Description

[0001]
BACKGROUND OF THE INVENTION
The present invention mainly relates to a mounting structure and a mounting bracket for mounting adherends such as panels and block products on structures along railway lines such as highways and railways, for prevention measures such as noise and radio wave interference, or for beautification. It is about.
[0002]
[Prior art]
Conventionally, as this type of panel structure, for example, when installing panel products such as soundproof walls, tunnel interior boards, girder decoration boards, or radio wave absorption panels installed on structures such as ordinary roads and highways, the structure is previously set. The panel product was pressed against the base drum edge fixed to the body, the mounting hole position of the panel product was aligned with the hole position formed in the base drum edge, and the bolt was screwed in and tightened strongly. Another method is to fix the panel by screwing a self-drilling drill screw into an appropriate position where the panel and the base drum edge overlap in the field without drilling the base drum edge, for example. Has been adopted.
[0003]
[Problems to be solved by the invention]
However, since the former is strongly fastened and fixed by bolts, high reliability can be obtained in terms of safety even when external force such as vibration or wind load is applied, but if there are slight unevenness or deformation of the ground, or obstacles etc. Since the hole position is shifted, a detailed layout design corresponding to the hole position is required in advance. Therefore, a lot of labor and cost are involved in the field survey and its design work. In addition, it is designed with high accuracy, and even if drilling is performed on the base cylinder edge based on the design, the hole position between the base cylinder edge and the panel may not match, so drilling by field matching The work to apply is inevitable.
[0004]
In the latter case, it is preferable in terms of being able to perform a screwing treatment at a suitable position at the time of construction and flexible construction, but because the fastening strength of the drill screw is weak or there is a possibility that a large variation in fastening strength may occur. There are serious problems such as lack of reliability in terms of safety.
[0005]
According to the description of Japanese Patent Application Laid-Open No. 2000-96522 as a means for solving these problems, a plurality of mounting grooves with an opening edge projecting inward are provided on the back side of the panel in the longitudinal direction, and the structure, etc. The mounting bolt head for mounting to the mounting groove is slidably and non-rotatably mounted in the mounting groove, and is screwed by matching the bolt hole position of the structure by arbitrarily sliding the mounting groove bolt. Such a method has been proposed. However, the mounting groove attached to the back of the panel is generally made of an aluminum extruded mold, and the larger the panel, the greater the amount of use, so that the cost of expensive components increases and the product cost increases. The problem comes up.
[0006]
Therefore, the present invention has an inexpensive structure in which the mounting bolt position of an adherend such as a panel can be appropriately adjusted two-dimensionally, can be easily attached to a roadside structure such as a road or a railway, and is safe. It is intended to provide a highly flexible and versatile adherend mounting structure and mounting bracket.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be specifically described with reference to the drawings.
[0016]
FIG. 1 is a partially cutaway perspective view showing an embodiment in which a connecting member is attached to a panel according to the present invention, and FIG. 2 is an enlarged perspective view of the connecting member of FIG. 3 is a perspective view of the main part of the panel of FIG. 1 attached to the structure, and FIG. 4 is a partial sectional view of the attachment of FIG. FIG. 5 is an installation view showing an embodiment in which the radio wave absorption panel of the present invention is installed in a structure.
[0017]
First, FIG. 1 to FIG. 4 will be described in more detail. As shown in FIGS. 1 and 2, the panel 1 includes a back plate 12 a of a housing 12 that encloses a radio wave absorbing material 11, and two opposite sides are bent into a substantially 7-letter shape to form a rail 12 b. The electromagnetic wave absorbing panel is provided with at least four connecting members 2 slidably attached to rails 12b of the panel. The connecting member 2 includes an engaging portion 21 that is slidable by complementing the inside of the rail 12 b, and a fastening surface 22 that extends from the engaging portion 21 and is flush with the back plate 12 a of the panel 1. The guide groove 22a is formed in the tightening surface 22, and 23 bolts can be inserted through the tightening surface 22 so as not to rotate. And fixing means 22b, such as stamping deformation of the guide groove peripheral part of 23 bolts inserted, is given, and it is fixing so that a bolt head may not fall out.
[0018]
Since the connecting member 1 is formed of an aluminum extrusion mold material and can be used after being cut to a required length, it can be provided at a low cost, and it is easy to attach a bolt and withstands a desired tightening strength. It is done. Since the guide groove 22a is formed so that the head of the bolt 23 is slidable, both ends of the guide groove may have a retaining structure, and the bolt may be slidably engaged therebetween. Since it slides in the same direction as the rail 12b, there is no meaning to move, and it is preferable that it is fixed in terms of workability.
