Description

Technical Field

[0001] This invention belongs to the field of building fire protection technology, and more specifically, it relates to a deformation-resistant and fireproof roller shutter installation structure. Background Technology

[0002] In modern building design, seismic isolation layers, with their ability to buffer and dissipate seismic energy, have become one of the core structures for improving the seismic safety of buildings; while fireproof roller shutters, as key fire-resistant partitions, can quickly form fire barriers in the event of a fire, effectively curbing the spread of fire and providing critical time guarantees for personnel evacuation and fire response. Both occupy an indispensable position in the building safety system.

[0003] However, in existing buildings, the installation of seismic isolation layers and fire-resistant roller shutters is often independent, failing to form a coordinated and compatible structural system. This makes the dual safety protection function prone to failure under extreme conditions. On the one hand, the traditional fire-resistant roller shutter installation structure does not consider the horizontal displacement characteristics of the seismic isolation layer. Its steel roller shutter panels have high rigidity, which creates lateral constraints when directly rigidly connected to the main building structure. This hinders the seismic isolation bearings from performing normal horizontal sliding seismic isolation, weakening the overall seismic performance of the building. On the other hand, during an earthquake, the relative horizontal displacement of the upper and lower structures of the seismic isolation layer is directly transmitted to the guide rail structure of the fire-resistant roller shutter, causing deformation problems such as twisting and misalignment of the guide rails. This can lead to the roller shutter panels getting stuck, preventing them from opening and closing normally during a fire and causing them to lose their fire-resistant separation function. Summary of the Invention

[0004] The purpose of this invention is to provide a deformation-resistant and fireproof roller shutter installation structure that combines seismic isolation and fireproof functions through structural collaborative design, ensuring stable and reliable operation under extreme conditions such as earthquakes, fires, and the superposition of both.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a deformation-resistant and fireproof roller shutter installation structure, comprising: The main structure includes an upper structure and a lower structure. The lower end face of the upper structure is provided with two downwardly extending upper supports, and the upper end face of the lower structure is provided with two upwardly extending lower supports. The two upper supports and the two lower supports are arranged opposite to each other, and a seismic isolation bearing is provided between the upper supports and the lower supports. The roller blind mechanism includes a roller blind box horizontally installed on the upper structure. The roller blind box is located between two upper supports and contains a retracted roller blind panel inside. Fixed columns are longitudinally arranged at both ends of the roller blind box. The upper part of the fixed column is fixedly connected to the upper support on the same side, and the lower part of the fixed column is in a cantilever state, forming a reserved gap with the lower support on the same side. Roller blind guide rails are longitudinally arranged on the opposite sidewalls of the two fixed columns. The upper ends of the two roller blind guide rails extend to the roller blind box to guide the roller blind panel to move downward to unfold or move upward to retract. Two horizontal sliding mechanisms are respectively installed at the bottom of the two fixed columns. The horizontal sliding mechanism includes a slider fixed to the lower end face of the fixed column and an embedded part installed in the lower structure. The slider is slidably installed on the upper end face of the embedded part, and the circumferential direction of the slider forms a clearance gap to avoid the horizontal displacement of the lower end of the fixed column.

[0006] In one possible implementation, the horizontal sliding mechanism further includes: An adapter groove is provided at the upper end of the lower structure. The bottom of the adapter groove is flush with the finished surface of the lower structure, and the top of the adapter groove is flush with the finished building surface of the lower structure. The embedded part is located at the bottom of the adapter groove, the slider is located in the adapter groove, and it forms the clearance gap with the circumferential edge of the adapter groove.

[0007] In one possible implementation, the upper end of the adapter groove is sealed with a sliding cover plate, and the sliding cover plate slides in contact with the finished building surface of the lower structure. The middle part of the sliding cover plate is sleeved on the outer periphery of the fixed column, and the sliding cover plate is always in the state of sealing the adapter groove as the fixed column moves horizontally.

[0008] In one possible implementation, the upper end of the adapter slot has a buffer slot, the buffer slot is connected to the adapter slot, and the outer diameter of the buffer slot is larger than the outer diameter of the adapter slot. A sealing cover plate is provided inside the buffer groove. A connecting plate for connecting the slider is provided on the lower end face of the sealing cover plate. The middle part of the sealing cover plate is sleeved on the outer periphery of the fixed column. A sealing part is filled inside the buffer groove and surrounds the outer periphery of the sealing cover plate.

