Abstract
Description
Technical Field
[0001] This disclosure relates to the field of fireproof sealing technology, and in particular to a self-locking, ceramic-compatible fireproof sealing structure and fireproof sealing device. Background Technology
[0002] Fire-resistant, porcelain-like structures can be used for fire-resistant sealing of through-holes in building firewalls. For example, the fire-resistant, porcelain-like module disclosed in Chinese Patent Document CN 116218234 A is made by directly molding and vulcanizing a fire-resistant, porcelain-like material, which is then fitted into a metal frame. The metal frame is then fitted into the hole in the firewall. For details, please refer to that document. Figure 2 This is to achieve fireproof sealing of the holes.
[0003] However, in practical applications, the high rigidity of the metal frame and firewall makes disassembly and assembly difficult for operators, resulting in wear or deformation of the ceramic fireproof sealing module due to the large force required during disassembly and assembly. Utility Model Content
[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a self-locking ceramic fireproof sealing structure and fireproof sealing device that reduces the problem of wear or deformation of ceramic fireproof sealing modules during disassembly and assembly, and improves the adaptability to sealing different spatial holes.
[0005] The purpose of this disclosure is achieved through the following technical solution:
[0006] A self-locking, ceramic-compatible fireproof sealing structure includes at least one ceramic-compatible elastic fireproof module.
[0007] Each of the ceramizable elastic fireproof modules includes a ceramizable elastic fireproof pillow and a self-locking Velcro strap; the self-locking Velcro strap is arranged around the outer peripheral wall of the ceramizable elastic fireproof pillow; each of the ceramizable elastic fireproof modules is stacked and sealed in the hole in sequence, and each adjacent ceramizable elastic fireproof module is fixed by the self-locking Velcro strap.
[0008] In one embodiment, the self-locking Velcro is bonded to the outer peripheral wall of the ceramicizable elastic fireproof pillow via an adhesive layer.
[0009] In one embodiment, the self-locking hook and loop fastener includes a base layer, an adhesive layer, and a self-adhesive layer. The base layer is connected end to end to form an installation cavity for accommodating the ceramicizable elastic fireproof pillow. The adhesive layer is disposed on the side of the base layer facing the installation cavity. The adhesive layer is bonded to the inner wall of the installation cavity. The self-adhesive layer is disposed on the side of the base layer facing away from the installation cavity.
[0010] In one embodiment, the outer peripheral wall of the ceramicizable elastic fireproof pillow is recessed to form an annular mounting groove, and the self-locking Velcro is sleeved in the annular mounting groove and at least partially protrudes from the annular mounting groove.
[0011] In one embodiment, the self-locking hook and loop fastener is a hook and loop fastener with both hook and loop fasteners; and / or,
[0012] The self-locking hook and loop fastener is a one-piece molded structure.
[0013] In one embodiment, the number of self-locking Velcro straps is at least two.
[0014] In one embodiment, each of the self-locking Velcro straps is spaced apart along the length of the ceramicizable elastic fireproof pillow.
[0015] In one embodiment, the ceramizable elastic fireproof pillow includes a ceramizable silicone rubber layer and an elastic fireproof and heat-insulating block, wherein the ceramizable silicone rubber layer is disposed on the outer surface of the elastic fireproof and heat-insulating block.
[0016] In one embodiment, the ceramicizable elastic fireproof pillow further includes a flame-retardant label layer, which is disposed on the outer peripheral wall of the ceramicizable silicone rubber layer.
[0017] A fireproof sealing device includes the self-locking, ceramic-compatible fireproof sealing structure described in any of the above embodiments.
[0018] Compared with the prior art, this disclosure has at least the following advantages:
[0019] 1) Each of the described ceramic-like elastic fireproof modules includes a ceramic-like elastic fireproof pillow and self-locking hook and loop fasteners; the self-locking hook and loop fasteners are arranged around the outer peripheral wall of the ceramic-like elastic fireproof pillow; when multiple ceramic-like elastic fireproof modules are stacked and sealed in the hole in sequence, each adjacent ceramic-like elastic fireproof module can be fixed by the self-locking hook and loop fasteners, that is, each adjacent ceramic-like elastic fireproof module can be fixed by its own self-locking hook and loop fasteners, thereby realizing the self-assembly and self-locking effect of multiple ceramic-like elastic fireproof modules, and thus realizing the self-locking type of ceramic-like fireproof sealing structure. Because the self-locking hook and loop fasteners have a certain degree of flexibility, the rigidity of the self-locking hook and loop fasteners is lower than that of the metal frame, ensuring that the operator can disassemble and assemble with less effort, thereby reducing the problem of wear or deformation of the ceramic-like fireproof sealing modules during disassembly and assembly.
