Description

The present invention relates to a soundproof panel installation structure that uses fastening members to attach soundproof panels to posts.

The configuration of attaching soundproofing panels to erected supports using fastening members such as bolts and nuts has been used for some time, and related inventions have been published.

For example, Patent Document 1 describes a soundproof wall construction method in which a framed soundproof panel is constructed by attaching a peripheral frame material as a reinforcing member to the periphery of a synthetic resin soundproof board, and mounting holes are drilled through the mounting portion of the peripheral frame material at at least four corners of the soundproof panel. Mounting bolts are also pre-installed and fixed upright in positions corresponding to the mounting holes on the mounting surface of the panel to the soundproof wall support posts. At the construction site, the mounting bolts are fitted into the mounting holes to hang the soundproof panel on the support posts, and then the panel is fastened in place with nuts.

Japanese Patent Application Publication No. 6-33425

The soundproof wall construction method disclosed in Patent Document 1 simplifies the installation of soundproof panels by fastening mounting bolts to the posts in advance, but there is a problem in that it is difficult to fasten mounting bolts to posts that are already erected.

The present invention provides a soundproof panel installation structure that allows fastening members for installing soundproof panels to be easily attached to upright supports.

In order to achieve the above object, the present invention has the following configuration.
In other words, the installation structure for a soundproof panel according to the present invention is an installation structure for a soundproof panel in which a soundproof panel is installed on a support pillar using a fastening member having a male threaded member and a female threaded member , the soundproof panel being fixed to the support pillar via an attachment member attached to the soundproof panel, the support pillar being formed with a through hole through which the head of the male threaded member can be inserted so as to pass in the front-to-rear direction, a washer member having a washer portion being arranged behind the through hole, an insertion portion through which the head can be inserted and an engaging portion which is connected to the insertion portion and through which the head cannot be inserted are formed so as to pass through the flat washer portion in the front-to-rear direction , the fastening member being characterized in that the head of the male threaded member is arranged behind the washer member and engaged with the engaging portion, the male threaded portion of the male threaded member being inserted into the through hole formed in the support pillar and the through hole formed in the attachment member and is threadedly connected to the female threaded member in front of the support pillar.

According to the installation structure of the soundproof panel of the present invention, a through hole into which the head of the male screw member of the fastening member can be inserted is formed so as to pass through the support in the front-to-rear direction, so that the head of the male screw member can be inserted into the through hole from the front side and easily attached to the support.
In addition, a washer member having an insertion portion through which the head of the male screw member can be inserted and an engagement portion connected to this insertion portion through which the head cannot be inserted is positioned behind the through hole.Therefore, by inserting the head of the male screw member inserted from the front side of the support into the insertion portion of the washer member and positioning the engagement portion at the position of the head, the male screw member can be placed in an engaged state and prevented from slipping out forward.
In addition, the head of the male screw member is positioned behind the washer member and engaged with the engaging portion, and the male screw portion of the male screw member is inserted through the mounting member of the soundproof panel and the through hole and screwed into the female screw member in front of the support, so that the soundproof panel can be attached to the support and installed using the male screw member engaged with the washer member.

It is preferable if the washer member has a flat washer portion and the insertion portion and the engagement portion are formed as holes or notches that pass through the washer portion, as this makes it easier to insert the head of the male screw member into the insertion portion of the washer portion behind the through hole.

Furthermore, if a hard lock nut is used for the female threaded member and threadedly connected to the male threaded member at the front of the support, the hard lock nut can be easily tightened and loosening with use can be prevented.

Furthermore, if the support pillar is made of H-shaped steel and the ends of soundproofing members formed separately from the soundproofing panels are inserted between the flanges of the H-shaped steel, the soundproofing panels and soundproofing members will be arranged front to back, improving the soundproofing effect. Furthermore, since the male screw member can be inserted from the front into the through-hole formed in the front flange of the H-shaped steel, the soundproofing members are less likely to interfere with the installation of the soundproofing panels, and the soundproofing panels can be easily attached to the support pillars.

