A method for making a composite structural member. The composite structural member has a flange having a base wall and two side walls extending from the base wall, the base wall and side walls forming a pocket to receive a portion of a web. Each side wall of the flange is doubled with an inner wall panel and an outer wall panel joined along a fold line spaced from, and parallel to, the base wall. Fasteners are formed from each side wall adjacent the fold line, each fastener having inner and outer wall panel sections joined by a section of the fold line and extending transversely from its side wall toward the other side wall. The flange is used with the web, a portion of the web mounted in the pocket with the side walls of the flange adjacent the sides of the web and the fasteners pressed into the sides of the web to secure the flange to the web. The method comprises the steps of: mounting the web within the pocket of the flange to form an elongated assembled unit; moving the unit longitudinally; forming the fasteners in the side walls while the side walls diverge from the web and the unit moves; and then moving the side walls against the web to press the fasteners into the web while the unit moves to secure the flange to the web.

대표청구항 ▼

I claim: 1. A method of making a composite structural member comprising: providing an elongated flange having a pocket, the pocket formed by two side walls extending from a base wall; the flange having no fasteners formed therein: providing an elongated web having opposed narrow edges; mounting a portion of the web within the pocket of the flange with one edge of the web abutting the base wall of the flange to form an elongated, assembled unit; feeding the assembled unit in a longitudinal direction the unit passing a first station while being fed longitudinally and forming fasteners from the side walls of the flange while the side walls are diverging from the web at the first station, the fasteners integral with the side walls, and the unit immediately passing a second station after leaving the first station while being fed longitudinally, moving the side walls against the web at the second station to press the integral, formed, fasteners into the web to securely join the flange to the web. 2. A method as claimed in claim 1 wherein the assembled unit is stopped at the first station to form the fasteners while being fed in the longitudinal direction. 3. A method as claimed in claim 2 wherein each side wall of the flange has inner and outer wall panels joined by a fold line spaced from the base wall. 4. A method as claimed in claim 3 wherein the fasteners are formed adjacent the fold line in each side wall, each fastener including a portion of the fold line. 5. A method as claimed in claim 4 including the step of spreading the side walls away from the web during feeding of the unit before the fasteners are formed. 6. A method as claimed in claim 5 wherein each fastener is formed by cutting the side wall along a line that angles to, and intersects, the fold line, the cut line and fold line defining a side wall portion between them and then bending the side wall portion toward the other side wall. 7. A method as claimed in claim 4 wherein the fasteners are formed by punching out the fasteners from the side walls. 8. A method as claimed in claim 4 wherein each fastener is formed by cutting the side wall along a line that angles to, and intersects, the fold line, the cut line and fold line defining a side wall portion between them and then bending the side wall portion toward the other side wall. 9. A method as claimed in claim 2 including the step of spreading the side walls away from the web during feeding of the unit before the fasteners are formed. 10. A method as claimed in claim 2 wherein the fasteners are formed by punching out the fasteners from the side walls. 11. A method as claimed in claim 2 including the step of spreading the side walls away from the web during feeding of the unit before the fasteners are formed. 12. A method as claimed in claim 1 wherein the assembled unit is fed continuously longitudinally to the first and second stations.
