TENSIONING FORCE VARIATION DISPLAY DEVICE OF GROUND ANCHOR
PROBLEM TO BE SOLVED: To provide a tensioning force variation display device which can immediately grasp a variation state of a tensioning force of a tensioning material by merely visually confirming a head anchored body of the tensioning material on a ground surface while being simple in a constitution which does not need a power supply when a variation occurs at the tensioning force of the tensioning material in a use state of a ground anchor which is embedded into the ground in a state that the tensioning force is imparted to the tensioning material.SOLUTION: A tensioning force variation display device 1 is constituted of: an anchor body 12 which is connected to a tip of a tensioning material 11 at a ground side, and anchored into the ground; a cable 2 which is connected to a head of the tensioning material 11 at a ground surface side, bridged between a head anchoring body 13 which is anchored on a ground surface in a state of being exposed to the ground surface, connected to the anchor body 12 at the end of the anchor body 12 side, and connected to a spring 4 connected to the head anchoring body 13 at the end of the head anchoring body 13 side; and a rotating body 3 which is rotatably supported to the head anchoring body 13, and rotates in conjunction with the elongation/contraction of the cable 2.SELECTED DRAWING: Figure 1
【課題】緊張材に緊張力が付与された状態で地中に埋設された地盤アンカーの使用状態で緊張材の緊張力に変動が生じたときに、電源を必要としない簡素な構成でありながら、地表面において緊張材の頭部定着体を目視することのみにより緊張材の緊張力の変動状態を直ちに把握可能にする緊張力変動表示装置を提供する。【解決手段】緊張材１１の地盤側の先端部に接続され、地中に定着されるアンカー体１２と、緊張材１１の地表面側の頭部に接続され、地表面に露出した状態で地表面に定着される頭部定着体１３との間に架設され、アンカー体１２側の端部においてアンカー体１２に接続され、頭部定着体１３側の端部において頭部定着体１３に接続されたばね４に接続されるケーブル２と、頭部定着体１３に回転自在に支持され、ケーブル２の伸縮に連動して回転する回転体３から緊張力変動表示装置１を構成する。【選択図】図１
