框架结构设计施工中的问题及预防措施

结合工程实际情况,阐述了钢筋混凝土框架结构中梁、板、柱在设计施工中的一些注意事项及构造问题,主要从五个方面进行论述。第一,结点和梁端钢筋过密造成安全隐患;第二,楼板厚度的取值;第三,梁柱和板的混凝土强度等级不一致的现浇框架结构中,易出现安全隐患;第四,关于板支座负筋最小植和保护层问题;第五,关于梁和柱钢筋混凝土保护层厚度取值问题。并且对每一方面均提出相应的预防和处理办法。

Some problems and preventive measures of design and con struction of frame structure

Combining with practical condition of project, the paper recounts matt ers needing attention and structural problems of beams, slabs and column of rein forcing concrete frame structure in design and construction. The paper mainly di scusses from five aspects. 1 Too close rebars in nodes and beam?ends cause hid d en trouble of the safety 2 sampling of floor thickness 3 hidden trouble of the safety easily appears in cast?in?place frame structure which concrete strengt h rank between beam column and slab shows difference 4 sampling of slab seat shou lder bar minimum and problems of antiabrasion layer 5 thickness sampling of bea m and column reinforcing concrete antiabrasion layer. The paper puts forward app ropriate preventive and treating measures for every aspect.
