[0025] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.
[0026] Figure 1 Schematic diagram of the structure of the fire barrier according to the embodiment of the present application is shown. Figure 1As shown, the fire barrier plate includes: a plurality of fire barrier sheets 110, the plurality of fire barrier sheets 110 are connected in sequence and adjacent fire barrier sheets 110 are arranged at an angle so that the plurality of fire barrier sheets 110 form a fire barrier plate body 100 with a wavy structure; a plurality of perforations are regularly arranged on the fire barrier sheet 110, and the plurality of perforations include at least a first perforation 111 and a second perforation 112, and the shapes of the first perforation 111 and the second perforation 112 are different.
[0027] In the embodiment of the present application, multiple fire-blocking sheets 110 form a wavy-structured fire-blocking plate body 100. Fire spreads through the multiple perforations of the first fire-blocking sheet 110A of the fire-blocking plate body 100. Because adjacent fire-blocking sheets 110 are arranged at an angle, fire spreads from the multiple perforations of the first fire-blocking sheet 110A to the next adjacent fire-blocking sheet 110, and then to the last fire-blocking sheet 110C.
[0028] In the embodiments of the present application, multiple perforations are regularly arranged on the fire barrier sheet 110. When a fire passes through the multiple perforations on the fire barrier sheet 110, the fire intensity passing through the perforations is regular, and the fire intensity reflected back by the next adjacent fire barrier sheet 110 is also regular. This allows the fire to regularly pass through the multiple perforations of the multiple fire barrier sheets 110, making the transmitted and reflected fire intensity controllable. Multiple perforations can be arranged on each fire barrier sheet 110 to control the fire intensity transmitted and reflected by each fire barrier sheet 110, depending on the application scenario.
[0029] In one example, the plurality of fire-blocking sheets 110 may be integrally formed to form a fire-blocking plate body 100 with a wavy structure.
[0030] In the embodiment of the present application, the sizes and shapes of the plurality of fire barrier sheets 110 may be the same or different.
[0031] In one example, the plurality of fire-blocking sheets 110 are square in shape and have the same size and shape. The fire-blocking sheets 110 may be provided with chamfers or cut edges according to the requirements of the installation scenario.
[0032] In one example, the angles between two adjacent fire barrier sheets 110 can be the same or different. For example, the angles between two adjacent fire barrier sheets 110 can be set according to the needs of the fire transmission and reflection of the fire barrier sheets 110.
[0033] In one example, among the plurality of fire barrier sheets 110 , the angle between two adjacent fire barrier sheets 110 is the same, and the angle between two adjacent fire barrier sheets 110 is 100°-150°, for example, 120°.
[0034] In one example, the angle between two adjacent fire barrier sheets 110 and the shape of the perforations can be set according to the requirements of the fire transmission and reflection of the fire barrier sheet 110 .
[0035] In one example, the ratio of fire intensity transmitted and reflected by each fire barrier 110 can be the same or different. For example, the ratio of fire intensity transmitted and reflected by each fire barrier 110 can be set to be the same, with each fire barrier 110 transmitting 75% of the fire intensity through the perforations and reflecting 25% of the fire intensity back through the area outside the perforations. Based on the angle between two adjacent fire barrier sheets 110 and the arrangement of the multiple perforations, when a fire passes through the fire barrier 110, 75% of the fire intensity can be transmitted through the perforations, and 25% can be reflected back through the area outside the perforations.
[0036] In one embodiment, the fire barrier sheet 110 includes a first side 113 and a second side 114 that are arranged opposite to each other, the first perforation 111 is arranged near the first side 113, and the second perforation 112 is arranged near the second side 114. The fire barrier sheet 110 is connected to adjacent fire barrier sheets 110 through the first side 113 and the second side 114 respectively.
[0037] In one example, on the fire barrier plate body 100 , the side of the fire barrier sheet 110 close to the first side 113 of the first fire barrier sheet 110A is the first side 113 , and the side of the fire barrier sheet 110 away from the first side 113 of the first fire barrier sheet 110A is the second side 114 .
