Abstract
The utility model relates to a bearing capability tester of a triangular cross section beam; the sides of the triangular cross section beam are movable; the cross sectional angle and structure of the triangular cross section beam are changed by adjusting the connecting length and the position of a side rod, to change the bending section modulus of the beam, so as to change the bearing capability of the beam. Each of three square beams in the beam structure respectively comprises two rectangular cross section steel beams which are combined by a hinge; the beam and the side rods form the triangular cross section beam through bolts; and when in installation, except the side rods on both ends, other side rods cannot be vertical to the beam. The cross sectional angle and structure of the triangular cross section beam are changed by adjusting the length, the positions and the number of the side rods. The bearing capability tester of the triangular cross section beam is used to detect the impact of the changes to the cross sectional angle and structure on the bearing capability of the triangular cross section beam. The device effectively improves the engineering application capability of a student, and simultaneously, can be used to test the bearing capability of the triangular cross section beam in actual engineering.
