[0002] Calcium silicate board is a new type of inorganic building material made from siliceous materials, calcium materials, reinforcing fiber materials, and additives in a certain proportion, through processes such as sheet forming or molding and autoclaving. As a new type of green and environmentally friendly building material, it is widely used in ceilings and partitions of industrial and commercial buildings, linings for home decoration and furniture, and wall panels for interior projects such as tunnels.

[0003] A search revealed a fiber calcium silicate board with publication number CN218562605U, comprising a first fiber calcium silicate board and a second fiber calcium silicate board, intended to address the problem of insufficient strength caused by indirect contact between the boards. This invention connects multiple boards using a snap-fit ​​mechanism, but the snap-fit ​​mechanism lacks a stabilizing mechanism. The snap-fit ​​mechanism is prone to decreased connection stability due to deformation of structures such as tension springs, affecting the connection effect between the boards. Therefore, we propose a flame-retardant and heat-insulating calcium silicate board. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides an improved flame-retardant and heat-insulating calcium silicate board. Please refer to [link / reference]. Figures 1-2 The system includes: a plate 1, with a protrusion 2 fixed to the outer wall of the middle section of one end of the plate 1, and grooves 3 formed on both sides of the protrusion 2; a groove 3 formed on the outer wall of the middle section of the other end of the plate 1; and protrusions 2 symmetrically fixed to the outer wall of the plate 1 near the middle groove 3. The plates 1 are connected by the protrusions 2 and the grooves 3, which are used to pre-fix the two plates 1 together. A through hole 4 is formed on one side of the outer wall of both the plate 1 and the protrusion 2, extending through to the other side of the outer wall of the plate 1 and the protrusion 2. A connecting rod 5 passes through the inside of the through hole 4. The plates 1 are connected by a connecting rod 5 and a protrusion 2, forming a pin connection. The connecting rod 5 is inserted into the through hole 4 to secure the protrusion 2 and the groove 3 connecting the plates 1, preventing the two plates 1 from loosening or detaching from the connection. A partition 6 is fixed to the inner surface of the middle part of the connecting rod 5. A rotating rod 7 is inserted through the middle part of the partition 6 via a bearing, which allows the rotating rod 7 to rotate smoothly inside the connecting rod 5. A gear 8 is fitted on the outer wall of the rotating rod 7 near the partition 6. The gear 8 is rotatably connected to the connecting rod 5 through the rotating rod 7 and the lever 12. Tooth plates 9 mesh on both outer walls of the gear 8. An arc-shaped friction plate 10 is fixed to the outer wall of the toothed plate 9 at the end away from the gear 8. Guide rails 11 are fixed to the inner walls of the connecting rod 5 on both sides near the toothed plate 9, and the toothed plate 9 is positioned inside the guide rails 11. The friction plate 10 forms a telescopic connection with the connecting rod 5 through the toothed plate 9, guide rails 11, and gear 8. The connecting rod 5 also forms a snap-fit ​​connection with the through hole 4 through the friction plate 10. The friction plate 10 can extend outward from the middle outer wall of the connecting rod 5 through the action of the gear 8 and toothed plate 9. When the connecting rod 5 passes through the connection point of the two connected plates 1, it can assist in the connection. The rod 5 stabilizes the connected plate 1, improves the structural strength of the connection between the plate 1 and the plate 1, and prevents the connecting rod 5 from coming out of the through hole 4; the end of the rotating rod 7 away from the gear 8 is fixed with a paddle 12, which allows the operator to rotate the rotating rod 7 and the gear 8 at one end of the connecting rod 5; a retaining ring 13 is fixed to the outer wall of one end of the connecting rod 5, and a collar 14 is threadedly connected to the outer wall of the end of the connecting rod 5 near the paddle 12. The collar 14 and the connecting rod 5 are threadedly connected, and the connecting rod 5 is engaged with the plate 1 through the retaining ring 13 and the collar 14.

[0023] Please see Figures 2-3 A flame-retardant and heat-insulating calcium silicate board includes: a connecting rod 5 with symmetrical slots 15 on the inner wall of one end near the lever 12, the slots 15 being used to allow the lever 12 to be engaged with a locking block 18 after rotation; openings 16 on the outer walls of both ends of the lever 12, the inner walls of the openings 16 being connected to springs 17, the other ends of the springs 17 being connected to locking blocks 18, the locking blocks 18 forming an elastic telescopic connection with the lever 12 through the springs 17 and the openings 16, and the lever 12 forming an engaging connection with the connecting rod 5 through the locking blocks 18 and the slots 15, the locking blocks 18 being ejected from the surface of the lever 12 under the elastic force of the springs 17 when the lever 12 rotates to face the slots 15, so that the lever 12 engages with the slots 15, preventing the lever 12 from rotating back and causing a decrease in the static friction between the friction plate 10 and the inner wall of the perforation 4, which would affect the stability of the connecting rod 5 when it is placed inside the perforation 4.

[0024] Please see Figure 4 A flame-retardant and heat-insulating calcium silicate board includes: a microporous calcium silicate layer 19 disposed on the innermost side of the board body 1, and a fireproof coating layer 20 coated on the outer wall of the microporous calcium silicate layer 19. The microporous calcium silicate layer 19 provides basic heat insulation and flame retardant functions, and the fireproof coating layer 20 of epoxy material on the surface can effectively enhance the flame retardant and fireproof effect of the calcium silicate board body 1 and improve the durability of the board body 1.

[0025] Working Principle: For this type of flame-retardant and heat-insulating calcium silicate board, the boards 1 are first pre-connected using matching protrusions 2 and grooves 3. After the boards 1 are matched and engaged, the protrusions 2 and grooves 3 allow the perforations 4 to communicate. Then, the operator inserts a connecting rod 5 into the perforation 4. One end of the connecting rod 5 is limited by a retaining ring 13, and the other end of the connecting rod 5 extends through to the outer wall of the other end of the board 1. The operator can rotate the lever 12, which drives the rotating rod 7 to rotate the gear 8 on one side of the partition 6. The gear 8 drives the toothed plate 9 to slide inside the guide rail 11, thereby causing the friction plate 10 to extend and retract on the middle surface of the connecting rod 5. The extended friction plate 10 makes frictional contact with the inner wall of the perforation 4, increasing the static friction and improving the stability of the connecting rod 5 inside the perforation 4. This improves the connection stability and structural strength of the joint between the plates 1. When the rotating lever 12 rotates to its maximum angle, the spring 17 connected in the openings 16 at both ends of the lever 12 pushes out the locking block 18, so that the locking block 18 is inserted into the locking groove 15, making the lever 12 maintain this rotation angle and not easily rotate back. This maintains the static friction between the friction plate 10 and the inner wall of the perforation 4, and stabilizes the connecting rod 5. Then, the operator installs the collar 14 on the end of the connecting rod 5 near the lever 12 through the thread to protect the lever 12. With the friction of the friction plate 10 and the locking ring 13, the connecting rod 5 is engaged with the perforation 4, preventing the connecting rod 5 from coming out of the perforation 4. Finally, the plate 1 provides basic heat insulation and flame retardant function through the microporous calcium silicate layer 19, and the fireproof and heat-resistant ability of the plate 1 is improved by the fireproof coating layer 20 of the epoxy material on the surface.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
