Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a hanging basket for highway bridge construction. Background Technology

[0002] A hanging basket for bridge construction is a load-bearing device used in cantilever construction. It moves forward segment by segment along the bridge axis, cyclically completing tasks such as formwork erection, rebar tying, concrete pouring, and prestressing tensioning. It is primarily used in the segmented construction of prestressed concrete continuous beams, T-shaped steel structures, and cantilever beams. Anchored to already poured beam segments, it moves forward gradually as construction progresses, providing a working platform for subsequent beam segments. It eliminates the need for scaffolding or large cranes, allowing for segmented cantilever operations directly on-site. It is particularly suitable for large-span bridges spanning deep water, valleys, or complex terrain with grade-separated roads. The hanging basket construction technology is widely used due to its high efficiency and flexibility, greatly improving the quality and efficiency of bridge construction.

[0003] Existing bridge construction formwork uses only anchoring structures to fix the tracks, with no connection between the tracks. Under the weight of the main truss, this makes it prone to separation or displacement. The anchors in existing bridge construction formwork do not penetrate the tracks, failing to further secure them to the bridge structure, resulting in poor stability. After long-term use, this may lead to plastic deformation or structural fatigue, reducing load-bearing capacity. Furthermore, the suspension system of existing bridge construction formwork is not securely connected to the main truss, making it susceptible to displacement or deformation of the spreader beam due to the weight of the load. Deviations in the weight of the suspension system can cause the formwork to overturn, potentially leading to a fall accident. Utility Model Content

[0004] The purpose of this utility model is to provide a hanging basket for bridge construction in highway construction, which adds a more stable connection structure, effectively improves the load-bearing capacity of the hanging basket, and uses limit blocks to prevent the hanging basket from tilting, thus ensuring construction safety.

[0005] To achieve the above objectives, this utility model provides the following solution: A hanging basket for highway bridge construction includes a traveling system, a main truss, and a suspension system. The traveling system is anchored to the bridge structure, and the top guide rail of the traveling system is connected to the main truss. The suspension system is fixed to the main truss.

The traveling system 1 is anchored to the bridge structure, enabling the formwork to move along the bridge deck. A guide rail at the top of the traveling system 1 connects to the main truss 2, which serves as the primary load-bearing structure. The main truss 2 is typically composed of channel steel or angle steel, often employing a stable right-angled triangular structure. The suspension system 3 is fixed to the main truss 2, supporting the construction formwork and bearing its weight, ensuring the stability and positional accuracy of the formwork during pouring. The traveling system 1 includes splicing rails 11 and anchoring structures 12. Two sets of splicing rails 11 are provided, located at the left and right ends of the traveling system 1 respectively. The splicing rails 11 facilitate the cyclical laying of rails and are used to support and guide the movement of the main truss 2. The anchoring structures 12 are located at the bottom of the splicing rails 11 and are riveted to the bridge structure, thus fixing the splicing rails 11 to the bridge structure. The splicing track 11 includes a track body 111, a splicing joint 112, and a splicing groove 113. The splicing track 11 is composed of several track bodies 111.
