The invention relates to an overhanging anchoring type segmented post-tensioning assembly type self-resetting wall system which is formed by combining wall bodies which are sequentially spliced from a foundation (1) from bottom to top, the system comprises connecting layers (8) and standard layers (2), a plurality of standard layers (8) and a section of connecting layer (2) form a group, and the standard layers (2) and the connecting layers (8) are spliced through post-tensioning prestressed tendons in each group; the lower part of the connecting layer (8) is symmetrically provided with overhanging tensioning ends, namely protruding wedge-shaped bumps (9) on two sides of the wall body, and the upper surface of the connecting layer (8) is provided with anchoring ends (4); prestressed tendon hole channels (3) are reserved in the standard layer (2) and the connecting layer (8), and space is reserved for the anchoring ends (4) of the upper prestressed tendons and the upper prestressed tendon hole channels (3) through the curved lower prestressed tendon hole channels (3). Compared with the prior art, the method has the advantages that the prestress is segmented and controllable, the structural damage after an earthquake is low, the residual displacement is small, and full-assembly construction is achieved.
本发明涉及一种外伸锚固式分段后张装配式自复位墙体系，由从基础(1)自下而上依次拼接的墙体组合构成，所述的体系包括连接层(8)和标准层(2)，以若干标准层(8)和一段连接层(2)为一组，每一组内通过后张预应力筋将标准层(2)和连接层(8)拼接；所述连接层(8)的下部在墙体两侧对称设置有外伸式张拉端，即突出的楔形凸块(9)，上表面布置有锚固端(4)；所述标准层(2)和连接层(8)的内部皆预留预应力筋孔道(3)，通过曲线型下部预应力筋孔道(3)为上部预应力筋的锚固端(4)和上部预应力筋孔道(3)让出空间。与现有技术相比，本发明具有预应力分段可控、结构震后损伤低、残余位移小和全装配施工的优点。
