Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring isolation devices for beam-column nodes, in particular to a concrete pouring isolation device for beam-column nodes. Background Art

[0002] During the operation of the beam-column joint of the reinforced concrete structure, due to the stress design of the beam-column joint and other reasons, the concrete strength used in the structural column is generally greater than the concrete strength used in the structural beam. The conventional pouring method is usually divided into two steps, that is, first pouring the concrete of the structural column, and then pouring the concrete of the structural beam. In the related technology, a steel wire mesh is used to separate the high-grade and low-grade concrete at the interface of the beam and column. This steel wire mesh is placed in the steel mesh at one time without being taken out. First, high-strength concrete is poured on one side of the steel wire mesh, and then low-strength concrete is vibrated on the other side of the steel wire mesh.

[0003] For example, an isolation device for pouring concrete of different grades at beam-column joints with announcement number CN217106195U, when using the technology, includes multiple arc-shaped plug plates and multiple inflatable airbags. The inflatable airbags are arranged closely to the concave arc surface of the arc-shaped plug plates. Two adjacent arc-shaped plug plates are arranged closely to each other. A clearance groove is provided on both upper ends and both lower ends of the arc-shaped plug plates. Multiple arc-shaped plug plates are connected by connecting shafts. A plug plate connecting piece is provided in each of the two clearance grooves at the upper end of each arc-shaped plug plate. A connecting ring is provided on the plug plate connecting piece. The utility model has a reasonable structural design, and can intercept concrete through the rigidity of the arc-shaped plug plates themselves, and protect the inflatable airbags at the same time. The inflatable airbags can prevent the occurrence of slurry leakage during concrete pouring after being inflated, thereby improving the appearance effect and construction quality of concrete isolation. The arc-shaped plug plates are fixed by connecting shafts, and can adapt to different beam sections, thus realizing rapid disassembly and assembly, and repeated use, shortening the construction period, and reducing construction costs.

[0004] The above device has some problems. The device is cumbersome to use, and the fixing effect between the isolation device and the outside is poor during use. In addition, the isolation effect during the casting process is not good, and the effect of use is poor.

[0005] Therefore, we propose a beam-column joint concrete pouring isolation device to solve the above-mentioned problems. Utility Model Content
