Description

Technical Field

[0001] This utility model belongs to the field of anchor technology, and specifically relates to a novel anti-detachment anchor. Background Technology

[0002] An anchor is a tool used to fix an object. In prestressed concrete structures, anchors serve to fix the prestressing tendons, so that the prestressing tendons can be held in a specified position after tensioning, thereby establishing prestress in the concrete structure.

[0003] When tensioning prestressed tendons, the initial tension is first applied from zero to the point where the elongation value is measured. After reaching the initial tension, the pressure value of each subsequent loading stage can be divided according to the tension force required by the design. The purpose of staged tensioning is to more accurately control the application process of prestress and avoid stress abrupt changes that could damage the anchorage and prestressed tendons. Stress control is achieved by controlling the tension force through the pressure gauge reading of the tensioning equipment, while elongation verification is performed by measuring the elongation value of the prestressed tendons during the tensioning process.

[0004] Since the required prestress varies in different usage environments, the clamping tightness of the prestressing tendons needs to be adjusted when tensioning the anchorages and prestressing tendons to prevent them from falling off due to excessive prestress. However, existing anchorages do not have the ability to adjust the clamping tightness of the prestressing tendons, which can easily affect the performance and load-bearing capacity of the anchorages.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
