[0002] Scaffolding refers to a support made of steel pipes or wooden poles supported by connectors. It is usually used for exterior walls, interior decoration or places with high floor heights that cannot be directly constructed on construction sites. Its main function is to make it more convenient for workers to work at high altitudes, and it can also maintain the safety of workers. Scaffolding is usually fixed to the exterior wall using anchor connections and buckle connections, which basically meets daily needs, but there are still certain defects. Anchor connections generally embed anchor rods into the wall, and the diameter of the anchored steel pipe should be larger than the diameter of the wall plug hole. This method will cause greater damage to the wall. It may even cause cracks in the wall, affecting the progress of the project; the crimping connection is to connect the scaffolding to the wall through the crimping pressure of the scaffolding pipe fittings. A special crimping machine is required for fixing the connection. The installation process is cumbersome, and it is inconvenient to dismantle the scaffolding when adjusting the position, which wastes manpower and material resources. In addition, the accessories at the connection of the existing fixed external scaffolding are often fixed by bolts, which are easy to loosen and cause the external scaffolding to collapse, leading to accidents on the construction site. Sometimes the uneven wall surface will also make the scaffolding unable to be fixed to the wall. Therefore, it is very necessary to design a prefabricated wall connection part for external scaffolding for construction. Utility Model Content
