Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building fire prevention, and more particularly relates to a deformation-preventing fire-resistant curtain arrangement structure. BACKGROUND

[0002] In modern building design, the seismic isolation layer becomes one of the core structures for improving the seismic safety of buildings due to its buffering and resolving effect on seismic energy, and the fire-resistant curtain, as a key fireproof separation facility, can quickly form a fireproof barrier when a fire occurs, effectively curb the spread of fire, and provide key time guarantee for personnel evacuation and fire disposal. Both of them occupy an indispensable position in the building safety system.

[0003] However, the arrangement of the seismic isolation layer and the fire-resistant curtain in the existing building is in an independent state, and a coordinated and adaptive structural system has not been formed, which leads to the risk of failure of double safety guarantee functions under extreme working conditions: on the one hand, the arrangement structure of the traditional fire-resistant curtain does not consider the horizontal displacement characteristics of the seismic isolation layer, and the steel curtain plate has large rigidity, which will form lateral constraint when directly connected with the building body, hinder the normal horizontal sliding isolation effect of the seismic isolation bearing, and weaken the overall seismic performance of the building; on the other hand, when an earthquake occurs, the relative horizontal displacement of the upper and lower structures of the seismic isolation layer will be directly transmitted to the guide rail structure of the fire-resistant curtain, causing deformation problems such as twisting and misalignment of the guide rail, and then causing the curtain plate to be stuck, so that it cannot be normally opened and closed when a fire occurs, and loses the fire separation function.

[0040] Please refer to Figures 1 to 13 A kind of fireproof curtain cloth arrangement structure of anti-deformation is described below.The fireproof curtain cloth arrangement structure of anti-deformation includes structure main body, curtain mechanism and two horizontal sliding mechanisms.

[0041] The structure main body includes upper structure body 1 and lower structure body 3, the lower end surface of the upper structure body 1 is provided with two upper buttresses 2 extending downward, the upper end surface of the lower structure body 3 is provided with two lower buttresses 4 extending upward, the two upper buttresses 2 and the two lower buttresses 4 are arranged opposite to each other, and the upper buttress 2 and the lower buttress 4 are provided with a shock isolation support 5; the curtain mechanism includes a curtain box 6 transversely mounted on the upper structure body 1, the curtain box 6 is located between the two upper buttresses 2, and internally accommodates a curtain plate in a storage state, both ends of the curtain box 6 are respectively provided with a fixed column 7 longitudinally, the fixed column 7 is fixedly connected with the upper buttress 2 on the same side at the upper part, the fixed column 7 is in a cantilever state at the lower part, and forms a reserved gap with the lower buttress 4 on the same side, the opposite side walls of the two fixed columns 7 are respectively provided with a curtain guide rail 8 longitudinally, the upper ends of the two curtain guide rails 8 extend to the curtain box 6, for guiding the curtain plate to move downward to expand or move upward to store; the two horizontal sliding mechanisms are correspondingly arranged at the bottom of the two fixed columns 7, and the horizontal sliding mechanism includes a sliding block 9 fixed to the lower end surface of the fixed column 7 and a pre-embedded part 10 provided on the lower structure body 3, the sliding block 9 is slidingly arranged on the upper end surface of the pre-embedded part 10, and the circumferential direction of the sliding block 9 forms a gap for avoiding the horizontal displacement of the lower end of the fixed column 7.

