Description

Technical Field

[0001] The invention belongs to the technical field of building loading tests, and in particular relates to a multi-channel coordinated loading analysis test device for assembled buildings. Background Art

[0002] The mechanical loading test of prefabricated building components and the mechanical analysis experiment of PC components simulate the bearing capacity of the house and the earthquake force through low-cycle repeated loading, and study the strength and deformation of the structural components under the action. It can be convenient for mechanical performance tests of concrete beams, concrete frames, walls, steel structure trusses and other components, and can also be used for column, beam, truss, frame, and node tests. The system can also realize axial compression test, compression shear test, parallel shear test, etc., and is widely used in mechanical performance tests of components, including tension, compression, bending and other tests. It adopts the self-balancing design concept and does not require a reaction groove during installation.

Since the spacing between the positioning holes is consistent, that is, the position where the fixing component is fixed can be determined, the building test wall cannot be adjusted and squeezed, and it is difficult to ensure that different building test walls are accurately and effectively fixed, which affects the accuracy of subsequent loading analysis experimental data.
