Description

Technical Field

[0001] This utility model relates to the field of fiber cement board technology, specifically to an assembled fiber cement board. Background Technology

[0002] Fiber cement board refers to a type of board made from cement as the basic material and adhesive, and mineral fiber cement and other fibers as reinforcing materials, through processes such as pulping, molding, and curing. Fiber cement board has good waterproof, fireproof, and sound insulation properties, and it is not prone to termites, rot, or corrosion. Due to its superior performance, it is widely used in various fields of the construction industry.

[0003] A search revealed a prefabricated high-strength fiber cement board with publication number CN222252557U. The board includes a panel body with a limiting block fixedly connected to one end of its outer side. This design addresses the problem of cumbersome, time-consuming, and labor-intensive splicing of multiple fiber cement boards, hindering rapid assembly. While this practical application uses a spring-loaded engagement mechanism to assemble multiple fiber cement boards, the spring mechanism's deformation capability makes it prone to wobbling after assembly, resulting in unstable assembly. Therefore, we propose a prefabricated fiber cement board. Utility Model Content

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.

[0021] This utility model provides an improved assembled fiber cement board, please refer to [link / reference]. Figures 1-3 The system includes: a cement board body 1, with connecting holes 2 on both outer walls of the cement board body 1; first wedge grooves 3 on both outer walls of the upper end of the cement board body 1; and second wedge grooves 4 on the inner side of the first wedge grooves 3. The first wedge grooves 3 and the second wedge grooves 4 have matching external shapes, and the connecting holes 2 extend through to the upper inner wall of the second wedge groove 4. An insertion hole 5 is provided on the lower inner wall of the second wedge groove 4. The insertion hole 5 serves as a redundant structure to accommodate the protruding lower part of the fastened connecting screw 9, thereby stabilizing the connecting screw 9 and preventing the wedge plate 8 from coming out of the second wedge groove 4. A sleeve 6 is embedded in the inner wall of the connecting hole 2 near the upper end of the first wedge groove 3 and the second wedge groove 4. The inner surfaces of the first wedge groove 3 and the second wedge groove 4 are both fixed with tenon pieces 7. The interior of the first wedge groove 3 and the second wedge groove 4 is equipped with wedge plates 8. The interior of the connecting hole 2 is provided with a connecting screw 9 through a sleeve 6. The first wedge groove 3 and the second wedge groove 4 are symmetrically arranged about the central axis of the cement board. The cement boards are connected by the connecting screw 9 and the wedge plates 8. The connecting screw 9 and the wedge plates 8 are used to assemble the cement board body 1. The wedge plates 8 are connected to the first wedge groove 3 and the second wedge groove 4 by tenon and mortise, and the connecting screw 9 is threaded to the wedge plates 8 in the connecting hole 2. This enables the rapid assembly and fastening of multiple cement boards with good assembly effect.

[0022] Please see Figure 4 A prefabricated fiber cement board includes: a wedge plate 8 with a marking line 801 in the middle; screw holes 802 on the upper surfaces of both ends of the wedge plate 8, extending to the lower outer wall of the wedge plate 8; the screw holes 802 serve as a connecting structure for connection and fastening with a connecting screw 9; mortises 803 on the outer walls of both ends of the wedge plate 8; the wedge plate 8 is connected to the first wedge groove 3 and the second wedge groove 4 by means of the mortises 803 and the tenon 7; and the cement board bodies 1 are connected by mortise and tenon joints through the wedge plate 8, the first wedge groove 3 and the second wedge groove 4. The mortises 803 are used to securely fix the wedge plate 8 in the first wedge groove 3 and the second wedge groove 4 by means of the mortise and tenon joints when the wedge plate 8 is inserted into the first wedge groove 3 and the second wedge groove 4, preventing the wedge plate 8 from coming out of the cement board bodies 1 after installation.

[0023] Please see Figure 5A prefabricated fiber cement board includes: a square groove 901 at the top of a connecting screw 9, and a connecting thread 902 on the outer wall of the lower end of the connecting screw 9. The connecting screw 9 is threadedly connected to a wedge plate 8 through the connecting thread 902 and the screw hole 802. The connecting thread 902 and the screw hole 802 are matched to facilitate the threaded connection between the connecting screw 9 and the wedge plate 8. A square protrusion 903 is fixed on the outer wall of the lower end of the connecting screw 9. The square protrusion 903 matches the outer dimensions of the square groove 901. The connecting screws 9 are engaged through the square protrusion 903 and the square groove 901. The square protrusion 903 and the square groove 901 are used to engage the upper connecting screw 9 with the lower connecting screw 9 and rotate synchronously to connect and fasten the connecting screw 9 to the wedge plate 8 through the connecting thread 902 and the screw hole 802.

[0024] Working principle: For this type of prefabricated fiber cement board, the worker first places the cement board body 1 in the installation position, inserts the wedge plate 8 into the first wedge groove 3 and the second wedge groove 4 on one side of the single cement board body 1. When the worker taps the wedge plate 8 into place, the worker confirms that the wedge plate 8 is inserted to a sufficient depth by using the marking line 801. After fixing, the wedge plate 8 engages with the tenon piece 7 inside the first wedge groove 3 and the second wedge groove 4 through the mortise 803, so that the wedge plate 8 and the cement board body 1 form a mortise and tenon structure. Then, another cement board body 1 is connected through the wedge plate 8. Subsequently, after the two cement board bodies 1 are connected through the wedge plate 8, the first wedge groove 3 and the second wedge groove 4, the worker uses the sleeve 6 to... The connecting screw 9 is inserted into the connecting hole 2 by the guiding action of the connecting screw 9. After the first connecting screw 9 passes through the screw hole 802 via the connecting thread 902, it continues to move towards the insertion hole 5. The second connecting screw 9 is inserted and engaged with the first connecting screw 9 via the square groove 901 and the square protrusion 903. The limiting action of the insertion hole 5 ensures that the connecting screw 9 is tightly connected to the wedge plate 8 in the first wedge groove 3 and the second wedge groove 4 after rotation and tightening, thereby strengthening the wedge plate 8 in the first wedge groove 3 and the second wedge groove 4. Finally, the multiple cement board bodies 1 are assembled by the connecting screw 9 and the wedge plate 8. The multiple cement board bodies 1, reinforced by the mortise and tenon structure and fasteners, are tightly connected and not easily shaken or shifted.
