近来模板出现了不少新材料、新工艺,但还是不能全部满足施工要求。传统的木模板和混凝土施工工艺,在实际施工中仍占有一定的比例。可采用钢木结合法代替传统作法。现介绍适用于木模板的工具式钢卡具。一、矩形钢筋混凝土柱模卡具制作:用角钢焊成直角L形,端部钻直径D为18毫米的销孔,见图1,使a(b)=混凝土截面长(宽)度+15+2d,d为模板厚
Recently, many new materials and new techniques have appeared in the template, but they still cannot fully meet the construction requirements. The traditional wood formwork and concrete construction technology still occupy a certain proportion in actual construction. Steel-wood bonding can be used instead of traditional practices. Now introduce tool steel fixtures for wood formwork. First, the production of rectangular reinforced concrete column clamps: angle welded into a right angle L-shaped, the end of the drill hole diameter D 18mm pin hole, see Figure 1, so that a (b) = concrete section length (width) +15 +2d, d is the template thickness
