薄腹梁是1954年在我国第一拖拉机厂工程中首先使用的,当时以苏联的薄腹梁( 3配筋)图集为蓝本,其后国内已生产供应 5螺纹纲筋,于是便按照我国的钢材性能以及施工条件,并参考苏联国定标准图ПК-01-05进行设计,编制或标准图集《结109》。1956年经国家建委批准作为国定标准图集而通用全国。七年以来,从全国各地实践的经验来看,在屋面承重结构中以钢筋混凝土薄腹梁来代替钢梁,对建筑企业转向工业化、节约钢材起到很
Thin belly was first used in the construction of China’s first tractor factory in 1954. At that time, it was modeled on the Soviet Union’s Atlas of Thin-Beads (3 reinforcements). Since then, it has produced and supplied 5 threaded reinforcements. The steel properties and construction conditions were determined, and reference was made to the Soviet national standard map ПК-01-05 for design, compilation or standard atlas “Knot 109”. In 1956, approved by the National Construction Committee as a national standard atlas and general nationwide. In the past seven years, from the experience of practice across the country, the use of reinforced concrete thin-web beams in place of steel beams in roofing load-bearing structures has played a very important role in the industrialization of construction companies and the saving of steel products.
