Description

Technical Field

[0001] This utility model relates to a high-precision, non-removable, self-insulating mold frame device and a window opening structure containing the same. Background Technology

[0002] In the residential building sector, the construction precision of door and window openings directly impacts the overall building quality and energy efficiency. Traditional construction methods involve using wooden or steel formwork to erect the opening structure before pouring concrete. However, due to difficulties in controlling formwork deformation, differences in concrete shrinkage rates, and human error, the dimensional deviation of the openings typically exceeds ±10mm. This precision deficiency necessitates multiple re-measurements and dimensional corrections before door and window installation. Statistics show that a single project averages 3-5 repeated measurement steps, extending the installation cycle by over 40% and increasing construction costs by 25%-30%.

[0003] In the current technical system, construction companies generally adopt remedial measures after the fact: locally chiseling or filling excessive openings with mortar. This method not only damages the density of the concrete structure but also creates a discontinuous interface at the junction of the window frame and the opening. Engineering measurements have shown that this treatment method results in an extremely high rate of leakage around windows, and the shrinkage and cracking of the filling material further exacerbates the thermal bridging effect, causing energy loss in the building. Although some projects have attempted to use precast concrete lintels or standardized formwork systems to improve accuracy, problems such as low formwork reuse rates, inability to adapt to irregular openings, and separation of insulation structures still exist.

[0004] With the gradual improvement of building energy efficiency standards, more stringent indicators are being imposed on the thermal performance of building envelopes. The traditional construction method of separating the insulation layer and structural layer in window frame installation is no longer sufficient to meet airtightness requirements due to the presence of multiple construction joints. The market urgently needs a highly integrated door and window construction method that achieves high-precision control of opening formation and simultaneously solves the problems of structural self-insulation and formwork removal. By placing precision control upfront during the structural construction stage, the need for later dimensional correction is effectively eliminated, significantly reducing the increased material costs caused by discrepancies in installation time and dimensions resulting from re-measuring processes. This reduces the overall cost of the project and improves building energy efficiency and construction quality. Utility Model Content

[0076] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0077] Example 1

[0078] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment discloses a window opening structure, which includes a cast-in-place concrete wall 20, a main frame 10, and a high-precision, self-insulating, non-removable formwork device. The high-precision, self-insulating, non-removable formwork device includes multiple formwork profiles, which are assembled end-to-end into a frame structure for mounting the main frame 10. Each formwork profile includes an insulation layer 1, a sub-frame 2, and a profile plate 3. The main frame 10 is connected to the sub-frame 2, the insulation layer 1 is connected to one side of the sub-frame 2, and the profile plate 3 is connected to the end of the insulation layer 1 and sub-frame 2 facing away from the main frame 10 and is used to connect to the cast-in-place concrete wall 20.

[0079] In this embodiment, the insulation layer 1 is connected to the indoor side of the subframe 2, the profile plate 3 is connected to the insulation layer 1 and the subframe 2, the wall reinforcement is erected on the outer periphery of the high-precision self-insulating formwork device, and then concrete is poured, so that the profile plate 3 is connected to the cast-in-place concrete wall 20. The main frame 10 is set in the frame structure and connected to the subframe 2. The main frame 10 is installed on the sub-frame 2, effectively improving the control of window opening size accuracy, thereby effectively controlling the gap between the main frame 10 and the sub-frame 2, reducing the probability of water seepage at the window frame, improving the building's airtightness and thermal insulation effect. Furthermore, the insulation layer 1 provides thermal insulation, further enhancing the energy-saving effect of the high-precision, self-insulating formwork device, achieving high-precision control of opening formation, and simultaneously solving the problems of structural self-insulation and formwork removal. At the same time, it reduces the on-site workload for later window opening insulation termination, avoiding the impact of construction quality on the energy-saving effect at the window frame. On-site installation is convenient, eliminating the need for window opening edge formwork setting, making construction quality easier to control. It is highly industrialized and integrated, prefabricated in the factory, meeting the needs of building industrialization development. Simultaneously, the profile plate 3 connects the insulation layer 1 and the sub-frame 2, thereby improving the overall structural strength, effectively meeting the load-bearing and reliable connection requirements of the main frame 10, and further improving installation accuracy.

