Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an external wall expansion joint that is easy to install without external nails. Background Technology

[0002] In construction engineering, expansion joints are often installed to prevent additional deformation and stress within the structure caused by external factors, which could lead to cracking and damage. External wall expansion joints, as a type of expansion joint, must meet the deformation requirements of the building structure, such as expansion and settlement, while also ensuring the waterproofing, windproofing, and aesthetics of the exterior wall. Traditionally, external wall expansion joints are covered with metal plates or rubber strips and fixed with exposed fasteners such as nails and bolts. However, existing technology has the following drawbacks: Unattractive appearance: Exposed nail holes or bolts affect the overall aesthetics of the building facade. Complex installation: Requires on-site drilling, welding, or the use of specialized tools, resulting in low construction efficiency. Insufficient durability: Exposed metal parts are prone to corrosion, and sealing materials are prone to detachment after aging, leading to decreased waterproofing performance. Poor adjustability: Difficult to adapt to the needs of expansion joints of different widths, resulting in low versatility.

[0003] Existing technology, such as Chinese invention patent publication number CN115450339A, published on 2022-12-09, discloses a building expansion joint structure and its construction method. The structure includes a first base, a second base, an intermediate cover plate, and a locking device. The locking device includes a support member with a snap-fit ​​seat on its upper part and a rotatable magnetic device on the lower part of the intermediate cover plate, the magnetic device being snap-fitted to the snap-fit ​​seat. A tensioning device is located below the locking device, comprising a connecting seat, a push rod, and a rotating rod. The push rod passes through the connecting seat, and the rotating rod is partially hinged to the connecting seat. The upper part of the push rod is close to the lower side of the intermediate cover plate, and the lower part of the push rod pushes the upper end of the rotating rod to rotate it outwards. Although this patent can seal expansion joints, its installation method is complex, its structure is multifaceted, and its applicability is limited.

[0004] Therefore, there is an urgent need for a solution for exterior wall expansion joints that is simple in structure, easy to install, and requires no exposed fasteners. Utility Model Content
