Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the configuration disclosed in Patent Document 1, when attaching the above-mentioned fixing bracket, it is necessary to press-fit the fixing bracket into the above-mentioned gap by hitting the fixing bracket from above with a hammer or the like. Therefore, when installing the fixing bracket, a loud noise is generated, which may cause a noise problem if there are houses or the like in the vicinity. In addition, since it takes a corresponding amount of force and time to press-fit the fixing bracket by hitting it with a hammer or the like, it places a burden on the operator.

[0005] The present invention has been made in view of such a background, and an object thereof is to provide an attachment tool for a panel fixing bracket that can prevent the generation of noise during the attachment work of the panel fixing bracket and can reduce the burden on the operator.

Means for Solving the Problems

[0006] One aspect of the present invention is a strut portion formed by arranging a plurality of struts having a U-shaped groove extending in the longitudinal direction so that the grooves face each other; a panel portion including a panel main body and a frame for holding the panel main body, the panel portion being fitted between the grooves facing each other; a fixing fitting having a spring portion formed by bending a metal plate and located inside the gap between the wall surface of the groove and the panel portion to press the panel portion against the strut, and an extension portion extending from the spring portion and located outside the gap; In a panel structure including the above, a mounting tool for a panel fixing fitting used for inserting the spring portion of the fixing fitting into the gap, a tool body having a grippable grip portion; a fixing fitting abutting portion provided at one end of the tool body and having a convex curved shape configured to abut against the extension portion of the fixing fitting; including a panel engaging portion whose tip is engaged with the panel portion and whose base end is rotatably connected to a position between the grip portion and the fixing fitting abutting portion in the tool body, With the panel portion fitted between the grooves facing each other and the spring portion of the fixing fitting applied to the gap, the panel engaging portion is engaged with the panel portion and the fixing fitting abutting portion is abutted against the extension portion, and the tool body is rotated through the grip portion. Thus, with the contact point between the panel engaging portion and the panel portion as the fulcrum, the grip portion as the effort point, and the contact point between the fixing fitting abutting portion and the extension portion as the load point, according to the principle of a lever, the spring portion is configured to be pushed into the gap through the fixing fitting abutting portion. It is a mounting tool for a panel fixing fitting.

[0007] Another aspect of the present invention is a method for attaching a panel fixing fitting using the above-described mounting tool for a panel fixing fitting, The method for attaching the panel fixing fitting is to insert the panel portion into the grooves facing each other, apply the spring portion of the fixing fitting to the gap, engage the panel engaging portion with the panel portion, abut the fixing fitting abutting portion against the extending portion, and rotate the tool body through the gripping portion. By using the principle of a lever with the contact point between the panel engaging portion and the panel portion as the fulcrum, the gripping portion as the effort point, and the contact point between the fixing fitting abutting portion and the extending portion as the load point, the spring portion is pushed into the gap through the fixing fitting abutting portion.

Effect of the Invention

[0008] The attachment tool for the panel fixing fitting of the above aspect can push the spring portion of the fixing fitting into the gap between the wall surface of the groove formed in the support column and the panel portion by the principle of a lever. As a result, there is no need to strike the fixing fitting with a hammer or the like as in the prior art, so the generation of noise can be prevented. In addition, by utilizing the principle of a lever, the spring portion of the fixing fitting can be pushed into the gap with less force and in a shorter time compared to the case of striking with a hammer or the like, and the burden on the operator can be reduced.

[0009] According to the method for attaching the panel fixing fitting of the above other aspect, it is possible to prevent the generation of noise and reduce the burden on the operator when attaching the fixing fitting with the attachment tool for the panel fixing fitting.

[0010] As described above, according to the above aspect, it is possible to provide an attachment tool and an attachment method for a panel fixing fitting that can prevent the generation of noise during the attachment operation of the panel fixing fitting and reduce the burden on the operator.

Mode for Carrying Out the Invention

[0013] The frame body has a first through hole through which a wire for preventing detachment is inserted, and the extending portion has a second through hole at a position overlapping with the first through hole in a state where the fixing fitting is assembled to the panel structure. The panel engaging portion is preferably configured to be engageable with an edge portion of the first through hole in a state of being inserted into the first through hole and the second through hole. In this case, since the fixing fitting can be assembled by using the first through hole and the second through hole through which the wire for preventing detachment is inserted, the attachment of the fixing fitting can be easily performed without changing the conventionally used panel structure at all.

