Description

Technical Field

[0001] The present invention relates to the technical field of green buildings, and particularly to a thermal insulation and fireproof structure for the concrete exterior wall of a green building. Background Art

[0002] A green building refers to a building that, throughout its entire life cycle (including planning, design, construction, operation, demolition, and reuse), maximally saves resources (energy, land, water, and materials), protects the environment, and reduces pollution, providing people with a healthy, applicable, and efficient usable space and being in harmonious coexistence with nature. A concrete exterior wall refers to the exterior wall of a building that uses concrete materials as the main structural and enclosing components. It is formed by on-site casting or prefabricated assembly and has good load-bearing capacity, durability, and protection performance. Concrete exterior walls are widely used in various buildings and are one of the common exterior wall forms in modern architecture. The concrete exterior wall not only bears the structural load of the building but also plays an enclosing role, effectively resisting the invasion of natural factors such as wind, rain, and snow. Through reasonable design, the concrete exterior wall can meet the requirements of building thermal insulation, heat insulation, waterproofing, and fireproofing.

[0003] After retrieval, it is found that there are problems with the thermal insulation and fireproof structure of the concrete exterior wall in the prior art. Since the prior art often uses thermal insulation and fireproof composite boards to improve the fireproof and thermal insulation effects of the concrete exterior wall, however, the physical and chemical stability of the constituent materials of some thermal insulation and fireproof composite boards is poor, and they are prone to deformation, cracking, or peeling during the construction process due to the influence of high temperature and humidity. In addition, the thermal insulation and fireproof systems of traditional exterior walls are separated, with poor integrity and prone to weak links. Secondly, when a fire breaks out on the concrete exterior wall, it is difficult for the concrete exterior wall to suppress the flames and cannot separate the flames, resulting in the flames possibly spreading gradually along the concrete exterior wall, causing a fire risk and poor fireproof and thermal insulation effects. Therefore, based on the above retrieval and combined with the prior art, a thermal insulation and fireproof structure for the concrete exterior wall of a green building is proposed to solve the above problems.

Specific implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In a typical implementation mode of the present application, please refer to Figures 1 to 11 , a concrete exterior wall thermal insulation and fire prevention structure for a green building, including a wall body 1, a plurality of thermal insulation boards 2 are installed on the left side of the wall body 1. The thermal insulation boards 2 are specifically foam concrete fireproof thermal insulation boards. The foam concrete fireproof thermal insulation boards utilize the incombustibility of cement and a large number of closed pores to achieve fire prevention, light weight and thermal insulation effects. Its combustion performance reaches Class A, and it has excellent water resistance and interface performance, and is convenient for construction. A protective net 7 is arranged on the left side of the thermal insulation board 2, a concrete layer 8 is arranged on the left side of the protective net 7, and a thermal insulation and fire prevention mechanism 3 is arranged on the left side of the concrete layer 8 for thermal insulation and fire prevention. A plurality of fireproof boards 4 are arranged on the left side of the concrete layer 8 to improve the fireproof performance of the wall body 1;

[0033] The heat insulation and fire prevention mechanism 3 includes two support pipes 11, both of the two support pipes 11 are installed on the left side of the concrete layer 8. One side of the fireproof board 4 is movably sleeved with a cover plate 12. The cover plate 12 is a circular structure made of metal and has good heat conduction performance. A communication hole 24 is provided on one side of the fireproof board 4. The outer circumferential wall surface of the cover plate 12 is movably sleeved with the inner circumferential wall surface of the communication hole 24. A plurality of guide frames 28 are fixedly installed on the right side of the cover plate 12. An air delivery pipe 29 is fixedly installed on the outer circumferential wall surface of the support pipe 11. A first plug 30 for blocking the air delivery pipe 29 is fixedly installed on the right side of the cover plate 12. The outer circumferential wall surface of the first plug 30 is movably sleeved with the inner circumferential wall surface of the air delivery pipe 29. A plurality of support boxes 23 are fixedly installed on the left side of the concrete layer 8. The bottom surface of the support box 23 is rotatably connected by a hinge with a bottom plate 33. A heat conduction plate 40 is slidably connected inside the support box 23. A heat conduction rod 39 is fixedly installed on the left side of the heat conduction plate 40. The left end of the heat conduction rod 39 is fixedly connected with one side of the cover plate 12. Heat expansion microspheres are filled between the heat conduction plate 40 and the support box 23;

