Description

本発明は、斜材にかかる荷重を肩代わりすることにより当該斜材の交換を可能にする鉄塔の斜材交換装置に関する。   The present invention relates to an oblique member exchanging apparatus for a steel tower that allows the oblique member to be replaced by taking over the load applied to the oblique member.

通常、鉄塔は、所定の間隔をおいて立設された例えば4基の主柱材と、これらの各主柱材を連結する水平材や斜材等の腹材と、その他の種々の構成部材とを備えたもので構成されている。このような鉄塔においては、架空線等からの外力を受けることにより、水平材や斜材には、引張荷重や圧縮荷重が作用することになる。このため、例えば所定の斜材を交換するためには、当該斜材に作用する荷重を所定の部材で肩代わりすることが必要であり、そのために斜材交換装置が必要になる。   Usually, a steel tower is composed of, for example, four main pillars erected at predetermined intervals, abdominal materials such as horizontal members and diagonal members that connect these main pillar members, and various other components. It is comprised with what. In such a steel tower, a tensile load or a compressive load acts on the horizontal member and the diagonal member by receiving an external force from an overhead wire or the like. For this reason, for example, in order to replace a predetermined diagonal member, it is necessary to replace the load acting on the diagonal member with a predetermined member, and for that purpose, an oblique member replacement device is required.

この種の斜材交換装置としては、例えば間隔をおいて配置された一方及び他方の主柱材のそれぞれに取り付けるバンドと、これらのバンドに連結部材等を介して連結された油圧ジャッキとを備えたものが知られている(例えば特許文献1)。   This type of diagonal material exchanging device includes, for example, a band attached to each of one and the other main pillar members arranged at intervals, and a hydraulic jack connected to these bands via a connecting member or the like. Are known (for example, Patent Document 1).

上記バンドは、主柱材を挟みつける二枚の当接板を備えており、これらの当接板を互いに近接する方向にボルトで締め付けることで、主柱材に固定するようになっている。即ち、各バンドは、当接板で主柱材を圧迫することで生じる摩擦力を利用して当該主柱材の任意の位置に固定することが可能になっている。   The band includes two contact plates that sandwich the main pillar material, and is fixed to the main pillar material by tightening these contact plates with bolts in directions close to each other. That is, each band can be fixed at an arbitrary position of the main column member by using a frictional force generated by pressing the main column member with the contact plate.

上記のように構成された斜材交換装置においては、各バンドを一方及び他方の主柱材の任意の位置に固定することができるので、交換しようとする所定の斜材に沿うように、油圧ジャッキ等を設置することができる。このため、油圧ジャッキに荷重を発生させることで、斜材に作用する荷重を当該油圧ジャッキで肩代わりすることができ、これにより当該斜材に作用する荷重を除去することができるので、当該斜材を容易に交換することができる。交換した後は、油圧ジャッキに作用する荷重を取り除いてから、油圧ジャッキや各バンド等を主柱材から取り外すことになる。   In the diagonal material exchanging apparatus configured as described above, each band can be fixed at an arbitrary position on one and the other main pillar materials, so that the hydraulic pressure is adjusted so as to follow the predetermined diagonal material to be replaced. A jack etc. can be installed. For this reason, by generating a load on the hydraulic jack, it is possible to replace the load acting on the diagonal member with the hydraulic jack, thereby removing the load acting on the diagonal member. Can be easily replaced. After the replacement, the load acting on the hydraulic jack is removed, and then the hydraulic jack and each band are removed from the main pillar material.

また、上記斜材交換装置においては、油圧ジャッキ等が全体的に長尺のもので構成されていることから、圧縮荷重を発生させた場合には座屈の危険性がある。このため、引張荷重を発生させることにより、斜材に作用する荷重を取り除くことになる。例えば、所定の斜材に引張荷重が作用している場合にはこれに交差する方向の斜材に圧縮荷重が作用することになるが、引張荷重の作用している斜材からその引張荷重を除去する方向の力を作用させることにより、これに交差する方向の斜材の圧縮荷重も除去することができる。従って、上記斜材交換装置を用いることで、圧縮荷重の作用している斜材についても交換することができる。   Further, in the above-described oblique member exchanging apparatus, since the hydraulic jack or the like is formed of a long one as a whole, there is a risk of buckling when a compressive load is generated. For this reason, the load which acts on a diagonal is removed by generating a tensile load. For example, when a tensile load is applied to a predetermined diagonal material, a compressive load will be applied to the diagonal material in the direction intersecting this, but the tensile load is applied from the diagonal material acting on the tensile load. By applying a force in the removing direction, it is possible to remove the compressive load of the diagonal material in the direction intersecting the force. Therefore, by using the diagonal material exchanging device, it is possible to replace the diagonal material on which the compressive load is applied.

