Open-type temporary steel trestle
The invention relates to an open-type temporary steel trestle, and belongs to the technical field of steel trestles, the open-type temporary steel trestle comprises a temporary trestle and lifting piles fixed in a river channel, the lifting piles are distributed at the two ends of the temporary trestle, winches used for lifting the ends of the temporary trestle upwards are arranged on the lifting piles, and the temporary trestle comprises beret pieces. The beret pieces comprise upper chords and lower chords, the length of the upper chords is larger than that of the lower chords, the multiple beret pieces are arranged, the adjacent beret pieces are arranged in the length direction of the temporary trestle, the lower chords of the adjacent beret pieces are hinged to each other, hinge shafts are horizontally arranged in the direction perpendicular to the length direction of the temporary trestle, and the upper chords of the adjacent beret pieces are in lap joint with each other; the top surface length of the temporary trestle is greater than the bottom surface length to form radian; a plurality of rows of Bailey pieces are distributed at intervals in the width direction of the temporary trestle; pattern windows used for improving the bearing capacity of the temporary trestle are fixed between the adjacent beret pieces in the width direction of the temporary trestle. The temporary trestle has the effect of resisting the falling tendency of the middle of the steel trestle.
本申请涉及一种开启式临时钢栈桥，属于钢栈桥的技术领域，其包括临时栈桥和固定在河道内的提升桩，提升桩在临时栈桥两端处均有分布，提升桩上设置有用于将临时栈桥端部向上提升的卷扬机，临时栈桥包括贝雷片，贝雷片包括上弦杆和下弦杆，上弦杆长度大于下弦杆，贝雷片设置有多个，相邻贝雷片沿临时栈桥长度方向排布，相邻贝雷片的下弦杆相互铰接且铰接轴沿垂直临时栈桥长度方向水平设置，相邻贝雷片的上弦杆相互搭接；临时栈桥顶面长度大于底面长度形成弧度；沿临时栈桥宽度方向，贝雷片间隔分布有多排；沿临时栈桥宽度方向相邻贝雷片之间固定有用于提升临时栈桥承载力的花窗，本申请具有抵抗钢栈桥中部下坠趋势的效果。
