Concrete exterior wall refers to the building exterior wall that uses concrete materials as the main structure and enclosure components. It is formed by on-site casting or prefabricated assembly, and has good bearing capacity, durability and protective properties. Concrete exterior walls are widely used in various types of buildings and are one of the common exterior wall forms in modern buildings. Concrete exterior walls not only bear the structural load of the building, but also play a protective role, which can effectively resist the invasion of natural factors such as wind, rain and snow. Through reasonable design, concrete exterior walls can meet the building's insulation, heat insulation, waterproofing, fire prevention and other requirements. After searching, it is found that there are problems with the thermal insulation and fireproof structure of concrete exterior walls in the prior art.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A cover plate 12 is movably sleeved on one side of the fireproof board 4. The cover plate 12 is a metal circular structure with good thermal conductivity. A connecting hole 24 is opened on one side of the fireproof board 4. The outer circular wall surface of the cover plate 12 is movably sleeved with the inner circular wall surface of the connecting hole 24. A plurality of guide frames 28 are fixedly installed on the right side of the cover plate 12. A gas pipe 29 is fixedly installed on the outer circular wall surface of the support tube 11. The right side of the cover plate 12 is fixedly installed A plug 30 is provided for blocking the gas pipe 29. The outer circumferential wall of the plug 30 is movably connected to the inner circumferential wall of the gas 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 to a bottom plate 33 through a hinge. A heat conducting plate 40 is slidably connected inside the support box 23. A heat conducting rod 39 is fixedly installed on the left side of the heat conducting plate 40. The left end of the heat conducting rod 39 is fixedly connected to one side of the cover plate 12. Thermal expansion microspheres are filled between the heat conducting plate 40 and the support box 23. Among them, the heat-expandable microspheres are a type of heat-expandable microcapsules with a core-shell structure, which are composed of a thermoplastic polymer shell wrapping a low-boiling point solvent such as liquid alkane gas or other compounds. Their diameter is generally between 10-50 μm, and their volume can expand rapidly to dozens of times their own after heating. The heat-expandable microspheres filled inside the support box 23 are medium-temperature expansion type, and the specific expansion temperature is 110-160°C; the heat-expandable microspheres can be used to release carbon dioxide when the plug 30 is separated from the gas pipe 29.

