[0002] Continuous beams are statically indeterminate structures, and the internal forces can be solved by force method. There are three or more beams with three supports. Continuous beams have intermediate supports, so their deformation and internal forces are usually smaller than those of single-span beams. Therefore, they are widely used in engineering structures (such as bridges) and mechanical parts. At present, reaction frame devices are often used in continuous beam templates during compression tests.

[0003] However, when the existing continuous beam formwork pre-compression reaction frame is used, if a larger continuous beam formwork needs to be tested, it is inconvenient to carry the continuous formwork, and it is also inconvenient to locate the position where the continuous beam formwork needs to be tested, which not only increases the labor intensity of the staff, but also reduces the efficiency of the continuous beam formwork detection. Therefore, we propose a continuous beam formwork pre-compression reaction frame. Utility Model Content
