AI Technical Summary
In existing roof ventilation measures, galvanized steel pipes and PVC pipes are not permeable to water and air, are prone to corrosion and damage, have slow construction speed, and large drilling errors, which affect the ventilation effect and construction quality.
The modular prefabricated block design is adopted. The prefabricated block has an inverted U-shaped cross section and reserved holes on the side. Adjacent blocks are interlocked to form a venting channel. The block material is lightweight aerated concrete, which is environmentally friendly and easy to transport and install.
It improves ventilation and construction efficiency, reduces the risk of construction quality fluctuations, reduces labor costs, and enhances construction benefits and building sustainability.
