Description

Technical Field

[0001] This utility model relates to the field of building integrated application technology, specifically a fireproof decorative panel. Background Technology

[0002] Building integration refers to the deep integration of specific functional systems (such as energy, decoration, equipment, and ecological technologies) with the entire lifecycle of a building, including planning, design, construction, and operation and maintenance, rather than simply adding them later. The ultimate goal is to achieve synergistic optimization of building function, aesthetics, performance, and benefits. Its core is to break down the disconnect between the main building and its supplementary systems, making each functional module an organic component of the building itself.

[0003] According to announcement number CN220580389U, a fireproof decorative panel is disclosed. This technology discloses "a magnesium oxide substrate layer and an HPL fireproof board layer, wherein the HPL fireproof board layer has two layers, located on the upper and lower surfaces of the magnesium oxide substrate layer. The magnesium oxide substrate layer has multiple fine pores inside, and the fine pores are filled with glue. The magnesium oxide substrate layer is sealed around its perimeter, etc., which provides better stability. At the same time, the material has advantages such as light weight, high temperature resistance, good thermal stability, low thermal conductivity, good resistance to mechanical vibration, small thermal expansion, and good thermal insulation performance. The panel is environmentally friendly, lightweight (which helps reduce the building load), high strength, sound insulation, and has a long service life." However, existing technologies still have the following problems: Existing fire-resistant decorative panels are mostly single flat structures or simple composite structures without any staggered reinforcement design, resulting in weak impact and deformation resistance. The interlayers are mostly fixed by a single bonding method, which is insufficient. After long-term use, the interlayers are prone to loosening and separation, resulting in poor overall structural stability.

[0004] Secondly, most fireproof decorative panels have a single-layer or simple composite fireproof layer, with insufficient thickness of the flame-retardant core layer, making them easy for flames to penetrate and resulting in limited fireproof effect. Most of them also lack a dedicated moisture-proof structure, making them susceptible to moisture intrusion, which can lead to internal corrosion, efflorescence, or deformation, resulting in a short service life in humid environments.

[0005] To address the aforementioned problems, the inventors proposed a fire-resistant decorative panel to solve them. Utility Model Content

[0006] To address the problems of fireproof decorative panels lacking reinforced design with no staggered joints, resulting in weak impact and deformation resistance, simple structure, insufficient thickness of the flame-retardant core layer, easy flame penetration, and limited fireproof effect, the purpose of this utility model is to provide a fireproof decorative panel.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fireproof decorative panel, comprising four substrates, the four substrates being divided into two groups and distributed vertically in a corresponding manner, the upper and lower groups of substrates being arranged in a mirror structure; each substrate has a plurality of external recesses on its outer end face and a plurality of internal recesses on its inner end face, the external recesses being arranged at equal intervals along the length direction on the outer end face of the substrate, the internal recesses being arranged at equal intervals along the length direction on the inner end face of the substrate, and the external and internal recesses on the upper and lower sides of a single substrate being staggered in the projection direction to improve the structural stability of the substrate; on the opposing end faces of the two upper and lower substrates, a main adhesive layer and two auxiliary adhesive layers are respectively provided, and a fireproof composite layer is sandwiched between the upper and lower substrates, the upper and lower end faces of the fireproof composite layer being tightly bonded and fixed to the corresponding main adhesive layer and auxiliary adhesive layer.

[0008] Preferably, the upper and lower substrates and the fireproof composite layer located between them are each fixedly connected to a connecting seat at both ends. The height of the upper and lower ends of the connecting seat is consistent with the height of the outer end of the substrate on both sides of the connecting seat, ensuring that the end faces are flush when multiple fireproof decorative panels are spliced. Two positioning blocks are fixedly installed on the end of one of the connecting seats away from the substrate, and two positioning grooves adapted to the positioning blocks are opened on the end of the other connecting seat away from the substrate. A connecting plate is provided on the same side end of the two connecting seats. One end of the connecting plate is fixedly connected to one of the connecting seats, and the end of the other connecting seat is provided with a connecting groove adapted to the connecting plate. A fixing bolt is threaded through the connecting plate and the corresponding connecting seat to realize the fixed connection of the two connecting seats. The inner wall of the connecting groove and the end of the connecting plate inserted into the connecting groove are both provided with threaded holes adapted to the threads of the fixing bolts to ensure that the fixing bolts can be stably inserted and fixed.

