<p>A weldless connection system for U-beam particle separators is provided in which one end of each U-beam (10) is provided with sides (15, 35) and a back (25) that are separated from each other forming tabs (Fig. 2). The tabs may be bent, or folded, about 90° inward toward the channel formed by the U-beam. The back tab (25a) may be twice as long as the side tabs, and the extra half length of the tab can be folded about 180° back at the back of the U-beam in a double thickness. Each tab has a hole (20, 30, 40) therethrough. The double-length back tab (25a) has two holes; one hole is provided through each half (Fig. 2). When the tabs are bent inward, the holes align. A bolt and washer (70) placed through the aligned holes may be used to secure the tabs, and thus the U-beam, to a furnace roof structure (200). An alternate embodiment of the invention is provided in which only the sides of the U-beam form tabs which extend past the bottom of the U-beam.</p> |
