As shown in figures 1-8, a kind of working principle of novel damping Self-resetting energy consumption drag-line support device is as follows: pulley 1 is solid It is scheduled on pedestal 8, several circular holes 3 is set on pedestal 8, are fixed by bolt and main structure body.Prestressing force resets muscle 4 using tool Have a material of high-tensile and low elastic modulus feature, one end is anchored in one end slider box 7 by anchorage 5, the other end around After crossing pulley 1, prestressing force is established using post stretching, is connect by anchorage 5 with other end slider box 7.Wherein prestressing force resets muscle 4 Using connection sleeve 2 at pulley 1, limit plate 6 is used to limit slippage frame 7 to intermediary movements, and limit plate 6 is fixed by welding in On pedestal 8, the rigidity that several pieces of ribbed stiffeners 9 reinforce limit plate 6 is set.By bolt, by the second sliding panel 16, the 4th sliding panel 18, reset energy consumption friction plate 11, reset energy consumption billet 12 are connected with connecting plate 13, and connecting plate 13 is connected with pedestal 8, and the 5th is sliding Movable plate 19, limiter energy consumption friction plate 22 are connected with limiter energy consumption billet 14.By screwing bolts, respectively in the second sliding panel 14, it is established between the 5th sliding panel 19 and limiter energy consumption friction plate 22 between the 4th sliding panel 16 and reset energy consumption friction plate 11 Precompression.One end of strand spiral rope 10 is anchored by anchorage 5 and limiter energy consumption billet 14, and the other end and main structure body structure connect It connects.
As shown in figure 9, a kind of course of work of novel damping Self-resetting energy consumption drag-line support device in building structure is such as Under: whole device is arranged in parallel on architecture beam, the installation pulley guidance on the Vierendeel girder close to bean column node position Strand spiral rope trend, cross-connects to two lateral roofs of building structure.Under the action of illustrating direction load F (solid line indicate by Power cable wire, dotted line indicate non-stress cable wire), stress drag-line is stretched, and drives reset energy consuming mechanism and limiter energy consuming mechanism successive Work.
The utility model is increased by twice by the length that prestressing force can be resetted muscle by setting pulley blocks, to work as prestressing force When resetting the deformation of muscle generation equal length, strain rate is reduced to be not provided with one third when pulley.It so on the one hand can be with The deformability of Self-resetting is improved twice;On the other hand wanting for the elastic extension of prestressing force reset muscle material can also be reduced It asks, to further widen the range of choice of material.Limit plate is used to limit prestressing force and resets the end of muscle to intermediary movements, Second sliding panel, the 4th sliding panel open up a certain number of slots on the 5th sliding panel, can occur along slot length direction Sliding passes through the seismic energy of the second sliding panel and the 4th sliding panel and the sliding friction dissipation input for resetting energy consumption friction plate. Limiter energy consuming mechanism checks axial force of the supports growth by the opposite sliding of the 5th sliding panel and limiter energy consumption friction plate, and protection is led Body structure and the seismic energy that further dissipates.
Under the conditions of small shake, the pulling force of strand spiral rope is not enough to overcome the frictional force and answer in advance for resetting that energy consumption friction plate provides Power resets the sum of the pretension of muscle, therefore one end that strand spiral rope is connected with slider box is equivalent to fixing end.Under the conditions of this, only There is strand spiral rope to play supporting role.
In-big shake under the conditions of, the pulling force of strand spiral rope overcomes the frictional force and prestressing force for resetting that energy consumption friction plate provides The sum of the pretension of muscle is resetted, therefore strand spiral rope pulls on slider box movement.At this moment strand spiral rope and prestressing force reset muscle are The overall stiffness of series relationship, Self-resetting energy consumption drag-line support is remarkably decreased relative to the rigidity of strand spiral rope, to inhibit ground The rapid growth of brisance, to realize the protective effect to main structure.At the same time, slider box and reset energy consumption friction are utilized Opposite sliding dissipation seismic energy between plate.After earthquake, the pulling force that prestressing force resets muscle is consistently greater than maximum static friction force, because This pulls slider box to move to initial position, until contact limit plate is static, realizes runback bit function.
By be more than fortification intensity seismic condition under, strand spiral rope pulling force further increase until make the 5th sliding panel with Limiter consumes energy, and friction plate generation is opposite to be slided.Limiter energy consuming mechanism is started to work at this time, checks axial force of the supports increase, while into one Dissipation seismic energy is walked, main structure is protected.