[0017] The outer circumferential wall of the fireproof board 4 is fixedly sleeved with a sealing frame 49, which is a flame-retardant rubber structure. The sealing frame 49 allows multiple fireproof boards 4 to be tightly connected, reduces the influence of thermal expansion and contraction on the fireproof board 4, and reduces the gap between the multiple fireproof boards 4. The outer circumferential wall of the gas delivery pipe 29 is fixedly installed with a fixing box 36, and the inner circumferential wall of the gas delivery pipe 29 is rotatably connected with a blocking block 50. A magnet 1 34 is fixedly installed on the left side of the blocking block 50, and a magnet 2 38 is fixedly installed on the right side of the plug 1 30. The magnet 1 34 and the magnet 2 38 attract each other. The outer circumferential wall of the heat-conducting rod 39 is sleeved with a spring 1 41 for resetting the heat-conducting rod 39 and the heat-conducting plate 40. The inner top surface of the fixed box 36 is rotatably connected to a connecting rod 35 through a bearing, the bottom surface of the connecting rod 35 is fixedly connected to the outer circumferential wall surface of the blocking block 50, a spring 37 is wound around the outer circumferential wall surface of the connecting rod 35, one side of the spring 37 is fixedly connected to the inner circumferential wall surface of the fixed box 36, and the spring 37 provides the blocking block 50 with the force required for rotation, the inner part of the guide frame 28 is rotatably connected to a supporting roller 31 through a bearing, and a plurality of movable plates 32 are fixedly installed on the outer circumferential wall surface of the supporting roller 31, and the supporting roller 31 and the movable plate 32 rotate to guide and transport carbon dioxide; When a flame burns on the surface of the fireproof board 4, the heat-expandable microspheres inside the support box 23 will expand due to the temperature of the flame, and the expansion of the heat-expandable microspheres will drive the heat-conducting rod 39 and the cover plate 12 to move outward. The cover plate 12 moves outward so that the high-pressure carbon dioxide inside the support tube 11 is ejected through the gas pipe 29. The ejected carbon dioxide is blocked by the cover plate 12 and diffuses outward along the surface of the fireproof board 4 through multiple guide frames 28. The outward diffusion of carbon dioxide quickly extinguishes the flame on the surface of the fireproof board 4. The top surface of the support box 23 is movably sleeved with a plug 2 42, a feed port is provided on the top surface of the support box 23, the outer circumferential wall surface of the plug 2 42 is movably sleeved with the inner circumferential wall surface of the feed port, the left and right sides of the bottom plate 33 are fixedly mounted with limiting frames 43, the top surface of the support box 23 is fixedly mounted with two positioning blocks 47, the positioning blocks 47 are elastically connected with a support plate 44 through a spring 2 46, a clamping column 45 is fixedly mounted on the side of the support plate 44, the clamping column 45 is movably clamped with the limiting frame 43, the spring 2 46 is sleeved on the outer circumferential wall surface of the mounting rod 48, one end of the spring 2 46 is fixedly connected to one side of the support plate 44, and the other end of the spring 2 46 is fixedly connected to one side of the positioning block 47; Accordingly, 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 supporting plate 44, so that the bottom plate 33 rotates downward, and the bottom plate 33 rotates downward so that the expanded heat-expandable microspheres in the supporting box 23 fall off. At this time, the force of the spring 1 41 causes the heat-conducting rod 39 and the heat-conducting plate 40 to drive the cover plate 12 to reset, and then the staff resets the bottom plate 33 and adds new heat-expandable microspheres to the supporting box 23 through the feed port; The cover plate 12 is reset to drive the plug 30 to move backward into the interior of the gas pipe 29. At this time, the magnet 34 on the gas pipe 29 will attract the magnet 38 on the plug 30 due to magnetic force, which makes the blocking block 50 rotate 90 degrees and lie horizontally in the heat conducting rod 39, thereby blocking the support tube 11 again.

[0018] Through the above technical features, through the setting of the insulation board 2, multiple insulation boards 2 are installed on one side of the wall 1, the insulation board 2 can reduce the loss of indoor heat, and the protective net 7 is hung on one side of the insulation board 2 to increase the adhesion between the insulation board 2 and the concrete. Then the staff uses concrete and woodworking molds to cast a concrete layer 8 on one side of the protective net 7. The wall 1 and the concrete layer 8 sandwich the insulation board 2 in the middle to avoid the insulation board 2 from falling off, cracking and other problems, while reducing the impact of the external environment on the insulation board 2. In addition, the insulation board 2 is wrapped by concrete, which can effectively block the fire source and reduce the risk of fire; The multiple fireproof panels 4 on the side of the concrete layer 8 further improve the fireproof performance. The staff will use the flange to connect the high-pressure carbon dioxide gas to the interior of the support pipe 11. When the surface of the fireproof panel 4 catches fire, the heat of the flame will be transferred to the heat-expanding microspheres inside the support box 23 through the cover plate 12, the heat-conducting rod 39 and the heat-conducting plate 40. The heat-expanding microspheres will squeeze the heat-conducting plate 40 when heated. The heat-conducting plate 40 is squeezed and drives the heat-conducting rod 39 to move outward, and at the same time, the spring 41 is compressed. The heat-conducting rod 39 moves outward and drives the cover plate 12 to move outward. The cover plate 12 moves outward and drives the plug 30 to move outward. After the plug 30 moves outward, the blocking block 50 loses the abutment of the plug 30, which releases the clockwork 37 and causes the connecting rod 35 to drive the blocking block 50 to rotate ninety degrees. , the blocking block 50 rotates 90 degrees so that the blocking block 50 originally placed horizontally inside the gas pipe 29 is located vertically inside the gas pipe 29, and the obstruction of the plug 30 and the blocking block 50 is lost. The high-pressure carbon dioxide gas inside the support tube 11 is ejected through the gas pipe 29, and the carbon dioxide is sprayed onto the cover plate 12 along the gas pipe 29. Due to the obstruction of the cover plate 12, part of the carbon dioxide enters the inside of the guide frame 28, and the carbon dioxide entering the inside of the guide frame 28 moves forward to drive the movable plate 32 and the support roller 31 to rotate. The support roller 31 and the movable plate 32 rotate to guide the carbon dioxide and transport the carbon dioxide forward, which makes the carbon dioxide move along the surface of the fireproof board 4, thereby 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; When the flame is extinguished, the staff replaces the damaged fireproof board 4. The staff squeezes the two support plates 44 so that the support plates 44 drive the mounting rod 48 to move inward along the positioning block 47 and compresses the spring 2 46. The support plates 44 move inward and drive the clamping column 45 to move inward and separate from the limiting frame 43. Without the restriction of the clamping column 45, the bottom plate 33 rotates downward. After the bottom plate 33 rotates downward, the expanded thermal expansion microspheres inside the support box 23 fall off. After the expanded thermal expansion microspheres fall off, the force of the spring 1 41 causes the heat conducting plate 40 to drive the heat conducting rod 39 to move inward. The heat conducting rod 39 moves inward and drives the cover plate 12 Move inwards, the cover plate 12 moves inwards to drive the plug 1 30 to move inwards and enter the interior of the gas pipe 29, the plug 1 30 and the magnet 2 38 move inwards inside the gas pipe 29, the magnet 2 38 moves inwards and gradually approaches the blocking block 50, which makes the magnet 1 34 on the blocking block 50 attract the magnet 2 38, and the magnetic force makes the blocking block 50 inside the gas pipe 29 rotate longitudinally, the blocking block 50 rotates to drive the connecting rod 35 to rotate, the connecting rod 35 rotates to wind up the spring 37, and the blocking block 50 rotates and is again placed horizontally inside the gas pipe 29 to block the gas pipe 29, so as to prevent the high-pressure carbon dioxide inside the support pipe 11 from continuing to leak; 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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; 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0028] 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.

