Description

本発明は、アンテナ関係の架台、およびその製造方法に関する。すなわち、アンテナ又はその反射板が取付けられる架台、および、このような架台の製造方法に関するものである。   The present invention relates to an antenna-related gantry and a manufacturing method thereof. That is, the present invention relates to a gantry to which an antenna or its reflector is attached, and a method for manufacturing such a gantry.

《技術的背景》
アンテナは、送信機からの電波を空中に発射したり、空中を伝搬されてきた電波を受信して受信機に送るために、空中に張られた導線や導体よりなる。
そして電波の種類に応じ、バー状,ロッド状,ホーン状,放物面状,その他の2次曲面状等々、各種形状,構造のものがある。又、1枚や1個等の単素子からなるものと、複数枚や複数個等の多素子からなるものとがある。更に、単独で用いられるものと、反射板と共に用いられるものとがある。
《Technical background》
The antenna is composed of a conductor or a conductor stretched in the air in order to emit radio waves from the transmitter into the air or receive radio waves propagated through the air and send them to the receiver.
Depending on the type of radio wave, there are various shapes and structures such as a bar shape, a rod shape, a horn shape, a parabolic shape, and other quadric surface shapes. Further, there are ones composed of one or one single element, and ones composed of a plurality of elements such as plural or plural elements. Furthermore, there are one used alone and one used together with a reflector.

《従来の技術》
さて、例えば業務用等の大型のアンテナは、アンテナ素子(一次放射器)や反射板が、架台に取付けられると共に、懸架,張架,支持されているが、この種のアンテナ用の架台やアンテナ反射板用の架台は従来、次のように製造されていた。例えば放物面状,その他の2次曲面状をなす大型の架台は、次のように、型材やパイプ材等を主に溶接により組立てて行くことにより、製造されていた。
すなわち、例えばアルミ製のH型,I型,L型等の型材やパイプ材等の素材が、まず、機械加工機材にセットされて切り出され、それから、パイプベンダ,その他の整形加工機材を用いて曲げ加工等されていた。
それから、このように加工,準備された部材が、溶接により、所定形状,構造の架台へと組立てられ,形作られていた。そして、この溶接は、アンテナ素子や反射板が取付けられることに鑑み、極めて高い組立て精度が要求されており、もって溶接機と共に、溶接組立治具が必須的に使用されていた。
このように溶接対象の部材は、溶接にあたって、まず溶接組立治具を使用して所定位置に位置決め配置され、それから溶接機により溶接されていた。なお溶接組立治具は、このような位置決め機能と共に、溶接に際し溶接対象の部材について熱歪発生抑制機能を、発揮すべく使用されていた。
<Conventional technology>
Now, for example, large antennas for business use have antenna elements (primary radiators) and reflectors attached to a gantry, and are suspended, stretched, and supported. Conventionally, the reflector base has been manufactured as follows. For example, a large pedestal having a parabolic shape or other quadratic curved surface shape is manufactured by assembling a mold material or a pipe material mainly by welding as follows.
That is, materials such as aluminum H-type, I-type, and L-type materials and pipe materials are first set in machining equipment and cut out, and then used with pipe benders and other shaping equipment. It was bent.
Then, the members processed and prepared in this way were assembled and formed into a frame having a predetermined shape and structure by welding. This welding requires extremely high assembly accuracy in view of the fact that an antenna element and a reflector are attached, and therefore, a welding assembly jig is indispensable together with the welding machine.
As described above, the member to be welded is first positioned and arranged at a predetermined position using a welding assembly jig and then welded by a welding machine. In addition, the welding assembly jig has been used to exhibit a thermal strain generation suppressing function for a member to be welded together with such a positioning function.

ところで、このような従来のアンテナ関係の架台、およびその製造方法については、次の課題が指摘されていた。
《第1の問題点》
第1に、部材の加工,準備に手間や時間を要する、という問題が指摘されていた。すなわち、アンテナ素子や反射板が取付けられる架台であることに鑑み、その部材についても高精度であることが要求される。
そこで前述したように、型材やパイプ材等は、まず機械加工機材にセットされ、次に整形加工機材にセットされるが、これらのセットに手間や時間を要する、という指摘があった。又、整形加工機材として、3本ローラ−のように精度が得るのが難しい機材を使用することを要する等、高精度な部材の加工,準備が容易でなかった。もって、機械加工機材や整形加工機材等の使用機材自体のコストも相俟って、架台の製造コストが嵩む、という問題が指摘されていた。
By the way, the following subject was pointed out about such a conventional antenna-related mount and its manufacturing method.
<First problem>
First, a problem has been pointed out that labor and time are required for processing and preparation of members. That is, in view of the pedestal on which the antenna element and the reflection plate are attached, the member is required to have high accuracy.
Therefore, as described above, the mold material, pipe material, and the like are first set on machining equipment and then set on shaping equipment, but it has been pointed out that these sets require time and effort. In addition, it is not easy to process and prepare a high-precision member because it is necessary to use a shaping machine such as a three-roller that is difficult to obtain. Therefore, it was pointed out that the manufacturing cost of the gantry increases due to the cost of the equipment used itself such as machining equipment and shaping equipment.

