Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Figure 2 and Figure 3, large scale high stability target chamber earthquake protection radial support apparatus described in the utility model, for supporting target chamber 1, comprise multiple supporting component, the horizontal center line of multiple described supporting component be located in the same horizontal plane and this horizontal plane between the top and bottom of target chamber 1, multiple described supporting components are uniformly distributed in the surrounding of target chamber 1, described supporting component comprises support and connection block 8, upper steel plate 2, middle steel plate 3, lower steel plate 6 and the pre-embedded steel slab 5 be embedded in advance in the basis 4 of target chamber 1, one end and the target chamber 1 of support and connection block 8 are welded to connect, the upper and lower of the other end of support and connection block 8 is connected with one end of the upper steel plate 2 of transverse direction and one end of horizontal lower steel plate 6 respectively, one end of horizontal middle steel plate 3 to be placed between the other end of upper steel plate 2 and the other end of lower steel plate 6 and to be connected by vertical pretension bolt 7, the other end of middle steel plate 3 is fixedly connected with pre-embedded steel slab 5 by the stud be welded on pre-embedded steel slab 5.
As shown in Figure 3, upper steel plate 2 and lower steel plate 6 go to upper and lower symmetrical structure with the horizontal center line of middle steel plate 3, upper steel plate 2 and lower steel plate 6 are " L " shape, the vertical plate of upper steel plate 2 with between support and connection block 8, the vertical plate of lower steel plate 6 is all connected by horizontal pretension bolt 7 with between support and connection block 8; Upper steel plate 2, middle steel plate 3 and lower steel plate 6 are Q235 steel plate, the surface of upper steel plate 2, middle steel plate 3 and lower steel plate 6 should smooth, zero defect loss, and strict guarantee thickness deviation, the upper surface of the soffit of upper steel plate 2, two surfaces and the lower steel plate 6 up and down of middle steel plate 3 all scribbles aqueous inorganic zinc-enriched coating (not visible in figure).
As shown in Figure 2, the horizontal width of one end middle steel plate 6 is connected with pre-embedded steel slab 5 wider than the one end be connected with upper steel plate 2 horizontal width thus that middle steel plate 6 is formed is trapezoidal.
As shown in Figure 1, Figure 2 and Figure 3, during application, upper steel plate 2, should contact closely between middle steel plate 3 and lower steel plate 6, friction evenly, stable performance.Under normal circumstances, each supporting component is enough to support target chamber 1 to the pressure of each radial direction of its surrounding in experimentation, under the state making target chamber 1 be in micron dimension stability, guarantees that experiment is carried out smoothly; When target chamber 1 bears horizontal space load, support and connection block 8 promotes the Relative sliding that micro/nano level occurs upper steel plate 2 middle steel plate 3 relative to lower steel plate 6, the shortcoming crossing location that cross binding is brought can be made up, thus Planar Mechanisms can not be produced to target chamber 1, avoid the subsidiary stress that target chamber 1 therefore produces.In particular cases, when such as there is earthquake, powerful destructive power makes support and connection block 8 promote upper steel plate 2 middle steel plate 3 relative to lower steel plate 6 larger slippage occurs, multiple pretension bolt 7 is cut off simultaneously, make this bracing or strutting arrangement to the reaction force pop-off of target chamber 1, for target chamber 1 provides security protection, ensure that catastrophic destruction does not occur target chamber 1, thus avoid irremediable loss.
Radial support apparatus described in the utility model is used for the support of the target chamber 1 internal diameter being less than to 10 meters, in this case, as depicted in figs. 1 and 2, the plane at the horizontal center line place of eight symmetrical supporting components is positioned at the below of the horizontal center line place horizontal plane of target chamber 1, in this example, because target chamber 1 is spheroid, so the plane at the horizontal center line place of multiple supporting component is positioned at the below of the equatorial plane of target chamber 1.Composition graphs 1 and Fig. 2, if the internal diameter of target chamber 1 is more than or equal to 10 meters, then can adopt more supporting component, and two groups that are divided into quantity identical these supporting components, two groups of supporting components are upper and lower symmetrical structure with the horizontal center line place horizontal plane of target chamber 1 and equatorial plane, and the quantity of each group supporting component can be 4-8.So just can realize the support force larger to target chamber 1.
Above-described embodiment is preferred embodiment of the present utility model, is not the restriction to technical solutions of the utility model, and such as: also can be asymmetric between upper steel plate 2 and lower steel plate 6, just the uniformity of its power transmission be less better; Upper steel plate 2 and lower steel plate 6 also can not be " L " shape, are just not easy to be connected with support and connection block 8; Support and connection block 8 and middle steel plate 3 also can not be the "T"-shaped structure shown in Fig. 3, as long as symmetrical structure be convenient to be connected with target chamber 1 and pre-embedded steel slab 5 respectively; Middle steel plate 6 also can be rectangle instead of trapezoidal, and just intensity is slightly poor; As long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
