Description

Technical Field

[0001] This utility model relates to the field of fire-resistant building material board technology, specifically to spliced ​​fire-resistant building material board. Background Technology

[0002] Traditional fire-resistant building material boards are mostly fixed and spliced ​​using bolts or welding, which has the following problems:

[0003] Installation is complex: it requires external tools (such as wrenches and welding equipment), which is time-consuming and labor-intensive, and is especially inefficient in confined spaces or at heights.

[0004] Insufficient structural stability: Bolts are prone to loosening due to thermal expansion or vibration, and welding may damage the fire-resistant layer of the plate, reducing the overall fire resistance;

[0005] Maintenance difficulties: partial damage requires complete disassembly and replacement, resulting in high costs;

[0006] Low connection strength: Linear connection methods are prone to stress concentration points, making them easy to break when subjected to external forces.

[0007] While existing technologies feature modular splicing designs, they largely rely on snap-fit ​​or simple plug-in connections, making it difficult to balance fire resistance and mechanical strength. Therefore, there is an urgent need for a spliced ​​fire-resistant building material panel that requires no complex tools, can be quickly assembled, and possesses high stability. Utility Model Content

[0008] In view of the shortcomings of the existing technology, this utility model provides a spliced ​​fire-resistant building material board, which solves the problems mentioned above.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a splicing fire-resistant building material board, comprising multiple splicing units, which are connected by a connecting mechanism. Each splicing unit includes a fire-resistant board body, and the inner cavity of the fire-resistant board body is provided with two cylindrical grooves for the connecting mechanism to pass through. The two cylindrical grooves are arranged in a cross shape in the inner cavity of the fire-resistant board body.

[0010] The connecting mechanism includes a connecting rod and a sealing rod inserted into the inner cavity of the refractory board body. The connecting rod has an upper semi-circular rod at its top and a lower semi-circular rod at its bottom. Two connecting rods are inserted into the cylindrical grooves connecting the upper and lower refractory board bodies, and the two connecting rods face each other. The lower semi-circular rod of the upper connecting rod and the upper semi-circular rod of the lower connecting rod combine to form a complete cylindrical rod. In use, the refractory board body is first fixed at the bottom. Then, the two connecting rods are inserted into the cylindrical grooves on both sides of the refractory board body, forming a cross shape, with the two lower semi-circular rods fitting together. The cylindrical groove of the upper refractory board body is then inserted above the upper semi-circular rod at the top of the connecting rod, and the connecting rod is then inserted into the upper... The refractory board body is assembled with the lower and upper semicircular rods of the connecting rod in contact. At this point, the guide slope of the positioning pin is compressed and retracts into the inner groove until the upper and lower semicircular rods are completely in contact. The positioning pin is then flush with the positioning groove. The return spring pushes the positioning pin out and inserts it into the positioning groove for positioning. This assembly is repeated until the top and leftmost refractory board bodies are connected by inserting the sealing rod with an interference fit. This allows for the rapid assembly of multiple refractory board bodies without the need for bolts. The cross-shaped cross axis formed by the intersecting connecting rods greatly enhances the connection strength. Furthermore, the interlacing of the lower and upper semicircular rods between the upper and lower connecting rods forms a shear structure, making the overall structure more stable and distributing the stress more evenly.

[0011] As a further embodiment of this utility model: the connecting rod is a cylinder that is interference-fitted with the cylindrical groove, and both the upper and lower semi-circular rods are semi-cylinders.

[0012] As a further embodiment of this utility model: the inner cavity of the upper semi-circular rod is provided with an inner groove, and the inner cavity of the inner groove is fixedly connected to a positioning pin by a reset spring; a positioning groove adapted to the positioning pin is provided on one side of the lower semi-circular rod, and a guide slope is provided on the surface of the positioning pin.

[0013] As a further embodiment of this utility model: the sealing rod has the same shape as the lower semi-circular rod, and its surface is also provided with a positioning groove that matches the positioning pin. The sealing rod is used to seal the cylindrical groove on the top of the plate.

[0014] As a further embodiment of this utility model: a plug-in rod is fixedly connected to the bottom of the refractory board body, and a plug-in groove adapted to the plug-in rod is opened on the top of the refractory board body.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] Quick tool-free installation: The connecting rod is interference-fitted with the cylindrical groove and automatically locked by the locating pin, requiring no bolts or welding;

[0017] High-strength shear-resistant structures:

[0018] The cross-shaped connecting rods form a multi-directional force axis, dispersing stress.

[0019] The upper and lower semicircular rods interlock to enhance shear resistance;

[0020] Stable sealing performance:

[0021] The locating pin (spring return) is precisely locked to the locating groove to prevent disengagement;

[0022] The dual positioning of the connector rod and connector slot reduces material displacement.