[0009] In one possible implementation, the sealing cover is two brittle fireproof plates that are split open, and the two brittle fireproof plates are fastened to each other on the outer periphery of the fixing post. The sealing part is a fireproof sealant filled between the circumferential edges of the two brittle fireproof plates and the circumferential edge of the buffer groove.

[0010] In one possible implementation, the sealing cover is a rigid plate integrally formed, the middle part of the rigid plate is welded and fixed to the fixing post, and the sealing part is a flexible filling material filled between the circumferential edge of the rigid plate and the circumferential edge of the buffer groove.

[0011] In one possible implementation, the embedded part is a horizontally arranged stainless steel plate with a sliding material coated on its upper surface.

[0012] In one possible implementation, the fixed column and the roller shutter guide rail are surrounded by fireproof material, and the outer periphery of the fireproof material is sealed with fireproof board.

[0013] In one possible implementation, a first fixed track and a second fixed track are spaced apart within the reserved gap. Both the first fixed track and the second fixed track extend longitudinally. The upper ends of the first fixed track and the second fixed track are connected to the upper part of the fixed column. A flexible fireproof cloth is provided between the first fixed track and the second fixed track.

[0014] In one possible implementation, the first fixed track includes an upper track, a sealant caulking structure, and a lower track arranged sequentially from top to bottom. The upper end of the upper track is connected to the upper part of the fixed column, and the lower track is fixedly connected to the lower support. The upper end of the lower track is flush with the upper surface of the lower support.

[0015] The beneficial effects of the anti-deformation and fireproof roller shutter installation structure provided by this invention are as follows: Compared with the prior art, the main structure provides basic seismic isolation capability for the overall structure through the corresponding arrangement of upper supports, lower supports, and seismic isolation bearings, which can effectively weaken the transmission of seismic energy and reduce the vibration response of the main structure. In the roller shutter mechanism, the roller shutter box is located between the two upper supports. The design of rigid connection between the upper part of the fixed column and the upper support and the reserved gap at the bottom not only ensures the stability of the roller shutter guide rail installation, but also reserves buffer space for the horizontal displacement of the fixed column driven by the upper support during an earthquake, avoiding the breakage or deformation of the fixed column due to rigid constraints. The horizontal sliding mechanism further adapts to the horizontal displacement requirements of the bottom of the fixed column through the sliding cooperation of the slider and the embedded part. The circumferential clearance can completely avoid collision interference during the displacement process. At the same time, the rigid connection between the slider and the embedded part ensures that the bottom of the fixed column is always in a stable support state, avoiding large swaying of the cantilever end due to seismic load. In fire conditions, the roller shutter panels unfold smoothly along the guide rails to form a reliable fireproof partition. The rigid connection between the fixed columns and the guide rails, along with the stable support of the sliders, effectively resists structural deformation under high fire temperatures, preventing gaps in the roller shutter that could lead to fireproofing failure. When encountering a combination of earthquake and fire conditions, the seismic isolation bearings weaken the impact of the earthquake, the horizontal sliding mechanism adapts to structural displacement, and the reserved gaps and clearance gaps in the fixed columns provide dual displacement compensation. These three elements work together to ensure that the roller shutter mechanism does not suffer structural damage during earthquake vibrations, while the roller shutter panels can unfold normally and maintain fireproof integrity, achieving stable and reliable operation under extreme conditions.

[0022] Please see Figures 1 to 13 The present invention will now describe a deformation-resistant and fireproof roller shutter installation structure. The deformation-resistant and fireproof roller shutter installation structure includes a main structure, a roller shutter mechanism, and two horizontal sliding mechanisms.

