Description

Technical Field

[0001] This invention relates to the field of civil building wall technology, and in particular to a thermally insulated multi-story civil building wall structure. Background Technology

[0002] In the insulation walls of multi-story civil buildings, from the perspective of building materials, adding materials with thermal insulation functions to concrete can effectively block the transfer of heat and improve the thermal insulation performance of ordinary concrete. Alternatively, adding a thermal insulation interlayer of high-molecular organic and inorganic materials inside the wall can improve the wall's thermal insulation performance. Or, fixing a thermal insulation material with a low thermal conductivity and good thermal insulation effect to the building wall can increase the average thermal resistance of the wall, thereby achieving the effect of thermal insulation.

[0003] Chinese invention patent CN104131632B discloses a composite thermal insulation wall structure. The specific technical solution includes a wall constructed of insulated hollow blocks. Polystyrene foam boards are filled into the gaps between the hollow blocks. A clay-ceramic concrete layer is placed on the outer side of the inner surface of the hollow blocks. A polyurethane sound insulation board is placed between the inner surface of the hollow blocks and the clay-ceramic concrete layer. A sealing rubber strip is placed on the side of the polystyrene foam board. Ceramic blocks are built on the outer side of the sealing rubber strip. Mineral-coated cotton boards are adhered to the ends of the ceramic blocks and the inner surface of the hollow blocks. This simple structure effectively compensates for the heat loss caused by the gaps between the hollow blocks, increasing the overall thermal insulation performance of the building. Utilizing the properties of various materials, it possesses excellent fireproof, thermal insulation, and electrical insulation characteristics, making it highly practical.

[0004] Currently, in the use of existing insulated multi-story civil building wall structures, when the internal insulation layer is tightly filled, the wall temperature rises due to the influence of outdoor temperature. This causes the insulation material and insulation units to expand under heat, resulting in secondary stress deformation of the frame and wall. This expansion leads to cracking and damage, accelerating wall aging and shortening its service life. Conversely, when the internal insulation layer is loose, the wall temperature drops due to the influence of outdoor temperature, causing the insulation material and insulation units to shrink. This widens the gaps between insulation components, resulting in poor insulation performance. With long-term use, the insulation layer is prone to detachment, and its insulation effect declines year by year. When some insulation components need to be replaced, in prefabricated insulated walls with assembled components, the entire insulation layer must be replaced, resulting in high replacement costs. Furthermore, the use of multiple bolts for fixing makes the replacement process cumbersome.

[0005] Therefore, it is necessary to provide a thermally insulated multi-story civil building wall structure to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art where the insulation of building walls is affected by the outdoor environment, and the temperature rises and falls accordingly, causing the insulation material and heat insulation unit to expand and contract. When the insulation material and heat insulation unit expand, the frame and wall become cracked and damaged due to excessive deformation, and when they contract, gaps are formed in the wall, resulting in poor insulation performance. Furthermore, when some insulation components need to be replaced, in prefabricated insulation walls that are assembled and combined, the insulation layer must be replaced as a whole, which is costly and involves multiple bolts for connection and fixation, making the replacement process cumbersome.

[0017] Preferably, a connecting groove is provided on the outer wall of the concrete frame, and the interior of the connecting groove is filled with heat-insulating mortar. The interior of the heat-insulating mortar is provided with a mesh structure, and the interior of the concrete frame is provided with a steel mesh.