[0023] The sealing rod seals the groove to prevent the fire from spreading along the connection point;

[0024] Modular maintenance: Damaged individual panels can be disassembled and replaced individually, reducing costs;

[0025] Fire resistance optimization: The connection structure is embedded in the plate body, reducing exposed weak points and ensuring the overall fire resistance integrity. Attached Figure Description

[0034] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0035] Please see Figure 1-7 This utility model provides a technical solution: a splicing fire-resistant building material board, including multiple splicing units, which are connected by a connecting mechanism. The splicing unit includes a fire-resistant board body 1. The inner cavity of the fire-resistant board body 1 is provided with two cylindrical grooves 4 for the connecting mechanism to pass through. The two cylindrical grooves 4 are arranged in a cross shape in the inner cavity of the fire-resistant board body 1.

[0036] The connecting mechanism includes a connecting rod 2 and a sealing rod 3 inserted into the inner cavity of the refractory board body 1. The top of the connecting rod 2 has an upper semi-circular rod 6, and the bottom of the connecting rod 2 has a lower semi-circular rod 5. Two connecting rods 2 are inserted into the cylindrical groove 4 connecting the upper and lower refractory board bodies 1, and the two connecting rods 2 are positioned facing each other. The lower semi-circular rod 5 of the upper connecting rod 2 and the upper semi-circular rod 6 of the lower connecting rod 2 combine to form a complete circular rod. In use, the refractory board body 1 is first fixed at the bottom, and then the two connecting rods 2 are respectively inserted into the cylindrical grooves 4 on both sides of the refractory board body 1. At this time, the two connecting rods 2 form a cross shape, and the two lower semi-circular rods 5 are in contact with each other. Then, the cylindrical groove 4 of the upper refractory board body 1 is inserted above the upper semi-circular rod 6 at the top of the connecting rod 2, and then the connecting rod 2 is inserted into the upper refractory board. The refractory body 1 is assembled with the lower semicircular rod 5 of the connecting rod 2 in contact with the upper semicircular rod 6. At this time, the guide slope 11 of the positioning pin 9 is squeezed and retracts into the inner groove 7 until the upper semicircular rod 6 and the lower semicircular rod 5 are completely in contact. At this time, the positioning pin 9 is flush with the positioning groove 10. Then, the return spring 8 pushes the positioning pin 9 out and inserts it into the positioning groove 10 for positioning. The assembly is repeated until the uppermost and leftmost refractory body 1 are connected by the sealing rod 3 under interference fit. Multiple refractory body 1 can be assembled quickly without bolts. Moreover, the cross-shaped cross axis formed by the connecting rods 2 greatly enhances the connection strength. In addition, the upper and lower connecting rods 2 are intersected by the lower semicircular rod 5 and the upper semicircular rod 6 to form a shear structure, making the overall structure more stable and the force more dispersed.

[0037] The connecting rod 2 is a cylinder that is press-fitted with the cylindrical groove 4, and both the upper semi-circular rod 6 and the lower semi-circular rod 5 are semi-cylinders.

[0038] The upper semi-circular rod 6 has an inner groove 7, and the inner cavity of the inner groove 7 is fixedly connected to the positioning pin 9 by a return spring 8. The lower semi-circular rod 5 has a positioning groove 10 that matches the positioning pin 9 on one side, and the surface of the positioning pin 9 has a guide slope 11.

[0039] The sealing rod 3 has the same shape as the lower semi-circular rod 5, and its surface is also provided with a positioning groove 10 that matches the positioning pin 9. The sealing rod 3 is used to seal the cylindrical groove 4 on the top of the plate.

[0040] The bottom of the refractory board body 1 is fixedly connected with a plug rod 13, and the top of the refractory board body 1 is provided with a plug groove 12 that is compatible with the plug rod 13.

[0041] In use, this utility model employs the following collaborative mechanisms for its connecting mechanism: Cross-shaped connecting rods: Two connecting rods are inserted into the cylindrical groove of the lower layer of the plate in a cross shape, forming a three-dimensional support frame and enhancing lateral and longitudinal compressive strength; Semi-circular rod engagement: The upper layer of the plate engages with the lower semi-circular rod 5 of the lower connecting rod via the upper semi-circular rod 6 of the connecting rod, forming a complete circular rod that evenly transmits load using the arc surface; Self-locking process of the positioning pin: During installation, the upper layer of the plate is pressed down, causing the guide slope 11 of the positioning pin 9 to be squeezed and compressed back into the inner groove 7; When the semi-circular rods are fully engaged, the return spring 8 pushes the positioning pin out, inserting it into the positioning groove 10 of the lower semi-circular rod, achieving self-locking; Sealing design: The cylindrical groove of the outermost plate is inserted into the sealing rod 3, whose positioning groove cooperates with the positioning pin to seal the groove and prevent fire penetration; Insertion auxiliary positioning: The insertion rod 13 at the bottom of the plate is embedded into the insertion groove 12 at the top of the adjacent plate, further limiting displacement and improving splicing accuracy and airtightness. Overall effect: Through mechanical interlocking, spring self-locking and plug-in sealing, the fire-resistant building material board achieves efficient splicing and stable load-bearing, and is suitable for harsh environments such as high temperature and vibration.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
