AI Technical Summary

Technical Problem

The existing prefabricated box-type structure panels lack specialized waterproofing measures at the joints, resulting in short water penetration paths, poor waterproofing effect, and limiting the flexibility of functional space layout in rooms with water.

Method used

Waterproof connection components, including steel plates, bolts, sealant, and steel mesh, are installed at the connection points of the prefabricated box bodies. Through the connection design of notches or protrusions, multiple waterproof barriers are formed, extending the seepage path and improving the connection stability.

Benefits of technology

It achieves effective waterproofing at the joints of prefabricated boxes, improves the flexibility of house layout and waterproofing effect, and reduces the risk of water leakage.

Claims

1. A waterproof connection node of a box structure slab surface, comprising a prefabricated box, characterized in that: The prefabricated box body is provided with connecting parts on the side for splicing. When a seam is formed between two prefabricated boxes, the corresponding two connecting parts form a mating part above the seam. A waterproof connecting component is provided at the mating part. The waterproof connecting component has the functions of fixing the two prefabricated boxes and waterproofing. The connecting part is either a notch or a protrusion; When two prefabricated boxes are joined together, the connecting parts on both sides of the joint have the same shape, either a notch or a convex shape.

2. The box structure panel waterproof connection node according to claim 1, characterized in that: When all the joints are recessed, the waterproof connection assembly includes a steel plate, bolts, sealant, steel mesh, and concrete.

3. The box structure panel waterproof connection node according to claim 1, characterized in that: When all the joints are protruding, the waterproof connection assembly includes a steel plate, bolts, and sealant.

4. The box structure panel waterproof connection node according to claim 2 or 3, characterized in that: The sealant is used to fill the joints.

5. The box structure panel waterproof connection node according to claim 2, characterized in that: The steel mesh is a mesh structure formed by connecting horizontal and longitudinal steel bars.

6. The box structure panel waterproof connection node according to claim 2 or 3, characterized in that: The length of the steel plate is adapted to the side length of the prefabricated box, so that the steel plate completely covers the joint and prevents water from seeping directly from the joint.

7. The box structure panel waterproof connection node according to claim 2 or 3, characterized in that: Both the precast box and the steel plate are provided with bolt holes that correspond to each other.

8. The box structure panel waterproof connection node according to claim 1, characterized in that: When the connecting part is a notch, a pre-embedded water-stop steel plate is installed at the connecting part; the pre-embedded water-stop steel plate is used to prevent water from seeping through the gap between the old and new concrete and to extend the seepage path.
