在设计有多种主、次梁交叉的现浇楼、屋盖时,设计人员往往在设计和绘制主梁配筋图中,对板及次梁在主梁的位置仅以涂黑表示,考虑的主梁高度为板顶至梁底(T型截面);设计和绘制次梁配筋图时,主梁和板也仅以涂黑和作为支座的尺寸线表示,考虑的次梁高度为板顶至次梁底(T型截面),见图1所示。设计和绘制现浇板配筋图时,主、次梁作为支座也是以尺寸线表示。这样,施工人员在施工现浇楼、屋盖时,往往会因主梁、次梁、板的负筋的相互位置而感到困惑。不是板超
In the design of cast-in-situ buildings and roofs with a variety of primary and secondary beams crossings, designers often display the main beam configuration in the design and drawing of the main beam reinforcement drawing. The height of the main girders is from the top of the slab to the bottom of the girder (T-section); when designing and plotting the secondary beam reinforcements, the main girders and slabs are also represented only by the black lines and the dimension lines used as the bearings. The considered secondary beam height is From the top of the slab to the bottom of the secondary beam (T-section), see Figure 1. When designing and plotting cast-in-situ slab reinforcement diagrams, the main and secondary beams are also referred to as dimension lines. In this way, when construction workers are constructing cast-in-place buildings and roofs, they are often confused by the mutual position of the main beams, secondary beams, and negative reinforcements of the plates.
