Abstract
The invention discloses a three-directional shearing model box device. The device comprises a steel plate and multiple framework layers mounted above the steel plate. The framework layers comprise multiple layers of frameworks, rubber dies arranged on the inner sides of the frameworks in a riveting manner, supporting units mounted between the framework layers, and columns mounted on the periphery of the steel plate. The frameworks are made of light aluminum alloy materials. The frameworks are parallelly arranged at equal vertical intervals. The columns are arranged on the periphery of a shearing model box at equal intervals, so that the shearing model box can freely move in three directions when inputting three-directional seismic excitation, and ultra-displacement, jumping and shedding phenomena during a test of the shearing model box can be avoided. The frameworks are made of aluminum alloy H-section steel, so that the weight of the shearing model box is reduced, and the influence on the whole model by the framework weight can be reduced. The aluminum alloy H-section steel frameworks have enough rigidity, so that the model soil is zero in lateral strain in the horizontal direction, and the aluminum alloy H-section steel frameworks can maintain original states after the seismic motion excitation.

Embodiment
As Figure 1-3, a kind of three-dimensional shear model box device described in the embodiment of the present invention, comprising: steel plate, multiple ccf layer, and it is arranged on described steel plate 1 top; Described ccf layer comprises: multistory frame 3, rubber pattern 5, and its rivet clasp is inside described framework 3; Support member 2, it is arranged on column 4 between described framework 3 layers, and it is arranged on described steel plate 1 periphery; Described each framework 3 is the arrangement of vertical equidistant parallel, and described framework 3 is the aluminium alloy H profile steel of round sealed, and described support member 2 top is identical with substructure, and the distribution of described support member 2 and described column 4 is equidistant arrangement.In described shear model casing, steel plate 1 should have enough bearing capacities, to ensure the security in hoisting process, framework 3 is aluminium alloy H profile steel, argon arc welding is adopted to become a closed annulus between aluminium alloy H profile steel, make the height of its web should be consistent with the portion size of support member 2, so that framework 3 can form effective constraint to the soil body of inner splendid attire, framework 3 is connected by support member 2 between layers, the lower part of support member 2 is connected with tangential (radial direction) of framework 3, the upper part of support member 2 is connected with the radial direction (tangentially) of framework 3, the part up and down of support member 2 can move freely, the orthogonal horizontal direction of multilayer (radial and tangential) and a vertical motion can be met when shear model casing can be made like this to input three dimensional earthquake excitation, and ensure can not come off when vibrating, and support member 2 tool has the rich orthogonal level of multilayer displacement upwards and vertical bearing capacity, to meet horizontal direction motion and the vertical motion of shear model casing, column 4 can ensure that shear model box can not produce excessive horizontal shift or topple in vibration processes for round steel pipe, rubber pattern 5 is that common rubber pattern not only can stop that the soil body leaks outside, and can play the effect of reduction " boundary effect ".
The column of equidistantly arrangement is installed in shear model box periphery, thus realize shear model box and can move freely in three directions when inputting three dimensional earthquake excitation, and ensure that shear model box does not occur in process of the test that carry moves, take-off and the phenomenon such as to come off.Framework adopts aluminium alloy H profile steel, alleviate the quality of shear model box, the impact of frame mass on block mold can be reduced, aluminium alloy H profile steel frame has enough rigidity simultaneously, make the model soil body be zero lateral strain in the horizontal direction, and aluminium alloy H profile steel frame can keep its original state after earthquake motion excitation.The layer of framework and the aluminium alloy H profile steel of interlayer are provided with support member at upper and lower groove, and (radial and tangential) can be made between layers in the horizontal direction without Frictional Slipping, on vertical, to produce displacement; The inner side of shear model box is provided with rubber membrane, the deficiency in the space occurred between framework can be made up, the effective prevention soil body leaks outside, and can reduce soil body shear stress, shear model box have light rigidity, simple structure, cheap, install and apply feature easily.
Concrete when using: the structure of layer and interlayer is that the aluminium alloy H profile steel framework 3 of annular is formed by stacking from bottom to top, layer is connected with bolt with interlayer and support member 2, the framework 3 of the bottom is with bolts with steel plate 1, and on the edge of steel plate 1, welding equally spaced column 4, rubber pattern 5 rivet clasp is in the inside of every layer of framework 3.When making shear model box, each layer aluminium alloy H profile steel framework 3 level should be made, and ensure that its horizontal direction is mutually vertical.When connecting frame 3 and support member 2, the upper component of support member 2 is made to keep all consistent with the direction of lower member, such as: the lower member of support member 2 is when framework 3 connects, the pad of protrusion is put in its multilayer end, left and right, to limit tangential displacement, and the remaining keyhole of lower member and upper component keyhole are connected with framework 3 and guarantee that bolt will lower than support member 2 associated components, guarantee that support member 2 is free to slide, and before installation support member 2, be coated with moderate lubrication oil, to reduce the friction of support member 2 component.When assembling, guarantee the leakproofness of rubber pattern 5, in order to avoid the soil body enters in aluminium alloy H profile steel framework 3 groove, thus increasing friction force, affect the movement of support member 2, cause the shearing rigidity effectively can not simulating the soil body.When carrying out shaketalle test, steel plate 1 adopts and is bolted on shaking table, can encourage along any direction input seismic wave of shear model box.
