我们在钢筋混凝土现浇框架梁、柱、剪力墙及水池筒壁等构件施工中,采用固模拉杆加固组合钢模板,取得了较好的效果。现将具体作法介绍如下。一、固模拉杆的构造固模拉杆由孔板和拉杆两部分焊制而成。拉杆的直径一般不小于8毫米,孔板厚度不小于2毫米,焊缝长度(双面焊)不小于30毫米。现浇混凝土墙壁厚度如果超过500毫米,而且混凝土浇筑速度过大时,应按《钢筋混凝土工程施工及验收规范》附录一的计算公式确定,以确保 In the construction of reinforced concrete cast-in-place frame beams, columns, shear walls, and pool walls, solid steel tie bars are used to reinforce the combined steel formwork, achieving good results. The specific practices are described below. First, the solid model rod structure solid model rod by the orifice plate and pull rod made of two parts welded. The diameter of the rod is generally not less than 8 mm, the thickness of the orifice plate is not less than 2 mm, and the weld length (double-sided welding) is not less than 30 mm. If the thickness of the cast-in-place concrete wall exceeds 500 mm and the concrete pouring speed is too large, it shall be determined in accordance with the formula of Appendix I of the “Specifications for Construction and Acceptance of Reinforced Concrete Engineering” to ensure the
