Description of drawings
Fig. 1 is a kind of isolated form tumbling-type of the present invention damping device structural representation.
The specific embodiment
A kind of isolated form tumbling-type damping device, said damping device partly is made up of roll part and rolling disk.
Described roll part by round platform post 2, rubber cushion 3, pressure plare 4, ball-joint seat 5, steel ball 6 and spin 15 from the top down order be installed in the top control cabinet 1 and and top control cabinet 1 inboard gapped block parts when preventing discontinuity equalization; It is dull and stereotyped square that pressure plare 4 is; Its upper and lower surface fixedly mounts nine round platform posts 2 respectively; Pressure plare 4 is mainly used in the separation gel mat thickness, protection rubber cushion and balance support power.
Stick one deck steel ball 6 in the recessed body 16 of hemisphere below the said ball-joint seat 5; Half volume of spin 15 coincide with steel ball 6 and contacts; Produce in spin bottom can constitute under the thrust spin 15 and steel ball 6 each other not shift positions arbitrarily to flexible rotation; The recessed mouthful periphery of hemisphere is uniformly distributed with at least 2 screw holes below the ball-joint seat 5, on the ring-like baffle plate 7 bolt-inserting hole that matches with screw hole is arranged, and bolt 8 is fixedly connected ring-like baffle plate 7 through in the patchhole DRIVE SCREWS hole with ball-joint seat 5.
Said rolling disk part be installed in from bottom to top in the base control cabinet 11 by rubber cushion 3, round platform post 2, rolling disk seat 10, rolling disk 13 and and base control cabinet 11 inboard gapped; Shape is by matching surface that contacts with spin 15 and the recessed body formed with tiltedly facing directly of matching surface smooth transition in the top of said rolling disk 13; Main effect is that rolling disk is shaken wave impact and swings; And promotion spin 15 is rolled with the rolling disk displacement; After the ripple that shakes stopped, the spin nature was from the tiltedly straight domatic mid point original position that rolls into of rolling disk.Rib 9 does not break away from the rolling disk scope when being 15 rollings of control spin.The upper periphery of recessed body is mounted with rib 9, and annular rubber cushion 14 is installed in the medial surface of rib 9, generation elastic resistance when being used for spin and contacting with rib.
The shape mid point docks installation in use in the vertical lower mid point of spin 15 and the top of rolling disk 13; Its interaction is; Rolling disk 13 can promote when swung by seismic shock or during rotary swing spin 15 in dish about or the rotation rolling; And do not produce of the swing of connectivity spin with the upper part, therefore can dissolve the fracture strength that seismic wave directly is transmitted to main body.
Round platform post 2 is installed with nine pits, the 17 corresponding insertions above the rubber cushion 3, and round platform post 2 is all gapped in pit 17 inner rims bottom; It is corresponding vertical with round platform post 2 upper-lower positions of rolling disk part to be installed in the part of rolling, and is mainly used in supported weight, and constitutes clutch property elasticity vigor with rubber cushion 3, increases the effect of antidetonation elasticity and protection rubber cushion.
The bottom fixed installation of control cabinet 1 profile top and base control cabinet 11 profiles is given and is buried reinforcing bar 12 at the top, is respectively applied for to be connected with the main body bottom girder and to be fixedly connected top control cabinet 1 with basic grade beam and to be used for control cabinet inner part globality function.
The position, middle and lower part, four sides of control cabinet 1 profile at the top; Each is installed, and recess is pronely mixed button 24, all there is corresponding through hole on the two sides, the left and right sides of mixing button 24; Cross bar two ends, T-shaped screw rod 20 upper end are inserted respectively and are mixed in button 24 through holes, are mixing the vertical by following position of button 24, and each installs support power spring 23; Support power spring 23 two ends are fixedly connected with T-shaped screw rod 20 relevant positions with top control cabinet 1 respectively; T-shaped screw rod and corresponding component role be, when using the construction of isolated form tumbling-type damping device, is fixedly connected wherein spin device with the rolling disk device and is convenient to construct.In the time need not connecting, can open screw device automatically through the compression weight of building.
Four sides and T-shaped screw rod 20 vertical correspondence positions in base control cabinet 11 profiles; Each install a recess towards around the outside buckle 21; Screw rod 20 lower ends are installed in the buckle 21 and with nut 22 and screw; In the relevant position, vertical top of buckle 21, each installs a support power spring 23, and its two ends are fixedly connected with T-shaped screw rod 20 relevant positions with base control cabinet 11 respectively.
When using the construction of isolated form tumbling-type damping device; The weight of cutting weighing load and each weight bearing area of building of holding according to single single unit system shown in Figure 1; The device of different densities quantity is installed respectively, is made each device hold the same amount that cuts below the ability that weighs less than, when construction and installation; Earlier give base control cabinet 11 bottom surfaces that to bury muscle downward, each design attitude is cast-in-place is connected with collar tie beam fundamentally etc.By shown in Figure 1, related device and 11 integral installations of base control cabinet, and T-shaped screw rod 20; Compress support spring 23,25 lower ends downward vertically and snap in the buckle 21, it is tightly fixing that nut 22 screws in 21 times screw end heads of buckle; Rolling disk 13 centers and spin 15 bottom mid points are joined, and the corresponding balance of control cabinet is vertical up and down, and all top control case top covers are in same level height; Give on the top cover and bury muscle 12 and be connected, and upwards carry out main body construction simultaneously with the cast-in-place slab integral structure of main body bottom girder.
When the building main body reaches constant weight; Be installed in rubber cushion 3 in each damping device, pushed by downward gravity, in peripheral pit 17, bounce back with the interstitial diffusion of round platform post 2; Making up and down, the control cabinet distance furthers; Four sides screw rod 20 lower end nuts 22 separate with buckle 21 downwards, and support spring 23.25 outer support power overhang certain altitude position, bayonet socket 21 outside to the screw rod lower end, and this moment, screw device was opened by integral body automatically.
Earthquake is taking place, when building is vertically run ripple up and down, the basis upwards pushed away by seismic wave moment and on move; The gravity of drawing close between basis and the main body is strengthened suddenly; Rubber cushion 3 receives gravity extruding and reduces thickness, and to peripheral rubber cushion pit 17 in, enlarges and round platform intercolumniation crack jam-packed, increase elastic resistance when making round platform post pressurized and produce elasticity; When thrust on the seismic wave makes progress coherence to main body upthrow formation; Seismic wave again moment fall after rise downwards, at this moment can produce the Gravity Separation decompression of moment between basis and the main body again, at this moment rubber cushion 3 expands rapidly again and produces the elastic reaction that impacts gravity when the reply main body falls.
Swing or scroll when rotatablely moving at occurred level seismic wave building; Rolling disk 13 is swung with the basis by base control cabinet 11 systems; And promotion spin 15 constitutes the shift reverse rolling with rolling disk in rolling disk 13; Spin 15 is to receive rolling disk motion thrust and whirlpool changes, and promotes roll each other whirlpool then do not produce mobile original position of steel ball 6 and spin simultaneously.Therefore rolling disk 13 promotes spin 15 original position rotations only with the seismic wave frequency movement, can't remarkable swing effect take place the above agent structure of related spin, and therefore horizontal seismic wave is effectively dissolved by the rolling function of this device the considerable damage energy that building constitutes.After seismic wave stopped, spin was from the domatic mid point original position that can recover automatically at rolling disk of rolling disk.
