摘要:
A joining element to be anchored in an object with the aid of a thermoplastic material and mechanical vibration includes a proximal end and a distal end that are spaced from one another along an axis of the joining element. A contact face is in the area of the proximal end, the contact face being suitable for being contacted with a vibrating tool for applying, to the joining element, mechanical vibration and a force parallel to the axis. The wall anchoring portion is situated between the proximal end and the distal end, and has a circumferential surface being equipped with a plurality of recesses and radially protruding energy concentrating elements between the recesses. A tubular portion is situated between the proximal end and the distal end and extends distally from the wall anchoring portion.

摘要:
An assembly including a joining element and an object, the object having a first outer layer, a second outer layer, and a middle layer between the first and second outer layers. The object has an opening that extends through the first outer layer and the middle layer, and the joining element is anchored in the opening. The joining element includes a proximal end, a distal end, a contact face in the area of the proximal end, a wall anchoring portion, and a tubular portion. The contact face is engaged by a vibrating tool that applies mechanical vibration and axial force to the joining element. The joining element includes a thermoplastic material at least at the circumferential surface of the wall anchoring portion and at the distal end to anchor the joining element to the first and second outer layers, respectively.

摘要:
A method of anchoring a joining element to a hollow core board with the aid of mechanical vibration. The hollow core board has a first and second outer layers and a middle layer disposed between the outer layers. An opening, including a mouth, is provided in the hollow core board, the opening penetrating the first outer layer and the middle layer. The joining element includes a wall anchoring portion situated between a proximal end and a distal end thereof. A distal end of the wall anchoring portion is positioned into or onto the mouth with a sealing portion on a proximal end of the wall anchoring portion. The wall anchoring portion is forced through the mouth by applying mechanical vibration and a force parallel to the joining element axis, whereby thermoplastic material of the wall anchoring portion is liquefied and pressed into the first outer layer.