[0080] Subframe 2 is rectangular in shape, and adjacent subframe profiles can be connected by angle aluminum. Subframe 2 can be made of metal, which effectively enhances the connection strength between subframe 2 and the main frame 10, further improving the safety and stability of the window opening structure. Subframe 2 can also be made of polyurethane, further strengthening its thermal insulation effect. Alternatively, subframe 2 can be made of FRP (fiber reinforced polymer), further enhancing its thermal insulation effect.

[0081] The insulation layer 1 can be made of Class A fire-resistant insulation material. By using Class A fire-resistant insulation material to process and manufacture the insulation layer 1, the accuracy of window opening dimensions can be effectively improved in various scenarios, including cast-in-place concrete exterior walls, prefabricated component production, and exterior wall masonry. This effectively controls the gap between the main frame 10 and the sub-frame 2, reduces the probability of water seepage, improves the building's airtightness and insulation effect, and further enhances the energy-saving effect of the window opening structure.

[0082] The material of insulation layer 1 can also be an organic-inorganic composite insulation material. The insulation performance of the organic-inorganic composite Class A fireproof insulation material can ensure that, with the same thickness of insulation material, the strength meets the relevant product standard requirements, and the fire resistance reaches Class A2, without the need to further composite inorganic boards to enhance its strength and fire resistance.

[0083] The insulation layer 1 can also be made of graphene insulation material. This effectively ensures the insulation and fire resistance of the high-precision, self-insulating frame device, greatly improving its safety and stability.

[0084] The top surface of the insulation layer 1 is flush with the top surface of the subframe 2, which effectively avoids interference and ensures that the main frame 10 is set inside the frame structure and installed on the subframe 2. This effectively avoids gaps between the high-precision, non-removable self-insulating frame device and the main frame 10, further enhancing the thermal insulation effect and improving the waterproof effect.

[0085] In this embodiment, the insulation layer 1 is pressed onto the profile plate 3, making the connection between the insulation layer 1 and the profile plate 3 stable and reliable. Of course, the insulation layer 1 can also be bonded to the profile plate 3, that is, the insulation layer 1 and the profile plate 3 are connected by adhesive, which makes the installation connection convenient.

[0086] The formwork profile also includes reinforcing ribs 31, which are connected to the side of the profile plate 3 facing the cast-in-place concrete wall 20 and are connected to the cast-in-place concrete wall 20. The reinforcing ribs 31 have a strengthening function; by connecting the reinforcing ribs 31 to the profile plate 3, the structural strength of the profile plate 3 is effectively enhanced, thereby effectively strengthening the connection strength between the profile plate 3 and the insulation layer 1 and the cast-in-place concrete wall 20, further improving installation accuracy.

[0087] In this embodiment, the reinforcing rib 31 is integrally formed with the profile plate 3, so that the profile plate 3 protrudes outward along the side facing the cast-in-place concrete wall 20. This makes it easy to manufacture the reinforcing rib 31, which only needs to protrude outward, and also ensures high structural stability. The reinforcing rib 31 is located on the part of the profile plate 3 that connects to the insulation layer 1. The part of the profile plate 3 that connects to the subframe 2 is planar and abuts against the bottom surface of the subframe 2. The profile plate 3 can be attached to the subframe 2 by fasteners, adhesives, and / or welding. Of course, in other embodiments, the profile plate 3 may also protrude inward along the side facing the insulation layer 1.

[0088] In this embodiment, the width of the mold frame profile is the same as the thickness of the cast-in-place concrete wall 20, and the two sides of the mold frame profile are flush with the inner and outer sides of the cast-in-place concrete wall 20, respectively. Specifically, the inner side of the insulation layer 1 is flush with the inner side of the cast-in-place concrete wall 20, and the outer side of the subframe 2 is flush with the outer side of the cast-in-place concrete wall 20. The window opening structure also includes an external wall insulation layer 30, which is a non-removable insulation template erected on the outer side of the high-precision non-removable self-insulating mold frame device, so that the outer side of the subframe 2 abuts against the external wall insulation layer 30, and an inner template is erected on the inner side. By pouring concrete, the cast-in-place concrete wall 20 is connected to the high-precision non-removable self-insulating mold frame device, effectively improving the window opening size accuracy control effect.

