1.需要對大角高強度螺栓來進行檢查。需要采用小錘敲擊法對高強度螺栓來進行普查，防止漏擰。這種方法主要是用手指夾住螺母的一個邊，按的位置如果手指感到輕微的顫動，應該盡量靠近螺母近墊圈的地方，然后采用0.3~0.5千克重的小錘進行敲擊螺母的另一邊，如果手指感到輕微的顫動就算是合格，顫動比較大的話就是可能漏擰或者欠擰，完全不顫動的話就是超擰。
1. large angle high-strength bolts shall be inspected. It is necessary to use a small hammer to knock high-strength bolts for general survey to prevent missing tightening. This method is mainly to clamp one side of the nut with the finger. If the finger feels slight vibration, it should be close to the nut near the washer as far as possible, and then use a small hammer weighing 0.3~0.5 kg to knock the other side of the nut. If the finger feels slight vibration, it is qualified. If the vibration is large, it may be missing or under tightening, and if there is no vibration at all, it is over tightening.
2.扭剪型高強度螺栓連接副的質量控制和驗收。因為它的結構特點，在施工中梅花干的部分承受的是反扭矩，所以梅花頭部分擰斷。也就是說螺栓連接副已經施加了相同的扭矩。所以在檢查的時候只需要目測梅花頭擰斷就算是合格。但是在個別部位的螺栓無法使用專用的扳手，則需要按照相同直徑的高強度大六角螺栓的檢驗方法來進行。在高強度螺栓安裝和施工的過程中，難免會有所忽視或者遺漏。所以在安裝完成之后需要對其進行詳細的檢查，那么在檢查的時候我們應該需要注意哪些內容呢？
2. quality control and acceptance of torsional shear high-strength bolt connection pair. Because of its structural characteristics, the plum blossom stem bears the reverse torque during construction, so the plum blossom head is broken. That is to say, the same torque has been applied to the bolt connection pair. Therefore, it is only necessary to visually check that the plum blossom head is broken during inspection. However, if a special wrench cannot be used for bolts at some parts, the inspection method for high-strength large hexagon bolts with the same diameter shall be followed. In the process of installation and construction of high-strength bolts, it is inevitable to neglect or omit. Therefore, it is necessary to check the installation in detail. What should we pay attention to when checking?
1.指派的質檢員按照規范的要求對整個高強度螺栓安裝工作的完成情況進行認真的檢查，然后將檢查結果記錄在檢驗報告中，然后將檢查報告交送給項目負責人進行審批。
1. appoint professional quality inspectors to carefully inspect the completion of the installation of the whole high-strength bolt according to the requirements of the specification, and then record the inspection results in the inspection report, and then submit the inspection report to the project leader for approval.
2.扭剪型高強度螺栓在終擰完成之后進行檢查時，以擰掉尾部為合格，螺栓絲扣外露應該為2~3扣，其中允許有10%的螺栓絲扣外露1，扣或4扣。
2. when the torsional shear high-strength bolts are inspected after the final tightening, it is qualified to screw off the tail. The exposed bolt threads should be 2~3 threads, of which 10% of the bolt threads are allowed to be exposed by 1, 4 threads.
3.對于因為構造原因而采用扭矩扳手擰緊的高強度螺栓，那么應該使用經過核定的扭矩扳手，用轉角法來進行抽檢。
3. for high-strength bolts tightened by torque wrench due to structural reasons, the approved torque wrench shall be used for sampling inspection by angle method.
4.扭剪型的高強度螺栓連接副終擰之后，除了因為構造原因無法使用專用扳手終擰掉梅花頭者外，沒有在終擰中擰掉梅花頭的螺栓數不應該大于該節點螺栓數的5%。
4. after the final tightening of the torsional shear type high-strength bolt connection pair, except for those who cannot use a special wrench to remove the Torx head due to structural reasons, the number of bolts that do not remove the Torx head in the final tightening shall not be greater than 5% of the number of bolts at this node.
5.高強度螺栓的安裝檢查需要在終擰一個小時以后，但是需要在24小時之前完成。
5. the installation inspection of high-strength bolts shall be completed one hour after final tightening, but 24 hours before.
6.對于采用扭矩扳手擰緊的高強度螺栓，在終擰結束之后，檢查漏擰，欠擰的應該采用0.3~0.5千克重的小錘來逐個敲檢，如果發現有欠擰，漏擰應該進行補擰，超擰的話應該更換。
6. for high-strength bolts tightened with torque wrench, after the final tightening, check the missing tightening. For those under tightened, use a small hammer weighing 0.3~0.5 kg to knock one by one. If there is any under tightening, the missing tightening should be supplemented. If there is over tightening, it should be replaced.
7.要做好高強度螺栓的檢查記錄，在整理之后歸入技術檔案。
7. the inspection records of high-strength bolts shall be made, which shall be included in the technical archives after sorting.
雖然說現在的鋼結構發展很快，但是對于一些基礎施工的方式方法還不是很了解。現在就針對大六角頭的高強度螺栓的連接施工中，是需要針對不同的扭矩系數采取不同的方式方法來進行施工，那么我們在工地上常見的施工方法一般由哪些呢？今天小編就來詳細給大家介紹一下。
Although the current steel structure is developing rapidly, some methods of foundation construction are not well understood. Now, in the connection construction of high-strength bolts with large hexagon head, different ways and methods need to be adopted for different torque coefficients. What are the common construction methods on the construction site? Today, I will give you a detailed introduction.