[0020] 2) Because the self-locking Velcro is surrounded by the outer wall of the ceramic elastic fireproof pillow, it ensures that the ceramic elastic fireproof module is equipped with self-locking Velcro at all 360 degrees. This allows the ceramic elastic fireproof modules at different stacking angles to be effectively bonded and fixed. Furthermore, because the ceramic elastic fireproof pillow has a certain degree of elasticity, it is easy for the operator to squeeze and deform it, thereby sealing and plugging different spatial holes. This better adapts to the sealing requirements of different spatial holes, thus improving the adaptability of sealing different spatial holes. Attached Figure Description

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0032] Please see Figure 4 , Figure 2 and Figure 3 One embodiment of the self-locking ceramizable fireproof sealing structure 10 includes at least one ceramizable elastic fireproof module 100. Each ceramizable elastic fireproof module 100 includes a ceramizable elastic fireproof pillow 110 and a self-locking Velcro 120. The self-locking Velcro 120 is arranged around the outer peripheral wall of the ceramizable elastic fireproof pillow 110. Each ceramizable elastic fireproof module 100 is stacked and sealed in the hole 31 in sequence, and each adjacent ceramizable elastic fireproof module 100 is glued and fixed by the self-locking Velcro 120.
[0033] It is understood that each of the ceramizable elastic fireproof modules 100 includes a ceramizable elastic fireproof pillow 110 and a self-locking Velcro 120; the self-locking Velcro 120 is arranged around the outer peripheral wall of the ceramizable elastic fireproof pillow 110; when multiple ceramizable elastic fireproof modules 100 are stacked and sealed in the hole 31 in sequence, each adjacent ceramizable elastic fireproof module 100 can be glued and fixed by the self-locking Velcro 120, that is, each adjacent ceramizable elastic fireproof module 100 can be glued and fixed by its own self-locking Velcro 120, thereby realizing the self-assembly and self-locking effect of multiple ceramizable elastic fireproof modules 100, and thus realizing the self-locking of the ceramizable fireproof sealing structure. Because the self-locking Velcro 120 has a certain degree of flexibility, the rigidity of the self-locking Velcro 120 is lower than that of the metal frame, ensuring that the operator has less effort in disassembly and assembly, thereby reducing the problem of wear or deformation of the ceramizable fireproof sealing module during disassembly and assembly.
[0034] It is understandable that, because the self-locking Velcro 120 is arranged around the outer peripheral wall of the ceramicizable elastic fireproof pillow 110, it ensures that the ceramicizable elastic fireproof module 100 is equipped with self-locking Velcro 120 at all 360 degrees. This allows the ceramicizable elastic fireproof modules 100 at different stacking angles to be effectively bonded and fixed. Furthermore, because the ceramicizable elastic fireproof pillow 110 has a certain degree of elasticity, it is easy for the operator to squeeze and deform it, thereby sealing different spatial holes 31 and better adapting to the sealing requirements of different spatial holes 31, thus improving the adaptability to sealing different spatial holes 31. It is worth mentioning that, because the ceramicizable elastic fireproof module 100 has elastic properties, the operator can stack and squeeze it according to the actual hole 31 situation, thereby effectively sealing the hole 31.
[0035] like Figure 3 As shown, in one embodiment, the self-locking hook and loop fastener 120 is bonded to the outer peripheral wall of the ceramicizable elastic fireproof pillow 110 through the adhesive layer 122, so as to achieve the bonding and fixation of the self-locking hook and loop fastener 120 to the outer peripheral wall of the ceramicizable elastic fireproof pillow 110.
[0036] In one embodiment, the self-locking hook and loop fastener 120 includes a base layer 121, an adhesive layer 122, and a self-adhesive layer 123. The base layer 121 is connected end to end to form an installation cavity, which is used to accommodate the ceramic elastic fireproof pillow 110. The adhesive layer 122 is disposed on the side of the base layer 121 facing the installation cavity. The adhesive layer 122 is bonded to the inner wall of the installation cavity. The self-adhesive layer 123 is disposed on the side of the base layer 121 facing away from the installation cavity, so that the ceramic elastic fireproof pillow 110 located in the installation cavity can be bonded and fixed to the base layer 121 by the adhesive layer 122, thereby realizing the bonding and fixation of the self-locking hook and loop fastener 120 to the outer peripheral wall of the ceramic elastic fireproof pillow 110.
