Description

Technical Field

[0002] Currently, in architectural decoration projects, to prevent cracks or damage to building components due to climate temperature fluctuations (thermal expansion and contraction), a structural joint, known as an expansion joint, is typically installed at an appropriate location along the construction joint of a building or structure. This expansion joint divides building components above the foundation (such as walls, floors, and roofs) into two independent sections, allowing the building or structure to expand and contract horizontally along its length, thus preventing cracks caused by climate change.

In order to meet the requirements for expansion joint setting, filling materials such as asphalt, hemp, and foam plastics are generally used. The expansion joint surface layer is usually covered with metal materials such as aluminum plates or stainless steel, resulting in low construction efficiency and poor waterproof stability and decorative effects.
