浅谈预应力锚垫板破坏的预防及处理

The Protection and Treatment of Prestress Anchor Plate Damage

一种锚垫板，在锚垫板的顶板和圆筒筒身间有阶梯连接。

The utility model relates to an anchor mat ; and a step is connected between the top plate of the anchor mat and the cylinder body .

本实用新型是涉及预应力锚具技术领域，尤其是一种圆端面锚垫板。

The utility model relates to an anchor backing plate with a round end surface , which belongs to the technical field of the pre-stressed anchorage device .

锚垫板与索道管定位是斜拉桥施工过程中精度要求很高的测量工作。

The positioning survey of anchor padding plates and cable ducts is a kind of survey work requiring very strict precision in the construction of a cable stayed bridge .

另外，还可将锚垫板固定在施工模板上，在混凝土浇注时能防止锚垫板的位置偏移。

In addition , the anchoring backing board can also be fixed on the construction mould board , and the position offset of the anchoring plate can be prevented during concrete pouring .

该锚垫板结构更优化、锚下应力更小、分布更趋均匀，结构形式简单、重量轻、便于生产制造。

The anchor shim plate has more optimized structure , less stress under the anchor , more uniform distribution , simple structure form and light weight and is convenient for producing and manufacturing .

由张拉端锚具、固定端锚具、索体、防松装置、锚垫板、锚罩、防腐油脂组成。

The utility model consists of a tensioning end anchor , a fixing end anchor , a cable , a loose prevention device , an anchor base plate , an anchor cover and anticorrosive grease .

其特点是包括有一内部有通孔的锚垫板，所述的锚垫板是端面为圆形的锥体结构；

The utility model is characterized in that the utility model comprises an anchor backing plate with a through hole inside , and the anchor backing plate is a conical structure with a round end surface ;

研究表明：锚垫板传递总索力的约20%，其主要作用不是承担索力，而是将索力传给2块锚箱腹板；

The research shows that the pad plate of the anchorage box bears about 20 % of the total cable force , and its main function is not to bear the cable force but to transmit it to the two webs of the anchorage box .

预应力筋张拉包括了波纹管定位，锚下垫板、螺旋筋、预埋，钢绞线张拉准备工作，钢绞线张拉等。

The pre stress contain locating of bellows , spiral bars ' building in , stretching work of steel wire and so on .
