CONSTRUCTION METHOD OF DOUBLE SHELL TANK AND SIDE PLATE MOUNTING DEVICE USED FOR THE METHOD

摘要

PROBLEM TO BE SOLVED: To easily and quickly perform construction by attaching a side plate mounting device to the top part of the uppermost side plate of an already constructed inner wall, and stacking the side plate on the top part of an outer wall by means of the side plate mounting device in a matching state, and connecting them by welding. ;SOLUTION: A side plate mounting device A is mounted on the uppermost side plate 12 constituting an inner wall 11, one end of a connection wire 19 is engaged to the engaging part 18 of both the side plates 12, and the other end is engaged to the hook of a hanging hoist 16 to be light. Next, a traverse motor is driven to move the side plate toward a radius direction, both the side plates 12 are lowered, mounted to be abutted on the upper part end face of the uppermost side plate 12 constituting an already built outer wall 10, and connection is performed by welding. Next, the device A is removed by a crane or the like, and attached to the top part of the uppermost side plate 12 of the outer wall 10 to construct the inner wall 11. Thereby a double shell tank can be easily and quickly constructed by mounting the device A on the inner wall 11 or the outer wall 12 and moving it.;COPYRIGHT: (C)1998,JPO
