DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The present invention provides a single-sided wall steel bar hook angle bender for underground engineering structures, such as Figure 1-5As shown, it includes a buckle 1: used to contact the end of the hook bar 6, including a first semi-annular claw 1-1 and a second semi-annular claw 1-2, connected by a bolt 1-3, and the caliber size can be adjusted to adapt to hook bars 6 of different diameters; a force transmission rod 2: pulling the end of the hook bar 6, a telescopic rod 2-1 is arranged in the middle, including a first rod body 2-11 and a second rod body 2-12, and the overall length is adjusted by a threaded sleeve 2-13; a rotating disk 3: pulling the force transmission rod 2, and rotating and installing it with the base 4 through the rotating shaft 7, the rotation of the rotating disk 3 can drive the end of the force transmission rod 2 to move, thereby pulling the buckle 1; the base 4: used to install the rotating disk 3, A handle 8 is provided on the outside, and a limiting claw 9 cooperating with the main reinforcement 5 is provided on the inside for stabilizing the base 4; an angle plate 10 is provided on the base 4 outside the rotating disk 3, and is used to mark the rotation angle of the force rod 14 and the rotating disk 3, so as to calculate the bending angle of the hook reinforcement 6; the mounting portion on the buckle 1 is hinged to one end of the force transmission rod 2 through a first connecting shaft 11, and the other end of the force transmission rod 2 is hinged to the edge of the rotating disk 3 through a second connecting shaft 12, and the rotating disk 3 and the base 4 are rotatably installed through the rotating shaft 7. The present invention is also provided with an arc-shaped slide groove 13: it is provided on the outside of the rotating disk 3, and is used to limit the moving trajectory of the second connecting shaft 12.

[0021] Method of use: Sleeve the buckle 1 on the right-angled end of the hook bar 6, so that the end of the hook bar 6 enters between the first semi-circular claw 1-1 and the second semi-circular claw 1-2. The size of the buckle 1 can be adjusted by adjusting the bolt 1-3 to adapt to hook bars 6 of different diameters. Place the base 4 and the rotating disk 3 against the outside of the main bar 5, and stabilize the base 4 on the main bar 5 through the handle 8. Rotate the force rod 14 to drive the rotating disk 3 to rotate, thereby pulling the force transmission rod 2, so that the hook bar 6 is bent and hung on the main bar 5, without manual binding.

[0022] The steel bar hook angle bender is designed according to the actual situation. The hook angle of the prefabricated hook steel bar on the water-facing side is 90°, and the backwater side is bent to the designed angle. After the main bar 5 is tied and fixed, the hook steel bar is hung on the main bar 5 according to the position of the design drawing, and the backwater side is tied and fixed. A handle 8 is provided on the outside of the base 4, and the base 4 and the rotating disk 3 are pressed against the outside of the main reinforcement 5 through the handle 8. The base 4 is installed to clamp the main reinforcement 5, and a retractable force transmission rod 2 with a buckle 1 is provided.
