Description

Technical Field

[0001] This utility model relates to the field of building fire protection technology, and in particular to a quick-installation fire-resistant board for steel structure cladding. Background Technology

[0002] Steel structures are widely used in modern construction projects due to their high strength and light weight. However, steel structures have poor fire resistance. In the event of a fire, the strength of steel will drop rapidly under high temperature, leading to structural collapse and serious loss of life and property. Therefore, steel structures must be protected against fire. Using fire-resistant plates to cover steel structures is a common and effective protection method.

[0003] Existing fire-resistant panels used for steel structure cladding still have shortcomings in practical applications. On the one hand, the internal structure design of some panels is relatively simple, and the multi-layer composite functionality is not strong, resulting in a low fire resistance limit and a lack of sound insulation, thus limiting the protective effect. On the other hand, and more importantly, the installation process is problematic. Traditional fire-resistant panels are often fixed one by one with keels and screws after being butt-jointed on a flat surface when cladding steel structures. This method requires precise on-site measurement and alignment, making the installation process cumbersome, time-consuming, labor-intensive, and inefficient. To improve installation speed, some panels have attempted to use a male-female groove structure for splicing. However, the existing male-female groove design is relatively simple. During installation, especially when vertically stacked, slight deformation due to the tolerance of the panels can cause jamming between the male and female grooves, leading to installation difficulties. Once jammed, disassembly and replacement become very inconvenient, affecting the convenience of construction and subsequent maintenance.

[0004] Therefore, this utility model proposes a quick-installation fire-resistant plate for steel structure cladding to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, such as the male and female groove structures getting stuck during splicing and installation, difficulties in installation and disassembly, cumbersome fixing steps, and the single fire-resistant and sound-insulating structure with poor protective effect, this utility model aims to provide a quick-installation fire-resistant board for steel structure cladding with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a quick-installation fire-resistant plate for steel structure cladding, comprising: a fire-resistant plate shell, a fire-resistant mechanism fixed inside the fire-resistant plate shell, and a quick-installation mechanism.

[0007] The quick installation mechanism includes a mounting protrusion on the top of the fire-resistant board shell and a mounting hole 1 on the top of the fire-resistant board shell, wherein the mounting protrusion is provided with a mating inclined block; the quick installation mechanism also includes a mounting groove on the bottom of the fire-resistant board shell, wherein the mounting groove is provided with an anti-jamming inclined groove; a mounting groove is provided on the lower front side of the fire-resistant board shell, wherein a mounting hole 2 is provided in the mounting groove.

[0008] Furthermore, the mounting protrusion engages with the mounting groove of the other fire-resistant board shell, the mating wedge engages with the anti-jamming wedge of the other fire-resistant board shell, and the mounting hole one engages with the mounting hole two of the other fire-resistant board shell for screw fixing.

[0009] Preferably, the fire-resistant structure includes an inorganic fiberboard, a sound insulation board, a fireproof board one, and a fireproof board two.

[0010] Preferably, the inorganic fiberboard is fixedly installed on the rear side of the inner wall of the fire-resistant board shell.

[0011] Preferably, the sound insulation board is fixedly connected to the front side of the inorganic fiberboard.

[0012] Preferably, the fireproof board is fixedly connected to the front side of the soundproof board.

[0013] Preferably, the second fireproof board is fixedly connected to the front side of the inner wall of the fire-resistant board shell.

[0014] Preferably, the mating wedge has an inclination angle.

[0015] Preferably, the anti-jamming groove has an inclination angle.

[0016] Preferably, the tilt angle of the anti-jamming groove is adapted to the tilt angle of the mating inclined block.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of jamming, inconvenient alignment, difficult installation and disassembly, and cumbersome fixing steps in the prior art when splicing and installing fire-resistant boards by setting installation protrusions and matching inclined blocks on the top of the fire-resistant board shell, and setting installation grooves and anti-jamming inclined grooves on the bottom of the fire-resistant board shell, and setting installation hole one and installation hole two. It achieves automatic guidance and alignment during installation, prevents jamming, makes installation convenient and fast, disassembly convenient, and ensures a stable connection.

