DETAILED DESCRIPTION

[0036] 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. Embodiment 1

[0037] An external wall insulation structure for old building reconstruction mainly comprises the following steps: S1, checking the base layer;

[0038] 1. Understand the wall materials used on the construction base;

[0039] 2. Understand the design strength grade of the original plastering mortar and whether the plastering is hung with steel wire mesh;

[0040] 3. Check the flatness of the base surface, the straightness of the corners, whether the wall has hollows or cracks, and keep records.

[0041] 4. Check whether the setback spacing around the door and window openings meets the distance of the thermal insulation decorative integrated panel, whether the side margins of the four side window corners are equal, and whether the door and window frames are vertical.

[0042] S2. Grid division and marking lines: Carefully study the grid division drawings and strictly mark the lines according to the grid division drawings. The horizontal lines should be determined with a level tube and the vertical lines should be calibrated with a plumb line. The grid division joints of all plates should be uniform, and the horizontal and vertical lines cannot be calculated after being determined in one position. They must be recalibrated after a certain distance.

[0043] S3. Install the keel base and keel; after marking the dividing lines and checking for errors, use a manual cutting machine to cut the base insulation to the size of the keel base at the floor slab of each floor, drill the embedded holes of the keel base according to the marked dividing lines, and the depth of the embedded holes must meet the design requirements. After the keel base is installed, install the thermal insulation and decorative integrated keel on the keel base. The adjacent panels of the vertical keel need to be staggered. After the keel is installed, use a hollow drill to drill holes at the staggered joints of the keel layout. The holes must not deviate from the T-shaped staggered joints, and then calibrate the flatness of the keel.

[0044] S4. Install the thermal insulation decorative integrated panels. The thermal insulation decorative integrated panels are cut according to the staggered size. The general size is 1200mm long and 600mm wide. Install the thermal insulation decorative integrated panels from left to right. Use special U-shaped telescopic hangers to fix the thermal insulation decorative integrated panel hangers on the keel. Control the flatness during installation. If there are uneven areas, use U-shaped telescopic connectors to adjust the flatness. After two layers of thermal insulation decorative integrated panels are installed, proceed to the next step.

[0045] S5. Fill with foam strips. After a vertical construction surface is installed, fill the horizontal and vertical partition joints with foam strips. The foam strips should be filled densely to prevent grout leakage. After all the foam strips are filled, use a ruler to check the horizontal and vertical flatness.

[0046] S6. Pour liquid or foaming materials on site. After the thermal insulation decorative integrated board is installed, use an air pump to blow away the dust in the cavity. Then you can pour bonding mortar, foamed cement slurry, polyurethane foam, polystyrene particle slurry, glass bead slurry, microporous plasticized slurry and other slurry materials between the thermal insulation decorative integrated board and the wall. Pour the slurry in layers and do not pour too much. After pouring, wait until the slurry flows into all the gaps and foams, then pour the last layer. After all the pouring is completed, the thermal insulation decorative integrated board and the base wall are bonded together.

[0047] S7. Fill with elastic sealant. When filling with elastic sealant, masking tape should be pasted on both sides. When pasting, the vertical, horizontal and width should be equal. The seam width should be uniform and meet the design requirements. The sealant should be filled densely. The partition seams after forming should naturally form a smooth arc. The intersection of vertical and horizontal partition seams should form an inner eight-character shape with clear angles.

[0048] S8. Remove the protective film. It is strictly forbidden to remove the protective film before all processes are completed. If the protective film is found to be loose during construction, it must be taped in time. All processes must be completed before the protective film can be removed, and it can be removed only with the consent of the on-site management personnel. After the protective film is removed, the board surface must be cleaned and the finished products must be taken care of. After all work surfaces are completed, they must be reported to the construction party for completion acceptance.

[0049] S9. Clean the board surface.

[0050] S10. Acceptance.

