Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to an angle-adjustable rhomboid hanging basket main truss. Background Technology

[0002] Long-span prestressed concrete continuous beams are widely constructed using cantilever formwork. Cantilever formwork construction refers to the on-site, segmented cantilever operation using a suspended formwork system when pouring cantilever beams. Generally, truss-type cantilever formwork can be divided into four types: triangular, rhomboid, bowstring, and flat chord unbalanced formwork. Due to its simple structure, clear stress distribution, high overall stiffness, and small deformation, the rhomboid formwork has become the mainstream product in cantilever construction technology.

[0003] When using rhomboid hanging baskets for cantilever construction, for bridges with different designed beam spans, the same beam segment is usually divided into multiple cantilevered segments of different lengths. Different segment lengths correspond to different specifications of hanging baskets. The existing rhomboid hanging basket cantilever construction has the following problems: the construction of bridge segments requires rhomboid hanging baskets with different specifications of components. However, the structure of rhomboid hanging baskets is fixed and not universal, resulting in a variety of rhomboid hanging basket components of different specifications and quantities, which is not conducive to turnover and transportation.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Compared with the fixed structure and poor versatility of existing diamond-shaped hanging baskets, this utility model allows the second mounting hole to be connected to the first mounting hole at different positions and then inserted with a pin after the front upper box is slid to the required angle. This can change the angle of the main truss of the diamond-shaped hanging basket, making it suitable for different specifications of diamond-shaped hanging baskets and thus applicable to the construction of bridges of different segments, saving resources and facilitating transportation.