[0023] The main structure includes an upper structure 1 and a lower structure 3. The lower end of the upper structure 1 has two downward-extending upper supports 2, and the upper end of the lower structure 3 has two upward-extending lower supports 4. The two upper supports 2 and the two lower supports 4 are arranged opposite each other, and a seismic isolation bearing 5 is provided between the upper supports 2 and the lower supports 4. The roller shutter mechanism includes a roller shutter box 6 horizontally installed on the upper structure 1. The roller shutter box 6 is located between the two upper supports 2 and contains a retracted roller shutter panel. Fixed columns 7 are longitudinally installed at both ends of the roller shutter box 6. The upper part of the fixed columns 7 is fixedly connected to the upper supports 2 on the same side. The lower part of column 7 is in a cantilever state and forms a reserved gap with the lower support 4 on the same side. The opposite side walls of the two fixed columns 7 are respectively provided with roller shutter guide rails 8 longitudinally. The upper ends of the two roller shutter guide rails 8 extend to the roller shutter box 6 to guide the roller shutter panel to move downward to unfold or move upward to retract. Two horizontal sliding mechanisms are respectively set at the bottom of the two fixed columns 7. The horizontal sliding mechanism includes a slider 9 fixed to the lower end face of the fixed column 7 and a pre-embedded part 10 set in the lower structure 3. The slider 9 is slidably set on the upper end face of the pre-embedded part 10. The circumference of the slider 9 forms a clearance gap to avoid the horizontal displacement of the lower end of the fixed column 7.

[0024] This invention provides a deformation-resistant and fireproof roller shutter installation structure. Compared with existing technologies, the main structure provides basic seismic isolation capability for the overall structure through the corresponding arrangement of upper supports 2, lower supports 4, and seismic isolation bearings 5, which can effectively weaken the transmission of seismic energy and reduce the vibration response of the main structure. In the roller shutter mechanism, the roller shutter box 6 is located between the two upper supports 2. The design of the upper part of the fixed column 7 being rigidly connected to the upper supports 2 and the lower part having a reserved gap ensures the stability of the roller shutter guide rail 8 installation and also provides a buffer space for the horizontal displacement of the fixed column 7 driven by the upper supports 2 during an earthquake, avoiding the fixed column 7 from breaking or deforming due to rigid constraints. The horizontal sliding mechanism further adapts to the horizontal displacement requirements of the bottom of the fixed column 7 through the sliding cooperation of the slider 9 and the embedded part 10. The circumferential clearance can completely avoid collision interference during the displacement process. At the same time, the rigid connection between the slider 9 and the embedded part 10 ensures that the bottom of the fixed column 7 is always in a stable support state, avoiding large swaying of the cantilever end due to seismic loads. In fire conditions, the roller shutter panel unfolds smoothly along the guide rail to form a reliable fireproof partition. The rigid connection between the fixed column 7 and the guide rail, along with the stable support of the slider 9, effectively resists structural deformation under high fire temperatures, preventing gaps in the roller shutter that could lead to fireproof failure. When encountering a combination of earthquake and fire conditions, the seismic isolation support 5 weakens the impact of the earthquake, the horizontal sliding mechanism adapts to structural displacement, and the reserved gap and clearance gap of the fixed column 7 provide dual displacement compensation. These three elements work together to ensure that the roller shutter mechanism does not suffer structural damage during earthquake vibrations, while the roller shutter panel can unfold normally and maintain fireproof integrity, achieving stable and reliable operation under extreme conditions.

[0025] Please see Figure 1 , Figure 6 , Figure 7 as well as Figure 12 The horizontal sliding mechanism also includes an adapter groove 12. The adapter groove 12 is the load-bearing structure and limiting component of the horizontal sliding mechanism. It is integrally opened on the upper end surface of the lower structure 3, and adopts a structure in which the bottom of the groove is flush with the finished surface 13 of the structure and the top of the groove is flush with the finished surface 14 of the building, forming an embedded installation space that is seamlessly connected with the lower structure 3.

[0026] The embedded part 10 serves as a sliding foundation and is fixed at the bottom of the adapter groove 12, forming a rigid connection with the lower structure 3. The slider 9 fits against the upper surface of the embedded part 10 and is embedded in the adapter groove 12. An annular clearance is reserved between the outer peripheral wall of the slider 9 and the inner side wall of the adapter groove 12, which not only ensures the horizontal sliding freedom of the slider 9 along the embedded part 10, but also achieves vertical limitation and lateral protection of the slider 9 through the adapter groove 12.