[0051] Safety performance of thermal insulation system:

[0052] 1. The U-shaped hangers used in the integrated system of pouring thermal insulation and decoration allow each panel to release the necessary stress like fish scales, avoiding cracking, leakage, and falling off caused by the shrinkage and expansion changes of the decorative panels due to heat and cold.

[0053] 2. Keel: A keel base is set on each floor, and the keel base is fixed directly on the floor slab. Then the horizontal and vertical keels are fixed with screws, and the keels are poured together into the integrated decoration and thermal insulation system. Even without the bonding of slurry, the panel will not fall off.

[0054] 3. Board grooving: dovetail grooves are made on the inner side of the thermal insulation decorative panel and on both sides of the thermal insulation board. After pouring, the contact surfaces are connected to form a whole, making the integrity more solid.

[0055] 4. Drilling. Currently, all conventional system insulation boards usually fall off by cracking from the four corners. Drill holes at the staggered joints of each layer of decorative insulation board, and use expansion bolts to fix a T-shaped hanger to the main base at the drilled holes. This solves the warping, cracking and falling of the decorative panel. Then, pour the slurry to bond the panel to the base to form a whole.

[0056] 5. Overall safety: On-site cast-in-place thermal insulation and decorative integrated panels, combined with U-shaped hangers and drilled bonding columns, make the original insulation and base layer more solid, solve the weather resistance of the thermal insulation and decorative integrated panels to hot and cold changes, and extend the life of the exterior wall to the same life as the building.

[0057] Advantages of the insulation system: The insulation decorative integrated board can choose various surface materials, various insulation materials and aluminum veneer and other decorative integrated boards. There is no need to remove the original insulation material. A layer of decorative integrated board can be added on the original insulation material, which can achieve the current 75% energy saving standard. The energy saving of the insulation decorative integrated board is even lower when it is thickened. After the insulation decorative integrated board and the base cavity are poured with slurry, the slurry can be poured into the gap and the slurry can be foamed. The insulation decorative integrated board is more densely bonded to the base, with a bonding rate of 100%, which increases the integrity of the exterior wall. After the original insulation has been in service for 25 years, if the exterior wall insulation is removed, the mortar and broken insulation materials are easily volatilized into the air at high altitude, seriously polluting the air. Removal There is adhesive mortar on the insulation, and recycling and destruction will cause a great waste of resources. The use of cast insulation decoration integrated board system allows the original insulation to continue to insulate, reducing the waste of raw materials and the labor cost of removing the original insulation, which can greatly reduce environmental protection. The original conventional pasting thin plaster system, the insulation layer and the base layer adopt the frame point bonding method, forming a chimney effect. Once the external wall insulation catches fire, the oxygen inside and outside the insulation will quickly assist combustion. The cast insulation decoration integrated board system is used to make the slurry bond the insulation decoration integrated board with the original insulation and the base wall. The cast insulation decoration integrated board system has no cavity, and the slurry can both insulate and waterproof, thus blocking the fire source. It also plays a waterproof role in the external wall, achieving three goals at one stroke. Embodiment 2

[0058] like Figure 1-5 As shown, an external wall insulation structure for the reconstruction of old buildings comprises an old building 1, wherein the old building 1 is a wall body which is damaged due to long-term use, and a pouring layer 2 is provided on one side of the old building 1, wherein the pouring layer 2 is directly poured after complete assembly, wherein the pouring layer 2 is a slurry, such as bonding mortar slurry, foamed cement slurry, polyurethane foam, polystyrene particle slurry, glass bead slurry, microporous plasticized slurry, which can not only improve the strength of the old building 1 and prevent it from further damage, but also further enhance the insulation effect.

[0059] A plurality of groups of plug holes 13 are evenly arrayed inside the old building 1, and a plurality of groups of fixing holes 14 are evenly arrayed inside the casting layer 2 and at positions corresponding to the plug holes 13. A fixing rod 5 is arranged inside the plug hole 13, and the other end of the fixing rod 5 passes through the casting layer 2 along the fixing hole 14. The fixing rod 5 is used to fix the old building 1 and the casting layer 2. The fixing rod 5 is often made of a material with good pressure resistance and will not chemically react with the old building 1 and the casting layer 2. A metal rod is commonly used inside, and a circle of plastic sleeve is arranged on the outer surface of the metal rod. Such a design can meet the above requirements, and a snap-fit ​​mechanism 18 is arranged on the other side of the fixing rod 5.

