AI Technical Summary
Existing reinforced concrete composite truss slabs are difficult to adjust precisely and lock stably during installation, and are prone to positional displacement due to external forces or vibrations, affecting structural stability and safety.
Design a truss reinforced concrete composite slab structure including fine-tuning components and fixing components. Through the cooperation of cylinders and ratchet racks, precise positioning and locking can be achieved to prevent height changes.
It achieves precise adjustment and stable locking within the millimeter range, avoiding positional displacement caused by external forces or vibrations, and improving the stability and safety of the structure.