[0089] The material of the external wall insulation layer 30 can be a Class A fireproof insulation material or an organic-inorganic composite insulation material. Preferably, the material of the external wall insulation layer 30 is a silicon graphene insulation material.

[0090] The formwork profile also includes a water-stop structure 32. One end of the water-stop structure 32 is connected to the side of the profile plate 3 facing the cast-in-place concrete wall 20, and the other end of the water-stop structure 32 extends downward and protrudes. The downward-protruding water-stop structure 32 on the bottom surface of the profile plate 3 further enhances the waterproofing effect of the window opening structure, preventing leakage problems that easily occur in the through-joint between traditional high-precision, non-removable self-insulating formwork devices and the cast-in-place concrete wall 20. Simultaneously, the water-stop structure 32 extends into and connects to the cast-in-place concrete wall 20, further enhancing the reliability of the connection.

[0091] In this embodiment, the water-stopping structure 32 is integrally formed with the profile plate 3, which facilitates processing and manufacturing and provides high structural strength. Specifically, the water-stopping structure 32 is located in the middle region of the profile plate 3.

[0092] The profile plate 3 can be made of metal, meaning that the profile plate 3, reinforcing ribs 31, and water-stop structure 32 are all made of metal. Using metal effectively enhances the structural strength of the profile plate 3, thereby strengthening the connection between the profile plate 3 and the insulation layer 1 and the cast-in-place concrete wall 20, further improving installation accuracy. Alternatively, the profile plate 3 can also be made of FRP, meaning that the profile plate 3, reinforcing ribs 31, and water-stop structure 32 are all made of FRP, further enhancing the thermal insulation effect.

[0093] The number of formwork frame components can be four or three, and the specific number is not limited. The formwork frame components can be processed and manufactured in the factory, and then assembled into a frame structure by mutual support at the construction site; alternatively, multiple formwork frame components can be assembled into a frame structure in the factory, and then the frame structure can be transported to the site for installation.

[0094] The high-precision, self-insulating formwork device also includes multiple corner connecting components 4. These components 4 are located outside the frame structure and are positioned at the corners of multiple formwork profiles, connecting adjacent profiles. The formwork profiles are prefabricated in the factory and then cut to the window opening size on-site. They are reliably connected using mechanical bolts via the corner connecting components 4 to form the high-precision, self-insulating formwork device. The corner connecting components 4 connect adjacent profiles. These components enhance the connection strength, ensuring high connection strength and stability, and facilitating easy installation.

[0095] The corner connecting component 4 includes two winglets at a certain angle, each winglet having a connecting hole for connecting to the subframe 2 of the mold frame profile, resulting in high connection stability.

[0096] Of course, multiple corner connecting components 4 can also be integrated and assembled on multiple mold frame profiles in the factory, so that there is no need to assemble on the construction site, making installation and use very convenient.

[0097] The high-precision, non-removable self-insulating formwork device also includes an inner formwork frame, which is set within the frame structure and detachably connected to multiple formwork profile components. The inner formwork frame strengthens the connection, allowing adjacent formwork profile components to be connected via it, resulting in high connection strength and greater stability; installation and connection are also convenient. Furthermore, after the cast-in-place concrete wall has been shaped to its final form, the inner formwork frame can be disassembled and recycled.

[0098] The high-precision, self-insulating formwork device also includes an embedded part 5. One end of the embedded part 5 is connected to the side of the profile plate 3 and the sub-frame 2 facing away from the main frame 10, and the other end of the embedded part 5 is located inside and connected to the cast-in-place concrete wall 20. The embedded part 5 is connected to the profile plate 3 and the sub-frame 2 by screws, which can penetrate into the hollow cavity of the sub-frame 2. The overall structure of the embedded part 5 is located inside the cast-in-place concrete wall 20, thereby effectively strengthening the connection between the high-precision, self-insulating formwork device and the cast-in-place concrete wall 20, and further improving the installation reliability.

