Welding-free mounting method for steel trestle floor
The invention discloses a welding-free mounting method for a steel trestle floor. Cross beams are mounted on a bailey beam through a hoop I, and a longitudinal beam is mounted through a hoop II; after end clamps and middle clamps are adjusted, the end clamps and the middle clamps are placed on the corresponding cross beams; a bridge deck plate is hoisted to be paved on the longitudinal beam, moving is carried out to enable a supplement plate to be aligned with a rectangular notch, and enabling a screw II to be aligned with a circle center hole; an n-shaped plate is installed on the supplement plate through screws and fastened, the screw rod I and the screw rod II are tightened one by one, a grabbing plate I and a grabbing plate II are made to grasp the cross beam, and then installation is completed. The mounting process is simple, a grid structure capable of being quickly assembled and disassembled is formed, the bridge deck is stressed uniformly, the bearing capacity is improved compared with that of a traditional steel trestle, and the steel trestle is worthy of popularization; the installation structure is orderly and simple, adopted accessories are low in manufacturing cost, safe and reliable, high welding cost and welding time needed by a common trestle are not needed, the construction period is shortened, disassembly is convenient, and damage-free disassembly is achieved.
本发明公开了一种钢栈桥桥面免焊接安装方法，通过抱箍I将横梁安装在贝雷梁，通过抱箍II安装纵梁；将端头夹具及中间夹具调整好后，放置在对应的横梁上；吊装桥面板铺装在纵梁上，移动使补充板对准矩形缺口、螺杆II对准圆心孔；通过螺钉将几形板安装在补充板并紧固，逐个拧紧螺杆I与螺杆II，使抓板I和抓板II分别抓紧所在横梁，即完成安装。本发明安装过程较为简单，组成可快速装卸的格栅结构，使桥面板受力较为均匀，承重能力相比传统的钢栈桥有所提高，值得推广；本发明的安装结构较为有序简约、采用的配件制造成本较低，安全可靠，无需普通栈桥所需的高额焊接成本及焊接时间，缩短工期，且拆卸较为便利，为无破坏拆卸。
