Before the final setting of the concrete, the partition frame is taken out and the partition joint is filled with foam rods and sealant in turn, thereby ensuring the overall waterproof performance of the roof and reducing the problem of cracking in the later stage.
[0004] In order to achieve the above-mentioned purpose, according to the utility model, a fine stone concrete roof partition joint structure is provided, including a partition frame, a copper strip, a foam rod and a silicone sealant. The partition frame is arranged in a preset partition joint on the fine stone concrete roof. After the concrete is poured in layers, the copper strip is fixed to the positive corners on both sides of the partition joint. The cross-section of the copper strip is a T-shaped structure. The partition frame and the partition joint adopt a trapezoidal cross-section structure that is wide at the top and narrow at the bottom. The partition frame is taken out before the concrete is finally set, and the foam rod and the silicone sealant are filled in the partition joint from bottom to top in sequence.
[0005] Furthermore, the silicone sealant caulking height is 1 to 2 mm lower than the surface concrete.

The compartment frame 2 is first arranged in a preset partition joint, and the size structure of the compartment frame 2 matches the partition joint structure arranged vertically and horizontally. After the concrete is poured in layers, the copper strips 3 are embedded in the positive corners on both sides of the partition joint.
