在模板支撑系统中,我们采用了由日本借鉴来的灵活钢管支撑。这种支撑,在日本是采用壁厚仅2毫米的薄壁高强钢管制作的。我们根据国内钢材情况,采用的是下管为φ60外径的钢管,长2米,上管为φ50外径的钢管,长2.20米,壁厚4.5毫米,自重比较重,但一个人可以扛得动。这种支撑的关键是在下管上端焊一加工好的螺旋管和滑盘。螺旋管中部有一长条形孔缝,以插销子。摇动滑盘,可
In the formwork support system, we have adopted flexible steel pipe supports borrowed from Japan. This kind of support is made in Japan using a thin-walled high-strength steel pipe with a wall thickness of only 2 mm. According to the situation of domestic steel products, we use a steel pipe with a diameter of φ60 outer pipe and a length of 2 meters. The upper pipe is a steel pipe with an outer diameter of φ50. It has a length of 2.20 meters and a wall thickness of 4.5 mm. The weight is heavier, but one can win. move. The key to this kind of support is to weld a finished spiral tube and sliding plate to the upper end of the lower tube. There is a long slit in the middle of the spiral tube to insert the pin. Shake the slider, can