[0009] Preferably, the fireproof composite layer is a structure formed by multiple functional materials. The fireproof composite layer includes a surface fireproof board, a flame-retardant core layer, and a bottom moisture-proof board. The upper end face of the flame-retardant core layer is fixedly connected to the lower end face of the surface fireproof board, and the lower end face of the flame-retardant core layer is fixedly connected to the upper end face of the bottom moisture-proof board. The three together constitute the overall structure of the fireproof composite layer. The thickness parameter of the flame-retardant core layer is 1.8 times the sum of the thickness of the surface fireproof board and the bottom moisture-proof board to ensure that the fireproof performance of the flame-retardant core layer is fully utilized. The surface fireproof board is made of rock wool fireproof board, and the bottom moisture-proof board is made of polyethylene moisture-proof board. The two materials respectively meet the functional requirements of fireproof and moisture-proof.

[0010] Installation method: Before installation, ensure the substrate is flat and dry, and clean away dust, debris, and protrusions. Also, check that the base plate, connectors, fire-resistant composite layer, positioning blocks, and fixing bolts are undamaged or deformed. Next, attach the first fire-resistant decorative panel to the designated position on the substrate, adjusting the angle and height until the edges align with the installation baseline and temporarily securing it. Then, take the subsequent decorative panels and align them with the positioning slots on the connectors to complete initial positioning. Push the panels to insert the connecting plate into the corresponding slots, and then tighten the fixing bolts through the threaded holes to achieve a secure connection. Repeat this process until all fire-resistant decorative panels are installed. Finally, check all joints for gaps or looseness, ensuring the fire-resistant decorative panels are not displaced and the fixing bolts are tightened to guarantee installation quality. Instructions for use: In daily use, this fireproof decorative panel can serve as a decorative and functional layer for walls, cabinets, etc. Sharp objects should be avoided from impacting the substrate surface to prevent damage to the outer and inner recesses, which could affect stability. Prolonged exposure to water should also be avoided to prevent moisture penetration. In the event of a fire, the surface fireproof board will block the spread of flames, and the flame-retardant core layer will further inhibit fire penetration, buying time for safety. In humid environments such as kitchens and bathrooms, the bottom moisture-proof board can isolate moisture and protect the internal structure. For maintenance, regularly wipe away surface dust with a dry, soft cloth. For stains, use a damp cloth with neutral detergent to gently wipe and then dry. Check the fixing bolts at the joints every six months; if loose, tighten them promptly to maintain structural stability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model improves the structural strength of the substrate by using a staggered distribution design of the outer and inner recesses, making it less prone to deformation due to external forces. At the same time, the main adhesive layer and the auxiliary adhesive layer work together to achieve a stable connection between the substrate and the fireproof composite layer, making the core functional layer structure less prone to loosening. The overall device can maintain good structural stability during use.

[0012] 2. This utility model adopts a multi-layer functional material composite structure for the fireproof composite layer. The surface fireproof board and the flame-retardant core layer work together to effectively block the spread of flames and inhibit the penetration of fire, resulting in a significant fireproof effect. The bottom moisture-proof board can isolate external moisture, prevent moisture from damaging the internal structure of the decorative panel, and extend the service life of the decorative panel. It is suitable for humid environments or scenarios with moisture-proof requirements. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Example: Figure 1-4As shown, this utility model provides a fireproof decorative panel, including four substrates 1. The four substrates 1 are divided into two groups and are distributed vertically and horizontally. The upper and lower groups of substrates 1 are arranged in a mirror structure. Each substrate 1 has a plurality of external recesses 11 on its outer end face and a plurality of internal recesses 12 on its inner end face. The external recesses 11 are arranged at equal intervals along the length direction on the outer end face of the substrate 1, and the internal recesses 12 are arranged at equal intervals along the length direction on the inner end face of the substrate 1. The external recesses 11 and internal recesses 12 on the upper and lower sides of a single substrate 1 are staggered in the projection direction to improve the structural stability of the substrate 1. On the opposing end faces of the two upper and lower substrates 1, a main adhesive layer 13 and two auxiliary adhesive layers 14 are respectively provided. A fireproof composite layer 3 is sandwiched between the upper and lower substrates 1. The upper and lower end faces of the fireproof composite layer 3 are tightly bonded and fixed to the corresponding main adhesive layer 13 and auxiliary adhesive layer 14. The device includes four substrates 1, which are divided into two groups and are distributed in a mirror structure. The outer recesses 11 on the outer end face of each substrate 1 are arranged at equal intervals along the length direction, and the inner recesses 12 on the inner end face are also arranged at equal intervals. Furthermore, the outer recesses 11 and inner recesses 12 on the upper and lower sides of a single substrate 1 are staggered in the projection direction. This structural design can enhance the structural stability of the substrate 1 itself and prevent it from easily deforming under stress. On the opposing end faces of the two substrates 1, a main adhesive layer 13 and two auxiliary adhesive layers 14 are respectively provided. The fireproof composite layer 3 is sandwiched between the upper and lower substrates 1, and its upper and lower end faces are tightly bonded to the corresponding main adhesive layer 13 and auxiliary adhesive layer 14. Through the main adhesive force of the main adhesive layer 13 and the auxiliary fixing effect of the auxiliary adhesive layer 14, a stable connection between the substrate 1 and the fireproof composite layer 3 is achieved, forming a core functional layer structure.