[0014] The convex curved shape in the fixing fitting abutting portion has a shape along the outer peripheral surface of a cylinder or an elliptical cylinder, and the panel engaging portion is preferably configured to be rotatable about the axial direction of the fixing fitting abutting portion. In this case, when attaching the fixing fitting, it becomes easier to rotate the tool body with the fixing fitting abutting portion abutting against the extending portion, and the burden of the attachment work can be further reduced.

[0015] The panel engaging portion can be positioned within the range of the fixing fitting abutting portion in the axial direction of the rotation axis when viewed from a direction perpendicular to the rotation axis of the panel engaging portion. In this case, when the tool body is rotated through the gripping portion, the tip of the panel engaging portion can be strongly engaged with the panel portion, and the workability of attaching the fixing fitting is improved.

[0016] The tip of the panel engaging portion is preferably bent when viewed from a direction parallel to the rotation axis of the panel engaging portion. In this case, the tip of the panel engaging portion can be more strongly engaged with the panel portion, and the workability of attaching the fixing fitting is further improved.

[0017] The panel engaging portion can be positioned outside the range of the fixing bracket abutting portion in the axial direction of the rotation axis when viewed from a direction orthogonal to the rotation axis of the panel engaging portion. In this case, it becomes easier to avoid interference between the tool body and the peripheral members when rotating the tool body, and the workability of attaching the fixing bracket is further improved.

[0018] (Embodiment 1) 1. Mounting Tool 1 for Panel Fixing Bracket Hereinafter, an embodiment of the above-described mounting tool 1 for a panel fixing bracket will be described with reference to FIGS. 1 to 4. In this specification, the mounting tool 1 for a panel fixing bracket is also referred to as the mounting tool 1. As shown in FIG. 1, the mounting tool 1 of the present embodiment is used to insert a spring portion 131 (see FIG. 8) of a fixing bracket 130 into a gap P (see FIG. 10) in a panel structure 100 (see FIG. 5) described later. As shown in FIG. 1, the mounting tool 1 includes a tool body 10, a fixing bracket abutting portion 20, and a panel engaging portion 30. Each configuration will be described in detail below.

[0019] 1-1. Tool Body 10 As shown in FIGS. 1 and 2, the tool body 10 has a substantially rod shape. Let the longitudinal direction of the tool body 10 be X, one of the directions orthogonal to the longitudinal direction X be the width direction Y, and the direction orthogonal to the longitudinal direction X and the width direction Y be the thickness direction Z. The material of the tool body 10 is not particularly limited, but it can be made of metal having sufficient strength. The tool body 10 is preferably hollow in order to reduce weight. For example, a metal water pipe or gas pipe can be used as the tool body 10.

[0020] A region including the central portion of the tool body 10 in the longitudinal direction X forms a gripping portion 11 that can be gripped by an operator. The gripping portion 11 may be subjected to anti-slip processing (not shown). In the present embodiment, the other end 10b, which is the end opposite to one end 10a, which is one end of the tool body 10 in the longitudinal direction X, is formed in a flat spatula shape in the width direction Y.

[0021] 1-2. Fixing Bracket Abutting Portion 20 As shown in FIGS. 1 and 2, the fixture abutting portion 20 is provided at one end 10a in the longitudinal direction X of the tool body 10. The fixture abutting portion 20 has a convex curved shape 21 configured to abut against the extending portion 132 of the fixture 130 as shown in FIG. 13 in the usage state described later. The material of the fixture abutting portion 20 is not particularly limited, but it can be made of metal having sufficient strength. The fixture abutting portion 20 is preferably hollow in order to achieve weight reduction similar to the tool body 10. For example, a metal water pipe or gas pipe can be used as the fixture abutting portion 20. The convex curved shape 21 in the fixture 130 can be a shape along the outer peripheral surface of a cylinder or an elliptical cylinder. In the present embodiment, since the fixture abutting portion 20 is formed by a pipe 20a extending along the width direction Y of the tool body 10, the convex curved shape 21 is a shape along the outer peripheral surface of a cylinder.

