Bridge reinforcing device, bridge reinforcing method and obtained bridge
The invention discloses a bridge reinforcing device, a bridge reinforcing method and an obtained bridge. The bridge reinforcing device comprises a mechanical anchoring part and a carbon fiber plate. The mechanical anchoring part is composed of a bottom layer steel plate, a top layer steel plate, connecting bolts and matched pre-tightening nuts. The bottom layer steel plate and the top layer steelplate are parallel to each other, and a gap is reserved between the bottom layer steel plate and the top layer steel plate; the carbon fiber plate sequentially penetrates through the gap and is bondedwith the bottom layer steel plate and the top layer steel plate; and one end of each connecting bolt is connected with the bottom layer steel plate in a welded mode, the other end of each connectingbolt penetrates through a bolt hole reserved in the top layer steel plate, and a side surface of the carbon fiber plate is pre-tightened through the pre-tightening nuts. The bottom layer steel plate is smaller than the top layer steel plate in size in a length direction, two beam body chemical bolt penetrating holes are further reserved in the top layer steel plate, and the holes are matched withchemical bolts implanted in a beam to be reinforced in advance.
本发明公开了一种桥梁加固装置、桥梁加固方法及获得的桥梁，包括机械锚固件和碳纤维板，所述的机械锚固件由底层钢板和顶层钢板、连接螺栓和配套预紧螺母组成，所述的底层钢板和顶层钢板相互平行，两者之间留有间隙；所述的碳纤维板依次穿过所述间隙，且与底层钢板和顶层钢板粘结在一起；连接螺栓的一端与底层钢板采用焊接方式进行连接，另外一端穿过顶层钢板预留的螺栓孔，通过预紧螺母对碳纤维板的侧面进行预紧；所述底层钢板较顶层钢板长度方向尺寸较小，在所述的顶层钢板还预留有2个梁体化学螺栓穿过孔，该孔与预先植入在待加固梁上化学螺栓配合。
