橋梁扳手都有些哪些種類？

What kinds of bridge wrenches are there?

每一個橋梁工程都不是統(tǒng)一的工藝。所以橋梁專用扳手在各所大橋中的應(yīng)用也是盡不相同，橋梁上用的除了電動扳手還有哪些呢？在橋梁建設(shè)中，有很多種類，橋梁專用扳手主要應(yīng)用于鋼箱梁橋梁以及鋼桁梁橋梁。橋梁專用扳手有初緊電動扭矩扳手、終緊電動扭矩扳手、手動扭矩扳手、還有軸力扭矩儀、軸力計等。橋梁上用到的高強螺栓型號不同對應(yīng)的扭矩扳手型號也不一樣，還有用于檢測螺栓和校驗的工具。

Every bridge project is not a unified process. Therefore, the application of special bridge wrenches in each bridge is also different. What other wrenches are used on bridges besides electric wrenches? In bridge construction, there are many kinds of special wrenches for bridges, which are mainly used in steel box girder bridges and steel truss bridges. Special wrenches for bridges include electric torque wrenches for initial tightening, electric torque wrenches for final tightening, manual torque wrenches, axle force torque meters, axle force meters, etc. Different types of high-strength bolts used on bridges correspond to different types of torque wrenches, as well as tools for testing bolts and calibration.

電動扳手怎么選型號?

工地上腳手架常用的19號,22號的扳手，常用的是22的套頭。

19 # and 22 # wrenches are commonly used for scaffolds on the construction site, and 22 # socket is commonly used.

M33~M100的螺栓，扭矩在3000Nm以上（ 多用于風(fēng)電行業(yè)）

M33~M100 bolts, torque above 3000Nm (mostly used in wind power industry)

M16~M30的螺栓，扭矩300~3000Nm,（多用于鋼結(jié)構(gòu)、橋梁等行業(yè)）

M16~M30 bolts, torque 300~3000Nm, (mostly used in steel structure, bridge and other industries)

M6~M16的螺栓，扭矩一般在300Nm以下

The torque of M6-M16 bolts is generally below 300Nm
