[0010] A construction method for a thermal insulation wall, characterized by comprising the following steps:

[0011] S1, insulation system preparation stage:

[0012] First, prepare and inspect the dimensions and quality of the internal and external load-bearing baseplates according to the design drawings to ensure they are free of damage and defects and meet the use standards. Surface treatment is then performed on the internal and external load-bearing baseplates to ensure they are clean, smooth, and free of oil and impurities to facilitate the subsequent installation of the insulation system. The internal and external load-bearing baseplates are then precisely positioned to ensure their horizontality and verticality meet the design requirements.

[0013] S2. Install the corrugated sealing layer:

[0014] Lay a corrugated sealing layer between the inner and outer load-bearing baseboards, check whether the corrugated sealing layer is laid evenly, and ensure that each seam of the corrugated sealing layer is intact; then fill the corrugated sealing layer with anti-pressure glue and let it stand for 12 hours to solidify. Avoid vibration or external extrusion during this period;

[0015] S3. Filling with insulation fluid:

[0016] Slowly inject the insulation fluid into the filling chamber to ensure that the fluid is evenly distributed and there is no leakage or gaps that are not filled in place. When injecting the insulation fluid, it is necessary to determine whether the insulation fluid has been completely filled and ensure that the fluid filling amount is not too much or too little to avoid poor sealing or insufficient space due to excessive filling;

[0017] S4. Check the tightness of the corrugated sealing layer:

[0018] Install a tightening ring in the middle of the corrugated sealing layer to fasten the insulation unit. At the same time, check whether the tightening ring is firm and whether its fixing effect on the corrugated sealing layer is stable.

[0019] S5. Manufacturing of buffer unit:

[0020] Fix the buffer layer between the two isolation layers using structural adhesive as required, ensuring the glue seam width is ≤ 2mm. After it is left to solidify, inspect it to form a buffer unit module with both buffering and support functions.

[0021] S6. Installation of buffer interlayer:

[0022] When installing the buffer interlayer, fix the buffer unit between the insulation units, check the flatness of each insulation unit to ensure that there is no folding or damage, and confirm that the outer sides of the two isolation layers in the buffer unit are in good contact with the corrugated sealing layer;

[0023] S7. Installation of insulation system:

[0024] Use lifting equipment to embed the insulation system into the building wall so that it is located in the middle of the building wall. After positioning, use cement to seal it. The sealing is divided into three pouring steps, and each time is vibrated and compacted for 2 hours. The final curing period is no less than 7 days.

[0025] The beneficial effects of the present invention are:

[0026] 1. Compared with the prior art, the thermal insulation wall of the present invention comprises a composite thermal insulation wall structure comprising an inner and outer load-bearing substrate, an insulation interlayer and a buffer interlayer. Its innovative design significantly improves the performance of the building wall in many aspects. First, the insulation interlayer adopts a combination of a corrugated sealing layer and an insulation fluid. The geometric characteristics of the corrugated structure expand the contact area between the fluid and the building structure, thereby enhancing the heat barrier capacity. The equidistant arrangement of the corrugated sealing layer makes the heat conduction path present a discontinuous distribution, effectively reducing the thermal bridge effect. Secondly, the insulation fluid in the filling chamber can absorb heat through phase change or molecular motion to inhibit heat transfer. Compared with traditional solid insulation materials, it has higher thermal capacity and dynamic adjustment ability. The setting of the buffer interlayer converts the dynamic load borne by the building structure into multi-directional stress components through the mechanical dispersion effect of the buffer unit, avoiding cracking of the insulation interlayer caused by stress concentration. In addition, the combination of the rigid support of the inner and outer load-bearing substrates and the flexible buffer interlayer not only ensures the overall stability of the wall structure, but also gives it adaptability to deformation. The modular design of the structure facilitates factory prefabrication and on-site assembly, shortening the construction period.

[0027] 2. The thermal insulation wall of the present invention fills the microscopic pores of the corrugated sealing layer through the potting process of the pressure-resistant adhesive, so that the density of the sealing layer reaches more than 98%, effectively blocking moisture penetration and air convection heat loss. At the same time, the use of the pressure-resistant adhesive can ensure that the corrugated sealing layer will not be deformed or damaged under long-term pressure, thereby improving the durability of the sealing layer; the circumferential prestressing of the tightening ring optimizes the stress form of the corrugated sealing layer; this combined technology improves the compressive strength of the insulation unit; in addition, the setting of the tightening ring ensures the stability of the corrugated sealing layer in the insulation unit, prevents the sealing layer from loosening or shifting due to external pressure or other factors, and ensures the durability and stability of the insulation effect; this design further enhances the thermal insulation performance of the wall, not only effectively isolates the transfer of heat, but also prevents the penetration of air and moisture, thereby improving the overall sealing and thermal insulation of the wall.