[0060] The clamping mechanism 18 includes a transverse U-shaped block 7, a first connecting groove is provided inside the transverse U-shaped block 7, a longitudinal U-shaped block 8 is provided in the central vertical direction of the transverse U-shaped block 7, a second connecting groove is provided in the longitudinal U-shaped block 8, a transverse keel 3 is provided inside the first connecting groove, a longitudinal keel 4 is provided inside the second connecting groove, and the transverse U-shaped block 7 is connected to the longitudinal U-shaped block 8 at the center position, so the transverse U-shaped block 7 and the longitudinal U-shaped block 8 form a complete cross-shaped structure, and the middle part is a U-shaped structure. This design not only makes the transverse U-shaped block 7 and the longitudinal U-shaped block 8 more assembly performance, but also And it has a certain anti-seismic buffer effect, improves its durability and deformability, the transverse keel 3 is located inside the transverse U-shaped block 7, and the longitudinal keel 4 is located inside the longitudinal U-shaped block 8, then the transverse U-shaped block 7 and the longitudinal U-shaped block 8 can limit the position of the transverse keel 3 and the longitudinal keel 4. With the help of this limitation, not only the compactness and wrapping during assembly construction can be guaranteed, and the strength of the transverse keel 3 and the longitudinal keel 4 can be improved, but also the transverse U-shaped block 7 and the longitudinal U-shaped block 8 can be effectively reacted to avoid damage to their structure caused by long-term bending and deformation.

[0061] A plurality of groups of rear baffles 9 are arranged in a circular array on the side of the transverse U-shaped block 7 and the longitudinal U-shaped block 8 away from the casting layer 2, a front baffle 10 is arranged on the side of the rear baffle 9 away from the casting layer 2, a snap-in groove 11 is arranged between the front baffle 10 and the rear baffle 9, a thermal insulation decorative integrated panel 12 is snapped into the inside of the snap-in groove 11, and the thermal insulation decorative integrated panel 12 can be used to decorate and protect the outer side of the casting layer 2, thereby improving the aesthetics and adaptability of the wall and increasing the service life. At the same time, the setting of the snap-in groove 11 can ensure the stability of the insertion of the thermal insulation decorative integrated panel 12 and improve the assembly efficiency.

[0062] A transverse foam strip 15 is provided between two adjacent thermal insulation and decorative integrated panels 12 in the vertical direction, and a longitudinal foam strip 16 is provided between two adjacent thermal insulation and decorative integrated panels 12 in the horizontal direction. Because the interior of the transverse U-shaped block 7 and the longitudinal U-shaped block 8 is a slotted structure, and the transverse keel 3 and the longitudinal keel 4 are loaded inside, and the thermal insulation and decorative integrated panel 12 is located inside the clamping groove 11, and is mainly distributed on the outer surface of the transverse U-shaped block 7 and the longitudinal U-shaped block 8.

[0063] Multiple groups of transverse foam strips 15 are parallel to the transverse keel 3, and multiple groups of longitudinal foam strips 16 are parallel to the longitudinal keel 4. The transverse foam strips 15 and the longitudinal foam strips 16 are located between adjacent thermal insulation and decorative integrated panels 12. In particular, the transverse foam strips 15 and the longitudinal foam strips 16 are not located inside the transverse U-shaped block 7 and the longitudinal U-shaped block 8. In this way, the transverse foam strips 15 and the longitudinal foam strips 16 can be effectively prevented from hindering the elastic changes of the transverse U-shaped block 7 and the longitudinal U-shaped block 8, thereby reducing their elastic performance.

