Multi-dimensional and multi-directional self-balancing type loading counter-force device

Abstract

The present invention relates to a multi-dimensional and multi-directional self-balancing type loading counter-force device. The device comprises a horizontally closed type counter-force frame horizontally arranged on the ground through support columns; a vertically closed type counter-force frame vertically arranged on the ground, positioned within the horizontally closed type counter-force frame, and mutually and fixedly connected with the horizontally closed type counter-force frame; a distribution beam connected with the horizontally closed type counter-force frame and used for limiting and the counter-force distribution; and a loading base beam respectively connected with the vertically closed type counter-force frame and the horizontally closed type counter-force frame and used for fixing a jack and providing a counterforce. Compared with the prior art, the device is not limited by sites, and can be loaded in multiple directions. Meanwhile, the self-balancing effect of the device is realized without a ground anchor, a shear wall and other limiting devices. After the adjustment and the addition of a simple accessory structure, the device can be applicable to various architectures. Therefore, the test progress can be accelerated, and the cost overhead is saved.

Description

technical field [0001] The invention is applied in the field of civil engineering structure tests, and in particular relates to a multi-dimensional and multi-directional self-balancing loading reaction device. Background technique [0002] The main function of the reaction frame device is to provide reaction support for the structure to be tested during the structural test, so as to ensure the safe and smooth progress of the test. The requirements for the reaction force frame device are simple structure, simple force transmission, convenient installation, reusability and sufficient strength, rigidity and stability. The reaction frame is generally made of steel and fixed on the test bench with anchor bolts. [0003] Usually, the reaction frame only provides vertical or horizontal loads, and the single direction of load application can no longer meet the needs of modern structural tests; at the same time, most reaction frame systems are only applicable to superstructures, and...

AI Technical Summary

Problems solved by technology

[0003] Usually, the reaction frame only provides vertical or horizontal loads, and the single direction of load application can no longer meet the needs of modern structural tests; at the same time, most reaction frame systems are only applicable to superstructures, and cannot be carried out for other special structures such as tunnels. test, poor versatility

With the large-scale and popularization of underground tunnel structure tests, the test capacity of the general-purpose reaction force frame of the existing laboratory is insufficient, and it is necessary to design an additional reaction force frame that conforms to the special shape of the underground tunnel structure, which is obviously uneconomical.

Moreover, most of the current reaction devices need to rely on the reaction wall, but in some cases the requirements of the reaction wall are difficult to meet, thus limiting the site conditions for the test
