Abstract
Description
Technical Field
[0001] This utility model relates to the field of smoke curtain technology, and more specifically, to a high-strength rigid smoke curtain. Background Technology
[0002] Smoke curtains are made of non-combustible materials and are vertically installed under the ceiling, beams or suspended ceiling of a building. They are smoke-blocking and separating facilities that can form a certain smoke storage space during a fire. They are usually made of non-combustible rigid materials such as fireproof boards, fireproof glass, and steel plates. The overall structure is relatively sturdy. The main function is to prevent the smoke generated by a fire from spreading laterally in the building and to control the smoke within a certain fire compartment to ensure a smoke-free environment for safe evacuation routes and refuge areas.
[0003] In actual use, existing smoke curtains are fixed together by adhesive. However, after a long period of use, the adhesive surfaces may fall off, resulting in poor adhesion between the smoke curtains.
[0004] A search revealed Chinese patent CN221332529U, which discloses a rigid smoke curtain. This structure features a support frame outside the outer shells of the first and second smoke curtains. A transparent protective plate is installed on the inner wall of the frame, and a fixing block is inserted into a fixing slot, allowing the support frame to be installed outside the outer shell of the smoke curtain. The transparent protective plate provides protection; when an external device collides with it, it contacts the protective plate first, preventing cracks or even breakage of the smoke curtain and effectively improving its protective performance. Furthermore, a clamping block is located on the left side of the outer shells of the first and second smoke curtains, and a fixing block is located on the right side. During installation, the fixing block is inserted into the fixing slot, and the rubber block is fixed in the inner groove. This design avoids the use of adhesive bonding between the smoke curtains, as adhesive bonding is prone to detachment after prolonged use. This structure enhances the stability and reliability of the connection between the smoke curtains.
[0005] However, in actual use, the insert rod is inserted into the first and second sockets to reinforce the fixing block and rubber block. However, the insert rod is only inserted from the side for fixation. When subjected to a large external force in the vertical or torsional direction, the insert rod cannot provide sufficient pull-out and torsional resistance, which may lead to the risk of the fixing block coming out of the fixing slot. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-strength rigid smoke curtain to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A high-strength rigid smoke curtain includes a titanium alloy frame, an alloyed tempered glass fixedly installed inside the titanium alloy frame, a fixing frame installed at the top of the titanium alloy frame, and a fixing mechanism installed inside the fixing frame.
[0009] The fixing mechanism includes a fixing frame inserted into the fixing bracket. Multiple fixing cylinders are fixedly installed inside the fixing frame. A fixing column is slidably installed inside the fixing cylinder. A spring is sleeved on the outside of the fixing cylinder and the fixing column. An inclined plate is fixedly installed on one side of the fixing column and the spring. A through groove is opened inside the fixing frame. An adjusting plate is installed inside the through groove. An insert block is installed on one side of the adjusting plate.
[0010] By adopting the above technical solution: during installation, the inclined plate can be snapped into the fixing frame to achieve a firm connection; during disassembly, the adjusting plate can control the retraction of the inclined plate, making operation convenient. At the same time, the alloyed tempered glass combined with the fireproof fiber reinforced board prevents smoke penetration, and the reinforced steel bars further enhance rigidity, preventing the smoke curtain from cracking under thermal stress and smoke pressure, effectively blocking the spread of smoke.
[0011] As a further description of the above technical solution: a fixing groove is provided on the surface of the fixing frame, one end of the insert block passes through the fixing frame and extends into the fixing frame, a fixing strip is fixedly provided on one side of the fixing frame, the fixing strip and the insert block are both inserted into the fixing groove, one end of the spring is connected to the fixing frame, the other end of the spring and one end of the fixing post are both connected to the inclined plate, threaded holes are provided on the surface of the insert block and the fixing frame, and a first bolt is threaded into the inside of the threaded hole.
[0012] By adopting the above technical solution, the fixed frame is accurately positioned in the fixed bracket, ensuring accurate installation and improving the reliability and safety of the smoke curtain during use.
[0013] As a further description of the above technical solution: a splicing mechanism is provided on one side of the titanium alloy frame. The splicing mechanism includes a connecting frame fixedly disposed on one side of the titanium alloy frame. A connecting groove is opened inside the connecting frame, and a connecting strip is inserted into the connecting groove.
[0014] A limiting groove is formed on the surface of the connecting frame, and an L-shaped limiting plate is inserted into the inside of the limiting groove. The L-shaped limiting plate and the inside of the connecting frame are connected by a second bolt.
