目前在建筑施工中,使用组合钢模已成为节约木材的有力措施。钢模一次投资费用大,但是可以周转使用几十次甚至百次以上。钢模每次使用的摊销费以及与木模费用的比较,由于算法不一造成很大差别。我们认为应以国家建筑工程预算定额为基础进行比较,方能得出较为准确的数据。我们参照原国家建委的建筑工程预算定额(修改稿)及组合钢模板技术规范资料,结合钢模的施工设计和工程实践,对钢模的工料及费用进行了计算并与河北省木模定额进行了比较。本文取煤炭系统的工业、民用建筑中使用较多和模板用量较大的矩形柱、墙、梁、平板及有梁板五种现浇钢筋混凝土构件共二十二个项目,分别取算术平均值进行分析对比。钢模的主要材料为钢模
At present, the use of composite steel molds in building construction has become a powerful measure to save wood. Steel molds have a large investment cost, but can be used dozens of times or even more than 100 times. The amortization fee for each use of the steel die and the comparison with the cost of the wood form result in large differences due to different algorithms. We believe that comparisons should be made on the basis of the national construction project budget quota in order to obtain more accurate data. We refer to the original National Construction Committee’s budget for construction projects (revised draft) and the technical specifications of the combined steel formwork. Combined with the steel mold construction design and engineering practice, we calculated the amount of material and cost of the steel form and conducted the wood mold rating with Hebei Province. Compared. In this paper, there are a total of 22 items of five kinds of cast-in-situ reinforced concrete structures, such as rectangular columns, walls, beams, slabs, and beamed slabs, that are used in industrial and civil buildings of coal systems and have a large amount of template. Analyze and contrast. The main material of steel mold is steel mold
