AI Technical Summary
Existing carbon fiber pull-out testing instruments are not adaptable enough to building roof frames with different curvatures, and their installation and operation are not convenient in space-constrained scenarios, making it difficult to complete the test efficiently.
A pull-out device for carbon fiber testing was designed, which uses a steel test block directly bonded to the carbon fiber layer of the building's roof frame. Stable testing is achieved through pull-out components and installation components, including a positioning plate, threaded rod, guide rod, and pre-embedded screw, etc., which can adapt to buildings with different curvatures and simplify the installation process.
It improves the structural adaptability and ease of installation of the test, ensuring the accuracy and reliability of the test results, especially in space-constrained building rooftop scenarios where testing can be completed efficiently.
