Description

本発明は、支持柱補強部材に関する。   The present invention relates to a support column reinforcing member.

移動無線通信システムでは、音声通話用の信号の伝送や各種情報の伝送を行うネットワークに接続された基地局と移動無線端末との間で無線通信を行うことにより、移動無線端末によって音声通話や各種情報の送受信を行うことが可能になっている。このような基地局で用いられる無線通信用のアンテナは、基地局が設置される場所によって様々な種類のものがあり、例えば、街中の屋外に設置される基地局では、街中にあるビル等の建物の壁面や屋上等に設置される。これにより、アンテナは比較的高い位置に設置されるため、移動無線端末との間で無線通信を行う際に、電波が障害物に反射したり回折したりすることを極力抑えることができ、想定したサービスエリア内において基地局と移動無線端末との間で、効率的に強い電波で通信を行うことができるようにしている。   In a mobile radio communication system, a mobile radio terminal performs radio communication between a base station and a mobile radio terminal connected to a network for transmitting a voice call signal and transmitting various information. It is possible to send and receive information. There are various types of antennas for wireless communication used in such base stations depending on the location where the base station is installed. For example, in a base station installed outdoors in a city, such as a building in the city It is installed on the wall of the building or the rooftop. As a result, since the antenna is installed at a relatively high position, it is possible to suppress radio waves from being reflected or diffracted by obstacles as much as possible when performing wireless communication with mobile radio terminals. In this service area, the base station and the mobile radio terminal can communicate efficiently with strong radio waves.

しかし、建物の高い位置にアンテナを設置した場合、強風や地震等が発生した際に、アンテナを支持する支持柱に大きな荷重が作用することがある。このため、従来の基地局の中には、支持柱の補強を行っているものがある。例えば、特許文献１に記載された支持柱一体型空中線では、外筒としてアンテナと一体に形成される支持柱内に補強材を充填することにより、支持柱の補強を行っている。また、特許文献２に記載された支柱支持器具では、アンテナ支柱の補強を行う際における利便性を向上させるため、２つの部材に分割された支柱把持部でアンテナ支柱を挟み込むことによりアンテナ支柱に支柱把持部を取り付け、支柱把持部に補強用のワイヤを連結することにより、アンテナ支柱の補強を行っている。また、特許文献３に記載されたアンテナの制振構造では、アンテナの制振を行うために、アンテナカバーに上部固定板を取り付け、アンテナ支柱におけるアンテナカバーの近傍に下部固定板を取り付け、これらの上部固定板と下部固定板との間に制振用ロープと制振バネとを配設してアンテナカバーに張力を与えることにより、アンテナカバーの折損を防止している。   However, when an antenna is installed at a high position in a building, a large load may act on a support column that supports the antenna when a strong wind or an earthquake occurs. For this reason, some conventional base stations reinforce support pillars. For example, in the support column integrated aerial wire described in Patent Document 1, the support column is reinforced by filling a support column formed integrally with the antenna as an outer cylinder. Moreover, in the support | pillar support fixture described in patent document 2, in order to improve the convenience at the time of reinforcing an antenna support | pillar, a support | pillar is attached to an antenna support | pillar by inserting | pinching an antenna support | pillar with the support | pillar holding part divided | segmented into two members The antenna support is reinforced by attaching a grip and connecting a reinforcing wire to the support grip. Further, in the antenna damping structure described in Patent Document 3, an upper fixing plate is attached to the antenna cover and a lower fixing plate is attached in the vicinity of the antenna cover in the antenna column to perform damping of the antenna. A damping rope and a damping spring are disposed between the upper fixing plate and the lower fixing plate to apply tension to the antenna cover, thereby preventing the antenna cover from being broken.

ここで、近年では、移動無線通信システムを用いて通信を行う際における情報量が大幅に多くなっており、基地局で処理をする情報量や通信量も多くなっている。このため、基地局によっては、情報量の増大に合わせて、基地局で用いられる電波の周波数帯を増やすことにより複数の周波数帯に対応した共用アンテナや無線機に交換が必要な場合や、増設する周波数帯に対応したアンテナ及び無線機の増設が必要になることがある。一方、情報量の増大に合わせて、通信量を多くすることができる共用アンテナへの交換やアンテナ増設により、支柱が支える重量や風による受風面積が増加することがある。アンテナの重量や受風面積が大きくなる場合には、強風や地震の発生時にアンテナを支持する支持柱に作用する大きな荷重に対応できるように、支持柱を強度が高いものに交換するか、支持柱を補強する必要がある。   Here, in recent years, the amount of information when performing communication using a mobile radio communication system has greatly increased, and the amount of information and the amount of communication processed by the base station has also increased. For this reason, depending on the base station, if the frequency of the radio wave used by the base station is increased as the amount of information increases, it may be necessary to replace a shared antenna or radio that supports multiple frequency bands, or It may be necessary to add antennas and radios corresponding to the frequency band to be used. On the other hand, as the amount of information increases, the weight received by the column and the wind receiving area may increase due to the exchange to the common antenna that can increase the communication amount or the addition of the antenna. If the antenna weight or wind receiving area increases, replace the support column with one with higher strength or support so that it can handle the large load acting on the support column that supports the antenna in the event of strong wind or earthquake. It is necessary to reinforce the pillar.

支持柱を補強する手法としては、特許文献１のように支持柱内に補強材を充填する手法があるが、支持柱内に補強材を充填する際には、アンテナからの電波の送信を長時間停止した状態で行う必要がある。しかし、移動無線通信システムは、現代では社会生活において重要なシステムであり、電波を長時間停止すると、その基地局でカバーするエリア内では、一部のエリアでは通信が困難になる移動無線端末が生じたり、通信品質の低下が生じたりすることになる。このため、電波の停止は短時間で行うのが好ましい。   As a method of reinforcing the support column, there is a method of filling the support column with a reinforcing material as in Patent Document 1, but when filling the support column with the reinforcing material, transmission of radio waves from the antenna is lengthened. It is necessary to do it in a state of stopping for a time. However, the mobile radio communication system is an important system in social life at present, and if radio waves are stopped for a long time, there are mobile radio terminals that are difficult to communicate in some areas within the area covered by the base station. Or communication quality may be degraded. For this reason, it is preferable to stop radio waves in a short time.

