[0002] With the transformation and upgrading of the construction industry, prefabricated buildings have been rapidly promoted, and various types of prefabricated components have emerged and been applied in engineering practice. Among them, the installation of prefabricated exterior walls is a key and difficult point in prefabricated technology, and its installation quality directly affects the quality, safety and durability of the building's exterior walls.

[0003] Traditional precast exterior wall installation typically relies on post-installed fasteners, which can lead to installation quality issues such as leakage due to non-standard installation and improper operation. Furthermore, the installation process is inconvenient and lacks safety and stability. Therefore, an ultra-thick precast insulated wall panel installation and fixing component was designed, enabling rapid and standardized installation of precast exterior walls, facilitating quality control of building exterior walls, and meeting green building requirements. Utility Model Content

The traditional prefabricated exterior wall installation on the market usually relies on post-installed fasteners, which are not standardized and are not operated in a standardized manner, which can easily cause installation quality problems such as leakage. In addition, the installation process is inconvenient and has poor safety and stability. Traditional installation methods also require drilling and adding additional fixation later, which not only increases material waste but may also damage the main structure and affect the overall stability of the structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-thick precast insulated wall panel installation and fixing assembly, comprising a precast GLC panel and a cast-in-place concrete beam. An embedded part is provided at the bottom of the cast-in-place concrete beam, and the upper part of the GLC panel is connected to the cast-in-place concrete beam via the embedded part at the bottom of the cast-in-place concrete beam. An insulation layer is provided in the middle of the precast GLC panel. A fixing screw penetrates the GLC panel from one side of the insulation layer. A connector, L-shaped, is provided inside the GLC panel, its top connected to the embedded part at the bottom of the cast-in-place concrete beam. The fixing screw passes through the GLC panel and through the connector, and is secured with a nut.

[0006] Preferably, the embedded part has a limit hole and an anchoring round steel bar.

[0007] Preferably, the anchoring round steel is located inside the cast-in-place concrete beam, and the anchoring round steel has a size of Φ10.

[0009] Preferably, a bolt is inserted through the oblong hole, and the diameter of the bolt is millimeters.

[0010] Preferably, a washer for preventing loosening is provided on the outside of the bolt.

[0011] Preferably, a preload rod for pre-tightening is installed on the side end of the bolt, and a shock-absorbing spring is provided on the outside of the preload rod.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This prefabricated structure ultra-thick wall panel green construction fixing device simplifies the construction process and reduces construction difficulty through the pre-embedded method of the main structure. Construction personnel can operate it without complicated training, significantly shortening the installation time of the ultra-thick insulation layer. Furthermore, the addition of pre-embedded parts reduces the need for subsequent drilling, avoids damage to the main structure by later fixing parts, reduces building material waste, avoids repair procedures due to structural damage, and saves resources. The specific details are as follows:

[0013] (1) The pre-embedded method of the main structure simplifies the construction process and reduces the construction difficulty. The addition of pre-embedded parts can reduce the drilling in the later stage, avoid damage to the main structure by the later fixing parts, and avoid the repair process caused by structural damage. The prefabricated GLC plate is connected by the fixing screw inside the side limit groove of the insulation layer, which improves the firmness and safety of the prefabricated insulation layer installation.

[0014] (2) The top fixing screw of the insulation layer is pre-positioned and embedded in the precast GLC plate. The subsequent operation is carried out according to the conventional process, which avoids the quality risk of damage to the main structure caused by the non-standard operation of the later fixing parts. The purpose of reducing quality risk is achieved. The anchoring round steel is stably connected through the limiting hole, which makes it convenient for the anchoring round steel to be clamped in the cast-in-place concrete beam, thus enhancing the integrity of the connection part.

[0015] (3) By pre-embedding the top embedded parts in advance, the quality risks to the building as a whole caused by non-standard operation during the installation of the top post-embedded parts and the insulation layer are reduced, the damage to the main structure is avoided, the delay and economic loss caused by accidents are reduced, and the construction quality risks are reduced.

[0016] (4) The elongated hole provides a certain adjustment space for bolt installation, which facilitates fine adjustment of the position of the connector during construction, improves installation efficiency, and the gasket on the outside of the bolt disperses the pressure generated when the bolt is tightened, enhances the friction of the connection part, and improves the overall installation stability.

