查询词典 adhibition

To ensure close adhibition of connecting board, screwing should start from center to outside, that is, screwing from enlarged center to skirting area. To avoid coating's influence on tensile force, screwing work should be finished on one day. And to decrease prestress' difference of high-tension bolt, bolt screwing runs in two steps: primary screwing and final screwing. For large-scale joint with great amount of bolts demands a second screwing.

为使被连接板叠密贴紧，应从螺栓群中央顺序向外施拧，即从节点中刚变大的中央按顺序向下受约束的边缘施拧，为防止高强度螺栓连接副的表面处理涂层发生变化影响拉力，应在当天终拧完毕，为减少先拧后拧的高强度螺栓预拉力的差别，其拧紧必须分为初拧和终拧两步进行，对于大型节点，螺栓数量较多，则需要增加一道复拧工序。