[0015] By adopting the above technical solution, multiple titanium alloy frames can be quickly and initially connected by the insertion and cooperation of the connecting groove and the connecting strip in the connecting frame. The operation is simple, and the size and shape of the smoke curtain can be flexibly adjusted according to actual needs to adapt to different scenarios. At the same time, it is convenient for maintenance and repair.
[0016] As a further description of the above technical solution: a mounting plate is fixedly installed on the top of the fixing frame, and multiple threaded mounting holes are opened on the surface of the mounting plate; a fireproof fiber reinforcement plate is fixedly installed on the outside of the alloyed tempered glass; and multiple reinforcing bars are fixedly installed inside the titanium alloy frame.
[0017] By adopting the above technical solution, the fire-resistant fiber reinforcement board on the outside of the alloyed tempered glass can effectively block heat and smoke. Working together with the alloyed tempered glass, it can improve the overall fire resistance, prevent smoke penetration, and ensure that it plays an effective role in a fire.
[0018] The technical effects and advantages of this utility model are as follows:
[0019] By setting up a fixing mechanism, compared with the existing technology, during connection, the fixing frame is inserted into the fixing bracket, the inclined plate is squeezed to deform the spring, the fixed column moves to guide, and after further upward movement, the spring returns to its original position, the inclined plate is locked into the fixing bracket, achieving a firm installation and ensuring the stability of the smoke curtain structure. It can effectively block the spread of smoke in the event of a fire. During disassembly, the first bolt is unscrewed and the insert block is pulled out. The moving adjustment plate squeezes the inclined plate to retract it into the fixing frame, and then the fixing frame is removed. The titanium alloy frame and alloyed tempered glass can be easily disassembled. The operation is simple, which not only ensures the stability after installation, but also facilitates later maintenance and disassembly, improving the convenience and practicality of use. The alloyed tempered glass, fireproof fiber reinforced board and reinforcing steel bars work together to effectively prevent deformation and cracking, and the performance is reliable.
[0020] By setting up a splicing mechanism, compared with existing technologies, during splicing, the titanium alloy frame can be firmly spliced by corresponding insertion of the connecting frame and connecting strip, and fixing strip and fixing groove, in conjunction with the L-shaped limiting plate and the second bolt tightening. This enables the splicing of multiple alloyed tempered glass panels, with orderly and stable operation. Moreover, the insertion of the insert block into the fixing groove achieves the initial positioning of the fixing frame, and the first bolt passes through the threaded hole of the insert block and fixing frame for tightening, further enhancing the connection stability. At the same time, the fixing adjustment plate prevents its movement, ensuring both the integrity and stability of the spliced multiple alloyed tempered glass panels, while also facilitating operation. This is suitable for actual installation needs and provides a reliable foundation for the realization of functions such as smoke curtains. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] The embodiments disclosed in this application are as follows: Figure 1-6 The high-strength rigid smoke curtain shown includes a titanium alloy frame 1, an alloyed tempered glass 2 fixedly installed inside the titanium alloy frame 1, a fixing frame 3 installed on the top of the titanium alloy frame 1, and a fixing mechanism installed inside the fixing frame 3.
[0030] The fixing mechanism includes a fixing frame 4 inserted into the fixing frame 3. Multiple fixing cylinders 5 are fixedly installed inside the fixing frame 4. Fixing columns 6 are slidably installed inside the fixing cylinders 5. Springs 7 are sleeved on the outside of the fixing cylinders 5 and fixing columns 6. An inclined plate 8 is fixedly installed on one side of the fixing columns 6 and springs 7. A through groove is opened inside the fixing frame 4. An adjusting plate 9 is installed inside the through groove. An insert block 10 is installed on one side of the adjusting plate 9.
[0031] The titanium alloy frame 1 with alloyed tempered glass 2 is connected to the fixing frame 3 through a fixing mechanism. First, the fixing frame 4 is inserted into the fixing frame 3. At this time, the inclined plate 8 inside the fixing frame 4 is squeezed by the fixing frame 3 and then moves into the fixing frame 4, thereby squeezing the spring 7 to deform. At the same time, it drives the fixing column 6 to move into the fixing cylinder 5, which plays a guiding role.
[0032] Next, the titanium alloy frame 1 continues to move upward, causing the fixed frame 4 to continue moving upward, thereby bringing the inclined plate 8 into the through groove inside the fixed frame 3. At this time, the spring 7 returns to its original position, thereby causing the fixed column 6 to move outward inside the fixed cylinder 5, which in turn causes the inclined plate 8 to be pushed outward, thus locking the inclined plate 8 into the interior of the fixed frame 3, thereby making the titanium alloy frame 1 securely installed.
