Description

Technical Field

[0001] This utility model relates to the technical field of scaffolding wall ties, specifically an adjustable disc-lock scaffolding wall tie. Background Technology

[0002] With the increasing demands for scaffolding safety in the construction industry, socket-type disc-lock steel pipe scaffolding has become the mainstream scaffolding form for complex structures such as super high-rise buildings and large-span structures due to its advantages such as reliable node connections, high load-bearing capacity, and fast erection efficiency. As a key force-transferring component between the scaffolding and the main building structure, the rationality of its installation method directly determines the scaffolding's anti-overturning capacity and overall stability. According to the mandatory provisions of the "Safety Technical Standard for Socket-Type Disc-Lock Steel Pipe Scaffolding in Building Construction" (JGJ / T 231-2021), wall ties must be installed horizontally. When horizontal installation is not possible, they must be connected diagonally downwards to one end of the scaffolding; upward diagonal connections are strictly prohibited.

[0003] Existing disc-lock scaffolding wall ties mostly employ traditional rigid connection methods. This involves pre-embedding steel pipes, bolts, threaded sleeves, or installing post-installed bolts within the main building structure, followed by rigid connection of the scaffolding to the pre-embedded components using fixed-length steel pipes, couplers, or structural steel. However, in actual construction, due to factors such as construction errors in the main structure, positioning deviations of the pre-embedded components, and limitations of modular step distances in the disc-lock scaffolding, a certain deviation generally exists between the center of the pre-embedded components and the center of the scaffolding connection disc. This results in traditional rigid wall ties being unable to be installed horizontally, and forced connections easily creating an upward tilt angle, violating specifications. Furthermore, there are problems such as difficulty in ensuring the quality of on-site cutting and welding, low turnover rate due to the inability to fine-tune the length, and difficulties in dismantling and modification, affecting construction efficiency. The few existing adjustable solutions mostly use a single threaded sleeve for adjustment, which has drawbacks such as limited adjustment range, inability to adapt to multi-angle deviations, and low installation and dismantling efficiency, making it difficult to meet the standardized, tool-based, and efficient construction needs under complex on-site conditions.

[0004] Based on this, an adjustable disc-lock scaffolding wall tie is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
