Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to a support beam haunch structure. BACKGROUND

[0002] In modern building engineering, support beams are an important part of the load-bearing structure, and their design and construction directly affect the overall performance of the building. Traditional support beams usually have rectangular or T-shaped cross-sections, which may not meet the requirements of high strength and high stability in some cases. With the advancement of building materials and technology, various new support beam structures have emerged to improve the safety and economy of the structure. However, existing support beam designs still face many challenges when facing complex stress conditions, especially when subjected to large or dynamic loads, which can cause local stress concentration, fatigue cracks, and other problems that affect the safety of the structure and increase maintenance costs.

[0003] Currently, to solve the problems of traditional support beams under complex stress conditions, common solutions include increasing the height, width, or thickness of the beam, using high-strength steel, or reinforcing the nodes through welding. However, each of these methods has its own advantages and disadvantages:

[0004] Increasing the height or width of the beam can effectively improve the carrying capacity, but it also increases the self-weight, affecting the economic efficiency of the overall structure.

[0005] Using high-strength steel can improve strength, but it is more expensive and may cause corrosion problems in certain environments.

[0006] Welding reinforcement nodes is a common reinforcement measure, but they are prone to weld cracking over time, affecting the durability of the structure. Although the above methods have improved the performance of support beams to some extent, there are still obvious shortcomings. First, simply relying on increasing the size or material strength cannot completely solve the problem of local stress concentration, and may even lead to excessive redundancy of the structure, increasing unnecessary construction costs. Second, welding reinforcement nodes are prone to fatigue damage over time, especially for structures subjected to dynamic loads, which poses a greater risk. Finally, existing support beam designs lack flexibility and are difficult to adapt to different types of loads and environmental conditions, limiting their widespread application.
