Description

Technical Field

[0001] The utility model relates to the technical field of anchor pads, in particular to a flat anchor pad. Background Art

[0002] Flat anchor pads are an important component used in prestressed construction. Their main functions and effects are as follows: The main function of flat anchor pads is to disperse the concentrated force generated by prestressed tendons to a larger area during the prestressing process, thereby reducing local pressure and avoiding the damage of anchors or concrete crushing caused by excessive pressure. Flat anchor pads transfer the tension of prestressed tendons to the interior of concrete, ensuring that the prestressed tendons are tightly connected to the concrete structure and work together to improve the bearing capacity and stability of the structure. Flat anchor pads fix the prestressed tendons in the structure through anchoring devices to prevent the prestressed tendons from being displaced or loosened during use, ensuring the safety and reliability of the structure. The use of flat anchor pads helps to improve the bearing capacity, stiffness and durability of concrete structures, so that the structure can perform better when subjected to external loads. The design and manufacture of flat anchor pads take into account the convenience of construction. They have a simple structure and are easy to install, which is conducive to improving construction efficiency. Flat anchor pads are suitable for various types of prestressed concrete structures, such as beams, slabs, columns, shells, etc., and have good adaptability.

[0003] In short, the flat anchor plate plays a key role in prestressed construction. It is an important component connecting the prestressed tendons and the concrete structure. However, the applicability of the existing flat anchor plates is not very good. They can only be used for prestressed steel strands that need to be laterally dispersed. When there is a need to use circular anchors, the flat anchor plates cannot be used. The practicality is not very good. In addition, since the flat anchor plates are steel castings, they are easy to bump into each other during transportation, causing damage to the product. The damage to the anchor plates causes economic losses and easily delays the construction progress. Utility Model Content
