求翻译：梁体张拉在混凝土强度达到设计强度要求及以上且龄期大于7天方可进行。张拉采用YCQ150型穿心式千斤顶，两边同时张拉。张拉时两端加强联系，尽量保持同步。是什么意思？

Tension in the concrete beam strength to meet the design strength and age requirements and more than seven days before proceeding. Tension-type feedthrough jack using YCQ150, both sides of the same tension. Tension at both ends to enhance contact, try to keep pace.

The strength of concrete, Zhang Liang Commonwealth meet the design requirements and more intensity and age greater than 7 days. Zhang, introduced YCQ 150 through the heart in 1000 and two side-chang, simultaneously. When Chang, strengthen their ties with both ends to keep synchronization.

Liang Tizhang pulls in the concrete intensity achieved the design intensity request and above also the stadium is bigger than 7 Arabia to be possible to carry on.Opens pulls uses YCQ150 to put on the heart type hoisting jack, nearby two simultaneously opens pulls.Zhang Lashi the both sides enhanceme

Liang Ti tensile strength design of concrete strength and age greater than 7 days and above would be required. Tensioning of YCQ150 through the core-type Jack, while tension on both sides. Tension ends when closer links, try to keep it synchronized.

Tension in the concrete beam strength to meet the design strength and age requirements and more than seven days before proceeding. Tension-type feedthrough jack using YCQ150, both sides of the same tension. Tension at both ends to enhance contact, try to keep pace.