[0034] Among them, the heat expansion microspheres are a kind of heat expansion type microcapsule with a core-shell structure, which is composed of a thermoplastic polymer shell wrapping a low-boiling solvent such as liquid alkane gas or other compounds. Its diameter is generally between 10 - 50 μm, and the volume can rapidly expand to dozens of times its own after heating. The heat expansion microspheres filled inside the support box 23 are of medium-temperature expansion type, and the specific expansion temperature is 110 - 160 °C; through the heat expansion microspheres, carbon dioxide can be released when the first plug 30 is separated from the air delivery pipe 29.

[0035] A sealing frame 49 is fixedly sleeved on the outer circumferential wall surface of the fireproof board 4. The sealing frame 49 is made of flame-retardant rubber. Through the sealing frame 49, multiple fireproof boards 4 are tightly connected, reducing the influence of thermal expansion and contraction on the fireproof board 4 and narrowing the gap between multiple fireproof boards 4. A fixed box 36 is fixedly installed on the outer circumferential wall surface of the air delivery pipe 29. A blocking block 50 is rotatably connected to the inner circumferential wall surface of the air delivery pipe 29. A first magnet 34 is fixedly installed on the left side of the blocking block 50. A second magnet 38 is fixedly installed on the right side of the first plug 30. The first magnet 34 and the second magnet 38 attract each other. A first spring 41 for resetting the heat conduction rod 39 and the heat conduction plate 40 is sleeved on the outer circumferential wall surface of the heat conduction rod 39;

[0036] A connecting rod 35 is rotatably connected to the inner top surface of the fixed box 36 through a bearing. The bottom surface of the connecting rod 35 is fixedly connected with the outer circumferential wall surface of the blocking block 50. A clockwork spring 37 is wound around the outer circumferential wall surface of the connecting rod 35. One side of the clockwork spring 37 is fixedly connected with the inner circumferential wall surface of the fixed box 36. The clockwork spring 37 provides the acting force required for the rotation of the blocking block 50. A support roller 31 is rotatably connected to the inside of the guide frame 28 through a bearing. A plurality of movable plates 32 are fixedly installed on the outer circumferential wall surface of the support roller 31. The rotation of the support roller 31 and the movable plates 32 guides and conveys carbon dioxide;

[0037] Among them, when there is a flame burning on the surface of the fireproof board 4, the thermal expansion microspheres inside the support box 23 will expand under the influence of the temperature of the flame. The expansion of the thermal expansion microspheres will drive the heat conduction rod 39 and the cover plate 12 to move outward. The outward movement of the cover plate 12 causes the high-pressure carbon dioxide inside the support tube 11 to be ejected through the gas transmission pipe 29. The ejected carbon dioxide diffuses outward along the surface of the fireproof board 4 through a plurality of guide frames 28 under the blockage of the cover plate 12. The outward diffusion of the carbon dioxide causes the flame on the surface of the fireproof board 4 to be quickly extinguished;

[0038] A second plug 42 is movably sleeved on the top surface of the support box 23. A feed port is opened on the top surface of the support box 23. The outer circumferential wall surface of the second plug 42 is movably sleeved with the inner circumferential wall surface of the feed port. Limiting frames 43 are fixedly installed on both the left and right sides of the bottom plate 33. Two positioning blocks 47 are fixedly installed on the top surface of the support box 23. A support plate 44 is elastically connected to the positioning block 47 through a second spring 46. A clamping column 45 is fixedly installed on the side surface of the support plate 44. The clamping column 45 is movably clamped with the limiting frame 43. The second spring 46 is sleeved on the outer circumferential wall surface of the mounting rod 48. One end of the second spring 46 is fixedly connected to one side of the support plate 44, and the other end of the second spring 46 is fixedly connected to one side of the positioning block 47;

[0039] Correspondingly, after the flame is extinguished, the staff first replaces the fireproof board 4, and then the staff separates the clamping column 45 from the limiting frame 43 by squeezing the support plate 44. This causes the bottom plate 33 to rotate downward. The downward rotation of the bottom plate 33 causes the expanded thermal expansion microspheres in the support box 23 to fall off. At this time, the acting force of the first spring 41 causes the heat conduction rod 39 and the heat conduction plate 40 to drive the cover plate 12 to reset. Then the staff resets the bottom plate 33 and adds new thermal expansion microspheres into the support box 23 through the feed port;

[0040] The reset of the cover plate 12 drives the first plug 30 to move backward into the inside of the gas transmission pipe 29. At this time, the magnet 34 on the gas transmission pipe 29 will magnetically adsorb the magnet 38 on the first plug 30. This causes the blocking block 50 to rotate 90 degrees and horizontally block the heat conduction rod 39, thereby blocking the support tube 11 again.

