Specification of Letters Patent. I PatentQdAug. 6, 1912.
Application filed June 18, 1909. Serial'No. 502.973.
To all whom it may concern:
Be it known thatl, CLAUDE A. P. TURNER, of Minneapolis, in the county of Hennepin and in the State of Minnesota, have invented a certain new and useful Improvement in Concrete-Arch Reinforcements, and
do hereby declare that the following is a full, clear, and exact description thereof.
,My-invention relates to the reinforcement of concrete. arches of the Monier type of double reinforcement where the lines or planes of the two sets of reinforcing rods or bars are so separated as to make the matter ofholding them in position while the concrete is being poured, a diiiicult one, and my object is .eficiently and economically to do this work.
To this end my invention consists in the arch reinforcement substantially as hereinafter specified and claimed.
In the drawings, Figure 1 is a side elevation of a fragment of an arch embodying my invention;.Fig. 2 a topplan view of a.
portion thereof; rig. 3 a detail-view in perspective'ot a portion thereof; Fig. 4 a detail view in top plan showing the connection between the angle bar and the reinforcing rods or bars; Fig. 5 a detail View inside elevation of the same.
Referring to thedrawings, and 11, respectively, designate two lines or groups of longitudinally and transversely extending bars arranged, respectively, near the intrados and the extrados of the arch. Situated at the angles oi the intersection of the longitudinal and transverse bars of the lines or groups and perpendicular thereto, are radially extending angle bars 12, to which the bars are suitably attached, and which thereby tie or hold the two groups together as a rigid framework, resting on the falsework on which the concrete is placed. -One flange of an angle bar 12 has secured to it the longitudinally extending bars 10 and the other flange has attached to it the transversely extending bars 11. The said flanges are punched or otherwise provided with holes for staples or U-bolts 14 by which the bars 10 and 11 are fastened thereto. Pref erably the angle bars are placed in-staggered order.
.What I claim is i 1. In a reinforced concrete construction, the combination of separatedgr'oups of reintorcing bars the bars of each group ex tending in intersecting lines,- the .two groups being situated to extend through the mass or body of concrete toward the opposite sides thereof, angle bars running'from the angles of intersection of the bars'of one group across to the second group at the corresponding angles formed by the bars of said second group, the bars of a group in one direction being against one web of said angle bars, and the bars pfa group in the other direction being at the other web of said angle bars, and means securely attaching the groups of reinforcing bars to the webs of said angle bars.
2. In a reinforced concrete construction, the combination of separated groups of reinforcing bars the barsof each group extending in intersecting lines, the two groups being situated to extend through the mass m or body of concrete toward the opposite sides thereof, angle bars running from the angles of intersection of-the bars of one groupacross to the second group at the corresponding angles formed by the bars of said second group, the bars of a group in one direction being against one web of said angle bars, and the barsof a group in the other direction being at the other web of said angle bars,- and staples securing said groups of bars to the webs of the angle bars.
. In testimony that I claim the: foregoing I have hereunto set my hand.
