Description

Technical Field

[0001] The utility model relates to the technical field of scaffold construction, and more specifically to a scaffold wall connecting piece connected by an adjustable pin. Background Art

[0002] In construction projects, scaffolding wall connectors are often used when connecting the scaffolding frame to the main structure of the building. The wall connectors can transmit tension and pressure, and play an important role in strengthening the overall stability of the scaffolding, improving its stable bearing capacity, and avoiding major accidents such as dumping or collapse. The current scaffolding wall connector measures generally adopt the method of pre-embedded steel pipes in the structure, and integrally connected to the scaffolding frame through fasteners and steel pipes. This scheme requires pre-embedded steel pipes in advance, and the exposed length and position of the steel pipes must be kept accurate during the construction process to avoid construction inconveniences and weak structural systems caused by deviations. In the subsequent masonry construction, reserved openings must be reserved in advance, and the steel pipes must be cut at the openings before masonry construction can be carried out. This construction scheme not only affects the construction progress, but also increases the loss of steel pipes. At the same time, the reserved openings in the masonry may also increase the risk of leakage in the exterior wall through later repairs. Therefore, it is necessary to provide a scaffolding wall connector that can improve the efficiency and quality of scaffolding construction and reduce the loss of steel pipes. Utility Model Content
