6.3.2.2.2 Type values
Type | Description |
---|---|
ANCHORPLATE
|
An accessory consisting of a steel plate, shear stud connectors or welded-on rebar which is embedded into the surface of a concrete element so that other elements can be welded or bolted onto it later. |
BIRDPROTECTION
|
A device that prevents a sitting down of birds at electrically critical points and thus birds are protected against electrical shocks and disturbances by short circuit are avoided. |
BRACKET
|
An L-shaped or similarly shaped accessory attached in a corner between elements to hold them together or to carry a secondary element. |
CABLEARRANGER
|
A cable arranger is a flexible accessory or a part of a component placed around cables to arrange and minimize flexing of them at the point where it is placed. |
ELASTIC_CUSHION
|
A track elastic cushion is a kind of layer set on grooved sides of a concrete base, which is used for mitigating the impact of longitudinal and lateral load on track structures. A track elastic cushion shall only appear in ballastless track structures. |
EXPANSION_JOINT_DEVICE
|
Assembly connection element between construction elements to allow for thermic differential expansions. |
FILLER
|
Sealant, gap filler rod, packing material or other used to close a gap. |
FLASHING
|
Construction material used to manage the passage of water around objects. |
INSULATOR
|
A device designed to support and insulate a conductive element. Note: definition from IEC 151-15-39. |
LOCK
|
A lock is a mechanical or electronic fastening device that is released either by a physical object (e.g., key, fingerprint, RFID card, security token etc.), by supplying secret information (e.g., number permutation, password), or by a combination thereof. |
PANEL_STRENGTHENING
|
A component that minimizes pump effects of the substructure. |
POINTMACHINEMOUNTINGDEVICE
|
Point machine mounting device. |
POINT_MACHINE_LOCKING_DEVICE
|
Point machine locking device. |
RAILBRACE
|
A rail component that prevents rails from tipping and twisting. |
RAILPAD
|
A non-metallic pad placed between rail and baseplate or rail and sleeper, bearer or slab. Note: definition from EN 13481-1. |
RAIL_LUBRICATION
|
A device that prevents wearing of the rails throughout the flange of wheel to reduce noise emissions. It is often located at inner side of the outer rail in a curve or near turnouts (depends on function wearing or noise reduction). |
RAIL_MECHANICAL_EQUIPMENT
|
A rail mechanical equipment is a mechnical equipment installed at railside, like blocking device, speed regulator, bias loaded inspector, track scale or controllable retarder. |
SHOE
|
A column shoe or a beam shoe (beam hanger) used to support or secure an element. |
SLIDINGCHAIR
|
A component which supports and retains the stock rail and a flat surface upon which the foot of the switch rail slides. |
SOUNDABSORPTION
|
A component in the track for sound absorption and may also absorb vibrations. It is often used in combination with slab tracks. |
TENSIONINGEQUIPMENT
|
An equipment used to maintain the tension of conductors or cables. |
USERDEFINED
|
User-defined accessory. |
NOTDEFINED
|
Undefined accessory. |