[0018] Compared with related technologies, the thermal insulation multi-story civil building wall structure provided by the present invention has the following beneficial effects:

[0019] 1. In this invention, four inner expansion shells and four gap sealing plates are set inside the concrete frame. The inner expansion shells and gap sealing plates are staggered. Insulation square columns are installed inside the inner expansion shells to form insulation module A. Gap filling insulation components and insulation cylinders are installed inside the gap sealing plates to form insulation module B. Insulation modules A and B together form a double-layer insulation layer inside the concrete frame. A locking structure is used to fix the positions of the inner expansion shells and gap sealing plates. An outer expansion drive structure and an inner expansion drive structure are used, utilizing the threaded drive between the positioning threaded column and the inner threaded cylinder. In spring and autumn, when outdoor temperature changes are small, the double-layer insulation layer inside the concrete frame is maintained by the action of the outer and inner expansion drive structures. The space is stable. When the outdoor temperature rises in summer, the four inner expansion shells contract towards the center under the action of the outward and inward expansion transmission structures, expanding the coverage space of the inner expansion shells within the concrete frame. The movable plate is lifted within the outer expansion shell, opening the chamber of the outer expansion shell and expanding the expansion space of the double insulation layer. This prevents excessive deformation of the concrete frame and wall, which could lead to bulging, cracking, and damage. When the outdoor temperature drops in winter, the inner expansion shells expand outward away from the center under the action of the outward and inward expansion transmission structures. The movable plate is pressed down within the outer expansion shell, compressing the double insulation layer and making the A and B insulation modules of the double insulation layer more compact. This prevents the joints between the insulation components from widening, which would reduce the insulation effect.

[0020] 2. In this invention, when replacing the insulation layer inside the concrete frame by setting an external expansion transmission structure, an internal expansion transmission structure, and a locking structure, the height of the conical plug and the pressing plate is raised by the rotation of the internal threaded cylinder. After the pressing plate is misaligned with the connecting plate, the gap sealing plate and the internal expansion cover can be removed from the concrete frame in sequence. The insulation square column and insulation round column, which serve as insulation units for insulation block A and insulation block B, can be flexibly disassembled, allowing for the replacement of damaged insulation units. The disassembly operation is simple, reducing replacement costs. The disassembly and installation steps are simple, and replacement is convenient.

[0021] 3. In this invention, by setting up a concrete frame and thermal insulation mortar, the concrete frame is reinforced with a foundation steel mesh on each surface layer of the positioning threaded column during the pouring process. When the surrounding walls are poured before construction, the concrete on both sides plays a protective role during the pouring process. When the surrounding walls are poured after construction, the concrete frame is positioned by setting up a first T-shaped embedded part and a second T-shaped embedded part. At the same time, the setting of thermal insulation mortar and connecting groove is conducive to leveling between the concrete frame and the surrounding walls, making the joint between the concrete frame and the surrounding walls tight and improving the thermal insulation performance.

[0022] 4. In this invention, the hollow support rods and threaded flexible rods in the insulated square columns and insulated cylindrical columns are respectively positioned for the outer layer insulation block, the inner layer insulation block, and the second columnar insulation block. They bend flexibly within the concrete frame, so that the outer layer insulation block, the first columnar insulation block, and the gap-filling insulation component are tightly arranged within the concrete frame to form the outer insulation layer, and the inner layer insulation block, the second columnar insulation block, and the gap-filling insulation component are tightly arranged within the concrete frame to form the inner insulation layer. During expansion and contraction, they are flexibly distributed to maintain density, so that the double insulation layer maintains excellent thermal insulation effect. Attached Figure Description

[0048] Example 1

[0049] like Figure 1 - Figure 7 As shown, where, Figure 1 This invention provides a three-dimensional schematic diagram of a thermally insulated multi-story civil building wall structure; Figure 2 This invention provides a schematic diagram of the structure of an outwardly expanding shell in a thermally insulated multi-story civil building wall structure; Figure 3This invention provides a schematic diagram of the internal structure of a concrete frame in a thermally insulated multi-story civil building wall structure.

