Description

Technical Field

[0001] This disclosure relates to the field of building sealing technology, and in particular to a flexible fireproof shaped board, a fireproof sealing structure for cable shafts, and a building floor sealing system. Background Technology

[0002] Cable shafts are typically installed between building floors to accommodate cables from each level. If these cable shafts are not properly sealed, flames can easily create a "chimney effect" in the event of a fire, thus increasing the area affected by the fire. Therefore, properly sealing cable shafts is of paramount importance.

[0003] However, since cable shafts are vertical and exposed, a base plate needs to be installed at the bottom of the cable shaft before sealing it, so that the subsequent fireproofing material can effectively seal the cable shaft. However, since the base plate is usually a rigid inorganic or metal plate, when the size of the cable shaft changes, the base plate needs to be mechanically cut. However, the cutting process generates a lot of dust or debris, which can harm the operator's health; and because the metal plate is hard, the edges of the cut base plate will have sharp burrs or corners that can easily scratch the operator. Therefore, the cut base plate needs to be ground. Since there is a gap between the installed base plate and the inner wall of the cable shaft, additional sealant is needed to seal the gap between the base plate and the inner wall of the cable shaft, as well as the gap between the base plate and the through cable harness, resulting in low on-site sealing efficiency. Especially when there are crossbeams in the cable shaft, causing unevenness, the operator has to cut and grind the base plate multiple times to achieve a good fit between the base plate and the inner wall of the cable shaft, resulting in even lower on-site sealing efficiency. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a flexible fireproof shaped board, a fireproof sealing structure for cable shafts, and a building floor sealing system that can be quickly shaped and installed without the need for multiple cutting and grinding operations using power tools, has a good sealing effect, is not easy to fall off, and is especially suitable for sealing applications of uneven structures in cable shafts.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A flexible fireproof shaped board includes a fire-resistant fiber layer, a metal mesh shaped frame, a flexible fireproof putty layer, and a release film. The flexible fireproof putty layer is wrapped around the metal mesh shaped frame, and the metal mesh shaped frame is stacked with the fire-resistant fiber layer and the release film layer respectively through the flexible fireproof putty layer.

[0007] In one embodiment, the metal mesh shaping frame is either a low-carbon steel mesh shaping frame or an aluminum alloy mesh shaping frame.

[0008] In one embodiment, the tensile strength of the low-carbon steel mesh shaping frame is 300MPa-500MPa.

[0009] In one embodiment, the tensile strength of the aluminum alloy mesh shaping frame is 100MPa-300MPa.

[0010] In one embodiment, the thickness of the flexible fireproof putty layer is 2mm-15mm.

[0011] In one embodiment, the mesh openings of the metal mesh shaping frame are diamond-shaped.

[0012] In one embodiment, the thickness of the refractory fiber layer is 0.2 mm to 0.5 mm; and / or,

[0013] The refractory fiber layer includes at least one of aluminum foil fiber layer, polyester fiber layer and glass fiber layer.

[0014] A fireproof sealing structure for cable shafts includes the flexible fireproof shaped plate described in any of the above embodiments.

[0015] In one embodiment, the fireproof sealing structure for cable shafts further includes a fireproof protective layer. The flexible fireproof shaped plate is used to attach to the inner wall of the cable shaft and form a cavity to be sealed. The fireproof protective layer is sealed and filled into the cavity to be sealed.

[0016] A building floor sealing system includes the fireproof sealing structure for cable shafts described in any of the above embodiments.

[0017] Compared with the prior art, this disclosure has at least the following advantages:

[0018] 1) Because the metal mesh shaping frame is stacked with the fire-resistant fiber layer and the release film respectively through the flexible fireproof mortar layer, the flexible fireproof mortar layer can adhere well to the fire-resistant fiber layer and the release film, thus realizing the stacking of the fire-resistant fiber layer, the metal mesh shaping frame, the flexible fireproof mortar layer, and the release film; since the fire-resistant fiber layer, the flexible fireproof mortar layer, and the release film are flexible materials, they are easy to bend and shape; while the metal mesh shaping frame has a suitable degree of flexibility and hardness, so that the metal mesh shaping frame can provide good structural support for the fire-resistant fiber layer and the flexible fireproof mortar layer, making it easy to support the fireproof protection layer; on the other hand, it ensures that the metal mesh shaping frame is easy to bend and shape and does not easily spring back. The operator can shape the flexible fireproof shaping board according to the uneven structure in the cable shaft, so that the flexible fireproof mortar layer of the flexible fireproof shaping board can adhere well to the outer peripheral wall of the uneven structure, thus realizing the flexible fireproof shaping. The flexible fireproof plastic sheet can flexibly change its shape to fit irregular spaces to be sealed, effectively avoiding the problem of lower on-site sealing efficiency caused by the need for multiple cutting and grinding of the base plate in traditional methods. On the other hand, the added metal mesh shaping frame will not cause the flexible fireproof plastic sheet to be too hard, making it impossible for the operator to manually cut the flexible fireproof plastic sheet. This ensures that the operator can manually cut the flexible fireproof plastic sheet according to the sealing structure of the cable shaft, then tear off the release film, and attach the exposed flexible fireproof putty layer to the inner wall of the cable shaft. Then, the operator can shape and fit the flexible fireproof plastic sheet according to the uneven structure of the cable shaft, so that the flexible fireproof plastic sheet can fit the irregular space to be sealed well. In this way, there is no need to use power tools for multiple cutting and grinding operations, which effectively improves the on-site sealing efficiency, especially suitable for sealing applications with uneven structures in cable shafts.

