Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to a retractable prefabricated wall panel installation and positioning device. Background Technology

[0002] The development of prefabricated buildings represents a significant transformation in construction methods, contributing to resource and energy conservation, reduced construction pollution, and improved labor productivity and quality and safety. Therefore, prefabricated buildings are increasingly favored. Prefabricated buildings refer to the transfer of a large amount of on-site work from traditional construction methods to factories. Building components such as floor slabs and wall panels are fabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. During the construction of prefabricated buildings, prefabricated wall panels need to be hoisted and placed in suitable positions relative to the floor slabs according to design specifications. Then, connecting structures are used to connect the prefabricated wall panels to the floor slabs, followed by on-site casting for fixation. During component hoisting, the lower space is confined, making observation difficult. Mirrors are often used to reflect light and facilitate the insertion of pre-reinforced steel bars and holes. However, using mirrors for inspection is inaccurate, requiring repeated adjustments, which is time-consuming, slows down the installation progress, and results in low overall installation efficiency.