《第2の問題点》
第2に、加工,準備された部材は、溶接により、所定形状,構造の架台へと組立てられて行くが、このような溶接に際しては、前述したように高度の精度要求に鑑み、位置決め用等に溶接組立治具が使用されていた。
もってその分、溶接に手間と時間を要すると共に、溶接機や溶接組立治具等の使用機材自体のコストも相俟って、架台の製造コストが嵩む、という問題が指摘されていた。特に少量生産の場合、溶接組立治具使用によるコスト高が、顕著となっていた。
更に、溶接組立治具を使用しても、溶接に際し溶接対象の部材に熱歪が発生し、その修正に多くの手間を要しており、この面からも架台の製造コストが嵩む、という問題が指摘されていた。
<< Second problem >>
Secondly, the processed and prepared members are assembled into a frame having a predetermined shape and structure by welding. In such welding, in consideration of the high accuracy requirement as described above, for positioning, etc. A welding assembly jig was used.
Therefore, it has been pointed out that welding requires much time and time for welding, and the cost of the equipment itself such as a welding machine and a welding assembly jig is combined with the manufacturing cost of the mount. In particular, in the case of small-scale production, the high cost due to the use of a welding assembly jig has become prominent.
Furthermore, even when a welding assembly jig is used, thermal distortion occurs in the member to be welded at the time of welding, and it takes a lot of labor to correct it, and this also increases the manufacturing cost of the gantry. Was pointed out.

《第3の問題点》
第3に、質量や強度面にも、問題が指摘されていた。すなわち、まず準備される部材に関し、溶接に対応困難な材質や肉薄のものは使用できず、もって、架台の質量増加を招くことがあった。
又、軽量化を図るためアルミ等に代表される熱処理材を部材として用いる場合は、溶接による熱により、素材の熱処理が阻害され、もって架台の強度低下を招くことがあった。対策としては、部材の肉厚を増加させる必要が生じ、結果的に架台の質量とコストの増加を招く、という問題が指摘されていた。
《Third problem》
Third, problems have been pointed out in terms of mass and strength. That is, regarding the members to be prepared, materials and thin materials that are difficult to be welded cannot be used, and the mass of the gantry may be increased.
Further, when a heat treatment material typified by aluminum or the like is used as a member in order to reduce the weight, the heat treatment of the material is hindered by the heat from welding, and the strength of the gantry may be reduced. As a countermeasure, it has been pointed out that the thickness of the member needs to be increased, resulting in an increase in the mass and cost of the gantry.

《本発明について》
本発明のアンテナ関係の架台、およびその製造方法は、このような実情に鑑み、上記従来技術の課題を解決すべくなされたものである。
そして本発明は、第1に、部材の加工,準備が、高精度に行われると共に容易化され、第2に、組立ても、高精度に行われると共に容易化され、第3に、しかも軽量,高強度で,低コストな、アンテナ関係の架台およびその製造方法を提案することを、目的とする。