The soundproof panel installation structure of the present invention allows fastening members for installing soundproof panels to be easily attached to upright supports.

FIG. 2 is a front view showing the soundproof panel of FIG. 1. FIG. 14 is a diagram showing an outline of the right side of FIG. 13 .

The embodiments of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a front view showing an embodiment of an installation structure for a soundproof panel 1 according to the present invention, and FIG. 2 is a cross-sectional view taken along the line AA in FIG.
In the following description, the up-down direction in FIG. 1 will be referred to as the up-down direction, the left-right direction in FIG. 1 that is perpendicular to the up-down direction will be referred to as the horizontal direction, and the left-right direction in FIG. 2 that is perpendicular to both the up-down direction and the left-right direction will be referred to as the front-rear direction.
In the drawing, reference numeral 2 denotes a support.
The two support columns 2 shown in FIGS. 1 and 2 are arranged in a horizontal direction with a gap between them.
Each support column 2 is formed of an H-shaped steel having flanges 21a and 21b at both ends of a web 22, and the flanges 21a and 21b are disposed on the front and rear sides, respectively.

Soundproofing members 9 are installed between the pillars 2.
The soundproofing member 9 is a concrete plate-like body that functions as a soundproofing board, and is attached by inserting both left and right ends in the horizontal direction between the flanges 21 a and 21 b of each of the support posts 2 .
A biasing member (not shown) made of an elastic material such as synthetic rubber is attached between the flange 21a of the support 2 and the soundproofing member 9. This biasing member biases the soundproofing member 9 rearward, pressing the rear surface of the soundproofing member 9 against the flange 21b.

Soundproof panels 1 are installed between the pillars 2.
The soundproof panel 1 is a sound-absorbing panel with a sound-absorbing material (not shown) inside, and is disposed in front of the soundproof member 9 .
Specifically, long mounting members 3 are installed between the pillars 2, and the upper and lower ends of the soundproof panel 1 are attached to each of the two mounting members 2 installed at a distance in the vertical direction, thereby installing the soundproof panel 1.

Each of the mounting members 3 has its longitudinal end fixed to the support 2 by a fastening member 5 that passes through a flange 21 of the support 2 .
The fastening member 5 has a male threaded member 51 and a female threaded member 52, and the male threaded member 51 is a hexagonal bolt having a male threaded portion 51b and a head portion 51a having a diameter larger than that of the male threaded portion 51b.
The male screw member 51 is attached to the support 2 with the male screw portion 51b inserted through the flange 21a and the washer member 4 positioned behind it, and the head portion 51a positioned behind the washer member 4.
Each mounting member 3 is attached to the support 2 by inserting the male thread portion 51 b of this male thread member 51 into the end of the mounting member 3 and screwing in the female thread member 52 .

FIG. 3 shows a washer member 4 used to attach the mounting member 3 of FIGS. 1 and 2, where (A) is a front view and (B) is a side view.
The washer member 4 is a rectangular metal plate, and has a flat washer portion 41 formed with a hole-shaped insertion portion 42 and an engagement portion 43 that penetrate the washer portion 41 in the front-rear direction.
The insertion portion 42 is a substantially circular through-hole, and is formed to a size that allows the head portion 51a of the male screw member 51 to pass through inside thereof.
The engaging portion 43 is a substantially elongated through-hole that extends upward from the top of the insertion portion 42, and is formed to be narrower than the insertion portion 42. Specifically, the engaging portion 43 is formed to have a size that allows the male thread portion 51b of the male thread member 51 to pass through its inside, but does not allow the head portion 51a to pass through.
In other words, a so-called potbelly-shaped through hole is formed in the washer portion 41 of the washer member 4, and the wide circular hole-shaped portion located at the bottom constitutes the insertion portion 42, and the narrow elongated hole-shaped portion located at the top constitutes the engagement portion 43.

