Abstract

Technical Field
[0001] The utility model belongs to the technical field of building engineering, and particularly relates to an expansion reinforcement belt for a basement post-cast belt. Background Art
[0002] The post-cast strip is used to backfill the temporary shrinkage deformation joints with preset values to release the shrinkage stress of concrete. However, when the post-cast strip is filled with concrete, due to the difference in pouring time, the bonding strength between the newly poured concrete and the previously solidified old concrete is poor, which leads to cracks at the connection between the new and old concrete when the post-cast strip concrete shrinks during molding, resulting in water leakage at the post-cast strip, which is particularly obvious in basement construction. In response to this, technicians proposed a technical solution for expansion reinforcement strips, which uses concrete materials mixed with expansion agents to eliminate the shrinkage phenomenon of concrete molding, and then eliminate cracks at the connection between new and old concrete.
[0003] However, when using post-cast expansion reinforcement strips, it is necessary to accurately calculate the amount of expansion concrete used to ensure that the expansion concrete can fully fill the shrinkage deformation joints and that no gaps are generated at the joints between the new and old concretes. It is also necessary to avoid excessive expansion of the expansion concrete and enlargement of the original shrinkage deformation joints, thereby affecting the safety of the entire building structure. The construction technology is difficult and has a poor fault tolerance rate. Utility Model Content
