Description

Technical Field

[0001] The present invention relates to a concrete pouring assembly template for repairing corners of concrete walls or columns, and in particular to an assembly template for repairing missing corners of cast-in-place concrete walls or columns by pouring additional concrete grouting and a supplementary pouring method thereof. Background Art

[0002] During the concrete pouring construction process, the corners of concrete walls or concrete columns are often missing due to many reasons such as insufficient concrete pouring and vibration, loose assembly of old formwork, improper formwork removal, failure to take protective measures and collisions. In another case, large honeycombs appear at the corners, requiring secondary grouting repairs at the corners. If traditional wooden formwork is used, the formwork grouting at the corners is difficult to operate on site due to the reinforcement method, repair location and limitations of the wooden formwork itself. The poor quality of the concrete corners after repair often requires secondary repair and polishing. Summary of the Invention
