Description

[Technical Field]

[0001] The present invention relates to a hanging smoke barrier, and more particularly to a panel-type hanging smoke barrier composed of a non-combustible sheet and a panel frame surrounding the non-combustible sheet. [Background technology]

[0002] Traditionally, large commercial facilities (office buildings, department stores, etc.) have installed smoke barriers to prevent the movement of smoke that occurs on the ceiling in the event of a fire, thereby protecting the lives of office workers, store clerks, and visitors working inside. According to the Building Standards Act, buildings with a total floor area or number of staircases exceeding a certain level are required to install smoke barriers made of non-combustible materials, and many smoke barriers (also called partition barriers) have been installed.

[0003] These smoke barriers were originally made of glass, but in the event of an earthquake, broken glass could fall from the ceiling on shoppers fleeing the store, causing injuries to the head and other parts of the body. Therefore, non-flammable sheets began to be used instead of glass.

[0004] Examples of smoke barriers using non-combustible sheets include panel-type smoke barriers in which the non-combustible sheet is surrounded by a panel frame, and tension-type smoke barriers in which pulling devices are provided on both the left and right ends of the non-combustible sheet to apply tension and correct wrinkles and slack in the non-combustible sheet.

[0005] Among these, conventional examples of panel-type hanging smoke barriers are shown in Figures 6 and 7. The panel-type hanging smoke barrier 40 shown in Figure 6 has a rectangular non-combustible sheet 41 surrounded by a panel frame 42 consisting of frame members 42a, 42b, 42c, and 42d, and the corners connecting the ends of adjacent frame members are fixed with approximately L-shaped connecting members 44 and screws 45.

[0006] In addition, the panel-type smoke-proof vertical wall 50 shown in Figure 7 is made up of a rectangular non-combustible sheet 51 surrounded by a panel frame 52 consisting of frame members 52a, 52b, 52c, and 52d, and the corner portions connecting the ends of adjacent frame members are fixed with pins 55.

[0007] Furthermore, Patent Document 1 describes an invention relating to a connecting structure for rectangular panel-type hanging smoke barriers that reliably prevents the movement of smoke generated in the event of a fire and that is aesthetically pleasing. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Utility Model Registration No. 3227037 Summary of the Invention [Problem to be solved by the invention]

[0009] As mentioned above, conventional panel-type hanging smoke barriers are rectangular in shape, with a rectangular non-combustible sheet surrounded by a panel frame. However, depending on the facility where the hanging smoke barrier is to be installed, the ceiling may be inclined or the ceiling rails that suspend the hanging smoke barrier may be curved due to design requirements. In such cases, a simple rectangular panel-type hanging smoke barrier cannot be used and various shapes are required, but because the angles of the corners vary, connecting members of different shapes are required to match.

[0010] The present invention solves the above-mentioned conventional problems and provides a panel-type smoke barrier that can be formed into various shapes depending on the installation location using common connecting members. [Means for solving the problem]

[0011] In order to solve the above problems, the panel-type smoke-proof hanging wall of the present invention is a panel-type smoke-proof hanging wall composed of a non-combustible sheet and a panel frame surrounding the non-combustible sheet, wherein the panel frame comprises a plurality of frame members arranged on the peripheral edge of the non-combustible sheet and connecting members attached to corner portions that connect the ends of adjacent frame members, and the connecting members have bending portions that allow the angle to be changed along the corner portions.

[0012] Preferably, at least one of the plurality of frame members is curved.

[0013] Preferably, the connector further comprises a decorative member covering the connecting member. [Effects of the Invention]

[0014] The panel-type hanging smoke barrier of the present invention is composed of a non-combustible sheet and a panel frame surrounding the non-combustible sheet. The panel frame comprises a plurality of frame members arranged around the periphery of the non-combustible sheet and connecting members attached to the corners connecting the ends of adjacent frame members, and the connecting members have bending parts that allow the angle to be changed along the corners. Therefore, by changing the angle of the bending parts of the connecting members, corners of various angles can be connected, and panel-type hanging smoke barriers of various shapes can be formed in combination with the frame members.

[0015] Furthermore, if at least one of the plurality of frame members is curved, it can also accommodate a curved ceiling rail that suspends the hanging smoke barrier.