[0042] The anti-deformation fireproof curtain fabric arrangement structure provided by the application compared with the prior art, the corresponding arrangement of the structure main body through the upper support pier 2, the lower support pier 4 and the shock isolation support 5 provides the basic shock isolation capacity for the overall structure, can effectively weaken the earthquake energy transmission and reduce the main structure vibration response. The curtain box 6 in the curtain mechanism is located between the two upper support piers 2, the upper part of the fixed column 7 is rigidly connected with the upper support pier 2, the lower part is designed with a reserved gap, which not only ensures the stability of the installation of the curtain guide rail 8, but also reserves a buffer space for the horizontal displacement of the upper support pier 2 driving the fixed column 7 during the earthquake, avoiding the fracture or deformation of the fixed column 7 due to rigid constraint. The horizontal sliding mechanism further adapts to the horizontal displacement requirement of the bottom of the fixed column 7 through the sliding cooperation of the sliding block 9 and the embedded part 10, the circumferential displacement gap can completely avoid the collision interference in the displacement process, and the rigid connection of the sliding block 9 and the embedded part 10 ensures that the bottom of the fixed column 7 is always in a stable support state, avoiding the large swing of the cantilever end due to the earthquake load. Under the fire working condition, the curtain plate can form reliable fireproof separation after being stably unfolded along the guide rail, the rigid connection of the fixed column 7 and the guide rail and the stable support of the sliding block 9 can effectively resist the structural deformation under the high temperature of the fire, preventing the fireproof failure caused by the gap of the curtain. When encountering the superimposed working condition of earthquake and fire, the shock isolation support 5 weakens the earthquake influence, the horizontal sliding mechanism adapts to the structural displacement, the reserved gap and the displacement gap of the fixed column 7 form double displacement compensation, and the three cooperate to ensure that the curtain mechanism does not occur structural damage in the earthquake vibration, at the same time, the curtain plate can be normally unfolded and keep the fireproof integrity, realizing the stable and reliable work under the extreme working condition.

[0043] Please refer to Figure 1 、 Figure 6 、 Figure 7 and Figure 12 , the horizontal sliding mechanism further comprises an adaptive slot 12. The adaptive slot 12 is a bearing structure and a limiting member of the horizontal sliding mechanism, and is integrally arranged on the upper end face of the lower structure body 3, and is arranged in a structure that the slot bottom is flush with the structure completion surface 13 and the slot top is flush with the building completion surface 14, forming an embedded installation space seamlessly connected with the lower structure body 3.

[0044] The embedded part 10 is fixed to the slot bottom position of the adaptive slot 12 and is rigidly connected with the lower structure body 3; the sliding block 9 is attached to the upper end face of the embedded part 10 and is integrally embedded in the adaptive slot 12, and an annular displacement gap is reserved between the outer peripheral wall of the sliding block 9 and the inner side wall of the adaptive slot 12, which not only ensures the horizontal sliding freedom of the sliding block 9 along the embedded part 10, but also realizes the vertical limiting and lateral protection of the sliding block 9 through the adaptive slot 12.

[0045] The adaptive slot 12 provides an adaptive space for the sliding block 9, and the circumferential reserved gap can avoid the horizontal displacement of the sliding block 9 caused by the fixed column 7 during an earthquake, thereby avoiding the direct collision of the sliding block 9 with the lower structure 3. At the same time, the slot wall of the adaptive slot 12 can block external debris from entering the sliding surface, preventing the sliding block 9 from being stuck, and ensuring smooth operation of the horizontal sliding mechanism. In addition, the design of the slot bottom of the adaptive slot 12 being flush with the structure completion surface 13 ensures that the embedded part 10 is tightly attached to the structure layer of the lower structure 3 during installation, thereby improving the connection stability. The slot top of the adaptive slot 12 being flush with the building completion surface 14 realizes seamless connection between the structure and the building surface layer, does not affect ground passage and decoration aesthetics, and adapts to the installation requirements of various building scenes. The vertical limiting effect of the adaptive slot 12 on the sliding block 9 can evenly transmit the vertical load of the fixed column 7 to the lower structure 3 through the sliding block 9 and the embedded part 10, thereby preventing the sliding mechanism from losing stability vertically and causing the fixed column 7 to tilt, and ensuring the installation accuracy of the roller shutter mechanism.

[0046] At the same time, in the event of a fire, the adaptive slot 12 can form a closed heat insulation cavity, and the slot wall can slow down the transmission speed of high temperature to the embedded part 10 and the sliding block 9. At the same time, the sliding block 9 is embedded in the slot, which can prevent falling objects in a fire from directly impacting the sliding surface, prevent the sliding mechanism from failing to cause the roller shutter guide rail 8 to deform, and indirectly improve the fireproof integrity of the fireproof roller shutter.

[0047] Please refer to Figure 12 On the basis of the original adaptive slot 12 structure, a sliding cover plate 15 is added as an upper end sealing member of the adaptive slot 12, forming a composite protection structure of an embedded slot body and a sliding sealing.

