Description

Technical Field

[0001] This utility model relates to the technical field of color steel sandwich panels, specifically a fireproof color steel sandwich panel. Background Technology

[0002] Color steel sandwich panels are a common building material, offering excellent flame retardancy, sound insulation, and environmental friendliness. They consist of two layers of metal panels pressed together with a middle layer of high-polymer heat-insulating core. These panels are easy to install, lightweight, environmentally friendly, and highly efficient. Furthermore, the closed-cell molecular structure used in the filling system prevents moisture condensation.

[0003] Chinese patent document CN216587107U discloses a fireproof color steel sandwich panel, which includes two layers of molded metal panels and a polymer heat-insulating inner core located between the two layers of molded metal panels. The two layers of molded metal panels are stably connected by threaded connecting screws into two nut posts. Clamping channel steel is sleeved at the edges of the two molded metal panels, and the metal panels are connected to the clamping channel steel by tightening screws and tightening nuts, thus preventing the two molded metal panels from moving away from each other. While this type of fireproof color steel sandwich panel, which is stably bonded to the two opposite sides of the polymer insulation core, can achieve the effect of preventing the molded metal panel from separating from the polymer insulation core, the following problems exist in actual use: 1. When a fire occurs during the use of existing fireproof color steel sandwich panels, due to the lack of sealing at the bottom or side gaps, and the fact that the bottom of the color steel sandwich panel is closest to the high temperature of the fire, the color steel sandwich panel is prone to continue burning from bottom to top, failing to effectively achieve fire prevention and flame retardancy, and posing a safety hazard; 2.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1:

[0020] As attached Figure 1-3As shown, this utility model provides a fireproof color steel sandwich panel, including a color steel sandwich panel body. The color steel sandwich panel body includes an upper color steel plate 1, a lower color steel plate 2, a middle core material 3, a C-shaped side plate 4, a U-shaped side plate 5, and a fireproof core frame 6. The upper color steel plate 1 is provided with wavy stripe patterns, including dark stripes and light stripes. The dark stripes are located in the middle of the upper color steel plate 1, and the light stripes are located on both sides of the dark stripes. The middle core material 3 is filled between the upper color steel plate 1 and the lower color steel plate 2. The upper side of the middle core material 3 is provided with a core material pattern with the same shape and position as the stripe patterns. The upper and lower sides of the middle core material 3 are respectively bonded and fixed to the upper color steel plate 1 and the lower color steel plate 2. The left and right ends of the middle core material 3 are respectively bonded and fixed to the U-shaped side plate 5 and the C-shaped side plate 4. The right end of the plate 4 is provided with a splicing slot 401, and the left end of the U-shaped side plate 5 is provided with a splicing head 501 that can be adapted to the splicing slot 401. The right edges of the upper color steel plate 1 and the lower color steel plate 2 are bent and bonded to the U-shaped side plate 4, and the left edges of the upper color steel plate 1 and the lower color steel plate 2 are bent and bonded to the U-shaped side plate 5. The intermediate core material 3 includes a lower insulation core layer 301 and an upper insulation core layer 302. The lower insulation core layer 301 and the upper insulation core layer 302 are bonded together. A fireproof core frame 6 is fixed inside the upper insulation core layer 302. Fireproof partitions 601 are fixed at the front and rear ends of the fireproof core frame 6, respectively, and are perpendicular to the fireproof core frame 6. The upper end of the fireproof partition 601 is close to the upper color steel plate 1, and the lower end of the fireproof partition 601 is close to the lower color steel plate 2.

[0021] The splicing clips 501 of the U-shaped side panel 5 and the splicing slots 401 of the C-shaped side panel 4 facilitate easy insertion and connection, eliminating the need for screws to fix adjacent color steel sandwich panels. The striped texture effectively increases the contact area between the upper color steel panel 1 and the middle core material 3, significantly improving their bonding strength. The striped texture also acts as a reinforcement, effectively enhancing the horizontal load-bearing capacity of the color steel sandwich panel body. By maintaining the symmetry of the front and rear structures of the fireproof core frame 6, the front and rear directions of the fireproof core frame 6 do not need to be distinguished during manufacturing, making it easier to manufacture and process. The fireproof core frame 6 front... The fire-resistant partition 601 fixed at the rear end can act as a fireproof partition for the intermediate core material 3, blocking the path of flame spread, slowing down the heat transfer rate, and reducing the melting and dripping of the intermediate core material 3 and adhesive, thus greatly reducing the fire hazard during use. In addition, the fireproof core frame 6 also forms a rectangular grid structure, which can increase the compressive strength of the color steel sandwich panel, which is conducive to further improving the overall structural strength of the color steel sandwich panel, and is conducive to the stability of handling and installation. The outer perimeter wall after installation is also more solid, flatter and more beautiful. It has the characteristics of simple structure, beautiful appearance, easy installation and safety and reliability.

