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. |
USERDEFINED
|
User-defined element assembly. |
NOTDEFINED
|
Undefined element assembly. |
