Description

Technical Field

[0002] Shear wall, also known as wind-resistant wall, earthquake-resistant wall or structural wall, is a wall in a house or structure that mainly bears horizontal loads and vertical loads (gravity) caused by wind loads or earthquakes to prevent structural shear (shear) damage. It is generally made of reinforced concrete. When the shear wall is poured, after the grouting in the formwork, the bottom of the formwork will be subjected to greater pressure, causing the mud to leak out from the gap at the bottom of the formwork, which will not only cause waste of mud and be difficult to clean, but also affect the quality of the shear wall. A common solution is that the operator uses mud on the sealing wood strips to seal in advance to avoid mud leakage. However, the use of mud sealing will not only use a large amount of mud, but also the mud cannot be recycled after solidification, which will lead to a large amount of mud waste, and the solidified mud is difficult to clean, which greatly increases the construction cost and construction time. Therefore, in view of the above phenomenon, a leakage prevention device and construction method for the root of the high-rise frame shear wall column is urgently needed to meet the needs of actual use.
