I claim the ornamental design for an I-joist, as shown and described.
A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.
FIG. 1 is a perspective view of a first embodiment of an I-joist showing my new design; and,
FIG. 2 is a perspective view of a second embodiment of the I-joist showing my new design.
The I-joist is shown with a symbolic break in its length. The appearance of any portion of the I-joist between the break lines forms no part of the claimed design.