しかし、上記斜材交換装置においては、各バンドが単に摩擦力によって主柱材に固定されているだけであることから、油圧ジャッキからバンドに作用する荷重の大きさによっては当該バンドが主柱材の延在する方向(以下「軸方向」という。)に滑るおそれがある。例えば、突風等に起因する想定を超えるような大きさの外力が鉄塔に作用した場合には、バンド(即ち、斜材交換装置における摩擦力を利用して主柱材に連結する端部)が主柱材の軸方向に移動するおそれがあった。   However, in the oblique material exchanging device, each band is simply fixed to the main column member by a frictional force, and therefore, depending on the magnitude of the load acting on the band from the hydraulic jack, the band may be the main column member. There is a risk of slipping in the extending direction (hereinafter referred to as “axial direction”). For example, when an external force of a magnitude exceeding the assumption caused by gusts or the like acts on the steel tower, the band (that is, the end connected to the main column member using the frictional force in the slanting material exchanging device) There was a risk of moving in the axial direction of the main pillar.

請求項1に記載の発明によれば、引張荷重を受ける第1の斜材の一端部が下方に位置する場合には当該第1の斜材の一端部の下側における一方の主柱材に第1挟持部材を取り付け、当該第1の斜材の他端部の下側における他方の主柱材に第2挟持部材を取り付け、かつ当該第2挟持部材の例えば下側における他方の主柱材に第3挟持部材を取り付ける。   According to the first aspect of the present invention, when one end portion of the first diagonal member receiving the tensile load is positioned below, the one main column member on the lower side of the one end portion of the first diagonal member is provided. A first clamping member is attached, a second clamping member is attached to the other main pillar material on the lower side of the other end of the first diagonal member, and the other main pillar material on the lower side of the second clamping member, for example. A third clamping member is attached to

この際、第1挟持部材は、第1の斜材の一端部を一方の主柱材に対して着脱自在に連結するために当該一方の主柱材に設けられている例えばガセットプレートの下縁に近接あるいは接するようにして、当該一方の主柱材に圧迫固定する。   At this time, the first clamping member is, for example, a lower edge of the gusset plate provided on the one main column member in order to detachably connect one end portion of the first diagonal member to the one main column member. It is pressed and fixed to the one main pillar material so as to be close to or in contact with the main pillar material.

一方、第2挟持部材は、第1の斜材の他端部を他方の主柱材に対して着脱自在に連結するために当該他方の主柱材に設けられている例えばガセットプレートの下縁近傍となるようにして、当該他方の主柱材に仮に圧迫固定する。   On the other hand, the second clamping member is, for example, a lower edge of the gusset plate provided on the other main column member in order to detachably connect the other end portion of the first diagonal member to the other main column member. Temporarily press and fix to the other main pillar material so as to be in the vicinity.

また、第3挟持部材は、第1の斜材に交差する第2の斜材の下方の端部を他方の主柱材に対して着脱自在に連結するために当該他方の主柱材に設けられている例えばガセットプレートの上縁に近接あるいは接するようにして、当該他方の主柱材に圧迫固定する。   The third clamping member is provided on the other main column member so as to detachably connect the lower end portion of the second oblique member intersecting the first oblique member to the other main column member. For example, it is pressed and fixed to the other main column member so as to be close to or in contact with the upper edge of the gusset plate.

そして、第2挟持部材と第3挟持部材とを間隔維持部材で連結する。この際、第2挟持部材が第1の斜材の他端部を支持するガセットプレートにできる限り接近した状態となるように間隔維持部材と第2挟持部材及び第3挟持部材との連結位置を調整してから、当該第2挟持部材を他方の主柱材に正規に圧迫固定する。   And a 2nd clamping member and a 3rd clamping member are connected with a space | interval maintenance member. At this time, the connecting position between the spacing member, the second clamping member, and the third clamping member is set so that the second clamping member is as close as possible to the gusset plate that supports the other end of the first diagonal member. After the adjustment, the second holding member is normally pressed and fixed to the other main pillar material.

更に、連結部材群を、第1挟持部材と第2挟持部材とを連結するように設置する。この際の連結は、伸縮量調整部材の長さを伸縮調整することで、連結部材群の全長を第1挟持部材と第2挟持部材との間の寸法に合わせることができることから、簡単に行うことができる。これにより、各連結部材及び伸縮量調整部材が第1の斜材に沿って延在する状態になる。   Further, the connecting member group is installed so as to connect the first holding member and the second holding member. The connection at this time is easily performed because the overall length of the connecting member group can be adjusted to the dimension between the first and second clamping members by adjusting the length of the expansion / contraction amount adjusting member. be able to. Thereby, each connection member and the expansion-contraction amount adjustment member will be in the state extended along the 1st diagonal.

以上により、斜材交換装置を鉄塔に設置した状態において、伸縮量調整部材の長さを漸次縮減することにより、各連結部材及び伸縮量調整部材に引張荷重が徐々に発生することになる。これにより、第1の斜材に作用していた引張荷重が徐々に減少するので、当該第1の斜材の引張荷重が零になった時点で伸縮量調整部材による長さの減縮を停止する。この第1の斜材の引張荷重が零になる時点は、当該第1の斜材をガセットプレートに固定する例えばボルトがそのボルト挿通孔に対して移動自在となることから、簡単にかつ確実に確認することができる。そこで、第1の斜材を新たなものに交換する。   As described above, in the state in which the diagonal member exchanging device is installed on the steel tower, by gradually reducing the length of the expansion / contraction amount adjusting member, a tensile load is gradually generated in each connecting member and the expansion / contraction amount adjusting member. As a result, the tensile load acting on the first diagonal member gradually decreases, and therefore the length reduction by the expansion / contraction amount adjusting member is stopped when the tensile load of the first diagonal member becomes zero. . When the tensile load of the first diagonal member becomes zero, for example, a bolt for fixing the first diagonal member to the gusset plate is movable with respect to the bolt insertion hole. Can be confirmed. Therefore, the first diagonal member is replaced with a new one.

