It can simultaneously test longitudinal and lateral loads. The longitudinal force is transmitted by the pressure rod, and the lateral tension is generated when the side plate flips. Combined with the slide and slider structure, stable movement and buffering are achieved.
It enables efficient and comprehensive load testing of bridge beams and slabs, and can accurately measure lateral tensile forces in windy conditions, thus improving the integrity and safety of the test.

[0002] Bridge beam load testing is a crucial step in road and bridge construction to verify the load-bearing capacity, safety, and performance of beam structures. It directly relates to the overall quality and operational safety of bridges. Its core purpose is to simulate actual loads to detect the mechanical response (such as deformation and stress) and structural integrity of beams under stress, and to determine whether they meet design requirements and standards.
[0003] Current bridge beam load testing equipment has a simple operating structure, usually only conducting longitudinal downward pressure tests, and the support points are not adjustable. In practical applications, the lateral resistance of the beams is large in windy conditions, so lateral tensile force tests are also required. The current load testing capabilities for bridge beams are insufficient. Therefore, this solution proposes a bridge beam load testing device for road and bridge construction. Utility Model Content