[0064] A buckle cover 17 is provided at the intersection of the transverse U-shaped block 7 and the longitudinal U-shaped block 8, and the buckle cover 17 is clamped with multiple groups of front baffles 10. The buckle cover 17 can be used to fix and protect the intersection of the transverse U-shaped block 7 and the longitudinal U-shaped block 8 to avoid damage at the intersection. In particular, a gap for the buckle cover 17 can be left at the intersection of the transverse U-shaped block 7 and the longitudinal U-shaped block 8, and then the buckle cover 17 can be directly fixed at the intersection to achieve the desired fixed clamping effect.

[0065] Both the transverse U-shaped block 7 and the longitudinal U-shaped block 8 are made of elastic materials, such as stainless steel plates or aluminum. The transverse U-shaped block 7 and the longitudinal U-shaped block 8 can be deformed in any direction. In this way, even if the thermal insulation decorative integrated panel 12 is squeezed to one side due to thermal expansion and contraction during long-term use, the squeezing can be buffered by its own elasticity, thereby improving its durability. In addition, when the thermal insulation decorative integrated panel 12 is subjected to external impact, the impact force can be damped and buffered to a certain extent by the support of the adjacent multiple rear baffles 9 and the elastic deformation ability of the transverse U-shaped block 7 and the longitudinal U-shaped block 8, thereby protecting the internal casting layer 2.

[0066] The thermal insulation decorative integrated panel 12 is provided with a pattern on the side away from the casting layer 2, and the patterns of the transverse foam strips 15 and the longitudinal foam strips 16 on the side away from the casting layer 2 match the pattern of the thermal insulation decorative integrated panel 12. With the joint action of the thermal insulation decorative integrated panel 12, the transverse foam strips 15 and the longitudinal foam strips 16, the exterior wall can present a complete pattern, thereby improving the aesthetics of the wall.

[0067] The height of the rear baffle 9 is greater than that of the front baffle 10, and the width of the thermal insulation and decorative integrated panel 12 is less than the width of the snap-in groove 11. In this way, when it rains or is sprinkled with water, water will gather inside the snap-in groove 11 along the rear baffle 9, and ensure that when the water level rises, it can directly flow out along the front baffle 10, thereby ensuring the dryness of the internal casting layer 2. At the same time, the snap-in grooves 11 are all inclined downward from the end of the longitudinal keel 4 to the other end. The advantage of this design is that the residual water inside the snap-in groove 11 can be effectively discharged directly along the snap-in groove 11 to the outside, avoiding long-term accumulation of water and causing damage to the internal thermal insulation and decorative integrated panel 12.

[0068] Four groups of rear baffles 9 are provided at the intersection of the transverse keel 3 and the longitudinal keel 4. The rear baffles 9 are located in four directions of the intersection. The transverse keel 3 and the longitudinal keel 4 are fixed by welding or bolts. Through the design of four groups of rear baffles 9 and front baffles 10, the comprehensive plug-in assembly of the wall can be effectively realized. The transverse keel 3 and the longitudinal keel 4 at the intersection are fixed by winding steel wire, which can effectively improve their fixing performance and ensure that they have good durability and stability.

[0069] The front and back sides of the four corners of the thermal insulation decorative integrated panel 12 are provided with card slots, and the card slots are matched with the front baffle 10 and the rear baffle 9. The card slots can not only improve the card connection and fixing effect between the thermal insulation decorative integrated panel 12 and the card slot 11, but also ensure that the side of the thermal insulation decorative integrated panel 12 away from the old building 1 is a complete and smooth plane, thereby improving the thermal insulation effect and improving the aesthetics and comfort.

[0070] During use, when the old building 1 cracks and its performance deteriorates, a plurality of groups of plug holes 13 are evenly arrayed on the outside of the old building 1, and the fixing rod 5 is inserted into the plug hole 13, and then the transverse keel 3 and the longitudinal keel 4 are inserted and fixed between the first connecting groove and the second connecting groove on the inner side of the transverse U-shaped block 7 and the longitudinal U-shaped block 8 at the other end of the fixing rod 5, and the thermal insulation decorative integrated panel 12 is inserted into the adjacent plurality of clamping grooves 11. The thermal insulation decorative integrated panel 12 is plugged and fixed according to a certain graphic shape, so that the wall surface has a certain aesthetic performance.