[0019]
In FIG. 3, mounting bars 33 made of an aluminum mold are formed on each surface of the mounting bar below the support member 32 attached to the main body 31 attached to the structure 3 such as a road or a railroad. The first sliding groove 33a is screwed and attached horizontally. Further, the rail 12b of the panel 1 is arranged so as to cross the mounting bar further below the mounting bar 33, and the bolt 23 of the connecting member 21 engaged with the rail on the back side of the panel is connected to the mounting bar. The second sliding groove 33 b of 33 is slidably attached via a metal fitting 34.
[0020]
In this way, a plurality of panels 1 are continuously joined to form a wide area so that the rails 12b on the back side of the panel are adjacent to each other. The panel 1 is provided with a wire 35 penetrating the side surface of the rail, and measures to prevent the panel from dropping are taken.
[0021]
As shown in FIG. 4, the mounting structure of the panel 1 attached as described above includes the back plate 12a in which the radio wave absorber 11 is covered with the front plate 12c and the rails 12b are formed at both end edges. A screw 13 is superposed on the face plate 12c to form a radio wave absorption panel, and the engaging portion 21 of the connecting member 2 is inserted into the rail 12b and slidably attached, and also intersects the traveling direction of the rail 12b. A mounting bar 33 is disposed in the direction of the bolt, and a bolt 23 erected on the fastening surface 22 of the connecting member 2 on a metal fitting 34 slidably mounted in a second guide groove 33b formed in the mounting bar. Is made to be screwed.
[0022]
Accordingly, the metal fitting 34 that slides in the second guide groove 33b formed in the mounting bar 33 and the connecting member 2 that slides by engaging with the rail 12b can move individually in the X-axis and Y-axis directions. Therefore, even if the joining position of the mounting bar 33 and the panel 1 is shifted, the bolt position can be adjusted two-dimensionally and can be easily attached.
[0023]
The connecting member 2 attached to the panel 1 in this way is attached in advance to a structure 3 such as a road or a railway because at least four connecting members 2 are slidably attached to one panel. The bolt 23 of the connecting member 2 can be inserted into the fitting 34 of the mounting bar 33 while being appropriately moved, and there is no excessive screw fastening due to the displacement of the bolt, so that workability can be easily and smoothly performed. In addition, it is safe because the fastening strength as designed can be obtained.
[0024]
The rail 12b is formed by bending the back plate 12a of the panel 1. However, the rail 12b is not necessarily limited to this. For example, a bent beam or aluminum mold is attached to the back of the panel. The engaging portion of the connecting member may be inserted and slidable.
[0025]
Both ends of the rail 12b may be provided with a retaining structure so that the connecting member 2 does not fall out. However, the rail 23 interpolates the engaging portion 21 by tightening the bolt 23 to the mounting bar 33. Since 12b is guided in the direction of the mounting bar 33 and is tightly attached to the mounting bar, it will not necessarily fall out. Therefore, in the stage before the panel is mounted, it is better that the connecting member is not attached to the rail so that it does not interfere with the loading and transportation and does not get damaged. It is preferable that the connecting member is used by being inserted and slid from the end, because this is advantageous in terms of workability and cost.
[0026]
FIG. 5 is an installation diagram showing an embodiment in which the radio wave absorption panel is attached to the ceiling of the structure, and is attached to an attachment bar 33 attached via a suspension member 32 supported on the ceiling of the structure 3. The connecting member 2 is engaged with a rail 12b formed on the back surface of the panel 1, and the connecting member 2 is slid to an appropriate position and screwed and fastened. With this mounting structure, the radio wave absorption panel is attached to the entire ceiling surface so as to absorb unnecessary radio waves that become an obstacle when radio waves are exchanged between the facility and the vehicle.
[0027]
【The invention's effect】
A connecting member is slidably engaged with a rail having a cross-sectional shape key on the back side of the panel, and the connecting member is arranged so as to cross the rail, and attached to a mounting bar attached to the structure. Since it can be slidably mounted, the mounting of the panel can be adjusted two-dimensionally, so that the mounting work becomes easy. Therefore, there is no need to rework the hole position at the site. Further, by tightening the bolts of the connecting member, the panel and the mounting bar are integrated and fastened, so that the mounting effort can be simplified. Furthermore, since the back plate of the panel is bent to form a rail, it is not necessary to use an expensive aluminum mold, and the manufacturing cost can be reduced.
