Abstract

The invention discloses a large-scale (continuous) beam-type structure on-site load simulation experiment detection device and detection method. The detection device includes a structural beam arranged parallel to the detection engineering beam. There is a force transmission and detection device between the structural beam and the detection engineering beam. Both ends of the structural beam and the detection engineering beam are connected by wire ropes. The structural beam, detection engineering beam, force transmission, detection device and steel wire rope are composed to realize the simulated load. structural system. After adopting such a mechanism, it is possible to carry out on-site load experiment, detection and inspection of large-scale beam structure engineering. The pulley fixing devices at both ends can meet the requirements of carrying large loads and super large loads. The uniform force and concentrated force can be correctly simulated by adding pad beams and small pads. Lateral instability, the overall equipment structure is simple, which can meet the design and use requirements.

Description

technical field [0001] This patent relates to a large-scale beam structure on-site inspection and simulation technology of actual load action during inspection, specifically a large-scale beam structure on-site load simulation experiment method and device. Background technique [0002] In engineering fields such as water conservancy, transportation, and construction, it is sometimes necessary to test and inspect structural mechanical parameters and performance under on-site simulation of actual loads for large-scale beam structures to verify the reliability of engineering structures. However, at present, there is no certain and uniform method and device at home and abroad that can meet the field load test of this type of project. Especially for large or super large loads and long-span beam structures, it is blank. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and provide a large-scale continuous be...
