In the present embodiment, the first aligning partses 110 and the second aligning partses 120 are half round buss respectively, by first
After first connector 141 and the 3rd connector 151 are linked together by securing member 161, and incited somebody to action by the second securing member 162
After second connector 142 and the 4th connector 152 link together, the first aligning partses 110 and the second aligning partses 120 shape
Become the cylindrical drum of hollow and between the first aligning partses 110 and the second aligning partses 120, form centring hole 170.First fastening
Part 161 and the second securing member 162 achieve being detachably connected of the first aligning partses 110 and the second aligning partses 120, thus steel
The working space scope of muscle centralising device 100 is wider.Additionally, the size of reinforcing bar centralising device 100 can be according to will connect
The size of reinforcing bar and other require to be selected, thus in narrow and small working space can smooth operation, convenience and high-efficiency.
Refer to Fig. 1 and Fig. 5 it is shown that the operation principle of reinforcing bar centralising device 100, steel locked by reinforcing bar centralising device 100
The locking plate of muscle connector thus forcing reinforcing bar that elastic deformation occurs and non-plastic deformation, so moment is less, save manpower and
Safety, will not occur centering instrument to pull down the position before rear reinforcing bar returns centering.
First, put together in one end of one end of the first reinforcing bar 191 to be connected and the second reinforcing bar 192, first
The outside of reinforcing bar 191 and the second reinforcing bar 192 wraps the first locking plate 171, the second locking plate 172, the 3rd locking plate 173 and the 4th respectively

Bolt 163.Before nut 164 not being tightened, have between the first aligning partses 110 and the second aligning partses 120 certain between
Gap, with tightening of nut 164, the gap between the first aligning partses 110 and the second aligning partses 120 reduces to lock lock
Piece, realizes the first reinforcing bar 191 and the centering of the second reinforcing bar 192.
First aligning partses 110 and the second aligning partses 120 are respectively by the first locking plate 171 and the second locking plate 172 applying power
And compressed, and the 3rd locking plate 173 and the 4th locking plate 174 are applied by the first aligning partses 110 and the second aligning partses 120
Afterburning and compressed, the first locking plate 171, the second locking plate 172, the 3rd locking plate 173 and the 4th locking plate 174 reduce first respectively
Reinforcing bar 191 and the axial deviation of the second reinforcing bar 192, that is, the centrage of the centrage of the first reinforcing bar 191 and the second reinforcing bar 192 is one
On bar straight line, after nut 164 is finally tightened, between the first reinforcing bar 191 and the second reinforcing bar 192, there is no axial deviation.Work as steel
First sleeve 181 of the both sides of muscle connector can be inserted in the first locking plate 171 and the second locking plate 172 and second sleeve 182 can
During being inserted in the 3rd locking plate 173 and four locking plates 174, reinforcing bar centering end-of-job, thus realize the first reinforcing bar 191 and the second steel
The centering of muscle 192.
Additionally, reinforcing bar centering is carried out with the installation of sleeve simultaneously, save the activity duration.I.e. in the first reinforcing bar 191 and
While two reinforcing bar 192 centerings, the first sleeve 181 is enclosed within the first locking plate 171 and the second locking plate 172 outside and by second set
Cylinder 182 is enclosed within outside the 3rd locking plate 173 and the 4th locking plate 174.Because reinforcing bar centralising device 100 enters during installing locking plate
Row reinforcing bar centering, in the case of reinforcing bar centralising device 100 applying power, will connect the first sleeve 181 and the second sleeve of reinforcing bar
182 are installed, and which save the activity duration, improve the efficiency of bar connecting.It should be understood that the first sleeve 181 and second
Sleeve 182 can be tapered sleeve.
