Assembled steel keel partition concealed waterproof structure
The concealed waterproof structure, which combines a flexible waterproof membrane with vertical keel, solves the problem of cracking in the rigid waterproof layer of prefabricated keel panel walls. It achieves a highly reliable waterproof effect under temperature changes and slight structural settlement, thus improving the waterproofness and aesthetics of the building.

AI Technical Summary
The rigid waterproof layer of prefabricated keel board wall is prone to cracking when subjected to temperature deformation and slight structural settlement, resulting in poor waterproof reliability and inability to effectively adapt to later wall deformation, thus posing a risk of water seepage.
The concealed waterproof structure combines a flexible waterproof membrane with vertical keel. The membrane is fixed in sections by fixing it in the middle and at the ends, and the membrane is kept taut by a membrane pressing device, forming a structural system of "middle constraint + edge anchoring".
It improves the deformation adaptability of the waterproof layer, avoids the formation of cracks, enhances the reliability and durability of the waterproof system, and improves the waterproofness and aesthetics of the building.