[0030] 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.

[0031] As a preferred implementation in this embodiment, please refer to Figures 1 to 11 The construction methods are as follows: 1. Prepare materials such as insulation board 2 (foam concrete fireproof insulation board), protective net 7, fireproof board 4, support pipe 11, gas pipe 29, thermal expansion microspheres, high-pressure carbon dioxide cylinders, sealing frame 49, fireproof decorative board 27, etc.; prepare construction tools such as concrete pouring equipment, bolts, clamps, rivets 6, wire ties, woodworking molds, etc.; 2. Clean the surface of the wall 1 to ensure that the wall 1 is flat, dry, and free of impurities such as oil, dust, etc., and embed a bracket 5 on one side of the wall 1 to fix the insulation board 2; 3. Install the foam concrete fireproof insulation board 2 on one side of the wall 1 to ensure that the insulation board 2 fits tightly with the wall 1, hang a protective net 7 on one side of the insulation board 2 to increase the adhesion between the insulation board 2 and the concrete, use a woodworking mold to pour a concrete layer 8 on one side of the protective net 7, and clamp the insulation board 2 between the wall 1 and the concrete layer 8 to ensure that the concrete is poured evenly to avoid voids or cracks, and at the same time ensure that the insulation board 2 is completely wrapped by the concrete to improve the fireproof performance; Fourth, a positioning rod 18 is fixedly installed on one side of the concrete layer 8, a ball head 19 is installed at one end of the positioning rod 18, a connecting tube 20 is sleeved on the ball head 19, a connecting ring 21 is fixedly sleeved on the outer wall of the connecting tube 20, the connecting ring is connected to the fireproof board 4 by bolts, the fireproof board 4 is fixed to the concrete layer 8 by rivets 6, the angle of the fireproof board 4 is adjusted, and the connecting tube 20 is slightly moved around the ball head 19 to ensure that multiple fireproof boards 4 are installed flat, and finally the position of the fireproof board 4 is locked by nuts 22; 5. Pre-embed the clamp 13 on one side of the concrete layer 8, place the support tube 11 inside the clamp 13, place the clamp 2 14 on one side of the clamp 13, and use bolts to fix the clamp 13 and the clamp 2 14 together to lock the support tube 11 to prevent it from shaking; 6. A metal circular cover plate 12 is movably sleeved on one side of the fireproof board 4. A plurality of guide frames 28 are fixedly installed on one side of the cover plate 12 to guide the direction of carbon dioxide spraying. A plug 30 is fixedly installed on one side of the cover plate 12 to block the gas pipe 29. A fixed box 36 is installed on the outer circular wall of the gas pipe 29. A blocking block 50 and a spring 37 are installed inside. The blocking block attracts the magnet 34 and the magnet 38 on the plug 30 to realize the automatic blocking and resetting function of the gas pipe 29. A plurality of support boxes 23 are fixedly installed on one side of the concrete layer 8. The support box 23 is filled with thermal expansion microspheres. The thermal expansion microspheres are medium-temperature expansion type with an expansion temperature of 110-160°C.

