And; The ring muscle is that a bar bends the microscler closed circular that is in said, and technologies such as contact place use welding are fixedly connected, and the space cooperates the diameter of vertical muscle as far as possible in the closed circular; When construction, just can be fixed in outer shroud muscle and the interior ring muscle closed ring indulging muscle; Retrain the position of indulging muscle firmly with outer shroud muscle and interior ring muscle, between outer shroud muscle and interior ring muscle and vertical muscle bigger contact surface is arranged, strengthened the steadiness of whole bar structure.

Further: said housing muscle is square, is provided with interior muscle in the housing muscle, and said interior muscle two ends are provided with bar and enclose the circular arc that is, and the circular arc at said interior muscle two ends is connected on the housing muscle.

Its characteristics are: can realize the technique effect same with first scheme.

Further: muscle in muscle comprises crisscross horizontal interior muscle and indulges in said, horizontal interior muscle is fixedly connected with the vertical interior staggered position of muscle, is provided with contact between the summit of interior muscle two ends circular arc and outer shroud muscle, and the junction of crossing interior muscle is provided with contact.

Its characteristics are: can adapt to more complicated construction needs.

Further: said contact is a solder joint, and said solder joint is not limited to spot welding, also comprises welding manners such as line weldering, face weldering.

Its characteristics are: the mode of welding more is prone to implement; Only establishing solder joint at the mid point of said segmental arc can reduce the welding job amount simultaneously.

Further: to be that two bars are parallel paste and connect together the muscle middle-end mutually in said.

Further: the stage casing of muscle is that two bars reverse the Double-spiral that is in said.

Its characteristics are: the said mechanical strength that has increased reinforcing bar self of reversing.Also increase the surface area of reinforcing bar, and then increased reinforcing bar and concrete bond stress, mechanical snap power, better to the binding effect of concrete lateral deformation.And in some cases, use thinner reinforcing bar to bend and reverse then just can reach characteristic, thereby better promote the application space of material than bar reinforcement.

Further: muscle is two long limits and two microscler closed circulars that semi arch surrounds in said.

Its characteristics are: through above structure; Intersection between outer shroud muscle and interior ring muscle has formed a series of fixing hole; Vertical muscle can be constrained in the said fixing hole; Vertical like this muscle is fixed by the outer shroud muscle more than two and two, the constraint of interior ring muscle simultaneously, has increased the face of being in contact with one another, and has further increased stability of structure.