[0019] 2. This utility model solves the problems of the existing fire-resistant board material having a single structure, insufficient fire resistance and heat insulation performance, and lack of sound insulation function by setting a multi-layer fire-resistant structure composed of inorganic fiber board, sound insulation board, fireproof board one and fireproof board two inside the fire-resistant board shell. It achieves the synergistic effect of multiple barriers, high fire resistance limit, good heat insulation and sound insulation effect, and can effectively protect the internal encapsulated structure.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4As shown, a quick-installation fire-resistant sheet for steel structure cladding includes a fire-resistant sheet shell 1, a quick-installation mechanism 3 disposed on the fire-resistant sheet shell 1, and a fire-resistant mechanism 4 fixed inside the fire-resistant sheet shell 1. The fire-resistant sheet shell 1 serves as the load-bearing frame for the entire sheet, the quick-installation mechanism 3 enables rapid splicing and fixing between sheets, and the fire-resistant mechanism 4 provides fire resistance and sound insulation functions. The fire-resistant mechanism 4 includes an inorganic fiber board 41, a sound insulation board 42, a first fireproof board 43, and a second fireproof board 44. The inorganic fiber board 41 is fixedly installed on the rear side of the inner wall of the fire-resistant sheet shell 1, and the sound insulation board 42 is fixedly connected to... On the front side of the inorganic fiber board 41, fireproof board 1 43 is fixedly connected to the front side of the sound insulation board 42, and fireproof board 2 44 is fixedly connected to the front side of the inner wall of the fireproof board shell 1. The quick installation mechanism 3 includes an installation protrusion 31 opened on the top of the fireproof board shell 1 and an installation hole 1 35 set on the top of the fireproof board shell 1. The installation protrusion 31 is provided with a matching inclined block 34. The quick installation mechanism 3 also includes an installation groove 32 opened on the bottom of the fireproof board shell 1. An anti-jamming inclined groove 33 is provided in the installation groove 32. An installation groove 2 is opened on the lower front side of the fireproof board shell 1. An installation hole 2 36 is opened in the installation groove 2.

[0029] Please refer to Figure 1 , Figure 2 and Figure 4 The mounting protrusion 31, the mating wedge 34, and the mounting hole 35 of the quick-installation mechanism 3 are all located on the top of the fire-resistant board shell 1, while the mounting groove 2, the mounting recess 32, the anti-jamming groove 33, and the mounting hole 36 are all located on the bottom of the fire-resistant board shell 1. This layout allows the top of one fire-resistant board shell 1 to mate with the bottom of another fire-resistant board shell 1. Specifically, the mounting protrusion 31 is formed as a solid structure extending upward from the top of the fire-resistant board shell 1. The mating wedge 34 is integrally formed at a specific position on the mounting protrusion 31 and has an inclined angle. The mounting hole 35 penetrates the top platform of the fire-resistant board shell 1. At the same time, the mounting recess 32 is formed as a groove structure recessed upward from the bottom of the fire-resistant board shell 1. The anti-jamming groove 33 is integrally formed in the mounting recess 32. The inner wall has an anti-jamming groove 33 with an inclination angle that matches the mating inclined block 34. The mounting groove 2 is located on the lower front end of the fire-resistant plate shell 1, and the mounting hole 36 is located on the bottom surface of the mounting groove 2. In the assembled state, the mounting protrusion 31 of the upper fire-resistant plate shell 1 engages and inserts into the mounting groove 32 of the lower fire-resistant plate shell 1. The mating inclined block 34 and the inclined surface of the anti-jamming groove 33 contact each other and guide each other. This convex-concave engagement structure with double inclined surface guidance ensures that the two plates can be automatically guided to the correct position when they are joined and prevents jamming during disassembly. When the engagement is in place, the mounting hole 35 of the upper fire-resistant plate shell 1 and the mounting hole 36 of the lower fire-resistant plate shell 1 are automatically aligned, allowing fasteners such as screws to pass through the two holes, thereby achieving quick locking and fixing of the two plates.

