Longitudinally Self-resetting drag-line 7 adopts marmem.Be connected with girder 3 with bent cap 2 respectively.When longitudinally Self-resetting drag-line 7 is through concrete, in concrete, answer pre-buried bellows, longitudinally the maximum recovery strain of Self-resetting drag-line 7 is 5%-15%, maximum recovery stress is not less than 550MPa, the longitudinal Self-resetting drag-line 7 of installation after bridge main body structure construction completes, longitudinally Self-resetting drag-line 7 should be stretched to its 0%-50% maximum strain, under geological process, girder 3 athletic meeting increase longitudinal Self-resetting drag-line 7 one lateral strains of both sides, opposite side strain reduces, can earthquake energy, make the longitudinal permanent set of girder 3 less.After earthquake, the Self-resetting function by longitudinal Self-resetting drag-line 7 is returned to before undamaged state girder 3 longitudinal strains.
According to an example of the present invention, the first internal stop 41 and the second internal stop 42 are steel block.
Further, according to an example of the present invention, the height of each in the first internal stop 41 and the second internal stop 42 (the first internal stop 41 in Fig. 1 or the size of the second internal stop 42 above-below directions) is 300mm-800mm.The thickness of each in the first internal stop 41 and the second internal stop 42 (the first internal stop 41 in Fig. 1 or the size of the second internal stop 42 left and right directions) is 20mm-50mm.The length of each in the first internal stop 41 and the second internal stop 42 (the first internal stop 41 in Fig. 2 or the size of the second internal stop 42 left and right directions, not shown) is not more than the length of bent cap 2.
Further, as shown in Figure 3, according to an example of the present invention, the first internal stop 41 is provided with the groove 411 that extends the base of (lengthwise dimension in Fig. 3) and contiguous the first internal stop 41 along the length direction of the first internal stop 41.The second internal stop 42 is provided with along the groove 421 on the length direction extension of the second internal stop 42 and the base of contiguous the second internal stop 42.The distance on the base of the lower edge of groove 411 and the first internal stop 41 is above-below direction size in 1/15-1/5(Fig. 3 of height of the first internal stop 41).The distance on the base of the lower edge of groove 421 and the second internal stop 42 is the 1/15-1/5 of the height of the second internal stop 42.Thus, under geological process, girder 3 displacements are when excessive, girder 3 can clash into the first internal stop 41 and the second internal stop 42, the first internal stop 41 and the second internal stop 42 bottom slots, can be so that the first internal stop 41 and the second internal stop 42 damage locations be clear and definite, and material is that steel are also comparatively easily changed after seismic Damage.
According to an example of the present invention, the first outer baffle block 51 and the second outer baffle block 52 are concrete block.Advantageously, the height of each in the first outer baffle block 51 and the second outer baffle block 52 (the first outer baffle block 51 in Fig. 1 or the size of the second internal stop 62 above-below directions) is 500mm-1000mm.The thickness of each in the first outer baffle block 51 and the second outer baffle block 52 (the first outer baffle block 51 in Fig. 1 or the size of the second internal stop 62 left and right directions) is 200mm-600mm.The length of each in the first outer baffle block 51 and the second outer baffle block 52 (the first outer baffle block 51 in Fig. 2 or the size of the second internal stop 62 left and right directions) is not more than the length of bent cap 2.Under geological process, the first internal stop 41 and the second internal stop 42 destroy, and girder 3, along with the increase of displacement, can clash into the first outer baffle block 51 and the second outer baffle block 52, thereby can effectively prevent that girder 3 from producing the beam that laterally falls and destroying.
According to an example of the present invention, the spacing between the first internal stop 41 and the first outer baffle block 51 is greater than the height of the first outer baffle block 51.Spacing between the second internal stop 42 and the second outer baffle block 52 is greater than the height of the second outer baffle block 52.
According to an example of the present invention, in girder 3, be also provided with granule damper 9.
Advantageously, according to an example of the present invention, granule damper 9 comprises the damping particles container 91 being located in girder 3 and is arranged in the damping particles 92 in damping particles container 91.
Further, according to an example of the present invention, damping particles 92 is selected from least one in steel ball, bead, lead sweat, concrete ball, ceramsite sand.The particle diameter of damping particles 92 is 2mm-100mm.The stacks as high of damping particles 92 in damping particles container 91 is the 1/15-1/5 of the height of damping particles container 91.