[0041] Through the above technical features, by providing the heat preservation board 2, a plurality of heat preservation boards 2 are installed on one side of the wall body 1. The heat preservation board 2 can reduce the loss of indoor heat. A protective net 7 is hung on one side of the heat preservation board 2 to increase the adhesion between the heat preservation board 2 and the concrete. Subsequently, the staff uses concrete and a woodworking mold to pour a concrete layer 8 on one side of the protective net 7. The wall body 1 and the concrete layer 8 sandwich the heat preservation board 2 in the middle, avoiding problems such as the heat preservation board 2 falling off and cracking, and at the same time reducing the influence of the external environment on the heat preservation board 2. In addition, the heat preservation board 2 is wrapped by concrete, which can effectively block the fire source and reduce the fire risk;

[0042] Multiple fireproof boards 4 on the side of the concrete layer 8 further enhance the fireproof performance. The staff will connect high-pressure carbon dioxide gas into the interior of the support pipe 11 using a flange. When a fire breaks out and burns on the surface of the fireproof board 4, the heat of the flame will be transferred to the thermally expandable microspheres inside the support box 23 through the cover plate 12, the heat-conducting rod 39, and the heat-conducting plate 40. The thermally expandable microspheres will be heated and squeeze the heat-conducting plate 40. The heat-conducting plate 40 being squeezed drives the heat-conducting rod 39 to move outward, compressing the first spring 41 at the same time. The heat-conducting rod 39 moving outward drives the cover plate 12 to move outward, and the cover plate 12 moving outward drives the first plug 30 to move outward. After the first plug 30 moves outward, the blocking block 50 loses the abutment of the first plug 30, which causes the clockwork spring 37 to be released and drives the connecting rod 35 to drive the blocking block 50 to rotate by 90 degrees. The blocking block 50 rotating by 90 degrees makes the blocking block 50 that was originally horizontally placed inside the gas transmission pipe 29 longitudinally located inside the gas transmission pipe 29. Losing the blockage of the first plug 30 and the blocking block 50, the high-pressure carbon dioxide gas inside the support pipe 11 is ejected through the gas transmission pipe 29. The carbon dioxide sprays along the gas transmission pipe 29 onto the cover plate 12. Due to being blocked by the cover plate 12, part of the carbon dioxide enters the inside of the guide frame 28. The carbon dioxide entering the inside of the guide frame 28 moves forward and drives the movable plate 32 and the support roller 31 to rotate. The support roller 31 and the movable plate 32 rotating guide the carbon dioxide and convey the carbon dioxide forward, which makes the carbon dioxide move along the surface of the fireproof board 4, quickly extinguishing the flame on the fireproof board 4 and preventing the flame on the fireproof board 4 from spreading to other fireproof boards 4;

[0043] After the flame is extinguished, the staff replaces the damaged fireproof board 4. The staff squeezes the two support plates 44, causing the support plates 44 to drive the mounting rod 48 to move inward along the positioning block 47 and compressing the second spring 46 at the same time. The support plates 44 moving inward drive the clamping column 45 to move inward and separate from the limiting frame 43. Losing the restriction of the clamping column 45, the bottom plate 33 rotates downward. After the bottom plate 33 rotates downward, the expanded thermally expandable microspheres inside the support box 23 fall off. After the expanded thermally expandable microspheres fall off, the acting force of the first spring 41 causes the heat-conducting plate 40 to drive the heat-conducting rod 39 to move inward. The heat-conducting rod 39 moving inward drives the cover plate 12 to move inward, and the cover plate 12 moving inward drives the first plug 30 to move inward and enter the inside of the gas transmission pipe 29. The first plug 30 and the second magnet 38 move inward inside the gas transmission pipe 29. The second magnet 38 moving inward gradually approaches the blocking block 50, which causes the first magnet 34 on the blocking block 50 to adsorb the second magnet 38. The magnetic force causes the blocking block 50 longitudinally placed inside the gas transmission pipe 29 to rotate. The blocking block 50 rotating drives the connecting rod 35 to rotate, and the connecting rod 35 rotating causes the clockwork spring 37 to wind up. After the blocking block 50 rotates, it is horizontally placed inside the gas transmission pipe 29 again to block the gas transmission pipe 29, preventing the high-pressure carbon dioxide inside the support pipe 11 from leaking continuously;