[0019] 2) In conjunction with the use of the fireproof protective layer, since the fireproof protective layer is a foamed fireproof and moisture-proof adhesive before curing, the foamed fireproof and moisture-proof adhesive can effectively fill and seal the gaps in the shearing of the flexible fireproof plastic sheet and the gaps between the flexible fireproof plastic sheet and the inner wall of the cable shaft. This effectively avoids the problem of low on-site sealing efficiency caused by the need for additional sealant when using a base plate as support in the traditional way. In addition, the fireproof protective layer is lightweight, fireproof, and moisture-proof, so that the fireproof protective layer will not cause the flexible fireproof plastic sheet to fall off due to excessive weight. That is, the flexible fireproof plastic sheet can provide good support for the fireproof protective layer and will not fall off during long-term use, and ensure that the fireproof sealing structure of the cable shaft has good fireproof performance.

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.

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.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] Please see Figures 1 to 2 One embodiment of the flexible fireproof shaped board includes a fire-resistant fiber layer 130, a metal mesh shaped frame 140, a flexible fireproof putty layer 150, and a release film 160. The flexible fireproof putty layer 150 is disposed on the metal mesh shaped frame 140, and the metal mesh shaped frame 140 is stacked with the fire-resistant fiber layer 130 and the release film 160 through the flexible fireproof putty layer 150.

[0031] It is understandable that, because the metal mesh shaping frame 140 is layered with the refractory fiber layer 130 and the release film 160 respectively through the flexible fireproof putty layer 150, the flexible fireproof putty layer 150 can better adhere to the refractory fiber layer 130 and the release film 160, thereby realizing the layered arrangement of the refractory fiber layer 130, the metal mesh shaping frame 140, the flexible fireproof putty layer 150 and the release film 160; since the refractory fiber layer 130, the flexible fireproof putty layer 150 and the release film 160 are flexible... The material is easy to bend and shape; the metal mesh shaping frame 140 has a suitable degree of flexibility, which allows it to provide good structural support for the fire-resistant fiber layer 130 and the flexible fireproof mortar layer 150, facilitating the support of the fireproof protection layer 300. On the other hand, it ensures that the metal mesh shaping frame 140 is easy to bend and shape and does not easily spring back. Operators can shape the flexible fireproof shaping board according to the uneven structure within the cable shaft 20, thus ensuring the flexible fireproof mortar layer of the flexible fireproof shaping board... The 150 can adhere well to the outer wall of uneven structures, allowing the flexible fireproof plastic panel to flexibly change its shape to fit irregular spaces to be sealed. This effectively avoids the problem of lower on-site sealing efficiency caused by the need for multiple cutting and grinding of the base plate in traditional methods. On the other hand, the added metal mesh shaping frame 140 prevents the flexible fireproof plastic panel from becoming too rigid, thus ensuring that the operator can cut the flexible fireproof plastic panel according to the sealing structure of the cable shaft 20. Manually cut and then peel off the release film 160, attaching the exposed flexible fireproof mortar layer 150 to the inner wall of the cable shaft 20. Then, the operator can shape and fit the flexible fireproof mortar according to the uneven structure inside the cable shaft 20, so that the flexible fireproof mortar can fit well into the irregular space to be sealed. In this way, there is no need to use power tools for multiple cutting and grinding operations, which effectively improves the on-site sealing efficiency, especially suitable for sealing applications with uneven structures inside the cable shaft 20.

[0032] It is also understandable that, in conjunction with the use of the fireproof protective layer 300, since the fireproof protective layer 300 is a foamed fireproof and moisture-proof adhesive before curing, the foamed fireproof and moisture-proof adhesive can effectively fill and seal the gaps in the shearing of the flexible fireproof plastic sheet and the gaps between the flexible fireproof plastic sheet and the inner wall of the cable shaft 20. This effectively avoids the problem of low on-site sealing efficiency caused by the need for additional sealant when using a base plate as support in the traditional way. In addition, the fireproof protective layer 300 is lightweight, fireproof, and moisture-proof, which allows the flexible fireproof plastic sheet to provide good support for the fireproof protective layer 300 and prevent it from falling off during long-term use. It also ensures that the fireproof sealing structure 10 of the cable shaft has good fireproof performance.

