[Previous technology] In China's current fire protection laws and regulations, there are relevant provisions on the performance of smoke control systems required for buildings in the event of a fire. This part is mainly found in "Setting Standards for Fire Protection Equipment in Various Places" 18 " The bar contains the design area of the smoke prevention area, the depth of the smoke prevention vertical wall, the position of the smoke exhaust port, and the amount of smoke exhaust. The meaning of "smoked smoke control" is mainly to separate the dense smoke generated from the fire scene. 、 Limited in a certain area, or change the flow direction and concentrated elimination of dense smoke to control the spread and spread of deadly smoke in the fire field, extend the escape gold time, and maintain the clearness of the escape channel to the benefit of personnel Prompt evacuation or stand-by, and follow-up rescues. In the smoke prevention plan, the main use of smoke prevention vertical wall or smoke curtain device. In China's current building technical regulations, all types of buildings should be provided with smoke-proof vertical walls. Among them, the smoke-proof vertical walls (built for non-combustible materials) of general buildings should be suspended from the ceiling by more than 50 cm. Referring to Figure 1, it is a commonly-used fixed smoke-prevention vertical wall 1. It is suspended and fixed on the ceiling, and the smoke storage space formed by the sag distance is used for smoke storage control to prevent the smoke from flowing around and spreading in the fire field. . However, the biggest shortcoming of the fixed smoke-proof vertical wall 1 is that it will destroy the elevated landscape design inside the building, and affect the bright and open space perception of the building. For M253371, since the sag depth of smoke-proof sag walls of various types of buildings has been clearly stated, if a fixed smoke-proof sag wall with an inappropriate sag depth is constructed in the place, for example, the sag depth is too shallow, its smoke storage function Poor, it is difficult to exert the effect of dense smoke separation. For example, if the pendant is too deep, it will cause a sense of spatial pressure on the person. This will affect the operation of the person, and it will affect large machines during the transportation. Caused by obstacles' is not conducive to the planning of space placement of other machinery and equipment. Refer to Figure 2, which is a common smoke-prevention curtain 2 that is stored in the ceiling when not in use. When a fire occurs, it will start automatically and hang down from the ceiling to prevent the smoke from spreading in the fire field. ·-Even if this type of smoke-proof curtain 2 is hidden in normal time, it will not affect the beauty of the building wall and the sight of people, but it can improve the fixed smoke-proof vertical wall i (see figure i), destroy the landscape design, and easily cause obstacles to the transportation of objects. Etc. However, due to the motor drive mechanism of the smoke-proof drape 2, the smoke-proof drape 2 usually has a small span of 15 spans, and must be divided into multiple segments before being arranged adjacently or partially overlapping. In order to make the smoke-proof drape 2 as a whole have a seam and an edge overlap, the smoke can easily escape through the gap formed by the seam and the overlap, and the overall effect of the dense smoke segment is not good. 'Additionally', as mentioned earlier, the smoke-prevention curtain 2 is driven by a motor to achieve an automatic descent effect of 20. In order to ensure that the smoke-prevention curtain 2 is activated immediately when a fire occurs, it is used for the droop-drive. Motor-related equipment must be set to 'monthly compliance and maintenance', which will increase the overall maintenance cost. [New content] Therefore, the purpose of this new model is to provide a small hidden 5 M253371 design, which can maintain the building landscape and its spatial configuration and use, and has a large extension span and excellent smoke prevention. Anti-smoke curtain device for smoke effect. Therefore, the novel smoke-prevention curtain device is arranged on a ceiling located in one of the two building walls. The smoke-proof drape device includes a fixed shell seat fixed to the sky and flower plate and having a lower opening, a movable door panel pivotably arranged at the opening under the fixed shell seat, a positioning unit, A pushing unit and a curtain unit arranged in the fixed shell seat. The movable door panel has a pivotal end 'which is pivotally connected to the open mouth below the fixed shell seat, and a lug which is detachably positioned opposite the pivoted end to the fixed shell seat. end. The positioning unit is used to make the movable door panel-

The vertical curtain unit has a reel fixed inside the fixed shell seat, a smoke-proof vertical curtain that is expandably wound on the reel, and a heavy piece fixed on one end of the smoke-proof vertical curtain away from the reel. The weight is detachably received on the movable door panel. When the swinging end of the movable door panel leaves the opening under the fixed shell seat and swings downward, the _ heavy part performs a free-fall movement and falls out of the fixed shell seat, and is pulled down with the smoke-proof curtain Lowered into an expanded state. I The effect of this new model is to use the vertical curtain unit to be concealed in a small volume of the fixed shell seat when not in use. The overall aesthetics are good, and it is conducive to the space planning of other utensils. In addition, the smoke-prevention curtain has a single structure: it has a large extension span, which