As shown in fig. 1 and 2, a mounting structure of a bridge tension and compression support comprises a support body 1. The bridge comprises a cover beam 2 arranged on the upper side of a pier and a cross beam 3 arranged on the lower side of a bridge floor, wherein the cross beam 3 is erected on the upper side of the cover beam 2. Support body 1 sets up along 2 upper surfaces of bent cap equidistant, and the laminating of 3 bottom surfaces of crossbeam and 1 upper surfaces of support body, support body 1 include rubber support 11 and two support steel sheets 12, and two support steel sheets 12 set up along the upper surface and the lower surface of rubber support 11 respectively. And a support cushion 21 is fixedly arranged on the side surface of the cover beam 2 attached to the support body 1, and the width of the support cushion 21 is smaller than that of the cross beam 3. The center department of support base stone 21 upper surface has buried embedded steel sheet 4 underground, has also buried embedded steel sheet 4 in the side of crossbeam 3 with the laminating of support body 1. The support steel plate 12 on the lower side of the support body 1 is fixedly connected with the embedded steel plate 4 on the support base stone 21, and the support steel plate 12 on the upper side of the support body 1 is fixedly connected with the embedded steel plate 4 on the bottom surface of the cross beam 3. Because the width of the seat cushion 21 is smaller than the width of the cross beam 3, the distance between the upper surface of the lid beam 2 and the lower surface of the cross beam 3 is larger, leaving enough clearance to facilitate the subsequent maintenance of the seat body 1 and the replacement of the seat body 1.

As shown in fig. 2 and 3, three anchoring bars 5 are welded on one side of the embedded steel plate 4 away from the support steel plate 12, each anchoring bar 5 comprises a transverse bar 51, and the transverse bar 51 is parallel to one side of the embedded steel plate 4 away from the support steel plate 12 and is perpendicular to the cross beam 3. Both ends of the transverse steel bar 51 are bent towards one side far away from the embedded steel plate 4 to form vertical steel bars 52, and the vertical steel bars 52 are perpendicular to the embedded steel plate 4. The ends of the vertical bars 52 at the two ends of the transverse bar 51, which are far away from the transverse bar 51, are bent towards the other vertical bar 52 to form anchoring claws 53, and the anchoring claws 53 are parallel to the transverse bar 51. The planes of the three anchoring steel bars 5 are parallel to each other, and the distance between two adjacent anchoring steel bars 5 is equal. The anchor reinforcing steel bars 5 connected with the embedded steel plates 4 on the support base cushion stones 21 are embedded in the support base cushion stones 21 and the cover beams 2, and the anchor reinforcing steel bars 5 connected with the embedded steel plates 4 on the cross beams 3 are embedded in the cross beams 3.

As shown in fig. 2 and 3, a compression-resistant net 6 parallel to the upper surface of the support cushion 21 is embedded in the support cushion 21, and the compression-resistant net 6 is adjacent to the embedded steel plate 4 on the upper surface of the support cushion 21. The anti-pressure net 6 is composed of a set of upper steel bars 61 arranged at equal intervals and a set of lower steel bars 62 arranged at equal intervals, the plane where the upper steel bars 61 are located and the plane where the lower steel bars 62 are located are parallel to the upper surface of the supporting cushion, the upper steel bars 61 are perpendicular to the lower steel bars 62, and the lower steel bars 62 are welded on the upper steel bars 61. The two ends of the upper steel bar 61 are both bent downwards to form anchoring barbs 63, the anchoring barbs 63 are U-shaped, and the openings of the anchoring barbs 63 at the two ends of the upper steel bar 61 are both towards the middle point of the upper steel bar 61.

After installing support body 1, support body 1 and pre-buried steel sheet 4 welding are in the same place, and is effectual fix support body 1 between bent cap 2 and crossbeam 3. When the bridge body bears large external load, the rubber support 11 in the support body 1 deforms, so that the force acting on the upper structure is well borne, and the force is stably transmitted to the cover beam 2. The whole support body 1 is more stable to mount and is not easy to generate the phenomenon of dislocation. The anchoring steel bars 5 embedded in the cover beam 2 and the cross beam 3 are tightly connected, and the compression-resistant net 6 embedded in the support cushion stone 21 can uniformly disperse the force transmitted to the support cushion stone 21, so that the whole support cushion stone 21 is firmer and not easy to damage.
