Description

Technical Field

[0001] This utility model relates to the field of fiber cement flat panel technology, and in particular to a spliced ​​fiber cement flat panel. Background Technology

[0002] In existing technologies, the splicing structure of fiber cement flat panels generally suffers from a single connection method and limited splicing direction, making it difficult to achieve synchronous expansion and splicing in both the horizontal and vertical directions. This results in multiple panels failing to form a stable overall structure. This limitation makes the spliced ​​surfaces prone to misalignment, cracking, and even detachment. The poor structural stability is particularly pronounced when subjected to external vibrations or changes in environmental temperature and humidity, severely impacting construction quality and safety, and hindering its widespread application in prefabricated buildings. Therefore, we propose a splicing fiber cement flat panel. Utility Model Content

[0003] The main objective of this invention is to provide a spliced ​​fiber cement flat panel that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A spliced ​​fiber cement board includes a cement board body, a first connecting side plate fixedly connected to the right end of the cement board body, a first connecting piece fixedly connected to the left end of the cement board body and cooperating with the first connecting side plate, a second connecting side plate fixedly connected to the lower end of the cement board body and the right part of the second connecting side plate extending to the lower end of the first connecting side plate, and a second connecting piece fixedly connected to the upper end of the cement board body and cooperating with the second connecting side plate.

[0006] The first connecting side plate has a first connecting groove inside that matches the first connecting piece. A first protrusion is fixedly connected in the first connecting groove. The second connecting side plate has a second connecting groove in the middle that matches the second connecting piece. A second protrusion is fixedly connected in the second connecting groove, and the size of the second protrusion is the same as that of the first protrusion.

[0007] Preferably, the upper and lower walls of the first connecting groove are provided with sliding grooves, and the upper and lower walls of the first connecting groove are provided with four positioning holes, with two positioning holes arranged symmetrically on the front and rear sides of the sliding groove in a group.

[0008] Preferably, the internal structure of the second connecting groove is the same as that of the first connecting groove.

[0009] By adopting the above technical solution, all connecting components are designed in a standardized manner with uniform dimensions, which facilitates large-scale production and assembly and is conducive to the promotion and application in the field of prefabricated buildings.

[0010] Preferably, the second connecting component includes a connecting block, which is fixedly installed in the upper middle part of the cement slab body. Both ends of the connecting block are integrally formed with sliding strips that are adapted to the sliding groove in the second connecting groove. The upper end of the connecting block has a groove that is adapted to the second protrusion. The connecting block is fixedly engaged in the second connecting groove through the groove.

[0011] By adopting the above technical solution: since the sliding groove is set on the upper and lower groove walls of the connecting groove, the sliding strip on the connector can slide and insert along the sliding groove, further guiding the connector to accurately enter the connecting groove, and providing guidance and support, avoiding deviation or jamming during installation.

[0012] Preferably, the connecting block has two symmetrical movable cavities, each of which is slidably connected to a movable plate. Each of the two movable plates has four insert rods that are adapted to the positioning holes in the second connecting groove, fixedly connected to the side of each movable plate away from the opposite end. Each of the two movable plates has a spring fixedly connected to the end away from the insert rods, and the end of the spring away from the movable plate is fixedly connected to the inner wall of the movable cavity.

[0013] By adopting the above technical solution, the spring rebound pushes the movable plate, causing the insertion rod to extend and insert into the positioning hole in the inner wall of the connecting groove, thereby achieving a firm lock.

[0014] Preferably, the front groove wall of the movable cavity has a guide groove that penetrates the front end of the connecting block, and the front end of the movable plate is fixedly connected to a pull rod that is slidably connected to the guide groove.

[0015] By adopting the above technical solution, the extension and retraction of the insertion rod can be manually controlled by the pull rod, allowing the connector to be quickly inserted or pulled out, which facilitates on-site construction and subsequent maintenance, and improves the practicality of the product and the user experience.