4 is a front view showing the state in which the washer member 4 of FIG. 3 is disposed behind the through-hole 24 of the support 2, and FIG. 5 is a cross-sectional view taken along the line AA of FIG.
The support 2 has a circular through-hole 24 that penetrates the flange 21a, and the through-hole 24 is formed in a circular shape with a diameter that is approximately the same as the diameter of the insertion portion 42 of the washer member 4. In other words, the inside of the through-hole 24 is formed to a size that allows the head 51a of the male screw member 51 to pass through.
The washer member 4 shown in Figures 4 and 5 has the plate surface of the washer portion 41 abutting against the rear surface of the flange 21 located inside the support 2, and the insertion portion 42 positioned at a position corresponding to the through hole 24.

With respect to the support post 2 and washer member 4 shown in FIGS. 4 and 5, the head 51a of the male screw member 51 of the fastening member 5 can be inserted from the front side and passed through the through hole 24 and the insertion portion 42.
As shown in particular in Figure 5, the distance between the rear surface of the flange 21 of the support 2 and the soundproofing member 9 located behind it is set to be smaller than the length of the male thread portion 51b of the male thread member 51 shown in Figure 5. In this way, if there is not a sufficiently large gap behind the through hole 24 formed in the support 2, it is difficult to insert the male thread portion 51b of the male thread member 51 into the through hole 24 from behind, but by making the head 51a of the male thread member 51 insertable from the front side of the support 2 as shown in Figures 4 and 5, the operation of inserting the male thread member 51 is made easier.

After the head 51a of the male screw member 51 inserted from the front of the support 2 is passed through the through hole 24 and the inside of the insertion portion 42 shown in Figures 4 and 5, the washer member 4 is moved downward to allow the male screw portion 51b to enter the engagement portion 43, thereby bringing the washer member 4 and the male screw member 51 into an engaged state.
FIG. 6 is a view showing the washer member 4 and the male screw member 51 of FIG. 5 in an engaged state, and FIG. 7 is a front view of FIG.
The male threaded member 51 shown in Figures 6 and 7 has its male threaded portion 51b positioned inside the engaging portion 43 of the washer member 4, so that the head 51a abuts against the washer portion 41, restricting forward movement.
Furthermore, the male screw portion 51 b of the male screw member 51 is inserted into the through-hole 24 of the support 2 , so that its movement in the vertical and horizontal directions is restricted to the inside of the through-hole 24 .
Furthermore, since the gap behind the through hole 24 of the male screw member 51 is smaller than the male screw portion 51b, rearward movement is also restricted to the inside of the gap.
In this way, by inserting the male thread portion 51b into the engaging portion 43 of the washer member 4 and establishing an engaged state, the movement of the male thread member 51, particularly including forward movement out of the through hole 24, can be effectively restricted.

As shown in Figures 6 and 7, when the washer member 4 and the male screw member 51 are engaged, more than half of the plate-shaped washer portion 41 is positioned below the male screw portion 51a, so the washer member 4 rotates under its own weight, turning upside down, and positioning the insertion portion 42 at the position of the male screw member 51, preventing the engagement with the male screw member 51 from being released.
Furthermore, as shown in Figures 6 and 7, when the washer member 4 and the male screw member 51 are engaged, the male screw portion 51b is sandwiched between the upper edge of the engagement portion 43 of the washer member 4, which is moving downward due to its own weight, and the lower edge of the through hole 24, so that the male screw member 51 is caught on the support 2 and the washer member 4, preventing it from falling off.This is expected to have the effect of creating a so-called temporary fastening state in which the male screw member 51 and the washer member 4 will not fall off the support 2 even if the worker lets go of them.
6 and 7, the washer member 4 is formed so that the web 22 of the support 2 is located laterally adjacent to the washer portion 41. The washer portion 41 and the web 22 come into contact with each other, preventing the washer member 4 from rotating, and the insertion portion 42 is positioned at the position of the male screw member 51, preventing problems such as disengagement from the male screw member 51.