第2の斜材については、伸縮量調整部材の長さを更に減縮調整し、当該第2の斜材の圧縮荷重が零になるのを確認してから、当該第2の斜材を新たなものに交換する。   For the second diagonal member, the length of the expansion / contraction amount adjusting member is further reduced and adjusted, and after confirming that the compression load of the second diagonal member becomes zero, the second diagonal member is replaced with a new one. Replace with something.

なお、第1の斜材を取り外した後、新たな第1の斜材を取り付ける前に、第2の斜材が交換可能な状態になるように伸縮量調整部材の長さを調整して当該第2の斜材を新たなものに交換し、その後再び第1の斜材が交換可能な状態になるように伸縮量調整部材の長さを調整した上で、新たな第1の斜材を取り付けるようにしてもよい。   After removing the first diagonal member and before attaching a new first diagonal member, the length of the expansion / contraction amount adjusting member is adjusted so that the second diagonal member is replaceable. Replace the second diagonal with a new one, and then adjust the length of the expansion / contraction adjustment member so that the first diagonal can be replaced again. You may make it attach.

第1の斜材及び第2の斜材を交換した後は、伸縮量調整部材を伸長する調整をして、当該伸縮量調整部材に作用する引張荷重を完全に除去した後、伸縮量調整部材を含む連結部材群の全体を第1挟持部材及び第2挟持部材から取り外すことになる。また、第1挟持部材、第2挟持部材、第3挟持部材及び間隔維持部材については、そのまま各主柱材から取り外すか、当該各主柱材における他の部位に移動し、他の第1の斜材等の交換に供することになる。   After exchanging the first diagonal member and the second diagonal member, the expansion / contraction amount adjusting member is adjusted to extend, and after the tensile load acting on the expansion / contraction amount adjusting member is completely removed, the expansion / contraction amount adjusting member The whole of the connecting member group including is removed from the first holding member and the second holding member. In addition, the first clamping member, the second clamping member, the third clamping member, and the interval maintaining member are removed from the main pillar materials as they are or moved to other parts of the main pillar materials, and the other first It will be used for replacement of diagonal materials.

以上のように作業することにより、引張荷重の作用する第1の斜材及び圧縮荷重の作用する第2の斜材を、新たなものに簡単に交換することができる。   By working as described above, the first diagonal member acting on the tensile load and the second diagonal member acting on the compressive load can be easily replaced with new ones.

また、第1挟持部材及び第2挟持部材は各主柱材の外面を圧迫することによる摩擦力を利用して当該各主柱材に固定しているので、突風等による想定を超える大きさの外力が鉄塔に作用した場合には、各主柱材に連結する端部である第1挟持部材及び第2挟持部材が当該各主柱材に沿って移動するおそれがある。即ち、第1の斜材や第2の斜材は主柱材に対してほぼ45度の方向に延在する場合が多く、各連結部材及び伸縮量調整部材もその角度方向とほぼ同じ方向に延在することになることから、想定外の大きさの外力が鉄塔に作用すると、各連結部材及び伸縮量調整部材に発生する引張荷重のうち各主柱材の軸方向の分力が想定を超える大きさになり、第1挟持部材又は第2挟持部材が各主柱材に沿って滑るおそれがある。   In addition, since the first clamping member and the second clamping member are fixed to each main column member by using frictional force generated by pressing the outer surface of each main column member, the size of the first clamping member and the second clamping member is larger than expected due to gusts or the like. When an external force acts on the steel tower, there is a possibility that the first clamping member and the second clamping member, which are ends connected to the main pillar members, move along the main pillar members. In other words, the first diagonal member and the second diagonal member often extend in a direction of approximately 45 degrees with respect to the main column member, and each connecting member and the expansion / contraction amount adjusting member are also substantially in the same direction as the angular direction. Therefore, when an external force of an unexpected magnitude acts on the steel tower, the axial component force of each main column member is assumed among the tensile loads generated on each connecting member and the expansion / contraction amount adjusting member. There is a possibility that the first clamping member or the second clamping member may slide along each main pillar material.

この場合、連結部材群から第1挟持部材に作用する分力は、当該第1挟持部材を一方の主柱材の軸方向上方に作用する力となる。また、連結部材群から第2挟持部材に作用する分力は、当該第2挟持部材を他方の主柱材の軸方向下方に作用する力となる。   In this case, the component force that acts on the first clamping member from the connecting member group is the force that acts on the first clamping member in the axial direction above one main column member. Moreover, the component force which acts on the 2nd clamping member from a connection member group turns into the force which acts on the said 2nd clamping member to the axial direction downward direction of the other main pillar material.