[0048] The lower end surface of the sliding cover plate 15 forms a face contact type sliding fit with the slot top edge of the adaptive slot 12, ensuring that the cover plate can move freely and closely along the slot opening. The middle part of the sliding cover plate 15 is provided with a circular, square or irregular shaped through hole matching the outer circumference of the fixed column 7. The inner wall of the through hole is coated with wear-resistant material or directly welded and fixed. After the through hole is sleeved on the lower outer circumference of the fixed column 7, the through hole and the fixed column 7 are connected in a follow-up manner. When the fixed column 7 produces horizontal displacement due to earthquake and other working conditions, the fixed column 7 can drive the sliding cover plate 15 to slide along the slot opening of the adaptive slot 12 through the inner wall of the through hole. During the entire displacement process, the coverage range of the sliding cover plate 15 is always fully overlapped with the slot opening of the adaptive slot 12, maintaining a continuous sealing state of the adaptive slot 12. At the same time, the upper end surface of the sliding cover plate 15 is flush with the building completion surface 14 of the lower structure 3, forming a ground connection with no height difference.

[0049] The sliding cover plate 15 realizes full sealing protection of the adaptation groove 12, completely blocks the channel of dust, sand, construction residues and other sundries into the inside of the adaptation groove 12, avoids the problems of abrasion and jamming between the sliding block 9 and the embedded part 10 caused by the accumulation of sundries, and greatly improves the service life and working reliability of the horizontal sliding mechanism. At the same time, the sliding cover plate 15 can effectively prevent liquid (such as cleaning water, fire accumulation water, etc.) from seeping into the adaptation groove 12, prevent the embedded part 10 and the sliding block 9 from rusting, and ensure the smoothness of horizontal sliding during an earthquake, providing stable protection for displacement compensation of the fixed column 7. The design of the sliding cover plate 15 being flush with the building finish surface 14 and sliding synchronously solves the problems of insufficient ground flatness and easy tripping caused by the exposed slot opening of the traditional adaptation groove 12, meets the daily use requirements of personnel passing and equipment moving, and is especially suitable for places with high personnel density or high frequency operation, such as shopping malls, hospitals and factories.

[0050] In addition, when an earthquake occurs, the sliding cover plate 15 synchronously horizontally displaces with the fixed column 7, always maintains the plugging of the adaptation groove 12, and avoids the building debris generated by the earthquake from entering the groove body; then when a fire occurs, even if the fixed column 7 is offset due to the earthquake, the cover plate can still tightly cover the slot opening, preventing the flame and smoke from spreading through the adaptation groove 12, and ensuring the coordinated play of the seismic isolation and fireproof functions.

[0051] In daily use, if an accidental impact such as equipment collision or personnel falling occurs, the sliding cover plate 15 can serve as a buffer protection member at the lower part of the fixed column 7. The impact load first acts on the sliding cover plate 15, which disperses the load to the groove wall of the adaptation groove 12 through the sliding fit with the slot opening, avoiding the deformation or fracture of the fixed column 7 caused by the direct action of the impact load; at the same time, the rigid structure of the sliding cover plate 15 can effectively protect the sliding mechanism inside the adaptation groove 12 from being damaged by impact, thereby forming the above-mentioned double protection and improving the daily use safety of the structure.

[0052] Please refer to Figure 6 and Figure 12 , which are optimized on the basis of the original adaptation groove 12 to form a multi-layer composite structure of the adaptation groove 12, the buffer groove, the plugging cover plate 17 and the sealing part 19, which cooperates with the overall layout system of the fireproof curtain. Among them, the buffer groove is opened at the upper end of the adaptation groove 12 and coaxially communicated with the adaptation groove 12, and the inner diameter size is larger than that of the adaptation groove 12, forming a stepped groove structure with wide upper and narrow lower, the groove bottom is connected and communicated with the groove top of the adaptation groove 12, and the groove top is flush with the building finish surface 14 of the lower structure body 3, ensuring smooth transition of the structure.

