Annular prestress tensioning enhancing or reinforcing device and method
The invention relates to a circumferential prestress tension strengthening or reinforcing device, which is characterized in that a strengthening or reinforcing object is a column, a cylinder or a tubular body, and comprises a pier, a cover beam, a pier column, a cable bent tower, a large silo and a pipeline. Pre-compressive stress is applied to the pre-stressed carbon fiber plate body by adopting a pre-stressed carbon fiber plate body outer surrounding component, so that tensile stress generated by a load can be partially or completely eliminated. The device comprises a carbon fiber plate or a carbon fiber plate group, and is characterized in that anchorage devices are mounted at two ends of the carbon fiber plate or two ends of the carbon fiber plate group, and at least one carbon fiber plate or carbon fiber plate group is connected through a prestress tension retainer to form an annular structure I; or the annular structure II is formed by connecting two adjacent anchorage devices with the connecting mechanisms. The device further comprises a detachable prestress tensioning auxiliary mechanism used for applying prestress. The invention further relates to an annular prestress tensioning enhancing or reinforcing method for the reinforcing component. The reinforcing effect is good, the structure is simple, and the method is convenient to operate. The prestress tensioning auxiliary mechanism can be detached and reused after tensioning is completed.
本发明涉及一种环向预应力张拉增强或加固装置，增强或加固对象为柱、筒或管状体，包括桥墩、盖梁、墩柱、索塔、大型筒仓及管道。它采用预应力碳纤维板体外环绕构件对其施加预压应力，能够部分或全部消除荷载产生的拉应力。装置包括碳纤维板或碳纤维板组，其特征在于：在碳纤维板两端或碳纤维板组两端安装锚具，由至少一个碳纤维板或碳纤维板组通过预应力张拉保持架连接构成环向结构Ⅰ；或由两相邻带连接机构的锚具连接构成环向结构Ⅱ。还包括可拆装式的预应力张拉辅助机构用于施加预应力。本发明同时涉及对加固构件的环向预应力张拉增强或加固方法。本发明加固效果好，构造简单，方法操作方便。预应力张拉辅助机构在张拉完成后可拆除并重复使用。
