Technical Field

[0001] The utility model relates to the field of building construction, in particular to a manual bending tool for stirrups. Background Art

[0002] Stirrups are used to meet the shear strength of the inclined section and connect the main reinforcement and the steel bars of the mixed reinforcement skeleton in the compression zone. They are divided into single-leg stirrups, open rectangular stirrups, closed rectangular stirrups, diamond stirrups, polygonal stirrups, tic-tac-toe stirrups and circular stirrups, etc. Bending tools are required when tightening the stirrups.

[0003] Traditional rectangular stirrups are processed by finished products machinery after being unloaded from the steel bar processing shed.

[0006] Preferably, the pressing and bending device comprises a propulsion shaft, the left end of the propulsion shaft is connected to an adjusting block, the left end of the adjusting block is connected to a rotating block, and the side end of the rotating block is fixedly connected to a plurality of sliding rods.

[0007] Preferably, the propulsion shaft is fixedly connected to the left end of the connecting shaft.

[0008] Preferably, an adjustment groove is provided at the inner end of the limit rail, an adjustment block slides in the adjustment groove, and a sliding rod is connected to the rotation shaft of the adjustment block.

[0009] Preferably, a sliding rod is sleeved in the rotating groove.

[0010] Preferably, a rotating block is provided in the sliding sleeve inside the limiting rail, and the rotating block can be kept parallel to the sleeve tube on the limiting rail.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a pressing and bending device, so that after the stirrup materials for the steel bar processing shed are laid down, they can be directly transported to the plate surface for manual bending. Moreover, since the rotating shaft part is fixed, the stirrups can be adjusted only by pressing the device, so that the adjustment is stable. At the same time, the angle adjustment has a larger adjustment range than manual direct bending, and a larger adjustment range can be adjusted more stably, thereby improving the operating accuracy and adjustment range when the stirrups are bent.
