[0001] The invention relates to the technical field of suspended ceiling wire tubes, in particular to an ALC board fire protection suspended ceiling and an installation method. Background Art

[0002] ALC board fire ceiling is a ceiling made of ALC material, that is, the ceiling.

[0003] ALC is the abbreviation of autoclaved lightweight concrete, which is a type of high-performance autoclaved aerated concrete (ALC). ALC board is made of fly ash (or silica sand), cement, lime and other raw materials. It is a porous concrete molding board cured by high-pressure steam. It contains treated steel reinforcement and can be used as wall material or roof panel. It is a new building material with superior performance, good thermal insulation, sound insulation, fire resistance and durability.

[0004] Existing ceiling disassembly structures mostly rely on elastic restraints or interference fits. While these types of disassembly structures facilitate disassembly, their main restraint structures are susceptible to deformation or loss of elasticity after being exposed to fire, making the ceiling prone to falling in the event of a fire. Since the ceiling is prone to falling during a fire, people escaping from the room and rescue workers are at risk of being injured by the falling ceiling. Summary of the Invention

[0007] Furthermore, the emergency locking mechanism includes four groups of limit blocks arranged at the bottom of the support beam, and a single group of limit blocks includes a plurality of limit blocks arranged at equal distances; The limit block is arranged in a circle, and a transmission shaft is fixed at the center thereof, the transmission shaft passes through the support beam and is rotatably connected thereto, the transmission shaft is connected to a synchronizer installed in the assembly groove, and the synchronizer is connected to a trigger installed in the assembly groove; The four sides of the ceiling body are all provided with limiting grooves that cooperate with the limiting blocks, and the four sides of the ceiling body are also provided with notches that communicate with the limiting grooves.

[0008] Furthermore, the notch between two adjacent ceiling bodies forms a through slot, and the width of the through slot is greater than the width of the limiting block; The limiting groove between two adjacent ceiling bodies forms a pulling groove, and the width of the pulling groove is greater than the length of the limiting block.

[0009] Furthermore, the synchronizer comprises four slides slidably mounted in the assembly groove, each of the four slides is provided with a rectangular groove, a rack is provided on one side of the inner wall of the rectangular groove, and the rack is meshed with a plurality of number one gears coaxially fixed on the transmission shaft; The slide plate is connected to the trigger member.

[0010] Furthermore, the trigger member includes a transmission disc rotatably mounted on the assembly groove, and four transmission plates are rotatably mounted on the eccentric portion of the transmission disc at equal intervals, and the transmission plates are rotatably connected to the slide plate; A worm wheel is coaxially fixed to the rotating shaft of the transmission disc, and a worm screw meshing with the worm wheel is rotatably mounted on one side of the worm wheel; A cylinder is fixed on both sides of the worm gear, a piston is sealingly and slidingly installed in the cylinder, a rack plate is coaxially fixed on the side of the piston facing the cylinder port, and the rack plate is meshed with the No. 2 gear coaxially fixed on the worm; A supporting member is fixed in the assembly groove, the rack plate is placed on the supporting member, and two integrally formed limiting bars are fixed on the supporting member, and the rack plate is limited by the limiting bars; A heat conducting member is installed on the cylinder body.

[0011] Furthermore, the heat conducting member includes four slots that are inserted into the assembly slot, and the four slots are connected by a heat collecting portion. Two embedding slots are provided at the bottom of the heat collecting portion, and a heat conducting rod No. 1 arranged in a spiral shape is embedded in the embedding slot. The heat conducting rod No. 1 is connected and fixed to the heat conducting rod No. 2 wound on the cylinder body, and a piston is formed by the heat conducting rod No. 1 and the heat conducting rod No. 2; A bending portion is provided at the connection between the heat collecting portion and the heat conducting plate; The thickness of the heat conducting plate is greater than that of the heat collecting part.