[0099] The window opening structure also includes a finishing layer 40, which is connected to the outer side of the external wall insulation layer 30 facing away from the cast-in-place concrete wall 20 and / or the inner side of the cast-in-place concrete wall 20 facing away from the external wall insulation layer 30. The finishing layer 40 provides enhanced protection, ensuring the proper functioning of the window opening structure. The finishing layer 40 comprises mortar and a mesh fabric. The mortar is connected to the outer side of the external wall insulation layer 30 facing away from the cast-in-place concrete wall 20, and the mesh fabric is embedded within the mortar. The mesh arrangement within the mortar enhances the overall structural strength of the finishing layer 40, while the mortar provides leveling and protection. Preferably, the mortar is a polymer-modified crack-resistant mortar.

[0100] The window opening structure also includes a finishing layer, which can be attached to the outer side of the external wall insulation layer 30 facing away from the cast-in-place concrete wall 20, or directly attached to the outer side of the plaster layer 40. The finishing layer protects the wall, beautifies the building, and meets functional requirements. The material for the finishing layer can be paint, ceramic tile, stone, metal sheet, or UHPC. When the finishing layer is made of UHPC, a reinforcing mesh structure is added within the finishing layer. This reinforcing mesh structure effectively strengthens the structural strength of the finishing layer, greatly improving the stability of the window opening structure.

[0101] Example 2

[0102] like Figure 5 As shown, the parts of the high-precision, self-insulating mold frame device that are the same as those in Embodiment 1 in this Example 2 will not be repeated; only the differences will be described. In this Example 2, the bottom surface of the insulation layer 1 is flush with the side of the subframe 2 facing away from the main frame 10. The profile plate 3 is horizontal and connected to the bottom surface of the subframe 2 and the insulation layer 1. The profile plate 3 is horizontal and does not have uneven reinforcing ribs 31, making the overall structure of the profile plate 3 simple, easy to process and manufacture, and low in cost. At the same time, the bottom surface of the insulation layer 1 is flush with the bottom surface of the subframe 2 and connected to the profile plate 3, which facilitates the processing and manufacturing of the mold frame profile.

[0103] In this embodiment 2, the subframe 2 and the profile plate 3 are separate structures, with the profile plate 3 connected to the bottom surface of the subframe 2 and the insulation layer 1. Of course, in other embodiments, the subframe 2 and the profile plate 3 can also be integrally formed, which facilitates processing and manufacturing and provides high structural connection strength.

[0104] Example 3

[0105] like Figure 6 As shown, the parts of the high-precision, self-insulating formwork device that are the same as those in Example 1 in this embodiment 3 will not be repeated; only the differences will be described. In this embodiment 3, the reinforcing rib 31 and the profile plate 3 are separate structures. The profile plate 3 is horizontal, with its top surface connected to the bottom surface of the subframe 2 and the insulation layer 1. The reinforcing rib 31 is connected to the bottom surface of the profile plate 3 and to the cast-in-place concrete wall 20, effectively strengthening the structural strength of the profile plate 3. At the same time, it effectively strengthens the connection strength between the formwork profile and the cast-in-place concrete wall 20, further improving the installation accuracy.

[0106] In this embodiment 3, there are multiple reinforcing ribs 31, which are spaced apart on the part of the profile plate 3 corresponding to the insulation layer 1.

[0107] In this embodiment 3, the reinforcing rib 31 is a winged angled section, with both ends of the winged angled section connected to the profile plate 3 by screws. The reinforcing rib 31 is detachably connected to the profile plate 3 by screws, making installation convenient and ensuring high connection stability. The two ends of the winged angled section are connected to the profile plate 3 by screws, and the middle area of ​​the winged angled section protrudes downwards along the direction close to the cast-in-place concrete wall 20. The overall structure is simple and easy to process and manufacture.

