Assembly type steel trestle butt joint structure and connection method
The invention relates to the technical field of bridge construction, in particular to an assembly type steel trestle butt joint structure which comprises chord members, the number of the chord members is two, a plurality of supporting frames are arranged between the two chord members, connecting pieces are arranged on the surfaces of the supporting frames, and inclined supporting rods are arranged between every two adjacent supporting frames; the butt joint buckle plate is inserted into the groove body of one supporting frame, a through opening is formed in the surface of the butt joint buckle plate, and first preformed holes are formed in the surface of the through opening and the surface of one supporting frame; the fabricated steel trestle butt joint structure and the connecting method have the beneficial effects that the splicing pre-fixing structure is additionally arranged between the buckling grooves and the connecting plates, that is, after the connecting plates are inserted into the corresponding buckling grooves, the hanging rods are pushed into the corresponding clamping grooves, the tops of the front portions of the hanging rods are blocked by the baffles, and the hanging rods and the clamping grooves are arranged, so that the assembling efficiency is improved; in this way, pre-fixing during butt joint of the connecting plate and the buckling groove is achieved, and deflection and dislocation of the connecting plate and the buckling groove caused when the three positions of the fastening bolt are fastened are avoided.
本发明涉及桥梁施工技术领域，具体为一种装配式钢栈桥对接结构包括：弦杆，弦杆设有两组，两组弦杆之间设置有多个支撑架，支撑架的表面设置有连接片，且相邻两个支撑架之间设置有斜撑杆；对接扣板，插接在一个支撑架的槽体中，对接扣板的表面开设有通口，通口和一个支撑架的表面均开设有预留孔一；有益效果为：本发明提出的装配式钢栈桥对接结构及连接方法在扣槽和衔接板之间加装拼接预固定结构，即衔接板插入对应的扣槽后，挂杆被推入对应的卡槽中，且挂杆的前方顶部被挡板阻挡，并且挂杆和卡槽均设置两组，如此实现对衔接板和扣槽对接时的预固定，避免紧固螺栓三位置时造成衔接板和扣槽偏斜错位。