[0053] The blocking cover plate 17 is a circular plate-shaped member matched with the buffer groove, horizontally arranged in the buffer groove, and the outer diameter is smaller than the inner diameter of the buffer groove. The center of the lower end face is fixedly connected with a vertically extending connecting plate 18, and the lower end of the connecting plate 18 is rigidly connected with the top surface of the sliding block 9 of the horizontal sliding mechanism, forming an integrated linkage structure of the cover plate, the connecting plate 18 and the sliding block 9. The middle part of the blocking cover plate 17 is provided with a through hole matched with the outer peripheral size of the fixed column 7. The inner wall of the through hole is coated with wear-resistant material or directly welded in a fixed manner. After the through hole is sleeved on the outer periphery of the lower part of the fixed column 7, the blocking cover plate 17 is matched between the through hole and the fixed column 7 to realize follow-up constraint. The space between the inner wall of the buffer groove and the outer peripheral wall of the blocking cover plate 17 is filled with a sealing part 19 made of fireproof sealing glue filling material with excellent high-temperature resistance and elasticity, which is tightly arranged around the outer periphery of the blocking cover plate 17. After filling, the upper end face of the sealing part 19 is flush with the top of the buffer groove, and forms a tight sealing state with the blocking cover plate 17 and the inner wall of the buffer groove. The sealing part 19 is made of a high-temperature resistant fireproof material 21, which can form an expanded sealing layer after being exposed to fire, fill the gap caused by the displacement of the blocking cover plate 17, and block the spread of high-temperature smoke and flame through the groove body. In addition, the heat insulation property of the sealing part 19 can reduce the heat diffusion from the inside of the groove to the outside, avoiding thermal damage to the surrounding structure.

[0054] Please refer to Figure 5 The blocking cover plate 17 is arranged in two pieces of brittle fireproof plates with symmetrical specifications. The plate material is selected from brittle fireproof materials 21 such as calcium silicate plate or fiber reinforced cement plate which can maintain structural integrity at high temperature. A semicircular notch is formed on one side edge of a single fireproof plate. After the two plates are buckled, the notches are combined to form a circular through hole matched with the outer peripheral size of the fixed column 7, realizing the tight sleeving of the lower part of the fixed column 7. A gap of 1-2 mm is reserved between the buckling surfaces of the two brittle fireproof plates, which not only avoids installation interference, but also provides a small buffer for subsequent displacement.

[0055] The sealing part 19 is made of fireproof sealing glue with excellent elasticity, which is uniformly filled between the circumferential edges of the two brittle fireproof plates and the circumferential inner wall of the buffer groove. After filling, the upper end face of the sealing glue is flush with the top of the buffer groove and the top surface of the fireproof plate, forming a closed surface seamlessly connected with the ground. At the same time, the sealing glue is tightly bonded with the fireproof plate and the inner wall of the buffer groove, ensuring the initial sealing performance.

[0056] If the displacement exceeds the elastic limit of the sealing glue due to high-intensity earthquake, the brittle fireproof plate will produce controllable fracture along the preset micro gap or weak link, which not only releases the displacement stress to avoid damage to the fixed column 7, but also provides basic support for the fixed column 7 through the characteristic that the broken plate fragments are still connected with the sliding block 9. Subsequently, when the fire occurs, the fireproof sealing glue at the fracture site expands to fill the gap caused by the fracture of the plate, and the fragments can still act as a support framework of the sealing layer, ensuring that the sealing and fireproof functions are not invalidated, solving the problem of sealing failure caused by excessive displacement of the traditional structure.

[0057] Please refer to Figure 11 , the blocking cover plate 17 is an integrally formed rigid plate, the middle part of the rigid plate is welded and fixed with the fixed column 7, and the sealing part 19 is a flexible filling material filled between the circumferential edge of the rigid plate and the circumferential edge of the buffer groove. The blocking cover plate 17 is made of high-strength metal materials such as Q235 steel or stainless steel into an integrally formed rigid plate, and the thickness of the plate is set according to the diameter of the fixed column 7 and the stress requirement, to ensure sufficient structural rigidity. A circular through hole matching the outer diameter of the fixed column 7 is formed in the middle part of the rigid plate, and the lower part of the fixed column 7 penetrates through the through hole during installation, and the two are connected by full welding process, and the height of the welding seam is not less than the thickness of the plate, forming a rigid integrated structure of the fixed column 7 and the rigid plate.

[0058] The outer diameter of the rigid plate is smaller than the inner diameter of the buffer groove, and after installation, the lower end surface of the rigid plate is tightly attached to the top surface of the slider 9 of the horizontal sliding mechanism (non-rigid connection, only forming a surface support), and an annular gap of 10-15mm is reserved between the circumferential edge and the inner wall of the buffer groove. The sealing part 19 is made of flexible filling material (such as ceramic fiber rope wrapped with fireproof silicone strip or elastic fireproof caulking material) with high temperature resistance and high elasticity, 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 surface 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 seamlessly connected with the ground, and at the same time, the flexible material itself is elastically deformed to tightly attach and seal with the rigid plate and the inner wall of the buffer groove.

