[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-159500 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a soundproof wall is erected above a base fixed to the ground surface and the base and soundproof wall are secured together with bolts, if the bolts are close to the ground surface, there is a risk that the protruding bolt covers will rub against the pipes, etc., and be damaged when the pipes, etc. are laid on the ground surface after the soundproof wall is constructed.

[0005] The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a protective member and a soundproof wall that do not damage pipes, etc. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means.

[0007] (1) A protective member according to one aspect of the present invention includes an attachment portion that is attached to a soundproof wall and a joint that protrudes from the soundproof wall. The joint is formed over the At a position away from the joint on the extension of the protruding direction of In a shape that overlaps with the joint and a protective plate having an opening formed therein.

[0008] The protective member of the present invention, which is specified by such characteristics, can protect the pipes, electric wires, etc. from contacting the joints even when the pipes, electric wires, etc. are installed close to a soundproof wall. The protective member has a protective plate and an attachment part, each of which has its own function, and therefore can protect the pipes, etc. collectively from contacting the multiple protruding joints without covering each of the multiple protruding joints individually. In addition, the protective plate has an opening, so that even after the protective member is attached to the soundproof wall, the soundness of the joints, such as whether they are loose, can be visually confirmed without removing the protective member, and repairs such as retightening can be made as necessary.

[0009] (2) In the above (1), a pit cover support portion may be provided for supporting a pit cover that closes a pit along the soundproof wall.

[0010] The protective member of the present invention, which is specified by such features, is provided with a pit lid support portion, and thus serves both to protect the piping, etc. from contact with the joint and to support the pit lid, making it possible to omit the provision of a separate structural member for supporting the pit lid.

[0011] (3) In the above (1) or (2), a closing portion may be provided to close a gap formed between the soundproof wall and a sound-absorbing panel.

[0012] The protective member of the present invention, which is specified by such characteristics, can close the gap formed between the sound-absorbing panel and the sound-insulating wall, thereby preventing people's feet from getting caught in the gap, suppressing the intrusion of rainwater, dust, etc. into the soundproof wall through the gap, and providing a neat and attractive appearance with few irregularities.

[0013] (4) In any of the above (1) to (3), the plate may be formed by bending a single plate material.

[0014] According to the protective member of the present invention specified by such features, it is possible to cover a plurality of protruding joints collectively. In addition, the protective member can be integrally formed with the protective plate, mounting portion, pit cover support portion, and closing portion, each of which has different functions, by press molding a single plate material. Then, processing to form the opening and the locking hole can be performed before or after press molding. In this way, since the protective member has parts with different functions integrally formed by bending molding from a single plate material, it can be manufactured at low cost and construction time can be shortened compared to attaching covers individually to the plurality of protruding joints.

[0015] (5) A soundproof wall according to one aspect of the present invention, in any one of (1) to (4) above, may include a base, posts standing upward from the base, a sound-absorbing panel spanning between adjacent posts, and the protective member attached to the posts.

Fig. 7 is an explanatory diagram showing a protective member attachment step in the construction method of the soundproof wall 100. Figs. 4 to 7 show the view of arrow A in Figs. 1 to 3.

[0020] As shown in FIG. 1, a protective member 40 according to this embodiment can be applied to a soundproof wall 100, for example. The soundproof wall 100 is provided at a position that separates a sound source from a space in which it is desired to suppress the propagation of sound from the sound source. The soundproof wall 100 is a plate-like body extending upward from the ground or a floor (hereinafter referred to as "ground surface, etc. G"). The lower end of the soundproof wall 100 is fixed to the ground surface, etc. G. The upper end of the soundproof wall 100 may be a free end. The soundproof wall 100 may be formed into a planar shape extending horizontally by arranging and linking a plurality of soundproof wall panel units 20 in the horizontal direction. The soundproof wall 100 comprises a base 10, a soundproof wall panel unit 20 standing upward from the base 10, a joint 30 connecting the base 10 and the soundproof wall panel unit 20, and a protective member 40 attached to the soundproof wall panel unit 20. In detail, the soundproof wall 100 comprises a base 10, pillars 21 standing upward from the base 10, sound-absorbing panels 22 spanning between adjacent pillars 21, and protective members 40 attached to the pillars 21. This allows the soundproof wall 100 to be easily constructed. It also prevents people's feet from getting caught in the gaps e in the soundproof wall 100, inhibits rainwater, dust, and the like from entering the interior of the soundproof wall 100 through the gaps e, and allows the soundproof wall 100 to have a neat, attractive appearance with few irregularities.

[0021] The base 10 includes a base 11 that can be fixed in direct contact with the ground surface G, and a soundproof wall panel unit mounting portion 12 that extends upward from the base 11.

[0022] The base 11 has sufficient rigidity, strength, and size to support the weight of the soundproof wall 100 above the ground surface or the like G and to withstand external forces such as a toppling moment acting on the soundproof wall 100. The base 11 has, for example, a cubic shape.

[0023] The soundproof wall panel unit mounting portion 12 is a portion for mounting the soundproof wall panel unit 20. The soundproof wall panel unit mounting portion 12 has a locking portion 12a capable of locking a joint 30 such as a bolt and a nut. The soundproof wall panel unit mounting portion 12 protrudes upward from the base 11. The soundproof wall panel unit mounting portion 12 supports the soundproof wall panel unit 20 with the soundproof wall panel unit 20 attached with the joint 30.

[0024] The soundproof wall panel unit 20 includes a support 21 fixed to the base 10 and standing vertically, and a sound absorbing panel 22 spanning between adjacent supports 21.

[0025] The pillars 21 support both ends of the sound-absorbing panel 22 in the horizontal direction. As shown in FIG. 1, the pillars 21 are rod-shaped bodies having a U-shaped cross section perpendicular to the longitudinal direction, the cross section being composed of a web 21w and flanges 21f extending from both ends of the web 21w so as to be perpendicular to the web 21w. The adjacent pillars 21 are provided in such a position that the flanges 21f extend in directions facing each other. The pillars 21 support the sound-absorbing panel 22 with the end of the sound-absorbing panel 22 fixed to the flanges 21f. The pillars 21 have fixing holes 21h through which the joints 30 are inserted. The pillars 21 also have locking holes 21a (see FIG. 7) for locking mounting fixtures 43 such as bolts for mounting the protective member 40 to the soundproof wall panel unit 20.

[0026] The sound-absorbing panel 22 is a plate-like body having a sound-absorbing function and a specified size and shape. The sound-absorbing panel 22 is formed from, for example, wood, foamed plastic, glass wool, metal, etc. The sound-absorbing panel 22 is spanned between adjacent pillars 21. The sound-absorbing panel 22 may be attached to the flange 21f of the pillar 21 that is farther from the protective member 40 (the opposite direction to the protruding direction P shown in Figures 2 and 6). There may be a gap between the sound-absorbing panel 22 and the flange 21f of the pillar 21 that is closer to the protective member 40 (in the direction of the protruding direction P). The sound-absorbing panel 22 is located above the mounting portion 42 of the protective member 40.

[0027] The joint 30 is a member for fixing the soundproof wall panel unit 20 to the base 10. The joint 30 is, for example, a bolt and a nut. The joint 30 is passed through a fixing hole 21h provided in the soundproof wall panel unit 20, and is engaged with a locking portion 12a formed on the soundproof wall panel unit mounting portion 12 of the base 10 in a state in which the support 21 of the soundproof wall panel unit 20 is sandwiched between the joint 30 and the soundproof wall panel unit mounting portion 12. The joint 30 protrudes in a protruding direction P from the wall surface of the soundproof wall 100, in this case, the surface of the flange 21f of the support 21. For example, when the wall surface of the soundproof wall 100 is aligned vertically, the joint 30 protrudes in a horizontal direction perpendicular to the wall surface.

[0028] The protective member 40 is attached to the soundproof wall panel unit 20. The protective member 40 is made of, for example, a plated steel sheet or stainless steel.

[0029] The protective member 40 includes a protective plate 41 having an attachment portion 42 for attachment to the soundproof wall 100 and an opening 41a formed at a position away from the joint 30 on an extension of the protruding direction P of the joint 30 protruding from the soundproof wall 100.

[0030] The protective plate 41 is a plate-like body that is aligned along a virtual plane V (see FIG. 7) that is approximately parallel to the wall surface of the soundproof wall 100, here, the surface of the flange 21f of the support 21. Since the protective member 40 includes the protective plate 41, even when piping, electric wires, etc. (hereinafter referred to as "piping, etc. C"; see FIG. 7) are installed close to the soundproof wall 100, the protective member 40 can protect the piping, etc. C from contact with the joints 30. Since the protective member 40 includes the protective plate 41 and the mounting portion 42, each of which has an independent function, the protective member 40 can collectively protect the piping, etc. C from contact with the multiple protruding joints without covering each of the multiple protruding joints. Furthermore, since the protective plate 41 has an opening 41a, even after the protective member 40 is attached to the soundproof wall 100, the soundness of the joints 30, such as the presence or absence of loosening, can be visually confirmed without removing the protective member 40, and repairs such as retightening can be made as necessary.

[0031] The opening 41a may have a shape in which a single opening 41a overlaps with a plurality of joints 30 when viewed in the protruding direction P. For example, as shown in FIG. 7, there may be one opening 41a corresponding to two joints 30.

[0032] The mounting portion 42 has a horizontal portion extending from the upper end of the protective plate 41 toward the soundproof wall panel unit 20, and a vertical portion extending upward from the end of the horizontal portion on the soundproof wall panel unit 20 side. A hole through which the mounting fixture 43 passes is formed in the vertical portion. The mounting fixture 43 passes through the hole and is engaged with the engagement hole 21a.

