定义
Mill Test Reports-MTR’s are required for each component of the bolt asmbly. This report contains the chemical and mechanical requirements of the ASTM designation to which the component was manufactured. It assigns a unique to number to the component.
螺栓装配的每一个组件要有钢厂试验报告-MTR。该报告要求符合按ASTM 标号生产的螺栓的化学和力学要求。这些组件具有一独特的编号。
Bolt asmbly-A bolt asmbly has up to three components, a bolt, a nut and a washer (the number of washers will vary depending on the pre-tensioning method, hole type and connection material). The asmbly consists of a combination of one manufacturing lot for each component. Each combin
ation of components, is assigned a “Bolt Asmbly Lot Number” when any component lot is changed, a new bolt asmbly lot number must be assigned.
螺栓装配- 一套螺栓装配具备三个组件，螺栓，螺帽和垫圈（垫圈的编号根据预紧方法，孔的类型和连接的材料而定）。装配由每一组件的制造批号组合而成。组件的每一种组合被指定为一“螺栓装配批号”。当任何组件批号改变时，必须指定一新的螺栓装配批号。
Snug tight - the snug-tightened condition is defined by the RCSC as “the tightness that is attained with a few impacts of an impact wrench or the full effort of an ironworker, using an ordinary spud wrench, to bring the connected piles into firm contact.”
恰当地拧紧—恰当地拧紧的状态由 RCSC 定义为“拧紧，是由冲击扳手作几次冲击，或由一装配工人采用普通的扳手全力紧固，达到牢固接触。”
Verification Procedure for F1851 & F2280 “Tension Control Bolt” Installation
F1851 和 F2280 “张力控制螺栓”安装验证程序
*Select a minimum of 3 samples from each asmbly lot, that is to be ud in the works. The will be your test asmblies.
从要用于工程中的每一装配批号中最少选择 3 个试样。这些就是你的试验装配件。
*Examine the MTR’s to confirm the test results satisfy the requirements of the specification for each component. Record the lot numbers.
检查试验报告MTR，看每一组件的试验结果是否符合技术条件的要求。记录批号。
*Check bolt asmbly components for manufacturer and grade markings. (attachment #4)
检查装配组件的制造商和等级标记。（附件 #4）
*Confirm that the bolt tension calibrator has been calibrated within the last year.
确认螺栓张力校准器已作校准，并在有效期内。
*Confirm the bolting crew’s procedure and proper u of the installation method.
确认螺栓安装人员对程序和正确安装方法的使用。
Obrved the performance of pre-installation verification steps:
预安装验证步骤：
1.Place the bolt asmbly into the bolt tension calibrator with
washer(S) located as they will be in the steel work.
如同装于钢制工件上那样放置垫圈，将螺栓装配件放入螺栓张力校准器中；
2.“Snug Tighten” the asmbly in the tension calibrator
在张力校准器中恰当地拧紧装配件；
3.Tighten the asmbly with a TC（Torsional Calibrated?）Wrench,
until the spin tip shears off the bolt.
用 TC（校准的扭力）扳手紧固装配件，直至螺栓端部的梅花
卡头断开。
4.Record the pre-tension indicated on the tension calibrator
记录在张力校准器上所指示的预紧力。
5.The pre-tension developed must be equal to or greater than 105%
of the minimum pre-tension required., for the grade and diameter,
of bolt tested (refer to the table on RCSC book)
获得的预紧力，必须等于或大于试验螺栓的等级和直径所要求
的最小预紧力的 105%（参照 RCSC 手册上的表格）。
6.If the actual tension developed in the calibrator is less than 1.05%
（105%）of the minimum specified pre-tension, “the cau(s) shall be determined and resolved before the fastener asmblies are ud in the work.”
如果在校准器中获得的实际拉伸力小于最低的规定的预紧力的105%，则必须在将装配件用于钢结构之前确定原因并解决。
