Integrated assembly joint and method for isolation tier rubber bearing and column-beam slab system

Abstract

The invention discloses an integrated assembly joint for an isolation tier rubber bearing and column-beam slab system. The integrated assembly joint comprises upper embedded plates, a rubber bearing and lower embedded plates; the rubber bearing is connected between the upper embedded plates and the lower embedded plates; an upper concrete-filled steel tubular column is arranged on the upper embedded plates in nested manner; a lower concrete-filled steel tubular column is arranged on the lower embedded plates in nested manner; the upper concrete-filled steel tubular column is connected with thebeam slab system. The integrated assembly joint is convenient to construct and simple to process and has reliable aseismic performance; a new route and measure is provided for the assembly design andconstruction method of an isolation structure; the integrated assembly joint has important engineering significance to the development of prefabricated isolation building structures; an effective measure is provided for solving the mounting technique and construction method of the prefabricated isolation structures.

Description

technical field [0001] The invention belongs to the technical field of assembled reinforced concrete structures, and relates to an integrated assembly node and method of a rubber bearing of a shock-isolation layer, a column, and a beam-slab system. Background technique [0002] As a good structural form for resisting earthquakes, the isolation structure has been widely used in the vast earthquake areas of our country. It is bound to become a trend to comprehensively improve the comprehensive ability of my country's building structures to resist earthquakes, minimize the loss of earthquake disasters, and vigorously promote the application of shock absorption and isolation technology in building structures. [0003] The design of the isolation floor is a very important link in the design process of the isolation structure. It has always been the focus of engineering designers and construction personnel. The design and selection of the beam-column system of the isolation floor ...

AI Technical Summary

Problems solved by technology

Problem 1 The beam-slab system of the seismic isolation layer is constructed separately, the overall performance is poor, and the construction efficiency is low

The second problem is that the installation and construction of the embedded connectors are more difficult, the position of the embedded components is difficult to determine, and the flatness is difficult to control

The third problem is that the fixing and installation process of the upper and lower connecting plates of the seismic isolation support is relatively complicated, and it is difficult to install the connecting parts in place

The fourth problem is that the design and construction of the upper and lower connecting columns (pillars) of the seismic isolation bearing are generally more reinforced, which seriously affects the construction quality and efficiency.
