Loading test system suitable for house type bin side pressure

Abstract

A system suitable for a house type bin side pressure loading test relates to the technical field of anti-seismic tests, and comprises a counter-force device used for applying a vertical load to the top of a test wall body; the device further comprises a load distribution device and a telescopic cylinder. One side of the test wall body is provided with a reaction wall used for horizontally installing the telescopic cylinder, and a load distribution device used for transmitting loads is arranged between the telescopic cylinder and the test wall body; the load distribution device comprises a primary distribution beam which is horizontally arranged, the center position of one side of a beam body of the primary distribution beam is correspondingly hinged to a telescopic cylinder through a horizontal hinge shaft, and a plurality of tertiary distribution beams which can be in corresponding contact with a wall inspection body are arranged on the side, away from the primary distribution beam, of a secondary distribution beam from top to bottom. The third-time distribution beam and the second-time distribution beam are vertically and adjustably connected; according to the utility model, the high-low position of the secondary distribution beam or the tertiary distribution beam can be adjusted according to actual requirements during a test so as to simulate the condition of applying different lateral forces to a test wall, so that the test is closer to the real condition.
