Document Type and Number:
WIPO Patent Application WO/2019/056715
Kind Code:
A1
Abstract:
A mixed-connection post-tensioned prestressed assembly concrete frame architecture and a construction method therefor. Said frame architecture comprises a foundation (1), frame columns (2), frame beams (3) and floor plates (4); connection steel bars (5) are embedded in the designated positions, inside the foundation (1), corresponding to the frame columns (2); each connection steel bar (5) is in an L shape and comprises a vertical edge and a transverse edge connected to one side of the bottom end of the vertical edge; the lower portion of the vertical edge and the transverse edge of each connection steel bar (5) are embedded in the foundation (1), and the portion, embedded in the foundation (1), of the connection steel bar (5) comprises a connection steel bar bonding section (5.1) and a connection steel bar non-bonding section (5.2); the connection steel bar non-bonding section (5.2) is located on the position of the vertical edge where is on the lower side of the top surface of the foundation (1) and on the end close to the foundation (1), and the length of the connection steel bar non-bonding section (5.2) is 3-20 times the diameter of the connection steel bar (5); and the connection steel bar bonding section (5.1) is located on the position of the vertical edge where is on the lower side of the top surface of the foundation (1) and on the end close to the transverse edge, and is located on the transverse edge of the connection steel bar (5). The structural system and the construction method therefor solve the technical problems in an existing structural system such as, the transporting lifting being difficult, the structural robust performance being low, the wet working quantity being large, and the repairing cost of column feet after earthquakes being high.
