Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially a prefabricated wall pier connecting device. BACKGROUND

[0002] In the field of building construction, prefabricated wall piers, as a common type of building component, have been widely used due to their convenience in construction, effective shortening of construction period, and ease of quality control. However, in the actual installation process of prefabricated wall piers, how to ensure stable and reliable connection with the main structure has always been a key problem to be solved in the construction process.

[0003] In terms of traditional connection methods, expansion bolts are mostly used to complete the fixing operation. This method not only has the disadvantage of low construction efficiency, but also lacks stability in connection strength, making it difficult to meet the reliability requirements for long-term use. Especially in special construction conditions such as narrow and cramped spaces, the limitations of traditional connection methods are more prominent, further increasing the difficulty and challenge of construction.

[0004] For example, the patent with the announcement number CN206554239U discloses a door pier structure applied to prefabricated installation of door and window holes on the side surface of a shear wall. In this patent design, a pre-embedded steel plate is pre-installed inside the door pier, and a through hole is formed on the pre-embedded steel plate. By passing the expansion bolt through the through hole, the connection between the component and the wall is achieved, that is, the assembly process between the door pier and the wall is completed.

[0005] However, after in-depth analysis of this patent technology, it is not difficult to find that it has significant defects: first, since the wall itself does not have a matching pre-embedded structure, additional drilling operations are required at the construction site, and the installation process of the expansion bolt cannot be carried out until the drilling is completed, which undoubtedly slows down the overall construction progress and reduces the construction efficiency; second, the actual contact area between the expansion bolt and the wall is relatively limited, resulting in unstable strength performance at the connection part. Under the condition of long-term load bearing, the wall pier is prone to sagging and deformation, which poses a risk to the safety and stability of the building structure. SUMMARY