支持柱の補強を短時間で行う手法としては、特許文献２のように、２つの部材に分割された部材でアンテナ支柱を挟み込み、この部材に補強用のワイヤを複数連結することによりアンテナ支柱の補強する手法があるが、支持柱にワイヤを連結し、複数のワイヤで補強を行った場合、支持柱を設置する側にもワイヤの他端を連結する必要がある。例えば、建物の屋上にアンテナを設置する場合、ワイヤにおいて支持柱に連結されている側の端部の反対側の端部を屋上に連結し、複数のワイヤによって複数の方向から支持柱に対して張力を付与することにより、支持柱を補強する必要がある。このため、屋上には、ワイヤの端部を連結するための広いエリアが必要になり、このようなエリアを確保できない場合は、支持柱を補強することが困難になることがある。また、ワイヤの端部を連結するためのエリアを確保できたとしても、従来に比べてより広い範囲を建物所有者から賃借する必要があるため、結果として通信事業者の設備維持費用が増加する可能性が高い。   As a method of reinforcing the support column in a short time, as in Patent Document 2, the antenna column is sandwiched between members divided into two members, and a plurality of reinforcing wires are connected to the member to thereby reinforce the antenna column. There is a method of reinforcing, but when a wire is connected to a support column and reinforcement is performed with a plurality of wires, it is necessary to connect the other end of the wire to the side where the support column is installed. For example, when an antenna is installed on the roof of a building, the end of the wire opposite to the end connected to the support column is connected to the roof, and the plurality of wires are connected to the support column from a plurality of directions. It is necessary to reinforce the support column by applying tension. For this reason, a wide area for connecting the ends of the wires is required on the roof, and if such an area cannot be ensured, it may be difficult to reinforce the support pillar. In addition, even if the area for connecting the ends of the wires can be secured, it is necessary to rent a wider area from the owner of the building than before, resulting in an increase in equipment maintenance costs for the carrier. Probability is high.

また、アンテナを交換した際には、特許文献３のようにアンテナカバーに対して張力を与えることにより、強風や地震等により生じるアンテナカバーの振動を抑制し、アンテナカバーの折損を防止する対策を取ることも考えられるが、アンテナカバーの制振を行ったとしても、強風や地震の発生時に支持柱に作用する大きな荷重に対しては、対応することができない。これらのように、アンテナが設置されている部分の周囲のエリアを用いることなく、アンテナを支持する支持柱の補強を短い時間で行うことは、大変困難なものとなっていた。   In addition, when the antenna is replaced, a measure is taken to prevent the antenna cover from being broken by applying tension to the antenna cover as in Patent Document 3 to suppress the vibration of the antenna cover caused by strong winds or earthquakes. Although it can be considered, even if the antenna cover is damped, it cannot cope with a large load acting on the support column when a strong wind or earthquake occurs. As described above, it has been very difficult to reinforce the support pillar supporting the antenna in a short time without using the area around the portion where the antenna is installed.

本発明は、上記に鑑みてなされたものであって、アンテナを支持する支持柱の補強を容易に行うことができる支持柱補強部材を提供することを目的とする。   This invention is made | formed in view of the above, Comprising: It aims at providing the support pillar reinforcement member which can reinforce the support pillar which supports an antenna easily.

The second reinforcing member (see FIG. 9 and FIG. 10) attached at a position different from the first reinforcing member in FIG. 9 is formed in a rod shape and between the first reinforcing member and the second reinforcing member.

It is preferable that it is attached to the said support pillar by doing.

The length of the mounting flange 35 provided in this way in the longitudinal direction of the reinforcing bracket main body 34 is substantially the same as the length of the reinforcing bracket main body 34 in the same direction. Further, the mounting flange 35 is formed with a bolt hole 63 through which the reinforcing bracket mounting bolt 61 is inserted. When the first member 32 and the second member 33 are joined, the reinforcing bracket is attached to the bolt hole 63. The bolt 61 can be inserted.

また、補強棒鋼連結部３６は、補強金具本体部３４の長手方向における一端側に接続されており、補強金具本体部３４の長手方向に厚さ方向が向く向きで配設されている。この補強棒鋼連結部３６は、補強金具本体部３４の一端側におけるＬ字の優角側に配設されており、取付フランジ３５が補強金具本体部３４から突出する方向における長さが、２つの取付フランジ３５における、互いに他方の取付フランジ３５が位置する側の端部の反対側の端部同士の距離と同じ長さになっている。これにより、補強棒鋼連結部３６は、２つ取付フランジ３５と、補強金具本体部３４の一端側におけるＬ字の優角側の面に接続されている。   Further, the reinforcing steel bar connecting portion 36 is connected to one end side in the longitudinal direction of the reinforcing metal fitting main body 34, and is arranged with the thickness direction facing the longitudinal direction of the reinforcing metal fitting main body 34. The reinforcing steel bar connecting portion 36 is disposed on the L-shaped dominant side on one end side of the reinforcing bracket main body 34, and the length in the direction in which the mounting flange 35 protrudes from the reinforcing bracket main body 34 is two. The mounting flange 35 has the same length as the distance between the ends opposite to the ends where the other mounting flange 35 is located.

このように、取付フランジ３５と補強金具本体部３４とに接続される補強棒鋼連結部３６には、補強棒鋼６０が挿通される穴である補強棒鋼連結穴３７が形成されている。補強棒鋼連結穴３７は、２つの取付フランジ３５が補強金具本体部３４から突出する方向における補強棒鋼連結部３６の両端付近の２箇所に形成されている。つまり、補強棒鋼連結穴３７は、第１部材３２の補強棒鋼連結部３６と第２部材３３の補強棒鋼連結部３６のそれぞれに２箇所ずつ形成されており、上側補強金具３１全体では４箇所に形成されている。これらの補強棒鋼連結穴３７は、上側補強金具３１を支持柱５に取り付けた際における支持柱５の中心からの距離、即ち、略円柱状に形成される支持柱５の軸心からの距離が、フランジ状の連結部７の半径よりも大きくなっている。   As described above, the reinforcing bar connecting portion 36 connected to the mounting flange 35 and the reinforcing metal fitting main body 34 is formed with the reinforcing bar connecting hole 37 that is a hole through which the reinforcing bar 60 is inserted. The reinforcing steel bar connecting holes 37 are formed at two locations near both ends of the reinforcing steel bar connecting part 36 in the direction in which the two attachment flanges 35 protrude from the reinforcing metal fitting main body part 34. That is, the reinforcing steel bar connecting holes 37 are formed at two places in each of the reinforcing steel bar connecting part 36 of the first member 32 and the reinforcing bar steel connecting part 36 of the second member 33, and there are four places in the upper reinforcing metal fitting 31 as a whole.

It is larger than the radius of the flange-like connecting portion 7.

