Embodiment 1

[0054] Example 1: Fixture for vertical weld adjustment

[0055] In the construction method of the present invention, most of the entire wall board can be adjusted to the required radian by the elasticity of the steel plate, but the rigidity at the junction of the two edges of the wall board is high, so it is difficult to automatically adjust the required radian . For this reason, the inventor of the present invention has invented a vertical welding seam adjustment jig with simple structure, convenient adjustment, easy mastery and high adjustment accuracy after years of repeated research and testing, and realized the adjustment of vertical cylindrical storage tanks. The non-coiling construction method is the special key equipment for realizing the technology of the present invention.

[0056] 1. The structure of vertical welding seam adjustment jig

[0057] refer to figure 1 , 2 , this vertical seam adjustment jig is made up of a vertical seam positioning plate 1 and a vert...

Abstract

The invention relates to a plate-rolling-free construction method for a vertical cylindrical storage tank and a clamp thereof. The method comprises the following steps: during construction, not using a plate roller to roll a wall plate of the storage tank, correspondingly welding at least one vertical welding line positioning plate at two edges inside the wall plate, welding at least one wall plate positioning frame at the upper edge and the lower edge, regulating radians of most wall plates by adopting the elasticity of the most wall plates for direct installation, and regulating the width of the vertical welding lines at the joint of each wall plate, the radians of the wall plates, the vertical positioning of each wall plate, and the like by using a special vertical welding line adjusting clamp and other normal clamps, to achieve assembly installation of the wall plates at the cylindrical part of the tank. The method has the advantages of simple and easily-mastered installation construction process, simple structure and low cost of the required clamps, fewer constructors and auxiliary facilities, low intensity of labor, short construction period, low cost, good installation quality, wide application range, and the like. Compared with the plate rolling construction method, the method can save labor by more than 5 percent, can reduce the construction period and the construction cost by more than 10 percent, and has great popularization value.

Description

technical field [0001] The invention relates to the improvement of the construction method of a vertical cylindrical storage tank, in particular to a non-coiling construction method of a vertical cylindrical storage tank and a fixture thereof. Background technique [0002] The installation and construction of vertical cylindrical storage tanks is a routine work in the installation work of chemical buildings. It has always been to use the plate rolling machine to pre-roll the steel plate (wall plate) to the required radian, and then use the front or reverse installation method. It can be installed according to the method, and then welded by automatic or manual welding to form a storage tank. This construction method has the disadvantages of complex installation and construction process, many construction personnel and auxiliary equipment, high labor intensity, long construction period and high cost. Contents of the invention [0003] The purpose of the present invention is...
