Adhesive-distributing device and method for adhesively bonding hollow profiles using the adhesive-distributing device
An adhesive-distributing device for use in repairing or reconditioning a hollow profile includes an adapter body, in which is arranged at least one channel system made up of at least two channels connected to one another. At least one channel is connected to an injection opening for injecting adhesive into the channel system. Each channel is designed with at least one exit opening.
1. A method for repairing a hollow profile with a repair profile via an adhesive-distributing device, the method comprising the acts of:
a. providing the adhesive-distributing device with an outer contour that corresponds to an inner contour of the hollow profile to be repaired and the repair profile, which outer contour has a smaller cross-section than the inner contour;
b. introducing one or a plurality of wall-side openings into the hollow profile and/or repair profile corresponding to a number of existing injection openings of the adhesive-distributing device;
c. introducing the adhesive-distributing device with one each connecting section into the hollow profile as well as into the repair profile such that the wall-side openings are each in alignment with corresponding injection openings, forming a circumferential bonding gap;
d. injecting an adhesive via the injection openings into channel systems arranged in an adapter body of the adhesive-distributing device until the bonding gap is completely filled with adhesive, wherein each channel system has a first vertical channel, a second vertical channel, a first horizontal channel, and a second horizontal channel, wherein the first vertical channel, the second vertical channel, the first horizontal channel, and the second horizontal channel meet at a joint junction, wherein at least one of the first vertical channel, the second vertical channel, the first horizontal channel, and the second horizontal channel is connected to a respective injection opening, and wherein each of the first vertical channel, the second vertical channel, the first horizontal channel, and the second horizontal channel has a respective exit opening in a respective lateral surface of the adapter body.
2. The method according to claim 1 , wherein the act (c) of introducing the adhesive-distributing device further comprises the acts of:
(i) in a first act, introducing the adhesive-distributing device completely into one of the hollow profile or the repair profile;
(ii) in a second act, positioning the hollow profile and the repair profile with face ends flush to one another; and
(iii) in a third act, displacing the adhesive-distributing device into the other of the hollow profile or repair profile such that the openings are in alignment with respective corresponding injection openings and form a circumferential bonding gap.
3. The method according to claim 1 , wherein the openings have a larger opening cross-section than the corresponding injection openings so that, directly after filling the bonding gap in act (d), adhesive escapes from the openings.
4. The method according to claim 1 , wherein the first and the second horizontal channels are not disposed centrally within the adapter body and are disposed within an upper third of the adapter body.