また、リブ３８は、補強棒鋼連結部３６における補強金具本体部３４が延在する面側に配設されている。リブ３８は、１つの補強棒鋼連結部３６に２つが接続されており、補強棒鋼連結部３６に接続される２つの取付フランジ３５に対応して配設されている。つまり、各リブ３８は、補強棒鋼連結部３６における補強金具本体部３４が延在する面側で、補強棒鋼連結部３６と取付フランジ３５とに接続されている。このように設けられるリブ３８は、厚さ方向が、２つの取付フランジ３５が補強金具本体部３４から突出する方向を向く板状の形状で形成されており、補強金具本体部３４の長さ方向における長さが、同方向における補強金具本体部３４の長さとほぼ同じ長さになっている。   Moreover, the rib 38 is arrange | positioned by the surface side in which the reinforcement metal fitting main-body part 34 in the reinforcement bar connecting part 36 extends. Two ribs 38 are connected to one reinforcing bar connecting portion 36, and are arranged corresponding to two mounting flanges 35 connected to the reinforcing bar connecting portion 36. That is, each rib 38 is connected to the reinforcing bar connecting portion 36 and the mounting flange 35 on the surface side of the reinforcing bar connecting portion 36 where the reinforcing metal fitting main body 34 extends. The ribs 38 thus provided are formed in a plate shape in which the thickness direction faces the direction in which the two mounting flanges 35 protrude from the reinforcing bracket main body 34, and the length direction of the reinforcing bracket main body 34 is Is substantially the same as the length of the reinforcing metal fitting main body 34 in the same direction.

これらのよう構成される上側補強金具３１は、第１部材３２と第２部材３３の補強金具本体部３４の劣角側が互いに対向し、それぞれの補強棒鋼連結部３６が、下側補強金具４１が位置する側の反対側に位置する向きで、第１部材３２と第２部材３３で、支持柱５を挟み込む。即ち、第１部材３２と第２部材３３のそれぞれの補強金具本体部３４の劣角側の面が、支持柱５の外周面に接触する状態で、支持柱５を挟み込む。この状態で、取付フランジ３５に形成される補強金具取付ボルト６１用のボルト穴６３に補強金具取付ボルト６１を通し、補強金具取付ボルト６１とナット６２とを螺合することにより、支持柱５に対して、第１部材３２と第２部材３３とで挟み込む方向の力を付与する。これにより、第１部材３２及び第２部材３３と、支持柱５との間には、大きな摩擦力が発生し、上側補強金具３１は、２つの補強金具本体部３４と支持柱５との間に発生する摩擦力により、支持柱５に取り付けられる。換言すると、上側補強金具３１は、複数の分割部材である第１部材３２と第２部材３３とに分割され、第１部材３２と第２部材３３とで支持柱５を挟み込んで第１部材３２と第２部材３３を結合することにより支持柱５に取り付けられる。   In the upper reinforcing metal fitting 31 configured as described above, the inferior angles of the reinforcing metal body 34 of the first member 32 and the second member 33 face each other, and the reinforcing steel bar connecting portions 36 are connected to the lower reinforcing metal fitting 41.

In this state, the reinforcing bracket mounting bolt 61 is passed through the bolt hole 63 for the reinforcing bracket mounting bolt 61 formed in the mounting flange 35, and the reinforcing bracket mounting bolt 61 and the nut 62 are screwed together. On the other hand, a force in a direction to be sandwiched between the first member 32 and the second member 33 is applied. As a result, a large frictional force is generated between the first member 32 and the second member 33 and the support column 5, and the upper reinforcing bracket 31 is located between the two reinforcing bracket main bodies 34 and the support column 5. It is attached to the support column 5 by the frictional force generated in.

When exchanging the antenna 1 without exchanging the support column 5, first, the antenna 1 is stopped with the antenna 1 attached to the support column 5 (step ST11). That is, by operating a wireless device connected to the antenna 1 or other equipment, transmission / reception of radio waves by the antenna 1 is stopped.

次に、アンテナ１を支持柱５から取り外し、より広い周波数帯に対応した別のアンテナ１を支持柱５に取り付けることにより、アンテナ１を交換する（ステップＳＴ１２）。アンテナ１を交換したら、新しく取り付けたアンテナ１に、無線装置と電気的に接続する電線を接続し、無線装置等の機器を操作することにより、アンテナ１を用いた電波の送受信を再開する（ステップＳＴ１３）。これにより、アンテナ１の交換時における停波の時間を極力短時間にしてアンテナ１の交換を完了させる。なお、このようにアンテナ１を交換した後、支持柱補強部材３０を取り付ける前の時点では、必要に応じて電線を容易に移動させることができるように、電線を束ねて支持柱５に仮止めするのが好ましい。   Next, the antenna 1 is removed from the support column 5, and another antenna 1 corresponding to a wider frequency band is attached to the support column 5, thereby exchanging the antenna 1 (step ST12). When the antenna 1 is replaced, the electric wire electrically connected to the wireless device is connected to the newly attached antenna 1 and the radio wave transmission / reception using the antenna 1 is resumed by operating a device such as the wireless device (step 1). ST13). This completes the exchange of the antenna 1 by shortening the wave-stopping time when exchanging the antenna 1 as much as possible. In addition, after replacing the antenna 1 in this manner and before attaching the support column reinforcing member 30, the wires are bundled and temporarily fixed to the support column 5 so that the wires can be easily moved as necessary. It is preferable to do this.

次に、壁面１０に補強部材取付部材７０用のアンカーボルト７６を設ける（ステップＳＴ１４）。壁面１０にアンカーボルト７６を設ける場合には、まず、支持柱５に対して下側補強金具４１を取り付ける位置を決める。この場合、下側補強金具４１を取り付ける位置は、支持柱５における壁面１０に対向している領域の範囲内で決める。例えば、支持柱５を壁面１０に取り付ける支持柱取付部材１１のうちの、上側取付部材１２の近傍における上側取付部材１２の下方側の位置を、下側補強金具４１を取り付ける位置として決める。支持柱５に対して下側補強金具４１を取り付ける位置を決めたら、下側補強金具４１を取り付ける位置に対向する壁面１０に、補強部材取付部材７０を取り付けるためのアンカーボルト７６を固定する。即ち、壁面１０におけるアンカーボルト７６を設ける部分にアンカーボルト７６用の穴をあけ、接着剤を用いてその穴にアンカーボルト７６を固定する。これにより、壁面１０に補強部材取付部材７０用のアンカーボルト７６を設ける。   Next, the anchor bolt 76 for the reinforcing member attachment member 70 is provided on the wall surface 10 (step ST14). When the anchor bolt 76 is provided on the wall surface 10, first, a position where the lower reinforcing metal fitting 41 is attached to the support column 5 is determined. In this case, the position where the lower reinforcing metal fitting 41 is attached is determined within the range of the region facing the wall surface 10 in the support column 5. For example, the position of the lower side of the upper mounting member 12 in the vicinity of the upper mounting member 12 in the supporting column mounting member 11 for mounting the support column 5 to the wall surface 10 is determined as the position for mounting the lower reinforcing metal fitting 41. When the position for attaching the lower reinforcing metal fitting 41 to the support column 5 is determined, the anchor bolt 76 for attaching the reinforcing member attaching member 70 is fixed to the wall surface 10 facing the position where the lower reinforcing metal fitting 41 is attached. That is, a hole for the anchor bolt 76 is formed in a portion of the wall surface 10 where the anchor bolt 76 is provided, and the anchor bolt 76 is fixed to the hole using an adhesive. Thereby, the anchor bolt 76 for the reinforcing member mounting member 70 is provided on the wall surface 10.

