Abstract

Technical Field
[0001] The utility model belongs to the technical field of construction auxiliary equipment, and more specifically relates to a ladder cage supporting wall connecting device which is easy to install and disassemble. Background Art
[0002] At present, the construction of tall piers in highway bridge construction often requires the construction of ladder cages. In order to allow construction workers to go up and down to construct the piers, the ladder cage is often connected to the embedded parts on the surface of the pier through metal connecting pipes, thereby ensuring the stability and safety of the ladder cage. As a connection structure, the metal connecting pipe is often bolted to the ladder cage through a connecting piece at one end and bolted to the embedded parts through a connecting piece at the other end. After long-term use, the nuts often become loose, affecting the safety of the ladder cage. Therefore, in traditional processes, multiple sets of metal connecting pipes are often used for support at the same horizontal height, which results in multiple sets of connecting pieces and multiple embedded points embedded on the surface of the pier, which will cause more repair surfaces for later construction. For piers that do not require later repairs, it will affect the first-time construction pass rate of the pier.