[0022] 1-3. Panel engaging portion 30 In the usage state described later, as shown in FIG. 13, the tip 31 of the panel engaging portion 30 is engaged with the panel portion 120 described later. In the present embodiment, as shown in FIG. 1, the tip 31 of the panel engaging portion 30 is bent to form a key shape when viewed from a direction parallel to the rotation axis 30a of the panel engaging portion 30. The base end 32 of the panel engaging portion 30 is rotatably connected to a connection position 10c, which is a position between the gripping portion 11 and the fixture abutting portion 20 in the tool body 10. In the present embodiment, as shown in FIGS. 3 and 4, the base end 32 of the panel engaging portion 30 is rotatably connected to a pair of joint pieces 33 protruding from the connection position 10c of the tool body 10 via a nut 34 and a bolt 35. In the first embodiment, the panel engaging portion 30 is rotatable about a rotation axis 30a, which is the axis of the bolt 35 parallel to the axial direction of the fixture abutting portion 20. The material of the panel engaging portion 30 is not particularly limited, but it can be made of metal having sufficient strength.

[0023] As shown in FIG. 2, by rotating the panel engaging portion 30 to position the tip 31 on the other end 10b side of the tool body 10, the length of the mounting tool 1 in the longitudinal direction X can be shortened, and the portability of the mounting tool 1 can be improved.

[0024] Also, as shown in FIG. 4, the panel engaging portion 30 is located within the range B of the fixing bracket abutting portion 20 in the axial direction (width direction Y) of the rotation axis 30a when viewed from a direction orthogonal to the rotation axis 30a of the panel engaging portion 30.

[0025] 2. Panel structure 100 As shown in FIGS. 5 and 6, the panel structure 100 includes a support column portion 110, a panel portion 120, and a fixing bracket 130 shown in FIGS. 7 and 8. The panel structure 100 is provided on both sides or one side of an automobile road including a highway and constitutes a sound insulation wall or a light shielding wall. In this embodiment, it constitutes a sound insulation wall. Hereinafter, each component of the panel structure 100 will be described in detail.

[0026] 2-1. Support column portion 110 As shown in FIGS. 5 and 6, the support column portion 110 includes a plurality of support columns 111 and 112. The support columns 111 and 112 are long members. In this embodiment, as shown in FIG. 9, H-shaped steel is adopted, and it has groove-shaped sections 111a and 111b in a U-shaped cross-section extending in the longitudinal direction U thereof. Similarly, the support column 112 also has groove-shaped sections 112a and 112b in a U-shaped cross-section. And, as shown in FIG. 6, the support columns 111 and 112 are arranged such that their grooves 111a and 112b face each other. Note that the support column portion 110 may further include those in which support columns similar to the support columns 111 and 112 are arranged in the same manner.

[0027] 2-2. Panel portion 120 As shown in FIG. 5, the panel portion 120 includes a panel body 121 and frame bodies 122, 123, 124, 125, and 126. The panel body 121 is substantially flat and is held by the frame bodies 122 to 126. The structure of the panel body 121 is not limited. For example, it can be made of polycarbonate, metal such as iron or aluminum, resin such as acrylic, etc. In this embodiment, it is a sound insulation panel made of polycarbonate and has a plurality of slit structures. In this embodiment, the width direction of the panel body 121 is S, the thickness direction of the panel body 121 is T, and the height direction of the panel body 121 is U.

[0028] The frame bodies 122 to 126 are made of metal and include an upper outer frame 122, a right outer frame 123, a lower outer frame 124, a left outer frame 125, and a pressing frame 126. By sandwiching the outer edge portion of the panel body 121 between each of the outer frames 122 to 125 and the pressing frame 126, the panel body 121 is held. A packing 127 is interposed between the pressing frame 126 and the panel body 121. Further, first through holes 122a are respectively formed near both ends in the width direction S of the upper outer frame 122.

