Abstract

A concrete reinforcement is formed from at least one pair of Lsection reinforcing elements each comprising a plurality of transversely extending angle members interconnected by longitudinal bars, at least one of which is disposed at the bend of the transverse elements. The legs of the L interdigitate and a clip connects the longitudinal bar with a leg of a transverse bar to secure the two reinforcing sections in basket-shaped or Usection relation.

Claims

1. A concrete reinforcement for beams, columns and the like, comprising a pair of L-section reinforcement elements each comprising a plurality of longitudinally spaced L-shaped transverse bars lying in respective parallel planes, a first longitudinal bar secured to said transverse bars at the bends thereof and extending perpendicular to said planes, and a second longitudinal bar secured to codirectionally extending legs of the transverse bars and spaced from said first longitudinal bar, said elements having said codirectionally extending legs interdigitating and lying in a common plane parallel to said longitudinal bars with said second longitudinal bars of the two elements laterally abutting, and clips interconnecting the first longitudinal bar of one element and a leg of the other element.

2. The reinforcement defined in claim 1 wherein the second longitudinal bar of each element lies along the interior of the L-section formed by the element and each element further comprises another longitudinal bar interconnecting the other legs of said transverse bars and parallel to said first and second longitudinal bars of each element.

3. The reinforcement defined in claim 2 wherein said clips each have a pair of bores extending at right angles to one another and are formed with slots communicating with said bores to enable said legs and said first longitudinal bars to be thrust into the respective bores.

4. The reinforcement defined in claim 2 wherein said clips are formed with bores and slots enabling said clips to receive said first longitudinal bars and are further provided with flanges forming stops for said legs.

5. The reinforcement defined in claim 2, further comprising another L-section element having L-shaped transverse bars and longitudinal bars with legs interdigitated with legs of one of the first-mentioned pair of elements whereby said reinforcement has a box-like cross-section.

6. The reinforcement defined in claim 2 wherein said second and another longitudinal bars are spaced substantially mid-way along the length of the respective legs.

7. The reinforcement defined in claim 2 wherein said longitudinal bars are welded to said transverse bars.

8. A concrete reinforcement for beams, columns and the like, comprising a pair of L-section reinforcement elements each comprising a plurality of longitudinally spaced L-shaped transverse bars lying in respective parallel planes, and a longitudinal bar secured to codirectionally extending legs of the transverse bars at an intermediate location thereon, said elements having said codirectionally extending legs interdigitating and lying in a common plane parallel to said longitudinal bars with said second longitudinal bars of the two elements laterally abutting;

another longitudinal bar lying along the bends of the transverse bars of one element and at the ends of the interdigitated legs of the other element; and

clips interconnecting said other longitudinal bar to legs of said elements.

9. The reinforcement defined in claim 8 wherein each element further comprises another longitudinal bar interconnecting the other legs of said transverse bars and parallel to the previously mentioned longitudinal bars.

10. The reinforcement defined in claim 8 wherein said clips each have a pair of bores extending at right angles to one another and are formed with slots communicating with said bores to enable said legs and said first longitudinal bar to be thrust into the respective bores.
