Spherical tank pre-weldment setting-out device and construction method thereof

Abstract

The invention relates to the technical field of spherical tank installation engineering, in particular to a spherical tank pre-weldment setting-out device and construction method thereof. The setting-out device comprises a support base, a height adjusting mechanism, a balance adjusting mechanism and an orientation disc. The method comprises the following steps that S1, a setting-out device is fixed, wherein the setting-out device is fixed to a spherical tank manhole through a base positioning sliding block; S2, setting-out device adjustment, wherein the setting-out device is heightened and leveled through the height adjusting mechanism; S3, data is measured, wherein the required data H1 and H4 are measured; and S4, data is calculated, wherein the data is calculated according to the setting-out radius and a setting-out formula, and the data displayed on a range finder is enabled to be consistent with a calculation structure by adjusting the angle of the laser range finder on the setting-out device. According to the spherical tank pre-weldment setting-out device and construction method thereof, the operation is easy and convenient, construction efficiency is improved, construction safety is improved, setting-out precision is guaranteed, and construction cost is reduced.

[0002] As we all know, the spherical tank is a large-capacity, pressure-bearing and efficient storage container, which is widely used in the chemical industry due to its superior performance. There are great dangers in the construction process, especially during the lofting and positioning process of the upper and lower plate pre-welded backing plates on the outer surface of the spherical shell, the construction personnel need to frequently reciprocate on the surface of the spherical shell, and most of the arc The Xingri clamps have also been dismantled, and there are fewer places for the construction workers to hang their safety belts. As a result, there is a huge potential safety hazard. Therefore, a new construction method has been developed to solve the problem of spherical tank lofting. safety concerns are significant

[0003] At present, in the spherical tank installation project, the stakeout of the prefabricated weldment of the spherical tank mainly adopts the traditional manual stakeout. The main operation step is to place the square at the manhole to find the center of the manhole, and the construction personnel pinches the stakeout thread or pulls the tape measure Stakeout operation, the stakeout accuracy deviation is too large, the stakeout range is small, and the operation is inconvenient

Especially when setting out the bottom plate of the spherical tank, the difficulty of setting out is more difficult, which seriously affects the progress of the project and increases the construction cost