この製造方法では、アルミ,その他の金属平板材4が、素材として用いられる。金属平板材4としては、強度向上等の目的で熱処理が施された熱処理材も、使用可能である。
そして金属平板材4は、まず、例えばレーザー切断機,タレットパンチプレス,その他公知の板材切断機やプレス機械を使用して板金加工、つまり所定部位つまり各接合対象部位について取付孔9が穿設されると共に、所定形状に切断又は打ち抜き加工される。それから、このように加工された各金属平板材4は、プレスブレーキ,その他の折曲機を使用して折曲加工されて、所定形状に2次元曲げされる。
このような工程を辿ることにより、金属平板材4を素材として、塑性加工により外枠および基幹部材5が製作される。なお、量産の場合は、型を用いることにより、プレス機械にて切断や打ち抜きと折曲とを、同時実施することも可能である。
<< Details of the Invention >>
Hereinafter, the present invention will be described in more detail. First, the manufacturing method of the mount 1 for the antenna element 2 and the antenna reflector (hereinafter simply referred to as reflector) 3 of the present invention is as follows.
In this manufacturing method, aluminum or other metal flat plate 4 is used as a material. As the metal flat plate 4, a heat treatment material that has been heat-treated for the purpose of improving the strength can also be used.
The metal flat plate 4 is first formed by using, for example, a laser cutting machine, a turret punch press, and other known plate cutting machines and press machines, that is, a mounting hole 9 is drilled at a predetermined portion, that is, each joining target portion. At the same time, it is cut or punched into a predetermined shape. Then, each metal flat plate 4 processed in this way is bent using a press brake or other bending machine and is two-dimensionally bent into a predetermined shape.
By following such a process, the outer frame and the basic member 5 are manufactured by plastic working using the flat metal plate 4 as a raw material. In the case of mass production, it is possible to simultaneously perform cutting, punching and bending with a press machine by using a die.

この製造方法では、このように金属平板材4にて、板金曲げ構造の外枠および基幹部材5が、製作される。すなわち、金属平板材4を、切断,打ち抜き,折曲等塑性加工することにより、外枠や基幹部材5が製作される。なお外枠は、このような板金曲げ構造に限定されるものではなく、例えば、角パイプ等の型材組み付け構造のものも可能である。
そして、このように製作された基幹部材5は、外枠と共に一定形状の基幹構造7へと組立てられて行く。すなわち外枠と基幹部材5は、相互間が、リベット又はボルトナット更には接着剤等の接合手段6を用いて取付け,結合されることにより、所定形状,構造のアンテナ2や反射板3に対応した一定形状へと、例えば略3次曲面状に組立てられる(例えば、図1の各図,図2,図3等を参照)。
リベットやボルトナット等の接合手段6は、前述により外枠および基幹部材5の接合対象部位に多数穿設されていた取付孔9を利用することにより、所定位置にて取付け,結合を実施する。接着剤は、リベットやボルトナット等による取付け,結合に際し、必要に応じ、補助的な接合手段6として使用される。
In this manufacturing method, the outer frame of the sheet metal bending structure and the basic member 5 are manufactured using the metal flat plate material 4 in this way. That is, the outer frame and the core member 5 are manufactured by plastic processing such as cutting, punching, and bending the metal flat plate material 4. It should be noted that the outer frame is not limited to such a sheet metal bending structure, and for example, a mold material assembly structure such as a square pipe is also possible.
And the basic member 5 manufactured in this way is assembled into the basic structure 7 of a fixed shape together with the outer frame. In other words, the outer frame and the core member 5 are attached and joined to each other using a joining means 6 such as a rivet, a bolt and a nut, or an adhesive, thereby corresponding to the antenna 2 and the reflector 3 having a predetermined shape and structure. The fixed shape is assembled into, for example, a substantially cubic curved surface (see, for example, each figure of FIG. 1, FIG. 2, FIG. 3, etc.).
The joining means 6 such as rivets and bolts and nuts are attached and joined at a predetermined position by using the attachment holes 9 formed in the outer frame and the joining target portions of the basic member 5 as described above. The adhesive is used as auxiliary joining means 6 as needed when mounting and joining with rivets, bolts and nuts, and the like.

