Is cast-in-place concrete attic good or steel structure + ALC board good?!
The short cycle of cast-in-place steel structure high stability, light weight, does not destroy the original structure, anchorage hole cast-in-place the original wall hit double row hole spacing of ten cm each with adhesive implantation wall, wall depth of ten to fifteen cm, and the steel structure is not greater than the chemical anchor spacing bolt with wall of not less than thirty cm fifty cm fifteen cm deep into the root.
If the span is large. Or choose ALC better, after all, compared to the weight of cast a lot of small, space use rate will also be improved. But the cost of ALC is much higher than that of cast in place. As for the destruction of the original structure, you can optimize it by improving the construction plan. For example, cast in the wall after planting steel through bonding carbon fiber material reinforcement. Personally, I prefer the ALC approach. Hope to help you ~!
