Multifunctional fabricated support for background wall of modular structural mechanics experiment platform

Abstract

The invention provides a multifunctional fabricated support for a background wall of a modular structural mechanics experiment platform. The support comprises a support matched sliding strip, a support matched sliding groove which is connected with the support matched sliding strip through a bolt and used for restraining or releasing linear displacement of the support matched sliding strip in thehorizontal direction and the vertical direction, and any restraining form of a fixed support, a fixed hinge support, an X-direction sliding hinge support, a Y-direction sliding hinge support or a movable hinge support can be provided for the joint; and the support matching part is used for fixing the node, is arranged above the support matching sliding strip and is fixed with the support matchingsliding strip through the bolt. The support is formed by combining all the components, machining is convenient, operation is easy and convenient, precision is high, one set of support component can beconverted into different kinds of constraint models through the adjusting bolts, flexibility is high, and usability is high.

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...