このような工程を辿ることにより、外枠と各基幹部材5にて基幹構造7が組立てられ、もって、アンテナ2用や反射板3用の架台1が製造される。製造された架台1は、基幹構造7を構成する外枠と基幹部材5と、外枠と基幹部材5間を取付け,結合する接合手段6とを、有してなる。
ところで、リブ8については次のとおり。リブ8は、例えば大型の架台1の基幹構造7について、その剛性,強度を増す目的で、付加的に採用される(図2,図3,図4等を参照)。
そしてリブ8は、基幹部材5に準じた板金曲げ構造よりなり、つまり、金属平板材4について切断,打ち抜き,折曲,取付孔9穿設等の加工を施して、製作される。そして、基幹構造7の組立に際し、リベット,ボルトナット,接着剤等の接合手段6により、必要に応じて各基幹部材5間及び基幹部材5と外枠との間に取付けられる。更にリブ8は、基幹構造7にアンテナ素子2や反射板3を取付けるために、使用されることもある(図2を参照)。
又、更なる剛性,強度向上策として、基幹部材5とリブ8のフランジ同士を三角,矩形,その他形状のプレートで接合したり、直接該フランジ同士を重ねて接合することも考えられる。
本発明の詳細については、以上のとおり。
By following such a process, the basic structure 7 is assembled by the outer frame and each basic member 5, and the gantry 1 for the antenna 2 and the reflector 3 is manufactured. The manufactured gantry 1 includes an outer frame and a main member 5 constituting the basic structure 7, and a joining means 6 for attaching and connecting the outer frame and the main member 5.
By the way, the rib 8 is as follows. The rib 8 is additionally employed, for example, for the purpose of increasing the rigidity and strength of the backbone structure 7 of the large gantry 1 (see FIG. 2, FIG. 3, FIG. 4, etc.).
The rib 8 has a sheet metal bending structure in conformity with the core member 5, that is, the metal flat plate member 4 is manufactured by processing such as cutting, punching, bending, and mounting hole 9 drilling. And when assembling the basic structure 7, it is attached between the basic members 5 and between the basic member 5 and the outer frame as required by the joining means 6 such as rivets, bolts and nuts, adhesives and the like. Further, the rib 8 may be used to attach the antenna element 2 or the reflector 3 to the basic structure 7 (see FIG. 2).
Further, as a measure for further improving rigidity and strength, it is conceivable to join the flanges of the basic member 5 and the ribs 8 with a triangular, rectangular, or other shaped plate, or to directly overlap the flanges.
The details of the present invention are as described above.

《作用等》
本発明のアンテナ関係の架台1、およびその製造方法は、以上説明したように構成されている。そこで、以下のようになる。
(1)この製造方法では、架台1の基幹構造7を構成する外枠と各基幹部材5が、予め製作される。
そして、外枠と基幹部材5の製作は、公知のレーザー切断機,タレットパンチプレス,プレスブレーキ,その他の板材切断機やプレス機械を用いて、素材である金属平板材4を、切断,打ち抜き,折曲,取付孔あけ等、塑性加工することにより行われる。もって外枠や各基幹部材5は、簡単容易に、しかも精度高く加工,準備される。
《Action etc.》
The antenna-related gantry 1 and the manufacturing method thereof according to the present invention are configured as described above. Therefore, it becomes as follows.
(1) In this manufacturing method, the outer frame and the basic members 5 constituting the basic structure 7 of the gantry 1 are manufactured in advance.
The outer frame and the core member 5 are manufactured by cutting and punching the metal flat plate 4 as a material using a known laser cutting machine, turret punch press, press brake, other plate cutting machine or press machine. This is done by plastic working such as bending and mounting holes. Accordingly, the outer frame and each basic member 5 are processed and prepared easily and easily with high accuracy.

(2)それから、この製造方法では、このように製作された各基幹部材5と外枠間を、リベット,ボルトナット,接着剤等、溶接によらない接合手段6により、取付け,結合することにより、基幹構造7が組立てられる(図1の各図,図2等を参照。なお、図1の(1)図の適用例は更にプレート付よりなり、図2の適用例はリブ8付よりなる)。もって、この架台1の基幹構造7は、簡単容易にしかも精度高く組立てられる。
特に、外枠や各基幹部材5の接合対象部位に各取付孔9を穿設しておくことにより、リベットやボルトナット等の接合手段6にて、外枠と各基幹部材5間が正確な所定位置関係で取付け,接合されるようになる(図2,図3,図4等を参照)。すなわち外枠と各基幹部材5と外枠間が、簡単容易に、しかも必然的に所定位置関係で位置決め配置され、もって基幹構造7が、精度高く組立てられる。
又、溶接によらないので、外枠および各基幹部材5に熱歪発生の虞がなく、この面からも、基幹構造7が精度高く組立てられる。
(2) Then, in this manufacturing method, the base member 5 and the outer frame manufactured in this way are attached and joined by joining means 6 such as rivets, bolts and nuts, adhesives, etc. not based on welding. The basic structure 7 is assembled (see each figure in FIG. 1, FIG. 2 and the like. Note that the application example of FIG. 1 (1) further includes a plate, and the application example of FIG. ). Therefore, the basic structure 7 of the gantry 1 can be easily and easily assembled with high accuracy.
In particular, by forming each mounting hole 9 in the outer frame and the part to be joined of each basic member 5, it is possible to accurately connect the outer frame and each basic member 5 by the joining means 6 such as a rivet or a bolt and nut. They are attached and joined in a predetermined positional relationship (see FIGS. 2, 3 and 4). That is, the outer frame, each of the basic members 5 and the outer frame are simply and easily positioned and inevitably positioned in a predetermined positional relationship, so that the basic structure 7 is assembled with high accuracy.
Further, since it is not based on welding, there is no possibility of thermal distortion occurring in the outer frame and each basic member 5, and the basic structure 7 can be assembled with high accuracy from this aspect.

