Abstract
A method is provided for connecting hollow profiles (1-4) in a joint (10) to produce a load-bearing structure (5). The method includes placing ends of hollow profiles (1-4) in a mold and pressing the ends together with at least one semi-finished product to connect the ends of the hollow profiles to the semi-finished product.
Claims8
A method for producing a load-bearing structure, comprising:
- providing a semi-finished composite body having a plurality of plug-in regions each of which has an open end and one open side, the semi-finished composite body being formed from a first fiber/plastic composite material;
- placing the semi-finished composite body in a mold;
- placing ends of profiles in the open sides of the plug-in regions of the semi-finished composite body, each of the profiles having a hollow portion formed from a second fiber/plastic composite material and a rigid foam core filling and reinforcing all of the respective hollow portion;
- and
- pressing the plug-in regions of the semi-finished composite body together with the ends of the profiles in the plug-in regions of the composite body in the mold to connect a plurality of sides of the ends of the profiles firmly to the semi-finished composite body;
- and
- heating the regions of the semi-finished composite body that have been pressed to the ends of the profiles sufficiently to cross link plastic of the first fiber/plastic composite material to plastic of the second fiber/plastic composite material to form the load-bearing structure.