しかし、第1挟持部材については、上述したガセットプレートの下縁に近接あるいは接するように取り付けることができるので、一方の主柱材との間の摩擦力を超える分力が当該主柱材の軸方向の上方に作用したとしても、上方に滑り移動するのを確実に防止することができる。   However, since the first clamping member can be attached so as to be close to or in contact with the lower edge of the gusset plate described above, the component force exceeding the frictional force with one of the main column members is the axis of the main column member. Even if it acts upward in the direction, it can be reliably prevented from sliding upward.

一方、第2挟持部材は、他方の主柱材との間の摩擦力を超える分力が当該主柱材の軸方向の下方に作用したとしても、その摩擦力を超える力の成分が間隔維持部材を介して第3挟持部材に伝えられることになるので、その力の成分が第3挟持部材における他方の主柱材との間の摩擦力を超えなければ、当該主柱材の軸方向の下方に移動することがない。また、上記力の成分が第3挟持部材と他方の主柱材との間の摩擦力を超える大きさになったとしても、第3挟持部材を上述したガセットプレートの上縁に近接あるいは接するように取り付けることができるので、当該第3挟持部材が下方に滑り移動するのを確実に防止することができ、よって第2挟持部材も下方に移動するのを確実に防止することができる。   On the other hand, even if the component force exceeding the friction force between the other main pillar material acts on the lower side of the second pillar member in the axial direction of the main pillar material, the component of the force exceeding the friction force maintains the interval. Since the force component is transmitted to the third sandwiching member via the member, the axial component of the main pillar member in the axial direction is not required unless the force component exceeds the frictional force between the third sandwiching member and the other main pillar member. It does not move downward. Further, even if the force component exceeds the frictional force between the third clamping member and the other main column member, the third clamping member is brought close to or in contact with the upper edge of the gusset plate. Therefore, it is possible to reliably prevent the third holding member from sliding down, and thus it is possible to reliably prevent the second holding member from moving downward.

なお、上記説明では、引張荷重が作用する第1の斜材の一端部が一方の主柱材にあって下方に位置し、当該第1の斜材の他端部が他方の主柱材にあって上方に位置する場合における当該第1の斜材及び第2の斜材を交換する際の手順及び効果を示した。しかし、第1の斜材の一端部が一方の主柱材にあって上方に位置し、当該第1の斜材の他端部が他方の主柱材にあって下方に位置する場合も同様の効果を奏することができる。但し、この場合には、他方の主柱材における第1の斜材の他端部の下側に第1挟持部材を設け、一方の主柱材における第1の斜材の一端部の下側に第2挟持部材を設け、かつ当該一方の主柱材における第2挟持部材の下側に第3挟持部材を設けることになるが、その他の点では上述した手順と同様の手順で斜材の交換作業を行うことができる。   In the above description, one end portion of the first diagonal member on which the tensile load acts is in one main column member and is positioned below, and the other end portion of the first diagonal member is in the other main column member. In this case, the procedure and the effect when the first diagonal member and the second diagonal member are exchanged in the case of being positioned above are shown. However, the same applies to the case where one end of the first diagonal member is located on the upper side of one main pillar, and the other end of the first diagonal member is located on the lower side of the other main pillar. The effect of can be produced. However, in this case, a first clamping member is provided below the other end portion of the first diagonal member in the other main column member, and the lower side of one end portion of the first diagonal member in the one main column member The second sandwiching member is provided on the one main pillar member, and the third sandwiching member is provided on the lower side of the second sandwiching member in the one main column member. Exchange work can be performed.

以上より、想定を超える大きさの外力が鉄塔に作用した場合でも、摩擦力を利用して各主柱材に連結する端部である第1挟持部材や第2挟持部材が当該各主柱材に沿って移動するのを確実に防止することができ、斜材の交換作業を極めて安全に行うことができる。   As described above, even when an external force larger than expected is applied to the steel tower, the first clamping member and the second clamping member, which are ends connected to the main column members using frictional forces, are the main column members.

In this state, they are fixed by bolts B1 and nuts N1, and are connected to the support members 71 and 71 projecting outward from the first compression member 21 and the second compression member 22, and to the support members 71 and 71. And a load propagation member 72.

支持部材71は、図5に示すように、四角形の平板状の鉄板によって形成されたものであり、一方の辺に沿うように、2本のボルトB1がそれぞれ挿通する貫通孔が形成されていると共に、他方の辺に沿うように、荷重伝播部材72と連結するためのネジとしてのボルトB3の挿通する3つの貫通孔が形成されている。ボルトB3の挿通する3つの貫通孔は等間隔に形成されている。   As shown in FIG. 5, the support member 71 is formed by a rectangular flat iron plate, and through holes through which the two bolts B <b> 1 are inserted are formed along one side. At the same time, three through-holes through which bolts B3 as screws for connecting to the load propagation member 72 are inserted are formed along the other side. The three through holes through which the bolts B3 are inserted are formed at equal intervals.

