A resilient clip in three integrally joined sections: a central or web section centered on a z-axis, and two extensions from the web extending along x- and y-axes. Each section or portion may be described as a split sleeve and has a generally cylindrical opening therethrough, respectively centered on the same three axes. These openings are contoured and disposed to snugly receive a reinforcing bar or rod and a pair of corner legs of a generally rectangular stirrup, a piece of heavy wire bent into a rectangular shape and receiving reinforcing bars at its four corners, holding them in such positions to maintain the planned spacing between rebars. Each of the central openings through the three parts is joined to the outside by a lateral slit defined by a pair of lips that are forced apart by pushing the clip onto the steel member. The extensions of the clip may each have a second cylindrical opening which is parallel to the first mentioned and closely adjacent thereto, to accommodate parallel legs of the stirrup when the two ends thereof overlap. The pair of extensions may either face in opposite directions, or they may face in the same direction, whereby both extensions may be simultaneously mounted on the legs of a stirrup corner by a single pushing action. The clip may also be used to secure together any three mutually perpendicular rods or bars.
In a concrete reinforcing system, a clip for securing together a reinforcing bar and the pair of legs forming one corner of a wire stirrup, such clip being of resilient material and having a central web portion in the general shape of a split sleeve adapted to receive said reinforcing bar, said web portion having an opening extending therethrough along a first axis defining a first line of action, and two split sleeve extensions integrally secured to the web and extending therefrom with through openings extending along second and third axes defining second and third lines of action which are perpendicular to each other said second and third lines of action being coplanar whereby the legs of the stirrup received therein will also be coplanar, each split sleeve extension being conformed and disposed to encircle and receive one of the legs of the stirrup.
In a concrete reinforcing system, a clip for securing together a reinforcing bar and the pair of legs typically meeting at the origin of a three dimensional Cartesian coordinate system having x, y, and z axes, such clip being of resilient material and having a central web portion with an opening therethrough adapted to receive the reinforcing bar disposed along the z axis and also having two extensions integrally secured to the web with each extension having an opening therethrough adapted to encircle and receive one of the legs of the stirrup, said openings of the extensions being centered on the x and y axes, respectively, and lying in a common plane generally normal to the z axis, each of the openings of the central web portion and extensions having a lateral passage joining the opening to the exterior of the clip, each such lateral passage being defined by a pair of lips which are spread apart in mounting the clip.
A clip for securing together three mutually perpendicular rod or bar members, such clip being of resilient material and having a central web portion in the general shape of a split sleeve having an opening therethrough extending along a first axis adapted to receive one of said rods or bars and two split sleeve extensions integrally secured to the web and extending therefrom with openings therethrough extending along second and third axes which are normal to each other and lie in a common plane which is which normal to the first axis along which the opening through the web member extends, each split sleeve extension being conformed and disposed to encircle one of the other two bars or rods.