[0033] As shown in Figs. 1 and 7, the protective member 40 is provided with a pit lid support portion 44 that supports a pit lid L that closes a pit PT (see Fig. 7) along the soundproof wall 100. The pit lid support portion 44 extends, for example, from the upper end of the mounting portion 42 in a direction away from the soundproof wall panel unit 20. With the lower surface of the pit lid L in contact with the upper surface of this pit lid support portion 44, the pit lid support portion 44 supports the load from the pit lid L. In this way, by providing the pit lid support portion 44, the protective member 40 has both the function of protecting the pipes C from contact with the joint 30 and the function of supporting the pit lid L. Therefore, it is possible to omit providing a separate structural member that supports the pit lid L.

[0034] 1, 3 and 7, the protective member 40 has a closing portion 45 that closes the gap e formed between the protective member 40 and the sound-absorbing panel 22 of the soundproof wall 100. The closing portion 45 is a plate-like body that extends from the upper end of the mounting portion 42 toward the sound-absorbing panel 22. The closing portion 45 may extend at an angle upward. This makes it possible to close the gap e formed between the protective member 40 and the sound-absorbing panel 22. This makes it possible to prevent a person's foot from getting caught in the gap e, to suppress the intrusion of rainwater, dust, etc. into the interior of the soundproof wall 100 through the gap e, and to achieve a neat and attractive appearance with few irregularities.

[0035] The protective member 40 is preferably integrally formed by bending a single plate material. This allows the protective member 40 to cover the multiple protruding joints 30 collectively. In addition, the protective member 40 can be integrally formed with the protective plate 41, the mounting portion 42, the pit cover support portion 44, and the blocking portion 45, which have different functions, by press-molding a single plate material. Then, processing to form the opening 41a and the locking hole 21a can be performed before or after press molding. In this way, the protective member 40 has parts with different functions integrally formed by bending a single plate material, so it can be manufactured at a low cost and the construction time can be shortened compared to attaching covers to the multiple protruding joints 30 individually.

[0036] (Construction method) Next, a construction method for the soundproof wall 100 will be described. Fig. 4 is an explanatory diagram showing a base installation step in the construction method for the soundproof wall 100. Fig. 5 is an explanatory diagram showing a soundproof panel installation step in the construction method for the soundproof wall 100. Fig. 6 is an explanatory diagram showing a joint fastening step in the construction method for the soundproof wall 100. Fig. 7 is an explanatory diagram showing a protective member attachment step in the construction method for the soundproof wall 100.

[0037] (1) First, as shown in Fig. 4, the base 10 is laid on the ground surface G or buried in the ground surface G (base installation step). The base 10 is securely fixed to the ground surface G so as to stably resist the weight and overturning moment of the soundproof wall 100. A soundproof wall panel unit mounting portion 12 is provided on a base 11 of the base 10.

[0038] (2) Next, as shown in FIG. 5, the soundproof wall panel unit 20 is arranged so as to surround the soundproof wall panel unit mounting portion 12 of the base 10 (soundproof panel installation process). The soundproof wall panel unit 20 is formed with a fixing hole 21h through which the joint 30 for fixing the base 10 and the soundproof wall panel unit 20 is inserted. The soundproof wall panel unit mounting portion 12 is formed with a locking portion 12a for locking the joint 30 for fixing the base 10 and the soundproof wall panel unit 20. In detail, the soundproof wall panel unit mounting portion 12 is arranged at a position where it is sandwiched between the flanges 21f of the support 21 of the soundproof wall panel unit 20. Note that FIG. 5 shows a case where the soundproof wall panel unit 20 assembled with the support 21 and the sound-absorbing panel 22 is moved from above toward the soundproof wall panel unit mounting portion 12, but is not limited thereto. The support pillars 21 may be attached to the soundproof wall panel unit mounting portion 12, and then the sound absorbing panel may be hung across adjacent support pillars 21. In this case, the support pillars 21 may be moved from the side of the soundproof wall panel unit mounting portion 12, rather than from above it.

[0039] (3) Next, as shown in Fig. 6, the base 10 and the soundproof wall panel unit 20 are fixed together with the joint 30 (joint fastening step). In detail, the joint 30 is passed through a fixing hole 21h formed in the support 21 and engaged with the locking portion 12a of the soundproof wall panel unit mounting portion 12. If the joint 30 is a bolt, it is screwed into the locking portion 12a, which is a female thread. At this time, the joint 30 (if the joint 30 is a bolt, the head of the bolt) protrudes in the protruding direction P.

[0040] (4) Next, as shown in Fig. 7, the protective member 40 is attached to the soundproof wall panel unit 20 (protective member attachment process). In detail, a fastener 43 such as a bolt is passed through a hole formed in the attachment portion 42 of the protective member 40 and engaged with an engagement hole 21a formed in the support 21. In this manner, the protective member 40 can be easily attached to the soundproof wall panel unit 20. Then, the soundproof wall 100 provided with the protective member 40 can be easily constructed.

[0041] (5) After that, the pipes C are laid in the pits PT provided on the outside of the protective member 40 as appropriate.

[0042] (6) Then, after this, one end of the pit lid L that covers the pit PT is appropriately placed on the pit lid support portion 44 of the protection member 40 and supported.

[0043] (7) During inspection, by removing the pit cover L, the joint 30 can be seen through the opening 41a without removing the protective member 40, and repairs can be made as necessary.

[0044] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0045] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