荷重伝播部材72は、2本の山型鋼73、73によって構成されている。各山型鋼73には、その一方の鋼板部73aの長手方向に一定の間隔をおいて連結孔73bが複数形成されている。各連結孔73bは、支持部材71におけるボルトB3を挿通する貫通孔と同一のピッチ(間隔)で形成されている。このように構成された荷重伝播部材72は、各山型鋼73の一方の鋼板部73aで支持部材71を挟み付けた状態で、各連結孔73b等を通るボルトB3及びナットN3によって、当該支持部材71と強固に連結された状態になるようになっている。   The load propagation member 72 is composed of two angle steels 73 and 73. Each angle steel 73 is formed with a plurality of connecting holes 73b at regular intervals in the longitudinal direction of one of the steel plate portions 73a. The connecting holes 73b are formed at the same pitch (interval) as the through holes through which the bolts B3 in the support member 71 are inserted. The load propagation member 72 configured in this manner is supported by the bolts B3 and nuts N3 passing through the connection holes 73b and the like in a state where the support member 71 is sandwiched by one steel plate portion 73a of each angle steel 73. 71 is firmly connected to 71.

即ち、間隔維持部材7は、他方の主柱材P2にその軸方向に間隔をおいて取り付けられた第2挟持部材3と第3挟持部材6とを、支持部材71及び荷重伝播部材72によって強固に連結するようになっている。また、第2挟持部材3と第3挟持部材6との間隔は、当該第2挟持部材3及び第3挟持部材6に固定された各支持部材71、71の間の方向に一定の間隔で形成されたものとなる連結孔73bのピッチで調整することが可能になっている。   That is, the gap maintaining member 7 has a support member 71 and a load propagating member 72 that firmly attach the second holding member 3 and the third holding member 6 attached to the other main pillar member P2 at intervals in the axial direction. To be connected to. The interval between the second clamping member 3 and the third clamping member 6 is formed at a constant interval in the direction between the support members 71 and 71 fixed to the second clamping member 3 and the third clamping member 6. It is possible to adjust the pitch of the connecting holes 73b.

また、荷重伝播部材72には、他方の主柱材P2に沿って作業員の昇降を可能にするステップ駒74が連結孔73bを利用してネジとしてのボルトB3及びナットN3によって取付可能になっている。   In addition, a step piece 74 that allows the worker to move up and down along the other main pillar material P2 can be attached to the load propagation member 72 by means of a bolt B3 and a nut N3 as screws using the connection hole 73b. ing.

上記のように構成された鉄塔の斜材交換装置1においては、引張荷重を受ける第1の斜材S1であって、斜め下方に位置する第1の斜材S1の下端部の下側における一方の主柱材P1に第1挟持部材2を取り付け、斜め上方に位置する第1の斜材S1の上端部の下側における他方の主柱材P2に第2挟持部材3を取り付け、かつ当該第2挟持部材3の下側における他方の主柱材P2に第3挟持部材6を取り付ける。   In the steel tower diagonal material exchanging apparatus 1 configured as described above, the first diagonal material S1 that receives a tensile load, which is one below the lower end portion of the first diagonal material S1 located obliquely below. The first clamping member 2 is attached to the main pillar material P1, the second clamping member 3 is attached to the other main pillar material P2 on the lower side of the upper end portion of the first diagonal material S1 located obliquely above, and the first 2 The third clamping member 6 is attached to the other main pillar material P2 on the lower side of the clamping member 3.

この際、第1挟持部材2は、ガセットプレートG1の下縁に近接あるいは接するようにして、一方の主柱材P1に圧迫固定する。 At this time, the first clamping member 2 is pressed and fixed to one main pillar material P1 so as to be close to or in contact with the lower edge of the gusset plate G1.

一方、第2挟持部材3は、ガセットプレートG2の下縁近傍となるようにして、他方の主柱材P2に仮に圧迫固定する。 On the other hand, the second clamping member 3 is temporarily pressed and fixed to the other main pillar member P2 so as to be near the lower edge of the gusset plate G2.

また、第3挟持部材6は、ガセットプレートG4の上縁に近接あるいは接するようにして、他方の主柱材P2に圧迫固定する。   The third clamping member 6 is pressed and fixed to the other main pillar member P2 so as to be close to or in contact with the upper edge of the gusset plate G4.

そして、第2挟持部材3と第3挟持部材6とを間隔維持部材7で連結する。この際、第2挟持部材3がガセットプレートG2にできる限り接近した状態となるように、支持部材71と荷重伝播部材72との連結位置を調整してから、当該第2挟持部材3を他方の主柱材P2に正規に圧迫固定する。   Then, the second holding member 3 and the third holding member 6 are connected by the interval maintaining member 7. At this time, after adjusting the connecting position of the support member 71 and the load propagation member 72 so that the second holding member 3 is as close as possible to the gusset plate G2, the second holding member 3 is moved to the other side. The main pillar material P2 is normally pressed and fixed.

更に、ギヤターンバックル5を含む連結部材群4を第1挟持部材2及び第2挟持部材3に連結する。この際、長さ調整用小径管44と長さ調整用大径管45とにより連結部材群4の全長を大まかに調整した上で、当該全長をギヤターンバックル5で微調整することにより、この連結部材群4を第1挟持部材2及び第2挟持部材3に簡単に連結することができる。これにより、連結部材群4が第1の斜材S1に沿って延在した状態になる。   Further, the connecting member group 4 including the gear turnbuckle 5 is connected to the first holding member 2 and the second holding member 3. At this time, the overall length of the connecting member group 4 is roughly adjusted by the length adjusting small diameter tube 44 and the length adjusting large diameter tube 45, and then the total length is finely adjusted by the gear turnbuckle 5. The connecting member group 4 can be easily connected to the first holding member 2 and the second holding member 3. As a result, the connecting member group 4 extends along the first diagonal material S1.