Fig. 8 is a front view showing the mounting member 3 shown in Figs. 1 and 2, Fig. 9 is an enlarged view of a portion of Fig. 8, and Fig. 10 is a left side view of Fig. 8. Fig. 9 is an enlarged view of the left end portion of the mounting member 3 in Fig. 8.
The mounting member 3 is an elongated body with an L-shaped cross section whose longitudinal direction faces the horizontal direction, and is specifically formed from an L-shaped steel.
The mounting member 3 has two approximately flat plate-like portions arranged vertically, and the plate-like portion arranged like a vertical wall extending in the vertical direction is used as the mounting portion 31, and is used for mounting to the support 2 or the soundproof panel 1.
Furthermore, a plate-like portion arranged like a side wall extending forward from the mounting portion 31 serves as a reinforcing portion 32, which increases the overall rigidity of the mounting member 3.
Two elongated through holes 34 are formed at each of the longitudinal ends of the mounting portion 31. Each through hole 34 is formed to a size that allows the male thread portion 51 a of the male thread member 51 to be inserted therethrough, and is used for mounting to the support 2.
Additionally, three forward-projecting male threaded portions 33 are formed at intervals in the horizontal direction on the mounting portion 31. Each male threaded portion 33 is formed by inserting the male threaded portion of a hexagonal bolt from the rear of the mounting portion 31, and the head of each hexagonal bolt is fixed to the rear surface of the mounting portion 31 by welding.

11 is a front view showing the state in which the mounting member 3 of FIG. 8 is mounted on the support pole 2, and FIG. 12 is a cross-sectional view taken along the line AA of FIG.
11, two mounting members 3 of FIG. 8 are arranged vertically with a gap between them, and both longitudinal ends of each mounting member 3 are fixed to the support 2. Of the mounting members 3 shown in FIG. 11, the upper mounting member 3 is oriented so that the reinforcing portion 32 is located above the mounting portion 31, and the lower mounting member 3 is oriented so that the reinforcing portion 32 is located below the mounting portion 31.

The mounting member 3 shown in FIG. 12 is fixed to the support 2 by inserting the male thread portion 51a of the male thread member 51 shown in FIG. 6 into the inside of the through-hole 34 and screwing in the female thread member 52.
The mounting member 3 has its rear surface abutted against the front surface positioned outside the flange 21 a of the support 2 and is fixed by the fastening member 5 .

The female threaded member 52 of the fastening member that fixes the mounting member 3 to the support 2 is a so-called hard lock nut in which a pair of nut members are screwed onto a male thread. After screwing the first nut member onto the male threaded portion 51a with an appropriate torque, the second nut member is similarly screwed onto the male threaded portion 51a with an appropriate torque, thereby effectively preventing loosening from the male threaded portion 51a.
In this way, the task of tightening multiple nut members in order with the appropriate torque is difficult with a configuration in which the female screw member 52 is positioned behind the through hole 24 through which the male screw portion 51a is inserted. However, by arranging the head 51a of the male screw member 51 so that it can be inserted from the front side of the support 2 and arranging the male screw portion 51b so that it protrudes forward from the support 2, the female screw member 52 can be positioned in front of the support, making it easier to screw it in.
Furthermore, the washer member 4 arranged behind the through hole 24 has the web 22 of the support 2 located laterally near the washer portion 41, so even if rotation is transmitted to the washer member 4 during the tightening operation of the female screw member 52, problems such as the washer portion 41 abutting against the web 22 and causing the washer member 4 to rotate can be prevented.
11 is attached to the support 2 in the same manner as the left end shown in FIG. 12, and both ends of the lower mounting member 3 shown in FIG. 11 are attached to the support 2 in the same manner as the configuration shown in FIG. 12, except that the reinforcing portion 32 is positioned below the mounting portion 31.

