本文所谈的加固办法。主要针对前定型设计事务所1955年編度的“房829”而言的。(对1956年建工部编制的“結109图集”亦可参考)。1955年以来。在铁路工业房屋中已广泛地采用了度的钢筋砼簿腹梁,使用情况基本上是好的。但是也发现了一些問題。暴露出它的缺陷,路外单位曾经发生过几次在寒冷地区脆断坍塌事故,在使用荷载作用下梁的裂缝较多。有的宽度超过了允許范围。因此有必要对这些問题加以分析研究,对已建成的工程采取必要的措施。以保証構件的正常使用和安全
This article talks about the reinforcement approach. Mainly for the former styling design firm in 1955 compiled “room 829” in terms of. (For the Ministry of Construction Construction 1956 “knot 109 Atlas” can also refer to). Since 1955. In the railway industry housing has been widely used degree of reinforced concrete Beams, the use of the situation is basically good. But also found some problems. Exposed its flaws, several times on the road outside the unit occurred brittle fracture collapse in cold areas, the use of load beam cracks more. Some width exceeds the allowable range. Therefore, it is necessary to analyze and study these problems and take the necessary measures for the completed projects. To ensure the normal use of components and safety