(3)この製造方法では、リベット,ボルトナット,接着剤等、溶接によらない接合手段6が採用されているので、更に次のようになる。
まず、肉薄の素材つまり肉薄の金属平板材4,外枠,基幹部材5を、使用可能となる。又、アルミ等の熱処理材を、金属平板材4,外枠,基幹部材5として用いても、熱処理の無効化,強度低下の虞がなく、もってこの面からも、肉薄の金属平板材4,外枠,基幹部材5を、使用可能となる。更に、熱歪発生の虞がないので、金属平板材4,外枠,基幹部材5について、強度低下の虞もない。
(3) In this manufacturing method, since the joining means 6 not based on welding, such as a rivet, a bolt nut, and an adhesive, is employed, it is further as follows.
First, a thin material, that is, a thin metal flat plate 4, an outer frame, and a basic member 5 can be used. Further, even if a heat treatment material such as aluminum is used as the metal flat plate 4, outer frame, and core member 5, there is no fear of invalidation of heat treatment and a decrease in strength. The outer frame and the basic member 5 can be used. Furthermore, since there is no possibility of thermal distortion, the strength of the metal flat plate member 4, the outer frame, and the core member 5 is not reduced.

(4)このようにして、架台1が製造され、もって架台1は、基幹構造7を構成する外枠と基幹部材5と、外枠と各基幹部材5間を取付け,結合する接合手段6とを、有している(図1の各図,図2を参照。なお、図1の(1)図の適用例は更にプレート付よりなり、図2の適用例はリブ8付よりなる)。
なお、架台1の剛性,強度向上のため、基幹構造7の基幹部材5にリブ8を付加した構成も、考えられる(図2,図3,図4等を参照)。又、更なる剛性,強度向上のため、基幹部材5とリブ8のフランジの片面もしくは両面にプレートを付加した構成も、考えられる。
(4) In this way, the gantry 1 is manufactured, and the gantry 1 includes an outer frame and a basic member 5 constituting the basic structure 7, and joining means 6 for attaching and coupling the outer frame and each basic member 5. (Refer to FIG. 1 and FIG. 2. Note that the application example of FIG. 1 (1) further includes a plate, and the application example of FIG. 2 includes a rib 8).
In addition, the structure which added the rib 8 to the basic | foundation member 5 of the basic | foundation structure 7 for the rigidity and intensity | strength of the mount frame 1 is also considered (refer FIG.2, FIG.3, FIG.4 etc.). Further, in order to further improve the rigidity and strength, a configuration in which plates are added to one side or both sides of the flanges of the basic member 5 and the rib 8 is also conceivable.

(5)そして架台1に、アンテナ素子2又は反射板3が取付けられると共に、懸架,張架,支持される。
アンテナのアンテナ素子(一次放射器)2は、金属導体製よりなるが、背景技術の欄にも記載したように、ホーン状,放物面状,その他の2次曲面状等々、各種の形状,構造のものがあると共に、1枚や1個等の単素子よりなるものと、複数枚や複数個等の多素子からなるものとがある。反射板3の形状等についてもアンテナに準じるが、金網,その他の各種メッシュ,エキスパンドメタル,等々も使用される。
いずれにしても架台1は、このようなアンテナ素子2や反射板3を取付けると共に、懸架,張架,支持するに足る一定形状をなす。その取付けには、リベット,ボルトナット,ピン,ワイヤ,接着,その他各種の取付方式が用いられる。
(5) The antenna element 2 or the reflecting plate 3 is attached to the gantry 1 and is suspended, stretched and supported.
The antenna element (primary radiator) 2 of the antenna is made of a metal conductor, but as described in the background section, various shapes such as a horn shape, a parabolic surface shape, other secondary curved surface shapes, etc. In addition to the structure, there are a single element such as one or one element and a multi-element such as a plurality or plural elements. The shape and the like of the reflecting plate 3 also conforms to the antenna, but a wire mesh, other various meshes, expanded metal, and the like are also used.
In any case, the gantry 1 has such a fixed shape as to mount the antenna element 2 and the reflector 3 and to suspend, stretch and support the gantry. For the attachment, rivets, bolts and nuts, pins, wires, adhesion, and other various attachment methods are used.

