Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof rolling shutters, and particularly relates to a combined fireproof rolling shutter vertical scroll installation structure and a linear combined fireproof rolling shutter. Background Art

[0002] With the development of the scale of construction in my country, especially in recent years, there are more and more large-scale commercial complex projects. The fire partitions of such buildings are usually large-span, column-free, linear and transparent commercial spaces. Due to the large width of the openings of the fire partitions, in order to meet the requirements of installing fire shutters in the fire partitions, it is necessary to use more than two groups of single vertical fire shutters to form a linear combined fire shutter. At the same time, in order to ensure the fire resistance integrity and sealing and smoke-proof performance, the curtain surfaces of adjacent vertical fire shutters are usually overlapped by about 500 mm.

[0003] In actual installation applications, since adjacent vertical roller shutters need to overlap each other, the mounting brackets at both ends of the vertical roller shutters need to be installed in an offset manner. This requires a large installation width and height for the linear modular fire shutter. However, the ceiling is usually equipped with complex piping and bridge structures, so the installation space is limited. If the height space is insufficient, you can find ways to utilize the space below the ceiling, such as opening a hole in the ceiling to embed the vertical roller shutter's scroll part and then installing a decorative panel below the ceiling to block it. However, if the width space above the fire partition opening is insufficient due to interference from the piping and bridge structures, the linear modular fire shutter will directly fail to be installed. Therefore, it is urgent to improve the installation solution of the linear modular fire shutter for this situation. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the terms "height", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0032] Please also refer to Figures 1 to 6 The combined fireproof roller shutter vertical reel installation structure provided by the present invention is now described. The combined fireproof roller shutter vertical reel installation structure includes a plurality of first roller shutters 10 and second roller shutters 20 alternately distributed in a straight line; the first roller shutter 10 includes two first rollers 11, and two first fireproof curtains 12 respectively wound on the two first rollers 11; the second roller shutter 20 includes two second rollers 21, and two second fireproof curtains 22 respectively wound on the two second rollers 21; both ends of the two first rollers 11 are connected to the installation surface above the ceiling 30 through the first end plate 13, and both ends of the two second rollers 21 are connected to the installation surface through the second end plate 23; wherein the second end plate 23 is located below the first end plate 13, and the two first fireproof curtains 12 respectively extend downward from the outer sides of the two second rollers 21 and are sealed and overlapped with the curtain surfaces of the two second fireproof curtains 22 that are opposite to each other.

[0033] It should be noted that in this embodiment, guide rails are respectively provided on both sides of the fireproof opening opened on the fire wall of the fire partition, and the edge of the first fireproof curtain 12 or the second fireproof curtain 22 close to the guide rails extends into the guide rails and is vertically lifted and opened and closed under the constraint of the guide rails. Therefore, the above-mentioned first roller shutter 10 and the second roller shutter 20 are both vertical roller shutters.

[0034] The above-mentioned first roller shutter 10 and second roller shutter 20 have overlapping and crossing relationships due to the overlapping and sealing between the first fireproof curtain 12 and the second fireproof curtain 22. Therefore, the first reel 11 and the second reel 21 overlap and cross in the axial direction. In order to save the width space required for installation, the second end plate 23 is installed below the first end plate 13. At the same time, the first fireproof curtains 12 rolled up on the two first reels 11 enter the guide rail from both sides of the second end plate 23 and extend vertically downward. The second fireproof curtains 22 rolled up on the two second reels 21 overlap with the two first fireproof curtains 12 respectively and adhere tightly to achieve sealing, fireproofing and smokeproofing. This can avoid interference between the first curtain and the second end plate 23 in the intersection area of ​​the first roller shutter 10 and the second roller shutter 20.

[0035] Compared with the prior art, the vertical roller installation structure of the combined fireproof roller shutter provided in this embodiment installs the first end plate 13 above the second end plate 23, so that the two first fireproof curtains 12 extend downward from both sides of the second end plate 23 to form an overlapping sealing method with the first fireproof curtain 12 outside and the second fireproof curtain 22 inside, so that the first roller 11 and the second roller 21 form an upper and lower staggered vertical structure in the cross-over overlap area of ​​the first roller shutter 10 and the second roller shutter 20, thereby reducing the overall installation width occupied by the linear combined fireproof roller shutter, thereby meeting its installation application requirements in locations with narrow width spaces.

[0036] In some embodiments, see Figures 3 to 6 A first driving member 14 is connected to one of the first end plates 13 of the first rolling curtain 10, and the first driving member 14 is used to drive the two first rollers 11 to rotate in the same direction or in opposite directions; a second driving member 24 is connected to one of the second end plates 23 of the second rolling curtain 20, and the second driving member 24 is located between the two second rollers 21 and is used to drive the two second rollers 21 to rotate in the same direction or in opposite directions.

