Detailed description of the invention
Below in conjunction with embodiment, the invention will be described in further detail.
Embodiment 1: as Figure 1-5, a kind of Base-isolation system for the electric fixtures that interconnects of invention of this example, is provided with electric fixtures support 1 below described electric fixtures 2; Described system comprise connect successively for placing the cushion cap 5 of described electric fixtures support 1, earthquake isolating equipment 6 and basic case 4; The sidewall of the surrounding of described basic case 4 being provided with the stopping means 7 for limiting described cushion cap 5 position, being used for bottom described basic case 4 earthquake isolating equipment 6 is installed.
Described earthquake isolating equipment 6 is rubber damping isolator 6.Described earthquake isolating equipment 6 comprises top flange plate 9, rubber cover 13 and bottom wing listrium 10; The steel plate 12 being provided with laminated rubber 11 in described rubber cover 13 and being arranged in described laminated rubber 11.
Vertical average compressive stress value when the type selecting of earthquake isolating equipment 6 is mainly considered its maximum horizontal displacement under rarely occurred earthquake effect and uses, determines the performance parameter of bearing usually according to both.Again further according to the requirement of design parameters, determine other performance requirements such as the horizontal rigidity of this kind of model bearing, equivalent viscous damping ratio.Earthquake isolating equipment 6 is arranged and will, according to superstructure Mass Distribution and plane force-bearing situation, be made every effort to symmetrically, and the center of rigidity of Seismic Isolation of Isolation Layer be made to overlap with superstructure mass centre as far as possible.Limit spring device should have the compression stroke of 150mm at least, and the setting height(from bottom) of limit spring device should be consistent with the height center of cushion cap.Bottom the case 4 of basis, foundation soil should have enough bearing capacity and ensures that electric fixtures 2 normally runs.Drainage measure should be carried out bottom the case 4 of basis, to ensure that when precipitation water flow energy is discharged rapidly in time, bottom basic case, gutter is set along its surrounding, the size of main drain should be not less than 200mm × 300mm × 150mm (bottom width × suitable for reading wide × high), in gutter, a collecting well is set every 1m, so that ponding is got rid of in time, all collecting wells converge to a gutter and receive transformer station's inner water drainage system.。
Described basic case 4 surrounding sidewall thickness should not be less than 100mm, and bottom thickness should not be less than 200mm.Horizontal range t between described cushion cap 5 edge and limit spring device should be not less than 500mm.Described electric fixtures support 1 is by the bearing settlement bottom it on described cushion cap 5, and described support bearing 8 outward flange distance cushion cap 5 outer ledge should not be less than 500mm.For ensureing that cushion cap 5 should have enough rigidity, its thickness should not be less than 500mm.
Under geological process, earthquake isolating equipment can effectively reduce seismic energy to superstructure transmission; simultaneously limit spring device not only plays protection earthquake isolating equipment and is unlikely to produce excessive horizontal movement under large shake effect and the function destroyed, and can also play the effect of buffering seismic forces and dissipation seismic energy.Under geological process, this shock isolation system different parts collaborative work is to reach the object reducing seismic forces transmission and dissipation seismic energy, improves the anti-seismic performance of electric fixtures.
The operating principle of this system is discussed below: arrange earthquake isolating equipment 6 bottom cushion cap form Seismic Isolation of Isolation Layer by supporting at interconnective electric fixtures support 2, electric fixtures 1 and basic case 4 are separated, utilize earthquake isolating equipment to isolate or dissipation seismic energy to avoid or to reduce seismic energy to top structural transmission, reduce the earthquake response of electric fixtures 1.This Seismic Isolation of Isolation Layer has the isolating affection of two aspects, earthquake isolating equipment has blocked part earthquake energy transferring to described electric fixtures support 1 and above apparatus on the one hand, the forms of motion of electric fixtures 1 under geological process on cushion cap top is a mass motion substantially on the other hand, substantially reduces the coupling effect of earthquake of interconnect equipment.When geological process is larger; for preventing earthquake isolating equipment 6 from producing excessive horizontal distortion and destroying; at basic case 4 surrounding sidewall, limit spring device is set; when the cushion cap 5 supported by earthquake isolating equipment 6 is when geological process bottom offset is excessive; cushion cap 5 comes in contact with the limit spring device of basic case 4 surrounding sidewall; also can dissipate while the displacement of constraint cushion cap 5 after spring is compressed and partly shake energy, protect the safety of electric fixtures 1 under geological process from another point of view.
Construction and the installation steps of this system are as follows: (1) carries out the prefabricated work of equipment supporting cushion cap 5.(2) carry out foundation dredging, carry out the construction working of basic case 4.(3) according to design drawing require earthquake isolating equipment 6 is installed bottom basic case 4, at right angle setting limit spring device on basic case 4 sidewall.(4) prefabricated supporting cushion cap 5 is connected with earthquake isolating equipment 6 top.(5) installation work of cushion cap 5 top electric fixtures is carried out.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; although those of ordinary skill in the field are to be understood that with reference to above-described embodiment: still can modify to the specific embodiment of the present invention or equivalent replacement; these do not depart from any amendment of spirit and scope of the invention or equivalent replacement, are all applying within the claims of the present invention awaited the reply.
