地脚螺栓的作用,是把设备与基础连结成为一个整体,使设备能够正常运转。因此,地脚螺栓在设备安装和使用过程中。要承受两种拉应力:一种是在安装设备时,需要对地脚螺栓施加很大拧紧力才能把设备固定牢固,根据设备安装规程的要求,地脚螺栓的拧紧力为钢材屈服强度的0.6～0.7倍(即1680公斤力/厘米~2左右)的时候,才能达到技术要求;另一种是设备使用时,设备的动力作用和倾翻力矩在地脚螺栓中产生的拉应力。过去常用预埋螺栓固定地脚螺栓方法,需要消耗大量的钢材。为了提高经济效益,我们用环氧砂浆粘接地脚螺栓,不仅节约钢
The role of anchor bolts, the equipment and the basis of the link as a whole, so that equipment can operate normally. Therefore, the anchor bolts in the equipment installation and use. To bear two kinds of tensile stress: one is the installation of equipment, the need for a great tightening force on the anchor bolts to the equipment fixed, according to equipment installation requirements, the anchor bolt tightening force of steel yield strength of 0.6 ~ 0.7 times (that is, 1680 kg / cm ~ 2 or so) in order to meet the technical requirements; the other is the tensile stress generated in the anchor bolt when the equipment is used, the dynamic effect of the equipment and the tilting moment. In the past often used to fix anchor bolts bolt method, you need to consume a large amount of steel. In order to improve economic efficiency, we use epoxy mortar bonding anchor bolts, not only save the steel
