Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a scaffolding rear-mounted water-stop wall connecting piece and a scaffolding rear-mounted water-stop wall connecting structure. Background Art

[0002] During construction, scaffolding is erected to construct or maintain the main structure of a building. Scaffolding wall connections are typically pre-buried steel pipes or pre-buried bolts. However, for scaffolding in older housing renovation projects or projects that require secondary scaffolding, wall connections cannot be effectively installed by pre-buried means and must be installed post-installed. Post-installed wall connections are commonly installed by inserting chemical bolts to secure the base plate to which the pre-buried steel pipes are attached. However, chemical bolts must be left to cure for 24 to 48 hours after grouting. If construction or loading is applied immediately after grouting, the connection becomes unstable, ultimately leading to loosening and cracking. This can hinder the progress of scaffolding installation, increase the risk of scaffolding construction operations, and create safety hazards. Furthermore, pre-buried chemical bolts in newly drilled holes in existing buildings may create a safety hazard of water leakage. Utility Model Content
