Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing and steel bar on-site construction, and more specifically to the technical field of a portable on-site stirrup bending tool. Background Art

[0002] Generally, stirrups are processed centrally and then sent to the construction site for placement and binding. However, sometimes, due to the need for on-site bending in special areas and special structures, and in order to facilitate on-site installation of stirrups at the intersection of nodes, the stirrup hooks are not bent into place at one time, resulting in the need for secondary on-site bending of the stirrup hooks. Due to the different design angles of the stirrup hooks and the dense steel bars on site, the stirrup hooks cannot be bent into place.

[0003] How to effectively bend stirrups on site to make them easy to carry, save effort in use, and ensure the forming quality of the stirrups has become an issue that needs to be addressed urgently. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and provide a portable on-site stirrup bending tool.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] The utility model provides a portable on-site stirrup bending tool, comprising a bending force-bearing component matched with the stirrup and a lever force-applying component fixedly connected to the bending force-bearing component, a receiving slot with a width greater than the stirrup diameter is arranged on the bending force-bearing component, and a bending groove is arranged on one side of the receiving slot.

[0007] In one embodiment, the bending force-bearing component includes a bending piece, the bending piece is a barrel-shaped body, the accommodating seam is arranged along the length of the barrel-shaped body, and the cross-sectional width of the accommodating seam is 1 / 2 arc.

[0008] In one embodiment, the bending groove is located in the middle of one side of the accommodating slot, and the lever force applying component is located outside the barrel-shaped body away from the side of the bending groove.

[0009] In one embodiment, the bending groove is a secondary stepped groove, and the width of the primary step of the secondary stepped groove is greater than the width of the secondary step.

[0010] In one embodiment, the bending member is made of steel.

[0011] In one embodiment, the lever force applying component is a rod-shaped handle, and the cross-section of the rod-shaped handle is one of circular, triangular, square or elliptical.

[0012] In one embodiment, a plurality of anti-skid knurling patterns or a plurality of arc-shaped anti-skid grooves are evenly distributed on the outer wall of the rod-shaped handle.

[0013] In one embodiment, the anti-skid knurling and anti-skid grooves are located in the gripping area of ​​the rod-shaped handle, thereby achieving anti-skid, making the tool more anti-skid and more labor-saving to use. If the rod-shaped handle is made of waste threaded steel bars, this is not necessary because the waste steel bars have threads.

[0014] In one embodiment, the axis of the rod-shaped handle is arranged orthogonally to the axis of the barrel-shaped body.

[0015] In one embodiment, the rod-shaped handle is connected to the barrel-shaped body by full welding, and the material of the rod-shaped handle is solid steel.

[0016] Specifically, the rod-shaped handle is the part that workers hold in their hands, and is connected to the barrel-shaped body by full welding (located in the middle of the bending part). In order to prevent the handle from deforming and breaking during use, the rod-shaped handle is made of solid steel (alloy steel) into a cylinder or ellipsoid. In order to facilitate the use of force, the upper part of the handle is generally designed with an arc-shaped anti-slip groove, which cooperates with the bending part to achieve the bending of the steel bar through the principle of leverage. The rod-shaped handle can be made on site from waste high-strength threaded steel bars.

[0017] In one embodiment, the length of the rod-shaped handle is 4-8 times the length of the bending member.

[0018] The beneficial effects of the utility model are as follows:

[0019] The utility model has a reasonable design. Through this portable on-site stirrup bending tool, it can be conveniently carried and better portable, and can meet the bending of stirrups in different scenes and different areas during different on-site construction processes. It is faster and more labor-saving, has a good bending effect, and can be made of waste steel bars and sleeves on site, and the waste can be reused. At the same time, the stirrup hook can be effectively bent to the designed angle through the bending groove, which can effectively ensure the bending quality of the steel bar.