[0017] (5) The pre-tightening rod on the bolt pre-tightens the connector of the insulation layer to ensure that the insulation layer will not loosen or shift after installation. The spring on the outside of the pre-tightening rod can buffer external vibration and impact through elasticity, absorb the small deformation caused by environmental changes or building stress, and extend the service life of the building.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: In this example, the embedded part 8 reduces the need for subsequent drilling, avoids damage to the main structure from subsequent fasteners, reduces building material waste, and avoids repair procedures due to structural damage. Figure 1 and Figure 2The technical solution shown includes a precast GLC slab 1, on which a cast-in-place concrete beam 2 is connected via embedded parts 8. An insulation layer 3 is provided on the side of the precast GLC slab 1, with a limiting groove 4 inside the insulation layer 3. A fixing screw 5 is installed inside the limiting groove 4, penetrating and connecting to the interior of the precast GLC slab 1. A connector 6 is provided on the outside of the fixing screw 5, and a nut 7 is threaded to the end of the fixing screw 5. Embedded parts 8 are provided on the precast GLC slab 1. This pre-embedded method simplifies the construction process, reduces construction difficulty, and allows construction personnel to operate without complex training. It significantly shortens the installation time of the ultra-thick insulation layer 3, accelerates project progress, saves labor costs, and reduces the need for later drilling by adding pre-embedded parts 8, achieving energy conservation and environmental protection. It avoids damage to the main structure caused by later fixing parts, reduces building material waste, avoids repair procedures due to structural damage, saves resources, and reduces construction waste. In line with green building principles, this design reduces maintenance costs, enhances the overall economic benefits of the project, and facilitates stable support for the upper cast-in-place concrete beam 2. This improves the building's ability to withstand external loads such as earthquakes and wind. The insulation layer 3 is connected to the precast GLC panel 1 via a fixing screw 5 inside the side-end limiting groove 4. The fixing screw 5 secures the connector 6 to the side of the precast GLC panel 1. The cooperation between the fixing screw 5 and the nut 7 ensures a stable connection between the precast GLC panel 1 and the connector 6, preventing loosening under stress during building use. This improves the robustness and safety of the prefabricated insulation layer 3 installation. By following the layout diagram of the insulation layer 3 during the main structure construction, only the top fixing screw 5 of the insulation layer 3 needs to be pre-positioned and embedded in the precast GLC panel 1. Subsequent operations follow standard procedures, avoiding quality risks and structural damage caused by improper post-installation of fixing components. This reduces quality risks and ensures the safety of the building structure.

[0028] Example 2: In this example, by pre-embedding the top embedded part 8, the quality risks to the overall building caused by improper operation during the installation of the top post-embedded part 8 and the insulation layer 3 are reduced, and damage to the main structure is avoided. Specifically, as follows... Figure 1 , Figure 3 and Figure 4As shown, the embedded part 8 has a limiting hole 9 and an anchoring round steel 10 is provided on the embedded part 8. The anchoring round steel 10 is located inside the cast-in-place concrete beam 2 and has a size of Φ10. The embedded part 8 is stably connected to the anchoring round steel 10 through the limiting hole 9, which facilitates the anchoring round steel 10 to be snapped into the cast-in-place concrete beam 2, enhances the integrity of the connection part, improves the structural force transmission efficiency, and effectively improves the load-bearing capacity and stability of the building structure. By pre-embedding the top embedded part 8, the quality risk caused to the overall building by non-standard operation during the installation of the top post-embedded part 8 and the insulation layer 3 is reduced, avoiding damage to the main structure, ensuring the connection and reliability between the main structure and the insulation layer 3, and timely and effectively reducing the accident of workers falling from heights near the edge of the post-fixed structure. At the same time, it reduces the construction period delay and economic loss caused by accidents and reduces the construction quality risk.

[0029] Example 3: In this example, the washer 13 on the outside of the bolt 12 disperses the pressure generated when the bolt 12 is tightened, preventing damage to the surface of the component due to excessive local pressure, and improving the overall stability of the installation. Specifically, as follows... Figure 1 and Figures 5-7 As shown, the connector 6 has an elongated hole 11 with dimensions of Φ13.5*40 mm. A bolt 12 with a diameter of 12 mm is inserted through the elongated hole 11. A washer 13 for preventing loosening is provided on the outside of the bolt 12. A pre-tightening rod 14 for pre-tightening is installed on the side of the bolt 12. A shock-absorbing spring 15 is provided on the outside of the pre-tightening rod 14. The elongated hole 11 on the connector 6 facilitates the installation of the bolt 12 and provides a certain adjustment space for the bolt 12 installation, which is convenient for fine-tuning the position of the connector 6 during construction, reducing the installation difficulty, improving the installation efficiency, and improving the stability of the connection. The washer 13 on the outside of the bolt 12 disperses the pressure generated when the bolt 12 is tightened. This prevents damage to the surface of components due to excessive local pressure, while also enhancing the friction of the connection points, effectively preventing bolt 12 from loosening and improving the overall installation stability. The pre-tightening rod 14 on bolt 12 pre-tightens the connector 6 of the insulation layer 3, ensuring that the insulation layer 3 will not loosen or shift after installation, thus ensuring the safety of the building. The spring 15 on the outside of the pre-tightening rod 14 can buffer external vibrations and impacts through elasticity, absorb minor deformations caused by environmental changes or building stress, and avoid loosening of the connection points due to vibration or deformation, further enhancing the stability and reliability of the device and extending the service life of the building.