[0029] 2-3. Fixing fitting 130 As shown in FIG. 8, the fixing fitting 130 is formed by bending a metal plate and has a spring portion 131 and an extending portion 132. The spring portion 131 constitutes a leaf spring and is located inside the gap P between the wall surface of the groove 111a and the panel body 121 as shown in FIG. 15 to press the panel portion 120 against the support column 111. As shown in FIG. 10, in the state before assembly, the width W1 of the lower end portion 131a of the spring portion 131 in the thickness direction T is smaller than the width W0 of the gap P, but the width W2 of the outermost portion 131b of the spring portion 131 is larger than the width W0 of the gap P. Then, as shown in FIG. 15, when the width W2 of the outermost portion 131b is compressed to the width W0 of the gap P, the panel portion 120 is pressed against the support column 111 by the restoring force of the spring portion 131. Note that the support column 112 also has the same configuration to press the panel portion 120 against the support column 112.

[0030] The extending portion 132 is configured to extend from the spring portion 131 and be located outside the gap P as shown in FIG. 15. In the present embodiment, the extending portion 132 extends from the upper end of the spring portion 131 and bends along the upper surface of the upper outer frame 122 in the assembled state. Further, a second through hole 132a is formed in the extending portion 132 at a position overlapping the first through hole 122a of the upper outer frame 122 in the assembled state.

[0031] 3. Method for attaching the panel fixing fitting Next, the method for attaching the panel fixing fitting of the present embodiment will be described. In the method for attaching the panel fixing fitting of the present embodiment, in order to attach the fixing fitting 130 using the attaching tool 1 of the present embodiment, first, as shown in FIG. 10, the panel portion 120 is fitted into the groove 111a of the column 111 and the groove 112b (see FIG. 6) of the column 112 not shown in FIG. 10. Note that the size of the panel portion 120 in the thickness direction T is smaller than the width W3 of the groove 111a. As a result, a gap P is formed between the wall surface of the groove 111a and the panel portion 120 when the panel portion 120 is fitted into the columns 111 and 112.

[0032] Thereafter, as shown by the arrow F1 in FIG. 10, the lower end portion 131a of the fixing fitting 130 is inserted into the gap P, so that, as shown in FIG. 11, the fixing fitting 130 is applied to the gap P. Then, in the direction indicated by the arrow F2, the panel engaging portion 30 of the attaching tool 1 is inserted into the second through hole 132a of the fixing fitting 130 and the first through hole 122a of the upper outer frame 122 in this order, and as shown in FIG. 12, the tip 31 of the panel engaging portion 30 is engaged with the edge portion of the first through hole 122a.

[0033] Next, as shown in FIG. 13, the gripping portion 11 is gripped in the direction indicated by the arrow F3 and the tool body 10 is rotated so as to be lifted up, whereby the fixing fitting abutting portion 20 is brought into contact with the extending portion 132 of the fixing fitting 130. Then, as shown in FIG. 14, the tool body 10 is further rotated so as to be lifted up in the direction indicated by the arrow F4. By the principle of the lever with the contact point between the panel engaging portion 30 and the panel portion 120 as the fulcrum Q1, the gripping portion 11 as the effort point Q2, and the contact point between the fixing fitting abutting portion 20 and the extending portion 132 as the action point Q3, the fixing fitting abutting portion 20 presses the extending portion 132 downward, and the spring portion 131 is pushed into the gap P. Then, the spring portion 131 is compressed by being pushed into the gap P.

[0034] Further, by rotating the gripping portion 11 so as to fall in the direction indicated by the arrow F5 in FIG. 15, the extending portion 132 is further pressed downward until the extending portion 132 abuts against the upper outer frame 122, and the spring portion 131 is further pushed into the gap P. As a result, the spring portion 131 will be located inside the gap P. Also, the second through-hole 132a will overlap with the first through-hole 122a. Thereby, the attachment of the fixing fitting 130 is completed. After that, as shown in FIG. 16, a wire 140 is inserted through the first through-hole 122a and the second through-hole 132a, and the fixing fitting 130 is covered with a cover (not shown), and the panel structure 100 is completed.

[0035] 4. Operational Effects Next, the operational effects of the attachment tool 1 of the present embodiment will be described in detail. The attachment tool 1 of the present embodiment can push the spring portion 131 of the fixing fitting 130 into the gap P between the wall surfaces of the grooves 111a and 112a formed in the columns 111 and 112 and the panel portion 120 by the lever principle. As a result, there is no need to strike the fixing fitting 130 with a hammer or the like as in the prior art, so that the generation of noise can be prevented. Also, by utilizing the lever principle, the spring portion 131 of the fixing fitting 130 can be pushed into the gap P with less force and in a shorter time compared to the case of striking with a hammer or the like, and the burden on the operator can be reduced.

