Quality cabinet system, and construction method thereof, and construction method for tuned mass damper

The invention provides a quality cabinet system and a construction method thereof. The method comprises: arranging a jig frame on a supporting floor; arranging a spacing shaft on the jig frame, arranging at least a second supporting beam on the jig frame on two sides of the spacing shaft; laying a cabinet bottom board on the jig frame, making the spacing shaft pass through the cabinet bottom board; fixing a plurality of cabinet vertical plates on the cabinet bottom board, to form a plurality of cavity whose side walls are the cabinet vertical plates, the bottom ends are the cabinet bottom board, and the top ends are an opening end; arranging a plurality of balancing weights in the cavities, and fixing a cabinet top plate on the top end of a cabinet vertical plate module and/or the balancing weights. The invention also provides a construction method for a tuned mass damper. The method comprises using the construction method for the quality cabinet system to assemble a quality cabinet system, assembling a current vortex system; and abutting the quality cabinet system with the current vortex system. The method ensures construction quality and precision of the quality cabinet system, and ensures reasonable and optimal construction period.
