Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a quick connection structure for prefabricated buildings. Background Technology

[0002] Prefabricated construction, as an innovative building model, transfers a large amount of on-site work to factories. Various building components and accessories are prefabricated in factories and then transported to the construction site for assembly and installation using reliable connection methods. Rapid connection structures, as one of the core technologies of prefabricated construction, are undeniably important. They aim to achieve efficient and precise connection of building components on the construction site, significantly shortening the construction cycle, reducing labor costs, and improving building quality. Rapid connection structures enable components to be quickly and stably joined, ensuring the strength and stability of the overall structure of the prefabricated building, and providing strong support for the widespread application of prefabricated construction.

[0003] During the use of connection structures, due to dimensional deviations during factory prefabrication and collision deformation during transportation, it is difficult to accurately align components on site. The positions of the reinforcing bars and prefabricated sleeves may shift. When the shift is partial, the reinforcing bars can barely be inserted; when the shift is complete, the components need to be reprocessed, affecting work efficiency. Existing equipment uses positioning fixtures and measuring instruments to accurately position components during installation. For components with small dimensional deviations, the hole positions are adjusted and appropriate cutting is used to correct the deviation. Adjustable sleeves are used to adjust the relative positions of the reinforcing bars and sleeves within a certain range to avoid positioning difficulties. However, the above structure does not take into account the complexity of connection structures, making it impossible to quickly assemble the structure, reducing the convenience of connection. Furthermore, the number of connection structures is limited, and the stability is insufficient, failing to meet diverse connection needs. Utility Model Content
