1 空心板梁内模目前,京珠高速公路沿线中小跨径的梁式桥大多为空心板梁,如何预制空心板梁是当务之急,因内模拆模困难一直是施工单位所关注的事。目前大多数施工单位采用空心气囊,一套内模费用3万余元。预制梁板至少得备上3套。为节约经费,我们作了一种刚度大、变形小、安装快
Hollow Beam Inner Mold At present, the beam bridges with medium and small-span beams along the Beijing-Zhuhai Expressway are mostly hollow slab beams. How to prefabricate hollow slab beams is a pressing matter of the moment. At present, most construction units use hollow airbags, a set of internal mold costs more than 3 yuan. Prefabricated beam board at least three sets. To save money, we made a stiffness, deformation, fast installation