[0022] Example 2:

[0023] As attached Figure 1-3 As shown, the difference between this embodiment and Embodiment 1 is that the fire baffle 601 includes a front fire baffle 6011 and a rear fire baffle 6012. The front fire baffle 6011 is fixed to the front end of the fireproof core frame 6, and the rear fire baffle 6012 is fixed to the rear end of the fireproof core frame 6. The lower insulation core layer 301 includes a lower core layer middle block, a lower core layer front block, and a lower core layer rear block. The fireproof core frame 6 sits on the upper end of the lower core layer middle block, the lower core layer front block is located at the front end of the front fire baffle 6011, and the lower core layer rear block is located at the rear end of the rear fire baffle 6012. The upper insulation core layer 301... 2 includes an upper core layer middle part 3021, an upper core layer front part 3022, and an upper core layer rear part 3023. The upper core layer front part 3022, upper core layer middle part 3021, and upper core layer rear part 3023 are connected as one unit. The upper core layer middle part 3021 is filled between the upper end of the lower core layer middle block and the upper color steel plate 1. The fireproof core frame 6 is embedded and fixed in the lower part of the upper core layer middle part 3021. The upper core layer front part 3022 is filled between the upper end of the lower core layer front block and the upper color steel plate 1. The upper core layer rear part 3023 is filled between the upper end of the lower core layer rear block and the upper color steel plate 1. By dividing the lower insulation core layer 301 into a middle block, a front block, and a rear block, the middle block can fix and support the fireproof core frame 6, while the front and rear blocks can position the fireproof core frame 6 and the fire baffle 601 in the front and rear directions. This facilitates the alignment and positioning of the fireproof core frame 6, the filling of the insulation material inside the fireproof core frame 6, and the pressing and forming of the upper insulation core layer 302 during manufacturing, thus making the forming and processing of the color steel sandwich panel easier.

[0024] Example 3:

[0025] As attached Figure 1 , 4As shown, the difference between this embodiment and embodiments 1 and 2 is that the fireproof core frame 6 includes a core frame front panel 602, a core frame rear panel 603, and several core frame horizontal tubes 604. The core frame front panel 602 and the core frame rear panel 603 are respectively provided with uniformly spaced frame tube through holes. The front part of each core frame horizontal tube 604 is fitted into the frame tube through hole of the core frame front panel 602 and welded and fixed together with the core frame front panel 602. The rear part of each core frame horizontal tube 604 is fitted into the frame tube through hole of the core frame rear panel 603 and welded and fixed together with the core frame rear panel 603. The front end of each core frame horizontal tube 604 is kept flush and welded and fixed with a front fire baffle 6011. The rear end of each core frame horizontal tube 604 is kept flush and welded and fixed with a rear fire baffle 6012. The interior of each core frame horizontal tube 604 forms an independent and closed gas cavity. The front baffle 602, the rear baffle 603, and several horizontal core frame tubes 604 are welded and fixed to form a rectangular grid structure with high structural strength. The front baffle 6011 and the rear baffle 6012 can be welded to the fireproof core frame 6 to form a whole, which further improves the structural strength of the fireproof core frame 6. They also effectively isolate the front, rear and middle parts of the intermediate core material 3, block the flame spread path, slow down the heat transfer speed, and improve the overall fire safety of this utility model. On the other hand, the front baffle 6011 and the rear baffle 6012 can also form multiple closed gas cavities inside the horizontal core frame tubes 604, which can further improve the sound insulation and heat insulation performance of this utility model.

[0026] Example 4:

[0027] As attached Figure 1 , 2As shown, the difference between this embodiment and embodiments 1-3 is that the deep stripes on the upper color steel plate 1 include deep stripe peaks 7 and deep stripe valleys 8, and the shallow stripes include shallow stripe peaks 9 and shallow stripe valleys 10. The distance between deep stripe peaks 7 and deep stripe valleys 8 is greater than the distance between shallow stripe peaks 9 and shallow stripe valleys 10. Both deep stripe valleys 8 and shallow stripe valleys 10 are flush with the surface of the upper color steel plate 1. The plane of shallow stripe peak 9 is located in the middle of the plane of deep stripe peak 7 and the plane of deep stripe valley 8. The core material texture of the intermediate core material 3 is exactly the same as the stripe texture of the upper color steel plate 1 and fits tightly. Because the striped pattern of the upper corrugated steel plate 1 is identical to and closely adheres to the core material pattern of the middle core material 3, it overcomes the problems of gaps between the corrugated steel plate and the core plate in existing corrugated steel sandwich panels, resulting in loose connections, easy delamination, and insufficient horizontal load-bearing capacity. This allows the middle core material 3 to be tightly bonded to the striped pattern of the upper corrugated steel plate 1 through its core material pattern, forming a unified whole. This significantly improves the horizontal load-bearing capacity of the corrugated steel sandwich panel, eliminating the need for wall purlins to provide auxiliary support in the middle section during installation, effectively reducing steel consumption. Furthermore, since the height of the shallow corrugated peaks 9 is between the heights of the deep corrugated peaks 7 and deep corrugated valleys 8, it overcomes the problem of uneven horizontal load-bearing capacity in existing corrugated steel sandwich panel boss structures. During manufacturing, the number and specific position of the deep corrugated peaks 7 can be rationally configured according to actual needs. This allows for adjustment of the size and transition of the striped pattern of the corrugated steel plate based on the load-bearing capacity of different parts of the corrugated steel sandwich panel, ensuring a uniform and effective improvement in the horizontal load-bearing capacity.