It is also highly stable, firmly and reliably securing the ceiling body and support beams, and will not fail due to vibrations caused by the spread of fire. Furthermore, the mechanism does not affect the normal installation and removal process of the ALC fire ceiling, ensuring convenience during routine maintenance and replacement. 3. The ALC board fire ceiling can decide whether to activate the trigger according to the severity of the fire through the heat conduction element in the emergency locking mechanism; When the fire is under control, the ceiling can be dismantled to prevent it from spreading. This design avoids the problem of the ceiling being unable to be dismantled after a fire. When the fire is uncontrollable, that is, there are no firefighters to extinguish the fire and the fire cannot be effectively controlled, the trigger is activated.

[0019] Fourth, the ALC board fire ceiling adopts a purely mechanical structure to achieve the above technical effects, avoiding the auxiliary work of electronic equipment and preventing electronic equipment from malfunctioning in the event of a fire. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figures 1-14 The embodiment of the present invention provides a technical solution: an ALC board fire ceiling, comprising a support beam 2, the support beam 2 being arranged in a "cross" shape, a mounting groove 201 being opened on the support beam 2, an emergency locking mechanism being installed in the mounting groove 201, and a travel limit block 7 being fixed at the intersection of the bottom of the support beam 2; The ceiling body 1 is mounted on the bottom of the support beam 2 through a disassembly member, and the ceiling body 1 is also connected to an emergency locking mechanism; The ceiling body 1 is rectangular, and the top is hollowed out to form a sunken groove; The disassembly part includes an assembly block fixed to the four sides of the sunken groove, and the assembly block cooperates with two assembly claws 6 fixed relatively to the bottom of the support beam 2. The bottom of the assembly claw 6 is provided with a support portion; the support portion refers to the inclined part at the end of the assembly claw 6; The assembly block includes a first tilted block 604 and a second tilted block 606 arranged opposite to the first tilted block 604 . The tilt angle of the second tilted block 606 is smaller than that of the first tilted block 604 .

[0023] In the embodiment of the present invention, during installation, the installer lifts the ceiling body 1 and pushes the assembly block of the ceiling body 1 between the two assembly claws 6; When the ceiling body 1 is lifted and pushed, the ceiling body 1 is in an upright upward motion state, so that the assembly blocks (i.e., the first tilted block 604 and the second tilted block 606) are driven to rise with the ceiling body 1. When the first tilted block 604 rises to the point where it contacts the supporting portion of the assembly claw 6, the inclined surface of the first tilted block 604 drives the assembly claw 6 and the supporting portion of the assembly claw 6 to bend and deform, thereby storing elastic potential energy. After the first tilted block 604 and the second tilted block 606 pass through, the elastic potential energy of the assembly claw 6 is released, driving the assembly claw 6 and the supporting portion of the assembly claw 6 to reset. The supporting portion of the assembly claw 6 drags the second tilted block 606, so that the assembly blocks and the ceiling body 1 are limited in position, and the ceiling body 1 will not fall due to its own gravity when the force lifting and pushing the ceiling body 1 disappears. The second tilting block 606 has a smaller inclination angle than the first tilting block 604, so that the force required to drive the assembly claw 6 to bend by the second tilting block 606 is smaller, thereby saving more effort during installation. The second tilting block 606 has a smaller inclination angle than the first tilting block 604, so that the support portion of the assembly claw 6 needs to have a greater force to drive the assembly claw 6 to bend when dragging the second tilting block 606, so that when the force of lifting and pushing the ceiling body 1 to rise disappears, the ceiling body 1 and the assembly block will not fall, because the drag of the second tilting block 606 and the assembly claw 6 is actually still in the inclined surface. When disassembling the ceiling body 1, it is only necessary to use the disassembly related tools to adsorb the ceiling body 1 and then pull the ceiling body 1 vertically downward to disassemble the ceiling body 1; the related tools can be suction cups or other adsorption structures; This disassembly method has the advantages of labor-saving installation, simple disassembly, and simple structure. However, there is a disadvantage in this type of disassembly structure, including but not limited to the method provided by the present invention. Since the installation is all elastic fit or interference fit, in the event of a fire, the fire will cause the loading and unloading mechanism to lose elasticity and deformation, which will cause the disassembly structure to lose its deformation force, and thus cause the ceiling body 1 to fall with a high probability. This situation is extremely dangerous to both the trapped people in the house and the rescue workers in the event of a fire. The existing ceiling structure does not take this problem into consideration and does not have a corresponding structural method. The solution of the present invention is to fix the ceiling body 1 and the support beam 2 through an emergency locking mechanism so that the support beam 2 and the ceiling body 1 will not separate due to fire, and the locking is based on the temperature change during a fire. When there is no fire, the emergency locking mechanism does not work, and the loading and unloading work between the ceiling body 1 and the support beam 2 is similar to that of a common loading and unloading structure.

