Description

Technical Field

[0001] This utility model relates to the field of building material testing equipment, and in particular to a static load test device for light steel keel impact resistance. Background Technology

[0002] As the core framework material for ceilings and partitions in modern buildings, light steel keel must withstand complex and diverse mechanical forces, such as impact forces and static loads, in practical applications. However, existing testing equipment has many shortcomings in performance, making it difficult to meet the testing requirements for the comprehensive mechanical properties of keel. Traditional impact equipment struggles to precisely control the impact force, often causing excessive damage to the keel and failing to accurately reflect its performance. This not only affects the accuracy of test results but also hinders the evaluation and optimization of material quality. Furthermore, current static load application carrier devices are mostly single-mode, lacking flexibility and unable to effectively simulate keel performance under different stress conditions, limiting the applicability of the testing equipment. In addition, most testing devices are incompatible with various specifications of light steel keel, the clamping process is time-consuming, and the testing efficiency is low, seriously affecting the progress of building material research and development and quality control. Therefore, there is an urgent need for a testing device with precise impact force control, flexible static load application, high versatility, and ease of operation to achieve comprehensive and efficient testing of the mechanical properties of light steel keel.