[0038] In one example, the first through-holes 111 of the plurality of fire-blocking sheets 110 have the same shape but different sizes or numbers; the first through-holes 111 of the plurality of fire-blocking sheets 110 have the same shape but different sizes or numbers.
[0039] In one example, the second through-holes 112 of the plurality of fire-blocking sheets 110 have the same shape but different sizes or numbers; the second through-holes 112 of the plurality of fire-blocking sheets 110 have the same shape but different sizes or numbers.
[0040] In one embodiment, the first through-holes 111 and the second through-holes 112 are arranged in an array on the fire-blocking plate 110. The plurality of through-holes arranged in an array can facilitate calculation or determination of the fire intensity transmitted or reflected by the fire-blocking plate 110.
[0041] In the embodiment of the present application, the first through-hole 111 and the second through-hole 112 can be through-holes of any shape, such as square holes, circular holes, hexagonal holes, triangular holes, diamond holes, heart-shaped holes, and teardrop-shaped holes.
[0042] In one example, the first perforation 111 is a large hole, which is the main perforation for transmitting fire; the second perforation 112 is a small hole, and multiple small second perforations 112 are distributed along the length of the fire barrier 110. Without blocking the transmission of fire, the size of the second perforations 112 can be controlled to reflect part of the fire back, and the fire can store heat after returning.
[0043] In one embodiment, the first through-hole 111 is a square hole, and the second through-hole 112 is a circular hole.
[0044] In one example, the number of square holes on each fire barrier sheet 110 is the same, for example, 2. The lengths of the square holes on each fire barrier sheet 110 can be the same or different. The widths of the square holes on each fire barrier sheet 110 can be different.
[0045] In one example, each fire barrier sheet 110 is provided with two square holes near the first side 113 of the fire barrier sheet 110 , and the two square holes are arranged in a row along the direction of the first side 113 .
[0046] In one example, the width of the square hole is determined according to the amount of fire that the fire barrier sheet 110 needs to transmit and reflect.
[0047] In one example, the fire barrier sheet 110 has a plurality of circular holes, which are arranged in an array.
[0048] In one embodiment, the plurality of first through-holes 111 are spaced apart along the direction of the first side 113 , and the plurality of second through-holes 112 are spaced apart and evenly distributed along the direction of the second side 114 .
[0049] In one example, the number of rows of circular holes on the multiple fire barrier sheets 110 varies. For example, the number of rows of circular holes on the multiple fire barrier sheets 110 can be one, two, or three rows. The number of rows of circular holes is determined based on the amount of fire that the fire barrier sheet 110 needs to transmit and reflect.
[0050] In one example, two adjacent rows of circular holes are arranged alternately. Specifically, for example, the circular holes in the second row are arranged relatively between the two circular holes in the first row, so that the fire can be evenly transmitted.
[0051] In one embodiment, along the arrangement direction of the plurality of fire barrier sheets 110 , the width of the first through-holes 111 on each fire barrier sheet 110 gradually narrows, and the number of the second through-holes 112 on each fire barrier sheet 110 gradually increases.
[0052] In one example, the widths of the plurality of fire barrier sheets 110 are the same, the width of the first perforations 111 on each fire barrier sheet 110 gradually narrows, and the number of the second perforations 112 on each fire barrier sheet 110 gradually increases, so that the transmitted fire intensity gradually decreases and the reflected fire intensity gradually increases until the last fire barrier sheet 110C of the fire barrier board body 100 reflects most of the fire back.
