A multifunctional assembled support for the background wall of a modular structural mechanics experiment platform

Abstract

The present invention provides a multifunctional assembled support for the background wall of a modular structural mechanics experiment platform, comprising: a supporting slide bar for the support, a supporting chute for the support, the supporting chute for the support and the supporting sliding bar for the support are connected by bolts, It is used to constrain or release the horizontal and vertical linear displacement of the supporting slide bar of the support, which can provide fixed support, fixed hinge support, X-direction sliding hinge support, Y-direction sliding hinge support or movable hinge for nodes Any type of restraint in the support; the supporting parts of the support are used to fix the nodes, and the supporting parts of the support are arranged above the supporting slide bars of the support, and are fixed with the supporting slide bars by bolts. The invention is composed of various components, which is convenient to process, easy to operate and high in precision, and a set of support components can be transformed into different types of restraint models by adjusting bolts, with high flexibility and strong usability.

Description

technical field [0001] The invention relates to the field of teaching and scientific research experiment devices for the specialty of civil engineering, in particular to a multifunctional assembled support for the background wall of a modular structural mechanics experiment platform. Background technique [0002] Structural mechanics studies the effects of structures under various load effects, mainly including internal forces, displacements and dynamic responses. As one of the professional mechanics course system, its course is a crucial professional basic course for civil engineering and civil engineering related majors. After long-term accumulation and development, the theoretical system of structural mechanics knowledge has been relatively complete. [0003] Civil engineering is a traditional engineering major. In addition to imparting theoretical knowledge such as structural analysis methods, calculation formulas and various theoretical theorems, the teaching of its pr...
