Launch ATLd disk
1 TAMAÑO OF THE LAUNCH AREA
The launch area of disk consists of the circle of launching inscribed on a platform, a protective cage and fall of the device. The circle will have an inner diameter of 2.50 m (± 5mm).
The sector of fall from disk will have an angle of 34,92º unlimited and a length though related to the level and athletic category launchers to come therein. See drawings
and the following table:
|LAUNCHING ZONE DISC|
|NATIONAL AND INTERNATIONAL||LOWER AND REGIONAL|
|SECTOR ÍNIMA LENGTH
The fall can accurately be drawn by establishing a 12 m distance between two points located on each line of the sector to 20 m from the center of the circle. For each metro progress from the center of the circle, the distance between the lines of the sector is increased by drawing m.véase 0.60
2 OUTER BANDS AND SECURITY
To facilitate the development and vision of the competition by athletes and spectators as well as security measure, bands will be reserved minimum free spaces around the circle and around the perimeter of the sector of falls. Space around the circle of launch and foreign shelf should be limited by a circle concentric with him and 10 m in diameter.
Angle of the sector of crashes (34,92º) must be complemented in the sides by two sectors circular 10th in whose space should not be permitted to access unauthorized persons during the launch by security measure, to avoid it is advisable to place an additional fence at least 1m tall outside the sector. This fence also serves to stop sliding devices.
3 HEIGHT OBSTÁCULOS FREE
The height between the pavement and the nearest obstacle (power lines in outdoor facilities; underside of roof, hang beam, luminaire, through air conditioning in covered facilities) both on the area as on the outer bands, should be entirely free and have a minimum of 12 m. In modules covered with training, will suffice the existence of such free height in the first ten meters of the sector of falls.
SOLAR ORIENTACIÓN 4
The central axis of the circle of launches and falls must be understood in the environment limited by the geographical directorates NO-NE / SE-SO. It must take into account the winds which must be enabled the launch towards both NO-NE as SE-SO.
TYPE OF FLOORING 5
The circle of launches will be a pavement different characteristics in crashes and external gangs. The pavement of the circle must have solved the drainage superficial and deep waters, as well as being rough and not slippery, not abrasive and consistent with security and underfoot, all this in order to be an area suitable for the evolution of the launchers. The circle is typically formed by a concrete floor 25 N / mm2 of resistance to compression, armed with metal mesh and finishing ruleteado to have sufficient adhesion and getting a flat horizontal surface. If used asphalt or other material, have a similar characteristics. At the edge of the circle will be three sewer non-corrosive (for example: tubes of brass OR PVC 20 mm diameter) distributed uniformly and level of the surface of a circle, which will reach permeable infrastructure or are connected to the network of drainage.
The center of the circle of launches from which you measure distances will be signposted and preferably through a brass pipe 4 mm in diameter interior placed at surface level of the circle. See figure
The pavement of crashes sector and its outer bands admitted a maximum outstanding in the direction of launch of 1 per 1000, to enable the evacuation of superficial waters. The pavement must have solved the drainage deep waters, as well as being a deformable enough material to the impact left clear mark, without causing irreparable damage and without having to sign the footsteps of judges and competitors. The pavement will pitch, preferably, for national and international competitions, and for other competitions in its default, clay or ashes.
Artificial lighting is uniform and so that does not cause glare of athletes, judges nor spectators. Mark the standard UNE-EN 12193 “ Illumination of sports facilities ” and will have the following minimum levels of illumination:
|LEVELS OF ILUMINACIÓN MÍNIMOS
ATHLETICS abroad (all activities)
|COMPETICIÓN LEVEL||Horizontal illuminance|
|And med (lux)||Uniformity
And min / Emed
|International and national competitions||500||0.7|
|Local and regional competitions, training high level||200||0.5|
|Training, school sport and recreation||100||0.5|
In launches of disk, hammer and javelin precautions should be taken to ensure the safety of people, because the object launched can leave the illuminated area and be invisible in part of your flight.
For TV broadcasts of color and recording movies requires a vertical illuminance levels of at least 1,000 lux and 1,400 lux in international competitions, however this value can increase with distance from the camera to the object. For more information regarding vertical illuminance, uniformity, color temperature and Performance index of color must consult the mentioned law.
7 ROUTE OF THE AREA
The layout of the area of launches will agree with drawings
Launch areas of disk must be located in full independence and different location of the remaining athletic specialities, except
the possible and partial overlap in their sectors with the fall of launches weight, hammer and javelin.
Launch zones will drive consist of a single circle and sector or by several circles and sectors to allow a simultaneous sports practiced, usually includes two areas of launching for the disk in an athletics track, the location in the track is generally within the semicircles, near the extremes of right opposite the target, the sector of fall is located in the grass area of the interior of the track.
The width of the lines (whitewashed graffiti or) or existing tapes is 5 cm, remain outside areas that delimit. The marking of lines on the platform of the circle must be perfectly acceded, be permanent as well as enrasar with the surface. The marking of lines or tapes on the sector of crashes, must be perfectly acceded and be mobile, unless it is independent character to others.
The full route, you can specify the following details:
7a) median line of the circle: Is the line that restricts the later half of the circle. Is perpendicular to the central axis of the sector declines, coinciding its posterior edge with the center of the circle. line runs and pintará at least 75 cm outside the circle and from both ends with a width of 5 cm and white. Outside the platform the line may be painted wood or some other appropriate material.
7b) lateral Lines: the drops sector will be limited laterally by the sidelines of the sector. The sidelines of drop sector can be accurately establishing a 12 m distance between two points located on each line of the sector to 20 m from the center of the circle. For each metro progress from the center of the circle, the distance between the sector lines will increase in 0.60 m.
