We know that whether it is for the use of prestressed anchors or other related products, in order to achieve better application results, we must first fully understand the relevant knowledge, in order to better help everyone The technical knowledge of Zhejiang Anchor Technology's technicians on the application of prestressed anchors in bridges is as follows:
    (1) Selection of materials: The material is the source of the quality of prestressed anchors. The advantages and disadvantages of the materials have a great influence on the anchor clips, that is, the same steel number. The different materials of the manufacturers vary greatly, resulting in the production of anchors. The quality is unstable.
    (2) The technical content of the anchor is very high: the producer must be qualified: the specifications and dimensions of the prestressed anchors of different varieties and the technical parameters such as the form, size, angle and tooth shape of the clip are determined by the design. The content is very high, it is not free to produce, it must be processed according to the design drawings, and the production of anchors must be qualified.
    (3) Heat treatment process and hardness index of anchor clip: The purpose of heat treatment is to improve the hardness of anchor parts. Due to the difference of heat treatment process, the difference in material selection is large, and the influence of the hardness of anchor clips increases during heat treatment. Big. The national standard GB/T14370 only specifies the ratio of the hardness of the anchor clips to be inspected and sampled, but the specific hardness index is not specified.
