The invention discloses a
vibration isolation structure of a shaftway lower-hanging type converting bracket and a construction method of the
vibration isolation structure. The
vibration isolation structure is characterized in that a converting beam of an out-extending bracket is arranged on the periphery of a shaftway or a core cylinder, the top elevation of the converting beam is flush with the top elevation of a
basement top plate, a
basement hanging structure of the shaftway or the core cylinder is arranged below the converting beam, the converging beam is arranged on a vibration isolation supporting base through the bracket, vibration isolation grooves are formed between the
basement hanging structure, a basement bottom plate and a basement stand column, and specific construction comprises underground layer construction and hanging and vibration
isolation layer structure construction. Compared with the prior art, the basement hanging structure of the shaftway or the core cylinder and a structure below a vibration
isolation layer are complete separated, vibration
isolation effect is good, the problem that a vibration isolation seam is too wide, shaftway vertical aligning cannot be achieved, and the shaftway or a core cylinder side supporting base is pulled is effectively solved, structure stability is good, the vibration isolation support is flexibly arranged in different structure systems, and construction mounting and later-period maintaining are convenient.
