高強(qiáng)度扭剪螺栓的預(yù)緊力-鋼結(jié)構(gòu)的強(qiáng)度螺栓是通過擰緊螺母來實(shí)現(xiàn)的。通常使用扭力法、角度法或扭斷螺栓尾部的方法來控制預(yù)緊力。目前有專用扳手顯示扭力.通過測得的扭矩與螺栓張力的關(guān)系，施加扭矩達(dá)到必要的過張力值。
Preload of high-strength torsion shear bolt - the strength bolt of steel structure is realized by tightening the nut. Torque method, angle method or the method of breaking the bolt tail are usually used to control the preload. At present, there are special wrenches to show torque Through the relationship between the measured torque and bolt tension, the applied torque reaches the necessary over tension value.
轉(zhuǎn)角法轉(zhuǎn)角法分為兩步，一是初始擰緊，另一個(gè)是終擰緊。簡單的說，初擰一般是工人用普通扳手使被連接的部件緊密貼合，而終擰緊是以初始擰緊位置為起點(diǎn)，終擰緊角度為根據(jù)螺栓直徑和層壓板的厚度確定。
Angle method angle method is divided into two steps, one is initial tightening, the other is final tightening. In short, the initial tightening is generally that workers use an ordinary wrench to make the connected parts closely fit, while the final tightening is based on the initial tightening position as the starting point, and the final tightening angle is determined according to the bolt diameter and the thickness of the laminate.
用扳手轉(zhuǎn)動螺母，當(dāng)擰到預(yù)定角度值時(shí)，螺栓的拉力可以達(dá)到所需的預(yù)緊值。為防止高強(qiáng)度螺栓受外界環(huán)境影響而改變扭矩系數(shù)，一般初、終擰緊應(yīng)在同內(nèi)完成。高強(qiáng)度扭剪螺栓的受力特性與一般高強(qiáng)螺栓的受力特性相同，只是施加預(yù)緊力的方法是通過破壞螺栓頭切口的橫截面來控制預(yù)緊力的值。
Turn the nut with a wrench. When it is screwed to the predetermined angle value, the tension of the bolt can reach the required pre tightening value. In order to prevent the high-strength bolt from changing the torque coefficient due to the influence of the external environment, the initial and final tightening should be completed in the same day. The stress characteristics of high-strength torsional shear bolts are the same as those of general high-strength bolts, but the method of applying preload is to control the value of preload by destroying the cross section of the bolt head notch.
摩擦式高強(qiáng)度扭剪螺栓連接完全依靠被連接部件之間的摩擦阻力，摩擦阻力不僅是螺栓的預(yù)緊力，還取決于由以下因素決定的防滑摩擦面連接元件材料及其接觸面的表面處理。看完相信大家已經(jīng)基本明白高強(qiáng)度螺栓應(yīng)該用在什么地方以及正確的操作和擰緊了。
Friction type high-strength torsional shear bolt connection completely depends on the friction resistance between the connected parts. The friction resistance is not only the preload of the bolt, but also depends on the surface treatment of the connecting element material and its contact surface determined by the following factors. After reading, I believe you have basically understood where high-strength bolts should be used and the correct operation and tightening.