Figure 6 This invention provides a schematic diagram of the outward expansion transmission structure in a thermally insulated multi-story civil building wall structure; Figure 7 This invention provides a schematic diagram of the internal expansion transmission structure in the wall structure of a thermally insulated multi-story civil building. This embodiment proposes a thermally insulated multi-story civil building wall structure, including a concrete frame 1. Four first T-shaped embedded parts 8 and four second T-shaped embedded parts 81 are fastened to the outer wall of the concrete frame 1. The four first T-shaped embedded parts 8 are respectively fastened to the side walls of the concrete frame 1. The second T-shaped embedded parts 81 are divided into two pairs and respectively fastened to the opposite side walls of the concrete frame 1. Four inner expansion shells 2 are slidably connected to the inner wall of the concrete frame 1. A gap sealing plate 3 is provided between each adjacent inner expansion shell 2. An outer expansion shell 31 is fixedly connected to the outer wall of each gap sealing plate 3. A movable plate 32 is slidably connected inside each outer expansion shell 31. A locking structure 7 is provided on the side walls of the concrete frame 1. The inner expansion shells 2 and the gap sealing plates 3 are both fastened to the inner wall of the concrete frame 1 through the locking structure 7. The interior of each shell 2 is filled with insulation module A, and insulation module B is filled between each two adjacent inner expansion shells 2. A positioning threaded post 5 is fixedly connected to the inner side wall of the concrete frame 1. An inner threaded cylinder 51 is threadedly sleeved on the outer side wall of the positioning threaded post 5. The inner threaded cylinder 51 is located between the four inner expansion shells 2. An inner expansion transmission structure 6 is fixedly connected to the outer side wall of the inner threaded cylinder 51. The sides of the inner expansion shells 2 that are close to each other are slidably connected to the inner expansion transmission structure 6. An outer expansion transmission structure 4 is provided between the movable plate 32 and the outer side wall of the inner threaded cylinder 51. A retaining ring 35 is sleeved on the outer side wall of the inner threaded cylinder 51. The side of the gap sealing plate 3 that is close to the inner threaded cylinder 51 abuts against the retaining ring 35. The outer expansion transmission structure 4 is fixedly connected to the retaining ring 35. The four gap sealing plates 3 abut against the outer side wall of the retaining ring 35 together. When the inner threaded cylinder 51 is threadedly sleeved on the positioning threaded post 5, the position of the gap sealing plate 3 remains stable.

[0050] The A insulation module includes an insulated square column 21, which is fixedly installed on the inner side wall of the inner expansion shell 2. The B insulation module includes a gap-filling insulation component 33 and an insulated cylinder 34, which is fixedly installed on the inner side wall of the concrete frame 1. The gap-filling insulation component 33 is fixedly installed on the side of the movable plate 32 near the insulated cylinder 34. The A insulation module and the B insulation module together cover the interior of the concrete frame 1, forming an insulation interlayer in the wall.

[0051] The bottom of the retaining ring 35 is provided with a slot 3501. The size of the slot 3501 is adapted to the end of the inner expansion shell 2 near the inner threaded cylinder 51. When the retaining ring 35 moves with the inner threaded cylinder 51 on the positioning threaded post 5, the retaining ring 35 intersects with the inner expansion shell 2 through the slot 3501, so that the retaining ring 35 can maintain the position of supporting the four gap sealing plates 3 when it moves with the inner threaded cylinder 51 into the concrete frame 1.

[0052] The external expansion transmission structure 4 includes a U-shaped connecting rod 41, a connecting plate 42, and a pressing plate 43. There are four U-shaped connecting rods 41, connecting plates 42, and pressing plates 43. The U-shaped connecting rods 41 are all fixedly connected to the side of the movable plate 32 away from the gap filling insulation component 33. The end of the U-shaped connecting rod away from the movable plate 32 passes through the side wall of the external expansion cover 31 and is fixedly connected to the connecting plate 42. One end of the four pressing plates 43 is rotated and sleeved on the outer side wall of the internal threaded cylinder 51. The connecting plates 42 are all snapped into the side of the pressing plate 43 near the positioning threaded post 5.

