(三)现浇钢筋混凝土现浇钢筋混凝土一般有现浇柱、梁、板、墙、楼梯及阳台、雨罩等项目,工程量均根据图示尺寸(结构尺寸)按混凝土的体积计算,单位为立方米。根据工程结构的受力要求设计的柱、梁、板、墙等往往是交叉设置,相互依存形成整体。编制工程预算却不能交叉计算,而应按件按根分开计算。一、现浇钢筋混凝土柱子1.一般柱。柱子有方柱、圆柱、多边柱等。柱断面面积乘以柱高即得柱体积。柱高自柱基顶面算至柱顶;遇楼层时,算至上层顶板面。多层框架柱,按每层层高计算。由于含钢量不同,预算定额中将柱分为周长为1.8米以内及1.8米以外两种情况,计算时应注
(3) In-situ cast reinforced concrete cast-in-place reinforced concrete generally has cast-in-situ columns, beams, plates, walls, stairs, balconies, rain covers, etc. The amount of work is calculated according to the size of the drawings (structure size) according to the volume of the concrete. It is cubic meters. The columns, beams, plates, and walls that are designed according to the force requirements of the engineering structure are often cross-set and interdependent to form a whole. The preparation of project budgets cannot be cross-counted but should be calculated separately according to the roots. First, in-situ reinforced concrete pillars 1. General column. Columns have square columns, columns, and polygonal columns. The column cross-section area multiplied by the column height gives the column volume. The height of the column is calculated from the top of the column base to the top of the column; when it meets the floor, it is counted as the top plate surface. Multi-layer frame columns, calculated for each layer height. Due to the difference in steel content, the column is divided into two cases with a perimeter of 1.8 meters or 1.8 meters in the budget quota.
