房架式支撑模型板,是利用现有万能杆件组成的三角形房架式结构,加在模型板的水平肋木上,在样台上拼好,整体吊装使用。它改变了多年来使用背杠木固定模型和用钢筋作内拉杆的方法,不仅保证了混凝土质量,而且大大地延长了模型板的使用期限。我队先后在锉水龙大桥和高村大桥试用这种型式的模型板,效果比较显著。但由于初步使用,还有待于今后实践中进一步改进和提高。
Frame support model board, is the use of existing universal bars composed of triangular frame-type structure, added to the model board of the horizontal ribs, in the sample table spell, the overall hoisting use. It has changed over the years the use of billet fixed model and the use of steel bars as an extension rod, not only to ensure the quality of concrete, but also greatly extend the life of the model plate. Our team has tried this type of model board in the file Shuilong Bridge and Gao Village Bridge, the effect is more obvious. However, due to the initial use, it needs to be further improved and enhanced in the future.
