Double-layer PC plate type conversion layer of post-poured upper-portion structure and construction method

Abstract

The invention provides a double-layer PC plate type conversion layer of a post-poured upper-portion structure and a construction method. The double-layer PC plate type conversion layer comprises a first-layer RC conversion plate and a second-layer RC conversion plate, and the first-layer RC conversion plate and the second-layer RC conversion plate are supported through frame columns to form a hollow layer. The thickness of the first-layer RC conversion plate is smaller than that of the second-layer RC conversion plate, and hidden beams are arranged in the second-layer RC conversion plate. A post-poured shearing wall, an energy consumption shearing wall and a friction damp mechanism are mounted in the hollow layer. A certain quantity of steel bars are configured in the upper and lower plates of the conversion layer, an energy consumption device is arranged between layers, thus the mass of the conversion layer plates is decreased, and the conversion layer plates have the enough bearing capacity to meet the upper-portion post-poured building structure. Through arrangement of interlayer special components, the structural integrity is reinforced, the structural seismic performance is reinforced, and thus the upper-down adjacent layers of the conversion layer do not become the anti-seismic weak layers.

Description

technical field [0001] The invention belongs to the field of construction engineering and relates to a transfer layer structure in a building structure, in particular to a double-layer RC plate transfer layer of a post-cast superstructure and a construction method. Background technique [0002] Setting up transfer floors in buildings with complex shapes and diverse functional requirements is an effective method for structural engineers to realize the type conversion of upper and lower floors, change the column network and axis of the upper and lower floors, or simultaneously transform the structural form and structural axis layout. . Since the concept of the transfer floor structure was proposed in the 1950s and 1960s, the analysis methods and design techniques of the transfer floor structure have become more and more diversified and mature, which has made the transfer floor structure more and more popular in modern high-rise buildings. more and more widely used. Several t...
