Description
Technical Field
[0001] This utility model relates to glass curtain wall accessories, and in particular to a glass curtain wall hanging clamp. Background Technology
[0002] Glass curtain walls, as a common form of modern building envelope, are widely used due to their transparency, aesthetics, and modern appeal. In the installation and construction of glass curtain walls, hoisting is a crucial step. Hoisting clamps are key components connecting the glass panels to the main building structure or hoisting equipment; their performance directly affects the safety, efficiency, and quality of the construction.
[0003] Traditional glass curtain wall hanging clamp systems typically suffer from the following technical defects: (1) Fixed position and inconvenient adjustment: The lifting point positions in many hanging clamp systems are pre-set and cannot be flexibly moved on the main lifting beam. When it is necessary to install glass panels of different sizes or different sections, the entire lifting system must be replaced or repositioned, which is time-consuming, labor-intensive, and has poor adaptability, failing to meet complex and ever-changing construction needs. (2) Insufficient fixing reliability: Some existing adjustable clamps are usually locked only by bolts and nuts. Under long-term use or vibration, this simple mechanical locking is prone to loosening, causing the lifting device to slip slightly in the track. This slippage not only affects the positioning accuracy of the glass, but also brings huge safety hazards, which may lead to stress concentration or even glass falling off. (3) Poor clamping stability and versatility: Traditional clamps have a relatively simple structure and uneven clamping force, which can easily generate excessive concentrated stress on the glass surface, leading to glass breakage. Meanwhile, its clamping range is limited, and it is not well adapted to different thicknesses or types of glass (such as insulated glass and laminated glass). It requires a variety of clamps, which increases construction costs and management complexity. (4) Lack of anti-loosening and anti-slip mechanisms: The fixing of the lifting equipment on the main beam lacks multiple guarantees. Once the main locking mechanism becomes loose, there is no effective auxiliary mechanism to prevent it from continuing to move, and the safety redundancy of the entire lifting system is low. (5) Insufficient protection for glass: If the parts of the clamp that come into direct contact with the glass have high hardness or uneven surfaces, they are very easy to scratch the glass surface or crush the glass when tightening. Although some clamps use shims, their fixing methods and buffering effects are often not ideal, and they cannot achieve a uniform and gentle clamping force distribution.
[0004] Therefore, there is an urgent need in this field for a glass curtain wall clamping system that can achieve rapid and flexible positioning, while possessing high reliability, high safety, and wide adaptability, in order to solve the aforementioned long-standing technical problems.
