Description

TECHNICAL FIELD

[0001] The application relates to the field of beam-column joint construction, in particular to a high-low strength concrete pouring separation device for a beam-column joint. BACKGROUND

[0002] Both beams and columns are important components of building structures. Beams are horizontal load-bearing members used to bear roof panels and bending moments. Columns are vertical load-bearing members used to bear vertical loads of buildings. In order to improve the deformation resistance of building structures, the design principle of "strong column and weak beam" is usually adopted in modern building structure design. The design principle of "strong column and weak beam" means that the concrete strength of the column is higher than that of the beam.

[0003] In the actual construction process of concrete pouring at the beam-column joint, high-strength concrete in the column is poured first, and then low-strength concrete in the beam is poured. In order to reduce the flow of high-strength concrete in the column to the area where the beam is located, an operator usually installs a 45° inclined separation plate at the junction of the column and the beam to hinder the flow of concrete. Steel mesh is usually used as the separation plate. During construction, the steel mesh is cut into multiple modules that are suitable for the specific structure of the junction of the column and the beam, and the multiple steel mesh modules are bundled at the joint of the beam and the column using iron wire.

[0004] The related art in the above has the following defects: using steel mesh as a separation plate, on the one hand, there are a large number of holes in the steel mesh; on the other hand, after cutting, it is difficult to completely splice the steel mesh together, so the isolation effect of the steel mesh is poor, and a small amount of high-strength concrete still flows to the area where the beam is located, resulting in low construction quality.