[0024] The emergency locking mechanism includes four groups of limit blocks 601 arranged at the bottom of the support beam 2, and a single group of limit blocks 601 includes a plurality of limit blocks 601 arranged at equal distances; The limit block 601 is arranged in a circle, and a transmission shaft 602 is fixed at the center thereof. The transmission shaft 602 passes through the support beam 2 and is rotatably connected thereto. The transmission shaft 602 is connected to a synchronizer installed in the assembly groove 201, and the synchronizer is connected to a trigger installed in the assembly groove 201. The four sides of the ceiling body 1 are provided with limiting grooves 605 that cooperate with the limiting blocks 601 , and the four sides of the ceiling body 1 are also provided with notches 603 that communicate with the limiting grooves 605 .

[0025] In the embodiment of the present invention, when a fire occurs, the temperature rises due to the fire, triggering the triggering member, which drives the synchronizing member to work, and the synchronizing member drives all the transmission shafts 602 to rotate synchronously, so that the transmission shafts 602 drive the limit block 601 to rotate 90 degrees, so that the limit block 601 moves into the limit groove 605 to limit the ceiling body 1 in the vertical direction. The function of the notch 603 is to allow the limit block 601 to enter the position of the limit groove 605 through the notch 603 when the ceiling body 1 is installed. Secondly, when the transmission shaft 602 and the limit block 601 are not rotating, the normal disassembly of the ceiling body 1 is not affected; It should be noted that in order to prevent the ceiling body 1 from falling, the ceiling body 1 must be in a state where it is completely installed. Then, the ceiling body 1 will be horizontally limited by other adjacent ceiling bodies 1. In other words, the ceiling body 1 will not move horizontally after it is installed. The reason why the ceiling body 1 falls is that the assembly claws 6 are deformed or lose their elasticity due to fire, which causes the ceiling body 1 to lose its limit and fall. The present invention realizes the limit locking of the vertical direction of the ceiling body 1 through the cooperation of the limit block 601 and the limit groove 605, so that after the assembly claw 6 is dead and limited, the limit block 601 pulls the ceiling body 1 to prevent it from falling.

[0026] The notch 603 between two adjacent ceiling bodies 1 forms a through slot, and the width of the through slot is greater than the width of the limiting block 601; The limiting groove 605 between two adjacent ceiling bodies 1 forms a pull groove, and the width of the pull groove is greater than the length of the limiting block 601.

[0027] The synchronizer includes four slides 402 slidably mounted in the assembly slot 201 . Each of the four slides 402 has a rectangular slot. A rack 405 is provided on one side of the inner wall of the rectangular slot. The rack 405 meshes with a plurality of number one gears 403 coaxially fixed to the transmission shaft 602 . The slide plate 402 is connected to the trigger member.

[0028] In the embodiment of the present invention, when the trigger member is working, the four slides 402 are pulled or pushed synchronously to slide synchronously, so that when the slides 402 move, the engagement of the rack 405 with the first gear 403 drives the multiple transmission shafts 602 and the limit block 601 to rotate synchronously; Among them, the method of synchronously driving multiple shafts and meshing of gears and racks is the simplest, and the transmission accuracy is also relatively high.