[0016] Preferably, the structure of the first connector is the same as that of the second connector, and the connection method between the first connector and the first connecting side plate is the same as that between the second connector and the second connecting side plate.

[0017] By adopting the above technical solution: the structure of connector No. 1 is the same as that of connector No. 2, and the connection method between connector No. 1 and connector No. 2 is also the same as that between connector No. 2 and connector No. 2. Therefore, whether it is horizontal or vertical splicing, the uniform connection strength and operation method can be guaranteed, thereby improving the compatibility and standardization of the overall system.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting No. 1 connecting side plates and No. 1 connecting parts at both ends of the main body of the cement slab, rapid lateral splicing between adjacent cement slabs is achieved. The splicing process is simple to operate and the connection is tight. At the same time, No. 2 connecting side plates and No. 2 connecting parts are set at both ends of the main body of the cement slab to further realize modular splicing in the longitudinal direction. This allows the entire structure to be flexibly expanded in the horizontal and vertical directions, adapting to various installation scenarios and improving construction efficiency and application flexibility.

[0020] 2. A locking mechanism consisting of a movable plate, a plug rod, and a spring is installed inside the No. 1 and No. 2 connectors. After the connector is inserted into the corresponding connecting slot, the plug rod can automatically insert into the positioning hole under the action of the spring, thereby realizing the secondary locking of the splicing structure. This significantly enhances the stability and shear resistance of the connection parts, avoids the problem of loosening and falling off due to external force or vibration, and greatly improves the safety and durability of the overall structure.

[0021] 3. In summary, this utility model achieves multi-directional expansion connection of fiber cement flat panels by setting up horizontal and vertical splicing structures. The splicing is firm and stable, effectively avoiding problems such as misalignment and cracking. At the same time, the secondary locking mechanism with the cooperation of the insertion rod and positioning hole further improves the connection strength and vibration resistance, significantly improving installation efficiency, structural safety and convenience of later maintenance.

[0030] Please see Figure 1-4 This utility model provides a technical solution:

[0031] A spliced ​​fiber cement flat plate includes a cement flat plate body 1. A first connecting side plate 2 is fixedly connected to the right end of the cement flat plate body 1. A first connecting piece 3, which mates with the first connecting side plate 2, is fixedly connected to the left end of the cement flat plate body 1. A second connecting side plate 5 is fixedly connected to the lower end of the cement flat plate body 1, and the right part of the second connecting side plate 5 extends to the lower end of the first connecting side plate 2. A second connecting piece 4, which mates with the second connecting side plate 5, is fixedly connected to the upper end of the cement flat plate body 1.

[0032] In this embodiment, the first connecting side plate 2 has a first connecting groove 6 adapted to the first connecting member 3, and a first protrusion 7 is fixedly connected in the first connecting groove 6. The second connecting side plate 5 has a second connecting groove 8 adapted to the second connecting member 4 in the middle, and a second protrusion 9 is fixedly connected in the second connecting groove 8, and the size of the second protrusion 9 is the same as the size of the first protrusion 7. The upper and lower groove walls of the first connecting groove 6 both have sliding grooves 61, and the upper and lower groove walls of the first connecting groove 6 both have four positioning holes 62, and two of them are positioning... Holes 62 are arranged symmetrically on the front and rear sides of the slide groove 61; the internal structure of the second connecting groove 8 is the same as that of the first connecting groove 6; the second connecting piece 4 includes a connecting block 41, which is fixedly installed in the middle of the upper end of the cement slab body 1. Both ends of the connecting block 41 are integrally formed with slide strips 42 that are adapted to the slide groove 61 in the second connecting groove 8. The upper end of the connecting block 41 has a groove 49 that is adapted to the second protrusion 9. The connecting block 41 is fixedly engaged in the second connecting groove 8 through the groove 49.

