[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0030] like Figure 1 and Figure 2 As shown, the fireproof sealing plate 100 of the present embodiment has a perforation 1001. The fireproof sealing plate 100 includes a first metal plate 1, a second metal plate 2, and a phase change energy storage layer 3. The first metal plate 1 and the second metal plate 2 are stacked, and the phase change energy storage layer 3 is disposed between the first metal plate 1 and the second metal plate 2. The first metal plate 1 and the second metal plate 2 can be metal plates, and the phase change energy storage layer 3 is made of a phase change energy storage material.
[0031] The operating principle of the phase-change energy storage layer 3 is as follows: the phase-change material in the phase-change energy storage layer 3 undergoes a phase change due to temperature fluctuations. When the temperature rises above the phase-change temperature of the phase-change energy storage material, the phase-change energy storage material changes from solid to liquid, absorbing a large amount of heat during the phase-change process. The temperature of the phase-change energy storage material remains constant during the phase-change process, and most of the heat is absorbed by the phase-change energy storage layer 3. The phase-change temperature of the phase-change energy storage material can be selected as needed; for example, a phase-change temperature of 120°C to 150°C can be selected.
[0032] When the fireproof sealing plate 100 of the embodiment of the present invention is in use, the fireproof sealing plate 100 is installed in the installation hole of the building structure, the pipe is passed through the perforation 1001, and the cable is passed through the pipe, so that the cable passes through the building structure, and the installation hole of the building structure is blocked by the fireproof sealing plate 100. When a fire occurs at the fireproof sealing plate 100, the phase change energy storage layer 3 absorbs heat through phase change, reducing the temperature increase rate of the first metal plate 1 and the second metal plate 2, so that the first metal plate 1 and the second metal plate 2 are always at a lower temperature, thereby preventing the first metal plate 1 and the second metal plate 2 from deforming, avoiding the formation of large cracks between the fireproof sealing plate 100 and the building structure, thereby preventing smoke or open flames from entering the building through the gap, and ensuring the safety of people and property in the building. In this way, the reliability of the fireproof sealing plate 100 is improved.
[0033] Optionally, the first metal plate 1 and the second metal plate 2 are explosion-proof plates. In other words, the first metal plate 1 and the second metal plate 2 are metal plates with explosion-proof function.
[0034] In some embodiments, as Figure 2 As shown, the fireproof sealing plate 100 further includes a heat insulation layer 4, which is arranged between the phase change energy storage layer 3 and the first metal plate 1. The heat insulation layer 4 can be heat insulation cotton, heat insulation board, etc.
[0035] The thermal insulation layer 4 plays a role in reducing heat transfer, that is, reducing the heat transfer between the phase change energy storage layer 3 and the first metal plate 1, thereby reducing the heat transfer between the phase change energy storage layer 3 and the first metal plate 1, reducing the deformation of the first metal plate 1 caused by temperature changes, and further improving the reliability of the fireproof sealing plate 100.
[0036] The temperature of the phase change energy storage material remains constant during the phase change process, and most of the heat is absorbed by the phase change energy storage layer 3, so that the phase change energy storage layer 3 acts as a constant temperature bridge between the insulation layer 4 and the second metal plate 2, reducing the deformation of the first metal plate 21 caused by temperature changes.
[0037] Alternatively, as Figure 1 and Figure 2 As shown, the fireproof sealing plate 100 includes a frame 5, which is arranged between the first metal plate 1 and the second metal plate 2 and connected to the first metal plate 1 and the second metal plate 2. The frame 5 has a receiving cavity 51, and the phase change energy storage layer 3 includes a phase change energy storage module 31, which is filled in the receiving cavity 51. The heat insulation layer 4 is arranged between the frame 5 and the first metal plate 1.
[0038] The frame 5 may be a metal frame, for example, a stainless steel frame. The phase change energy storage module and the heat preservation module may be bonded to the frame 5.
[0039] By providing the frame 5 and filling the phase change energy storage module 31 in the accommodating cavity 51 of the frame 5, the frame 5 supports the phase change energy storage module 31, facilitating the installation and fixation of the phase change energy storage layer 3. Thus, the assembly efficiency of the fireproof sealing plate 100 can be improved.
[0040] Alternatively, as Figure 2 As shown, there are multiple accommodating cavities 51 and multiple phase-change energy storage modules 31 , and each accommodating cavity 51 is filled with a phase-change energy storage module 31 .