[0053] The side of the movable plate 32 away from the gap-filling insulation component 33 is threadedly connected to the outer expansion shell 31 with an auxiliary expansion structure 44. The auxiliary expansion structure 44 includes a threaded rod 4401 and a turntable 4402. The threaded rod 4401 is rotatably connected to the outer wall of the movable plate 32. The end of the threaded rod 4401 away from the movable plate 32 passes through the side wall of the outer expansion shell 31. The turntable 4402 is fixedly connected to the end of the threaded rod 4401 away from the movable plate 32. With the assistance of the auxiliary expansion structure 44, when it is necessary to expand or shrink the expansion space required for the B insulation module, rotating the turntable 4402 can drive the threaded rod 4401 to rotate on the outer expansion shell 31. The auxiliary expansion transmission structure 4 drives the movable plate 32 to move as a whole and change the position of the movable plate 32 inside the outer expansion shell 31.

[0054] The internal expansion transmission structure 6 includes a conical plug 61 and an arc-shaped expansion plate 62. The conical plug 61 is fixedly sleeved on the rod wall of the internal threaded cylinder 51 located inside the concrete frame 1. Four arc-shaped expansion plates 62 are provided, each located between the positioning threaded post 5 and the internal expansion cover 2. One end of each arc-shaped expansion plate 62 is movably hinged to the inner wall of the concrete frame 1. An arc-shaped surface 23 is provided on the side of the arc-shaped expansion plate 62 away from the positioning threaded post 5. The arc-shaped surface 23 is provided on the side of the internal expansion cover 2 near the positioning threaded post 5. The outer wall contacts the arc surface 23, and the inner wall of the arc expansion plate 62 abuts against the conical surface of the conical plug 61. The end of the inner threaded cylinder 51 away from the concrete frame 1 is fixedly connected to a rotating wheel 52. When the outer wall of the arc expansion plate 62 abuts against the arc surface 23, the inner threaded cylinder 51 is rotated to continue moving into the interior of the concrete frame 1. By changing the position of the conical surface of the conical plug 61 abutting against the arc expansion plate 62, the four arc expansion plates 62 are pushed to rotate simultaneously away from the inner threaded cylinder 51, thereby simultaneously pushing the four inner expansion shells 2 to move within the concrete frame 1.

[0055] A sealing plug 63 is fixedly connected to the circular surface of the conical plug 61 away from the concrete frame 1. A multi-layer heat-insulating hose 64 is fixedly sleeved on the outer wall of the sealing plug 63. The sealing plug 63 is fixedly sleeved on the outer wall of the inner threaded cylinder 51. The sealing plug 63 and the heat-insulating hose 64 fill the gap between the inner expansion shell 2 and the gap sealing plate 3 and the inner threaded cylinder 51, so that the interior of the concrete frame 1 is sealed and the heat insulation effect of the heat-insulating wall structure is improved.

[0056] In this embodiment, both the inner expansion shell 2 and the gap sealing plate 3 are secured by the locking structure 7. The inner wall of the inner expansion shell 2 is snapped onto the inner wall of the concrete frame 1, completely covering the interior of the concrete frame 1. At the same time, a gap is reserved between the inner expansion shell 2 and the inner threaded cylinder 51 for expanding the internal space of the concrete frame 1 and for use during installation. Multiple insulating square columns 21 filled in the inner expansion shell 2 form insulation module A. The insulating cylindrical column 34 and the gap filling insulation component 33 between two adjacent inner expansion shells 2 form insulation module B in the concrete frame 1. Insulation modules A and B together cover the interior of the concrete frame 1 to form an insulation interlayer. Two layers of insulating composite material are set in the inner and outer directions of the insulating cylindrical column 34 and the insulating square column 21, so that the insulation interlayer is a double insulation layer. The movable plate 32 moves flexibly in the outer expansion shell 31 through the outer expansion transmission structure 4 to provide outer expansion space for insulation module B. When the inner expansion shells 2 of the outer expansion transmission structure 4 contract and move in a circular shape with the positioning threaded column 5 through the inner expansion transmission structure 6, they provide inner expansion space for insulation module B.

