The utility model discloses the screw thread of being connected with last horizontal pole on the compression bar is clockwise top spin screw thread, and the screw thread of being connected with the sheer pole on the compression bar is clockwise bottom spin screw thread. The aligning hammer is a cuboid. The width of the U-shaped groove base is at least 5mm wider than that of the straightening hammer.
The utility model is used for the alignment of job site reservation reinforcing bar during the use, the reinforcing bar that will straighten is placed in U type inslot and is located alignment hammer below, through rotating rotatory card, makes the compression pole order about the downward movement of alignment hammer, and the clearance between alignment hammer and the U type tank bottom reduces gradually until pressing on crooked reinforcing bar, straightens the reinforcing bar. After the reinforcing steel bar is straightened, the rotating clamp is rotated reversely to drive the straightening hammer to lift upwards, and the straightened reinforcing steel bar is taken out. And repeating the steps until the reinforcing steel bars are completely straightened.
The utility model discloses but quick alignment reserves the reinforcing bar, and is easy and simple to handle and reliable, can promote the efficiency of construction by a wide margin, reduces workman intensity of labour. Meanwhile, the U-shaped groove and the straightening hammer are matched, so that the straightened steel bars can be straightened smoothly, and the standard of finished products of the steel bars is far higher than that of the steel bars straightened manually by workers.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is the schematic view of the utility model during the straightening of the reinforcing bar.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the reserved steel bar straightening device comprises an upper cross rod 2 and a lower cross rod 11 which are arranged in parallel, vertical support rods 3 which are symmetrically arranged at two ends of the upper cross rod and the lower cross rod and have the supporting rod function, vertical compression rods 4 which are assembled in the middle of the upper cross rod and the lower cross rod, a U-shaped groove base 9 arranged at the bottoms of the two support rods, a straightening hammer 8 which is arranged below the lower cross rod and can fall into the U-shaped groove, and two vertical connecting rods 7 which are connected with the straightening hammer and the lower cross rod. The both ends of sheer pole one side have welded horizontal pole sleeve pipe 6 respectively, the sleeve pipe 6 is passed to the lower part of bracing piece 3, and the bracing piece bottom welds on a curb plate top of U type groove base, and the upper end of bracing piece welds in upper beam one side both ends. Go up horizontal pole and sheer pole's centre and all be equipped with a horizontal pole go-between 10 of taking the internal thread, the upper portion and the lower part of compression pole 4 are processed respectively and are had the screw thread with horizontal pole go-between internal thread fit, the compression pole from the top down passes horizontal pole go-between 10 on horizontal pole and the sheer pole in proper order and respectively with last horizontal pole and sheer pole threaded connection, wherein, the horizontal pole go-between internal thread of horizontal pole and the internal thread direction of horizontal pole go-between of sheer pole are opposite, in this embodiment, the screw thread of being connected with last horizontal pole 2 on the compression pole is clockwise top spin screw thread, the screw thread of being connected with sheer pole 11 on the compression pole is clockwise bottom spin screw.
