Description

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are poured into a mold to form a predetermined shape. The load-bearing column of a building may require higher strength concrete due to the need to bear large vertical loads and provide overall stability, while the floor or beam may use lower strength grade concrete to save cost or reduce structural weight. Therefore, during the concrete pouring process, the isolation of different strength grade concrete is a key link to ensure structural performance and cost savings.

[0003] Currently, the existing concrete pouring device is used by inserting multiple air bags side by side in the steel reinforcement frame. The air bags are inflated to fill the gap between the steel reinforcements, and can be deflated and removed after pouring. This not only makes operation convenient, but also can be reused and has low cost. However, in actual use, the bottom end of the air bag is clamped in the steel reinforcement frame, while the top end is often suspended, making the inflated air bag end prone to tilt and shift. The overall stability between the side-by-side arranged air bags is poor, affecting the use effect. UTILITY MODEL CONTENT