[0071] Afterwards, transverse foam strips 15 and longitudinal foam strips 16 are inserted in the gaps between adjacent thermal insulation decorative integrated panels 12, and buckle covers 17 are snapped in at the junction of the transverse U-shaped block 7 and the longitudinal U-shaped block 8. The transverse foam strips 15 and the longitudinal foam strips 16, the buckle covers 17 and the thermal insulation decorative integrated panels 12 form a complete pattern, thereby improving the aesthetics of the wall panels.

[0072] After the thermal insulation and decoration integrated panel 12 is assembled, slurry is poured directly between the old building 1 and the thermal insulation and decoration integrated panel 12 to form a casting layer 2. The casting layer 2 is tightly attached to and fixed to the old building 1, thereby achieving an excellent thermal insulation and fixing effect in cooperation with the thermal insulation and decoration integrated panel 12.

[0073] When the thermal insulation decorative integrated panel 12 expands due to the principle of thermal expansion and contraction after long-term use, the thermal insulation decorative integrated panel 12 will squeeze the clamping groove 11 on one side, and the clamping groove 11 will further squeeze the corresponding transverse U-shaped block 7 and the longitudinal U-shaped block 8 with the help of the front baffle 10 and the rear baffle 9. Since the transverse U-shaped block 7 and the longitudinal U-shaped block 8 are made of elastic materials, they will resist and buffer the squeezing force, thereby avoiding squeezing damage to the thermal insulation decorative integrated panel 12. At the same time, when encountering a rainy environment, the design structure of the rear baffle 9 and the clamping groove 11 can be conducive to drainage, thereby further improving its durability.

[0074] The device can be used to decorate and renovate old buildings 1, thereby improving their aesthetics and durability. The components work together, are more compact, have a more reasonable structure, and have better linkage. At the same time, rainwater that occurs during actual use can be discharged more smoothly to avoid blockage and damage to the thermal insulation and decorative integrated panel 12 or the internal casting layer 2. At the same time, the thermal insulation and decorative integrated panel 12 can be shock-absorbing and buffered for thermal expansion and contraction or impact required during use, thereby improving its stability. Embodiment 3

[0075] like Figure 6-9 As shown, an external wall insulation structure for the renovation of old buildings is shown. In actual use, due to errors in the horizontal accuracy of the locking mechanism 18 or insufficient parallelism of adjacent locking mechanisms 18, the assembly accuracy and quality will be affected. At the same time, after the assembly is completed, it is still necessary to manually add adhesive to the inside of the first connecting groove and the second connecting groove to fix the internal transverse keel 3 and the longitudinal keel 4. In particular, the transverse keel 3 is located on the side of the longitudinal keel 4 close to the old building 1. Therefore, there is a misalignment between the transverse keel 3 and the longitudinal keel 4, which makes it difficult to fix and has poor fixing stability. In order to solve the above problems and improve the horizontal accuracy and assembly convenience of the device, the external wall insulation structure for the renovation of old buildings also includes: the transverse U-shaped block 7 is connected to the central position of the longitudinal U-shaped block 8 and a groove 21 is provided at one end close to the fixing rod 5, and the fixing rod 5 is provided with an assembly groove 19, and the assembly groove 19 is slidably connected to the inside of the assembly rod 20. The other end of the assembly rod 20 passes through the locking mechanism 18 and reaches the center position of the groove 21, so the assembly rod The mounting rod 20 can slide in the mounting groove 19. When the mounting rod 20 reaches the top of the mounting groove 19, the fixing rod 5 can be driven to move in the plug hole 13 to ensure that the fixing rod 5 is plugged into the bottom of the plug hole 13. A hanging rope 22 is provided at the inner top of the groove 21. A plumb bob 23 is provided at the bottom of the hanging rope 22. The plumb bob 23 can accurately measure the horizontality to ensure that it can accurately reach the appropriate position. A docking groove 24 is provided on one side of the plumb bob 23 close to the mounting rod 20. The docking groove 24 matches the mounting rod 20. And the height of the docking groove 24 is lower than the height of the assembly rod 20. Therefore, when the lead pendant 23 moves toward the end of the assembly rod 20, with the help of the limiting effect of the suspension rope 22, the lead pendant 23 will move obliquely upward, and the height of the docking groove 24 will rise accordingly. When the docking groove 24 rises to a suitable height, the docking groove 24 matches the assembly rod 20, and then the assembly rod 20 matches the docking groove 24. The lead pendant 23 can further move along the groove 21 toward the end of the fixed rod 5, thereby realizing the subsequent assembly buckle cover 17 and the release of the adhesive process.

