[0057] Through the above methods, the reinforcement problem of large-span (large cantilever) beams can be solved, and both economy and safety are improved.
[0058] Therefore, the utility model provides a method for reinforcing large-span (large cantilever) beams, in which new beams are set on both sides of the large-span (large cantilever) beams. At the same time, the new beams are higher and are connected to the original large-span (large cantilever) beams by embedded reinforcement to form a whole, forming a concave beam structure. The concave cross-section of this structure greatly increases the moment of inertia, so it is subjected to greater force and saves materials at the same time.
[0059] In summary, the large-span beam reinforcement structure of the present invention can reinforce large-span beams while saving materials, thereby reducing material costs. It has a clever design, a simple structure, simple construction, and low construction costs, and is suitable for large-scale promotion and application.
[0060] It can be seen that the purpose of this utility model has been fully and effectively achieved. The functional and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the principles described, the embodiments may be modified in any way. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