[0033] Reference Figure 2-3 As shown, a fixing groove is provided on the surface of the fixing frame 4, one end of the insert 10 passes through the fixing frame 3 and extends into the fixing frame 3, a fixing strip 11 is fixedly provided on one side of the fixing frame 4, the fixing strip 11 and the insert 10 are both inserted into the fixing groove, one end of the spring 7 is connected to the fixing frame 4, the other end of the spring 7 and one end of the fixing post 6 are both connected to the inclined plate 8, the surface of the insert 10 and the fixing frame 4 are both provided with threaded holes, and the first bolt 12 is threadedly connected inside the threaded holes;
[0034] First, unscrew the first bolt 12, pull the insert 10 out of the fixing slot of the fixing frame 4, and then move the adjusting plate 9 to the side closer to the inclined plate 8, so that the adjusting plate 9 can move in the through slot inside the fixing frame 4.
[0035] This compresses the inclined plate 8, causing the spring 7 on one side of the inclined plate 8 to deform, thereby moving the inclined plate 8 into the fixed frame 4 until the inclined plate 8 is completely inside the fixed frame 4. Then the fixed frame 4 can be removed, and the titanium alloy frame 1 and the alloyed tempered glass 2 can be removed from the fixed bracket 3, making disassembly convenient.
[0036] Reference Figure 4-6 As shown, a splicing mechanism is provided on one side of the titanium alloy frame 1. The splicing mechanism includes a connecting frame 13 fixedly installed on one side of the titanium alloy frame 1. A connecting groove is provided inside the connecting frame 13, and a connecting strip 14 is inserted into the connecting groove.
[0037] A limiting groove 15 is provided on the surface of the connecting frame 13, and an L-shaped limiting plate 16 is inserted into the limiting groove 15. The L-shaped limiting plate 16 and the connecting frame 13 are connected by a second bolt 17 through a thread.
[0038] The connecting frame 13 of one titanium alloy frame 1 is aligned with the connecting strip 14 of another titanium alloy frame 1. Then the connecting strip 14 is inserted into the connecting groove inside the connecting frame 13. At the same time, the fixing strip 11 of one titanium alloy frame 1 is inserted into the fixing groove opened on the surface of the fixing frame 4 of another titanium alloy frame 1.
[0039] Next, insert the L-shaped limiting plate 16 into the limiting groove 15 on the surface of the connecting frame 13, and then use the second bolt 17 to insert into the L-shaped limiting plate 16 and the connecting frame 13 and tighten it, so as to firmly splice the two titanium alloy frames 1 together, and then complete the splicing of the two alloyed tempered glass 2. Follow the above steps to splice multiple alloyed tempered glass 2.
[0040] After all the splicing is completed, insert the insert 10 into the fixing slot. Since one end of the insert 10 passes through the fixing frame 3 and extends into the fixing frame 3, inserting it into the fixing slot achieves the initial positioning of the fixing frame 4 in the fixing frame 3.
[0041] The first bolt 12 is passed through the threaded hole on the surface of the insert 10 and the fixing frame 4 and tightened to further fix the insert 10 and the fixing frame 4, ensuring the stability of the connection and fixing it to one side of the adjusting plate 9, and also ensuring that the adjusting plate 9 will not move.
[0042] Reference Figure 2 As shown, a mounting plate 18 is fixedly installed on the top of the mounting bracket 3. Multiple threaded mounting holes 19 are opened on the surface of the mounting plate 18. A fireproof fiber reinforced plate 20 is fixedly installed on the outside of the alloyed tempered glass 2. Multiple reinforcing steel bars 21 are fixedly installed inside the titanium alloy frame 1.
[0043] The titanium alloy frame 1, alloyed tempered glass 2, fireproof fiber reinforced board 20, and reinforcing steel bar 21 work together to effectively block the spread of smoke. The high strength and stability of the titanium alloy frame 1 ensure that the overall structure is not easily deformed or damaged under high temperatures in a fire. The fireproof performance of the alloyed tempered glass 2 and the fireproof fiber reinforced board 20 prevents smoke from penetrating. The reinforcing steel bar 21 further enhances rigidity and prevents the smoke curtain from cracking under thermal stress and smoke pressure.