[0108] Example 4

[0109] like Figure 7As shown, the parts of the high-precision, non-removable self-insulating formwork device in Embodiment 4 that are the same as those in Embodiment 3 will not be repeated; only the differences will be described. In Embodiment 4, the reinforcing rib 31 is a square steel tube, which is welded to the profile plate 3. This ensures high stability in the connection between the reinforcing rib 31 and the profile plate 3, further strengthening the overall structural strength of the formwork profile; at the same time, it effectively strengthens the connection strength between the formwork profile and the cast-in-place concrete wall 20, further improving installation accuracy. Of course, in other embodiments, the square steel tube can also be riveted to the profile plate 3.

[0110] Example 5

[0111] like Figure 8 and Figure 9 As shown, the parts of the high-precision, self-insulating frame device without disassembly in this embodiment 5 that are the same as those in embodiment 1 will not be repeated; only the differences will be described. In this embodiment 5, the high-precision, self-insulating frame device without disassembly also includes a blocking structure 33. The blocking structure 33 is located on the side of the sub-frame 2 facing away from the interior, and one end of the blocking structure 33 is connected to the profile plate 3. The other end of the blocking structure 33 extends upward and protrudes, protruding from the top surface of the sub-frame 2. The sub-frame 2 has an upwardly protruding blocking structure 33 at the end facing the exterior, which makes the height of the frame structure facing the interior lower than the height facing the exterior. That is, in the high-precision, self-insulating frame device without disassembly, the height of the frame structure inside the interior is relatively low, and the height of the frame structure outside the interior is relatively high, so that the main frame 10 can be installed from the interior into the frame structure, thus making the installation connection very convenient. At the same time, the main frame 10 is installed from the interior into the frame structure and abuts against the blocking structure 33, thereby achieving precise positioning and installation of the main frame 10.

[0112] In this embodiment 5, the profile plate 3 and the blocking structure 33 are integrally formed. The blocking structure 33 is located at the outdoor-facing end of the profile plate 3 and can be manufactured by bending it upwards, which facilitates manufacturing and ensures high structural stability. The profile plate 3 and the blocking structure 33 are attached to the outer surface of the subframe 2.

[0113] In this embodiment 5, the window opening structure also includes a heat insulation pad, which is connected between the main frame 10 and the sub-frame 2, thereby effectively avoiding gaps between the high-precision self-insulating frame device and the main frame 10, enhancing the heat insulation effect, and also improving the waterproof effect.

[0114] Example 6

[0115] like Figure 10 and Figure 11As shown, the parts of the window opening structure in this embodiment 6 that are the same as those in embodiment 5 will not be repeated; only the differences will be described. In this embodiment 5, there is one insulation layer 1 connected to the inner side of the subframe 2. In this embodiment 6, there are two insulation layers 1, which are respectively connected to both sides of the subframe 2. The subframe 2 is located between the two insulation layers 1, so that the subframe 2 is located in the middle area of ​​the frame profile and is used to install the main frame 10. The insulation layers 1 on both sides further enhance the building's airtightness and thermal insulation effect.

[0116] In this embodiment 6, the profile plate 3 is connected to the subframe 2 and to the two insulation layers 1 on both sides of the subframe 2. This connection between the profile plate 3, the subframe 2, and the two insulation layers 1 improves the overall structural strength of the mold frame profile, effectively meets the load-bearing and reliable connection requirements of the main frame 10, and further improves the installation accuracy.

[0117] In this embodiment 6, the external wall insulation layer 30 is connected to the outer surface of the cast-in-place concrete wall 20. The width of the formwork profile is the same as the thickness of the cast-in-place concrete wall 20 and the external wall insulation layer 30, and the two sides of the formwork profile are flush with the inner surface of the cast-in-place concrete wall 20 and the outer surface of the external wall insulation layer 30, respectively. This eliminates the need to install pads on the outside of the formwork profile, making construction convenient and effectively enhancing the insulation effect of the window opening structure.

