Problems solved by technology

[0005] 1. The existing loading reaction device is relatively easy for in-plane loading, but difficult for multi-angle loading in space
[0006] 2. The existing loading reaction devices and auxiliary components have poor versatility. In order to complete the multi-directional loading test of the node space, they are all designed according to the specific node specimen. After the test is completed, they are basically scrapped and cannot be reused, causing great damage. waste of resources
[0007] 3. The existing loading system is still relatively backward in synchronous automatic loading and data acquisition technology, and generally requires multiple people to operate the loading jack separately

Abstract

The invention discloses a spherical all-dimensional loading device used for a building structural node test, comprising a spherical steel structure counterforce frame, a loading, positioning and adjusting wheeltrack system, a jack hydraulic servo loading system and a console. In the invention, spatial all-dimensional loading and data acquisition on a node test are realized by carrying out spatial loading and positioning by virtue of a wheeltrack and combining a hydraulic control loading technology with a data acquisition technology. The spherical all-dimensional loading device disclosed by the invention is applicable to the spatial all-dimensional loading requirement of all the building structural nodes of different types, no specific auxiliary member is required to be processed according to every node test, and the spherical all-dimensional loading device disclosed by the invention can be reused for a long time.

Description

technical field [0001] The present invention relates to a spherical all-round loading device for building structural joint tests, more specifically, to a device for carrying out spatial omni-directional loading on test pieces, automatic adjustment of loading orientation, and automatic data collection in structural joint tests. Spherical reaction frame and supporting devices. Background technique [0002] With the development of building structure technology, more and more innovative structural systems have been applied in practical structural engineering, and the corresponding building structure node forms have become more spatially diverse. For such structures, the safety degree of nodes is often the key to ensure the safety degree of the overall structure, because the destruction of nodes often directly leads to the destruction of the entire structure. [0003] Usually, the analysis of the strength of structural joints needs to be verified by the test data of full-scale o...