[0076] A plurality of elastic airbags 25 are evenly arranged on the inner wall around the groove 21, and gas is arranged in the elastic airbags 25. The other end of the elastic airbags 25 is connected to the adhesive tube 26 through a one-way valve. Therefore, when the elastic airbags 25 are squeezed, the gas inside it will reach the adhesive tube 26 along the one-way valve. Foam glue is arranged in the adhesive tube 26. The adhesive tube 26 is evenly arranged with a plurality of discharge holes 27 in the direction away from the fixing rod 5. The other ends of the discharge holes 27 are connected to the first connecting groove and the second connecting groove through a one-way valve. When the adhesive tube 26 is squeezed, the foam glue inside will be discharged along the discharge holes 27, so as to reach the first connecting groove and the second connecting groove to adhere and fix the transverse keel 3 and the longitudinal keel 4, thereby improving the linkage and operability of the device.

[0077] The length of the lifting rope 22 is fixed and cannot be deformed. The length of the assembly rod 20 is greater than the length of the assembly groove 19. Therefore, when the lead sinker 23 is squeezed by the transverse keel 3 and moves toward the end of the fixed rod 5, the lead sinker 23 can match the assembly rod 20 after it is raised upward. The length of the lifting rope 22 mainly plays a role in limiting protection, and the assembly rod 20 extends into the groove 21 along the assembly groove 19, thereby ensuring that the assembly rod 20 can match the docking groove 24.

[0078] During use, as can be seen from the above, the fixing rod 5 is inserted into the plug hole 13, and the assembly rod 20 is inserted into the assembly groove 19, and then the assembly rod 20 passes through the locking mechanism 18 to reach the groove 21, and is located at the center position of the groove 21. The thermal insulation decorative integrated panel 12 is inserted and fixed between the locking mechanisms 18, and then the angle and position of the locking mechanism 18 are continuously adjusted. At the same time, the distance between the locking mechanism 18 and the old building 1 can be adjusted by means of the insertion depth of the fixing rod 5 in the plug hole 13, and the angle of the locking mechanism 18 can be adjusted by rotating the locking mechanism 18 along the assembly rod 20. After the adjustment is completed, it is ensured that the transverse keel 3 in the locking mechanism 18 is in a horizontal position, and the longitudinal keel 4 is in a vertical position, and adjacent locking mechanisms 18 are parallel to each other.

