Profiled steel sheet laying structure suitable for support-free construction of steel-concrete composite beam bridge
The invention relates to a profiled steel sheet laying structure suitable for support-free construction of a steel-concrete composite beam bridge. The structure comprises a steel main beam compression area laying structure, a steel main beam tension area laying structure and a cantilever flange laying structure; wherein the steel main beam compression area laying structure, the steel main beam tension area laying structure and the cantilever flange laying structure each comprise a reinforced concrete bridge deck slab and a steel main beam; supporting mechanisms are arranged on the two side faces of the steel main beam of the steel main beam compression area laying structure, the two side faces of the steel main beam of the steel main beam tension area laying structure and the steel main beam cantilever side of the cantilever flange laying structure. A profiled steel sheet is arranged on the supporting mechanism, and the reinforced concrete bridge deck is arranged on the upper surface of the profiled steel sheet. The profiled steel sheet is thin and is used as a supporting template of the concrete bridge deck slab, so that the steel consumption is reduced; meanwhile, the supporting mechanism is connected with the steel main beam through at least two welding seams, fatigue cracking of the steel main beam caused by single or concentrated welding seams is avoided, and therefore the service life and the strength of the steel main beam are guaranteed.
本发明涉及适用于钢混组合梁桥无支架施工的压型钢板铺设构造，包括钢主梁受压区铺设构造、钢主梁受拉区铺设构造以及悬臂翼缘铺设构造，钢主梁受压区铺设构造、钢主梁受拉区铺设构造以及悬臂翼缘铺设构造均包括钢筋混凝土桥面板和钢主梁，钢主梁受压区铺设构造的钢主梁两侧面、钢主梁受拉区铺设构造的钢主梁两侧面以及悬臂翼缘铺设构造的钢主梁悬臂侧均设置有支承机构，支承机构上设置有压型钢板，钢筋混凝土桥面板设置于压型钢板上表面。压型钢板的厚度薄，作为混凝土桥面板的支撑模板，以节省用钢量；支承机构通过至少两条焊缝与钢主梁相连，避免焊缝单一或者焊缝集中而导致钢主梁容疲劳开裂，从而保证刚主梁的使用寿命和强度。