[0032] 7. Perform functional tests on the thermal insulation and fire protection mechanism 3, simulate fire scenes, check whether the heat-expandable microspheres can expand normally, whether the carbon dioxide can be smoothly sprayed out and cover the surface of the fire protection board 4, and ensure that the system can respond quickly and extinguish the flame.

[0033] Working principle: through the wall 1, a plurality of insulation boards 2 are installed on one side of the wall 1. The insulation boards 2 are used to reduce indoor heat loss and play a role in heat preservation. A protective net 7 is hung on one side of the insulation board 2 to increase the adhesion between the insulation board 2 and the concrete. A concrete layer 8 is poured on one side of the protective net 7 using concrete and a woodworking mold. The insulation board 2 is sandwiched between the wall 1 and the concrete layer 8 to prevent the insulation board 2 from falling off or being affected by the external environment. Secondly, a plurality of fireproof panels 4 are installed on the outside of the concrete layer 8, and the fireproof panels 4 are used to further improve the fireproof performance of the wall 1. Two support pipes 11 are installed on one side of the concrete layer 8, and the support pipes 11 are used to store high-pressure carbon dioxide gas. Two gas pipes 29 are fixedly installed on the outer circular wall of the support pipe 11, and the gas pipes 29 are used to transport high-pressure carbon dioxide to the surface of the fireproof panels 4; Next, when the surface of the fireproof board 4 is on fire, the heat of the flame is transferred to the heat-expanding microspheres in the support box 23 through the heat-conducting rod 39 and the heat-conducting plate 40. The heat-expanding microspheres expand due to the heat, squeeze the heat-conducting plate 40, push the heat-conducting rod 39 to move outward, and then drive the cover plate 12 to move outward. When the cover plate 12 moves outward, the plug 1 30 moves outward accordingly, releasing the blockage of the gas pipe 29. The blocking block 50 in the gas pipe 29 loses the contact with the plug 1 30, and the spring 37 releases the elastic force, driving the blocking block 50 to rotate, opening the gas pipe 29, and the high-pressure carbon dioxide in the support pipe 11 is ejected through the gas 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; At the same time, the foam layer 26 inside the fireproof board 4 expands rapidly, pushing the fireproof decorative board 27 to move outward, higher than the surface of the fireproof board 4, and the foam layer 26 and the fireproof decorative board 27 form an isolation zone to prevent the flame from spreading to other fireproof boards 4; Finally, after the flame is extinguished, the staff squeezes the support plate 44 to separate the clamping column 45 from the limiting frame 43, and the bottom plate 33 rotates downward to discharge the expanded thermal expansion microspheres. The force of the spring 41 resets the heat-conducting rod 39 and the heat-conducting plate 40, driving the cover plate 12 and the plug 30 to reset. The magnet 38 on the plug 30 and the magnet 34 in the gas pipe 29 attract each other, and the blocking block 50 rotates to re-block the gas pipe 29.

[0034] In addition, the staff takes out the plug 2 42 from the feed port on the support box 23 and adds new heat-expandable microspheres through the feed port for subsequent use to replace the damaged fireproof board 4 to ensure the integrity and reliability of the system.

[0035] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
