62年初铁路专业设计院曾提出了加固薄腹梁的設計方案(以下簡称原方案,詳見专設标(62)字第0226号文附件及本刊62年第4期《工业房屋鋼筋混凝土薄腹梁的加固》)西安铁路局某車間已正式採用该方案加固了一批跨度15m的薄腹梁。通过这次施工对控制予应力筋应力的方法和今后改进設計等方面取得了一些經驗。特此提出以便在今后施工和設計时参考。一、控制予应力筋应力的方法: 在沈阳铁路局編写的“横向张拉加固鋼筋混凝土薄腹梁的三支点法”一文(以下簡
At the beginning of 62 years, the Railway Design Institute has proposed the design plan for strengthening the thin web (hereinafter referred to as the original plan, see the special standard (62) word No. 0226 attached documents and article No. 62, No. 4 “industrial buildings reinforced concrete Strengthening of thin webs ”) A workshop in Xi’an Railway Bureau has formally adopted this plan to reinforce a series of thin webs with a span of 15m. Through this construction, we have gained some experience in controlling the method of stressing the tendons and improving the design in the future. Hereby proposed for future reference in construction and design. First, the control of stress to the stress of the method: written by the Shenyang Railway Bureau “horizontal reinforcement of thin reinforced concrete beams of the three-point method” article (the following Jane