[0033] The above solution achieves rapid lateral splicing between adjacent cement slabs by setting No. 1 connecting side plates 2 and No. 1 connecting parts 3 at the left and right ends of the cement slab body 1. The splicing process is simple and the connection is tight. At the same time, No. 2 connecting side plates 5 and No. 2 connecting parts 4 are set at the upper and lower ends of the cement slab body 1 to further realize modular splicing in the longitudinal direction. This allows the entire structure to be flexibly expanded in the horizontal and vertical directions, adapting to various installation scenarios and improving construction efficiency and application flexibility.

[0034] In this embodiment, two movable cavities 43 are symmetrically opened inside the connecting block 41. Movable plates 44 are slidably connected to each of the two movable cavities 43. Four insertion rods 45 that are adapted to the positioning holes 62 in the second connecting groove 8 are fixedly connected to the side of each of the two movable plates 44 away from the opposite end. Springs 46 are fixedly connected to the end of each of the two movable plates 44 away from the insertion rods 45, and the end of the springs 46 away from the movable plates 44 is fixedly connected to the inner wall of the movable cavity 43. A guide groove 48 penetrating the front end of the connecting block 41 is opened in the front groove wall of the movable cavity 43. A pull rod 47 that is slidably connected to the guide groove 48 is fixedly connected to the front end of the movable plate 44. The structure of the first connecting piece 3 is the same as the structure of the second connecting piece 4. The connection method between the first connecting piece 3 and the first connecting side plate 2 is the same as the connection method between the second connecting piece 4 and the second connecting side plate 5.

[0035] The above solution involves setting a locking mechanism consisting of a movable plate 44, a plug rod 45, and a spring 46 inside the first connector 3 and the second connector 4. This allows the plug rod 45 to automatically insert into the positioning hole 62 under the action of the spring after the connector is inserted into the corresponding connecting slot, thereby achieving secondary locking of the splicing structure. This significantly enhances the stability and shear resistance of the connection parts, avoids loosening and falling off due to external forces or vibrations, and greatly improves the safety and durability of the overall structure.

[0036] It should be noted that this utility model is a splicing fiber cement flat plate. During use, firstly, when splicing multiple cement flat plate bodies 1, the user can insert the first connector 3 of one cement flat plate body 1 into the first connecting groove 6 inside the first connecting side plate 2 of an adjacent cement flat plate body 1, thus achieving horizontal splicing. Similarly, the second connector 4 of one cement flat plate body 1 is inserted into the second connecting groove 8 inside the second connecting side plate 5 of an adjacent cement flat plate body 1 to achieve vertical splicing. Next, during insertion, pulling the pull rod 47 moves the movable plate 44 into the movable cavity 43, compressing the spring 46 and causing the insertion rod 45 to retract into the movable cavity 43, allowing for smooth insertion of the first connector 3 or the second connector 4. Then, the grooves 49 on the first connector 3 and the second connector 4 match the first protrusion 7 or the second protrusion 9 in the corresponding connecting groove, forming a preliminary connection. Positioning and limiting prevent the connector from sliding out before locking, ensuring the stability of the connection process. Subsequently, after the connector 41 is fully inserted into the corresponding connecting groove, the spring 46 rebounds and pushes the movable plate 44 after the pull rod is released, causing the insertion rod 45 to extend and insert into the positioning hole 62 on the inner wall of the connecting groove, thereby achieving a firm lock. At the same time, since the sliding groove 61 is set on the upper and lower groove walls of the connecting groove, the sliding strip 42 on the connector can slide along the sliding groove and be inserted, further guiding the connector to accurately enter the connecting groove and providing guidance and support, avoiding offset or jamming during installation. In addition, the structure of the first connector 3 is the same as that of the second connector 4, and its connection method with the first connecting side plate 2 is also consistent with the connection method of the second connector 4 and the second connecting side plate 5. Therefore, whether it is horizontal or vertical splicing, a uniform connection strength and operation method can be guaranteed, improving the compatibility and standardization of the overall system.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
