Embodiment 1

[0064] This embodiment provides a reaction force frame, which includes: a supporting unit, a loading unit, a load uniforming unit, a lifting unit and an auxiliary supporting unit. The loading unit is arranged on the support unit and applies load to the loaded piece; the load uniform unit is arranged between the loading unit and the loaded piece, and is used to evenly apply the load applied by the loading unit to the loaded piece. It should be noted that, if figure 1 As shown, the loaded part in this embodiment is the staircase 2 . Wherein the staircase 2 is also connected with the displacement display, and the sinking amount of the staircase 2 can be displayed through the displacement display. Of course, the object to be loaded can also be other objects that need to be subjected to static tests. By providing the load uniform unit, it is possible to effectively prevent the occurrence of stress concentration of the loaded part due to the load applied by the loading unit.

Abstract

The invention discloses a reaction frame and a method for adopting the reaction frame for performing static testing. The reaction frame comprises a supporting unit, a loading unit and a load uniform unit, wherein the supporting unit comprises at least two supporting columns, and the loading unit is arranged on the supporting unit and applies loads to a piece to be loaded; the load uniform unit isarranged between the loading unit and the piece to be loaded and used for uniforming the loads applied to the piece to be loaded by the loading unit; the supporting unit can rotate around the axis ofat least one supporting column. By arranging the load uniform unit, the phenomenon that stress concentration is caused due to the fact that the loads are applied to the piece to be loaded by the loading unit can be effectively avoided; meanwhile, the supporting unit is rotatable, the supporting unit is rotated so that a testing region below an electric hoist hook is not blocked, the piece to be loaded is convenient to transport, and the hoisting requirement for the piece to be loaded is lowered.

Description

technical field [0001] The invention relates to the technical field of static test equipment, in particular to a reaction force frame and a method for carrying out static force tests using the reaction force frame. Background technique [0002] When other industries such as the construction industry conduct static tests on building formwork or other formwork, due to the high height and wide area of ​​the formwork, it is usually necessary to manufacture a special test reaction frame. The reaction frame can provide external load and restraint reaction force for the formwork. The existing reaction frame usually needs to have the following characteristics: easy to operate, strong flexibility, simple force transmission in the overall structure, convenient disassembly and assembly, and sufficient strength, rigidity and stability. [0003] Chinese patent document CN206862607U discloses a novel structural static test loading test frame. It consists of a supporting column, a combin...
