Construction method for opening arched door and window behind existing masonry bearing wall

Abstract

This invention relates to the field of masonry structure renovation technology, and discloses a construction method for creating arched doors and windows in existing masonry load-bearing walls. The method includes the following steps: drawing arched positioning lines on both sides of the existing wall; excavating multiple holes around the arched positioning lines; inserting support frames into each hole, with both ends of the support frames extending beyond the holes; arranging arched frames on both sides of the existing wall, with each arched frame connected to the extended ends of the multiple support frames; pouring concrete into the holes and arched frames; and removing the existing wall inside the arched positioning lines to form arched doors and windows. The construction method provided by this invention, by pouring concrete after erecting the support frames and arched frames, ensures that the poured support frames and arched frames serve as the supporting foundation for the existing wall, guaranteeing support strength and thus ensuring the stability of the existing wall after construction. Furthermore, this construction method optimizes the construction process, shortens the construction period, and significantly reduces engineering costs.