(6)ここで、各図示適用例等について述べておく。まず、図1の(2)図,(3)図に示した適用例の架台1では、金網製の反射板3の裏面が、基幹構造7のリブ8や基幹部材5に取付けられている。
つまり、図示適用例の架台1では、反射板3は、基幹構造7に懸架,張架,支持されている。又、アンテナ素子2としては、ホーン状タイプものが1個用いられており、ロッド11を介し、搭載ベース12に取付け保持されている。このような適用例としては、放射器(アンテナ2)と反射鏡(反射板3)とを備えたパラボラアンテナ装置が、代表的である。
(6) Here, each illustrated application example will be described. First, in the gantry 1 of the application example shown in FIGS. 2 (2) and 3 (3), the rear surface of the reflector 3 made of wire mesh is attached to the rib 8 or the backbone member 5 of the backbone structure 7.
That is, in the gantry 1 of the illustrated application example, the reflector 3 is suspended, stretched, and supported by the basic structure 7. In addition, as the antenna element 2, one horn type is used, and is mounted and held on the mounting base 12 via the rod 11. A typical example of such an application is a parabolic antenna device including a radiator (antenna 2) and a reflecting mirror (reflecting plate 3).

(7)又、図1の(1)図に示した適用例の架台1では、基幹構造7に、各基幹部材5の正面側,表側,凹面側に取付穴部13を形成するプレートを備えており、この各取付穴部13に、それぞれホーン状タイプのアンテナ素子2が、挿着取付けされている。   (7) Moreover, in the gantry 1 of the application example shown to (1) figure of FIG. 1, the base structure 7 is equipped with the plate which forms the attachment hole part 13 in the front side, front side, and concave surface side of each basic member 5. The horn-shaped antenna element 2 is inserted and attached to each mounting hole 13.

(8)更に、図2,図3,図4に示した適用例の架台1では、外枠や略コの字チャンネル状やZ型断面状の各基幹部材5(図2,図3,図4の(1)図を参照)と、同様に略コの字チャンネル状やZ型断面状の各リブ8(図2,図3,図4の(2)図そして(3)図を参照)と、が用いられており、基幹構造7へと組立てられている(図2を参照)。
そして正面側に、反射板3を、基幹構造7の各基幹部材5やリブ8の所定点に対し取付けられると共に、懸架,張架,支持されることにより、放物面となる。なおこれによらず、各基幹部材5や各リブ8に対して取付穴部13を形成する多数のプレートを取り付けると、前述した図1の(1)図の適用例となり、この各取付穴部13に対し、ホーン状のアンテナ素子2を挿着,取付けする例も可能である。
(8) Furthermore, in the gantry 1 of the application example shown in FIGS. 2, 3, and 4, each basic member 5 having an outer frame, a substantially U-shaped channel shape, or a Z-shaped cross section (see FIGS. 2, 3, and 4). 4 (see FIG. 4 (1)) and each rib 8 having a substantially U-shaped channel shape or a Z-shaped cross section (see FIGS. 2, 3 and 4 (2) and (3)) And are assembled into the backbone structure 7 (see FIG. 2).
On the front side, the reflector 3 is attached to a predetermined point of each of the basic members 5 and ribs 8 of the basic structure 7 and becomes a paraboloid by being suspended, stretched and supported. Regardless of this, if a large number of plates forming the attachment hole 13 are attached to each basic member 5 or each rib 8, the application example shown in FIG. An example in which a horn-shaped antenna element 2 is inserted and attached to 13 is also possible.

(9)更に、次のような例も考えられる(図示せず)。すなわち、上述した当該プレートを裏面にも適用した架台1も、考えられる。すなわち、桁としての基幹部材5やリブ8を両面でプレートによりサンドイッチすることで、強度や剛性が一段と高まる。その場合、両面のプレート形状は任意であるが、帯状にスリットを入れたものは、3次曲面への密着が容易になる利点がある。この場合は、リブ8なしも可である。
作用等については、以上のとおり。
(9) Further, the following example is also conceivable (not shown). That is, a gantry 1 in which the plate described above is also applied to the back surface is also conceivable. That is, the strength and rigidity are further increased by sandwiching the basic member 5 and the ribs 8 as girders on both sides with plates. In that case, the shape of the plates on both sides is arbitrary, but the one with slits in the strip shape has the advantage that it is easy to adhere to the cubic curved surface. In this case, the rib 8 can be omitted.
As for the action, it is as above.
