[0002] Smoke curtains are vertical partitions installed under or hidden within ceilings or floors. They are typically designed as wall structures that hang down a certain height from the top. In the event of a fire, they prevent the horizontal flow of smoke and hot gases. They are usually made of non-combustible materials and are a primary measure for dividing smoke control zones.
[0003] In existing technologies, glass plates are usually used as the main body of smoke curtains, and the smoke curtains are suspended on the Tianma rail groove by vertical screws. Smoke curtains made of glass plates are brittle and have the possibility of breakage, which results in insufficient safety and reliability. In addition, they are inconvenient to operate during installation and pose significant safety hazards. Utility Model Content

[0007] An edge-finishing assembly extends along the first direction and is disposed at the bottom of the side panel, and is respectively connected to the bottom of a plurality of color steel plates corresponding to the side panel; and
[0008] Multiple sets of connecting screws are respectively located between each pair of adjacent color steel plates; one end of the connecting screw is connected to the edge trimming assembly, and the other end extends upward in the vertical direction to be fixed on the ceiling track.
[0009] In one possible implementation, each of the color steel plates is provided with an annular edge trim at its end, and the edge trim has an arc-shaped structure with the center concave inward.
[0010] In the first direction, the edge trims of two adjacent color steel plates form a recessed space at the center that extends vertically and has a rectangular cross-section; the connecting thread rod passes through the recessed space.
[0011] In some embodiments, in the first direction, an adhesive layer is filled between the edge frames of two adjacent color steel plates.
[0012] For example, a central aluminum component is provided in the clearance space. The central aluminum component is sleeved on the outer peripheral wall of the connecting screw and fixed to the closing frame on both sides respectively.
[0013] In some embodiments, the centrally located aluminum component includes:
[0014] A square tube extends vertically within the clearance space and is arranged around the outer edge of the connecting screw.
[0015] Two end plates are symmetrically arranged on both sides of the square tube perpendicular to the first direction; the two end plates extend out of the clearance space in a direction away from each other and pass between the two adjacent closing frames.
[0016] In one possible implementation, the edge-recovery component includes:
[0017] A connecting steel plate is provided, extending along the first direction, and abutting against the bottom of a plurality of color steel plates corresponding to the side plate;
[0018] The lower ends of multiple sets of connecting screws pass through the connecting steel plate and are fixed by mounting nuts.
[0019] In some embodiments, the bottom of the connecting steel plate is provided with a finishing plate extending along the first direction; the two ends of the finishing plate are bent upward to form an upward-opening U-shaped structure, and abut against and fix to the two side plates of the side plate.
[0020] In some embodiments, in the horizontal direction perpendicular to the first direction, both ends of the connecting steel plate are respectively provided with downwardly bent edge structures, and the lower end of the bent edge structure abuts against the bottom of the U-shaped groove of the edge-receiving plate.
[0021] For example, the folded edge structure includes a first folded edge portion, a second folded edge portion, and a third folded edge portion connected in sequence; the first folded edge portion extends downward from the end of the connecting steel plate; the second folded edge portion extends horizontally at the lower end of the first folded edge portion; and the third folded edge portion is vertically fixed upward at the extension end of the second folded edge portion.
[0022] In one possible implementation, two sets of side panels are arranged in parallel in a horizontal direction perpendicular to the first direction, and a set of edge-trimming components is provided at the bottom of each set of side panels; a bottom plate is provided at the bottom of the two sets of side panels, and the bottom plate extends along the first direction; the two ends of the bottom plate are respectively connected to the two sets of edge-trimming components, so that the bottom plate and the two side panels form a box-shaped structure.

[0031] For ease of understanding, this application uses the appendix. Figure 2 The direction indicated by the middle arrow A is used to indicate the first direction.
