CONNECTION RELEASING TOOL
PROBLEM TO BE SOLVED: To provide a connection releasing tool capable of efficiently releasing connection between a ceiling joist receiver and a ceiling joist in a short time without requiring time and trouble.SOLUTION: A connection releasing tool 10A is formed by: a long operation rod 11; a guide bar 13 extending from an upper end part 12 of the operation rod 11 in the width direction; and a lever head 14 extending from the upper end part 12 of the operation rod 11 in the width direction, being separated at a predetermined dimension upward from the guide bar 13. The lever head 14 is formed by: a first plate 24 extending in the vertical direction; a second plate 25 extending in the frontward/backward direction; and a pair of support bars 26a, 26b extending frontward from the second plate 25. In the connection releasing tool 10A, the support bars 26a, 26b lift a ceiling joist receiver upward and separate the ceiling joist receiver and a ceiling joist in the vertical direction, and engagement between an upper flange of the ceiling joist receiver and a first hook of a connection clip is released.SELECTED DRAWING: Figure 1
【課題】手間と時間とを要せずに野縁受けと野縁との連結を短時間で効率よく解除することができる連結解除具を提供する。【解決手段】連結解除具１０Ａは、長尺の操作ロッド１１と、操作ロッド１１の上端部１２から幅方向へ延出する案内棒１３と、案内棒１３から上方へ所定寸法離間して操作ロッド１１の上端部１２から幅方向へ延出する梃子ヘッド１４とから形成されている。梃子ヘッド１４は、上下方向へ延びる第１プレート２４と、前後方向へ延びる第２プレート２５と、第２プレート２５から前方へ延出する一対の支持棒２６ａ，２６ｂとから形成されている。連結解除具１０Ａでは、支持棒２６ａ，２６ｂが野縁受けを上方へ持ち上げて野縁受けと野縁とを上下方向へ離間させ、野縁受けの上フランジと連結クリップの第１フックとの係合が解除される。【選択図】図１