[0044] In addition, the staff will take out the plug 2 42 from the feed port on the support box 23 and pour new heat-expandable microspheres into the support box 23 through the feed port to facilitate subsequent use, thereby achieving the thermal insulation and fire prevention effect on the wall 1 and improving the safety of the green building.

[0045] An installation groove 25 is opened on the left side of the fireproof board 4, and the interior of the installation groove 25 is filled with a foam layer 26 for blocking flames. The foam layer 26 is specifically an expandable foam material. A fireproof decorative panel 27 is fixedly sleeved inside the installation groove 25. The fireproof decorative panel 27 can protect the foam layer 26. The color of the fireproof decorative panel 27 is consistent with the surface color of the fireproof board 4.

[0046] Specifically, by setting up the fireproof board 4, when the surface of the fireproof board 4 catches fire, the foaming layer 26 inside the installation groove 25 quickly foams and expands, and the foaming and expansion of the foaming layer 26 drives the fireproof decorative board 27 to move outward. The foaming layer 26 and the fireproof decorative board 27 move outward and are higher than the surface of the fireproof board 4. This allows the foaming layer 26 and the fireproof decorative board 27 to form an isolation zone, preventing the flame on a single fireproof board 4 from spreading to other locations, thereby achieving the effect of isolating the flame.

[0047] A plurality of clamps 13 are embedded in the left side of the concrete layer 8, and the outer circumferential wall of the support tube 11 is movably connected with the inner circumferential wall of the clamp 13. A clamp 2 14 is arranged on the left side of the clamp 13, and the clamps 1 13 and 14 are fastened together by bolts. The staff places the clamp 2 14 on one side of the clamp 13 and then fixes the clamps 1 13 and 14 together with bolts, thereby fastening the support tube 11 with the clamps 13 and 14.

[0048] Specifically, by setting up the support tube 11, when laying the support tube 11, the staff places the support tube 11 inside the clamp 13, and the staff places the clamp 2 14 on one side of the clamp 13, and then the staff uses bolts to fix the clamp 13 and the clamp 2 14 together, thereby using the clamp 13 and the clamp 2 14 to lock the support tube 11 to prevent the support tube 11 from shaking.

[0049] A positioning rod 18 is fixedly installed on the left side of the concrete layer 8, and a ball head 19 is fixedly installed on the left end of the positioning rod 18. A connecting tube 20 is rotatably connected to the outer circumferential wall of the ball head 19, and a connecting ring 21 is fixedly sleeved on the outer circumferential wall of the connecting tube 20. The connecting ring 21 is connected to the right side of the fireproof board 4 through bolts. The outer circumferential wall of the connecting tube 20 is provided with threads, and a nut 22 is threadedly connected to the outer circumferential wall of the connecting tube 20. The right end of the connecting tube 20 is inclined inwardly and provided with a plurality of grooves, so that the rotating nut 22 can make the connecting tube 20 fit the ball head 19 inwardly;

[0050] Among them, the staff uses bolts to fix the fireproof board 4 and the connecting ring 21 together. During the installation of the fireproof board 4, the angle of the fireproof board 4 is adjusted so that the connecting tube 20 moves slightly around the ball head 19, so as to maintain the installation accuracy of multiple fireproof boards 4 and finally use the nut 22 to lock the fireproof board 4.

[0051] Specifically, through the setting of the connecting ring 21, the staff uses bolts to fix the fireproof board 4 and the connecting ring 21. During the installation of the fireproof board 4, the staff can adjust the angles of the four corners of the fireproof board 4 to maintain the installation accuracy of the multiple fireproof boards 4 and avoid unevenness between the multiple fireproof boards 4. The staff turns the nut 22 so that the nut 22 rotates along the connecting tube 20, which makes the right end of the connecting tube 20 fit on the ball head 19, thereby locking the position of the fireproof board 4.