[0057] When the outdoor air is stable in spring and autumn, the size of the insulation square column 21 is stable. In the inner expansion transmission structure 6, the conical plug 61 is fixedly connected to the inner threaded cylinder 51 and its position is stable. The position of the arc expansion plate 62 between the conical plug 61 and the arc surface 23 is stable, keeping the size of the space where the A insulation module is located stable. This ensures that the multiple insulation square columns 21 are in close contact and remain tight. The gap filling insulation component 33 on the movable plate 32 is inserted between the insulation cylinders 34. The position of the movable plate 32 on the outer expansion cover 31 is stable, keeping the size of the space where the B insulation module is located stable. The gap filling insulation component 33 is in close contact with the insulation cylinders 34 and remains tight. This ensures that the size of the insulation interlayer in the concrete frame 1 is stable, the structure is dense, the insulation wall maintains structural stability, and the insulation effect is stable.

[0058] When the outdoor high temperature in summer causes the wall temperature to rise, the insulation square column 21, the gap filling insulation component 33, and the insulation round column 34 accumulate a large amount of heat and expand within the concrete frame 1. Through the rotation of the internal threaded cylinder 51 on the positioning threaded column 5, the internal threaded cylinder 51 gradually moves towards the outside of the concrete frame 1. The base of the conical plug 61 moves towards the outside of the arc-shaped expansion plate 62. The A insulation module expands within the inner expansion shell 2. The inner expansion shell 2, under force, pushes the arc-shaped expansion plate 62 until it again contacts the conical curved surface of the conical plug 61. All four inner expansion shells 2 move closer to the center. The main card block 72 is at the main card interface 7. The internal movement of the inner expansion shell 2 expands the internal space of the inner expansion shell 2 to accommodate the volume change of the insulation square column 21. While the inner threaded cylinder 51 moves, it drives the pressing plate 43 and the retaining ring 35 to move to the outside of the concrete frame 1. With the assistance of the auxiliary expansion structure 44, the movable plate 32 moves to the inside of the outer expansion shell 31 through the U-shaped connecting rod 41. The internal space of the outer expansion shell 31 is used to fill the gap and fill the volume change of the insulation component 33 and the insulation column 34, expand the expansion space of the insulation interlayer, and avoid excessive deformation of the concrete frame 1 and the wall due to the force of the expansion of the insulation interlayer, which would cause cracks.

[0059] During winter, the low outdoor temperature causes the wall temperature to drop, resulting in a significant loss of heat accumulated in the insulated square column 21, gap-filling insulation component 33, and insulated cylindrical column 34 within the concrete frame 1. As the temperature decreases and the volume shrinks, the rotating positioning threaded column 5 moves inward into the concrete frame 1. The conical surface of the conical plug 61 pushes the arc-shaped expansion plate 62 away from the positioning threaded column 5. The arc-shaped expansion plate 62 pushes the arc-shaped surface 23, causing the main locking block 72 on the inner expansion cover 2 to penetrate deeper into the main locking interface 71, thus shrinking the internal space of the inner expansion cover 2. The pressing plate 43 pushes the connecting plate 42, which in turn drives the U-shaped connecting rod 41 and the auxiliary expansion structure 44 to push the movable plate 32 to move outward of the expansion shell 31, shrinking the space between two adjacent inner expansion shells 2. This makes the insulation square column 21 more compact after the volume shrinks inside the inner expansion shell 2, and the gap filling the space where the insulation component 33 and the insulation cylinder 34 are located becomes more compact after shrinkage. This prevents the insulation interlayer from becoming loose and producing large gaps in the concrete frame 1 when the volume shrinks due to cooling, thus improving the thermal insulation effect of the insulation wall at low outdoor temperatures.

