Description

Technical Field

[0001] The utility model relates to the field of concrete beam-column node spacing, in particular to a concrete beam-column node combined partition structure. Background Art

[0002] At present, in the design of high-seismic-grade buildings, the strength of column concrete is often higher than that of beam concrete. In order to meet the design and specification requirements and prevent high-grade concrete from flowing in the core area of ​​the joint between beams and columns, it is necessary to adopt a partition construction process to ensure that all columns are cast with high-grade concrete and reduce its loss.

[0003] The existing airbag isolation device for the beam-column joint area sets multiple inflatable airbags in the beam reinforcement skeleton to isolate concrete of different grades. However, in the prior art, when the column concrete is poured and vibrated, the airbag in the center of the beam has no effective support and only relies on the friction with the reinforcement. The airbag is easy to sink under the lateral pressure during concrete pouring, and the airbag is easily disturbed during vibration, and the contact surface is uneven; and the contact surface between the airbag and the column concrete is easy to form a smooth surface, which is not conducive to the combination of the beam concrete and the airbag; when the beam concrete is poured, the airbag is deformed under the lateral pressure of vibration. When the airbag is taken out, the airbag is large in size, and the wrong deflation time is easy to cause the concrete in the poured beam-column joint area to collapse, and the airbag in the middle of the beam is not easy to take out when the reinforcement is dense.

[0047] Reference Figure 5In this embodiment, a plurality of protrusions 260 or pits are arranged on the surface of the middle partition 200 for forming concrete.

[0048] The front of the middle partition 200, that is, the side facing the concrete, is provided with a spur 260 or a pit, which can form a rough surface on the contact surface between the concrete and the middle partition 200, which is conducive to the effective combination of the rough surface of the concrete with the subsequent pouring concrete after the middle partition 200 is removed, thereby improving the adhesion between the column concrete and the beam concrete.

[0051] The telescopic pin 210 is inserted into the first connection hole 160 or the second connection hole 220, and the edge partition 100 and the middle partition 200 are spliced ​​in sequence. Before the initial setting of the column concrete, the beam concrete is poured, and the telescopic pin 210 is withdrawn from the first connection hole 160 or the second connection hole 220, and then the middle partition 200 and the edge partition 100 are taken out in sequence.
