[0002] The scaffolding system traditionally used in construction needs to be reliably connected to the building through wall ties. The traditional method of pre-embedded steel pipes is to pre-embed vertical steel pipes inside the concrete, and the wall ties are connected to the pre-embedded steel pipes through fasteners to form a rigid connection. This method requires a large amount of steel pipes and fasteners to be wasted, which is not economically efficient. In addition, premature stress on concrete will cause cracks and other quality problems. In case of a rush project, the pre-embedded Ala nodes must be removed in advance before the secondary structure construction can be interspersed. In this case, the tie points will be removed too early, which will leave major safety hazards to the entire frame. In addition, the pre-embedded tie is not suitable for shear wall structures, which does not conform to the development trend of standardization and tooling in the construction industry.
