Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction, especially a concrete pouring isolation device. BACKGROUND

[0002] Cast-in-place concrete frame structure buildings are very common in the field of civil residential buildings, and the columns and shear walls in the frame structure usually need to bear greater loads, so higher grade concrete (such as C30 or higher) needs to be used to meet the bearing capacity and stiffness requirements, while the loads of beams, slabs and interior walls are relatively small, so lower grade concrete (such as C25 or C30) can be used. In the pouring process, the columns and shear walls are usually poured first, and then the beams, slabs and interior walls are poured. The concrete strength of the columns and shear walls is higher, which can provide better support for the subsequent construction of beams and slabs. When the design strength of the concrete of the columns and shear walls is two or more grades higher than that of the beams, slabs and interior walls, separation measures should be taken in the interface area to prevent high-strength concrete from flowing into the low-strength area.

[0003] Traditional pouring isolation uses wood pieces or shuttering nets arranged in the steel bars at the interface to isolate, which temporarily isolates the concrete by arranging wooden strips or metal nets between the steel bars at the location that needs to be isolated. After pouring high-grade concrete, the wooden strips or metal nets between the steel bars are removed after the high-grade concrete has initial set. The construction is tedious and time-consuming. In order to improve construction efficiency, a concrete isolation air bag can be used between the steel bars of the beams and columns. The isolation air bag is cylindrical and can be placed between the steel bars without inflation. Then the isolation air bag is inflated to block and isolate the concrete. After the high-grade concrete has initial set, the air bag is easily removed after deflation. However, the overall rigidity of the air bag is poor. The isolation height at the interface of the shear wall and the interior wall is usually more than 2 meters, and the transverse tie bars in the interior wall have less reinforcement, which cannot support the air bag. The air bag placed at the interface of the shear wall and the interior wall has no fixed support, which causes the air bag to bend under the pressure of the concrete, and then a large amount of high-grade concrete flows into the formwork of the interior wall, resulting in failure of concrete isolation and waste of high-grade concrete.