[0037] Here, the first drive member 14 and the second drive member 24 are both rolling door machines for fireproof rolling shutters and transmission mechanisms matched with the rolling doors that meet the supporting standards of GB14102. During specific installation, if the first drive member 14 is set on the first end plate 13 at the intersection of the first rolling shutter 10 and the second rolling shutter 20, the second drive member 24 is set on the second end plate 23 away from the first drive member 14. This can avoid the first drive member 14 and the second drive member 24 being set at the intersection of the first rolling shutter 10 and the second rolling shutter 20 at the same time, which increases the difficulty of installation. It is also beneficial to avoid the first drive member 14 and the second drive member 24 from interfering with each other.

[0038] As a specific embodiment of the first driving member 14, please refer to Figure 3 and Figure 4The first drive element 14 includes a first roller shutter mechanism 141, two first synchronous sprockets 142, and a first transmission chain 143. The first roller shutter mechanism 141 is mounted on the first end plate 13, with a first drive sprocket 1411 mounted on its output end. The two first synchronous sprockets 142 are mounted on the same end of the two first reels 11. The first transmission chain 143 is mounted on the first drive sprocket 1411 and meshes with the two first synchronous sprockets 142, allowing the two first synchronous sprockets 142 to rotate in the same or opposite directions, driven by the first drive sprockets 1411. The use of a chain drive improves transmission stability and allows the first transmission chain 143 to rotate in the same or opposite directions by varying the meshing method between the first synchronous sprockets 142 and the first synchronous sprockets 142, thereby increasing installation flexibility.

[0039] Alternatively, as Figure 3 As shown, in this embodiment, the first end plate 13 is located between the two first rollers 11 and extends downward to form a first boss 131, and the first roller door machine 141 is connected to the first boss 131; the first end plate 13 is located between the two first synchronous sprockets 142 and is rotatably connected to the tensioning wheel 132; the first transmission chain 143 and the two first synchronous sprockets 142 are both internally engaged, and the tensioning wheel 132 rolls the first transmission chain 143 over the first transmission chain 143.

[0040] By providing a first boss 131 for installing the first roller door machine 141, the first roller door machine 141 can be prevented from occupying the width space outside the two first rollers 11, thereby improving the compactness of the transmission structure; on this basis, considering that the first transmission chain 143 is simultaneously sleeved on the first driving sprocket 1411 and the two first synchronous sprockets 142 to form a triangular transmission path, the first transmission chain 143 is rolled downward by the tensioning wheel 132 to increase the wrap angle of the first transmission chain 143 to the two first synchronous sprockets 142, thereby avoiding the chain derailment between the first transmission chain 143 and the first synchronous sprocket 142 due to too few meshing teeth, thereby improving the transmission stability.

[0041] Another power transmission method of the first transmission chain 143 is as follows: Figure 4 As shown, a first guide wheel 133 is rotatably connected to the first end plate 13, and the first guide wheel 133 is located on the side of one of the first synchronous sprockets 142 away from the other first synchronous sprocket 142; wherein, the first transmission chain 143 is looped around the first guide wheel 133 to form an internal engagement, and the first transmission chain 143 is externally engaged with the first synchronous sprocket 142 close to the first guide wheel 133, and internally engaged with the other first synchronous sprocket 142.

[0042] It should be understood that the above-mentioned internal meshing refers to the state in which the sprockets are located inside the chain rings of the transmission chain and mesh with each other, and external meshing refers to the state in which the sprockets are located outside the chain rings of the transmission chain and mesh with each other. Therefore, if both sprockets are internally meshed with the transmission chain, they rotate in the same direction, and if the two sprockets are internally meshed and externally meshed with the transmission chain respectively, the two sprockets rotate in opposite directions. In this embodiment, by providing a first guide wheel 133 on the outside of one of the first synchronous sprockets 142 to mesh with the first transmission chain 143, the first transmission chain 143 can be externally meshed by the lower edge of the first synchronous sprocket 142 near the first guide wheel 133, thereby achieving the internal meshing and external meshing of the two first synchronous sprockets 142 and the first transmission chain 143, respectively, thereby meeting the operating requirement that the first drive sprocket 1411 drives the two first synchronous sprockets 142 to rotate in opposite directions.

[0043] For some possible implementations, see Figure 5 and Figure 6 The second end plate 23 is located between the two second scrolls 21 and extends upward to form a second convex seat 231; the second driving member 24 includes a second rolling door machine 241, two second synchronous sprockets 242 and a second transmission chain 243; wherein, the second rolling door machine 241 is arranged on the second convex seat 231 and the output end is sleeved with a second driving sprocket 2411; the two second synchronous sprockets 242 are respectively sleeved on the same end of the two second scrolls 21; the second transmission chain 243 is sleeved on the second driving sprocket 2411 and is respectively meshed with the two second synchronous sprockets 242, so as to make the two second synchronous sprockets 242 rotate in the same direction or in the opposite direction under the drive of the second driving sprocket 2411.

