[0015] Embodiment 1

[0016] As Figure 1The illustrated floor module sealing structure includes: a main beam 1, a secondary beam 2, a waterproof vapor barrier membrane 3, a caulking agent 4, and a floor surface layer 5. An L-shaped connector 11 is fixed to the top of the main beam 1 by spot welding and then applied with sealant. The ends of the secondary beam 2 are fixedly connected to the main beam 1 by full welding. The top of the secondary beam 2 is raised above the main beam 1 and flush with the upper surface of the horizontal branch of the L-shaped connector 11. A base plate 21 is laid on the top of the secondary beam 2. The waterproof vapor barrier membrane 3 is laid between the secondary beam 2 and the base plate 21. The caulking agent 4 is applied to the area enclosed by the waterproof vapor barrier membrane 3, the ends of the horizontal branch of the L-shaped connector 11, the top surface of the main beam 1, and the ends of the secondary beam 2, as well as the area enclosed by the inner corners of the L-shaped connector 11 and the waterproof vapor barrier membrane 3. The floor surface layer 5 is provided above the base plate 21. The use of the waterproof vapor barrier membrane and caulking agent prevents moisture from entering the floor, improving the sealing of the floor module without significantly increasing costs.

[0017] In this embodiment, the waterproof vapor barrier membrane 3 is folded upward along the edge of the base plate 21 and then folded horizontally toward the vertical branch of the L-shaped connector 11 at a position flush with the top surface of the base plate 21. This completely isolates the floor surface from the ground. Combined with the gaps filled with caulking agent 4, this improves the sealing of the floor module and effectively prevents moisture from entering the ground.

A gap filling area is reserved to further improve the sealing effect of the floor module.

[0022] In this embodiment, the sealant 4 is made of foamed polyurethane.

[0023] In this embodiment, the base plate 21 is fixed to the secondary beam 2 by countersunk self-tapping screws penetrating the waterproof vapor barrier membrane 3 .