次に、補強部材取付部材７０の壁面取付部７３に形成される壁面取付穴７４にアンカーボルト７６を通し、アンカーボルト７６にナット７７を螺合させることにより、壁面１０に補強部材取付部材７０を取り付ける（ステップＳＴ１５）。壁面１０に補強部材取付部材７０を取り付けたら、支持柱５に上側補強金具３１と下側補強金具４１とを取り付ける（ステップＳＴ１６）。つまり、支持柱５における下側補強金具４１を取り付ける位置を、下側補強金具４１の第１部材４２と第２部材４３とで挟み込み、第１部材４２と第２部材４３とを補強金具取付ボルト６１とナット６２とで結合する。これにより、支持柱５における、壁面１０に補強部材取付部材７０が取り付けられている部分の近傍に下側補強金具４１を取り付ける。   Next, the anchor bolt 76 is passed through the wall surface mounting hole 74 formed in the wall surface mounting portion 73 of the reinforcing member mounting member 70, and the nut 77 is screwed into the anchor bolt 76, whereby the reinforcing member mounting member 70 is attached to the wall surface 10. Attach (step ST15). When the reinforcing member attaching member 70 is attached to the wall surface 10, the upper reinforcing metal member 31 and the lower reinforcing metal member 41 are attached to the support column 5 (step ST16). That is, the position at which the lower reinforcing metal fitting 41 is attached to the support pillar 5 is sandwiched between the first member 42 and the second member 43 of the lower reinforcing metal fitting 41, and the first member 42 and the second member 43 are attached to the reinforcing metal fitting mounting bolt. 61 and nut 62 are coupled. Thus, the lower reinforcing metal fitting 41 is attached in the vicinity of the portion of the support column 5 where the reinforcing member attaching member 70 is attached to the wall surface 10.

また、上側補強金具３１は、支持柱５における下側補強金具４１の上方の所望の取り付け位置に取り付ける。上側補強金具３１は、支持柱５に対して台風等によって大きな力が作用した場合に応力が大きくなる部分付近に設けることが好ましく、例えば、支持柱５の連結部７の近傍における連結部７の上方側に取り付ける。つまり、上側補強金具３１を取り付ける前の支持柱５では、応力は、支持柱５の頂部から上側取付部材１２の位置に向かって応力が大きくなるため、上側補強金具３１は、支持柱５の許容応力を超える部分よりも上方側の位置に取り付ける。支持柱５への上側補強金具３１の取り付けは、支持柱５への下側補強金具４１の取り付けと同様に、支持柱５を第１部材３２と第２部材３３とで挟み込み、第１部材３２と第２部材３３とを補強金具取付ボルト６１とナット６２とで結合する。これにより、支持柱５において応力が大きくなる部分より高い位置に上側補強金具３１を取り付ける。なお、上側補強金具３１を支持柱５に取り付ける際には、上側補強金具３１は、支持柱５の円周方向における補強棒鋼連結穴３７の位置が、同方向における下側補強金具４１の補強棒鋼連結穴４７の位置と同じ位置になる向きで取り付ける。   Further, the upper reinforcing metal fitting 31 is attached to a desired attachment position above the lower reinforcing metal fitting 41 in the support column 5. The upper reinforcing metal member 31 is preferably provided in the vicinity of a portion where stress is increased when a large force is applied to the support column 5 by a typhoon or the like. Install on the upper side. That is, in the support column 5 before the upper reinforcing bracket 31 is attached, the stress increases from the top of the support column 5 toward the position of the upper mounting member 12. It is attached at a position above the part exceeding the stress. As with the attachment of the lower reinforcement fitting 41 to the support column 5, the upper reinforcement fitting 31 is attached to the support column 5 by sandwiching the support column 5 between the first member 32 and the second member 33. And the second member 33 are coupled to each other by a reinforcing bracket mounting bolt 61 and a nut 62. As a result, the upper reinforcing metal fitting 31 is attached to a position higher than the portion of the support column 5 where the stress increases. When the upper reinforcing bracket 31 is attached to the support column 5, the upper reinforcing bracket 31 is positioned so that the reinforcing bar connecting hole 37 in the circumferential direction of the supporting column 5 has the reinforcing bar of the lower reinforcing bracket 41 in the same direction. Attach it in the same direction as the position of the connecting hole 47.

なお、これらの上側補強金具３１と下側補強金具４１との支持柱５への取り付けは、支持柱５に仮止めされている電線を必要に応じて移動させながら行ってもよい。   In addition, you may perform attaching to the support pillar 5 of these upper side reinforcement metal fittings 31 and the lower side reinforcement metal fitting 41, moving the electric wire temporarily fixed to the support pillar 5 as needed.

支持柱５に上側補強金具３１と下側補強金具４１とを取り付けたら、次に、下側補強金具４１と補強部材取付部材７０とを結合する（ステップＳＴ１７）。つまり、下側補強金具４１の取付部材取付部５０に形成される取付部材取付穴５１と、補強部材取付部材７０の補強金具取付部７１に形成される補強金具取付穴７２とに取付ボルト５５を通し、取付ボルト５５とナット５６を螺合する。これにより、下側補強金具４１と補強部材取付部材７０とを結合し、補強部材取付部材７０を介して下側補強金具４１を壁面１０に取り付ける。   After the upper reinforcing metal fitting 31 and the lower reinforcing metal fitting 41 are attached to the support column 5, the lower reinforcing metal fitting 41 and the reinforcing member attaching member 70 are then coupled (step ST17). That is, the mounting bolt 55 is attached to the mounting member mounting hole 51 formed in the mounting member mounting part 50 of the lower reinforcing metal fitting 41 and the reinforcing metal mounting hole 72 formed in the reinforcing metal mounting part 71 of the reinforcing member mounting member 70. Through, the mounting bolt 55 and the nut 56 are screwed together. Thus, the lower reinforcing metal fitting 41 and the reinforcing member attaching member 70 are coupled, and the lower reinforcing metal fitting 41 is attached to the wall surface 10 via the reinforcing member attaching member 70.