[0079] Then, the transverse keel 3 and the longitudinal keel 4 are placed in the first connecting groove and the second connecting groove in sequence, and the transverse keel 3 is located near one end of the fixing rod 5, and the transverse keel 3 and the longitudinal keel 4 are fixed by steel wires, etc., and the transverse keel 3 and the lead sinker 23 are in contact with each other. Then, the transverse foam strip 15 and the longitudinal foam strip 16 are assembled, and then the buckle cover 17 is engaged at the intersection of the transverse U-shaped block 7 and the longitudinal U-shaped block 8. At this time, the buckle cover 17 is squeezed and contacted with the longitudinal keel 4, and the longitudinal keel 4 squeezes the transverse keel 3, and the transverse keel 3 squeezes the lead sinker 23. The lead sinker 23 moves toward the end of the assembly rod 20. At the same time, due to the traction of the suspension rope 22 and its own weight, the lead sinker 23 is Due to the action of force, the plumb bob 23 is always in a vertical state, and when the plumb bob 23 tilts to one side, the plumb bob 23 is squeezed by the transverse keel 3 and moves toward the end of the assembly rod 20, the docking groove 24 in the plumb bob 23 cannot be adapted and plugged with the assembly rod 20, and after the outer surface of the plumb bob 23 is squeezed and contacted with the assembly rod 20, the position of the plumb bob 23 is limited, and the buckle cover 17 cannot be further plugged into the inside of the locking mechanism 18. Therefore, there is a step-like and uneven space between the buckle cover 17 and the transverse U-shaped block 7 and the longitudinal U-shaped block 8, which means that the locking mechanism 18 on this side has not reached the required horizontality and verticality, and its position angle needs to be further adjusted to achieve its installation accuracy.

[0080] When the plumb bob 23 moves upward obliquely with the movement of the transverse keel 3 and the traction of the suspension rope 22, and the docking groove 24 is plugged and fixed with the assembly rod 20, it means that the horizontal accuracy and vertical accuracy of the locking mechanism 18 meet the requirements. After that, the plumb bob 23 moves further toward the end of the fixing rod 5 with the help of the plug-in assembly of the docking groove 24 and the assembly rod 20. The plumb bob 23 will continuously squeeze the elastic air bag 25 located on the inner wall around the groove 21, and the air in the elastic air bag 25 will continuously move along the one-way valve to the adhesive tube 26. At the same time, the foam glue in the adhesive tube 26 is continuously discharged along the discharge hole 27 to the inside of the first connecting groove and the second connecting groove when being squeezed. With the help of the foam glue, the transverse keel 3 and the longitudinal keel 4 in the first connecting groove and the second connecting groove can be adhered and fixed, thereby effectively protecting them.

[0081] At the same time, when the docking groove 24 in the lead pendant 23 is assembled and fixed with the assembly rod 20, the lead pendant 23 will drive the assembly rod 20 to further move along the assembly groove 19, and the assembly rod 20 will drive the fixing rod 5 to move along the plug-in hole 13, thereby further correcting the parallelism between adjacent snap-fit ​​mechanisms 18 to ensure that after the buckle cover 17 is fixed, multiple snap-fit ​​mechanisms 18 are all on the same parallel plane, and the assembly rod 20 is at the optimal depth of the plug-in hole 13. After that, the thermal insulation decorative integrated panel 12 can be torn off and cleaned according to the above process to complete the assembly.

[0082] When the thermal insulation decorative integrated panel 12 is slowly deformed after long-term use, the structure of the transverse U-shaped block 7 and the longitudinal U-shaped block 8 can buffer and protect the extrusion force, thereby effectively preventing the thermal insulation decorative integrated panel 12 from being squeezed for a long time and then deformed and damaged. When the transverse U-shaped block 7 and the longitudinal U-shaped block 8 are squeezed, they will further squeeze the transverse keel 3 and the longitudinal keel 4, and the transverse keel 3 and the longitudinal keel 4 will further drive the lead pendant 23 to move toward the end of the fixed rod 5. At this time, the lead pendant 23 and the assembly rod 20 have been plugged in and fixed, so the assembly rod 20 will hinder the extrusion force, thereby preventing the lead pendant 23 from slowly moving toward the end of the fixed rod 5 and causing damage to the transverse U-shaped block 7 and the longitudinal U-shaped block 8.