[0027] The aforementioned adapter groove 12 provides fitting space for the slider 9. Its circumferential clearance avoids horizontal displacement of the slider 9 caused by the fixed column 7 during an earthquake, preventing direct collision between the slider 9 and the lower structure 3. Simultaneously, the groove wall of the adapter groove 12 prevents external debris from entering the sliding surface, preventing the slider 9 from jamming and ensuring smooth operation of the horizontal sliding mechanism. Furthermore, the design of the bottom of the adapter groove 12 being flush with the finished surface 13 of the structure ensures a tight fit between the embedded part 10 and the structural layer of the lower structure 3 during installation, improving connection stability. The top of the adapter groove 12 being flush with the finished building surface 14 achieves a seamless connection between the structure and the building surface, without affecting ground access or aesthetic decoration, adapting to the installation needs of various building scenarios. The vertical limiting effect of the adapter groove 12 on the slider 9 allows the vertical load of the fixed column 7 to be evenly transferred to the lower structure 3 through the slider 9 and the embedded part 10, preventing the fixed column 7 from tilting due to vertical instability of the sliding mechanism and ensuring the installation accuracy of the roller shutter mechanism.

[0028] Meanwhile, in the event of a fire, the adapter groove 12 can form a closed heat insulation cavity, and the groove wall can slow down the transmission speed of high temperature to the embedded part 10 and the slider 9; at the same time, the slider 9 is embedded in the groove, which can prevent falling objects from directly impacting the sliding surface in the fire, prevent the failure of the sliding mechanism from causing the roller shutter guide rail 8 to deform, and indirectly improve the fireproof integrity of the fireproof roller shutter.

[0029] Please see Figure 12 Based on the original adapter groove 12 structure, a sliding cover plate 15 is added as the upper end sealing component of the adapter groove 12, forming a composite protective structure of embedded groove and sliding sealing.

[0030] The lower end face of the sliding cover plate 15 forms a surface contact sliding fit with the top edge of the adapter groove 12, ensuring that the cover plate can move freely horizontally along the groove and fit tightly. A circular, square, or irregularly shaped through hole adapted to the outer circumference of the fixed column 7 is opened in the middle of the sliding cover plate 15. The inner wall of the through hole is covered with wear-resistant material or directly welded and fixed. After being fitted onto the lower outer circumference of the fixed column 7, the through hole and the fixed column 7 are matched to achieve a follow-up connection. When the fixed column 7 is horizontally displaced due to earthquakes or other conditions, the fixed column 7 can drive the sliding cover plate 15 to slide synchronously along the groove of the adapter groove 12 through the inner wall of the through hole. During the entire displacement process, the coverage area of ​​the sliding cover plate 15 always completely overlaps with the groove of the adapter groove 12, maintaining a continuous sealing state of the adapter groove 12. At the same time, the upper end face of the sliding cover plate 15 is flush with the finished building surface 14 of the lower structure 3, forming a ground connection without height difference.

[0031] The sliding cover 15 provides complete enclosure protection for the adapter groove 12, completely blocking the entry of dust, sand, construction debris, and other impurities into the adapter groove 12. This avoids problems such as wear and jamming of the sliding surface between the slider 9 and the embedded part 10 due to debris accumulation, significantly improving the service life and operational reliability of the horizontal sliding mechanism. Simultaneously, the sliding cover 15 effectively prevents liquids (such as cleaning water and fire-fighting water) from seeping into the adapter groove 12, preventing corrosion of the embedded part 10 and the slider 9, ensuring smooth horizontal sliding during earthquakes, and providing stable protection for the displacement compensation of the fixed column 7. The design of the sliding cover 15 being flush with the finished building surface 14 and sliding synchronously solves the problems of insufficient ground flatness and tripping hazards caused by the exposed groove opening of the traditional adapter groove 12, meeting the daily needs of personnel passage and equipment handling, and is especially suitable for densely populated or high-frequency operation locations such as shopping malls, hospitals, and factories.

[0032] In addition, when an earthquake occurs, the sliding cover plate 15 moves horizontally in sync with the fixed column 7, always keeping the adapter groove 12 sealed, thus preventing building debris generated by the earthquake from entering the groove. Subsequently, when a fire occurs, even if the fixed column 7 shifts due to the earthquake, the cover plate can still tightly cover the groove opening, preventing flames and smoke from spreading through the adapter groove 12, thus ensuring the synergistic effect of seismic isolation and fire prevention.

