在现浇混凝土框架施工中,梁柱接头部位很容易出现跑模、漏浆等质量问题。主要原因是梁柱接头部位截面复杂,模板不易加固,在混凝土浇捣过程中,模板很容易被振移位,造成跑模、漏浆等质量通病。通过几个工程的实践,我们摸索出一种框架梁柱接头部位定型模板施工方法,以确保框架梁柱接头部位的质量。按以往习惯施工方法,在混凝土框架梁柱接头部位,用普通钢模板在阴阳角支模,常常因柱截面不符合模数.需要补充部分木模板。钢模与木模的连接困难,只能用钉
In the construction of cast-in-place concrete frames, the quality of the joints in the beam-column joints is easy to run. The main reason is that the section of beam-column joints is complex, and the formwork is not easy to be reinforced. During the concrete pouring process, the template can easily be displaced by vibration, resulting in the running of molds, leakage of plasma and other common defects. Through the practice of several projects, we have explored a construction method for setting the formwork of the beam-column joint of the frame to ensure the quality of the joints of the frame and beam column. According to past customary construction methods, in the joints of concrete frame columns and columns, ordinary steel formwork is used to support the molds at the yin and yang corners, often because the column section does not conform to the modulus. Some wood templates need to be added. The connection between the steel mold and the wood mold is difficult and only nails can be used