[0052] A plurality of hooks 15 are pre-buried on the left side of the concrete layer 8, and two connecting ropes 17 are fixedly installed on the right side of the fireproof board 4. A support ring 16 is fixedly installed on one end of the connecting rope 17, and the support ring 16 is slidably connected to the hook 15. After installing the fireproof board 4, the staff hangs the support ring 16 on the hook 15, and the hook 15, the support ring 16 and the connecting rope 17 can be used as a safety rope for the fireproof board 4.

[0053] Specifically, by setting up the fireproof board 4, after installing the fireproof board 4, the staff hangs the support ring 16 on the hook 15, and the hook 15, the support ring 16 and the connecting rope 17 can be used as a safety rope of the fireproof board 4 to prevent the fireproof board 4 from falling and improve the safety of the fireproof board 4.

[0054] A plurality of stirrups 9 are arranged inside the wall 1 , and a plurality of steel bars 10 are arranged inside the wall 1 . The stirrups 9 are tied together by wire tying, and the stirrups 9 and the steel bars 10 cooperate to reinforce the wall 1 .

[0055] Specifically, through the setting of the wall 1, during the process of pouring the wall 1, the workers use wire to tie the stirrups 9 and the steel bars 10 together, and then the carpenters make molds on the outside of the stirrups 9 and the steel bars 10 and pour concrete to build the wall 1. The stirrups 9 and the steel bars 10 can support the wall 1 and improve the stability of the wall 1.

[0056] A plurality of brackets 5 are pre-buried on the left side of the wall 1 , and every four brackets 5 cooperate with the insulation board 2 . Rivets 6 for anchoring the insulation board 2 to the wall 1 are installed on the top surface of the brackets 5 .

[0057] Specifically, by setting up the insulation board 2, when multiple insulation boards 2 are installed on one side of the wall 1, the staff places the insulation board 2 inside the multiple brackets 5, and then the staff uses rivets 6 to anchor the insulation board 2 to further prevent the insulation board 2 from falling off the wall 1.

[0058] As a preferred implementation mode in this embodiment, please refer to Figures 1 to 11 , and the construction method is as follows:

[0059] I. Prepare materials such as insulation board 2 (foam concrete fireproof insulation board), protective net 7, fireproof board 4, support pipe 11, gas transmission pipe 29, thermally expandable microspheres, high-pressure carbon dioxide gas cylinders, sealing frame 49, fireproof decorative board 27, etc.; prepare construction tools such as concrete pouring equipment, bolts, clamps, rivets 6, binding wires, carpentry molds, etc.;

[0060] II. Clean the surface of wall 1 to ensure that wall 1 is flat, dry, and free of impurities such as oil stains and floating dust. Embed bracket 5 on one side of wall 1 for fixing insulation board 2;

[0061] III. Install foam concrete fireproof insulation board 2 on one side of wall 1 to ensure that insulation board 2 is closely attached to wall 1. Hang protective net 7 on one side of insulation board 2 to increase the adhesion between insulation board 2 and concrete. Use a carpentry mold to pour concrete layer 8 on one side of protective net 7, sandwich insulation board 2 between wall 1 and concrete layer 8, ensure uniform concrete pouring, avoid voids or cracks, and at the same time ensure that insulation board 2 is completely wrapped by concrete to improve fireproof performance;

[0062] IV. Fix and install positioning rod 18 on one side of concrete layer 8. Install ball head 19 at one end of positioning rod 18, sleeved connecting cylinder 20 on ball head 19. Fix and sleeve connecting ring 21 on the outer circumferential wall surface of connecting cylinder 20. Connecting ring is connected to fireproof board 4 through bolts. Fireproof board 4 is fixed on concrete layer 8 through rivets 6. Adjust the angle of fireproof board 4 to make connecting cylinder 20 move slightly around ball head 19 to ensure that multiple fireproof boards 4 are installed flat. Finally, lock the position of fireproof board 4 with nut 22;

[0063] V. Embed clamp one 13 on one side of concrete layer 8, place support pipe 11 inside clamp one 13, place clamp two 14 on one side of clamp one 13, and fix clamp one 13 and clamp two 14 together with bolts to lock support pipe 11 to prevent it from shaking;