[0033] In the event of accidental impacts such as equipment collisions or personnel falls during daily use, the sliding cover 15 can serve as a buffer and protective component at the lower part of the fixed column 7. The impact load is first applied to the sliding cover 15, which distributes the load to the wall of the adapter groove 12 through its sliding engagement with the groove opening, preventing the impact load from directly acting on the fixed column 7 and causing it to deform or break. At the same time, the rigid structure of the sliding cover 15 can effectively protect the sliding mechanism inside the adapter groove 12 from impact damage, thus forming the above-mentioned double protection and improving the safety of the structure in daily use.

[0034] Please see Figure 6 and Figure 12 Based on the original adapter groove 12, an optimization is made to form a multi-layered composite structure consisting of adapter groove 12, buffer groove, sealing cover plate 17, and sealing part 19, which works in conjunction with the overall fireproof roller shutter installation system. Among them, the buffer groove is opened at the upper end of the adapter groove 12 and is coaxially connected to the adapter groove 12. Its inner diameter is larger than that of the adapter groove 12, forming a stepped groove structure that is wider at the top and narrower at the bottom. The bottom of the groove is connected to the top of the adapter groove 12, and the top of the groove is flush with the finished surface 14 of the lower structure 3, ensuring a smooth structural transition.

[0035] The sealing cover plate 17 is a circular plate-shaped component adapted to the buffer groove, horizontally set inside the buffer groove. Its outer diameter is smaller than the inner diameter of the buffer groove. A vertically extending connecting plate 18 is fixedly connected to the center of its lower end face. The lower end of the connecting plate 18 is rigidly connected to the top surface of the slider 9 of the horizontal sliding mechanism, forming an integrated linkage structure of the cover plate, the connecting plate 18, and the slider 9. A through hole adapted to the outer circumference of the fixed post 7 is opened in the middle of the sealing cover plate 17. The inner wall of the through hole is covered with wear-resistant material or directly welded and fixed. After being fitted onto the lower outer circumference of the fixed post 7, the sealing cover plate 17 achieves follow-up constraint through the fit between the through hole and the fixed post 7. The space between the inner wall of the buffer tank and the outer peripheral wall of the sealing cover plate 17 is filled with a sealing part 19, which is made of a high-temperature resistant, highly elastic fireproof sealant. It tightly surrounds the outer periphery of the sealing cover plate 17, and after filling, the upper end face of the sealing part 19 is flush with the top of the buffer tank, forming a tight seal with the sealing cover plate 17 and the inner wall of the buffer tank. The sealing part 19 uses a high-temperature resistant fireproof material 21, which can form an expanding sealing layer upon contact with fire, filling the gaps caused by the displacement of the sealing cover plate 17 and preventing the spread of high-temperature smoke and flames through the tank. Furthermore, the heat insulation properties of the sealing part 19 reduce the outward diffusion of heat from inside the tank, preventing thermal damage to surrounding structures.

[0036] Please see Figure 5 The sealing cover 17 consists of two symmetrically shaped brittle fireproof boards, split open. The boards are made of brittle fireproof materials 21, such as calcium silicate board or fiber-reinforced cement board, which can maintain structural integrity at high temperatures. A semi-circular notch is cut on one edge of each fireproof board. When the two boards are interlocked, the notches combine to form a circular through hole that matches the outer circumference of the fixing post 7, allowing for a tight fit to the lower part of the fixing post 7. A gap of 1-2mm is left between the interlocking surfaces of the two brittle fireproof boards to avoid installation interference and provide a slight buffer for subsequent displacement.

[0037] The sealing part 19 uses a fireproof sealant with excellent elasticity, which is evenly filled between the circumferential edges of the two brittle fireproof boards and the circumferential inner wall of the buffer groove. After filling, the upper surface of the sealant is flush with the top of the buffer groove and the top surface of the fireproof board, forming a closed surface that is seamlessly connected to the ground. At the same time, the sealant forms a tight bond with the fireproof board and the inner wall of the buffer groove to ensure the initial sealing performance.

[0038] If a high-intensity earthquake causes displacement exceeding the elastic limit of the sealant, the brittle fireproof board will undergo controlled fracture along pre-set micro-gaps or weak points. This releases displacement stress, preventing damage to the fixing column 7, and provides basic support for the fixing column 7 by maintaining connection between the fractured board fragments and the slider 9. Subsequently, in the event of a fire, the fireproof sealant at the fracture point expands upon contact with fire, filling the gaps in the board fracture. At the same time, the fragments can still serve as a supporting framework for the sealing layer, ensuring that the sealing and fireproof functions remain intact. This solves the problem of sealing failure caused by excessive displacement in traditional structures.

