Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
Secondly; the utility model is described in detail in conjunction with schematic diagram; when describing the utility model embodiment in detail; for ease of explanation; the sectional drawing of indication device part structure can be disobeyed general ratio and be made partial enlargement; and described schematic diagram is example, it should not limit the scope of the utility model protection at this.In addition, the three-dimensional space of length, width and height should be comprised in actual fabrication.
Embodiment 1:
As depicted in figs. 1 and 2, the utility model comprises reinforcing bar body 1, and the two ends of described reinforcing bar body 1 are respectively overlapped 3 anchors 2, and described anchor 2 is metal hollow annulus.
Described reinforcing bar body 1 is plain steel-bar or spiral ribbed reinforced bar or indented bar or steel strand, and described anchor 2 is matched in clearance or interference fit with described reinforcing bar body 1.During matched in clearance, after described anchor 2 cover is installed to permanent position, clamp described anchor 2 by tonger, be fixed, or by welding or the mode such as bonding also passable.
Embodiment 2:
As shown in Figure 3 and Figure 4, the utility model comprises reinforcing bar body 1, and on one end of described reinforcing bar body 1, cover has 3 anchors 2, and described anchor 2 is hollow square body.
Described reinforcing bar body 1 is prestressed spiral rib steel muscle, the inwall of described anchor 2 is provided with the screw thread adapted with the spiral of described reinforcing bar body 1, during installation, after described anchor 2 socket is rotated to permanent position, described anchor 2 is clamped by tonger, be fixed, or by welding or the mode such as bonding also passable.
Embodiment 3:
As shown in Figure 5 and Figure 6, the utility model comprises reinforcing bar body 1, and the two ends of described reinforcing bar body 1 are respectively distributed with 1 anchor 2, described anchor 2 for cross section be hexagonal metal hollow cylinder.
Described reinforcing bar body 1 is indented bar.Described anchor 2 and described reinforcing bar body 1 be matched in clearance, after described anchor 2 cover is installed to permanent position, clamp described anchor 2, be fixed by tonger, or also passable by the mode such as welding or bonding.
