    • 603,084. Casting concrete &c. structures in situ. McKEAN, J. L., and RICHARDS, G. Nov. 17, 1944, No. 22842. [Class 20(ii)] Shuttering for casting concrete and reinforced concrete structures, comprises panels, uprights and horizontal members made by'cold rolling strip steel, the panels being of channel section with inturned flange edges and being supported in shuttering position by clamps engaging the inturned flange edges and passing through slots in spaced uprights, means being provided for tensioning the clamps at any desired location along the slots of the uprights. The uprights may consist of four angle irons 6, Fig. 11, assembled to form a member of rectangular section with open sides by channel members 7 secured to the angle irons by welded cleats 8, the shuttering panels 1, which have flanges 2 with beaded edges 3, being secured to the uprights by double or single metal loops 9, 9 having hooked ends 13 engaging within the beaded edges of the panels and tightened by tapered rods 12 driven through the loop projection through the opposite face of the upright. The panels are stiffened by transverse welded angle bars 4. Internal corners are formed by box members 13 , Fig. 12, with out-turned flanges 15 secured to angle strips 14, the panels bearing on the flanges 15. External corners are formed by strips 17, Fig. 13, with bevelled edges 17 and bolts 19 which project between meeting panels, the strip being secured by a yoke 18 and nut 20. The framing for the panel shuttering is built of uprights and similarhorizontal members bolted together and braced. Strips 21, Fig: 14, and chamfer boards 24 to form recesses &c. on the face of the structure may be fitted, the strip 21 being of open box section and being secured to adjacent panels by a plate bearing on the inside of the flanges of the open side and having a lug 23 projecting between the panel flanges and clamped by a tapered cottar 12 . The panels may be in two widths e.g. 9 in. and 12 in..and filler strips of wood may be used to complete shuttering of odd dimensions.

A unit for building girders, arches &c. comprises a chord 11 and a shorter chord 12 connected together by struts and adapted to be connected to other units in line by fishplates bolted to holes 30 in the ends of the chords. The chords are connected together by two main struts 18, 19 each connected at its middle to the middle of the chords by diagonal struts 20-23. The units may be connected side by side by means of brackets 42 or holes in the chords. The chords comprise two angle irons welded together to form a U-section with the mouths directed away from the unit and closed in places by plates 36-41. An arch is constructed by connecting units end to end with fishplates of suitable lengths and the curve may be adjusted by eccentrics on the fishplate connecting bolts. The fishplates for the chord 11 each has a third hole for a shear bolt engaging a hole 35 in the chord 11. Specification 865,185 is referred to.

Classes 20(1) and 20(2) [Also in Group XXV] Units for making bars for building structures comprises a channel Fig. 4, the web 1 of which extends beyond the flanges 12 to form lugs 16, 20 reinforced by plates 15, 22 and offset from one another so that the inner face of the lug 16 is in the same plane as the outer face of the lug 20. The edges of the flanges have inturned lips 13. These channels are welded back to back or front to front by the flanges 13 to form I or box section bars respectively. The bars are used to build up triangulated structures having pairs of ears 16, 20 Fig. 11 at the ends spaced at different distances so that the ears of one bar fit between the ears of another. The bars are shown built up to form girders having vertical and diagonal braces. Cross spacing for connecting the girders comprise an angle 114 Fig. 10 passed through a slot in another angle 115 and connected by a bolt 117. Fig. 14 (not shown) shows a column. A bridge Fig. 13 comprises two pairs of double trusses 112 connected by diagonal braces 114, 214 and having the ends mounted by plates 124 on a timber bearer 123 and having a wooden floor 125.