[0039] Please see Figure 11 The sealing cover 17 is a rigid plate formed in one piece. The middle part of the rigid plate is welded and fixed to the fixing post 7. The sealing part 19 is a flexible filler material that fills the space between the circumferential edge of the rigid plate and the circumferential edge of the buffer groove. The sealing cover 17 is made of high-strength metal materials such as Q235 steel or stainless steel into a rigid plate formed in one piece. The thickness of the plate is set according to the diameter of the fixing post 7 and the stress requirements to ensure sufficient structural rigidity. A circular through hole matching the outer circumferential size of the fixing post 7 is opened in the middle of the rigid plate. During installation, the lower part of the fixing post 7 passes through the through hole, and the two are connected by a full welding process. The weld height is not less than the thickness of the plate, forming a rigid integrated structure of the fixing post 7 and the rigid plate.

[0040] The outer diameter of the rigid plate is smaller than the inner diameter of the buffer groove. After installation, its lower end face is tightly fitted with the top surface of the slider 9 of the horizontal sliding mechanism (not a rigid connection, only forming surface support). A 10-15mm annular gap is reserved between the circumferential edge and the inner wall of the buffer groove. The sealing part 19 uses a high-temperature resistant and highly elastic flexible filling material (such as ceramic fiber rope wrapped with fireproof silicone strip or elastic fireproof sealant), which is tightly filled in the annular gap between the circumferential edge of the rigid plate and the inner wall of the buffer groove. After filling, the upper end face of the flexible material is flush with the top surface of the rigid plate and the top of the buffer groove, forming a closed surface that is seamlessly connected to the ground. At the same time, the flexible material itself forms a tight seal with the rigid plate and the inner wall of the buffer groove through its elastic deformation.

[0041] The integrally molded rigid plate is welded and fixed to the fixing column 7, forming a rigid whole with no relative displacement. The lower end face of the rigid plate cooperates with the surface support of the slider 9, which is equivalent to adding a rigid support point to the lower cantilever section of the fixing column 7. This can effectively resist the lateral bending moment of the fixing column 7 due to its own weight, wind force or vibration during the raising and lowering of the roller shutter, and greatly reduce the lateral sway of the fixing column 7. This support is directly transmitted to the roller shutter guide rail 8, ensuring that the guide rail always maintains verticality and avoiding problems such as jamming, offset or excessive sealing gaps when the roller shutter is raised and lowered.

[0042] As the main sealing element, the rigid plate, with its high strength, effectively blocks the impact of heavy objects, trampling by personnel, and crushing by large equipment, preventing damage to core components such as the slider 9 and embedded parts 10 inside the tank. Simultaneously, the rigid plate's sealing properties completely prevent dust, sand, liquids, and other debris from entering the adapter groove 12, preventing wear and corrosion of the sliding surface and extending the service life of the sliding mechanism. The high elasticity of the flexible filling material allows it to adapt to the horizontal displacement of the rigid plate with the fixed column 7. Within the range of normal seismic displacement (≤60mm), the material only undergoes elastic deformation without breakage, always filling the gap between the rigid plate and the buffer groove, maintaining the continuity of the sealing protection.

[0043] Please see Figure 6 and Figure 12The embedded part 10 is a horizontally positioned stainless steel plate with a sliding material 20 coated on its upper surface. The embedded part 10 is made of 304 or 316L stainless steel and is rigidly connected to the lower structure 3 via reinforcing bars to ensure load-bearing stability. After polishing, the upper surface of the stainless steel plate is uniformly coated with a 2-3mm thick layer of special sliding material 20 (such as a polytetrafluoroethylene coating or a modified epoxy resin sliding coating). The surface flatness error of the coating is controlled within 0.5mm / m, forming a low-friction sliding surface. The slider 9 of the horizontal sliding mechanism is made of wear-resistant alloy steel, with its lower end face tightly fitted to the sliding coating to form a sliding pair; the upper end face of the slider 9 is tightly fitted to the lower end face of the integrally formed rigid sealing plate.

