Preferably, the fixed supporting bottom plate is perpendicular to the vertical frame, and the fixed supporting bottom plate is connected with the vertical frame.
Preferably, the fixed supporting bottom plate forms a triangular structure with the vertical frame through the inclined supporting structure, and the fixed supporting bottom plate is connected with the vertical frame through the inclined supporting structure.
Preferably, the front end and the rear end of the lifting device are both provided with rail wheels, and the lifting device is perpendicular to the vertical frame.
Preferably, the brackets are symmetrically distributed around the vertical central line of the vertical frame, and a triangular structure is formed between the brackets and the vertical frame.
Preferably, the support is connected with the fixed supporting bottom plate and the vertical frame.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the test rack is manufactured to simulate the actual effect of using the stairs on floors, so that the stress process of an experiment is closer to the field use effect, the prefabricated stairs of the experiment are placed on steel beams on the test rack to form the effect of a movable support, and the prefabricated stairs are assembled on a construction site to form the movable support, so that the experiment effect can be almost consistent with that of the construction site, and the experiment effect is closer to the reality;
the novel precast concrete stair experimental frame is provided with the support, the stability of the support of the experimental frame can be effectively enhanced through the triangular structure between the support and the vertical frame, the vertical frame is prevented from deflecting, the vertical frame can be effectively kept in a vertical state, and the moving direction and the track of the lifting device can be effectively controlled;
this novel precast concrete stair experiment frame is provided with vertical frame, and the vertical frame that the channel-section steel welding was accomplished can reciprocate by oneself, so adopt the channel-section steel, because the channel-section steel not only can regard as load-carrying members, can regard as the track moreover, has the guide effect.