[0028] 3. In the present invention, one of the buffer units effectively improves the buffering and supporting capacity of the wall by adopting a unique design of a bow-shaped support seat and a pressure-bearing body; the cooperation between the concave curved support part and the convex curved contact part can provide more stable support, reduce the influence of external forces, and thus avoid deformation or damage of the insulation system due to temperature changes, earthquakes or other external vibrations; the setting of two isolation layers ensures good contact between the corrugated sealing layer and the buffer unit, effectively improves the buffering effect, and prevents displacement or damage due to pressure changes inside the wall; this buffer design not only increases the structural stability of the wall, but also improves its pressure resistance and seismic resistance in long-term use, making the insulation wall suitable for use in complex environments and can effectively extend the service life of the building.

[0029] 4. In the present invention, another buffer unit uses two layers of longitudinally symmetrically stacked corrugated sheets. This design provides a more uniform support force through the staggered crests and troughs, which can effectively disperse external impacts or pressure and avoid local deformation or damage. The design of the corrugated sheet enables each insulation unit to evenly distribute stress when under pressure, reducing the risk of single-point damage. In addition, the fixed connection between the crests of the corrugated sheet and the isolation layer ensures the stability of the structure, allowing the entire buffer unit to continuously provide stable support force. This structure is particularly suitable for buildings with high requirements for wall pressure, and has obvious advantages in earthquake resistance, pressure resistance, etc., which can effectively improve the safety and durability of the building. The excellent performance of the overall structure enables the buffer unit to maintain excellent performance under extreme conditions, thereby extending the service life of the wall and reducing maintenance costs.

DETAILED DESCRIPTION

[0033] Reference Figure 1-2 The thermal insulation wall and the construction method thereof according to the present invention are further described in detail.

[0034] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature.

[0036] Example 1

[0037] Figure 1 An insulating wall shown includes an insulation system disposed within a building wall 1, the insulation system comprising an inner load-bearing substrate 2, an outer load-bearing substrate 3, and an insulation interlayer disposed between the inner load-bearing substrate 2 and the outer load-bearing substrate 3. The insulation interlayer is composed of a plurality of equidistantly arranged insulation units 4, each insulation unit 4 including a corrugated sealing layer 5 sealed between the inner load-bearing substrate 2 and the outer load-bearing substrate 3. The space enclosed by the corrugated sealing layer 5 and the inner load-bearing substrate 2 and the outer load-bearing substrate 3 forms a filling chamber 6, which is filled with an insulation fluid.

[0038] The thermal insulation system further comprises a buffer interlayer provided between the inner load-bearing base plate 2 and the outer load-bearing base plate 3, wherein the buffer interlayer is composed of a plurality of buffer units 7 provided between the thermal insulation units 4;

[0039] Compared to existing technologies, the insulated wall of the present invention comprises a composite insulated wall structure comprising internal and external load-bearing substrates, an insulating interlayer, and a buffer interlayer. Its innovative design significantly improves the performance of the building wall 1 in multiple aspects. First, the insulating interlayer utilizes a corrugated sealing layer 5 combined with an insulating fluid. The geometric characteristics of the corrugated structure expand the contact area between the fluid and the building structure, thereby enhancing thermal insulation. The equidistant arrangement of the corrugated sealing layer 5 results in a discontinuous distribution of heat conduction paths, effectively reducing the thermal bridge effect. Second, the insulating fluid within the filling chamber 6 can absorb heat through phase change or molecular motion, inhibiting heat transfer, and possesses higher thermal capacity and dynamic adjustment capabilities compared to traditional solid-state insulation materials. The buffer interlayer, through the mechanical dispersion effect of the buffer units 7, converts the dynamic load borne by the building structure into multi-directional stress components, thus avoiding cracking of the insulating interlayer due to stress concentration. Furthermore, the combination of the rigid support of the internal and external load-bearing substrates and the flexible buffer interlayer ensures the overall stability of the wall structure while giving it adaptability to deformation. The modular design of the structure facilitates factory prefabrication and on-site assembly, shortening the construction period.

