Describe the reinforcing bar 100 according to the utility model embodiment in detail referring to Fig. 1-Fig. 3, this reinforcing bar 100 can be used as constructional materials and is applied in reinforced concrete structure.
Reinforcing bar 100 according to the utility model embodiment comprises reinforcing bar body, and reinforcing bar body comprises at least one section of straightway 2 and at least one section of raised section 1, and raised section 1 relative rectilinear section 2 is protruded and arranged, and in other words, raised section 1 and straightway 2 are non-colinear structure.This at least one section such as multistage straightway 2 can be arranged by conllinear, as depicted in figs. 1 and 2, but is not limited thereto.
Alternatively, as shown in Figure 1, a raised section 1 can be formed with between two straightways 2.Or alternatively, multiple raised section 1 can be formed with between two straightways 2.Certainly, raised section 1 and straightway 2 can also be interlaced arrangement, and namely reinforcing bar body forms according to straightway 2 arrangement of 1, one, a raised section.It should be noted that, the description here about the arrangement mode of raised section 1 and straightway 2 is only schematic, can not be interpreted as it is to one restriction of the present utility model.
According to the reinforcing bar body of the utility model embodiment owing at least having one section of raised section 1, namely protrude the bulge-structure of straightway 2, therefore also can be referred to as " wave inception reinforcing bar " according to the reinforcing bar 100 of the utility model embodiment.
The raised section 1 of being somebody's turn to do " wave inception reinforcing bar " can be straightened when under tension, therefore " wave inception reinforcing bar " is somebody's turn to do when having with traditional line steel bar same intensity, also there is extending and deforming capacity more better than traditional line steel bar, can also be formed " the wave inception reinforcing bar " with different distortion ability by the size, structure etc. controlling " wave inception " (i.e. raised section 1).
Compared to traditional line steel bar, " the wave inception reinforcing bar " with " wave inception " structure according to the utility model embodiment has better deformability.
For the shape of raised section 1, it is directly connected to the deformability of reinforcing bar 100, and in embodiments more of the present utility model, as shown in Figure 1, raised section 1 can be formed as general triangular.In the embodiment of fig. 2, raised section 1 can be also circular arc, as semicircular arc.Certainly, raised section 1 can also be parabola shaped or other shape.
Particularly, the embodiment of composition graphs 1, raised section 1 comprises the first skew lines section 11 and the second skew lines section 12, the first end 111 of the first skew lines section 11 is connected with the first end 121 of the second skew lines section 12, first skew lines section 11 and the second skew lines section 12 can form an angle, such as this angle can be 30 °-150 °, but is not limited thereto.Second end 112 of the first skew lines section 11 is connected with straight line section 2 (straightway 2 in left side), second end 122 of the second skew lines section 12 is connected with another straightway 2 (straightway 2 on right side), that is, as shown in Figure 1, at each side connection one straightway 2 of this triangular hill section 1.
Further, as shown in Figure 1, can be connected by First Transition section 21 between first skew lines section 11 and the second skew lines section 12, second end 112 of the first skew lines section 11 is connected by the second changeover portion 22 with described straight line section 2 (straightway 2 in left side), and the second end 122 of the second skew lines section 12 is connected by the 3rd changeover portion 23 with described another article of straightway 2 (straightway 2 on right side).Thus, seamlessly transit between raised section 1 and straightway 2, effectively can improve the deformability of reinforcing bar 100.
As preferred embodiment, First Transition section 21 respectively with the first skew lines section 11 and the second skew lines section 12 tangent, second changeover portion 22 respectively with the second end 112 of the first skew lines section 11 and described straight line section 2 (straightway 2 in left side) tangent, the 3rd changeover portion 23 respectively with the second end 122 of the second straightway 2 and described another article of straightway (straightway 2 on right side) 2 tangent.Thus, make transition between raised section 1 and straightway 2 obtain more level and smooth, be more conducive to the deformability improving reinforcing bar 100.
In this embodiment, as shown in Figure 1, reinforcing bar body can be structure as a whole and by processing traditional line steel bar.Such as, reinforcing bar body is by carrying out cold working formation to traditional line steel bar.Thus, technique is simple, convenient formation, can effectively reduce costs.
In other embodiments of the present utility model, as shown in Figure 2, the two ends of raised section 1 are connected to end straightway 13, and one end that the distance raised section 1 of end straightway 13 is far away and straight line section 2 are fixed by fixed connecting piece (as metal sleeve 3).Thus raised section 1 can be formed " wave inception bar dowel " with the end straightway 13 at these two ends, raised section 1, the two ends of being somebody's turn to do " wave inception bar dowel " respectively can connect a linear pattern reinforcing bar and straightway 2, thus form " the wave inception reinforcing bar " according to the utility model embodiment.
In this embodiment, as shown in Figure 2, fixed connecting piece can be metal sleeve 3, thus convenient fixing, firm.But the utility model is not limited to this, the straightway reinforcing bar at such as " wave inception bar dowel " and two ends also can by weld or alternate manner is fixed.
Shown in composition graphs 3, shown in Fig. 3 according to the utility model embodiment " wave inception reinforcing bar " deformation when being subject to larger external force, from the schematic diagram of Fig. 3, we can find out with cleaning, the distortion of " wave inception reinforcing bar " takes the lead in occurring in " wave inception " place (i.e. raised section 1 part), along with the change of external force is large, " wave inception " part is by stretching gradually, substantially the variant of generic linear steel bar is there is after stretching again in this part, therefore traditional line steel bar is compared, according to the process that " the wave inception reinforcing bar " of the utility model embodiment is straightened due to many " wave inception " parts, therefore there is deformability more better than generic linear steel bar.
In the description of this manual, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, to the schematic representation of above-mentioned term not must for be identical embodiment or example.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.In addition, the different embodiment described in this manual or example can carry out engaging and combining by those skilled in the art.
