Formwork and construction method for concrete pouring of concrete slab-steel truss composite beam
The invention discloses a formwork for concrete slab-steel truss composite beam concrete pouring and a construction method, and relates to the field of bridge concrete machining. The upper portion of a formwork body is reliably connected with a prefabricated concrete slab through a plurality of truss type pull rods, and the lower portion of the formwork body is reliably connected with an inverted-pi-shaped steel bottom plate through sliding rails and limiting holes; a plurality of longitudinal stiffening ribs and a plurality of vertical stiffening ribs are arranged on the surface of the outer side of the formwork body, and the bearing capacity and lateral stiffness of the slidable formwork system can be remarkably improved through the three structures. The truss type pull rods, the formwork connecting plates, the sliding rails and the like can be flexibly arranged according to construction requirements, the truss type pull rods have the length adjusting function, and the formwork body has good flexibility. After the slidable formwork system is installed according to the design, concrete can be poured by inserting the limiting clamping blocks, after construction is completed, the expansion screws and the limiting clamping blocks are removed, the formwork body can slide along the sliding rails to enter the next section, the whole construction process is easy to operate, and the construction efficiency is extremely high.
本发明公开了一种用于混凝土板‑钢桁组合梁混凝土浇筑的模板及施工方法，涉及桥梁混凝土加工领域，模板本体上部通过若干桁架式拉杆与预制混凝土板可靠连接，模板本体下部通过滑轨和限位孔实现与倒π形钢底板可靠连接，在模板本体外侧表面布置若干纵向和竖向加劲肋，这三部分构造可显著增加可滑动模板体系的承载力和抗侧刚度。若干桁架式拉杆、模板连接板、滑轨等可按照施工需求灵活布置，且桁架式拉杆具有长度调节功能，模板本体具有很好的灵活性。本发明按照设计完成可滑动模板体系的安装后，插入限位卡块即可浇筑混凝土，施工完成后，拆除膨胀螺钉和限位卡块，即可沿着滑轨滑动模板本体，进入下一节段，整个施工过程操作简单，施工效率极高。
