Suspension bridge cable bent tower upper cross beam high-strength pull rod tower crane profile steel foundation
The invention provides a suspension bridge cable tower upper beam high-strength pull rod tower crane profile steel foundation. The high-strength pull rod beam tower crane foundation is composed of a fastening nut, a lower bearing plate, a high-strength pull rod, a profile steel foundation body, an upper bearing plate and an adjusting nut from bottom to top. The cross beam prestressed concrete is used as a stress structure, the tower crane profile steel foundation is fastened to the cable tower cross beam prestressed reinforced concrete through the high-strength pull rod, and the problems that in traditional suspension bridge construction, two tower cranes are adopted for constructing the suspension bridge upper structure, the cross beam structure is not damaged, the cross beam appearance is not affected, and the construction cost is low are solved. After the foundation is dismantled, materials can be recycled for construction of other similar cross beam tower crane foundations, and recycling of the materials is facilitated. According to the method, under the condition that a bridge structure is not damaged, a tower crane foundation is installed on a cable bent tower beam prestressed reinforced concrete structure; a high-strength pull rod and a cross beam structure are adopted as stress components of the tower crane foundation. Hoisting equipment is arranged by fully utilizing a cable bent tower beam structure, the equipment utilization efficiency is improved, and the equipment cost is saved.
本发明在此提供一种悬索桥索塔上横梁高强拉杆塔吊型钢基础，高强拉杆横梁塔吊基础从下至上由紧固螺母、下支承板、高强拉杆、型钢基础、上支承板、调节螺母组成。该发明专利利用横梁预应力砼作为受力结构，通过一种高强拉杆将塔吊型钢基础紧固于索塔横梁预应力钢筋砼上，解决了传统悬索桥施工采用2台塔吊施工悬索桥上部结构，不破坏横梁结构，不影响横梁外观，基础拆除后材料可周转用于其他类似横梁塔吊基础施工，便于材料的周转利用。本发明在不破坏桥梁结构条件下，在索塔横梁预应力钢筋砼结构物上安装塔吊基础；采用高强拉杆和横梁结构作为塔吊基础的受力构件。充分利用索塔横梁结构设置吊装设备，提高设备利用效率，节约设备费用。
