AI Technical Summary
In existing methods for constructing steel-concrete composite shear walls with edge restraint, it is difficult to remove the internal cavity template, resulting in low production efficiency. Furthermore, the process of connecting the rectangular steel pipes to the composite shear wall is cumbersome and costly.
The preparation method that does not require the use of cavity templates involves first pouring concrete for the inner leaf plate and curing it to the specified strength. Then, using a rectangular steel pipe as a side mold, concrete for the outer leaf plate is poured. The inner leaf plate is flipped over and placed on the support on the rectangular steel pipe. Grout is then filled between the inner leaf plate and the rectangular steel pipe to seal the gap, thus achieving the overall prefabrication of the rectangular steel pipe and the composite shear wall.
It enables the overall prefabrication of steel-concrete composite shear walls with edge restraint, which has high production efficiency, simple operation, low cost, reliable connection, avoids leakage of post-cast concrete on the construction site, and has better overall performance.