次に、上側補強金具３１及び下側補強金具４１と補強棒鋼６０とを連結する（ステップＳＴ１８）。つまり、上側補強金具３１の補強棒鋼連結部３６に形成される補強棒鋼連結穴３７と、下側補強金具４１の補強棒鋼連結部４６に形成される補強棒鋼連結穴４７とに、補強棒鋼６０の両端を差し込み、それぞれの端部に補強棒鋼連結用ナット６５を螺合することにより、補強棒鋼６０の両端を、上側補強金具３１と下側補強金具４１とに連結する。詳しくは、補強棒鋼連結用ナット６５は、補強棒鋼連結穴３７，４７に差し込んだ状態における、補強棒鋼連結部３６，４６の厚さ方向における両側に配設し、補強棒鋼連結部３６，４６の厚さ方向における両側から補強棒鋼連結部３６，４６を挟むように補強棒鋼連結用ナット６５を締め付ける。これにより、補強棒鋼６０の両端を、上側補強金具３１の補強棒鋼連結部３６と、下側補強金具４１の補強棒鋼連結部４６にそれぞれ連結する。   Next, the upper reinforcing metal member 31 and the lower reinforcing metal member 41 are connected to the reinforcing steel bar 60 (step ST18). That is, the reinforcing steel bar 60 is formed in the reinforcing steel bar connecting hole 37 formed in the reinforcing steel bar connecting part 36 of the upper reinforcing metal fitting 31 and the reinforcing steel bar connecting hole 47 formed in the reinforcing steel bar connecting part 46 of the lower reinforcing metal fitting 41. The both ends of the reinforcing bar 60 are connected to the upper reinforcing metal 31 and the lower reinforcing metal 41 by inserting both ends and screwing the reinforcing steel bar connecting nuts 65 into the respective ends. Specifically, the reinforcing steel bar connecting nuts 65 are disposed on both sides in the thickness direction of the reinforcing steel bar connecting parts 36 and 46 in a state of being inserted into the reinforcing steel bar connecting holes 37 and 47, and The reinforcing steel bar connecting nut 65 is tightened so as to sandwich the reinforcing steel bar connecting portions 36 and 46 from both sides in the thickness direction. As a result, both ends of the reinforcing steel bar 60 are connected to the reinforcing steel bar connecting part 36 of the upper reinforcing metal fitting 31 and the reinforcing bar steel connecting part 46 of the lower reinforcing metal fitting 41, respectively.

補強棒鋼６０を上側補強金具３１と下側補強金具４１とに連結したら、仮止めされていた電線を規定の位置に移動させてバンド等によって支持柱５に取り付ける。   When the reinforcing steel bar 60 is connected to the upper reinforcing metal fitting 31 and the lower reinforcing metal fitting 41, the temporarily fixed electric wire is moved to a specified position and attached to the support column 5 with a band or the like.

次に、支持柱５に取り付けられた支持柱補強部材３０の作用について説明する。支持柱５に取り付けられた支持柱補強部材３０は、支持柱５上において互いに離れた位置に配設される上側補強金具３１と下側補強金具４１が、複数の補強棒鋼６０によって連結されている。このため、支持柱５における上側補強金具３１と下側補強金具４１との間の範囲の曲げ剛性を、補強棒鋼６０の引張り剛性によって補うことができる。これにより、支持柱５の上端側に配設されるアンテナ１を、重量が重いものに交換することに伴い、アンテナ１に対して外力の入力があった際に支持柱５に対して大きな力が作用することになった場合に、この力を補強棒鋼６０でも受けることができる。   Next, the operation of the support column reinforcing member 30 attached to the support column 5 will be described. In the support column reinforcing member 30 attached to the support column 5, an upper reinforcing metal member 31 and a lower reinforcing metal member 41 disposed at positions separated from each other on the support column 5 are connected by a plurality of reinforcing steel bars 60. . For this reason, the bending rigidity of the support column 5 between the upper reinforcing metal 31 and the lower reinforcing metal 41 can be supplemented by the tensile rigidity of the reinforcing steel bar 60. Accordingly, when the antenna 1 disposed on the upper end side of the support column 5 is replaced with a heavy one, a large force is applied to the support column 5 when an external force is input to the antenna 1. This force can also be received by the reinforcing steel bar 60 in the case where the swaying force acts.

さらに、支持柱補強部材３０は、下側補強金具４１が補強部材取付部材７０を介して壁面１０に取り付けられているため、換言すると、支持柱補強部材３０は、補強部材取付部材７０によって壁面１０に取り付けられている。このため、支持柱補強部材３０は、支持柱５における壁面１０への取り付け部分の接合耐力も補うことができ、即ち、支持柱取付部材１１による、支持柱５の壁面１０への取り付け剛性を、支持柱補強部材３０によって補うことができる。これにより、支持柱５に対して大きな力が作用することにより、支持柱取付部材１１にも大きな力が作用した場合、この力を補強部材取付部材７０でも受けることができる。例えば、アンテナ１に対して大きな外力の入力があることにより、上側取付部材１２の部分での曲げモーメントが大きくなる状況でも、支持柱５の壁面１０に対する取り付け部分に作用する力を補強部材取付部材７０で受けて、取り付け部分に作用する力を分散することにより、曲げモーメントを小さくすることができる。   Further, the support column reinforcing member 30 has the lower reinforcing metal fitting 41 attached to the wall surface 10 via the reinforcing member mounting member 70. In other words, the support column reinforcing member 30 is attached to the wall surface 10 by the reinforcing member mounting member 70. Is attached. For this reason, the support column reinforcing member 30 can also compensate the joint strength of the mounting portion of the support column 5 to the wall surface 10, that is, the mounting rigidity of the support column 5 to the wall surface 10 by the support column mounting member 11, It can be supplemented by the support column reinforcing member 30. As a result, when a large force acts on the support column 5 and a large force acts on the support column mounting member 11, this force can also be received by the reinforcing member mounting member 70. For example, even when a bending moment at the portion of the upper mounting member 12 is increased due to the input of a large external force to the antenna 1, the force acting on the mounting portion of the support column 5 with respect to the wall surface 10 is increased. By receiving at 70 and dispersing the force acting on the mounting portion, the bending moment can be reduced.

従って、アンテナ１を重量が重いものに交換した後、例えば台風や大きな地震が発生することによってアンテナ１に大きな外力が作用した場合でも、支持柱５に対する曲げ方向の力を補強棒鋼６０でも受け、支持柱取付部材１１に作用する曲げモーメントを補強部材取付部材７０でも受けることができるため、アンテナ１を重量が重いものに交換した場合における支持柱５の耐力を向上させることができる。   Therefore, after replacing the antenna 1 with a heavy one, even if a large external force is applied to the antenna 1 due to, for example, a typhoon or a large earthquake, the reinforcing bar 60 receives the bending force on the support column 5. Since the bending moment acting on the support column attachment member 11 can also be received by the reinforcement member attachment member 70, the proof stress of the support column 5 when the antenna 1 is replaced with a heavy one can be improved.