[0032] Please refer to the following: Figure 1 and Figure 2 The smoke curtain system provided by this utility model will now be described. The smoke curtain system includes a side plate 1, an edge trimming assembly 2, and multiple sets of connecting screw rods 3; the side plate 1 is used to abut against the bottom of the suspended ceiling and extends downward in the vertical direction; the side plate 1 includes multiple sequentially connected color steel plates 11; the sequential connection direction of the multiple color steel plates 11 is defined as the first direction; the edge trimming assembly 2 extends along the first direction and is disposed at the bottom of the side plate 1, and is respectively connected to the bottom of the multiple color steel plates 11 corresponding to the side plate 1; the multiple sets of connecting screw rods 3 are respectively disposed between each pair of adjacent color steel plates 11; one end of the connecting screw rod 3 is connected to the edge trimming assembly 2, and the other end extends upward in the vertical direction for fixing to the ceiling track 4.
[0033] It should be understood that the direction in which the multiple color steel plates 11 are connected in sequence is the extension direction of the smoke curtain. Therefore, this first direction also indicates the extension direction of the smoke curtain.
[0034] Specifically, the suspended ceiling includes a keel frame 7 and a blind plate placed between the keels. The upper end of the connecting threaded rod 3 passes through the tianma rail groove 4 and goes upward into the keel, and is fixed by screwing nuts to hang the side plate 1 and the edge trim assembly 2 on the suspended ceiling.
[0035] Compared with the prior art, the smoke curtain system provided by this utility model uses color steel plate 11 instead of traditional glass plate structure. The raw materials are widely available and easy to obtain, and the weight is lighter, making it easy to hang. Multiple color steel plates 11 are supported and fixed by edge trimming components 2 to enhance the bottom support stability of multiple color steel plates 11. The side plates 1 of the color steel plate 11 structure can be conveniently suspended on the top track trough by connecting screw rods 3. During the installation of connecting screw rods 3, the color steel plate 11 is less likely to break, which can eliminate the safety hazards during the installation and use of the smoke curtain. The installation structure is stable and reliable and easy to operate.
[0036] Please see Figure 2In some possible embodiments, each color steel plate 11 is provided with an annular edge frame 111 at its end, and the edge frame 111 has an arc-shaped structure with the center concave inward; in the first direction, the edge frames 111 of two adjacent color steel plates 11 form a clearance space 12 that extends vertically and has a rectangular cross-section at the center concave; a connecting thread rod 3 is inserted in the clearance space 12.
[0037] To ensure the connection strength of the color steel plate 11, an annular edge trimming frame 111 is provided on the outer edge of the color steel plate 11; the color steel plates 11 are connected sequentially through the edge trimming frame 111 to form the side plate 1. At the same time, the two interconnected edge trimming frames 111 form the aforementioned clearance space 12 at the center, which allows the connecting threaded rod 3 to be easily inserted, so that the connecting threaded rod 3 clamps the bottom edge trimming assembly 2 and the ceiling to the middle side plate 1, thereby suspending the side plate 1.
[0038] Please see Figure 2 In some embodiments, in the first direction, an adhesive layer 6 is filled between the edge frames 111 of two adjacent color steel plates 11.
[0039] To facilitate the connection of two adjacent sets of color steel plates 11, sealant is filled between the edge trims 111 of two adjacent color steel plates 11 to form an adhesive layer 6, thereby connecting the two edge trims 111 to fix the two adjacent color steel plates 11.
[0040] Specifically, the center of the bow-shaped frame 111 forms the aforementioned clearance space 12, and the two ends are connected to each other by an adhesive layer 6.
[0041] Please see Figure 2 For example, a central aluminum component 5 is provided in the clearance space 12. The central aluminum component 5 is sleeved on the outer peripheral wall of the connecting screw 3 and fixed to the side frame 111 respectively.
[0042] By setting the central aluminum component 5, the connecting screw 3 can be limited within the central aluminum component 5, preventing the connecting screw 3 from shaking significantly within the clearance space 12, which would affect the stability of the side plate 1 during hoisting.
[0043] Please see Figure 1 In some embodiments, the central aluminum component 5 includes a square tube 51 and two end plates 52; the square tube 51 extends vertically within the clearance space 12 and is arranged around the outer edge of the connecting screw 3; the two end plates 52 are symmetrically arranged on both sides of the square tube 51 perpendicular to the first direction; the two end plates 52 extend out of the clearance space 12 in a direction away from each other and pass between two adjacent frame frames 111.