[0029] The triggering member includes a transmission disc 4 rotatably mounted on the assembly slot 201. Four transmission plates 401 are rotatably mounted on the eccentric portion of the transmission disc 4 at equal intervals. The transmission plates 401 are rotatably connected to the slide plate 402. A worm gear 404 is coaxially fixed to the rotating shaft of the transmission disc 4, and a worm 502 meshing with the worm gear 404 is rotatably mounted on one side of the worm gear 404; Cylinders 5 are fixed on both sides of the worm gear 404. Pistons 505 are sealed and slidably installed in the cylinders 5. A rack plate 501 is coaxially fixed to the side of the piston 505 facing the end of the cylinder 5. The rack plate 501 meshes with the second gear 503 coaxially fixed to the worm 502. A supporting member 504 is fixed in the assembly groove 201, and the rack plate 501 is placed on the supporting member 504. Two integrally formed limiting bars 506 are fixed on the supporting member 504, and the limiting bars 506 limit the sliding position of the rack plate 501; A heat conducting member is installed on the cylinder body 5 .

[0030] In the embodiment of the present invention, at least 50% of expansion oil needs to be added to the cylinder 5 during construction; When a fire occurs, the heat from the fire is transferred to the cylinder 5 through the heat conducting member, raising the temperature of the cylinder 5 so that the expansion oil inside it can be added. The heated expansion oil pushes the piston 505 and the rack plate 501 to move. When the rack plate 501 moves, it meshes with the second gear 503 to drive the worm 502 to rotate. When the worm 502 rotates, the four slide plates 402 are synchronously pulled or pushed toward or away from the axis of the transmission plate 401. The expansion oil mentioned above refers to thermal oil, also known as heat transfer oil, a specialized oil widely used in industrial production. Its primary function is to transfer heat at high temperatures. Thermal oil has the characteristics of good thermal stability, strong oxidation resistance, low viscosity, and high heat transfer efficiency.

[0031] The expansion coefficient of expansion oil (thermal oil) is between 6.710-4 and 1.1910-4. That is, when the temperature rises, the volume of the thermal oil will expand; when the temperature drops, the volume of the thermal oil will shrink. The expansion volume calculation should be no less than 20% of the total amount of heat transfer oil in cylinder 5. In addition, in the expansion design, it should be noted that the volume of heat transfer oil expands by 7% for every 100 degrees increase in temperature. That is, as the expansion oil (heat transfer oil) is heated, its volume expands to push the piston 505 to move axially; Assume that the density of the expansion oil (thermal oil) at 20°C is ρ1 = 880 kg / m³, and at 300°C is ρ2 = 660 kg / m³. The volume expansion percentage is ≈ [(880 / 660) - 1] * 100% ≈ [1.333 - 1] * 100% ≈ 33.3%. This means that when heated from 20°C to 300°C, the volume of the thermal oil expands by approximately 33.3%. For example, if cylinder 5 is cold and contains 1 cubic meter of oil at 20°C, its volume will expand to approximately 1.333 cubic meters at an operating temperature of 300°C. Therefore, when the expansion oil (thermal oil) is heated, it is sufficient to propel piston 505 axially a certain distance.

[0032] The expansion of the expansion oil drives the synchronous movement of the four No. 1 gears 403. The movement of the No. 1 gear 403 corresponds to the rotation of the limit block 601. In the event of a fire, the limit block 601 is driven to rotate and limit the position of the limit block 601. Among them, since some items may fall due to the fire, in order to prevent the vibration of the fall from causing the limit block 601 to rotate or the skateboard 402 to move in the opposite direction, the present invention increases the torque by engaging the worm gear 404 with the worm 502 so that the rotational force of the transmission disk 4 is sufficient to pull or push the skateboard 402, and at the same time applies a self-locking force to the transmission disk 4, so that the transmission disk 4 will not rotate due to vibration, and thus the skateboard 402 and the transmission plate 401 also have a locking force.

[0033] The limiting bar 506 and the supporting member 504 are used to limit and guide the rack plate 501 to prevent the rack plate 501 from tilting during sliding, which may cause the rack plate 501 to be disengaged from the second gear 503.

