Abstract

A method for fastening an in particular tub-shaped floor panel to an in particular frame-like vehicle structure is provided. The method includes applying an adhesive to a contact surface of the floor panel and/or of the vehicle structure, and joining the floor panel and the vehicle structure. The method includes expanding and/or activating the adhesive by heating the joint vehicle structure-floor panel composite.

Claims (24)

1. A method for fastening a floor panel to a vehicle structure comprising:

applying an adhesive to a contact surface of at least one of a tub-shaped floor panel and a frame-like vehicle structure;

joining the floor panel and the frame-like vehicle structure;

at least one of expanding and activating the adhesive through heating the joined vehicle structure and floor panel, wherein

the floor panel further comprises an elastically deformable fixing means configured to connect the floor pane to the frame-like vehicle structure after passing completely through the frame-like vehicle structure.

2. The method according to claim 1 , further comprising:

delivering the floor panel with the adhesive applied to an assembly line in which it is joined to the frame-like vehicle structure; and

heating the joined vehicle structure and floor panel.

3. The method according to claim 2 , further comprising:

heating the joined vehicle structure and floor panel to at least one of expand and activate the adhesive in a drying oven of a painting facility.

4. The method according to claim 3 , wherein the floor panel and the frame-like vehicle structure are one of positively and frictionally connected prior to the heating.

5. The method according to claim 1 , wherein the adhesive is applied in a depression.

6. The method according to claim 1 , wherein the floor panel is produced from plastic and the frame-like vehicle structure from metal.

7. The method according to claim 1 , wherein the adhesive is of a self-adhesive type, and further comprises a foam adhesive.

8. The method according to claim 3 , wherein the adhesive hardens after the heating.

9. The method according to claim 1 , wherein the adhesive seals the floor panel against the frame-like vehicle structure.

10. A vehicle floor assembly, comprising:

a vehicle structure; and

a floor panel that is fastened to the vehicle structure by an adhesive applied to a contact surface of at least one of the floor panel and the vehicle structure,

wherein the adhesive is heated to activate the adhesive and fasten the vehicle structure and floor panel; and

an elastically deformable fixing means formed on the floor panel connecting the floor panel and the vehicle structure after passing completely through the vehicle structure.

11. The vehicle floor assembly according to claim 10 , wherein the elastically deformable fixing means is configured to positively connect the other floor panel and the vehicle structure.

12. The vehicle floor assembly according to claim 11 , wherein the other of the floor panel and the vehicle structure further comprises a flange that is braced between the adhesive contact surface and the elastically deformable fixing means.

13. The vehicle floor assembly according to claim 10 , wherein at least one of the floor panel and the vehicle structure further comprises a depression in which the adhesive is arranged.
