Concrete multi-point toughness testing device for constructional engineering

Abstract

The invention discloses a concrete multi-point toughness test device for constructional engineering, which comprises a device fixing frame, a clamping plate, a cleaning plate, a polishing disc and a toughness test roller, a supporting column is welded and fixed on the device fixing frame, a fixing frame is welded and fixed at the top end of the supporting column, and a bracket is slidably connected in the fixing frame and the supporting column in a limiting manner. A connecting plate is welded and fixed to the bottom end of the bracket, a dragging line is connected to the connecting plate in a bolting mode, the dragging line is wound on a fixed coil, and the fixed coil is welded and fixed to the one-way threaded rod. The concrete multi-point toughness testing device for constructional engineering is provided with a polishing disc, fixing plates on the two sides can drive a circular gear to perform outward meshing rotation on a gear tooth plate while moving outwards, and at the moment, the polishing disc can be driven by a fixing shaft to perform automatic polishing and flattening work on a to-be-detected part of concrete; and therefore, the stability and convenience of subsequent test work can be ensured, and the use diversity of the device is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a concrete multi-point toughness test device for building engineering. Background technique [0002] Cement concrete is one of the most important building materials in the world today. Although the use of this material has a long history, in recent decades, there have been great changes in both material performance and construction technology. At the same time, due to the improvement of modern technology's performance requirements for concrete, the complexity brought about by the increase of concrete components, and the modernization of construction technology, it has gradually developed into a systematic science and technology. Therefore, in order to further improve the performance of concrete The use performance needs to be combined with the use of the toughness test device to test the toughness of concrete to ensure the stability of the follow-up research work. ...
