely formed to be reversely rotated with respect to either of the anti-drop metal members 24, 45, thereby having an anti-drop cable for reducing the shutter. The effect of the line 14 from the possibility of naturally preventing the falling metal piece from being detached. On the other hand, when the shutter is mounted and the unloading operation is performed, the loading and unloading operation of the shutter anti-drop cable 14 can be separately performed, so that the burden of work is not increased.

In addition, the two types of anti-drop metal parts 24a, 45 are not required Two types of one shutter are provided, and for example, two types of shutters in which the same anti-drop metal member is attached to the right and left mounting positions may be combined. For example, the shutter to which the second fall prevention metal fitting 45 is attached may be arranged in the longitudinal direction (the short side direction of the shutter) on the shutter on which the first fall prevention metal member 13 is attached.

As described above, according to the sound insulating shutter mounting structure of the present embodiment, the fall prevention metal member 13 and the shutter for the soundproof shutter 3 can be provided from the intermediate portion of the shutter fall prevention cable 14. Since the anti-drop cable 14 is attached and detached, it is not necessary to disassemble the anti-drop cable 14 for the shutter, and only the damaged single-piece shutter can be removed for replacement.

The present invention is not limited to the above embodiment, and may be implemented in other various forms. For example, the fall prevention metal member 13 is configured by bending a rod member as shown in Fig. 6, for example, the male screw portion may be directly mounted at an intermediate position of the spiral portion 15, and Both ends of the spiral portion 15 are opened to be formed.

Further, the shape of the fixing portion for preventing the rotation of the falling prevention metal member from being non-circular is not limited to a substantially elliptical shape, and may be other shapes.

Further, in the above-described embodiment, the spiral portion is formed in a spiral shape having a spiral shape excellent in hanging support. However, for example, it may be configured to have a spiral shape in a single plane. According to this configuration, it is also possible to carry out the loading and unloading of the drop-proof metal member and the anti-drop cable for the shutter from the intermediate portion of the shutter for preventing the drop cable, and even if the shutters are detached from the pillars, The falling of the soundproof shutter can be prevented.

Further, although the above-described embodiment has been described with respect to the sound insulating shutter mounting structure, the same can be applied to, for example, a mounting structure for concealing the inside and the outside of the blind shutter. Further, in addition to being installed along the road, it is also applicable to the installation of a curtain wall for a building or the like which is installed between the pillars disposed between the partitions.

By appropriately combining any of the above embodiments, it is possible to achieve the respective effects. The present invention has been fully described in detail with reference to the accompanying drawings. It is to be understood that the modifications and variations are intended to be included within the scope of the invention as set forth in the appended claims.
