Description

Technical Field

[0001] The invention belongs to the technical field of building engineering construction, and in particular relates to a crescent-shaped hanging basket suspension bracket system and a construction method thereof. Background Art

[0002] A hanging basket is a construction tool used for aerial work in construction projects. It is frequently used in the construction of exterior walls, curtain wall installation, insulation, and exterior wall maintenance and cleaning of multi-story buildings. A hanging basket can replace traditional scaffolding, reducing labor intensity, improving work efficiency, and is a new type of reusable equipment for working at height. The suspension bracket is one of the most important components of a hanging basket. The bracket can be divided into standard and special types, which are further divided into cantilever and pull-rod types. Commonly used suspension brackets in construction projects include counterweight suspension brackets, parapet clamps, and special types such as riding suspension, which are derived from the above two types. These three types of brackets are primarily used on flat roofs and cannot be directly applied to sloping roofs. Their main disadvantages include relatively cumbersome installation and removal requiring the coordination of machinery, significant impact on other post-installation operations, poor connection to the structure resulting in significant safety risks, and an inability to adequately address the overturning of sloping roofs.

A method for constructing a crescent-shaped hanging basket suspension support system according to any one of claims 1 to 9, comprising the following steps: Step 1: Connect two groups of first embedded rods (5.2) to the first anchor plate (5.5), connect two groups of second embedded rods (6.2) to the second anchor plate (6.4), and assemble the front support leg (2); at the same time, tie the prestressed steel cable (4.2) on the cantilever beam unit (4.1), and apply prestress to the prestressed steel cable (4.2); then temporarily connect the two cantilever beam units (4.1) using the first tie bolt (4.3) and the second tie bolt (4.4); Step 2, constructing the slope roof structure (1): when constructing the roof panel (1.1), installing the front support (5) and the rear support (6) on the roof panel (1.1); Step 3: Install the front support leg (2) and the rear support leg (3) on the front support (5) and the rear support (6) respectively; Step 4: Install the cantilever beam unit (4.1): Connect the two cantilever beam units (4.1) to the front support leg (2) and the rear support leg (3) respectively. This completes the construction.