[0059] The welding of the integrally formed rigid plate and the fixed column 7 makes the two form a rigid whole without relative displacement, and the surface support of the lower end surface of the rigid plate and the slider 9 can effectively resist the lateral bending moment of the fixed column 7 caused by its own weight, wind or vibration during the lifting of the roller shutter, greatly weakening the lateral sway of the fixed column 7. This supporting effect is directly transmitted to the roller shutter guide rail 8, ensuring that the guide rail always maintains verticality, avoiding problems such as jamming, deviation or excessive sealing gap of the roller shutter plate during lifting.

[0060] As the blocking main body, the rigid plate can effectively block the impact of heavy objects, the trampling of people and the crushing of large equipment, preventing the damage of the core components such as the slider 9 and the embedded part 10 inside the groove body; at the same time, the sealing property of the rigid plate can completely block the entry of dust, sand, liquid and other sundries into the adaptive groove 12, preventing the wear and rust of the sliding surface and prolonging the service life of the sliding mechanism. The high elasticity of the flexible filling material can adapt to the horizontal displacement of the rigid plate with the fixed column 7, and within the range of normal seismic displacement (≤60mm), the material only deforms elastically without damage, always filling in the gap between the rigid plate and the buffer groove, maintaining the continuity of sealing and protection.

[0061] Please refer to Figure 6 and Figure 12The embedded part 10 is a horizontally arranged stainless steel plate, and the upper surface of the embedded part 10 is coated with a sliding material 20. The embedded part 10 is horizontally arranged by using a 304 or 316L stainless steel plate, and is rigidly connected with the lower structure 3 by means of a bonded rebar to ensure the stability of the bearing. The upper surface of the stainless steel plate is polished, and then uniformly coated with a 2-3 mm thick special sliding material 20 (such as a polytetrafluoroethylene coating or a modified epoxy resin sliding coating). The flatness error of the coating surface is controlled to be within 0.5 mm / m, so as to form a low-friction sliding surface. The sliding block 9 of the horizontal sliding mechanism is made of wear-resistant alloy steel, and the lower end surface of the sliding block 9 is tightly attached to the sliding coating to form a sliding pair. The upper end surface of the sliding block 9 is tightly attached to the lower end surface of the integrally formed rigid sealing plate.

[0062] Please refer to Figure 3 , Figure 4 , Figure 9 and Figure 10 The fixed column 7 and the roller shutter guide rail 8 are wrapped with fireproof material 21 around the periphery, and the outer periphery of the fireproof material 21 is sealed and installed with fireproof plate 22. The fixed column 7 is wrapped with fireproof and heat-insulating material (such as alkali-free glass wool felt or intumescent fireproof coating) around the periphery from below the connection between the upper part and the upper pier 2 to above the connection between the lower sliding block 9, and a mounting gap is reserved for the roller shutter guide rail 8 during wrapping. The roller shutter guide rail 8 is fixed to the opposite side wall of the fixed column 7, and the side wall and the upper and lower end portions exposed to the outside are wrapped with the same specification fireproof material 21 to ensure that there is no blind area for protection at the connection node of the guide rail and the fixed column 7.

[0063] The outer periphery of the fireproof and heat-insulating material is sealed and installed with fireproof plate 22 (such as fiber reinforced cement fireproof plate or calcium silicate fireproof plate), and the fireproof plate 22 is connected and fixed with the fixed column 7 by means of fireproof bolts. The joint of the plate is treated by filling the joint with fireproof sealant, and the upper and lower ends of the fireproof plate 22 are seamlessly connected with 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.

[0064] Please refer to Figure 7 and Figure 12, the first fixed track and the second fixed track 26 are arranged in parallel and spaced apart in the reserved gap, the first fixed track and the second fixed track 26 are both longitudinally extended, the upper end of the first fixed track and the upper end of the second fixed track 26 are both connected with the upper part of the fixed column 7, and the flexible fireproof cloth 27 is arranged between the first fixed track and the second fixed track 26. The first fixed track and the second fixed track 26 are arranged in parallel and spaced apart in the reserved gap, both of which are formed by bending 10mm-thick stainless steel plates and have a “U”-shaped cross section, and the openings are oppositely arranged.