以上のようにして、斜材交換装置1を鉄塔Tの所定の位置に設置した状態において、ギヤターンバックル5の長さを漸次縮減することにより、連結部材群4に引張荷重が徐々に発生することになる。これにより、第1の斜材S1に作用していた引張荷重が徐々に減少するので、当該第1の斜材S1の引張荷重が零になった時点でギヤターンバックル5による長さの減縮を停止する。この第1の斜材S1の引張荷重が零になる時点は、当該第1の斜材S1をガセットプレートG1、G2や中間プレートMに固定するボルトBがそのボルト挿通孔に対して移動自在となることから、簡単にかつ確実に確認することができる。そこで、第1の斜材S1を新たなものに交換する。   As described above, in the state in which the diagonal member replacement device 1 is installed at a predetermined position of the tower T, a tensile load is gradually generated in the connecting member group 4 by gradually reducing the length of the gear turn buckle 5. It will be. As a result, the tensile load acting on the first diagonal member S1 gradually decreases, and therefore the length reduction by the gear turnbuckle 5 is performed when the tensile load of the first diagonal member S1 becomes zero. Stop. When the tensile load of the first diagonal member S1 becomes zero, the bolt B for fixing the first diagonal member S1 to the gusset plates G1, G2 and the intermediate plate M is movable with respect to the bolt insertion hole. Therefore, it can be confirmed easily and reliably. Therefore, the first diagonal material S1 is replaced with a new one.

そして、更に、ギヤターンバックル5の長さを減縮調整し、第2の斜材S2の圧縮荷重を零にしてから、当該第2の斜材S2を新たなものに交換する。   Further, the length of the gear turnbuckle 5 is adjusted to be reduced and the compression load of the second diagonal material S2 is made zero, and then the second diagonal material S2 is replaced with a new one.

第1の斜材S1及び第2の斜材S2を交換した後は、ギヤターンバックル5を伸長する方向に調整をして、当該ギヤターンバックル5に作用する引張荷重を完全に除去した後、ギヤターンバックル5を含む連結部材群4を第1挟持部材2及び第2挟持部材3から取り外すことになる。また、第1挟持部材2、第2挟持部材3、第3挟持部材6及び間隔維持部材7については、そのまま各主柱材P1、P1から取り外すか、他の第1の斜材S1等の交換のため各主柱材P1、P2の所定の位置に移動する。   After exchanging the first diagonal material S1 and the second diagonal material S2, after adjusting the gear turn buckle 5 to extend and removing the tensile load acting on the gear turn buckle 5 completely, The connecting member group 4 including the gear turnbuckle 5 is removed from the first clamping member 2 and the second clamping member 3. Moreover, about the 1st clamping member 2, the 2nd clamping member 3, the 3rd clamping member 6, and the space | interval maintenance member 7, it removes from each main pillar material P1 and P1 as it is, or replacement | exchange of other 1st diagonal materials S1 etc. Therefore, it moves to a predetermined position of each main pillar material P1, P2.

以上のように作業することにより、引張荷重の作用する第1の斜材S1及び圧縮荷重の作用する第2の斜材S2を、簡単に交換することができる。   By working as described above, the first diagonal material S1 on which the tensile load acts and the second diagonal material S2 on which the compression load acts can be easily replaced.

また、第1挟持部材2及び第2挟持部材3は各主柱材P1、P2の外面を圧迫することによる摩擦力を利用して当該各主柱材P1、P2に固定しているので、突風等による想定外の大きさの外力が鉄塔Tに作用した場合には、各主柱材P1、P2に連結する端部である第1挟持部材2及び第2挟持部材3が当該各主柱材P1、P2に沿って移動するおそれがある。即ち、第1の斜材S1や第2の斜材S2は主柱材P1、P2に対してほぼ45度の方向に延在しており、連結部材群4もその角度とほぼ同じ方向に延在することになることから、想定外の大きさの外力が鉄塔Tに作用すると、連結部材群4に発生する引張荷重のうち各主柱材P1、P2の軸方向の分力が想定を超える大きさになり、第1挟持部材2又は第2挟持部材3が各主柱材P1、P2に沿って滑るおそれがある。   Moreover, since the 1st clamping member 2 and the 2nd clamping member 3 are fixing to each said main pillar material P1, P2 using the frictional force by pressing the outer surface of each main pillar material P1, P2, it has a gust of wind. When an external force of an unexpected magnitude due to the above acts on the steel tower T, the first clamping member 2 and the second clamping member 3 that are ends connected to the main pillar materials P1 and P2 are the main pillar materials. There is a risk of moving along P1 and P2. That is, the first diagonal material S1 and the second diagonal material S2 extend in a direction of approximately 45 degrees with respect to the main columnar materials P1 and P2, and the connecting member group 4 also extends in the same direction as the angle. Therefore, when an external force of an unexpected magnitude acts on the steel tower T, the axial component forces of the main column members P1 and P2 out of the tensile load generated in the connecting member group 4 exceed the assumption. There is a possibility that the first holding member 2 or the second holding member 3 may slide along the main pillar materials P1 and P2 due to the size.