[0040] The corrugated sealing layer 5 is filled with a compression-resistant adhesive 8, and a tightening ring 9 for fastening the corrugated sealing layer 5 is provided in the middle of the corrugated sealing layer 5;

[0041] The thermal insulation wall of the present invention fills the microscopic pores of the corrugated sealing layer 5 through the potting process of the pressure-resistant adhesive 8, so that the density of the sealing layer reaches more than 98%, effectively blocking moisture penetration and air convection heat loss. At the same time, the use of the pressure-resistant adhesive 8 can ensure that the corrugated sealing layer 5 will not be deformed or damaged under long-term pressure, thereby improving the durability of the sealing layer; the circumferential prestressing of the tightening ring 9 optimizes the stress form of the corrugated sealing layer 5; this combination technology improves the compressive strength of the insulation unit 4; in addition, the setting of the tightening ring 9 ensures the stability of the corrugated sealing layer 5 in the insulation unit 4, prevents the sealing layer from loosening or shifting due to external pressure or other factors, and ensures the durability and stability of the insulation effect; this design further enhances the thermal insulation performance of the wall, not only effectively isolates the transfer of heat, but also prevents the penetration of air and moisture, thereby improving the overall sealing and thermal insulation of the wall.

[0042] Each of the buffer units 7 includes two isolation layers 10 and a buffer layer 11. The isolation layer 10 is vertically arranged between the inner load-bearing substrate 2 and the outer load-bearing substrate 3, and the outer side of the isolation layer 10 is in contact with the corrugated sealing layer 5. The buffer layer 11 is arranged between the two isolation layers 10, and the buffer layer 11 includes a bow-shaped support seat 12 fixed to the middle of the inner side of one of the isolation layers 10. A concave curved support portion 13 is provided on the top of the bow-shaped support seat 12. A pressure-bearing body 14 is fixed to the middle of the inner side of the other isolation layer 10, and a convex curved contact portion 15 is formed on the bottom surface of the pressure-bearing body 14. The radius of the convex curved contact portion 15 is less than 15% of the concave curved support portion 13, and the convex curved contact portion 15 is coaxially arranged with the concave curved support portion 13.

[0043] By adopting the unique design of the bow-shaped support seat 12 and the pressure-bearing body 14, the buffering and supporting capacity of the wall is effectively improved; the cooperation between the concave curved support part 13 and the convex curved contact part 15 can provide more stable support, reduce the influence of external forces, and thus avoid deformation or damage of the insulation system due to temperature changes, earthquakes or other external vibrations; the setting of the two-layer isolation layer 10 ensures good contact between the corrugated sealing layer 5 and the buffer unit 7, effectively improves the buffering effect, and prevents displacement or damage caused by pressure changes inside the wall; this buffering design not only increases the structural stability of the wall, but also improves its pressure resistance and seismic resistance in long-term use, making the insulation wall suitable for use in complex environments and can effectively extend the service life of the building.

[0044] A construction method for a thermal insulation wall, characterized by comprising the following steps:

[0045] S1, insulation system preparation stage:

[0046] First, prepare and check the size and quality of the inner and outer load-bearing base plates according to the design drawings to ensure that the base plates are free of damage and defects and meet the use standards. Perform surface treatment on the inner and outer load-bearing base plates 2 and 3 to ensure that their surfaces are clean, smooth, and free of oil and impurities to facilitate the subsequent installation of the insulation system. Then, accurately position the inner and outer load-bearing base plates 2 and 3 to ensure that their horizontality and verticality meet the design requirements.

[0047] S2. Install the corrugated sealing layer 5:

[0048] Lay the corrugated sealing layer 5 between the inner load-bearing base plate 2 and the outer load-bearing base plate 3, check whether the corrugated sealing layer 5 is laid evenly, and ensure that each seam of the corrugated sealing layer 5 is intact; then fill the corrugated sealing layer 5 with a pressure-resistant adhesive 8, and let it stand for 12 hours to solidify. During this period, avoid vibration or external extrusion.