[0083] When the thermal insulation decorative integrated panel 12 is subjected to a violent impact, it can be known from the above that the thermal insulation decorative integrated panel 12 will quickly squeeze the lead sinker 23 with the help of the transverse keel 3 and the longitudinal keel 4, and the lead sinker 23 will further squeeze the elastic airbag 25 when moving, so that the air inside it continues to reach the adhesive tube 26 along the one-way valve, and the foam glue in the adhesive tube 26 is quickly discharged along the discharge hole 27. The good elasticity of the foam glue can be used to decelerate and buffer the impact, thereby avoiding damage to the locking mechanism 18 caused by a large impact force, and further destroying the integrity and thermal insulation performance of the thermal insulation decorative integrated panel 12.

[0084] The device can effectively adjust and limit the horizontality and verticality of the thermal insulation decorative integrated panel 12 and the locking mechanism 18, so as to ensure that the actual assembly accuracy requirements are met. At the same time, when in use, the horizontal keel 3 and the longitudinal keel 4 can be bonded and fixed synchronously according to the actual installation requirements in combination with the adjustment of their horizontality, thereby further improving the stability and assembly efficiency of the device, saving energy and being environmentally friendly, having good thermal insulation effect and high assembly efficiency.

A straight connector 38 is provided on the other side of the upper horizontal plate 41, and a high-rise thermal insulation decorative plate is clamped inside the straight connector 38.

A T-shaped connecting piece 46 is provided on the other side of the lower horizontal plate 41, and a low-rise thermal insulation decorative outer panel 56 is clamped inside the T-shaped connecting piece 46. The T-shaped connecting piece 46 is mainly used to clamp and fix the lower-rise thermal insulation decorative outer panel 56, and the staggered arrangement of the low-rise thermal insulation decorative outer panel 56 under the clamping of the T-shaped connecting piece 46 can further improve the support stability and aesthetics of the bottom layer.

[0087] The I-shaped connector 38 includes a fixing plate 45, one side of which is fixedly connected to the cross plate 41, and the fixing plate 45 mainly plays a supporting and protective role. The upper half of the other side of the fixing plate 45 is provided with an upper U-shaped card plate 42, and the lower half of the other side of the fixing plate 45 is provided with a lower U-shaped card plate 44. The high-rise thermal insulation decorative outer panels 39 are all clamped to the upper U-shaped card plate 42 and the lower U-shaped card plate 44, and multiple groups of high-rise thermal insulation decorative outer panels 39 are placed parallel to each other. The high-rise thermal insulation decorative outer panels 39 are clamped and fixed by the upper U-shaped card plate 42 and the lower U-shaped card plate 44, so as to further improve the clamping effect and stability thereof. The gap between the upper U-shaped card plate 42 and the lower U-shaped card plate 44 can effectively perform shock absorption and buffering on the high-rise thermal insulation decorative outer panels 39, thereby effectively avoiding the high-rise thermal insulation decorative outer panels 39 from changing in volume or shape under the condition of thermal expansion and contraction, thereby causing damage to the T-shaped connector 46, effectively improving the assembly stability and adaptability, and meeting various working environments.

[0088] The T-shaped connecting piece 46 includes a horizontal U-shaped plate 47, and the other side of the horizontal U-shaped plate 47 is fixedly connected to the cross plate 41. The horizontal U-shaped plate 47 mainly serves to dampen the deformation of the low-layer thermal insulation decorative outer plate 56, effectively ensuring its adaptability. A first rear cross block 49 is provided at the top of the horizontal U-shaped plate 47 on the side away from the connecting plate 40, and a first front cross block 50 is provided on the other side of the first rear cross block 49.

The interiors of the two limiting grooves 54 are mutually clamped with the lower-layer thermal insulation decorative outer panel 56, and the clamping and fixing of the lower-layer thermal insulation decorative outer panel 56 by the first limiting groove 51 and the second limiting groove 54 further improves its clamping and fixing stability. At the same time, the first rear cross block 49 and the second rear cross block 52 can support and protect the lower-layer thermal insulation decorative outer panel 56, and the heights of the first rear cross block 49 and the second rear cross block 52 are greater than the first front cross block 50 and the second front cross block 53, and the first limiting groove 51 and the second limiting groove 54 are both inclined downward to both sides along the vertical U-shaped plate 48.