[0021] The upper and lower substrates 1 and the fireproof composite layer 3 located between them are both fixedly connected to connecting seats 2 at both ends. The height of the upper and lower ends of the connecting seats 2 is consistent with the height of the outward-facing ends of the substrates 1 on both sides of the connecting seats 2, ensuring that the end faces are flush when multiple fireproof decorative panels are spliced. Two positioning blocks 21 are fixedly installed on the end of one connecting seat 2 away from the substrate 1, and two positioning grooves 22 adapted to the positioning blocks 21 are opened on the end of the other connecting seat 2 away from the substrate 1. A connecting plate 23 is provided on the same side end of the two connecting seats 2. One end of the connecting plate 23 is fixedly connected to one of the connecting seats 2, and the other connecting seat 2 is fixedly connected to the other connecting seat 2. The end of 2 is provided with a connecting groove 24 that is adapted to the connecting plate 23, and the connecting plate 23 and the corresponding connecting seat 2 are connected by a fixing bolt 25 through threaded engagement to realize the fixed connection of the two connecting seats 2. The inner wall of the connecting groove 24 and the end of the connecting plate 23 inserted into the connecting groove 24 are provided with threaded holes that are adapted to the threads of the fixing bolt 25 to ensure that the fixing bolt 25 can be stably inserted and fixed. The upper and lower base plates 1 and the fireproof composite layer 3 in the middle are fixedly connected to the two ends of the base plates 1, and the height of the upper and lower ends of the connecting seat 2 is consistent with the height of the outward end of the base plates 1 on both sides, providing a basis for the end face to be flush when multiple decorative panels are spliced ​​later. When multiple decorative panels need to be spliced, the two positioning blocks 21 of one fireproof decorative panel connector 2 facing away from the base plate 1 can be inserted into the two positioning grooves 22 of the corresponding connector 2 of another fireproof decorative panel facing away from the base plate 1 to achieve initial positioning. At the same time, the connecting plate 23 (one end of which is fixed to one of the connector 2) at the same end of the two connectors 2 can be inserted into the connecting groove 24 at the end of the other connector 2. Then, the fixing bolt 25 is threaded through the threaded hole of the connecting plate 23 and the inner wall of the connecting groove 24 to finally complete the fixing of the two connectors 2, thereby achieving stable splicing of multiple fireproof decorative panels.

