Embodiment Construction

[0024] figure 1 An insert, generally indicated at 10, is shown viewed from above. The insert 10 is a part that allows the attachment of other components, such as brackets, to a sandwich component with a honeycomb core, so that forces can be transmitted between the sandwich component and the other component. The insert thus constitutes a so-called connection point between the sandwich component and the other component to be attached thereto.

[0025] The insert 10 has a hollow cylindrical inner sleeve 12, the through hole 14 of which can be designed as a threaded hole, for example. A similarly hollow cylindrical outer sleeve 16 is arranged concentrically and radially spaced relative to the inner sleeve 12, the inner side of which is connected to the inner sleeve by a plurality (in this case six) of radial webs 18 12 outside. The basic structure of the insert 10 is formed by the inner sleeve 12 , the outer sleeve 16 and the web 18 connecting the two sleeves 12 , 16 .

Abstract

An insert (10) for a sandwich component (30) having a honeycomb core (31) has an inner hollow-cylindrical sleeve (12) . To improve the force-transmitting ability between the insert (10) and the sandwich component (30) , the insert (10) further has an outer sleeve (16) which is connected to the inner sleeve (12) by means of a plurality of radial webs (18) forming a plurality of axial chambers (20). Introduction of a push-in part (32) into the chambers (20) , cause the anchor elements to exit, with their pointed end (24) in front, through exit openings (28) radially out of the chambers (20) .

Description

technical field [0001] The invention relates to an insert for a sandwich assembly with a honeycomb core. Sandwich components of this type are light in weight and high in stiffness, for which reason they are frequently used, in particular in aircraft construction. For example, luggage compartments, partitions, etc. in the cabin area of ​​passenger aircraft are manufactured from such sandwich components. Background technique [0002] Sandwich assemblies commonly used in aircraft construction consist of two thin so-called prepregs as outer skins with a honeycomb structure in between, which may consist, for example, of paper impregnated with synthetic resin. Prepregs are fiberboards impregnated with synthetic resins. Obviously, with this construction, it is not possible to fasten structural elements such as brackets to the sandwich assembly by conventional connection techniques (for example by screws), since conventional connection means cannot obtain sufficient support on the...
