Description

Technical Field

[0001] This utility model relates to the field of concrete wall technology, and in particular to a concrete crack-resistant and seepage-proof wall structure. Background Technology

[0002] Traditional concrete walls often use a single material structure, which is prone to cracking and leakage due to stress concentration. Existing technologies improve resistance to deformation through rhomboid steel structural frames, but the following problems still exist:

[0003] The diamond-shaped joints are not reinforced, and localized stress concentration can easily lead to surface damage.

[0004] The spacing between support points is too large, making it difficult to distribute the load evenly;

[0005] It has limited functionality and lacks integration of multiple functions such as heat preservation and sound insulation.

[0006] To address the aforementioned shortcomings, this invention proposes an innovative structure that integrates fractal support systems and gradient concrete. Utility Model Content
