Construction method of high-pier and large-span portal pier prestress bent cap supporting system based on BIM design
The invention provides a high-pier large-span portal pier prestress cover beam supporting system construction method based on BIM design, a portal pier cover beam is subjected to three-dimensional modeling through the BIM technology, the three-dimensional space relation and the load distribution size condition of the portal pier cover beam are obtained, supporting system three-dimensional design is carried out on the basis of a cover beam three-dimensional model, and the supporting system is constructed. The BIM design model is subjected to stress check calculation in simulation analysis software, a supporting system is adjusted and optimized, and finally the supporting system suitable for high-pier large-span portal frame pier cover beam construction is obtained and comprises triangular brackets, sand boxes, cross beams and bailey beams, the four pairs of socket-and-spigot type triangular brackets are oppositely pulled and fixed to the two opposite sides of the upper portions of two pier bodies in the direction parallel to the cover beam respectively, and the four pairs of socket-and-spigot type triangular brackets are fixed to the two opposite sides of the upper portions of the two pier bodies in the direction parallel to the cover beam respectively. The sand boxes are arranged on the triangular brackets, the cross beams are arranged on the sand boxes, and the bailey beams are erected and fixed to the I-shaped steel main cross beams on the two sides of the pier body in the transverse bridge direction. The problems that a traditional method is long in construction period, high in cost, large in operation difficulty, insufficient in large-span supporting system strength and the like are solved. Belongs to the field of road engineering.
本发明提供一种基于BIM设计的高墩大跨门架墩预应力盖梁支撑系统施工方法，利用BIM技术对门架墩盖梁进行三维建模，得到其三维空间关系以及荷载分布大小情况，在盖梁三维模型基础上进行支撑体系三维设计，将BIM设计模型在仿真分析软件中进行受力检算，调整优化支撑体系，最终得到适合高墩大跨度门架墩盖梁施工支撑系统，包括三角托架、砂箱、横梁和贝雷梁，四对承插式三角托架分别对拉固定于平行盖梁方向的两个墩身上部相对两侧位置，砂箱安置于每个三角托架上，横梁布置于砂箱上，贝雷梁沿横桥向分别搭设固定于墩身两侧工字钢主横梁上。以解决传统方法施工周期长、成本高、操作难度大、大跨度支撑系统强度不足等问题。属于道路工程领域。
