Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite panel technology, specifically to a double-steel-faced floating bead fire-resistant and heat-insulating composite panel. Background Technology
[0002] Cenospheres are hollow, glassy particles with tiny diameters and smooth surfaces. They possess excellent properties such as low density, low thermal conductivity, high temperature resistance (up to 1300℃ or higher), and good chemical stability, making them an ideal raw material for preparing lightweight refractory and heat-insulating materials. Refractory and heat-insulating boards made primarily of cenospheres are widely used in high-temperature equipment and fire-resistant building structures in metallurgy, chemical, power, and building materials industries due to their lightweight, high strength, fire resistance, and heat insulation properties.
[0003] However, traditional cenosphere refractory insulation boards have the following technical problems in practical applications: When installing existing composite boards, it is usually necessary to splice multiple composite boards together first, and then use bolts to fix multiple composite boards. During the fixing process, corresponding installation tools are usually required to install the composite boards. The installation process is cumbersome, which can easily increase the installation time and affect the installation efficiency. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a double-sided steel-faced beaded fire-resistant and heat-insulating composite panel, thereby solving the problems mentioned in the background art, such as the cumbersome installation process and long installation time of multiple composite panels, which lead to low installation efficiency.
[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a double-sided steel-faced beaded fire-resistant and heat-insulating composite board, comprising multiple single panels spliced sequentially, with multiple limiting members on one side of each single panel and limiting grooves corresponding to the limiting members on the other side of each single panel. The top and bottom of the limiting grooves are provided with slots. Each limiting member includes a limiting frame, which is divided into two spring cavities by a partition. Trapezoidal limiting blocks are connected to the spring cavities by multiple springs. During the insertion of the limiting member into the limiting groove, the two limiting blocks move relative to each other.
[0006] Furthermore, the single plate includes a beaded plate and steel plates disposed on both surfaces of the beaded plate.
[0007] Furthermore, each of the limiting blocks is equipped with a plug rod, the limiting frame has a corresponding insertion hole, and the single board has a limiting hole corresponding to the insertion hole.
[0008] Furthermore, the limiting hole and the insertion hole are provided with plugs, and the plugs are provided with handles.
[0009] Furthermore, each of the limiting blocks has a guide hole in the middle, and a guide rod is provided in the guide hole. One end of the guide rod passes through a spring and is connected to the partition.
[0010] Furthermore, one side of the single board is provided with a splicing groove, and multiple limiting grooves are evenly opened in the splicing groove. The other side of the single board is provided with a splicing protrusion that matches the splicing groove, and the limiting component is set on the splicing protrusion.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts a double steel-faced sandwich design, which can significantly improve the overall bending resistance of the single board; through the combined use of limiting blocks, limiting frames and springs, the limiting frame is quickly fixed in the limiting groove, realizing the rapid splicing of two single boards and improving installation efficiency; through the use of insertion rods and tools such as cable ties, the purpose of rapid disassembly can be achieved.

Detailed Implementation
[0019] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] like Figure 1-6As shown, this utility model provides a double-sided steel-faced beaded fire-resistant and heat-insulating composite board, including multiple single boards 1 spliced together in sequence. One side of the single board 1 is provided with multiple limiting members 2, and the other side of the single board 1 is provided with a limiting groove 3 corresponding to the limiting member 2. The top and bottom of the limiting groove 3 are provided with slots 4. The limiting member 2 includes a limiting frame 21. The limiting frame 21 is divided into two spring cavities 23 by a partition 22. Trapezoidal limiting blocks 25 are connected to the spring cavities 23 by multiple springs 24. The limiting blocks 25 are slidably installed in the spring cavities 23. During the process of the limiting member 2 being inserted into the limiting groove 3, the two limiting blocks 25 move relative to each other.
[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, multiple single boards 1 are connected end to end by splicing. During splicing, one single board 1 is driven to move towards another single board 1, that is, the limiting member 2 moves towards the limiting groove 3. During the process of the limiting member 2 being inserted into the limiting groove 3, the inclined surface of the limiting block 25 contacts the limiting groove 3. Under the compression of the limiting groove 3, the two limiting blocks 25 move relative to each other, causing the limiting blocks 25 to retract into the spring cavity 23. As the limiting blocks 25 enter, the two limiting blocks 25 will move back and forth under the elastic action of the spring 24, so that the tail of the limiting block 25 enters the slot 4, which can effectively prevent the limiting member 2 from slipping out of the limiting groove 3. The installation process reduces the amount of bolts used, shortens the installation time, and improves the installation efficiency.