この場合、連結部材群4から第1挟持部材2に作用する分力は、当該第1挟持部材2を一方の主柱材P1の軸方向上方に作用する力となる。また、連結部材群4から第2挟持部材3に作用する分力は、当該第2挟持部材3を他方の主柱材P2の軸方向下方に作用する力となる。   In this case, the component force which acts on the 1st clamping member 2 from the connection member group 4 turns into the force which acts on the said 1st clamping member 2 to the axial direction upper direction of one main pillar material P1. Moreover, the component force which acts on the 2nd clamping member 3 from the connection member group 4 turns into the force which acts on the said 2nd clamping member 3 to the axial direction downward direction of the other main pillar material P2.

しかし、第1挟持部材2については、ガセットプレートG1の下縁に近接あるいは接するように設けることができるので、一方の主柱材P1との間の摩擦力を超える分力が当該主柱材P1の軸方向の上方に作用したとしても、上方に滑り移動するのを確実に防止することができる。   However, since the first clamping member 2 can be provided so as to be close to or in contact with the lower edge of the gusset plate G1, the component force exceeding the frictional force between the main pillar material P1 is the main pillar material P1. Even if it acts upward in the axial direction, it is possible to reliably prevent sliding upward.

一方、第2挟持部材3は、他方の主柱材P2との間の摩擦力を超える分力が当該主柱材P2の軸方向の下方に作用したとしても、その摩擦力を超える力の成分が間隔維持部材7を介して第3挟持部材6に伝えられることになるので、その力の成分が第3挟持部材6における他方の主柱材P2との間の摩擦力を超えなければ、当該主柱材P2の軸方向の下方に移動することがない。また、上記力の成分が第3挟持部材6と他方の主柱材P2との間の摩擦力を超える大きさになったとしても、第3挟持部材6をガセットプレートG4の上縁に近接あるいは接するように設けることができるので、当該第3挟持部材6が下方に滑り移動するのを確実に防止することができ、よって第2挟持部材3も下方に移動するのを確実に防止することができる。   On the other hand, even if the component force exceeding the frictional force between the second clamping member 3 and the other main columnar material P2 acts below the main columnar material P2 in the axial direction, the component of the force exceeding the frictional force Is transmitted to the third clamping member 6 via the gap maintaining member 7, so that the component of the force does not exceed the frictional force between the other main pillar material P2 in the third clamping member 6 and It does not move downward in the axial direction of the main pillar material P2. Even if the component of the force exceeds the frictional force between the third clamping member 6 and the other main pillar member P2, the third clamping member 6 is brought close to the upper edge of the gusset plate G4 or Since it can be provided so as to contact, it is possible to reliably prevent the third clamping member 6 from sliding and moving downward, and thus to reliably prevent the second clamping member 3 from moving downward. it can.

なお、上記説明では、引張荷重が作用する第1の斜材S1の一端部が一方の主柱材P1にあって下方に位置し、当該第1の斜材S1の他端部が他方の主柱材P2にあって上方に位置する場合における当該第1の斜材S1及びこれに交差する第2の斜材S2を交換する際の手順及び効果を示した。しかし、第1の斜材S1の一端部が一方の主柱材P1にあって上方に位置し、第1の斜材S1の他端部が他方の主柱材P2にあって下方に位置する場合も同様の効果を奏することができる。但し、この場合には、他方の主柱材P2における第1の斜材S1の他端部の下側に第1挟持部材2を設け、一方の主柱材P1における第1の斜材S1の一端部の下側に第2挟持部材3を設け、かつ当該一方の主柱材P1における第2挟持部材3の下側に第3挟持部材6を設けることになるが、その他の点では上述した手順と同様の手順で斜材S1、S2の交換作業を行うことができる。   In the above description, one end portion of the first diagonal member S1 to which a tensile load acts is located on one main column member P1 and located below, and the other end portion of the first diagonal member S1 is the other main portion. The procedure and the effect at the time of exchanging the first diagonal material S1 and the second diagonal material S2 intersecting with the first diagonal material S1 in the column material P2 positioned above are shown. However, one end portion of the first diagonal member S1 is positioned on the upper side of the one main pillar material P1, and the other end portion of the first diagonal member S1 is positioned on the lower side of the other main column member P2. In this case, the same effect can be obtained. However, in this case, the first clamping member 2 is provided below the other end portion of the first diagonal member S1 in the other main column member P2, and the first diagonal member S1 in the one main column member P1 is provided. The second clamping member 3 is provided on the lower side of the one end portion, and the third clamping member 6 is provided on the lower side of the second clamping member 3 in the one main columnar material P1. The diagonal materials S1 and S2 can be exchanged in the same procedure as the procedure.

以上より、想定を超える大きさの外力が鉄塔Tに作用した場合でも、摩擦力を利用して主柱材P1、P2に連結する端部である第1挟持部材2や第2挟持部材3が当該主柱材P1、P2に沿って移動するのを確実に防止することができ、斜材の交換作業を極めて安全に行うことができる。   From the above, even when an external force exceeding the expected value acts on the steel tower T, the first clamping member 2 and the second clamping member 3 that are ends connected to the main pillar materials P1 and P2 using the friction force are used. It is possible to reliably prevent movement along the main pillar materials P1 and P2, and it is possible to perform the replacement work of the diagonal materials extremely safely.

