5.4.2.7.2 Type values
Type
Description
ABUTMENT
A bridge abutment built up of walls, beams, slabs etc.
ACCESSORY_ASSEMBLY
Assembled accessories or components.
ARCH
A curved structure.
BEAM_GRID
Interconnected beams, located in one (typically horizontal) plane.
BRACED_FRAME
A rigid frame with additional bracing members.
CROSS_BRACING
A Structural linear member or assembly of members inside a box girder or between girders, typically on a pier, to resist lateral forces and transfer them to the support.
DECK
A platform (such as floor or bridge deck) built up of beams, slabs.
DILATATIONPANEL
Device which permits longitudinal relative rail movement of two adjacent rails, while maintaining correct guidance and support.
ENTRANCEWORKS
An assembly forming the support structure of a chamber (lock, dock) gate and associated elements, plus the containment of operational equipment.
GIRDER
A beam-like superstructure, such as bridge main girder extending between abutments and piers built up of beams, braces (as Members) etc. - may also be an aggregation of girder segments.
GRID
A framework of spaced cables or bars that are parallel to or cross each other.
MAST
An assembly of plates, members, cables or fasteners that form a vertical structure for the support or mounting of other equipment such as lights, sonar or wireless transmitters.
PIER
An intermediate support e.g. in a bridge, built up of walls, columns, beams etc.
PYLON
A vertical structure supporting cables in suspended or stayed structure.
RAIL_MECHANICAL_EQUIPMENT_ASSEMBLY
A complex assembly made up of several components like blocking device, speed regulator, bias loaded inspector, track scale or controllable retarder.
REINFORCEMENT_UNIT
Assembled reinforcement elements.
RIGID_FRAME
A structure built up of beams, columns, etc. with moment-resisting joints, such as gantry
SHELTER
A structure, fairly quick to setup, move or dismantle, used to give protection, especially from the weather or intrusion.
SIGNALASSEMBLY
An assembly to physically aggregate together one or more signal instances (and also sign instances) including any supporting structural elements such as a simple pole or a rigid frame gantry.
SLAB_FIELD
Slabs, laid out in one plane.
SUMPBUSTER
An obstacle (with oil catchment basin) installed typically in a bus lane to prevent other traffic with lower ground clearance from using it. Also Sump breaker or Sump trap.
SUPPORTINGASSEMBLY
An assembly intends to support Overhead Contact Line System. It includes foundation, supporting elements and suspension assembly.
SUSPENSIONASSEMBLY
A complex assembly of components used to suspend elements or cable segments.
TRACKPANEL
Trackwork ensuring the support and guidance of a vehicle along a route. It consists of assembly of rail, sleepers and fastenings.
TRACTION_SWITCHING_ASSEMBLY
A common assembly used to insure the switching function. It is composed of switches, control instruments and other components.
TRAFFIC_CALMING_DEVICE
A structure on the carriageway to control the speed of vehicles.
TRUSS
A structure built up of members with (quasi) pinned joint.
TURNOUTPANEL
Trackwork ensuring the support and guidance of a vehicle along any given route among various diverging or intersecting tracks.