[0037] In one embodiment, the self-locking hook and loop fastener 120 is a one-piece molded structure to ensure that the self-locking hook and loop fastener 120 has high connection strength, thereby improving the service life of the self-locking hook and loop fastener 120.
[0038] In one embodiment, the adhesive layer 122 is a known material, and those skilled in the art can choose existing polyurethane flame retardant adhesive to achieve a firm bond between the self-locking Velcro 120 and the ceramicizable elastic fireproof pillow 110.
[0039] It is understandable that if the self-locking hook and loop fastener 120 protrudes from one side of the ceramicizable elastic fireproof pillow 110, the increased self-locking hook and loop fastener 120 would reduce the tightness of the stacking of adjacent ceramicizable elastic fireproof pillows 110, thus affecting the sealing effect of the self-locking ceramicizable fireproof sealing structure 10. Therefore, in one embodiment, the outer peripheral wall of the ceramicizable elastic fireproof pillow 110 is recessed to form an annular mounting groove. The self-locking hook and loop fastener 120 is fitted into the annular mounting groove and at least partially protrudes from the annular mounting groove. In this way, the added annular mounting groove can limit and fix the self-locking hook and loop fastener 120, effectively preventing the self-locking hook and loop fastener 120 from easily falling off due to large external forces. It also reduces the protruding thickness of the self-locking hook and loop fastener 120, effectively improving the tightness of the stacking of adjacent ceramicizable elastic fireproof pillows 110, thereby improving the sealing effect of the self-locking ceramicizable fireproof sealing structure 10.
[0040] In one embodiment, the thickness of the self-locking hook and loop fastener 120 is 1mm to 5mm to ensure that the thickness of the protrusion of the self-locking hook and loop fastener 120 is appropriate. Under the premise of ensuring that the self-locking hook and loop fastener 120 and the ceramic elastic fireproof pillow 110 have a high connection strength, it also ensures the tightness of the stacking of adjacent ceramic elastic fireproof pillows 110, thereby improving the sealing effect of the self-locking ceramic fireproof sealing structure 10.
[0041] In one embodiment, the self-locking hook and loop fastener 120 is a hook and loop fastener with both hook and loop sides, ensuring that either side of the two self-locking hook and loop fasteners 120 can be glued and fixed without distinguishing between the hook side and the loop side, so that the operator can quickly complete the assembly. Furthermore, since the self-locking hook and loop fastener 120 is a hook and loop fastener with both hook and loop sides, it also saves space, effectively reducing the inconvenience of storing the hook side or loop side of traditional hook and loop fasteners.
[0042] like Figure 1 As shown, in one embodiment, the number of self-locking hook and loop fasteners 120 is at least two, so that the added self-locking hook and loop fasteners 120 can increase the bonding strength of each adjacent ceramic elastic fireproof module 100, thereby improving the stability of the connection of the self-locking ceramic fireproof sealing structure 10.
[0043] Specifically, in one embodiment, each of the self-locking hook and loop fasteners 120 is spaced apart along the length direction of the ceramic elastic fireproof pillow 110 to ensure that the self-locking hook and loop fasteners 120 are well distributed along the length direction of the ceramic elastic fireproof pillow 110, thereby ensuring the bonding strength of each adjacent ceramic elastic fireproof module 100.
[0044] In one embodiment, there are two self-locking hook and loop fasteners 120, which are respectively distributed at both ends of the ceramicizable elastic fireproof pillow 110.
[0045] In one embodiment, the ceramizable elastic fireproof pillow 110 includes a ceramizable silicone rubber layer 111 and an elastic fireproof and heat-insulating block 112. The ceramizable silicone rubber layer 111 is coated on the outer surface of the elastic fireproof and heat-insulating block 112, so that the silicone rubber layer 111 will undergo a ceramic transformation under high temperature flame (300℃~1500℃) to rapidly sinter into a hard ceramic layer. This effectively improves the fire resistance and resistance to fire erosion of the ceramizable silicone rubber layer 111, thereby ensuring the stability and durability of the ceramizable elastic fireproof pillow 110 in high temperature environments. This ensures that the ceramizable elastic fireproof pillow 110 can withstand extremely high temperatures and pressures in a fire and is not easily broken or deformed.
[0046] Furthermore, the combustion products of the ceramicizable silicone rubber layer 111 under high-temperature flames (300℃~1500℃) are only O2, H2O, and SiO2, with a smoke density ≤15 (GB / T 17651) and smoke toxicity reaching ZA1 level (the highest safety level for polymer materials), thus achieving low smoke and non-toxicity. The ceramicizable silicone rubber layer 111 exhibits good flexibility under normal conditions (tensile strength ≥5MPa, elongation at break ≥300%), allowing for bending processing. After ceramicization, the flexural strength increases by 30%~50%, and the resistance to compression puncture is significantly enhanced, achieving flame retardancy and self-extinguishing without the need for halogenated flame retardants, thereby improving the fire resistance of the ceramicizable silicone rubber layer 111.