[0044] Working principle of this utility model:
[0045] This utility model is a high-strength rigid smoke curtain. When using this device, according to the actual installation position and design requirements, the mounting plate 18 is fixed to the predetermined installation position on the ceiling through the threaded mounting holes 19 on its surface using expansion screws. Since the top of the mounting plate 18 is fixedly set on the fixing frame 3, the fixing frame 3 is also fixed accordingly.
[0046] Alloyed tempered glass 2 is installed inside the titanium alloy frame 1. At this time, the fireproof fiber reinforcement plate 20 on the outside of the alloyed tempered glass 2 cooperates with the titanium alloy frame 1. Meanwhile, multiple reinforcing steel bars 21 inside the titanium alloy frame 1 play a role in enhancing the overall rigidity.
[0047] The titanium alloy frame 1 with alloyed tempered glass 2 is connected to the fixing frame 3 through a fixing mechanism. First, the fixing frame 4 is inserted into the fixing frame 3. At this time, the inclined plate 8 inside the fixing frame 4 is squeezed by the fixing frame 3 and then moves into the fixing frame 4, thereby squeezing the spring 7 to deform. At the same time, it drives the fixing column 6 to move into the fixing cylinder 5, which plays a guiding role.
[0048] Next, the titanium alloy frame 1 continues to move upward, driving the fixed frame 4 to continue moving upward, thereby bringing the inclined plate 8 into the through groove inside the fixed frame 3. At this time, the spring 7 returns to its original position, thereby driving the fixed column 6 to move outward inside the fixed cylinder 5, which in turn drives the inclined plate 8 to push outward, thereby inserting the inclined plate 8 into the inside of the fixed frame 3, thus making the titanium alloy frame 1 securely installed.
[0049] Then, when multiple alloyed tempered glass 2 need to be spliced together, a splicing mechanism is used to align the connecting frame 13 of one titanium alloy frame 1 with the connecting strip 14 of another titanium alloy frame 1. Then, the connecting strip 14 is inserted into the connecting groove inside the connecting frame 13. At the same time, a fixing strip 11 of one titanium alloy frame 1 is inserted into the fixing groove opened on the surface of the fixing frame 4 of another titanium alloy frame 1.
[0050] Next, insert the L-shaped limiting plate 16 into the limiting groove 15 on the surface of the connecting frame 13, and then use the second bolt 17 to insert into the L-shaped limiting plate 16 and the connecting frame 13 and tighten it, so as to firmly splice the two titanium alloy frames 1 together, and then complete the splicing of the two alloyed tempered glass 2. Follow the above steps to splice multiple alloyed tempered glass 2.
[0051] After all the splicing is completed, insert the insert 10 into the fixing slot. Since one end of the insert 10 passes through the fixing frame 3 and extends into the fixing frame 3, inserting it into the fixing slot achieves the initial positioning of the fixing frame 4 in the fixing frame 3.
[0052] The first bolt 12 is passed through the threaded hole on the surface of the insert 10 and the fixing frame 4 and tightened to further fix the insert 10 and the fixing frame 4, ensuring the stability of the connection, and fixing it to one side of the adjusting plate 9, also ensuring that the adjusting plate 9 will not move.
[0053] When a fire occurs, the smoke curtain, having been securely installed beforehand, effectively blocks the spread of smoke thanks to the combined action of its titanium alloy frame 1, alloyed tempered glass 2, fire-resistant fiber reinforced board 20, and reinforcing steel bars 21. The high strength and stability of the titanium alloy frame 1 ensure that the overall structure is not easily deformed or damaged under the high temperatures of a fire; the fire-resistant properties of the alloyed tempered glass 2 and the fire-resistant fiber reinforced board 20 prevent smoke penetration; and the reinforcing steel bars 21 further enhance rigidity, preventing the smoke curtain from cracking under thermal stress and smoke pressure.
[0054] When disassembly is required, first unscrew the first bolt 12, pull the insert 10 out of the fixing slot of the fixing frame 4, and then move the adjusting plate 9 to the side closer to the inclined plate 8, so that the adjusting plate 9 can move in the through slot inside the fixing frame 4.
[0055] This compresses the inclined plate 8, causing the spring 7 on one side of the inclined plate 8 to deform, thereby moving the inclined plate 8 into the fixed frame 4 until the inclined plate 8 is completely inside the fixed frame 4. Then the fixed frame 4 can be removed, and the titanium alloy frame 1 and the alloyed tempered glass 2 can be removed from the fixed bracket 3, making disassembly convenient.
[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