[0053] At the same time, the width of the first perforations 111 on each fire barrier sheet 110 gradually narrows, and the number of the second perforations 112 on each fire barrier sheet 110 gradually increases. Furthermore, the first perforations 111 and the second perforations 112 on two adjacent fire barrier sheets 110 can be staggered relative to each other. In other words, the first perforations 111 on the first fire barrier sheet 110A are opposite to the second perforations 112 on the second fire barrier sheet 110B, and are also opposite to a portion of the first perforations 111 on the second fire barrier sheet 110. This allows the fire transmitted from the first perforations 111 on the first fire barrier sheet 110A to pass through the opposite portion of the first perforations 111 on the second fire barrier sheet 110 and the second perforations 112 on the second fire barrier sheet 110B, with the plate between the second perforations 112 reflecting part of the fire back. The second perforations 112 of the first fire barrier 110A partially oppose the first perforations 111 of the second fire barrier 110B, allowing the majority of the fire transmitted by the second perforations 112 of the first fire barrier 110A to be transmitted. By staggering the first and second perforations 111, 112 of the two adjacent fire barrier sheets 110, the required amount of fire energy can be reflected without directly blocking the fire's transmission. This effectively and accurately controls the spread of fire without affecting its transmission.
[0054] In one embodiment, the fire-blocking plate further includes at least one mounting portion 200 , and the mounting portion 200 is connected to the fire-blocking sheet 110 at at least one end of the fire-blocking plate body 100 .
[0055] In one example, the fire barrier plate includes two mounting portions 200 , which are respectively connected to the front and rear ends of the fire barrier plate body 100 , so as to facilitate the installation and fixation of the fire barrier plate body 100 .
[0056] In one example, the plurality of fire-blocking sheets 110 have the same length, and the length of the mounting portion 200 is the same as that of the plurality of fire-blocking sheets 110 .
[0057] In one example, the width of the mounting portion 200 is smaller than the width of the fire barrier sheet 110 to prevent the mounting portion 200 from blocking the transfer of fire.
[0058] In one example, the width of the mounting portion 200 connected to the head end of the fire barrier plate body 100 , ie, connected to the first fire barrier sheet 110A among the plurality of fire barrier sheets 110 , is less than ½ of the width of the fire barrier sheet 110 .
[0059] In one example, the width of the mounting portion 200 connected to the head end of the fire barrier plate body 100 , ie, connected to the first fire barrier sheet 110A among the plurality of fire barrier sheets 110 , is smaller than the width of the first through hole 111 of the first fire barrier sheet 110 .
[0060] In the embodiment of the present application, the mounting portion 200 can be a sheet with perforations or a sheet without perforations, which can be selected according to the actual needs of the application and is not limited in the embodiment of the present application.
[0061] In one example, the mounting portion 200 is in the shape of a sheet without perforations, and the width of the mounting portion 200 is smaller than the width of the first perforation 111 of the first fire barrier sheet 110A.
[0062] In one example, the angle between the mounting portion 200 and the first fire barrier sheet 110A may be the same as the angle between two adjacent fire barrier sheets 110 when a plurality of fire barrier sheets 110 are connected.
[0063] In one example, the angle between the mounting portion 200 and the first fire barrier sheet 110A of the fire barrier board body 100 may be 110° to 160°, such as 130°, so as to minimize the possibility of blocking the fire from being transferred to the first fire barrier sheet 110A.
[0064] In one example, the angle between the mounting portion 200 and the last fire barrier sheet 110C of the fire barrier board body 100 can be 60°-120°, for example 80°; this can reduce the space occupied by the mounting portion 200 and reduce the spread of fire.
[0065] In the embodiment of the present application, the first fire barrier sheet 110A may refer to the fire barrier sheet 110 that is closest to the fire source in the direction of fire transmission, and the last fire barrier sheet 110C may refer to the fire barrier sheet 110 that is farthest from the fire source in the direction of fire transmission.
[0066] In the embodiment of the present application, at least one mounting portion 200 is provided with a connector 201 for mounting.
[0067] In one embodiment, the plurality of fire barrier sheets 110 and the mounting portion 200 are integrally formed.
[0068] In one embodiment, the fire barrier sheet 110 is made of stainless steel.