また、一対の連結部材群4が鉄塔構面Aの両側に所定の間隔をおいて均等に振り分けられるようにして設けられることになるので、連結部材群4が第1の斜材S1や第2の斜材S2に干渉するのを避けることができると共に、第1の斜材S1に代わって、当該第1の斜材S1と同様にバランスの良い安定した引張荷重を各主柱材P1、P2に作用させることができる。   Further, since the pair of connecting member groups 4 are provided on both sides of the steel tower construction surface A so as to be evenly distributed at a predetermined interval, the connecting member group 4 is provided with the first diagonal member S1 and the second oblique member S2. Can be avoided, and instead of the first diagonal material S1, a stable tensile load with a good balance can be applied to each of the main column members P1, P2 in the same manner as the first diagonal material S1. Can act on.

更に、第1挟持部材2、ギヤターンバックル5を含む連結部材群4の各連結部材及び第2挟持部材3は、互いに隣り合う部材が軸部材としてのボルトB2によって回動自在に連結されるようになっているので、ギヤターンバックル5によって張力が発生した際には各ボルトB2が一直線上に配置された状態になり、連結部材群4が一直線上に並んだ極めて安定した状態になる。従って、安全性の向上を図ることができる。しかも、引張荷重を解除した際には、その荷重が完全に除去されたことを各ボルトB2の位置で容易に確認することができる利点がある。   Further, the connecting members of the connecting member group 4 including the first holding member 2 and the gear turnbuckle 5 and the second holding member 3 are connected so that the members adjacent to each other are rotatable by a bolt B2 as a shaft member. Therefore, when tension is generated by the gear turnbuckle 5, the bolts B2 are arranged in a straight line, and the connecting member group 4 is in a very stable state in a straight line. Therefore, safety can be improved. Moreover, when the tensile load is released, there is an advantage that it can be easily confirmed at the position of each bolt B2 that the load has been completely removed.

第1挟持部材2、第2挟持部材3及び第3挟持部材6がそれぞれ第1圧迫部材21と第2圧迫部材22とを備えたものとなっているので、これらの第1圧迫部材21及び第2圧迫部材22をボルトB1及びナットN1で連結して主柱材P1、P2に押し付けることにより、当該第1挟持部材2、第2挟持部材3及び第3挟持部材6を一方及び他方の主柱材P1、P2における任意の位置に容易に固定することができる。   Since the 1st clamping member 2, the 2nd clamping member 3, and the 3rd clamping member 6 are each provided with the 1st compression member 21 and the 2nd compression member 22, these 1st compression members 21 and 2nd The two pressing members 22 are connected by bolts B1 and nuts N1 and pressed against the main pillar materials P1 and P2, thereby connecting the first clamping member 2, the second clamping member 3 and the third clamping member 6 to one and the other main pillars. It can be easily fixed at an arbitrary position in the materials P1 and P2.

また、間隔維持部材7は、ボルトB1及びナットN1を用いて第2挟持部材3及び第3挟持部材6のそれぞれに固定される支持部材71、71と、これらの支持部材71、71にボルトB3及びナットN3を用いて連結される荷重伝播部材72とを備えているので、第2挟持部材3と第3挟持部材6との間の力の伝達を確実に行うことができると共に、第2挟持部材3及び第3挟持部材6に対する荷重伝播部材72の着脱を容易に行うことができる。   The spacing maintaining member 7 includes support members 71 and 71 fixed to the second sandwiching member 3 and the third sandwiching member 6 using bolts B1 and nuts N1, and bolts B3 to the support members 71 and 71, respectively. And the load propagation member 72 connected using the nut N3, the force transmission between the second clamping member 3 and the third clamping member 6 can be reliably performed, and the second clamping is performed. The load propagation member 72 can be easily attached to and detached from the member 3 and the third clamping member 6.

しかも、荷重伝播部材72は支持部材71とボルトB3及びナットN3で連結するための連結孔73bを所定の間隔をおいて複数有しているので、その連結孔73bの間隔で第2挟持部材3をガセットプレートG2の下縁近傍に位置させることができる。   In addition, since the load propagation member 72 has a plurality of connection holes 73b that are connected to the support member 71 by bolts B3 and nuts N3 at a predetermined interval, the second clamping member 3 is spaced at intervals of the connection holes 73b. Can be positioned near the lower edge of the gusset plate G2.

更に、ステップ駒74が荷重伝播部材72の連結孔73bを利用してボルトB3及びナットN3で当該荷重伝播部材72に取付可能に構成されているので、間隔維持部材7を設置するために、他方の主柱材P2に設けたステップ駒を一時的に取り外す必要が生じた場合でも、作業員の昇降に支障をきたすことがないという利点がある。   Further, since the step piece 74 is configured to be attachable to the load propagation member 72 with the bolt B3 and the nut N3 using the connection hole 73b of the load propagation member 72, Even when it is necessary to temporarily remove the step piece provided on the main pillar material P2, there is an advantage that it does not hinder the lifting and lowering of the worker.