[0118] Example 7

[0119] like Figure 12 As shown, the parts of the high-precision, self-insulating frame device that is the same as that in Embodiment 6 in this Example 7 will not be repeated; only the differences will be described. In this Example 7, the profile plate 3 has a reinforcing part 34 on the side facing the insulation layer 1. The reinforcing part 34 extends into the insulation layer 1 and is connected to it. The reinforcing part 34 has a reinforcing function and is connected to the insulation layer 1, thereby effectively strengthening the connection strength between the profile plate 3 and the insulation layer 1.

[0120] In this embodiment 7, there are two reinforcing parts 34, located at both ends of the profile plate 3 and bent upwards. The structure is simple and easy to manufacture. Of course, in other embodiments, the reinforcing parts 34 can also be other structures that extend into the insulation layer 1 and connect with it, as long as they can enhance the structural connection strength. The number of reinforcing parts 34 is also not limited.

[0121] Example 8

[0122] like Figure 13 and Figure 14As shown, the parts of the window opening structure in this embodiment 8 that are the same as those in embodiment 6 will not be repeated; only the differences will be described. In this embodiment 8, the width of the formwork profile is the same as the thickness of the cast-in-place concrete wall 20, and both sides of the formwork profile are flush with the inner and outer sides of the cast-in-place concrete wall 20, respectively. Specifically, the inner and outer sides of the two insulation layers 1 are flush with the inner and outer sides of the cast-in-place concrete wall 20. During construction, inner and outer formwork are erected on the inner and outer sides of the high-precision, self-insulating formwork device, respectively. Concrete is poured to connect the cast-in-place concrete wall 20 with the high-precision, self-insulating formwork device. Then, the outer wall insulation layer 30 is installed on the outer side of the cast-in-place concrete wall 20 and the high-precision, self-insulating formwork device.

[0123] In this embodiment 8, the external wall insulation layer 30 is not a non-removable insulation template but is installed using a post-attachment method. The window opening structure also includes an adhesive layer, which is connected to the outer surface of the cast-in-place concrete wall 20 and the high-precision non-removable self-insulating template device, and is also connected to the external wall insulation layer 30. The adhesive layer further strengthens the connection strength of the external wall insulation layer 30, effectively preventing it from falling and greatly improving the safety and stability of the window opening structure.

[0124] Example 9

[0125] like Figure 15 and Figure 16 As shown, the parts of the high-precision, self-insulating frame device without disassembly in this embodiment 9 that are the same as those in embodiment 8 will not be repeated; only the differences will be described. In this embodiment 9, the high-precision, self-insulating frame device without disassembly also includes a blocking structure 33. The blocking structure 33 is located on the side of the sub-frame 2 facing away from the interior, with one end connected to the profile plate 3 and the other end extending upwards and protruding from the top surface of the sub-frame 2. The blocking structure 33 is located between the sub-frame 2 and the insulation layer 1 and protrudes from the top surface of the sub-frame 2, allowing the main frame 10 to be installed from the interior into the frame structure, thus making installation and connection very convenient. Simultaneously, the main frame 10 is installed from the interior into the frame structure and abuts against the blocking structure 33, thereby achieving precise positioning and installation of the main frame 10. The profile plate 3 and the blocking structure 33 are integrally formed.

[0126] Example 10

[0127] like Figure 17 and Figure 18As shown, the parts of the high-precision, self-insulating formwork device that are the same as those in Embodiment 1 in this Example 10 will not be repeated; only the differences will be described. In this Example 10, the thickness of the insulation layer 1 is less than the thickness of the sub-frame 2, and the end of the sub-frame 2 facing away from the main frame 10 extends downward and protrudes from the bottom surface of the insulation layer 1. The greater thickness of the sub-frame 2 and its protrusion from the bottom surface of the insulation layer 1 create a stepped waterproof structure between the insulation layer 1 and the sub-frame 2. This allows the sub-frame 2 to further enhance the waterproof effect of the window opening structure, eliminating the leakage problem that easily occurs in the through-joint between the traditional high-precision, self-insulating formwork device and the cast-in-place concrete wall 20. At the same time, the sub-frame 2 extends into the cast-in-place concrete wall 20 and connects with it, further enhancing the reliability of the connection.

