Reaction force device with combination of anchor bars and steel beams

The utility model relates to a reaction force device with combination of anchor bars and steel beams. The reaction force device comprises a plurality of jacks, a plurality of anchor bars, a plurality of steel-bar pulling rods, a plurality of disc-shaped steel plates, rigid-frame brackets, weight steel beams, a main beam, a stress piece and a measuring instrument, wherein the anchor bars are arranged on pile heads and a bottom plate needing to be loaded with the weight steel beams; one disc-shaped steel plate is arranged on each pile head; all the disc-shaped steel plates are provided with the jacks; each steel-bar pulling rod is connected with the corresponding anchor bar by a pair of butt-joint bolts; each steel-bar pulling rod is provided with the stress piece; the rigid-frame brackets are arranged on the bottom plate at the two sides of the position needing to install the weight steel beams; the weight steel beams are arranged on the jacks; the main beam is erected on the weight steel beams; the steel-bar pulling rods and the main beam are fastened by bolts to press the weight steel beams; and the measuring instrument is arranged on the bottom plate. The reaction force device is applied in the construction of building engineering, the detection test of a base pile is finished in the built small-space range of the bottom plate, the time and the labor are saved and too-large space is not needed.
