1、鋼結(jié)構(gòu)螺栓穿入方向以便利施工為準(zhǔn)，每個(gè)節(jié)點(diǎn)應(yīng)整齊一致。穿入高強(qiáng)度螺栓用扳手緊固后，再卸下臨時(shí)螺栓，以高強(qiáng)度螺栓替換。
1. The penetration direction of steel structure bolts shall be convenient for construction, and each node shall be neat and consistent. After the high-strength bolts are threaded in and tightened with spanners, the temporary bolts are removed and replaced with high-strength bolts.
2、高強(qiáng)度螺栓的緊固，必須分兩次進(jìn)行。
2. The tightening of high strength bolts must be carried out twice.
一次為初擰：初擰緊固到螺栓標(biāo)準(zhǔn)軸力(即設(shè)計(jì)預(yù)拉力)的60%～80%。
One time is the initial tightening: the initial tightening is 60% - 80% of the standard axial force (i.e. the design pretension) of the bolt.
二次緊固為終擰，終擰時(shí)扭剪型高強(qiáng)度螺栓應(yīng)將梅花卡頭擰掉。
The secondary tightening is the final tightening, and the quincunx clip of the high-strength torsional shear bolt shall be removed during the final tightening.
3、待吊裝完成一個(gè)施工段，鋼構(gòu)形成穩(wěn)定框架單元后，開(kāi)始安裝高強(qiáng)度螺栓。
3. After a construction section is completed and the steel structure forms a stable frame unit, high strength bolts are installed.
4、扭剪型高強(qiáng)度螺栓安裝時(shí)應(yīng)注意方向：螺栓的墊圈安在螺母一側(cè)，墊圈孔有倒角的一側(cè)應(yīng)和螺母接觸。
4. Attention should be paid to the direction when installing the torsional shear high strength bolt: the washer of the bolt should be installed on one side of the nut, and the chamfered side of the washer hole should contact with the nut.
5、初擰完畢的螺栓，應(yīng)做好標(biāo)記以供確認(rèn)。為防止漏擰，當(dāng)天安裝的高強(qiáng)度螺栓，當(dāng)天應(yīng)終擰完畢。
5. The bolts after initial tightening shall be marked for confirmation. In order to prevent missed tightening, the high-strength bolts installed on the same day shall be finally tightened on the same day.
6、初擰、終擰都應(yīng)從螺栓群中間向四周對(duì)稱(chēng)擴(kuò)散方式進(jìn)行緊固。
6. The initial and final tightening should be carried out symmetrically from the middle of bolt group to all sides.
7、因空間狹窄，高強(qiáng)度螺栓板手不宜操作部位，可采用加高套管或用手動(dòng)扳手安裝。
7. Due to the narrow space, the high-strength bolt wrench is not suitable to operate the parts. It can be installed by heightening the casing or using a manual wrench.
8、扭剪型高強(qiáng)度螺栓應(yīng)全部擰掉尾部梅花卡頭為終擰結(jié)束，不準(zhǔn)遺漏。
8. Torsion shear type high-strength bolts shall be completely screwed off, and the tail plum blossom clip shall be the end of final screwing, and no omission is allowed.
