    建筑施工

    In engineering construction, springs are commonly used as vibration control components, such as shock absorption springs for building pile drivers and crushers, which can cushion high-frequency vibrations of equipment and reduce impact damage to the machine body and surrounding structures;
    Scaffolding and formwork support systems will use spring supports, which adjust the height and strength of the support through the elasticity of the spring, adapt to the subtle deformation of concrete pouring during construction, and ensure the stability of the support;
    The spring elements in the building settlement observation equipment can maintain the horizontal state of the observation instrument, offset the interference of slight vibrations in the construction site on the observation data, and improve the measurement accuracy;
    When installing curtain walls and fixing pipelines, spring supports can absorb displacement caused by building settlement or temperature changes, avoiding cracking of components due to stress concentration and ensuring long-term structural safety of the building.
