Vibration isolation structure of shaftway lower-hanging type converting bracket and construction method of vibration isolation structure

Abstract

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.

Description

[0001] technical field [0002] The invention relates to the field of construction engineering seismic isolation technology, in particular to a seismic isolation structure and a construction method for a hoistway hanging conversion bracket used in construction engineering. Background technique [0003] In the design and application of seismic isolation technology in construction engineering, the layout and design of the isolation layer is a key. The seismic isolation layer is generally arranged on the top of the foundation of the building or the top of the basement column, but the installation of the seismic isolation layer at these two locations will cause some problems respectively. Because general buildings, especially high-rise structures, have basements with different areas, if the seismic isolation layer is set on the top of the foundation, vertical isolation joints of a certain width must be provided around the building. Function, construction installation and later ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a seismic isolation structure and construction method of a hoistway hanging conversion corbel in view of the deficiencies in the prior art. The hoistway or the core tube is equipped with transfer beams around the shaft, and the basement part of the shaft or the core tube is Suspended at the lower part of the transfer beam and rested on the shock-isolation support through the corbel structure, the suspension part is completely separated from the structure below the shock-isolation layer to meet the design requirements of the shock-isolation design, effectively solving the problem of too wide a shock-isolation joint and the vertical inability of the hoistway. Aligning and reducing the tension of shaft or core tube side supports has the advantages of good structural stability, more flexible arrangement of seismic isolation supports in different structural systems, convenient construction, installation and later maintenance, and accelerated construction progress
