Description

Technical Field

[0001] This invention relates to the field of concrete cable-stayed bridge construction technology, specifically a safety-protected cable-stayed basket arc head. Background Technology

[0002] The cable-stayed formwork is the most commonly used formwork type in the construction of concrete cable-stayed bridges. Based on traditional diamond formwork, triangular formwork, etc., it incorporates cable stays into the formwork's load-bearing system, transferring part of the load to the main tower structure, so that the main beam and the main tower share the load. This increases the length and weight of the cast-in-place segment and avoids the increase in the main beam cross-section due to construction reasons.

[0003] The primary function of the arched head of the cable-stayed formwork is to transfer the tension force of the stay cables, making it one of the most critical structures in terms of stress distribution and construction. However, the existing arched head structure in cable-stayed formwork construction techniques suffers from the following problems:

[0004] 1. During the construction of different main beam segments using cable-stayed formwork, cranes and manual labor are usually used to adjust the angles of the arc-shaped first and middle tension rods and distribution beams. This method is inefficient, involves working at heights, and poses significant safety risks.

[0005] 2. The tension rods and stay cables in the arc-shaped head are usually connected by threads, which may loosen and pose a certain safety hazard.

[0006] 3. During the construction of concrete cable-stayed bridges, there are situations where the stay cables vibrate due to strong winds, heavy vehicles, collisions between bridge cranes and cranes, or falling objects. The stay cables are connected to the tension rods, and the vibration of the stay cables will affect the stability of the tension rods, which involves the safety of the entire cable-stayed formwork. Currently, there are no vibration suppression and protection measures for the tension rods. Summary of the Invention