[0060] Example 2

[0061] like Figure 2 and Figure 8 As shown, Figure 8This invention provides an exploded structural diagram of an insulated column in a multi-story civil building wall structure. Based on the same concept as Embodiment 1 above, this embodiment further proposes that the locking structure 7 includes a main locking interface 71, a main locking block 72, a secondary locking interface 73, and a secondary locking block 74. Four of each of the main locking interfaces 71, main locking blocks 72, secondary locking interfaces 73, and secondary locking blocks 74 are provided. The four main locking interfaces 71 are respectively opened on the side walls around the concrete frame 1, and each main locking interface 71 extends into the interior of the first T-shaped embedded part 8. The main locking blocks 72 are opened in pairs on the side walls around the concrete frame 1, and the secondary locking interfaces 73 extend into the interior of the first T-shaped embedded part 8. Extending into the interior of the second T-shaped embedded part 81, the main locking blocks 72 are all fixedly connected to the side of the inner expansion shell 2 away from the positioning threaded post 5, and the main locking blocks 72 are all locked inside the main locking interface 71. The secondary locking blocks 74 are all fixedly connected to the side of the gap sealing plate 3 away from the positioning threaded post 5, and the secondary locking blocks 74 are all locked inside the secondary locking interface 73. The main locking interface 71 and the main locking blocks 72 strengthen the locking relationship between the first T-shaped embedded part 8 and the concrete frame 1, and the main locking blocks 72 and the secondary locking interface 73 strengthen the locking relationship between the second T-shaped embedded part 81 and the concrete frame 1. The snap-fit ​​relationship of the concrete frame 1 allows the inner expansion shell 2 and the gap sealing plate 3 to be snapped onto the inner sidewall of the concrete frame 1 via the main snap-fit ​​block 72 and the secondary snap-fit ​​block 74, respectively. This allows the concrete frame 1 to be snapped onto the first T-shaped embedded part 8 and the second T-shaped embedded part 81 via the secondary snap-fit ​​interface 73 and the secondary snap-fit ​​block 74, thus enhancing the stability of the concrete frame 1. The inner expansion shell 2 has diffusion windows 22 on its sidewalls. The insulated square column 21 includes an outer insulation block 2101, an inner insulation block 2102, and a hollow support rod 2103. The outer insulation block 2101... Multiple inner insulation blocks 2102 and hollow support rods 2103 are provided. The hollow support rods 2103 are bolted to the side wall of the inner expansion shell 2. The outer insulation blocks 2101 and inner insulation blocks 2102 are fixedly sleeved on the outer side wall of the hollow support rods 2103. The outer insulation blocks 2101 abut against the inner side wall of the concrete frame 1. The inner insulation blocks 2102 abut against the side of the inner expansion shell 2 away from the concrete frame 1. Adjacent outer insulation blocks 2101 and inner insulation blocks 2102 are in contact with each other.The insulating cylinder 34 includes a first columnar insulating block 3401, a second columnar insulating block 3402, a threaded flexible rod 3403, and a limiting sealing plate 3404. Multiple first columnar insulating blocks 3401, second columnar insulating blocks 3402, threaded flexible rods 3403, and limiting sealing plates 3404 are provided. Each threaded flexible rod 3403 is threadedly connected to the inner wall of the concrete frame 1. Each first columnar insulating block 3401 and second columnar insulating block 3402 is sleeved on the outer wall of the threaded flexible rod 3403. Each limiting sealing plate 3404 is threadedly sleeved on the outer wall of the threaded flexible rod 3403 at the end away from the concrete frame 1. The first columnar insulating blocks 3401 and second columnar insulating blocks 3402 on the same threaded flexible rod 3403 are spaced apart. The adjacent columnar insulation blocks 3401 and 3402 are in contact with each other. The outer diameter of the first columnar insulation block 3401 is larger than that of the second columnar insulation block 3402. The outer wall of the gap-filling insulation component 33 has a recess that matches the size of the second columnar insulation block 3402. Both the first and second columnar insulation blocks 3401 are located in this recess. The first columnar insulation block 3401, the gap-filling insulation component 33, and the outer insulation block 2101 together form the outer insulation layer. The second columnar insulation block 3402, the gap-filling insulation component 33, and the inner insulation block 2102 together form the inner insulation layer. This creates a double-layer insulation structure inside the concrete frame 1, improving the thermal insulation and heat preservation performance of the building's exterior wall.

