However, after use, since the clamps and lugs are already welded together, they can only be removed by cutting both the lugs and clamps simultaneously using a gas cutter. This method results in the clamps and lugs being unable to be reused after cutting, which is not conducive to the reuse of components. The need to prepare new clamps and lugs each time increases material costs and also increases the construction period due to the cutting and reinstallation process.
