Process for cast-in-place box girder finish rolling deformed steel bar tensioning construction
The invention discloses a process for cast-in-place box girder finish rolling deformed steel bar tensioning construction, which comprises the following steps of: 1, manufacturing a plastic cup: firstly, adopting a recycled plastic bottle, and cutting off one end of a bottle opening of the plastic bottle to form the plastic cup; then a concentric round hole is cut in the center of the bottom of the plastic cup; secondly, fixing the plastic cup, to be more specific, sleeving the plastic cup prepared in the first step on a base plate of the finish-rolled deformed steel bar through a round hole, and tightening a nut to enable the nut to be tightly pressed in the plastic cup; and 3, filling the plastic cup: filling the plastic cup with foam glue by using a foam machine for fixing. According to the construction technology, time and labor are saved, the plastic cup can be reused, the cost input is very small, foam glue is injected into the plastic cup, the plastic cup is firmly fixed, the shape and the position of the finally formed tensioning notch are standard, great convenience is provided for subsequent tensioning construction, a large amount of precious time is saved, and the construction efficiency is improved.
本发明公开了一种用于现浇箱梁精轧螺纹钢张拉施工的工艺，该张拉施工工艺包括以下步骤：第一步、塑料杯制作：首先采用回收的塑料瓶，将塑料瓶瓶口的一端剪去，形成一个塑料杯；然后在塑料杯底部的中央剪出一个同圆心的圆孔；第二步、塑料杯固定：将上述步骤制备好的塑料杯由圆孔套在精轧螺纹钢的垫板上，然后将螺母拧紧，使螺母紧紧压在塑料杯的内部；第三步、塑料杯填充：使用泡沫机，向塑料杯内打满泡沫胶进行固定。本发明施工工艺省时省力，塑料杯能重复利用，成本投入很小，在塑料杯内打入泡沫胶，将塑料杯牢牢地固定，最后形成的张拉槽口形状、位置较为标准，为后续张拉施工提供了极大的便利，节省了大量的宝贵时间，提高了施工效率。