[0047] In one embodiment, the ceramicizable silicone rubber layer 111 is a ceramicizable silicone rubber outer sheath bag, which includes a fiber cloth and a silicone layer. The ceramicizable silicone rubber outer sheath bag is used to house the elastic fireproof and heat-insulating block 112.
[0048] It should be noted that since the ceramicized silicone rubber outer bag and the elastic fireproof and heat-insulating block 112 are known materials, the ceramicized silicone rubber outer bag can be sewn from the ceramicized silicone rubber outer bag described in Chinese Patent Document No. CN 219789515 U; the elastic fireproof and heat-insulating block 112 can be a polyurethane fireproof and heat-insulating block. Therefore, they are not specifically described in this disclosure. This disclosure only protects the connection method between the ceramicized silicone rubber outer bag, the elastic fireproof and heat-insulating block 112, and the self-locking Velcro 120.
[0049] like Figure 3 As shown, in one embodiment, the ceramizable elastic fireproof pillow 110 further includes a flame-retardant label layer 113, which is disposed on the outer peripheral wall of the ceramizable silicone rubber layer 111. Since the release force of the ceramizable silicone rubber layer 111 is relatively small, the added flame-retardant label layer 113 effectively improves the peel strength of the ceramizable silicone rubber layer 111 to meet the adhesive strength requirements, and enhances the connection strength between the self-locking Velcro 120 and the flame-retardant label layer 113, thus helping to form a strong adhesive structure.
[0050] In one embodiment, the ceramicizable resilient fireproof module 100 further includes a printed identification layer disposed on the outer surface of the flame-retardant label layer 113 to enable identification of each ceramicizable resilient fireproof module 100.
[0051] In one embodiment, an annular mounting groove is recessed within the flame-retardant label layer 113.
[0052] like Figure 4 and Figure 5 As shown, this disclosure also provides a fireproof sealing device 1, including the self-locking, ceramic-type fireproof sealing structure 10 described in any of the above embodiments. The fireproof sealing device 1 further includes a cable tray 20 and a building firewall. The building firewall has a hole 31, and the cable tray 20 is disposed through the hole 31. Multiple ceramic-type elastic fireproof modules 100 of the self-locking, ceramic-type fireproof sealing structure 10 are stacked and compressed to seal the outer peripheral wall of the cable tray 20 to achieve sealing and fixing of the cable tray 20. The cable tray 20 has multiple cables to achieve connection between adjacent cables.
[0053] Compared with the prior art, this disclosure has at least the following advantages:
[0054] 1) Each of the ceramizable elastic fireproof modules 100 includes a ceramizable elastic fireproof pillow 110 and a self-locking Velcro 120; the self-locking Velcro 120 is arranged around the outer peripheral wall of the ceramizable elastic fireproof pillow 110; when multiple ceramizable elastic fireproof modules 100 are stacked and sealed in the hole 31 in sequence, each adjacent ceramizable elastic fireproof module 100 can be glued and fixed by the self-locking Velcro 120, that is, each adjacent ceramizable elastic fireproof module 100 can be glued and fixed by its own self-locking Velcro 120, thereby realizing the self-assembly and self-locking effect of multiple ceramizable elastic fireproof modules 100, and thus realizing the self-locking type of the ceramizable fireproof sealing structure. Since the self-locking Velcro 120 has a certain degree of flexibility, the rigidity of the self-locking Velcro 120 is lower than that of the metal frame, ensuring that the operator can disassemble and assemble with less effort, thereby reducing the problem of wear or deformation of the ceramizable fireproof sealing module during disassembly and assembly.
[0055] 2) Since the self-locking Velcro 120 is arranged around the outer peripheral wall of the ceramic elastic fireproof pillow 110, it ensures that the ceramic elastic fireproof module 100 is provided with self-locking Velcro 120 at all 360 degrees. This allows the ceramic elastic fireproof modules 100 at different stacking angles to be effectively bonded and fixed. Furthermore, since the ceramic elastic fireproof pillow 110 has a certain degree of elasticity, it is easy for the operator to squeeze and deform it, thereby sealing and plugging different spatial holes 31. This better adapts to the sealing requirements of different spatial holes 31, thus improving the adaptability of sealing different spatial holes 31.
[0056] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