[0016] Furthermore, when a decorative member is provided to cover the connecting member, the connecting member can be hidden to provide a neat finish.

[0017] In this way, according to the present invention, it is possible to provide a panel-type hanging smoke barrier that can be formed into various shapes according to the conditions of the installation location using a common connecting member. [Brief explanation of the drawings]

[0019] Next, a panel-type hanging smoke barrier according to an embodiment of the present invention will be described with reference to Figures 1 to 5. The panel-type hanging smoke barrier according to this embodiment is composed of a non-combustible sheet and a panel frame surrounding the non-combustible sheet, and is hung from a ceiling rail installed on the ceiling.

[0020] FIG. 1 is a perspective view showing the installation state of a panel-type hanging smoke barrier 100 according to this embodiment, and FIG. 2 is a cross-sectional view taken along line aa in FIG.

[0021] The ceiling of the facility is fitted with multiple joists 2, and ceiling rails 3 are attached to the underside of the joists 2 to suspend panel-type hanging smoke barriers 100 via ceiling boards 1. Due to requirements of the facility's design, the ceiling boards 1 are inclined at an angle, and the ceiling rails 3 are also curved.

[0022] A ceiling rail cover 5 is attached to the ceiling rail 3. The panel-type hanging smoke barrier 100 is attached to the ceiling rail 3 by a panel hook 6 attached to the panel-type hanging smoke barrier 100.

[0023] The panel-type smoke barrier 100 is composed of a non-combustible sheet 101 and a panel frame 102 that surrounds the non-combustible sheet 101. The side surfaces of the panel frame material 102 are covered with decorative members 103.

[0024] 1 has various shapes according to the slope of the ceiling board 1 and the curve of the ceiling rail 3, and the panel-type hanging smoke barrier 100 (reference numeral 100) is a general term for panel-type hanging smoke barriers of various shapes. The panel-type hanging smoke barriers of various shapes will be described in detail below.

[0025] (Embodiment 1) 3 is an assembly diagram showing the panel-type hanging smoke barrier 10 according to embodiment 1. The panel-type hanging smoke barrier 10 is composed of a non-combustible sheet 11 and a panel frame 12 that surrounds the non-combustible sheet 11. The non-combustible sheet 11 is substantially in the shape of a parallelogram.

[0026] The panel frame 12 consists of four frame members 12a, 12b, 12c, and 12d and four connecting members 14. The four frame members 12a, 12b, 12c, and 12d are arranged around the periphery of the non-combustible sheet 11, and more specifically, the non-combustible sheet 11 is attached to one side of each frame member without wrinkles. Therefore, like the shape of the non-combustible sheet 11, the panel frame 12 is also a roughly parallelogram in plan view.

[0027] The connecting members 14 are attached to the four corners that connect the ends of adjacent frame members, connecting the adjacent frame members. Because the panel frame 12 is a substantially parallelogram, two of the four corners (top right and bottom left in Figure 3) have acute angles and two (top left and bottom right in Figure 3) have obtuse angles.

[0028] The connecting member 14 is a plate-shaped member made of, for example, stainless steel, and has a bent portion in the middle. By bending this bent portion along the corners, the connecting member 14 can be attached to match the angle of each corner. It is preferable that the width of the connecting member 14 is approximately the same as the width of the side surface of the frame member.

[0029] The frame members and connecting members 14 are fixed together by first abutting the inside of connecting member 14 bent from the outside of the corner, and then screwing screws 15 into the frame members from the outside of connecting member 14 in a direction that penetrates the side of the frame members. By fastening with screws from the side in this way, the width of the side of frame members 12a, 12b, 12c, 12d and the width of connecting member 14 can be made the minimum width that allows for screw fastening, making it possible to make the entire frame thinner and lighter.

[0030] Furthermore, it is preferable to attach decorative members 13a, 13b, 13c, and 13d that cover connecting member 14. The decorative members can be attached so as to cover connecting member 14 from the entire front, back, and side surfaces of panel frame 12, or can be attached so as to cover connecting member 14 from only a portion of the front, back, and side surfaces of panel frame 12.

[0031] As a result of the above, the panel-type hanging smoke barrier 10 having a substantially parallelogram shape in plan view is completed.

