Seismic isolation structure and construction method of a hoistway-hung transfer beam

Abstract

The invention discloses a shock insulation structure for under-shaft hanging type transfer girders, and a construction method of the shock insulation structure. The shock insulation structure and the construction method are characterized in that the transfer girders with outward-extending sections are arranged around a shaft or a core cylinder, and the top scale height of the transfer girders is flush with the top scale height of a ceiling of a basement; a basement hanging structure for the shaft or the core cylinder is arranged on the transfer girders, and the transfer girders are placed on shock insulation supports through the outward-extending sections; shock insulation grooves are formed between the basement hanging structure and a basement bottom plate and between the basement hanging structure and basement stand columns; construction includes construction of an underground layer structure, construction of the hanging structure and construction of a shock insulation layer structure. Compared with the prior art, the shock insulation structure and the construction method have the advantages that the basement hanging structure for the shaft or the core cylinder is completely disengaged from the structure below a shock insulation layer so as to meet the requirement for shock insulation, the problems that shock insulation seams are extremely wide, alignment can not be achieved for the shaft in the vertical direction, and tension on the supports around the shaft or the core cylinder is reduced are effectively solved, structural stability is high, the shock insulation supports are more flexibly arranged in different structural systems, and construction, installation and post-maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of seismic isolation of construction engineering, in particular to a seismic isolation structure and a construction method of an under-hung transition beam in a shaft used in construction engineering. Background technique [0002] 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 maint...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a seismic isolation structure and construction method of a hoistway hanging transfer beam in view of the deficiencies of the prior art. A transfer beam is arranged around the shaft or the core tube, and the basement part of the shaft or the core tube is suspended It is located at the lower part of the transfer beam, and rests on the isolation support through the extended section, so that the suspension part is completely separated from the structure below the isolation layer to meet the requirements of isolation design, effectively solving the problem of too wide isolation joints and vertical wells. It is impossible to align and reduce the tension of the side support of the shaft or the core tube. It has the advantages of good structural stability, more flexible arrangement of seismic isolation bearings in different structural systems, convenient construction, installation and later maintenance, and accelerated construction progress.
