Construction method suitable for concrete of different grades of frame beam-column joints
The invention discloses a construction method suitable for different-grade concrete of frame beam-column joints, and belongs to the field of beam-column plate pouring. A certain distance L is formed between the top of a beam and a column side, the distance between the bottom of the beam and the column side is L + the height of the beam, a double-layer steel wire mesh and a steel wire mesh fixing system are used for separation, and column concrete is poured and fully vibrated after separation; and beam concrete is poured after the interval of 1-1.5 hours, the engineering quality at the beam-column joint of the frame is effectively guaranteed, concrete cold joints do not appear on an interface while concrete of different grades is effectively isolated during pouring, and the problem that excessive high-grade concrete of the column flows to low-grade concrete to cause economic loss is also effectively solved.
本发明公开了一种适用于框架梁柱节点不同标号砼施工方法，属于梁柱板浇筑领域，梁顶部距离柱边一定距离L、梁底部距离柱边L+梁高，使用双层钢丝网及钢丝网固定系统进行分隔，分隔后先浇筑柱混凝土并充分振捣，间隔1‑1.5小时后浇筑梁混凝土，有效保证框架梁柱节点处工程质量，不同标号砼浇筑时进行有效隔离同时分界面不出现砼冷缝，也有效解决了柱高标号混凝土过多流向低标号混凝土造成经济损失的问题。