[0030] As a preferred embodiment, to provide efficient and multifunctional protection, please refer to... Figure 1 and Figure 4 The internal structure of the fire-resistant mechanism 4 is preferably configured as a multi-layer composite structure. The fire-resistant mechanism 4 includes an inorganic fiberboard 41, a sound insulation board 42, a first fireproof board 43, and a second fireproof board 44. These four layers of boards are tightly bonded inside the fire-resistant shell 1 and fixed by adhesives or snap-fit ​​structures. Specifically, the inorganic fiberboard 41 is preferably a Class A fire-resistant material such as calcium silicate board or glass magnesium board. The inorganic fiberboard 41 is fixedly installed on the rear side of the inner wall of the fire-resistant shell 1, serving as the first line of defense closest to the protected structure. The sound insulation board 42 is preferably... Rock wool board or foam ceramic board, sound insulation board 42 is fixedly connected to the front side of inorganic fiber board 41 to provide good sound insulation and noise reduction effect while being fire resistant. Fireproof board 43 can be made of the same or different fireproof material as inorganic fiber board 41. Fireproof board 43 is fixedly connected to the front side of sound insulation board 42. Fireproof board 44 is fixedly connected to the front side of the inner wall of fireproof board shell 1, that is, the side closest to the mounting groove 2. Fireproof board 43 and fireproof board 44 together form a double fireproof barrier, which greatly improves the fire resistance limit of the board.

[0031] As another preferred embodiment, to ensure efficient guiding and anti-jamming performance of the mounting protrusion 31 and the mounting groove 32 during docking, please refer to... Figure 4 The mating wedge 34 is configured as a sloped structure with a predetermined tilt angle. The mating wedge 34 is preferably an integrally formed wedge block along the insertion direction of the mounting protrusion 31. The anti-jamming groove 33 is configured as a groove structure with a predetermined tilt angle. The anti-jamming groove 33 is preferably a V-shaped or U-shaped groove formed on the inner wall of the mounting groove 32. More preferably, the tilt angle of the anti-jamming groove 33 is equal in value and parallel to the tilt angle of the mating wedge 34 in direction. This fitting arrangement ensures that when the mounting protrusion 31 is inserted into the mounting groove 32, the mating wedge 34 can slide precisely into the anti-jamming groove 33. The guiding effect of the two slopes automatically corrects small deviations and prevents the two from jamming due to excessive friction or deformation when disassembly is required, thus ensuring the reliability of quick installation and quick disassembly.

[0032] Working principle:

[0033] When installing steel structure columns or walls, the operator first takes the first fire-resistant board shell 1 and flatly attaches the rear side of the inner wall of the fire-resistant board shell 1, that is, the rear side of the mounting surface where the inorganic fiber board 41 is located, to the surface of the steel structure or wall to be protected. The operator can use the mounting groove 2 opened on the lower front side of the fire-resistant board shell 1, and the mounting hole 36 opened inside the mounting groove 2 to use screws or expansion bolts to fasten the first fire-resistant board shell 1 firmly and initially fix it to the steel structure or wall, thus completing the reference positioning of the first board.