[0062] In this embodiment, during long-term use, some of the insulation square columns 21 and insulation round columns 34 age, and their insulation effect decreases, requiring replacement. Rotating the internal threaded cylinder 51 causes the pressing plate 43 to move, pushing the pressing plate 43 to rotate on the internal threaded cylinder 51 until it separates from the connecting plate 42. Continuing to rotate the internal threaded cylinder 51 until it separates from the positioning threaded column 5, the conical plug 61 is pulled out from between the arc-shaped expansion plates 62, and the retaining ring 35 is removed from between the gap sealing plates 3. Pulling the movable plate 32 causes the secondary locking block 74 on it to be pulled out from the secondary locking interface 73, allowing the movable plate 32 to be removed. The gap-filling insulation component 33 is installed on the movable plate 32 for easy replacement. The limiting sealing plate 3404 then... After unscrewing the threaded flexible rod 3403, the first columnar insulation block 3401 and the second columnar insulation block 3402 can be selectively replaced. The remaining intact insulation cylinders 34 can continue to be used without interference. Then, pull the inner expansion cover 2 to pull the main clamping block 72 out of the main clamping interface 71. The inner expansion cover 2 and the insulation square column 21 can then be removed from the concrete frame 1. The outer insulation block 2101 and the inner insulation block 2102 that need to be replaced can be removed from the hollow support rod 2103 for targeted replacement. The operation is simple. Unusable insulation components can be replaced in a targeted manner, while intact insulation components can be retained, reducing the replacement cost. Moreover, it can be disassembled by hand without the aid of external tools. The operation is simple and the replacement is convenient.

[0063] When installing the gap sealing plate 3, the threaded flexible rod 3403 can bend flexibly. After the gap filling insulation component 33 is inserted between multiple insulation cylinders 34, the gap sealing plate 3 is pushed to insert the sub-clamping block 74 into the sub-clamping interface 73. During this process, the gap filling insulation component 33 pushes the first columnar insulation block 3401 and the second columnar insulation block 3402 towards the sub-clamping interface 73. The threaded flexible rod 3403 bends adaptively through its own elasticity. After the insulation cylinder 34 matches the groove on the gap filling insulation component 33, it rebounds due to its own elasticity, causing the first columnar insulation block 3401 and the second columnar insulation block 3402 to return to their positions. This ensures that the insulation cylinder 34 fits the shape of the gap filling insulation component 33 and abuts against it, guaranteeing the tightness of the B insulation module.

[0064] Example 3

[0065] like Figure 5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that a connecting groove 91 is provided on the outer side wall of the concrete frame 1, and the interior of the connecting groove 91 is fitted with thermal insulation mortar 9. The interior of the thermal insulation mortar 9 is provided with a mesh structure, and the interior of the concrete frame 1 is provided with a steel mesh.

[0066] In this embodiment, when the thermal insulation building wall structure is constructed after the surrounding walls are poured, the first T-shaped embedded part 8 and the second T-shaped embedded part 81 are both embedded in the surrounding walls during the pouring of the concrete frame 1 to fix and position the concrete frame 1 to be constructed later. Before pouring the concrete frame 1, woven steel mesh is placed on all five sides of the concrete frame 1 for pouring to stabilize the shape of the concrete frame 1 and strengthen the strength of the concrete frame 1. At the same time, a connecting groove 91 is reserved between the concrete frame 1 and the surrounding walls and a fixed mesh is used to fill the gap between the concrete frame 1 and the surrounding walls, so that the connection between the concrete frame 1 and the surrounding walls is close.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
