1,237,840. Spiked plates. AUTOMATED BUILDING COMPONENTS Inc. 12 June, 1969 [27 Aug., 1968], No. 29867/69. Heading F2H. A spiked plate comprises sheet metal member 16 having teeth 18 extending from two opposite side edges of the member, the teeth having, adjacent their roots, shoulder portions 22 for penetrating a member with which the spiked plate is to be used. The teeth 18 may be of equal length or of different lengths to adjacent teeth (Fig. 8, not shown) or to those on the opposite side edge of the member 16 (Fig. 10, not shown). The teeth may be dished across their width and axially aligned or offset relative to those on the opposite side edge of the member 16. The teeth 18 may be longitudinally straight or curved and the member 16 may be bent so that the spiked plate is of serpentine nature (14) (Fig. 1, not shown) or part circular in cross-section (Figs. 11, 12, not shown). The spiked plate may be used to connect two wooden members in face-to-face abutment so as to form a laminated beam structure. |
