新结构具有可板前更换元件、防振、能良好的接地性能,并便于运输储存。在横梁后焊有钢丝挡住特制的方螺母,网板上则采用弹簧夹固定螺母,这样在更换元件时便不必扶持屏后的螺母。骨架立柱的长孔改为圆孔可减少横梁在骨架上的位移量。同时,将横梁的安装孔改为长孔和改变安装方法,可适应不同尺寸元件的安装;骨架和横梁表面由上漆改为镀锌可保证接地;骨架的装配由焊接改为螺钉装配使运输储存方便。 The new structure has the front plate replacement components, anti-vibration, good grounding performance, and ease of transport and storage. After the beam welded steel wire to block a special square nut, the screen is the use of spring clip retaining nut, so when you replace the components do not have to support the screen after the nut. Skeleton column long hole to a round hole to reduce the beam in the skeleton displacement. At the same time, the installation of the beam hole to change the long hole and change the installation method can be adapted to the installation of components of different sizes; the surface of the skeleton and beams from galvanized to galvanized ground can be guaranteed; skeleton assembly by welding to screw assembly to transport Convenient storage.
