扭矩扳手工作原理：是依據(jù)梁的彎曲原理、扭桿的彎曲原理和螺旋彈簧的壓縮原理而設(shè)計的，能測量出作用在螺母上的力矩大小。扭矩扳手又叫力矩扳手、扭力扳手、扭矩可調(diào)扳手，是扳手的一種，一般分為三類：手動力矩扳手、氣動扭力扳手和電動力矩扳手。扭矩扳手有一根長的彈性桿，其一端裝著手柄，另一端裝有方頭或六角頭，在方頭或六角頭上套裝一個可換的套筒，用鋼珠卡住。在頂端上還裝有一個長指針?？潭劝骞潭ㄔ诒?，每格刻度值為1N。
Working principle of torque wrench: it is designed according to the bending principle of beam, the bending principle of torsion bar and the compression principle of spiral spring, and can measure the torque acting on the nut. Torque wrench, also called torque wrench, torque wrench and torque adjustable wrench, is a kind of wrench, which is generally divided into three categories: manual torque wrench, pneumatic torque wrench and electric torque wrench. The torque wrench has a long elastic rod, one end of which is equipped with a handle, and the other end is equipped with a square head or hexagonal head. A replaceable sleeve is sleeved on the square head or hexagonal head and clamped with a steel ball. There is also a long pointer on the top. The scale plate is fixed on the handle base, and the scale value of each grid is 1n.
什么是鋼結(jié)構(gòu)扭剪螺栓。一般來說，它是由熱處理高強度鋼35CrMo35碳鋼材料等制成，可分為8.8級和10.9級，與普通螺栓不同，螺栓必須在8.8級以上。
What is steel structure torsional shear bolt. Generally speaking, it is made of heat-treated high-strength steel 35crmo35 carbon steel, which can be divided into grade 8.8 and grade 10.9. Unlike ordinary bolts, bolts must be above grade 8.8.
選擇時無需提出鋼種和鋼種要求。 摩擦式連接是鋼結(jié)構(gòu)工程中常用的一種。鋼結(jié)構(gòu)扭剪螺栓從受力特性上可分為摩擦式連接和壓力式連接。 鋼結(jié)構(gòu)扭剪螺栓承壓連接的連接面只需進行防銹處理即可。 然而，鋼結(jié)構(gòu)扭剪螺栓摩擦式具有連接緊密、受力好、抗疲勞、適合承受動載荷的優(yōu)點。但連接面需做摩擦面處理，一般采用噴砂處理，噴砂后涂無機富鋅漆。
Steel grade and steel grade requirements are not required for selection. Friction connection is a kind of common used in steel structure engineering. The torsional shear bolt of steel structure can be divided into friction connection and pressure connection. The connection surface of steel structure torsion shear bolt pressure bearing connection only needs to be treated with rust prevention. However, the friction type of torsional shear bolt in steel structure has the advantages of tight connection, good stress, fatigue resistance and suitable for bearing dynamic load. However, the connecting surface needs to be treated with friction surface. Generally, sand blasting is adopted, and inorganic zinc rich paint is applied after sand blasting.
鋼結(jié)構(gòu)扭剪螺栓可分由于螺栓結(jié)構(gòu)和施工方法不同，分為大六角頭高強螺栓和扭剪高強螺栓。 大六角頭型與普通六角頭粗螺栓相同。扭剪式螺栓頭與鉚釘頭類似，但扭剪式螺紋端裝有梅花夾頭和可控制擰緊扭矩的環(huán)形槽這個區(qū)別需要注意。
Steel structure torsional shear bolts can be divided into large hexagon high-strength bolts and torsional shear high-strength bolts due to different bolt structures and construction methods. The large hexagon head type is the same as the common hexagon head thick bolt. The torsional shear bolt head is similar to the rivet head, but the difference between the torsional shear thread end equipped with a plum blossom collet and an annular groove that can control the tightening torque needs attention.
一個鋼結(jié)構(gòu)扭剪螺栓連接副包括三個部分：螺栓、螺母和墊圈。高強螺栓的結(jié)構(gòu)和布置要求與普通螺栓相同。 那么一定要按照規(guī)范使用。大六角頭只能用8.8高強螺栓，扭剪型高強螺栓只能用10.9高強螺栓。
A steel structure torsion shear bolt connection pair consists of three parts: bolt, nut and washer. The structure and layout requirements of high-strength bolts are the same as those of ordinary bolts. Then it must be used according to the specifications. Only 8.8 high-strength bolts can be used for large hexagon head and only 10.9 high-strength bolts can be used for torsional shear high-strength bolts.