[0049] S3. Filling with insulation fluid:

[0050] Slowly inject the insulation fluid into the filling chamber 6 to ensure that the fluid is evenly distributed and there is no leakage or gaps that are not filled in place. When injecting the insulation fluid, it is necessary to determine whether the insulation fluid is completely filled and ensure that the fluid filling amount is not too much or too little to avoid poor sealing or insufficient space due to excessive filling;

[0051] S4. Check the tightness of the corrugated sealing layer 5:

[0052] Install a tightening ring 9 in the middle of the corrugated sealing layer 5 to fasten the thermal insulation unit 4. At the same time, check whether the tightening ring 9 is firm and ensure that its fixing effect on the corrugated sealing layer 5 is stable.

[0053] S5. Manufacturing of buffer unit 7:

[0054] The buffer layer 11 is fixed between the two isolation layers 10 using structural adhesive as required, ensuring that the adhesive seam width is ≤ 2mm. After standing and curing, it is inspected to form a buffer unit 7 module with buffering and support functions;

[0055] S6. Installation of buffer interlayer:

[0056] When installing the buffer interlayer, fix the buffer unit 7 between the insulation units 4, check the flatness of each insulation unit 4 to ensure that there is no folding or damage, and confirm that the outer side surfaces of the two isolation layers 10 in the buffer unit 7 are in good contact with the corrugated sealing layer 5;

[0057] S7. Installation of insulation system:

[0058] Use hoisting equipment to embed the insulation system into the building wall 1 so that it is located in the middle of the building wall 1. After positioning, use cement to fill it. The filling is poured in three times, and vibrated and compacted every 2 hours. The final curing period is not less than 7 days.

[0059] The construction method of the present invention ensures the quality and performance of the insulation wall through a series of precise processes. First, through the surface treatment and precise positioning of the internal and external load-bearing substrates, the installation accuracy of the substrate is ensured, avoiding the unstable insulation performance caused by the unevenness or position deviation of the substrate; secondly, the potting pressure-resistant glue 8 of the corrugated sealing layer 5 can provide a better sealing effect during the curing process, reducing the penetration of heat and moisture, and improving the insulation effect; when filling the insulation fluid, it is required to ensure that the fluid is evenly distributed and avoid leakage, ensuring the optimal filling state of the insulation fluid, thereby further enhancing the insulation effect of the wall; in the subsequent manufacturing of the buffer unit 7 and the installation of the buffer interlayer, each step is strictly controlled to ensure the stability and durability of the entire insulation system; finally, potting and maintenance are carried out three times to ensure the firmness of the overall structure of the wall and the reliability of long-term use; the advantage of this construction method is that through precise technology and meticulous steps, the high quality and long-term stable performance of the insulation wall are guaranteed, which is particularly suitable for large-scale and high-demand construction projects.

[0060] Example 2

[0061] This embodiment is roughly the same as the embodiment 1, except that the buffer unit 7 in the heat preservation system is different. Figure 2 The insulating wall has a second type of buffer unit 7. Each of the buffer units 7 includes two insulating layers 10 and a buffer layer 11. The insulating layer 10 is vertically arranged between the inner load-bearing base plate 2 and the outer load-bearing base plate 3, and the outer side of the insulating layer 10 is in contact with the corrugated sealing layer 5. The buffer layer 11 is arranged between the two insulating layers 10, and the buffer layer 11 includes two layers of longitudinally symmetrically stacked corrugated sheets 16. The crests 17 and troughs 18 of adjacent sheets form a staggered support structure. The crests 17 of the two layers of corrugated sheets 16 are respectively fixedly connected to the insulating layer 10, and the troughs 18 are fixedly connected to each other.

[0062] Two layers of longitudinally symmetrically stacked corrugated sheets 16 are used. This design provides a more uniform support force through the staggered wave crests 17 and troughs 18 structure, which can effectively disperse external impact or pressure and avoid local deformation or damage. The design of the corrugated sheet 16 allows each insulation unit 4 to evenly distribute stress when under pressure, reducing the risk of single-point damage. In addition, the fixed connection between the wave crests 17 of the corrugated sheet 16 and the isolation layer 10 ensures the stability of the structure, allowing the entire buffer unit 7 to continuously provide stable support force. This structure is particularly suitable for buildings with high pressure-bearing requirements on the wall. It has obvious advantages in earthquake resistance and pressure resistance, and can effectively improve the safety and durability of the building. The excellent performance of the overall structure enables the buffer unit 7 to maintain excellent performance under extreme conditions, thereby extending the service life of the wall and reducing maintenance costs.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
