Flat joint formwork for airport pavement concrete dowel bar and construction method of flat joint formwork
The invention relates to a flat joint template for an airport pavement concrete dowel bar and a construction method of the flat joint template. Comprising construction drawing deepening design; blanking and processing the template; designing a flat joint of the pavement concrete dowel bar by a design engineer; a formwork is installed according to construction positioning; the finished dowel bar is inserted into a formwork hole, the dowel bar is inserted into a circular ring, used for fixing the dowel bar, of the combined trapezoid supporting frame, it is ensured that the dowel bar is not lowered in position under high-frequency vibration of concrete, and then the position of the dowel bar is controlled to be stable. According to the method, in the pavement concrete paving construction process, it can be ensured that the mounting position of the dowel bar is stable and is not disturbed by external factors such as mechanical running and concrete vibration, it is ensured that the dowel bar meets the position requirement of the dowel bar in a design drawing all the time in the pavement concrete paving process, and the construction efficiency is improved. Therefore, the dowel bar can more uniformly resist the shearing force generated between adjacent plates due to the collision of an airplane when being used in a runway.
本发明是一种用于机场道面混凝土传力杆的平缝模板及其施工方法；包括施工图深化设计；模板下料加工；由设计工程师进行道面混凝土传力杆平缝设计；根据施工定位安装模板；传力杆安装：将成品传力杆插入模板开孔中并将传力杆插至组合后梯形支撑架用于固定传力杆的圆环中，确保传力杆在混凝土大频率振动下不发生位置便宜，进而控制传力杆刚的位置稳定。本方法在道面混凝土摊铺施工过程中，可以确保传力杆的安装位置稳定，不受机械行驶、混凝土振捣等外部因素扰动，确保传力杆在道面混凝土摊铺过程中始终处于满足设计图纸中传力杆的位置要求，从而可以使传力杆在场道使用中更加均匀的抵抗由飞机冲撞导致的相邻板块之间产生的剪切力。
