Transverse widening structure of prestressed concrete continuous box girder bridge
The invention discloses a prestressed concrete continuous box girder bridge transverse widening structure which comprises a base, a transverse buffering mechanism is arranged on the inner side of the base, the transverse buffering mechanism comprises three prestressed sleeves, and the three prestressed sleeves are all fixedly arranged in the transverse buffering mechanism; prestressed tendons are arranged in the centers of the inner sides of the three prestressed casing pipes, and hollow sliding sleeves are arranged on the outer sides of the two ends of the prestressed tendons. The arc-shaped limiting clamp is inserted into the inner side of one end of the mounting base, the fastening bolt is used for fixing the arc-shaped limiting clamp; at the moment, the arc-shaped limiting clamp is matched with the trapezoidal guide rail to conduct limiting treatment on the sliding clamping base. During dismounting, the arc-shaped limiting clamp is taken out from one end of the mounting base, and then the sliding clamping base can be taken out from the trapezoidal guide rail in a sliding mode. According to the invention, the widening structure is of an assembled structural design and is convenient to mount and dismount, and after the widening structure is connected with the two steel box girders, the two steel box girders can be subjected to transverse and longitudinal damping treatment, so that the structure is multifunctional.
本发明公开了一种预应力混凝土连续箱梁桥横向拼宽结构，包括基座，所述基座的内侧设有横向缓冲机构，所述横向缓冲机构包括三个预应力套管，三个预应力套管均固定设置于横向缓冲机构的内部，三个预应力套管的内侧中心处均设有预应力筋，所述预应力筋的两端外侧均设有空心滑套。本发明通过弧形限位卡插入安装座的一端内侧，并使用紧固螺栓固定弧形限位卡，此时弧形限位卡配合梯形导轨对滑动卡座做限位处理，拆卸时，弧形限位卡从安装座一端取出，即可将滑动卡座从梯形导轨中滑动取出，该拼宽结构为组装式结构设计，便于安装和拆卸，且拼宽结构连接两个钢箱梁后，对两个钢箱梁可做横向以及纵向减震处理，使用功能多。
