Description

Technical Field

[0001] The present application relates to the technical field of construction auxiliary tools, and in particular to a water-stop steel plate bender. Background Art

[0002] Waterstop steel plate is a commonly used waterproof material in construction, mainly used to prevent moisture from penetrating through construction joints; it is made of steel plate, usually coated with anti-rust paint or galvanized to increase corrosion resistance; waterstop steel plate is generally used in basements, pools and other places that require waterproofing. By burying waterstop steel plate in construction joints, moisture leakage can be effectively prevented.

[0003] In order to ensure the waterproof effect of the waterstop steel plate structure, the waterstop steel plates need to be bent at the connection to increase the contact area between the two waterstop steel plates. Since the waterstop steel plates are relatively hard, tools are required for bending. Therefore, a steel plate bending device is disclosed in the prior art, which includes a base, a rectangular groove is provided in the middle of the upper end of the base, which passes through the upper end surface of the base in the left-right direction, and the four corners of the upper end surface of the base are provided with support rods with axes extending in the vertical direction. A top plate is fixedly connected above the support rod, and two hydraulic rods with axes extending in the vertical direction are fixedly provided at the lower end of the top plate. The lower end of the hydraulic rod is fixedly connected to a crossbeam, and a "T"-shaped groove is provided on the crossbeam, which passes through the lower end surface of the crossbeam in the left-right direction and opens downward. The positions of the "T"-shaped groove and the rectangular groove correspond to each other up and down. A punching head is provided at the lower end of the "T"-shaped groove, and a punching die adapted to the punching head is provided at the lower end of the punching head. The punching die is slidably arranged in the rectangular groove along the vertical direction.

[0004] Regarding the above-mentioned related technologies, the steel plate bending equipment disclosed in the prior art can only bend the steel plate at a fixed angle according to the angle of the forming mold below. However, in actual use, it may be necessary to bend the steel plate into different angles, and the steel plate bending equipment in the prior art is relatively bulky and inconvenient to use on the construction site.

[0032] The following is combined with Figure 1-2 This application is described in further detail.

By increasing the force arm, effort is saved and a bending moment is applied to the waterstop steel plate, so that the part of the waterstop steel plate extending out of the plug-in slot is bent. Force is continuously applied to the holding portion 1 until the bending angle of the waterstop steel plate meets the requirements, and then the bent waterstop steel plate is taken out for welding.
