Stress beam based on access door groove

The utility model relates to the field of water conservancy facility construction equipment, in particular to a stress beam based on an access door groove. The stress beam based on the access door groove comprises a cross beam, locking beams are arranged at the two ends of the cross beam respectively, the locking beams and the cross beam form a U-shaped structure together, a limiting structure used for being matched with the groove wall of the access door groove in a limiting mode is arranged on the front side and/or the rear side of the cross beam, and inserting holes which are through front and back are formed in the locking beams. And a suspension beam which is in stop fit with the top of the access door groove is inserted into the insertion hole. The cross beam can be limited in the access door groove front and back through the limiting structure on the cross beam, so that the cross beam has the function of bearing front and back traction force, and meanwhile, the cross beam can be supported at the upper
