Definitions

• the invention relates to an anchoring device, in particular for a safety gear of a runway, with the features of the preamble of claim 1, a safety gear with such an anchoring device and a method for installing at least one such anchoring device in such a system.
• Generic capture systems are used to stop aircraft that threaten to roll over a runway out. A retraction area of the capture system is formed ramp-shaped. The wheels of the aircraft break through the usually consisting of concrete thin ceiling of the capture system and remain in the bulk material (often glass concrete ballast) stuck.
• the ground on which the safety gear is arranged often consists of asphalt or concrete.
• Aircraft Arresting System Aircraft Arresting System
• EAS Engineered Materials Arresting System
• Bulk material (as described, for example, in US 2016 097170 A1) is arranged under a cover (which is produced, for example, from cast concrete).
• Such capture systems are located in the end of a runway and are thus flown over by landing and takeoff aircraft, resulting in a suction effect.
• anchoring devices are used, which initiate the resulting from the suction tensile forces in the ground.
• geogrids As anchoring devices hitherto so-called geogrids have been used, which are fastened on the ground and shed after introduction of the bulk material with the ceiling.
• This system has a number of disadvantages:
• the anchoring effect can not be controlled non-destructively.
• a lack of anchoring effect can z.
• B. result from a locally insufficient connection of the geogrid with the material of the ceiling.
• the dimensioning of the geogrid must be exactly matched to the extension (in particular the height profile) of the safety gear. Inaccuracies in alignment lead to a faulty connection of the geogrid with the material of the ceiling.
• the anchoring device must be installed together with the safety gear. There is no retrofitting possible.
• the anchoring force is not selectable, but results from the extent of the connection of the geogrid with the ceiling. A change in the anchoring force after installation is not possible without destroying the capture system.
• the object of the invention is to provide a generic anchoring device, a capture system with such an anchoring device and a method for installing such an anchoring device in such a capture system in which at least some, preferably all, of the problems discussed above are avoided.
• the anchoring devices according to the invention offer a number of advantages: Because the anchor for securing the ceiling of the safety gear is accessible from the outside, a simple check can be carried out without destroying the ceiling. For example, a visual check can be made as to whether the anchor is sufficiently connected to the ceiling of the safety gear. It can be checked with which tensile forces the anchor is loadable, without the connection with the ceiling dissolves.
• the anchoring device according to the invention acts selectively, no vote must be made with an extension of the safety gear, it must only be provided more or less anchoring devices.
• the individual anchoring devices are spaced apart and act independently.
• Retrofitting existing fishing facilities is, in particular in such fishing systems, which already have anchoring devices in the form of geogrids, in a simple manner possible. Only appropriate holes in the ceiling, the bulk material and the substrate must be prepared. Then the assembly of the anchoring device according to the invention can take place.
• the anchoring force is selectable by a bias voltage between the fastening device and anchor is applied over the at least one connecting part.
• a change in the anchoring force (for example, to compensate for a gradual slipping out of the fixture from the ground or temperature-related changes in the distance between the fixture and anchor) after installation is possible without destroying the capture system by changing the bias.
• the ceiling of the capture system may be formed in the form of plate-shaped segments due to their size.
• the punctually arranged anchoring devices according to the invention ensure a correct alignment with each other of the plate-shaped segments even under suction.
• the anchoring devices according to the invention are designed for a load of 2 to 6 kilonewtons each.
• the anchor can have a body that does not necessarily have to have a plate-shaped section.
• the body can be made of metal or plastic.
• At least one armature has a plate-shaped anchoring part, with which the armature in the assembled state can be pressed against the ceiling of the capture system. This results in a surface registration of the tensile forces in the ceiling of the safety gear and a minimum order in height on the ceiling in the case of a superposed arrangement. Is a seal of the ceiling provided the sealing process is facilitated and the anchor is automatically sealed with.
• At least one anchor has a cup-shaped portion, which preferably protrudes from the anchoring part on one side of a plate-shaped anchoring part. This allows a recessed arrangement of that position at which the connecting part is or is connected to the armature. Preventing this position over the anchor is thus avoided and sealing material (if a seal of the ceiling of the trap is performed) can completely cover the anchor in one operation.
• the position at which the connecting part is or is connected to the armature could be arranged on an upper side (in the assembled state) of the armature and possibly covered by a cover.
• the pot-shaped portion has a passage opening for the at least one connecting part, wherein the passage opening is preferably provided with a screw thread.
• a screw thread is provided, this can be used for connecting the connecting part to the armature and applying a bias voltage between the connecting part and the armature.
• the anchor can also (without having a plate-shaped anchoring part) be formed cup-shaped as a whole.
• a cover is releasably connectable to the at least one anchor.
• an at least substantially continuous surface for sealing the ceiling of the safety gear is created or prevents penetration of sealing material in a cup-shaped portion of the armature.
• At least one connecting part in the form of a - preferably - flexible traction means is formed.
• a traction device is ideal for absorbing tensile forces and can be prestressed.
• a flexibility of the traction means allows yielding under a pressure load as occurs, for example, when entering an aircraft in the safety gear.
• the traction means in the case of a pressure load as occurs when retracting an aircraft in the trap system, ruptures.
• Suitable materials for the flexible traction means are z. As metals and plastics.
• a clamping device for applying a selectable bias between armature and connecting part.
• the application of the bias can, for. B. by applying a torque, which acts on a screw or a gear of the clamping device.
• a pulling force could be applied to the connecting part and a fixation of the connecting part to the armature be made in this state.
• Another possibility is the use of the wedge principle by means of a wedge and an inclined plane of the tensioning device, d. H. a path controlled application of the bias voltage.
• an energy storage device eg a defined tension spring).
• At least one fastening device is designed as undercut dowel, expansion dowel or adhesive anchor. These can easily be subsequently connected to the ground. An undercut dowel or expansion dowel can also be replaced.
• the at least one fastening device may consist of a metal or plastic.
• the anchoring device may physically be in the form of the three parts armature, connecting part and fastening device (possibly pre-connected at least in relation to two parts, in particular, the connecting part with the armature or the fastening device may be vorverbunden).