[0044] Specifically, the square tube 51 is used to surround the outside of the connecting screw 3 to prevent the connecting screw 3 from shaking significantly; the two end plates 52 are used to limit the connection within the side frame 111 to ensure the limiting of the central aluminum part 5.
[0045] Specifically, the two surfaces of each end plate 52 abut against the two opposite frame edges 111 respectively; and the end plate 52 extends along a direction perpendicular to the first direction to the surface near the color steel plate 11, and sealant is provided at the ends of the two color steel plates 11 near the surface to form an adhesive layer 6; preferably, the thickness of the adhesive layer 6 along the first direction is the same as the thickness of the end plate 52.
[0046] Please see Figure 1 In some possible embodiments, the edge trimming assembly 2 includes a connecting steel plate 21; the connecting steel plate 21 extends along a first direction and abuts against the bottom of a plurality of color steel plates 11 corresponding to the side plate 1; wherein, the lower ends of a plurality of connecting screw rods 3 pass through the connecting steel plate 21 and are fixed by mounting nuts.
[0047] Multiple mounting holes are spaced apart on the connecting steel plate 21 along the first direction. Each mounting hole corresponds to a multiple connecting threaded rod 3. Each connecting threaded rod 3 passes through the corresponding mounting hole and is fixed by screwing on the mounting nut.
[0048] Please see Figure 1 In some embodiments, the bottom of the connecting steel plate 21 is provided with a trimming plate 22 extending in a first direction; the two ends of the trimming plate 22 are bent upward to form an upward-opening U-shaped structure, and abut against and fix to the two side plates 1 of the side plate 1.
[0049] By setting a U-shaped edge plate 22, the lower protruding part of the connecting screw rod 3 and the connecting steel plate 21 can be surrounded in the U-shaped groove of the edge plate 22, so as to improve the aesthetic effect of the smoke curtain and enhance the bottom connection strength and support strength of the smoke curtain.
[0050] Please see Figure 1 In some embodiments, in the horizontal direction perpendicular to the first direction, the two ends of the connecting steel plate 21 are respectively provided with downwardly bent folded edge structures, and the lower end of the folded edge structure abuts against the bottom of the U-shaped groove of the edge-receiving plate 22.
[0051] By setting a folded edge structure and having the lower end of the folded edge structure abut against the bottom of the U-shaped groove of the edge-receiving plate 22, the edge-receiving plate 22 is pressed upward against the connecting plate, thereby pressing the bottom of multiple color steel plates 11 upward, thus ensuring the suspension stability and reliability of multiple color steel plates 11.
[0052] Please see Figure 1For example, the folded edge structure includes a first folded edge, a second folded edge, and a third folded edge connected in sequence; the first folded edge extends downward from the end of the connecting steel plate 21; the second folded edge extends horizontally to the lower end of the first folded edge; and the third folded edge is vertically fixed upward to the extension end of the second folded edge.
[0053] Specifically, the second folded edge is used to abut against the bottom of the U-shaped groove of the edge-receiving plate 22, and the first and third folded edges are used to increase the support strength of the second folded edge, thus achieving the function of a reinforcing rib. Preferably, the two third folded edges of the two sets of folded edge structures are parallel and spaced apart in the middle of the two sets of first folded edges, and the two third folded edges are located on both radial sides of the connecting screw 3, without interfering with the connecting screw 3.
[0054] In some possible embodiments, two sets of side panels 1 are arranged in parallel in a horizontal direction perpendicular to the first direction, and a set of edge trimming components 2 are provided at the bottom of each set of side panels 1; a bottom plate is provided at the bottom of the two sets of side panels 1, and the bottom plate extends along the first direction; the two ends of the bottom plate are respectively connected to the two sets of edge trimming components 2, so that the bottom plate and the two side panels 1 form a box-shaped structure.
[0055] By arranging two side plates 1 in parallel and forming a box-shaped structure with the bottom plate and the two side plates 1, the smoke-blocking area in the horizontal direction perpendicular to the first direction is increased, thereby improving the smoke-blocking effect. Specifically, the specific structure of the baffle can be set according to actual needs. Optionally, the bottom plate and the two side plates 1 can be fixedly connected by rivets. Furthermore, sealant is applied at the joint to ensure connection strength and sealing.
[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