[0036] Further, in the first embodiment, the upper outer frame 122 has a first through-hole 122a through which the anti-drop wire 140 is inserted, and the extending portion 132 has a second through-hole 132a at a position overlapping the first through-hole 122a in a state where the fixing fitting 130 is assembled to the panel structure 100. Then, the panel engaging portion 30 is engaged with the edge of the first through-hole 122a in a state of being inserted through the first through-hole 122a and the second through-hole 132a. Thereby, since the fixing fitting 130 can be assembled using the first through-hole 122a and the second through-hole 132a through which the anti-drop wire 140 is inserted, the fixing fitting 130 can be easily attached without changing the conventionally used panel structure 100 at all.

[0037] In addition, in the first embodiment, the outer peripheral surface of the fixture abutting portion 20 has a shape along the outer peripheral surface of a cylinder, and the panel engaging portion 30 is configured to be rotatable about a rotation axis 30a parallel to the axial direction of the fixture abutting portion 20. Thereby, when attaching the fixture 130, it becomes easier to rotate the tool body 10 with the fixture abutting portion 20 abutting against the extending portion 132, and the burden of the attachment work can be further reduced.

[0038] In addition, in the first embodiment, the panel engaging portion 30 is located within a range B of the fixture abutting portion 20 in the axial direction (width direction Y) of the rotation axis 30a when viewed from a direction orthogonal to the rotation axis 30a of the panel engaging portion 30. Thereby, when rotating the tool body 10 via the gripping portion 11, the tip 31 of the panel engaging portion 30 can be strongly engaged with the panel portion 120, and the workability of attaching the fixture 130 is improved.

[0039] In addition, in the first embodiment, the tip 31 of the panel engaging portion 30 is bent when viewed from a direction parallel to the rotation axis 30a of the panel engaging portion 30. Thereby, the tip 31 of the panel engaging portion 30 can be more strongly engaged with the panel portion 120, and the workability of attaching the fixture 130 is further improved.

[0040] In addition, according to the method for attaching the panel fixture of the present embodiment, it is possible to prevent the generation of noise and reduce the burden on the operator when attaching the fixture 130 with the attachment tool 1.

[0041] As described above, according to the above aspect, it is possible to provide an attachment tool 1 and an attachment method for a panel fixture that can prevent the generation of noise during the attachment work of the fixture 130 to the panel portion 120 and reduce the burden on the operator.

[0042] (Second Embodiment) In the above-described Embodiment 1, the convex curved shape 21 in the fixing fitting abutting portion 20 is formed along the outer peripheral surface of a cylinder. However, in the present Embodiment 2, as shown in FIG. 17, the convex curved shape 21 in the fixing fitting abutting portion 20 is formed along the outer peripheral surface of an elliptical cylinder. In the present Embodiment 2, the same components as those in the above-described Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted.

[0043] The usage mode of the attachment tool 1 in the present Embodiment 2 is the same as that in the above-described Embodiment 1. As shown in FIG. 18, the panel engaging portion 30 of the attachment tool 1 is inserted into the second through hole 132a of the fixing fitting 130 and the first through hole 122a of the upper outer frame 122 in this order, and the tip 31 of the panel engaging portion 30 is engaged with the edge of the first through hole 122a. Then, as shown in FIG. 19, the tool body 10 is rotated in the direction indicated by the arrow F3 to bring the convex curved shape 21 of the fixing fitting abutting portion 20 into contact with the extending portion 132 of the fixing fitting 130.

[0044] Thereafter, as shown in FIG. 20, the tool body 10 is further rotated in the direction indicated by the arrow F4. Similar to the case of Embodiment 1, the extending portion 132 is pressed downward through the fixing fitting abutting portion 20 to push the spring portion 131 into the gap P. Then, as shown in FIG. 21, further, by rotating the tool body 10 in the direction indicated by the arrow F5, the extending portion 132 is pressed downward until the extending portion 132 contacts the upper outer frame 122, and the spring portion 131 is further pushed into the gap P. As a result, the spring portion 131 is positioned inside the gap P.