[0128] In this embodiment 10, the profile plate 3 is connected to the bottom surface of the insulation layer 1 and the side surface of the subframe 2 and is used to connect with the cast-in-place concrete wall 20. The profile plate 3 is connected to the side surface of the subframe 2 by fasteners, resulting in high connection strength.

[0129] In this embodiment 10, the profile plate 3 is bent, so that the profile plate 3 is connected to the bottom surface of the insulation layer 1 and the inner side surface of the subframe 2. The embedded part 5 is directly connected to the bottom of the subframe 2.

[0130] Example 11

[0131] like Figure 19 As shown, the parts of the high-precision, self-insulating frame device that is the same as that in Embodiment 10 will not be repeated; only the differences will be described. In Embodiment 11, the high-precision, self-insulating frame device also includes a blocking structure 33. The blocking structure 33 is located on the side of the sub-frame 2 facing away from the interior, and one end of the blocking structure 33 is connected to the profile plate 3. The other end of the blocking structure 33 extends upward and protrudes, protruding from the top surface of the sub-frame 2. The blocking structure 33 is located between the sub-frame 2 and the insulation layer 1 and protrudes from the top surface of the sub-frame 2, allowing the main frame 10 to be installed from the interior into the frame structure, thus making the installation connection very convenient. At the same time, the main frame 10 is installed from the interior into the frame structure and abuts against the blocking structure 33, thereby achieving precise positioning and installation of the main frame 10. The profile plate 3 and the blocking structure 33 are integrally formed, and the profile plate 3 and the blocking structure 33 are attached and connected to the sub-frame 2.

[0132] Example 12

[0133] like Figure 20As shown, the high-precision, self-insulating frame device without disassembly in this embodiment 12 will not be repeated for the parts that are the same as in embodiment 11; only the different parts will be described. In this embodiment 12, the profile plate 3 is a split structure, not a one-piece molded structure, and the inner side of the subframe 2 has an insulation layer 1. The profile plate 3 includes a split first profile component 35 and a second profile component 36, which are respectively connected to the two sides of the subframe 2. Specifically, the profile plate 3 is connected to the inner side of the subframe 2 and the bottom surface of the insulation layer 1 through the first profile component 35, and the profile plate 3 is connected to the outer side of the subframe 2 through the second profile component 36 by screws, with the top of the second profile component 36 protruding from the top surface of the subframe 2 to form a blocking structure 33. The profile plate 3 is connected to the two sides of the subframe 2 through the first profile component 35 and the second profile component 36, which reduces the bending structure of the profile plate 3, making it easier to process and manufacture; at the same time, it saves materials, has low cost, and has a simple structure.

[0134] Example 13

[0135] like Figure 21 and Figure 22 As shown, the parts of the high-precision, non-removable self-insulating frame device in this embodiment 13 that are the same as those in embodiment 12 will not be repeated; only the differences will be described. In this embodiment 13, the inner and outer sides of the subframe 2 have insulation layers 1. The split first profile 35 and the second profile 36 are respectively connected to the two sides of the subframe 2 and connected to the two insulation layers 1 on both sides.

[0136] In this embodiment 13, the profile plate 3 has grout penetration holes 37, which connect the cast-in-place concrete wall 20 and the insulation layer 1. During concrete pouring, the concrete flows into the grout penetration holes 37 and connects with the insulation layer 1, thereby effectively increasing the contact area between the cast-in-place concrete wall 20 and the insulation layer 1. This ensures that the high-precision, non-removable self-insulating formwork device does not affect the bonding force between the cast-in-place concrete wall 20 and the insulation layer 1 after installation, achieving a more stable connection.

[0137] In this embodiment 13, the external wall insulation layer 30 is connected to the outer surface of the cast-in-place concrete wall 20. The width of the formwork profile is the same as the thickness of the cast-in-place concrete wall 20 and the external wall insulation layer 30, and the two sides of the formwork profile are flush with the inner surface of the cast-in-place concrete wall 20 and the outer surface of the external wall insulation layer 30, respectively. This eliminates the need to install pads on the outside of the formwork profile, making construction convenient and effectively enhancing the insulation effect of the window opening structure.
