[0044] The production and installation method of the present invention is as follows:

[0045] Factory production steps:

[0046] S1. Profile cutting and pretreatment: Use a CNC cutting machine to cut the aluminum alloy profile according to standard length (such as the reference length of the window frame substrate 202 and the outer frame substrate 102 is 1.2m / 1.5m), and the extension part is produced in sections according to the 50mm module. The surface is anodized or powder sprayed (film thickness ≥ 60μm);

[0047] S2. Modular component processing: pre-install the splicing plate on the window frame substrate 202 and the outer frame substrate 102, slot and embed the PA66 insulation strip, the broken bridge aluminum profile cavity is designed as a multi-cavity structure, and the plug-in guide groove of the telescopic plug 301 is reserved;

[0048] S3. Extension assembly: The extension is pre-set with a gas-tight rubber strip 204 slot, and the end is processed with a dovetail structure to match the telescopic plug 301 to ensure continuous sealing after insertion;

[0049] S4. Pre-installation of hardware and security system: Install hinge 400, limit rod 500 and push-pull handle 700 on the side of window frame substrate 202, integrate electromagnetic lock 602 circuit board simultaneously, weld wires and encapsulate with waterproof glue;

[0050] S5. The spring buckle 601 and the spring buckle 601 are fixed to the edge of the window sash after passing the pressure test (≥5000 times of opening and closing) to ensure the reliability of mechanical locking;

[0051] S6. Glass unit packaging: embed the double-layer thickened glass 205 into the window frame 200, seal it with EPDM strips, fix it with glue (silicone structural glue) around the glass, and perform air tightness test (no leakage at a pressure difference of 500Pa). The thickened glass 205 and the window frame 200 are vertically pressed and fixed. The size of the thickened glass 205 is consistent with the size of the window frame substrate 202 and the window frame extension 203 when the telescopic plug 301 is fully extended; when the window frame extension 203 retracts, the edge of part of the thickened glass 205 is hidden in the window frame 200.

[0052] S7. Pre-assembly and quality inspection of the entire window: temporarily connect the window frame 200 and the outer frame 100 through the splicing plug-in 302, test the telescopic adjustment function (50mm stroke), verify the electromagnetic lock 602 linkage alarm and Internet of Things signal transmission (such as ZigBee connection), and finally disassemble it into modular component packaging.

[0053] On-site installation steps:

[0054] T1. Hole measurement and substrate positioning: Use a laser rangefinder to check the wall hole size and mark the installation reference line of the outer frame substrate 102. When the error exceeds 5mm, the extension adjustment is triggered;

[0055] T2. Telescopic adjustment of the extension part: Slide the outer frame extension part 103 and the window frame extension part 203, adjust the telescopic plug-in 301, the base plate and the extension plate made of broken bridge aluminum to the target length (such as compensating for a 15 mm gap), and lock the insertion joint with self-tapping screws (M5×25 mm) to ensure that the dovetail tenon is fully engaged with the guide groove.

[0056] T3. Check the penetrability of the drainage channel and adjust the coaxiality of the water guide groove and the drainage hole of the base plate (deviation ≤ 0.5 mm);

[0057] T4. Fixing the outer frame 100 and the window frame 200: Embed the entire outer frame 100 into the opening, anchor the four corners with expansion bolts (M8×80 mm), inject foam glue to fill the gap, and apply weather-resistant sealant at the joint between the outer frame splicing plate 101 and the wall;

[0058] T5. Hang the window frame 200 to the outer frame 100 through the hinge 400, adjust the opening angle with the limit rod 500 (usually limited within 45°), and check the uniformity of the gaps around the window sash after closing (≤ 2 mm);

[0059] T6. Activate the security system: Connect the power cord through the through holes on the outer frame 100 and the window frame 200 to connect the electromagnetic lock 602, configure the Internet of Things module (such as an NB-IoT chip), and bind the alarm permissions of the user's mobile phone or computer terminal;

[0060] T7. Test the locking force of the spring buckle 601: Apply a 50 N thrust to verify whether the spring buckle 601 triggers the alarm of the electromagnetic lock 602, and simultaneously check the cloud alarm response delay.

[0061] T8. Inject glue (polyurethane sealant) through the injection hole at the joint of the splicing plug-in 302 and the telescopic plug-in 301, install the windproof cover plate to cover the drainage hole, and complete the delivery.

[0062] The working principle of the present invention:

[0063] Through the modular structure design and the integration of an intelligent security system, the present invention realizes the efficient coordinated operation of the standardized mass production of aluminum alloy doors and windows in the factory and the rapid adaptation and installation on site. The core working principle is to decompose the traditional integral window frame 200 and the outer frame 100 into adjustable base plates and extension components. The plug-in telescopic plug 301 is used to flexibly expand the window size on site. The window frame base plate 202 and the outer frame base plate 102 serve as fixed reference structures. Four splicing plates can be quickly plugged together through the splicing plug 302, and the adhesive can be injected through the glue injection hole for firm connection. The telescopic adjustment of the window frame base plate 202 and the window frame extension 203, and the outer frame base plate 102 and the outer frame extension 103, in cooperation with the telescopic plug 301, can accurately compensate for the building opening size error within the range of 0-50 mm. This not only retains the integrity of the factory prefabricated finished window (transporting and installing the whole window), but also avoids the dependence on non-standard sizes in traditional customized production. The window sash is hinged to the window frame 200 through the hinge 400, and the limit rod 500 controls the opening angle. The safety protection system adopts a dual locking mechanism: at the physical level, the mechanical interlock between the spring buckle 601 and the spring buckle 601 is used, and the elastic deformation of the pre-compressed spring is used to achieve automatic locking when the window sash is closed. An unlocking threshold of ≥50 N needs to be overcome for external force breakthrough; at the electronic level, the electromagnetic lock 602 and the Internet of Things module are integrated. When the window sash is opened without authorization, the electromagnetic lock 602 triggers a power-off release signal, and the remote alarm system is synchronously started to form active defense. The double-layer thickened glass 205 adopts a laminated hollow structure (such as 5 mm tempered glass + 1.52 mm PVB film + 5 mm Low-E glass), combined with the three-way sealing design of the airtight rubber strip 204 (204), which not only improves the impact resistance strength (reaching the EN356 P5A anti-theft level), but also optimizes the sound insulation and heat insulation performance (heat transfer coefficient ≤ 1.6 W / (m 2 ·K)). The push-pull handle 700 (700) is internally provided with a torque sensor, which is linked with the electromagnetic lock 602 to realize the feedback of the opening and closing state. All security data can be uploaded to the cloud platform through a wireless protocol (such as ZigBee or NB-IoT). During on-site installation, the construction personnel only need to slide the extension part according to the actual opening size, insert the telescopic plug 301 and lock the self-tapping screws to complete the adaptation, without on-site cutting or welding, and the installation efficiency is increased by more than 60%. Through the deep integration of structural adjustability, security intelligence and production standardization, this design not only solves the problems of long customization cycle and high inventory cost in traditional processes, but also upgrades the doors and windows from passive protection to active security nodes through the embedding of Internet of Things technology, realizing the full-chain technological breakthrough of "factory prefabrication - on-site fine-tuning - intelligent joint defense".
