Strengthening System Review / 加固体系复核

External prestressing is not just adding tendons. The anchorage, deviator, force path, site access and long-term protection must work as one system. 体外预应力不是简单加钢束，锚固、转向、传力路径、施工空间和长期防护必须成体系。

01 Concept Strategy / 概念策略

Define whether external prestressing is suitable before detailed drawings. 先判断是否适合体外预应力，再进入详图。

02 Tendon Route / 钢束路径

Review tendon geometry, deviation points, clearance and conflict with existing structure. 复核钢束线形、转向点、净空和既有结构冲突。

03 Anchorage & Deviator / 锚固与转向

Review local force transfer, reinforcement need and construction feasibility. 复核局部传力、补强需求和施工可行性。

04 Implementation Risk / 实施风险

Review jacking access, temporary works, corrosion protection and monitoring needs. 复核张拉空间、临时措施、防腐和监测需求。

适用项目

Existing beam strengthening / 既有梁加固

Capacity improvement with limited demolition. 少拆改条件下提升承载力。

Bridge strengthening / 桥梁加固

External tendon systems for bridge rehabilitation. 桥梁修复中的体外钢束体系。

Change of building use / 建筑功能改变

Strengthening when service load increases. 使用荷载增加后的结构加固。

First Review Evidence / 初步复核资料

The first step is to decide whether external prestressing is structurally meaningful and buildable. 第一步是判断体外预应力是否有结构意义并且现场可实施。

Existing structural drawings / 原结构图
Inspection or defect information / 检测报告或缺陷资料
Load increase or service requirement / 荷载提升或使用要求
Site access, anchorage space and photos / 施工通道、锚固空间和现场照片

Do you have an existing structure to strengthen?

Submit drawings, defect photos and load requirements first. We will check whether external prestressing should be considered. 先提交图纸、缺陷照片和荷载要求，我们会判断是否适合体外预应力路线。