The sector aperture (straight separation between the edges of the “ interior lateral lines ”) for a certain distance, must be obtained by multiplying the distance by the factor 0.60.
The launch area of disk normally is combined with the launch of hammer, remained different the diameter of the circle of launch (2.50 m to disk and 2,135 m to hammer) and protective cage.
7c) indicator Lines of distance: Is optional marking over the area of crashes of certain lines that indicate entire distances launch 5 in 5 meters. These lines will be plotted circumference arches in the centre of the circle and 30-35-40-45-50 radios m..... These arches facilitate visually appraising distances by launchers and spectators.
8 THE CIRCLE
The disk must jumping off a circle of the dimensions indicated in point 1. See drawing
Circumference circle limit consist of a flat sheet iron, steel or other material, appropriate thick minimum 6 mm.
The device is typically formed by a series of pieces curves to look jointly to the base platform the circle, so that their faces interiors constitute a perfect circumference.
The device will be set so that its top face is at the same level as the ground outside and 20 mm (± 6 mm) higher than the inner surface of the circle. This device will be ready to resist all weather conditions, and should be painted white on their faces views.
9 BANNERS OR INDICATORS
9th) Banners in the sector: The sector banners are those that complete the extremes of the “ lateral lines of the sector. ” Will Be protected metal corrosion, no metal oxidable or other appropriate material. The banderola will be rectangular and of about 400 x 200 mm. The mast will take 8 mm diameter, rising on the level of the pavement a minimum of 600 mm.
9b) indicators of distance: Can be indicators of distance at the intersection of “ sector lateral lines ” and “ indicator lines of distances. ” Unregulated characteristics.
9c) Banners indicators: Depending on the category of the competition, it should be noted with a banner or special disk distance from the current record, either global, continental, national; it will a banner or indicator hallmark, to bring the best launch of each contestant must be placed over a line or ribbon outside the “ sector lateral lines ”.
The body of the disk can be solid or hole and will be made of wood or another suitable material, with a rim or metal ring, the edge of which must be circular.
The cross-section of the edge is true forming a circle with a radius of about 6 mm round plates Can be embedded metallic at the heart of their faces. Alternatively, the disk can be built without such of metal plates with such that the area equivalent for flat and measures and total weight of disk correspond to the specifications. Both sides of the disk must be identical and indentations will not, nor outgoing tips sharp edges. Have straight profile since the beginning of the curve of the rim or ring up to a circle of a radius of 25 mm minimum and maximum 28.5 mm from the center of the disc.
The profile of the disk is designed as follows: From the beginning of the curve of the rim, thickness from disk will regularly until a maximum thickness D. The maximum value will be achieved on a distance of 25 mm to 28.5 mm from the axis and from disk. From this point until the axis and the thickness of the disk is constant. The upper and lower levels of the disk must be identical and the disk must be symmetrical regarding the axis and as regards rotation. The disk, including the surface of the ring, will not roughness and his uniform smooth will finish in all its parts.
The characteristics of the device, according to the different categories by age, must adhere to the following table:

11 THE CAGE
All launches should be performed from inside a “ cage ” to ensure the safety of spectators, judges and launchers. The design of the “ cage ” depends on constructive characteristics defined by the manufacturer provided they comply with regulatory factors listed below.
These factors are provided when the “ cage ” is located in a stadium with spectators located around the perimeter of the track and field when interior combined with the launch of disk, other athletics. when the “ cage ” or “ cages ”, is present in another situation, (usually areas for training of launches), may be enabled a
The “ cage ” will have to be designed, produced and maintained in such a way that is able to stop a disk of 2 Kg moving at a speed of up to 25 m / s. Likewise shall not be danger rebound in the fixed elements of the “ cage ” hitting the thrower or escaping from the top of the “ cage ”. On the other hand, no disc may make their way through any board of the “ cage ” or below the panels.
11th) dimensions of the “ cage ”: “ cage ” must have at its plant form of Or as shown in the picture
The width of the mouth will be 6 m and will be located at a distance of 7 m in front of the center of the circle of launch. The height of the network pendant or network panels is 4 m at least at its lowest point. The layout of the panels or rear networks will be talque are a minimum of 3 m from the center of the circle.
11b) the network: The network for the cage can be made of string of natural or synthetic fiber appropriate, or alternatively, or highly ductile steel wire tensible. The maximum size of the mesh should be 50 mm for the wire and 44 mm for the network of string.
The minimum extent of the bulk of the wire mesh or depends on the construction of the cage, but the resistance force of the string or cable to breakage must be at least 40 kg. In order to ensure the continued safety of the cage, the network of steel shall be inspected at least every 12 months. The visual inspection is not enough for the string of fiber. instead should be inserted in the network by manufacturers, several pieces of samples (tell-tale) of the string standard.
One of these can check and be checked every 12 months to ensure the continued resistance of the network. The network may be in sections or continuously suspended from a frame or structure well supported and strengthened. It is desirable that the network can be raised and lowered quickly. The network will be suspended without touching points of support for which cannot be beaten by a device launched.
11c) Structure: The structure of the cage consists generally or poles vertical metal brackets, in order to sustain a metallic piece in a horizontal plane that to 4 m in height set the bodies or panels which constitute the cage.
The structure will be sufficiently rigid so that does not deviate from its position due to the weight of the network and / or to the force of the wind.
11d) Subject and editing: The metallic piece will sustentante united solidarity in brackets. The setting to the floor of the media must be preferably through a tube with cap Dock, given of concrete and docking depth (at least 30 cm) to provide adequate rigidity. The whole of the cage will resist the thrust of the wind.
1le) Painted: all the metal elements should be prepared to resist all weather conditions or metal will not oxidable and will be painted a color that contrast perfectly with the background.
Is placed outside the “ cage ” furniture for judges to develop their work.