[0041] By providing a plurality of accommodating cavities 51 , the support reliability of the frame 5 for the phase change energy storage module can be increased, and the structural strength of the fireproof sealing plate 100 can be improved.
[0042] Of course, in other embodiments, only one accommodating cavity 51 may be provided.
[0043] Alternatively, as Figure 2As shown, the plurality of accommodating cavities 51 are arranged in a rectangular array.
[0044] By arranging the plurality of accommodating cavities 51 in a rectangular array, the manufacturing of the frame 5 is facilitated, thereby facilitating the manufacturing of the fireproof blocking plate 100, and the cost of the fireproof blocking plate 100 is reduced.
[0045] Optionally, the frame 5, the first metal plate 1 and the second metal plate 2 are provided with connecting holes through which fasteners pass. The fasteners can be bolts, screws, etc.
[0046] By providing the frame 5, the first metal plate 1 and the second metal plate 2 with connecting holes, the fasteners can pass through the frame 5, the first metal plate 1 and the second metal plate 2 in sequence, and connect with the building structure, thereby improving the connection reliability of the fireproof blocking plate 100 and the building structure.
[0047] As shown, Figure 3 The fireproof blocking assembly 1000 of the embodiment of the present disclosure includes the fireproof blocking plate 100 and a pipe, the fireproof blocking plate 100 is the fireproof blocking plate 100 of any of the above embodiments, and the pipe is arranged in the through hole 1001.
[0048] Since the fireproof blocking plate 100 of the embodiment of the present disclosure has good reliability, the fireproof blocking assembly 1000 of the embodiment of the present disclosure has the advantages of good reliability, etc.
[0049] Optionally, the hole wall of the through hole 1001 and the pipe are filled with a first sealing member.
[0050] The first sealing member can include rock wool, sealant, etc.
[0051] By filling the first sealing member between the hole wall of the through hole 1001 and the pipe, the gap between the hole wall of the through hole 1001 and the pipe can be blocked, and the smoke or open flame entering the building room through the gap between the hole wall of the through hole 1001 and the pipe is avoided, thereby further improving the reliability of the fireproof blocking assembly 1000.
[0052] Optionally, the fireproof blocking assembly further includes a base body 200, the base body 200 has a mounting hole 2001, and the fireproof blocking plate 100 is mounted in the mounting hole 2001. The hole wall of the mounting hole 2001 and the edge of the fireproof blocking plate 100 are filled with a second sealing member.
[0053] The base 200 may be a wall, and the second sealing member may be an elastic fireproof caulking sealant. By filling the second sealing member between the wall of the mounting hole 2001 and the edge of the fireproof sealing plate 100, the gap between the wall of the mounting hole 2001 and the edge of the fireproof sealing plate 100 can be sealed, preventing smoke or open flames from entering the building through the gap between the wall of the mounting hole 2001 and the edge of the fireproof sealing plate 100, further improving the reliability of the fireproof sealing assembly 1000.
[0054] Optionally, the fireproof sealing plate 100 is connected to the base 200 via fasteners.
[0055] For example, the fireproof sealing plate 100 and the base 200 are connected by bolts, screws, etc.
[0056] The fireproof sealing plate 100 is connected to the base 200 by fasteners, which not only facilitates the installation and fixation of the fireproof sealing plate 100, but also improves the connection reliability between the fireproof sealing plate 100 and the base 200, and further improves the reliability of the fireproof sealing assembly 1000.
[0057] The fireproof sealing plate 100 of the present invention utilizes the phase change energy storage layer 3 to absorb heat during the phase change process, so that the first metal plate 1 and the second metal plate 2 are always in a safe temperature state, preventing the first metal plate 1 and the second metal plate 2 from being deformed due to temperature changes, and maintaining the integrity of the fireproof sealing. In addition, the temperature of the phase change energy storage material remains constant during the phase change process, thereby acting as a constant temperature bridge between the insulation layer 4 and the first metal plate 1. Most of the heat is absorbed by the phase change energy storage layer 3, thereby reducing the temperature deformation of the first metal plate 1. This solves the problem of rapid temperature rise of the fireproof sealing plate 100 in a short period of time, and allows the fireproof sealing plate 100 to be in a long-term constant temperature protection stage when a fire occurs in the outside world, helping the entire fireproof sealing assembly maintain its integrity and play a fireproof role.
