Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a ground deformation joint structure at the junction of the main building and the connecting corridor. Background Technology

[0002] In large public buildings, commercial complexes, hospitals, schools, factories, logistics facilities, and other building complexes, connecting corridors serve as vital transportation links, serving as elevated passageways connecting multiple buildings with different functions. Connecting corridors (outdoor or semi-outdoor) and the main building (indoor) are typically designed as independent structural systems. Expansion joints must be installed at their junctions to effectively accommodate differential settlement, temperature deformation, and relative displacement caused by seismic forces. Furthermore, due to significant differences in the ground construction methods of the two parts, although the elevation difference can be bridged by accurately calculating the elevations of the structural slabs on both sides, traditional expansion joint methods still struggle to achieve an ideal smooth ground transition.

[0003] Currently, the common practice in this area is to install metal covers or embed V-shaped or W-shaped rubber sealing strips at the 100-200mm wide seam. While this traditional technique is simple in construction, it has inherent drawbacks, such as: difficulty in precisely adapting to complex elevation changes, poor flatness and safety; insufficient durability, with exposed metal covers prone to corrosion and deformation, and rubber sealing strips prone to aging and cracking; its appearance clashes with sophisticated interior decoration and outdoor landscaping, affecting the overall aesthetics; and after long-term use, components are prone to loosening and deformation, leading to a decline in sealing, insulation, and waterproofing performance.

[0004] Therefore, a new type of expansion joint construction method is needed. It can effectively solve the problem of flush joints caused by the difference in indoor and outdoor elevations, and can also achieve reasonable structure, simple construction, moderate cost, adaptability to deformation, and simultaneous improvement of durability, safety and aesthetics.