以上の実施形態に係る支持柱補強部材３０は、支持柱５に取り付けられる上側補強金具３１と下側補強金具４１とを補強棒鋼６０で連結し、さらに、下側補強金具４１を補強部材取付部材７０によって壁面１０に取り付けるため、支持柱５に作用する力を、支持柱５が壁面１０に設置された状態で取り付ける補強棒鋼６０と補強部材取付部材７０とで受けることができる。この結果、アンテナ１を支持する支持柱５の補強を容易に行うことができる。   The support column reinforcing member 30 according to the above embodiment connects the upper reinforcing bracket 31 and the lower reinforcing bracket 41 attached to the supporting column 5 with the reinforcing steel bar 60, and further connects the lower reinforcing bracket 41 to the reinforcing member mounting member. 70, the force acting on the support column 5 can be received by the reinforcing bar 60 and the reinforcing member mounting member 70 that are mounted in a state where the support column 5 is installed on the wall surface 10. As a result, the support column 5 that supports the antenna 1 can be easily reinforced.

また、上側補強金具３１と下側補強金具４１とは、それぞれ第１部材３２，４２と第２部材３３，４３とで支持柱５を挟み込み、第１部材３２，４２と第２部材３３，４３とを結合することにより支持柱５に取り付けるため、壁面１０に設置されている状態の支持柱５に対して、容易に取り付けることができる。この結果、支持柱５の補強を、より確実に容易に行うことができる。   Further, the upper reinforcing metal fitting 31 and the lower reinforcing metal fitting 41 sandwich the support pillar 5 between the first members 32 and 42 and the second members 33 and 43, respectively, and the first members 32 and 42 and the second members 33 and 43 are sandwiched therebetween. Since it attaches to the support pillar 5 by combining, it can attach easily with respect to the support pillar 5 of the state installed in the wall surface 10. FIG. As a result, the support column 5 can be reinforced more easily and reliably.

また、上側補強金具３１と下側補強金具４１とは、支持柱５の延在方向における上側取付部材１２の両側の位置に取り付けられているため、アンテナ１に外力が入力されることによって上側取付部材１２が取り付けられている部分付近に作用する力を上側補強金具３１及び下側補強金具４１と補強棒鋼６０とで分散することができる。さらに、上側取付部材１２の両側に上側補強金具３１と下側補強金具４１とを配設し、補強部材取付部材７０を介して下側補強金具４１を壁面１０に取り付けることにより、上側取付部材１２に作用する曲げモーメントを小さくすることができる。これらの結果、支持柱５の補強を、より確実に行うことができる。   Further, since the upper reinforcing metal fitting 31 and the lower reinforcing metal fitting 41 are attached to positions on both sides of the upper attachment member 12 in the extending direction of the support column 5, the upper attachment is made by inputting external force to the antenna 1. The force acting in the vicinity of the portion where the member 12 is attached can be distributed between the upper reinforcing bracket 31, the lower reinforcing bracket 41 and the reinforcing bar 60. Further, the upper reinforcing member 31 and the lower reinforcing member 41 are disposed on both sides of the upper attaching member 12, and the lower reinforcing member 41 is attached to the wall surface 10 via the reinforcing member attaching member 70, whereby the upper attaching member 12. The bending moment that acts on can be reduced. As a result, the support column 5 can be reinforced more reliably.

また、支持柱補強部材３０は、補強部材取付部材７０が、壁面１０における上側取付部材１２と下側取付部材１７との間に取り付けられるため、壁面１０に対する取り付け領域を大きくすることなく壁面１０に取り付けることができる。このため、建物の壁面１０を借りてアンテナ１を設置しているような場合でも、占有面積が大きくなることを抑制することができ、壁面１０を借りる際における賃料の増加等を抑えることができる。   Further, since the reinforcing member attaching member 70 is attached between the upper attaching member 12 and the lower attaching member 17 on the wall surface 10, the support column reinforcing member 30 is attached to the wall surface 10 without increasing the attachment region with respect to the wall surface 10. Can be attached. For this reason, even when the antenna 1 is installed by borrowing the wall 10 of the building, it is possible to suppress an increase in the occupied area, and it is possible to suppress an increase in rent when the wall 10 is rented. .

また、支持柱補強部材３０は、アンテナ１を重量が重いものや受風面積が大きくなるものに交換する際に、元々設置されている支持柱５に対して取り付けることによって補強を行うため、アンテナ１の交換と合わせて、支持柱５もアンテナ１の重量に応じたものに交換する場合と比較して、アンテナ１の交換時に発生する費用を抑えることができる。この結果、アンテナ１の交換を低コストで行うことができる。   Further, the support pillar reinforcing member 30 reinforces the antenna 1 by attaching it to the support pillar 5 that is originally installed when the antenna 1 is replaced with one having a heavy weight or a large wind receiving area. In addition to the replacement of 1, compared with the case where the support pillar 5 is replaced with one corresponding to the weight of the antenna 1, the cost generated when the antenna 1 is replaced can be suppressed. As a result, the antenna 1 can be replaced at a low cost.

また、支持柱補強部材３０の取り付け作業は、支持柱５の交換作業と比較して短時間で行うことができるため、アンテナ１の交換時の停波の時間を短くすることができる。この結果、移動無線端末の基地局として運用を停止する時間を短くすることができ、アンテナ１の交換に伴う、移動無線端末の基地局に対する影響を小さくすることができる。   In addition, since the mounting work of the support column reinforcing member 30 can be performed in a short time compared to the replacement work of the support column 5, it is possible to shorten the wave stopping time when the antenna 1 is replaced. As a result, it is possible to shorten the operation stop time as a base station of the mobile radio terminal, and to reduce the influence on the base station of the mobile radio terminal due to the replacement of the antenna 1.

また、支持柱補強部材３０は、壁面１０への補強部材取付部材７０の取り付け、支持柱５への上側補強金具３１と下側補強金具４１と取り付け、下側補強金具４１と補強部材取付部材７０との結合、上側補強金具３１及び下側補強金具４１と補強棒鋼６０との連結を、全てボルトやナットを用いて行うため、工事品質のバラつきを低減することができる。この結果、アンテナ１の交換に伴う支持柱５の補強を、安全に高品質で行うことができる。   In addition, the support column reinforcing member 30 is mounted on the wall surface 10 with the reinforcing member mounting member 70, mounted on the support column 5 with the upper reinforcing bracket 31 and the lower reinforcing bracket 41, and the lower reinforcing bracket 41 and the reinforcing member mounting member 70. And the connection between the upper reinforcement fitting 31 and the lower reinforcement fitting 41 and the reinforcing steel bar 60 are all performed using bolts and nuts, so that variations in construction quality can be reduced. As a result, it is possible to reinforce the support column 5 accompanying the replacement of the antenna 1 safely and with high quality.

