A clip is disclosed which can be used to fabricate the lattice structure of reinforcing rods of the type used in the construction of steel rod reinforced concrete slabs. An apparatus to fasten those clips in position is also disclosed The preferred clip (1) has a substantially rectangular body (2). A recess (3) extends from a first face (4) of the body (2) towards an opposite face (5). The recess (3) terminates in an arcuate portion (6). The inner edges (7a, b) of the recess (3) are convergent towards the arcuate portion (6). The apparatus has an aperture (13) in a base plate (12). Stops (18a, b, c) on the plate (12) suitably position the apparatus whereupon a shearing plate (32) can shear a clip (1) from a stack of such clips to pass through the aperture (13) wherein the arcuate portion (6) of the clip (1) engages the upper rod (16). A pair of pivoting J-shaped arms (21a, b) are then actuated which bend the lower portions of the clip (1) around the lower rod (17) securing the two rods (16, 17) together.
A clip for use in the fastening together of two crossing substantially elongate upper and tower members, said clip including a substantially planar body with a recess extending from a first face to near a second face substantially opposite said first face to form a first arm and a second arm, said recess terminating with a shaped portion of a configuration substantially complementary to the exterior surface of said upper member, said clip being adapted such that, when said clip is in a fastening position, said recess can engage said upper member and said first arm and said second am can each be conformed to a configuration substantially identical to the exterior surface of said lower member sufficient to engage with said lower member to fasten said upper member and said lower member together.
A lattice-type arrangement comprising a series of crossing lower and upper members wherein each intersection of said upper and lower member has been fastened with a clip, said clip including:
