Description

Technical Field

[0001] The utility model belongs to the technical field of bridge span construction and provides a foldable main truss and a foldable triangular hanging basket thereof. Background Art

[0002] Cantilever casting is often used in the construction of large and medium-sized bridge spans, and a triangular hanging basket device is often used in cantilever casting. The commonly used triangular hanging basket device includes a running track beam, a running wheel mechanism, a main beam, main columns, and diagonal stays. Currently, the height distance between the cast-in-place beam and the main beam is small, resulting in limited construction operating space, which affects construction personnel.

[0003] To solve the above problems, a patent document with publication number CN217923149U discloses a triangular hanging basket device, which includes a walking track beam, a walking wheel mechanism, a main beam, a main column and a diagonal brace.

The lower end of the diagonal brace is connected to the main beam, and the upper end of the diagonal brace is connected to the upper end of the main column. A construction operation space is set below the main beam. It also includes a support truss. The walking track beam is detachably arranged on the support truss through a connecting structure. During construction, the support truss is first installed on the cast-in-place beam section, then the walking track beam is installed on the support truss, and finally the other components are installed in sequence. In the height direction, the support truss increases the distance between the cast-in-place beam section and the main beam, thereby effectively increasing the construction operation space and making it more convenient for construction workers to carry out construction.