[0044] Please see Figure 3 , Figure 4 , Figure 9 as well as Figure 10 The fixed column 7 and the roller shutter guide rail 8 are wrapped with fireproof material 21, and fireproof board 22 is sealed around the outer periphery of the fireproof material 21. The fixed column 7 is wrapped with fireproof and heat-insulating material (such as alkali-free glass wool felt or intumescent fireproof coating) from below the connection between the upper part and the upper support 2 to above the connection between the lower slider 9 and the fixed column 7. When wrapping, a gap is reserved between the fixed column 7 and the roller shutter guide rail 8. After the roller shutter guide rail 8 is fixed to the opposite side wall of the fixed column 7, its exposed side wall and upper and lower ends are wrapped with fireproof material 21 of the same specification to ensure that there is no blind spot in the connection node between the guide rail and the fixed column 7.

[0045] Fireproof boards 22 (such as fiber-reinforced cement fireproof boards or calcium silicate fireproof boards) are used for sealing and installation around the fireproof insulation material. The fireproof boards 22 are connected and fixed to the fixing columns 7 by fireproof bolts. The joints of the boards are filled with fireproof sealant. The upper and lower ends of the fireproof boards 22 are seamlessly connected to the bottom of the roller shutter box 6 and the top surface of the rigid sealing plate, respectively, to achieve full-height fire protection from the roller shutter box 6 to the sliding mechanism.

[0046] Please see Figure 7 and Figure 12Within the reserved gap, a first fixed rail and a second fixed rail 26 are spaced apart. Both the first and second fixed rails 26 extend longitudinally, and their upper ends are connected to the upper part of the fixed column 7. A flexible fireproof cloth 27 is placed between the first and second fixed rails 26. The first and second fixed rails 26 are arranged side-by-side within the reserved gap. Both rails are made of 10mm thick stainless steel plate, bent into a "U" shape, with their openings facing each other. The upper end of the first fixed rail is rigidly connected to the upper part of the fixed column 7 by fireproof bolts or welding. The upper end of the second fixed rail 26 is at the same height as the first fixed rail and fixed in the same way. Both rails extend longitudinally downwards to a distance from the top surface of the rigid sealing plate without contact. Specifically, the lower ends of the rails are in a free state and maintain a safe distance of 20-30mm from the lower support 4.

[0047] Between the relative openings of the first and second fixed tracks 26, a 1.2mm thick silicone rubber-coated fiberglass cloth (flexible fireproof cloth 27) is used for sealing and connection. The left and right sides of the fireproof cloth are respectively embedded in the "U"-shaped openings of the two tracks and fixed by fireproof strips and bolts. At the same time, the connection nodes between the tracks and the fixed columns 7, and the fixing nodes between the fireproof cloth and the tracks are all covered by the fireproof insulation material and fireproof board 22 of the column fireproof wrapping system, forming blind-spot-free protection.

[0048] Please see Figure 13 The first fixed track adopts a segmented design, consisting of three parts from top to bottom: an upper track 23, a sealant caulking structure 24, and a lower track 25. All three are coaxially arranged and are longitudinally extending "U"-shaped stainless steel tracks, with their openings opposite the second fixed track 26. The upper end of the upper track 23 is rigidly connected to the upper part of the fixed column 7 via fireproof bolts, and the lower end extends to the middle of the reserved gap. The lower track 25 is rigidly fixed to the lower support 4 using a rebar anchoring method, with its upper end flush with the upper surface of the lower support 4, and is entirely fixed to the side wall of the lower support 4. The sealant caulking structure 24 consists of high-temperature resistant elastic fireproof sealant and metal fittings, filling the stepped fitting gap between the upper track 23 and the lower track 25 to form a sealed and slightly deformable connection node. The second fixed track 26 is also an integral "U"-shaped stainless steel track, with its upper end rigidly connected to the upper part of the fixed column 7 and its lower end extending 20mm from the upper surface of the lower support 4. Between the relative openings of the first fixed track (upper + lower) and the second fixed track 26, a flexible fireproof cloth 27 with a thickness of 1.2mm is laid. The left and right sides of the fireproof cloth are respectively embedded into the openings of the two tracks and fixed by fireproof strips. The upper and lower ends are respectively sealed and fitted to the track mounting base of the fixed column 7 and the upper end face of the lower support 4. The joints are filled with fireproof sealant and the whole is covered by the column fireproof wrapping system.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
