The utility model provides a disassembly tool for the tie rod nut at the bottom of the prefabricated T-beam formwork, which comprises a bracket, a driving rod and a rotating rod. The bracket comprises a base plate arranged horizontally, two sides of the base plate are respectively provided with a vertical rod, between the two vertical rods are fixedly provided with a U-shaped support bar, the bottom height of the U-shaped support bar is the same as the height of the tie rod nut from the ground; one end of the driving rod is provided with a The other end of the nut sleeve is provided with 4 plugs which are perpendicular to the axis of the driving rod in the same circular distance; one end of the rotating rod is provided with a socket whose diameter is larger than the plug along the axis of the rotating rod; one end of the driving rod is provided with a plug which is supported on the U-shaped support bar of the bracket, and the socket of the rotating rod is connected with a plug of the driving rod. The utility model transfers the working face to the abundant space outside the formwork steel support frame through the transmission rod, and increases the working face. The steering rod uses the lever principle to remove the nut, which is labor-saving and fast.

一种预制T梁模板底部对拉杆螺母拆卸工具
本技术属于桥梁工程梁场预制T梁施工
,具体涉及一种用于拆除T梁预制台座处T梁模板对拉杆螺母的工具。
技术介绍
装配式预应力混凝土连续T梁桥采用梁场预制的方式制作T梁,梁场一般根据工程实际大小设计建设,受场地、人员、造价、存梁期限等因素限制,梁场资源配置与制梁能力应符合实际架梁需求。例如负责1100片30m、40mT梁的梁场,制梁台座40个,并配置中梁模板4套、边梁模板1套。架梁高峰期,在保证T梁质量的同时,梁场内的胎架、台座、模板等设备设施必须流水线式的高效流转,使制梁速度满足架梁需求。T梁在梁场预制台座上、模板内浇筑成型。为承受混凝土的侧压力和其他荷载,确保内外侧模板的间距能满足设计要求,需要在台座下部预埋直径为7.5cm的PVC管,作为拉筋孔道,方便设置模板间的对拉螺杆,拉筋孔道间距一般为50cm,并在模板侧边设置型钢支撑架,间距为90cm。浇筑混凝土对模板施加的力,会使对拉杆螺母咬合更紧,加上对拉孔距地面仅25cm以及型钢支撑架的阻碍,使用扳手进到支撑架间拆 ...
