Accompanying drawing explanation
Be specifically described below in conjunction with the damping device of accompanying drawing to building described in the utility model.
Fig. 1 is the structural representation of the utility model damping device;
Fig. 2 is the structural representation of the damping device of the utility model socket damping spring.
As shown in the figure, building bottom 1, ground 2, damping spring 3, damping helmet 4, top braces seat 5, quadrangle base 6, arc surface 7.
Detailed description of the invention
As shown in Figure 1, the damping device of building described in the utility model, is provided with multiple, is fixed between building bottom 1 and ground 2, and each damping device interval is arranged, and is uniformly distributed.
As shown in Figure 1, damping device comprises damping spring 3, damping helmet 4 and top braces seat 5.One end of damping spring 3 is fixed on ground 2, and the other end is provided with damping helmet 4, and damping spring 3 is in half compressive state.Top braces seat 5 is arranged on building bottom 1, and matches with damping helmet 4 and arrange, and thus damping helmet 4 is between damping spring 3 and top braces seat 5.Damping helmet 4 is hemisphere shape, and top braces seat 5 is the arc surface 7 caved in building bottom 1 with the contact surface of damping helmet 4, and arc surface 7 and damping helmet 4 match.Arc surface between damping helmet 4 with top braces seat 5 contacts, and damping spring 3 and damping helmet 4 can be made to swing in all directions, play the effect of antidetonation.Further, the return characteristic of damping spring 3, serves the effect of buffering, absorbs the energy of seismic wave, reaches the object of antidetonation.
Because structural quality is huge, this hot coiling spring using novel damping spring 3 to adopt wire diameter larger, preferably adopts the hot coiling spring of wire diameter 100-200mm.Hot coiling spring has another name called large spring, is applied to national defence, ocean, space flight, railway, nuclear power, wind-powered electricity generation, thermoelectricity, engineering machinery, mining machinery, building machinery, elevator etc.The material of hot coiling spring can be 60Si2MnA, 50CrVA, 4Cr13,60Si2CrA.
Preferably, the load-carrying ability of hot coiling spring is 5000-10000N.External diameter and the length of hot coiling spring can be selected according to the area of the quality of building and building bottom 1.Preferably, external diameter is adopted to be the hot coiling spring of 1-2m.When ratio between structural quality and building bottom 1 area is larger, external diameter can be adopted comparatively large, the hot coiling spring that load-carrying ability is larger; When ratio between structural quality and building bottom 1 area is less, external diameter can be adopted less, the hot coiling spring that load-carrying ability is less.After building completes, should ensure that hot coiling spring does not reach its peak load ability, namely hot coiling spring is in half compressive state.In order to ensure the normal duty of hot coiling spring, preventing hot coiling spring stressed excessive and compacted, can multiple hot coiling spring is arranged between ground 2 and building bottom 1 uniformly at intervals, by spaced apart to ground 2 and building bottom 1.When seismic wave is upwards transmitted by ground 2, after damping device absorbs, alleviate the energy of seismic wave, the less vibration of building.
Top braces seat 5 comprises a quadrangle base 6, the one side that quadrangle base 6 contacts with damping helmet 4 is arc surface 7, arc surface 7 caves in building bottom, and match with damping helmet 4, damping helmet 4 wraps up by such arc surface 7, and damping helmet 4 is rotated along arc surface 7, damping spring 3 can in any direction on wave, better buffering seismic wave energy, reduces the destruction to building.
As shown in Figure 1, the curvature of top braces seat arc surface 7 is less than the curvature of damping helmet 4, ensure that the degree of crook of top braces seat arc surface 7 is less than the degree of crook of damping helmet 4, and damping helmet 4 is rotated along the arc surface 7 of top braces seat.The chord length of top braces seat arc surface 7 correspondence is at least the twice of damping helmet 4 diameter, and the radius of arc surface 7 is greater than the radius of damping helmet 4, make arc surface 7 better parcel damping helmet 4, so that damping helmet 4 freely rotates along top braces seat arc surface 7.Be point cantact between damping helmet 4 and top braces seat 5, such damping helmet 4 can wave in all directions along the arc surface 7 of top braces seat, isolates the shear wave of earthquake, compressional wave, absorbs, and reduces the vibration arriving building.
Fixed form between damping spring 3 with damping helmet 4 can be connected or by being welded to connect by gluing together, connect with welding as example in the present embodiment, be welded to connect and both firmly, stably can be fixed together, along with earthquake is rocked together, absorb the energy of earthquake together.
As shown in Figure 2, can also be socketed with the second damping spring in damping spring 3, the active force superposition of such damping spring 3, improves the elastic force of damping spring, better absorbs seismic energy, and buffering seismic wave, avoids the heavy damage of building.The diameter of inner damping spring is less than the diameter of outside damping spring, is convenient to the damping spring of inside be put into outside damping spring.The active force superposition of multiple damping spring connected together, improves elastic force, and enhances return characteristic.
Outside damping spring can be identical with the spiral rotating direction of inner damping spring, also can be contrary.But be contrary with the spiral rotating direction of inner damping spring for the damping spring of outside in the present embodiment.When external vibration-absorbing spring is contrary with the spiral rotating direction of inner cushion spring, damping spring is under the effect of seismic wave, not only horizontal motion but also the motion of vertical direction can occur, motion in the horizontal direction, make spring double swerve, the external vibration-absorbing spring active force cross action that make external vibration-absorbing spring and inner cushion spring contrary to the spiral rotating direction of inner cushion spring, damping spring is vacillated now to the left, now to the right within the specific limits, is returned to initial position.Further, when shrinking after damping spring is due to the effect extension of seismic wave, if spiral rotating direction is contrary, the probability that damping spring is intertwined is decreased.
The damping device of building described in the utility model, utilizes the return characteristic of damping spring 3, absorbs the energy of seismic wave.Damping helmet 4 is provided with at the top of damping spring 3, the top braces seat 5 with the arc surface matched with damping helmet 4 is set in building bottom 1, damping helmet 4 is rotated along arc surface 7, and damping helmet 4 and arc surface 7 are point cantact, damping helmet 4 can wave in any direction along arc surface 7, absorb seismic wave energy, reduce the seismic energy being delivered to building, avoid the badly damaged of building.
The above is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any technician being familiar with this patent is not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned prompting can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of the utility model scheme.
