一、膨胀螺栓特性简介膨胀螺栓通过螺杆和套筒的开尾,传递挤压应力实现对工件的紧固。开始仅应用于建筑中的室内镶板(天花板、吸音板)、水槽、水箱、吊灯、配电箱、开关、油汽水管路在各种墙面及深柱上的安装。后来在大模板浇制或予制大型镶板等新结构中,也不用予埋大量钢板来进行各种管路的安装,在那里安装支吊架就在那钻孔,然后放置膨胀螺栓,成倍提高效率。通常机械设备的安装,是靠地脚螺拴将设备固定在混凝土基础或地坪上。传统的固
First, the characteristics of the expansion bolt Introduction Expansion bolt through the screw and the end of the sleeve, transfer the extrusion stress to achieve the fastening of the workpiece. It was initially applied to the installation of indoor panels (ceilings, sound-absorbing panels), sinks, tanks, chandeliers, distribution boxes, switches, and oil and gas pipelines in buildings on a variety of wall and deep columns. Later, in new structures such as pouring large plates or prefabricating large panels, it is not necessary to bury a large number of steel plates for the installation of various pipelines, where the support hangers are then drilled, and then the expansion bolts are placed. Increase efficiency. The installation of mechanical equipment is usually based on anchor bolts to fix the equipment on a concrete foundation or floor. Traditional solid
