Description

Technical Field

[0001] The invention relates to the technical field of building engineering construction, in particular to a portable manual steel bar bending tool. Background Art

[0002] On-site steel bar bending is inevitable, especially at the intersection of special-shaped plates and walls, columns, and beams. Common traditional steel bar bending tools are simply made by workers using scrap steel bars. However, the disadvantage of this tool is that it has no accurate fixed point, the bending angle is too large, and it is more laborious for steel bars with larger diameters.

[0003] Therefore, how to provide a tool that can be used for steel bar bending, is easy to use, can ensure the bending angle, and saves effort even for steel bars with larger diameters has become a technical problem that needs to be further solved in the construction industry. Summary of the Invention

[0004] The purpose of the present invention is to provide a portable manual steel bar bending tool to solve the problems existing in the prior art.

[0005] The technical solution adopted to achieve the purpose of the present invention is as follows: a portable manual steel bar bending tool includes a handrail and a base plate.

[0006] One side of the base plate is welded to the handrail, while the other side is provided with two vertical rods and a lever. The vertical rods and lever are perpendicular to the base plate. The two vertical rods and lever are arranged in a triangle. The two vertical rods form a steel bar clip.

[0007] Furthermore, an external thread is provided on the outer wall of the vertical rod. An adjusting nut is screwed on the vertical rod.

[0008] Furthermore, the handrail is made of Q345 steel, the base plate is made of Q235 steel, and the vertical rod and the pull rod are made of Q235 steel.

[0009] Furthermore, the length of the handrail is 800 mm. The base plate is a square plate. The thickness of the base plate is 1.5 mm. The side length of the base plate is 200 mm. The handrail and base plate are connected by fillet welds, and the weld foot height is 10 mm. The diameter of the vertical rod and the lever is 20 mm and the length is 100 mm. The spacing between the two vertical rods is 25 mm to 36 mm.

[0010] Furthermore, the handrail is provided with anti-slip threads.

[0011] Furthermore, a hanging ring is provided at the tail end of the handrail.

[0012] The technical effects of the present invention are unquestionable:

[0013] A. High precision: the bending angle can be close to 90 degrees.

[0014] B. Simple operation: By adjusting the spacing between the nuts on the vertical rods, the size of the steel bars can be ensured, which can also save effort for steel bars with larger diameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the following examples, but it should not be understood that the scope of the present invention is limited to the following examples. Without departing from the above technical ideas of the present invention, various substitutions and modifications can be made according to common technical knowledge and customary means in the art, and all should be included in the scope of protection of the present invention.

[0018] Example 1:

[0019] When installing special-shaped composite slabs, at the intersection of the beams and slabs on all four sides, at least one side of the composite slab reinforcement cannot be directly anchored into the beam. To solve the overlap problem, the reinforcement needs to be bent and anchored into the beam. The development of this invention is based on the installation of special-shaped composite slabs in prefabricated buildings. Traditional steel bar bending cannot meet the construction requirements of this process. This invention provides a portable manual steel bar bending tool manufacturing and use technology that can ensure the bending angle and bending of larger diameter steel bars.

[0020] See also Figure 1 This embodiment provides a portable manual steel bar bending tool, including a handrail 1 and a base plate 2.

[0021] One side of the base plate 2 is welded to the handrail 1, and the other side is provided with two vertical rods 3 and a lever 4. Both the vertical rods 3 and the lever 4 are perpendicular to the base plate 2. The two vertical rods 3 and the lever 4 are arranged in a triangular shape. The two vertical rods 3 form a steel bar clip.

[0022] See also Figure 2 During operation, the rebar 6 is clamped in the rebar clamp, with the rebar in contact with the lever 4 at the point where it is to be bent. The clamp restricts the lateral displacement of the rebar 6, while the lever 4 serves as a fulcrum for bending, providing a precise location for force application. Rotating the handrail 1 provides torque, causing the rebar 6 to plastically deform at the lever 4. The tolerance is controlled within 3°.
