A method for Inserting and fixing a mounting insert into a lightweight sandwich panel. The panel comprises a core layer and two cover layers that are applied to opposing main surfaces of the panel. A recess extends into the depth of the core layer of the panel. The mounting insert is inserted into the recess and is adhesively bonded therein. The bottom of the recess extends to a depth of the core layer material that extends further than the longitudinal extension of the recessing section to be inserted. When adhesively bonding the mounting insert, an air gap remains between an end face of the recessing section and the bottom of the recess. No adhesive is placed into the air gap. The air gap ensures a decoupling so that any applied tensile forces are no longer transferred to the cover layer opposite and the undesired formation of dents is avoided.

1. A method for inserting and fixing a mounting insert into a lightweight sandwich panel by means of an adhesive bonding technique, said method comprising the steps of: providing said lightweight sandwich panel comprising a core layer having a first surface and an opposed second surface; and two cover layers, wherein each cover layer is applied to a different one of the first and second surfaces;providing said mounting insert; wherein said mounting insert includes a recessing section;removing material from the core layer of the lightweight sandwich panel to form an opening therein; wherein the opening has a depth that extends into a depth of the core layer such that the depth of the core layer is greater than the depth of the opening and a region of the core layer remains between a bottom of the opening and the cover layer applied to the second surface;filling the opening with a filler material;bonding the filler material to the lightweight sandwich panel that bounds the opening;subsequently removing material from the filler material to form a recess in said filler material, the recess having a depth less than the depth of the filler material;inserting the recessing section of the mounting insert into the recess defined in the filler material in the lightweight sandwich panel; wherein an end face of the recessing section is opposed to the bottom of the recess;defining an air gap between the end face of the recessing section and the bottom of the recess;adhesively bonding the mounting insert to the lightweight sandwich panel, wherein no adhesive is placed into the air gap. 2. The method according to claim 1, further comprising providing a support section on the mounting insert; wherein the support section has a lateral extension in a transverse direction, transverse to a longitudinal extension of the recessing section, and the lateral extension is greater than an extension of the recessing section in the transverse direction, and the lateral section is also greater than the extension of the recess in said transverse direction; placing the support section on the cover layer applied to the first surface of the lightweight sandwich layer when the recessing section is inserted into the recess;surface-bonding the support section to the cover layer applied to the first surface or to the core layer. 3. The method according to claim 1, wherein the recess is formed in the core layer and the mounting insert is adhesively bonded to the core layer before a cover layer is applied to the first surface of the core layer, and that, subsequently, the cover layer is applied to the first surface of the core layer and is bonded to the core layer. 4. The method according to claim 1, wherein the core layer has a honeycomb structure. 5. The method according to claim 1, wherein the filler material used is a porous curing material. 6. A mounting insert for installation into a lightweight sandwich panel, said mounting insert comprising: a recessing section for recessed insertion into a recess defined in the lightweight sandwich panel, wherein the recessing section has a longitudinal extension in a first direction;a collar is formed and continues from a first end face of said recessing section, said collar being shaped as a circumferential plate that extends in a direction transverse to the longitudinal extension; said collar overhanging the recessing section; wherein the extension of the collar in the transverse direction is at least 1.5 times an extension of the recessing section in the transverse direction, andwherein the recessing section includes a second end face that is located opposite the first end face; and the second end face has a uniform extension in the transverse direction or tapers in the transverse direction, or the second end face does not increase in extension in the transverse direction or ends with a heel, the extension of which in the transverse direction is at most 1.2 times the extension of the recessing section in the transverse direction;wherein the recessing section is provided with an internal thread that is oriented with a thread axis in the direction of longitudinal extension and is accessible from the first end face;wherein the internal thread is formed in a threaded part inside a mounting space that is formed inside the recessing section, and wherein said threaded part is arranged moveable relative to the mounting space; andan elastic cushioning element that is disposed between the threaded part and a wall of the mounting space that delimits the mounting space in the direction of longitudinal extension. 7. The mounting insert according to claim 6, further comprising a vent hole defined in a base of the mounting space. 8. The mounting insert according to claim 6, further comprising at least one radially offset through hole(s) that is provided in the collar. 9. The mounting insert according to claim 6 wherein the recessing section takes the form of a circular cylinder, and wherein the collar is circular. 10. The mounting insert according to claim 6, wherein the recessing section has a greater length in a first transverse direction that extends transverse to the direction of the longitudinal extension than in a second transverse direction that extends transverse to the direction of the longitudinal extension and transverse to the first transverse direction. 11. The mounting insert according to claim 8, comprising multiple radially offset through holes that are provided in the collar. 12. The mounting insert defined in claim 6, wherein the collar is perpendicular to the recessing section. 13. A mounting insert for installation in a lightweight sandwich panel, wherein the mounting insert comprises: a recessing section for the recessed insertion into a recess defined in the lightweight sandwich panel; wherein the recessing section is longitudinally extended in a first direction; wherein a mounting space is formed in the recessing section, anda threaded part is arranged moveably in the mounting space transverse to the direction of the longitudinal extension; wherein said threaded part is provided with an internal thread that is oriented with a thread axis in the direction of longitudinal extension of the mounting insert and is accessible from a first end face of the recessed section; andan elastic cushioning element is disposed between the threaded part and a wall of the mounting space that bounds the mounting space in the direction of longitudinal extension.