[0034] Next, when installing the second sheet, for example, when stacking vertically upwards, the operator takes the second fire-resistant sheet shell 1 and aligns the bottom of the second fire-resistant sheet shell 1 with the top of the first fire-resistant sheet shell 1 for insertion. During the insertion process, the mounting groove 32 on the bottom of the second fire-resistant sheet shell 1 and the mounting protrusion 31 on the top of the first fire-resistant sheet shell 1 begin to engage with each other. As the mounting protrusion 31 is inserted into the mounting groove 32, the anti-jamming groove 33 on the second fire-resistant sheet shell 1, which is located inside the mounting groove 32, will inevitably come into contact and slide with the mating oblique block 34 on the mounting protrusion 31 of the first fire-resistant sheet shell 1. Because the mating oblique block 34 has a wedge-shaped inclined surface structure with a specific inclination angle, and the anti-jamming groove 33 is also correspondingly designed with... The guide groove structure has an inclined angle that matches the mating wedge 34. Therefore, when the two inclined structures interact, they generate a guiding force that automatically centers and corrects deviations. This guiding force guides the mounting protrusion 31 to overcome possible installation tolerances or slight positional offsets and smoothly and accurately slide into the deepest part of the mounting groove 32. This double inclined guide mating design of mating wedge 34 and anti-jamming inclined groove 33 not only ensures that multiple plates can be quickly and accurately aligned when stacked, avoiding the installation difficulties or jamming caused by misalignment in traditional male and female groove structures, but also allows the mounting protrusion 31 to be easily pulled out of the mounting groove 32 by using the reverse inclined guiding action when maintenance or disassembly is required in the future, realizing the dual functions of quick installation and quick disassembly.

[0035] Once the mounting protrusion 31 of the second fire-resistant board shell 1 is fully engaged, the two boards have achieved initial mechanical locking through the convex-concave structure. To achieve a more secure fixation, the mounting hole 36 inside the bottom mounting groove 2 on the second fire-resistant board shell 1 is precisely aligned with the mounting hole 35 on the top of the first fire-resistant board shell 1 in terms of spatial position, forming a through-type fixing channel. At this point, the operator can conveniently use screws to fasten the second fire-resistant board shell 1 through the mounting hole 36 and screw it into the mounting hole 35 of the first fire-resistant board shell 1, thereby firmly locking the second fire-resistant board shell 1 and the first fire-resistant board shell 1 together to form a stable whole. The operator only needs to repeat the above engagement and locking steps to efficiently and neatly complete the large-area laying or covering operation of multiple fire-resistant boards.

[0036] During use after installation or in high-temperature environments such as fires, the fire-resistant mechanism 4, fixed inside the fire-resistant outer shell 1, provides protection. The carefully designed multi-layered composite structure of the fire-resistant mechanism 4 collaboratively provides a three-dimensional protective barrier. High-temperature heat from a fire or external environment first contacts the outermost layer, the fireproof plate 44 fixed to the front of the inner wall of the fire-resistant outer shell 1. The fireproof plate 44, utilizing its material properties, quickly blocks the intrusion of the first wave of heat. Residual heat that is not completely blocked continues to transfer inward to the fireproof plate 43 fixed to the front of the sound insulation plate 42. The fireproof plate 43, acting as the second fire barrier, provides a second effective heat blockage. This double fire barrier design, formed by the fireproof plates 43 and 44, can greatly dissipate heat energy and effectively protect the fire-resistant structure. The internal structure of the fire-resistant outer shell 1 is stable. Meanwhile, the sound insulation board 42, which is fixedly connected to the front of the inorganic fiber board 41, not only absorbs sound waves and provides a quiet sound insulation effect under normal conditions, but also has excellent Class A fire resistance and heat insulation performance in a fire. Therefore, the sound insulation board 42 also plays an auxiliary role in heat insulation, further slowing down the speed of heat transfer inward. Finally, the inorganic fiber board 41, which is fixedly installed on the rear side of the inner wall of the fire-resistant outer shell 1 as the last key line of defense, utilizes its excellent chemical stability, high temperature resistance and low thermal conductivity to tightly adhere to the protected wall or steel structure. This ensures that even if there is still residual heat after the high temperature penetrates multiple layers of barriers, it will not cause melting, deformation or strength reduction of the protected structure. Thus, a comprehensive effect of efficient and reliable fire resistance and sound insulation is achieved.
