Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a combined building expansion joint cover. Background Technology

[0002] Settlement expansion joints are vertical joints installed to prevent damage to buildings caused by uneven settlement of the foundation. Additionally, a cover plate is installed above the joint for waterproofing.
