Problems solved by technology
Because the spacing between the steel bars of the beam is small and the height of the beam is high, it is particularly difficult to bind the steel wire mesh, which is a serious waste of manpower, and because the steel wire mesh is not taken out after the partition, it has caused a serious waste of the steel wire mesh

The invention relates to the technical field of concrete pouring, in particular to a separated pouring construction method for concrete of different strength grades at a beam-column joint. According to the separated pouring construction method, the cost is reduced, it is convenient to disassemble and assemble, slurry leakage during concrete pouring is effectively reduced, the pouring quality of beam column concrete junctions of different strength grades can be effectively ensured, labor and material cost for binding a partition steel wire mesh is saved, and the construction progress is accelerated. The method comprises the following steps that S1, construction preparation is conducted, and specifically, material preparation, construction equipment, personnel preparation and technical preparation are conducted; S2, a formwork is erected, and reinforcing steel bars are bound; S3, a combined steel formwork and a movable inserting plate are installed, wherein the combined steel formwork and the movable inserting plate are inserted into the position 500 mm away from the column edge; S4, concrete pouring is conducted, specifically, high-strength-grade concrete is poured in the column andwithin the range of 500 mm of the column edge firstly, and low-strength-grade concrete of a two-span beam plate starts to be poured immediately after two-span pouring is completed; and S5, the steelformwork and the movable inserting plate are dismounted.
Description
technical field [0001] The invention relates to the technical field of concrete pouring, in particular to a construction method for separate pouring of concrete with different strength levels at beam-column joints. Background technique [0002] There are more and more high-rise buildings in today's society. Because of the design principle of "strong columns and weak beams", the strength level of column concrete in frame structures is generally higher than that of beam-slab concrete. During concrete pouring construction, how to effectively divide and pour concrete of different strength grades for beams and columns has always been a difficult problem. [0003] The traditional beam-column concrete interface of different strength grades is generally separated by binding steel wire mesh to separate concrete of different strength grades. Because the spacing between the steel bars of the beam is small and the beam height is high, it is particularly difficult to bind the steel wire...
