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 invention relates to an anchorage type reaction frame test device suitable for underground space structures, belonging to the technical field of structural tests. Background technique [0002] Structural experiments and structural analysis are verification means to ensure the safe and reliable operation of structures. Structural experiments can verify the rationality of structural forms and the correctness of structural analysis, and provide structural characteristic data to establish new analysis models and engineering theories. Due to its superiority, structural experiments have become a necessary way for researchers to verify structural theories, and the reaction frame is a necessary device for structural experiments. [0003] In order to reasonably arrange the experimental sites, many workshops and teaching laboratories are built on the first floor of the building to reduce their impact on office and experimental activities. Under this condi...