[0022] The fire-resistant composite layer 3 is a structure formed by multiple functional materials. It includes a surface fireproof board 31, a flame-retardant core layer 32, and a bottom moisture-proof board 33. The upper surface of the flame-retardant core layer 32 is fixedly connected to the lower surface of the surface fireproof board 31, and the lower surface of the flame-retardant core layer 32 is fixedly connected to the upper surface of the bottom moisture-proof board 33. These three components together constitute the overall structure of the fire-resistant composite layer 3. The thickness of the flame-retardant core layer 32 is 1.8 times the sum of the thicknesses of the surface fireproof board 31 and the bottom moisture-proof board 33, to ensure that the fire-retardant performance of the core layer 32 is fully utilized. The fireproof board 31 is made of rock wool fireproof board, and the bottom moisture-proof board 33 is made of polyethylene moisture-proof board. The two materials respectively meet the functional requirements of fire resistance and moisture resistance. The fireproof composite layer 3 is formed by the combination of the surface fireproof board 31, the flame-retardant core layer 32 and the bottom moisture-proof board 33. The upper end of the flame-retardant core layer 32 is fixed to the lower end of the surface fireproof board 31, and the lower end is fixed to the upper end of the bottom moisture-proof board 33. The thickness of the flame-retardant core layer 32 is 1.8 times the sum of the thicknesses of the surface fireproof board 31 and the bottom moisture-proof board 33, ensuring that the flame-retardant core layer 32 can fully play its core fire-resistant role. When a fire occurs, the surface fireproof board 31 (rock wool fireproof board) first blocks the spread of flames, the flame-retardant core layer 32 further inhibits the penetration of fire, and at the same time, the bottom moisture-proof board 33 (polyethylene moisture-proof board) can isolate external moisture and prevent moisture from intruding and affecting the overall performance of the decorative panel. The three work together to achieve the dual functions of fire resistance and moisture resistance.

[0023] Working principle: The device comprises four substrates 1, divided into upper and lower groups and arranged in a mirror structure. The outer recesses 11 on the outer end face of each substrate 1 are arranged at equal intervals along the length direction, and the inner recesses 12 on the inner end face are also arranged at equal intervals. Furthermore, the outer recesses 11 and inner recesses 12 on the upper and lower sides of a single substrate 1 are staggered in the projection direction. This structural design enhances the structural stability of the substrate 1 and prevents it from easily deforming under stress. On the opposing end faces of the two upper and lower substrates 1, a main adhesive layer 13 and two auxiliary adhesive layers 14 are respectively provided. A fire-resistant composite layer 3 is sandwiched between the upper and lower substrates 1, with its upper and lower end faces tightly bonded to the corresponding main adhesive layer 13 and auxiliary adhesive layer 14. Through the main adhesive force of the main adhesive layer 13 and the auxiliary fixing effect of the auxiliary adhesive layer 14, a stable connection is achieved between the substrate 1 and the fire-resistant composite layer 3, forming a core functional layer structure. Both ends of the upper and lower base plates 1 and the middle fireproof composite layer 3 are fixedly connected to connecting seats 2. The height of the upper and lower ends of the connecting seats 2 is the same as the height of the outward-facing ends of the two base plates 1, providing a basis for the flush end faces when splicing multiple decorative panels. When multiple decorative panels need to be spliced, the two positioning blocks 21 of the connecting seat 2 of one fireproof decorative panel facing away from the base plate 1 can be inserted into the two positioning grooves 22 of the corresponding connecting seat 2 of another fireproof decorative panel facing away from the base plate 1 to achieve initial positioning. At the same time, the connecting plate 23 (one end fixed to one of the connecting seats 2) at the same end of the two connecting seats 2 can be inserted into the connecting groove 24 at the end of the other connecting seat 2. Then, the fixing bolt 25 is threaded through the threaded hole of the connecting plate 23 and the inner wall of the connecting groove 24 to finally complete the fixing of the two connecting seats 2, thereby achieving stable splicing of multiple fireproof decorative panels. The fire-resistant composite layer 3 is formed by a surface fireproof board 31, a flame-retardant core layer 32, and a bottom moisture-proof board 33. The upper surface of the flame-retardant core layer 32 is fixed to the lower surface of the surface fireproof board 31, and the lower surface of the flame-retardant core layer 32 is fixed to the upper surface of the bottom moisture-proof board 33. The thickness of the flame-retardant core layer 32 is 1.8 times the sum of the thicknesses of the surface fireproof board 31 and the bottom moisture-proof board 33, ensuring that the flame-retardant core layer 32 can fully exert its core fire-resistant function. In the event of a fire, the surface fireproof board 31 (rock wool fireproof board) first blocks the spread of flames, the flame-retardant core layer 32 further inhibits the penetration of fire, and the bottom moisture-proof board 33 (polyethylene moisture-proof board) isolates external moisture, preventing moisture intrusion from affecting the overall performance of the decorative panel. These three elements work together to achieve the dual functions of fire resistance and moisture resistance.
