Transverse limiting device for steel box girder dragging construction and using method
The invention relates to a transverse limiting device for steel box girder dragging construction and a using method, and relates to the technical field of bridge construction. Due to the fact that a containing cavity used for containing limiting plates in the selectable number is formed in a limiting box, one end of a positioning box extends into the limiting box and abuts against the limiting plates, and when a to-be-dragged beam body makes close contact with the other end of the positioning box in the dragging process, one end of the positioning box abuts against the limiting plate, a counter-acting force enabling the to-be-dragged beam body to move in the reverse direction of transverse deviation can be generated to act on the to-be-dragged beam body, and then transverse deviation of the to-be-dragged beam body can be prevented. Meanwhile, the position of the positioning box can be adjusted by increasing or decreasing the number of the limiting plates, and the limiting amount is adjusted; in addition, due to the fact that the limiting box is fixedly connected with the bridge pier top, the connecting contact surface of the transverse limiting device and the bridge pier top is increased. Therefore, according to the embodiment of the invention, the transverse deviation of a steel girder in the dragging process can be effectively controlled, the limiting amount can be adjusted,and the stability is improved.
本申请涉及一种钢箱梁拖拉施工横向限位装置及使用方法，涉及桥梁施工技术领域，由于限位箱内设有一用于数量可选的收容限位板的容纳腔，而定位箱的一端伸入限位箱内并抵持于限位板上，因此，当待拖拉梁体在拖拉过程中与定位箱的另一端紧密接触时，定位箱的一端与限位板相抵持，会产生一个使待拖拉梁体朝横向偏移的反方向运动的反作用力作用于待拖拉梁体上，进而可防止待拖拉梁体发生横向偏移；同时可通过增减限位板的数量来调节定位箱的位置，实现限位量的调节；此外，由于限位箱与桥梁墩顶固连，增大了横向限位装置与桥梁墩顶的连接接触面。因此，本申请实施例不仅可有效控制钢梁拖拉过程中的横向偏移，还可以调节限位量，提高稳固性。