FIG. 13 is a front view showing the soundproof panel 1 of FIG. 1, and FIG. 14 is a diagram showing an outline of the right side of FIG.
The soundproof panel 1 is formed in the shape of a rectangular box, and a sound absorbing material is installed in the hollow portion inside the box.
Specifically, the frame body is formed by connecting the ends of two elongated horizontal frames 11 spaced apart in the vertical direction and two elongated vertical frames 12 spaced apart in the horizontal direction on the left and right.
In addition, a rectangular front panel 15 and a rectangular rear panel are attached to the front and rear sides of this frame body with a gap between them, and the sound-absorbing material is placed between the front panel 15 and the rear panel to form a rectangular box-shaped soundproof panel 1.
The front panel 15 has a large number of circular through-holes formed all over its surface, which function to allow noise from the front side to pass through these through-holes and reach the sound-absorbing material installed inside, where it is attenuated.
The rear panel also functions as a sound insulating panel.
13 and 1, only a portion of the circular through-holes formed in the front plate 15 are shown to simplify the drawings.

The soundproof panel 1 is formed with a mounting plate portion 13 to be attached to the mounting member 3 .
The mounting plate portions 13 are provided in the shape of rectangular plates, and three of them are formed on each of the horizontal frames 11, making a total of six.
Specifically, each mounting plate portion 13 is positioned near the rear surface of the soundproof panel 1 and is formed so as to protrude upward from the top of the upper horizontal frame 11 and so as to protrude downward from the bottom of the lower horizontal frame 11.
Each mounting plate portion 13 has one elongated through hole 14 formed therein that penetrates in the front-to-rear direction, and each through hole 14 is sized so that the male thread portion 33 of the mounting member 3 can be inserted therethrough.
Each mounting plate 13 is bent so that a portion thereof protrudes forward, and this protruding portion is attached to the horizontal frame 11 with fastening members consisting of bolts and nuts 16. Each mounting plate 13 is provided so that its mounting position in the longitudinal direction of the horizontal frame 11 can be adjusted.

In the soundproof panel 1 shown in FIG. 13, the through holes 14 of the mounting plate portions 13 are arranged at positions corresponding to the male thread portions 33 of the mounting members 3 shown in FIG.
The soundproof panel 1 is attached to the mounting members 3 by inserting the male threaded portions 33 into the through holes 14 and screwing nuts, and is installed between the posts 2 as shown in Figure 1.

The installation structure of the soundproof panel 1 according to the present invention is not limited to the above embodiment, and various modifications are possible within the scope of the gist of the present invention.
For example, in the installation structure of the soundproof panel 1 shown in Figures 1 and 2, the mounting member 3 to be attached to the support 2 and the soundproof panel 1 are formed separately, but this is not limited to this. The mounting member 3 and the soundproof panel 1 may be formed integrally, or a part of the soundproof panel 1 may be used as the mounting member 3 and a through hole or the like may be formed in that part for attaching the male thread portion 51b of the fastening member 5.

Furthermore, the soundproof panel 1 is provided on a sound-absorbing panel with sound-absorbing material on the inside, but this is not limited to this and it may also be a soundproof panel without sound-absorbing material.

Furthermore, in the installation structure of the soundproof panel 1, the soundproofing member 9 is placed behind the soundproof panel 1 and is installed between each support pillar 2, but this is not limited to this, and the soundproofing member 9 does not have to be present.

Furthermore, in the installation structure for the soundproof panel 1, a hard lock nut is used for the female threaded member 52 of the fastening member 5, but this is not limited to this, and other members having a female threaded portion that can be threaded into the male threaded portion 51b of the male threaded member 51 may also be used.

Furthermore, the washer member 4 has the insertion portion 42 and engagement portion 43 formed as through-holes in the washer portion 41, but this is not limited to this. The insertion portion 42 and engagement portion 43 may also be formed as notches so that part of them connects to the edge of the washer portion 41.
