Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar positioning devices, and in particular relates to an assembled PC column steel bar positioning device. Background Art

[0002] Modern residential buildings have gradually developed towards the trend of modular installation. This modular installation, as the name suggests, is to complete the various modules of the house, such as bay windows, columns, walls, etc. in the factory, and then transport them to the site for assembly and installation. This greatly shortens the construction time of the building. The PC used in these modules is prefabricated concrete, also called precast concrete. When installing prefabricated panels, workers have almost zero visibility of the reserved holes at the bottom of the panels. They rely entirely on full-time monitoring personnel to use mirrors for visual inspection and gestures to command. In order to improve work efficiency, assembled PC column steel bar positioning devices are needed.

[0003] In a Chinese patent with publication number CN208451902U, a steel bar component positioning device for building PC prefabricated parts is disclosed. The patent forms a positioning function for the steel bar by setting the clamp ring and the clamp ring, thereby effectively solving the problem of inaccurate steel bar positioning and improving the overall quality of the building PC prefabricated parts; however, when the mold and the clamp ring are installed in different positions, the spacing between the steel bar and the mold is also different, which also makes the spacing between the clamp ring and the mold different. However, the above-mentioned steel bar component positioning device is difficult to adjust the distance between the clamp ring and the mold, which makes it difficult for the clamp ring and the mold to be installed and used in different scenarios, and it is difficult to meet daily use, affecting the practicality of the positioning device.

[0004] In order to solve the above problems, this application proposes an assembled PC column steel bar positioning device. Utility Model Content