[0044] By setting a second protrusion 231 for installing the second rolling door machine 241, the second rolling door machine 241 can be located between the two first fireproof curtains 12. The second rolling door machine 241 no longer occupies the width space outside the two second rollers 21, thereby improving the compactness of the transmission structure and avoiding friction interference between the second rolling door machine 241 and its transmission structure and the first fireproof curtains 12.

[0045] The second transmission chain 243 can be Figure 5The power transmission method shown is that the second transmission chain 243 and the two second synchronous sprockets 242 are both internally meshed. The second transmission chain 243 is simultaneously sleeved on the second drive sprocket 2411 and the two second synchronous sprockets 242 to form a triangular transmission path. Given the small spacing between the two second synchronous sprockets 242, there is no need to consider the wrap angle of the second transmission chain 243. This allows the two second synchronous sprockets 242 to rotate in the same direction. Since no additional guide wheels are required, this method is conducive to reducing the size of the second end plate 23, not only avoiding interference between the first fire curtain 12 and the second end plate 23, but also helping to minimize the installation width occupied by the overall structure.

[0046] The second transmission chain 243 can be Figure 6 The power transmission method shown is that the second end plate 23 is rotatably connected to a second guide wheel 232, and the second guide wheel 232 is located on the side of one of the second synchronous sprockets 242 away from the other second synchronous sprocket 242, wherein the second transmission chain 243 is looped around the second guide wheel 232 to form an internal engagement, and the second transmission chain 243 is externally engaged with the second synchronous sprocket 242 close to the second guide wheel 232, and internally engaged with the other second synchronous sprocket 242.

[0047] For the situation where two second reels 21 are required to reversely wind the two second fireproof curtains 22, a second guide wheel 232 is set on the outside of one of the second synchronous sprockets 242, and the second guide wheel 232 is internally engaged with the second transmission chain 243 to enable the second synchronous sprocket 242 close to the second guide wheel 232 to form an externally engaged connection transmission mode with the second transmission chain 243, thereby satisfying the transmission mode of internal and external engagement of the two second synchronous sprockets 242 with the second transmission chain 243 respectively, thereby realizing the reverse rotation of the two second reels 21, so that the second fireproof curtains 22 reversely wound on the two second reels 21 can be raised, lowered and reeled synchronously.

[0048] Please note that, see Figures 3 to 6 The first roller shutter 10 also includes two first supporting shafts 15, and the two first supporting shafts 15 are respectively rolled on the two first fireproof curtains 12; the second roller shutter 20 also includes two second supporting shafts 25, and the two second supporting shafts 25 are respectively rolled on the two second fireproof curtains 22; wherein, the overlapping positions of the first fireproof curtain 12 and the second fireproof curtain 22 are pressed against each other and sealed under the rolling pressure of the first supporting shafts 15 and the second supporting shafts 25.

[0049] On the one hand, in order to ensure that the two first fire curtains 12 can fall smoothly from the outside of the second end plate 23, the distance between the two first reels 11 needs to be greater than the two second reels 21. If the first fire curtain 12 and the second fire curtain 22 sag directly, they cannot be tightly fitted together, which will affect the overlapping sealing effect. On the other hand, since the lifting height change of the first fire curtain 12 and the second fire curtain 22 is directly related to the change of the winding radius of the two on the first reel 11 and the second reel 21, if the first fire curtain 12 and the second fire curtain 22 sag directly, they will be affected by the winding radius. The change will also affect the overlapping sealing between the two. In order to avoid the above problem, two first support shafts 15 and two second support shafts 25 are set to respectively block and constrain the first fire curtain 12 and the second fire curtain 22, so that the distance between the two first fire curtains 12 after unfolding downward and the distance between the two second fire curtains 22 after unfolding downward can remain stable, thereby improving the overlapping sealing reliability of the first fire curtain 12 and the second fire curtain 22, and ensuring the overall fire prevention performance and sealing and smoke proof performance between the adjacent first roller curtains 10 and the second roller curtains 20.

[0050] Based on the same inventive concept, combined Figures 1 to 6 It is understood that the embodiment of the present application also provides a linear combined fireproof roller shutter, including the above-mentioned combined fireproof roller shutter vertical roller shaft installation structure.

[0051] Compared with the prior art, the linear combined fireproof roller shutter provided in this embodiment adopts the above-mentioned combined fireproof roller shutter vertical roller installation structure. By installing the first end plate 13 above the second end plate 23, the two first fireproof curtains 12 extend downward from both sides of the second end plate 23 to form an overlapping sealing method with the first fireproof curtain 12 outside and the second fireproof curtain 22 inside, so that the first roller 11 and the second roller 21 form an upper and lower staggered vertical structure in the cross-over overlap area of ​​the first roller shutter 10 and the second roller shutter 20, thereby reducing the overall installation width occupied by the linear combined fireproof roller shutter, thereby meeting its installation application requirements in locations with narrow width spaces.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