[0034] The heat conducting member includes four slots 303 that are inserted into the assembly slot 201. The four slots 303 are connected by the heat collecting portion 301. The heat collecting portion 301 has two embedded slots 304 at the bottom. A spiral-shaped heat conducting rod No. 1 is embedded in the embedded slots 304. The heat conducting rod No. 1 is connected and fixed to the heat conducting rod No. 2 wound around the cylinder 5. The heat conducting rod No. 1 and the heat conducting rod No. 2 form a piston 505. A bending portion 305 is provided at the connection between the heat collecting portion 301 and the heat conducting plate 3; The thickness of the heat conducting plate 3 is greater than that of the heat collecting portion 301 .

[0035] A fitting groove 507 is provided on the side of the second heat conducting rod facing the cylinder 5 .

[0036] By providing a fitting groove 507 on the second heat conducting rod, the contact surface between the fitting groove 507 and the cylinder 5 is increased to improve the heat conduction efficiency; In the embodiment of the present invention, when a fire occurs, heat is conducted through four heat conducting plates 3 with a larger area, which transfer the heat to the heat collecting portion 301, and then transfer the temperature to the cylinder 5 through the piston 505; Among them, there are controllable fires and uncontrollable fires. Usually, the fire is in the controllable period within a short period of time after it starts. During the controllable period, it can be considered that the fire can be controlled and extinguished. To address this issue, existing similar technologies mostly trigger the device immediately upon detecting temperature or flame, while the present invention does not trigger the device during the controllable period, but triggers the device when the controllable period transitions to the uncontrollable period. The heat conducting plate 3 of the present invention is thicker than the heat collecting portion 301 and has a relatively large area. Therefore, the heat conducting plate 3 heats up relatively slowly and does not heat up rapidly during the controllable fire period. Consequently, the temperature is not quickly transferred to the heat collecting portion 301 and the piston 505. During this period, the ceiling body 1 can be disassembled to extinguish the fire. When the fire reaches an uncontrollable state, the temperature of the heat conducting plate 3 also rises to a relatively high state, thereby allowing the temperature to be transferred to the heat collecting portion 301 and the piston 505. The thickness of the heat collecting portion 301 is relatively thin, and the heat conduction efficiency is relatively high. The bent portion 305 in this embodiment is to prevent the heat collecting portion 301 from transmitting dryness to the transmission disc 4 and the transmission plate 401; It should also be noted that honeycomb-shaped punching holes are provided on the support beam 2 to improve the contact between the fire and the heat conducting plate 3 , thereby preventing the fire from burning only the support beam 2 but not the heat conducting plate 3 .

[0037] A groove 302 is formed at the bottom of the heat conducting plate 3 , and the slide plate 402 slides in the groove 302 , and the groove 302 is used to linearly limit the slide plate 402 .

[0038] In the embodiment of the present invention, the slide plate 402 can be linearly limited by the groove 302, so that the slide plate 402 can move linearly when being pulled or pushed.

[0039] Both sides of the heat conducting plate 3 are provided with a clamping groove 303 , which is slidably matched with the clamping block 202 fixed in the assembly groove 201 .

[0040] In the embodiment of the present invention, during installation, the heat conducting plate 3 can be fixed by directly sliding the slot 303 of the heat conducting plate 3 into the groove 302, so that the first gear 403 will not drive the heat conducting plate 3 to move synchronously due to friction. Moreover, this installation method is faster and does not require bolt fixing.

[0041] like Figure 2As shown, the emergency locking mechanism of the present invention locks the ceiling, and not only four ceiling bodies 1. The present invention is only for illustrating the structure. The length of the support beam 2 can be extended and corresponding structures for locking and transmission can be added, so that one emergency locking mechanism can lock a row of multiple ceiling bodies 1 in the event of a fire.

[0042] The present invention also provides an ALC board fire ceiling installation method, which uses an ALC board fire ceiling and includes the following steps: Step 1: Lift the ceiling body 1 and push the ceiling body 1 to rise upright; Step 2: When the ceiling body 1 is erected and raised, the first tilt block 604 cooperates with the supporting portion of the assembly claw 6 to drive the assembly claw 6 to bend elastically, making way for the first tilt block 604 and the second tilt block 606 to pass through; Step 3: When the ceiling body 1 moves to the end of its travel, the assembly claw 6 returns to its position to limit the second tilting block 606 to complete the installation of the ceiling body 1.
