TENSION CONTROL DEVICE AND GUARD FENCE
To provide a tension control device and a guard fence capable of controlling damping performance according to the magnitude of a tensile force acting on a stay rope and reducing the required cross-sectional performance of a support post.SOLUTION: A stay rope 40 arranged between an upper part of a support post 10 and an upper side of a protective net 20, and a tension control device 30 of the stay rope 40 are used. The tension control device 30 includes a peripheral wall 32 provided on the upper part of the support post 10, and a driven restraint mechanism 50 arranged inside the peripheral wall 32. Both ends of the stay rope 40 extending to the outside of the tension control device 30 are connected to the upper side of the protective net 20 located on both sides of each support post 10 so that the tensile force generated in the stay rope 40 is dampened by the tension control device 30 when receiving an impact and the tensile force is transmitted in a chain reaction from a receiving span to an adjacent span through the stay rope 40.SELECTED DRAWING: Figure 3
【課題】ステーロープにはたらく引張力の大きさに応じて減衰性能を制御できて、要求される支柱の断面性能を小さくできる、張力制御装置及び防護柵を提供すること。【解決手段】支柱１０の上部と防護ネット２０の上辺間に配索されたステーロープ４０と、ステーロープ４０の張力制御装置３０とを使用する。張力制御装置３０は支柱１０の上部に設けた周壁３２と、周壁３２の内側に配設した従動拘束機構５０とを具備する。受撃時にステーロープ４０に生じる引張力を張力制御装置３０で減衰しつつ、ステーロープ４０を通じて受撃スパンから隣接するスパンへ連鎖的に引張力を伝達するように、張力制御装置３０の外部に延出したステーロープ４０の両端を各支柱１０の両側に位置する防護ネット２０の上辺に連結する。【選択図】図３
