The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
Embodiment
As shown in Figure 1, the vibration isolating suspension 100 in the embodiment of the present invention is used to the main structure body of the building being located thereon that the function of supporting and vibration isolation is provided, and comprises the first half, friction pendulum support and the latter half.
As depicted in figs. 1 and 2, the first half 101 of vibration isolating suspension 100 comprises the top base 1 and the top pre-embedded steel slab 7 that set gradually from top to bottom.Top base 1 is positioned at the top of vibration isolating suspension 100, is fixed together by multiple upper built-in fittings 2 and top pre-embedded steel slab 7.
Friction pendulum support, between the first half 101 and the latter half, comprises top-surface camber plate 8, lower surface camber plate 9 and the slide block 4 between top-surface camber plate 8 and lower surface camber plate 9.Top-surface camber plate 8 is fixed on top pre-embedded steel slab 7 by high-strength bolt 3.Slide block 4 is seized on both sides by the arms by top-surface camber plate 8 and lower surface camber plate 9.When vibration occurs, slide block 4 slides in the sliding rail that top- surface camber plate 8 and 9 regulations of lower surface camber plate form, and top-surface camber plate 8 is moved with respect to lower surface camber plate 9.Subsequently, under the Action of Gravity Field of top-surface camber plate 8 above structures, top-surface camber plate 8 is reset to again initial position, thereby plays the effect of separating vibration.Friction pendulum support in the present embodiment is known technology, adopts at present conventional on the market friction pendulum support.
As shown in figures 1 and 3, the latter half 102 of vibration isolating suspension 100 comprises the positioning part and the lower base 12 that set gradually.
Positioning part regulates for the position of the lower surface camber plate 9 to friction pendulum support, comprises base plate, low friction plate, a circle convex wall and positioning bolt.
The bottom of base plate is fixedly connected with lower base 12 by multiple lower built-in fittings 5, and these lower built-in fittings 5 are imbedded in lower base 12.Base plate in the present embodiment is preferably square.
Convex wall is limited within the walls round the edge setting of base plate and by low friction plate 6, and the longitudinal section of convex wall and base plate is spill.Because base plate is preferably square, and convex wall is around the edge of base plate, so the shape that convex wall surrounds is also square.Convex wall and base plate are integrally formed during fabrication, are used as bottom positioning pre-embedded steel slab 11.
Positioning bolt 10 has even number, and these positioning bolt 10 mean allocation are on convex wall.The present embodiment is provided with 12 positioning bolts 10.Because what convex wall surrounded is shaped as square, so be all assigned three positioning bolts 10 on every limit of convex wall, the positioning bolt 10 on relative two limits of convex wall is subtend setting.The positioning bolt 10 of two subtend settings is considered as a pair of positioning bolt 10.Every pair of positioning bolt 10 utilizes the counter-force of convex wall to be connected on lower surface camber plate, give the effect of the power of lower surface camber plate 9 balances, like this, multiple positioning bolts 10 can push up the curved slab 9 of admittedly staying from different directions, to prevent that lower surface camber plate 9 from sliding on low friction plate 6, and depart from the initial position of lower surface camber plate 9 at factory setting.Positioning bolt 10 in the present embodiment adopts high-strength bolt.
Instantly, when displacement occurs curved slab 9 after vibration or in work progress, can make lower surface camber plate 9, on low friction plate 6, slippage occur by the spacing that regulates every pair of positioning bolt 10 on convex wall, thereby realize the adjusting of the position to lower surface camber plate 9.Because the friction factor of low friction plate 6 is very little, lower surface camber plate 9 is easy to slide on low friction plate 6, so only need to regulate positioning bolt 10 just can make top-surface camber plate 8 and lower surface camber plate 9 reset, and need not carry out again large-area construction or use the upgrade kits such as jack, therefore not only operation is simple, and time saving and energy saving, have a good application prospect.
Friction pendulum support is arranged on the bottom of building or the below of floor plates conventionally.Because friction pendulum support is in installation and use procedure, the first half and the latter half easily misplace, thus need to reset, to keep the due service behaviour of friction pendulum support.Vibration isolating suspension in the present embodiment not only can make relatively easily friction pendulum support reset after earthquake, and can in building structure construction, conveniently adjust the position of friction pendulum support.In the construction and installation process of vibration isolating suspension, vibration isolating suspension integral installation is in building structure, if there is relative displacement in top-surface camber plate 8 and lower surface camber plate 9, only need regulate with positioning part the position of this friction pendulum support, install and friction pendulum support need not be taken out from vibration isolating suspension to adjust again separately, so convenient and quick construction is time saving and energy saving.
The above-mentioned description to embodiment is can understand and use the present invention for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the invention is not restricted to above-described embodiment, those skilled in the art are according to announcement of the present invention, and not departing from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
