Description

Technical Field

[0001] This utility model relates to the field of wall beam technology, specifically a wall beam reinforcement structure. Background Technology

[0002] In traditional building reinforcement projects, from the foundation to the masonry structure, due to its age, insufficient strength of the original building materials, aging of the bonding layer, and inconsistent local strength, it is easily disturbed, exacerbating the decline in stability. Currently, the industry typically uses the original construction techniques and materials to dismantle and repair severely alkali-corroded, hollow, warped, or cracked walls. For critical load-bearing areas, ring beams are used, or steel frames are implanted in concealed locations within the wall, or steel mesh is added and connected to the original structure with anchor bolts to enhance compressive and shear resistance. For cracked or loose walls, low-pressure grouting (cement grout, epoxy resin, etc.) is used. Adding concrete buttresses or wing walls on the inner side of the wall to distribute the load and improve stability is also employed. Alternatively, anchor bolts are inserted through external drilling to connect with the internal structure, forming a unified load-bearing structure. Another method involves wrapping steel sections on both sides of the wall with welding or bolts for external steel reinforcement. For the foundation reinforcement of historical buildings, methods such as micropiles, grouting reinforcement of the foundation, and foundation replacement are also used to address wall tilting caused by uneven settlement. In the reinforcement and repair of large-scale traditional industrial buildings, the renovation and reinforcement process causes significant damage to the main structure, making it difficult for workers to operate and for them to set up operating platforms. Therefore, a wall-bracing beam reinforcement structure was invented. Utility Model Content

[0057] A method for reinforcing a wall beam includes the following specific steps:

Then, the original foundation 30 is reinforced with vertical bars 32 and anchor bars 31 with a spacing of not less than 5d. Then, the original foundation 30 is closed with stirrups 47. Then, the first reinforcing bar assembly is constructed on both sides of the original foundation 30 and tied with the continuous reinforcing bars. Finally, concrete is poured on the formwork of the original brick wall 20 and the original foundation 30 to form a new anchored ground beam. The interface 46 between the new ground beam and the original foundation 30 is set as wavy.

[0059] Alternatively, when reinforcing the wall beam (i.e. the indoor and outdoor structural column part) on the basis of the original foundation 30, first anchor the first anchor bar into the original foundation 30, then construct the second steel reinforcement assembly on both sides of the original foundation 30 and tie it with the first anchor bar, and then pour concrete on the formwork of the original foundation 30 to form a new anchored ring beam as a whole.

[0060] Alternatively, when reinforcing the wall beam (i.e., the indoor and outdoor masonry structure) on the basis of the original brick wall 20, there is no need to anchor the foundation. After clearing and excavating the original foundation pad 21, plain concrete layers 60 are directly constructed on both sides of the original foundation pad 21, and reinforced concrete beams 70 are erected on the plain concrete layers 60. During the erection process, continuous steel bars 61, third stirrups 62 and tie bars 71 are set. Afterwards, the formwork is directly erected and concrete is poured together with the original brick wall 20 to form a new ring beam.