[0033] In one embodiment, the metal mesh shaping frame 140 is either a low-carbon steel mesh shaping frame or an aluminum alloy mesh shaping frame, to ensure that the metal mesh shaping frame 140 has a suitable degree of flexibility and rigidity, thereby ensuring that the operator can manually cut the flexible fireproof shaping board while also ensuring that the flexible fireproof shaping board can provide good support for the fireproof protection layer 300.

[0034] For example, in one embodiment, the tensile strength of the low-carbon steel mesh shaping frame is 300MPa-500MPa, and the elongation after fracture is 25%-35%. As another example, in one embodiment, the tensile strength of the aluminum alloy mesh shaping frame is 100MPa-300MPa, and the elongation after fracture can reach 12%-25%, thereby ensuring that the low-carbon steel mesh shaping frame and the aluminum alloy mesh shaping frame have suitable rigidity. This ensures that the operator can manually cut the flexible fireproof shaping board while also ensuring that the flexible fireproof shaping board provides good support for the fireproof protective layer 300.

[0035] It should be noted that the materials of the low-carbon steel mesh shaping frame, the flexible fireproof mortar layer 150, and the fireproof protection layer 300 are all existing technologies. This disclosure only protects the connection relationship between the low-carbon steel mesh shaping frame, the low-carbon steel mesh shaping frame, the flexible fireproof mortar layer 150, and the fireproof protection layer 300.

[0036] In one embodiment, the thickness of the flexible fireproof putty layer 150 is 2mm-15mm, so as to ensure that the bonding performance can be met by using a thinner flexible fireproof putty layer 150, while also facilitating the formation of a lightweight and thin flexible fireproof shaped board, so as to better adapt to applications in confined spaces.

[0037] In one embodiment, the flexible fireproof putty layer 150 covers the outer surface of the metal mesh molding frame 140. The first side of the flexible fireproof putty layer 150 is used to adhere to the fire-resistant fiber layer 130, and the second side of the flexible fireproof putty layer 150 is used to adhere to the release film 160, thereby achieving the bonding and fixation of the flexible fireproof putty layer 150 with the fire-resistant fiber layer 130 and the release film 160.

[0038] like Figure 2 As shown, in one embodiment, the mesh openings of the metal mesh shaping frame 140 are diamond-shaped holes 142, allowing the operator to bend and shape it, thereby ensuring that the metal mesh shaping frame 140 has a suitable degree of flexibility. Specifically, the metal mesh shaping frame 140 is composed of multiple intersecting metal wires 141 connected together, and the intersecting metal wires 141 are connected to form multiple diamond-shaped holes 142.

[0039] In one embodiment, the thickness of the refractory fiber layer 130 is 0.2 mm to 0.5 mm.

[0040] In one embodiment, the refractory fiber layer 130 includes at least one selected from aluminum foil fiber layer, polyester fiber layer, and glass fiber layer. In a preferred embodiment, the refractory fiber layer 130 is an aluminum foil fiber layer with a thickness of 0.2 mm to 0.5 mm.

[0041] like Figure 3 and Figure 4 As shown, this disclosure also provides a fireproof sealing structure 10 for cable shafts, including the flexible fireproof shaped plate described in any of the above embodiments. In one embodiment, the fireproof sealing structure 10 for cable shafts further includes a fireproof protective layer 300, the flexible fireproof shaped plate being attached to the inner wall of the cable shaft 20 to form a cavity to be sealed, and the fireproof protective layer 300 sealingly filling the cavity to be sealed.

[0042] In use, the operator manually cuts the flexible fireproof molded board according to the sealing structure of the cable shaft 20, then peels off the release film 160, and attaches the exposed flexible fireproof putty layer 150 to the inner wall of the cable shaft 20. This allows the flexible fireproof molded board to act as a support at the bottom of the cable shaft 20, forming a cavity to be sealed. Then, a caulking gun is used to inject foamed fireproof and moisture-proof adhesive into the cavity. After the foamed fireproof and moisture-proof adhesive cures, a fireproof protective layer 300 is formed, effectively sealing the cable shaft 20. When encountering uneven structures within the cable shaft 20, after attaching the flexible fireproof molded board, the operator can shape and fit it according to the uneven structure, ensuring the flexible fireproof molded board fits well into the irregular space to be sealed, thus improving the adaptability of the cable shaft fireproof sealing structure 10.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment, the flexible fireproof plastic panel has a bent overlap 400, thereby improving the connection and fixation between the flexible fireproof plastic panel and the sealing structure of the cable shaft 20.