can effectively block thick smoke, and the overall smoke-prevention effect is good. [Embodiment] 6 M253371 The foregoing and other technical contents, features, and effects of the new model will be clearly understood in the following detailed description of one of the Chevuya embodiments with reference to the drawings. Referring to FIG. 3 and FIG. 4, this preferred embodiment of the novel smoke-prevention curtain device 5 is provided on a daylight board 4 between two spaced-apart walls 3 (for example, beams and pillars), and can be subjected to The smoke detector (not shown) of a fire alarm system is linked. The smoke-proof drape device 5 includes a long-shaped fixed housing seat 51 fixed on the ceiling 4 and having a lower opening 511, and an open opening 511 pivotably located below the fixed housing seat 51. A movable door panel 52, a ... position unit 53, a push unit 54, a vertical curtain unit 55 provided in the fixed shell seat 51, and two guides provided directly on the surface of the two building walls 3, respectively. Slot pieces 5 6. The fixed casing base 51 has a rectangular upper casing wall portion 512 fixed to the ceiling 4 and two side casing wall portions 513. The two side shell wall portions 513 extend vertically downward from the opposite side edges of the upper shell wall portion 512, respectively, and are orthogonal to the surface of the two building walls 3. On the opposite side of the shell wall portion 513 on each side, the trimmer corresponds to the surface of the one wall 3. In this embodiment, the height of the two-side shell wall portion 513 is about five to ten centimeters. "The δ-xuan movable door plate 52 is arranged along the length direction of the fixed shell base 51 and has a rectangular long plate shape. The movable door plate 52 has a bottom shell wall portion 513 pivotally connected to one of the fixed shell bases 51 A pivot end 521 at the edge, and a swing end 522 opposite to the pivot end 521 and detachably positioned at the bottom edge of the other side wall portion 513. 7 M253371 See FIG. 4 and FIG. 5, the positioning unit 53 has a first positioning member 531 provided at a plurality of intervals on the swing end 522 of the movable door panel 52, and a second position provided at a plurality of intervals at the bottom edge of the shell wall portion 513 of the fixed housing seat 51 corresponding to the swing end 522 Positioning member 532. The majority of the first and second positioning members 531.5 and 532 respectively correspond to each other. The first and second positioning members 531 and 532 can generate an adsorption effect, so that the swinging end 522 of the movable door panel 52 can be adsorbed and positioned. At the bottom edge of the corresponding side shell wall portion 513 (as shown in Figure 4). In this embodiment, the first positioning member 531 is a metal piece, and the second positioning member 532 is a magnetic block. The two positioning members 53 丨 and 532 can be attracted together by the magnetic attraction spring ·· 10. The pusher unit 54 has a plurality of hydraulic cylinders 541 that can be linked by the smoke detection sensor. The majority of the hydraulic cylinders 541 are fixed to the fixed housing 5 at a side that is vertically spaced from the side corresponding to the swing end 522 of the movable door panel 52. The housing wall portion 513 is partially hidden in the ceiling 4. The majority of the hydraulic cylinders 541 can act on the swinging end 522 of the movable door panel 52 when it is actuated at the same time, thereby lifting it. Corresponds to the adsorption effect between the first and second positioning members 53 丨 and 532. When the pushing effect of the swing end 522 is greater than the suction effect, the swing end 522 can be away from the corresponding side shell wall portion 5 丨 3 Since the operating mechanism of the hydraulic cylinder 541 belongs to the category of conventional mechanical principles, it will not be described in detail here. The vertical curtain unit 55 has a reel 5 5 fixed in the fixed housing 51. 1. It can be developed. A smoke-proof curtain 5 5 2 wound around the reel 5 51 and a weight 553 fixed to one end of the smoke-proof curtain 552 away from the reel 551 along its length. The smoke-proof curtain 552 has A distance away from the 8 M253371 reel 551 and wrapped around the heavy piece 553 The descent end 554. The weight 553 is detachably supported on the movable door panel 52, and the opposite ends thereof can be slid up and down in the two guide grooves 56 respectively. Ίο See FIG. 5 and FIG. 6. When the hydraulic cylinder 541 of the pushing unit 54 pushes against the swinging end 522 of the movable door panel 52, so that the first and second positioning members 53 丨, 532 are separated from each other, the swinging end 522 of the movable door panel 52 is separated from the phase. Corresponding to the bottom edge of the side shell wall portion 513 of the fixed mounting base 51 and swinging downward away from the opening 511 below the fixed casing base 51, the heavy piece 553 performs a free fall motion and falls out of the fixed casing At the same time, the descent end 554 of the smoke-proof drape 552 is lowered along the length of the two guide grooves 56 by a predetermined distance (about 55 cm) at the same time to form a flat unfolded state. Wherein, when the heavy field 553 of the β β-heavy link descents the descent end 554 to the predetermined distance, the heavy part 553 abuts the bottom end of the two guide grooves 56. 