摘要： PURPOSE:To avoid the need for welded parts and tighten water sealing bolts without draining water from a tank by a method wherein stave locks are fastened to a side wall with the water sealing bolts and a stay with a threaded part at each end is connected to the stave lock with nuts for the reinforcement thereof. CONSTITUTION:The stave locks 4 with a bent piece 5 and a stay attaching plate 11 are provided in an opposing manner across the joint edges of the panels at an intersecting part of the four unit panels 2 forming the side wall 14 of a panel erection type tank. The stave lock 4 is fastened via its packing 9 to the unit panel 2 with water sealing bolts 7. The head part of the water sealing bolt 7 has a nearly square shape and, when the water sealing bolt 7 is rotated, the nearly square bolt head contacts with the bent piece 5 to prevent its idle rotation. A stay 3 has a threaded part at each end and is connected to the stay attaching plates 11 on both the sides with nuts 19 to reinforce the panel erection type tank from inside.