[0064] VI. A circular metal cover plate 12 is movably sleeved on one side of the fireproof board 4. A number of guide frames 28 are fixedly installed on one side of the cover plate 12 for guiding the direction of carbon dioxide ejection. A plug 30 is fixedly installed on one side of the cover plate 12 for blocking the gas delivery pipe 29. A fixed box 36 is installed on the outer wall surface of the gas delivery pipe 29, and a blocking block 50 and a spring 37 are installed inside. The blocking block is attracted to the magnet 38 on the plug 30 through the magnet 34 to realize the automatic blocking and reset functions of the gas delivery pipe 29. A number of support boxes 23 are fixedly installed on one side of the concrete layer 8. The support boxes 23 are filled with thermally expandable microspheres, which are of medium-temperature expansion type with an expansion temperature of 110 - 160 °C.

[0065] VII. Conduct a functional test on the thermal insulation and fire protection mechanism 3, simulate a fire scenario, check whether the thermally expandable microspheres can expand normally, and whether the carbon dioxide can be ejected smoothly and cover the surface of the fireproof board 4 to ensure that the system can respond quickly and extinguish the flame.

[0066] Working principle: Through the provided wall 1, a number of thermal insulation boards 2 are installed on one side of the wall 1. The thermal insulation boards 2 are used to reduce the heat loss in the room and play a role in thermal insulation. A protective net 7 is hung on one side of the thermal insulation boards 2 to increase the adhesion between the thermal insulation boards 2 and the concrete. The concrete layer 8 is poured on one side of the protective net 7 using concrete and a woodworking mold, clamping the thermal insulation boards 2 between the wall 1 and the concrete layer 8 to prevent the thermal insulation boards 2 from falling off or being affected by the external environment;

[0067] Secondly, a number of fireproof boards 4 are installed on the outer side of the concrete layer 8. The fireproof boards 4 are used to further enhance the fireproof performance of the wall 1. Two support pipes 11 are installed on one side of the concrete layer 8. The support pipes 11 are used to store high-pressure carbon dioxide gas. Two gas delivery pipes 29 are fixedly installed on the outer wall surface of the support pipes 11. The gas delivery pipes 29 are used to transport the high-pressure carbon dioxide to the surface of the fireproof board 4;

[0068] Next, when a fire breaks out on the surface of the fireproof board 4, the heat of the flame is transferred to the thermally expandable microspheres in the support box 23 through the heat conduction rod 39 and the heat conduction plate 40. The thermally expandable microspheres expand due to heat, squeeze the heat conduction plate 40, and push the heat conduction rod 39 to move outward, thereby driving the cover plate 12 to move outward. When the cover plate 12 moves outward, the plug 30 moves outward accordingly, releasing the blockage of the gas delivery pipe 29;

[0069] The blocking block 50 in the gas delivery pipe 29 loses the abutment of the plug 30, the spring 37 releases its elastic force, drives the blocking block 50 to rotate, opens the gas delivery pipe 29, and the high-pressure carbon dioxide in the support pipe 11 is ejected through the gas delivery pipe 29, diffuses along the cover plate 12 and the guide frame 28 to the surface of the fireproof board 4, and quickly extinguishes the flame;

[0070] Meanwhile, the foaming layer 26 inside the fireproof board 4 expands rapidly, pushing the fireproof decorative board 27 to move outward and rise above the surface of the fireproof board 4. The foaming layer 26 and the fireproof decorative board 27 form an isolation zone to prevent the flame from spreading to other fireproof boards 4;

[0071] Finally, after the flame goes out, the staff squeezes the support plate 44 to separate the clamping post 45 from the limiting frame 43. The bottom plate 33 rotates downward to discharge the expanded thermal expansion microspheres. The acting force of the first spring 41 resets the heat conduction rod 39 and the heat conduction plate 40, driving the cover plate 12 and the first plug 30 to reset. The second magnet 38 on the first plug 30 attracts the first magnet 34 in the air duct 29, and the blocking block 50 rotates to re-block the air duct 29.

[0072] In addition, the staff removes the second plug 42 from the feed port on the support box 23 and adds new thermal expansion microspheres through the feed port for subsequent use, and replaces the damaged fireproof board 4 to ensure the integrity and reliability of the system.

[0073] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
