Claims

1. A detachable roof separating joint device installed in a concrete cover (5), characterized in that: Includes a base (1), a keel (2) is provided above the base (1), two base side plates (11) are arranged parallel to each other along the length direction on the upper surface of the base (1), and keel side plates (21) are arranged vertically downward on both sides of the keel (2) and are parallel to the two base side plates (11). The cavity formed between the base side plate (11) and the keel side plate (21) is filled with a buffer layer (4), and water-stop strips (3) are symmetrically provided on the outer walls of both sides of the keel side plate (21).

2. A demountable roof separating joint device according to claim 1, characterised in that: The cross-sectional shape of the buffer layer (4) matches the cavity outline formed by the base (1), the keel (2), the base side plate (11), and the keel side plate (21), and its height is equal to the distance from the top surface of the base (1) to the bottom surface of the keel (2).

3. A demountable roof separating joint device according to claim 1, characterised in that: The base (1) has anti-slip textures or anchoring structures at the bottom to enhance the bonding force with the concrete protective layer (5).

4. A demountable roof separating joint device according to claim 1, characterised in that: The base (1) is made of PVC material, and the keel (2) is made of galvanized light steel.

5. A demountable roof separation joint device according to claim 1, wherein: The buffer layer (4) is made of extruded polystyrene board.

6. A demountable roof separating joint device according to claim 1, characterised in that: The waterstop strip (3) is an elastic waterproof material that expands completely to fill the gaps after being exposed to water.
