Description

Technical Field

[0001] The present invention relates to the technical field of sandwich wall beams, in particular to a sandwich wall beam reinforcement structure and method. Background Art

[0002] In traditional building reinforcement construction, from the foundation to the masonry structure, due to its age, the lack of strength in the original building materials, aging bond lines, and other factors, the structure's inconsistent local strength makes it susceptible to disturbances, exacerbating its stability. Currently, the industry typically uses the original construction techniques and materials to demolish and repair walls that are severely alkali-corroded, hollow, warped, or cracked. Key load-bearing areas are reinforced with ring beams or steel frames or reinforced mesh embedded in hidden locations within the wall, connected to the original structure via anchor bolts to enhance compressive and shear resistance. Low-pressure grouting (cement slurry, epoxy resin, etc.) is used to address cracked or loose walls. Concrete buttresses or wing walls are added to the interior of the wall to share loads and improve stability. External anchor bolts are inserted through external holes to connect to the internal structure, forming a monolithic load-bearing structure. Other methods include wrapping steel sections around the wall and connecting them with welded or bolted steel for external reinforcement. For historical building foundation reinforcement, micropiles, grouting, and foundation replacement reinforcement are also used to address wall tilt caused by uneven settlement. However, in the reinforcement and repair construction of large-scale industrial traditional buildings, the renovation and reinforcement cause great damage to the main structure, making it difficult for workers to operate and set up an operating platform. Therefore, a wall-beam reinforcement structure and method are invented. Summary of the Invention