[0022] The single plate 1 includes a beaded plate 11 and a steel plate 12 disposed on both surfaces of the beaded plate 11.
[0023] like Figure 4 As shown, this embodiment employs a double-steel-faced sandwich design. The steel plate 12 and the perlite plate 11 are fixed together by welded studs and epoxy resin bonding, improving the interface bonding strength and effectively avoiding the risk of delamination. The symmetrically distributed steel plate 12 and perlite plate 11 significantly improve the overall bending stiffness and reduce the deformation of the steel surface under high temperature or impact loads. An acrylic-modified chloroprene resin or aerogel composite coating is sprayed on the outer side of the steel plate 12 to improve high temperature resistance and impact resistance. For the material ratio of the perlite plate 11, a ratio of 40-60 parts perlite, 50-80 parts aluminate cement, and 2-4 parts chopped ceramic fibers is selected, balancing lightweight density ≤650kg / m³ and flexural strength ≥4MPa, while also achieving a fire resistance limit ≥3 hours. Gradient foaming technology controls the internal porosity to 20-50% by volume, reduces the thermal conductivity to ≤0.08W / m·K, and avoids the risk of fracture caused by stress concentration. A staged gradient drying process of 50℃→100℃→150℃ is adopted to shorten the drying cycle to 24 hours, while avoiding cracking caused by rapid water loss.
[0024] Each of the limiting blocks 25 is equipped with a plug rod 26, the limiting frame 21 is provided with a plug hole 27 corresponding to the plug rod 26, and the single board 1 is provided with a limiting hole 5 corresponding to the plug hole 27.
[0025] like Figure 5 and Figure 6 As shown, the insertion rod 26 is inserted into the bottom of the limiting block 25. When it is necessary to disassemble the assembled composite board, the insertion rod 26 can be pulled out. Under the action of the insertion hole 27 and the limiting hole 5, the insertion rod 26 is exposed, making it convenient for construction personnel to control the insertion rod 26. Specifically, the insertion rod 26 is pulled out part of the way to expose it. The construction personnel then drive the two insertion rods 26 to move relative to each other, causing the two limiting blocks 25 to move relative to each other, so that the limiting blocks 25 are disengaged from the slot 4. Then, the single board 1 is driven to move, and the limiting part 2 is disengaged from the limiting groove 3, thus completing the disassembly.
[0026] The limiting hole 5 and the insertion hole 27 are provided with a plug 6, and the plug 6 is provided with a handle 7.
[0027] like Figure 5 As shown, the limiting hole 5 and the insertion hole 27 are blocked by the plug 6. The plug 6 is made of fire-resistant and heat-insulating material, which can effectively improve the heat insulation effect. The handle 7 makes it easy to pull out the plug 6.
[0028] Each of the limiting blocks 25 has a guide hole in the middle, and a guide rod 28 is provided in the guide hole. One end of the guide rod 28 passes through the spring 24 and is connected to the partition plate 22.
[0029] like Figure 6 As shown, the guide rod 28 guides the lifting and lowering of the limit block 25.
[0030] The single board 1 has a splicing groove 8 on one side, and multiple limiting grooves 3 are evenly opened in the splicing groove 8. The single board 1 has a splicing protrusion 9 that matches the splicing groove 8 on the other side, and the limiting member 2 is set on the splicing protrusion 9.
[0031] like Figure 2 As shown, the splicing protrusion 9 is inserted into the splicing groove 8, which, together with the limiting groove 3 and the limiting part 2, increases the heat transfer path. The concave-convex structure reduces the splicing gap and solves the problem of poor heat insulation effect caused by the splicing gap during splicing.
[0032] Operating principle: During installation, push one panel 1 towards another panel 1, so that the splicing protrusion is inserted into the splicing groove 8. During the pushing process, under the elastic action of the spring 24, the two limiting pieces 2 are squeezed into the limiting groove 3 and retracted into the spring cavity 23. As the limiting piece 2 is inserted into the limiting groove 3, the inclined part of the limiting block 25 enters the slot 4, which can effectively prevent the limiting piece 2 from slipping out of the limiting groove 3. Finally, insert the plug 6 into the limiting hole 5 and the insertion 27 to complete the splicing. During disassembly, remove the plug 6 and pull out the insertion rod 26 a part. The construction personnel then drive the two insertion rods 26 to move relative to each other, causing the two limiting blocks 25 to move relative to each other, so that the limiting blocks 25 are disengaged from the slot 4. Then, use tools such as cable ties to tie and fix the two limiting blocks 25 of the multiple limiting pieces 2 together. Then drive one panel 1 away from each other to achieve disassembly.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
