Setting-out tool and setting-out method for steel pipe construction

Abstract

The invention provides a setting-out tool and setting-out method for steel pipe construction, and belongs to the technical field of steel pipe construction. The setting-out tool comprises a plastic adhesive tape and a plurality of welding electrodes fixedly adhering to the plastic adhesive tape in a certain sequence, wherein the end, without the plurality of welding electrodes bonded, of the plastic adhesive tape forms a shape of a wave. The tool and the method are based on existing materials, are convenient and efficient, have high accuracy, are excellent in performance especially in saddle-shaped connector setting-out, and are effective tool and method for setting-out before welding pipelines.

Description

technical field [0001] The invention belongs to the technical field of steel pipe construction, and in particular relates to a lofting tool and a lofting method for steel pipe construction. Background technique [0002] At present, the common connection methods in the construction of ordinary steel pipes are: counterpart connection and saddle connection. Among them, the saddle connection needs to carry out lofting flame cutting on the pipe head of one pipe and the pipe body of the other pipe, and then weld them by electric welding. This is used to change the direction of the pipeline and the direction of the fluid in the pipeline. In most existing construction processes, engineers use special stakeout tools or empirical formulas for stakeout and calculation. Although the stakeout requirements are met, this method still exists. The following issues need to be improved: 1. On-site tools and tools need to be fully prepared, any loss of parts will affect the entire lofting proce...

The following issues need to be improved: 1. On-site tools and tools need to be fully prepared, and the loss of any parts will affect the entire lofting process

2. Empirical formula calculation and line drawing are cumbersome, not intuitive enough, and there is a risk of calculation errors
