Description

Technical Field

[0001] This utility model relates to the field of fireproof materials technology, specifically to a fireproof board. Background Technology

[0002] Fire-resistant boards are widely used to construct fire-resistant partitions, clad steel structures, and ventilation ducts to improve the fire safety level of buildings. Currently, common fire-resistant boards on the market, such as reinforced magnesium oxide boards and gypsum boards, mostly possess excellent planar fire resistance. However, these boards are typically hard and have very poor flexibility, posing significant limitations during on-site construction.

[0003] When covering non-planar structures such as pipe bends, irregular shapes, or wall corners, traditional rigid panels are difficult to bend and adapt, forcing construction workers to perform complex cutting and splicing operations. This approach is not only inefficient and requires high levels of skill from workers, but also increases the number of seams. In a fire, these seams are precisely the weak points in fireproof integrity, allowing high-temperature flames and smoke to easily penetrate and cause the fire protection system to fail. Furthermore, current technology lacks specific fire-reinforced designs for the deformable areas of the panels. If the panels are forcibly bent, the internal fire-resistant core material may crack or develop gaps, similarly compromising fireproof continuity. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a fireproof board that can maintain high fire resistance performance and has excellent on-site installation adaptability, and can seamlessly fit complex structural surfaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fireproof board, characterized in that it comprises:

[0007] Two parallel and opposite outer panels;

[0008] Multiple pairs of spaced partitions, each pair of partitions having its two sides fixedly connected to the inner sides of the two outer plates respectively;

[0009] The two adjacent pairs of partitions and the outer plate together form an independent fireproof chamber, which is filled with a fireproof core layer.

[0010] Each pair of partitions, together with the outer panel, defines a deformation zone, which is configured to bend along a predetermined path so that the fireproof board can be adapted to fit onto the non-planar surface of the structure to be covered.

[0011] Furthermore, the outer plate portion corresponding to the deformation zone is prefabricated with inwardly recessed directional creases, which constitute the predetermined line.

[0012] Furthermore, the outer side of the outer plate of the deformation zone is covered with a bendable corrugated cover plate, and the two sides of the corrugated cover plate are fixedly connected to the outer plate, thereby forming a supplementary filling cavity between the corrugated cover plate and the outer plate, and the supplementary filling cavity is filled with fireproof sealing material.

[0013] Furthermore, the fireproof core layer is one of rock wool board, magnesium oxide board, or calcium silicate board.

[0014] Furthermore, the fireproof core layer is disposed in the middle between the two outer panels, and a sandwich cavity is also provided between the fireproof core layer and the inner sidewall of the outer panel. A sound insulation layer is provided in the sandwich cavity, and the sound insulation layer is a honeycomb aluminum plate or a foam aluminum plate.

[0015] Furthermore, the fire-resistant sealing material is a fire-resistant sealant or a heat-expanding fire-resistant sealant.

[0016] Furthermore, the fireproof core layer and the sound insulation layer, as well as the sound insulation layer and the inner wall of the outer panel, are bonded and fixed together by a high-temperature adhesive.

[0017] This utility model provides a fireproof board. It has the following beneficial effects:

[0018] 1. By pre-setting deformation zones defined by directional creases within the board material, the originally rigid board material gains controllable bending capabilities. Construction workers can easily bend the board to the required angle according to site conditions, tightly fitting the corners or curved surfaces of pipes, beams, columns, and walls. This greatly simplifies the installation process, reduces reliance on skilled construction workers, and effectively minimizes material waste caused by cutting and splicing.

[0019] 2. The independent fireproof chamber and its internal fireproof core layer provide a large area and high efficiency of main body fireproof and heat insulation capabilities; for deformation areas that may become weak points due to bending, an innovative supplementary filling cavity is set up and filled with fireproof sealing material; under the high temperature of a fire, this material can effectively seal or expand to seal potential gaps, ensuring that even in a bent state, the fireproof integrity and continuity of the board are not compromised, ensuring the stability of fireproof performance when irregularly shaped.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 1 to 3 The fireproof board provided by this utility model is designed to combine excellent fireproof performance with outstanding on-site installation adaptability, and is especially suitable for covering building structures with corners or curved surfaces.

[0026] The main structure of the fireproof board consists of two parallel and opposite outer panels 1 forming a framework. Between the outer panels 1, there are multiple pairs of spaced partitions 2. The two sides of each pair of partitions 2 are fixedly connected to the inner sides of the two outer panels 1 by welding, forming a stable internal support frame.

[0027] Please see Figure 1 Two adjacent pairs of partitions 2 and the outer panel 1 together form an independent fireproof chamber 3. The fireproof chamber 3 provides fire resistance to the panel and is filled with a dense fireproof core layer 4. According to a specific embodiment of this utility model, the fireproof core layer 4 can be made of common high-performance fireproof materials such as rock wool board, magnesium oxide board, or calcium silicate board. These materials are fixed in the chamber by a high-temperature adhesive to ensure the stability of the structure.

[0028] In this embodiment, a deformation zone 5 is defined between each pair of partitions 2 and the outer panel 1. The deformation zone 5 is configured to be bent along a predetermined line. A pre-formed inwardly recessed directional crease 6 is pre-fabricated on the portion of the outer panel 1 corresponding to the deformation zone 5, forming the predetermined bending line. This design allows construction workers to easily bend the board along the directional crease 6 during on-site installation, ensuring a perfect fit to non-planar surfaces such as pipe bends and wall corners, solving the problems of difficult installation and excessive seams associated with traditional rigid fireproof boards in such scenarios.

[0029] In addition, a flexible corrugated cover plate 7 is provided on the outer side of the outer panel 1 in the deformation zone 5. This corrugated cover plate 7 is arc-shaped and possesses good longitudinal flexibility. Its two edges are fixedly connected to the surface of the outer panel 1 by mechanical connectors such as rivets or screws. The corrugated cover plate 7 and the outer panel 1 thus enclose a supplementary filling cavity 8. This cavity is filled with fire-retardant sealant or heat-expanding fire-retardant caulking agent, etc. When a fire occurs and the deformation zone is baked by high temperatures, the sealant here can effectively seal any gaps that may exist, or expand to further seal the space, ensuring the continuity and integrity of the fire-resistant performance of the panel.

[0030] In a preferred embodiment of this utility model, see [reference needed]. Figure 1-3 The fireproof core layer 4 is positioned in the middle between the two outer panels 1. A cavity 9 is reserved between the fireproof core layer 4 and the inner wall of the outer panel 1. A sound insulation layer 10 is installed in this cavity 9. The sound insulation layer 10 is preferably made of materials that combine lightweight and high-efficiency sound insulation, such as honeycomb aluminum panels or foam aluminum panels. Honeycomb aluminum panels are preferred because they also have a certain heat insulation capacity, providing additional fire resistance. The fireproof core layer 4, the sound insulation layer 10, and the inner wall of the outer panel 1 are all bonded and fixed with a high-temperature adhesive, thus forming a composite panel that integrates fire resistance, sound insulation, and structural strength.

[0031] During installation, workers apply external force to the deformation zone 5 of the board according to the shape of the structure to be covered. The board then bends smoothly and controllably along the pre-set directional creases 6, achieving a tight fit. In the event of a fire, the fireproof core layer 4 within the large fireproof chamber 3 bears the primary responsibility for fireproofing and heat insulation. In the deformation zone 5, which may become a weak point due to bending, the fireproof sealing material in the supplementary filling cavity 8 on its outer side plays a crucial role in local reinforcement and sealing, thus ensuring that the board provides complete and reliable fire protection in any shape.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