[0044] In one embodiment, the first, second, and third sidewalls of the flexible fireproof shaped panel are all formed with bent overlaps 400 to better ensure the connection and fixation between the flexible fireproof shaped panel and the sealing structure of the cable shaft 20.

[0045] In one embodiment, the fireproof sealing structure 10 for cable shafts includes a first flexible fireproof shaped plate 100, a second flexible fireproof shaped plate 200, and a fireproof protective layer 300. The edges of the first flexible fireproof shaped plate 100 and the second flexible fireproof shaped plate 200 have semi-open holes. The first flexible fireproof shaped plate 100 is adhered to one inner wall of the sealing structure of the cable shaft 20 in the building wall, and the second flexible fireproof shaped plate 200 is adhered to the other inner wall of the sealing structure of the cable shaft 20 in the building wall, so that the first flexible fireproof shaped plate 100 and the second flexible fireproof shaped plate 200 can form a complete pre-set hole 120 when spliced ​​together. The complete pre-drilled hole 120 can wrap the bundled cable 30; both the first flexible fireproof plastic plate 100 and the second flexible fireproof plastic plate 200 have bent overlap parts 400, which are used for surface bonding of the sealing structure of the cable shaft 20 in the building wall, improving the connection and fixation between the flexible fireproof plastic plate and the sealing structure of the cable shaft 20; so that the first flexible fireproof plastic plate 100 and the second flexible fireproof plastic plate 200 can form a support at the bottom of the sealing structure of the cable shaft 20, and form a cavity to be sealed in the sealing structure of the cable shaft 20, so that the fireproof protective layer 300 can be sealed and filled in the cavity to be sealed.

[0046] This disclosure also provides a building floor sealing system, including the fireproof sealing structure 10 for cable shafts described in any of the above embodiments.

[0047] Compared with the prior art, this disclosure has at least the following advantages:

[0048] 1) Because the metal mesh shaping frame 140 is layered with the refractory fiber layer 130 and the release film 160 respectively through the flexible fireproof mortar layer 150, the flexible fireproof mortar layer 150 can better adhere to the refractory fiber layer 130 and the release film 160, thus realizing the layered arrangement of the refractory fiber layer 130, the metal mesh shaping frame 140, the flexible fireproof mortar layer 150 and the release film 160; since the refractory fiber layer 130, the flexible fireproof mortar layer 150 and the release film 160 are flexible materials, they are easy to bend and shape; while the metal mesh shaping frame 140 has a suitable degree of flexibility and hardness, so that the metal mesh shaping frame 140 can provide good structural support for the refractory fiber layer 130 and the flexible fireproof mortar layer 150, which is convenient for supporting fire protection. The protective layer 300; on the other hand, it ensures that the metal mesh shaping frame 140 is easy to bend and shape and not easy to spring back. On the other hand, it is easy for the operator to cut manually without the need for power tools to grind. The dust-free operation is pollution-free and no other auxiliary cutting tools are required, which effectively improves the efficiency of on-site sealing. On the other hand, the operator can shape the flexible fireproof shaping board according to the uneven structure in the cable shaft 20, so that the flexible fireproof mortar layer 150 of the flexible fireproof shaping board can adhere well to the outer peripheral wall of the uneven structure. That is, the flexible fireproof shaping board can flexibly change its shape to fit the irregular space to be sealed. It effectively avoids the problem of lower on-site sealing efficiency caused by the traditional need to cut and grind the base plate multiple times. In use, the operator manually cuts the flexible fireproof plastic sheet according to the sealing structure of the cable shaft 20, then tears off the release film 160, and attaches the exposed flexible fireproof putty layer 150 to the inner wall of the cable shaft 20. The operator can shape and fit the flexible fireproof plastic sheet according to the uneven structure inside the cable shaft 20 so that the flexible fireproof plastic sheet can fit well into the irregular space to be sealed.

[0049] 2) In conjunction with the use of the fireproof protective layer 300, since the fireproof protective layer 300 is a foamed fireproof and moisture-proof adhesive before curing, the foamed fireproof and moisture-proof adhesive can effectively fill and seal the gaps in the shearing of the flexible fireproof plastic sheet and the gaps between the flexible fireproof plastic sheet and the inner wall of the cable shaft 20. This effectively avoids the problem of low on-site sealing efficiency caused by the need for additional sealant when using a base plate as support in the traditional way. In addition, the fireproof protective layer 300 is lightweight, fireproof, and moisture-proof, so that the fireproof protective layer 300 will not cause the flexible fireproof plastic sheet to fall off due to excessive weight. That is, the flexible fireproof plastic sheet can provide good support for the fireproof protective layer 300 and will not fall off during long-term use, and ensure that the cable shaft fireproof sealing structure 10 has good fireproof performance.