[0045] According to the present Embodiment 2, since the convex curved shape 21 in the fixing fitting abutting portion 20 is formed along the outer peripheral surface of an elliptical cylinder, the rotation angle of the tool body 10 required to push the spring portion 131 into the gap P can be made smaller than in the case of Embodiment 1 where the convex curved shape 21 is formed along the outer peripheral surface of a cylinder. Note that the present Embodiment 2 also has the same operational effects as those in the case of Embodiment 1.

[0046] (Embodiment 3) In the above-described Embodiment 1, as shown in FIG. 4, the panel engaging portion 30 was positioned within the range A of the fixture abutting portion 20 in the axial direction of the rotation axis 30a when viewed from a direction perpendicular to the rotation axis 30a of the panel engaging portion 30. In contrast, in this Embodiment 3, as shown in FIG. 22, the panel engaging portion 30 is positioned outside the range A of the fixture abutting portion 20 in the axial direction of the rotation axis 30a when viewed from a direction perpendicular to the rotation axis 30a of the panel engaging portion 30. That is, when the mounting tool 1 is viewed from above in the thickness direction Z, the panel engaging portion 30 is located at a position shifted in the width direction Y from the fixture abutting portion 20 and does not overlap with the fixture abutting portion 20.

[0047] In this Embodiment 3, as shown in FIGS. 22 and 23, the panel engaging portion 30 is rotatably connected to one L-shaped joint piece 33 protruding from the connection position 10c via a pair of nuts 34 and bolts 35. Also in this Embodiment 3, similar to the case of Embodiment 1, the panel engaging portion 30 is rotatable about a rotation axis 30a parallel to the axial direction of the fixture abutting portion 20. On the other hand, the tip 31 of the panel engaging portion 30 has a key shape bent away from the tool body 10 in the width direction Y.

[0048] The usage mode of the mounting tool 1 in this Embodiment 3 is the same as that of the above-described Embodiment 1. As shown in FIG. 24, the panel engaging portion 30 of the mounting tool 1 is inserted in the order of the second through-hole 132a of the fixture 130 and the first through-hole 122a of the upper outer frame 122 in the direction indicated by the arrow F2. Then, as shown in FIG. 25, the tip 31 of the panel engaging portion 30 is engaged with the edge of the first through-hole 122a on the back side of the paper surface. Then, as shown in FIG. 26, the tool body 10 is rotated in the direction indicated by the arrow F3 to bring the convex curved shape 21 of the fixture abutting portion 20 into contact with the extended portion 132 of the fixture 130.

[0049] Thereafter, as shown in FIG. 27, the tool body 10 is further rotated in the direction indicated by the arrow F4, and in the same manner as in the case of the first embodiment, the extended portion 132 is pressed downward via the fixture abutting portion 20, and the spring portion 131 is pushed into the gap P. Then, as shown in FIG. 28, further, by rotating the tool body 10 in the direction indicated by the arrow F5, the extended portion 132 is pressed downward until the extended portion 132 abuts against the upper outer frame 122, and the spring portion 131 is further pushed into the gap P. As a result, the spring portion 131 comes to be positioned inside the gap P.

[0050] According to the third embodiment, since the panel engaging portion 30 is located outside the range A of the fixture abutting portion 20 in the axial direction of the rotation shaft 30a when viewed from the direction orthogonal to the rotation shaft 30a, it becomes easier to avoid the tool body 10 interfering with the peripheral members when the tool body 10 is rotated, and the workability of attaching the fixture 130 is further improved. Also, in the third embodiment, the same operational effects as those in the case of the first embodiment are exhibited. Note that the convex curved shape 21 of the fixture abutting portion 20 in the third embodiment may be a shape along the outer peripheral surface of an elliptical cylinder as in the second embodiment.

[0051] Also, in the configurations of the first to third embodiments, the convex curved shape 21 of the fixture abutting portion 20 may be a shape along a spherical surface. Further, together with this, in the configurations of the first to third embodiments, the connection mechanism of the proximal end 32 of the panel engaging portion 30 may be configured by a universal joint that can rotate in a desired direction.

[0052] The present invention is not limited to the above-described embodiments, and can be applied to various embodiments without departing from the gist thereof.
