the first convex body (3) is arranged on the second side surface of the mold, the first convex body (3) is matched with the first concave body (2), and the first convex body (3) can extend in the direction away from the mold;

the rib framework (0) is arranged in the die and used for forming a stressed frame serving as a bearing structure of the die;

the netting (4) is connected to the rib frame (0) and used for increasing the contact area of the net and the GRC and uniformly dispersing and transmitting the stress of the GRC to the rib frame (0);

wherein the different moulds are joined/connected to each other by inserting a first male body (3) of one of the moulds into a first female body (2) of another of the moulds, in order to at least prevent the hardenable material from flowing away from the first and/or second side surface to the second side surface of the mould.

2. The GRC non-dismantling mold according to claim 1, wherein the rib frame (0) comprises a plurality of main ribs (401) and a plurality of auxiliary ribs (402) connected to the main ribs (401), wherein the auxiliary ribs (402) are detachably connected to the main ribs (401) by connectors (403).

3. The GRC non-dismantling mold as claimed in claim 2, wherein the connector (403) at least comprises a main sleeve (431) for connecting the main rib (401) and a plurality of auxiliary sleeves (432), the main sleeve (431) is sleeved on the main rib (401), and two ends of the auxiliary ribs (402) are detachably connected with the auxiliary sleeves (432).

4. GRC mold-in-the-free according to claim 3, characterised in that the first concavity (2) is provided with at least a second concavity (201) extending towards the first face (1), the end of the first convexity (3) remote from the mold being provided with a second convexity (301) matching the second concavity (201),

wherein the profile dimension of the first convex body (3) is smaller than or equal to the profile dimension of the first concave body (2), and the profile dimension of the second convex body (301) is smaller than or equal to the profile dimension of the second concave body (201).

5. The GRC non-dismantling mold as claimed in claim 4, wherein the second concave body (201) is capable of extending in a first direction of the first face (1) in a manner of gradually reducing or increasing a cross-sectional area of the second concave body (201), and the second convex body (301) is capable of extending in the first direction of the first face (1) in a manner of gradually reducing or increasing a cross-sectional area of the second convex body (301).

6. The GRC non-dismantling mold as claimed in claim 5, wherein an axial centerline of the first concave body (2) is parallel to the first direction, and an axial centerline of the first convex body (3) is parallel to the first direction.

7. The GRC demolition-free mold of claim 6 wherein an axial centerline of the second female body (201) is parallel to the first direction and an axial centerline of the second male body (301) is parallel to the first direction.

8. The GRC demolition-free mold of claim 7 wherein the first face (1) of the mold is a rough face with grooves (101) and the second face is a smooth flat face, wherein the grooves (101) are U-shaped grooves.

9. The GRC break-free mold of claim 8, wherein ends of the plurality of grooves (101) distal to the first face (1) are in a same plane parallel to the first face (1), wherein the grooves (101) immediately adjacent to each other are equally spaced.

10. The GRC demolition-free mold of claim 9, wherein the main sleeve (431) is configured with a bolt (405).
