The present invention relates to a protective member and a soundproof wall.

Conventionally, there have been bolt covers that cover the protruding heads of bolts individually and are fixed to the heads.

Japanese Patent Application Publication No. 10-159500

However, when erecting a soundproof wall above a base fixed to the ground surface and fastening the base to the soundproof wall 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 laying the pipes, etc. on the ground surface after the soundproof wall is constructed.

The present invention was made in consideration of the above-mentioned circumstances, and aims to provide a protective member and soundproof wall that will not damage pipes, etc.

To solve the above problems, the present invention proposes the following:

(1) A protective member according to one embodiment of the present invention comprises an attachment portion to be attached to a soundproof wall, and a protective plate formed to cover a joint protruding from the soundproof wall and having an opening formed in a shape that overlaps with the joint at a position away from the joint on an extension of the protruding direction of the joint.

The protective member of the present invention, which is specified by these characteristics, can protect the pipes, electric wires, etc. from contact with 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 performs its own function independently, so that the pipes, etc. can be collectively protected from contact with multiple protruding joints without covering each of the multiple protruding joints individually. In addition, because the protective plate has an opening, 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.

(2) In the above (1), a pit cover support part may be provided to support a pit cover that closes a pit along the soundproof wall.

The protective member of the present invention, which is characterized by these features, is provided with a pit lid support portion, which serves both to protect the pipes, etc. from contact with the joints and to support the pit lid. This makes it possible to avoid the need to provide a separate structural member to support the pit lid.

(3) In the above (1) or (2), a blocking portion may be provided to block the gap formed between the soundproof wall and the sound-absorbing panel.

The protective member of the present invention, which is specified by these characteristics, can close the gaps that form between the sound-absorbing panel and the sound-absorbing panel. This prevents people's feet from getting caught in the gaps, inhibits the intrusion of rainwater, dust, etc. into the soundproof wall through the gaps, and creates a neat, attractive exterior with few irregularities.

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

The protective member of the present invention, which is characterized by these features, can cover multiple protruding joints collectively. In addition, the protective member can be formed integrally with the protective plate, mounting portion, pit lid support portion, and closing portion, which have different functions, by press molding a single plate material. Then, processing to form the openings and locking holes can be performed before or after press molding. In this way, since the protective member has parts with different functions that are 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 multiple protruding joints.

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

The soundproof wall of the present invention, which is specified by these characteristics, can be easily constructed. It also prevents people's feet from getting caught in gaps in the soundproof wall, inhibits rainwater, dust, etc. from entering the interior of the soundproof wall through the gaps, and produces a soundproof wall with a neat, attractive appearance with few irregularities.

The protective member and soundproof wall of the present invention can prevent damage to pipes, etc.

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 connecting 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.

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.

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

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 that can lock a joint 30 such as a bolt and 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.

The soundproof wall panel unit 20 comprises a vertically extending support 21 fixed to the base 10, and a sound-absorbing panel 22 spanning between adjacent supports 21.

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 with a U-shaped cross section, for example, in a cross section perpendicular to the longitudinal direction, which is 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. 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 ends 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) that lock mounting fixtures 43 such as bolts for attaching the protective member 40 to the soundproof wall panel unit 20.

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 across adjacent supports 21. The sound-absorbing panel 22 may be attached to the flange 21f of the support 21 that is farther from the protective member 40 (opposite 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 support 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.

The joint 30 is a member that fixes 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 with the support 21 of the soundproof wall panel unit 20 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, here, 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 that is perpendicular to the wall surface.

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

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

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. In this way, since the protective member 40 is provided with 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 pipes, etc. C can be protected from contact with the joints 30. And since the protective member 40 is provided with the protective plate 41 and the mounting portion 42, each of which has its own function, it can collectively protect the pipes, etc. C from contact with the protruding joints without covering each of the protruding joints individually. Also, 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.

The opening 41a may be shaped such that a single opening 41a overlaps multiple 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.

The mounting portion 42 has a horizontal portion that extends from the upper end of the protective plate 41 toward the soundproof wall panel unit 20, and a vertical portion that extends 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.

As shown in Figs. 1 and 7, the protective member 40 has a pit cover support portion 44 that supports a pit cover L that closes a pit PT (see Fig. 7) along the soundproof wall 100. The pit cover 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 cover L in contact with the upper surface of this pit cover support portion 44, the pit cover support portion 44 supports the load from the pit cover L. In this way, by having the pit cover support portion 44, the protective member 40 has both the function of protecting the piping C from contact with the joint 30 and the function of supporting the pit cover L. Therefore, it is possible to omit the provision of a separate structural member that supports the pit cover L.

As shown in Figs. 1, 3 and 7, the protective member 40 has a blocking portion 45 that blocks the gap e formed between the sound-absorbing panel 22 of the soundproof wall 100. The blocking 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 blocking portion 45 may extend at an angle upward. This makes it possible to block the gap e formed between the sound-absorbing panel 22 and the protective member 40. 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. from the gap e into the interior of the soundproof wall 100, and to achieve a neat and attractive appearance with few irregularities.

The protective member 40 is preferably integrally formed by bending a single plate material. This allows the protective member 40 to cover multiple protruding joints 30 collectively. In addition, the protective member 40 can be integrally formed with the protective plate 41, mounting portion 42, pit cover support portion 44, and 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 low cost and construction time can be shortened compared to attaching covers individually to multiple protruding joints 30.

(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.

(1) As shown in FIG. 4, first, the base 10 is laid on the ground surface G or buried in the ground surface G (base installation process). The base 10 is securely fixed to the ground surface G so that it can stably resist the weight and overturning moment of the soundproof wall 100. A soundproof wall panel unit mounting portion 12 is provided on the base 11 of the base 10.

(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 has 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 has 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 in a position sandwiched between the flange 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, in which the support 21 and the sound-absorbing panel 22 are assembled, is moved from above toward the soundproof wall panel unit mounting portion 12, but is not limited thereto. The pillars 21 may be attached to the soundproof wall panel unit mounting portion 12, and then the sound-absorbing panels may be placed across the adjacent pillars 21. In this case, the pillars 21 may be moved from the side of the soundproof wall panel unit mounting portion 12, rather than from above it.

(3) Next, as shown in FIG. 6, the base 10 and the soundproof wall panel unit 20 are fixed with the joint 30 (joint fastening process). In detail, the joint 30 is engaged with the locking portion 12a of the soundproof wall panel unit mounting portion 12 through the fixing hole 21h formed in the support 21. 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 (or the head of the bolt, if the joint 30 is a bolt) protrudes in the protruding direction P.

(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.

(5) After this, the pipes C are routed through the pits PT provided on the outside of the protective member 40 as appropriate.

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

(7) When inspecting, 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 if necessary.

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.

In addition, the components in the above embodiment may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above-mentioned modifications may be combined as appropriate.
