Compared with the prior art, the utility model has the advantages of: the static loading device specially for the bridge model has a simple structure and low cost; in addition, by setting the guide rails on both sides of the base, the guide rails are set on the support and the pillars. The multi-point measurement of the mechanical properties of the test sample is realized; the pillar adopts the outer rod and the inner rod to realize the lifting of the loading device through the bolt; by setting the displacement gauge on the movable support plate and the The pressure sensor is set to realize the measurement of the deflection value and the force value; the transmission of the simple worm gear is used to realize the force loading; the disadvantage of this utility model is that it cannot carry out multi-angle pressurization experiments on the experimental bridge deck

Abstract

The invention relates to a model experiment device, in particular to a bridge combination unit space model experimental device which comprises a device support, a driving motor I, supporting mechanisms I, supporting mechanisms II, an angle support, a pressurizing mechanism and an experimental bridge. A plurality of supporting mechanisms I and a plurality of supporting mechanisms II can be combinedinto different clamping modes to clamp a bridge unit, and different requirements for supporting the bridge unit in an experiment are met; the angle support is driven by the driving motor I to slide on the device support, the pressurizing position of the pressurizing mechanism is adjusted, the pressurizing mechanism is driven by the driving motor II arranged on the pressurizing mechanism to slideon the angle support, and the pressurizing angle of the pressurizing mechanism is adjusted. The experimental bridge is spliced in a shell and beam combination mode, and the number of units is greatlyreduced while the simulation accuracy is guaranteed; and the calculation cost and the convergence difficulty of nonlinear finite element analysis of the concrete box girder are greatly reduced.

Description

technical field [0001] The invention relates to a model experiment device, in particular to a bridge composite unit space model experiment device. Background technique [0002] For example, the publication number CN203275108U is a bridge model static loading device, which includes a base, and the base is provided with at least two supports for placing test samples, and a loading device is also provided in the vertical direction of the base. Compared with the prior art, the utility model has the advantages of: the static loading device specially for the bridge model has a simple structure and low cost; in addition, by setting the guide rails on both sides of the base, the guide rails are set on the support and the pillars. The multi-point measurement of the mechanical properties of the test sample is realized; the pillar adopts the outer rod and the inner rod to realize the lifting of the loading device through the bolt; by setting the displacement gauge on the movable suppor...