また、上側補強金具３１や下側補強金具４１は、支持柱５を挟み込むことによって支持柱５に取り付けるので、同一の部材で取り付けることのできる支持柱５のサイズの範囲を大きくすることができる。図１２は、実施形態に係る支持柱補強部材の変形例であり、支持柱の直径が実施形態のものよりも大きい場合における上側補強金具の説明図である。上側補強金具３１や下側補強金具４１は、所定の大きさの支持柱５に合わせたものではないため、支持柱５の大きさに関わらず支持柱５に取り付けることができる。例えば、図１２に示すように、支持柱５の直径が実施形態における支持柱５の直径より大きい場合であっても、補強金具取付ボルト６１を長くすることのみで、実施形態における上側補強金具３１と同じ上側補強金具３１を、直径が大きい支持柱５に取り付けることができる。従って、上側補強金具３１や下側補強金具４１を、支持柱５の大きさに合わせて製造する必要がなくなるため、支持柱補強部材３０の製造コストを抑えることができ、アンテナ１の交換を、より確実に低コストで行うことができる。   Moreover, since the upper side reinforcement metal fitting 31 and the lower side reinforcement metal fitting 41 are attached to the support pillar 5 by pinching the support pillar 5, the range of the size of the support pillar 5 which can be attached with the same member can be enlarged. FIG. 12 is a modified example of the support column reinforcing member according to the embodiment, and is an explanatory view of the upper reinforcing metal fitting when the diameter of the support column is larger than that of the embodiment. Since the upper reinforcing bracket 31 and the lower reinforcing bracket 41 are not adapted to the support pillar 5 having a predetermined size, they can be attached to the support pillar 5 regardless of the size of the support pillar 5. For example, as shown in FIG. 12, even if the diameter of the support column 5 is larger than the diameter of the support column 5 in the embodiment, the upper reinforcing metal member 31 in the embodiment can be obtained only by lengthening the reinforcement metal fitting bolt 61. The same upper reinforcing metal fitting 31 can be attached to the support pillar 5 having a large diameter. Accordingly, since it is not necessary to manufacture the upper reinforcing metal fitting 31 and the lower reinforcing metal fitting 41 according to the size of the support pillar 5, the manufacturing cost of the support pillar reinforcing member 30 can be suppressed, and the antenna 1 can be replaced. It can be carried out more reliably at low cost.

〔変形例〕
なお、上述した実施形態では、上側補強金具３１は、支持柱５の連結部７の近傍における連結部７の上側に取り付けているが、上側補強金具３１は、連結部７の近傍以外の部分に取り付けてもよい。上側補強金具３１は、連結部７との相対位置に関わらず、台風等によって支持柱５に対して外部から力が入力された際に、応力が大きくなる領域の上側に取り付けるのが好ましい。 [Modification]
In the embodiment described above, the upper reinforcing metal fitting 31 is attached to the upper side of the connecting portion 7 in the vicinity of the connecting portion 7 of the support column 5, but the upper reinforcing metal fitting 31 is attached to a portion other than the vicinity of the connecting portion 7. It may be attached. Regardless of the relative position with respect to the connecting portion 7, the upper reinforcing metal member 31 is preferably attached to the upper side of a region where stress is increased when a force is input from the outside to the support column 5 by a typhoon or the like.

また、上述した実施形態では、上側補強金具３１と下側補強金具４１とは、補強金具取付ボルト６１とナット６２とによって支持柱５に取り付けられているが、上側補強金具３１や下側補強金具４１の、支持柱５への取り付け強度が不足している場合には、補強金具取付ボルト６１とナット６２以外のものを用いてもよい。支持柱５への上側補強金具３１や下側補強金具４１の取り付け強度が、補強金具取付ボルト６１とナット６２による取り付けのみでは不足している場合は、例えば接着剤を併用してもよい。つまり、上側補強金具３１や下側補強金具４１と支持柱５との接触面に、接着剤を塗布した上で補強金具取付ボルト６１とナット６２とを用いて取り付けを行ってもよい。これにより、上側補強金具３１や下側補強金具４１を、より確実に支持柱５に取り付けることができ、支持柱５の補強を、より確実に行うことができる。   In the above-described embodiment, the upper reinforcing bracket 31 and the lower reinforcing bracket 41 are attached to the support column 5 by the reinforcing bracket mounting bolt 61 and the nut 62. When the mounting strength of 41 to the support pillar 5 is insufficient, a member other than the reinforcing bracket mounting bolt 61 and the nut 62 may be used. If the mounting strength of the upper reinforcing bracket 31 and the lower reinforcing bracket 41 to the support column 5 is insufficient only by mounting with the reinforcing bracket mounting bolt 61 and the nut 62, for example, an adhesive may be used together. In other words, the adhesive may be applied to the contact surfaces of the upper reinforcing metal 31 or the lower reinforcing metal 41 and the support column 5 and then attached using the reinforcing metal mounting bolts 61 and the nuts 62. Thereby, the upper side reinforcement metal fitting 31 and the lower side reinforcement metal fitting 41 can be more reliably attached to the support pillar 5, and the reinforcement of the support pillar 5 can be performed more reliably.

