Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a wrench capable of bending a single-limb hoop on a wall column into 135 degrees and a manufacturing method thereof. Background Art

[0002] In building construction, the bending of single-leg stirrups for frame columns and hidden shear wall columns is a link with high technical requirements. In traditional construction methods, one end of the single-leg stirrup is usually processed into a 135° hook and the other end is processed into a 90° hook for easy construction and installation. However, one end of the 90° hook needs to be bent to 135° after installation to meet the specification requirements. This process may become difficult due to the interference of other steel bars in the wall column, and it is difficult to bend the single-leg stirrup to the required angle with ordinary tools. Summary of the invention

The present invention provides a wrench and a manufacturing method that can bend a single-leg hoop on a wall column to 135°, which can effectively improve the bending accuracy of the single-leg hoop, ensure the construction quality, and also reduce the labor intensity of workers.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] A wrench capable of bending a single-leg hoop on a wall column to 135 degrees comprises a handle and a sleeve. The handle is L-shaped and comprises a long side and a short side. One end of the sleeve is installed on the outside of the short side. The length of the long side is more than 6 times that of the short side.

[0006] Preferably, the material of the handle is steel bar.

[0007] Preferably, the diameter of the steel bar is 20 mm.

[0008] Preferably, one end of the sleeve is welded to the outer side of the short side of the handle.

[0009] Preferably, the sleeve is an M20 nut.

[0010] Preferably, the sleeve is welded in the middle of the short side.

[0011] Preferably, the length of the long side is 420 mm, and the length of the short side is 60 mm.

[0012] The present invention also discloses a method for manufacturing a wrench capable of bending a single-limb hoop on a wall column into 135 degrees, comprising the following steps:

[0013] Bend a 20mm diameter steel bar into an L shape, with a straight section of 6cm after bending;

[0014] Weld the straight section of the L-shaped steel bar to the M20 nut to form a wrench.

[0015] Beneficial effects:

[0016] The present invention can effectively perform secondary bending on the single-leg hoop on the wall column, and can be easily bent to 135 degrees, so that on-site construction can meet standard requirements, can effectively improve the bending accuracy of the single-leg hoop, ensure construction quality, and also reduce the labor intensity of workers.
