Description

Technical Field

[0001] The utility model relates to the technical field of bending auxiliary devices, in particular to an auxiliary device for bending in construction engineering. Background Art

[0002] A construction project is the technical work and engineering entity involved in planning, surveying, designing, constructing, and completing the construction of new buildings, renovating, or expanding their ancillary structures and facilities, as well as the installation of their supporting wiring, pipelines, and equipment.

[0003] In actual construction projects, it is often necessary to bend steel bars or thinner steel plates into a suitable shape and then bury them in the soil. However, existing bending equipment requires workers to hold the materials by hand during the bending process to prevent the materials from shifting, which can easily cause injuries to workers.

[0004] After searching, the patent publication number CN217941692U discloses an auxiliary device for bending in construction projects, including a bender for bending building materials and a fixed plate for fixing the bender, one end of the fixed plate is provided with a sleeve, one end of the sleeve is fixedly connected to a side plate, and one side of the side plate is provided with a second connecting plate, a connecting plate and a second limiting plate hinged in sequence; the material to be bent is placed inside the two side plates, and the material drives the side plates to move downward. At the same time, the second connecting plate hinged at the lower side of the side plate slides along the other end of the second connecting plate and makes the lower surface of the second connecting plate level with the upper surface of the fixed plate. At the same time, the limiting plate and the second limiting plate hinged to each other with the second connecting plate move toward one side of the side plate, and make the lower surface of the second limiting plate contact with the top of the side plate, thereby preventing the bending material from slipping out from the inside of the side plate.

[0005] There are still certain disadvantages in the above patent. The main structure of the bender in the scheme is a disc set on a fixed plate. The disc is provided with a central rod and a side rod close to the edge. When bending, the material needs to pass between the central rod and the side rod for bending, but the upper side of the side rod and the central rod is not blocked. When bending the material, the material is easy to detach from the top of the central rod and the side rod, affecting the normal bending of the material. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a construction engineering bending auxiliary device that can prevent the bending material from detaching from above the center rod and the side rods, thereby ensuring the normal bending of the material.
