The first support, the second support, the stull, the bracing is welded on the bottom plate with bottom plate central symmetry.

By 2 above-mentioned devices use for a set of during the use, 2 arc wallboards can be put to a set of device, according to the size of wallboard, adjust the distance between 2 devices when putting, can be suitable for putting of all present arc storage tank wallboards of size, the wallboard is vertical to be put back non-deformable, and the welder's anchor clamps on the wallboard of being convenient for can direct hoist and mount when the wallboard is installed.

The utility model has the beneficial effects that:

the utility model provides a device for vertically placing arc-shaped wall plates of a storage tank, which can ensure that the wall plates are not deformed when placed, is suitable for various wall plate sizes and is convenient to move. The device solves the problems of high material consumption, difficult carrying and complex lifting of a large number of horizontal clamping tools in the prior art, has low cost, simple structure, strong practicability and flexible arrangement, and improves the installation efficiency of the storage tank wall plate. In addition, the device can be directly hoisted when the wall plate is installed, and compared with the traditional mould, the device has the advantages of simple processing and manufacturing, less material consumption, light weight and convenient transportation of the rack; compared with the traditional horizontal placement, one step of placing the wall plate from horizontal to vertical is omitted during hoisting, so that the method is more trouble-saving, faster and safer; compared with the traditional horizontal placement, the vertical placement has the advantages that the occupied space is small, and the vertical placement is more advantageous when the construction site is narrow.