また、アンテナ１及び支持柱５は、建物の壁面１０以外に取り付けられていてもよく、即ち、支持柱補強部材は、建物の壁面１０に取り付けられる支持柱５以外の支持柱を補強するように構成されていてもよい。図１３は、実施形態に係る支持柱補強部材の変形例であり、建物の屋上に設置されるアンテナの支持柱を補強する支持柱補強部材についての説明図である。支持柱補強部材１００は、例えば、図１３に示すように、建物の屋上９０に設置されるアンテナ１の支持柱８０に取り付けられて支持柱８０の補強を行うものであってもよい。この場合、支持柱８０は、建物に屋上９０に設置されるアンテナ基礎９１に下端側が取り付けられ、アンテナ基礎９１から上方に延びる向きで配設されることにより、長さ方向が略鉛直方向になる向きで屋上９０に設置される。詳しくは、支持柱８０は、アンテナ基礎９１の上面に設けられるアンカーボルト９２に、支持柱８０の下端に設けられるベースプレート８１を挟んでナット９３を螺合することにより、アンテナ基礎９１から上方に延びる向きでアンテナ基礎９１に取り付けられる。支持柱８０によって支持するアンテナ１は、上述した実施形態に係る支持柱補強部材３０が取り付けられる支持柱５で支持するアンテナ１と同様に、支持柱８０の上端寄りの位置に取り付けられており、支持柱５の上端には、避雷針８２が配設されている。   The antenna 1 and the support column 5 may be attached to other than the wall surface 10 of the building, that is, the support column reinforcing member reinforces the support column other than the support column 5 attached to the wall surface 10 of the building. It may be configured. FIG. 13 is a modified example of the support column reinforcing member according to the embodiment, and is an explanatory view of the support column reinforcing member that reinforces the support column of the antenna installed on the roof of the building. For example, as shown in FIG. 13, the support column reinforcing member 100 may be attached to the support column 80 of the antenna 1 installed on the roof 90 of the building to reinforce the support column 80. In this case, the support pillar 80 is attached to the antenna base 91 installed on the rooftop 90 in the building, and is arranged in a direction extending upward from the antenna base 91, so that the length direction becomes a substantially vertical direction. It is installed on the rooftop 90 in the direction. Specifically, the support column 80 extends upward from the antenna base 91 by screwing a nut 93 with an anchor bolt 92 provided on the upper surface of the antenna base 91 sandwiching a base plate 81 provided at the lower end of the support column 80. It is attached to the antenna base 91 in the direction. The antenna 1 supported by the support pillar 80 is attached at a position near the upper end of the support pillar 80, similarly to the antenna 1 supported by the support pillar 5 to which the support pillar reinforcing member 30 according to the above-described embodiment is attached. A lightning rod 82 is disposed at the upper end of the support column 5.

このように屋上９０に設置される支持柱８０に取り付けられる支持柱補強部材１００は、上述した実施形態に係る支持柱補強部材３０と同様に、上側補強金具１０１と下側補強金具１１１とを有している。上側補強金具１０１は、上述した実施形態に係る支持柱補強部材３０が有する上側補強金具３１と同様の形態で構成されており、第１部材１０２と第２部材１０３とを有している。上側補強金具１０１は、第１部材１０２と第２部材１０３とで支持柱８０を挟み込んだ状態で第１部材１０２と第２部材１０３とを結合することにより、支持柱８０に取り付けられる。また、下側補強金具１１１は、上側補強金具１０１と同じ形状で形成されており、第１部材１１２と第２部材１１３とを有している。下側補強金具１１１は、上側補強金具１０１と同様に、第１部材１１２と第２部材１１３とで支持柱８０を挟み込んだ状態で第１部材１１２と第２部材１１３とを結合することにより、支持柱８０に取り付けられる。   As described above, the support column reinforcing member 100 attached to the support column 80 installed on the roof 90 includes the upper side reinforcing metal fitting 101 and the lower side reinforcing metal fitting 111, similarly to the support column reinforcing member 30 according to the above-described embodiment. doing. The upper reinforcing metal fitting 101 is configured in the same form as the upper reinforcing metal fitting 31 included in the support column reinforcing member 30 according to the above-described embodiment, and includes a first member 102 and a second member 103. The upper reinforcing metal fitting 101 is attached to the support pillar 80 by joining the first member 102 and the second member 103 with the support pillar 80 sandwiched between the first member 102 and the second member 103. Further, the lower reinforcing metal fitting 111 is formed in the same shape as the upper reinforcing metal fitting 101, and includes a first member 112 and a second member 113. Similarly to the upper reinforcing metal fitting 101, the lower reinforcing metal fitting 111 combines the first member 112 and the second member 113 with the support column 80 sandwiched between the first member 112 and the second member 113. Attached to the support column 80.

つまり、上側補強金具１０１と下側補強金具１１１とは、同じ形状のものが用いられ、相対的に上側補強金具１０１が下側補強金具１１１よりも支持柱８０における上側の位置に取り付けられ、下側補強金具１１１が上側補強金具１０１よりも支持柱８０における下側の位置に取り付けられる。これらの上側補強金具１０１と下側補強金具１１１とには、上述した実施形態に係る支持柱補強部材３０と同様に、補強棒鋼１２０が連結される。即ち、補強棒鋼１２０は、複数が用いられ、それぞれ上端側が上側補強金具１０１に連結され、下端側が下側補強金具１１１に連結される。   That is, the upper reinforcing metal fitting 101 and the lower reinforcing metal fitting 111 are of the same shape, and the upper reinforcing metal fitting 101 is relatively attached to the upper position of the support column 80 relative to the lower reinforcing metal fitting 111, and The side reinforcing bracket 111 is attached to a lower position in the support column 80 than the upper reinforcing bracket 101. A reinforcing bar 120 is connected to the upper reinforcing metal fitting 101 and the lower reinforcing metal fitting 111 in the same manner as the support column reinforcing member 30 according to the above-described embodiment. That is, a plurality of reinforcing steel bars 120 are used, each having an upper end connected to the upper reinforcing metal fitting 101 and a lower end connected to the lower reinforcing metal fitting 111.

これらのように、建物の屋上９０に設置される支持柱８０に取り付けられる支持柱補強部材１００も、台風等によって支持柱８０に対して大きな力が作用した場合に、支持柱８０において応力が大きくなる部分を、支持柱８０に長さ方向において挟む位置に、上側補強金具１０１と下側補強金具１１１とを取り付けるのが好ましい。これにより、建物の屋上９０に設置される支持柱８０のアンテナ１を、重量が重いものに交換する場合でも、支持柱８０は交換することなく、支持柱８０に対して支持柱補強部材１００を取り付けるのみで強度を確保することができるため、低コストでアンテナ１の交換を行うことができる。支持柱補強部材によって補強を行うアンテナ１の支持柱は、これらのように、建物の壁面１０に設置されるもの以外であってもよく、アンテナ１を支持することができ、一方向の延びる支持柱であれば、その設置形態は問わない。   As described above, the support column reinforcing member 100 attached to the support column 80 installed on the roof 90 of the building also has a large stress in the support column 80 when a large force acts on the support column 80 due to a typhoon or the like. It is preferable to attach the upper reinforcing metal fitting 101 and the lower reinforcing metal fitting 111 at a position where the portion to be sandwiched between the support pillars 80 in the length direction. Accordingly, even when the antenna 1 of the support column 80 installed on the roof 90 of the building is replaced with a heavy one, the support column reinforcing member 100 is attached to the support column 80 without replacing the support column 80. Since strength can be ensured only by mounting, the antenna 1 can be replaced at low cost. The support column of the antenna 1 that is reinforced by the support column reinforcing member may be other than those installed on the wall surface 10 of the building as described above, and can support the antenna 1 and support in one direction. If it is a pillar, the installation form is not ask | required.
