Support refers to the components used to support and secure equipment. The weight of the main electrical equipment, accessories, and materials, and when installed outdoors, the equipment also needs to withstand wind and seismic loads. According to the form and installation position of the equipment shell, i.e. the container itself, there are vertical, horizontal, and spherical container supports. Vertical supports can be divided into suspension type, support type, and skirt type supports. Horizontal bearings can be divided into branch bearing, ring bearing, and saddle bearing. Spherical container supports can be branched column, skirt, and semi buried supports. Due to the concentrated load effect of the support reaction force. There is a significant local stress at the connection between the support and the container, and adding a pad can reduce the stress at this point. In addition, the use of tangential support can prevent the support from generating additional torque on the container
Support Type
Overview
The structural type of support is mainly determined by the type of the container itself and the shape of the support, and is usually divided into three types: vertical support, horizontal support, and spherical container support.
. Vertical supports are further divided into suspended supports, supported supports, supported feet, supported legs, skirt supports, etc; Horizontal supports are divided into saddle type supports, ring seats, and leg type supports, etc; Spherical container supports include branch column, skirt, semi buried, and V-shaped supports. There are many types of bridge bearings, and commonly used bearings can be selected based on the bridge span, support point reaction force, and requirements for the height of the bearing structure. There are several types of bearings:cushion bearings
simple bearings made of asphalt felt, asbestos mud, or cement mortar cushion layers. For simply supported slabs or beam bridges with spans below 10m, special bearings may not be installed, and the slabs or beams can be directly placed on the above-mentioned cushion layers. The deformation performance is poor, and in addition to setting a cushion layer, the fixed support also uses anchor bolts to connect the upper and lower structures
