Rapid in-place method for prefabricated reinforced concrete beam
The invention discloses a prefabricated reinforced concrete beam in-place method, and belongs to the technical field of building engineering. The prefabricated reinforced concrete beam in-place methodcomprises the following steps: (1) at the prefabricated stage of a reinforced concrete column, a sleeve is pre-buried on the top face of a bracket of the prefabricated reinforced concrete column, andan adjustable bolt is arranged in the sleeve; (2) when a prefabricated reinforced concrete beam is hoisted in place, 2-5 pieces of round steel are fixedly placed on the top face of the bracket of theprefabricated reinforced concrete column firstly, and after the prefabricated reinforced concrete beam is hoisted to the top face of the bracket of the prefabricated reinforced concrete column, the round steel is rolled to adjust the horizontal position of the beam; and (3) after the horizontal position of the prefabricated reinforced concrete beam is adjusted, the top elevation of the prefabricated reinforced concrete beam is vertically and finely adjusted by adjusting the height of the adjustable bolt in the pre-buried sleeve. By the adoption of the prefabricated reinforced concrete beam in-place method, connection of prefabricated reinforced concrete components with horizontal and vertical errors within the range of about 30 mm-50 mm found in the actual installation process can be adjusted, the error tolerance degree is high, operation is easy, and the adaptability to a construction site is high.
本发明公开了建筑工程技术领域一种预制钢筋混凝土梁就位方法，1)在钢筋混凝土柱预制阶段，在预制钢筋混凝土柱牛腿顶面预埋套筒，套筒内设置可调式螺栓；2)在预制钢筋混凝土梁吊装就位时，先在预制钢筋混凝土柱牛腿顶面固定放置2～5根圆钢，将预制钢筋混凝土梁吊放至预制钢筋混凝土柱牛腿顶面后，滚动圆钢调整梁的水平位置；3)当预制钢筋混凝土梁水平位置调好后，通过调整预埋套筒中的可调式螺栓高度，垂直微调预制钢筋混凝土梁顶标高。采用本发明可以调节实际安装过程中发现的水平、垂直误差在约30mm～50mm范围内的预制钢筋混凝土构件连接，容误差度高，操作简单，对施工现场的适应能力强。