[0028] Example 5:

[0029] As attached Figure 1As shown, the difference between this embodiment and embodiments 1-4 is that the C-shaped side plate 4 includes a right plate body 400, an upper wing plate 402, and a lower wing plate 403. The left end of the upper wing plate 402 is integrated with the upper right side of the right plate body 400, and the left end of the lower wing plate 403 is integrated with the lower right side of the right plate body 400. A splicing groove 401 is formed between the upper wing plate 402 and the lower wing plate 403. The right edge of the upper color steel plate 1 is bent downward and covers the upper wing plate 402, and the right edge of the lower color steel plate 2 is bent upward and covers the upper wing plate 402. Upper wing plate 402; The U-shaped side plate 5 includes a left plate body 500 and a splicing clip head 501. The splicing clip head 501 includes a clip head upper plate 5011 and a clip head lower plate 5012. The right end of the clip head upper plate 5011 is integrated with the upper left side of the left plate body 500, and the right end of the clip head lower plate 5012 is integrated with the lower left side of the left plate body 500. The left edge of the upper color steel plate 1 is bent downward and covers the clip head upper plate 5011, and the left edge of the lower color steel plate 2 is bent upward and covers the clip head lower plate 5012. Because the adjacent two color steel sandwich panels are connected by interlocking C-shaped side plates 4 and L-shaped side plates, the pressure at the mating ends can further compress the left and right outer edges of the upper color steel plate 1 and the lower color steel plate 2, overcoming the problem of exposed screw heads that require screw connections in existing color steel sandwich panels. This results in a smoother and more aesthetically pleasing connection, better overall flatness of the exterior wall, and better sealing. Furthermore, the left and right ends of the upper color steel plate 1 are fitted with a top plate 5011 and an upper wing plate 402 to the upper color steel plate 1 and the C-shaped side plate 4. The U-shaped side plate 5 and the middle core material 3 are connected and reinforced. The left and right ends of the lower color steel plate 2 are reinforced by the cover clip lower plate 5012 and the lower wing plate 403 to connect and reinforce the lower color steel plate 2, U-shaped side plate 4, U-shaped side plate 5 and middle core material 3. By locking the U-shaped side plate 4 and U-shaped side plate 5, the connection strength at the connection point is improved, which overcomes the problem that the existing color steel sandwich panels need to be fixed with additional screws on both sides. This makes the connection between the upper color steel plate 1, the lower color steel plate 2 and the middle core material 3 more secure and always kept locked.

[0030] Example 6:

[0031] As attached Figure 1-3As shown, the difference between this embodiment and embodiments 1-5 is that the lower insulation core layer 301 is made of rock wool, while the upper insulation core layer 302 is made of non-renewable foam. Rock wool board is a composite material made from natural rock as the main raw material, with the addition of a certain proportion of molten rock wool fiber, plant fiber and other biomass materials, and appropriate amounts of anti-compression agents, binders, salicylic acid and other additives. Rock wool board has the characteristics of being flame-retardant, corrosion-resistant, water-resistant, not easy to age, having good thermal insulation effect, and having no odor in the surrounding environment. Non-renewable foam is a thermal insulation material made from polyurethane as the main material, with the addition of foam stabilizers, foaming agents and other additives, and then foamed through a high-temperature reaction. It has the characteristics of strong sealing, light weight, low thermal conductivity and easy processing and molding. By using rock wool board as the lower insulation core layer 301 for the inner insulation material, excellent fire resistance and sound insulation performance are achieved. Its non-combustible properties can delay the spread of fire. Non-renewable foam is selected as the upper insulation core layer 302 for the outer insulation material, making it lightweight, easy to process, and providing excellent thermal insulation. The combined use of these two materials further improves the insulation effect, sound insulation performance, and durability of this invention. When using the color steel sandwich panel, the lower insulation core layer 301 made of Class A rock wool is used on the indoor side. In the event of a fire indoors, the fire-resistant core frame 6's fire-resistant partition 601 and the rock wool work together to effectively prevent the fire from spreading outdoors.
