Problems solved by technology

Under this condition, the experimental space is relatively narrow, and the effective experimental space provided is limited. At present, most of the known reaction frames are beam-column structures. The reaction frames of this structure occupy a large space and have limited rigidity, so it is difficult to adapt to the limited underground space. Experimental conditions of the structure, inconvenient to use

Abstract

The invention discloses an anchorage type counterforce frame testing device applicable to underground space structures, and relates to the technical field of structural tests. The anchorage type counterforce frame testing device comprises a poured concrete steel square tube upright column, a counterforce frame anchorage system, a tensioner and a stress gauge. The poured concrete steel square tubeupright column is fixedly embedded in a foundation, the tensioner is used for adjusting the tension degree of a draw bar of the anchorage system, and the stress gauge is used for monitoring stress ofthe draw bar. The anchorage type counterforce frame testing device has advantages that the stiffness level of counterforce frames can be greatly upgraded, the load application safety guarantee level can be reinforced, experimental spaces can be effectively saved, and the anchorage type counterforce frame testing device has an excellent application prospect for carrying out structural tests in limited experimental spaces on basement first floors.

Description

Technical field [0001] The present invention relates to the anchor reaction force frame test device suitable for underground space structure, belonging to the technical field test structure. Background technique [0002] Structure experiments and structural analysis to ensure that structures are safe and reliable operation of the verification means you can verify the correctness of the structure of rationality and structure analysis by structural experiments, provide structural characteristic data to create a new model and engineering theory. Experimental structure for its superiority, has become a necessary way researchers verified the theory of the structure, in which the reaction frame structure is essential experimental device. [0003] Reasonable arrangements for the experimental site, a lot of factories and teaching laboratory building was built in the negative layer in order to reduce its impact on office and laboratory activities. Under this condition, relatively small ex...
