On the one hand, engineering tests are a means of evaluating engineering quality defects, identifying and preventing engineering quality accidents. It can improve the quality of engineering construction and ensure the smooth progress of the project. On the other hand, engineering tests are a necessary means of scientific research in structural engineering. For example, new theories, new processes, and new materials are inseparable from the verification of engineering tests. The reaction frame is an important part of the engineering test loading device. The reaction frame provides and transmits the reaction force, applies the required load to the test piece, and ensures the smooth progress of the test. At present, the reaction frame used in the laboratory is mainly composed of beams, columns, bases, lifting systems, hydraulic systems, adjustment pads, etc. The reaction frame specimen group belongs to the specimens of mechanical engineering and structural testing mechanical equipment. At present, it is used in artificially built brackets, with complex structures and poor stability, which makes it easy to make errors during installation; the diagonal brace is long and prone to bending and deformation. This is to measure the force or the weight under the action of another force, and receive the same reaction force, support the heavy mass reaction frame, bear the pressure size analysis and gravity size analysis of the other party, ensure the stable operation of the reaction frame, achieve the optimization of the reaction frame, adjust the size of each component, and test the various force indicators of the reaction frame.

[0003] Existing technology, such as: CN218147854U A modular reaction frame structure for closure and top-pushing of a rigid frame bridge. Before locking and fixing, the inner sleeve of the steel box beam is movably inserted into the outer sleeve of the steel box beam, which is convenient for adjusting the length of the steel box beam sleeve to adapt to closures of different lengths. An end stiffener is welded and fixed between the top-pushing end seat plate and the outer side wall of the inner sleeve of the steel box beam, and an end stiffener is also welded and fixed between the outer side wall of the rear end of the outer sleeve of the steel box beam and the embedded seat plate. The embedded seat plate is fixedly connected with the end embedded anchor steel bars embedded in the segmental box beam. The first ear plate seats are fixed on the outer walls around the end of the outer sleeve of each steel box girder, and the second ear plate seats are fixed on the outer walls around the front end of the inner sleeve of each steel box girder.

[0004] However, the device still has certain shortcomings during use. When adjusting the height, the reaction frame structure unit is still inconvenient to adjust. It can only be adjusted by the jack, and the jack needs to be operated manually, which makes the jack prone to instability. If there is a height difference, the work safety and work efficiency are seriously reduced. At the same time, after the device is fixed, due to the lack of auxiliary support, the pressure is easily concentrated in one place, which reduces the service life, and has limitations when fixing, reducing practicality.