[0032] (Embodiment 2) 4 is an assembly diagram showing a panel-type hanging smoke barrier 20 according to embodiment 2. The panel-type hanging smoke barrier 20 is composed of a non-combustible sheet 21 and a panel frame 22 that surrounds the non-combustible sheet 21. The non-combustible sheet 21 is substantially rectangular.

[0033] The panel frame 22 is made up of four frame members 22a, 22b, 22c, and 22d and four connecting members 24. The four frame members 22a, 22b, 22c, and 22d are arranged around the periphery of the non-combustible sheet 21, and more specifically, the non-combustible sheet 21 is attached to one surface of each frame member without wrinkles. Therefore, like the shape of the non-combustible sheet 21, the panel frame 22 is also generally rectangular in plan view.

[0034] The connecting members 24 are attached to the four corners that connect the ends of adjacent frame members, and connect the adjacent frame members. Because the panel frame 22 is approximately rectangular, all four corners are right angles.

[0035] The connecting member 24, the fixing of the frame member to the connecting member 24, and the decorative members 23a, 23b, 23c, and 23d are the same as those in embodiment 1, and therefore will not be described again. As a result, the panel-type vertical smoke barrier 20 having a substantially rectangular shape in plan view is completed.

[0036] (Embodiment 3) 5 is an assembly diagram showing a panel-type hanging smoke barrier 30 according to embodiment 3. The panel-type hanging smoke barrier 30 is composed of a non-combustible sheet 31 and a panel frame 32 that surrounds the non-combustible sheet 31. The non-combustible sheet 31 is approximately rectangular and curved.

[0037] The panel frame 32 is made up of four frame members 32a, 32b, 32c, and 32d and four connecting members 34. The four frame members 32a, 32b, 32c, and 32d are arranged around the periphery of the non-combustible sheet 21, and more specifically, the non-combustible sheet 31 is attached to one side of each frame member without wrinkles. Therefore, like the shape of the non-combustible sheet 31, the panel frame 32 is also curved and has a generally rectangular shape in a plan view. That is, the upper frame member 32a and the lower frame member 32b are curved.

[0038] The connecting members 34 are attached to the four corners that connect the ends of adjacent frame members, and connect the adjacent frame members. Because the panel frame 32 is approximately rectangular, all four corners are right angles.

[0039] The connecting member 34, the fixing of the frame member to the connecting member 34, and the decorative members 33a, 33b, 33c, and 33d are the same as those in embodiment 1, and therefore will not be described again. As a result, a curved panel-type vertical smoke barrier 30 that is generally rectangular in plan view is completed.

[0040] The connecting members 14, 24, 34 in the above embodiments can be used as common members because they can be adapted to corners of various angles by bending the middle portions.

[0041] The panel-type vertical smoke barrier walls 10, 20, 30 according to this embodiment are composed of non-combustible sheets 11, 21, 31 and panel frames 12, 22, 32 surrounding the non-combustible sheets. The panel frames 12, 22, 32 are composed of a plurality of frame members arranged around the periphery of the non-combustible sheets 11, 21, 31 and connecting members 14, 24, 34 attached to the corners connecting the ends of adjacent frame members. The connecting members 14, 24, 34 have bending portions that allow the angle to be changed along the corners. Therefore, by changing the angle of the bending portions of the connecting members 14, 24, 34, corners of various angles can be connected, and the panel-type vertical smoke barrier walls 10, 20, 30 can be formed in various shapes in combination with the frame members.

[0042] Furthermore, if at least one of the plurality of frame members is curved, it can also be adapted to a case where the ceiling rail 3 that suspends the hanging smoke barrier wall 30 is curved.

[0043] Furthermore, when decorative members 15, 25, and 35 that cover the connecting members 14, 24, and 34 are provided, the connecting members 14, 24, and 34 can be hidden to achieve a neat finish.

[0044] In this way, the panel-type hanging smoke barrier according to this embodiment can be formed into various shapes according to the conditions of the installation location using common connecting members.

[0045] Although the panel-type hanging smoke barrier according to the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various other modifications are possible.

[0046] For example, the shape of the fire-retardant sheet and panel frame may be a rhombus, a trapezoid, another quadrangle, or a polygon other than a quadrangle. There is also no limitation on the number of frame members. [Explanation of symbols]