15 20 When a fire occurs, the smoke detection sensor of the fire alarm system detects the thick smoke, and then most of the hydraulic cylinders 541 of the pushing unit 54 are actuated together, thereby pushing the swinging end 522 of the movable door panel 52 to disengage. The bottom edge of the side shell wall portion 513 of the corresponding shell base 5 is fixed correspondingly, and the movable door panel 52 swings downward. At this time, the heavy piece 553 loses the support function originally received by the movable door panel 52. That is, under the auxiliary limit of the two guide grooves 56, the free fall movement is performed to quickly fall vertically, and the smoke prevention curtain is linked. 552 descents quickly and synchronously until the smoke-proof curtain 552 and the heavy piece 553 drop down to a predetermined distance (at this time, the heavy piece 553 is restrained and positioned at the guide groove piece = bottom end) and stops. Floating state. Therefore, the anti-smoke curtain 552 originally coiled and stored in the fixed seat 51 can be quickly hung down and unfolded into the path of dense smoke 9 M253371 to form a wall, effectively separating and blocking the dense smoke. It was then prevented from spreading to extend the escape time. Therefore, the smoke-proof drape device 5 can really exert the following advantages in assembly and use:. 5 1 · When not in use ', the smoke-proof drape 5 5 2 is hidden and stored in a small-volume fixed housing 51. Helps the aesthetic maintenance of the interior landscape of the building and the flexible use of space configuration: The smoke-proof drape 552 is concealed and stored in the small-volume fixed housing base 51 when not in use, because the fixed housing base fixed on the ceiling 4 The height of 0 51 is only about five to ten centimeters. The overall volume is small and the space consumed is very low. It will not affect the landscape design and visual perception of the interior of the building. The overall aesthetics is excellent; In the space layout planning, it will not cause obstacles to the transportation of large machinery and items, and can maintain the flexible use of space allocation. This can effectively improve the aesthetics of the ordinary fixed-type 5 smoke-proof vertical wall 1 (see Figure 1), and can easily affect the transportation of goods. 2. The smoke-proof vertical curtain 552 has a large extension span, and the overall smoke-proof effect is good: · The smoke-proof vertical curtain 552 is wound around the reel 551 as a whole, and the curtain is matched with the heavy piece 553 by using the scroll 551 The design, combined with the auxiliary limiting effect of the one guide groove member 56, can strengthen the stability of the smoke-proof drape 552 at the upper and lower ends during the descent process, so that the smoke-proof drape 552 has a single structure with a large extension span. In order to effectively prevent the thick smoke from channeling during descent, the overall smoke prevention effect is good, which effectively improves the general smoke prevention drape 552 (see Figure 2). It needs to be cut in multiple segments and has a small span, resulting in 10 joints and overlaps when connected. Gap, resulting in poor overall smoke prevention and other issues. 3. Under the auxiliary limit of the second guide groove member 56, effectively improve the smoothness of the smoke-proof vertical curtain 552: When the heavy piece 553 performs a free-fall movement and links the smoke-proof vertical curtain 552 downward, The auxiliary stop of the two guide grooves 56 can effectively improve the descent stability of the smoke-proof drape 552, thereby improving the smoothness of the overall descent, and promote the smoke-proof drape 552 to sag quickly. During the prime time of the field rescue, the smoke flow can be effectively blocked to exert excellent tobacco control results. 4. The maintenance cost is low: Because the smoke-proof curtain 552 is linked by the heavy piece 553 that performs free-fall movement, the acceleration drops, instead of the ordinary smoke-proof curtain 2 (see Figure 2). Constant-speed droop occurs, so it is not necessary to regularly perform maintenance and maintenance of the drive motor, which consumes high maintenance costs, as in the general smoke-prevention curtain 2, and the overall maintenance cost is relatively low. To sum up, the new type of smoke-proof drape 552 is hidden and stored in a small volume of the relatively small housing 51 when not in use. The overall aesthetics are good and it is conducive to the planning of the two rooms. Furthermore, the smoke-proof drape 552 It has a single structure and a large extension span. At the same time, it can be lowered steadily and rapidly, and the overall smoke prevention effect is good. Therefore, it can indeed achieve the purpose of this new model. However, the above are only the preferred embodiments of the new model, and the scope of the implementation of the new model cannot be limited by this, that is, the simple equivalent changes and modifications made according to the patent application of the new model and the content of the new specification. , All should still fall within the scope of this new patent. 11 M253371 [Schematic description] Figure 1 is a schematic diagram illustrating the use of a general fixed smoke-proof vertical wall on a ceiling; Figure 2 is a schematic diagram illustrating the use of a general smoke-proof vertical curtain hanging from a day flower and a board Fig. 3 is a schematic diagram of assembly, illustrating that a preferred embodiment of the novel smoke-proof curtain device is installed on a ceiling (when not in use); Fig. 4 is a structure of the preferred embodiment Schematic diagram; Fig. 5 is a diagram showing the state of use, one of the preferred embodiments of the present invention is a smoke-prevention drape; and Fig. 6 is a schematic structural diagram illustrating the use of the preferred embodiment.
