Detailed Description

The present invention will be described in more detail with reference to examples.

As shown in fig. 1 to 3, the novel composite structure high pier of the present embodiment includes a bearing platform 1 and a capping beam 2, which are sequentially arranged from bottom to top, and also includes three vertical pillars 3 arranged between the bearing platform 1 and the capping beam 2, the three vertical pillars 3 are distributed in a regular triangle, and the vertical pillars 3 are rigidly connected to the bearing platform 1 and the capping beam 2; from last two horizontally connecting beam 5 of fixedly connected with down between arbitrary two adjacent vertical pillars 3, be connected with combination anti-seismic device 4 through high strength bolt detachably between two connecting beam 5, combination anti-seismic device 4 includes antidetonation board 42 and fixes the mild steel attenuator 41 at antidetonation board 42 upper and lower both ends, treat all component installation backs again and screw up the high strength bolt, make it keep zero axial pressure than the state, the power consumption ability is more superior, also can change at any time simultaneously, the rate of utilization is improved, be convenient for restore after the quick calamity, mild steel attenuator 41 and antidetonation board 42 both ends all are connected with vertical pillars 3.

Further, the connecting beam 5 is of an I-shaped steel structure, the I-shaped steel structure is in an elastic state under the action of small vibration, and is only slightly damaged or kept in the elastic state under the action of large vibration, so that convenience in construction is guaranteed, and the connection quality of the nodes is controlled.

Furthermore, the mild steel damper 41 is arranged in a T shape, a plurality of rhombic openings 412 are formed in the web 411 of the mild steel damper 41 arranged in the T shape along the length direction, the deformation of limb steel among the openings realizes multi-point yield energy consumption, and the rhombic openings 412 have good hysteretic performance, so that the whole structure has better anti-seismic performance.

Further, the anti-seismic plate 42 is of a corrugated steel plate structure, the upper end and the lower end of the anti-seismic plate 42 are fixedly welded with the web 411 of the T-shaped mild steel damper 41, and the corrugated steel plate has good lateral resistance and is beneficial to improving the lateral resistance of the whole structure.

Further, the vertical pillars 3 include square steel pipes and concrete filled inside the rectangular steel pipes.

In the embodiment, the connecting beam 5 is fixed together with the concrete column filled in the vertical strut 3 through the embedded part of the vertical strut 3, so that the operation is simple, and the construction efficiency is favorably improved.

The working principle of the utility model is as follows:

in the normal use stage, the combined structure of the vertical strut 3, the mild steel damper 41 and the anti-seismic plate 42 and the connecting beam 5 are combined to form a box-shaped section, so that the high pier is ensured to have higher bending rigidity and torsional rigidity;

under the action of wind load or small vibration, the utility model is in an elastic state, and provides additional rigidity for the structure;

under the action of medium or large earthquake, the node generates relative displacement, the combined structure of the soft steel damper 41 and the earthquake-proof plate 42 is driven by the vertical pillar 3 to shear, hysteresis and deform to consume energy, the connecting beam 5 is used as a second earthquake-proof fortifying component to consume energy by relying on a plastic hinge formed at the end part, a large amount of earthquake energy transmitted to the main structure from the ground is absorbed, meanwhile, the rigidity of the whole structure is reduced, the inherent period is prolonged, the earthquake action borne by the main structure is reduced, and therefore the damage to the main structure is avoided or reduced, and the safety of the structure is improved.
