K-type tubular joint loading experiment device

The utility model relates to a K-type tubular joint loading experiment device. The structure of the K-type tubular joint loading experiment device comprises a loading bracket, an actuator and a fixed support, the loading support comprises a horizontal base, vertical columns are arranged at the two ends of the base respectively, and a horizontal cross beam is arranged at the tops of the two columns. Two fixing supports which are distributed up and down are arranged on one of the columns, a downward actuator is arranged on the cross beam, and the lower end of the actuator is used for being connected with the upper end of a main pipe of a vertically-arranged K-shaped tubular joint test piece. The two fixing supports are used for being connected with the ends of two branch pipes of a vertically-arranged K-type tubular joint test piece respectively. The device is simple in structure and convenient to use, a K-type tubular joint test piece can be rapidly installed for an experiment, and the accuracy of an experimen
